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).

This happened twice today..
For e.g: If my battery is showing 15% and then i restart my phone it suddenly shows 50% remaining..
Am using Battery Indicator to show me in % how much is remaining (though even the htc battery shows the difference in this case)
Any idea why is this happening and how to solve this??
Oh and how to stop the: Show Me app?? Keeps restarting and sucking my battery..
Could someone please help me out here with this weird problem??
It keeps happening everytime i restart my Sensation..
Try wiping your battery stats from CWM.Then charge battery fully>drain fully>then charge again it should be calibrated. oh and use startup cleaner in the market.

Its a 1 day old Sensation.. Havent rooted it yet..
I saw the same with my mine. I allowed the battery to drain until the phone shut off and recharged over night to 100%. I did that for a few cycles and mine seems fine now.
The battery % indicators only show what the phone software *thinks* it currently is.
The Sensation battery ranges from approx 4200mV (full) to 3000mV (empty).
The problem is sometimes the phone thinks those numbers are different. E.g. when you turn on your phone for the very first time, or flash a new ROM, if your battery was half full at 3700mV the phone would then think that was the 100% level (why they say charge a battery fully for a long time before turning your phone on for the first time).
This leads to various funnies such as a battery seemingly staying full for ages (the phone thinks 100% is much less than 4200mV so until you drop to the phones level your battery %age doesn't go down), and seemingly rapid drains where you end up with less than 10% left - but probably find in reality if you left it your battery would go on for ages at 0%.
Over time it learns, but best to wipe your stats after a long charge so it knows that 4200mV is 100%, and then don't charge your phone again until it physically runs out of juice so it knows what is 0%.
Another useful tip is to install the free BatteryLife widget from CurveFish from the market. That shows you the current voltage level as well as %age, so armed with the knowledge that full = approx 4200mV and empty = approx 3000mV you get an exact idea of how much you have left.
Mine does the same thing even draining/charging for few cycles

Yeah... I went to sleep with 100% charged and when i woke up it was yet 100% charged.. And when i check the battery stats it shows 0s but i was asleep for 8 hours.. Any way to solve this on an unrooted phone?
I had the same problem today too! Thought my battery was kicking ass...turns out it was 18% when I restarted my phone

What did you do about it?
Anyone know what to do about this to an unrooted phone??
Or is this a defective piece and i should get a replacement??
Mines has done the same but I haven't had the chance to calibrate it yet to know if that'll help. It has helped on previous phones. I don't think your device is defective though.

How do you calibrate an unrooted device??
I think it calibrates itself after a few charge/discharge cycles. Always charge it a lot longer than when the green light comes on (because if the phone thinks the 100% level is a lot lower than it should be, that green light may come on early), and for the first couple of charges let it dry out rather than topping up.
And install that BatteryLife widget from CurveFish, then you can look at the voltage. 4200mV = full, 3000mv = empty, regardless of what your battery %age says. Mine currently says 51% and 3753mV.
Having the same problem here, restarted my phone afew times now and the battery % keeps going up, then dropping rapidly! :s

I'm running the 12/28 CM10 nightly, and I'm having an issue with charging my battery. When the phone is on, the battery charges normally to 90%, at which point the LED changes from red to green, indicating full charge. If I leave it plugged in, the phone continues to charge to 100. However, the battery doesn't really charge past 90 because once I begin to use it the charge drops really quickly down to 90. Similarly, if I restart the phone, even if it said 100 before, when it is on again it says 90. I have had this issue with previous CM10 nightlies as well. It is a software issue, because if I turn the phone off and charge it, it charges to 100.
Any ideas on how to fix this? Thanks!
This is a suggestion out of the blue but maybe try recalrubratung your battery

This is the intended bahavior. The type of battery used in phones last longest when they say between 80% and 20% of charged. So your phone will pull the maximum amount of power it can until it hits 90% then reduce power draw to a trickle charge.
The rapid drop is power is often the chip in the battery lying that it is fully charged when it is not. That is why you may see a rapid decline to 90% where your battery drain will go back to normal.
You might also see the phone telling you that it has 15% power then turning off. Upon reboot it will say it's at 0% or 1% that also is the battery trying to protect it self from damage.
This is a simplified explanation of how all phones work these days. The only difference you'll notice is how good the software is designed to lie to you about the power level. If it's good you won't notice these types of anomalies but they are still there.
Have you wiped battery stats?

Thanks for that informative answer. So I take it that means there would be no performance difference between turning my phone off, charging it, and then using it (with it saying 100%) vs leaving it on, charging it to 90% (green LED turns on) and then using it?
Hi all,
Well, seems my battery had completely lost it recently . When I was charging the phone, it made 30% jumps (from 20% to 50% in 5 mins of charging) and then I was getting low battery notification very quickly.
I decided it was time for a complete battery drain and slow charging through usb (hadn't done that in a long time) and indeed, it seemed to start charging normally. It took around 3 hours to get to 86% but then it stopped charging saying "Charged" while at the same time the battery indication was at 86%!
Unplugging and plugging it again (in usb or AC adpater) didn't seem to do much as I was instantly getting the absurd message "Fully charged - 85%" !!
So I think I've corrected the problematic behaviour for the most part (as it charged correctly until 86%) but seems I am still missing a small part towards the end. How can I fully correct this and get it to charge until 100% or the max percentage the Nexus S gets to normally (95?) I am using rasbeanjelly and TWRP recovery if that's of any help.

I don't know what recovery you use, but in CWM there is an option to wipe battery data, you could give it a try..

Just to give an update, seems all it took was repeating the above procedure a second time. Now I get to 95% which I think is the standard for this phone,
Cheers.
Not sure what's happening with my phone, but after removing the plug on my fully charged phone, I will let my phone sit idle for about 10 mins, when I go wake the screen, I see that I've already lost 3% of battery capacity.
The weird part is after this initial 3% is gone, my battery will drain normally. Does this mean I need to calibrate my battery? Is there anyway to do this without damaging it?
It means you need to get a new hobby... seriously, why do you care if it changes nothing what so ever. In order to fix this, you should try not checking your battery percentage every 2 minutes. On the upside, this will probably give you another half hour of battery life as well.(damn a change of attitude would fix like 90% of problems on this site)
On a more serious note, it's likely just because your phone doesn't keep charging when it hits full charge, it stops charging in order to not kill your battery, and lets it drain to like 90% at which point it will charge back up to 100%, so it may be at any point in between when you disconnect it. Even if it is truly at 100% when you disconnect the charger, the measurements may not be completely accurate when approaching 100%, so it is likely, that could make it drop faster at first. You need to do nothing in order to fix this, seriously don't mess with it.

Are you running stock or custom kernel and any custom ROM? Ive noticed this sometimes too but that's because the phone, when unplugged is running services to start phone on battery power versus the cord/wall charger. Check logcats to see what happens when phone unplugged to see what may be happening when phone starts on battery.
I think you are worrying about it a little too much. It could be searching for service (which drains a lot of battery), starting services as someone previously said, heat is horrible for a battery, anything. If the drain is normal after that who knows it could be the ROM you are on, battery percentage not being reported correctly.
Not worth an RMA by any means. Reset battery stats in recovery and see how that works out for you.
Bear in mind, these batteries are cell batteries, a user who plugs their phone in every time the battery hits 50%, is going to notice over a period of time the time it takes to go from 100% to 50% is shorter and shorter, and suddenly, 49%-0 holds a better charge. If you're constantly charging your phone, you'll wear those cells of your battery down. This is where the "hoax" of always letting your battery drain to 0% when you get it to "maximize" battery potential came from.
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.
