I have a new battery on my phone. Its working perfect. I had to change because my old battery was swollen and died at 80 percent.
So recently I noticed that as my phone is charging and me doing small tasks on it the percentage of the battery goes down instead of up. Ive ran a battery tester and i get -155 mA going into my phone. So it discharges. I connected my charger to different plugs and I use the stock cable. I have a replacement cable as well. I know my charger is good as it works great on all of my other devices. What could be wrong?
It charges when I leave it. But As im a busy person I need to use it even when its charging. Thanks
Edit: When I dont use it it gets 500 - 700 mA and when used while charging (not used in heavy gaming just a internet or facebook/youtube app) -155 - -500 mA
1.turn off ur phone and charge
2. When its charged to 100% go to cwm recovery and delete the battery stats.
3. Calibrate battery using any app.

No! Deleting battery stats does nothing except clear usage data.

Hello. Just do a manual calibration.
Envoyé depuis mon N7000
The same thing is happening with me and I know it's annoying as hell..
Try to calibrate the battery. If it didn't work.. and since the battery is new as you say, maybe just maybe the charger needs to be changed, maybe it's not powerful enough for this specific phone and battery.
I found that all I needed is a better cable as the currentnone was broken. Now its all okay. Thanks

The last couple of days I've got a weird problem. When my battery is fully charged everything seems okay and it drains in normal speed (compared to stock).
But when my phone runs out off battery and i start to charge in the beginning everything seems fine.
But suddenly it can go from 75 to 100% in 1 minute.When i look at the stats in MIUI ROM it seems like it's not at same height as it was the last day of 100%. Maybe only 80%.
Sorry for my bad English, but i hope it makes sense.
I've wiped battery stats in CWM. But is it possible that the phone actually is only 80% charged, even though the indicator shows 100% after wipe?
Because if the ROM think the battery is charged and wipe stats it will afterwards only charge to that point and the battery maximum will decrease over days?
If that's possible, how do i full charge the battery? Just leave it in the charger or?
I hope you can understand what I mean.
Thanks in advance
Hello
Does your phone charge to fx 75% and after that doesnt get higher until after you restart the phone?

Yes excactly. But the numbers differs.
Today it charged to 100% though.
Got the same problem?
Sent from my Optimus 2X using XDA App
have you try calibrate your batt again
yes my friend have this problem too, maybe there is software bug
After flashing Celebration HD 2.0.1b I first used Battery Calibration from market to wipe battery stats. Afterwards the battery indicator problems started.
Yesterday i decided to wipe battery stats manually in CWM and drain to phone to 2% before charging, and afterwards I was able to fully charge the phone.
So maybe the bug in is Battery Calibration app?
I decided to install Juice Plotter to monitor the battery and compare it to one build in in MIUI. Just to get some more data.
Hello again
Yes i had the same problem as you, with my previosly 2 lg optimus 2x, and returned them because of the problem you mentioned. I am on the third op2x and luckily this work good
So if i were in your position i would try to go to the dealer and shift the phone with another lg optimus 2x.
Best regards

The user said that he started to have problem after a new rom and wiping battery stats, changing phone for that is not the smartest move at all. Is like changing phone because your rom doesn't work.
I have a similar problem, after you wipe battery stats you don't have a reliable indicator, for me the phone took 3 hours to get from 99 to 100%.
I also noticed that my miui ( 1.8.5 same for 1.7.29) doesn't update battery stats when the screen is off so all those plotter don't work, and i think this messes up with the battery indicator (I guess the phone doesn't have enough data to make a decent estimate)
I think is miui + wipe battery stats that can be problematic
I know that but i am just saying that i also had the same problem with the stock rom.
Best regards

How old is the battery? How many cycles does it have?
I know from laptop Li-Ion batteries that the voltage vs. capacity is not linear.
When discharging, the voltage will steadily drop to a "wear-level" where it will jump to an almost depleted level. When charging, this "wear-level" will be at the top.
Why I am telling this? Because if this mapping is kept in SW and you wiped it, Android needs to relearn it again. So at 1st complete charging/discharging you would see a % sudden drop/raise, but at the next cycles it would be linear with time (although the total time will be smaller than a new battery).
When laptop/phone battery tips talk about calibration, it is so whoever monitors the voltage (circuit in battery or SW) to know were the wear drop will be, so your estimates to be better.
As an example, I had a very old Thinkpad that did not have any calibration, and it would discharge to about 40% and drop to 5% within seconds. But when charging, it would raise steadily to 70% (from that 5%) but 70% to 95% in seconds. After years of use, that percentage gap would just increase (40-5 got 60-5, 70-5 on discharging).
PS: my current Thinkpad has 4 years and the battery capacity is 49% with 150 cycles. But this one has a nice feature where if the battery was above a certain percentage, plugging AC would not charge it (and thus save a few cycles). I used it set at 70%.
PS: LiIon batteries have cycle count, heat and time as main enemies. Also don't like prolonged (think storage) low charge.

