Seems I fixed mine. I had put an extended battery on this guy, and it would never change in battery level. I would have to reboot the phone to get it to register the new power level.
Discharge your phone to 0% until it shuts off. Try to turn the phone on several times to make sure its discharged (should shut off immediately). Charge the phone to 100% without unplugging it (will take a while, do it over night).
Today my % seems to be registering and no need to reboot the phone to change it. HTC tech support claimed they had nothing to do with the battery manufacturing so they wont help you.
if you reboot your phone how accurate is it to the actual battery meter showing you the percentage? I am at 6 percent left on my phone in hopes of discharging it and than charging it full to get mine to work

It will still probably jump down about 10% but it will sit there for a LONG time until the system is actually to that percent. My recommendation is dont reboot the phone if you want to keep accurate %. The rebooted value I dont believe indicates actual battery life remaining. There is a communication problem between the phone and the battery - HTC confirmed this is going to be patched (on the phone with them last night).
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.

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.
I bought my Xperia L about 7 months ago. It drains out battery level from 100% to 0% in about 3-4 hours and turns off. Without charging If the device turns on, the battery level shows around 90%, And so the same procedure keeps repeating. I do not charge the battery. The battery has charge in it but the system is showing the false batter level.
I even updated the software and also run the system repair but nothing improved.
Can someone help me please!
Thanks

Sounds like defective battery. The thread will be moved to appropriate forum so that the right experts may chime in.
Hi there!
My honor 6 is fallen in water a couple of months ago. Hardware and software is ok but after charging the battery (to 100%) the phone thinks it's still under charge showing the message "under charge" and the led light stays swiched on for a lot of hours. But when the battery indicator decreases the value ( about 58%) it suddenly switch off the phone.
Do you think is the battery damaged of can i "calibrate" it again?
The battery quality seems to be ok, i use the phone all the day without problems ex pet this indicator fail.
Thanks for our help!!!

It seems like a hardware problem. Try a factory reset and see if it persists.
You can also give light manager a try if you are rooted...
bad battery probably from short circuit
if it under warranty dont try to do any . just go service make them try to know where exactly the issue !.
I just had a new battery installed in my Pixel by Ubreakifix because my battery had been draining quickly. My problem is that the battery continues to drain quickly even with the new battery. My understanding is that they install OEM batteries so I don't think that the new battery is the problem.
So, I tried to calibrate the new battery using these steps found here:
1. Discharge your phone fully until it turns itself off.
2. Turn it on again and let it turn itself off.
3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4. Unplug your charger.
5. Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on-screen as well.
6. Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
7. Repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without it being plugged in.
8. Now, let your battery discharge all the way down to 0 percent and let your phone turn off again.
9. Fully charge the battery one more time without interruption and you should have reset the Android system's battery percentage.
I seemed to get caught in an endless loop on step 6. After charging the phone to 100% on step 5, I would disconnect the charger and restart the phone. Every time the battery percentage would drop to 60 or 70 percent after restart. After doing that about 5 or 6 times, I gave up on that step because it didn't seem to be making any difference. One cycle of doing this tends to take several hours because of the charge time from 60 percent to 100%. So, this ended up being a many hour process. Should I have just kept repeating step 6 over multiple days in the hopes that eventually after many charge/restart cycles it would eventually register 100%?
Now the battery calibration seems completely out of whack. I have fast battery drain and the pixel shuts off sometimes around 30 or 20 percent remaining battery. Now with minimal screen on time, the battery might last 8 hours. It used to easily last all day even with moderate screen on time.
Any help would be much appreciated!
I would take it back to Ubreakifix. Tell them the battery drops from 100 to 60-70 after a restart. It sounds exactly like what you would expect from a bad battery.

Yep did that already. They replaced the battery again (for free) and still the same problem. The technician said that this has been a common problem for many pixels after they’ve replaced the battery. He claims it’s because the pixel can’t handle android 10 but I don’t believe that.
I recently bought used Pixel and Pixel XL.
The XL exhibited the exact problems you mentioned (looping steps 5 and 6 and shut off at around 20% mark). Even have this on camera (btw, split screen opening some games like PUBG with your battery status on the other side is a good way to drain the battery and show battery percentage). Not sure if the battery was previously changed but I took it back to the seller and got a refund.
On the other hand, the Pixel (non-XL) is running on Android 10 just fine. Did the battery calibration as you mentioned and it was good to go.
