[Q] Motorola Backflip Overheating/Won't turn on.

So, here's the deal. I have a Motorola Backflip, it has been rooted and now runs 2.1 instead of Android 1.5. A few weeks ago, I woke up after charging my phone all night and it was very hot. It wouldn't turn on, I panicked, then later I tried and it was fine. Now, it happened again this morning when I woke up. It was very hot, I waited for it to cool off, and tried to charge it again, because it wasn't charging all night. When I plug it in, it recognizes it's plugged in with a little vibration, does the white screen with the Motorola M for a bit, then shows the "0%" screen with a charging battery. Then, it vibrates to show it's plugged in, shows the white screen with the Motorola M for a bit, then once again shows the "0%" screen with a charging battery. It keeps doing that, and won't charge. I obviously can't turn the phone on since it will not charge, and the battery is dead. I am using a normal wall charger, but I will try charging it through the computer to see if that makes any difference. Any suggestions? Is my phone okay, or should I give up?

U need a new battery

Just woke up to the very same thing with my backflip. It may have something to do with the amount of current going through the connection. I had mine plugged into the back accessory port on my old Blackberry Bold dock. The one that has a spot for the bold upfront, spot for a bluetooth headset, extra battery charger and an extra USB port on the back(I use it and my old Bold as a bedside alarmclock/internet radio now .) I had been playing a bit of leaf green on gameboid last night with it plugged in and woke up to a feircly hot Backflip that would not power on. it was on until I picked it up then turned off. i hit the power button and it just kept cycling through the moto M logo and then returning to the 0% battery screen and then off. i disconnected it from there, plugged it into my laptop where i could only get the micro-usb led to blink... it would not power on at all. I then got my Blackberry Torch's little usb wall adapter and tried that out and it worked like a charm. phone loaded up the way it was intended to.
Now as far as amperages go, for the dock i am unsure, it states on the wall plug it has an output of 1600ma, but for up to 4 devices... i am unsure as to how much power is restricted to each port if any. I only had the bold and backflip connected to it. My laptop has powered USB ports which deliver 550ma's each which is typical and in my experience often not enough to start a device from 0%. My BB wall adapter is 750ma's which has to be my personal preference. I actually refuse to plug my Torch into a USB port until i know it does not supply over 750ma's for fear of ruining my battery like had before on other phones not designed to use a 1amp charger. I am assuming my Backflip has the same idea.

Charger died

So my co-worker has an Asus transformer like i do and he is on his 3rd charger for it. So i have been lending him mine while he waits for his new one. So last night he borrowed it and when i went to charge mine it no longer works. Are the chargers really this faulty or could it be his device that is killing the charger?

After charging my tablet for a while or overnight the charger does not work either.
So what I do is either wait it out or throw it in a ziploc bag and toss it in the freezer(I can't remember where I found this tip but it does work).
The charger gets excessively hot after 2 hours of straight charging and as a safety feature I believe it shuts off. Throwing it in the freezer simply resets the charger I believe, and it is only for about 15 minutes.

They definitely have different versions, the later version 0B-2LF, 0B-3LF (?) are supposed to be less failure prone.
You can always make a Do It Yourself (DIY) charger with a wall charger and USB A Female to 5525 Plug Female Power Adapter.

I’ve got similar experience – when I’ve tried to charge tablet second time after few hours of playing with it, when I’ve plugged charger in, icon didn’t show me expected “charging” icon. At first I’ve thought that was faulty cable but plugged to PC worked fine. Then I’ve found some info that connectors between charger and plug adaptor tend not to have a contact. I’ve taken out plug adaptor and bent slightly those 2 wires on charger, then connected the plug adaptor back. When I’ve plugged it into wall socket – it worked. I’m on 0L-1LF model.

I've encountered this problem too. At first I thought the charger was dead, but when I rebooted the transformer while plugged, it start to charge again. Maybe you should try that.

It probably still charges or has some charge optimization like my Lenovo laptop has. Mine does the same but never any issues.

