Hi,
I just bought an S3 over the weekend, so far it has been a delight to use and I have a question or two regarding the battery life. I am finding the battery great when I am using the phone, it drops much more slowly than I expected a 4.8" quad-core monster to do It is just the standby time that is concerning me.
Is it normal to have the battery level go down by about 20% overnight? For example, when I went to bed (about midnight) the battery was at 77%, this morning when I woke up at 7am the battery was showing 59% when I dismissed the alarm. That's 3-4% per hour. Running stock, unrooted, XXBLG8.
By comparison with other phones I've used, a HTC One S C2 loses about 2-5% overnight. I do notice that the HTC seems to switch the WiFi off for a good part of the night, though.
Also my phone seems to be suffering the 'cell standby dominates battery usage' issue, but as I understand it that's a bug with how the usage is reported and isn't related to the actual battery life.
You have to flash a cell standby fix or something to make it report the battery life correctly.

You have to use Betterbatterystats and run it and detect what uses your juice.

There next you have to unbloat your phone. Remove or freeze with Titanium backup

At end your S3 have to use max 2-4 % per night wifi and wcdma switched off on gsm mode.
All of the above suggestions worked to reduce consumption while sleeping for me.
Cell Stand By Fix was the biggest help.
Have you made use of any of the built in power saving options?
Another big help for me was setting the wifi to remain off while the phone was locked. Seemed to save a lot of battery power. Not a setting for everyone, especially if you require receiving emails, or other data related msgs while you sleep. If you can wait until you wake its worth a shot.
Thanks.
I've installed BetterBatteryStats and the Battery Monitor Widget to get a better picture of what's going on. Hopefully it will be just be a rogue app or two that I can just blow away.
Also noticed with WiFi Analyzer that the phone's WiFi reception in my bedroom is quite weak (happens with all the phones I've tried but not the iPad!). That's probably making any problem worse.
Using TB to remove the bloatware needs root so I'll wait a week or two before rooting; I just bought the phone and want to make sure there are no (obvious hardware) defects while running on stock first

That fix DOES NOT reduce battery consumption. If only fixes that in the battery graph standby is reported to take a bigger share (10x bigger) than it actually does but does not affect the "charge left" calculation in any way.

For one, apps like Juice Defender may help a lot: they can disable data network or Wifi and periodically (I typically used to set it to 30min) re-enable it so the apps still get their sync, then disable it again.
Alternatively,making the phone fallback to 2G data network will allow you to realtime-snyc without draining battery. HSPA standby seems not to drain noticeably more than 2G on the i9300, but fast dormancy doesn't work everywhere correctly so your mileage may vary.

It's not normal. I'm on stock rom but rooted and undervolted. Mine only consume 1-2% during sleeping time. It's better to know what causes the drainage. Use betterbatterystats. Then you will found out if it's an app or your carrier. Fast dormancy is enabled in other carrier which leads to better battery consumption during idle.

As already stated, the cell standby fix has nothing to do with battery drain, it fixes a wrong reporting of cell standby stats, it will NOT sort out battery drain

Mine goes dead in less than a day, I'm not sure if it's because I rooted my SGS2 or not (chainfire's guide) but then again before I rooted it, I had only used the phone lightly because I didn't know all the functions, but now I know it all.
Anyway, battery life is awful, how are you coping with it? Also are there like genuine branded batters that's bigger than 1650mh that will fit the SGS2?
Edit1:
OK, I have no idea why this is happening, because the default task manager widget on my SGS2 says no apps running, and I've also cleared RAM. I dont understand why, I'm not using some of the programs, like internet or clock etc.
Also, Advanced Task Killer doesn't show xScope 6 or PowerAMP or Clock as running under services, but Battery Usage still picks it up?
Display: 37%
xScope6: 11%
Android System: 9%
Voice Calls: 9%
Clock: 8%

