Hi,
Bought this back and the end of January, and it's been in use ever since. It was charged about three weeks ago and then I got busy, so it discharged. When I plug it in, absolutely nothing happens. It shows no indication that it is charging at all. I left it plugged in overnight, and it does not appear to have charged at all. I tried a couple of cords. My wife's N7 is fine, so I used her cord, with the same result.
This is a completely stock, unrooted N7. Can anyone think of anything else that I can try? Or is this thing just dead?

i was working today and the phone died on me. Havent charged it in days. I came home, tried to turn it on real quick, and it turned on and then off before it booted up, then i was like ah hell ill plug it in. plugged it in it started to boot so i went to wash my car. hour and a half later i came back to grab my phone and its dead. no light, no anything, just dead, unplug it, tried to start it. dead. nothing, no light. I thought ok, cable broke. so its plugged into my laptop via usb and still dead. any ideas? its flashed with wm6 im leaving the country monday and i need this working!!!
I've had this problem before. I just left it plugged in and eventually (after a few hours) it started charging.
Are you using the original MDA charger? I had a similar problem when using a motorola charger...
So, this phone was working without any problems but then my wife turned it off and left it in the drawer for about 3 weeks when she went overseas. When she got back and tried to turn it on it wont turn on. We figured it might have drained the battery so we plugged it in but now its not charging either! When I unplugged and plugged in, the LED blinked orange once but now it wont even do that either, no power, no LED, not charging either. I have tired everything, left it disconnected, battery out for an hour, then put it together and tried to charge, still nothing.
Any ideas? It is already out of warranty so talking to T-Mobile is out of question.
Nothing has been done to it, it is physically fine, it was just off for a long period and not it just wont respond.
Edit: Fixed it! I don't know what, I was almost giving up, but I took the battery out and blew hard on the battery contacts in the phone and in the charging port then plugged everything in and put it back on charger, orange light started to blink and then went solid and now its charging. I just turned it on. This phone is dodgy, no other phone hard bricks like this if you leave it off.
Some phones don't function with completely discharged battery. Actually, most of newer phones. You need to leave the battery inside and the phone connected to charger for some time, till the charging light shows up. MT4G is very far from being "dodgy", doesn't differ from many other phones that behave the same, and you were nowhere near "hard brick".
Good luck in powering up Motorola Defy with completely discharged battery.
Recoverable problem

Had a similar problem. Phone died while using it then wouldn't light up when plugged in. Left it plugged in for half an hour wouldn't seem to charge via wall or car charger. Tried doing a hard reset with/without the battery & plugged in/not plugged in in various combinations. Got nuthin. Drove around for hours looking for a replacement or open T-Mobile place, until it got too late and I went home. Live chat with T-mobile rep was a waste of time. Plugged it in the wall and left it, as this once brought back a G2 battery that I thought was cold dead. Five hours later it was lit up and charging, showing 40% charge on the battery indicator app once I turned it back on. "HTC Sense" crashed immediately on boot then recovered. Seems to be fine so far.
- Suggestion; plug it in and leave it overnight if it seems cold dead and doesn't appear to be charging. It seems to need to hit some critical threshold before it will work again (as indicated by previous poster). Also pick up a couple spares off amazon or newegg if you don't have a second phone available.
Hello all,
I have a Galaxy S4 (i337) since April 27, 2013; it's been working great...until today. Earlier this afternoon I plugged my phone on the charger because the battery was running low. I noticed that the phone wasn't charging at all...or at least it seemed that way. On the battery section of the Settings app, it stated that the phone wasn't charging, but the percentage kept rising every few minutes. It did the same turned off, on or on TWRP, but the phone kept saying it wasn't plugged in.
Hoping it was a kernel/driver issue with the nightlies I've been running I switched ROMs and even restore from a backup I made a few days ago. Nothing new happened. I kept getting the "not charging" thing. So I unplugged it and the battery started draining quickly, about 10% every 15-20 minutes on standby and light use. So I switched batteries, chargers and nothing.
So, can anyone tell me what's going on here? I already purchased the USB board, but I was wondering if there was an easier solution. I tried cleaning the contacts, but they're not as bad as they could be. So if anyone can shed some light on this issue I'll be very grateful.
Thanks!
Update: This keeps getting weirder. I turned the phone off and plugged it in overnight and this morning the phone fully charged. Although when turned on there's no indication whatsoever of the charger being plugged in. This is frustrating.
So about a month ago I rooted my d800 and put CloudyStock on it. Everything was fine until a couple hours ago when I notice the LG symbol on the screen like it's restarting. I figured I had just held down power button or something but got distracted and wasn't too worried about it. Phone was probably 70% charged. An hour or so later I go to turn it on and it's totally dead. I charge it and it doesn't react to the charger at all, no lights, no charging indicator, nothing. I tried a different charger.. same thing. It's just totally bricked out of absolutely nowhere. I haven't been messing with it or anything at all since back a month ago. When the LG symbol came on I was just carrying from one room into another and hadn't been doing anything on it. I tried plugging into my computer to try some recovery magic and my computer doesn't even recognize anything is connected.
So, assuming it doesn't magically come to life in the morning, I'm guessing my only option is to pay the deductible and get it replaced. I'm just kinda confused why/how this would happen totally spontaneously. Has anyone heard of any history of something like this? Thanks!
I'm so bricked. I'll try to be brief.
I successfully rooted a 2 month old sm-t713 a few weeks ago. I was out flying my drone with the tablet attached to the remote control. The tablet was discharging battery life to the remote. I placed the tablet down for a minute to check on the drone that just landed and when I checked the tablet...well it was off. I tried power on immediately...I then tried hard reset. Nothing.
At home I tried multiple reset attempts and nothing. Also the tablet refused to charge when plugged in. I finally opened the back cover and disconnected the battery. I left it for an hour and then tried again.
Now it gets weird.
The tablet turned on and started to load the os... nougat. It got about 2 mins into the Android loading screen and then died.
I retried turning it on. Nothing happened. I plugged it in overnight and still nothing. I tried unplugging the battery again from the motherboard of the tablet for a few mins. When I retried powering it on again I got a 5 second glimpse of the Samsung tablet logo screen and dead again.
Now it's really really dead. I tried multiple attempts at reset and download mode and no life. The unplugging battery trick does not work anymore.
In desperation I bought a new battery and plugged it in but the tablet did NOT respond to that either.
So now I'm at a total loss. It's only a few months old and doubt Samsung will fix it under warranty.
Does anyone have any ideas as to what happened? And any way to fix it myself?
Help really appreciated. Thanks. I feel like a dolt.

It's obvious, but have you tried different chargers and cables?
When you put the new battery in was there any life at all?
The only reason I think the battery trick worked is because unplugging it allowed it to re-energize somewhat so it could power on when reconnected.
Now it's completely drained there's no power at all in it.
Same goes for plugging into the mains, no power getting to the board.
I suspect a possible faulty USB port.
Thank you for responding.
I did try the oem charger, my car charger, a 3d party wall charger and a 20000 mAh portable charger. Also multiple cables. I think the charging port is working because the portable charger flashes when actually charging a battery. It does not flash at all if plugged into a full battery. Somehow the tablet is being blocked from turning on.
Plus just today I did use a fully charged replacement battery to test the tablet though...my coworker has the same tablet and allowed me to remove his functioning one today...and that failed when i connected it to the Samsung. I even connected the battery from faulty Samsung to his tablet and his turned on immediately.
Argh.
try a "Samsung Jig" you can get them off ebay for about a quid!
