How long have you had the phone? It might just be a crap battery.

My battery is nowhere near as good as it was but I've had mine 3 years, so I couldn't tell you if it's 12's fault

I've had it since March 21 but updating from the last versions OneUI 3.1 to 4.0 was an overnight difference.
I run an FE group on telegram, pretty everybody has noticed for our phones but it goes beyond Samsung. Pixel users have noticed and complained over it.
the one guy I know who never bothered to update at all from day 1 says his battery life is still stellar.

Have my s20 for 2 years now. On OneUI 4.1 currently. Battery life has degraded very little for my suprise. It does have the exynos tho that was bad from the start for battery. This far im not seeing a problem. If i use bluetooth music all day it still has 60 percent by the evening. If i dont listen to music it holds almost 2 days.

that's pretty good compared to some SoT posts I've seen for the Exynos 990.

some poor guys are just getting 3 hrs screen on.

That really is piss poor. I'd thow my phone in the bin if the battery was that bad

You don't expect that on top end devices

the exy 990 is a bad chip, in fact any chip fabbed by Samsung just isn't ever as good as chips fabbed by TSMC even if it's the exact same chip and Samsung has taken over production of it.

Samsung LSI are going through a difficult time for the last few years, the Exynos 7420 days are long gone it seems. Samsung LSI need to take a break for a year or two and figure themselves out, lol!
Even with Snapdragon the new Snapdragon 8 Plus Gen 1 fabricated by TSMC seems to be quite a leap from Samsung fabricated Snapdragon 8 Gen 1 in terms of efficiency and performance sustainability.

Wish we had the option to get a snapdragon version. Currently thinking about getting a new phone with a bigger screen but there is nothing to choose from. The s22 are a letdown with no sd card support. I would like to keep using my 128 samsung evo card not to just throw it in a drawer to collect dust. Had it since i got the s8. They also should have atleast bigger memory options that dont add so much to the price. Im too used to samsung its hard to get something else.

3 hrs is bad. Maybe they keep it on full brightness. I always have it half way on all the phones i have had. Only push it up in sunlight.

I do about 25 percent indoors, dark mode helps make it readable.

Well, I haven't noticed any battery performance issues on my OnePlus Nord 200 since it received the Android 12 update.

Really wanted a bigger phone and for a samsung sheep there was only one real upgrade for me from the s20. Got the s22 ultra with the exynos 2200. Dont know if i should stress about paying too much for a phone or the fact that its another exynos with poor performance and battery life I saw on yt that it has a adaptive battery thing where it learns to hold juice in 2 weeks and just plain sucks for 2 weeks. Overall does not seem to be the worst chip. Will give it a go and see if it is good or bad. Rumors are that the s23 will be snapdragon only. Was not willing to wait a year for it to launch and also get a bit down in price etc.

Why cant any of them just make a all around perfect phone. Each upgrade time its always a compromise on what to get. I highly recommend Flossy Carter on youtube if anyone is looking for a good review on phones. Highly entertaining and detailed real world reviews that are not too technical.

Makes you wonder why the battery is having to work so much harder. Sounds like data collection to me.

Mine's the same. It's a Redmi Note 9 with a battery over half an amp hour. Huge battery for it's time.

After the last update I found it'd switched on geo-tagging photos. I've fully had enough of that security issue.

my battery has improved lasting an extra hour since android 12

Mine says it lasts 1 day 17 hours. It used to be double that when I first had it

That's telling u to buy new phone politely tramp

What a horrible person you are
