I just ordered 3pcs 1100mAh backup batteries for n900. Now I started thinking ways to have longest possible continous battery life.
- power over usb to keep device running when switching batteries(experts opinion needed)
- hardmod one battery with connectors continously plugged in and glue it into cover(probably too extreme but doable)
- other way to feed power to keep the device alive during battery switch
- tweaking os for hibernation?!?!

How about building an external power-pack from the two spare batteries, with a USB cable to attach to the device. Of course you are still left with the problem of charging the power-pack. I've used a PowerMonkey with my N800, but I might need to get a new adaptor for the N900 when it arrives.

OK... Maybe I'm just thinking in the box... but why not just an EXTENDED battery. Or: I have a mini/micro usb charger that's 1700 mah, and I keep it in my bag. OR: I liked the first option. Run the device on USB while switching out the battery and replacing it. That's my fav.

All those batteries will make a non-negligible mass to carry...(edit: I approve the continuous supply from the USB port)

i know next to nothing about electricity, but would this be possible: having thin wires connected to the surface where the battery connects to the device - to those wires could a second battery be connected (even if only by holding it together) for the short while the almost dead battery gets removed and a third battery gets inserted. alternatively one could try to slide the second battery in place and then quickly remove the wires.

Of course driving battery to the limit and wait until device dies and then switching batteries is an option. but why not consult the community about it. hope we come up with different ideas.
any suggestions?
