I gave mine an initial charge of 8 hours (force of habit for all new gadgets). You could probably go for less, but I like to err on the side of caution.

Even though the battery reports 100%, it's not actually full and when it does reach 100%, it just stops charging so there's no risk of overcharge at all.

Hope that makes sense and welcome to the forums!

 

Good stuff, let us know if you have any problems.

 

I also did a full 8 hour charge while it was turned off and have had pretty good battery usage. I am managing to get 2 whole days out of the battery between charges.

 

whats the ideal thing to do when you need to charge the phone, let it run until you get the connect charger message ? or is it safe to do top up charging ?

the reason i ask if you wanted to go out and your phone only had 20% but you wanted to give it a quick blast to last you for when your out, is this not recommended ? seems pointless to me as you don't want to be without a phone when your out just because its not recommended to do a top up charge

whats everyone's opinion ?

 

For the initial charge I give it a full 8 hours or so, then let it discharge completely. You can do that for the next 3-4 charges, but I don't think it's mandatory. After that, charge as and when you like.

The manual for my Transformer says that if you run the battery flat/nearly flat, to charge to 100%, but other than that, I don't think it matters.

tl;dr version: a top up when your phone is at 20% is fine.

 

The Li-Ion Battery Does not need an extended first charge, thereafter it is recommended to do a few cycles, then it can be charged as and when needed!
