So I've gone through all the possible settings guides, tips, cleared cache after every update, used galaxy booster app.
I also have the latest June update, really everything there is that can possibly help me get a better battery life (using FHD and 120hz which I won't give up).
Even got the phone company to provide me with a new Galaxy s21U since I've figured the first one was faulty.
After all that I still can't manage to get even 7 hours SOT (when I'm at home using WIFI no cellular data no Volte no 5G etc.)
Using standard apps like Whatsapp, Mails, Chrome , Facebook.
Usually I'm getting around 6-6.5 hours SOT and if I'm out of home using mobile data or god forbidden GPS, I'm getting around 5 hours SOT.
I really don't no what to do?! I've had an old Huawei Mate 10 Pro which had a 2 times better battery life.
You're saying that my SOT is comparable to yours and you have on 5G, wqhd, always Bluetooth on etc.
I have none of these things on but I still get the same SOT as you are, that's what I don't understand.
I think you are not using facebook, whatsapp, twitter and other social media apps. 8 hours SOT is just impossible on S21 6.2 inch. I get 5 hours SOT max with all restrictions in place.
