r/samsung on Reddit: The Samsung S21 processor is the best Exynos in Samsung history
February 14, 2025 -

I bought an s21 in 2024, the motherboard of my s9 was burned, the exynos of my s9 was heating up, and the battery didn't last long, so for the purchase of a new samsung I was afraid about the samsung chips, so much so that I had aimed at the s20 fe with the snapdragon, but I decided to give a chance to the exynos of the s21, the reviews spoke well of it.

Guys, it's a masterpiece, it never heats up, super fast, with 120 hz activated the s21 can easily hold up in 2025 with phones released now, I think samsung hit the mark that time..

Funny that the s22 has returned to having a mediocre exynos, Samsung is really strange what do you think? Do you agree?

I miss the s9 screen though, that resolution was crazy

October 31, 2020 - ... 68°C core temperature is hot for a flagship CPU? My S21U with the Snapdragon 888 hits 88°C while running Geekbench, could be an issue of the benchmarks themselves, if they read out a wrong sensor.

February 8, 2022 -

I don't think S21 Ultra Exynos can upgrade it's CPU to a better Snapdragon though. I would like to upgrade the S21 Ultra phone without getting the S22 Ultra platform which now operates in a lesser of a phone's component space that was taken up by a pen holder.

3 weeks ago - The processor and thermals on that phone are crap, DO NOT get a S21U or S22U those have the horribly efficient chip. Get a S23U and up ... I used my s21 ultra since 2021 until last month when it fell and screen damaged. Camera had alot of glare reflecting off the light compared to newer phones.

The number of cameras has also gone up but I'm struggling to understand what the new one does. Could overall be a decent improvement. ... The main one is the same camera essentially.

r/S21Ultra on Reddit: Are newer devices really that much better than the S21 Ultra?
March 3, 2025 -

My wife has an S22 Ultra. It's alright. I don't really think it's all that worthwhile of a device to upgrade if you already have an S21U, unless you get a really good deal.

I had the chance to try out an S23U recently.. And honestly, I wasn't impressed that much. If anything, it almost seemed like a downgrade, particularly in the camera department. Everything seemed to be off colored and grainy. My wife seemed to think so as well. Tried different settings... Nothing seemed to improve it much.

My wife's device, the S22u 256gb with 12gb of RAM, is incredibly laggy. I've never had this problem with the S21 Ultra.

That makes me beg the question... Are these newer devices really worth upgrading to from the S21 Ultra? There seems to be so many issues with newer devices.

It might be possible for me to get hands on an S21 Ultra sealed pack for approx 320 usd (29k inr). You think this is a good deal? And does it makes sense spending this on a phone which effectively does not have any OS updates coming? I have always wanted to get an Ultra but never got around to doing it, and this might be an opportunity. I'm checking if I can get a similar deal for s22 ultra, but it seems unlikely.

Let me know your thoughts please.

January 5, 2024 -

I have a Samsung M62 an intermediate and I'm thinking of buying a S22 ultra or a S21 ultra I've always had the dream of having an ultra but I was watching video analysis of comparisons between phones and I saw that in the comparisons between the s21 ultra vs iPhone vs Pixel and people said that the s21U is better in the cameras too but when I saw S22 ultra vs iPhone vs Pixel people said that they were all similar phones great phones and that there wasn't that much difference few comments saying that the S22 ultra is better, for me I want a cell phone with a good camera a battery that lasts at least a day Or that I only charge at night, I don't use games much more social media and streaming, I plan to use the New phone for about 2 years at least.

What are your thoughts? Do you think Is It worth It to pay more for an S22U ?

I've posted this list a few times on Reddit and don't really wanna look like a spammer but people keep asking this, so here you go: The S21 Ultra is better than the S22 Ultra at most stuff, and the same in a lot of stuff. Here's the list: Larger 3x telephoto sensor size (1/3.24" vs 1/3.52”) and with a slightly higher mm focal length meaning slightly higher zoom (72mm vs 70mm) Larger 10x periscope sensor size (1/3.24” vs 1/3.52”) and with a higher mm focal length meaning higher zoom (240mm vs 230mm) Same size 108MP 1/1.33” main wide sensor Same 12MP 1/2.55” ultrawide sensor Higher PPI display density (515 vs 500) Taller 20:9 aspect ratio preferred by some people 12GB RAM in base 128GB S21 Ultra vs 8GB in 128GB S22 Ultra Up to 16GB RAM in high storage S21 Ultra vs 12GB max on S22 Ultra Louder stereo speakers with better sound on S21 Ultra Superior haptic feedback motor for tighter vibration response on S21 Ultra (Also the main reason MKBHD used the S21 Ultra throughout 2022 instead of the S22 Ultra) Same 5000 mAh battery capacity, but better real world battery life on S21 Ultra because of the chip's efficiency, which I go deeper into down the list Better design on the S21 Ultra (personal opinion lol) Pros for S22 Ultra: Pretty much the same durability with Gorilla Glass Victus on S21 Ultra and Victus+ on S22 Ultra (still scratches at a level 6 with deeper grooves at a level 7) Slightly more brightness on S22 Ultra but barely noticeable even in sunny days outside (1500 nits on S21 Ultra vs 1750 nits on S22 Ultra), also, you need to swipe to the quick settings, tap the 3 dots on the brightness slider and turn on Extra Brightness if you really want more brightness, which will obviously consume more battery and heat up the phone, which is a problem since the chip also has overheating issues. Ever so slightly faster Snapdragon 8 Gen 1 processor in S22 Ultra in Snapdragon regions and Exynos 2200 in benchmarks, but no noticeable real world performance difference, even in heavy games. Also, multiple users have experience more overheating and overall less efficiency on both processors on the S22 Ultra than on the S21 Ultra, with it being the biggest problem with the S22U, the chips are horrible, both Exynos and Snapdragon. S-Pen support on both devices, but S22 Ultra is capable of storing the S-Pen inside the chassis as all previous note phones, and has slightly shorter latency. (If you like the Spen in the phone I guess) And I also have 2 YouTube videos explaining why the camera is better on the S21 Ultra than on the S22 Ultra but it's in Portuguese lol. You don't really need to understand Portuguese, just by looking at the pictures shown in the video you will see the difference, you don't need to watch the videos since it is just a guy going over the pictures on the bottom link: https://youtu.be/wTYaVBLdMvc https://youtu.be/3Yy8hZB6V-g The videos just go over these comparisons on this website between the cameras of the S22 Ultra, S21 Ultra and Note 20 Ultra (look at the edges of the pictures, especially on 1x, that's the main issue with the S22 Ultra, likely due to making the lenses thinner): https://m.gsmarena.com/samsung_galaxy_s22_ultra-review-2382p8.php And yeah that's it. The S21 Ultra is great and better than the S22 Ultra.

