Phone issues charging and powering on - myTouch 4G Q&A, Help & Troubleshooting

Ok so, last night my phone was dying. I didn't charge it until about 5 PM today. However when I plugged it in, it wasn't picking up charge. I took off the battery and it looked like there was water under it, not a lot (no I haven't gotten my phone wet... or near water at all) so I wiped it off and plugged in a spare battery that I have. When I plugged that in, the camera flash turned on briefly and the phone began to blink orange. I left it plugged in for about 20 minutes then I tried turning it back on and nothing. Now when I unplugged it again I tried doing other thigns like turning it on without a battery while it's plugged in, doing it through usb (which when I plug it in through usb the PC makes that USB sound) and for a brief second I tried turning it on, and it DID show the "MyTouch 4G" logo, then it shut off. It hasn't been picking up charge right and I can't get it to turn on... What can I do? I got this off of craiglist and it was working fine for almost a month, so there's no warranty. Any suggestions?

Also, whenever I put in the "good" battery, the phone vibrates and the flash turns on. What do you guys think could be done??
And when I plug it in through USB it looks like it's "charging" (as in the light at the top is orange) and the buttosn turn on if I mess with them, but no image on the screen. Frustrating.

[Q] Aria not charging

I've had my Aria for about a month now, and just last night I started running in to trouble getting it to charge. I had plugged my phone into an outlet when I went to bed (I saw the orange light go on, then turned the screen off) and when I checked my phone the next morning, the charging LED wasn't on and the battery was at 42% (a fan was plugged in, too, and it was clearly working, so it's not the outlet).
Now, no matter if I plug it in to the wall or my computer, the charging LED SOMETIMES goes on for a second or two, but then as soon as I turn the screen off the LED goes off. Also, if I get it to start charging while using the phone, I noticed that putting the phone face-down makes it stop charging. I can't connect it to my computer to sync or anything, and Windows sits there and makes the "device connected" and "device disconnected" sounds in rapid succession.
Does this sound like a problem with my Aria's software, hardware, or the charger itself?
One thing you can do is take it to where you bought it and have them open a new box or use a known good charger and usb cord to test those two parts out. If that does not fix it then you are right there to take a new phone home.
So I forgot about the #1 rule when it comes to dealing with fussy electronics: Wait a day. Nothing changed, physically or software-wise, but my phone will now charge just like it used to.
Of course, thinks makes me suspect that something was freaking out on the software side, but hopefully it won't happen again once I put CM6 on it.

Won't Boot

So my phone died earlier today and I left my charger in my friend's car. When I got it back, I tried to plug it in and turn it on, but nothing happened. I know sometimes you have to wait until it has a certain % charge before you can turn it on. I made and hour trip back home and when I got back I still couldn't get my phone to turn on.
When it's not plugged in nothing happens at all. When it is plugged it it repeats the boot logo thing over and over and over and eventually goes black. I can't get to any kind of menu. I've tried the X+Power option. Nothing.
Any help?

You might try and swap batteries with someone with a D2 or D1 to see if your battery is messed up other than that I'm not sure what to do because it sounds like you don't have enough power but if it's not charging you could have a software issue, because the D2 won't charge without software.
Does your white charging light on the side turn on when it's plugged in?
Are you running a Custom ROM?

[Q] HD2 dead Battery?

I woke up this morning and my phone was off. As you probably already know, the HD2 does not stay off if it is plugged in (with WP7 on it). I checked the charger and outlet; everything was plugged in. I also used a different charger, and different outlet which I know works, and got the same result. When the phone was plugged in it would turn on and start booting then I would see the flashing light - indicating that the battery was dying- and the phone would shut off. This happened like ten times.
I took out the battery and put it back in, with no results. Then I switched batteries and it finally worked. I'm still learning about technology in general; is it possible that my other battery is dead?
Has anyone else had this issue?
your other battery is probably just flat, and cant charge because it needs a running OS, and since the OS cant get far enough into the boot sequence to start charging, the several times it bootlooped will have drained the last of the charge.
Options - external charger, loan of a hd2 running winmo, or my personal fave, (used it three times now) usb cable with end cut off, red wire to + black wire to - on battery, hold for a minute or two, should have enough juice to boot far enough to begin charging. Best to use wall charger rather than pc usb, since the pc may connect and disconnect time or two whilst booting, preventing continual charge.
I forgot to mention that the first time that the I booted with the battery that doesn't seem to work I actually got to the wp7 home screen and it was about 20 seconds before the phone died.
Even so, I'll try that cut off cord thing when I reach home. Thanks for the advice.
I guess my phone just felt like being retarded the "flat" battery is working now.

[Q] Phone suddenly went dead (latest MIUI 2.6.35 kernel)

My phone just went dead yesterday, while playing tiny tower. Suddenly turned off, and would not turn back on. When I connect the charger, the led in in the speaker blinks. When the charger is not connected, the phone is completely dead. And it does not respond to anything either way. I don't know if this is rom related. Probably not? I'm thinking returning it to the shop, and hoping for the best is my only option, unless someone here has a better idea.
Update: I tried turning it on, connected to the charger, but without the battery in. It starts. So I guess the battery died? Suddenly and completely?
What happens if you turn it on without battery in and then insert battery?
Mine did a similar odd thing when I first wiped battery stats. Was playing angry birds to drain battery right down and it turned off, but would not start. LED just blinked when power was in. I just had to plug it in and unplug it a bunch of times and it finally started charging.
I did wipe battery stats last week, but have been through a few drain/recharge cycles since then. When I start with the charger connected and insert battery it gets past the boot animation and then shuts off. I tried with a different battery yesterday, and it worked fine. When you say plug it in and unplug, do you mean connecting and disconnecting charger, just repeatedly?
yeah, was just plugging and unplugging a lot and it finally worked. If another battery worked then that would seem to be the fix.
Will try that. Thanks!
Managed to get it to start by putting the battery in after starting with just the charger first. Had to try a bunch of times before it worked. Been charging now for 5 hours, but it never gets past 10% charge on the battery? Do I just let it keep charging or is there some other way to fix it?
That happened to me in the day I bought my phone. It only started with the charger plugged in (and with no battery).
I thought the problem was in the battery, but in the store they tried with a new battery and the phone did not connect. So they replaced and everything is fine (since September).

[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.
