This is with regular usage..charged to 88% yesterday night. Removed power saving mode and battery dropped to 80%. I forgot and charged it backed to 99% before starting my day.AOD on all day. 45 mins WhatsApp videocall and streaming. Got 6 hours.
Replacing battery would significantly increase your screen on time. I replaced my s24U battery and now I easily get 7+ hours of Screen time. I do use the phone in power saving mode 24/7.
