Anybody else finding there phone battery draining recently. I can leave it do nothing and lose 10%. Normally I can get through a day quite easily, YouTube, Instagram, podcasts but recently I'm getting to about 8pm and having to charge it.
Also noticing when I take a photo, it's no longer instant. The lag is really bad.
Hay, I don't have the S21, but do have the Note 20 5G Ultra and over the last couple of weeks I have noticed, like you, my battery is draining a lot, even when not used. I know the heat can drain it, but even when it's inside it is the same. I have done the battery and device care and it does not seem to have made a difference ... I have even deleted some apps, pictures (WhatsApp) etc. And still the same!! I am thinking it is something to do with an update, as I've had a few and it appears to have started around the same time.
