S25 Ultra vs S24 Ultra vs iPhone 16 Pro Max - Heavy Workload Test (Speed, Battery & Thermals)

The S25 Ultra is here with the Snapdragon 8 Elite for Galaxy so, in this heavy workload test I will compare it against the S24 Ultra & the iPhone 16 Pro Max.

A18 Pro chip in the 16 Pro Max vs the Snapdragon 8Gen3 For Galaxy in the S24 Ultra vs Snapdragon 8 Elite for Galaxy in the S25 Ultra.

The test includes 4 heavy tasks that each flagship to run simultaneously for 30 minutes to see which one will survive and takes the win.

Funny how for S23 Ultra these tests were a piece of cake but 2 new generations are suffering

[IuGA]

it's funny how S23 ultra did finish this test compare to newer models

I'm happy with my iPhone 16 pro max, works great, I will wait a few years to upgrade, but I will change the case and get some accessories, any recs?

Based on your previous videos i think the s23 ultra is best of the ultra series

[hahahahahahahaha]

S23 Ultra retained the brightness to the end.
S23 Ultra domination

[JDX_]

Genuinely appreciate these types of videos!

[walterisawake]

Now this is a real-life performance test. Rather than just relying on Geekbench and AnTuTu, I prefer these videos. What a performance beast the 16 Pro Max is 🤯

[jonathanking]

S23, focus on performance
S24 and 25, focus on ai

I think it‘s quite interesting how much of an improvement the iPhone 16 Pro Max is compared to older models in this test 👀

Apple can go head to head with even some gaming phones which shows how far they are in terms of efficiency. Samsung does deserve credit for not blundering in performance like the last few years. It can now attain 60fps in many demanding games for much longer. I would love a retest in a few months as Samsung does push out updates.

Been waiting for this video with anticipation - thank you

[BigTimeVocals]

I'd love for the S23U to also be included in these videos! Also, results will probably change with the Day 1 Patch on the S25U (apparently a 24gb update💀). And it'll also be interesting to test the S24U again when One UI 7 drops, since it's been really disappointing with every version of 6.1 until now. Love these videos and your dedication💜

Can You Do same test with matching S25 ultra screen resolution same as iphone 16 pro max

The good thing that apple improving them phones .

[laithmalky]

[lulushishi]

Glad Apple is stepping it up with performance. Hope samsung starts improving instead of copying Apple year after year.

This is the reason I bought the 16 PM at the last moment in spite of being a Samsung lover all my life and planning to buy the S25U. Samsung failed to deliver and also disappointed majorly this year.

[mtbohana]

Can you do this test again when the Galaxy S25U Feb 7th software update releases? According to Samsung it's a huge update and will improve performance.

[denniszotomayor]

Please do the same test including S23 Ultra in January Software Update version, let see how it compares with S24 Ultra and S25 Ultra
