Sofirn IF25a Flashlight: Brighter on Samsung 30T?

In this video, I test a Samsung 30T in my Sofirn IF25a to see if it produces more lumens.

Some reviews find that using a high drain cell like a 30T/40T can increase the lumen count up to 4200+ lumens in the IF25a. I used a simple lux app on my phone and the ceiling bounce test.

Test results: no significant difference in brightness.

I wonder if the cell included with the IF25a is already a high drain one (Lishen LR2170LA). I don't have any way of measuring the total lumen output of the light but it's apparent that the output across the two cells was similar.

What do you guys think? Am I missing anything? Let me know in the comments below.
