[Q] phone showing wrong battery charge

hey guys,
i got a little problem with my sgs: it shows me that the battery charges itselfs if i don't use my phone for a little bit (for example: i play half an our lane splitter and battery goes to 23% then i leave it for an our in standby and when i come back it shows 28!)
I hope the screenshot might can help you.
P.S.: Sorry for my bad english

...

Did you also try battery calibration app from market?I don't know if it does anything else than clearing battery stats, but I think it's worth trying...root is needed though.

I have tried it with the app and with cwm. Both didnt help.
I think both do the same thing.
Sorry for bad english.

You can try to do a wipe battery stats in recovery after you have done a full charage.

..

Maybe just your battery is already death, try another battery if you have a possibility.

..

I have this issue too. I think it estimates battery and when it is left to idle it gets more accurate. I notice if I continue using it it still dies but idling saved battery..... could show battery percentage according to usage ? ( although I'm guessing here)

[Q] Battery draining very quickly after calibration

I was messing with my phone (rooting, testing out roms, etc.) and I decided I just wanted plain old stock. So I put it back to stock (official 2.3.5 gingerbread) and rooted it. Then I decided to calibrate the battery by using the Battery Calibration app in the Play Store.
Now my battery drains about 15% every hours in standby mode. Do I need to wait more time for the Battery calibration to take effect?

The calibration doesn't work on stock it only work on custom ROMs... kies calibrates the phone and reset the batterystats.bin so there should be something else killing your battery especially 3g...disable what ever you are not using rotation/data sync/bt/ ect.

It's still draining that fast on airplane mode.

"Calibrating" the battery is huge myth. It does absolutely nothing.
batterystats.bin is used to display what has been using your battery in about phone/battery use. That's it. Has nothing to do with calculating the remaining battery, or does not improve or decrease battery life in any way.
Furthermore it is reset EVERY TIME YOU CHARGE TO 100%

That's what I've read but it must do something, because since I ran that app and 'recalibrated' the battery, the battery dies in about 7 hours on stand-by. It would last me all day before I ran that app.
I did find one thing that was using battery on standby...my Beautiful Widgets Live Wallpaper. I set the wallpaper turned off the screen and after three hours I checked the battery use. I found that 'Display' was using the most at 50%. And during that time, it drained about 45%. I'll keep testing.

Oh yeah forgot live wall paper kill around 20% never use it so case close....

It looks like that's the culprit. I must've put on the live wallpaper sometime after 'recalibrating' and didn't remember. I'll let you know if I have anymore problems.

Galaxy S i9000 some unique battery problems

Hi guys i have a galaxy s phone and it's working really great, but now a days it shows me some weird battery problems...
ProblemNo:1.Some times my battery shows like 45% or like that and it goes up to 46 or 47% after a few minutes during discharge
2.Some times when i have about 55% then if i remove my battery and put it back and when i reboot it shows only 5%, this problem is very rare but it's occurred more than 2 times
3. when i am charging my phone it's reach up to 99% then it drop down to 98% then 99,100
These are my problems,i am using MIUI 2.4.20 ROM
what causing these problems is it my battery faulty or do i have a hardware problem
or is it the ROM
please any one help me.....

Have you tried wiping the battery stats in cwm?
Or, trying a battery calibration app from the play store? For example, Battery Calibration.

Problem number 1 occurred to me a few times it isn't a serious issue.
Problem 3 you need to wipe battery stats and calibrate your battery (play store has apps for that)
Sent from my GT-I9000

My guess is that using multiple batteries is playing havoc with your battery stats, but what the solution is I have no idea to be honest

i am using only one battery not multiple batteries

i don't think that battery stats file has anything to do with this problem, it's something else...
my worst fear is that is it my phone's any hardware part is faulty.....!!
Or guys is this problem occur if my battery is faulty....?
help me to sort out the problem............

I have this issue also.. I checked and my battery is on good health, really annoying but nothing I can't live with

I fond that if its at say 50% and I reboot and it drops to say 5% it takes ages to discharge that 5% so I guess it has the same charge just reading it wrong, if I leave it for a while without using it it will go back up

Battery life

Hi
I've been lurking these forums looking for this but haven't found anything quite like this. The P880 prides itself on great standby battery life but mine is draining more than my previous Motorola RAZR (not the maxx). It never lasts more than about 14-15 hours and that is when i do almost nothing. One, two calls a few messages with no wifi and data off. I have factory reset the phone a few times and whiped the cache. I've tried not installing any software when done and fully charging but still it drains. I'm on v10f but this was a problem before I updated as well.
My only thought is that the battery is flawed, but I don't want to wait 2 weeks for it in repairs if it isn't (the service here is slow and customer support is weak when it comes to this, here in Iceland)
I took screenshots of the drainage. 90% of that is me not using the phone at all. Is this normal? Should I ask for a new battery? The phone is about 3 weeks old btw.

What version are you on? 10f has seen lot of improvement in battery life. I dont have to use SetCPU anymore to get better battery and let it run on max 1.5ghz and still seeing very good battery life, despite heavy use.

Yeah I'm on 10f as well. I was wondering if maybe flashing the phone and try to reset it totally would help but I don't know if that'd be any different than just factory resetting?

This was taken at the same time as in the orriginal post. I only talked for a few minutes though. I have sync disabled all the time as well.
I have seen other imgs of the battery graph and when it's on standby the line hardly tilts downwards. This can't be normal right?

