10% battery drain in 8 hours of little usage.
In average 50% at evening
but drains a lot when playing some games
What'S shown in your battery stats?
Did you do a full wipe before flashing?
Try a full wipe and reflash - only with little market apps installed

i did a full wipe with the tool you gave in your site
im using 3g
very few calls and sms
no games
very strange
every hour 20 % less

That's defintiv much too much.
Look at battery stats in settings - phone-info - batterty - drain (or something similar) if any market app drains your battery.
Did you restore system(!)settings with titanium?
Last exit: wipe everything (eg from recovery - I'm not lbc,so it's not my tool ), redownload (md5 sum!?), reflash - and do not install any market apps for the first hours. Battery drain should be max 1% per hour with screen off.

Did you perform the battery re-calibration that is recommended after new ROM install?
see LBC post http://forum.xda-developers.com/showpost.php?p=14981516&postcount=581 where he corrected the previously written method.
I'd recommend following these instructions and then check battery usage again.
This thread should not have been started here in Development section, but either as post in LBC ROM thread or as new thread in general.

I never ever did such a re-calibration, but perhaps it helps...
Normaly battery indicator is correct after at last 2 days of normal usage (I always plug in over night and never turn off the phone - so seems that it re-calibrates itself)

mod please...

I had the same problem with lbc 0.5.2. The battery life was like 12 hours normal use.
So i went back to lbc 0.5.1 and everything works fine. Standby time now more then 36 hours.
Maybe this will help you for a while.

Sorry to repeat, but did you try battery re calibration yourself and not the version described on post one of LBC thread but the new and corrected version where you reset battery stats using app at 100 mentioned in post #581

Hey, sorry that I don't wrote that I tried this too.
I wrote with LBC about it. He told me, that he dont has the problem.
I also thought, that maybe the value isnt right, so I dont recharged it, but at 1 percent the phone turned off.
With 0.5.1 I dont have any problems.

mine drains fast as well...
I have followed all the instructions for a newbie with android in terms of saving battery life, but I still feel that my battery drains fast than the normal. Here is the scenario...
Full charge @ around 10-11pm, with one hour extended charging.
Turn off wi-fi before sleeping @ 11:30pm.
In the morning, battery is at 99% capacity as per battery indicator. Screen is at 25% brightness.
Turn on mobile network connection upon arriving at work @ 7am, there's no wi-fi in the office.
At about 9-10am, battery indicator is at 52% capacity. I normally use my phone in browsing Facebook, playing a li'l poker before working (my office is secluded), some browsing etc. I don't watch videos on my phone.
At around 12noon to 1pm, I connect my phone to USB charging in my PC, battery is at 25% only.
I don't think this is normal. My best guess is that the network connection is draining my battery, but I have no other choice but to use it. I'm need it turned on while in office to be connected to the outside world...
Anyway to extend battery life???

From 99% to 52% in 2 to 3 hours?! No that's not normal. Install "better battery stats" from this thread...

Does this mean you are connecting to data through the mobile network?
Is your wifi connection still switched on as well?
If wifi is searching for a connection all the time this will seriously drain the battery.

Depends on their sync settings. The battery stats app will show you which is the greatest consumer. If it happens to be facebook, dial back the usage. I used IM+ briefly, but uninstalled it. I can't remember why. I'm not on facebook.

I do the calibration after any flashing of custom rom. And it's allways helps to me, battery live is 2-3 days after this, and 1 day or few hours if not calibrated after flashig new rom.
Android 2.3.5 roms drain battery mush lower, and work faster. Flash it and calibrate battery after.

Maximizing Battery Life

What do you guys do to maximize your battery life? I just can't seem to get decent life. Average is probably 5 hours with heavy usage.
Any recommendations?

The usual - brightness as low as you can stand, radios not in use turned off, screen timeout 15 seconds, 200-1400 conservative governor in SetCPU.
Search AutoKiller in the market -- choose "optimal" profile, so far has given me an extra two hours today over what I got yesterday.

5h of heavy use is good already.
You can tweak your idle batt life, 2g-only, undervolted kernel, avoiding power hungry rom.

Idle battery life is just amazing with stock... just test it over night, 6hrs get 2/3% for me.
I can get 30hrs with 4hrs with screen on, the screen is the key here, i can get 5hrs with 4hrs with screen on too. ;o)

I tried almost every single combination of rom + kernel. And for me, pure stock has the best battery life, by far.

