Usually charge my Tilt over night. But just to check it I unplug it before going to bed.
Started at 100% when I went to bed, I got up 7 hours later and it was at 56%. That is far worse than I expected!
Is this normal? Or shouls I restore it back the the original ROM and exchange it while I still have time.
What did you have turned on? If you leave Bluetooth and WiFi on overnight it'll definitely kill your battery... you should disable them in the commanger when not in use to save battery life.
Also, if you have the mail client set to check for new mail often (every 5 minutes or so) it'll keep firing up a data connection which uses the battery.
Thats certainly not normal. check if you dont have Wifi or an 3G connection at the moment.
I did have bluetooth on. I am on a 3G network, but not connected to a data session.
I had this problem with one of the 'cooked' roms. For the 5 weeks I had my phone, I never had a problem with it draining overnight. I flashed one of the roms, and two nights in a row I woke up to a dead battery. I reflashed the ATT rom, and haven't had a problem since.
Overnight battery drain
I have a tilt, std AT&T rom, with some modifications and updates, found here. I have pop email service running every 15 minutes, and commontime Mnotes push email to my lotus notes files and email, bluetooth on at all times. My overnight battery drain, 8-9 hours will be from 100% down to 89-92%, so I would say there is something else wrong. If you have "battery status" (found in this wiki) on your today screen, it will show you battery drain. You should also have the tweak settings to turn off your 3G connection after 1 minute after completion of data transfer. If this does not do it, go back to the OEM rom and then add your updates.
It should not drain the battery like you are seeing, my reference as a guide and I push my phone pretty hard for data and email.
Good luck,

Totally agree.
there is also the posibility that you have a defective battery that's not holding charge. If you check with your phone supplier and tell them nicely that's the problem they will most likely give you a replacement (as they will send the old one back in the packaging as a return).
OK, I'll flash back to my original AT&T ROM and see what that does. I have another batter (1650 from ebay, a cheap one) but don't expect to have it for another 4 or 5 days.
it's a shame because I really like this Dutty's ATT Beta 2.
Anyone have a good full featured ROM their using that I can try if I find the AT&T original give me better battery life?
My overnight drain with bluetooth On and band set on EDGE is 4%. The only times I've found it low to dead overnite is when I've left WiFi On, not sure why as it should standby when off, but at least twice it's sapped the battery dead.

I wonder if when you get below a certain crital % battery level that cellphone or any Tx/Rx connection drops off? I have noticed once before (and never associated it with anything) that when I was near an audio device (my PC speakers are best for this) and my battery was low that it was 'polling' the cell network like crazy as if losing connection! This may also work for WiFi (which in sleep periodically checks if the network is still in range) and BT?
Something to investigate!
Overnight, around 7hrs, from a 100% battery with BT always on Wi-Fi off, 3G always connected and it's setup to check my email every 2hrs, I only loose 1 to 2% battery life and my alarm going off for about 5mins , this is with the Orange HTC Tytn 2 using their original ROM
Wel, I flashed the latest Dutty's ATT touch ROM. My battery did improve.
From 100% to 78% over night with bluetooth on. Not great but much better.
I'll see how it goes tonight.
My overnight drain is typically 5-7%.
This is with e-mail poll every 5 minutes, so data connection is on.
Bluetooth & WiFi off.
OK, checked it again this morning and this time at was at 98%!
I couldnet figure out why the day before it was at 78% and today at 97%. everything was the same (or so I thought).
I noticed later that the Radio pluging (to toggle BT, WiFi, and phone radios on/off) was not on my today screen. It was set to, but apparently didn't load. Maybe that is somehow the issue. I'll keep it off all day and see it I don't have more juice at the end of the day than usual. I'll turn it on again for tomorrow and see my my battery drains quickly again.
I think the battery capabilities may have a lot to do with this.
Anyone here use Li-Polimer for anything else? I do, minature 3D (no pun intended!) RC helicopters, and the individual packs NEVER produce the same charge/discharge cycle..
Not one is the same from purchase.
Some packs can devolve a low current without much adverse effect, others can charge with a greater sustain. If you present a charge cycle whilst discharge is taking place, it can effect performance.
Lots to look at here guys including device settings but when you put all these aspects together, as in this thread, there is something to work on...
I could've swore that when you turn your phone on stand-by (press the power button on the side to turn the screen off) that it also disables wifi until you wake the phone up.
I was having this same issue. Turned off Bluetooth and Wi-fi at night, hit the power button on the phone and now it only drains about 3% in the 6 hours I sleep.

