I'm hitting 41 hours and still have 19% battery life. I noticed it took around 10 full charges before my phone started to get this great battery life. I've been using it as normal and even listened to howard stern for a couple of hours yesterday. Talked on the phone a bunch of times around 30 texts and even used my 4g for a few minutes. I've never had an andorid phone last this long for me even when I had my Optimus S which I thought was awesome.
Anyone else getting this awesome battery life? I'll post screen shots when its about dead as I dont want to plug the phone into usb to get the pics.
Charging twice a day here. Its worse than my hero.

I would investigate as that shouldnt be. My shift lasts almost 2.5x my hero. I bet if I had your phone in front of my I could find out whats killing it soo fast.
Is your phone getting hot? I would do a full system wipe and start over from scratch and see if it doesnt get better after you try the things I've listed below. Note, I didnt have this great of battery life until 6 days after I purchased the phone and charged and discharged numerous times. The first few days the battery life was not good at all.
A little list of things to do, check and or disable;
1. Use spare parts and find out whats killing your battery ie partial wake usage, cpu etc.
2. Turn your window animations from all to only some animations
3. Turn off automatic display and keep it around 20-30%
4. I have auto sync off on all my appz (E-mail, Gmail, Facebook etc.). I update my E-mail and such manually.
5. Turn off data when not using it. I find data accounts for around 15-25% of juice used and thats just when on idle.
6. Only use widgets on the homescreen if you really have to (Running widgets use a lot of power over time)
7. Use Android Hackers tool from the market and it will break down how long your cpu was in a certain state. ie my cpu spent 65% at 245mhz and 28% at 806mhz.
8. Keep off 4G, Bluetooth, wirless networks for location and GPS if not using it (GPS uses less power than wireless networks and is more accurate anyway) I assigned Quick Settings to open when I hold down the search button. That makes it easy to enable/disable any of these setting within seconds.
9. Turn off google talk and make sure it doesnt sign in automatically (most people dont realise this)
10. Turn screen timeout to 15 or 30 seconds (if longer your phone can keep the display on accidentally while in your pocket if a button is pressed, wasting power)
11. Dont use a task killer unless its to kill an app you know drains your battery and therefore must be closed to save juice
12. Check your apps. Some apps keep using cpu etc because they were not programed correctly. (some appz I've found to drain my battery are; Yahoo Mail, Craigslist, AndTorrent and the market if a download is hung up. There are a few others I cant remember off the top of my head) If your phone is getting hot for no apparent reason this may be the cause.
13. Calibrate your battery by bump charging (charge your phone till its full while on, turn it off and charge till its full again. Then bump charge it around 5-7 times) Wipe battery stats if applicable. If you have a car charger, plug your phone in on the way to work to account for the little bit of drain that occurs once the phone is fully charged yet still on the charger.
Remember you can get china made batteries for very cheap. I paid $12 for 2 batteries and a wall charger off ebay. This phone uses the same batteries as the Hero and Evo by the way.

I noticed Yahoo mail and Craigs list apps I downloaded from the market have a memory/cpu leak that kills your phone super fast.

I find that Battery indicator doesnt draw much power if any as I've always used it and never had a problem. The maker of the app states it uses no extra power. I love the circular battery indicator version found in the market. Its not a widget, it stays in the upper left corner of your notification bar. You should give it a try.
Phone doesn't get hot. I've started from scratch twice, I've ##DATA# reset. I had terrible service and data speeds before I did that and it did a number on my battery. Now it'd fine, but it just drains while doing nothing.
I never use task killers or auto sync, I live with spare parts and and monitor it, no real partial wake usage to speak of. I know how to save battery, my hero get 20+ hours with use and auto-sync on.
I'm thinking my battery might be bad. Feels like your talking down to me too, captain.

