Just another update, my powerbank doesn't charge my phone in AC mode any more which is disappointing. It only charges in USB mode.
Can someone help me I'm confused. Are these type of products battery chargers, external batteries, or both? I was looking for one today and because of the description I couldn't figure it out. I'm looking for something to plug my phone into while it is fully charged and have that thing deplete its battery before my battery is touched. Does that make sense?
Obviously.. it does
I got a SGSII (1650mah under 3.7V), without going into details and discussions about mine does more.. blablabla, as an example :
- Screen on the battery is depleted in 4.5 Hours => Current drawn is high => Charging phone screen on... is baaaadd (if you do not needs it on, keep it off)
- Pure 2G standby i got more than 3days => Current drawn is very low => Charging phone when off or when on standby (screen of) will make near no differences

I suppose that it will works this way but constantly charging your device (phone in your case) is not very good for the durability of its battery. Never keeping a computer battery in a computer that is constantly connected to the power outlet... it will ruin your battery in a year.
Some nice computer have a special battery, throught a specific software i can "program" the battery to stop charging at 50%, 60% .. the info is ketp in the battery, putting it in an other computer and it will never goes higher than the choosen percentage. (My Vaio got this very usefull functionnality).