It does unless the ROM you install changes the registry keys or you do yourself.
ah, okay.. well as long as the battery life lasts longer than the tytns then i'm happy
don't forget the default design of WM !!! ( X does not closes running programs ) ... get a task manager and make sure X DOES fully exit
I had to add that in to cover all the bases
This took some hunting down so have documented here in case others are not already aware. The Diamond defaults to leaving 3G/GPRS data connections turned on all the time, once it has connected for the first time since turning the phone on. My battery life was terrible until I changed this to disconnect after 60 seconds - the battery life is now great.
GPRS/3G Auto-Disconnect
Just change 2 registry entries in the following part of the registry (download Resco Explorer if you need a registry editor):
HKEY_LOCAL_MACHINE\Comm\ConnMgr\Planner\Settings\
1) Change the DWORD "CacheTime" to the number of seconds the connection should remain active (I use 60 seconds)
2) Change the String "SuspendResume" from "~GPRS" to "GPRS_bye_if_device_off" (without the quotes).
That's it. This solved all of my battery life issues.
I'll give it a try...thanks for the heads-up
or use diamond tweaks app
Not much good if you use push email though...

Such a useless suggestion...the GPRS connection doesn't have almost any impact on the battery life if the connection is open or not.
Only if data is trasferring it makes a substantial difference, so if you are working with push mail, whatever parameters you change it is useless. Otherwise, if you browse the web like crazy, again - useless.
The battery cunsumption of this device is ****, period. they probably weren't able to stabilize the chipsed properly, since it gets hot every time you activate the display, like gaming or other features unrelated necessarilly with the Radio.
If you are using Push mail, it indeed is a useless suggestion. However, if I'm checking my train schedule in the morning, and don't do anything else except possibly cal with it, is IS a useful suggestion. Not having the connection established IS more battery efficient than not having it on. It's like making an argument that turning the phone or wifi off would NOT save battery life. Yeah, right. By the way, my device does not get hot at all, except when charging.
mmmmh on my O2 Germany branded phone this setting was already set to 60. What is the default Setting on unbranded phones? I want the GPRS Connection to stay on, as my provider charges the traffic in 10kByte steps.
Disconnecting your dataconnection does indeed dramatically improve battery life.

You probably don't use GPS. After 10/20 minutes of GPS with these temperatures outside it does get hot.

They talk about GPRS not GPS if I am wrong.
GPRS does not effect much of the battery.
GPS affects alot of the battery when used.
Grtzzz
I don't see how having GPRS or push email connected all the time and not effecting the battery life. Once you have the connection open the phone/server is constantly sending/receiving packets of data back and forth(syncing) , although minimal if no email is going or coming. Yes it effects battery life big time because its using radio and cpu power. On the other hand GPS i agree it kills the battery life. period.
Thats what I mean normaly the GPRS is sleeping until you decide to go on the internet or look after the weather.
I agree when you use pushmail or other aplications which force the GPRS continuasly to activate its going to cost a lot of battery power.
But when you use it normal to look after the weather sometimes or internet sometimes you can leave it on. It will not drain your battery for life.
Grtzzz
Have to agree with daraj.
The Diamond battery gives me about 2 days of usage between recharges (I don't talk much).
If the GPRS is on (even if I'm doing nothing with the internet connection), on the other hand, the battery last barely 0.5 days.

I have GPRS on all day long, talk in the phone a couple of times a day, listen to FM radio for maybe 20mins/day and use push mail where i get maybe 20-40mail a day.
I have 1½-2 day on a fully charged battery with my Diamond. I dont find that too bad - actually a lot like my old HTC Trinity.
Battery life too bad
I had Diamond for a week. Battery life is just crap to a stage I am afraid to use it. Initially I thought that I was playing around with it thats why the battery is draining. But today I was doing a 13 hour shift I hardly used the phone except making 3 calls lasting couple of minutes each. Battery was full in the morning - charged at night. By the end of the shift the battery was down to 10-20 percent!! I was so shocked to see this. Without even using the phone, the battery just drains, I dont know why. So, disappointed with it now

eh? You serious?
God dam it this is the worst phone ive had, even my old n95 lasted longer than this.
All ive done today was a little Wlm, sent 11 txt called about 4 times only afew mins. Mind you i did test out the gps with tomtom but that was a 5 min drive down the road. Ive had to charge it 3 dam times today.
I cant wait for my genuine extend battery to turn up.

