Phone Crashes - Have to take out/in battery

Hey All,
Im runing KE2 rooted, ive noticed 3 times now going to use my phone and the screen is blank, non of the buttons do anything even holding the power button.
Only way to get it going again is to take the battery out and back in and power up the phone.
Am I alone? Ive seen posts about overheating etc? if im on my own im going to get a replacment just wanted to confirm before i ring up my provider!
Cheers, Alex.

Mine crashed twice before KE1 & 2, but since then it has been fine.
Same thing, black screen, first time I took the battery out and second time it recovered by holding down the power button for about 10 seconds.

Happened to me last night/this morning. The alarm didn't sound, nearly late for work. When I woke up look at my phone it was completely blank. Nothing, nada, had to pull the battery but still nothing so I plugged the charger in after a couple of minutes the battery icon came up.
It seems the phone lost discharged the battery completely from 78% when I went to sleep doing nothing for 8 hours.

Differnt issue, on inserting the battery back in i still have charge

Yep, I also had this problem but it only happened twice. Once before when I was on the stock firmware, and once after I updated to the first firmware. Now I am on the second firmware, it hasn't happened since but only time will tell.
I made a thread yesterday: http://forum.xda-developers.com/showthread.php?t=1081546

what did bmp.net say? (im with them also)

I'm going to see if it happens again with the latest firmware before I ring them. I did the troubleshooting thing on Samsung's site too and it says to wipe the battery pins and phone pins with a damp cloth.

Won't turn on D:

So today I left my tablet to charge, it was at like 25% left, while I went to out to my practice. When I returned about 2 hours later, it wouldn't turn on. Before I had left, it was charging so it's not that it ran out of power because the outlet didn't work. I switched the outlets, plugged it into a computer, pressed the power button a bunch of times; nothing. Perhaps I got a defected unit or downloaded a bad app? I don't know :/; ideas?

try holding down the power button for 15 seconds

Hold the power button 15 seconds, let go, then try again for another 7 seconds.

Wow, that actually worked, thank you so much (held it till it turned on, about 10-15 seconds). Would you happen to know why it had just turned off like that? I'm at 81% battery now, so it turned off at some point on its own, and why did I have to do such a long power button press?

i believe there is a sleep mode/lock hiccup sometimes. I experience it with my media dock but not my keyboard dock. its weird and sometimes annoying but not too much to kill my day lol

Yeah this happened to me too. Just a small quirk.

Oh, ok, thanks guys lol I had like freaked out.

I got my Tab yesterday. Used it then set it charging overnight. Won't power on this morning. The back does get warm though. I tried holding down the power button for at least a minute and also tried the 15 then 7 approach. Nothing.
I also tried an idea from a different forum (referencing a Froyo glitch) and tried touching the screen while holding the power button.
Does this sound like a hardware fail?

I had the same problem. Held the power button for 15 seconds and then 7 and nothing happened. Held the power button for a long time. What do I do next?

Mine didnt turn on today. Tried the 15 second press procedure and nothing happened. I grabbed my wall charger and plugged it in and left it sitting there for a minute. I tried the 15 second procedure again and this time the screen lit up and was showing that the battery was charging because it was in red. After about a minute the tab booted itself and all is normal now. I guess my battery went dead since i hadnt charged it and completley turned off my tab. Thats why it rebooted itself. Nothing to worry about.

happened to me too
looks like there is a glitch ... mine was left charging today ... and it did charge but did not want to start... i did leave it on.
I connected to PC and press Power ON + Volume Up + VOlume down all at the same time and it did seem to restart ... worried there is something wrong with it though.
I bought it in USA and Im in UK I wonder if things go wrong if Samsung UK would repair it.

I've had it for about 9 days and have used it every single day. Last night I downloaded 2 movies onto it and everything was fine. Today it would not power on one bit! I charged it over night so the battery shouldn't have drained. I ended up fixing my problem by doing the following:
Held the power button.
At the same time, placed a finger on the screen.
Held it down for 15 seconds or more and it booted up!
Not sure why it only worked when I put my finger on the screen.
I ended up exchanging it either way just in case.

For some reason this keeps happening to me when I leave it to charge over night.

Every night?? I charge it every night and it only happened once. Hopefully my new one is fine.

this also happened to me for the first time this morning from leaving it on charge overnight.
however i was able to start it by removing cable and holding power for 15secs.
what could be causing this? I hope it doesn't happen every night.

I had this problem as well a few weeks ago. Samsung sent me a shipping label and told me to ship it back. I got it back in just under 10 days. They never did tell me what was wrong but they shipped back my original Tab.

