Ok so if you dont know the 8925 has probably the worst battery life of any HTC phones I have ever used. It was like they decided to put all the latest and greatest into a shell sexier than hell, then give it a old 8125 battery,
The 8125 had what a 1250mAh battery, so they give the 8925 a 1350mAh, makes no since. I am still use to my P990i having a 1500mAh battery and getting 7-9 hours of play time and a 10-18 day stand by time.
Are their any upgraded batteries out yet? if no I may just have to get a second battery and charger cause I cannot go the last 4 hours of my day without a phone. Oh and a car charger is out of the question. I swear those things were made by battery companies to kill you battery faster than shizzit.
Actually, I have found that after a few full charges and running the battery down to about 5% it lasts pretty good.
The first day I had it I had to charge it after about 4-5 hours. Now I am using it most of the day.
if I'm 3Ging and/or GPSing, it goes fast.
if i'm not doing those but doing anything else, it lasts a long time. Easily a whole day.
3G is a huge strain on battery life. Don't expect to get anywhere near the battery life you did with the 8125 if you are using 3G.
With my 8525 I would get 9 hours of battery life at the most (100%-0). With the Tilt, I have been getting about 12 hours of battery life with about the same amount of use.
I run WL push email all day and browse the web pretty heavily.
Make sure to condition your battery by running it all the way down to 0 before you recharge a few times.
I have been conditioning the hell out of my battery so far, 100% down to %5ish, 100 to 5 100 to 5, only charges it and gone through like 3 cycles so far. Hopefully I will see something soon
anyone know of any batteries out there yet? if no I will put an order in for another OEM HTC

lol. that's a trust worthy site.
Just a note - conditioning a LiIon battery has zero affect on its charge capacity.
I'm getting between 8-10 hours of very active use and 10-16 hours of life when I'm not on the silly thing all the time. SPB Pocket Plus calculates my battery life at around 10-11 hours, and it's usually pretty good at estimating it once it's seen enough data.
Nevertheless, I can also attest to the fact that the battery life of my Kaiser is increasing. I'd say its about 25-30% better than when I first started using it a few weeks ago.

Where do you see this feature in Pocket Plus?
I am hoping Slueth is right about the battery life increasing over time. Mine isn't a 4th of what the 8125 or 8525 was. The comments on 3G being a huge drain I can't agree with. The 8525 and 8125 had the same battery consumption and I could get a full day of regular usage on both.
I can say using the Kaiser rom over the at&t rom made a noticeable improvement.
I live in HSDPA nation [Bay Area]. My tilt gets pushed to limits everyday. I have mobile shell installed with weather update, push email and active sync through exchange server, use ICS with laptop on the go. I can get through the day with heavy use and the battery never falls below 40%. At 11:00PM last night, I had 75% left on my battery level indicator.
I would say it's about 20-30% better than Hermes' battery performance.

That's AMAZING! I wish I could have spent 75% by then and still have 25% left. I use everything you mentioned too but I barely make it t 7 or 8 pm before my tilt turns off at 1% battery level so I have to stick it in the charger as soon as I get home from work at about 6'ish.

Add the battery meter to one of your tabs and look at the options for the meter by tap & hold - options. It allows you to set a fixed battery life or use a statistically estimated duration.
The comments on 3G being a huge drain I can't agree with. The 8525 and 8125 had the same battery consumption and I could get a full day of regular usage on both.

It all depends on your actual data usage. If you aren't transmitting a lot of data, then the HDSPA usage won't have a significant effect because it isn't on all that frequently. If you do, you'll definitely notice a difference.
Mine was showing about 75% this morning and is now at 57% (5:30pm) - that is following three or four short phone calls, several web page downloads, several synchronisations via bluetooth and ten or fifteen minutes experimenting with the business card scanner.
