Re: Why my HTC one s gets warm for no reason and drains out the full battery in 1H!
Hi, I've got the
exact same thing since week or two on my HTC One S. I'm suspecting a rogue app but no clue which one and don't know how to find out; a CPU monitor seems to indicate the CPU is at 100% all the time. Uninstalling some apps didn't work, updating apps (after removing some first because of memory) didn't work either. I'm guessing it's some Google/Android process :-\
It seems to drain faster when on cell instead of WiFi, and gets quite hot indeed, but maybe that's because of constant mucho network traffic.
Google Play seems to act weird; it doesn't show my apps any more, but does show all and other page; it downloads updates to ~70% but when I then close and restart Google Play it does update the fully downloaded app, weird. Also, when I go so the Sync settings, Google syncing seems to act weird, always busy syncing something and trouble syncing calendar, Keep and I believe contacts, could be a clue, there's a message at the bottom "syncing is not working at the moment, it will be back shortly!" (what can I do about it?).
Internet is fine and fast on cell and WiFi so don't think it's a signal problem. I'm considering a factory reset, or perhaps a remove/add account first, but want to do a proper backup first (connecting to Windows and Linux doesn't show any folders on the phone :'( ). Frankly I don't want to start from scratch...afraid to lose stuff....it was all working fine...
It's almost as if they've flipped some switch to force us to a new phone... :-$ The problem with the HTC phones is that they're too good in my opinion

I keep extending them because they're still fine (
small, fast enough, battery life is fine, good screen). The only thing I would like is a HTC One S2 with 4G and more memory and some updated Android/camera perhaps...that's it but HTC doesn't seem to understand. Options for me are now: HTC A9 (not out yet, bigger and weird spec difference with the US), LG Nexus 5X (not out yet, not sure if stock Google will be a big difference, bigger and why no SD card? or FM radio anymore?), HTC M8s maybe (no Marshmellow?), guy in shop recommended Sony Z5 Compact perhaps. Reviews seem to chop down almost all phones these days, I don't know what to buy anymore.
