It looks like HTC's claims of dramatically improved battery efficiency for their all new HTC One M8 aren't just wild boasts. In fact, the new HTC One M8 was taken to task in a battery life test, yet it dominated all current competitors, including the venerable Motorola RAZR MAXX and the impressive LG G2. As you can see, it also bested the Samsung Galaxy Note 3 phablet!
Despite only having a 2,600 mAh battery, the HTC One M8 scored higher than any other competitor on the list, with 7 hour and 12 min run on a "custom web-script, designed to replicate the power consumption of typical real-life usage." Whatever software improvements HTC included are really doing amazing work under the hood. Of course, the folks who performed this test didn't have the new Sony Xperia Z2, nor the Samsung Galaxy S5 to test. It will be interesting to see how these other next-generation devices fair against the new reigning king of battery efficiency.
Kudos are well deserved to HTC for the dramatic battery improvement of the HTC One M8!