I do agree with other comments here that battery life improves after several charge/discharge cycles. This Kaiser replaces my old Hermes - I think the battery life may not be quite as good, but it isn't vastly worse - trouble is that it has so many fun things to play with that you just do more with it! Just the GPS alone will draw that battery down if you use it too much - my hand-held Garmin can flatten a pair of high capacity AAs in less than 24 hours - and that is not powering a 3g transceiver and bluetooth at the same time.

i must say, i have the case of not able to leave my phone in my pocket. I always have to have my phone out, turn on from sleep and do something with it. If I'm able to resist this temptation, my phone can last the whole day going down to 50%. If I'm messing around with it, then it could go below.
I noticed that Skype is a MAJOR draw on the battery.
When I had skype on and logged in, the USB charger could barely hold the charge even ... when I was also using GPS with Google maps the battery life was visibly going down.
After using the device more normally now I get quite decent battery life.
The real test will come when I fly cross country and read an ebook on it.
If i can resist the urge to play with the GPS i can get about 2 days out of mine, but my useage is pretty light. I am using Direct Push with my exchange server, and get about 15 emails a day. The TCP timeout on my firewall is set to 1 hour, so i think that helps too. I am using the black & blue comm manager with 3g option, and i leave 3g off(it switches between 3g and Edge all day at work, and i heard that can lower battery significantly). I only enable 3g if i tether, and even then 3g coverage in my area SUCKS! Verizon has EVDO everywhere here, at&t needs to get their ass in gear . Overall i'm happy with the battery life. I've setup a few PDA's for some of my users here so i wasn't expecting anything great (although our two blackjack users seem very happy with battery life).
Just placed an order for the 1600 mAh Tilt battery
Hi,
I was confused by the different batteries available for the Tilt at www.batteryupgrade.com , so at I e-mailed them this message,
Just found your site, and am interested in purchasing a battery for my ATT Tilt/HTC Kaiser however; when I looked at my battery it does say KAIS 160, but the P/N is 35H00086-00M, and not 35H00088-00M. The device is ATT Branded, and in the device info on the phone, model number just says Kaiser, not Kaiser120 etc. Is there any difference, what battery should I get?
they gave me this link-
http://www.batteryupgrade.com/product_detail.php?productId=75070772&searchphrase=htc%2520kaiser
Just waiting to see if it does help alot, if not, I'll at least have two batteries now! lol

Terrible so far... but i've only been through one charge cycle, almost. I topped off the out of the box battery. From there it's been plugged into the computer while i was adding w***z (i mean perfectly legal software). So I've never actually winded it down to 0.
Is it bad to keep topping it off like this?
The battery life i've been having probably wouldn't even last a day but i should probably go down to 5% before i charge it again and see if it improves.
My motto with this phone is "Who needs decent battery life if you've got GPS, a 3MP camera, an unbelievable library of third pary software, 3G, a fully qwerty keyboard, gorgeous touch screen, and tilting screen?"
Hello, I've recieved my AT&T Tilt 8925 (Kais100) unit a week ago and ever since I've experienced awful battery performance. The item shipped new (not refurbished supposedly nor defective) and included a Samsung battery. I changed to Dutty's v3 ROM right away (flashing was successful, I also switched to radio version 1.27.12.27) and last night switched to Q-Mobile v1.2 to see if the ROM was the problem, but it persisted.
My battery drains extremely fast, even when the unit is off it drops 10% after 8 hours (overnight and also throughout the day, I'm leaving the unit at home while I solve this issue and it's always off). The unit does not have a SIM card inserted and the Phone function remains off, so does WiFi, Bluetooth, Beam, 3G, etc. It's also muted and has no alarms activated, nor background programs running (I'm currently running a freshly flashed Q-Mobile v1.2 ROM with a hard reset done as well).
I've read about battery perfomance extensively but haven't ever read about the battery discharging while the unit is off, and given the fact that I'm NOT using the phone functions, I barely believe this can be normal behaviour. I purchased 2 units from the same source and both are having similar issues with battery perfomance.
I'm currently testing a borrowed OEM Dynapack battery from a friend's Tilt to see if it shows the same behaviour as well to discard the possibility of a faulty unit. Note that I'm using the OEM 1A charger and leave the unit charging for several hours.
