Battery or Mobo, opinion please!! - G2 Q&A, Help & Troubleshooting

Replaced the LCD full screen assembly on my LG G2, all went smooth following a YT video couldn't really have gone wrong,
Switched phone on and battery displayed 0% for several minutes, eventually getting to 2% when I turned it on, all was still OK, however it dropped to 0% within a few minutes even while still plugged in,
Then it was completely dead, no charge light and couldn't turn on,
Removed all of the components again from inside of phone and rechecked all of the connections, again all OK, this time it cam on again!! 0% charging, so I left it charging waiting as long as poss, 45% it was at when I checked but left it while I was sleeping,
Woke up this morning to phone completely dead, cant power on and no charge light showing
Am I wasting my time buying a new battery? could this be another component? LCD?
Appreciate any help,
Thanks

have now disassembled and re-assembled a further twice and now it does not power on at all
no red flashing light and nothing on display

I've got a similar problem. Did you find out anything? Bought a replacement screen from ebay, and was really confident I could do this, since I earlier replaced the usb charging port with no issues. Of course the battery was discharged completely before this, but I charged the phone and it worked a week ago (which resulted in an annoying alarm that I was unable to shut off because of the broken screen). So after replacing the screen, I plugged it in and turned it on before putting on the back cover. At first it vibrated and I could see the backlight turning on. Then I could see the red led, and thought it was charging, but then the led started to cycle between different colors. I was not able to get a picture on the screen. I then plugged it out and put on the back cover, in case that was needed (didn't seem so from the yt video I used). After that, nothing. Not even a LED. And the phone didn't get any hot like it does when charging/working. It did somewhat get a bit hot the first time.
My first suspect was the battery. It did take some wiggling and force/heat to remove it‚ and it did kind of bend at the edges, but not very much. Any ideas?

[Q] HD Dead?

Hi
I'm not sure if my phone is dead or the battery is dead. My HD2 got slightly wet - and I mean slightly. The phone continued to work. I dried it out over night and re-connected the battery. The phone booted up ok and was fine. I went to charge it and everything was fine, however when I returned to the phone it now won't turn on.
When it is connected to the usb or charger I get no lights. So my question is this: Is it possible to power the phone without the battery installed? If it is then it looks like my phone is dead. If it isn't then is it likely that the battery is dead and the phone might be ok?
Is there any way to test?
Thanks
Jonathan
if the battery becomes completely flat it can become unresponsive to charging, and when you plug your phone in it tries to turn on, thus keeping it flat.
you can try....with battery out, connect charger. nothing will happen, but now when you put the battery in it won't try turn on. leave it to charge for an hour or so and see if the charging light comes on.
but more importantly, you have gotta make sure the phone is dry, battery too,,, jar/bowl of rice and somewhere warm seems to be the usual advice.
Thanks for the suggestion. I tried what you said but the charge light hasn't come on. I did get a short vibration out of it when I first put the battery back in so I hope that the battery is just dead.
this is going to sound crazy on many levels, but this happened to me when I dropped my phone in a bathtub. What you want to do is put it in a container of rice. Trust me. Leave it for 24 hours or longer if you can, after this it could be working, if not it's probably fried.