See my signature, stock (rooted and removed soom Google apps) with Trinity, works together just fine

How would you define "heavy" usage?
Also, what does your "battery use" stats say? (Settings - About Phone - Battery Use)
5 hours of truly heavy usage (online gaming, for instance) is actually to be expected.

You can create a custom prl setting. Turn wifi to never sleep when you're at home... Have the prl to auto *CDMA or GSM* Which ever your network is on. (This goes to all Nexus S. users). So you have wifi on with a signal and 3g off. The phone stays in 2g for calls and uses wifi for data. Turn off google location services while your at home, turn off roaming, turn all of that off. I get about 13 hours of battery life with heavy usage. People think wifi drains your battery but it doesn't if you have mobile data turned off. When you have 3g turned on it's constantly searching for a better connection. If you have wifi on and a strong connection it isn't constantly polling.

are there any charging habits that would help prolong battery life? I usually just charge my phone every night cause, if I remember correctly, these batteries don't have a memory or anything. anyone know if that is the smartest thing to do?

I hope you don't mean overnight. I don't know if phones have auto-cutoff feature (a la laptops), but it's safer just not to charge overnight.
I personally use an extension that has a timer built-in. Nifty. Set the timer, plug the phone in, it will automatically start and stop the charging at the predetermined times. I usually time the charging to end right before I wake up, so the battery doesn't stay fully charged for too long. I heard batteries corrode faster when they're fully charged.
When my battery life starts getting shorter than usual, I let them drain until the phone turns off automatically (well I actually try not to get to that point, but seldom succeeded ), and as soon as possible charge it until full.
Usually the battery holds longer then. It has something to do with teaching the battery about the true empty and true full.. or something.....
AFAIK. CMIIW.

doesn't the nexus s have a built in cut-off feature so it will only charge to 95% though? I figure that would take care of the full charge issue. i'm also not sure if lithium ion batteries have a memory, but you could always reset the battery stats if you're on root to compensate for the whole draining and fully charging thing.

Battery stats! That's the word I was looking for No I wasn't referring to the memory effect
I don't know what would happen when the cut-off feature kicks up. My Nexus S still shows a charging icon even a while after full, so I don't wanna risk it.
The best way is by touching the charger unit after a while and see if it's warm/hot. If it is, it's still charging. But you gotta give it time to cool down first (after it's finished charging) Haven't gotten around to it, though. Always forgot to check the charger

lol, I know that my phone for sure won't charge to 100% from watching it, so even after a night of charging it's still at 95%. I've read a few explanations on this forum about the whole not fully charging thing too, so i'm pretty sure that it's like that on purpose.

[Q] High battery drain (50-100 mA in current widget in sleep)

I have an unlocked T-Mobile Sensation 4G and I've tried a lot of different rom (with Sense and AOSP, GB and ICS).
I had made battery calibration every rom change (Full charge -> wipe battery stats -> do some full discharge/charge circles in normal use).
Every time I have 50-100 mA battery drain in "sleep" according to Current Widget and another battery widget (tried another to commit that Current Widget tells truth).
The phone settings are maximum power-saving:
Fixed small brightness
2g only
Data and auto-sync are turned off
Wifi only if needed
CPU is downclocked to 1.2 gHz
Battery is stock. Phone is two months old.
In my regular usage (1 hours of calls, 10 min wifi) phone dies in 12 hours after full charge.
It is not my first android and I'm not a total noob. My Desire HD with one year old battery live 2 days with my usage.
Also I notice, that sometimes battery left is not accurate and changed after reboot to a bigger value. For example, 80% left -> reboot -> 82% left.
Any suggestion?
Thanks in advance!
Sorry for my poor English...

My suggestions:
1. Use system tuner or a similar app to check up on which apps are draining the most power (keeping the CPU on, etc).
2. If no culprit can be found, full wipe and reflash your ROM, and refrain from downloading any apps, see if that improves battery drain. If it does, slowly install more apps until the battery drain goes up again, and you'll know whats causing it.
3. If reflashing does not help batter life, you might want to try another ROM or kernel.
4. If none of those help, or even if they do, I highly recommend an ANKER battery, it'll at the very least boost your battery life a few more hours.
5. If the battery life still sucks, then it might be a hardware issue and you might want to get it exchanged or whatnot.
I used to have the same high battery drain problem, but after flashing new ROMS/Kernels and switching to an ANKER Battery, I now get 2 days of light/medium use out of my Sensation.
Currently using Insert Coin 4.5.0 with 1.5GHz overclock+undervolt if you're interested in trying.

