I decided to do a "best case scenario" test, and see if some of my battery issues were from apps gone awry, or some other drain. I pulled my phone off the charger right after it went green, and let it sit on the table. Wifi is off, BT is on, and I'm using my airave, so the signal is a full 6 bars all the time. I have 3 email accounts configured. Two of them are direct push, and one is an IMAP poll once every 15 minutes. Few, if any, emails were received during this test. The breakdown is like this:
4hrs, 32mins on battery. Battery currently at 92%
Cell Standby: 33%
Phone Idle: 32%
Display: 23% (the display was only on for about 30 seconds of the entire test)
Bluetooth: 4%
Maps: 4%
Android OS: 4%
So at least i know there isn't a process running that is making my battery next to useless. My battery seems to be getting slightly better with each day of use, but I still can't wait for the extended battery/cover to be released. I really got used to that on my Evo.

that sounds a lot better than my setup.
I went from a full charge to 50% with very light usage in 8hrs . I've been asleep for over 7 hours.
Display: 29%
Cell Standby: 27%
Phone Idle: 26%
Android OS: 7%
Voice calls: 5%
Maps: 5%
However, I have horrible reception in my house, even next to the windows. All's fine as soon as i step out the door.
I've found that a weak signal has a dramatic affect on battery life with these phones. They do so much syncing in the background, and it takes so much longer with a weak signal (not to mention it has to transmit at a higher power). The signal makes all the difference.
Call sprint and get yourself an airave! They gave me mine for free.

do you guys have the display setting on auto or low brightness. My display usage is always through the roog. I am getting decent battery life. I turn 4g off usually and just use 3g unless I am gonna watch youtube videos or sometihng.
I unplugged the phone at 7:15 this morning and I have email, facebook all syncing. wifi off and I am at 92%. So far this phone is being very good at battery life, specially after the first few cycles.

I have mine set at a number. I use a program to change my brightness at night.
7.5hrs & 70% battery left!!
Is it better to have the brightness automatic or a number like 30 percent?

I just use auto brightness, I had about 11 hours use and 80% remaining taking a bunch of pictures, a little navigation and texting. This is with wifi on about half the time.
My battery was crap for the first three days with the phone, after calibrating the battery and giving it a few cycles its been really good for me. I do top off the battery usually before I pull it off the charger for the day.
I have mine set to auto and I see it changes even as I'm typing this message. Truth be told, the battery does drain when we don't have good signal...

Auto brightness us worse for your battery. This is because it has to use sensors every set time interval to check the lighting. It's not a TERRIBLE drain, but over the course of 4-5 hours it would probably save you 5-6% if you set it something lower .
And to the other person who asked, your battery life is SIGNIFICANTLY lowered when you have poor signal. What happens is your phone's radio draws extra power when it has poor reception in order to boost its range/signal. For those of you who work in places with poor signal, I bet you can attest to this
Also, I have a few battery tips in my signature if you're interested in more. It's slightly outdated (as in there are more methods now), but everything in the article is still true

Fully charge your phone, then use it until the battery complete drops...Then charge it again
How many cycles have people run on their batteries? IE full to dead?
I have auto brightness, GPS on Bluetooth on, email sync every 3 hours, weather sync evey 3 live wallpapers, and I forget the rest. Battery lasts me 12-24 hours, which is about what I got with my Hero modded out with setcpu and etc. I like the battery life of this phone.

My phone died in about 6-7 hours of steady drain, then I calibrated by doing the same thing they told us to do with the OG evo.
Charge over 8 hours, turn off the phone charge another hour, turn the phone on charge another hour.
I top off by using the phone for a couple minutes, then putting it back on the charger until full. The phone clearly goes down to 95% from full while charging and back up, I like how on this phone you can see that it does it on the battery graph so you know.
I've had my phone off the charger for like 34 hours and I'm at around 48 percent battery remaining. Not heavy usage but not super light either.

69% as of now. I had to reboot today so I can't say this is average. I know there are issues that can't be fixed until root, but as a stock ROM, it seems the power management isn't half bad.

