it's a known problem. Did it occurred while changing USB connection to PC?
for UK retail MotoGP se had an minor update (176.44.1) that should have fix the problem.
Otherwise look in the forum.

charge the device from the mains. It will start going 1 > 2 > 3 etc and then should jump to 100 quite quickly.

No, this problem occurred at no charging ( when I use the device after fully charged by 2 hours )
When I come back to my home I will connect it to charger, and I hope this problem disappear.
Now I check for update and no new update available

It will fix itself (or at least I think or hope it should) when you get it on a good mains charge.
Very well documented error around the net although not greatly on XDA. Mine did it once after a bad edify script execution in CWM but has never done it again.
I was going through thoughts of RMA and all sorts but it was soon fixed.

Hi it seems to be a strange fault with battery calibration on a lot of moto g's ive never experienced it powering off at a high charge level mine sometimes powers off at 10% but not 90% hope it fixes itself for you I understand it must be irritating worrying if your phone is going to stay on.

Happened with me too.
Full charge > connects to pc > battery goes from 100 to 0 > phone switch off > me gone crazy.
Fixed itself though eventually. Hope the same for you @Ghorab :good:

It just happened to me today - from 53% down to 1% while I was connecting it to my PC via USB. Hopefully it will fix itself like others said.

Same thing happened to me today. After searching on the Moto forums for a little bit and seeing that yes this is a very common occurrence I was able to fix it by using it till the battery died then connecting it to a charger.
So to summarize if you battery jumps from a high percentage( >50%) down to 1% just let it die them connect it to a charger, preferably a wall charger and let it charge back to full and then some so the battery can re-calibrate.
Now that I've got that out I wanted to note since I wasn't able to find this elsewhere. With most of the individuals reporting this issue they were apparently connecting to a pc via USB when it happened. I was not. My phone was connected to a wall charger, I was holding it in my hand using it normally as I have for the past several weeks and boom it said it needed to power off due to low battery.
I really do love this phone but I really hope Motorola finishes working out the rest of these bugs soon.

It will not fix itself. It's only a matter of time before it reoccurs.

Battery drop during usb tethering
For me happened two times already in the very moment when I start usb tethering . the phone rebooted and come back with 1% battery. After this keeping in usb port for 3 minutes was back to 100 %. But I cannot share my Internet to a PC anymore and is very frustrating.

+1 for it recurring.
I know it will keep working for hours at 1% until you recharge it, however for all this time it will be cutting back to minimal operation.

Yes, this is true.... The LED turns green on 99% and never touches 100%. But i did not care much about it as I was more interested in flashing ROMS...though this is a problem.... I have also ordered Anker Batt... waiting for the courier...
I noticed mine did this last night. I just kept it plugged in and it eventually hit 100%. I took about 9 hours for it to hit 100%. Hope its not like that every time. Ill be finding out tomorrow.

well it hit 100 even when the led was green
I've noticed that the discharge is also a bit strange even on OEM battery. My battery varies very much. Sometimes when I reboot I get 5-10% more juice after boot without putting it to charge

yes same here....what can b causing it.....can it b smthing wrong in s-off procedure
Could it be something to do with the 2.3.3? Cause my battery acted strange even S-ON so I don't think it's the S-OFF procedure itself that caused this. Might be something something to do with battery drivers or something?
AFAIK Li-Ion batteries should never be charged to 100% because it shortens their life, most phones have a safety-mechanism to prevent overcharging.
Its intended to stop charging at 95% to 99%, but will almost always show that the battery is charged to 100% so the customer wont complain about it.
yes HTC is lieing to us, but for our own satisfaction.
So after we flashed the CWM recovery this "feature" is not there anymore and we can see the true charging state.
By plugging the power in and out over and over again to reach 100% you just damage your battery with those short charging cycles.
I read a interrestion thread about it in the Nexus S forums awhile ago and Wikipedia seems to confirm it.
I hope I could help you.

[Q] AT&T Nexus S - Insane battery drain for no apparent reason?