PowerAMP: 4%

Edit 2:
Even after I properly exit programs, instead of minimising, it is still using the battery...
The same programes are still using battery even after I turn phone off, then turn phone back on, i immediately check the battery draw, and bam there they are
Really not having any issues with mine, infact im rather impressed. Have 48% battery life left after 12 hours of fairly heavy use is pretty good in my books. Im confident I could get 2 days use out of this thing if i wanted to.
Just do all the obvious battery saving things you can do!
mine lasts me a good 2 days, with moderate to heavy use, still installing all the apps I want and widgets etc.
Could you post your battery stat screens on usage and stuff?
I want to get a better idea by what you mean by heavy
Mine gets close to dying half way through the day with what I guess I would consider heavier usage. "Display" is definitely always the biggest battery hog haha
With Android OS or System coming in second

It seems like some are getting excellent battery life while others get horrible battery life without any kind of consistency. After I unplugged my S2 this morning I used it to surf the web for a few minutes, played a simple 2D game and then left it idling for an hour and it was down to 70%. Now, 5 hours later, with practically no usage at all I'm down to 45%.

Could you post a screenshot of the graphs?
I guess I must use mine way more than the people here who are claiming all day with heavy use. Because my Display is at 51% right now, and my battery is at 22% after 7 hours
I use mine a lot at work and have the screen on a lot of the time.
I thought these AMOLED screens were supposed to be more efficient than LCD? I could have my iphone 4 screen on all day and I didnt have a battery life problem lol
Hi,
I'm in the same situation. I've found battery life to be so bad I'm on the verge on selling the s2 and buying an iPhone 4. My battery drains at rate of about 1% every 2 mins of use, with the biggest drain being the display. Currently I've lost 28% in 40 mins of use. That's 1% every 1.4 mins.
No apps were running except web browser and wifi.
Would a new battery help? I can't find any official Samsung batteries online, and I don't really want to put a cheap Chinese battery in.
Everyone has updated to XWKE2?
battery life is very poor

I bought a sgs2 two days ago, but the battery is very poor at the moment. Mine buildnumber is XWKE1 and the kernel is 2.6.35.7-i9100xwke1-CL181974root.
how can you update to XWKE2? if i press look for update, then there is no update availible.
battery monitor widget; estimates:
all-time averige = 3h30
average since (un)plug = 6h56
battery (dis)charge = 5h43
offtopic:
Also an weird thing is when the screen goes of and you turn it back on that the sgs2 tries to remove my SD kaart 8gig and then tries to prepair again...
I didn't root my sgs2 (i have a dhd which i have rooted with miui... fantastic!!)
My build says XWKDD, whatever that means. Can someone post noob-friendly upgrade instructions please?

I'm getting results similar to yours, the best I've had so far is 9 hours, with absolutely nothing running, no wifi, and not waking it up. It's ridiculous... I'm hoping I just need a new battery, but like you I can't find any official ones.
I updated to the latest XWKE2 firmware, but it did not have much affect on the battery life. It's still VERY poor. I'm still within the 14 day no quibbles return period, so I'm very tempted to return the phone, or at least ask for a replacement. The frustrating thing is that some people are reporting fantastic battery life.
Play.com are selling replacement S2 batteries from May 20th. You can preorder on their website.
The battery life is really not that bad, here's a post from someone on phandroid;
Scainer said:
Well.... 3 days 3 hours isn't bad from a single charge.. lol (or is that 3d 7h ???)
TBH, the phone was mainly used as a phone with the odd bit of net surfing. No games, and only a GPS sync test e.g. less than 2 minutes.
I only had about 4 calls on it, and data access was only on when I wanted it.
I guess this goes to show that you have the option to use it as a phone rather than a media device and you get a good weekend from it.

