Any power management tips / annoyed at low battery life its meant to be a laptop ffs

Running pure os on a brand new librem v2 and my total battery life whilst running android studio is about 2 hours tops (coding, searching documentation, building etc), (no where near what the widget originally predicted which was 7), considering that batteries degrade over time especially with constant charging/recharging this will likely get worse and probably relatively fast, It’s a laptop, not a desktop and I don’t want to have to lug around three extra batteries to get me through the day. Does anyone have any power saving tips or any suggestions on what i might be doing wrong?

p.s laptop gets hot as well but i reckon this is expected.
