[Verizon Samsung Galaxy S 4] gbonawitz:
OK, I know this is a very basic question, but with Google I can't find a specific answer.

When I go to connect my S4 to my computer via a USB hub, the computer doesn't see the phone at all. However, if I disconnect the hub from the computer and plug the S4 directly into the same USB port on my computer that the hub was connected to, it works (i.e. the computer sees the phone).

I know the first thought is that the hub is bad, but I can plug in a thumb drive to the USB hub and the computer sees it fine.

FWIW - it's not an externally powered USB hub - it only plugs into the USB port on the back of my computer. I don't know if that has anything to do with it (although I still wouldn't understand why everything works fine going direct from the phone to the USB port on my computer).

:confused::confused::confused:

Thanks in advance...

Yesterday I experienced a weird behaviour...

I was using my Moto G and it was with 74% battery. I connected it to my macbook using the usb cable and when I disconnected it the battery instantly dropped to 0% and the phone turned off!

After that I charged it again and so far so good. But I wonder what could have caused this behaviour?

I have never saw something like that before.
[Moto G Q&A, Help & Troubleshooting] jojosch93:
I had the same problem a few hours ago. It suddenly dropped and shut down itself. I started the phone again and it is still at 1% since 5 hours. I guess this is related to a bad battery calibration because I've unplugged it during the first charge for a moment (I have the phone since yesterday).

i used to have the exact same issue with my Galaxy S2. it would freeze and then reboot or i would have to force restart only to lose about 50% battery. when i sent it back to Samsung, i think they replaced a circuit inside.

[Moto G Q&A, Help & Troubleshooting] SilverScooby:
I had exactly the same issue yesterday.

I had the phone attached to my Win 7 laptop with USB cable (in USB debugging mode)

When I took the cable out the battery went from 52% to 0%.

I was using the white USB cable that came with the phone, have the official Motorola Device Manager which installed Motorola device drivers v 6.3.0. The USB ports are all v3.0

As this issue happened to 2 of us when detaching from USB ports, could something weird be happening like the phones battery is somehow being drained and trying to charge the laptop's battery? Or could the USB cable be faulty?

I believe it is an adb / usb related bug in the stock firmware. A new rom will probably fix this. Unless someone wants to report it to Motorola.

Had this problem and how I fix it

Hi, I had this problem to. Actually the solution that Motorola gave me was: clear the cache, if doesn't and do a factory reset.

It no surprise that none of those solution did not work. So I decided to use my phone that was showing 1% battery till it shut it self off.

It did take some effort to do it (great battery), so I set brightness at it full, set screen timeout to it maximum, turn on wifi tethering and start to run benchmarks like crazy.

It did take some time and effort and the phone finally shuts down with a battery level of 0% (extremely dangerous for the battery life); plug it to an wall charger and the screen shows charging and battery level stuck at 0%; after 10 minutes the motorola logo shows up and then the charging screen again but this time battery level was 2% and start getting up.

After the battery hits 10% I decide to turn on the phone and was happy to see that the android shows the battery with 10% and charging.

Here is my screen shot of my battery status:

Of course I'll try not to connect my phone to a computer via USB cable.

I'll report battery life after a full charge plus reconfiguration of my phone thanks to motorola and the factory reset that they made me do.:rolleyes:
[Moto G Q&A, Help & Troubleshooting] borisblank:
I tried this as well, from memory the phone seemed fine for a couple days then the battery drain problem started up again. I don't think its a problem that we can workaround, I would suspect its a bug that will require a firmware update to correct.

---------- Post added at 04:43 PM ---------- Previous post was at 04:34 PM ----------

Sorry, I only just noticed your message.

It was left overnight on an HTC charger but it doesn't have to be left overnight, whenever it reaches 100% fully charged it then shuts down and you end up with the 1% screen. The problem only occurs when the phone is attached to the charger. My phone also sometimes reports as "Charging" when in actual fact the phone is NOT attached to the charger!

On advice from Motorola, I then used an official Motorola charger (with a 3rd party cable) but still the 1% problem remains. I'm now using an official charger and an official cable to see if the problem still happens - I'll post the results in a couple days.
[Moto G Q&A, Help & Troubleshooting] Tag49:
I have the same issues.

After performing the update 4.4, I had the batterie drain problem in airplane mode during night.

In 4.3, I was losing 1-2% battery in 7-8h durint night.

In 4.4, about 1% per hour !! :crying:

All google services, location, etc. are disabled.

I did a factory reset + cache partition reset.

Everything was going pretty well. I connected my phone to my PC with a standard USB cable.

Then I unplugged the phone from the PC to connect to a wall socket with the official cable.

And this is where I went from 30% to 0.

Very annoying...
[Moto G Q&A, Help & Troubleshooting] Narwhal73:
Previously, using the official charger from the Samsung Galaxy Ace, I had experienced this battery drain bug four times within the space of the first two weeks I had owned the Moto G. I bought a Nexxtech* single USB AC charger just under two weeks ago (at the suggestion of the above quote), while using the official Motorola charging cable with this adapter, so far I have not experienced the battery drain bug.

