Search will answer your question .
Basic answer is due to user apps or rom or kernel or user read better battery stats thread first .

Hey everyone, I have been having this issue with my SGP 5.0 International for a while now. For some reason when I charge my device until it says "Fully Charged" and then unplug it from the charger it instantly goes to 90%. I'm currently running JackpotClavin's 4/14 CM 10.1 Build but this has been happening on every rom since I changed from stock. I tried wiping battery stats via the application "Battery Calibration" in the play market by overriding the wait till 100% option but it still happens. Any ideas on how to fix this? It's a bit annoying.
Try booting into recovery and wiping your battery stats that way. If that does not work, try running the battery all the way down, then charging it all the way up a few times, I have heard that works.

Do you charge it with the device switched on or off? It should be switched off before you turn it on and check the stats.

My CWM does not have a wipe battery stats option otherwise I would have tried that one first. I am going to turn off the device and let it charge overnight while the device is off and see if that fixes it. I'm just a little confused as to what is causing this since I have had this happen across multiple roms all the way back from custom stock based roms.
yeap does the same on US edition too I am PacMan Rom... any one found a fix ?

Nothing for sure so far. Wiping battery stats did nothing as suggested by many others but it seemed worth a try. I am currently in the process of completely draining the battery on my SGP and then recharging it to see if it goes away. I will update once it is recharged.

That's strange, I don't have any issues with USB. The only issues I've had are low bars for WiFi and the battery not showing 100%.
Well at the end of the day ignore what the stats say. What matters is if the battery does its job or not.
You should do this once every 1-2 months (or after about 50 cycles of charging):
1) Discharge completely the battery until the device turns off itself.
2) Charge the device (better powered off, but on CM10.1 for SGP 5.0 there is a bug and the device turns on when you plug the charger, I don't know if it is solved) and wait further 2-3 hours when the message "Charged" is displayed. Approximately wait 6-8 hours for complete charging.
3) Unplug the charger and turn OFF the device, wait 10-15 minutes with the device off.
4) Connect again the charger and power ON the device, wait 5-10 minutes after the message "Charged" is displayed.
5) Repeat steps 3) and 4) at least 3 times.
6) Now android can read correctly the battery voltage for a while.

If you don't care about keeping the battery at 90% after plug out, then there is no reason to post in this thread.
I used to do this since i bought my first android device, and everytime worked.
If you have an idea please tell us.
I should say that the power issues were usb related. probably to some sort of issue with the power circuit; in my case, on the usb end. Either massive discharges or false reporting (eg 100->30%)
If u don't have any usb issues in the near future, its probably just the usual sgp faulty power reporting issue

Any scietific explaination for such a 'method'? Because it sounds very funny
Do you know how the battery percentage is calculated in our devices?

If you want scientifics explainations, google is your friend and no, I don't know how the batt. % is calculated on android. I only know what i've read about and that this works nicely for me since I had the same problem, so I shared my experience.

I will have to try this and see if it helps. I just finished a full charge/discharge cycle with no change. It still only charges to max 90%. Thanks for the suggestion.

No need to be so rude and post a comment with no value. I'm fairly sure post spamming is against forum rules.

I'm fairly sure it doesn't have anything to do with the cable/power adapter as I currently use and have been using for some time 3 different cords/plug combos as well as changing the socket I use to charge. I have heard of the faulty power reporting but even if that is the case the main reason I posted to begin with was to try and sort all that out.

Thanks for mentioning this. I don't have any battery stats issues, but I would be interested in seeing how turning my device off and then fully charging it affects my battery. Now, will I be able to withstand an hour or so without my Samsung Galaxy S2? We'll see.

