BATTERY DRAIN

The battery life of phone is decreased by 2 - 4 hours per 100%
Even with simple apps like spotify or samsung music it pulls out a lot of battery and while gaming even on battery saver its drain so fast now and also other issue is heat that phone is heating so badly on even normal to moderate tasks I think the phone softaware currently support light use only to give a better thermal performance and a 5 to 6 hrs battery life in 100% even when im following all precautions and optimization tricks like timeout refresh rate and power saving (battery also drains more in power saving even more in super),dark mode 4g network etc ....this issue is unacceptable for us users as with every update the battery is going worse and there are no improvements in it ....my old Galaxy a6 + has a 3500 mah battery but it was giving similarly less battery performance than this even in more use like it was 12h in 100% with games etc all even if u have to charge it all along in short time cuz of smaller battery and its same Samsung
