Battery issue

The other morning I woke up and unplugged my phone and the "Unplug your phone" notification wouldn't go away and the phone thought it was still plugged in. If I rebooted it would just turn off and keep going from the green batter charging icon to a black screen and back. Only way I could turn the phone on would be to actually plug it in again. Problem fixed itself that evening and the phone was fine for a couple days. Today the phone started with the same thing.
I've tried searching but couldn't find anything on this specific issue. Any insight? Thanks in advance.

Brand new ept4g and I got 6hrs of battery life its so lame I have hack so much bad luck with this bad boy but I'm not giving up.

I'm having the same problems the last few days. Also when I unplug my phone I get a red exclamation point over my battery widget, when i open the widget it says that the battery is over voltage and the red led light won't go off. Think i'm about to go see what best buy does for me. Been dealing w/ this problem for a few days now.

Did you get a replacement? I haven't had any free time to go to sprint with my problem. It is still happening often though.

I had a similar issue the other morning. Though my phone would only boot back up in recovery mode. I reflashed it to out of the box stock but that didn't make any difference. When it did boot up it would show that it was connected to the usb port but it would not be plugged into anything. I plugged it into a usb port on my computer that I hadn't used with the phone before and it reloaded the drivers on my computer and "that" issue went away. After turning phone off it would start rebooting itself immediately or with in a few seconds of turning off. I let the battery die completely and then recharged it and the automatic reboot went away, at least for most of the day, but last night I turned the phone back off and it rebooted itself. I did reroot and restore my phone after I got it to not show the usb connected or the battery charging while the phone was off icon. Just wish I could figure out why it wants to automatically reboot itself when I shut it off.

Same issue here

My Battery Monitor Widget shows a max of 1500mah? Wtf? And a measured of under 1200?
No wonder my battery life is crazy low...

I figured a way to shut the phone off and not have it automatically reboot. If after shutting the phone off the normal way and once the screen goes black but before the capacitive lights go out, if I again press the power button, the phone finally shuts down without rebooting itself. Not sure why this is happening but at least I can get it to turn off now.

I found better battery life by determining which app or apps drain the battery. I used Battert spy, cpu spy and system tuner. My problem was Touchdown exchange for Androir 2.x. I switched to Moxier Mail. I would get hours on moderate to heavy use. I got 22.5 hours yesterday on moderate use.

[Q] PLEASE HELP! Hot Phone and No signal Dead Battery

The phone randomly gets warm by the back top right (when looking at back of the phone below headphone jack) The phone DATA doesnt show, and no calls receives or sends. And battery rapidly drains when this happens, I mean within 30 minutes it goes from 60% to 0%.
I have to keep feeling the top back of the phone to see if it is warm, if so, I know I will miss calls, I reboot.

Thanks in advance

Some application is running a background process that is probably waiting in a tight loop and not sleeping for short intervals as it should. Orbot does this for me so I have to kill its background processes after using Orbot. Unfortunately the rapid drain and excessive heat confuse the charger so that it does not charge, and I need to reboot to get it working again.
You might have to uninstall applications one at a time to find the culprit.

If I may suggest try using the clean master app on the play store.

[Q] Reboot problem when not charging

I have had my P607T for a couple of months now. It is box stock no changes. Over the last few weeks I have noticed that it will reboot while using various apps. (Fliipboard, Chrome, Clash of Clans, Papyrus...) They don't seem to all be heavy graphics or network. The only symptom is that the screen starts to flash then "bang" reboot (and trouble rebooting when not plugged in). It would not be too annoying except that it will loose wifi settings and the wallpaper. I have tried different wallpapers (saw a thread blaming the live wallpapers ) Unloaded some apps (had another phone issue with FitBit and HTC blink on my N4). I stay away from CoC (my base has been raided so often now ...). Any thoughts? I am really trying to like this tablet more than my old ASUS Transformer but this reboot and reset wifi is a pain.
Thanks in Advance,
marka

Have you tried a factory reset? I'd make tmobile replace it

was hoping to avoid the reset button. Tried it and still giving trouble it rebooted while restoring apps. I bought the tablet on ebay, I don't think TMO will take it back. oh well I'll keep poking about.
thanks,

I experience exactly the same problem since the update to 4.4.2 (kitkat): The screen starts to flash, suddenly the tablet reboots. I tried a factory reset multiple times, also removed the SD card and reflashed the ROM via KIES, nothing helped so far. Also, even when plugged into the outlet for several hours the tablet didn't charge at all (I think it stopped charging when the screen saver kicks in).
A couple of weeks ago I filed a RMA request (my dealer sent the tablet to Samsung), yesterday I got it back. It was charged at 60% and when I plugged it to the outlet it actually charged (even when the screen went off). But after about one hour (the battery was still > 60%) the flashing reappeared and after a while the tablet started to reboot again. Interestingly the battery now showed only 2% and the low battery warning appeared.
I think the problem might occur only when the battery runs low (which happens very fast as something seems to drain the battery), while android still shows a much higher battery level . Never experienced these problems when the tablet was plugged in so far.

At least I don't feel so alone with this issue... I have been paying more attention to my build up process since the factory reset. I found, the other night quite by accident, that when I logged in to Twitter the reboot started. So for the next few days I have left Twitter off the machine and it is doing better. I suspect that something is hitting the power drain (like you mention) and that causes it to have problems. In that thought I have also turned off the power saving mode and auto screen now just to add to the list of things I am avoiding.

