Hi, i have read many answers / solutions. I have struggling with slow browsers for a few days already (almost a week). So maybe anyone could help: COMPUTER: dell xps 13 9360, 16 gb, 512 ssd, i7. killer wireless 1353. Bios newest. Win 10). New fresh computer from shop (only few days), so no malware or anything.Very slow browser. Chrome is jittering. Firefox is a little bit faster. Struggling with YouTube, Facebook, even this forum. But sometimes everything works. (when it is good speedtest: local server: 100/100 mbps. To usa 40/15 mbps). but sometimes its feel like i'm running windows 8 on Pentium 2 :D. Impossible.I googled a lot, and tried a lot. What i have determined: Last observation (Just now) everything works almost good (of course after all steps above). But only wen AC cable (charging) is in. When everything is running on battery - Houston, we have a problem. So my question is:what could i try, to make this problem WIFI (without charging cable) improvement???And overall browser speed ? 
SLOW WIFI (Browsers) when not charing (AC). Dell xps 13, 9360, i7 16 GB, 512
