I've been batter testing. I haven't charged my phone for two days. I have at this moment 20% battery left.
The things I do with my phone. I use the things below on a regular basis, plus I have quite a few widgets.
- Read books (52% of the battery went to screen)
- Text/Check personal email
- Search the internet (while at work)
- FourSquare
- Google Maps
- Weather updates
- Google Play music, on the way to/from work.
- Play a few games
- Snap Pictures/Upload
If this was my EVO 4G I wouldn't be able to go 10 hours with doing all this unless I plugged into the usb port at work.
I'm very happy with battery life and I think it's a non factor for anyone saying they would not buy this device, "because it does not have a removable battery".
There are plenty of ways around that issue. Just plug it into a usb charger on your PC at work or in your car.
