The Samsung Galaxy S21 Ultra Has a Problem!

[@reconliving]

My only battery problem is it won't run out and I'm wasting way too much time checking it waiting for it to run out.

I am exactly the same Recon!.. My Exynos S21 Ultra just won't die even I really extend it!. Is this inconsistency a chip or software problem?.

[@iTz_RaptorV1]

Your phone must be defective because I run my phone to its limits and still have plenty of juice at the end of the day. That's with the graphics maxed out full brightness also, and I play cod mobile at maxed out game settings for hours and it still lasts forever. Also the super fast charging is a plus! :)

Yes, I am having the same exact problem. I also had the same thing on my Z flip, Z Fold and Z Fold 2. All Z phones started having the issues with the Android 11 update. The S21 Ultra came with Android 11 but started having battery problems after about a week. I am getting 2 days of STANDBY and 1 day of moderate use, when I first got the phone I got 1.5-2 days of moderate and 1 full day 8+ hours of heavy use.

[@TheZhongguang]

I have the exact the same issue as you. Just got a new phone 4 days ago and in average 4 hours on screen time. I am not quite sure how these influencers for phones says they can get 8 hours more on screen time. My phone is clearly faulty!!! Thanks for your honesty sharing 👍

@@jashidvk8759 no really, draining like F***. I returned it and exchanged to iPhone pro instead. I was really disappointed, especially, I felt like I was cheated by all these phone influencers on KZbin to make that deduction to buy that phone. Don’t get me wrong, it was a great phone, it looks premium, but the 🔋 battery is the killer.

[@khadka98]

Same here. I got the phone jan 28 in USA. I was having 3-4 hours of SOT. Dark mode, adaptive battery, 120hz adaptive refresh rates, almost all the apps are in sleep mode. I also had the heating issue while using camera and light use. I sent the device for the repair (as return process was complicate because of trade-in and $250 preorder cedit issue). Samsung repair said it is not a hardware issue and their February patch is supposed to fix it and shipped the device back. I updated the phone and the battery problem is still there. I hardly get 4 hr SOT. I use most of the time listening to youtube in background over buds pro, facebook, reddit, amazon,webull etc. I don't even play games. Carrier is T-mobile (may be it is the issue but it shows full bars of 5G almost all the time). The phone also heats very fast. I don't know what to do as the phone has already passed 14 days of return period.

[@TheMrreese24]

I can't even begin to kill this battery, more like 6+ over 48hrs. The days I taxed it to see what results I would get gave me 7 1/2 to 8+, I'm amazed, knew it would be good but not this good. 512 Snap model 2 weeks usage. Heavy KZbin, slight gaming, heavy camera usage, and the norm, chrome, notes, messaging, banking, network administration, and document operations

I feel like you may have a defective unit. See what you can do to get a replacement. I definitely don't have that experience. Right now I'm at over 3 hours of screen on time, 70 percent battery, and just over 13hrs used. I'll go all night and through til tomorrow night until I charge at bedtime. That's pretty much standard for my use, but mileage does vary quite a bit. On stock settings, mid resolution, 120hz adaptive, auto bright, etc etc. Hope you get it resolved 👍

[@LucidPreditor]

The biggest killer of your battery is irregular charging. You can even restore a battery's last if you simple start only charging it once it has completely run down, and letting it charge completely.

[@TrollsEverywhere]

I don't have this problem even after updating. I'm loving how the battery lasts for more than 24hrs and it still has juice left. I'm on exynos variant btw. I assume you still have your warranty, you should get a replacement.

[@investfoxy]

It really depends on how much and what you use. What is your screen on time?

[@Mikenif]

Could be carrier related. Maybe weak signal causes the phone to constantly search for a better signal

I have the Samsung Galaxy S21 Ultra in Phatom Black and Silver (pictures on my community tab) the battery life on this phone is awesome. Not sure how many apps you have running in the background.

Most new phones have initial issues until they get a fair amount of software updates. I would expect the battery life issue to be resolved soon. It's got to be a software issue.

For me, the biggest drain on my battery is the SIM card. When I got my s21 ultra, I upgraded from iPhone 6s, and the battery in the 6s would die in about 30 min so I pretty much always had to plug it in. After taking the SIM card out however, my iPhone 6s stayed on for 6 hours before needing to be charged. I didn’t realize how much cellular murdered phone battery. So now I keep my SIM card in my old phone When I’m at home, and if I go out for an extended period of time I’ll put the sim in my s21. No point wearing down the battery in a 1200$ phone unless I have to.

