newbie question about android - Nexus One Q&A, Help & Troubleshooting

i just got my nexus, digged around, updated to cyanogen, rooted.
i have a problem that on my old touch hd i didnt have:
the data connection is always on?? doesnt android know to close it when not in use so it will save battery charge?
thank you

on the nexus one it works a little different, it shows the 3G icon but that does not necessarily mean its doing anything. only when you see the two up/down arrows lighting up and flashing is there 3G data activity going on.

i guessed that, but, it keeps the data connection open? even without transfer it still uses power, doesn't it?

it is always connected in a way, all it does is ping the cell tower every 10 minutes to have an established point on reference. this by its self does not draw to much from the battery as you would expect, only when data is requested does the radio kick in to full power, so no worries that it will drain your battery. The thing that will kill your battery the fastest is that beautiful screen. try to bump it to 60% thats i nice brightness but yet saves on battery. also keep in mind the battery needs to go through 2 or 3 battery charge cycles for you to get the most out of your battery life.
average real world battery life should get you about a day and a half of bettery.

This is how all modern smartphones work nowadays. They all keep the connections "on" 100% of the time.
It's funny because I asked this question a few years ago
The answer I got was that it actually uses MORE battery to turn the connection on and off all the time manually, than to just let it sit idle.
Also, the N1 is useless without a data connection

i see. then ill just let it open and search for an app that will tell me which app uses the most bandwidth. i only found some that tell me the total usage, not by application...

What has the greatest effect on battery life?

Hi all, searched and couldn't find what I was exactly looking for.
when i first got the phone, the battery life was short but since a couple of weeks ago, it's gotten much, much worse. i've had the phone for maybe a month or so.
i'm talking about the battery draining 10% in 30-40 minutes on standby with nothing like bluetooth or wifi on. at least the phone used to hold a charge decently if it was on standby, now it drains like i'm using it even on standby.
what are the greatest factors that affect battery life? when i first got the rom i have now, it wasn't this bad so i don't think it's the rom itself. plus i absolutely hate changing roms (it takes hours to get all my settings back)
some things i thought of:
i could use g-light but i noticed this makes my memory use quite higher and this doesn't do anything for when it's on standby anyway.
how often the accelerometer checks for rotation, right now it was at every 200 millisecond. I've changed it to 750 now, i'll see what effect this has.
same thing for light sensor. right now it's at 500 ms now.
radio. but again it was fine at first with this 1.09.25.23 radio.
anything else?
With my original 900 mAh battery the consumption was about 15% every hour. This was with the data connection always on. Without this on, it would last 2 days at least.
I also loose quite a bit of power when I'm in a bad phone reception area.
But not knowing where the battery consumption is being used up can be very annoying.
Whenever I'm abroad (and thus have all data connections disabled with NODATA) I always get a massive boost to battery life so it could be some process sending/receiving loads of data that you're unaware of? To test that you could install NODATA and kill all the data connections temporarily to see if that helps? Not that that would narrow down what was happening completely but it might help point you in the right direction.
i also suspect it might have something to do with data. what i've noticed is that my emails don't download fully, only the titles download and i think it stays connected while it's 'stuck' trying to download the rest of the messages, i notice this because it says in the menu 'stop send/receive' meaning it's still trying to send/receive. normally, i have it set to check every half hour. but i guess now it's always connected to data... anyone know why it's doing this? (maybe i need to start a new thread as i can't find an answer for this email send/receive problem by searching...)
kill the 3G chip that works for me but be sure the the provider has a GSM network
yup, 3g is turned off. these days the usage is more like 5% used up every hour in standby with email checked every 30 minutes. i guess that's acceptable...

[Q] Maximizing battery life as much as possible?

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.

HD7 on Wifi - Is it really draining battery?

