Thank you for contacting HTC!
We do apologize for any issues you are having with your HTC Google Nexus One. However, from what you have told me about what is running on your phone, 5 hours after a full charge to be at 50% is not bad. The WiFi and GPS alone drain your battery quickly, so we recommend that they only be on when you need them. I hope this solves your issue.
Sincerely,

Inquiry Description Hello, Wondering if I possibly have a defective battery in my Nexus One. Purchased on 1/7/10. After about 5hrs (from a full overnight charge), battery % is down near 50% or less. This is happening daily. Usage is maybe 15min of calls by this point. Screen brightness set to about 25%. Bluetooth off. WiFi on. GPS on. Email, web, sms... nothing outrageous. Apps with notifications are Weather Channel app, Facebook, the default news/weather app... and that's about it. No IM apps running. What do you suggest? Is it possible to obtain a replacement battery, and send in my current one?