Sense has always been pretty good about power management (especially when you consider the puny batteries they put in their phones), and an asymmetric dual core processor definitely doesn't hurt haha
Just curious what everyone's overnight battery drain was using CM7. The lowest mine will go is 10% over about 8-10 hours of non use, only one gmail account syncing, nothing else. This is using every variation of CM7 (stable, nightlies, and weekly's)
Using the new 2.3.5 fruitcake I am get a consistent overnight drain of only 3%.
I have tried everything possible to match that, but I'm beginning to think it's not possible.
i only have facebook but log out when i go to bed yet my phone still drains at least 10 percent every hour haha
I'm loosing also between 8 and 10% of battery overnight. I tried to optimize it in anyway including reducing brightness, deactivate services etc but still the same result. This is something which I hate with CM7 previously I used SGS and I had the same problem there. I don't know if it is a general CM problem or just these two phones.
Strange

That's really weird. Ever since I've started using different versions of CM7 I've averaged 2-3% drain overnight. This was both on the stock kernel and faux's enhanced stock. Only thing I would do before bed is turn airplane mode on.
Lately, it's been 3-4% drain overnight but that's probably because I've been installing a lot of apps (Can't pass up those $0.10 deals). Even after switching to Clemsyn's 1.0GHz kernel I'm getting the same amount of drain. Have you guys tried flashing a new radio or setting up SetCPU profiles?
Attached pic is with a little over 2 hours screen time.

I imagine the op is not refering to stand-by in flight mode. Personally, if the phone is in flight mode sat at my side while I sleep then I might as well switch it off.
My battery drain is probably around 15% over 10 hours on Ba2tF, Faux enhanced stock. That is with 3G on and background data, including syncing gmail/contacts etc. It is certainly higher drain than I would like and was getting on stock Froyo.
However, I think ~2 days standby is not ridiculous - 1% per hour will get you over 4 days which I think sounds reasonable. We all fall foul of spending hours of our time trying to squeeze a bit more life out of our phones but most people reviewing them these days are quite understanding: "the battery life was OK - it got us through a day's use"...
Yes I agree but we have a great large battery and still can't get better life. Is it the CPU draining the battery so much? When I'm on 3G and using the phone actively during the day the battery last for no more than 10 hours. There should be a reason why the CM7 is draining the battery faster and this is what wir are trying to realize. If it was 10-15% more than ok but it is almost 50% more than a Stock ROM

I'd agree except I use my phone as my alarm clock , but point taken. Without airplane mode it would be 5% tops.

It seems that new build of GB gets pretty awesome battery life compared to most older builds or custom roms. I believe Nottach pointed this out when he initially started playing around with it for Darkside. If you haven't tried re-flashing your radio, I would definitely give that a shot. (should be in the OP of the CM7 thread)
I don't think that flashing new Radio will solve the problem. CM7 doesn't come with Radio anyway. Initially I though that the problem is in RIL but after suspending all the data transfer for a night without any change I'm not so convinced that this is the problem. Unfortunately the CM7 mail client is also not perfect and after removing it I'm getting slightly better battery life.
Just for the information.
I loose 3-4% per night (7-8h) in airplane mode.
Weekly 3, Clemsys 1.4 Elite version with a more aggressive memory timings, set at 1GHz and UV with SetCPU .
Good for me.
3-4% in Airplain mode is not an option. We are trying to figure out where is the leakage. I'm pretty sure that it is a common for all CM7 branches.
I lose 1 percent overnight with everything off. No wifi or data is on and nothing syncing in the background. I have never had a phone with such amazing battery life. Not even the old Nokia 3310 or Sony Ericsson K800i compare to this. I am pleasantly surprised.

Yea, battery is draining quicker compared to last Firmware. You can turn off WIFI during idle stage.. however, yea.. it's annoying.
yeah, i noticed this too. i even have wifi to shut off when sleeping and its still consuming 55% of the battery.
Maybe they boosted up the wifi signal strength a lot to compensate for the infamous poor wifi signal with battery drainage as a consequence.