If the battery proves to be defective I'd have to get one (or contact the seller to see if he'd respond to the issue). Can someone recommend a cheap/reliable battery that could be bought online (eBay, etc.)?
Thank you very much! I hope that someone has a clue on this issue.
Best regards
Sebastian
Just to clarify, is the phone actually OFF, or is it in standby? If it's in standby, 10% after 8 hours wouldn't be unreasonable at all.
Uhm, it's on standby I guess (when I turn it on again it's instantaneous, not like when you soft reset the unit)...
I'm new to PDA phones, I had an IPAQ RX3715 before with WM2003SE and I could leave the unit off for days without battery drainage. However I may not be too familiarised with these new units' standby/off functioning. If in standby and with the Phone function off (meaning that the device has "nothing to do" other than being off) it's normal for the device to drain the battery so much I would be disappointed.
As a sidenote, my friend's Tilt is not draining while it's on standby being on the same conditions other than the fact that his unit has the Dynapack battery.
Regards!
Bat Drain
I have the same rom and the same problem. I was at the hospital all day i made two calls and about mid day my bat was at 30%. I think its duttys rom V3 causing the problems. Changing roms now.
I could be wrong, but I think your phone is fine, these devices just consume a lot of power. 10% over 8 hours would be totally normal in my opinion. Is that the main reason that leads you to think there is a problem with your phone? Have you ever had a pocket PC before that had better battery life? When I got my first PDA I thought the same thing, but I realized that they are not like normal cell phones, where you could just recharge once every couple of days. PDA's must be charged at least every night. If you use GPS or wi-fi a lot you're probably going to be charging sometime throughout the day as well. I just got into the habit of plugging it in every time I get into the car, and when I get home I plug it into either the computer or the wall charger. There are after market batteries available, but if you want a drastic increase in amp-hours, the battery is going to be bigger and it will require a new battery cover. This is totally unacceptable in my opinion, as the device is relatively large to begin with. My advice would be to only activate a radio if you are using it, and de-activate it when you are done. Also just get into a routine where you are charging it whenever possible. Another thing, I just flashed Dutty's V4 RTM, and I must say the increase in battery life was very noticeable. Don't let me confuse you, though. From the information you supplied, I really am not able to tell if there is a problem or not, so give some more information and examples of battery life so we can figure out if somethings wrong, or if you just aren't used to the amount of consumption of this type of device. Hope I could help. Cheers!

Yeah that's not normal. You got any radios besides phone running throughout the day?
Thanks for your thorough reply. Picking on what you mentioned, it's true that I'm new to PDA Phones, as I mentioned I also own an iPAQ rx3715 with WM2003SE and my idea was to replace it. Judging the fact that PDA-only devices, to my eyes, are nowadays dying I thought I'd get me the latest and most complete device available WITH GPS, since I was using my iPAQ together with a GPS Bluetooth Receiver with much delight.
What I experienced with my previous device was that battery performance was never an issue, it did consume power as any PDA, but I didn't find myself worrying about it, it never dropped when off and it would last me several days.
Since I'm using my Tilt with the Phone function off I _thought_ it wouldn't need any power for anything... but it might be that these new devices, or the new WM6 architecture is different to that of WM2003SE/PDA only devices... I don't know, but it just sounds strange to me, although if it's normal I'll live with it- as you say, I'll have to be charging it 1-2 times a day.
On the one hand it would be good for me to know that my device is ok, but on the other hand it means that battery life isn't even close to what I expected... I had read people complaining about it but in general I tend not to be overly critic about the defects of devices... but it seems that it's the case. I meant not to use the phone features and thus I thought it wouldn't be consuming power on standby seeing that the phone should not be running anything on background...
Thank you again for your reply. If anybody else has a word on this I'd appreciate it.