I haven't had mine a week yet, but atm I'm not getting half the battery life I did outta my Hero running AOSP's Gingerbread alpha.
I'm blaming the crap bloat that's part of the stock ROM.
With the display set to 15-20% I've got the display accounting for 69% of the battery usage. :/
Turning off sync is not an option and I feel defeats the purpose of a smart phone. Additionally, I fail to see the point in paying for 4G and not using it. (I do turn it off if I'm out of area for it or don't expect to be using much data.)
So thus far I'm disappointed in the battery life... but still think it'll improve vastly once rooted and cleaned up.
EDIT: Just did a test running Angry Birds for about 10 minutes... maybe 15. It ate up 9% of the battery in that time. Added another 1% to the display usage.

hey that's really impressive. I thought my 20 hours battery life was pretty good...kudos to you.
def getting better bat supply. especially from my hero which only lasted about 6-8 hours, just got my shift yesterday afternoon. from a full charge: Constant texting, facebook, Zenonia 2 (Downloaded wifi), Snes emu + 11 roms (3G), and customizing it to my hearts content. almost 12 hrs later had 20% until i plugged it up at work.
so far this thing is a golden brick to me
Just out of curiosity, how do you calibrate the battery? Just in case my battery life doesn't match the reports (I know my luck )

Its under # 13 on my 3rd post.
getting great battery life isn't that surprising given you've got a 1500mah battery much like the evo and epic however 48 hours is rather impressive.

Working on calibrating my wifes battery and damn this thing is hard to kill. Even with with everything running for 5 hours its still over 20% finally decided to bring out the big guns. Turned on navigation and the flashlight. I'll post when I see the battery life after calibration.

Edit: Phone plugged in at 7:53pm PST. Now to see how long it takes to charge.
Edit #2: Phone finally fully charged almost an hour after my evo finished its 0 to 100 at 12:19am
Edit #3: Holy F***. This phone takes forever to die and to die. Finally on the second off charge. I wouldn't still be doing this but for the fact that its saturday.
I don't know if it's my imagination, but since the 2.4.6 update, my battery life has dropped a bit. By the time I get into my office from my morning commute, I'm anywhere in the 65-70% battery life after unplugging from a full charge. I haven't done anything new. I always unplug around 8:30 am when I head out, I do some light chatting with gf, browse some sites, check facebook (usually very briefly), and maybe sometimes do a little reading on my device. By the time I get into the office around 9:30 or 10 AM, I'm usually around the 80-85% area with battery.
Lately, doing the same thing, I'm seeing the aforementioned 65-70%.
Is anyone else experiencing decreased battery life since 2.3.6?
I'm on a Tmobile Nexus S, running stock 2.3.6 (no custom ROMs).
2.4.6 ? .... maybe 2.3.6 ... and yes, I also noticed a slight increase in power consuption after the upgrade. The stand-by is still great .. about 0.8 - 1% per hour.
Sorry, yes I meant 2.3.6.
Thanks for replying Ro_explorer. Is your increased power consumption significant? Seeing 65-70% when I'm used to seeing 80-85% as I get into my office, I find, is a large change. To be frank, the battery life of the Nexus S in general isn't so fantastic to begin with... this hit makes it worse.
Anyone else?
I used to get home with about 40-50% after a whole "normal day" (unplugged at 8AM, and getting back home at ~8PM) .. now (with the same average usage) I'm getting home with ~30-40% ... that why I said "slight increase" ...
Not your imagination, I too have noticed this. I hope the next update, will fix this - as I used to get pretty good battery life (even with over 250 apps).
When I recently updated to the 2.3.6, it caused a bug of continuous reboot (every 1-3 minutes), so I had to do a hard reset - now it works fine, but I only have added back about 15 apps - and the battery life sux!
Downgrade OS' it will be ok.
This is so weird. Why is the battery life worse?

You want bad battery life? Try an Evo 4g with a Sense rom. I averaged about 6hrs using a 1500mAh battery, in stock form.
The nexus is pretty light on power consumption, if you ask me. I average 15hrs on the stock 2.3.7 rom/kernel combo, with stock battery.

