Charging iphone 4s battery removed from phone.

[rfisher]

Anyone know if you can charge the battery in an iphone 4s when it is removed from the phone?

Replaced the battery in son's iphone with a new one but the phone won't boot.

I'd like to charge the new battery fully and then put it in the phone, in case there is some sort of shutdown protection thing going on with the logicboard due to the previous battery getting fully discharged.

Don't think new lipol batteries are shipped with much charge in these days, due to potential fire risk when they are fully charged up.

Ta.

OK thanks.

So you pulled back the tape at the bottom of the battery and connected directly to the battery terminals where they are soldered to the charging control board?

How long did you leave the PP3 connected?
