Battery death bootloop! - Xperia Z2 Tablet Q&A, Help & Troubleshooting

Im on a trip, and my battery died. When I got to the hotel, I immediately plugged in my tablet. As soon as it got to 1%, it started booting up, but because of how much battery it uses just to boot, it basically died a second or two after it booted up. Then, it repeats. As soon as it gest 1%, it starts turning on again, then when it gets to the lockscreen, it powers down. It's like a bootloop, but I can't get out of it :crying:

You try holding the pwr button for about 10 seconds or maybe longer when it's trying to boot? It might force it to just shut down.

There's a "forced Shutdown" button right by the SD card slot (it's colored yellow in my sgp561, maybe different for other sub-models). Press that button for 10+ seconds using paper clip tip or similar pointed object and it will shutdown completely.
Another possible solution is to plug the charging usb cable to a high current usb charger (4 amp+) that should be able to supply the energy demand at close to 0% battery charge.

Another option will be to boot into bootloader. Bootloader uses barely any battery. When it's not plugged in and off, press and hold power+volume down. Then plug in. You could try to do that while plugged in, but likely not to work.

HELP Today my phone ran out of batterys

Now when I plug it into the charger, it just goes to the Core Cell splash screen, for like a split second then turns off, then does it repeatedly... I donnu, how to charge my phone, I donnu what to do, please help.
Pull the battery, connect power then put battery back in. This should let it start charging without trying to start the phone.

I tried that, but as soon as i put the battery back in, it'll just restart, I fixed the issue last night, I chucked my Battery into the Freezer, for like... more than 8 hours, woke up, and plugged my phone back together, and it charged, without booting up and restart
So all good

[Q]-Phone gets stuck when plugged in while phone is off

Any of you guys experience this ? I'm on ota 2.3.4 unlocked and rooted. Not sure if this is a result of being unlocked or on 2.3.4 as it's been a week or so since I charged when phone was turned off.
Before : Phone off, plug in charger, phone starts to boot into the green battery charging screen, and if I wanted to boot fully, then press power button and it boots.
Now: Phone off, plug in charger, phone starts to boot, but no green battery screen, gets stuck at first red Moto logo screen. Holding power button does not get it to continue to boot. Only way out is to unplug, take out battery, put battery back in, and turn on phone without it being plugged in.
Overall, not a big deal as I mostly charge with the phone on and can continue to do so, but wanted to see if any others who are either unlocked or on 2.3.4 have experienced the same issue. anyone?
funny. i just answered this question a second ago here http://forum.xda-developers.com/showpost.php?p=15538419&postcount=9
hope it helps!

[Q] Non-stop Rebooting

My HTC HD2 consistently reboots whenever I plug it into a power source. I was downloading my first ROM, and it couldn't finish installing into the phone or something. I unplugged it and took the battery out for 3 seconds. I put the battery back in and it wouldn't power on when I pushed the power button. Then, when I plugged it into a power outlet or my computer USB port, it began showing the pink "stick together" symbol at my boot screen and then shuts off. This repeats every 5-6 seconds. Does anyone know what I can do to fix this? I have already done a hard-reset on the phone, but the problem persists.

SM-T560 charge/boot issue.

Hi,
I got hold of one of these tablets that appeared dead, left it charging overnight and it started without issue, the battery was at 67% at this point.
I then shut it down and held the Home + VolUp + Power to enter download mode as I wanted to install TWRP.
Nothing happened, but not only that, the tablet failed to boot again whatsoever. I took the back off and unplugged the battery, held the power button down for 30-40 seconds, reattached battery, still nothing, so I decided to leave it on charge for a bit more and try to figure it out later.
Later came along, and I picked up the tablet and for some reason pushed the home button 3 times and it displayed the battery icon, showing 100%, great!
It still won't boot though and I haven;t been able to reproduce whatever I did to get it to show the battery icon again.
I've tried every combination of holding down Home/VolUp/VolDown and Power that I can think of for different amounts of time and still nothing.
Had it plugged into the computer too and monitored dmesg for any signs of life and still nothing.
I'm thinking (but hoping not) that it might be a physical problem with the power button, but it feels fine when pressed.
Is there some magic trick that I don't know about that could help here?
Many thanks.,
g
EDIT: I have left it plugged in for a few hours and periodically the battery icon appears for a while (now at 99%), then disappears. Tried to switch it on with the power button while the icon is on the screen but no go, same with different button combos.

Has my LG G5 died over night?

Hey fellows,
I had to replace the power button and everything worked fine for at least 5 days now, tested everything, reboot ,shut down, start up etc.
Only had to fixate the metal plate on which the Power botton sits with some Tape so it will not wiggle around to much, in end it only helped a small amount.
At opening the Phone i accidentally ripped a really really small piece of the Vol Down click off, only the half of the black clicker is left but totally click able and responsive, antering the Recovery mode and Download mode is working.
Now to my Issue:
When i went yesterday to bed my LG G5 had around 60% Battery power left. I woke up today tried to Knock On the Phone, no chance, so i though strange is the battery empty? I tried to start the Phone with the Power button and it vibrates an the LG Logo with Android beneath it appeared but shuts down after 2secs.
I grabbed my Charging Cable plugged it in and it says Battery 0% with the Lighting Symbol, here the Same happens as well, shows it for 1-2secs and turns off.
After that it shows me The different Battery with the Loading Symbole in it and does the same as well 1-2secs and shut down.
Download mode does the same, shows it for 1 sec and turns off again.
Recovery mode does the Same but sometimes i get to the second choice if i really want to wipe user data etc.
I took the Battery out, kept pressing the Power button 40sec+
Took the battery of the Modular and clipped it in without the Battery, after that it shows me a Battery with a red question mark on it, but the Display stays on.
I forgot to added, even if i keep charging it it says 0% and keeps on the same behavior. Only gets a bit warm nothing else.
Now is my Question is my Phone dead? Do i need to get a new one?
Has anyone a Idea what i could try?
I would really appreciate help with this.