I also did have to put my charger in the freezer... for over a month now it's been working fine.
Try it

Another succesful "freezer" here.
To document - My powerstrip turn off with PC and charger is plugged in to it. Tablet was @ < 20% when I put on to charge, not realizing strip was off (company in town so wife wanted it off in case room was needed for kids), got up next morning and now tablet @ < 4%. Took charger and tried multiple outlets and none would charge and charger was not warm. Tablet @ < 4% and now plugged to USB port on laptop (recongized USB Debug and Asus Sync) so it is trickle charging sort of. Search turns up this (and a couple of others) tread. Turned off tablet (to improve trickle charge performance) and waited the 15 minutes. Removed charger from freezer, plugged into wall, plugged in tablet and tablet turned on and now shows as charging.
I assume this is a hardware/software/firmware problem in that the charger is not going to burn itself out trying to push too much voltage and the reduced charge state of tablet is raising resistence and the firmware has a pointer wrong and it needs to be a little colder to be right.
No idea but thanks for the tip.

I got kinda freaked out when my charger didn't work with my tablet last time. I blamed the custom rom since it happened a couple days after I rooted and flashed a custom rom on it, and I never had trouble with stock before. But, it wasn't the charger, since I plugged in the dock and it could charge. So maybe sometimes the tablet doesn't take in a certain amount of voltage or something..? (It was fine after I rebooted.. or update roms, can't remember.)

I once thought that my charger had died but then I tried a hard reset (hold the power button down for 10 seconds) and it started working again. It's worth giving it a go before you go out and buy a new charger.

I think there is something off with his TF if it killed 3 or 4 chargers.

My charger died and no amount of putting it in the freezer or anything else would make it work again.
The only thing I did was pull the cable out attach the TF to my laptop and download files to a different Micro SD card I had bought. Plugged it back in and no workie.
Lucky I had bought another charger for a spare and had it to check the cable ..charger and make sure it what part actually wasn't working...and charge my TF.
It's at an ASUS service center hopefully being fixed.
They do go bad. Theres been documented problems with them just like the dock,, and tablet. When your trying to build the cheapest tablet around ...parts and some things provided by other manufactures ( I know Asus doesn't make everything that goes into it) don't always turn out as well as you've planned.

[Q] [HELP]Phone will not charge

Today my Triumph seemed to be draining the battery faster than normal, though I was also making a lot more calls than normal. I have a cable plugged into my PC at work which I plugged into my phone but the driver install window didn't pop up like it normally does and my PC's network connection got very slow. I unplugged it and my PC connection was fine again. I left my phone unplugged for the most part after that though I did plug it in once or twice. I don't think it was ever truly recognized by my PC at work today (it has worked before) though I'm not certain.
When I was about to go home I noticed my phone was off. I knew it was low on battery so I assumed that it had turned off due to low battery. It couldn't have been off any more than 30-60 minutes. I didn't think it should have turned off already for low battery yet though.
I plugged it into my car charger and my phone refused to turn on. About 20 minutes later i unplugged my phone and the red charging light was still on. I had to pull the battery. I then turned on my phone and it was working, but low on battery.
About 45 minutes later I drove home with my phone plugged in, but I didn't check to see if the charging light was on. The phone was still on. When I got home I tried plugging in the phone and I noticed that it was not charging. It still isn't. I have tried the following:
Restarting phone
Plug in while it is turned off (charge light comes on but not charging animation, must pull battery for light to go off. phone will not start while plugged in or charge light is on)
Try plugging into computer rather than wall
Try car charger
Swap battery to stock battery (I use an Anker battery rather than the stock. I haven't used my stock battery for a few weeks to a month. It should have been fully charged but only had less than 50%) and try everything again with same results
Right now I have my Anker battery in which was nearly dead (below 10%) plugged into the wall with it off hoping it will charge. My phone is mostly stock other than I rooted it using the b_randon14's method, installed b_randon14's tweak mod, and flashed in the Sprint PRL using a method from howard forums with the 60681 version. I had links but had to remove them due to not previously posting on this forum.
I noticed the usb cable is not solid in the prot on my phone, but it never was and doesn't seem any different. For example I can move the cable back and forth a little bit while plugged in. It remains plugged in when I do this and while the phone is off it knows it is plugged in obviously. Any ideas?

Ok... I left it plugged in while off for an hour then it started working... very odd. Nevermind then I guess, lol.

