Your phone starts to shut off at 20-30%?
yep
sounds like a defective battery.
I've gone from 100-0 a few times and it's never shut down before 0.
Try this after wiping cache only in recovery mode:
After phone turns off, try to turn it on and see if red writing appears, telling you that your phone doesn't have enough battery. After that, charge your phone up to 100% and leave it at that level still connected to the charger, for 10 minutes. Then use up the battery normally. Repeat until phone shuts off at 0%.
This might be a little late for your question, but I just want to share my experience here.
Recently, my phone kept turning itself off at a little below 30%. If I tried to turn it on immediately, it showed the red low battery alert. If I charged it for a few minutes and turned it on, the battery would show 30%+. That proved it had not suddenly dropped to zero and turned itself off, as I understood a defective battery would.
I checked the Net, and it seemed that lots of people have the same problem as mine. On top of the recommendations were to replace the battery and a factory reset.
With the info I gathered, I decided to try battery calibration, and installed this app (https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en).
I restarted the phone three times before running the app (idea from an OP discussion). As instructed by the developer, I let the phone continue charging even when capacity reached 100% (orange container on top). In my first try, I only waited for the orange container below to fill to the max, then started calibration (even when the pop-up message was telling me it's still early). That was a mistake. After that, the phone started dying at a little below 40%. In my next try, I let the charging continue even when the orange container at the bottom showed full, until the app notified me it was ready for calibration. I calibrated, and my phone's battery is fine again.

I realized the mistake in my title...reporting NO charge.
I previously posted about how after clearing my battery stats it was reporting a 0% charge. I was able to leave it on the CWM screen for upwards of 5-6 hours, but the instant it loads up the OS the phone buzzes and turns off.
Now:
I got a new battery today and it appears that the battery is NOT the issue. The phone still reports a 0% charge, regardless of how long I leave it on the charger.
I'm unsure of how this could have happened, and I was curious if there was a way to completely reset the phone. IE: Every file exactly where it was when I first booted it up.
Any help would be great. I have an XPERIA Play as a back up, but I'd rather have my Thrill back.
Thanks in advance.
My phone has water damage. I currently have it in a bag of rice to hopefully bring it back to life. After a few hours I plugged it in to see if that would help, and I it had a strange activity. The LED in the phone handset was lit and green. I never rooted it to enable the LED. Any advice would be great!
PS: Sorry if this post is not the most coherent. I am currently very hungover, and having problems functioning. Also, I have no idea how my phone got wet! Happy Sunday to me!
Try a battery reset
The Dirtydee Z3
The led turns on when the battery is so low that the display can't turn on to show that its charging.
Device should turn on after sometime

As @adity said above, the LED turns on when your battery is too low to turn on the screen.
Charge it for some time.

Testing that now. Thanks for the heads up!
Fingers (and toes) crossed!!
You should've let it rest on rice for like one day.
On the good side, the moto x is kind of water proof.

*Update*
The screen is now on and showing 0% battery. It has been plugged in for hours now with no change in level. I was able to get into FastBoot, however any option I choose results in the phone rebooting back to the battery charge level screen.
Thanks for the help!
*Update 2*
I plugged my phone into my cars 2.1 amp charger and after 20min or so it showed 100% battery. The phone booted, however it did not complete and turned off. When it did It read 0% once more. I have tried volume down and power for 3 mins with no result. Any more tips?
* update 3*
I pulled the back over off and held the battery ribbon down. LIFE!! Phone displayed 100% and it was running fine. However, when I removed it from power it shut off immediately.

your battery is bad

I thought so too. I let it charge over night while it was cycling the boot screen, and when I awoke it was perfect. Battery 100% and turned on without issue. I understand letting your battery hit 0% is bad, but having it completely malfunction for 24+ hrs is rather poor play on Motorola's behalf.
How do you know that it's moto's fault?
Perhaps there was still some water left in your device?
This took longer to dry and caused the malfunction...
Don't judge so quickly!
I tell you this, because I had a motorola x with the same problem, the solution was to change the battery. Solved, try another battery
Dropping phone in water and having issues after is Moto's fault....? :silly:
I'll add... Water can and usually does wreak havoc on these things. Anything can go wrong after. Usually I'd say move on. Don't waste time or money trying to fix it.
You maybe were lucky. :good: But to suggest it's Moto's fault is crazy. Lol My X has died many times and 30 seconds on the charger and it boots. Anything you experienced was from the water.... Not a defect.

