My nexus s battery is not charging to 100 percent

I've had that problem with certain kernels I think. Dunno if that will help. Usually a full wipe and reflash fixes most if not all of my issues.

I had this problem with Trinity Kernel. Changing to Marmite solved the problem to me.
It is not an issue. The phone is designed to charge only up to 98% to further extend the battery life. You can try some kernels if you want a cosmetic fix.
It is called BLX and it is only to "look" like it is 100%, but it really isn't. Like @ej8989 it is just cosmetic. This is all done to keep the battery safe. Overcharging and undercharging is harmful to the battery.
If the kernel supports it:
echo 100 > /sys/class/misc/batterylifeextender/charging_limit

I switched to serendipity 5.10 from perception 10.4. I currently have speedmod and kp1. My problem is my battery. The very first time i flashed a rom I didn't do it on a full charge. I've tried the bump charge and deleting batterystats.bin file etc etc... Nothing helps. Could I have damaged the phone/battery for good? A full charge lasts about less than 8 hours with moderate usage. It was fully charged and I let it sit overnight off the charger and lost 12% by morning.

Um.. are you overclocking it? If you are that will kill your battery if your not tweaking your voltage settings.
I don't overclock my phone - so unfort I can't help you with under volt settings, etc.
If you think your battery was broken after flashing - you can test this theory. Flash back to stock - charge up the battery then run as normal and see if you get a normal usage then you know it's the ROM (*) and not your battery.
Actually no I haven't done anything with over or unclocking. I did try that before with stock and it was the same. And I did get another battery also so its the phone not the battery. I guess i just have to live with it

Hello,
Since I bought my cell (about 1 year ago) I've been experiencing low battery life. I've used different roms, tried about almost everything to decrease battery consumption (2g, no wi-fi, etc) but it still lasts about max 8h (moderate usage). While using continously it lasts max 2-3h. So is this normal, what could I possibly do about it or should I just buy a new battery?
Currently running Nova Hd RC 21-39 with Supernova pre RC-3 kernel.

No that's no where near normal. Could you get a screen shot the battery usage ?

Not sure if you ment those stats, just tell me if it are not the right stats.
Translation:

Other stats are:
Screen - 92% (on automatic though) Wi-fi - 7%
Mobile stand-by - 3%
Yes, it makes 102% kinda weird ^^

don't sorry about screen percentage, its heaps inaccurate.
Could you install system panel from the market and tell me what the cpu's are doing on idle?

Nothing really special, it varies tho sometimes it goes to max instantly and drops back within 2s

same issue here..
running nova hd RC22-41..
I'm pretty sure the battery if screwed. You can pick one up off eBay for a steal.

Your cpu is at 50% all the time, how is that nothing special?
Install os monitor and check whats using the cpu.

Looked at OS monitor and only thing that consumed cpu is android system (5%) and system (2%)

I'm running CM7.2 RC1
Worked fine for a while and now th phone looses 10% per hour (idle). Checked OS monitor and System panel but there is nothing eating CPU or something that shouldn't run.
Only thing that changed between the two phone states (fine / annoying as hell) is some experimenting with GetRIL. So I re-installed the RIL (v20l) that worked fine before but it didn't help.
Also I have two batteries. The original LG and the Andida, both give crappy results. Think I'm going to try to go back to the stock ROM, see if it helps.
i just did that. having two batteries will probably confuse the calibration unless u calibrated them the same way. either way, from what im guessing, not fully discharging the batt will mess the readings as 1 constant battery ?
According to my earlier measurements the Andida is also about 1500 mAh in real life. So it shouldn't differ much. From what I read clearing the battery stats doesn't do much, said some Google developer. I'm back to v20r now and it looks much better.
40% in 7 hours, before it was 10% per hour idle.
Today it was even better, ~30% in 8 hours. This looks more like I was used to.

Im using Dark Knight 5.5 and SemaphoreICS 1.1.1..What should i do?? The battery just keeps getting used up even if its kept idle for a long time
You can try removing systems app or moving to another ROM
My Android OS only use 4 percents of battery
Sent from my GT-I9000 using Tapatalk 2
use AOKP or Slim ICS and see how that takes a 180 degree
CM9 is the best one. no battery drain.
It probably has nothing to do with your rom, try better battery stats from market, read the getting started guide, and check for wakelocks.

id say change a kernel. had a similar issue with glitch, moved to devil and problem solved.
use battery calibration

Resetting statistics does nothing for the actual battery life.

