This meant taking part in Fortnite, Minecraft, Zenless Zone Zero, and even informal video games was at all times a pleasing expertise and did not undergo from the discomfort that comes with a scorching cellphone.

As you may see from the chart above, utilizing Aulumu’s Frosted Glow case — the marginally heftier case pictured on the high of this text — precipitated the cellphone to succeed in 107 levels Fahrenheit (41 levels Celcius).

Within the Galaxy S26 Extremely’s case, Samsung appears to begin closely throttling efficiency round 42 C primarily based on my testing, so conserving it under that quantity is extraordinarily vital.
I ran a number of benchmarks utilizing 3DMark’s built-in stress assessments, which run 20-minute ray-traced 3D benchmarks to push the Galaxy S26 Extremely to its absolute restrict. Whereas the Aulumu Aramid fiber case solely stored the cellphone a number of levels cooler throughout the stress take a look at, the efficiency distinction was downright staggering.

On common, I discovered the Galaxy S26 Extremely scored round 900 factors on this benchmark when utilizing a conventional cellphone case (just like the Aulumu Frosted Glow case).

For those who’re a cell gamer, you may know that the 20-30 minute mark is normally when a cellphone hits its lowest efficiency mark and sometimes would not get well from that pace till you place it down for some time. With the Aulumu Aramid fiber case, that pace did not drop as a lot, and it stayed constantly sooner because the cellphone might stay cooler.
I usually favor Aramid fiber instances for his or her minimalist construct, however Aulumu has given me a cause to decide on its ultra-slim instances over a few of my different favourite manufacturers, because it not solely appears to be like and feels higher than a traditional case but additionally helps the cellphone carry out higher beneath stress.
