None of them. OEM only. The charging circuit is built into the phone - and its meant to charge a certain capacity. It also has a "microchip" on board to communicate status back to the phone. You will get an "Invalid Charger" or "Invalid Battery" message - and it will fail to charge.

We offer special chargers, that will charger a li-ion battery, that is much higher capacity than the OEM one. The smarts are built into our charger.

Hope that helps.

Hmm.. that's no good then. What sort of battery besides the OEM ones can be charged by the phone?

Sure you can; but you will need a whole new charger to use with them also - and if your only using 1 at a time you will be good - if your going to use more, you will need to match the cells and charge as a unit.

Would it be safe to wire in one of these batteries to a i4XX?

Keep in mind this is one with the battery protection circuit wired into the battery.

Also, I'm aware of the battery-saving motion sensing circuits, I just want as many options as possible.

Thanks,