I know this was an issue an issue in the past for older phones. With the recent high tech phone/smartphones/battery, I am just wondering if this is still an issue today.
The reason I am asking, I experimented and let my HD7 stand still without using it with the wi-fi on then and wi-fi off for almost a day for both and appears that I have the same battery remaining. I wish I could see the percentage use but looking at the icon itself appears the same to me.
Any other thoughts?
So, a pretty nifty thing about this phone/OS, is when the screen turns off, it automatically kills the WiFi. When you turn it back on, it connects again.
This is how they're able to conserve battery life. The only downside, is if you were downloading say a big game, via WiFi, and the screen times out, WiFi dies and so does your download unfortunately. I was able to get the download to resume once, but usually not.

i think wifi doesnt consume any battery at all when its "just connected", only when a upload or download is going on , you might find the difference...

No, you are wrong. Even stay disconnect, the Wifi Module will keep searching for the new wifi spot and it kills the battery a lot. Than why i usually switch my Wifi Off (both my HD7 and my old HD2) when i am not going to use it
For the first time with a smartphone I've been leaving the Wifi on all the time, since it doesnt seem to really impact the battery that much. I'd only turn it off if I know I'm going to be a day or two out of Wifi coverage, just to save me having to grab a charger.
With my TD2, having Wifi on all the time not only shagged the battery but also slowed down the UI and made the phone hot as hell.
With Android I would have to keep my Wifi off because it would kill my battery but on my HD7 I leave my Wifi AND bluetooth on all day and I still get pretty good battery life. I only charge once at the end of the day.
the wireless radios, bluetooth & wifi, are so much more polished and refined as compared to the those in WM5/6. With WM, used to flash new radios posted on xda to acheive better reception/power consumption performance. WP7 does it right out of the box...
btw, you can set 'notify when new networks found' to off. If not needed by you, probably save some juice.

I believe the only thing that changes is that it doesn't tell you when it finds new networks, but it's still always on and searching. So it shouldn't make much of a battery difference on or off.
That being said, this is the first phone where I have left Wi-Fi on at all times and I get awesome battery life. Actually, my battery period has just been great. No complaints about how long the phone lasts. Much more than any Android or Windows Mobile phones I've used in the past.

[HOT!]Charging problems, false drain readings, dialer issue, battery life, SOLUTION

