Regardless of my exams happening right now, the minor red tint on the top of my display was bothering me so I manually flashed the AQDG update which hasn't been released for the Pakistani CSC yet (read first post), I flashed it and CSC matched the ROM, restored my Smart Switch backup and I can say I'm very impressed with how Samsung pulled it off.
Not only did the red tint disappear completely, the performance has improved and the battery life is phenomenal.
I unplugged phone this morning at 8 AM, used it for a while, it was 86% when I left for school at 12 PM, I came back at 3:40 PM, and it was 84%.
It is now 6:35 PM and it is 71%, keep in mind there was heavy Snapchat and Telegram use when I came back and the former is a huge battery hog.
I've gotten 2 hours and 50 minutes of SOT and there's 71% remaining. At this rate I'll find it very difficult to run out by night time so I can put it on charge.
Absolutely loving this phone.
