Hmm room for improvement then haha. Let's hope it stops being alpha soon. Looking for a new daily driver rom without any drain issue that stock rom gives me.. And since drains and Oreo seem to go hand in hand so I figured why not go for pie lol.
I made a clean install of this alpha release (up-to-date version when posting), everything went smooth and clean. I used aroma opengapps to be able to choose whatever Google app I want. It's been 4 days, using the smartphone about 5 hours using WiFi then shutting the device off. No noticeable issue despite the automatic backlighting not working. For a first time alternate ROM, and an alpha ROM, it was great.
