When to know it's time to replace the Nexus One battery? As we all know, battery consumption rate (i.e. "per hour") is not very standardized and its highly dependent on actual use, per user.

This makes it very difficult for me to know whether I need a new battery for my Nexus One (I bought it used) or not.

Assuming WiFi and Bluetooth are enabled, how long should the Nexus One battery last while the Nexus One is in Standby?

How long should the battery last when the Nexus One is completely turned off?

Thanks.
It is very difficult to put a number on the estimated battery life of the N1, mainly because there isn't really a standard "typical use".

But since it seems that you are looking for a number, this thread may help.

Since at least 2 people reported at least 2 days in a single charge (given certain conditions), I would say that if your N1 battery doesn't hold more than 10 hours, it is time to start shopping for a new battery.
