Battery Life - The Bad News
When it comes to battery life, the Mi 11 sports a 4600mAh battery, and comes with the newer Snapdragon 888 SoC. We’ve already seen that the new chip isn’t quite as power-efficient as its predecessor, requiring more energy to achieve its higher performance levels.
However, the biggest issue for the Mi 11 is its idle power consumption, which is just terrible. Under all situations, even under 60Hz, the device will consume in excess of 700mW when displaying a black screen, and this figure goes up to the 900’s mW’s when under 120Hz mode. These are pretty horrible figures and bad news for the device, as it’s a constant power drain that happens no matter what you’re doing with the phone, especially dominant for battery life at lower brightness levels.
I don’t know exactly why this is happening to the phone, but’s the lack of VRR makes the situation even worse.
Edit March 12th: The Mi 11 does have a coarse software-based refresh rate switching mechanism, however it does not function below 110 nits screen brightness (around 70% on the brightness slider). The battery tests below should have had the feature functioning given we test at 200 nits.
Due to the high base power consumption, the phone doesn’t do all to well in the web browsing test. The most interesting device to compare things to is the OnePlus 8 Pro, which also features a QHD 120Hz screen of a similar generation, and both devices end up towards the bottom part of our battery life results here. It’s interesting to see that the 60Hz to 120Hz delta is smaller than that of the OnePlus 8 Pro. At 60Hz, the Mi 11 also does worse than the Mi 10 Pro.
In PCMark, the Mi 11 does averagely at 60Hz, but at 120Hz it’s really falling behind by a lot and bottoms our chart again, near the Exynos S21.
When it comes to weaknesses of the Mi 11, battery life is probably its biggest one. While performance and screen quality are great on the phone, the SoC remains very power hungry, and the screen is as well. The situation is exacerbated by the very high and unusual base power consumption of the device. I don’t know where the problem lies here, but given Xiaomi hasn’t fixed it in a firmware update yet signifies it’s some hardware mis-design that’s unlikely to get changed by software.

What a well thought out reply. Thanks.zamroni - Wednesday, March 17, 2021 - link
I still use galaxy s9 as my current phone.Curved edge screen sucks.
It also less durable.
My screen replacement also costed ~$100 more than flat s10e

Curved edges: Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.Findecanor - Wednesday, March 10, 2021 - link
Curved edge means more likely to break if droppedballsystemlord - Wednesday, March 10, 2021 - link
Shouldn't it be less likely because of the force vectors involved?RSAUser - Thursday, March 11, 2021 - link
No due to how the glass is folded, force distribution is worse. Also getting cases that work well is more difficult.Spunjji - Thursday, March 11, 2021 - link
In theory, but the main problem is the total inability to fit a full-coverage screen protector.Unashamed_unoriginal_username_x86 - Wednesday, March 10, 2021 - link

Is Mi 11 using it LTPO OLED?
