[Q] Charging issue that defies common sense...

I searched here and google and found various charging issues but none quite like what I am seeing. The night before last, I plugged my A100 in before bed like I normally do and saw the power light turn orange. In the morning, I unplugged it without even looking at the LED because I just expected it to have charged completely. When I got to my car and turned it on, it was at 32%. I thought maybe I had something running that was eating battery or I didn't plug it in all the way overnight so it didn't charge. I plugged it into the car charger and went to work. When I got to work it was still at 32% but I didn't use it the whole time so I thought that was odd. I pretty much didn't use it the whole day since I knew it was low on power and I didn't have a charger at work. I got home and saw that it was at 28% so I plugged it in. About an hour later, I checked and it was still at 28%. Thinking that was odd, I turned it off and left it charging with it off for an hour. Turned it back on an hour later and still at 28%. I spent a little time using it while plugged in trying to kill off apps and things but it drained to 18% even though it was plugged in, the power LED showed orange, and the battery icon on screen showed charging (lighting bolt). At this point I started to worry that something was seriously wrong. I turned it *off* and left it plugged in all night after checking to make sure the LED was orange. In the morning, the LED had turned off completely (not blue or orange). I turned it on and saw that it was still at 18% even after charging all night turned off. I unplugged and replugged and the LED came on orange again.
So here is where it gets really strange.. I decide to go through RMA process since I'm still under warranty. I don't want my private data on it when sending it to them so I do a wipe. On a whim, I plug it back in after the wipe and guess what? It's charging! What the heck?!?! I had thought maybe I installed something that was causing problems but since it wasn't charging even when turned off, I figured it couldn't be an app. Can an application cause the device not to charge even in the off state? I thought maybe my battery stats had gotten corrupted so the percentage readout wasn't accurate but right after wiping the data, the battery was reading 18% just as before the wipe.
Any thoughts? Anyone ever see anything similar? My gut says to RMA it still.

Reboot the device.
It's a bug that happened to me on Honeycomb all the time with A100. (No longer happens on ICS)

Did you actually read the OP?

Yes, multiple reboots didn't help. No charging even when off. Started charging after wipe. Very odd.
So, after my wipe, I set out to see if I could get it to fail again. I loaded a couple of apps that I had loaded a couple of days before this happened and it stopped charging again. Unloaded each of those apps and still no charging. Did another wipe and still no charging. Conclusion is it's busted and just randomly charges on occasion. Sending it in for RMA today. Still very odd that it was reliably charging after that first wipe.

I myself am experiencing exactally the same problem. Any fix found?

Similar thing happened to me. The only thing is I didn't realize it wasn't charging until it was too late and the battery was at 5%. After it shut off, the only way i could get it to turn on was by holding down the power button and plugging in the charger. It didn't get to try a data wipe (didn't have enough time lol). I sent it back and they replaced the system board. Said it was not recognizing the battery properly.

I own two tabs, and one had this issue, the fix is actually quite simple. Let the tab die. No battery life at all. Then, when your sure its dead, plug it back in, and let it charge to full. I haven't had the issue on the tab since.

my charge is on 3% too, but no good luck for me. seems a most serius problem
thanks.

any news guys? I bought a old ACER A100 and only power on while it plug in, so I went ahead and changed the battary, it still does not get charge.

Is the happening on complete stock? Or a custom ROM, if so, which one.
Also, reflash said ROM if applicable, and make sure the data is wiped.
I like the drain the battery idea, although its risky, these tabs can brick if it gets below 10%, current/voltage act weird when its low and blow a breaker inside and keep it from turning on.

What percent does it show the battery at while it's on?

My tab has the charging issue, but it is self inflicted. It was dropped, which cracked the lcd screen. I ordered one after a week or so and replaced it. At this point is when the charging issue cropped up. It powers on only if plugged in, and will get to 3% charge no matter how long it is plugged in. It will also only show the 3% if the charger is unplugged. It will then run for a few minutes until the battery dies. Also, the orange charge blinks about one minute after the charger is plugged in.
I found a reference on the web that if the battery charge gets too low the A100 can't charge it. I also found references that people had this problem, and Acer replaced the mb. I took a shot on the battery since it was a lot cheaper. Still the same. That doesn't the battery was not the issue since it was an ebay battery. So for now I just use it in the living room, plugged into outlet. Works good for that.

