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 need help. My HTC Desire keeps shutting down automatically at 30% battery life. And when I power it back on, it stays on for a while then automatically shuts down again. The same happens when I havent fully charged it and its still in the charger.
It does the same with both my batteries.Is this a fault or a type of security feature? Is there a way around It?
definite fault - have you flashed it or is it the stock rom ?
either way, it's not a 'feature'
I'd be seriously pissed off if that was a security feature.
Are you rooted?

If you're rooted with ClockWork, go into advanced menu and reset battery data.
Seems to me that the info regarding battery usage, cycles etc has been corrupted.
Could be because you're changing batteries.
I might have experience similar issues. Last week my battery was approx 30% when my desire suddenly shut down.
After a while I was able to boot into Android but it immediatly shut down again because of the low battery.
If it happens again tomorrow, I'll try wiping battery stats.
Please report back if you find a solution.
Hello!
It is the same for my Desire. It also goes off with 20 or 30% power left.
I have a rooted device. I wiped battery statistics via recovery and as a result - now Desire shuts at 30% (but before it happened at 20%)
I am using Modaco r3.1-bravo-desire-modacocustomrom-withadditions-a2sd+
This is really weird.....
Any thoughts or recommendations?
Guys, which rom are you using in your devices?
Had no issues on r3.1 MoDaCo but I'm using my own ROM (check sig for link) now and haven't experienced a single problem with the battery.
wipe your battery data and fully charge your device from ... (dont know how to say on english,sorry ) - i mean, not by USB cable.

wall charger
Full charge with the device powered off.

Last week I wallcharged when the device was off and I was able to drain it down to 16%.
So it's good.

Thank you for advice! Will definitely try.
Any luck with this? I've ran juice plotter and watched my battery drain from 23% to 0 in 10 minutes.

Shutting down at higher than, say, 1-3%, means that either the battery has defective cells (not sure how likely that is here - only seen it on laptop batteries) or the meter isn't calibrated properly. Most of 'em recalibrate once they've hit empty, so if it's the latter, it should theoretically resolve itself. Anyone know if there's a possibility to recalibrate the meter on Android (full charge, full discharge and then full charge)?

That is really weird!
Once I charged Desire (when it was switched off) with the wall charger - I was able to work till 7%. I was happy and thought that the problem has been solved.
But I was too fast!!! Yesterday Desire switched off again at 27%.
Totally frustrated.....
Weird problem ain't it. I managed to charge up my phone to about 15% after it died and it slowly died like it would normally

I guess to rule out software you should clear the battery info. Do a full charge (some say with phone off), do a full discharge and then a full charge again.
A full charge-discharge-charge cycle should, at least in theory, make sure the software knows what's up.
And to be sure, use your battery in another Desire if possible. If that one shows the same behaviour with your battery (and obviously shouldn't have any troubles before) it must be something with the battery.
Or! Just start nagging at HTC and get yourself a new battery with some nice social engineering
on earlier ROMS(custom as well as stock) my desire used to shut down at 14-15%
but with insertcoin 1.14 its shutting down at 25-30%.....real pain int he ass
I have also calibrated the battery by emptying it and wall charging but no luck..
any solution guys?
why people dont think that this is a real problem im trying to search for a solution from more than 1 year but there is no permanent solution ,,,, many phones have this problem ,,, !!!!!!!!!!! very strange
Use usb connection with pc to charge your phone: it's long time but the best way
Try to delete battery stat from recovery also
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!

I never turn my phone off.... just charge it every night. Its my alarm anyway

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?
Sent from my HTC Vision
.. 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.
Sent from my HTC Desire using XDA App
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%.

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 ?
Guys. i did this.. battery calibration thingy hoping that it will boost my battery life but i think i messed it up. not it charges until 86% only and gets stuck there. and when it goes down normally to 1% and shuts down normally. I used the script from zepellinrox before this. Now, at 5% the script says it should read 36% so yeah.. sounds like im screwed. Any idea how to fix this? couldnt find anything on it because all the threads say that i need to charge it up to 100% to do a calibration and most of them mentioned that getting stuck at 95% and above is normal.
Get what I'm saying?
I've tried restarting my phone, wiping battery stats, wiping dalvik, recharging, turning it on without battery then putting it back in.. nothing helps. it's now saying 18% 3884 mV according to battery calibrator app.
did i just destroy my battery?
Anyone had the same issue before?
I was thinking maybe restoring from nandroid would help or flashing a new rom or a new kernel or just flashing stock rom would solve it but I'm not sure... Any help would be appreciated. Thanks,
sorry guys false alarm please delete this. fixed it

how do you fix it? I have a similar problem my battery shows 19% but its in 1%. any advice? thanks
You mean it shuts down after 19%? I just discharged it completely and charge it again. Try charging to phone to full, use battery calibrator app from market. 100% should be about 4200mv. Charge it up to the max, mine can only reach about 4190 max. Then hit calibrate and use normally until it completely discharge and charge it full again.