And then I tried it out, and I've had my Wifi on all day, had a few phone calls, lots and lots of texting, some browsing, youtube and facebook on wifi and 3g, and a little bit of gps and it's been going for 20 hours and 30 minutes and I still have ~50% of battery left.
If I play games constantly I'll get around 8-10 hours from it so far.
Your one of the lucky ones. I'm lucky to get 7 hours on moderate to heavy use.
Its strange how some people arnt getting normal battery life. A faulty batch perhaps?
Im on 40% battery after 13 hours off charge and ive used it a fair bit today (A couple of 20 min phone calls, some texts, half an hour of angry birds and half an hour of web browsing and i also took about 20 photos aswell) To be honest im massively impressed with the battery performance. My old nexus one was usually down to 10% after a full 12 hour day.
I just hope people arnt getting the impression that the battery life on these phones is bad when theres only a few people having problems (and maybe they have a faulty phone).
mine lasts around 18 hours wifi-on gps-on auto brightness sound on around 15-20 calls a day and 200 texts a day
It's always like this on every device. Really depends on the user, software, and cell strength.
What is the deal with this phone? The battery life is not very good at all. I came from a phone that had a 1150 battery and this one has 1600! I am getting almost identical battery life as my old phone. I am running a fully debloated rom at stock clocks with the display turned all the way down and can HARDLY make it through an 8 hour work day. I've narrowed it down to the screen.
I remember reading about amoled when it was first announced and they said it would consume significantly less power than any other display technology. I'm starting to second guess this.
Its either the screen or the dual core processor that's draining this decent sized battery so fast.

Amoled does. From what ive beem read ing super amoled plus.is alot better. The darker the better. Slcd is.a.good option for battery mizers though.
I voided my warranty and your mum.
Yes ive also read that the way super amoled plus works, is there is no backlight and individual pixels light up, so its better to have simple wallpapers with mostly black, would probably give you better battery life, as most of the screen will no be using any energy.
All android devices murder their batteries. It's nothing new get over it lol.
This device gets decent battery life considering it's the most powerful option out currently though.
The general masses do not understand how to set these phones up for optimal battery life. There are threads all over XDA on how to do this.
This phone for android is probably the best or near best in its class. I am impressed. Its better than my captivate was. I can get through 15 hour days with heavy use all the time with average of 4 hours screen time and i listen to a lot of music when the screen is off.

I don't think is the screen alone itself but the dual-core running at 1.2Ghz might eat more battery than your old phone with an smaller battery

You might want to install CPUSpy and BetterBatteryStats (BBS) so you can better diagnose where your battery issues are coming from. 8 hours seems very poor for this device. Use CPUSpy to see how much your device is running in deep sleep - with light usage I usually see around 80% deep sleep. You can use BBS to look for apps causing excessive wakelocks (BBS is available here on xda) to see if a particular app is causing the problem.
Unless you have a hardware problem, I don't think the display is your problem - the display on this device has a smaller percentage hit on battery use than my 3.2" LCD Aria.

Yet you've completely ignored people who have told you to get CPUSpy and BetterBatteryStats to figure out what's keeping your phone awake.
Most likely your phone is not defective, but you've installed an app that's hogging the battery or set up a configuration option that kills it, such as:
Hotmail calendar sync is known to cause massive battery drain due to a Hotmail server side bug
Some Exchange servers are misconfigured and cause major battery drain
Skype is a battery-hogging nightmare. If you absolutely have to use Skype, make sure to take it out with a task killer when you're done with it.
I haven't really pushed my device with screen-on time, however what are your idle battery drain statistics? If you have drain more than 2-3% per hour when the phone is idle (such as overnight), something is very wrong. You should be getting drain on the order of 1% an hour if you leave the phone overnight in moderate signal.

I havent ignored anyone. You assume that because I haven't responded to such comments that I haven't tried them. I frequently use cpuspy to make sure my phone is sleeping and I use bbs as well.
I'll leave the phone off the charger overnight to check it out though.
This still doesn't change the fact that HEAVY useage at 5+ hours of screen on time is absurd.
I am also planning to experiment with airplane mode and using only wifi tomorrow.

Make sure to do the following to get the most accurate data:
Top off to 100% (to the point you get the full-charged notification)
Remove from charger
Reset timers in CPUspy

I havent ignored anyone. You assume that because I haven't responded to such comments that I haven't tried them. I frequently use cpuspy to make sure my phone is sleeping and I use bbs as well.
I'll leave the phone off the charger overnight to check it out though.
This still doesn't change the fact that HEAVY useage at 5+ hours of screen on time is absurd.
I am also planning to experiment with airplane mode and using only wifi tomorrow.

I'm not sure why you say 5 hour screen on time with heavy usage is absurd? Are you thinking that isn't possible with this device?