Ha! Found my own post by doing google query. Wow, didn't know this thread was still somewhat alive. So, I sent mine back as I mentioned in my last post back in February and they took a week and sent it back to me completely untouched. Basically said it was fixed but the same problem existed. I sent it in after a wipe but I did configure my wifi access point before I sent. When I got it back, my access point connected immediately and it still would not charge. I called them right back furious and demanded they provide shipping back to them because they clearly did nothing. They finally agreed and I shipped it back. After another two weeks of transit and repair time, I got my tablet back and this time it appeared to be fixed.
So, flash forward to 3 weeks ago. One morning I woke up and the tablet wouldn't power on. Black screen but the home "button" would light up when touched and power button would light up when plugged in and such. After several attempts to reset by holding down power button and using the recessed reset button, it was still not responsive. Tried up volume (and down volume) while powering pressing power button.. tried holding down reset button while pressing power button.. all with no result. Submitted rma request and was immediately granted without review. Sent it in and after about two weeks, got it back and it appeared to be working fine. Just this past weekend (about a week after I got the tablet back), I noticed that it was 3% after sitting on the charger for 2 days straight over thanksgiving. ARG!! Looks like another round of RMA here. I have not tried wiping but last time the charging issue happened, it was intermittent for about 2-3 weeks getting worse and worse before finally never charging. I am now near the end of my warranty period and I worry that if I send it back now, they will just turn it around and say it started charging after a wipe. What a piece of ... this is? This will be the 4th times in one year of ownership. I've almost spent the difference in cost between this tablet and other more expensive options in time and shipping alone.
I will try wiping it and then running it all the way down. Although I almost want it to fail hard right now so I can get it RMA'd before my warranty is up.

Battery Failed

Hi Guys,
Ive had my GPAD for about 2 months now, i came to use it today and the device was dead. Simple enough i thought the battery had just drained, however when i plugged it in to charge it just did a strange bootloop. The LG screen appeared a battery icon with 0% appeared and then instantly rebooted itself doing the same process over and over.
I thought if i left it for a bit it might need a charge before going any further i.e. battery was completely drained. I have left it for over and hour and its still doing the same thing. As soon as you unplug it from the mains it dies and wont turn on.
I'm assuming my battery has completely failed, has anyone else experienced this with this device. I've owned lots of phones and tablets over the years and have never known a battery fail like this before?
Thanks
Cookie

If it immediately gave a sign of life when you plugged it in, then it was not off. Power it off with the power button, then plug it in to charge. Try this also on your computer if that fails, and finally, treat it as if it were bricked and thus set it to Download mode, and try a recovery.

I just had the exact same problem myself.
I did use CM11. What did you use?
After going back to stock it worked fine. Now, I am just about to try cm11 again.

Sorry for Kate reply, didn't really Jeep an eye on the thread as I thought it was just dead lol. I used madhi ROM which I think is cm11 based. I'll try and put it back to stock.
Thanks for your reply

Nexus 5X won't turn on, bootloop when charging

So yesterday I was trying to make a phone call and the phone went dead. I tried turning it back on but to no avail. When connected to a charger, it just shows the battery for a while and then it disappears and reboots to showing it again only to reboot itself again. Needless to say, I am stuck with a bricked phone. I managed to get it up and running by flashing the stock rom but after update to Android 7.0 the problem came back after like 10 hours. Now I can't even get into bootloader without the phone being connected to a charger, which is a problem because I can't flash anything through charger obviously. Connecting the phone through USB does not work, the phone stays dead like it is out of juice. With that being said I think it might be a faulty bootloader. The power button is fine, so I think we can count this option out. Any other ideas? I am considering taking the phone to the shop where I bought it as it is still under warranty but because it is not Google they might refuse to replace it with a new one or repair it. Is there anything I can do?
EDIT: I sent it to LG.

I had the same issue just a few weeks ago, did you ever get it back? How long did it take? Was covered under warranty?

G7 will only charge when powered off

I seem to be having the same issue as found on this thread, can't find anything here though.

Anyone else have the same issue and found a fix? Guessing this might have to go back to lg.
Thanks!

I started getting this issue yesterday a day after I got a software monthly update for Nov. I normally shut the phone off to charge but sometimes leave it on. When plugged into something it doesnt seem to detect its plugged in. I even swapped cables to a slower charger and same thing. It doesnt see it.
When I fully charged it off, It beeps the battery and does a circle hue randomly by the home button but than detected the connection to pc. I ignored it and started up again but without the beeping, just wont charge when on. There is no dirt or anything in the unit,. I have not moved any-wires, they have been sitting in the same spot on the counter since day 1. I'm gonna try a factor reset if it keeps happening a day or 2 from now.

