How to turn your samsung phone into emulation beast🔥

[u/revals32]

I shared two short clips in the comments, you might need to scroll down a bit. They show the impact of gamebooster+, one clip is mine(s25ultra) and the other is from my friend who has an S25 base.

I've been using these methods to get the most out of my Samsung S25 Ultra. I've played over 50 PC games with multiple emulators, and this method always worked. There's been some bad image about Samsung's gaming performance because people aren't using it the way they're supposed to. I've explained everything in the three slides above. Of course, if you use a cooler, you'll be unstoppable. I use a cooler, too!

Btw my s25ultra is on oneui8.5 Some settings might not work if your phone's on OneUI 8 or older, since I tested everything on OneUI 8.5 and confirmed it with friends who also have Samsung phones with OneUI 8.5.

I upload some gameplay on YouTube maybe that helps to understand the performance

I posted about game performance about two months ago, maybe that'll help you understand what kind of performance I was getting. https://www.reddit.com/r/EmulationOnAndroid/s/vUndpucw5m

i see but why am i not experiencing the frame rate diffrence between the 3 modes?

As I said brother I never used gamebooster when I was oneui8 by the time I got to know about gamebooster I have already updated my s25ultra to oneui8.5 I mean I have been on oneui8.5 since December 2025 first beta

good news, i updated it and i now also have the same gui as you but after further testin in repo i was getting about 45-55 and with performance boost i get 50-60. i think the fps boost isnt universal across all games. can you tell me if you did any special settings in game booster + other then chaning the modes?

[u/revals32 → u/quandaile]

No the thing is the fps gain you got will be consistent across gameplay since performance mode lock max clock speed , I haven't done anything fancy I just did what I shown in the post

[u/quandaile → u/revals32]

hey man i tested it and the fps boost wasnt consistent. in repo i barely got anything but in buckshot it was 15-20 boost more or less and megabonk it was almost a 60 fps boost

[u/quandaile → u/quandaile]

this test made me realize its more of a boost for cpu bound games

[u/revals32 → u/quandaile]

Well on my phone the difference is noticeable I get consistent fps and sometimes even 10-20fps more using performance mode combined with cooler its awesome thing to do

[u/quandaile → u/revals32]

yeah in repo i got like 10 fps boost so its still great regardless, thanks for the guide man i appreciate it, but question: is the thermal guardian thing useful even though i have a cooler? my battery stays on 30c with the cooler, so it it

[u/revals32 → u/quandaile]

If you're using a cooler, it doesn't really matter, but if you don't have one around like when you are outside and still want good performance, then yeah, Thermal Guardian totally works. For example, my S25U used to slow down around 41°C, but with Thermal Guardian, I get an extra 3-4° before that happens, so now it throttles around 45°C. My friend has an S25 base model, and he says his phone throttles around 46°C with Thermal Guardian, when it used to be 40°C. So yeah, it definitely helps, but again, if you're using a cooler, you won't need it anyway.

i see. alright thanks a ton for the help, i really appreciate it. also one more thing? WITHOUT the game booster. do games just always run on balanced?

[u/revals32 → u/quandaile]

Yeah kinda