I've had the phone for over a week now and to call the battery life good would be an overstatement. It is however adequate. I talk on average 1-2 hours (3G only), use poll mail (30 minute check intervals), use the browser and GPS for perhaps an average 20-30 minutes per day. At the end of the day I usually have 50-60% of the battery left. When left in standby with just the email checking, it consumes little.
Only once did I get excessive battery usage and it's an incident I can't explain. I left it overnight in standby with no programs running and the battery level dropped from full charge to 50% in the morning. It hasn't happened since.
In fact, while the battery life certainly has been inferior to my previous phone (Nokia 6210) it's much better than on my last WM phone (Mio A701). After having read reviews and user opinions I expected it to be worse. It's not good, but it is hardly disastrous.
Hi all, I just got my HTC Pure over the weekend and I had a question from those with more experiecne.
First I know (or I think) that the battery life will improve over the next week or so as the battery gets used and charged. Today however was an issue. The phone came off the charger this morning at 100% and then went to work. While at work there is absolutely no signal in the building. (never has been) The only time it was on the network was a 1 hour lunch, and then light internet use for approx 25 minutes this evening. That is all, no calls, nothing, and it had 19% battery left in only 12 hours off the charger.
Again, I am sure that it will improve, but the question is ... does being off the network (GSM) drain the battery faster? Does the phone use a lot of charge "searching" for signal?
I am sure that there are a lot of things that I could do to extend battery life, as a work around (no bluetooth, plug it in to the USB on the computer at work, turn off 3g etc) but I was just curious if someone in the know on how the network and battery use go together if the dead zone is the biggest problem.
Thanks
Not exactly scientific results, but before att put decent coverage in my neighborhood, the battery seemed to drain a lot faster. I guess turning it off would help, but down to 19% that quick just seems ridiculous

Funny enough it is my wifes first smart phone. I was just looking at it to change some things to better suit her needs. When I opened the task manager I discovered that a) the programs would only minimize when the X button was pushed, not close and b) windows Live messenger was loaded. I would guess that even though she was not signed in on live messenger it could have killed the battery. Gonna make a couple of tweaks to ensure that it does not fire up again, and see what it looks like tomorrow.
So today was better, but she seems to have had intermittent service. Her media net indicates that it was connected all afternoon. She burned through 40% battery in the AM and only 18% in the afternoon.
I would imagine that the location services for the weather on the sense home screen as well as possibly push email running out of control searching for the signal. I will turn things off 1 at a time until I find out what is driving the battery loss.
Is there any software to monitor battery use and what was using the battery? There is in android.
O.k. continue to have issues with this phone.
Tested last night. Charged to 100% and then light use. Approx 10% down after 3 hours.
Set commmanagerpro to turn off the data and phone radio during the hours my wife is at work. She called today and the screen is showing that the phone radio is off, but it has lost 90% in less than 4 hours. She also said it is hot.
Maybe her purse is somehow turning the screen on? Would the screen being on without any radios cause the phone to plow through battery?
I am gonna try a battery monitoring app and see if it will tell me anything. Its freekin weird.
What radio version are you running?
You may want to consider flashing to a different Radio ROM.
try to see if there are any TSR, residente program, active, maybe be the the problem...
as far as radio versions the 4.49.25.91, for my exprience run far...
you can try to swcht to other radio version...
I am using the AT&T stock radio. I flashed to the energy ROM, but the battery issue is so extreme that I doubt that the radio or the ROM are the driving factor.
She does have 3 magnets in her purse. 2 magnetic catches on her side pockets and 1 on her wallet. While I could not reproduce the device turning on by itself from the magnets, that does not mean that it is not.
The other thing is that there was some warning on the screen about the GPS signal. I imagine that is a side effect of turning off the radios, but maybe not. Is the GPS always on normally? Would a GPS pop up cause the screen to stay on for possibly 3 hours.
This afternoons test will be having her leave her phone in her jacket pocket rather than her purse. We will see how it goes.

I will look at that radio. I doubt its a program since I had no problems with it at home last night. It has to be environmental. My money is on the purse, but we will see. I'll post later and let you know what we came up with.
There was a few days ago where she lost 60% of her battery in the morning but only 12% after lunch, so that convinces me that it should be something that we can identify and work around.
Energy's ROM may have included the radio.
I had horrible luck with .91 and flashed back to .17.
Symptoms of a bad radio are rapid battery drain and device heating up.
Also, if the device heats up, it will no longer charge until the battery cools down.
If you have AGPS enabled, that was likely your error message when you turned off the radio.
A couple of pointers;
Make sure you monitor which programs are running as you may just be minimizing instead of closing.
Check your power settings and make sure to turn off screen after X minutes
make sure all updates (weather, e-mail, stocks, etc) are set to every hour.

