[Moto G Q&A, Help & Troubleshooting] Narwhal73:
This just happened to me. My Koodo/Telus Moto G was charging using a wall charger, and shut itself off. Battery was at about 95% or so and drained. Boot up showed 1% battery. I left the phone plugged in and it was back up to 100% within 21 minutes of charging. This leads me to believe the phone actually didn't die and it is a battery calibration issue (as previously mentioned).

This was using the stock Canadian 4.3 firmware, locked boot loader, no root. I plan on contacting Motorola about this issue tomorrow.

Screenshots of battery history from Battery Widget Reborn Pro, immediately after the drain and after full recharge.

Today I was charging via USB port on a set-top box. Phone started to lag as if CPU speed was set really low. Phone also rebooted a few times within 10 mins.

I wonder if these issues are related, and specific voltages are the trigger.

Can people try connecting their Moto G to USB ports on different devices and report back.

Yesterday try my Moto G on one STB - it was charging normally without any issues. Just the current is low as on a USB port, not like a wall charger.
[Moto G Q&A, Help & Troubleshooting] anerik:
The issues seems to be fixed for me. I did a cwm backup and then the battery was drained like 20%, which was weird, but when i charged it with the charger it charged normal, i left it for 2 hours or so. No issues so far
[Moto G Q&A, Help & Troubleshooting] lost101:
Using a generic USB cable today. Along with previous problem, I just had a white 'battery error' screen appear. Had to turn phone off and on. Battery was 20% before and after. This time I was charging via wall plug.

I've noticed some cables don't work at all, but now I see some make the phone freak out.
[Moto G Q&A, Help & Troubleshooting] Narwhal73:
This happened to me again this morning at 5:30ish when I was sleeping (as a consequence I missed my alarm... Oh well). Once again the Moto G XT1032 was running stock 4.3 (locked boot loader) and it was charging overnight from a wall charger.

Battery history is attached in the screenshot. I received the KitKat OTA today, so hopefully this issue will stop happening. I'll report back again if it does though.

PS. I also reported the issue to Motorola through the Moto Care chat, they were rather useless, though they say that the chat log was saved and will be hopefully be seen by the developers working there.

I have some logcats if anyone has the expertise to investigate this.
[Moto G Q&A, Help & Troubleshooting] samijam:
I've been reading through this and it seems that the trigger for many(not all) people is unplugging from USB. For me, however, this happened twice yesterday when plugging into a wall charger. The first time, the battery was at about 70% and I plugged it in and then it immediately shut off and then was charging only, with a reading of 1%. After maybe 20 minutes of charge it was up to 100%.

I was using the white USB cable that came with the Moto G plugged into an LG wall adapter; 5V, 0.55A (from my LG Optimus L9 P769)

This Moto G is the XT1032 8GB - Global GSM running android 4.4.2
[Moto G Q&A, Help & Troubleshooting] lost101:
If the Moto G hardware is very sensitive to voltage / current changes; that might explain why it could happen at any time, but is especially likely when charging. This is assuming it's possible for voltage / current to change when handset is not connected to anything and without user intention.

---------- Post added at 02:17 PM ---------- Previous post was at 01:35 PM ----------

Just happened on 4.4.2. I was installing new kernel, and had done a dalvik-cache wipe. Phone was connected to PC via USB. When phone rebooted after flashing kernel, and was booting up (apps upgrading dialogue) battery dropped to 1% and phone shutdown. In less than 10 minutes connected to wall charger, phone was fully charged.
[Moto G Q&A, Help & Troubleshooting] michalurban:
It has never happened to me fortunately but Im pretty scared this could happen when Im in a need of taxi during night somewhere, anybody heard anything from Motorola regarding this?
[Moto G Q&A, Help & Troubleshooting] lost101:
The person I talked with at Moto Support just said return it to repairs; which isn't an option for me. I don't think Motorola will take it seriously until there is enough evidence collected on here, and even then it might require a Verge / Engadget story.

Almost 50% of the people that have voted in the Poll so far have experienced this. The problem is real.

don't worry about that scenario. it is able to run the same time afterwards as if nothing happened. the problem is that it switches off and you have to manually power it on and the % shows 1 until you connect a charger

the same problem happened to me yesterday, when I switchted mtp connection off while connected to my pc.

Can reproduce this error, every time I switch the mtp connection off, the battery drops to 0 or 1 %,

but the devices won´t shutdown.

AND I could use my Moto G after this for at least 15 hours with 4hs sot,

Bingo! :)

Reproducible here also. Drop to 0% and reboot. UK device running stock 4.4.2. Unlocked bootloader. Rooted.

Can some other people please try to reproduce this bug:

Connect phone to PC (or maybe laptop?) via USB, and enable disable MTP mode.

I had this issue when I first connected my Moto G to my computer.

However, I can not reproduce the issue by switching MTP on and of while connected to my computer. (the device disappears and reappears from the "my computer" view, as expected, but no battery percentage drops...)

