Phone doesn't detect battery level correctly

One day i was found that my magic isn't charged fully - charging level is stuck at same % (say 66%) although charger was plugged in during all the night.
Beginning from this moment the phone doesn't detect battery level correctly and don't charging up to 100% nor when it is on nor when it is off. For example it can show me one value but after reboot shows differently another value (for example was 46% but after rebooting is 8%, or in some cases battery level can be even more, than before i performing reboot - say was 22% but after rebooting is 78%).
I'd tried wipe, erase system partition and re-flash rom, flash another roms - all without any luck. So i decided that my battery is died. But when i got a brand new battery (from another just bought magic), i got the same issue as in case of my battery. Also another magic works perfect with my battery.
It appears that problem in the phone itself? Anybody got the same issue?

Me too....

did you try wiping battery stats (from recovery)?
I'm not sure if this is supposed to done from a full or empty battery though

That is what i waa going to say, but I'm sure it doesnt matter what level your battery is when you do this aslong as it doesnt die during the process. Anyways you could have a faulty phone reading the levels wrong if changing roms and doing this doesnt work.

I found several similar cases on this forum but no one answer that actually explain what and why it happens.
In my case i got this issue after performing battery calibration procedure. Maybe is just coincidence, i don't know.

Yep, of course i tried do this from recovery and manually deleting battery stats file - both with no luck. Also during rom flashing battery stats also was erased.

Tried un-root my phone by flashing Android 1.5 from MT3G - issue isn't disappear. After a week maximum detected battery level is falling down and i can't get even 40% of charge. Now, two weeks later, maximum charging level is only few %. Damn it

Charge and battery life problems

Hey there i have a HTC Legend running cyanogenmod 7.0.2.The problem is that i can't charge my phone to 100% it usually charges to 65% and it drains very fast but i noticed that i stays on 3% for +- 8 hours with extensive use.I thought that my battery wasn't good anymore but yesterday i tried putting my battery in my friends htc legend and it showed 83% while it showed 13% on mine so i put the battery to charge on my friends phone till it charged to 100%(that means that the battery's still good)but when i reinserted the battery in my phone it showed 65% just like when i charge the battery in my phone.I thought that i could try calibrating my battery but the phone doesn't charge to 100%.I was running blay0's b0.8.4 rom before this cm7 rom and had the same issue.
Any suggestions how i can fix this.

turn off your phone, plug it all night long then restart in cwm recovery and do "wipe battery stats" ( or something like that in advanced)
restart and see

I have already tried that i have turned the phone off and left it to charge for two and a half days long without disconnecting the charger but the light still didn't turn green.This is really annoying cause the battery drains fast and when its less than 15% the orange light turns on which i don't like to see

I have the same problem with my Legend since I update from stock 2.1 to 2.2.Actualy because of this I root my Legend then i can calibrate it but nothink seams to help.After all night charging the led is still red and when i start it up it shows 75% and go down fast.(1 hour or so can bring it to 5% easily).After when i switch it off and take out battery for few second and put it back it come back to about 55%.actualy the same problem as you have.
I just live with it....i trayed every calibration method and app. and nothink helps.
On another forum one guy told me then it probably need to be recalibrated in factory because i dont have the right tools for it.
I dont think then HTC will do that for me specialy after i root it.
If you find solution please let as know.thanks

Then unroot it, install your carrier's firmware just the way it came with on the phone, and send it back. I would imagine it be hard for them to tell that you've rooted it.
Or just before you do so, check if the battery's still messing around before you send it back.

I have two battery's and the problem is the same with both of them.If is true then they can not understand i will give a tray...i think then this is the first think they will look it at just to tell me f**k you..hahaha

I' ve the same problem with stock legend 2.2. How can we do?help!

So this is what i tried i drained my battery completely till i had 1% of charge then i put it to charge while the phone was still on and it has been on charge for two days and i see that the phone has charged to 76% usually it would charge to 65% so maybe if i leave it for a couple of days on charge i could get a full 100% charge.So that is my last hope unless you guys find something else.
I will post back if it works for me

BTW couldn't it be a kernel problem??

All I know then the problem started when I update from 2.1 to 2.2 stock rom.so my theory is then when you flash new rom the process take some time and energy from battery and when the process is finish the system take current battery state as full which is not true because of used energy from flashing process.So maybe providing DC power with the same voltage as fully charged battery when flashing new rom may fix it.I maybe wrong but in theory it may work.what you think?

I have 2.2 since release date,and the problem is present since one month,after about 6 months 'hotspot mode' for home internet.i think is a battery problem (charge and navigate at same time for 2 hours for day)but this thread show that is a common problem!

i'm having the same kind of trouble for the past 2 months. no matter what i've tried nothing happenned. i'm running custom 2.2 , without rooting or so and charging level stops at 71-75%. drops down relatively quickly until 15% and easily can stay with 3% for over than 5 hours.... htc suggested to run a factory reset,but even this didn't help. if someone finds a solution it would be ...LEGEND...

