could I get some help here,
I have an LG L9 P769 that started randomly powering itself down, and it will either stay off until the battery is pulled or it will start to power cycle it self and only make it to the last boot screen before restarting the cycle. is there anything I can do to remedy this short of buying a new phone or battery? this phone is only about 5 months old and started this behavior about a month ago, but has gradually started doing it more frequently to the point where now I can barely get it to completely power up and stay on before it starts doing this. any help would be appreciated.

Does anyone else experience their GS2 randomly powering off?
I just got this phone yesterday and it did it twice yesterday while in my pocket and twice today. Just recently I had an incoming call (phone was in vibrate mode) and about 10 seconds after it started vibrating right as I was about to answer the call the phone shut itself down. Completely.
I had to long hold the power button to completely boot the phone back up.
I'm on rooted stock OTA 2.3.6 but it was happening before the update. Anyone else have this problem?

Nope - I suggest taking it to the AT&T store for an exchange.
Check to see if there is some movement of the battery. I read here or another forum when I was searching regarding random shutdowns and thing that seemed to be similar was that the battery did not fit very tight and could move slightly and cause a reboot.
Simple fix is to insert some paper between the battery and the case to keep it tighter in place (opposite end of the battery from the contacts). No reboots for me since I did that earlier this week.

If the battery is that loose, the device is probably defective.
i went to radio shack where i bought it from yesterday and after a bit of a struggle i managed to get them to exchange it for a brand new one.
i also read about the loose battery connection but i felt that if that were the case i do not want to spend the next 2 years or so (i hold onto my tech for as long as possible) dealing with wedging things behind the battery.
i'll update if the new s2 i got has this same problem
two times when i've woken up and checked my phone its been powered off.
I figured it was SetCPU (having the CPU at .2Ghz min/ondemand and 1.6 max)
may have made the phone turn off.

Overclocking/undervolting always carry a risk of the phone crashing or hanging.
I've recently started having this issues. It's not a battery loose issue and I do not OC / UV my CPU. Started about 3 weeks ago and has happened 4 - 5 times intermittently. Its a "sleep death" issue where the phone goes to sleep and doesn't turn back on until you manually boot it by holding the power button down for about 10 - 15 seconds. For now AT&T is sending me a new battery. This is a possible cause because with investigating this issue, I have been checking my battery stats every day by typing *#0228# and having it do a quick start. The battery percentage will always drop by 5 - 40% after the quick start, but will increase about 3 - 5% within approximately 5 minutes.

It's a known issue that if the fuel gauge is reset when the battery is at a lower state of charge, it'll get thrown off and report lower than usual for a bit until it stabilizes.
I think what happens is if you do a reboot, the fuel gauge is assuming a "relaxed" battery when in reality the battery is at high load due to the boot process. So the fuel gauge thinks it's lower than it really is.
Google Maxim MAX17040 - while we have a 17042 with a few extra features, it's VERY similar in operation to the '40.
For awhile now I have been running the AOKP ICS ROM v7.3.2012 on my sgh-i777 and along with my poor battery life (which I assumed was normal after skimming through multiple forums) my phone has been freezing up (not requiring hard reboots 90% of the time) and shutting down at points in the night. Throughout the day my phone is a must and is ran like a mule. Assuming I'm fulfilling my RAM's duties, I am faced with force closes on programs frequently. Every night when I go to bed, I plug in my phone and let it idle throughout the night. The past two nights I've woken up on my own, thankfully in time for my test this morning, to find my phone off. Not just off, but completely down (requiring me to eject the power cord and battery for a few minutes and reapply the battery). When I try to turn it back on the navigation panel lights flash and seconds later the phone powers back on. This is my second sgh-i777 from AT&T after my first phone began turning itself on and off in an endless loop. The ROM build has served me well for months and all the sudden these shut-downs have been occurring. It's becoming a bother to my phone's vital importance in my everyday goings. Please help.

I would first perform a back up then perform a full wipe and reflash your rom of choice. If it continues to happen... flash back to stock to see if it still happens. If it does then you may need to warranty the phone.
Hey XDA,
My dad's Huawei G700 suddenly stopped working.
He used it for a call, put it in his pocket with about 20% battery remaining, and an hour later, the phone wouldn't boot.
I kept it plugged in for a few hours, took the battery out of it, removed sd card and sim, tried every button combination possible with no result whatsoever. Currently, upon pressing the power button, it either vibrates for about 5 seconds, or does a single vibration but the display does not light up either way.
The phone is 6-9 months old, it has always been kept in a filp case, never dropped.
Thanks for all your help!
So I have an odd issue here... I have a tmobile v10 that suddenly stopped working. Can't boot up or anything anymore. Here's some events (not in order) that have happened. I dropped my phone about 6 months ago and cracked the screen. Was fine up until about a month ago. I pulled it out of my pocket one day and it was off. Thought I had accidentally turned it off while in my pocket, so I went to power it back on, but nothing. It wouldn't boot up at all. Thought my battery died so I plugged it in, but again, nothing. for the next couple of days I was able to randomly get it to power up and boot up to the main home screen. After a few seconds it would freeze and then shut off on it's on, sometimes rebooting automatically, but never making it passed the "LG" splash screen. Any who, before all this the phone ran fine, no issues. I didn't update anything or add any odd ball apps. I got it to show some life when plugging into the computer via the lg usb cable with the battery removed, but as soon as I threw the battery back in and try to reboot, nothing.
The other odd thing I noticed is that when I threw a charged battery in it, it would kill the life of the battery (verified by placing a charged battery in the dead v10 and then after trying to boot, removing and placing back in my good v10 and checking battery life). It would always say it was either 0% or 5% when I put it back in the good v10. The batteries will still charge on the good v10 so I don't think the batteries are bad (one is a brand new LG brand battery).
I'm leaning towards the prongs being shot on the battery connector that's on the motherboard, rather than the charging port. Anyone ever have this issue or even hear of it? I did some searching online but realized I didn't even know what to look up to find what I was looking for.
Any help will be greatly appreciated and thanks in advance.
Sorry for the story, just trying to give as much details as possible. I'm sure I forgot some stuff, but I'll edit/update as I remember them. Thanks.
Hello,
I have a Samsung Galaxy Note 4 running stock firmware, unrooted and bootloader locked. Ever since a few months ago, I've noticed my phone having some problems such as it randomly shutting off around 20%. Over time, this battery percentage increased until I essentially had to keep it plugged in to turn on. Now it will be at full charge, and still won't get past the Samsung Logo or if it does, it will restart in around 1-2 seconds after getting to the phone lock screen. During this time, the battery percentage is still fully charged and nothing else is abnormal. I noticed something else as well before it got to the state. If I was not connected to the internet the phone will not restart when it runs low on battery, but as soon as I do connect it restarts. I've considered getting a new battery, but is there anything else I can do for the time being?

Edit: I managed to get it to turn on for longer than 5 seconds and turned on flight mode and now it does not turn off (while plugged in). I'm going to do a backup real quick.