Saw this thread, was going to suggest that. Your issue seems to be one that happens across all sorts of devices that have rechargeable batteries, even Android phones (and especially $&!t MP3 players that you'll find at K-Mart). I once made the mistake of buying a $30 MP3 player that refused to turn on once its battery dropped to a certain level. Twice. From K-Mart, of course.
Thank goodness for returns.

I am still having issues and it is really frustrating. Sometimes it will charge when on, some times it won't. The only thing I think MIGHT be common between when it does and doesn't work is how much battery is left. I think it might work more often when the battery is closer to a full charge. What I often do is plug in the phone, shut it off, it will charge but charging animation isn't there and I cannot turn it on until the charging animation shows up. I think it only shows up when the phone is fully charge or close to it (I've only ever seen it when it is fully charged).
Unfortunately I don't have a lot of concrete information on this as i haven't had much time to troubleshoot and verify any of my suspicions. I do know that USB Debugging has nothing to do with it and clearing my battery statistics didn't have any affect either. This issue is very frustrating and I believe are all software based, not hardware.
Any ideas or pointers?

Out of curiosity, have tried a different USB cable? I know that you talked about switching chargers, and I couldn't tell if this was just the base unit and you plugged the same cable in or, if it was a completely different charger and cable.

I have a wall charger with a usb cable at my office, a wall charger with a (different) usb cable at my house, and a car charger with its own non detachable usb cable. All have the same issue.

Why did it discharge, and why won't it charge anymore?

Two days ago, I turned my Infinity off and docked it. Both batteries were fully charged. A few hours ago I picked it up again, and the tablet wouldn't turn on.
I plugged it into the wall outlet. It started charging and I was able to turn on the device. It had 0% charge, and the batteries on the dock were also dead. What I don't understand is: how can the Infinity and the dock discharge completely in that time even though it was supposed to be off?
I left it plugged in so that I could use it while it charges. After some time, it asked me to connect the charger and then turned itself off due to almost dead batteries. Cable was still plugged in, though the charging light was off.
Tried connecting the cable to the dock, no light. Tried connecting the cable to my computer, it didn't work. So, the cable must be faulty, right? I can still turn the Infinity on, it'll boot normally and turn itself off after it's reached the lock screen. There's a red exclamation mark on the battery icon that wasn't there in the first time I turned it on, does it mean anything serious?

I had it drain to zero once overnight. Wasn't completely charged but it was strange... hasn't happened since in fact it generally has very good battery life.
I would definitely try a new cable and or charger.

Yeah, I've asked the store for a new cable. They'll have to mail it to me, so my tablet will stay dead for a few days. Now I know why propietary connectors suck.
Anyway, it seems I'm not the only one that had problems with the charger. Many people have reported overheating, but that never happened to me. The adapter that came with my Infinity seems to be a newer model; the plugs can't be folded or detached.

Charger: I had that happened several times to the SL101. Turned out I had something else plugged into the USB and the adapter was overloaded and tripped. Unplugged for a little while for it to cool down and reset itself.

What do you mean you had something else plugged into the USB?
Anyway, I've left my adapter alone for quite some time. I'll go see if it works as soon as I get home.

I was charging a small 700 mAh battery through the USB. That was enough to trip the AC adapter.

Pixel 2 is dead?

So it was on last night and when i woke up this morning it was dead,but i powered it on to see what time it was, then it turned off again right after, i figured dead battery no big deal. So i go to charge it and go back 15 mins later to turn it on as i'm expecting a text message and it won't turn on just a red light flashed once. i tried 4 different outlets checked the connector for lint or dirt nothing, its been charging? for 45mins it should be almost done but it wont turn on. i tried pwr+vol up, pwr +vol down nothing. Sucks cause i don't have any other USB type-c chargers or cables and everyone elses phone is Micro usb and my other family have ****inn iphones. Also it's new years tomorrow so no stores are open. Sigh any ideas?

Had the same thing happen. For some reason once the phone is completely dead the oem charger does not charge the phone. I had to use a USB a to c cable I bought at Walmart (for data transfer) and plug it into my oem nexus 6 wall charger base to get it charging and turn on...

Mine Pixel 2 has just died today. Had 30%+ of battery. I was using gmaps and suddenly found screen switched off. Tried to turn it on but since that moment, no signs of life at all.

I had similar problem. Morning no alarm and Pixel 2 totally dead. Now I have new piece.

my factory charging cable quit charging my phone as well
