Can i leave my charger in my phone/laptop even though it's been fully charged?

yes you can but only for a short while other wise you battery will lose some of its life

for macs you can leave it in and work on it for 2 hours after it's fully charged and then you should pull the charger out

for your phone you should take it out immediately because when it's fully charged it will say "remove to save energy" (I also have an LG secret)

Lithium based batteries (used in most modern electronic devices like mobile phones, laptops, PDAs and just about everything) have a protection circuit, built into the battery iteslf, that disconnects the battery when the voltage reaches a certain level.

So check if the battery is lithium based.

The other advantage of lithium batteries, is they have no "memory effect" you can charge them repeatedly, without needing to drain them to empty before charging.

Yes. Once the battery is charged, the charger provides all the power and stops charging the battery.

Yes - these days most rechargers are 'intelligent' meaning they adjust according to the charge in the battery. This is not always the case for cheap items, but you can feel safe with laptops and phones as they're big-ticket, highly mass produced items :)

Yes, it will effect the battery life, but not to any high level.

If you download iTattle, it will tell you how much charge your computer battery will hold, how much it has left, and how much it has done before.

Don't worry so much. I almost always have my computer plugged in and mine is an iBook Late '04, so it's worse quality than yours.

Good luck!

yep just leave it in when its fully charged the phone and computer take power from the wall or car only the battery is no longer charged or used

Yes

i never unplug my laptop and i let my phone charge all night and both work super well :D

so yes it's okay, i dont know anyone who doesn t leave their laptop plugged in all day

I wudnt b/c eventually it will start makeing the life of the battery shorter. i dont kno why but it will,. it happened to me.

yes, because sooner or later it's gonna stop charging on its own.

so it really doesnt hurt anything
