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+.
Interesting. I’m sure heat and battery life are noticeably affected. If not very noticeably, I think significantly anyhow I recently got some Galaxy Note 10" 2014 units, and I am trying to get the very best out of it. I hadn’t even known about them. The early Galaxy Note phones were terrific, but still a phone size. Then there are the Galaxy Tab models which basically deals with the size issue but not really designed specifically for what I wanted. This thing is just a very enlarged Note 4. On a couple of them, I put TWRP and custom ROM, while on one of them I kept the stock ROM with its last update, bringing it to Android 5.x. It runs the old school Adobe PS Touch, Snapseed, Sketchbook, S-Note, and a handful of other graphics apps. They all run beautifully and it’s my almost-perfect art device. Rooted and debloated, of course. I’m gonna see how these modified units do on eBay.
I think my long-winded rambling point is that rather than kill your battery and possibly cause severe wear on your device, maybe find one that can use a custom ROM, or at least Root and optimizing by shutting off tons of bloat.
