What do you mean by normal sleep and pretty well? My XPS isn’t that old and it drinks from battery while sleeping quite fast, 12h and 50% goes down.
My older Dell laptop only drains 1-2% per hour on normal sleep which is also not acceptable, I can’t leave it like that over the weekend.
Nobody’s mentioning putting laptops into deep sleep where no battery power is being used.
Oh how do I do this? Can you choose what processes it kills first even if they’re not the worst offenders?
Yep, the Firefox thing is weird. I’d run a memory test . Does this laptop do the same thing with Windows?
Also op mentions 20 years, were your other experiences like this?
Well we had 3d TVs 10 years ago