Best regards
Just as an aside you will notice the battery life getting better after a couple weeks it seems the battery has to be conditioned so to speak. Also do you have any kind of push email on your phone as if you do that does use quite a bit of power, you might want to set it up as a pop3 account and set it to check emails every so often instead of getting them as soon as they come in.But I have amde it a habit to always use my charger whenever I am able to as these batteries seem to be happiest when topped off whenever possible.
Hello again, I'm still experiencing this problem and it seems not normal.
Simply put, I fully charge the device. I turn it off. It discharges by itself with all wireless functions off.
Today I did a hard suspend (keeping off pressed) with battery at 60%... when I turn the unit on 7 hours later the battery was at 6% with a critical warning sign.
I'm NOT using the device, I turn it on, use WiFI for 3-5 minutes then switch it off and put the device to suspend. I turn it on after a couple of hours, play with the menus and turn it off again. Just by doing that the battery drains by 10% every 5 hours or so, sometimes it won't even turn on due to battery drainage.
Is this NORMAL? I need to know if my unit or my battery is defective so I can return it to the seller in time...
Thanks, best regards
Sebastian
Battery life DOES seem to improve with time. The first day my battery wouldn't last for 5 hours! Keep charging your battery and letting it drain as much as you can (whether or not to let it fully drain is debatable), and I bet you'll see some guaranteed performance.
Also, what would help a lot is if you found and installed the Today plugin BatteryStatus and checked the "Show More indicators" option, and see what your battery drain was. The normal is between 150mA and 300mA when you're on the Today screen. Any more than that, and you most likely have a problem, assuming connections besides phone are off.
sounds normal to me, turning off you mean by pressing the button on the right side of unit? if so, mine is the same way
I'd say that was definitely not normal performance. On average, I use mine for at least an hour worth of talk time, an hour or two running TomTom, numerous SMSs, and at least a couple of hours reading books. I charge it every night, and the battery is generally running at around 50 to 60% by that time. I'm surprised at how quickly yours is draining.
I have an RX3715 inhabiting a drawer, and, while the battery life was a lot longer on that device, the battery was a lot larger, and the screen lower quality. The fact that it is not connected to a mobile network gives the battery a much longer life too. When I used it purely for TomTom, connecting to a bluetooth receiver, the battery faded very fast.
I've had a Kaiser since day one. I have found that adding a comm manager that allows forcing the phone to Edge give huge battery savings. In standby with the phone radio On and BT radio ON, WiFi OFF, my phone drops 4% over night very consistant. On Edge battery lasts days.
The only time I get fairly high battery consumption is streaming with 3G. Edge is so much more efficient on the battery, so if you don't need the speed, throttle down!
The only time I've ever found the phone Dead or close to dead after only a few hours on standby was when I had WiFi ON and the phone in standby. I can't pinpoint what exactly causes the condition, but when it occurs, the phone is HOT and the battery heavily drained in a short time. This has happened with both Hermes and Kaiser. I never leave WiFi ON when not needed, and have never seen severe battery drain since.
I do sometimes turn off all radios except WiFi, and then use wired ear buds and stream Slingbox video to the phone over my home WiFi LAN. I can get almost 4 hours of watching on a charge.
The battery should not be draining when powered off, but not much at all when put in sleep mode. Get yourself a replacement Testing.
As an aside, Alex's WM 6.1 BETA 2 has given me the best battery life of any rom. Only about 25% of the battery drains per day. With most other roms it's 50-100% per day.
Hello, thanks to everyone for your replies. It's strange because I've been doing lots of test, switching batteries (I have 4 units to test now) and I get inconsistent results... the 2 most problematic units were bought from the same eBay seller and got their ROMs changed the first day, the 3rd unit still has the AT&T ROM and was apparently not draining as fast. The problem is that the 2 first units seem to get battery drains overnight in flight mode of 10% and 2 times one of them got a 0% critical battery status just by being in standby and not in use (none of them are working as phones and have the function off)
The odd part is that for some reason this happens only sometimes, now I've switched to Sleuth's WM6.1 ROM and the problem is gone for now, I'm still at 90% since 2 nights ago having turned on GPS and WIFI for 5 minutes each 2-3 times... the other 2 units have been in standby from 100% charge and they haven't dropped either! And they're using the AT&T ROM and Q-Mobile v1.2 respectively... what kills me is that I cannot say what's wrong, cause I've swapped batteries, swapped chargers, swapped ROMs but cannot trace which is the problem (or if there's a problem at all)...
