Hi,
I am experiencing a strange battery indicator problem.
New GT P-5110 with stock rom, not rooted.
Whith fully charged battery, when tab is left in sleep mode or shutdown, buttery indicator goes down in zero time, or UP without being connected to charger.
Also tab will sometimes shutdown when in sleep mode. I suspect is has something to do with suddenly dropping charge value.
Any ideas if this may be software related and fixed whithout sending the tab to service center?
Appologies for my bad English.
Thanks,
Dimitry
Hi,
In case anyone encounters the same problem, the solution is to perform battery calibration.
1) while the device is switched off charge to 100% and leave the device OFF for at least 1 hour.
2) discharge the battery to 40%, switch the device OFF again and leave for at least 1 hour.
3) discharge the battery completely and leave the device for 1 hour.
4) repeate the steps above 2 - 3 times, then the problem disappears.

I always have battery issues on my HTC HD7 with deepshining rom and i want to know if there is a fix for this without having to replace anything.
First scenario is that whenever i charge my phone from "Battery critically low" state it takes less than 2 hours to charge it to 100% but when i go out and use it for a while it goes from 100% all the way to 20% in an hour.
Second scenario is that I woke up today with full battery life on my phone but then i restarted my phone and it went to 65%.
Is this a battery problem,Rom problem or charger problem? Is there a fix?
I mistakenly posted this in the wrong forum at first, so here it goes again:
I bought this Galaxy Tab 2 10.1 (GT-5110) about a year ago, it runs the original firmware with the recent Samsung update to 4.2.2.
Lately the battery life has become very short. This was not a gradual change, but something that seemingly happened over night. I charge the device with a travel adapter that claims to output up to 1 A. The battery monitor shows that charging works as expected and the device charges to 100 % .
In use the battery shows 100 % for a while, but after about 20 to 30 mins jumps to 4 % , giving me the low batter warning. I am travelling and the only change I can think of is, that mains power here in Canada is 110 V instead of the 220 V back home in Europe, not that I expect that to be a problem.
I don't notice the device getting warmer than usual, so I don't believe, that the battery really charges to 100 %. Is there anything on the software side I can do to investigate this further?
Thanks for any advice!
EDIT: I just noticed, it's actually not the battery, that is dying. It is a error in the measurement. The battery life is normal, however the charge measurement shows nonsensical behavior: It goes to below 10 % in less than half an hour and then goes back to full, repeating this in cycles, like a sawtooth wave. So I suspect either a hardware fault in the measurement circuit or a software problem.
Here's a screenshot of what the battery info looks like, mind you the device has not been on the charger the entire time:

i think the problem is with the charger
drain the battery of your tab completely and then charge it fully upto 100 % with stock original charger and see if you notice any difference

What makes you say that? I've been using that charger instead of the Samsung charger at home for a long while now.
For me it may be the hardware issue, because software doesn't consume battery in the background so rapidly.
#If you are not sure try this options
For Hardware issues:
*Make sure your charger is working properly (Completely drain your battery and then connect your charger and charge for few half n hour and then reboot your phone and check your battery status and use your tab normally for few minutes and keep an eye on the battery consumptions)
If your battery is gradually decreasing no fault to your charger.
If your charger doesn't charge then its the time to either change or repair your charger.
For Software issues:
"GO TO BATTERY SECTION IN SETTINGS AND CHECK WHICH APPLICATION REDUCES YOUR BATTERY OVERNIGHT RUNNING ITS SERVICES IN THE BACKGROUNG AND JUST DELETE IT"
*After using your tab normally go to SETTINGS>APLLICATION MANAGER> and then RUNNING SERVICES.
If you find unnecessary services running in background NY an app which is not required just uninstall those app.
*Try to check your Sync, WiFi, GPS etc. settings to ensure that any app is consuming continuous services and draining your battery.
*Remove recently installed app which are not necessary.
Hope they help.
Thanks so far, I just updated my original post to describe the problem more precisely.
a solution

