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.

Battery question

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

[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%.

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

Problem with battery.

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.