Perhaps it's normal for the unit to sometimes drain 10% after 8 hours of standby in flight mode and on other times remain at 90% for 2-3 days if not in use...
Thanks everyone for the read, I'd appreciate any comments
Regards
Sebastian
What radios are u using. Try changing radios
10% loss overnight in standby would be normal.
Does the unit get warm when you notice rapid drain?
I wonder about the "old" active sync problem - does the device show any running programs when you turn on?
In general you should expect to get a days worth of power using it for the odd call, perhaps an hour of wifi and perhaps an hour of prgram use. Of course all taht is very variable but I generally get away with a charge once a day. Occasionally, I take it from it's holder and it's warm to touch, but usually it's 'cos I've forgotten and left something like tomtom running.

when i got this diamond phone last week the battery performance
was bad serving me with less then a day worth of power where i
had to buy a second battery.
now that i have been off from work for a few days (3 days) i finaly
had the chance to cain this phone properly eg. flipping wifi on/off
through out the day listening to shoutcast, lenghty periods trying
to setup LAN, listening music while out on the road and checking
emails, looking on the net, yapping on the phone and sending txt messages.
to my supprise the battery seem to be holding up pretty good. now it
appears to be holding out till the end of the day where before i had to
carry two batteries now i think i can get away with carrying just one.
here are my stupid questions
1, does htc batteries get better performance after multiple charges?
2, did i have a semi faulty battery and now a miracle has happend?
3, am i just dreaming that the more i use the longer the battery stays on?
today i charged the bat. at 9am (ish) and now its 3,45pm. i still have 3 bars
remaining im supprised as from before a few days ago this was not the case.
im using the daimond with no mods and standard battery.

suprised!

hiya mate,
I am going through the same thing. First day I got the phone and battery was awful about 4 hours it lasted me! very shocked. but it is holding out.
I did charge the phone initially for about 12 hours as specified but don't know if that helps.
what i tend to find with new mobiles is that you have to charge fully and then DISCHARGE FULLY the phone numerous amount of times to get it to perform to the best of its abilities. I don't think its anything to do with HTC batteries, just the fact that new batteries have never been used and need to learn!

you are half right. this battery life is improving if you keep charging it but it is not advised to fully discharge them.
the fully charged-fully discharged method was for the old batteries with "memory".
somewhere in this forum, in the trinity forum somebody experimented the two ways of charging-discharging the battery. the conclusion was that it is better to charge the battery anytime, any occasion u have.
Indeed, the battery's performances (and this is applicable to all common batteries) will increase by time until it reaches its max capabilities.
To gain performance, the battery has to discharge and charge very frequently, or better, continuously. I don't really know how the Diamond manages it (meaning if the battery is full, will the device still get power from the battery if it is plugged on, or will it drain power from the cable. It could also drain from battery if it is fully charged and charge it in the same time, or it could simply always take it from the cable and charge the battery in less time)
The reverse is also true, meaning if you don't discharge/charge your battery frequently enough, its performances will decrease by time.
Also, if your battery discharges and charges all the time, it's lifetime will be longer than a battery that is only used once in a week.
I don't know if I made it clear, lol.
By the way, don't think that if you keep charging your battery you will end up with weeks of battery, there is a limit and it is 850mAh on the stock battery, if I remember correctly.
thanks for the tips some say discharging is good and some say dont.
all i know its 8:35pm and i have only used 1 bar from around 4:30
which now leave me with 2 bars. im jumping for joy because normally
by 6pm ish the battery would have already died.
with all the hammering today i cant believe it only took 2 bars in nearly
12 hours and thats with no extra charge from the psu and only 5 usb
connections to the pc to sync and add files totaling 2 - 5 minutes
on each connection.
now i can officially say this phone is "DA BOMB"
time to sell the e90 and e65
The thing that kills the battery on this phone above everything else is the GPS - knocks it out in 90minutes or less. If you were having fun (even for a few minutes) with it in your first few days, this might explain it...