Same problem here, it was behaving strangely few days ago (charging problem right away but worked in the end so let it go) and now it charges only when off or if plugged within 30 seconds after turning on and only on normal charge speed (not quick charge). Tried to wipe apps and everything, did the facrory reset 2 times but still nothing.

I have similar issues with charging my g7, first give me notification of moisture detected on USB port, then can't charge normally need to plug a few times and sometimes get slow charging, i was thinking have faulty USB port, and have poor battery life.
Then I turn off and put the cable and charges normally and realized that it's software issue.
I flash the ULM10i firmware and now everything work flawless the USB port charges when it's turn on and have very good battery life now.

As an update, I called LG and they basically stated that it sounds like a software issue and to send the phone in. I declined hoping to get another update that would fix it.
I have yet to get one from T-mobile. Long story short, it corrected itself and now charges off or on and no longer does the beeping. Whatever it was, was a bug that temporary for me.

same problem here; no moisture errors, aleatory starts charging when it's on, poor battery life; mainly starts charging with the phone off

problem solved! I've forced LG BRIDGE to reflash the ROM and voilà, all working like a charm. Just download from lge.com, install LG BRIDGE, under "software update" ... "update error recovery" and it will download and reflash the working ROM.

Z5 Premium won't turn on

Z5 Premium not turning on
hello everyone,
PLEASE HELP ME!
My z5 premium was working fine.. battery was charged too, and suddenly it turned off, and it didn't turn on back again. I've tried all the different ways and solutions that should turn it back on:
hard reset didn't work
2 minutes hard reset didn't work
hard reset button didn't work
plugged it in using it's OEM charger and usb cable didn't work either and LED didn't lit up
plugged it in to the computer nothing happened, wasn't detected with no sign of life
I had to take off it's battery cover (using professional tools) unplugged the battery, connected the phone to the charger while the battery is unplugged, and nothing happened reconnected the battery back, and plugged the phone again to it's wall charger, and no sign of life.
i left it there all night long since the afternoon. and when i came back in the next morning to check if the phone is charging and the LED is lit up, but again NO SIGN OF LIFE!
(BTW, the phone is in mint condition and it was never been disassembled or repaired)
Please if anyone have an idea what this could be?
if anyone has encountered the same problem and went through the same of what I've been, and was able to repair it or find a solution PLEASE LET ME KNOW!
Now, I'm thinking of 2 things: either the battery is completely dead(damaged) or it's the mainboard which I don't hope to be.
PLEASE LET ME KNOW YOUR THOUGHTS ABOUT THIS!
Now, forget about any sort of software repair, as I explained above, the phone didn't succeed in that.
So, any help or suggestion would be so much appreciated.
Thank you all for taking time in reading and participating in this topic.
Have a good day.

Not happy reading this thread. Why so many issues with Sony Android... Anyway;;
- I recently had the same issue - or an issue in the same ball park. Phone Just died and refused to charge, but would show a red LED and try to boot when plugged in.
- Sent it to Sony, Hoping it is only a dead battery
The OP sounds like a they have a USB port issue or a board issue, also OP phone will no longer waterproof after removal of cover.
Unclear as to whether you have tried the following;
- Turn on whist holding camera button instead of Volume up/down. it is worth a try
- Try to grab an official sony charging cable- basically impossible to buy nowadays, maybe a PS4 controller cable? try it

My stock unrooted Z5p died like this in April. Have the same issue as the OP and tried all the same solutions. My Z5p had only been used indoors for months with WiFi before sudden death. Replacing the charging port did nothing. Using the OEM cable and charger with a new battery gets a 2 sec red light when connected to power and starts booting up until the swirls (gets past Sony Xperia and powered by android screens). Then the screen goes dark and shows the big battery for a couple of seconds.
I didn't realize there was a sudden death problem with Sony phones until I started trying to fix this. What's even crazier is that I had (have) the Xperia Z, Z Ultra, and the Z2. The Z2 was used in the rain constantly and even survived an ejection from a handlebar mount at 15mph onto asphalt. (All these phones were rooted and using custom ROMs/kernels.) Seems like Sony has a serious QC issue they're not taking about.