Thank you for your advise. The biggest area of opportunity from your list for me is the Radio I think.
The rapid discharge of the battery due to a bad flash, would that be location specific? The rapid drain only seems to happen in a spot where she has no signal (thus the reason I programed it to turn off the radio in those hours)
The running program should no be an issue. To prevent that, as a matter of standard setup for my phones, they have a small script that soft resets them every morning a 4am, so that they are fresh and clean for the start of the day.
As for updates, I have adjusted everything that I can, and some did not have any effect (mostly because the radio was off, can't save much more than that).
I do leave the bluetooth on all day. That should not be draining the battery in 3.5 hours though. I have read a lot of the battery life threads and many of the ideas would cripple the phone, and I am not going there. Sure maybe I don't need weather updated every 30 minutes, but I want me email when it comes in, not once every few hours. I also don't want to have to push 20 buttons each time I want to make the internet work. Its this kind of usability that sells iPhones... I hate them, but they really do just work... and my wife wants a phone that you don't need to be an expert to use.

Do you know how to view your radio version? Its listed on the bottom of your phone when you reset, the 3 numbers that display, R is the radio version.
You can go to the radio thread and flash another version, just keep testing different versions until you get one that works well. Radio ROMs will not overwrite your data.
Radio's are definitely location specific in regards to region and carrier.
Borderline coverage is a major battery killer, but you're disabling the radio, which should resolve that issue...
G-Profile is a nice app that allows you to set what type of connection and when.

Mine didn't and I used the May 1st update. Still Stock.
If no signal is happening in the building, I would think it's the various things continuously trying to run, like Email, GPS etc. Constant failed attempts to update your phone's apps would definitely drag the battery down in a hurry. I have my email set to 3 hrs. updates along with weather updates. Nothing I do is so important at this point in my life that faster than 3 hr. responses are required. I also don't use things like Tweeter and FaceBook so those aren't constantly eating my battery. I get about 1.5 to 2.0 days from my battery currently.
Here is the current (no pun intended) testing results...
This AM 3.5 hours used 100% of the battery (in the purse)
This PM 4 hours used 21% of the battery (in the jacket pocket)
Gonna try to leave the phone outside of the purse all day friday and see what the results are. Then see how it works around the house on saturday, in a standard limited use type scenerio. Then Sunday put it into the purse and see if it becomes an issue again.
If all of this works out that the purse it the problem, then I will start tweaking it out, and changing radio's etc to get the max I can out of the battery.

So today we left it out of the purse. Here is what we got...
On the table next to the computer, so confirmed that the screen is NOT activating at all. Phone radio off, data off.
AM... used 40% in 4 hours.
Better, but still not good. Gonna try to ensure that the email is set for longer, currently it is set for 10 minutes, and then try to turn off a-gps and the regular gps and make sure that those things are not killing the battery. Then flash a new radio. We'll see how that works next week.
First, test it and watch it over normal, with signal, average 4 hours at home this weekend. I think it will do great... meaning that it is the purse, or the environment that is causing the problem.
I don't know if anyone is following my personal drama, but maybe it will come up in a search some day and help someone.
Here is the saturday update.
Took the phone off charge at 2am and looked at it at 11 am this morning. Used only 2% in those 9 hours. So it is definitely NOT a defective device, or battery. (it actually charges up in only a couple of hours)
So looking into the profile schedule manager that I installed, turns out it has not been running. So the whole purse/no purse thing may be horse hockey still. Monday I will be setting it manually to airplane mode to verify that it holds a charge, then finding a new program to do the scheduling. (looking into phonealarm)
If the radio was on, at full power searching for a signal, it would only last approx 4 - 5 hours at best. So it makes sense that this is what is happening.
Before anyone accuse me of it, I did, in fact, look through the other battery threads on this forum (and other forums, for that matter), and I've already applied numerous tricks. I managed to get my phone to last roughly 9 hours from my typical usage, which now makes it comparable to other phones I've used in the past.
However, in about a day or two, I'm going to be getting a bluetooth headset...which basically means that I'm going to need to keep the Captivate's bluetooth on 24/7 (or, at least, most of the day). I really don't know how much battery this is going to cost me on the Captivate, so I'm trying my best to make things better now to make things smooth in the future. However, I appear to be at the end of my rope.
I have pretty much gimped the Captivate as much as one could reasonably take (more, I'd dare argue). I cut all of my volume down to half of what it was and I removed most of the quick icons. I also set a completely black wallpaper, I turned off all animation, and I turned the brightness down to its lowest setting.
I honestly don't know how to make it any worse. The SAMOLED screen is basically a meaningless PR term to me now and I'm actually missing phone calls from sheer lacking of hearing my phone ring...despite it being right in my pocket.
Going even further, I also attempted to switch to ADW.Launcher based upon recommendations by others that it increases battery life (I found that it had little to no effect). I also attempted to severely underclock my CPU (down to 200Mhz) based, again, upon other claims that it increases their battery life all the way to as high as 30+ hours on a single full charge.
Somehow, underclocking my CPU actually made the battery die out faster.
Furthermore, I attempted to use programs (SMODA, 2G/3G) which claim they allow me to switch to EDGE because, for some God-forsaken reason, Android doesn’t seem to have any toggle for doing it. Unfortunately, none of them seem to work; rather than switching to 2G, they all just completely disabled data, which, unfortunately, is completely unacceptable to me. So at this point, I only seem to have a few more extreme (from my perspective) options. Once I actually get the bluetooth, I plan to turn off most of the auto-updating apps (email, weather, twitter, etc), and just update them myself periodically. Furthermore, I plan to turn off the GPS location feature once I get my GPS unit.
Beyond the above, though, as I said, I'm at the end of my rope. Once I employ the other tricks, I figure I might be able to stretch battery life to 9.5-10 hours, but I would like to go even further. If anyone could offer me some help, I would highly appreciate it.
if your gonna have a bluetooth headset on disable your ringtone completly that would be meaning less. if your near wi-fi a lot have it connect only though that.
also you can clock the cpu down to 100Mhz along with the GPU.
AND to force 2G/edge read my howto in general
oh the ext2 lagfix can also save you some battery life

