[Q] desire battery not charging

Ok so I installed a Gingerbread ROM (Oxygen's) which was great, but then after a few moments my Desire is stuck at charging at 50%. I flashed a different ROM but it made no difference. It has been 3 hours since I plugged it in and it is still at 50% Any ideas?

Try to wipe battery stats in CWM. If it doesn't work, try another battery and see if the problem stays.

I have the same problem! my bro baught a new htc desire...he fully charge it but the battery doesn't charge above 50%. Also no matter for how long you leave it charging the led never becomes green. Lucky for him i have the same phone...rooted i put his battery in mine, wiped battery stats and now i put it charging...i'll let you know what will happen...
P.S.: HIS desire With MY battery shows AND charging my battery to 100%. So i think the battery is dead and i will send it back....
anyway i will let you know what happens!

Update : New battery using the GUARANTEE...and firmware update...the battery was dead...

[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%.

Hope it helps!

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?

Should I calibrate my battery?

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 ?

Battery problem

Hello,
for a past few weeks I have a battery problem At first my phone was shutting down at 30-35%, today at 50% :O :O
I know everything about battery calibration, I did it at changing the ROM and did it last week when my phone was fully charged, in recovery. Battery monitor widget says that capacity is 790mAh after two cycles of charging.
I also create new battery in Battery monitor widget and it says that capacity is 1480mAh :/
You can see that now my battery is at 14% with 4123mV, that is not normal
Can it be that my battery is dead?
Does somebody has other method how to calibrate my battery?
Thank you very much

I can see that you use Sense rom so jump at Droidzone site and download some of the kernels with full battery calibration (I think it's #22 and up), flash it and that would solve the problem.

Or flash an AOSP rom and go to the nexus one development thread to find the battery calibration thread and follow those instructions.

[Q] New battery problems

Hi guys
recently i bought new battery because my old one used to jump
from 70% to 100% and had really bad battery life.
i replaced the battery and calibrated it and i noticed that the 20% from 100% to 80% goes down realy fast
should i recaibrate the battery?
what should i do? thanks!

It depends on the rom u r using.
All roms except stock based roms have this problem.

Im using aosp by maclaw studios
the weird thing is that the 70% acts like it 100% and im having really good battery life
from 70%

Its a problem in sumsung charge system.
In custom roms when u full charge battery it is about 80 % charged.

I think you should charge it when the phone is turned off. I noticed that my phone tells me it is "Charged" when it is turned on. However the actual percentage in Go Power Master is 80%.
Sent from my GT-Xperia S using xda app-developers app

so it has nothing to do with the battery quality and the battery calibration?
the problem will not appear in the stock rom?

Thats if needed. To check if the battery is fully charged, try these step.
1. Charge the when it is running until it says "Charged".
2. Turn off the phone and keep the charger plugged in.
3. The battery image will appear. If it is not full, wait till it full. When it shows 100% then it is fully charged.
Note that powering up the phone takes some significant amount of battery. If the battery is still draining fast. Calibrate may be needed.

enchanced rom shows 100 percent but still shows charging. So I guess it fully charges

Well the battery level seems to be jumping unusually from time to time . What i do is i wipe the battery stats from cwm , i leave it over night to fully charge without doing anything to it , calibrate the battery with `battery calibration` from playstore , full discharge and full charge again . I do this after each rom that i flash and it seems to do good and seems to point the right amount. Anyway the charge lasts as i hope it lasts , from 1 day if i do stuff with it like some wifi , some messaging , many minutes of calls .... to about 3 days if i do only calls. Cheers
