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 @nocteb@feddit.org 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 @tal@lemmy.today !
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+.
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.
Yeah, most just run a Android with reader-centric launcher and some of the Kobo devices have even LineageOS support. But like stated; they are barely powerful enough to run the launcher fluidly. And battery life sucks for a E-reader. Honestly, nowadays i would go with a Tablet and/or a PocketBook; they at least run a optimized Linux.
About my setup: all animations disabled in developer options, launcher inkOS, apps like Kotatau, Myne, Librery and Book Reader from F-Droid Classic. And Cromite with the setting to display a context menu on link, for those old.reddit stories.
I’ve gone with “Performancr Tweaker” from apkmirror now, this helps a bit, have Magisk anyway.
Cool! I had little to now 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…
