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?

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
my note is draning 1 percent every 10 minutes
when in standby
after downloading cpu spy i discovered that deep sleep was 1% and 200MHZ was 84%
it has something to do with it?
also in battery usage
android os is 57%
any fix?
by the way
im running ics stunner rom
The Note's battery is a POS... If you want to partially solve it you'll have to keep both wifi and data off.
i kind of found a way now deep sleep is on
but what do you mean POS
Have you changed anything in the last days? Installed any suspicious apps, or changed any settings?
If you found the problem now, then maybe you can also calibrate your battery just in case it "lost" some performance. To be sure!
Use Battery calibration or wipe Battery stats in Recovery, Anvanced menu (after you fully charged your device).
I installed the CM11-M9 in my NOOK HD+ last week. So far I have a good experience especially changing the runtime to ART. The only con is the battery becomes unstable compared to stock ROM. The problem I have encountered is battery drains extremely fast, from 100% to 60% within 1 hour and then drops to 1% about 30 mins. The weird thing is the battery still holds near 3.5 hours at 1% battery level. I tried to reinstall CM11 for but have the same issue. Anyone knows how to fix this problem? Thanks a lot!
Perhaps an app your using has a battery draining bug on kitkat that wasn't present on earlier versions.
You don't say if it occurs after a clean install of cm11 with no additional apps downloaded/installed.
So I have android version 5.1 with the latest CyanogenMod nightly and my battery seems to drain extremely fast. About 5% a minute without the charger and 1-2% every 8-10 minutes with the charger. It over heats extremely fast even when I'm not using it for anything major I've checked my apps to see how much battery % they use I just don't get it I've had the phone for about 5 months and never had this isue . it started yesterday evening I had the viper one ROM installed so I thought that it was causing my issue so I flashed CyanogenMod and still have the same problem. I've tried letting it drain completely then charging it for 10 minutes then holding the volume up down and the power button for 2 minutes and even that didn't help. I just hope it isn't fried. Is there anything I can do or am I just completely 100% out of luck ?

Did you actually check what exact process is draining the battery from the Battery usage option from settings?
i would strongly advise against using the phone in this condition as you will permanently damage the battery(if you haven't already). I noticed a recent increase in battery drain but not as significant. The drain you are talking about is abnormally huge, do you remember flashing anything or installing any app? Generally there is a known issue with Google play services causing huge drain on several lollipop devices.
Try installing Amplifier (xposed module) and disable as much as you can of wakelocks and alarms in the "safe to limit" list.
Try wiping the cache/dalvik cache from the recovery. and/or "fastboot erase cache"
Install GSam Battery Monitor and share some screens
I just replaced the battery in my M8 and while the battery is fine with the screen off, while using the phone for normal activities, the battery drains about 1-2% every minute. Is that normal? My last battery was terrible and would die way quicker.
I run CPU tuner on a normal profile mostly and currently running GSAM to see what's draining it.
It seems to be the system and kernel using most of the battery
I've tried several roms/kernels and i have the same problem. The battery drops about a percent every minute or two while the screen is on. My phone maybe lasts 6 hours at best. Currently running the latest version of SkyDragon. Is there any type of diagnostic I could run on the battery to get more info. Does anyone have any advice?
