[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.

[Q] Battery worn out?

Hello,
My desire, after:
an inability to restore nandroid backup
a possible corrupted sd card
a usb brick and inability to mount some nand partitions
and finally succeeding in fixing it, now using/running:
2.29.405.5 stock rooted rom
a new sd card (samsung 16GB class 6)
clockworkmod 2.5.0.7
s-off
seems that has battery issues. When it reaches below 30%, it drains a lot faster. In example few minutes ago, the battery was below 30% level and after sending a couple of sms messages the phone, without the "Connect the charger" indication shut down. Not even the battery icon was red.
What should I do?
After flashing the above ROM I ran an app called battery calibration (could this be the culprit?).
I haven't experienced such problems before the whole mess mentioned above.
Thank you for your time.

Well, it seems to me like a "classic" battery meter calibration issue.

In order to calibrate the battery meter - FYI the battery itself cannot be calibrated, as Li-Ion batteries have a very low memory compared to old Ni-Cd etc. batteries - you have to go through the following procedure:
1) charge the battery to 100%;
2) let the battery discharge until the phone shuts itself down;
3) plug the wall charger into the phone, boot the phone up then charge the battery to 100% without interruptions.
If the above procedure does not yield the expected results, you can try fully charging the phone (LED showing green) with it completely turned off (after completely draining it). Again, the charging procedure should not be interrupted.
Source: personal experience - had to do this twice after installing new ROMs, as the phone was shutting down at ~14% (working like a charm now).
Regarding the matter of battery wear because of complete discharges, Li-Ion batteries do indeed have a lower cycle count than old-school batteries, but the standard charge/discharge number a Li-Ion battery can take is ~350, so you can't damage the battery pack by doing a full cycle per month (required to keep the battery meter accurate).
Good luck!

Did this work you mate? I have the same issue with my year old batter now... the phone shuts down @ 40% without any warning... and when I charge it, it starts from 0% and as soon as it hits the 58% mark, it jumps to 100% by itself... and i cant seem to figure out what the hell could I do to fix it... I tried calibrating the battery using the awesome method described here http://forum.cyanogenmod.com/topic/11823-battery-calibration-thread 3 times and nothing changed...

bump bump.. i really need help on this guys... :/

Weird that after calibration you still get that kind of issues, does this only happen on your current ROM? I have the latest CM in my desire and everything works just fine... Maybe try another ROM if calibration doesn't work to see if it's a hardware or software issue

i actually had issues with MIUI first.. the phone randomly shut down by itself but when i turned it back on, it was perfect... then i switched back to Oxygen and while everything was fine, suddenly one day the phone died at 40% :S and from that day on the phone charges to 58% and then instantly jumps to 100%... and as soon as it gets to 40% it shuts down itself... i guess i need a new battery but i wanted to see wether i can fix this one somehow so i can use it till the new one arrives...

phone turning off at 20% is fine mate because thats the battery guards against any damage
most of the phones ( smart phones) switch off at 20% as going lower can damage the System .

It shouldnt normally..It's supposed to work fine upto 5%

Have a look at this, it worked for me (but you need a compatible kernel, most AOSP are so)

Xperia Arc Battery Issue (Official ICS ROM)

From the past one month or so I am having this weird issue with my phone's battery. The battery drops straight from 20% to 1% and the phone switches off. This last time, I connected the charger before the phone switched off ( a matter of few seconds ) and the battery jumped straight to 21%. Is my battery terminally damaged or is it a software issue? I have attached a screenshot of the battery discharge graph available in settings menu.
Also, I faced the insufficient memory problem and I have repaired the phone about 2 months back using PC companion to ICS 4.0.4. I have been using the phone for about 15 months as of today.
Thanks.

hmmm maybe you charge your phone from pc? if you do this the battery will never get fully charged really...that i can say from my personal experiance.
By the way just charge the phone as much you can also let it charge on 100% and reboot it(battery lvl must go lower than 100) do this till you get a reboot with 100%...
If those do not help your battery is damaged you maybe have banding issues,3g/wrong baseband,forground apps? maybe a combo of all this.

Had the same issue, cured after repairing on SEUS.

Quite a fluctuate on the graph.

Maybe try to recalibrate battery!

Same issue, on mk16a. The battery is weird, if I leave CWM running it last for more than one hour, but androids jumps from 20% 1% or 0% suddenly. Also when booting again (after the shutdown) it's reports 20% but again it drops...
I'm on CM10 but i think this happens also on stock ICS.
Battery calibration don't work...tested it 2 times
Any hints?

[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

Battery drains in like 10 minutes

I mean, if I don't use my phone it can last for 2 days, even more, but if I run, for example, a stopwatch for 10 or 15 minutes it drains 80%.
Or, if I'm playing any game... I play it for 10 minutes and I get the notification to put my phone on charging. And in next 2 or 3 minutes the phone turns off by itself.
I tried to charge it to 100%, calibrate, wipe battery stats, still nothing.
Any thoughts on how to fix this, or i need to find a new battery?
Edit: I tried to change the ROM aswell, but nothing.

I had the same problems and I think it's worth buying a new battery. My phone powered off 5 minutes after it was fully charged and no battery wiping or whatever helped. Then I bought a battery for 6 € and now it lasts for ages.

I actually don't even know where to buy a new battery in my country.
I gotta ask somebody.
Edit: Will Ace's battery work on our Gio, I can find Ace's battery? I think it will work.
