I got a G2 and the battery keeps saying it at 15% or less all the time. The odd thing is I get a full day on each charge and can get about 4 hrs talk time on a charge. I change battery and also change chargers thinking something was up.I also power it off and charge it over night and it never got above 30%. any idea on how to fix this. I flash many different roms to it over the pass yr right now I'm on mimicry 1.3.1 but I used to have CM 7.1-7.2 and had the same issue. I just annoying getting the prompt saying your below 15% all the time and not know what my true charge is at since it will sit at 10% for 6 hrs.

Do I do this from full charge or completely dead?
won't really matter, just wipe them, charge full, discharge to around 20, full charge again (like over night charges) maybe wipe stats again and repeat

So guys how do you guys calibrate your batteries? I have pershoot kernel and I saw some people that their battery life is going up to 26 hours. I wipe my battery stats and my battery still drains 10% less than an hour. So anyone can give me some ideas how to do it? O and I use profiles in setcpu too,such as screen off battery and charging/full.

Run battery until phone shuts off. Turn phone on and play with it till battery dies and phone shuts off. Turn phone on again. Till battery dies. Repeat. Repeatu until it doesn't boot again. Plug phone into outlet (not laptop)
Don't bother the phone till the light is green.
let it charge for a few more hours after ut turns green. the g2 gives a green light not onl at 100 but between 90-100. let it charge until green then unplug and plug it back in to charge for another hour or so
After you do all that the batery will apear to drain faster but will stay red longer untill new battery data is built up to give acurate estimates.

How does one have the phone "off-off" when you have Clockwork Recovery installed? It turns on into CWR whenever the phone is "off" as soon as you plug it in.
Thanks!

Sorry, but right now you can't. It's a problem with Clockwork. If it really bothers you, you can always flash the stock recovery back again.
i did complete battery drains till phone cant power on than i charge a little delete battery stats in recovery drain again and than charge overnight. im at 11 1/2 hours with 74% left.

Are you using the stock batt or the CHichi's?
So I'm in the process of doing this....Right now I'm sitting on 27% after 6 hours. SO I guess it's normal that it drains much quicker after you reset the stats?
How do you "go into recovery and wipe battery stats"?
Are you rooted w/ clockworkmod recovery?.....rom manager?

.. No. Just have a temp root installed.
Well, I did just what you all did and now I get 42 days >=3 ha beat that!!!!

I find it hard to believe any of you are actually getting more 10 hours
unless of course the only thing you do is leave in standby and only text and barely any web or anything
1300 mAh is not alot
Hi peeps, any ideas on a battery problem I have having?. I plug my phone in at night and sometimes when I get up its only got upto around 85 to 90%, other times it hits 100% but then drops around 10% within about 20 mins. This only started about two weeks ago and I haven't done anything different with it.

Try the Battery reset procedure:
- Turn on phone;
- Charge to 100%;
- Turn off;
- Charge again to 100% (untill LED turns green);
- Turn on in recovery mode,
- Wipe battery;
- Reboot normally.
EDIT: This procedure mast be executed every time you flash a firmware.
What aledeago said, plus: the battery charges to full, then the charger switches off and it discharges again for a while before starting to charge again. This means that when you unplug it, it may not actually be fully charged if you catch it at the end of a discharge cycle.

Don't do that battery calibration thing but get custom rom with battery fix instead.

only the newer ROMs only really have the Problems Like the oxygen rom work perfectly with out the need of the calibration
Lately my phone will go through a massive drain until it hits around 55% then it will drain normally. I have not changed anything since this started. Any suggestions? I'm thinking I may need to calibrate my battery.

That sounds like a good idea for your situation.

Thanks for your input. I want to wait a few days before I do it. So it will give it time to see if that really is the problem. This only happened yesterday and today so maybe tomorrow will be better. Besides the only time I really have to do it is later this week.

How does one calibrate a battery? Is this the same thing as "conditioning?"

You charge your battery to 100%, wipe batterystats.bin, then run the battery down to 0%, then charge uninterrupted back up to 100%
Battery Calibration does it help ?
I have a similar situation and i followed the battery re-calibration method too but still didnt help.
Situation - The battery would charge till 88% but will show its fully charged. Recently put Vivokat so now its even more prominent. Every reboot drops the battery by steps, like i would reboot and the battery would go from 80 to 65 just like that, no gradual decline or anything. And even after a full charge (the green light indicator is on) still the battery would continue charging.
Tried - I tried resetting the batterystats.bin file as suggested, fully charged till 100% then removed batterystats.bin file then allowed to discharge all the way then charged continuously till 100%. No outcome
Anything else that can be done ?
Hello all,
Before some days I came back to GB from ICS and my "Android System" drains much battery. I installed mexdroid and I changed to elitemod to see if it is mexdroid's problem, but I got the same problem with elitemod. (After 4~ hours discharging with 2-3 calls and 15 minutes play game only, I got 60% battery.) Does anyone know what is going on? Thank you.

Well, you could order a new battery for next to nothing and see if that helps. If not, try flashing a new kernel. I had a battery drain issue on a gb rom before i went to ics. I have had amazing battery life with ics.

Remember that every time you flash a new ROM, you need to do a couple battery cycles in order for the battery meter to recalibrate. Charge the phone to 100% (leave it on the charger for a while to make sure its really full) then use normally until about 10 or 20% (don't drain to zero, as this is not good for Li ion batteries). Repeat a couple times. Your battery meter is not accurate until you do this.
Thank you I will try this and I will report back to tell you if the problem exists
I usually let the battery drain until its almost dead before charging right after flashing a rom.
Yes you should definitely charge to 100 and let it drain to dead. That will calibrate it. Then just charge it back up.

Woww that's a lot ..... I think the problem is from the battery because I used to have a phone which used to go from 10% to 100% in 20 min ....so you may have to change your battery because the charger isn't related(I think )

Wait for other answers ... IN 20 MIN YOUR PHONE IS FULLY CHARGED FROM 10% TO 100% ?? :laugh:
Yes,that's a lie !(in my opinion)
Try this:
Try to use the battery till the shutdown point.
let it switch off.
charge the phone untill the light turns green (100%)
Boot into recovery and wipe battery stats
now reboot.
Maybe that'll help.
Normally i guess it takes some 1.5 - 2 hours to charge using HTC charger. I'm not quite sure as I never noticed this before lol.
Also try to charge your phone when it reaches below 20% only and until it's 100% in one go, I've heard it gives a little boost to life by saving a recharge cycle and also it charges much efficiently.