You put your phone in water, then turned it on again after only trying to dry it for a VERY short time. Bit amazing it even worked, and your complaining because it worked but only after drying?
Jesus man.
Pretty sure LIthium Ion batteries don't like going down near zero. Even when your phone says zero% and the phone automatically turns off it still isn't completely discharged.
I've let my nexus 7, and game controllers sit unused for a while. When you try to use them again they need a really long charge before they will work again.
The water probably put a load across the battery and nearly completely discharged it.
I actually just went thru this. I did the old school battery calibration using NeMa's app in the play store. Says to discharge 100%.. Phew lol. I was stressed. I had the same problems as above
Ok, so I have had no issues at all since buying this phone at launch, and this randomly happened yesterday.
I was on my phone and checked the battery info as I do a few times a day, just to see what's using my battery the most, SoT, etc. I was at 87%, which was about right as it has been off the charger a few hours with some light use. A few hours later I noticed my actual battery icon was exactly the same, no drainage at all. I viewed my battery info, and the line was flat for a few hours and still said 87%, which is very inaccurate as I've been using it during those few hours. If I had to guess, I was realistically around 60-70%. Then, while looking at my battery info, it said 'battery critically low' and shut off. I plugged in the charger and the animation when the phone is off said 0%. I left it plugged in for like an hour, and turned it on and it still said 0%. I unplugged the charger and it immediately died. I was on pop rocks ROM when this happened. I then plugged it back in, because the phone would function as normal as long as the charger was plugged in. I booted into recovery and restored an old stock backup, even after that I'm having the same issue. I downloaded a stock ROM from here, wiped everything like normal, same issue. Here's the frustrating part -- I chalked it up to this battery being bad. But I have two batteries, and the other one I hardly ever use, but I've used it before and it was fine and normal. I put that battery in, I'm having the same stupid issue! I don't understand, no matter what ROM or batter I use, this is happening. This is so frustrating, I don't know what to do or why this is happening. The phone will not charge at all. Please, anyone I would greatly appreciate help. I searched for issues like this on Google and here but it's usually chalked up to a bad battery, but I know that's not the case here. I couldn't find the option in TWRP, so I downloaded 'battery calibrator' app and wiped my battery stats, still didn't help. Below is a link to picture of what it looks like when I charge it, it just stays like this. I've done it with fast charging on, off, and with the phone completely off, same result.

Edit- One thing that was weird that also happened, was after I restored stock and then rebooted, I unplugged the charger and during the whole 'android is upgrading' thing where it shows the number of apps and such, the charger was unplugged and the phone stayed on for that entire duration. Then once it finished the upgrading thing, it immediately died. That is incredibly strange. Also someone mentioned maybe it's the charger plug in area not working properly, but that doesn't explain a battery going from ~70% to 0 instantly, and the phone not recognizing a charged battery and showing 0% even unplugged.
Also, in addition to everything above, even though I'm certain it's not a battery issue, I bought another official Samsung battery just because I really don't want an 800 dollar paper weight, and I know the battery was somewhat charged when I got it, and I put it in and have the exact same issue. I also just flashed stock firmware via Odin, same issue. I was able to do all of that with my USB plugged in -- but as soon as I unplugged it the phone turned off. This is so frustrating, I can't explain how much I would appreciate help, and maybe even send some money via Paypal for an answer to a fix.
Does anyone have any idea? Please, any suggestions would be greatly appreciated. I have heard maybe it's the charging port on another site, but that would only explain it not charging, not the sudden and instant drainage of two batteries that were both over 60%. I would really appreciate any suggestions.
It could just be something wrong with the phone itself. Bring it to a tmobile store.
I charged my battery. Took it off the charger and turned off the screen. When I woke up the phone was off and I dead. I am on cm12.1 fairly recent update. I updated a couple days ago. I just want to know if anyone else had this issue?
Only time thats ever happened to me is when I was camping in the woods. Like it was searching for a signal all night and killed the battery.
I had something similar happen to me over the weekend. I mostly use a Choetech Qi charger, and pulled it off the charger Saturday morning before heading out for a day of motorcycle riding. After the ride...~6hrs later my phone still showed 100% battery. As I was catching up on emails etc..the phone just shut itself down. I rebooted...then it shut down again within 30 secs of use.
While it was still off, a quick press on the power button popped up a battery image showing 0% battery. Within 2 seconds of plugging in a charger...it jumped to 100% again. But the phone would not stay on, unplugged at all. I tried wiping the cache hoping that would clear out the battery monitor, but not luck there. The only that worked was turning the phone off, plugging in the OEM Turbo Charger, and letting it charge over night.
Do you have any app monitoring battery usage like betterbatterystats or gsm battery monitor?
sometime obviously kept your usage on while you slept. not normal. either searching for a signal all night, or a misbehaving app, etc. y
I do not have currently have any 3rd party monitoring app. But it's probably not a bad idea. I just think that something with the wireless charging eventually whacks out the battery calibration. As long as I can "reset" everything with a night on the Turbo charger, I can deal.

