For years, consumers have been a little worried about smartphones with sealed battery. The HTC One is one of them, but fret not as it is proven that the flagship can stay operational for a long time with a single charge. The HTC One boasts a 2,300mAh battery under its back cover and it manages to deliver about 8 hours and 30 minutes of battery life when running video continuously.
The phone can even last for more than 16 hours when used for voice calls in 3G mode. In current smartphone industry, anything above 6 hours of battery life is already considered as above storage. This is an impressive achievement considering that the phone comes with a powerful processor and 1080p display.
As a comparison, the Sony Xperia Z is only capable of delivering only five and half hours of continuous video playback.
