Hi, I have some useful info that helps increase N900 battery life more than twice

As is the case with many users, the USB port came out along with charger cable on one fine day. And, the Nokia care center in India is asking for Rs 9000/- to fix it where as a new phone is available at 14000/- as on today.

To continue using this phone, I have got 2 additional original batteries and an external charger (China made) available @ just Rs 100/-. The idea is to carry additional battery along with me and replace it as and when the battery gets discharged completely.

You know what. Shocking me, with the battery that is charged externally, it is lasting for more than 50 hours without any difference in my usage. Earlier it used to last a maximum of 24 hours (where I tend to use the phone sparingly to ensure that it lasts until I reach home).

I am not sure about where am I getting this additional charge from. The batteries are same and the usage is a bit aggressive now (as I am now holding a spare battery ). Those people who are struggling with battery life can give it a try.