I'm already doing the first sans disabling ringtone. I'm not so sure doing such a thing would be acceptable to me.
As for the underlocking suggestion, as I said, I underclocked the CPU all the way down to 200Mhz and the battery actually drained even faster. I doubt underclocking even further is going to help. Furthermore, I actually did try 100Mhz originally, but the performance was so horrendous that it was unbearable.
As for the lag fix, I already have it. Lastly, I knew about that 4636 technique to switch to 2G already, but, unfortunately, it doesn't appear to work for me. The setting doesn't save and 3G still remains.
EDIT: I actually found a way to make the above work. Simply dial *#*#197328640#*#*, then go Debug Screen > Phone Control > UE State Control > Change RAT to GSM. This will actually force your phone to use GSM only. This seems like the answer to all of my battery problems....except it doesn't work. Once you make the change, the INFO menu reports that it has been changed to 'GSM Only', but data appears to have been disabled. Restarting your phone makes data works again, but the INFO menu reported that data has been reset back to 'GSM/CDMA auto'. Yay.
If you haven't already, turn off GPS when you aren't using it. Use the Power Control widget to help. Make sure all of the things in the power control widget are off unless you are using it. And use advanced task killer if you haven't already.
i say screw underclocking let run at whatever i dont think it makes a difference.
forget advanced task killer, i like auto killer.
leave gps off unless needed, and backround data
switch to 2g when you can.
no live walls of course use dark or black, no updating widgets
i dumped stuff like juice defender, cause with backround data off i dont think it does anything.
flight mode it at night (when sleeping) if not charging
ive been running jh3 (now jh7) with sre. get to work (i run 2g at work)at 9am listen to pandora all day through bluetooth (which is on for 6-8hrs) and wifi (6-8hrs) good amount off browsing bout 30 min of voice calls, some texts email checking, more browsing, some games. on average lately after being unplugged for 13-17 hrs at the end of the day with 20-30% life left,using bout 3hrs of display, 30 min voice calls, bluetooth doesnt use crap bout 3%, media server usually 15%, cell satndby i wanna say 10%, im pretty happy i guess, even though im always lookin for better results, tryin the new sre with undervolting, heard some good things.
still when that seidio 3200 mah battery comes out im gettin it, dont care how fat it makes the phone, things to dang thin as it is, and without some sort of cover its like a wet bar of soap!!
What is your typical daily usage? I have fairly light usage (few games here and there a little music and a good amount of web surfing, app browsing and texting with a few phone calls using speaker phone) and I'm at 28 hours of use with 55% battery.
I have just the typical power saving tricks(gps off, bluetooth off, screen at minimum or 30% and my data doesn't sync automatically), no under clocking or anything. I should point out I'm running a euro galaxy rom and am not ever on a wifi connection.

Wow you are lucky. Yesterday I got 2 phone calls for a total of 3 minutes. I sent 7 text messages. I surfed the web maybe for 15 minutes. No games. Nothing else major. GPS off. Bluetooth off. Wifi on. Screen at 22%. Only background data I have is email which checks once every hour and a weather widget that refreshes every 6 hours. I got barely 12 hours in before my battery died.