Hey guys,
I would like to make your situation easier, so you don't have to read like 1000s of forum threads to get information I'm giving you here. These are the issues I faced with my incredible s, and the so called solutions.
The device:
Stock EU htc incredible s/ htc droid incredible 2 on Gingerbread. NO software mods at all.
According to my knowledge the same applies to the htc desire s and the htc desire hd as well. Most of these problems come forward after updating to gingerbread. If you are still on froyo, I wouldn' recommend updating.
1st issue. High standby drain.
According to Currentwidget and battery monitor my incredible s doesn't have lower battery consumption in standby than 38Mah.
Solution:
Drain readings are corrupted, there is a bug involved.
In reality You only have around 5-6Mah drain in standby.
Proof.
Left phone in standby for 2 days without messing with it, ended up with 40% left.
So if you have a minimum of 40Mah drain for two days. (48hours x40Ma=1920Ma) The battery's capacity is no more than 1500Ma, so it's obvious that standby drain readings are corrupted.
IGNORE drain readings!
2nd issue: You take it off the charger and it's 95%
Some say that phone charges till 100% than shuts charging down till battery reaches 90%, than charging starts again.
Some say our Lithium battery cannot get charged till 100% which is normal. This is the reason our device doesn't show % in notification area.
Solution: Ignore battery monitor, use inbuilt battery charge indicator, and be happy.
If you want to test battery life, start test at 90% and your test won't be corrupted.
3rd issue: Dialer using too much battery.
This might to be a bug as well. Still to be confirmed. The dialer doesn't use that much of power it only gets stuck in built in battery use indicator giving false drain data.
Some say it doesn't stop using proximity sensor after being in a call, hence the big drain. Incredible s's proximity sensor is visible during call, check it in the dark, it blinks. After call it stays inactive. So the dialer using it 24/7 seems to be a false statement.
4th issue: Declining calls in pocket.
When taking or declining a call, you swipe vertically on the screen. If you have your phone in your pocket with the screen facing your body, you can easily take or decline some calls when pulling out. This is more likely if you have a pocket made of thin material.
Solution: Put your phone in your pocket with the battery cover facing your leg. Don't worry about bumping into like a table corner and smashing your screen. Our gorilla glass is almost indestructible. Using a pouch or cover does the trick as well.
Not sure why htc is so obsessed with the vertical answer procedure. With horizontal swipe we wouldn't have this problem and users have been complaining about this since the desire came out.
5th Issue: Wifi disconnects when signal low, but still would be fine under froyo.
Connection gets disconnected when signal is 86db or lower.
This is a gingerbread related problem, htc cannot do anything about it.
No solution just yet.
For those who complain about battery life, I am on gingerbread with loads of apps installed and with very heavy use 3hours of display, wifi, skype,internet browsing I can use the phone for 12 hours. With moderate use min 2 days.
Battery saving tipps:
-Don't let google and htc sync. It uses lot of data and battery resources.(I don't like my sensitive data to be copied on their servers anyway.) Sync with your pc regularly.
- If u use data for e-mail and weather sync, use Gsm only mode, you don't need that much of speed for those, turn WCDMA on if u need it for skype, etc. Hspda and 3g are big battery killers.
-Everything on manual sync. There is a sync all widget in sense to use. U can hit it anytime you want to.
-No live wallpaper
-Hotspot uses excessive amount of battery. Use it on charger only.
-Screen light to be turned down. Use Screen filter app nighttime.
-Turn wifi and mobile data off when not in use, so phone can sleep properly. (wifi timeout app)
-Turn off wireless network positioning.
-Keep bluetooth off when not in use.
-Select short screen timeout like 15s.
-Screen on time is the main culprit in appalling battery life. Use your watch to check time rather than turning the screen on.
-If u struggle to find 3g or Hspda for data or network itself, change provider, because no matter what phone u have, u will have this problem. Try to find spots in your flat with better signal for data. Searching for network uses a lot of battery.
-Try to charge your phone from 0% overnight with the phone off for a couple of times (8-12hrs)
-When gps is on it doesn't mean that it uses battery. If you see the sattelite icon blinking or just on, that's when it uses battery, a significant amount of battery.
-Consider buying the official extended battery available in US (droid incredible 2 2100Mah), coming to EU soon. I wouldn't recommend buying the unofficial ones just now.
Obviously if you apply some of these battery life will be better. If you apply all of them, battery life will be exceptional.
Hope I helped.
Have fun guys!
Hi!
Thanks you for this! I buy my incredible s a couple of days ago, upgraded instantley. I met most of these problems and now I am happyer with my phone knowing these.
Could you give link to the battery you wrote about???
i appreciate what you're trying to do - but if you are going to follow all those steps you might as well have bought a nokia 3210
"Use your watch to check time rather than turning the screen on"
i mean.... really??
As I said, you don't have to follow all the steps.
You might face conditions when you need every drop of your juice, so it's good to know how to get the most out of your battery, isn't it?

It's for the droid incredible 2, but thats equivalent to Incredible s.
Sorry if this seems sarcastic, but if you're gonna buy a smartphone and turn everything that makes it a smartphone off, then save yourself a few hundred quid and buy a Nokia 1100
I use mine to sync everything and anything I want, and don't worry about it, as long as it lasts the day, which it does, I'm happy.

you misinterpreted what the op said. He is just stating what you could do if you found yourself in a situation where you had to maximize battery usage. Obviously most of us are around an outlet or usb plug most of the day so that we can charge the phone often.
Thanks for the info OP. I just wish that current widget would show us the right info. Or some other app :/
Thanks for the info OP. My buddy has had endless problems with his Incredible. I'll Chrome to Phone this thread and send it to him!

Its not the apps fault, the phone just reports wrong. So any other app should also fail.
@superman, perhaps a faulty app is causing the problems
Wifi issue should be resolved with the ota update.
However there is a network at my workplace which I couldn't connect to. I guess it is some kind of wifi repeater, it doesn't look like an actual wifi router. There is no cable connecting to it. Apparently I can connect but I get 0 signal next to it. Others can connect with full signal. Any idea?

