Why won't my XT720 start up?
When it is connected to my charger, the four action keys light up. Despite leaving it to charge overnight, it appears that the battery isn't charging. The phone won't start while it is charging, neither when connected to the mains or to my car power supply.
I bought a new battery without any improvement.
When I access the bootloader screen it says there is too little power in the battery to program the phone.
The phone is not recognised by my computer when connected.
The phone is running Froyo 2.2. with Dexter rom.
I would be very grateful for any suggestions......apart from binning the phone!
Thanks!
I think the phone likes to selfboot with too little charge. See if you can shut it down cleanly so it won't autoboot. It's annoying but you may have to watch it very carefully to catch it when it's trying to boot because it will drain itself back to death very quickly.

Hi Oakham, do you have any update to your case? I have the same problem now.
Yesterday, I noticed the battery bar went down to orange region (about 30%?). I plugged it to the wall for about an hour (the charging symbol showed up). Later I found out that the battery bar did not move (still stuck at orange region). Later the night, I tried to charge again (the bar was red at about 15% or less). The charging symbol showed up. Later I checked, the battery bar did not improve but declined. The phone eventually went out of battery and turned itself off.
I tried to continue to charge using both the wall outlet and PC USB. No luck. I could not even power up the phone now. Did you manage to resolve your case? Anyone got the same problem and found the solution?
I thought about buying a new battery to try, but then I saw your post, so I hesitated.
Thanks.

I've had this problem. Watching the phone closely while charging and pulling the battery whenever it starts to boot works. After about the fourth time doing this I got a battery charger from amazon for ~$5 because it's gently loving annoying.

Thanks for your advice.
So when you first bumped into this problem, how did you get it back to boot up?
I followed your advice to watch it while it's charging. When I saw the motorola logo showed up, I pulled the battery. Then I plugged it back and let it charged for some more time. Then I tried to power up the phone. The motorola logo came on and then the big battery symbol came on saying it's 100% full (but i knew it's not). Later, those 4 soft touch button lid on. This cycle repeated. And I'm clueless.
Please let me know the steps you took to recover your phone.
Thanks.

Once you get into the system use 'power off' from the menu. It won't autoboot then and you can leave it in the wall overnight. I think. A voodoo doll may work, too. It can be really frustrating, but I've been able to get out of it every time so far. Like I said, I got sick of this game and found a battery charger for pretty cheap.

Try deleting batterystats.bin and doing what M said.. can you get to open recovery and charge from there?
I also had the 'M' logo screen, stuck on-screen when the charger was connected. There is a post which suggests, for this, 'Pull battery.2) Insert battery and hit power button;3) As soon as you hit the power button, hold the volume up button down until the unboxing logo comes up.'
As my phone is still under warranty, I sent it back to see if there is a physical problem. I'll try the above suggested solution when my phone comes back from 'Motorola', whether or not it is repaired by them! I've also bought a battery charger for the phone's BP6X battery from e-Bay (£9.50, including another battery.)At least I will then know that a battery is fully charged before I try fixes.
Thanks for the other posts/replies!

In my experience OR drains faster than it can charge.
Sent from my XT720 using XDA Premium App
Damn!
I had about the same. Battery got drained down from 80% to 5%. Then the screen for "please plug in for charging" appeared. Some moments later the phone went dark and now I can't get it to work again. It doesn't react on the power button. Even when plugged in the charging-symbol doesn't appear. I can't turn it on. Sucks!
Any ideas?
My phone has been repaired by Motorola, under warranty, and returned after four days. Accompanying report is brief: 'Software update and screening'. Seems to be working fine.......just like a brand new phone!
This morning i find myself in the same situation. My phone have the soft keys iluminated but it didint work.OMG... what happend durring the night.So i tried to boot the phone but nothing happend,and after reading tje post on the problem i have tried to remove the battery and put`it back, tryed anothe reboot, and holdind the buttons power+vol up. Nothing worked. But when i have tried the combination power + vol up + cammera shutter and plugged the cable. at first nothing happend. but after i have relesed the buttons the logo apeared and started charging. after that i powerd on my phone normaly
My phone does that everytime it charging and I remove the plug when it's in sleep mode. I have to remove the battery and it's power on normally.

im running a miui build from abt 2 weeks ago, idk how relevant that is... BUT i let my phone discharge completely til it died. now when its on the charger, it boots to the miui screen, sometimes even the lockscreen, then craps out. i get that the battery is too low to hold a charge, but wat can i do? i tried charging in download mode, but it eventually reboots. custom roms wont allow us to charge the phone while off, so anyone have any suggestions, as i am in this constant bootloop????????
Sounds like you need a new battery, the phone is supposed to shutdown long before there is damage to the battery but a completely discharged lithium battery may never take a charge again, but if you can't charge with the phone off then you may have other issues.
Id hop on Ebay and find a replacement battery. Them work from there

This is my experience i am on miui also and the other day I had the same thing happen and I just did the three button trick to boot into recovery and left it in recovery for about 15-20 mins then reboot and it started to charge. Hope this helps.
Yikes, I guess ill have to remind myself to never let my battery deplete. Although I thought it was recommended to let battery cash in at least once per month.

howd you get it to boot into recovery? when it boots, it goes straight from the circular dotted charging/loading symbol to my miui boot animation, NO samsung screen so i dont know when to let go of the power. ive tried at random times, but no dice. i dont have enough juice to unplug, boot into CWM, then replug

