Granted, I didn't experience this alot - twice to be exact. But while charging tonight, the padfone had turned itself off. It happens the day after my exam (luckily as i use it to wake me up).. Anyone else experienced or resolved this? Kinda need the reliability.
I had one unexpected re-boot about half an hour after the JB update came through, but no unexpected power-downs or re-boots before or after that. I can only attribute my one-off problem to the fact that the update was still "settling."

The exact same happened to my pf2 also. (At night while phone was charging). It also didn't power on as usually. I had to keep the power button down much longer. After that I haven't experienced similiar problems.
It seem to be doing it my padfone 2 also. It seems that when you have lots of apps running consuming significant amount of RAM, then it restarts by itself. There is a default widget called tasks where you can see what apps are running. Get it on one of your home screen and when the running apps count more than 13 or 14, then you have to tap close all. You can also lock which tasks you want to it be running for e.g music player..
Also get an app called cache cleaner. Keep cleaning cache every night or something..
These are what I'm trying and its kind of working.
I wont be forced to do that in a 2gb RAM phone. Obviously, im already using the widget to close programs when I have had alot running (of my own choice). Luckily it's only happened twice (the reboot). However the biggest issue is, sometimes the battery works just fine (charges to 100%) --> Today i wake up after 8 hours of charging and its only on 30%.. That battery is so fucked, but everytime im close to returning it, it charges to 100% (like it can hear what i say)
I also have the problem that the phone powers off after a few hours for no reason. I tried with those cleaning apps but the problem presists. Too bad since i wanted to use it as alarm clock :/
I always have 20-25 apps running (according to the widget) and don't have any problems. The only time I click the "close all" button on the widget is if I look at it and think "why is this app still running?" And that only happens once a week.
As with all potentially software-related issues, I'd suggest doing a full factory reset and cache wipe, especially if you haven't done this after the initial JB update. This will remove any possibility of "faulty" data/settings being the cause.
If this doesn't resolve the issue, then it'll definitely be a hardware problem - either overheating CPU or RAM, or faulty joints/components on the mainboard - so replacement is the only solution.