It is FAR from "almost" indestructible. Some people also say it's impossible to scratch it, yet mines been scratched (this AND nexus one) It's nice glass but indestructible? I think not, not even "almost"

Battery saving tipps:
-Don't let google and htc sync. It uses lot of data and battery resources.(I don't like my sensitive data to be copied on their servers anyway.) Sync with your pc regularly.
- If u use data for e-mail and weather sync, use Gsm only mode, you don't need that much of speed for those, turn WCDMA on if u need it for skype, etc. Hspda and 3g are big battery killers.
-No live wallpaper
Click to expand...
Click to collapse
Live wall papers do eat your battery, but it's almost close to nothing. I've read that whatever uses more than 2% of your battery will be displayed in the "battery usage" I've used live wallpapers and it's never even shown that. (I think it also depends on what kind of wallpapers you use though.. let's say you had one that interacted with you) perhaps that might drain more battery.. but who turns on their phone to play with their wallpaper lmao
I've tested and disabling google sync barely makes a diff. I also don't think it uses a lot of data. I don't completely disagree with you though, manual sync is probably a better idea. On the other hand, I don't really think Hspda/3g are big battery killers, I notice that if you use the browser, the battery drops quick. Let's say you used "gsm" / "2G" and the webpage takes longer to load whereas 3G would have it loaded within seconds.. Which would waste more battery? I'm not 100% sure but I'd say just keep 3G and turn on 2G if you're not doing anything else with your phone. To my surprise, 2G is horribly slow.

Completely false. This is only a cover on top of your screen. It doesn't change the power being outputted to the screen. If you look at what RogerProdacter is making, you'll see that he's trying to modify the phones brightness output.

-Select short screen timeout like 15s.

Disagree again. It's really up to user though, that's insane. I'd be pissed if my phone kept shutting off in 15s! What you can actually do is turn off the phone yourself or get something like Lock screen widget which instantly turns off your screen. Two reasons it's better - You don't have to worry about the timeout - you shut it off sooner than 15s.

that's crazy.. You're saying that for us to check battery life/uptime we should use our watches? That's insane! That's a lot of effort to keep track JUST for your battery. Is it worth it? (I wouldn't think so.. but it's up to whoever uses it lol..)

I don't know what kind of world you live in, sounds way too good to be true. Just instantly change providers eh? Where I live.. that's not really easy to do. I'm sure most people getting cell phones would have enough common sense to pick something that works in their area anyway.

Getting the most out of your battery

Ok going to try and start a conversation here to get feedback from everyone on what you guys do to get the most out of your battery. I see alot of people always asking what kernal is best for battery life and some people seem to have horrible battery life and some have exceptional battery life. I personally get decent battery life. Nothing super amazing but that comes down to the way I use my phone.
My current battery I'm using - Andida 2000mah battery
http://www.ebay.ca/itm/280843217453...X:IT&_trksid=p3984.m1497.l2649#ht_4497wt_1396
I also have - GTMax 3500mah battery
http://www.amazon.ca/GTMax-Extended-Battery-3500mAh-Microfiber/dp/B006VAP102/ref=pd_rhf_se_p_t_4
The Andida gives me generally a extra 2-3 hours more over the stock. I had to cycle the battery 4 times before I started seeing any real improvements. If I take these off the charger at 6:30am I can ussually make it to around 10pm without needing to charge.
The GTMax get me through a day (630am - midnight) with around 50% left.
Now keep in mind this is based on my usage habits, and when I'm at work my signal is horrible so it drains a bit harder for the 8 hours I'm at work.
I don't have LTE where I live or work, I do get LTE in areas close by but on a regular day I don't see it. With the bad signal at work I've started to switch to gsm only mode (phone was constantly switching from Edge to 3g/4g and wouldn't provide a stable connection most of the time). This seems to have helped my battery at work.
When I flash a new rom I always give it at least 2 good full battery cycles before judging the battery life on it.
Ok onto some apps. My first foray into getting better battery life started with wanting to control my data. I used Juice Defender to that but I found that having to wait for the data to turn back on was at some times taking way to long and even sometimes I would have to reboot to get it back. Tried a few others and had similar experiences. When it works its nice and I did see some gain from it but at the same time it seemed bloated and slow and I decided I like having my data on and readily available quickly. After some searching I found an awesome app...
Better Battery Stats

