Cool! I had little to no knowledge on e-readers… Wanting to buy one, and realizing how expensive they are, is what made me go for the Galaxy Tab A9+. It was about 150 bucks, on sale. I don’t regret it.

I hope tweaking the scaling governor helps you some, but as I have stated in the various updates in the OP, it has its quirks…

I like to experiment

and it has an awfully bad CPU that lags from time to time, but first and foremost

Thank you for this insight! Before setting the scaling governor, I did some initial testing that showed exactly what you’re saying: whenever I switched windows, fired up another app, wrote to a file - really whatever I tried - the frequencies maxed out. Maybe, what felt marginally snappier was the result of the CPU not having to jump between frequencies? I have zero knowledge on how CPUs work with power… 😅

I had no idea e-readers can do manga 😱😍 maybe I should get one, after all 😁

probably needs to be done after reboot and probably drains battery more than otherwise, but I have not done any testing as of yet. I sat at a café and played around with it for two hours, during which I couldn’t really notice any difference in power draw since the battery capacity is huge. Keep checking the OP, since I might update after some testing.

Which resulted in what I was aiming for. There are other available scaling governors that yield different frequencies.

EDIT: I’m running stock Android rooted with Magisk. OneUI 7, Android 15, Kernel 5.4.249

I haven’t tried rebooting yet, but I’m pretty sure it resets on reboot. Also, my only evidence that it worked is what cpuinfo_cur_freq reports, and because of how Android seems to works with its virtual filesystems and Termux only being a virtual terminal, I’m actually unsure of how to measure the true frequencies in any other way. Here are two screenshots anyway. 1804800 is the maximum available frequency.

Thanks! I’ll go on and check if there is anything precompiled out there.