GPS?

yeha that would explain it but the thing is I haven't even installed TomTom or any other GPS related app!!! weird. but i've had it for about 4 days now and battery does seem to improve slightly on a daily basis.
Come on then... So we all know as to some people this will make or break selecting a rom..
Can you list your usage (lots of calls, internet, text etc) and how long the battery lasts for the roms.
If possible, can we list versions so we know the best for most recent version.
Battert drain is waaaaaaay to subjective in my opinion. Even after hard-resetting the same ROM the usage seems a little different sometimes. It also depends on the used radio version.
Usage Testing Idea
I agree that its very subjective.
But if there is someone out there with a spare Blackstone, and LOADS of spare time. They could write some scripts (Mort scrips? Not sure how they work.) that would just run on the spare phone and do 'stuff' to emulate usage. You could compare that to the 'no use' battery usage.
This is somewhat unrealistic though, since you would have to write a bunch of scripts. You would have to test the average battery drainage rate for each; WiFi, Data(3G, GPRS), Bluetooth, Just plain fooling around, ...etc. And this would have to be done for each ROM/Radio Combination... The scripts would have to run without interruption to guarantee accuracy. Then write a small equation you could drop your usage times into, to see how long the battery would last you. Or you could just rate each ROM/Radio Combo with a scale, to make it easier to read/understand. I would guess it would be limited (initially) to the top 5 ROMs and top 2 Radios, to save time. After that each Cooker could test his/her own ROM near release time, and just add the results to the list. That would drop the accuracy though using different phones.
You would just have to find a nice individual willing to spend weeks starting this project. (or multiple people, one to write scripts, one person to test each ROM/Radio Combo, one to take the results and do the calculations) Blah, Blah... I just saw this thread, and realized everyone asks this question and this 'scientific' approach just came to mind.
Ok...I am done... ;-)
Well compared t stock ROM, same usage i'd say Custom Rom's are ~30% hungrier i.e i get a day less of charge.
It's hard to say how long the battery use, all base on how to use, if only standby, all cooked ROM no much different.
http://www.gsmarena.com/htc_touch_hd-2525.php
Battery Standard battery, Li-Ion 1350 mAh
Stand-by Up to 450 h
Talk time Up to 6 h 30 min
I'm getting expected battery life with most ROMs, the battery becomes depleted after 6.5-7.5 hours of mixed usage (some phone calls, some wi-fi, some GPS, some music, browsing, reading) with consumption at 150-180 mah on average. Usually that spans across 2 to 5 days, so as you can see my device is in standby often and consumes little power then.
You can use http://ae.inc.ru/uptime.php to measure the uptime of your device. If the battery level drops down to <10% in less than 6 hours of uptime, then either you are hammering your device with wi-fi constantly on, high backlight intensity or your device fails to enter power saving mode while in standby. The latter could be caused by the ROM or the software you have installed.
Okay, a little back story. I've been a BB user for quite some time now, got bored and made the switch to N1 this past January.
At this point I'm ready to say: The N1 power consumption or battery BLOWS CHUNKS. But folks thats my take.
I mean here I am with the most powerful and best phone in the world right now and I have to keep my brightness at 33% (GOD forbid I forget and keep it at 100%, I wont make it through the day!). I have to keep my GPS off (so my geo tagging is always off by a few thousand freaking meters). I have to limit my use and take it easy on data intensive apps. It's ludicrous, I want to use this damn thing.
Don't get me wrong I'm fine with the 33% brightness and with the light use (because I'm a student and quite frankly I don't really push the phone like that, due to being in class). But I would still like it if the phone wasn't CRYING for the "milk" bottle every day sharply/promptly at 8 pm.
