EDIT3: this is NOT an overclock! Manually setting a scaling governor does not forcibly increase the intended frequency range of the CPU clock! Setting the scaling governor has more to do with performance management. In my case, setting it to “performance”, it simply forces the cpu to always run at the maximum frequency as designed by the manufacturer. Further reading here and here. Thank you @[email protected] for the reminder!

EDIT2: the tablet is rooted with Magisk ( https://topjohnwu.github.io/Magisk/install.html ) and Termux is running with superuser privileges granted through Magisk. The below command was issued after su - ing into a root shell. “performance” was echo ed into all available /sys/devices/system/cpu/cpufreq/.../scaling_governors, meaning, there are several subdirectories called policy[0...] in which the scaling_governor files reside.

EDIT: echo ing “performance” to /sys/devices/system/cpu/cpufreq/policy0/scaling_governor seems to have maxed out the cpu clockspeed! Now the tablet is snappy as hell! It’ll be interesting to see how battery drain and heat are affected by this. Thank you @[email protected] !

Say, by sending some value to something inside /sys/.../cpu or the likes. I have already aggressively debloated the tablet, but I like to experiment and I am not afraid to destroy the tablet since I bought it for 150 bucks at sale. Or pehaps there is some Magisk module that can do this?

The tablet is a Samsung Galaxy A9+.

    Thanks, i’ll try this on my anemic E-reader (Kobo Boox Leaf). It’s a bit painful to run, barely fast enough to not timeout Kotatsu (Manga).

    But needs to be done each reboot.

      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.
