Which type of bug at there?

IU bugs, sometimes in settings, the UI become crazy.

When you say that, yeah i noticed that too.
So the best solution?
On another note, just clocked 2 hours & 15 minutes of charging from complete 0% to 100% using powerbank.
I used a stopwatch to measure time.
Compared to charging if turned on, it took more than 3 hours to charge from 0% to 100%.
1 hour difference wooo

No solution, let it charge till 100%, plug off.

a little read about modern battery and the charging system, and why leaving overnight charging is not bringing damages:
http://phandroid.com/2010/12/25/your-smart...ch-a-bad-thing/Even if there's no memory effect, it'll reduce the cycle life of the battery, although less, and I believe the trickle charges will put stress on the battery and produce more heat.
and according to
LifehackerQUOTE
Don't leave it fully charged. Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. When possible, keep it in that range to prolong its life as long as you can. And, if you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health.
I believe from your source, partial charges in a scenario would be charging when the battery charge is at 50% or more left.
