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?
Sorry if there is already a thread, I don't have a computer right now and I don't think I can search on tapatalk.
Thanks in advance.

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)

Try a kernel that is made to optimise batt life with display active, like the XTEUV92 Trinity kernel.

I tried almost every single combination of rom + kernel. And for me, pure stock has the best battery life, by far.
But i'm getting bored and should flash something... )
Ps: afaik trinity doesnt work with stock. Did it change?

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.

i'm using the same stock 2.3.4 as your signature and tried the morfic kernel from yours, but got no lock at all, freezes and reboots...
that's a little strange for me, first time i see it in my device... =o\\

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.
Note: I searched the forum and saw nothing like my issue, if there is then I missed it and I apologize.
So here is the issue. When charging it gets to between 85-90% then immediately jumps to 100%. Have tried clearing the stats, draining, then full charge. Any suggestions on this?
How old is the battery are you charging USB or AC?
Most likely its a old battery

very odd, I've actually experienced the inverse. Charge would hold at like 20% and then jump to 10% in a second. Are you noticing in use there is a jump back down i.e. when you unplug, does it jump from 100% straight to 90% or does this just happen when charging. If it just happens with charging, I'd say run current widget and see how much mA is left when it makes the jump to 100% and see if the battery is actually charging correctly. In other words, if you're charging and the battery jumps from 90 to 100 and you still have like 200 mA left, something is goofy with your battery and I'd recommend a new battery or at the very least full wiping and reflashing your ROM.
If it jumps and the remaining mA is like 30 or something low, then the actual battery seems to be fine and I'd recommend a full wipe and reflash the rom you're using. In all honestly, it's probably the battery and may just be worth getting a new one.

Im not attacking you im just trying to clarify. Are you saying it jumps to 100%, meaning you see it say 100% or are you referring to the led going green at about 90%?
I'm not convinced it is a battery issue... I've only very recently rooted my phone (have had it for 11 months) and haven't had the charge indicator jump past the last 10% like it did just today.
Looking at the last 26hours of history (ICS 3.0.0 install), the initial battery discharge showed normal taper from 100-85%, however on charge it jumped from somewhere just below 90% to 100% instantaneously.
I should have taken a screenshot, but instead I wiped the battery stats and am in the initial discharge cycle still. I've had the phone 11 months and have never cleared the battery stats before.
Maybe 8 months old.

When it hits 85-90% the led turns green then it shows 100% right after that.

the led is supposed to go green at 90% to indicate trickle charge mode. but ya that should not be triggering the 100%. are you using a battery mod that isnt included with the rom?

Run the battery down until the phone dies. I have had this happen to me before. When I got down to 1%, it took a really long time for the phone to die. Recharging and doing a couple of long cycles of letting the battery go down to a really low level before charging fixed it. Do not delete battery stats as it does no good.

Well if calibration processes fail to correct it, then I would suspect a bad battery.
Sent from my Inspire 4G using Tapatalk
You might try an app called Battery Calibration. Found here http://forum.xda-developers.com/showthread.php?t=1024867
I don't necessarily use it to calibrate but to monitor the mV. It might help in seeing if it is in fact a bad battery or if your battery indicator is showing a false reading.

Then it may be that time. I got my battery to hold out a little longer, but soon after, I started getting bad drain. I recently replaced my battery and haven't had issues since.

Sounds more like a battery calibration issue than a battery issue.
Give it a bit of thought... from 90% it skips to 100% when charging. However at 1% it camps out for an hour or more before shutting off. This indicates an issue with how the charge of the battery is being measured/expressed...
Now let's think about what is happening behind the scenes. This measure of charge is "defined as the available capacity expressed as a percentage of some reference, sometimes its rated capacity but more likely its current (i.e. at the latest charge-discharge cycle) capacity but this ambiguity can lead to confusion and errors. It is not usually an absolute measure in Coulombs, kWh or Ah of the energy left in the battery which would be less confusing. "
Essentially, the way the phone is measuring the battery isn't working correctly. However, is the duration of the battery life what you would expect given your use of it?
If YES, then it's a measuring issue.
Does wiping battery stats too often due to flashing alot of roms reduce stock battery performance ?? Being curious..

