hey guys i downloaded 2160p video it's a 30 min video and size is around 5 gb when i did run it on my laptop on vlc player it's running with lag i opened task manager and where i can see my vlc player using 60% CPU you know what it's mean my 100% battery will finish in just 30 min the more cpu use by any processor the more your power will consume mostly cpu like 80% use on Rendering process but now i know it's also use on this type process too and then i run 1080p video and saw it's using 20% Cpu so keep in mind don't download ultra HD type video until you have a big screen to watch it like you have a android phone and you download 1080 or 720p no matter you will not see any different because you need a big screen to different between pixels and android screen is short movie like 2160p is made for projector play so you can see it clearly and also can compare with low pixel videos you will see the different so don't waste you data to download big size video and just too show off just keep in mind main reason behind this. my laptop is i3, 4gb ram, 2gb graphics if you have different config cpu will use less or more then mine during running 2160p video.