How much does your battery actually drain overnight? Should be around 1% per hour or less if all is well. Disregard currentwidget in deep sleep mode as the Sensation has a very broken meter.

I'll check it this night.
With jumping battery meter I don't know if these values will be correct. But when the battery value reaches 0% the phone shuts down immediately and don't turn on. So 0% it counts well.

i think im also having the same issue . i checked current usage when in sleep mode.its between 50-80

12hrs with the standard battery is actually very good for a sense build, without sense it should go around 15 - if the battery is in good condition. The battery driver for the sensation is very buggy and you won't get accurate results with any measurement app. Don't worry about the standby or inuse readings as they will both be wrong.
If you're battery drains faster than 1% per hour in standby, assuming you are in a good signal area, then use a system info app to see which program isn't sleeping, then uninstall that program.
But it doesn't sound to me like you have a problem.

According to the log file it drains 1-2% in hour (now I'm using aosp build, MIUI). I think, new Anker battery is the only way. Thanks to all!
Maybe in the future we'll get a more accurate battery driver...

Anyone got any battery tweaks?

CM10 battery life is pretty poor, anyone found a solution? I remember on defy someone improved by using stock battd folder in place of the original one, however desire s doesn't have this folder. Undervolted, full charge cycle, disabled auto brightness light to moderate use and only 8 hours. Display is main culprit according to system, maybe its getting too much voltage or something?

Perhaps you should calibrate your battery with an app like battery calibration
"It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break."
Make it twice or three time then you should see a difference.

Battery stats is a myth: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
The difference seen is purely down to the full charge cycles done in this method, after about 5 days the battery stabilized anyway, thanks anyway

I have the same issue on Pacman (CM 10).
My - I hope temporary - solution is to disable 3G as much as I can. For everyday usage, 2G (Edge) is sufficient for me. At home I am on wifi anyway, so I perform the heavy tasks then.
I noticed a very big difference when using 2G only vs. mode "3G preferred". It seems that there is a 3G battery draining issue with CM.

3g is known to drain battery. Keep it at 2g for better battery life.

[Q] Battery pff.. should I root?

Hey guys,
I'm a new Nexus 5 owner and I come from the HTC One S (which is known for a terrible battery). Although, my battery on the Nexus 5 is even worse compared to my setup on the HTC One S. With light use, I'm glad to get around 10-12 hours of it.
Is it worth rooting battery wise? I mean, are there roms / kernals that significantly improve battery life? I'm no gamer, but I do browse and use social media apps..
Thanks in advance!

Hi,
Flash another kernel or rom will not obviously improve your battery life. Battery life depends mainly of your use, apps, settings (like screen brightness, synchro), data signal quality, etc... and even more the rom has nothing to do with your battery life.
For example if you have an app with a ton of wakelocks, flashing another kernel or another rom will not do better... You use social media apps, in general the battery drain can come from them.
Maybe in first you should identify the cause of your battery drain, no? Post your battery history for example and use Better Battery Stats: http://forum.xda-developers.com/showthread.php?t=1179809.
You said "10-12 hours" but what about the sreen ON time?

To get things straight.. flashing a custom kernel only requires the bootloader to be unlocked or?

To give an update on my current situation:
52% battery left (7 hours and 24 minutes since charge).
Screen on time: 1 hour, 54 minutes.

I would say you are in the average, but without knowing more details, hard to tell more...
Wi-Fi?
3G/4G?
Good signal quality?
Screen brightness?
Synchro?
Etc...

That extrapolates to almost 4 hours sot. That's not bad. Franco kernel can probably get you a bit more.

Those two things plus turning off the "Ok Google" may help. Also do you have the camera battery usage bug?

You can check how much battery life your device has left by doing one of the following options:
Use Quick Settings or View the battery graph.
However root manually if possible because rooting itself doesn't change battery life at all. Bettery life generally depends on our Apps that we are using on our Smart phones.
Roms / Kernals will not improve your battery life.