I'm on 2.3.6 and need to charge every two days. I text a lot and do light gaming. I'm typing this from my phone. Maybe you could drain the battery and wipe battery stats? I'm not even at 50% yet and I charged yesterday.

I also noticed that the battery last less time
I've been waiting to see if anybody else reporting this issue
i noticed a decent increase in battery life going to 2.3.7 and thought that previously the battery life had been fairly poor :\
I am non rooted, and get around 20 hrs on light to moderate use. Again. Stock, non rooted.
How do I recalibrate my battery? I wonder if it could be that...
There are many was to recalibrate. Some involve wiping batt stats, some plugging and unplugging phone several times after charge.
I have always found that using the battery almost all the way down, but not past 5%, and then full recharge conditions it very well.
Oh I've been here to solve the problem
"Why last 2 weeks my Nexus s drain battery so fast ? or I have to calibrate it"
Thank for your notice about update OS to 2.3.6.
I think that's a root cause for me too.
1. Could I rollback to 2.3.4 ,how?
2. Does battery calibration is useful for this case , how?( someone suggest to calibrate when flashing new rom )
Thank you very much..
i want to know who have some methods to do with this stuff

Whenever switching roms, kernels, or batteries, i always perform the following :
1. Charge to a true 100% (Battery Monitor Widget will register +0 to +2 mA)
2. Wipe battery stats using recovery (Amon RA has this option for the Evo, not sure about cwm), Battery Monitor Widget, or a dedicated app.
3. Discharge battery to 0% with normal usage. When the phone shuts down, I pull and re-install the battery and power back up (it will shutdown again very quickly).
4. Recharge battery and be on my merry way.

I found one workaround solution for this issue on
ww.google.com/support/forum/p/Google+Mobile/thread?tid=1684c50cea15282a&hl=en&fid=1684c50cea15282a0004af022e5ed212
Sproogle77 's solution
Problem solved. Using the OS Monitor app, I found that the main culprit was Google Services - the Contacts sync specifically. Even though I had this disabled (only Gmail was being allowed to sync) it was constantly working, apparently trying to fix a location. The message log showed that it was generating continuous debug messages, all about locations - around 10 of these every second.
I have solved the problem by disabling 'Use wireless networks' under the Locations & Security settings.'Use GPS satellites' is still running. This immediately dropped my CPU usage - which had been running around 30 to 40% even when otherwise idle, to around 10%. Google contacts sync is now using 0% of the CPU. The difference in battery life was pretty much immediate and is now back to what it was before - the change in the slope on the battery usage graph is remarkable!
This doesn't really seem like a solution to me, and I don't know whether other aspects of my functionality are being affected, but at least my phone is properly useable again.
I'm testing for 1 day and I think that's working for me.

One reason is that the new version of the stock kernel removed a speed stepping, so it'll power to higher levels faster, thus using more battery.

That actually isn't the problem. I'm using netarchy's kernel and still get this problem.
My battery life dropped from 16 hours --> 6 hours. the slope on my battery usage life is horrible the system is also awake almost constantly even when I'm not touching it / getting no messages.
I will try the fix suggested on the google support forum and see if that does the trick. sloppy update.
Hi folks....m using galaxy note...it's not rooted...the battery doesn't last long enough as it is claimed... is it something wrong with my phone or is this what they mean by long battery life... i text alot and during texting and playing gamea my phone gets warmed up and the battery lasts less than 3hours if i continue texting...my kernel version is [email protected]#2.....please help....

It sound like you have a faulty battery if it only lasts three hours, I think you would have to be gaming to flatten a good battery in that time.
John.
Mine is the same. If I'm browsing the web, using instagram, Facebook and receiving email my battery will go from full to empt in easily 3 to 4 hours.
Backup, factory reset, reinstall apps from market (try to install only the ones you use a lot at first), restore the data you need. If you're still seeing the same things happening, install a battery logger / system logger. Use this guide to see if there's a rogue app that's causing the trouble: http://forum.xda-developers.com/showthread.php?t=937080
If it's still acting up and you cannot identify any unusual drain, I'd ask for a replacement.
After you get things sorted, you can use apps like Juice Defender from the Market to prolong your battery life even more.