Radon,
I'm seeing nearly the same problem, but mine is at 80% not 100%. I tried doing a full charge on a standard (non-Turbo) charger overnight, and it changed things, but still not in an acceptable state. Did you try using a standard charger? Or did you only try the Turbo charger?
Verizon and Motorola are telling me I need to do a factory reset and/or get a new phone, but I'm trying to do my research first.
Clear the app cache (Go to Settings->Storage then click on Cached data and hit OK). Then reboot into recovery to wipe the cache there (note it'll take upwards to half and hour so don't freak out if it looks frozen). Then turn the phone off and leave it on the factory charger overnight (or for a while after it reads 100%) with the phone still off. This clears the cruft to fix misbehaving apps, then calibrates the phones understanding of what a full charge is. You also might want to delete any apps you no longer use, especially ad-ridden games, system hook apps like keyboards, and things that track location or status which might keep the phone awake.
After I shattered my screen on my last turbo and got a replacement I've been having issues with my battery. It would randomly die and wouldn't respond or let me turn it on without connecting to a charging cable. Sometimes it goes from a good charge to 39% and turns itself off but often, like I observed today, when I looked at my battery trend it actually went from 75% to 8% in an instant. Not sure what the cause is. Could the battery be discharging somehow??
Hello, lately I've been having some battery drainage issues with my Huawei Ascend P7.
For some reason it drains really quickly (sometimes even when the screen is turned off). Sometimes my battery jumps from 40%+ to 15% and when I plug in the charger, it jumps back to 30%+ really fast.
My phone is rooted, I'm using Doze and Greenify to save some of the battery when the screen is turned off and I also have "Screen power saving" option turned on.
I have taken some screenshots of the battery usage and one of my phone's specifications.
Does someone know what might be wrong with my phone or could there be something wrong with the battery all of a sudden?
Did you try to reinstall Android new?
Or at first a factory reset?

I flashed B852 package's recovery and boot. Then rebooted to recovery mode, wiped data and cache, then rebooted to install mode and installed B852 ROM (dload/UPDATE.APP).
The phone turns on fine, but the battery percentage just drops so quickly and once it even shut off when it was at 60%. When I tried to boot it back up it said it was outta battery.
And one time when my phone turned off and wouldn't turn back on, I plugged in the charger and it told me the phone still had 32% battery. I turned on the phone, unplugged the charger and it shut off in a minute or two. When I plugged the charger back in, it still told me I had 30%+ battery left.
I think the problems began when I flashed https://forum.xda-developers.com/as.../kernel-huawei-ascend-p6s-p7-k-tuned-t3355223 kernel. But I installed a clean B852 ROM and the problem still persists.
Thats really strange, but this kernel is not the problem.
I also have a P7-L10 B852 and using this kernel without any problem...
But right after installing this kernel I also had some strange problems...
Sometime my phone rebooted it self or if it was locked and I pressed the power button to wake it up, it just stayed black and it got really hot...
I don't know what py phone did at this moment because if you are looking at the battery info in settings, it says my phone just was turned off and even lost battery but it wasn't really off...
My solution was a clean install (erasing and flashing every single image and after that 3-button-method)
After that boot up your phone
Now shut it downs install the kernel again
Boot up
Shut downs
(Maybe flash original boot.img
Boot up
Shut down)
Install kernel again
Boot up
I'm using this kernel for more then a half year now and I don't face any problems anymore...
I think the battery itself was the problem. I removed the back cover, removed the battery and cleaned the connector pins with alcohol. When I turned the phone back on about 30 minutes later, under "Power saving" smart power plan option shows me the phone will last for 11 h 30 min at 83% (WiFi turned on), when it used to be like 2-4 hours at 90%. I'll keep monitoring for a while to see if the problem is truly gone.
Thanks for your help.
//edit1: Never mind, I tried playing with the CPU voltages and it froze, so I turned it off. Turned it back on and the problem was back. It jumped down from 80% to 14% and in a minute or two, the battery died. When I booted it into recovery, TWRP says I still have 34% left. So I rebooted into system, it showed me I did have 34% left, but it turned off. Going to try your advice now.
//edit2: Got it to work properly again. Hopefully I won't touch something that will mess it up again.
Maybe your battery itself is the problem but to proof that you will need a second P7 to change batteries of them...
But such extrem battery-problems I have never faced...
You could send it to Huawei support, maybe they will say you if your battery is damaged...
So you could buy a new one and change it
Have you tried calibrating your battery?
I don't think it's a calibration problem
But if you want you could try it...
Charge your phone to 100%
Now delete the batterystats.bin at /data/system
Reboot your phone
Use your phone normally and let it discharge right before it's shutting down it self (3% I think)
Now charge it again to 100%
While charging your phone you should not touch it or unplug the charger
Last night I went to sleep with the battery being at 90%+, woke up to my phone being dead (the alarm didn't go off).
Tried turning it on, it showed me I had 50%+ battery, but it turned off shortly after. I plugged the charger in, and it said I have 58%.
And yes, I have tried calibrating my battery. But I can try doing it again when I get back home from work tonight.
//edit: Battery calibration didn't help. I'll just have to wait until the new battery arrives. Or should I try locking the bootloader?
Why you want locking your bootloader?
Do you want to send it to the support
If you already bought a new battery, wait for it and put it in
Seems that the battery itself was the issue after all. After putting in the new battery, everything seems to be back to normal.
