Bad Battery Backup

[Ganesh6401]

My Galaxy M21 Is Giving Bad Battery Backup even with 6000Mah battery+AMOLED Dark mode.i don't know whether it's because of bad software optimization or exynos 9611 is power hungry...on oneui 2.5 this phone is giving me very good battery backup but after updates its giving me bad Battery Backup.My SOT is 11-12 hours without gaming....even my 3 year old Note 7 Pro with old 4000Mah battery is giving me 10-11 hours SOT in similar usage😔...SAMSUNG Please Optimise your  LEGENDARY EXYNOS 9611.....

Below Are Pics Of My Almost 3 Year Old Note 7 Pro With SNAPDRAGON 675 and LCD Panel(not even replaced with new battery)

Lol MI is giving more battery backup so that they can sqeeze more data to china. Jokes apart..10hr sot is good. Why would anyone use a phone 10hr plus straight. Charge it between mahn, that's what chargers are for!