I'm going to charge him to 100% and leave him with nothing on all night and see how he handles it. What would normally happen? How much percent-drop would the battery have on an 7-8hour timespan?

Went to sleep with the phone at 94% and woke up with 69%. Everything was off. Sync, mobile data, wifi, backround data, location, gps, nfc, I even set it to 2g networks only. Now it says that the "phone" took 69% of that? I'm flabbergasted.

Same here man but didn't diseabled auto sync and broadcoast cell yet so I'm curious if I go sleep and wake up how much juice it took from my 4xHD. Something is sucking out the juice out of our phones.
The only thing that update did change with me is the heath it didn't get as hot as before but my battery is still eating a lot even when is standby.

Hey, I don't no if your phone is rooted or not?
Try deleting superuser, it helped my battery life. And also you should charge your phone more than 100% , that helped too for me.

Try to do a factory reset, the update didn't help me until I did a factory reset. Now my 4X HD only looses about 1-2% over night vid auto sync, before factory reset I lost about 30-40%.
Sent from my LG-P880 by Tapatalk 2

I use GO Power Master to auto switch to Alarm mode (only alarm, brightness 30%), and the phone eat less than 1% of battery for 6 hours. (firmware V10f)
I cannot see the attached images (don't know why) but I think you should check how long your phone is Awake, Screen On, Wifi and GPS On... then see which apps are cause the drainage.

Also, give the battery more recharge cycles. The battery life on first 2 cycles was catastrophic - for example it lost 4% just by rebooting, but after few days it stabilized to my ordinary each 2nd day charging cycle when turned off in the night. The biggest battery eater seems to be for me display brightness.

Batterylife with 10F is pretty good. Over night I dont lose any battery (data off) and during the day with autosync on only ~2 percent per hour. This is even better than the Samsung Galaxy S2 which I previously used. I did set CPU max speed to 1,1GHz with SetCPU.

Oh my! I think that worked! So the root was causing the drainage? I'd really like to have him rooted though. Is there any other way to avoid this?
I'm testing this out right now though. I will know if this was the problem in a few hours!

[Q] battery gauge problem

hello
after flashing a few roms, my battery gauge is messed up.
the things i noticed, when my ace turns off deu to low power. the gauge shows 0%.
but when my ace shuts it self down and i plug in the wall charger. the battery gauge shows me a percentage around 75%.
the things i have done to solve this problem is deleting battery stats by cwm and a calibration app nothing did solve the problem.
also i have let the battery drain to zero and then charge it up to 100 and let it drain to zero again. also that didnt solve my problem.
so i flashed back the stock rom by odin. also not solving the problem.
is ther another way to solve the problem

Get a new battery.:thumbup:

The problem is not with your battery. It's with the battery notifier in the ace. It works well for a time and then goes absolutely crazy. Whenever your battery gets low, about 10% for example, connect the charger and charge blindly for 3 hours. Don't worry about the 100% notification. Try your battery now. It should be fine now. But if you're using battery extender kernel, there's a bug in it that brings down the battery for 50% in a short time after using.

i`am on stock gingerbread, the phone is about two years old. i also noticed that when i turn of my phone and pull the battery out for about three minutes en then put it back in the percentage is higher. so i do think that the battery gauge is messed p but when i use a calibration app to solve it, it gets worse or doesnt change. when i use code *#*#4636#*#* the status of my battery is good. im thinking to buy a new battery but i doubt that it would solve my problem.

Calibration is all fake. Do as I said and you'll definitely witness the results.

Hi, I have the same problem with the ace of my wife. When I charge it, it says 100% after 10 min charging !
And when I use it not charging, it drops down ...
I try to let it charge longer, but is that sure that the battery continue charging even if the notifier indicates 100% ?
I'm on [ROM] CM7.2-DEMOCRACY FINAL EDITION .. is there also a kernel to change to help ?
Thanks for your answers, by default I will let it charge for 3h.
PS : is there an app to check the battery life ?

in dialer u must enter the code *#*#4636#*#* there will appear 4 tabs there is one for battery tap it and you wil see the health of youre battery.

Guys, forget about battery level notification, etc. Any app doing so would collect the info from the android itself. Just do as I said. Everything will be fine.

I've the same issue. I charged it for 3 hours, it's not fine, it goes to 50% in about 15 minutes, and when I reboot my Ace, it drop to 15% !
I noticed that when I turn it off and charge it, the green battery indicator is at 80%...
Any idea ?
I tried differents ROM such as CM10.1 CM10 CM9,PAC, same issue.

I bought my wife a new battery @2000mA and she lasts 2 days now, so the answer seems to be the battery-life ...

CM 9, 10.1,PAC consume battery like hell, but not that much also.
If there r such huge drops that too after charging the fone for 3 hrs then i guess there is a problem with the battery.

Yes I thing the battery is dead, it's slightly inflated...

I too have the crazy battery problem, but funny thing is if i were to ignore the indicator and just use it from a 3hr-full charge till it dies off, i could achieve 2.5hours of internet surfing (wifi not 3g). To me this is good enough, all calibration fixes do not work for me. Any suggestions?
PS: I have the system time problem too with S'perience Rom, Eg. when i shut down the phone at 1pm to remove the simcard, after booting up the phone the time shows 11am. This happened to me more than 5 times this week. I dono if it's the rom or the battery that gives this problem. I dono about how it was when running stock rom because this phone does not belong to me. Any help is much appreciated.

Try a full discharge and then plug your phone until it is fully charged, finally without unplug it boot into CWM and wipe battery stats, finally reboot and charge it until 100%
