Stock EU? You mean EEA? Xiaomi EU is a custom rom. I 'm a member of a swedish android forum and most members there get poor battery life on Mi 11.Well, I use the stock EU ROM and I'm currently averaging 6 hours of SOT per day and use NO battery saving features. I'm using 120hz and FHD+. Also, I have 5G disabled since here in the USA in my area it isn't supported. But I get full 4G-LTE coverage. Not sure what you all are doing wrong.
Do you use wifi or lte? I don't think you get great battery life due to MIUI 12.5. Instead, you probably use your phone in a different way than most other people.
People who use LTE instead of wifi seems to get better battery life. Also, screen brightness makes a large difference. People who use their phone in a bright enviroment will have less SOT due to higher screen brightness. Also, watching video will drain the battery less than web browsing etc.
"Besides the inefficient cooling of the Snapdragon 888, one of the reasons for the relatively low endurance is the WLAN modem, because the Xiaomi phone lasts almost twice as long in our continuous video loop with the WLAN disabled."
The Xiaomi Mi 11 uses the brand-new Qualcomm Snapdragon 888. Find out what you need to know before buying it here.