S21u has a better form factor but the S22u cameras are significantly better. I compared my old s21u to a friends s22u and his results were better.

I have an S10 right now thar works perfectly but feel I should upgrade before issues arise. Do not care about the latest features or acquiring status by having the latest cell phone.

Is it a bad move to purchase a galaxy s21 right now in April 2024 It's unlocked. From backpage.com 168 bucks

Is this the right move?

Samsung beats apple in my opinion. Unless you like iphone ecosystem then Sammy is the better phone in all specs that matter. Iphone really only has a slightly faster processor st this point. ... I really love my Note 20 Ultra, but this is some serious competition.

r/S21Ultra on Reddit: Suggest a android as good as samsung s21 ultra but not samsung.
May 26, 2024 -

On the end of May my s21 ultra (exynos) had a big update, and ever since it has freezed unexpectedly and afterwards had multiple reboots. I had it examined in a local phone service, but they found nothing. I have had enough of this, once it stopped working in a middle of a super busy night as I was planning the night with my friends.

Before I was a Samsung ultra fan because my previous s20 ultra had proven to be a reliable, smooth and fast phone. The issue I have encountered now has shaped my thoughts, and I no loger want to have anything to do with Samsung.

Please suggest a android phone you find as good as Samsung Ultra, but more reliable. In the best scenario also as good camera, but that's not the main thing. I have positive experiences with Xiaomi, but I was thinking about One Plus although I haven't had one. Thank you!

r/samsung on Reddit: My long-term review of Samsung S21 Ultra. Which new phone would be better for my usage?
October 9, 2024 -

I got my Samsung Galaxy S21 Ultra 512 GB with 16 GB RAM back in October 2021, and since then, I’ve truly made the most of it! 📱

Photo/Video Backup

With 76,000 - 76,500 photos and videos (excluding screenshots and WhatsApp images), it’s time for another backup on my HDD, as my Google Photos storage is maxed out. 😅 I back up twice a year, and considering an average of 70k photos per backup, that’s around 140k photos per year. Over the past 3 years, I’ve easily accumulated around 420k photos/videos. Capturing memories is definitely my forte! 📸✨

Battery Life 🔋

Flagship phones come with bigger batteries, and mine’s no exception! I charge it to 100% in the morning, and even with heavy usage, it lasts until evening. With moderate use, it powers through till night. It’s like having a mini power station in my pocket! 💪

Multi-Window Apps 💻📲

I’m a multitasking pro—I use two apps almost every day, like Mail and WhatsApp simultaneously. The split-screen feature has become a daily companion!

Image/Text Conversion

From day one, I’ve used the feature to capture and convert images or screenshots into text. This has made note-taking and information extraction a breeze! 📝🔍

Reverse Wireless Charging

This is where my phone truly stands out! 🔄 People are always amazed when I let them place their iPhones on my phone’s back to give them that much-needed 10% charge boost. 😅 I’ve saved the day for countless friends and strangers with this nifty feature!

Telephoto Lens

I’ve captured thousands of photos of the Moon, and I’m still not done. That 100x zoom lens is simply phenomenal! 🌕📷

8K/4K Video Recording 🎥

Whether it’s 8K or 4K, I’ve pushed the limits with the video capabilities. The quality is insane, and I’ve loved every moment spent shooting high-definition videos.

Professional Photography

I’ve even used the 108MP main camera for professional car photography and pre-wedding photoshoots. The results? Stunning! 🚗💍📸

Durability

Despite being dropped countless times (I’ve lost count!), it only has a few minor scratches. Talk about resilience! 🔧💥

Bixby & Desktop Mode

With Bixby, my phone transforms into a desktop. I can access all my phone apps on my laptop seamlessly. It’s been a game-changer since day one! 💻🤖

Unique Features

Edge Panel, Good Lock, One-Hand Operation, S Pen support—I've explored A-Z of this device’s capabilities.

I’ve truly pushed this phone to its limits over the past 4 years. Whether it’s photography, multitasking, or unique features, I’ve used it all.

I guess that makes me the perfect flagship phone user 😅🫠 This phone was worth every penny! 💯

I am thinking about getting a new phone. Which phone would be best suitable for my usage? Thank you.

January 2, 2019 - As someone who likes good screen resolution, i still fell bad that samsung decides to give fhd only to non-ultra models ... The changes I like the most is the 5nm process and Wifi 6E. Although I will wait for its refinement in the Note Series. "1st generation" of anything is often plagued with bugs. ... Possibility is note series this year might not come. ... Other than the processor is the S21 better than the S20 at all?
