HTC One S battery life testing is complete, here’s how power-efficient the two Krait cores are


We wanted to publish the HTC One S review as soon as possible so we had to do without the battery test (which takes a lot of time to complete). It’s done now and we’re ready to share it with you – especially since HTC doesn’t quote official numbers for the One S battery life.
We were very curious to see how the new chipset, part of the Snapdragon S4 family, performs compared to the old S3 models. It’s built on a 28nm process, which should offer much better power-efficiency than the 45nm process of the S3 chipsets.
On a 3G call, the HTC One S did really good – it lasted 9 hours and 42 minutes, which is very impressive considering the phone’s battery has only 1650mAh capacity. With the exception of the Samsung Wave III, the One S was beaten only by gadgets with huge batteries (the Galaxy Note has a 2500mAh battery, while the RAZR MAXX packs a whopping 3300mAh battery).

The HTC One S has an AMOLED screen, which is usually bad news for web browsing. The One S lasted 4:03 hours, which is roughly comparable to most other AMOLED phones like the Galaxy S II or the Lumia 800. The exception to the rule is the RAZR MAXX, which offers almost twice the endurance of the One S (but the MAXX battery is twice the size of the One S battery).

The One S redeems itself in the video playback test – at 9 hours and 28 minutes, it ranked in our all time Top 3. We are not saying you should do it, but this would allow you to watch the whole Lord of the Rings trilogy (Wikipedia claims 9 hours 17 minutes of runtime) on a single charge.

The endurance rating for the HTC One S works out to 35 hours. That means you have about a day and a half before you’ll need to recharge it, assuming you talk for one hour, browse the web for another hour and watch an hour of video each day.
The rating doesn’t seem impressive, but that’s due to the relatively poor performance of the One S when it comes to web browsing. If talking and watching movies is all you do, it will last a good deal longer than a day and a half.
