The P9’s battery results will also be interesting as there is a HiSilicon SoC inside rather than the usual Qualcomm silicon. The Kirin 955 does use a modern 16nm FinFET manufacturing process, so it won’t have a process disadvantage compared to Qualcomm, but we do already know that the Snapdragon 820 made big strides in performance per watt while cutting down throttling issues.
In the above battery benchmarks, the Huawei P9 puts up a standard performance for its SoC and battery capacity. In most situations it delivers slightly above average battery life, which is perfectly fine for everyday use, and it matches or beats competing devices with reasonable battery life like the HTC 10.
One of the disappointing things about the Huawei P9 is a lack of fast charging. A full charge takes well over two hours, with particularly slow charging between 90 and 100 percent. Burst charging is surprisingly good from the included charger, but it can’t match newer flagships with Qualcomm Quick Charge 3.0, like the HTC 10 and LG G5.