I have had this Nexus S for nearly two years and recently I ran into an issue with the battery draining BIG TIME for no apparent reason. With any sort of use, the phone will die in 1-2 hours. If it sits by idly doing absolutely nothing, it will go from 100% to dead in ~6 hours.
It is bone stock - never been rooted. It's running on 2.3.4 GB at the moment. I have completely wiped it and set it to factory default. There are no apps installed, no accounts synced up but the drain continues. I even swapped it with a brand new battery and it still does this. Would anyone happen to know what I can do to fix the issue? The phone does have a few scuffs but it has never been severely dropped or gotten wet. It seems to have just started doing this on it's own.
This is the phone after a 100% charge and full wipe. It put it next to me and did not touch it at all. It was down to 50% after about 4 hours.

I'm no expert, but it looks like you don't have WiFi connected, and from your picture it appears that your cell signal is so weak that its only intermittently connected. When the cell radio has to work that hard constantly to maintain a connection, it will drain the battery very quickly.
On the other hand, if you're stock and unrooted, the phone should be prompting you to update the OS to 2.3.6, then 4.0.4., then 4.1. Any of those may cure whatever is currently ailing it.

I have checked, there are no updates. I think AT&T pushes them out. The phone is stuck on 2.3.4 either way.
There is no SIM card in it. It is not looking for a network at all. True, WiFi is turned on but I seriously doubt that it would drain battery from 100% to 0% in a matter of hours with the screen totally off.

[Q] Please Help!!! Battery shoots up automatically.

I usually flash custom roms on my device. But my device has one unusual behaviour. When I charge my device and suppose it is 70 percent charged and I reboot my device within 20-25 minutes, the battery level shows fully charged. (100 percent) After that the battery drains within 2-3 hours. Because of this I charge my device 3-4 times everyday. This happens on every custom rom I install on my device. Should I change my battery or is it the device's fault? Please help.

the percentage increase after reboot is a htc common issue while charging
about the fast drain maybe your battery is dying or doesn't makes contact properly
check it
Thanks for providing this useful information. Do you mean using paper or something that holds the battery tight or I misunderstood something.

exactly that
use something to hold the battery and see if you still have reboots
Actually I think the paper solution won't work. He's not having reboots, just the battery is draining fast. It looks like that your battery is almost died. I think you should buy a new one. And I highly recommend Anker's one.
Thanks once again. Will try.

I didnt want to make a new topic but I have similar problem:
i switched from standart ROM to Cyanogenmod 10 nightly builds for my Sensation Pyramid (original battery, about year old).
Everything worked fine, but there is one more than annoying problem:
I charge phone to 100%, i pull charger out. If i use standard things on phone (settings, gallery etc) everything seems to work fine. As soon as I enter any applications (Twitter, Facebook, default Web Browser) it just shuts down in 20seconds or in 2/3 minutes (always some random time, i can browse web 10 seconds, it shuts down, sometimes i can do the same for a minute and then it shuts down), it doesnt reboot just shuts down.
When I turn it back on, it shows battery level ~ 9-15%. It was 100% just 3minutes ago. I charged it for hours before, so that 100% should be real. I tested with battery drain monitoring app, when i use any apps, battery drops for like 1200% every minute. Its Ok on standby mode.
When i just reboot the phone, it comes up with some random battery percentage, f.e 47%. So it can go from 100% to 7% and after reboot it goes to 47%.
I thought it might be a ROM problem, so I installed this albinoman887 ROM http://forum.xda-developers.com/showthread.php?t=2115520
Did factory reset, cleared cache, phone was 100% charged. But the same problem.
I dont thin its battery problem, because it was OK with stock ROM. Is there anything i can try to fix this problem without going back to stock ROM (or other Sense based ROM)?
Here is a screenshot from my "About phone" section:

Really no advice on this?
Im not so good with Kernels etc., but my guess is- maybe this has something to do with CPU usage? I checked with CPU Spy app, it says Internet explorer, other apps use 1566MHz. Isn't that too much?

Do I have a bad battery?

So... Starting yesterday, about 5:00pm, my battery started charging extremely slow. I plugged my phone back up since the battery went down pretty quick at about 9:30am in the morning. It went to 30% battery and from there, I don't view if it's going up anymore. I took a screenshot at 9:42am and once closer to 10am, also taking another as I typed this. I've also tried 2 different chargers, and multiple outlets.

