I have the DNA, and the battery life is much bettery than reported, for what its worth. Pulled my DNA off the charger at 99% at night. Next morning, checked email, Twitter, read some news sites. Then, I turned on my Bluetooth headset and went to work. Headset was connected all day. I made phone calls, listened to Google Play music for a couple of hours, used Google Maps, read email and Gmail, did some Twitter stuff, took a few photos….After 16 1/2 hours, all of which was 4G connected, my battery was at 12%.
I wonder whether, when Apple finally adds wireless charging, it won’t ignore both current methods and create some entirely new approach. Then we can get even more fragmentation and no charge stations in public places any time soon.
