HTC One battery scores very well in endurance tests

If you have been worried about the sealed battery into the HTC One, fret not, as it seems to power the phone for a long time, an improvised 3rd party test indicates.

The One sports a 2300 mAh juicer, with which the phone managed the very respectable 8 hours and 32 minutes of video playback, and more than 16 hours of talk time in 3G mode. Given that any score above six hours in continuous video playback is already above the average mark, this is a pretty good achievement on HTC's part, and with a high-res Full HD screen at that.
