HTC One battery tests deliver the best web browsing endurance

Due to the pretty pretty aluminum unibody of the HTC One we were willing to overlook the fact that its battery is sealed tight, as long as the 2300 mAh unit provides decent talk, browsing and video playback times.

Now a 3rd party battery test confirms other 3rd party tests of the phone's endurance, as well as our own real-time observations about the handset's stamina while using it for reviews and comparisons.

In fact, at close to 10 hours, the phone scored the most out of them all in web browsing endurance, including the reigning champs RAZR MAXX and iPhone 5. It also is up there in the top with more than 10 hours of video playback duration, alongside proven marathon runners like the S4 and III, as well as the iPhone 5 and the obligatory RAZR MAXX. 

Talk times were also close to those delivered by the S 4, at more than 13 hours, and about the only thing hindering the HTC One's final score is the standby time - it appears there is some leakage during standby, which draws the battery faster than it should. These are usually fixed with a firmware update, though, adfer the company identifies the rogue chip or app that causes the unnecessary battery drain, so when this happens, we might be looking at one of the best battery lives on a smartphone, delivered in the slender package of the HTC One.

Our first battery test is all about 3G calls. The HTC One battery went out after 13 hours and 38 minutes, quite an impressive result and very close to the Galaxy S4′s talk time despite the 300 mAh battery advantage of the Samsung flagship.

Talk time

• Motorola RAZR MAXX (ICS)21:18
• Google Nexus 414:17
• Samsung Galaxy S413:53
• HTC One13:38
• HTC One X+13:31
• Samsung Galaxy Grand Duos12:45
• Pantech Burst4:46

HTC One did an amazing job with the web browsing test. It outlasted every other smartphone we’ve tested so far and took the first place in the chart coming just a couple of minutes short of the 10 hours milestone. Nicely done, HTC.

Web browsing

• HTC One9:58
• Apple iPhone 59:56
• Motorola RAZR MAXX (ICS)9:12
• Samsung Galaxy Nexus3:01

Finally we’ve put the One into an endless video playback loop to see how long it’ll take for it to lose 90% of its battery charge. We were in for yet another impressive result with the HTC One matching the Samsung Galaxy S4 and the Apple iPhone 5. The battery drained after 10 hours and 2 minutes, which is quite an impressive result sufficing for sixth place in our all-time chart.

Video playback

• Motorola RAZR MAXX (ICS)16:35
• Samsung Galaxy S410:16
• Apple iPhone 510:12
• HTC One10:02
• Samsung I9300 Galaxy S III10:01
• Samsung Galaxy Express10:00
• Nokia Lumia 7103:27

With the kind of performance we witnessed in the indivudual tests, we were preparing to see the HTC One post a record overall score. Alas, the smartphone was led down by its standby efficiency and only manged 48h. That’s as much as the Sony Xperia Z, but seriously short of the Samsung Galaxy S4 achievement. This means you’ll only need to charge the HTC One every 48 hours if you use it for an hour of talk-time, an hour of web browsing and an hour of video-watching per day.