Pull and replace the battery and Hold both volume buttons and the power button at same time.... Phone will reboot, once you see samsung splash screen let go of power button while still holding both volume buttons and cwm should come up.
I Should have said while being plugged in. Mine was via usb

i never got to the samsung screen, but your first suggestion worked. when it booted to the lockscreen, i quickly unlocked, turned off wifi, gps, and adjusted screen brightness, then i wa able to boot into recovery and let it charge a minute... thanks for ur help & to the other the guy that tried
I've had this happen also with a totally discharged battery and CM7. Booted to download mode and wiped with Odin, reflashed CM7.
I had this happen with CM7 a couple weeks ago. A couple guys asked if I was using the actual Samsung charger and pointed out that it has some charging internals that work with a low battery situation that other chargers may not have.
So, were you using the Samsung charger or another USB power source?

I use my Galaxy Tab as a navigation in my car, last night i was watching a movie and i did not charge it, it was 8% left battery life,
This morning i mounted it in my car, put the GPS on, tried to charge it with my car charger, it kept notifying me every 5 seconds the tablet is charging, and not charging, (keeps connecting and disconnecting) till it gave me a black screen, since i was driving i ignored it.
when i reached my destination, i was able to put in download mode, by hitting volume down and power, then i hit volume down to restart. then it gave me a black screen again, tried to do the same thing then i hit volume up to get me in download mode, then i powered it off somehow, i do not remember, now i am stuck in black screen,
had it on the OEM charger for an hour, it does not seem to be charging, i am not able to get in download or recovery mode.
i have had this tablet for 3 weeks now, never flashed a custom rom or rooted it,
is there any way to put it back to life? please please help!

Why are you trying to go to download mode, simply plug to an AC power outlet, leave it for seconds & keep pressing the power button for around 3-4 seconds, it should boot up normally.

thanks
Prime
No, the plane didn't do anything to the phone.
Did the battery die? Did you stick the phone on a charger after it turned off?
Best guess is that it's overheated to the thermal shutdown limit.
Leave it a while then try powering it back on

na, when you hit the safety shutdown temp, all it does is shut down, you can boot it right after. ive reached it many times(on purpose), it works.
what the op is describing sounds like the rlod on the nexus 4(red light of death). it happens when the phone thinks it went below 0%. on the n4 there are two solutions, one works sometimes, the other all the time. the one that works sometimes is leave it on the charger for several hours, then try to boot into the bootloader, then shut off the phone from there and keep charging. the method that works 100% is to remove the back cover, disconnect the battery, then reconnect it. this is a hard reset for the battery, and works 100% of the time on the nexus 4.

You may want to give this procedure a try, its copied directly from Google's product support page for the Nexus 7.
Make sure there isn’t any dust or lint in the power port.
Using the original power adapter and USB cable, plug your Nexus 7 into a functioning power outlet. Nexus 7 has specific power requirements, and the USB cable and power adapter that are included are designed to meet those requirements.
Ensure the power cord is securely connected to the tablet and the power adapter.
After 1 minute, check to see if a battery icon appears on the screen.
If the battery icon appears, press & hold the Power button for 15 to 30 seconds to see if the device turns on.
If the battery icon doesn't appear, try accessing the Android bootloader menu:
Press & hold the Volume down button. While holding Volume down, press & hold the Power button for at least 10 seconds until you see an Android robot and the word Start on the screen.
Press the Volume down button until Power off is highlighted. Press the Power button to select that option.
Disconnect the charger and reconnect it within 10 seconds. A battery icon should appear on your screen.
Once the battery icon appears on the screen, allow your tablet to charge for at least 1 hour before turning it back on.
returned it

I got a new one thanks for all your help
I just had a red blinking light and no charge indicator situation, as well. Nothing seemed to work: plugged it in for 20 minutes, unplugged it for 20 minutes, plugged it back in...and after another hour on the charger I finally noticed the blinking red light had gone away, and hitting power brought up the charging indicator as normal. Booted right up and has been fine since.
My Nexus 5 just started doing this. I was in the middle of playing a game while my phone was on the charger (Brave Frontier) and suddenly the screen went dead and I had the red flashing light. I'm guessing I was using the juice faster than the charger could fill it so I killed it. I couldn't get the battery indicator to come back but as I was typing this the red light finally stopped flashing and the phone rebooted.
This happened to my N5 today. I was on a Hangouts video chat while plugged in from wall charger and I noticed the battery was actually draining rather than charging. So I figured hangouts was discharging the battery faster than the charging. Eventually it went to 0% and stayed that way for a while and suddenly the screen went off and the LED started blinking red. Followed the steps posted here, plugged in, left for a while and the blinking stops and phone boots up.
Never Hangout-ing with low charge ever! D:
I couldnt turn it on . I got 1 or 2 blink led while pressing power for 10 seconds (this only if it is plugged), it doesnt do anything if unplugged. Tried 2 min hold power down, power and volume down, and several other options. Tried several charger, LG, Samsung, RPI2 (5v 2a), pc/notebook usb, and of course the original charger. Left it for charging all night, and several hours during the day. Nothing seems to work, battery still cold afetr so much time charging.
A few minutes ago, i removed the battery and plug it to a charger and it seems it wants to boot, see several blinks but the screen never turns on so the phone, after a few seconds it stop blinking.
What is going on???? Any help would be helpfull

Did you flash or modify something before this happened?
You might have to flash your stock firmware.
