Work Performance – PCMark

We tested the ZenFone 3’s performance using PCMark, which simulates work applications like web browing, playing video, writing text and editing photos.

Work Performance Score

Web Browsing 8045 6257 5782 8073
Video Playback 3469 4287 3321 4396
Writing 7316 7166 7463 6231
Photo Editing 8246 8262 9694 7352

The Qualcomm Snapdragon 625 processor powering the ZenFone 3 (Amazon) did very well in this test, besting the ZenFone 3 Ultra (Snapdragon 652), the HTC 10 (Snapdragon 820) and the honor 8 (Kirin 950).


Battery Life – PCMark

We then tested the ZenFone 3’s battery performance using PCMark. It basically ran the PCMark work tests until its battery capacity dropped to 20%.

The ASUS ZenFone 3 (Amazon) only comes with a 3,000 mAh battery, but it lasted almost 12 hours in this test! This is 22 minutes longer than the battery life of its big brother, the ZenFone 3 Ultra, which boasts a 53% larger 4,600 mAh battery. This is excellent battery life.


Battery Recharging Performance

The ASUS ZenFone 3 comes with a 10 W fast charger. Take a look at how fast it recharges the 3,000 mAh battery.

It took us 99 minutes (1 hour 39 minutes) to recharge the ZenFone 3 (Amazon) from 19% to 100%. That’s a battery life : recharging ratio of 7:1 – very impressive!

As the charger does not support any fancy fast charging technologies like Qualcomm Quick Charge 3.0, the charging profile is a relatively flat curve. It showed slightly faster charging up to the 70% charge level, before tapering off a little.
