S21 Ultra Battery life really bad compared to all the youtube video review

[daribeiro]

So I bought the new S21 Ultra on the pre order the day it was announced. I was one of the lucky ones to get early so I could leave a review. 

Coming from a Note 10+ that I had for a year and a half, I was really excited for the S21 Ultra, but was really disappointed with the battery life. I've had the phone for 5 days now and since the very beginning I've not been able to use the phone for the whole day on a single charge. It's been giving me screen on times comparable to my Note 10+ (4/5 hours) which is a much older device, but I thought maybe this was the way all S21 ultra's were behaving, just not very good battery life.

BUT, yesterday all the youtubers started to publish they're videos comparing batteries with older S devices and Iphones and their S21s were doing amazing, giving them screen on times of up to 13 hours! 

I contacted support but they said this would be normal as my phone was still learning user patterns... but I'm not sure if that would affect it as bad as it is at the moment. 

What do you guys think? Should I send the phone back? I'm really concerned that I just spent all this money on a new phone for it to be so bad with battery.

I have no idea. But I got an update today. hopping it fixed the problem. I'll wait a few days to see. otherwise I'm returning it

Same problem here. Battery life sucks! i'm at 85 % after 45 minutes of turned on display! Yesterday at 16 i was at 25%!! How is it possible!?!? i also uninstall smarthing ( which is so usefull for me, having so many smart things) but it seems nothing is changing!

[daribeiro]

yeah for me for sure it isn't smart things. I'm starting to think it's Chrome. I don't use it that much but it's always on the top of the list of the apps that use more battery... I wish I could put it on deep.sleep but it doesn't allow me to do that

The same thing for me chrome is always on the top of the usage , but i think you will complete 8 hrs on screen and this is a good number for on screen with adaptive 1480 , it improved than yesterday?

 

[daribeiro]

I think the phone is counting since the last full charge. last time I only charged it till 75% so it's adding up the time before that charge

Guys i never seen more than 4.30 hours of display turned on!!