This phone for android is probably the best or near best in its class. I am impressed. Its better than my captivate was. I can get through 15 hour days with heavy use all the time with average of 4 hours screen time and i listen to a lot of music when the screen is off. This phone rocks i dont even see the need for a extended battery

You can still exchange with a new one under 14 days or 30 days. 6 hours with screen on is not absurd on this phone in 12 hours. I have been with screen on with 2:45 hrs and voice with 45 min in 1 day and 8hrs with still 15+ % battery juice left.

IIRC, one of the review or comparison against iPhone4S benchmarked GS2 as 5 to 6 hours of internet browsing which means both screen on and using data. Wi-fi gives it a slightly longer battery life than cell data. Unfortunately, it didn't benchmark video playback time. iPhone4S spec says 8 hours of video. I hope GS2 is close to that. This is play video from local storage, not streaming. So, the data connection battery draw is out of picture. I managed to get 4+ hours of video playback with flight mode on with my old Captivate. Hopefully, GS2 will last longer, e.g. survive a coast to coast flight while still have some juice left for navigation.

He's not lying. I have seen 5 hours of screen on time and still had a little juice left at the end of 16 hour days. And it wasn't a one time deal. Seen it several times, though I usually don't use my phone that heavily. Yesterday I barely used my phone at all and was only down to like 85% after 16 hours.
Just like the title says, after 5 hours of light usage my prime factor for battery drain is CellStandby at 42% (the phone itself was down to 70%).
Anyone experienced this so far? I'm aware that LTE is rather demanding but it can't be that bad vs HSPA which drained next to nothing on standby

It's a bug in the software.
Thanks, I did search (albeit quickly) in the forums here and didn't see any mention of it.
I did see an article about the international model being affected by a similar glitch so.. all models would have this ?
I've had the phone for 5 days and gone through maybe 8 batt cycles. I'm not getting more than 2hrs screen time on any cycle. This is stupidly horrible battery life. There has got to be something severely wrong. I don't do much with the phone. I can't even with less than 2hrs to work with. Overnight batt loss is maybe 8%.
Any help is ENORMOUSLY appreciated.

I believe all have this bug. It's just that, a bug. And there is a fix, but I'm too lazy to apply it. (Assuming it works to fix the bug in the U.S. variant software)
I'm on HSPA with TMO but it seems to depend on reception more than anything in my experience. Here's my log from today:
Lol, sorry for the huge image
a bug as in it isnt actually draining the battery or it is really draining it?
I'm in the same boat, and there is no way that the standby is just a calculation error. If I sit and use my phone continuously after charging I can get 2 hrs of screen time while the battery drops from 100% to ~65%. During a normal day of light use I completely drain the battery and my screen time might be 1h50m at most. So something is definitely up - although I'm also getting terrible signal strength, and I think that might have something to do with it. I've searched every thread and have made sure that I have no rogue apps or processes consuming the battery either.
gary
edited - I take it back, after restoring my phone last night I have gotten 2h25m screen time after 11h45m since charging and I'm at 17%. So, doing better but not great by any stretch.

Hi guys
This seems to be an issue on all SGS3s. I have both the LTE and international model and they both show high cell standby. Check this thread out for more info on the i9300 forums to understand why its showing so high which is actually a calculation error
http://forum.xda-developers.com/showthread.php?t=1732722
My i747 is rooted so I decided to make a backup and flash the zip fix they provided and seemed to work. But the risk is inherently yours if you want to try it. Its just an xml file so I wasn't worried trying it in my case. I am more sending the link so you can see why it reports using so much battery
My cell standby battery usage went from over 50% to 5%
Basically, cell standby is not really killing your battery, it overestimates the power usage as being 10X more than what it is from my understanding

Yes yes yes! This is exactly my experience too! There must be something wrong if all others report 4+hrs screen time and we can barely break 2hrs. I'm in San francisco. My previous atrix "4g" would do at least 3hrs during my day to day.
Please, help. I'm really sad. Was really looking forward to at least an extra 30min over the atrix in my day to day.
So is the battery actually draining that fast with the cell stand by issue... Or us the battery actually higher charge than reporting?

