So after trying Microsoft Edge for 3 days in a row, I found that that it's one of the worst browser that MS released. It's worse than Chrome in CPU and RAM hogging! My fans never stopped spinning when that I'm using that POS Edge browser. Now I'm currently typing this on the desktop IE in tablet mode and I so badly want my MetroIE back. Whoever thought to get rid of Metro IE in Windows 10 should get fired!. Windows 8.1 is still more efficient in an actual tablet use mode (running 90-100% modern apps as opposed to desktop programs) because 8.1 actually suspends those apps when not in the foreground while Windows 10 keeps running them in the background, consuming CPU usage (I'm looking at that POS Edge browser that sucks up almost one full core of my Sp3 i5 on the background while running other apps in tablet mode) Now I figured why in Windows 8, I idle at consistent 0% CPU @ 0.75GHz while Windows 10 rarely idles at 0% usage and almost all the time @ 1-5% use @ 0.8 - 1.2GHz, which pretty much kills 30-1 hour of battery life cumulatively.