Guys,
Is this happening when you leave it booted up and charging overnight or is the unit powered off and charging?
I will say that this issue has only happened to me one time and it happened under the following conditions (Ive had a Tab sense launch day):
- Battery was at 35%.
- While booted, I plugged it in to charge overnight.
- The next day at 09:00 I attempted to use it and had to hold the power button for 15 sec to get it to boot.
So, It *might* only happen if its booted with low battery and you charge it overnight. Powering it off and charging doesnt appear to cause it at all in my case.

Yes it happened while powered on and left to charge overnight. Battery was probably around 30-40% as you said.
Still doesn't explain why it would happen regardless of the % of battery left. Hence the reason it's meant to be charging.

I've had it happen very quickly. High level of charge, plug it in, walk off, come back, unplug, and it's dead, need the 15 second press to power back on.
Not a huge deal, but annoying. And a bit scary, since mine went into the "sleep of death" once already, took four days for the battery to drain enough to break the nvflash loop it was in.

[Q] When turning off, a fully charged battery has 0%

Finally receieved my Nexus 4 after almost 2 months waiting, but not really enjoying it right now.
Received it yesterday, unpacked it and I couldn't turn on the phone. So I've connected the cable into the charger and a light showed up.. After 30 min I saw a battery icon and after 1 hour I could turn up the phone.
When turned on, it showed 3% battery, so I let it charge for about 5 hours. While charging I've noticed something strange.. it was charging very slow. After 4h of charging it was showing just 16% battery and 1h later it was suddenly at 70%. After it got till 99% I unplugged the charger and tried to use the phone.
Everything worked till I wanted to restart it. The phone doesn't want to start up! Pressing the powerbutton for 20-30 seconds.. nothing happens. Tried the volume button combination.. nothing. Plugged it into my PC and after 10 min the battery icon showed up?! The battery was at 0%! The battery went from 99% to 0% just by turning it off!
I've let the phone charge again, this time the whole night (7 hours).. It was fully charged at 100%. I disconnected the charger and turned off the phone.. and again: a black screen.
I've Googled and searched everywhere but couldn't find 1 thing.. what could be the problem of this? How can my phone go from 100% to 0% by turning it off?

I have no idea what is going on but you need to contact google asap, they'll send a replacement and hopefully the new one isn't a dud.
If you want to try playing with it, plug the phone into a different charger with a different cable, let it charge overnight/12hrs and give it another shot it could be a bad cable/charger (to be honest I think this is a long shot.)

Really sounds like a hardware problem.

Your only option is RMA.

after some charging problems i have a red battery icon then autoshutoff

even when plugged in that's what i'm getting, i tried a bunch of stuff if i hold the power button for 30 seconds then i turn it on, i get a flash of asus logo, but then it gives me red battery icon again then shuts off
edit, i left it plugged in for a while and it seems to be booting up now, if anyone gets this problem try holding power for 30 seconds to reset nvflash, then let it charge for a few min and then boot up.
edit, that was only a temp fix getting problems again will report back when i figure it out

Try leaving it plugged in for several hours without doing anything. It might have just been drained too low and is having a hard time recharging. You may have a charger issue as well. When I ran into this problem once, I had to put my wall wart into my freezer for a couple hours and its worked ever since.

Battery stuck at 50%

Hi everyone, my Xiaomi Mi A1 black is stuck on 50% battery since yesterday. The phone charges, but it still got stuck.
I have tried a wipe from recovery, but it didn't helped. I let the phone discharge completely and shut down by itself and then to plug in, but when it started charching it still shows the 50% indicator.
Any idea? Thanks in advance.

Noone?

Seems too strange.
Try to let discharge until it dies, the restart the phone by pressing vol up + power btn (recovery mode) and wait until it dies again.
Then, you can connect it to the charger and wait 2-3 hours. It must be kept powered off.

Thanks, I tried to let it discharge and charged again for 3 hours, but I didn't make the recovery first. Actually, when it dies, it doesn't turn on again...I will try anyway with your method.

i would suggest you to get a replacement or a refund. this looks like a battery issue to me which is obviously hardware. so it's better you yet it repaired /replaced or get your money back. as far as i know i haven't heard anyone having this issue.

Same issue.
Hey legends, I have this same issue with my miA1 black. It's only about a month old and the battery works fine. Just the Meter is stuck on 50% and I have no battery data available in the settings menu. Any ideas?

This issue happened to me two days ago, to fix it you just have to unplug and plug the battery connector from the motherboard.

Fixed!
All sorted, thanks for the help ?
p.s. most difficult device I've ever opened! It was really stiff but the battery connection was easy!

thanks
Thanks for your help problem fixed for me.

I just replaced my lcd on redmi 7 onclite and that issue happened to me.
To fix this bug
First turn of the phone then unplug battery connector for about 5 sec and reconnect it again
