S21 Ultra 512gb battery concerns

[Phoenix142]

My family in the past week have between Monday and Saturday purchased 3x S21-U 512gb/16gb models which are all showing ALARMING battery issues.

Even after a few days with very light use and proper management of charging and settings to accommodate, at light use(browsing a little news on chrome, watching light video and playing a game for 10 to 20mins ) the batteries on all 3 drains 50% in 90 to 150 minutes with low refresh rate, low screen resolution, no wireless communication on except WiFi.

Heat? The phones all overheat after 5 to 30 mins of use regardless of task or performance settings and mostly ask you to stop using the device or point blank shut everything down for you.

All 3 phones show in 5 different battery apps after 3 days (2 days on newest one)similar concerns, the 5000mAh promised with a minimum of 4855mAh only Contains 4399mAh and show a life of 89-91% health between all 3. They are all between 2 and 7 days old.

None of this makes sense and samsungs best answer via chat was to replace all 3 via retailers? 

Are you serious? Nearly 4000 pounds of hardware from completely different places and batches? This is a design or software flaw.

Some sort of communication from Samsung would be nice to set expectations or if a permanent switch to another manufacturer is needed due to poor quality of such a pricey device and one launched less than 6 weeks ago.

Lastly I'd like to point out, this isn't just our 3, it's happening on 8 different friends phones same models ranging in sizes only between 256gb and 512gb.

That's 11 models from wildly different areas, production batches etc.

Samsung, you can't excuse this as a single batch of defective units and this is all over the Web and social media with what I can assume so far is more than 80% of buyers currently having severe issues with the above. 

Be cautious when buying these until you can see the market responding to the updates coming.

accubattery won't get anywhere near an accurate reading for a good few weeks and full charges.
you should look at using GSAM for battery drain issues

[Phoenix142]

Read my post my friend. I use 5 different ones GSAM included. same result across the 3 phones.

based on the fact there's thousands of these cases, I no longer believe in the bad batch lol 😆

you're right though. takes a while, but this isn't just 1 phone, it's 11

all the best you . thanks again 👍

heating should go away after some use.
turn on battery saver. it kills all unnecessary background activities.
if you used S Switch to transfer old phone data... expect to some corruption due to old files somewhere. reinstall any app you find suspicious and using resources that are draining your batteries.

after very heavy use, I am using be almost half the battery in some 8 hours.

make sure you go to settings and update your phone with latest patch. it helped me.

it's getting difficult to see the picture and I appreciate your reply but all this has been covered, I'm quite tech savvy and have literally done everything possible with all 3 devices, I find it peculiar that with or without S-Switch I get the same result, and as above, the same occurs on 8 other peoples devices in my family/friends circle all 11 on the 256gb or 512gb model.

normally, I'd accept heating and battery problems for the first few days to a week due to syncing and all sorts on the background as well as adaptive well, adapting to your use etc. but after a full week on light to medium use 2 of the phones are showing the same problems, one has been update one has not.

again though. appreciate the reply 👍

edit: also. After contacting samsung, they suggested replacing all 3 handsets. bit odd.
