Battery drains on connecting to PC.

For me battery drains from x℅ to 0℅ whenever I connect my phone to PC using USB. The phone automatically switched off and on restarting it shows 1℅.:confused:
[Moto G Q&A, Help & Troubleshooting] uriah18:
Joining the club.

XT1032,16GB, sigle SIM, stock KK, went overnight from around 70% to 1%. I connected it to charger and it charged back to 100% in about 30mins. I kept it power off until 15%, turned it on to see what happened, and then power off again until fully charged.

I will post to motorola forum also.

I basically do not connect phone to PC. I am always charging it with nexus7 charger, but the other day I connected it to htc charger by mistake and after few minutes I changed it back to nexus' charger. Maybe it has something to do with charging on various chargers?
[Moto G Q&A, Help & Troubleshooting] quizmaniac:
Its only happened to me once and that was a month ago,went from 74% to 1% and shut down,i just turned it on and used it showing 1% for a few hours until i got home.

no problems since and i charge up mostly from the mains using a HTC charger but occasionally from the laptop.
[Moto G Q&A, Help & Troubleshooting] tawke:
I encountered this problem last week so after reading about it on this thread I let the battery drain until shutdown then fully charged and it returned to normal. I managed to replicate the problem today, by accident, but seem to have fixed it by putting my case on backwards...

I know that sounds silly but it made the phone turn off then boot in fastboot mode. A reset later and the battery indicator showed as normal. I wanted to try it out again but I can't get it mess up any more.

So if someone wants to try that...

Update from Motorola:

We know this is frustrating and apologize for the experience. We are working closely with Qualcomm to confirm root cause (which we believe is an intermittent error in a sensor measurement) and we are testing algorithm adjustments to filter out any spurious measurements. The phone is shutting down in these instances as a protection mechanism based on this incorrect measurement.

All of the diagnostic data we've examined shows that the battery of your devices is okay - indeed this is why you can continue to use the phone at "1%" - because the battery still is really charged at whatever level before the abrupt drop.

We are testing this adjustment now (better filtering) for the next system update. We know this is frustrating, both for the folks for which this appears to occur randomly, as well as those for whom it is fairly repeatable (USB). Thank you to the users who have swapped units so that we could examine them - the occurrence of this in the *total* Moto G population is very low, but that doesn't matter if it is happening to you!

We'll share more data here as soon as we have it; unfortunately exact release schedules for updates depend on several things (carrier lab approvals, etc.) and this is not the only item in this release. However it is a priority to get out and we are testing algorithm adjustments now.

Wall Plug Issue

This problem occurred with me after I unplugged from a regular samsung galaxy s2x wall charger. I charged my phone to 96% then once it hit 89% it dropped. I think this is a calibration issue. You must leave your phone plugged into the wall outlet for about 3-4hrs after the phone reached 100% to make sure the sensors are calibrated. I think I will return my phone just in case, however, if i get the same issue I will do the wall outlet potential fix.

I didn't want to read through all 11 pages of posts, just wanted to confirm this is also a bug with the google play edition. When USB type is set to MTP, bizarre things happen with cheap chargers, Macs, linux, etc. Hoping for a fix soon.

Quick fix for now: Disable MTP function when not actually using it. This seemed to fix it up for me for now.

Incorrect.

And it happened again this morning. Fourth time now.

A couple of weeks ago I tried the so called calibration procedure and thought it worked because all went well for a couple of weeks.

Unfortunatelly this morning it dropped from 97% till 1%. The phone was charged the evening before and was not used in between.

So this calibration thing did not help in my case.

Hopefully Motorola will have a solution soon.

I've only had my Moto G for about 10 days but in the past few days I've been experiencing the 1% battery problem almost on a daily basis, I'm extremely loath to send it back because I need it plus it was bought in the UK and I live in France, and of course there is as of yet no official fix anyway.

In the meantime I have at least discovered a way to get it to read the battery properly again.

Turn the phone off

Press and hold power and vol down together for two minutes MINIMUM !

When you release you will be in the boot menu.

Press vol up and the phone will boot normally and display the battery correctly - until the next time !

Let's hope the promised proper fix is not too long in the coming.

I'd like to post a of screenshot of the battery and near instant revival but as a newby I'm apparently not yet worthy :silly:

I can say that no fix for this problem has ever been rolled out.

I have a european version updated to last available firmware (4.4.4 210.12.40.falcon_umts.EURetail.en.EU) and this problem appeared some weeks ago after almost a year of perfectly working device.

In my case there is not a solution, is totally random and the phone switches off itself more than 3 or 4 times a day. In 2 cases it wasn't even charging, it started to turn on when plugged then die and turn on again. I had to unplug and replug hundreds of times before it started charging, and after charging to 2% it jumped to 100%.

