[Completed] My android phone restarts repeatedly - XDA Assist

I have Lenovo a806 (Golden warrior). I have been using it since 1.5 years but now it has started having problem of restarting itself repeatedly. I have been using updated avira av for any malicious attack but it didn't showm I uninstalled recently downloaded and installed apps to make sure if it was the cause or not. But no luck there. I even factory reset my phone and yet the problem is still there. But I found a suspicious thing in my phone that dolphin browser(which is not my phone's in built app when I purchased it) can't be uninstalled and it says it is inbuilt app. Another problem is that few days earlier my du battery saver showed high battery temperature asap I opened up a game like coc. My battery gets heated up little faster than before.
So, I concluded myself there maybe two problems. Either it has virus or my battery has got a problem or even maybe other problems. I hope you guys could help me if those are the really messy problems or it is something else. and if it is battery's problem, how can I confirm it?
P.S.: My phone is not rooted and my phone auto switched off asap I removed from charging an hour ago. Now it auto switch off sometimes even when charging.

Xperia SL - baterry drain during night

Three nights ago it went down for 4-5% - that's good.
Two nights ago it went down for 15%.
And last night it went down for, again, around 15%.
Didn't install or start anything new during these 3 days.
Only things that I installed and are in use are viber, illumination bar pro and remind me. (I can't see that they are the reason, because they were aslo running when battery went down for 4-5%)
So, what could be reason? Could some preinstalled apps be the problem? Could root and removing them solve the problem?
Or something else?
Thank you!

Hi,
Rooting is the not the first solution....
first take backup & do factory reset of your device .... observe few days.... if problem persist.... then we we can suspect pre installed application.... also some time hardware issue... if in warrenty..check with manufacturer...
if still issue... plz post...
-rkk
Didn't reset or root (flashtool won't recognise my device), just turned off and then on, and last night, only 4%.
If no new apps installed on your phone during tests, it is possible that your internet connection signal (wifi or 3G) is fluctuated. Whenever the phone sync, weak connection signal may cause it to spend longer on the same task, sometimes generate heat while trying to keep the connection alive.

Heat, reboots, and battery drain, oh my!

So I returned my z3 today, for another.
I was having issues with the device running very hot, rebooting about ever 3 minutes, and draining the battery within about 2 hours.
This was happening even after a reset, disabling most apps, etc. Etc. I tried it all.
So I have a new one here in my hands, and.... Same issue.
Anyone else having this problem, find a fix?
You must be having bad luck with this phone. I do too, but it's the camera issue. What are you running? Is it doing that on idle? I want to try to replicate that issue to see if mine is doing that.
Nothing honestly. It was going it even after I had disabled nearly ever app possible. I let this one sit for awhile, update everything, etc. Seems fine now. But the last one was fine for about week so we shall see. I couldn't find an issue, even the battery stats looked perfectly fine. Which is odd because I unplugged the now returned one at 9am and by 10am this morning it was down to 18% battery left.
Have you use PC companion repair your phone? It must be software issues.

Once you got issue with Xperia phone try these solutions
1. Factory Reset
2. Repair firmware By PC companion
Note: If there is software bug in firmware the issue won't solve with repair firmware >> you should search some sites like XDA to see another reports
>> After Repair firmware by PC Companion (if problem remains) you can be sure that there is a problem with Hardware side. so take it to Service Center

LGLS996 random reboot

Hi guys,
I have my new phone bought on ebay (I forget the exact seller because was a friend of mine who bought it, i am overseas in Cuba) and from the beginning some icons are not painted correctly.
The thing has gotten worse since the phone restarts for no apparent reason and no matter what I am doing. Originally it came with the ZV8 software version , but i have permanently the notification for a downloaded update to install. So i do it and now i am with ZV9 version and has maintained the same problems.
I need any help you can give because i can't return the phone to US and here there is no official warranty service from LG that i can use.
Thank you and best regards.
I had a similar problem with my G Flex 2 after it updated to 5.11. It would randomly reboot and restart with optimizing apps almost every time. It did this at least twice a day. It would also have issues installing apps sometimes saying there was no storage available. When it did install apps sometimes they would crash when opening them. Eventually after resetting and erasing my device four times the issue went away. I read that sometimes this can be caused by a bad battery. See if your device stops crashing when it's plugged in. If it does it's probably the battery. If not try resetting it a few times in a row and see if the problem is still there.

Hi probaina, thanks for your answer!
By chance yesterday analyzing what happens I thought it could be a battery problem, because when reboots occurs and I watch the battery use log sometimes I find out that the percentage of battery drops for no reason. For that reason yesterday I left the battery ran out completely and then pluggin the phone on charge overnight in the hope that this would solve the problem. But today it has restarted twice already. I'll try what you say to keep the phone plugged in to see whether the problem occurs and I will keep you updated. Once again thank you for your time and response.
Best regards!
PS: Sorry about my english, is a work in progress!

