    I too went from s10 to s20/21. I've noticed my battery on the s10 to be "better" than on the 20/21.

    Even with the bigger battery, battery didn't last as long as the 10. My theory is because the 20/21 are 5g phones.

    I'm on VZW. unfortunately I cannot turn off my 5g signal

    Is 5g a battery drain even if no 5g signal? I don't have 5g at home and Don't think I'll be able to make use of 5g until I can travel again so would probably turn off to add even more battery life!

    I could be wrong, but with the 5g being enabled, it's constantly searching for 5g/UWB signal. Hence the less than stellar battery life.

    I'm on vzw's 5g UWB service. My phone constantly searches for 5g signal. Switching from 4g to 5g.

    I don't think VZW allows you to switch over to 4g only. At least I couldn't find that option under networks.

    I have a 5G plan on EE on SIM #1 and although I cannot receive 5G at home yet, I leave it enabled for travelling. My 2nd SIM is GiffGaff and not on a 5G plan and that is switched to LTE. I do not notice any undue battery drain by using the 5G option on EE.

    Yeah my situation is same (I'm on Vodafone though) and 5g is unlikely at my home address for the foreseeable future.

    I thought about turning off 5g to save battery but in all honesty I'm impressed with battery life already. Plus I'll probably forget to turn it back on when I'm travelling!!

    Coming from the S10 to the regular S21 I am noticing a huge difference in battery life. On the S10 it estimated almost 18hrs of battery life where the S21 is estimating only 10hrs. I notice the difference too. Just from light browsing I can see the battery percentage go down by 1% every other minute or so. Even after 2 years with the S10 my battery would last until 5 or 6pm.

    Shouldn't I be getting better battery life with this display? I checked all settings and everything is set up the same as my old phone.

    Another thing is the S21 doesn't charge nearly as fast as the S10 does.
    Exactly same problem here with S21 Exynos.

    I also switched from an S10 to the S21, and below is my S21 battery status. It shows 22 hours of battery time after a full charge based on my daily usage.

    Granted, because of the COVID lockdown I haven't traveled much away from my home, so maybe that is affecting my battery usage?