I've read a lot about this issue on many forums and never got an answer that gives me peace of mind.
I think all that matters is that the device is charged while switched off and that's it.
If you charge a device while it's on it can generate a parasitic load and that will screw the battery stats and age the battery prematurely.
I had some problems like that when I used my brother's iPod charger. Try to switch to an original Samgung charger, if not already using one.
I bought this phone yesterday. I used opera and whatsapp in wifi and my battery went from 90% to 66% in 1 hour. Also standby battery drain is a lot about 10% in 2 hours. Is this normal for this phone? The battery is good i know but for me the battery is bad.
I have to send it back right? I am on 4.1.2, lastest update
Edit: BetterBatteryStats told me that:
18,2%/h. Crazy

That is normal if your have 3G/wifi on and some application prevent your phone to go to deep sleep mode. Please install CPU spy and wake lock detector to see what is the problem.
When I'm on JB 4.1.2 stock rom my battery is last for about one day with 3G/Wifi on (depend on which is available).
I got finally down to about 20% standby drain/day. Which is still too much IMO.
Biggest improvements came from the disable-wifi-in-standby Feature and from disabling Googles tracking service(not the location services).
Guys how good is your battery ? I am scared to get this device . How much SOT do you get ?
3 - 4 h

On my LG G6 i get around 6 to 7 SOT so is 3to 4 good or no ?
As for me it is a completely satisfying sot time. The phone works from morning till night and that's enough for me. At night I connect it to charge. If I have an intensive day, I will install incipio power pack.

SOT depends so much on the individual. If you want to be certain then buy a battery mod. The mods are one of the advantages of the Moto Z.
is good，5 ~ 6h display, but i not play game.
5 to 6, no games. Mostly just a bit of browsing, Xda labs, texts. Not much else.
Over 8 with the incipio battery mod.
As said earlier though, hard to compare, since we all use our phones differently, and our setups are different too. But my Z is pretty near the same as my N6 was. Without the battery mod. :good:
Hello everyone !
I've got a little problem.
My battery die fastly. The phone is all new and the SOT is near 2h max. And I do nothing more than SMS, browser and apps like.
No games... I'm afraid of testing that.
Hi all. It's possible to disable fast charging? I search this options in menu and developer settings but i don't find it.
I want this options for my battery for long time live.
Sorry for my bad English.

There isn't any as far as I know. Just get a charger without fast charging.

Use a normal charger . But why you think fast charging will reduce battery life?
@up Yes normal harger reduce temperature battery, battery no like high temp... But I test using normal charger and fast and i have bigger sot using fast charger . Now i use only fat charger ...

I use my phone a lot for gamers purposes, I understand that it is not ideal but it is necessary to charge while gaming. The problem is, at some point the battery tends to decrease its percentage even while charging until sometime in the middle of a match the phone runs out of battery power and shuts down.
Upon starting again, I continue to gaming and apparently the charger can supply.
Reading the forums I saw that ROM programming prevents fast charging at high temperatures, does anyone have a solution for this? Would using some kernel, thermal (chrysalis, etc.) help me in this case?
It's annoying while I gaming having to worry about low battery.
I appreciate the attention of anyone who can help me!
Solution is simple. Stop charging battery while gaming. U killing battery fast.

I understand that, but it is playing 40 minutes to load 1 hour ... so I made the topic, for a solution, anyway thanks.
My biggest problem is having to charge the device but even when plugging in the charger keep falling.

That is a safety feature to save not only the battery but also you. It is dangerous to disable this, seeing the way you game.
Is the phone overheating? If yes, you need to cool it or get used with it
If not, try changing your cable and or charger. Cables can be tricky, chargers can be tricky too and the combo with bad cable and bad charger is a showstopper. Using the original charger or a standard USB charger capable of 3amps output is a must. Using the original or a good replacement cable is also a must.
Then try the Ampere app - measures the current flowing to the battery while charging. 2.8amps is excellent. It only occurs at cool ambient temperature and if you're not using the phone actively while charging.
1.5-1.8 is good if you are using the phone while charging. 1 amp is not very nice but will keep your battery from loosing %. If current drops below 0.5amps you will hardly gain any % if you use the phone in the same time and more likely it will be dropping.
Note that you must do the check when your batt is, let's say, half charged. The closer you get to 100% the lower the current goes for safety reasons.
Sounds like the 'regular' battery drain in stock miui combined with a crappy cable / charger really..
Quality chargers ( blitzwolf and anker for example ) are very worth it and offer peace of mind at the same time imho..