So the phone makes it through the day (hurrah). But it still annoys me that now I have this new "nag": "get home and charge me Ori". So if anything spontaneous pops up like say: a date with a nice young lady, you can bet your bottom dollar my phone won't be making it alive that night. It's another constraint on an already constrained enough life.
My buddy says "dude I don't know whats wrong with your idiot self.. blah blah blah.. my Nexus battery is great". But the damn jerk is coming from a G1 !!! go figure LOL...
When evaluating something you don't compare it to a pitiful performance. You see how you stack up against the best. So if you reached your conclusion because you are comparing it to a G1 or Cliq I have to honestly disagree with your method of reaching that conclusion.
PS. I'm not a nagging *****. I know I came off a BB. Thats why I'm not asking for much. I would just like to see the phone consistently make it to 11 PM every night from a 7AM 100% charge. Is that too much to ask for?
my battery never dips below 50%... of course i'm working most of the day instead of playing with my phone.
Seems about the same as my Nokia N95's was to be honest.
try the undervolted kernel, it saves you quite a bit of juice.
ill toss my input in on this after i run the att one for a few days to see how much running strictly on 2g actually saves, the tmo band one i had last a good 12-14 hours if i was playing with it mildly at work. thats with the check mark for 2g only, wireless is usually constantly on, and gps always on(but not always running up in the status bar), brightness set to auto
Not sure if there's whole lot you can do if you want to keep brightness at 100% and GPS chip on all the time.
I hike quite a bit and I use SportyPal to track my progress. Obviously when I hike, the screen is off but GPS chip is always on. Although I never managed to completely drain the battery so far, I would say it will last around 7-8 hours. I do use SetCPU so that when battery reaches below 40%, clock goes way down to the minimum possible.
Other than getting an extended battery, not sure if there is a solution. 100% screen brightness and GPS really taxes batteries on all cell phones.
By the way, this is MUCH MUCH better than HTC Magic (which in turn was much better than HTC Diamond). I'm not sure how they did it since the battery capacity is the same, screen is larger, and CPU is faster. I am happy.
Battery is better than the last few HTC devices I've used and on par with the TP2 (all had similar features, large touch screen, Wifi, GPS, BT). So I would say it's about par for the course as far as I am concerned.
Try the 3200mah battery from Seido... you can run all day with wifi, gps, and bluetooth plus have screen at 100% and still have 50%+ battery at 8pm.
If battery life is more important than the slim look, get the sedio 3200mAh battery.
With 0% brightness, occasional use (GMail, GVoice, GTalk), GPS and Sync on, about 20 minutes of talking, meebo IM running... The battery just lasts 12 hours. CPU profile set to 512MHz when below 50% battery; and is fixed at 245MHz when in standby/sleep.
For the amount of things that it can do I'm happy with the battery life.
If I'm going out I carry the AC cable in my coat pocket
I realize this may not be the best solution for most of you, but I also have a portable Duracell charger. It normally acts as a charger for 4 AA batteries. But I can plug-in a USB cable on the charger and the other end to N1. It gives me roughly another 2000mah worth of juice using 4 Eneloops. The charger is bulky though so no good if you want to carry them in pockets. But works for me when I carry a backpack with me. I needed this charger anyways for AA batteries so it's a nice bonus that it can provide some mobile juice for N1.
My battery life is pretty great. I'm running the latest Cyan with the EPE54B radio, i keep the screen on about 75% brightness and never change it, I leave wifi and gps on always, I have bluetooth on and connected for about 2 hours a day, for the 8 hours I'm at work I don't use my phone much only to send some txts and maybe use a couple apps. So I unplug my phone at 7am and when I leave work at 5pm I have 82% battery left everyday with my normal usage.
Just for reference; before switching to Cyan and the latest radio i would have 75% battery when I left work.
What are you people doing with your phones that you have to carry a charger or a spare battery with you?!
