Hi I just installed elementary OS 5.1.7 Hera, and my battery lasts 10min.
My laptop: Dual-Core Intel® Core™ i5-7200U CPU @ 2.50GHz Intel Corporation HD Graphics 620 (rev 02) NVIDIA Corporation GP108M [GeForce MX150] (rev a1) 8,1 GB memory
I was using loki before that, and I could watch a movie (720p - 2 hours), now it's 10min with screen on.
Previous installation I had nothing special installed for the battery.
Do you have any idea what I might do to fix that?
