Stopped charging my laptop to 100% and it made a difference

I used to plug my HP in every night and let it sit at 100% until morning. Did that for about 18 months. Then last December I noticed the battery would only last maybe 2 hours before dying, used to get closer to 5. Buddy of mine who fixes electronics told me keeping it topped off all the time kills lithium batteries faster. So I changed two things: I started unplugging once it hit 80%, and I only charge it back up when it gets down to 20%. It's been 4 months now and the battery life is holding steady around 4 hours still. I don't even plug it in overnight anymore, just top it off during lunch when I'm at my desk. Has anyone else tried this and seen their laptop battery last longer?

Wonder if heat from charging to 100% is what really does the damage.

And honestly heat is the real killer, not 100% itself. All that extra current ramps up the temp way more than people realize. Keeps it cool and you will be fine mostly.