thanks guys for the sincere contribution.... i hope your advices help me...
my top battery consuming activities are:
temple run
google play
msging
go launcher
and nothing else
gaming and browsing certainly make the battery drain almost visibly..
things above and beyond the above to try include..
1. reduce screen brightness
2. reduce frequency of or disable background updates by apps
3. no vibrate notifications
4. work more, play less!..lol
the battery life of the Note is great, unless you use it .. a battery monitor will allow you to see the battery drain over time..this will help when you address item #2 above.. if you accept default refresh times, and have lots of social apps your battery can die in 6-7 hrs without even using the Note at all!..
I really love when people give the tip to not use your phone as a battery saving tip

some hints for better battery life
Got mine the other day. First charge battery was fine. Second charge went down 7% in about 5-10 mins. Then it restarted :/ Came back on, down to 88%. Turned the phone off as was frustrating me as it restarted 3 times yesterday. But when I turned it back on I was at 83%?
Hasn't last me the day, it's on charge now. When it pops up telling me to charge it tells me to shut all apps and that using while charging may effect it charging. Is this correct? I didn't think it would have anything to do with it?
3 to the 4 hours continuous use is normal... Only if your phone is standby and then depletes in that time You should be worried. I recommend researching wakelocks in that case.
There are many variables that can atribute to batterylife depletion. Eliminate those first and you will have your answer.
I had best results on stunner version 19. To bad it has the death kernel (leaked ics)

I've found that rebooting the phone after taking it off of charge, the battery life is awesome. There seem to be some wakelocks that kill the battery and for some reason, charging has something to do with it.
I don't know if this is why, but I heard the G2 has special screen technology that greatly reduces battery drain.

Yeah, somthing about 30% lower battery use or something like that. It's 6 hours since I took mine off the charger, must admit very moderate use, some toying, some photos, some mails and 1 phone call. but still, my phone is at 96% battery. My old S2 would be at 60% at this point.

Over 48 hours of use, more than 50% battery left. 3,5 hours screen time. Android system worst offender with 35%, screen 2nd with 25%.

If you look at the programs listed under Android System, try uninstalling the ones that you would never use. This has seemed to help me. But to be honest it was kind of unnessary because the battery life is just crazy badass. In a few weeks or so when the devs have there way this phone is going to be epic.
It is two things, which by the way are great news.
A) LG's screen tech which doesn't refresh pixels when the images are static
and B) IPS
What we can't control is screen power consumption, but guess what? We can control android system consumption through kernels and roms. This means that we can *hopefully* expect EVEN BETTER! battery life since the screen is, for 80% of users, the main culprit for energy drain.
Just a quick note that flashing CleanROM on my ATT LG G2 basically took my battery life from <20% at the end of the workday to just under 80% at the end of the work day with increased use on the CleanROM install. Highly recommended.
Been off the charger since 6:50 this morning. Sitting here at work doing some texting, Words With Friends, and a test call for a co-worker...96% at 12:15pm. My Nexus would have been at 40% by now.
So is Android System different from Android OS?
I normally can squeeze out 15-22 hours since installing Snapdragon Battery Guru. Which has been working great until today.
Here's my situation today:
-100% charge at around 1230am. Light to moderate usage leaves me with
-77% between night before and waking up (only dropped like 2% overnight) at
-830, then i worked from 9 to 1230 so i didnt use my phone too much. But since ive been off work ive been using it more so im not too surprised about my low battery level currently.
But what concerns me is Android OS using half my battery! It says its been active for more than 4 hours and i dont understand where it comes from. Its way more than my screen usage even with a screen time of little over 3 hours.
Anyone know whats up with Android OS? It doesnt tell me what is running when i select it so im lost.
Also ive done many of the suggestions in this thread with positive results. Ive been monitoring my wakelocks and since doing some of the suggestions on here nlpcollector has actually gone down.