Now I am unable to reproduce the bug since rebooting phone.
[Moto G Q&A, Help & Troubleshooting] AndroidInsanity:
I connected my moto G to a wall socket charger. It jumped from 32% to 61% in like 5 minutes. I really hope Motorola fixes this bug don't wanna return it :(
[Moto G Q&A, Help & Troubleshooting] lost101:
Considering the random nature of this bug, I doubt Motorola will ever fix it. Here is a thread on the official forum that they might pay attention to:

https://forums.motorola.com/posts/b08e287fc6

Unless an XDA developer solves it; the best solution might be to use a non-stock based ROM like CM11. That's assuming the issue is caused by something in the Motorola stock firmware.
[Moto G Q&A, Help & Troubleshooting] AndroidInsanity:
Well it seems like a calibration issue which means software issue surely. I wonder if calibrating the battery with a app will fix it.
[Moto G Q&A, Help & Troubleshooting] miklosbard:
it's not a calibration issue, but sensor configuration or fpga. in my opinion it can be corrected from software, but a simple rom change won't help unless they focus on correcting this issue

I just got my Moto g 16gb, charging point of view seems to be OK.

I used the cable provided and a USB wall socket too (from Lumia 520), both ways works fine, so far.
[Moto G Q&A, Help & Troubleshooting] michalurban:
Do you believe that CM would not have this problem? Why? They must be taking some hardware-related stuff from Motorola - or am I mistaken?

Does this mean this could be generally easy or rather hard to solve it?
[Moto G Q&A, Help & Troubleshooting] lost101:
I hadn't considered that, you are probably right. And if miklosbard is correct, CM11 would also be affected.
[Moto G Q&A, Help & Troubleshooting] miklosbard:
I wanted to write or, not of. (corrected original post)

The easiness of the solution depends on a lot of stuff. It can be just a mishandled signal that takes 10 sec to correct or a totally wrong implementation that needs refactoring. worst case scenario is that they put together two hardware that are not fully compatible, but that would be a huge design fault, so in my opinion it is not the case.

[Moto G Q&A, Help & Troubleshooting] lost101:
The difficulty is convincing Motorola to do something. If you contact support, they tell you to send it to repairs. If you do that, it's likely they will find nothing because it's not always possible to reproduce the issue.

Maybe if everyone here who has experienced this problem also posted on the official forum; they would take it seriously as it may risk future sales.
[Moto G Q&A, Help & Troubleshooting] Narwhal73:
This had happened to me for the third time. It happened twice on Jellybean and now once on KitKat. All times it has happened when connected to a wall charger and the battery percentage was above 90%. Happened twice while I was sleeping and once while browsing Chrome.

Dont get this Issue, and i tried it several Times with different Cables and modes.

Maybe it's really just a Calibration Thing. What i did after the Update (The typically drop from 100 to around 50%) was to drain the Battery empty, recharged it to 100%. Then i removed the batterstats.bin (Which wasnt deleted automaticly), which i do everytime when updating or installing a Rom.
[Moto G Q&A, Help & Troubleshooting] eddvys:
I had battery drain from 97% to dead% I plugged phone back to charge. Turned it on wait for 3 minutes and then restart the phone. Battery mysteriously came back to where it was to 97%. Poltergeist or what ? :))

I tried debugging mode off and phone Turn off and 1% battery is back.
[Moto G Q&A, Help & Troubleshooting] scott_doyland:
That batterystats.bin file is irrelevant, read the link below. As you may know Diane Hackborn works for Google and actually wrote the code that uses that batterystats.bin file.

As she says in the last paragraph of her first post in the link, that file is reset anyway after a charge.

I believe CWM used to have a function to delete the file but actually removed the function after Diane's post.

so this should be an hardware or software issue? as not everybody are having this problem this should be an hardware problem, replacing the phone should fix this right? i bought this phone 7 days ago and i have 3 more days to have it replaced from seller, should i do it? i really wouldnt actually
[Moto G Q&A, Help & Troubleshooting] lost101:
Based on the poll so far, more than 50% of people have experienced this issue. I don't believe any handset is immune; and people who have never had this problem, don't connect their phone to a PC/Laptop very often. The majority of the time, connecting to a computer USB port will trigger it.
[Moto G Q&A, Help & Troubleshooting] raniero1:
actually people who look for and read that poll/post should already had this problem, and actually just 37% of people according to that poll had the problem, this mean on a 63 people base just 23 had the problem vs 40 that never had it, i think this poll is not pretty much relevant but if it is it saying the most phone are free from this issue, in addiction to this people reading and writing in this forum should be pretty much more than basic or average user and i suppose at least connect the phone the pc usb.

