I think I should at least be able to browse the internet, its gotten to the point where I just leave my laptop off and use my iPhone 6 to watch movies when I am in bed because my iPhone 6 runs everything fine. I understand that devices get old and slow down, I am not expecting to do anything heavy on this laptop but I can't even browse the internet without my MacBook running extremely slow even if nothing else is running in the back.

The MacBook Pro says I need to replace the battery soon, maybe replacing that will fix the issue? I have no idea what I have to do or buy to improve the performance, I thought maybe it was my HD but I reformatted and installed El Capitan on a different HD a few days ago and its the same issue. I have cox cable and get up to 100mb download speed so my internet speed isn't the issue, I can watch HD movies with no issues on my iPhone and desktop computer.

This is what I have to deal with using this laptop, in the second video it shows my iPhone 6 running twitch no problem on source while my MBP looks like its going to have a heart attack trying to run Twitch. (watch at 2:30 when I try to watch a twitch stream)
