Huawei Mate 9 battery life test results are out: beats iPhone 7 Plus, Galaxy S7 Edge and Pixel XL


The Huawei Mate 9 battery life test has finished and the score is out. Does it live up to Huawei's promise of real, 2-day battery life? And can it beat other big phones like the Apple iPhone 7 Plus, Samsung's Galaxy S7 Edge and the Google Pixel XL?

The answer is a resounding 'yes'.

The Huawei Mate 9 scored a nearly 50% better battery life results than the competition and it beat the iPhone 7 Plus by offering a third more battery life.

In our custom test where we put the phones through typical use case scenario, the 4,000 mAh battery on the Mate 9 kept the phone running on and on, and then on again. It scores a whopping 12 hours and 14 minutes, while the iPhone 7 Plus (one of the better achievers) scored just 9 hours and 5 minutes and the Samsung Galaxy S7 Edge got 7 hours and 18 minutes, nearly half the battery life of the Mate 9.

Luckily, this coincides with excellent stand-by time and we are indeed getting two days of battery life with the Mate 9, which definitely feels freeing. You no longer need to charge your phone every night, and that's good not just because it keeps you from thinking about one more device to charge, but because you put fewer cycles on the battery and it will last you more in the long run. Excellent job, Huawei!

Battery life (hours) Higher is better
Huawei Mate 9 12h 14 min (Excellent)
Apple iPhone 7 Plus 9h 5 min (Good)
Google Pixel XL 7h 19 min (Average)
OnePlus 3T 5h 41 min (Poor)
LG V20 6h 23 min (Poor)
Samsung Galaxy S7 edge 7h 18 min (Average)

When it comes to re-charge times, the Huawei Mate 9 has quite the large battery to replenish, and it took it 2 hours and 24 minutes to get the 4,000 mAh cell from 0 to 100% using the stock wall charger. While not fast by any means, this charge rate is still faster than the one on the iPhone 7 Plus, which took an even longer 3 hours and 17 minutes to accomplish the same task.

Admittedly, other phones with quick charging are much faster getting juiced up: the Galaxy S7 Edge does this exercise in just 1 hour and 40 minutes, while the OnePlust 3T takes just an hour and 25 minutes to get its battery fully charged with Dash Charge technology.

Charging time (minutes) Lower is better
Huawei Mate 9 144
Apple iPhone 7 Plus 197
Google Pixel XL 118
OnePlus 3T 85
LG V20 86
Samsung Galaxy S7 edge 99
Huawei Mate 8 156

Nonetheless, if you are looking for a reliable and powerful phone with a great battery life, the Huawei Mate 9 certainly delivers. It's also one of the first high-end Huawei phones that you can officially buy in the United States. Currently, the Mate 9 is on sale at Amazon for a very alluring full retail price of $600, compared to $770 for similar iPhone 7 Plus or Google Pixel XL.