Sometimes it just die and refuse to turn on for some hours, then it turns on withe correct battery level.

In 2 words, is ****ed.

I'm thinking about asking a new device but it seems a software or firmware problem so i fear that the new device will start acting like this too....

[Moto G Q&A, Help & Troubleshooting] FoneWatcher:
I've had a Moto G Xt1040 4.4 that this has been happening to for over a year. I leave it plugged in on a cradle as a bedside clock/alarm so it is *always* plugged in and at or near 100% charge. Every few weeks I will notice that the phone is black, won't boot and doesn't react to being plugged in.

I've tried the battery removal trick, the higher amp charger trick, 8 hrs. charge/2 hrs. charge trick, deplete battery trick, the hold down power and volume trick, etc. and*nothing* changes the behavior of dying every few weeks except this:

I leave phone unplugged for a day or two ( discovered the first time getting it ready to scrap on eBay).

Second day, the white LED will come on when plugged in, leave it plugged into charger for overnight.

Third day, unplug from charger.

Fourth day, plug back into charger and voila - the screen lights up showing 100% battery graphic and it boots normally like nothing happened... until next time.

[MENTION=4472553]FoneWatcher[/MENTION] - There is a possibility your installation of Android has become corrupt and fastboot flashing the factory firmware image will resolve your particular issue.
[Moto G Q&A, Help & Troubleshooting] FoneWatcher:
Thanks for suggestion, tried that, flashed factory image stock - same thing, then flashed factory image w/root - same thing happening, but there is a change: happening more frequently, with every power down it stays dead whereas it used to last for several days/weeks and survive restarts. Currently dead and trying to revive again to clear my data.

I'm thinking it has to be hardware at this point - maybe a bad circuit on the mobo that reads battery charge? Maybe in the battery?

I was using it as a dedicated music player that lived in my car, but Moto Gs are so cheap now I'll maybe just grab another XT1040-45 from eBay.

[MENTION=4472553]FoneWatcher[/MENTION] - Your issue is not what this thread is about. The problem this thread is related to was patched in Android 4.4.4.

When you say you flashed the firmware image - I need to see a log of that process. Copy and paste command prompt. Take screen-shots if necessary. Fastboot is not user-friendly, and will often completely fail, despite looking like it was an amazing success.

EDIT: If your bootloader is unlocked and for best experience, try the XT1040 5.1 Optimized ROM from here: (Follow flashing instructions exactly)

I don't have the phone but from personal experience charging via a PC port USB takes forever. Also if you're leaving data on and everything, the phone continues to suck more power than it can charge from the PC's USB port.

I suggest a 1000-1500 mAh wall charger.
[Moto G Q&A, Help & Troubleshooting] vuo:
Something similar has happened to me. Went to bed with it at 49% and found it off in the morning. Checked the battery stats and it showed a similar pattern of dropping to 1% suddenly within a few seconds. I didn't have it plugged in via usb at the time or prior to it happening.

Weirdly though, after turning it back on without charging it, it's been working for hours on the reported 1% remaining. I've played games, watched YouTube, browsing, and it's still saying 1%. I think I'll keep using it until it turns itself off as it seems it might be a calibration issue as there's obviously a lot more than 1% of juice. Then I'll charge to 100 and see if that fixes it...

For the record, it's rooted via the modified recovery method. Which makes it worrying about how to return it if it's a battery problem. It's only 2 days old and on its very first charge.
[Moto G Q&A, Help & Troubleshooting] Kenneth131:
Out of curiosity have you guys having issues on set up chosen to restore setting from a previous device. You know on the set up screen after logging in and it gives you the option to backup and restore.

Reason I ask is I had similar issues and after a restore to factory and unchecking the second box on that setup menu I have ceased to have these kinds of issue.

I know it shouldn't but as I mentioned on another thread it appears somewhere the restore feature trys to restore more than just apps and wallpapers. It seems with this feature selected it imports some data that screws with motos power management on this phone or is incompatible resulting in some bizarre behaviour.

I factory reset the phone and unchecked this option did not use moto migrate although I think the later appears to be fine to use, and just manually set everything up.

Since I have had no real issues only minor sw bugs in the ROM which will get a fix
[Moto G Q&A, Help & Troubleshooting] vuo:
For me, I didn't restore from a backup, I set it up completely from scratch and did a factory reset after rooting it.

As an update, my phone is still on the 1% it dropped to, even though I've been using it a lot throughout the day, so it's obviously something to do with the reading the battery level that's gone wrong. I'm hoping once it eventually runs out and I fully charge it that it will not happen again. Fingers crossed it's not a hardware sensor problem.
