do you people not search?? it been talked about for weeks this, when the desire reaches 100% it starts discharging to 90% before it starts charging again, even tho the batt says 100% so its random between 100 - 90 % when you unplug your phone, you wont know the correct charge level till the battery polls again 2-3 mins later

Of course I search! It's all I do! But iv charged my phone overnight for 10th hours plus so there is plenty of time to discharge to 90 percent or so then back to 100 percent but its just not happening.
Instead it just drops down and stays down.

it dosent do it just once, every time the fone gets to 100% it starts discarging!! the process is called exercising the battery btw i charge my fone with the power off and dont have this problem, but have noticed it when charging with power on

Ah i see. Just turned my phone off when it got to green when the phone was turned on then turned it off and it topped itself back up to green and now its still on 100 percent after half an hour.
Thanks for your help!

HTC Desire - battery at ~90% after plugging out?

Hello anyone! I have a strange issue with the battery of my HTC Desire. It is an original AMOLED type. I'm using Leedroid v2.0a and also wiped my battery stats.
The phone lasts 48h if I use it normally.
But I have an issue: when I unplug my phone in the morning it shows ~90% battery juice. Somedays I also had 88%. It differs from day to day. So also 95% is possible. I plugged in the phone at night, so the whole night the phone can power up till the morning.
Can anyone say why this happen?

It is a known bug, and you should use the search feature I believe you have to charge it fully, wipe battery stats, and charge it from that. Could be wrong, but check Q&A or the Roms thread

mine is original froyo & untouched Desire and it is same here. If I turn 3G data off (also wifi and bt are kept off as well) then i can see 100%, otherwise it is abt 90 as in your case.

How to calibrate battery on g2?

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

[Q] Desire turns off at 10%

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%.

Battery status issues

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