The phone is actualy charging the battery correctly,i find that out with the multimeter.I measure the battery voltage after all night charge and even then in the phone it shows 75% and voltage 3.950 with multimether i find out then voltage of the battery is 4.220.So thats mean then phone is charging correctly just the indicator(software)doez not interpret it it right.Still is anoying to look at red led after 1-2hours of use.
I have S-ON so maybe even if the calibration app.say after i tray to calibrating then batterystats.bin is deleted it maybe not true becouse of S-ON.
Do you guys with this problem have S-OFF or S-ON?
Maybe is not related to S-OFF or S-ON but who knows...

Maybe if we charge the battery till its full and testing it like pirate81 said with a multimeter and then flash a new rom maybe that could fix it has anyone tried this??

I start to think then XDA developers forum is useless...i post my problem hier to get help from people(xda developers)which I think then they actualy know somethink about android but It seams to me then XDAdevelpers actualy dont care..end i am sorry for that....dissapointed.I see then this forum works on basic.."help your self"...where are you XDAdevelopers...we come to your forum because we need help from you...
I know you doing it for free so i should be happy for what i get but i was waiting a little bit more of interest....sorry i am just dissapointed.

Anyone find a solution?
Would it help if we went back to android 2.1

I allready trayed that..save your time...no changes.

Can't we just use someone elses battery stats file someone who's battery does charge to 100%

I have same problem for 6 months already and yes, it started when I upgraded from 2.1 to 2.2 and it's only getting worse. It was 95% maximum, then 75% then 65% and now it's 45%.
Changing battery or firmware (custom or official), wiping stats, factory resets or calibrating batteries does not help.
Now it dawned on me that I still heve 2 weeks of warranty left and I think I'll try official service.

Please let as know when you will get it back...if they change just rom and calibrating or you will get new phone.I am interestig if it is software or hardware issue.thanks

I had a similar problem with my ol prophet.
I let the phone deplete its battery and charge over and over again (4 times as I can remember) and it's solved.
But I don't think it's the same. People were doing something to raise battery life and health, I can't remember. Or a simple factory reset (or a wipe) could solve. Possibilities.

same with my wildfire tried 2 or 3 roms but stil not able to slove my problem it stuck around 70 to 90 % please help me out buddy ..

Try wiping battery stats using ClockWorkMod recovery (I believe AmonRa has this function as well).

thanks guys for replying
i have stock 2.2 froyo.. i guess i have to try factory reset.. but will try that draining and charging thing first ..
any other solutions

factory reset also did not work.. any other solution guys ??

{Q} Battery issue; please help

Hi, i bought tattoo from another user... to encounter a problem with battery, when i charge it-it never goes 100%, but charges to for an example 33%... then it instantly drops to 16-17% until it reaches to 1% (fast dropes)...but it stays like that for one or two days (like it has been charged to 100%). I did a factory reset-it dind't work (offical rom, not rooted). I first tought it was a rom problem it self... then i rooted my phone and flashed cm7 (wiped all 3 times)... and the problem still presists. I dont know what to do... i tried to put my batt. to another tattoo, and it works fine...also tried another charger, doesnt help... i dont know what to do. Please help....
Thanks.

Looks like a battery calibration problem, fully charge your battery, go to clockworkmod (if you use it, i dont know does this option exist in amon-ra), then go to advanced, wipe battery stats, after that do a full drain and then a full charge again

Yeah, I'm having the exact same problem.
I read that the problem would go away if you buy new battery for your phone. I, myself, tried re-calibrating battery but had no luck. With re-calibrated battery it looks like that battery is in a bit better shape than it was previously.

i had the same problem and i bought another battery and the problem wasn't yet solved .. but i think it got fixed by it self.
Try doing Wipe Battery state couple more times..

Try another battery to see how changes

Hi, I've the same problem, tried with factory reset, cm7, wipe battery stats, wipe dalvik cache, and no changes at all. The battery never charges to 100%, and it drops to 1% very fast. When I put that battery to another HTC Tattoo, it shows that the battery is fully charged.
Do you fixed this issue?

Battery problems

Hi everybody !
I have a problem with my note 4 since few days, my battery indicator shows 40 or 20% of battery left but it shutdown itself and reboot.
After that, it shows 0% of battery left and have to plug my phone.
I already tried to wipe caches and battery status with a root app but it does nothing :roll eyes:
My phone have 535 cycles of charge, maybe my battery is already dead ?
For info: i am on Kyubi 2.2 rom, but i've noticed the problem on COI3 Stock/unrooted.
Does anyone have a solution for me? Thank you in advance :good:

No solution, but same problem on 5.0.1. Mine dies at 15%

Search first, there are several thread already discussing about this problem.
It's because of your battery has degraded through time.

My problem seems to be resolved for the moment, i don't think my battery is dead yet...

Battery is faulty, please replace.
