I leave mine in the dock all night. I hope it's not gonna be an issue.

 

It doesn't "charge" overnight. Your home charger is a smart charger. You can tell because at 100% charge, the white LED turns off. At that point, it's either trickling or doing nothing. You're fine. You should try to avoid deep recharges, i.e. where the battery is nearly fully discharged and then recharged to 100%.

 

Yes, I leave it plugged in all night. It doesn't harm the phone.

 

Leaving your phone connected to the charger for long periods WILL NOT HARM YOUR BATTERY.

Lithium based batteries do not suffer any ill affects from remaining connected to a charger for long periods of time, nor do they suffer ill affects if you 'top them off' by plugging in after short periods of use.

Lithium batteries DO suffer ill affects if you discharge them deeply and leave them discharged for long periods.

 

Actually that shouldn't be a problem. Just don't leave it discharged for long periods, and avoid draining it deeply if possible.

It's actually a good idea to wear down the battery pretty far (15% or so, until you get the warning) from time to time, then charge it up completely. Every month or two should be good.


Lithium batteries can be thought of kinda like muscles - they need some exercise to stay strong, although they do not suffer 'memory' like nickel based batteries. They will also atrophy if they are left discharged too long.
