Huawei P9 battery life

gearbest.com

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.

The web browsing time is OK – 9 hours of straight web browsing should be enough for most of the people.

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.

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.

  1. I am still using the galaxy s4 and i will not buy another smartphone until they improve battery technology that lasts at least a week with heavy usage i think that’s what most people would like to see in the smartphone world

  2. Anonymous, 11 hours agoI am still using the galaxy s4 and i will not buy another smartphone until they improve batter… moreWell then you will be waiting for a long time. So long that all your money will be wasted on replacement batteries for your precious S4.

  3. Anonymous, 11 hours agoI am still using the galaxy s4 and i will not buy another smartphone until they improve batter… moreYou have some seriously high standards. Good luck lasting your s4 for at least another five years.

  4. Well the graphics let the P9 looks bad. Let the first-picture compare with the 3 alltime-best and some other current devices.

  5. Great life. Better than Galaxsi S7 and S7 EDGE snapdragons.

    The time you have to wait for battery life to progress that far is probably beyond the time your S4 has in this world.

  9. Assefa, 10 hours agobuy an oukitel k10000I bought an Oukitel K10000 and waiting for it to arrive. It’s about time some OEM slabs a monster battery like that on a phone. True, the rest of the specs are average but as a secondary phone it boosts days of battery life without compromise.

  10. Anonymous, 11 hours agoI am still using the galaxy s4 and i will not buy another smartphone until they improve batter… moreHey uhh…I think everyone thinks otherwise cause the comments are all kinda going against what you’re saying, lol.

  11. Pretty low, s7 with QHD and 3k mah battery has 80 hrs endurance ratings.

  12. We can conclude that China’s brand had caught up with every aspects in a phone technology, except only one, software optimization that result in good battery life…. Wish all chinese brands will spend more on improving a phone battery life…

  13. Anonymous, 11 hours agoI am still using the galaxy s4 and i will not buy another smartphone until they improve batter… moreSame here. Still using s5. But i m thinking to update my self to Huawei p9 plus. I like the design and build quality. I think it’s the best mobile available on the earth.

  14. Anonymous, 11 hours agoI am still using the galaxy s4 and i will not buy another smartphone until they improve batter… moreYou will probably be 100 years old by the time that happens.

  15. As far as battery saving option is not about disabling features like nfc/wifi/lte(when using phone not in stanby)it should be take in to the account in battery test because let’s be honest it’s first option that you enable in phones today.
