I just purchased Samsung galaxy note20 ultra 5g UAE version last month but it was seen that my phone battery drains quickly. In just 12 hours 100% batery got finished while i only use whatsapp for for operational purposes and no any game or or media play on this device. I also put my phone on 60hz instead of 120hz and brightness level low to save battery. Is it only happening with my device or all the note20 ultra users faced the same battery issue?
Thanks for your assistance.
Wait for a week more or a month atleast cause the phone will adjust to examine your usage you then work around. Don't forget to hold the app and restrict the background usage for apps you don't use.
Try make power saving mode or dark mode and watch battery usage in setting try to see what is the most app uses battery and make sure you charge with original charger and cable ....if this is not solving then try replace the phone not the battery
