Huawei’s latest flagship – the P9 – comes with a 5.2″ IPS 1080p display and is powered by a newer Kirin 955 chip with an octa-core processor, efficient Mali-T880 MP4 GPU and 3GB of RAM. It has a sealed 3,000 mAh battery. The supplied charger is a regular 5V/2A, but that’s still enough to fill about 35% of the battery in half an hour.

The phone runs on Android Marshmallow with the latest Emotion 4.1 launcher. Huawei promises an energy-efficient chipset and software package. Indeed, we found lots of battery optimization options in the new Emotion UI, which you can enable and will save you battery by limiting background app usage, processor performance, and more – depending on your needs.

Of course, we do our battery test without those battery optimizations to calculate the raw power of the device. We set the screen to 200 nits and begun our routine. In case you’ve missed in our review, the Warm color option for the screen turned out to be more accurate than the Normal one.

Our first test gauges the 3G talk time, and the P9 did very well lasting almost 15 hours.

We were a bit disappointed with the video playback endurance at about 8 hours and 45 minutes. This is more than sufficient for a long flight, but we expected a bit more with this battery, screen, and chipset.

Standby battery life was gauged in the Performance mode, which does not put any limits on the hardware. The Standard mode will add a couple of hours to the rating while the Ultra Power Saving will keep your phone alive for quite some time. Even without any optimizations, Huawei P9 proved to be power-efficient when left on standby.

Overall, the Huawei P9 scored a 75h rating, which means you can count on the battery to last just a few hours north of 3 days if you do an hour each of calling, browsing the web and video playback a day. Such usage pattern may be somewhat artificial, but we’ve established it, so our battery results are comparable across devices.

Huawei P9 review

There is also the so-called ROG power-saving, which lowers the native resolution down to 720p and will give you more battery life when playing games.

The battery testing procedure is described in detail in case you’re interested in the nitty-gritties. You can also check out our complete battery test table, where you can see how all of the smartphones we’ve tested will compare under your own typical use.
