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!!!!
1300
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

Everytime my phone reaches 10%, the phone will shut down itself and it won't turn on again.
i have tried bump charging and calibrating the battery but still without success... anyone got any soulutions other then buying a new battery?
thanks.
Try this: fully charge the phone then let the battery drain completely, until the phone shuts down. Plug the phone into the wall charger, let it charge for a minute or so then turn the phone on while still plugged into the charger and let it charge completely. After a full (100%) charge, the battery indicator should be precise.
I've noticed that if i restart the phone of plug it in after charging, the battery indicator will show an extra 10%, so that's the main reason for the shutdown at or a little below 10%.
This operation should be repeated once a month, just to keep the battery and the battery stats fresh.
Don't wipe battery stats and don't try any other calibration tweaks. They might damage the battery. There are some people here complaining about that.
If the phone still shuts down at 10% after the above-indicated trick, then your battery might be old and in need of replacing, but i wouldn't replace it just because of a 10% indicator error if it can still hold a proper charge.
I have the same problem. I also calibrated my batterie and everything but it still turns off at ~10%.
But since I know that, it's not really a problem
Its always turned off at ~15% for me. I accepted that this was normal. I've seen a lot of posts around but no one seems to of found a proper solution. I actually doubt that there is a proper solution to this.
Punched in..
snq's kernel? I take it is normal with it as none of the GB sense rom managed to come even near the 1-2%. A bug with the kernel probably.
Flashed Oxygen last week - bam, phone turns off at 1%. No calibration was needed even .
Every time this happens to me I charge it 100% then I reset battery stats. Then let it discharge threw normal use then give it a proper charge, plugged into wall charger, not PC.....! And once its 100% ignore green light check it says 100% on the top bar then I unplug. Its normally always sorted then. But I have had to repeat twice in the past.
I also agree about kernal, often after updates it goes bonkers, and I'm on miui, lots of updates

Mine also used to turn off at ~14%. After using a battery calibrator, i could push it down to 7%. However, on the other "side" of the scale, it goes down qute quickly from 100% to ~92%. All this on GV2.8, and the unofficial ManU kernel 2.1.1.

Just wipe battery stats in recovery after full discharge if you changed ROM, and then let it charge to 100%.
Used the battery calibrator app (for nexus one) with detailed instructions. Now batt lifeis awesome, turns off at 3%.

I had the same issue on my stock Telstra branded rom. Since changing to cyanogenmod it hasn't happened since.

Did the thread move or die, or is the link just wrong?
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 I have a question about how I can reset my battery. I just flashed a new rom and my battery was around 70 ish percent, so I made another backup file of my new rom. After I completed the backup and renooted my phone the battery life showed itsef at 100% ans sees to die really fast. Is there anyway to return it to normal?

Charge to phone to 100%, boot into recovery, wipe battery stats, reboot into the phone. Use the phone til it completely dies, i.e. manually power off, then charge it back to 100%. If you undervolting or using other mods and your charging led blinks, its okay, it'll do that for a minute and turn solid. Again, charge it to 100% and you'll be good.
Only wipe battery stats when u are at 100% charge.

Hi all. Having trouble calibrating my battery. I even went as far as to buying Battery Monitor Widget Pro. But to no avail. When I unplug at 100%, my bat drops about 15 in less than an hour. After that it seems to use up the battery normally. At 20% it goes to power savings mode, turning off some stuff like wifi, etc... But then, at around 18,it shuts down unexpectedly and when I power back on and get into the OS, it says I have 0% and powers back off.
The problem is I don't know how to properly calibrate the battery. Most softwares I have tried only seem to make matters worse. Could anyone please help me out? I'd really appreciate it.

Fully charge, fully discharge, wipe battery stats in recovery, fully charge in powered off mode.. A few cycles ought to be enough.
Will try. Thanks!

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
