Battery Life
Battery life of a device is dictated by the SoC efficiency, screen efficiency and battery capacity. The Mi9 has an efficient SoC, and it should have an adequately efficient screen, however its battery capacity of 3300mAh is on the lower side compared to competitor devices this year, which are found to sport 3700-4000+ mAh units.
In the web-browsing test, the Mi9 ends up as expected on the lower half of our device database of recent flagships. The phone lands near where the G8 landed.
Similarly, in PCMark, the Mi9 ends up quite average in terms of its longevity. It’s not bad at all, but still remains as the lowest longevity of S855 devices, just a hair worse than the 90Hz mode of the OnePlus 7 Pro.
Overall while the Mi9 certainly doesn’t compete in battery to the likes of the Galaxy S10+, it should offer sufficient longevity to get most users through the day.

Nice review. Would be very interested in a Xiaomi Mi 9T Pro review if you manage to get your hands on it. Seems to be an upgrade on some aspects of this phone.Andrei Frumusanu - Friday, September 13, 2019 - link
Among the upcoming reviews, iPhone 11, Mate 30, Pixel 4 in the foreseeable future I don't think we'll have time for the Mi9T Pro, sorry.yeeeeman - Friday, September 13, 2019 - link
Why not Galaxy s10 with exynos 9825? Pixel 4 has Qualcomm 855 which we know. Huawei mate 30 will have Kirin 980 which again we know. iPhone is interesting, sure, but 9825 being a shrink it is curious to see what the impact is. Come on, it is launched for over a month now....Andrei Frumusanu - Friday, September 13, 2019 - link
We're not getting sampled by Samsung so we'd have to buy one. Currently the 9825 doesn't represent any notable performance difference, the Note10 doesn't have any notable camera differences, so other than the chip's power efficiency for an academic view on 7EUV it's lower on the priority list than the aforementioned new devices.s.yu - Saturday, September 14, 2019 - link

No worries, I'm interested in those devices too so should be interesting!AkiraAkimoto - Saturday, September 14, 2019 - link
Will you review the latest Vivo flagship Nex 3 and the Xiaomi's flagship Mixα？Rumor says that the Mix series will have a great leap comparing with the previous Xiaomi deviceRedmyth79 - Friday, September 13, 2019 - link
This site is not accurate so the 9Tpro would never get a fair shake. Trust me I own a lot of the phone es tested including the Mi 9. The Mi 9 test higher then the 9Tpro also so you know but the scores hear are apparently made to make them not look up to par with the other Flagship phones with 855 chip sets. Hell the 980 Kirin is from last year on the P30 pro and I know for a fact in 99% of test it doesn't come close to any 855 chipped phone much less a Mi 9 that truthfully on any other site including a lot of the actual test here it best out 99.9% of the phone es and the S10+ actually does about the worse of any but here some how it's rated near the top and the mi 9 is no where near where it should be. It's a crying shame.Cellar Door - Friday, September 13, 2019 - link
This site should get mods for troll account like this.