http://forum.xda-developers.com/showthread.php?p=24228334#post24228334
Are you guys sure the stats are 100% accurate? I dont think that wifi actually sucks more juice than the display. Its the same on my Prime but its possible that the stats just arent that accurate. I have wifi set to disable when in sleep mode so i really dont think it makes sense that it takes up more than the display even in that setting.
Could be wrong though^^ My batterylife so far isnt really different than before the update - at least it doesnt feel different.
my battery life is still the same, which is great. wifi being a battery drainer is nothing new. top 2 battery drainers isbthe display(how high you have it) and wifi. I have my wifi on 24/7. never cut it off and I still get great battery life. I tried that cutting wifi off during sleep setting but I hate it. it always takes the wifi connection a little will to come back connected once display OS activated again. so I just leave it on. another thing to check also is to cut your background sync times down. you don't need email be checked and sync every 5 mins. cut sync off on anything you know you don't use much. saw goes for app notifications also. I got tired of my Facebook going off all the time, so I cut it off. it'll just update when I open the app up. or doing a manual refresh.
WiFi drain seems to be a lot higher since the update.
I got slightly over 5 hours of surfing and messing around undocked last night. WiFi used over 65% of the CPU.
Sure I was getting closer to 8 hours before.

I have noticed a huge difference. Last week my prime would only lose 2% battery over night. I updated and haven't changed any settings. Now it drops roughly 40% over night... I'm not happy to say the least. I'll try turning wifi off tonight and compare the 2 settings.
(By the way, I'm rooted and stock everything else)
Glad I am not the only one. I just got my TP a week ago and updated to .21 and sure notice that battery life has been awful. Using it for web browsing, loses 10% in about 40 minutes. And turned off seems to drain the battery as well, more than before the update.

I do not have drain over night.
I charged it full, and after 9 hours in stand by, battery was 99%
BUT the BlueTooth draines the battery when the Prime is in use.
The settings suggest to turn it off, if you do not need it.
21WW seems fine for me about the battery usage otherwise.
Do not expect the usage they were talking about in the specs.. it's not true!

WiFi analyzer shows no difference in signal strenght, and my Prime has been RMAed at ASUS and had changed parts (WIFI/BT issue), it did not help either.
Hey everyone,
I tried searching on here but couldn't find anything similar. I thought I'd post here as its battery related.
For a start, my Prime is completely stock with the .21 firmware. Earlier today I noticed my Prime battery monitor hadn't gone lower than 93% for AGES! When I went into Settings - Battery, it said 93% Unknown. I obviously guessed it was a lot lower than that as I had used it a fair bit most of the day. I was using it about 2 hours ago and it suddenly switched off. I guessed it had run flat so I put it on charge. I've just tried to switch it on and nothing!!! It's been charging for a good 2 hours or so.
Any ideas??? I've had it less than 2 weeks!!! :-(
Thanks in advance.

Sounds like your batterystats.bin file is corrupt. If you are rooted then navigate to /data/system/ and delete batterystats.bin
Reboot and Android will create a new version of this file and hopefully it will display stats correctly.

I am running .21 in power save mode. I have noticed the following. Using OS Monitor I found that "System" process was using 65%+ CPU resource all the time. So I turned off/stopped as many things that I could no effect..accept..un-mounting my SD card.
Once I un-mounted my SD card the "system" process time dropped to less than 10%.
Since then my battery has only dropped 7 points in 14 hours..based on my "Battery indicator" app.
So why would my SD card eat up battery life by consuming CPU time???
Hey guys, I am having a problem with my Amaze, more specifically, the battery is dying absolutely WAY to quickly. For example, yesterday morning, after unplugging my fully charged phone, I dropped it straight into my pocket, and maybe looked at it twice the entire day. When I pull it it at the end of the day, the battery is red, with 8% left. If I were to be using it, the battery would last about 30 minutes on a full charge, most likely. I've also noticed that the phone is really hot, even in my pocket. If it helps, I am on ICS and have been using it since it was leaked in April, however, this problem is new (about 2 days ago is when it first started), as I usually get about 8-10 hours with moderate usage. Can you guys please help me? Thanks!
Well if it just started happening recently, and you haven't made any changes, then the battery may just be going bad... If that's the case, you can call HTC and they will send you one free replacement.

could be just the battery.. but if you don't mind me asking - how long have you owned the device? I suggest you dl JuiceDefender from the playstore and see if that helps - Definitely helps my device get through the day with moderate use and one time charge every 1 1/4 a day but this could vary on owners usage. Also, check your settings to conserve battery life such as turning off wifi, gps, auto syncs on your fb, gmail etc. and adjust your brightness to the lowest if possible and OH... less widgets and windows > less power that the battery consumes. Hope that helps!