I'm coming from a HD2 and I easily get better battery life than half you guys even with heavy streaming radio/youtube usage and that thing has an enormous power-sucking screen!
zombie..
Thread revival time !!!
OK so I discovered a few things that are worthy of mentioning since I last posted this issue.
My Nexus off/wake button crapped out and I sent it back for repair. When I got it back it was wiped (like new). I forgot to setup my facebook app and widget. For about 2 days I was going around with the facebook app "off" (it was finals week as such I was not paying much attention to facebook or distractions). I noticed better battery performance. Eventually I set it up but my "Sync Contacts" setting is set to "Don't Sync".
Also I got the SMODA widget that gives u direct "on-off" 3G capability. So whenever I'm at around 30% battery life I throttle the connection to squeeze out as much life as I can. Unless I'm browsing and I need 3G.
Good day to you all and enjoy the world cup.
In all honesty, I've been getting the best battery life I've ever had with Froyo. I only charge my phone in the car with the car dock to and from work (25 minute commute) and occassionally let it sit on the desk dock when I'm messing around online. With those charging habits, I typically get two days of use out of it and have no issues doing any of the things I need to do with it without a charger (games, navigation, calls, texts, web+market browsing, etc.). I could not say the same about any of the Cyanogen ROM's I was running before.
Hope that helps.
I have to admit...I am a bit bummed about the battery life. I have the stocked 2.1, on the ATT N1. I have turned off the brightness and I can get 3/4 of the day on the battery. I thought it would last all day but I definitely have to charge it by end of day.
I am looking forward to Froyo for, by all accounts, the battery life has been improved.
Again, I should emphasize that "I'm a BIT bummed" for all in all...I'm still loving my N1 and haven't looked back.
I've got Froyo on mine and this is what I've noticed.
If I turn my phone on, and send about 10 text messages in an hour, then turn it off, my battery life will be around: 94%.
If I let it idle for an hour without any action, my battery will drain about 1%/hr.
If I am using the internet and sms and just constantly using the processor on the phone, in abour an hr I'll be at 85% battery.
This is all with the backlight set at 11% (lowest setting it will go)
my battery last 27 hours on reg use... 17 hours on heavey use...
Pauls Froyo
3200 Bat
GPS always on
Brightness Auto
Listening to music alot on it to.
I find that on the ATT nexus one, setting to gsm auto (prl) makes a tremendous difference for idle time. With this setting I lost only 11 % in 12 hours of idle. And when I unplug, after 1 hour my battery will still be at 100% with no use.
This setting still gives you 3g too, so no worries.
My N1 on froyo started to hog alot of juice. I don't know why, it was fine the first 2 weeks but after that it started to suck up loads for some reason. Got tired of trying new kernels and i did many options so i gave up and went back to Cyanogen.. Running 5.0.8 Test5 with Froyo Kernel and it's about 20-24 hours since i last hooked it off the charger and it's at 56% left. Amazing. Tho' im a light user and i keep most stuff off when i don't use it. Even 3G.
I think that our perception of what we should get concerning battery life is a bit skewed. If I have RIM device (last was BB on metroPCS) I can go like two days without charing. All my email is push. There is no Facebook widget, or weather widget, etc constantly updating. The screen is half the size with weak resolution. The processor is half the speed, or less. The ram is barely enough to run the device. I could go on and on.
The fact is you have a computer, a small computer you can carry in your pocket. This machine is about as powerful as a desktop was 2 years ago. You are powering it with battery that is 1500mh and is the size of a dollar bill folded in half. What do you want exactly?
If you want a battery that lasts 2 or three days, get a dumb phone. If want a pocked PC, you are going to have to deal with the fact that doing all of the things your phone does uses battery power.
If I unplug my laptop I get 2hours and 15minutes. My phone lasts about 7-8hours. I stream music an hour or two, text, play some games, browse the web. I know that it is going to die. I have a spare battery. I change it if I can't charge it.
Battery life is worse than a Blackberry and better than iPhone, and you get the fastest device on the market. What more could you ask for?
