There are too many variables into the equation...I get 5.5hrs max of SOT with screen on QHD+ 120hz enabled, wifi connected and galaxy watch connected. I have been trying to limit background apps an so but can't survive for more than 5.5hrs.
Max my phone lasts is for 18-19hrs with 5.5hrs of SOT.
I have gone through several reviews of people claiming 8hrs+
I don't even have heavy usage, all I use is WhatsApp, YouTube and chrome and a bit of Facebook.
Considering how light the usage is surely the battery life sucks?
As enigmaamit above also said that he has mixed usage and still gets 6+ hrs and mine is light usage and it still struggles so I wonder is this normal?
FB uses plenty of battery for one.
Two, maybe where you are, your phone isn't catching great signal. usually when that happens, it drains the battery as the device is constantly trying to get better signal.
Maybe since you are not rooted you have plenty of bloatware that is draining your battery.
Additionally, putting usused apps to sleep, adaptive battery being ON, and also maybe you are using white mode instead of dark mode. Dark mode saves plenty of battery on our amoled screens.
Also I am rooted. So no bloatware. Battery fully calibrated. No draining apps. I use FB trough my KIWI browser with dark mode on for all pages.
If you get a full day, you are good.
