If you tried to access this page last night, from around 21:00 CET to around 9-10:00 CET today, chances where that you didn’t get to the page at all.
This isn’t something new, seen it around pretty much any android/sense update since I started doing this. This is just a starting point to finding how to fix it.
This I tend to see a LOT of. It’s rarely the battery itself that’s faulty.
Tends to see this as lot around large updates, like now with 4.2.2/sense 5 for one x/x+. Have written about this before, but will try to cover a bit more this time.
Of course: can be a serious problem often it’s “just” that you need a factory reset to sort it out. It’s rarely something big and complex that causes it.
