So i have a lenovo Tab P12 (TB370FU, 8GB RAM, Dimensity 7050, 256GB storage) and i noticed the battery was draining a lot faster after i upgraded to android 15
A quick check from CPU-Z and i think i have discovered the problem, whenever the tablet receives input from the stylus/touchscreen/keyboard the CPU jumps to 100% clock speeds (2600 on the two P cores, 2000 on the six E cores), when it's not recieving any input it sits happily at the base clocks of 500 MHz (650 for the two P cores). Even simple stuff like resting your finger on the screen or touchpad makes it run fast which is kind of a big deal because i use this as my typing/sketching primary device [it's handier than booting a laptop afterall]
The build ID is TB370FU_ROW_OPEN_USER_V5_V_ZUI_17.0.187_ST_250817
The tablet's stopped recieving OS updates since it started off android 13
My question at hand, what would fix this? Should i try resetting the tablet or maybe look deeper into downgrading to older builds (presumably one on android 14?)