Same here. It's terrible. First two weeks was okay, then battery life literally halved over night. I didn't install any new apps, didn't change any settings. I also noticed the first 10-20% seem to go slow, aftet than it just drops like a rock, like 1% per minute... I think i see the same in the video here. Contacted Samsung they said it depends on how i use the device, i told them nothing changed, they insist it is the only possibility.

Glad I'm not going crazy. I only get 6 to 6.5hours screen on time. I'm using WiFi only, dark mode, low brightness and have put 95% of my apps into deep sleep.

I don’t know what your talking about because last years Samsung galaxy S20 ultra lasted 90 hours in battery life in our last test and with the s21 ultra the phone lasted 108 in 120 hertz and 130 hours with 60 hertz so the battery life improved drastically

Okay but hold on, you had 12 hours of use off a charger with 6+ sot. And then you had 18 hours of use off a charger with 3+ sot. That's still really good imo. You might have apps running in the background. IDK personally battery life has been great for me. 1440p, adaptive display, with dark mode only at night. Gets me a full day use from morning to night. With 1080p, adaptive display, dark mode all day, gets me almost 2 days. More like a day and a half. But still great battery imo.

[@ricktodd3808]

I've had mine for a month now, no problem at all with battery. You need to contact Samsung.

[@artivideobup8743]

Hi TechOdyssey, I have exact the same problem. The SOT was at the start more than 7 hours (which not exceptional to be honest) but now after almost 2 weeks and a software update the SOT dropped to barely 4 hours (no wifi, no NFC, no bluetooth, no location, 120 Hz and battery save off and just some mailing, sms, webbrowsing and radio listening via earbuds thus lite use of the phone). I live in The Netherlands and have the exynos 2100 processor (unfortunately). I am in contact with Samsung about this issue. I can exchange the phone but I guess it will not help. I forwarded your video to them and asked them if the Samsung developers to look at it so they can see I am not the only one who has this problem. I will keep you informed what their reaction is what. Geat video of you by the way :-).

S21ultra 5G, 11 months old,the phone developed screen burn. 1/3 white the rest a see through pinkish. Very light but from experience it will get worse. Also for me it's the worst phone for battery life. Constantly needing to charge. At night I set it on table with screen off battery at 80-100% by morning I have to charge it. Seems to drain whether using or not. I had a note 9 prior and hands down it was 100% better than this very expensive upgrade. Regret the purchase.

[@chrishoyt3032]

I've noticed on my S10+ that this happened a few times. Most time Software updates fix the issue. I've also noticed that some app updates cause battery drain. Like its optimized on update and the next its broken and draining the battery. The other issue is browser tabs. I actually was told from Samsung the more tabs that are open in your web browser the more it will drain your phone battery. Crazy but when I closed all of them my battery life vastly improved. It could be a mix of things...if it was more wide spread i would be worried...but it seems its pretty isolated.

My battery life dropped off and i literally carry an extra power source now... plus at 4 months... yesterday i got a black screen and can not reset.... despite Samsung and Best Buy warranty i have to send the phone out and go 2 weeks without... i am beside myself with angst... it may be due to using fast charge with a 3rd party charging cord or its defective... (ironic since it came without a charger and charging cord).... if this had been my I phone i would have had to go to the store... but i would have left with another phone if they could not fix it at a 4 month time frame....

[@sc9433]

Try to disable 5g completely to see if it helps. I think ur phone is trying too hard to search for 5g in the background. This always happens to phones when new radio tech is at its initial implementation stage. 5g is not stable enough to be left on auto connect.

I just got my s21 after upgrading from my s9+ on 12/31/2021. I use dark mode and other battery life savers online says plus using airplane mode when i am not on it. I have to say when I first brought the phone I charged it up and it said 2 hours 25%. Well it did last for 10 hours. But after I fully charged it and turned it on it now says 1 day, 5 hours so I fully charged it on 12/31/2021 and left it off until 1/1/2022 and it said 100% 18 hours. Well today 1/2022 8:25pm New York time zone (eastern time) it says 7 hours, 59 minutes 25%. I haven’t charged it since 12/31/2021. So I am getting really good battery life. I bet most people uses their s21 all day with the screen on every minute. I am a light user don’t have many games downloaded so I guess I am just lucky. I hope Samsung will fix this issue soon because It would suck if it doesn’t.