I dont want to say that this is an hardware problem, i woul really prefer its a software side issue that anybody have and that would be fixed, but im looking forward to know what to do, as now i still can replace the phone but i would really avoid this way. if it is an hw problem i should so if somebody has any idea let me know. but i guess that as this thread is almost 2 month old and we r still talkin about it there isnt any real information about it

battery problem

I faced this issue last friday when connected to laptop. Motorola customer care asked me to try this

1. leave to drain and make-2-3 full charging cycles

2. if after this the problem persists, I would advise you perform a factory data reset on the phone

They mentioned it might also happen because of apps crashing. So then i pointed them to this forum. Except for this battery problem and Chrome flickering in tabs view i have not seen any problem. As with many users i am confused weather to get a replacement or wait.
[Moto G Q&A, Help & Troubleshooting] scott_doyland:
But only people who have battery issues even bother to look at that poll. You will probably find its like 1% of all phones that are really affected, probably less.

If it was 50% of all phones I think Motorola may have discovered the issue during their own testing.

That's a fair point. I guess with time we shall see how common the problem is.

It happened AGAIN. Fourth time so far, twice on the official Telus/Koodo KitKat with no root, locked boot loader. Every time the Moto G has been plugged in and charging through a wall charger from the Samsung Galaxy Ace. I'm thinking of getting a new (higher voltage?) charger to see if that helps fix the issue.

I got a similar problem on monday

- I woke up and disconnected (as I do everyday) phone at 7am from AC charger (not usb)

- Arrived at office, etc. and at 12:18 I heard the lightflow sound alarm for low battery. I used the phone just for few things that morning

- I was able to take a screenshot while phone was shutting down!

- I turned it on again, and kept phone at 1% battery until 1am I went to sleep. I left spotify open until battery went to 0 and phone went off

- Yesterday I put it on AC again and all looks normal again

[Moto G Q&A, Help & Troubleshooting] kiiruchu:
Same issue here.

Happened to me twice on 4.2 and once on 4.4.2.

The first time it happened I was on my first charge. It just died around noon going from 90% to 1%.

I chatted with Motorola the same day and agreed on keeping the phone to see if the problem solves itself when the battery gets a chance to calibrate itself after some cycles.

The second time it just died some time during the day again, but today's battery drop was just ridiculous:

I charged the phone to 100% on my laptop overnight, then in the morning I used it without unplugging it, when it suddenly died. It automatically turned back on again, because it was still plugged in and after a couple of seconds it jumped back to 100%.

The phone is from o2 in Germany, it has 8gb of storage and stock 4.4.2 firmware.

The problem does not occur in three out of four charges, but I will try to send it back to Motorola now, because the battery did not manage to calibrate in a month now and I really don't want to keep a broken phone. I will report back what support tells me.

edit:

I reset my phone the first time my battery died and did not backup the screenshots unfortunately, but I still have screenshots from the second and third battery error.

Second error including recharging curve:

From 66% to 1%

Hi there.

Yesterday I put my phone in aeroplane mode and I went to sleep. In the morning alarm didn't wake me up. I discovered that my battery was dead. Or so phone was reporting. I charged it to 7% and then to 33%. And it's still 33%.

I didn't have any usb cables plugged in. It just happened during the night and killed my alarm clock as phone was dead. <- is this normal? Phone completely turned off. It woke only after I charged it the first time to 7%.

OS 4.4.2 OTA -> after OTA I've rooted.

Should I return my phone (And I thought battery was fine and therefor I rooted it :p ) or is there some sort of calibration prcedure for this kind of behaviour?
[Moto G Q&A, Help & Troubleshooting] jim.1405:
I've had the same thing happen and have seen enough posts in the various the battery threads to conclude this normal for the Moto G. When it happened to my first G I returned it and got another. While completely shutting itself down hasn't happened yet on the replacement, there is something flaky with the battery level reporting. It will go from say, 94% one minute, to 17% and minute later, then back up to 94% in a few minutes. It is truly unfortunate this phone has this flaw because otherwise it does get outstanding battery life in my experience. But, I would never rely on it for an alarm if I needed to get up or in any other mission critical situation. It is just too unreliable.

This seems to be a very random problem ive charged my moto g in the car and off the wall charger my battery drops steadily as it should I haven't experienced this issue owned my moto g for almost 2 months used mime until it ran down when I first got it.
[Moto G Q&A, Help & Troubleshooting] borisblank:
Well, this battery power drop is now a daily event for me. Started off as once in a couple weeks, now its every day. USB mains charger, phone beeps, shuts itself off and charger screen appears showing 1%. Needs to be fully "recharged" for hours until. Phone shows 100% charged even though it already is.

Tried all the tips in this thread but problem persists. Also the little battery icon at top right sometimes shows that the phone is charging when there is no charger attached!

Fed up of this now, gonna have a moan at Motorola and ask for a new phone. I know that chances are the problem will still be there on the replacement but Motorola will ignore the problem unless they keep getting phones returned to them.

Really hacked off with this daily farce!

My Moto G already did this twice, the first one from 26% to 0% and the second (today) from 50% to 0%, but this time, after charging for 20 minutes it was already 100%, the other time it took at least 2 hours to get to 100%.

Used the USB cable on PC only once to transfer files, but the problem happened 2-3 weeks AFTER this. I only use the wall charger to charge the phone.
