HTC One (M8) battery life test: excellent endurance


Believe it or not, the new HTC One (M8), with its 2600 mAh battery, tops the mighty LG G2 marathon runner, and its 3000 mAh unit, in our battery test. As you can see below, the One (M8) lasted 7 hours and 12 minutes of screen-on time in our grueling test load, while the G2 scored 6 hours and 48 minutes.

In fact, crossing the 7-hour mark on our battery test typically signifies entering the phablet endurance realm, as those big-screen handsets usually have place inside for much larger than the average batteries. We can only say kudos to HTC for this spectacular achievement, which is bringing us a 5-inch handset that is only outlasted by giant phablets like the HTC One max, or the Oppo N1. The HTC One (M8) also flaunts an extreme power-saving mode, that lets it last about 30 hours on standby, even with 10% battery capacity left.

Its 2600 mAh unit is of the lithium-polymer variety, and is only 13% larger than the 2300 mAh juicer of last year's HTC One, yet brings in a whopping improvement in battery life, as the old One scores 5 hours and 45 minutes on our test. Needless to say, we can't wait to pit the HTC One (M8) against the other two spring chickens - Samsung's Galaxy S5 and the Sony Xperia Z2 - as those two also promise enhanced endurance, and dedicated power saving modes.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.
