I've always been a little obsessive about not leaving my stuff on charge when it's on full, but always charged to full, typically, I'd just assumed modern batteries can handle it!

Maybe some can - my ipad is pretty good at holding a charge still and it's more than 3 years old. Not so my phone, and that's only six months old!

yeah some devices take care of it for you.. it depends how often you cycle it.. ipads tend to go for DAYS where as the phone is always one day.. so that can be a 5x or more cycles.. im real careful with my phone.. its already getting bad.. especially with the heat.. the thing almost dies in the car when the sun is out..