Just to benchmark .... I used the phone moderatley ..
I did.. a little over 50 hours of total on time
4.75 hours of on screen time,
2 hours of spotify with bluetooth for the entire time,
2 hours of MapMyRun with GPS running ..
then various text messaging and a couple phone calls
The only modifications i've made to the stop experiance is taking of google's location service for programs, but leaving GPS active .. and changing the screen to auto-brightness, baseline of 50%.
I came from the SGS2 ..... with 1 hour of on screen time and the other spotify and bluetooth .. i'd be around 10-20% after 8-10 hours !!!!!
Mines pretty awesome.

I'm not sure if my battery is defective or not. Right out of the box was around 75% and I drained it until it turned off then charged it to full.
Over the next few days at work it's on wifi and then on 3G/4G before /after work. I pull it from the charger at 7:30am and by 7pm its at 40%. Then on Friday night I unplugged it at 12am with 100% and woke up the next day with 80%. It's dropping like 1% about 10-15minutes. Would a factory reset fix the battery drain? or call for a replacement?

2 hours of MapMyRun with GPS running ..
then various text messaging and a couple phone calls
The only modifications i've made to the stop experiance is taking of google's location service for programs, but leaving GPS active .. and changing the screen to auto-brightness, baseline of 50%.
I came from the SGS2 ..... with 1 hour of on screen time and the other spotify and bluetooth .. i'd be around 10-20% after 8-10 hours !!!!!

wow that's really amazing. ill try that out and disable google location services and see what happens. will that interfere with google now? i mean i would totally sacrifice google now for 50 hours though.

I've been getting godawful battery life - the phone comes off the charger at 8-9 in the morning and I am at ~10% at 3-4 in the afternoon with maybe an hour or two of screen on time. I'm running the latest build of PureNexus and EX Kernel, both of which are supposed to have better battery life. Android System is using 2-3 times more battery than everything else, depending on how long I've had my screen on. Should I switch back to stock (I really don't want to), or are one of these things in particular causing most of the problems?
What about apps??
Install WLD/BBS/GSAM to check the wakelocks..
If that doesn't help (which I think will help hehe) try performing a clean install of the rom+kernel
I have the same setup and I also get not that great of battery life. I get about 2H SOT for 12 hours of uptime. Theres no wakelocks or anything that shouldnt be happening. I just dont get good battery life. I don't even do much on my phone, I just reply to texts, listen to music, and occasionally google stuff.
Check if wifi and bluetooth scanning are on

I didn't even know that was a setting. What exactly does this do? Will it disable any functionality of anything?

It helps with many thing but primarily google now. It enables approx location for searches by scaning for wifi and/or bluetooth signal which is used to determine locarion. and also helps with smart lock I believe. Although that shouldn't drain that much battery.

The reality is... By only doing small and short tasks at a time, it uses more battery. Stopping and starting lots is a lot less efficient than constant running. I am able to get about 4 hours SOT if I do small tasks, nothing prolonged, but if I stream films or longer stuff, I get 5.5-6 hours SOT. It may be worth you looking at one of the scripts for the EX kernel governors, as one of them optimises battery life for users that don't have heavy usage. Do a quick forum search for it, it is worth a try!
The most important thing is to not focus on whatever figure you get for your SOT, as long as the battery lasts long enough between chargers that it is 1) better than your previous device and 2) good enough that it does not run flat between charges, then there is no real issue. People tend to focus on SOT as a defining factor of battery life, when it isn't the only thing to focus on!!
Hope this helps somehow.
Check to see what is syncing for your Google account. I had a ton of crap syncing that I don't even use. I restricted it just to mail, contacts and apps. Also, lock WiFi on to 2.4ghz instead of automatic. Turn off automatically scan for new networks.
Yeah I realize the thing about SOT. I was just giving it a number. Honestly the battery life just doesn't impress me. I wish it lasted until I went to bed, not just when I got home.

It is possible. I started off with diabolical battery life, but now I get through the day with ease. My only issue now is standby time, it is lacking a bit...