Typical usage for me runs along this line: A lot of web browsing, perhaps 30-45 minutes of music, and plenty of IM. I also use Aldiko to read now and then. Calls do factor into this, but typically only two or three 10-15 minute phone calls.
Truthfully, I simply don't see how it is possible for you to use the phone for 28 hours straight and still have 55% battery. I could lose 30% battery just by leaving my Captivate on stand-by for 30 hours.
I certainly understand the interest in having the best battery life possible.
Are you in a work environment where you cannot plug it to a computer for part of the day?
Fortunately, I am. And I always have it plugged in in the car.
I don't want to have a powerful phone with all the features turned off in order to keep it going.
I dont see how you can get 28hrs @ 55% either, with the kind of usage he was claiming, i wouldnt exactly call that light usage

Well, I do have a work environment where I can keep my Captivate plugged in, but only half of the time. Other times, I need to move. Aside from that, it kind of annoys me to use a phone attached to a wall socket. I prefer to keep my smartphones plugged in only long enough for them to fully charge (or at least charge to 80+%), then unplug them for usage. This is kind of tough for the Captivate considering it takes 3-4 hours to fully charge.
I also fully agree with you on the last point, which is what makes all of this so frustrating.
*Sigh* It's really too bad the Captivate is my first Android phone; it's been kind of a negative experience for me so far. Ironically enough, the one issue that hasn't been a problem for me is the one issue most seem to be having -- GPS performance.

I am in class for most of the day so the phone is idle most of the time but i only play about 10 minutes of music with about an hour or 2 combined web surfing and games but my phone is still chugging at 39 percent battery life at 38 hours of usage. I guess that qualifies as light usage then.
edit: jm6 with unhelpful kernel and sre
also, you have let the battery die out completely and recharge completely with the phone powered off correct?

I'm honestly shocked at your usage. Am I reading right that in the 38 hours since you last charged it, you only used it for 10 minutes of music and a combined 1-2 hours of web surfing/games? I wouldn't call that light usage. I would call that hardly any usage.
Under such conditions, I can see why your battery life lasts so long.
I don't see why you can't get a days worth of usage out of your phone. Cell phone calls use the most battery - that is why the phone is rated at about 5 hours of talk time. This would be in the best signal area. If you are in a lower signal environment (especially in a heavy building all day) you will see faster battery drain.
I am not sure why you are bothering with BT if you are only talking on 2 or 3 calls - but if you take 3 15 minute calls that is at least 15% of your battery - the only way to change this is force the phone to Edge.
I would not lower ringtone volume - that is not a big battery saver in the grand scheme of things and you are missing calls - not a good trade off. If you are doing a lot of web surfing, go WiFi instead and you will see big battery imrovements. 3G voice and data suck battery - it doesn't matter if you have android or iPhone.
If you put your phone in Airplane mode you can go for 5 days between charges with minimum use.
The radio does kill the battery, I don't think the battery usage screen really depicts this. Since I've gotten my captivate my old BB Bold (at the time would only last 3 hours due to its degraded battery) lasts days on end with its radio disabled while sitting in my desk. I'd love to see native 3G toggle or at least a captivate catered app, I'd even pay for the latter

Well, that rating is probably the battery life if your decide to talk on your phone for five hours straight. I really, really doubt it takes into consideration the in-between times (games, apps, and, of course, web surfing). Phone calls undoubtedly takes the most amount of battery, but Internet usage is probably second place and, as said, I use that fairly often.
Lastly, I'm not planning to use my bluetooth exclusively for phone calls. I'm going to use it for calls, listen to music on the Captivate, chat on my PC, and so on. It's multi-usage.
Next, you're missing a lot of the things I said. As I said, I already tried numerous methods to force the phone into 2G; not one of them works (they either don't work at all or actually completely disable my data). I'm already using wifi as opposed to 3G as much as possible.
Lastly, I'm sorry, but using airplane mode to save battery is not acceptable. If I'm even willing to consider this, then I might as well just turn off the Captivate to save battery.
I just read something about an external sd card being another battery drain.
Took mine out and we will see. I was already getting through the day with about 20%left.

I didn't meant to suggest that airplane mode was an alternative, just to point out that the cell radio for Voice and Data is your biggest drain.
If you are going to use the phone for almost an hour of talk time, heavy web surfing and BT connections for tethering then your battery life will be limited. If you are using BT to chat on your pc - then maybe tethering with USB would be better - you could charge at the same time.
Your other option is to get a spare battery.
And I did read what you had to say, I just didn't realize how much you were expecting your phone to do. The only numbers your provider were around talk time.
I use my phone a lot and I charge it every 24 hours - I am more then satisfied - but I know that if a spend an hour or more talking on it and bunch of web surfing that I will have to think about charging it as my usage increases.
There is a way to force the phone into 2G. It isn't very user friendly. I have tested this and it works great.
Enter the Phone app.
Dial *#*#197328640#*#*
Select [1] DEBUG SCREEN