Nope, battery life isn't that great with this phone, depending on how much you use your phone and what all you use it for you will get any where from 6-14 hrs + or - some. Also your Rom and kernel will make a difference..

Nice!... Glad to hear
This happens to me from time to time, and the phone is ALWAYS hot when this happens.
What I've come to discover that it's usually something that' activating the phone while asleep.
The phone is hot, because the processor is being used. That's why the battery is completely dead so quickly, something is pulling it out of deep sleep and causing it to run full bore. The key sign is the phone is hot.
I recommend you get an app that lets you see wakelocks, and what's keeping the phone awake etc (I use GSAM battery monitor) Whenever I notice my phone becoming hot for no apparent reason, I know for a FACT that my battery will be dead in a matter of hours. Lately it has been "Android System" that's the culprit, and I can't quite nail down what is doing it, but it's very random and not much of a problem because I do a reboot and things are back to normal.
First, try to reboot your phone. Get system tuner and see what processes are using the processor when the phone is hot (make sure you show ALL processes, even the default excluded ones). Check the wakelocks. Get battery monitor and check the mA usage (it keeps a running history). When my phone is running optimally, I have a mA drain of around 70-90mA when screen off/deep sleep, and it should maintain this type of drain... when my phone is becoming hot for no reason, I see numbers anywhere from 300-600mA drain for no apparent reason. A lot of the time there was an APP that was offending, so I would first check that. Like I said though lately it has been "Android System" and it's kind of hard to nail that down, but it's so random.
When my phone is cool to the touch most of the time, I know it's running optimally because it's achieving deep sleep. I've found a lot of it has to do with what you had running before you turn the screen off. A reboot ALWAYS fixes it for me. If you can't seem to nail down the offending app, do a full reset back to stock and you should notice that your phone runs very very cool when the screen is off and it's sleeping. I usually get anywhere from 24hrs-2 days of moderate use with the screen off governor set to conservative, and maximum clock for screen off ~600mHZ. I use interactive governor for screen on, but that's for responsiveness and you'll probably have better luck with ondemand for battery life. YOu can set these in System Tuner.
Just remember, if the phone is HOT, it's using energy. If it's hot, something, somewhere, is causing the processor to run at a high clock frequency. If the phone is HOT after being in your pocket/screen off for a good amount of time, something is definitely wrong/rogue app. The phone should never be hot returning from deep sleep. I bet if you check your default battery monitor (The android one) you'll notice that the bar for AWAKE is probably almost solid blue, something is preventing it from going into deep sleep. If I notice my phone is hot when I take it out of my pocket, I immediately know that something isn't right. This should NOT happen.

I'm just past my 9th day of using my Amaze 4G.... so far, if I turn off data and turn off autosync, my drain per hour goes below 1%/hour... so i could get >50 hour idle battery life + 4 hours screen usage
with data on and autosync off, maybe 2%/hour -> this translates to ~ 20hour idle battery life + 4 hour screen usage
with data on and autosync on, maybe 4%/hour -> 10 hour idle battery + 4 hour screen usage
I have only calendar widget on my home page, only Google Accounts on auto-sync (2 mail account, 1 contact, 1 calendar)....

