Hi, skccs32, I am also shocked to know your battery problems. One thing many people might have missed is the battery drains caused by instability of 3G/GSM mobile network switching.

My mobile plan allows my phone to switch between 3G/GSM AND other mobile carriers. It means to improve the availability of network, but I found that if I am located in the particuler area where two networks overlapped, the battery drains very quickly.

The cost of network swithing seems to be very high, so I fixed the mobile carrier in the setting, and the battery no longer drains as before.

Anyway, YMMV. Hope this help and may Lord blesses you, your daughter and your N900
