After a year + of problem free use I woke this morning to find my desire was on (and battery nearly drained as a result):
I click the off switch and the screen blanks and appears to go to sleep as normal but a split second later it turns back on again.
If I leave it the sleep timer kicks in as normal and the screen blanks but a split second later it turns back on again.
Same behavior whether on charger or battery.
Removed sim and sd card - same behavior.
Cleaned contacts and re-inserted - same.
Full hard reset - everything cleared - same.
Wifi on or off makes no difference.
Once in a while it will stay off and I think the problems solved itself but ten minutes later I check and it's turned itself on again.
Warranty expired last week of course.
Any ideas?
Thanks, M
I've got an issue with my 7, every time I set the sleep time (Settings -> Display -> Sleep) to something other than 15 seconds, it keeps resetting itself back to 15 seconds. It seems to occur every time the device screen is turned off or a timeout occurs. I'm on 4.4.4, stock, unrooted. There's no apps I can figure are causing this issue. I've tried removing it from the case, no help. It's basically making the thing unusable.
It seems to be the same issue here, though not exactly, as mine occurs immediately, not after several hours or charging:

Any suggestions? It's kind of driving me crazy.
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.
Hi, Im running OxygenOS 3.2.6 and my phone goes to sleep mode way too fast like within 5 seconds sometimes.
At first it wouldn't go to sleep, so I rebooted and now this problem is occuring. I have set it to 15 seconds in the display settings. What seems to be the issue?
Thanks
Curious if others have this happening and if they determined what the culprit was. Within the past week or so the setting for display/advance/sleep had been resetting itself. I will set it for 2min or 10 and after a few hours the screen goes to sleep under 30 seconds. When I go back to that settings page none of the options are ticked and I have to reselect the one I want. Haven't installed any apps in a while at least long before this started. Could be an update that happened to one of the apps so I'm going to try safe mode. I'm stock rooted with elemental x kernel.
Edit: Using safe mode stopped issue, and after two weeks of disabling apps that I think was the issue I finally figured out which one.
To the mods, this is a Tasker issue. You can delete this post as I will now pursue this on Tasker's forum.
