@nprofile1q...Not if I watch videos. But my Xiaomi 10t pro with LineageOS (without Google play services and other bloat) makes a full day for me (Surfing, Fediverse, Messaging and calls). I stop charging at 80% for battery protection. I bought it mid 2021.
I disabled stuff like locationservices, autoratations and other stuff I only need rarely to need less power.
According to LOS the battery has still a capacity of 4.339 mAh out of 5.000 mAh.