Are exactly the same thing I'm also experiencing. I've come close to taking it back and exchanging it for another one but I'm not sure if this is how all of the US versions of the S3 are. Been reading through threads here and posted on a few of them and it looks like short battery life is a pretty common problem. I hope someone comes up with a fix pretty soon before I run out of time to exchange or return it.

You are close, but not exactly right.
When writing the software one of the developers entered 34mw for how much the battery should drain at standby instead of 3.4mw. A simple typo, but im sure if there isnt a fix already that there will be soon :]

There's a fix that's available on this forum but that only fixes the reporting. It doesn't fix the poor battery life.

Should we start a new thread? I've been posting in all the various battery threads to avoid getting yelled at for starting a poor battery issue thread. You're the fifth person to note the same issue. I too restored my phone this morning and it seems to be doing better, but still nowhere near what others are reporting. Also not nearly on par with my previous Atrix.
Maybe we have valid reason to start a new thread?
I applied the fix but still have poor battery life. Just as bad if not worse than my epic 4g.

CDMA people make sure you post your carrier when discussing battery life. GSM battery life for me hasn't been too bad. 10 hours constant use or so on wifi and around 6 hours or so on hspda. Standby time is very good. Especially for stock kernel.
I'm sure we can get some more once the LTE switch gets added.
That fix is just for the calculation of cell standby drain, not for how much it is actually taxing the battery. Several people on AT&T seem to have a real problem with excessive battery drain in standby, and (for me at least) it seems like it's happening when I have a poor signal. Unfortunately, that is mostly all of the time.
I found this old thread, and the APN listed there seems to help. It's just an interim solution though and I have to imagine AT&T will have a software fix for us soon.

I've noticed with Wi-Fi on, I always lose 1% or a bit more per hour, just idle. On 3G, it's a bit less than 1% an hour.
I'm running the latest Jelly Bean stock official firmware (DLJ4).
I have good battery while the screen is on (1% every 4-5 minutes while browsing the internet on WiFi), but this idle battery drain is a bit too much...
I have Facebook setup, but not syncing, and I have most of the notifications disabled.
For my Google account, I have Gmail, Calendar, Contacts, and Internet set to sync.

Screen was on for 1min and I received a call which I did not pick up.
BetterBatteryStats did not show any kernel wakelocks (although on previous days I did see wlan_rx_wake, l2hsic, and a few others, but none today).
I have seen all over the forums that some people are getting a 24 hours of battery life with 5 hours of screen on time, with Wi-Fi on all day. The best I can get with a whole day is 3-4 hours of screen on (brightness at 40% or lower).

6-7 hours in a 24 hours time period? Or nonstop?
Wow. Factory reset maybe ? Last night with wifi on I lost 2% for 6 hours sleep.

Looks normal, Gmail woke up to check mail 20X over the cell network while it was sleeping?
Was the phone in a good signal location?
Reason I use Wi-Fi when possible at home. CDMA is 20% signal here, GSM 90%. Perhaps your in the same situation. It is idle in GSM mode, wakes up to check mail notices it can go faster and wastes power renegotiating a faster connection?
That could easily waste power...
If so set to GSM mode, with Wi-Fi on (if screen is on) and turn cell data off.
If your signal is good, you can forget about using only GSM and just do the rest.
Not sure what else it could be, feels like cell signal IMHO. It looks high in the usage chart too, unless you made a few calls..

I lose about 20 - 25 percent per night when Wi-Fi is on. When Wi-Fi is off almost no battery loss... See the attachment for a log. I'm wondering what's wrong... So I would say that the TS is lucky to be losing only a few percent per night!
Battery drainage looks normal to me. Your wifi was also on for almost the entire time. You could use an app like Juice Defender or Tasker to schedule times to turn on wifi for syncing. That could help decrease time wifi would be on, thus saving some battery life.

It's not normal at all. I've seen others with better idle time than me, leaving Wi-Fi on the whole time. Also, my phone drains less battery while on 3G. That makes no sense.
And apps like Juice Defender shouldn't be required. It cripples the phone of a feature: background data. I use Google Voice to text and prefer my messages to come instantly instead of every 15 minutes.