No. The battery stats file is only used for determining battery drain. It does not have an effect on battery life one way or the other.

wiping battery stats does nothing to your battery and actually the battery stats are wiped automatically every time u fully charge ur phone:
Dianne Hackborn said:
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

If the battery stats get wiped every time it hit 100 how one can keep the same battery life daily ?

The only way to really preserve a battery is to fully discharge, fully charge. Mine was going great until I slacked on it. I started only charging a little, fully charging from 40%, etc etc. Now, I'm on 100% for two hours. Then I drop fast to about 80%. Then I float around 80 to 60% for a few hours but once I go below 60%, boom, 20%. The last 20% go quick too.
Don't get me wrong, my battery life is basically the same, but now it's really inaccurate. If you start to feel this, the best thing you can do is fully charge, fully discharge. Do that a lot, over and over. It might help correct it, might not.
But to reiterate, no, wiping battery stats does nothing.

its not really a 100% with those kernels, he will still actually charge to his 95% even though itll say 100%. its just a cosmetic fix. if you actually want to see 100%, charge it to your normal 95% then charge the rest of the way with your screen on. itll eventually hit 100%.
i finally found the answer to my battery
thanks to this thread...
95% is normal
Mine says charged, 100%. on a 1500m milliamp batt and the Sprint backup batt I bought that's a 14xx.

Ok on start I am sorry guys for my language. I am in UK only one year so I need to learn a lot
10 min a go I back from SSC because I have problems with battery/ charging and foulty speaker
Italian Job 1.0.0 - big battery drain and battery go dawn after restart by 30-60%!
XXMC8 - no battery drain but battery go dawn after restart by 30-60%!
Stock UK GB XXLK7 -no battery drain but battery go dawn after restart by 30-60%!
So I bought new original samsung battery 1500mAh - no changes
So I bought batttery 3500mAh with special cover - no vissible battery drain, this battery can handle my phone by ~ 20 hours of playing AVI movie, 720p in loop in MX Player so very good score but battery go dawn after restart by 30-60%!
All battery was tested in my Ace 2 and in my girlfriend Ace 2 (she have fully working phone with no problems) and she have good scores on all batteries but best is on 3500mAh with special cover ( above x2 than standard)
So i went to SSC and they: (stock GB, 0 flash counters)
- take my phone without documents on free guarantees (only box)
- I must come back for that phone in this friday
This above is for + but:
- they **** that work because I have in my ducuments copy a lot of bugs! (street , town)
- they checked my speaker in noisy room (it did not take nearly as booming)
- for those guys after restart when phone loses 30% battery power is normal!
So I go after tomorrow for my phone and we will see ( They will make updates to JB! and they change speaker/ charging module)
Photo for proof attached
If they dont repair my phone I do not buy samsung phone NEVER AGAIN!
EDIT: 3 hours waiting for a response about taking my phone!
EDIT 2: that 3500mAh battery must be loaded 8 hours to get 100% form 0%. (standard charger )
I really want to know what the whole battery dropping after restart thing is about, forever happening to me and sometimes the battery completely dies. It was the same on my original Ace S5830 I got a few years ago.
If you find out, please tell! haha.
After receiving the reply I upload it here
Have nfc version and ni problems with battery with much using and sometimes little bit playing i rech two days
I dont have problem with battery (any) but with phone hardware
I must agree with you guys regarding battery drain. It's suspicios and I am also aware of a fast battery drain from 100% to 65% in just a couple of hours, or very fast after a restart.
Maybe this is the way android should work. I was thinking there was a problem with my phone, but seeing similar behaviour with yours, it must be something related to the android system.
I'm on JB me1 and i haven't this battery dran problem. After the night i just lose 3-7% battery
When I have 100% and I off my phone and turn on battery go down to 50-60% immediately in one secund! It must by hardware foult...this is not normaly working android, for me

I thought that is not really a battery draining. But it just about battery calibrating. Your phone need to calibrate the battery. Thats the problem.

its normal to see 99% when unplugging from charger, 3%-10%(Max) drop on rebooting. Battery is usually inaccurate after charging, what I do is plug it in then reboot. then it displays the right value after unplugging, usually my battery status is really inaccurate but it returns to normal afterwards (it'll show charging icon even when unplugged and charge to 100 then stops and returns to real level). I don't believe in this calibrations and have found enough proof its useless, I think most xda users agree too. Try searching some threads.
