Once you stop thinking about this phone, it performs exceptionally well.
In the past two days I've been too busy to think about battery life.
You can easily get 3 hours of screen time out of 20+ hours of use.
4-5 hours of on screen time with about 15-16 hours of use.
What do I mostly use this phone for?
- IM Messages
- SMS messages
- Emails, work and personal ( I have a total of 3 Gmail accounts synced - 2 G Apps one standard)
- 40 minutes or so of streaming Google All Music Access on the daily commute (LTE + Bluetooth)
- Some occasional mobile GAF browsing and Feedly reading.
- Very little phone calls.
I think constantly pushing the phone to see how long it can last gives it a wrong impression on how you actually use it day to day.