Have you considered rooting and using root apps to stop the apps from being able to do such things?

My M8 turns off by itself & afterwards settings etc are reset!

I'm experiencing a weird problem with my M8. The unit would turn itself off all of a sudden. This happens without a low battery warning and no other error messages or warning displayed on screen. No beeps or audio cues, either. I would be looking at it and using it as per normal when it would just power down and turn off all by itself. This has happened twice in the last two weeks. In both instances, they have these in common:
a) Battery was low but not critically so. IIRC, the first time it happened the battery was at 25% and the latest incidence the battery was at 18%. The low battery warning usually given at 15% power wasn't displayed.
b) In both cases, I've just only turned the display on & started using the M8 for less than 15 seconds before it turns off.
c) In both instances, the mobile data & GPS was on. Wifi was off. Phone wasn't charging and the camera/flash was also off.
What I do after this happens is I would go home & charge the phone using the original M8 charger. The charging battery icon would be displayed and the charging level tallies with the last charge level that I see before the phone turns off. I let the phone charge for about 10 minutes or so before tinkering with it.
What's frustrating is that after these sudden shutdowns, some of my settings were reset & the phone will be wonky. I had to re-do the settings in both the settings app & also Google settings according to my preferences. Some default apps were cleared as well, so the phone would ask which app I'd like to use for my Home screen (either Sense Home or Nova Launcher, which I use exclusively). Some developer options were reset too, e.g animation scale etc. Other basic settings as well, such as auto updating apps in Google Play Store.
Also, first time it happened, I was locked out of my phone. The lock screen is displayed but all the PIN combinations I've tried seems to be wrong. The lock screen would go off after I try inputting the PIN. Restart by pressing vol button with power button didn't work at all. I'd touch the screen, the lock screen will be displayed, I'd try inputting PIN but I guess it's wrong because the screen just goes off. In the end, I had to reset the PIN number using Android Device Manager on Chrome running on my desktop PC. Only then was I able to access my phone. My wallpaper was reset, although my app icons on the desktop was the same as before. Apps were all there.
The 2nd time this happened was yesterday. I wasn't locked out of my phone but all my text messages (SMS) were lost. No other loss of data, as far as I can tell. But some of the settings, default app preferences & also app permissions were reset. Had to redo them all over again. Getting a bit tiring, this.
I don't understand what's happening. My M8 is on 6.0, stock ROM & unrooted. Never rooted. I've done the battery calibration steps once but that was before the Marshmallow update. When my M8 was running Lollipop, there were times when it would turn itself off as well but it was triggered by using the camera flash at low battery levels. However, settings, app preferences & permissions were not reset at all then.
Has this happened to anyone? What could be wrong? Would appreciate any & all feedback Thanks in advance.

This happens to me too. My battery is dodgy and it turns itself off when the battery is displaying anywhere up to 30%!! What I have found is that if you attempt to turn the phone on and it turns back off during the boot process then this is what screws up the settings. As long as it is charging and completes the boot without turning off then the settings are fine.

This is a MM problem. Wasn't present with LP as you and others have reported.
The only possible fixes on your end is to do a factory reset and then run the phone down until it shuts off and then charge to 100% with the phone still off. You can also try holding power+vol up+vol down for 2 minutes. This should wipe battery calibration stats. These suggestions may or may not resolve the problem but are worth trying.

Its happening to me!
I thought this was MM issue but i have flashed cm 14.1 and still the same problem is happening. My phone turns of somewhere between 15%-30% everytime. I have tried re-calibrating the battery but it didn't help. Now i am thinking to sell the device due to this issue.

My girlfriend had the same problem with her HTC one M8.
I've replaced the memorycard with a new one last week and it didn't happen since. Hopefully this will solve the problem

Hi together.
I want to give an information about my experience with sudden shut off. I had this issue with my M8 since about six months now. Tried the stuff with recalibrating the accu without success.
Last thing I did was changing the accu. And now everything is all right. The power is remaining much longer over the daily use and I can bring it down below 15% without sudden death.

Note 10+ warm to the touch

I've had my Note 10+ since launch and it's been amazing. Recently the phone has been getting warm, nothing unbearable though. I have tried various things such as booting into safe mode to see if there any rouge apps. I have also tried wipe cache partition but it still exhibits the same warm feeling. Never had this issue before. My last resort will be doing a factory reset. If anyone can give me ideas that would be great.

Best thing to do would prob be send it to samsung or your network

I was thinking about doing that, but that would be my last resort after a factory reset

Any other suggestions?

That's all I could think of sorry

If you use Android Auto it will turn the screen on when it connects through Bluetooth. If you have it plugged in it isn't a problem but if you are in the Car when it connects to the Bluetooth it will automatically activate and the screen will stay on even in your Pocket. You have to manually exit it if it starts and you don't want it to.

OP does not report battery states when phone getting hot (does battery discharges fast?). Also not clear in what state phone gets hot (in use, while charging, in idle state?).
Getting warm relates to use of energy => battery fast discharging or battery fast charging.
Check if there are apps using a lot of power, maybe even in background, they may be the cause. Remove or limit use of those apps.
If no apps are producing the heat, then it could be hardware issue: return phone checked by Samsung or service centre.
Upgrade to Android 10 may be good moment to do factory reset, and see from there...