@rootSU, sorry for tagging you. You just seem to be extremely helpful, and reliable. ?
The last screenshot, I just hit 31%... Literally changed when I clicked the battery tile.
When you tried multiple chargers, did you also try different USB cables?
You need to rule out if it is slowly charging or if it is draining quickly whilst charging. Try turning it off and charging.

I attempted that yesterday when I first noticed it yesterday. I plugged it up, and left it off while I went to the market.
I left it plugged up, and I'm now at this from earlier.
I'll attempt that now with another cable.
I'm now at 100% after letting it charge while off.

The device is still doing doing it. Seemed to charge faster from USB earlier, but now it seems to be back where I was earlier. I'm starting to think that maybe the charging port is the messed up part of the phone.

This is why I asked you to charge whilst off. It rules out software as an issue if the same result is seen. If you've changed the cable AND power source, it can only really be the port.
Is it stock unrooted?? Does seem like the kernel gets involved in charging whilst off too , so if you're not stock, I would consider reverting to stock.

I swapped back and fourth between cables and reboots after returning to stock. I went to stock 4.4 and upgraded all the way through. I then noticed it started to charge faster, or the battery actually read that it was going up. I had Current Widget on my home screen which seemed to be pushing around 900MaH the whole time.
For now, it's back to normal, I believe. Thanks RootSU ~:good:
is it back to normal?
my phone is doing the same take forever to fully charge but i dont know if its the battery or the port

Sorry for the late reply, it I've downloaded CurrentWidget where I can see the mA output. The OEM charger seems to be pushing out at 20-300mA. I've plugged up yesterday to an old HTC cable that I have, and although it's all beat up and near its end, it's pushing out 300-600mA.
I believe the original OEM output is near 1000mA. Possible that it was my charger that was faulty. I've been using a lot of different chargers in the past week testing with the mA's.

Battery Stuck at 100%, Turns Off at 50-60%

Hi,
I'm facing a serious issue with OPO's battery. Don't know exactly when this started to happen, but I'll give you as much details as I can.
Few days ago I was unplugging OPO from charger around 8PM with 100% battery, I felt asleep and in the morning, 12 hours later (around 8AM) the battery indicator still at 100%. I thought this is awesome battery because I turn on Wi-Fi and sync on, even though I don't touch the OPO even single time before 8AM. Few hours later battery drops normally, around 1% to 3% per hour. Until it reaches 50% to 60% when OPO turns off suddenly. When I plug the charger back, I read that battery level is too low so I can't turn on the device. But a few minutes later (still charging) I can turn on it again and strangely battery level is still at 60%. this cycle keeps happening when I charge it back to 100%, later it will turns off again around 50%-60%.
Yesterday I brought my OPO to a repair service branch in Jakarta, Indonesia and I specifically ask to replace the battery with a new one. But their representative rejects it and offer to take it around 3 weeks for repairs, with the risk of losing all my data (I guess because they want to factory reset my OPO). So I reject it (seriously 3 weeks?) and brought it back home.
I have this feeling that it's a hardware issue (the battery itself) rather than software issues. Because it's happen a long way after I upgraded OPO to Lollipop (forgot the codename) and still happen on the latest OTA release. OPO itself is not rooted and I use stock CM ROM.
Seriously need help. Thanks in advance and sorry for my bad English.

hi there, we got same problem here.
my baterry is stuck at 100%.
and would suddenly turnoff at 40-60% .
i think this is not a hardware issue,
but software indicator issue.
hope someone will answer our problem here.
i ever read that we should let it charge without turn on the phone for over 3-6 hour,
they said it would reset the batery indicator.
i haven't test it yet.
if it work, please inform me.
sorry for my bad english too~
I got you both covered.
It's just the calibration problem.
You need to be rooted for this. Go to /data/system/batterystats.bin and delete the file. Turn off your phone and charge it uninterruptedly. Done!
Or
You can use a battery calibration App, both of them work the same way. But you need to be rooted. Cheers!
Attaching a screenshot of the file.