I highly recommend reading up on this app and trying it out. If your seeing a big drain on you battery while the screen is off, it's probably because there is something that is keeping it from going into a deep sleep mode. This won't save you any battery just by installing it but with a little work it can make a pretty good difference.
Ok now this is where I'm looking for suggestions, are there apps that you find specifically run smoother or are lighter than their stock counterparts or rival apps that put less of a strain on the battery?
Instead of the stock messaging app I run Pansi SMS. It gives me a few extra options but I never really used the stock mms on ICS so I can only compare it to Handcent SMS and I think it is definitely lighter and a lil bit more battery friendly. It's not a huge difference but I try and squeeze everything I can w/o giving up functionality.
For a launcher I'm running apex right now, but for a lightweight launcher I'd recommend FTL. Runs really nice and smooth, nothing fancy about it, just fast and light.
Some apps sometimes can just be poorly coded and thus have a bad effect on battery life. Alot of people seem to feel the Facebook app is one such app that suffers from that. The app that gets the most recommendations as a replacement and being a bit easier on the battery is Friendcaster. I tend to agree with that, and would recommend trying it out.
I'd really like to hear about what everyone else does to try and squeeze out the most of their battery. Theres more stuff that I do, such as reducing the amount of things that are synced to only the stuff I actually want, default settings just sync everything and I don't feel I need to sync my contacts on a daily basis as I rarely change them around. So share your tips, experiences good and bad with apps in regards to your battery, and if theres enough feedback I'll try and re-organize this into a bit better structure.
I personally always leave data off. WiFi is on a lot. I wrote this:http://forum.xda-developers.com/showthread.php?t=1631831
I am very please to get a day and a half with the extended battery. Generally I am always texting,also.

Right here, this is the key. I have data off all the time. I only turn it on when I need to look something up or browse. IMO auto updates really kill the battery and aren't worth leaving your data on all the time. I'm on wifi a lot as well. Currently I'm on DarkRaider and I'm ending the day with around 30-40%, great improvement over stock.
It seems that with every new handset that comes out this is one of the hottest topics but the parameters all always the same with regard to battery life.
The 3 biggest things that drain our batteries are Display Usage, Data Connection & Radio Cell Connection. These are listed in order of current used. Of the 3 we can have some control over the 1st 2. Lower screen brightness and disconnect data when not needed and use wifi when possible. While wifi does use a good amount of current it's not as much as mobile data. The last one, Radio Cell Connection, we have very little control over. It's also the reason we see people having great differences in battery life. The further the phone is from the tower it's connected to the more juice it needs to make a good connection. So other than leaving the phone in airplane mode or planning your life around where towers are, neither of which are very practical, there is not much we can do there.
To get the best all around life from Li-ion batteries do not fully discharge them very often and also don't keep them plugged in after they're fully charged. It's best to recharge them when they get down to 20-30% and unplug them after they're charged. They also don't need to be fully charged every time, they have no memory. If your on the go and can only leave it plugged in for a short period of time that's fine. Also if you have more than one battery and your not going to use the 2nd one for a while don't store it at full charge. drop it down to 50-60% before pulling it out.
I'll update this post when I get home tonight with more info and links. Hope it helps.

I always make sure my auto updates are off. WiFi isn't an option for me when I'm working. How do you manage your data connection? Do you manually turn it on and off or use an app? I never really tried manually turning the mobile data on/off, just found with apps like JD that it sometimes took way too long to establish a connection. I always shut off my wifi when I leave for work. I know with ICS the widget toggles for gps don't work, they take you to the settings to turn it off, is there one for mobile data?

With my 3500mah battery I don't really worry about turning anything off. That thing is great. Made a bumper case for it but I miss having a real case on it so I picked up the 2000mah andida battery so I could get a few more hours on some days. If someone ever made a real case for those big batteries i'd use it all the time.

Try 2x Battery from the store. It will shut off data as soon as the the phone sleeps, it reconnects at screen on after unlock almost instantly. It also allows you to white list apps, like Pandora. The free version only allows 1 app though.