HTC One m8 troubles

Hey all,
I've posted this on a couple of other forums too (so some of you may have seen it there too) but I'm still struggling with my issues.
I stupidly dropped my phone and when I picked it up it was off which I thought was strange and ever since then the phone has taken forever to charge, when not on charge and turned on it runs super hot and generally keeps restarting itself, also the android system usage is really high and each app I go on the usage seems to be double what it used to be. When hitting 99% charge (when the phone is off) the battery symbol shows up with an exclamation mark in it (seems concerning).
I've browsed the web for answers and I've done everything suggested bar the factory reset as I don't think that will fix it as others had no success so I'm a bit stumped and I'm wondering if anyone could help. (I would try this eventually, but I can't seem to make it connect to my PC to back it up)
Thanks in advance

You're dealing with some kind of hardware damage, you probably should take it to a reputable professional service shop.

dicussion on note edge reboot issue....

Hello Note Edge user...i have seen in some threads that post 6.0 upgrade many users are facing reboots issue @ 30% (some where around) battery level and some not facing even @10% ...Hence i have created this thread so that they can help us in any way... Its an request to non rebot user to provide their firmware version details so that we can try it out..
Also anyone can suggest whether there is any way to overcome this.
Thanks in advance..

Hey man, sorry to hear that you are also facing the same problem Can you share some specifics?
- Have you ever rooted your phone?
- Does your phone shut down within seconds of opening snapchat, regardless of the current battery level?
- Have you experienced totally unstable performance, like sudden battery level drops of 20-30%?
- Have you tried going back to a lower firmware?
- Have you tried removing the SD card, if any?
Let's work together to understand our problem better and hope for a solution

Hey man,
So,
Couple of things about my problem so that we can maybe point out similarities and maybe a common cause.
- I had my phone rooted the first time the problem appeared (android 4.4.4)
- I updated my phone to Lollipop, and that's when i first started getting hints of this problem
- At first i thought, it was a charging issue. but it started happening more and more often.
- now, it pretty much happens everyday and is making my life miserable.
- I started to notice that my battery roughly dies around 37%. From what i've read online, this battery level can be different from person to person.
- From the moment it dies, it restarts itself and goes into a bootloop.
- The moment i plug it back in, it show a battery level of 0%.
- And then, within a few minutes, the battery level goes back to where it initially was when it first died.
- My battery discharge was really turbulent, the whole graph was a mess. I would see sharp drop till I would reach the dreaded 30% area.
- I noticed that right after I enter snapchat, it takes about 3-5 seconds for the reboot to happen. This happens regardless of the battery level as it has once happened to me at about 80% battery.
- The best thing that ever happened to me was when i first took out my SD card. It was 64 GB samsung sd card so i thought it would really mesh together well. I never thought about it being a possible cause. Boy was i wrong, turns out my battery performance almost returned to normal. Got to about 75% after 9 hours. No snapchat but again around the 11 hour mark. I launched chrome and the BAM, it happened again :'(
- I decided to unroot and return to 4.4.4 thinking that a custom kernel was the problem.
- Still No Luck
I have read many places online that it maybe an issue with the battery. But, I refuse to believe that is the issue. i have also tried another battery. although i think it may have been fake. Haven't tried a replacement OEM battery yet.
I would suggest a few things you can do:
- For starters take a screenshot of your current battery usage charts and then once the problem happens, remove the SD card and charge your phone while powered off and report back with another screenshot so that we can compare and see if removing the SD card has had any positive effect.
- Please clarify if you have ever rooted? sorry I was unable to fully understand from your answer.

Do u mean by installing this ur battery last upto 0%. Without reboots / bootloop....
Can u confirm ur model no and firmware version.
Guys after a lot of search found something to save much more battery life, worked for me, give a try:
1,open dialer and dial *#0228#
2,after dialing *#0228# the battery status menu will popup.
3,hit ( quick start ) at bottom of the screen in red color
4,hit ( yes ) and go to settings/battery and disable fast charging for 1 charge only.
5,power off the phone and charge to 100%.
6,turn on the phone and if it shows 97,98,99 plug in charger again and charge to 100%.
7,once it charge to 100% unplug charger and this will create new battery calibration status automatically.now you can enable fast charge again.
8, Next go to play store and download wakelock power app and install it. Open the app and hit (PARTIAL WAKE LOCK) as in screenshot below.
This app will help the cpu to run much more efficient and smoother and also prevent device from over heating and this app does not require root access.
Download wakelock power app link below.
https://play.google.com/store/apps/d...u.thedarken.wl
THIS METOHOD WORKS ONLY WITH STOCK OFFICIAL FIRMWARE IF YOU ARE RUNNING AOSP ROMS/CYANOGENMOD ROMS/NOTE7 ROMS/S7EDGE ROMS/ OR OTHER PORTED ROMS DIALING *#0228# MAY NOT WORK. (SOME PORTS COULD WORK LIKE Dr. KetanRom, EnhancedRom, RamRom.)

Thanks for the help,I appreciate it but unfortunately it's still restarting and getting stuck in a boot loop and this continues until I plug my phone in. This battery is only 8 months old. And this problem didn't start until the last security update. It's getting worse every day. It started happening at 80%, now when my phone gets to 98% it goes into this boot loop. I have the Verizon version. Maybe I'll try a factory reset

Now you're getting somewhere,from the sounds of it.
It almost sounds like the security system in the phone is seeing something it doesn't like on startup and doing a reboot to try and purge it.
I really hate Samsung's built in security.