I was on Wi-Fi the whole time, so it wasn't using the cell network (3G).
As you can see from the battery graph screenshot, I was mostly in a good location. The phone was in one spot on my table the whole time, where it switches between 3 and 4 bars every now and then. I didn't make any calls but I did receive one (didn't answer it) right before I took the screenshots.

I have never heard of ads running in the background... and I had all apps closed so nothing was running to drain the battery.
I've done factory resets several times, so I suppose it's either the kernel or an app doing this... but the apps I use are very common apps and I don't sync much :L
Avast shall halt anything misbehaving, maybe worth a try? Only other thing worth trying before a factory reset is installing Watchdog task manager.
Set it up so it monitors system level tasks!
Something might only be awake for a few seconds in battery stats, but it might be running at 100% system load.
Watchdog shall catch it!

My phone always drop like about 25% when I sleep with Wifi on too. Wifi seems to eat up the battery a lot recently.... I9300XXDLJ4 with Siyah 1.7rc1....
I'm the same with WiFi on and seems plenty of others are too. If I charge phone to full and then disconnect charger, with WiFi on I get a drain of 4.3%per hour, with WiFi off its around 1%. I am now leaving WiFi on all the time but changing the option to always leave WiFi on when sleeping to never and it's middle ground. There are far to many people moaning about this to be a coincidence. I am on stock latest jb and performed full wipe and reset and no difference. Ics had better standby time with WiFi on, fact!

Same here yesterday I tested with full charge and with nonstop usage I was able to get 6hrs 8min with 21% percent battery left, however my battery drains quickly in standby mode. In 6 to 7hrs I loose about 20% to 34% when sleeping.

I see you're not on Wi-Fi a lot; are you on 3G or 4G?
4-5h screen on time with 3G/4G is the best you can get in a typical day.
Hello , XDA forums , I am new here.:d. Recently , I think about a week ago I bought a new android phone , a L9 P760. The last 2 days the battery started discharging quickly, I got a battery app and it shows me that when the phone shows 100% charged it is 1500 charged. This phone has a 2150mah battery. What could the problem be?
I had the same, adjust brightness in ur settings i have on 50 percent. Or hold down home button and close some apps.
Maybe it helps.
Sent from my LG-P760 using xda app-developers app
Already did that, screen is at 25% , played World of Goo for 20 minutes and the battery went down from 40% to 15%. Yesterday when I went to sleep I had 50% and in the morning I had 45%. Forgot to say , I charged my phone for 12 hours 3 times , could that be the problem?
I think I might know the issue. Do you have a Bluetooth headset paired to the phone? My P769 seems to sometimes keep the link open between my headset and the phone. I know this because I hear a slight hissing noise in my Bluetooth earpiece from time to time. Even when the phone is idle.

Uninstall app
Try uninstalling app or try back up and reset the phone only then we can know whether its software or hardware
I have same problem. Charged device at the evening. Played angry birds for 20mins (battery was at 60-80%) then went sleep, and phone discharged, even turned off during the night, with no use, in idle. Checked battery consumption and it said Android operating system had 60% battery consumption, even more than display.
Device is pretty much new, I have there like 4 applications, wifi, bluetooth, 3G turned off. So where might be problem ? Thanks.
/edit: Done some research, for Rassva - battery application shows 1500mAh because its set to 1500, application doesnt know capacity of your battery, simply change capacity in app.
And another thing, that discharging battery overnight is some rogue app, that wakes your phone regularly, or application which doesnt permit device sleep, you can check this by checking your whole time of battery used and wake time, if its almost the same..there are this kind of app.
I have this problem, but cant find out which app it is.
My L9 P765 have 2150 mAh battery as offered by LG and works amazingly great. Given TWO FULL DAYS (48 HOURS) with heavy usage and 3G on for most of the time in a day. Its rooted and I have removed some LG crap apps which roll in memory all the time for no good reason. Also use ATK with every half hour crazy killing.
Hats off to LG for such a huge battery backup with such a thin battery. No I am not LG salesman, rather a long time LG hater due to O2x , delay in ICS and locked bootloader..
Done hard reset, some settings (disabling some pre-installed apps, turned 3G off, and so on)... nothing new installed and wake time is still same than up time. Do someone else have similar problem ? (I assume that up-time is upper time in battery usage graph, and wake-up time is lower one)
I am using battery spy with my L9 to monitor the battery voltage.
When charged to 88% the voltage already went up to 4.24V ..... that is way over voltage .... and yet it still continue to charge.
Should I trust the voltage from battery spy?? What other Battery App do you use and have your noticed the same over voltage issue??
I have charged my L9 to full twice since I received it few days ago .... without knowing/montoring the battery voltage.
If it indeed let the battery over charge like that the battery will goes to smoke very soon.
Your comments please and thanks.
This phone have 2150mAH battery which is too much more than standard batteries (1300 to 1600mAh), hence the battery is not so bad how it appears with you.
Even without any tweaking it should go above 35+ hours, as I dont have anything special, its pure V10C Stock with no memory tweak, except ATK.
Now if you pals are really getting so bad performance, I suspect the bad battery issue. Its possible in thousands of phones sold few may come with bad battery in-spite of factory testing.
Just a tip. If your phones and batteries are in warranty, please get it checked or replaced as few hours life is certainly not reasonably possible with L9 as per my observations.
Also have LG Optimus 2X, with three years old battery and still giving 24+ hours uptime on recently flashed Stock V30B ICS KDZ. I already mentioned, with L9 I got two full working days with business usage, calls, emails, 3g, wifi, etc. Or am I too lucky?