The phone is hot, because the processor is being used. That's why the battery is completely dead so quickly, something is pulling it out of deep sleep and causing it to run full bore. The key sign is the phone is hot.
I recommend you get an app that lets you see wakelocks, and what's keeping the phone awake etc (I use GSAM battery monitor) Whenever I notice my phone becoming hot for no apparent reason, I know for a FACT that my battery will be dead in a matter of hours. Lately it has been "Android System" that's the culprit, and I can't quite nail down what is doing it, but it's very random and not much of a problem because I do a reboot and things are back to normal.
First, try to reboot your phone. Get system tuner and see what processes are using the processor when the phone is hot (make sure you show ALL processes, even the default excluded ones). Check the wakelocks. Get battery monitor and check the mA usage (it keeps a running history). When my phone is running optimally, I have a mA drain of around 70-90mA when screen off/deep sleep, and it should maintain this type of drain... when my phone is becoming hot for no reason, I see numbers anywhere from 300-600mA drain for no apparent reason. A lot of the time there was an APP that was offending, so I would first check that. Like I said though lately it has been "Android System" and it's kind of hard to nail that down, but it's so random.
When my phone is cool to the touch most of the time, I know it's running optimally because it's achieving deep sleep. I've found a lot of it has to do with what you had running before you turn the screen off. A reboot ALWAYS fixes it for me. If you can't seem to nail down the offending app, do a full reset back to stock and you should notice that your phone runs very very cool when the screen is off and it's sleeping. I usually get anywhere from 24hrs-2 days of moderate use with the screen off governor set to conservative, and maximum clock for screen off ~600mHZ. I use interactive governor for screen on, but that's for responsiveness and you'll probably have better luck with ondemand for battery life. YOu can set these in System Tuner.
Just remember, if the phone is HOT, it's using energy. If it's hot, something, somewhere, is causing the processor to run at a high clock frequency. If the phone is HOT after being in your pocket/screen off for a good amount of time, something is definitely wrong/rogue app. The phone should never be hot returning from deep sleep. I bet if you check your default battery monitor (The android one) you'll notice that the bar for AWAKE is probably almost solid blue, something is preventing it from going into deep sleep. If I notice my phone is hot when I take it out of my pocket, I immediately know that something isn't right. This should NOT happen.

what program do you use to measure battery drain? I use Battery Monitor Widget, but it's not giving me an accurate answer (lets say I had the phone on idle w/o data/sync... the available % is stable over 5 hours (~1% loss per hour), but the current usage says at least -100mAh)
for me, the idle battery drain (apps autosyncing/using data) is the problem
I see my device properly going to sleep (deep sleep is the majority of the usage, not too many wakelocks/processes.....)
with data off and sync off, idle battery usage goes to a minimum

I'm just past my 9th day of using my Amaze 4G.... so far, if I turn off data and turn off autosync, my drain per hour goes below 1%/hour... so i could get >50 hour idle battery life + 4 hours screen usage
with data on and autosync off, maybe 2%/hour -> this translates to ~ 20hour idle battery life + 4 hour screen usage
with data on and autosync on, maybe 4%/hour -> 10 hour idle battery + 4 hour screen usage
I have only calendar widget on my home page, only Google Accounts on auto-sync (2 mail account, 1 contact, 1 calendar)....

I use battery monitor widget to measure drain.. as far as accuracy, I'm not sure? I don't know if it's EXACT but it seems to be a pretty good indicator of drain. When in deep sleep the phone usually measures anywhere from 70~mA-120mA. Usually it stays below 100. Before I changed the screen off governor / max freq (screen off) it was almost always 100+. Screen off governor is conservative with a max freq of ~600MHz.
I have no idea how exact it is, but when it's reporting ~300mA, my battery is definitely draining much faster.. and when it's reporting 500-900mA~ my battery is draining incredibly fast, so it at least seems to be a solid indicator of current usage.

On my previous phone (LG Optimus T / Optimus One/ P509, CM9 ICS ROM), Battery Monitor Widget reports more accurate readings (idle with data off= -2mA or -20mA<dont remember>, accurately representing that 1% of battery would last at least 2 hours)
Phone with the new kernel (KozmiK Ruby -0.5a) still goes battery drain crazy (even with Juice Defender installed now).... I hit 10%, then got fed up, turned off data... then the phone slowly sipped battery for the next 3 hours going down only 1%.... sigh
I think Facebook Messenger is the data hogger in my case, since I do use it often... will try a new ROM build without logging onto facebook messenger, see how it goes

What you said is true, at least for data on - autosync on. My battery last around 10 hours idle + 3.5 - 4 hours on screen usage. It seems that autosync eats a lot of battery. Will try to turn that monster off and see how much it will improve. I have bad habit to push refresh button on gmail/facebook widget, even with autosync on,
I used to get 14-16 hours. Now my battery won't last more than 6 hours. I gotta replace my Anker

Most recently I got 1 day and five hours with a fair amount of use by using faux 011 kernel and using CPU editor script to set it to battery saving profile. I'm at 45% right now with fairly heavy use after over 18 hours.
Battery life is totally under your control, it takes some work to get it where you want it.. but you also have the option of buying a bigger anker battery with external charger for $20 and carrying that spare battery, and simply not giving a damn.
Just saying, battery doesn't have to matter for a very small price and a little space to carry the spare battery in your pocket.

