First of all, I'd like to point out the laptop that I'm using, it's a Dell Inspiron 5570 (i7-8550U + AMD GPU), now onto the problem.
The most annoying issue I faced (installed elementary OS twice, checked the MD5 checksums which were identical but still encountered the same issue) is that when plugged in, the estimated time till battery's full is really high, and the battery takes so much time to charge, unlike Ubuntu 16.04 which is very quick and doesn't take nearly as much time as elementary OS Loki, which lead me to think elementary OS Loki has driver problems with my Laptop and correct me if I'm wrong but isn't elementary OS based on Ubuntu which should probably use the same drivers. (forgive me if I'm wrong as I'm new to the Linux world)
What do you guys think this might be?
Thanks a lot in advance.
