How bad is battery life on Linux laptop?
I will need to get a laptop in the foreseeable future, and I really want to stick to Linux. However, I may need to be out-of-home for 12+ hours straight in a day. After some research, it seems people are generally not that impressed with battery life on Linux?
The laptop does not need to do anything heavy duty, as I will remote back into my already very beefy desktop back home.
I guess a common solution to this light use case is M2 MacBook if one wants to completely throw battery concern out of the window. Well... let's just say it's a love-hate relationship.

Some addition power management tools I suppose?
vanilla with no configuration.
tlp is enough
Tlp and Intel xtu for undervolting (lowers temps and power consumption, but newer cpus don't support it) are pretty good ideas. If battery life is your perogative, try avoiding discrete gpus, they can be a pain to make sure they don't drain battery in Linux. 14hrs is possible, but you have to spec properly (think thinkpad t480 with dual batteries, and a low power display).