[Q] battery problem, red led light is blinking, bought new battery, no bettering

Hi guys!
I know, that there are some threads about the topic, but i think, here it is a bit different...i´ll describe:
Everything was OK with my withe G1, since I forgot to recharge the battery, and the G1 switched off. I wanted to recharge it, but - you know- the red led light blinked...i read different threads etc, and then I decided, to buy a new battery. The new battery arrived yesterday, and I put it in my G1, tried to switch it on, and it worked. I was quite happy! I taped it on the charging unit, and the first problem: the battery display didnt moved, it remained at 23%, also after a few hours at the charging unit. I knew the problem, because it was the same with my old battery, but it doesnt interest me, because the battery recharged, only the battery indicator showed that not. I thought OK, dont thinked about it, and waited. Today: I took my G1, yes, battery display at 23%, no problem. I switched it off and after a few hours I wanted to switch it on. Second problem - F**K! The red led light blinked...and now, the battery doesnt recharge at all. The G1 works now only, if the charging unit is put on it, if I remove it, the G1 switchs off. Its the same behavior with the old battery.
I dont know what to do now, because i dont think, that it is a hardwarebug, because yesterday it worked, with the brandnew battery. Or is it possible, that the G1 destroys my batterys while switching it off?
I hope, that there are solutions for this...because im loosing my temper slowly...
Can you charge the battery if the phone is off? Red led light should show. You should wait even 30-60 minutes for this - it depends of battery discharge. If the red light will not show this will means that your hardware is broken (phone or phone charger). You can try use another phone charger to test.
That works sometimes....at the moment not, but one hour before, yes.
I had the G1 with the USB cable on the PC, the phone was off, the light was red (not blinking). I waited about 50minutes, then disconnected, tried to switch it on - nothing except a red led light - blinking
At the moment, there isnt any led light, if i connect the phone to the charger unit or the PC...
It looks like hardware problem :/
Would be OK, because there is still warranty.
But what irritates me, is, that it worked without problems, when the battery was charged. Also with the new battery...worked good, since I switched the phone off.
I only want to be sure, because the return merchandise authorization (rma) takes quite long time...
I have the same problem. last week i bought the phone, and used it till the phone battery was empty. I tried to recharge the phone, but i wouldn't go on, only the red light blinking. I had the phone charged for 2 days, with the og charger, no result. Looked like the phone was dead.
Today i tried it again, still no result. All of a sudden the phone turned on and was charging. It is now on 99%.
Should i contact HTC?
edit:
sorry, wrong forum
Just a wild guess. It could also be the ROM that you have. I had a similar problem with my battery drained out like that with flashing red light. Come to find out later that it was something to do with the ROM (CM6.x) that I was using.

[Q] Mytouch 4g died in sleep?

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.

Tablet won't turn on

Hello,
I bought this tablet years ago and noticed back then that the battery was dying quicker and quicker. I gave it to my mum for her hospital stays but she doesn't use it anymore. The tablet doesn't seem to charge. When I first plugged it in, the screen briefly flashed once and then nothing.
I have taken the battery out and plugged the cable back in and the screen lights up, like a backlight or something, but still blank.
Putting the battery back in stops this. Do I just need to replace the battery?
Thank you.

BATTERY (?) Help

Hi Guys, so I flashed Resurrection Remix and it was working fine. Few days later, I woke up to my phone continuously vibrating. Upon checking I saw that it was vibrating because it was doing a boot loop. Unfortunately my PC was broken at the time too, tough week.
Anyway, I let it do it's thing until it runs out of power. It never did. Seriously I waited for a day. When I slept, it had 20% battery (not charging). So I thought maybe, the power button is acting up again which has happened many many times before.
So I opened up my phone and adjusted the power button. Even, holding the volume up while plugging in didnt work anymore.
While I was there I saw the battery connector thingy, I unplugged it and re plugged it real quick without breaking anything. And It restarted and the device worked fine.
But.... The battery icon is steadily at 50% for a min then drops to 0% even while connected to charger. So, I charged it for a few minutes but it doesn't move.
I was about to do a factory reset but it shut down. The battery icon doesn't appear, only the red blinking led light. I tried charging it like that overnight to no avail.
I then tried to remove the battery connector again and as soon as I plug it, the screen turns on then off again. Sometimes it gets to the battery charging icon before it shuts down. If I bend the connector downwards it sometimes turns the screen on and sometimes doesnt.
I took it to repair shops and they said that the problem is the battery and ofc to no suprise, they dont have a replacement.
Do you guys have any idea what happened? Was it a button issue, software issue or indeed battery issue. Before all this happened, the device was working perfectly.
Please help. I miss my phone already.
I think it due socket of battery, can you open the back cover and plugout and plugin this socket, will be OK