This phone have 2150mAH battery which is too much more than standard batteries (1300 to 1600mAh), hence the battery is not so bad how it appears with you.
Even without any tweaking it should go above 35+ hours, as I dont have anything special, its pure V10C Stock with no memory tweak, except ATK.

For me same. 48 hours, stock rooted V10a L9 P760. 2 hours of calls, some SMS, Wifi, Angry birds...
But when I launch NFS MW it goes down in few hours
thanks for the app info. I have installed another battery app and the voltage reported is the same so I will be running battery spy only for now.
For me keeping 3/4G mobile data on kills my battery. After 6hr49min idle (phone screen off I get the stats below:
- 48.7% deep sleep
- 43.8% @ 300mhz cpu
- 6.9% @ 1ghz cpu
- Battery lost 27%
- this is with WiFi/BT off. Only Mobile data on.
- 769BK 10e Stock ROM. Nothing changed.
With mobile data turned off and only WiFi the battery life seems to have improved A LOT. Will confirm that with longer term testing.
I am on T-Mobile $30 plan and my area is marked as the best signal in their coverage map.
For me it may work ok cause I am using csipsimple/pbexes exclusively for voice call; I just need to manage to turn off Mobile Data whenever I have WiFi coverage; but if I am on the road for extended period battery will be a concern. May have to get an extra battery.
I recall seeing a list of apps that can be safely disabled but lost the list now. Anyone have info for that??
Any other battery tips??

Now if you pals are really getting so bad performance, I suspect the bad battery issue. Its possible in thousands of phones sold few may come with bad battery in-spite of factory testing.
Just a tip. If your phones and batteries are in warranty, please get it checked or replaced as few hours life is certainly not reasonably possible with L9 as per my observations.
Also have LG Optimus 2X, with three years old battery and still giving 24+ hours uptime on recently flashed Stock V30B ICS KDZ. I already mentioned, with L9 I got two full working days with business usage, calls, emails, 3g, wifi, etc. Or am I too lucky?

Woow 24h with the lg o2x.... mine is 20h max at home with wifi. And out side like 15h maybe with only 2g and data on...
Stock battery.... on cm7 didnt like tstock 2.3 and ics they say battery aint that good.
But should i buy this one. I mean is it the same perfomance as the o2x? I still cant find if the powervr540 is equal to tegra2..
I found out, that one of application actualization (youtube, chrome, google music play, street view, or voice search) had impact on device..keeping it awake for long time, which could be seen on battery...dunno which one app caused it...better uninstalled it all.
/edit.: according to other forums there is a problem with chrome update, which depleting battery drastically
Looks like tha weather was the problem , It got a little bit hotter here and the battery works like a charm , after a day I still had 68% .
I have the same problem! Any fix tips?