I had this exact problem, down to the sawtooth battery status profile, tablet model and android version, and fixed it with the following procedure:
After a normal boot, press and hold the power button continuously.
The tablet will shutdown and reboot repeatedly.
Hold the button down for at least 4 complete shutdown/restart cycles, never releasing the button.
After that treatment the battery status shows a nice, normal discharge curve, starting from whatever random place the sawtooth pattern left you at. Run the tablet until it powers down by itself, and then recharge it.
The ugly sawtooth battery status first appeared on the tablet after running an intensely power-hungry application (the battery got hot after 20 or so minutes of running). After that, the discharge rate seemed to have a flipped sign, where if normal discharge rate per minute was positive, the altered, aberrant discharge rate was negative. CoPilot was the offending software; however, that may be a post hoc ergo propter hoc logic error on my part.
The messed-up discharge rate would prematurely terminate charging if the table was on, so the only way to get a full charge was to turn the tablet off and attach the charger.
This is my first time encountering this problem.
I was charging my Note yesterday when it reached 15% of the battery. However, even though it was connected to the charger and the charging icon appears, the battery life of my Note is decreasing until it drains the battery. I charged it overnight but unfortunately, It only charged up to 3%. I already sacrificed my files just to reset/reboot the Note but the battery won't still charge properly.
I've tried almost everything. Wiped the cache partition, rebooting the tablet, and uninstalling everything. But the battery stays at 0%. Is it the motherboard? Hope not.
I highly doubt that it's the connector/charger because the lightning icon appears when I connect it. I'm a newbie. I really want to identify the problem and solve it.
Define problem first to eliminate .
Replace battery or use another charger to rule out battery/charger problems .
Clean usb charging port .
100% charged battery that drops quickly >. factory reset first test again .
My Moto Maxx is never going below 15% battery for quite some time.
I was running CM 12.1 before and I am running the CM 13.0 preview now.
The problem now seems much worse.
This could be my battery dying?
Wait its not going below 15% or above 15%? Also, did you flash the ROM with a clean wipe (no dirty flash)?
Another thing to note is that the CM 13.0 Build is a "PREVIEW" which means that there are a TON of bugs in there. I would advise you go back to CM 12.1 for the time being.
It is never going below 15%.
On CM12.1 it also happened.
When it reaches 15% percent, the phone shuts down and needs to be charged.
After sometime charging, it displays the battery as above 15% and I can turn it on again.
Mine had always done that at 5 percent. Here lately it's closer to 7 percent.
I'm on original 5.0.2 and also facing that issue... I've heard onde it's related to the use of non original chargers, or even QI chargers... Never got rid of it, even after a full wipe/factory reset...
I've had this problem too and made a post over in the Droid Turbo forums but no one ever replied..
At least I'm not the only one that has this problem.
Yeah I've always had this issue between 5-8% on my three Turbos. Stock Rom and other flavors. They all shut the phone down around there.
Solved the problem with this app: https://play.google.com/store/apps/details?id=com.newagetools.batdoc&hl=pt_BR
Now my battery goes down to 1% again, yahoo!!!!
how can that app fix it?? i would think its a placebo effect as i see dificult for an app to read or fix battery info...
maybe it locks out the bad parts (like an old chkdsk on a HD)
anyway i will tryit if i see it tries to go rogue with the Ads it Dies..
Batteries in laptops and phones have a file that keeps track of battery life. They use this to estimate percentage.
Sent from my DROID Turbo using XDA-Developers mobile app
still having this issue
I have the same problem. It started as shutting down at %5, then %7, now it's %15 shuts down.
The same thing on my XT1254. It shuts down near 5%, I will try to charge it with my old i9505 charger, it could be a problem related to TurboCharger.
Hello guys,
My girlfriend's phone had this issue some months ago, what I did in order to fix this issue was:
1) Let the battery drain until phone shutdown. (try to turn on again until you cannot)
2) Fully charge with an original Motorola charger (phone turned off)
3) When it reached 100%, turn on the phone but enter in the fastboot mode and wipe caches
4) Uses the phone normally and let reaches 0%.
Making these steps, the battery back to have a "normal" behaviour

I´ll perform these steps, thank you
Although you see the battery as percentage, the operating system does not see it that way. It uses lower limit voltage of the battery to shut down the device in order to extend battery life. Batteries do not like to get and stay deep discharged (below low level voltage)...if you do this frequently, you will severely hamper your battery's life.
I just had my Xperia Z5's battery replaced due to it bloating up. After two weeks, I noticed that the battery indicator isn't working properly.
It would go down from 100% really fast (even during standby - not using the phone) but stay around 30% down for a really long time. No difference in usage. Then it also started restarting on its own even during standby. I would check my phone and it would need me to input my pin saying its required after a restart. Another instance, I was still typing out a text message and it restarted on its own. The battery was around 60% before it restarted but after it turns on again the battery indicator showed that its at 40 something %. I don't think the battery would drain that much just from restarting.
Also, just today, it won't charge properly anymore. It will detect the charger, like it would make the sound when you plug it in but the battery icon won't change to the charging icon and the battery will continue to drain. When turned off, it would show the Sony logo then battery level on the screen but will stay at 0% or whatever % it was left at and will continue draining.
So my phone just died earlier and I just went to plug it in hoping it would still work. The battery was stuck at 0% for the longest time so I just went and left it for a few hours. Coming back to it, I noticed that the LED indicator is green. I pressed the power button and it showed 100%, then I tried turning on the phone. It still turned on, showing 100% on the battery icon and could be used like usual.
I can still use the phone, barely, but this issue is really annoying. I'm not even sure if the next time it drains it would charge again.
So far, I've tried:
using a different cable and charger
doing a factory reset
doing a repair via Xperia Companion
But the issue still persists...
Is there anything else I can do on my end to fix this?
You should replace your battery
Hello.
I'm sorry to hear that your Xperia Z5 got this problem.
Here're some personal experiences:
1.Just replace a battery for it.My Xperia Z5 had same issue last month:Its battery lasts for only 2 or 3 hours,and charges much faster than before.Then I think maybe the battery life loss too much,so I bought a battery from taobao(A Chinese Website),then everything's fine just as when I buy it.
2.According to your description,maybe the sub board(It's responsible for charging and data transmission)is broken too.You can find a used one at ebay.
That's all.I hope this message can help you.And...I'm a Chinese so maybe you can't understand my Chinglish(It means "Chinese English" )...Sorry for that.