Anyone notice a change in their battery life in the past few days? My girlfriend and I both are going through our batteries in just over half a day with no use. It's like the phone isn't sleeping. Looking at battery use Display is using all of the battery. I'm running CM7.0.3 and she's on stock. Looking at mine right now the phone has been on battery for 1 hour 34 minutes, and Display is taking 57% of the battery and I'm down to 84% battery.
Yes! I've had my N1 since January 2010. I stayed stock until recently when I installed CM 7.1 RC1 shortly after it was released. Battery life had always been great, both stock and under CM7, especially with SS4N1. Then, a few days ago it just fell off a cliff. I now get only about 7-8 hours, even with little to no usage. Before I'd barely lose anything if the phone wasn't being used (a percent every couple hours).
Now the Nexus One Battery Calibrator application shows a drain of ~200 mA or more constantly.
I've been tearing my hair out for the last few days, uninstalling apps right and left, trying in vain to figure out what's causing this. I even considered a full wipe and reinstall of CM 7, thinking that some system setting somewhere had gotten horked.
I've always had WiFi set to never sleep, since I'm usually either at work or home. I've also had preferred network type (*#*#4636#*#* -> Phone Info) set to "GSM auto (PRL)" for months.
I've not made any other changes I can think of that would've had such a drastic impact on power consumption. I didn't track all the app updates that happened around the time it started, so I suppose it could be one of those. But I've uninstalled just about everything and it's still happening.
I have the same issue! Just in the past week or so. I have about 50% battery then a hour or so later it's dead! I was going to get a new battery today but maybe it's a CM7 issue. I use the nightly as soon as they hit the mirror.
An update on this... There may be a big issue going on with T-Mobile or some recent update:
http://www.tmonews.com/2011/07/t-mobile-g2-users-suddenly-suffering-from-huge-battery-loss/
Looks like other users on different phones have the same issue!
Thanks for that article, Lost Dog. Makes me feel a bit better. At least I know I'm not just going nuts.
My phone still has increased battery drain even if I put it in airplane mode though. It helps, but it's still much faster than before. This makes me really puzzled as to what the cause could be. How could the cell network still be causing increased drain if the phone's completely disconnected from it? Some sort of configuration information it received that persists even after the cell radio is turned off? EDIT: I may be wrong on this one, see below.
Last night I tried a complete wipe (using Temasek's full format "Format-signed.zip" first), and re-installed CM7.1 RC1 completely fresh. I installed only the minimal Google applications and a couple crucial tools (my password safe app). However, I'm still getting the same quick battery drain today.
I hope we (or T-Moblie) can figure out how to fix this. It really cripples my phone as a useful tool to have such short life!
EDIT: I'm going to try a workaround I've seen mentioned in comments on the TMoNews and Phandroid articles about this: limiting the cellular connection to 2G/EDGE only. It seems to have made a significant difference so far. I may have been incorrect then about airplane mode not having an impact. I'd only been checking current drain with the N1 Battery Calibrator app, and never left it in airplane mode for long. Anyway, I'll post back later this afternoon with results.
Ok, so switching to 2G-only for the cellular connection seems to have made a HUGE difference. The drain rate seems to be back at around what I'd expect. Everything else I left exactly the same (WiFi on, GPS enabled, same applications, etc.)
So, I'm starting to suspect something may be up with T-Mobile's 3G/3G+ service in some areas that's preventing phones from idling properly.
Anyone else want to give it a try?
Interesting, I'll switch over to 2G only and see how that affects my phone.
I've gone as far as wiping everything and that didn't help so if it really is a t-mobile issue then that would shed some light on the situation.
I see the same trend when switching to 2G only. Very steep power usage with 3G then a dramatic decrease in the discharge slope in 2G.
T-Mobile has an issue. The trick will be getting someone there to listen.

Here is my screenshot. You can clearly see when I turned on 3G. Dramatic difference. Looking on the T-Mobile forum there are many people seeing the same issue but there's mostly finger pointing and speculation as to the cause.

I also got the same rapid battery drain since last Wednesday. At that time, I thought there may be a hardware/battery issue for my nexus one. To test this, I switched my rom from CM7 back to GB stock. After a few updates for the GB stock and used it for a day, same battery drain happened. So, I changed to use another backup battery yesterday. It did not help also. I thought it may be a real hardware issue.
Then, I found this thread and research a bit in the web. I found out it could be either caused by tmobile or google map updates. I first uninstall google map and reinstall the new version right from the market again. I also switch off 3G as well. No rapid battery drain for the entire day. The battery runs normally. When I came back home today, I turned on 3G, let it for a couple of hours, checked a couple of emails and received a 20min phone call. Everything seems to work fine. No noticeable rapid battery drain was observed. My conclusion so far is: this is caused by google map 5.8 update.
Try to uninstall it and reinstall the google map from the market to see if it helps.
Good luck.