2 days? I had a full charge in this at 6 am, now i just got a 14% low battery alert at 2:28pm...
Is this normal? I am not doing anything unusual at all, did not use it to make a single phone call, and am at work so ive only checked it a handful of times today...
what have yall experienced here??? this seems ridiculous!
Well took my gear s off charge at 7:30am and have checked it at regular points through the day including showing it off to work people and it's not 22:37pm and I still have 67% left of the battery so mines about right...
I have thus set to do Gmail, Facebook, Instagram, sms, twitter and a few other notifications so gets used fully through the day.

hmm....
i just brought up the list of running apps and found that the music app was still open (though on pause) from this morning.
i have a hunch, playing or not, that if you leave the music app open in the background it may be the source of the battery drain.
no, i do not have the clock face set to always on as well. just music app running in the background on pause.
i'm hoping this is it, though since i killed tasks i went from 14% to 1% in as many minutes. I'm guessing not...
Took it off the charger this morning at 6:30am at 60% and as of right now at 5:30pm it has 33%.
27% in 12 hours

I cleared off my recent opened apps about 3 times during the day. that might have helped my battery
you may want to check out this thread (http://forum.xda-developers.com/gear-s/help/gear-s-battery-issues-t2935271)
100% @ 8:00am - 71% Now @ 7pm.
11 hrs = 29%. Used quite a bit.
I used it a fair amount today.
Took it off the charger at 7:10am (100%)
at 7:15pm it is 62%.
It seems to be getting better.
I turned off the Wifi. Maybe that has something to do with it?

Thanks for the link...
After i re-charge i'm going to try this:
Update on Battery Life for me
HUGE day of use primarily with notifications and texting. Up and fully charged at 7am and now at 5:30pm I'm still at 48% battery.
On Wifi
BT Tethered
Clock off
Brightness at 60%
Vibrate/no sound
GPS Off - which I think is a HUGE key to success. No need to have it on unless needed anyway.

how do you turn off gps? I do not see a specific option other then disabling the mobile network alltogether...?

TY! looks like it was already off though...
what does it mean:
Location - "gps only" ?
If it means to say location = gps, its a bit confusing...
additionally, the feature i disabled that so far has helped is the mute/pause motion option. This one option seems to be the culprit for my 100% - 0% in 8 hours issue. I'm never enabling that feature again! holy cow!
Just did my first full run down on the battery without charging, been running since yesterday morning and am down to 8%, so less than 48 hours so far, but still two full work days. I can at least forget to charge once in a while.
Not as good as my Neo's 4 dayss, but better than the 12 hours I was getting on the Moto.

Battery life for me is about a day and a half. I set the face to watch just to display black and white numbers I put a black background and that really helps. You don't need the full color watch background that drains a lot of battery when you decide to lift it up and down.

Update:
i disabled motion for mute/pause and the mobile network (i use bluetooth) and my watch now finishes at about 70% after a full day's use. VAST improvement!

Disabling Mobile network will improve battery life, i think. Check my post: http://forum.xda-developers.com/showpost.php?p=56722962&postcount=32
I get only 6 hrs from 100 to 0%.

gonna give that a try. this thing is getting crazy good battery life after its 6th full charge. after 13hrs yesterday with notifications, email reply's, multiple phone calls (two calls of 20 plus minutes) the damn thing had over 60% left. that's with GS to N2 via BT.
Battery life is getting better, been on for 14 hours and still at 75%
At work 13.5 hours and I'm at 51%. Turning off the wake up motion helped me today, and running tethered to my phone helped (although I will not keep doing that), biggest help was not running with gps (but this will not be a normal occurrence). I'm going to run with phone remotely connected and gps running tomorrow and see what just having the wake motion off will do for me.
6-7 hours on GSM
Most of the posts specify battery time while using it on BT thethering.
However I like to use it as a basic phone, no worrying about carrying everywhere regular phone.
Of course I have a phone in a bag (just for case, battery!, for emails, and browsing).
- So, when using it for regular talk it lasts from 9.am to 3p.m. Specifications:
a) about 1 hour talk
b) 2 sms
c) GPS Off, WIFI off, Move ON, not installing extra apps
d) BT and SONY SBH52 ON
This is not enough.
Charging is fast - (with no connecting to plug) i can get 50% batt in 30 minutes.