The DarkRaider ROM I am using has a nice extended settings menu in the notification bar with a data toggle. I also have a nice widget from switchpro widgets where I can customize what kinds of things I want to be able to toggle from my homescreen. Currently I have data/wifi/vibrate-silent/gps. Doesn't take long at all when I toggle the data on/off, it's pretty much instant.

I use the 2X Battery app. When the phone goes to sleep, the app turns off the data radio. I can still get calls and text messages. I don't have a need for push notification of e-mail, etc., so this saves me some battery usage. Of course, if e-mail and other app notifications are important, this app will help only if you are willing to wait until you wake up the phone.
Here's what I do. I'm on the stock HTC battery.
I SetCPU screen off to 192/192 ondemand, in call to 810/192 ondemand, and regular use to 810/192 ondemand.
I listen to about 2 hours of music a day, have 3 GMail accounts on autosync, a Facebook account on hourly autosync and HTC Weather on hourly sync. Automatic brightness. Roughly 1.5 hours of cumulative web-browsing, no apps/games used.
I never use WiFi and I don't live in an LTE area.
I typically end the day (19-21 hours unplugged) with ~40% remaining.
Now I am not sure if living in area with LTE is a bless or curse....
I would unplug around 7am everyday, and by the time I get home (around 6pm) I would always in red mode (meaning, it is either 14% or under). Using the Holics-0.6 with the kernel that came with it, battery seems to die fast. Even when I am on the stock ICS before this, seems LTE would just bleed this baby to death....
Reading other comments, might as well start looking for a bigger battery....
It actually seems like I'm getting better battery since LTE came to my town. I'm on dark raider using kozmick's rc1 kernel and it's even better now. Try turning off vibration feedback...I think it's located in the sounds menu in settings. You can also try using automatic brightness or even just setting it to stay at 50% or lower. The screen is a battery hog. There's a stickied thread somewhere on here that has other things you can try too.

Really is a shame that we have to disable or ease everything back so much to get through the day on a battery. Anyhow, I have a Velocity (which comes out of the box with the processor running at 1500) on Dark Raider. Therefore I use SetCPU to throttle the beast back, depending upon the circumstances. It only is allowed to run at 1500 when on charge and down to 400 when battery below 25 percent. I also use 2X Battery to take care of the netowrk and Wi-Fi and have purchased the andida battery for extended life. I also have JD installed, however it is rarely used - reason is that I am in agreeance with "citsong" that it takes too long to establish connections, even causing me general connection issues from time to time. So for around $25 AUD you can get through the day on a battery with moderate use and reasonable performance. I have not tried the extended battery pack, though I will probably get one of those as well...not sure which are the best???
I personally don't like the vibrate response thing, so I turn that off right out of the box, also, auto brightness is another that I set. When I go in the battery tab to see what is bleeding it to death, and most of it would be the display....
Though, vivid seem to have a smaller battery compared to other phones of similar functions and/or size, so that might be the reason I am not really seeing a very good battery life?

Actually there are only a couple phones that have a larger battery...
The galaxy note and the atrix are the ones that come to mind...
And the note has a larger screen and Samsung's rediculious samoled screen which eats battery like potato chips...

My solution was to get a larger battery (2100mAh, the largest one with stock format) and using juice defender to control my Data Connection. I am getting about 60% more using time on a normal usage whan before!
I actually have both Motorola Atrix 2 and HTC Vivid. However, my Atrix 2 would last about two days between charges, which is kind of weird. I have my personal account and company account on that phone (personal is to activate the google stuff), so it eats up data twice as fast, yet it is almost twice as long battery life.
And to update a little bit from my post before, it seems I am getting better battery life now, after 4-5 days of flashing the new ROM, let's hope it is true....or I am just going to go hunt for a bigger battery

Actually, the Samsung Galaxy Note is way bigger than either Atrix or Vivid, so with a bigger body, I would assume that a bigger battery is possible. But if you look at current phones, I rarely see batteries that are above, say, 1800mAh, let alone 2000mAh and above, stock of course.

Could you share the details on the battery?
Andida batteies are easily found on Ebay, but beware of Chinese fakes!! I got mine from a seller in Canada, all good.
I get good battery life by turning off data while I'm working . 70% with 8hrs unplugged
