Well. Grand 2 is my backup phone now so i dont need fancy stuffs. I just need basic funtions work like sim, wifi and i can watch videos with it fluently. The battery seems fine to me. I used to love your J2 Hybrid Rom, just hated that watching videos is very difficult.Well TW-MM for S5 Mini was unoptimized anyway. Remember we are using an old device which starts from KK and some even from JB!. Im reducing battery drain by removing trillions of features and services from TW-MM framework(Not from this ROM though).