The specs of the Nexxtech adapter are as follows:

Model number: AC11116A

Input: 100~240V - 50/60Hz 0.5A

Output: 5V -- 2.1A

Can anyone confirm that using higher voltage wall chargers does indeed help (or chargers with similar specifications to the ones listed above)? I would think that the Moto G is really sensitive to lower voltages/amperages (hence why I had this issue with the old lower voltage wall charger, and why some people have issues with charging through a USB port).

*Please note that Nexxtech is privately owned brand belonging to The Source, a Canadian electronics retailer. Nexxtech products can only be ordered from The Source in Canada. The specifications, brand name and model number are provided for reference for voltage and amperage that appear to minimise the occurrence of the battery drain bug.

Same here + instant charge

I just entered my office and noticed the phone was off. I turned it on again and the battery was at 1%. I needed the phone so I connected it to my netbook and it was charging slowly. After it was at 3% I got me an coffee and when I looked at the phone it was already fully charged??

Now the drain is normal again. Running CM11.

Yesterday I fully restored CM11 using CWM because I was running an custom (pinky) kernel which wasn't stable for me. Seems to me it's an software bug/calibration thing.

When it was at 100% I used the battery calibration app, hopefully this solves it.
[Moto G Q&A, Help & Troubleshooting] flashsam:
I had this problem a few weeks ago that when I unplugged the phone from the charger (wall not computer) it turned itself off and when I turned it back on it said 1%. After plugging it back in for a few minutes it went back to 100% and was fine after that.

Since then it's all been fine with no problems.

Then half an hour ago my phone was on 74% (and NOT plugged in) and it suddenly made a beep noise and turned off. When I turned it back on it said 1% so I plugged it back in expecting it to jump back to 100% but it never did.

Been charging now since it happened and it's now on 23% so this time it really does appear that the battery really did manage to lose all it's charge!

Time to get a replacement?
[Moto G Q&A, Help & Troubleshooting] lost101:
If I were you I'd consider replacing the wall charger first. I've never had the issue with my HTC one; I believe a good wall charger will keep you out of trouble until Motorola figure out a patch.
[Moto G Q&A, Help & Troubleshooting] flashsam:
But it hadn't been plugged in for 11 hours when it happened. Are you saying that using a bad charger can cause this to happen hours after being unplugged?

(if so, maybe they should actually sell the phone with a charger instead of just a lead! Although I'm using the same charger I've used for years with all my phones with no problems)
[Moto G Q&A, Help & Troubleshooting] lost101:
Sorry, I didn't read your post properly. I just believe the same thing will eventually happen with a replacement, OTOH returning it might motivate Motorola to take the issue seriously.

Same battery drop problem here

Hey everybody. Same problem here. I waited the phone for a month, I have it for three days now and the battery drop problem occured yesterday two times in a day.

Once when I connected the USB cable from the PC. The battery dropped from 90% to 1%. When I put it to charge in 2 minutes it was back to 90%.

Second time, I just left it on the table and when I picked it up it was off. Turned it on -> 1% battery. Back to charge -> in 2 minutes back to 100%.

So I took the (hard) decision to return it, I just loved this phone, for having another 200 euros phone before, this one was 10 times better in all ways.

I'll try to contact Motorola though.
[Moto G Q&A, Help & Troubleshooting] rogeriorp:
Does anyone else on stock KK can't get their device to 100% charged - full status? Even on DU Battery app, it doesn't load the slow charge, which it did on 4.3. After 8 minutes out of the charger, battery went from 100 to 98% only at wifi and low screen settings, worth mentioning that on 4.3 I could keep 100% charge for some time - due to its true 100%. Running on ART, stock kernels and unrooted.

Solutions or suggestions? I'm about to factory reset it if nothing else works.

Issue happens with white OEM Motorola USB cable.
[Moto G Q&A, Help & Troubleshooting] nelusan:
This may be true. For me it was with another cable. And once without any cable connected. And I don't think it's an application causing the issue because I had the same applications on my old phone. And I was using the same cables before. So either it's hardware, either it's in the ROM distribution. As others said, I don't know if I want to wait and find out or just return the thing.

I only meant using the white OEM Motorola USB cable will not stop it happening. It can occur at any time, under any conditions.

Tracked mine down to a dodgy usb desktop stand - it would act dodgy when connected to that, battery to 1%, sometimes rebooting on connect.

So change your cable, or change your charger... therein lies the issue.

This problem has nothing to do with cables. Its a bug. You can download apps that show you how much battery you really have. I have had this bug hit me twice in the last 24 hours alone.

[Moto G Q&A, Help & Troubleshooting] vanderjr5:
But if you turn it back on it will be 1% for like forever, until you either recharge it or run it dry, you can guess how much by the battery voltage I think, mine is 4300mV full and 3200mV empty I measured

I don't think the battery is actuially discharging. It's the battery stats that are getting goosed, and the phone shuts down.

I get the same thing in CWM.

Same if I get the fuill drop to 1% problem, ten to fifteen munites, and it's back to 100% - iot can;t posisbly have charged 1 to 100 in 15 minutes, so it must be the phone thinking there's no charge when there really is.