I have when i turn off my fhone and i charge it it shows a battery icon whit an error in it ics lgp990 please help i dont no what tho do
im running a stock bionic and just need to know where to go to clear battery stats. phone says 100 pct but after a while of using it goes to 70 pct or so and turns off. when i plug in the charger it says 5 pct battery. after 20 mins or so charging it says charge complete.
This sounds like there's more of a chance that you've got a bad battery than a corrupted battery stats file. I have a friend with a Droid2 that was behaving exactly like that until he replaced the battery.
Should you still want to recalibrate, this is your best bet:
https://play.google.com/store/apps/details?id=com.nema.batterycalibration
any program for non rooted phone. thought there would be a setting in the recovery
Nope. Id take it in to verizon and tell them the battery is bad
Sent from my DROID BIONIC using Tapatalk 2
You don't need any 3rd party apps to recalibrate your battery. Simply let it drain completely (so that the phone powers itself off). Then place it on the charger and allow it to charge completely, uninterrupted.
If this does not fix the problem, then as others have indicated, you most likely have a bad battery. If you take the battery out and notice it is swollen or bulged, it is certainly defective.
Hi I got a new 1900mAH battery (By Feipusi) and I use it for a week now, though I noticed it doesn't do it full work and the battery status bar is sometimes incorrect, is it true I need to discharge->charge it 4-5 times? Do I need to charge it when the phone is off?

Hello!
Have you wiped battery stats? And after every rom flashing I charge fully, than discharge fully my phone once! So it's not needed to charge and discharge fully your phone 4 or 5 times....
When I discharge and charge again do I need to turn off my phone?

First charge up the phone, and wipe battery stats in CWM or with an app from the Play.
Than let the phone copletelly drain and it will turn off itself... Than charge up fully and turn it on. :good:
And you will have a nice, calibrated battery.
ok I downloaded a tool, it says STEP 2 OVERIDE, what does that mean?
I've installed almost every roms. Even installed golden kernel. Hotplug and cqf combination. Did full wipe. Howw come my battery did not last more than a day? I alwats notice in settings >battery. My screen is always high. Its eating up my battery. Stays at 55% to 60%. anyone have idea?

Whats your brightness at? If screen is eating up all your battery, most probably it is too high
I put it in the minimum. Im kinda paranoid that my phone has hardware issue but the phone is working fine. Im still finding solution why im having this prob. Still not losing hope. Lols.

if you've tried goldenkernel v2? then setting the hotplug and battery saver mode on, hopefully this can help you, especially if you use benzrom v6
Recalibrate your battery. Thats what helped me. my device can last 9 hours and still remain 70% battery with normal usage.
Heres how i callibrate.
1) download battery callibration in market.
2) charge the device till 100% (Dont plug it out)
3) power off the phone. I dont know if this will work on ur phone but i get 0% again. So charge it fully again.
4) once it shows 100% , unplug and plug it in again and wait till it reaches 100%. Do it for 4-5 times then reboot.
5) when your phone boots up, it wont be fully charged, so leave it charged till the battery full indicator shows up. Unplug and plug it in to charge again. Keep doing it for 10 times and the battery full indicator will pop up even quickier then the first time.
6) once u done it, open battery callibration and click callibrate.
7) after that, unplug your device and use it . The battery will last very long.
8) use the battery till 1-5%, u can completely drain it but i didnt do that cause some of my data will be removed after i completely drain my device.
9) charge it up to 100% again but dont use it while charging.
10) after that, enjoy ur battery life

Try using Better Battery Stats (you can get it free from xda) and use your phone normally for a day then see what is draining your battery
Anyone can help me pls?

I've got a doubt about battery discharging in my phone. When it normally discharges from 100 to 35% everything is in normal, with similar drops every hour for ex. 2 days. But (even in standby) when battery is on app 35% I see very fast drop to 25-20% in couple mins. At the beggining I thought it is maybe broken cell in battery but I notice that around camera surface is warm, not hot. So it is probably matter of software. What drains my battery so fast and always at app 35-30%? Do you have similar issues? I made factory wipe few charging cycles ago but it did not make any changes.
Do you use any of the power management settings like stamina more or....
What apps do you have installed?
Sent from my C6603 using xda premium
Yes, I always use stamina, I switched it off just before taking picture. I use dropbox, GO backup, Network Singal Info, netmonitor, Gmail and one additional mailbox. I have Google backup - off, Hangouty - logged off, google now - off.
Well, I don't use stamina mode anymore. I too had these sudden drops when stamina mode was on.
Try switching off stamina for a couple of cycles.
If you find that there are no drops, then you have your culprit.
So you mean not use stamina at all or switch it off at around app. 50%?
Try without stamina mode.

Deleting battery stats does nothing. I post this every time I see someone recommend it, but I feel that the point needs driving home until people realise that it is a placebo at best.

Sorry, it will not improve your battery, just if you have wrong indicated battery %,it maybe solve that. I solved a problem like that.my battery went from 50% down to 18 in a cuple of min.after deleting the stats and a few charges it was O.

No. The batterystats.bin file has no relation to the percentage displayed in the notification bar. It is used to calculate the usage statistics displayed in the battery usage section of settings. Nothing more. The file is deleted every time the battery is fully or nearly fully charged anyway.
The G+ post I linked to was written by an Android framework engineer, so I think they know their stuff

Ok,maybe i'm wrong,but somehow my problem was solved
I am sure that I hadn't wrong percentages but period of strange drain battery (when % suddenly drops) because I felt warm temperature around camera. So I suspect any strange thread/wakelock/trigger.
