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.

HAS THIS HAPPEND TO YOU????:confused
I forgot to unplug my phone from my pc and connected to my house charger.
I was adding movies and music to my phone I noticed the other night the phone charges slower when connected to computer.
The battery icon was showing it was charging on the screen.
before I knew it I was at 13-15% whenever that warning comes up on the screen.( o charge phone)
I left my house for 3 hours and I was was using car charger, next it dies on me I was like,
WHAT IS GOING ON???
I tried to turn on the 4 ot 5 times phone would not turn on. I left the phone on the car charger for 15 minutes before I trying again.
I turned the phone on and it did not go to boot screen, but I saw a red battery
with a yellow exclamation point.
Battery died on me and will not turn on.
Just giving advice , becareful that you have a good car charger.

It is a known fact that almost all devices charge much more slowly when connected to the usb as compared to being charged from a wall charger. This is nothing new.

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.
I have an iPaq 111, part of the 110 series. It's been stored in a closet for over two years. I hooked a batter charger to the battery itself (outside of the device) to charge it up enough to be able to take a charge once I put it back inside the device.
Once I did that, it powered right up, and everything worked perfectly. Then I went to unplug it, and surprise to me, it shuts off.
I've tried EVERYTHING, HP doesn't even publish there ROM. Found a setup utility to download to my PC to access my iPAQ, but it's in German, and high school was a long time ago so it's hard to understand; but what I can understand enough is that it cannot find a device. Same goes with the extension I installed through HP's website, it only finds my HP computer.
I've plugged it into my computer and the light is GREEN, suprisingly, but it does not turn on. If I plug it into the AC power adapter, it DOES turn on, stays green, and once on the homescreen, shows battery at 100% (was 23% onwards today when I was charging it). My voltage meter shows about 4 volts coming from the battery. Contacts on all ends are clean. ROM issue? Yes, I have tried soft and HARD resets.
Any help will be much appreciated. Please please please! THank you!
Battery is not fine, its dead. The proof is the fact that on AC power it turns on, but not when connected to.USB. AC power has enough amps to directly power the device, USB does not. When connected to USB power is indirectly drawn, as the phone attempts to use battery power for operation while charging it at the sametime, thus lessening the total draw. It still however needs battery to work.
Basically, the battery is dead. By a new one of eBay.
icenight, THANK YOU for the reply, it was so quick. I have figured it was the battery, BUT:
I've checked the battery with a voltmeter and it shows over 4V- using my good Fluke. Also, when it's plugged in, it progressively showed the battery charging and it's now at 100%...
Are you still thinking it could be the battery? Not enough amps from the battery? I hate to sound cheap, but it's more about the wait- I want to eBay this iPaq since I don't use it and it keeps getting in the way!
Thanks again
iPaq still not working
New battery arrived. Still does the same thing. I've read around and it could be the ROM, but it wont stay on when plugged into the PC USB port. Computer sometimes makes a noise when I plug and unplug it though. Even put a homemade "in-line" power supply to it using a 5V 1.5A adapter. This allows it to stay on when plugged into the PC usb, but there is no communication. This thing is a pile of **** I tell ya.
Any help would be so much apprecaited. Thank you so much. I can barely get past these "captcha" thingys.
Regards,
Robert
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.
New work phone Moto Razr HD Maxx. I got it yesterday, it had 80ish% batt life. Left the chargers at work yesterday so I plugged it into my pc last night via usb to micro. I only glanced at the screen but I noticed it was still "discharging". I unplugged it and plugged it pack in and noticed a very small change in the MAH reading but it was still "discharging". I also noticed that I didn't get the normal audio notification from the pc that signals a USB device connecting but i wasnt concerned and went to bed. This morn the battery was about the same(30ish%) as the night before. I just assumed the problem was the USB ext that i was using so i removed the extension plugged it back in for a few hours. I disconnected and made some calls and got a 14% batt warning shortly after. WTH! so I drove to work and picked up the chargers. used the car charger for about 30 min and I was back up to 30%. I used the phone for a little while and again I got the 14% warning. I picked it up off my desk looked at it and set it back down. 20min later I picked it up to go put it on the "home" charger it came with and it was already dead. I have had it on the home charger for 1 hour and the car charger for 10 min and it will not come back to life.
Any thoughts? Just a defect? or am i missing something extremely simple? You just press and hold the top button on the right side to turn on right? Is this what I get for turning down the iphone on the grounds that every single person in the office already has one and I wanted to lead a revolution?

Yeah you just press and hold the button to turn it on. Sounds as if maybe there's something wrong with the USB connector on the phone, since the computer isn't recognizing it. When you plug it in to the computer it should trigger autoplay like plugging in a flash drive.
thanks youtube for telling me how to soft reset, phone is on now and charging. Not sure why it wouldn't charge before but whatever, the revolution is back online

So yeah, after soft reset the Moto is charging from the "home/AC charger". While that was going on, I plugged my old HTC HD2 into the pc with the cable that didnt work with the Moto and the HD2 took a charge. I took the USB from the supplied Moto "Home/AC Charger" and plugged into the PC and the PC is now charging the Moto. I must assume that the leads within the Moto supplied cable are of a larger gauge and carry more current than standard USB to Micro cables? Whatev... the phone works now I guess. I still wonder if the iphone would have been a better choice. lol
Have you updated your Motorola drivers on the PC?

I guess I haven't. I just wiped my PC and installed W7 so I didn't want to install anything until I knew the PC was stable and updated. Anyways, the Razr has been going dark at least once a day. I am about to plug it in and update., Will LYK if it helps the situation
