I got the idea after this thread: CLICK where the poster asked if leaving you're phone plugged in for extended periods, or if charging it every night would hurt..so here are some FAQ's about Li-On batteries!
Will it hurt my phone or battery in any way if i charge it to much?
It won't hurt the battery to leave it plugged in. But you should unplug the Dare before you place calls.
If it says Charge complete does it have to be un plugged immediately?
Leaving it plugged in is NOT bad for the battery. Modern chargers and batteries have sensors which "turn off" the charger once the battery is fully charged.
Should I let my battery go completely dead every so often to extend it's life?
Another myth. Modern lithium-ion batteries do not need to be drained completely. In fact, doing so is actually bad for lithium-ion batteries.
Is there a faster charger for my battery?
No. Manufacturers of lithium-ion cells have very strict guidelines in charge procedures and the pack should be charged as per the manufacturers "typical" charge technique.
Do I need to charge my battery for X amount of hours when I first get it?
No. Lithium-ion is a very clean system and does not need priming as nickel-based batteries do. The 1st charge is no different to the 5th or the 50th charge.
