Cough...Lmao, Xiaomi did the worst 888 smartphones with the Mi 11 and Mi 11 Ultra in terms of battery consumption. Even the Ultra has worse battery life than OP9 Pro and Oppo Find X3 Pro that have 10% less battery capacity.
More than 1 day with beavy usage? Even with light use, i struggle to get 24h with no more than 3h of SOT. Average, it last me 18h with 5h of SOT with light use, 60hz FHD+