I've noticed that my phone spends much battery with the screen off, i think its te Modem what do you think?
Im on cm9 nightlies with semaphore kernel.
this was with almost all the time screen off and 2G, if its fault of the modem recommend me a battery saver modem.

You can instal the Devil kernel and activate "Deep idle"
Also try JuiceDefender
Sorry Bit i use both deep idle and also juice defender, i really dont know what to do!

I'm going to say it's the kernel as I'm running the standard one that comes with Cyanogenmod 9 and I don't have this issue. Actually, my battery is above average.
There's a big issue with i9000's running hot and having high drain at the moment. I'm not sure what has caused it on mine. It seemed to happen after I upgraded to CM9 but I have flashed back to 3 different varieties of stock ROM/kernel and same story. Gets really really warm when under load and battery drains at the rate of around 20% an hour when the screen is off, phone is in airplane mode and NOTHING is running (i.e. in deep sleep).
At a real loss as to what to do about it, I've seen a thread about 500 posts long on the official Android forums with i9000 and i9100 users all expressing their frustration over this.
In your battery stats what is showing high drain? Also instal better battery stats and run it for a while to drill down what is causing problem

Hey, appreciate you are well intentioned but have been through all possible diagnostic steps and all documentation/suggestions I can find online. I am an experienced IT pro and have tried EVERYTHING that has been suggested ANYWHERE by ANYONE and there is no fix.
Screen is showing the most, followed by MediaServer then Apollo player. Problem is the battery drains when all those things are killed (i.e nothing is running phone is in deep sleep). This happens overnight when nothing is runnning at all. The battery stats do not change. The processor does not show anything as being used.
Many people have already been through the diagnostic steps and there is simply no answer.
Refer this thread:
http://forum.xda-developers.com/showthread.php?t=1635614
There is a reported bug on the official android site as well but I'm on my work PC and don't have my history from home to drag it up again.
Basically symptoms are
- Battery drains exceedingly quickly ~15% when idling and 25% per hour when in use.
- All diagnostic tools show nothing running or using your battery or CPU
- Phone is warmer than usual in any state (i.e. idling/charging/under load)
- Most folk I've seen with the issue have flashed to CM9 at some point but that is not a consistent truth.
Another screenshot that shows that the mobile standby consumes almost the same of screen

In your first post, i saw your "señal de red móvil", is very poor. Have one or two little line green ( best signal ).
As is the signal coverage where you are? The signal is good or poor?
and when you get with wi-fi on, the battery drains very fast.
Sorry for my poor english.
its poor man, thats why i want a battery saver modem, and the wifi battery drain its horrible, please help me!

But JVU its a GB modem, my CWM doesnt let me install other modems that are not rom ICS.

Did you have this problem from the beggining? I am using Dark Knight 3 ics, and for many months everything was okay. One day, i had battery drain. Even after a reboot, the drain was there. I reinstalled and it works fine again
guys, now i have a almost one full day with normal use, i dont know if i can get better results or whatever, but im happy with this result, i've done it downgrading to GB and i'm happy with it, but i would prefer to stay in ICS, but well im not bad with GB.
Hey guys I get good battery when the screen is off. But whenever I use it, it seems like it drops pretty rapidly.

Depends on what you did during that period.. If the processor was running at MAX frequency the entire time, yes thus might be normal.. Also as I notice from the screenshot, the screen is always in in that time frame.. So you deduce from this

No. It's broken. You should send it to me.
Hi,
Thats an abnormal drain. Try restarting your phone and seeing if the problem persists. Also note that the ROM you are using is still under testing and not a finished product so might experience some difficulties. Consider shifting to a more stable ROM if problem persists.
Having said that, battery drain will depend quite a lot on what apps you have running in the background and your settings.
Best way to analyse the situation is by installing an app called 'Better battery stats'. Its by a XDA member and if i'm not mistaken he offers it on XDA as free download. Try to see what is causing partial wakelocks and kernel wakelocks (your phone should be on deep sleep mode for the majority of time). Try to see what MHz is your processor running at (it shouldnt be in the 1400 range for too long unless you are playing some heavy duty games)
Also try to search for threads on 'wakelocks' on XDA to get more details on this subject.
I have experienced close to 10% drop in 1.5 hr in stock ROMs and around 15% in five hours on CleanNote ROM in idle states with lots of background apps disabled.