Well, I'm willing to give it a try, but I'm skeptical. If it were the Maps 5.8 application that was preventing the phone from idling correctly, or transmitting tons of data, wouldn't we expect it to happen regardless of whether the phone was using the 2G or 3G radio connection? Sure, there might be a slight difference in the drain rate, but we'd still expect to see it in both cases. And yet the accelerated drain is alleviated completely by using only 2G. I have the Maps 5.8 application and can fix the problem by using 2G only. That indicates to me it's not an issue with the application.
I'll try uninstalling Maps tomorrow (I'm using CyanogenMod, so it's possible to remove it completely). Then I'll put the phone back on 3G and report back on what happens.
I've been experiencing similar battery issues the past week or so too. It looks like turning on 2G only seems to fix it, but what I don't get is why I'm still getting horrible battery life?
I have tasker auto turn off my 3G all together whenever my screen is turned off, and yet I leave my phone on my desk untouched all day and I end up at 40% when I get off work.
Wouldn't turning off 3G via Tasker be the same (or close to it) as turning on 2G only in the settings?
Hope t-mobile gets this worked out pretty soon!!
Glad I saw this thread. My wife and I both have N1s and have each been noticing unusually fast battery drain just in the last 3-4 days.
Last night I charged both phones to the same percentage, turned off 3G on hers and let them both sleep for a while. The phones are configured pretty similarly (stock, latest Maps installed, similar push settings etc). After about an hour and a half, my phone had lost 11% of its charge and hers had only lost 2%. That's enough of a delta for me to point to the 3G usage as the culprit. I guess I will be leaving my phone on 2G when I'm not using it if I am going to be away from a charger for a while.
It's NOT the Google Maps update.
Well, I did my experiment yesterday to rule out the Google Maps 5.8 update as the cause of this issue.
I'm running CyanogenMod so it's possible for me to uninstall Google Maps completely, not just the updates. I did so on Saturday night. Still set to 2G only, I removed my phone from the charger Sunday morning. A few hours later I enabled 3G. Later that afternoon I turned 3G off again.
I think the screenshot speaks for itself. Again, this is without Google Maps installed at all.
I asked around this weekend, and my friend's wife (also here in Portland, OR) is experiencing the same issue on her G1 on T-Mobile. Reading online I've heard about the problem affecting the MyTouch 3G, the G2, and many here with the Nexus One. The common elements seem to be: T-Mobile 3G service, particular models of phones, and some particular geographic areas.
Bottom line (IMHO): T-Mobile has a problem with the configuration of their 3G service in some areas, and it's preventing many phones from being able to idle/sleep properly, resulting in huge battery drain.
Here's mine, I posted this several days ago in the TMONEWS thread.

That's interesting. Even locking the phone to 2G/EDGE didn't have an impact? (not a Nexus One there it appears, what model?)
How did you go about disabling the 3G connection? I'm not sure if there are multiple ways to do it, but I used:
Settings -> Wireless Networks -> Mobile Networks -> Use only 2G networks
Really strange that even pulling the SIM didn't seem to make a difference. Or maybe that's not the same as turning off the cell radio entirely? Perhaps the issue is lower-level, like the radio constantly polling the tower or something even in the absence of being able to successfully register on the network for active use.
Does enabling airplane mode fix the drain issue for you?

This is a G2.
2G has been much better than 3g, but still probably only 3/4 of my former battery life, optimistically. I checked "Use 2g networks only", same as everyone else. The graph above is a little misleading, since I really saw better battery life, that initial flat and quick drop actually averages out to "decent", rather than "horrific.
At the "Pulled SIM and SD card" mark I re-enabled 3g, so the drain afterwards is still 3g related.
Pulling the SIM doesn't disconnect it from the radio tower, you can still make emergency calls/etc. so it has to maintain a connection I suppose.
Twice I hard-reset the phone, pulled out SD and SIM, and still had huge huge battery drain. Powertutor said IDLE draw was 1437mw on average, no SIM, no WIFI, just sitting there on my desk.
In Airplane mode it'll last for days...

I'm not familiar with Tasker. However, maybe it's just disabling cellular data use, not actually disabling the 3G radio? From what we've seen it appears the problem is very low-level, perhaps something to do with basic communication/negotiation between the cell radio in the phone and the towers, as there's no indication of particular application activity or significant data transmission that the Android OS is aware of.
In the T-Mobile support thread there are reports that T-Mobile is now acknowledging there's an issue with changes to their HSPA+ network in some areas.
I've had 3G off all day and my battery life is back to normal. I'm at 87% after at least 6 hours on battery. Yesterday I was down to less than 50% by this time. Luckily, I am able to be on Wifi at work so I don't have to deal with EDGE speeds, which make the Baby Jesus cry.
deliamber, you probably noticed this already but I'm also in the Portland market. It's gotta be a network issue.
I'm having the same issue on my N1 (I'm around the Portland area myself)
I did everything as well, 2g is the only thing that saves me..
Can't wait for a fix!
