CyanogenMod is an aftermarket firmware for a number of cell phones based on the open-source Android operating system. It offers features not found in the official Android based firmwares of vendors of these cell phones. CyanogenMod also known as one of the fastest Android ROMs available. For many of us with older devices though, it’s not exactly speedy unless you make some tweaks to it. I run a htc desire hd with Cyanogen 7.2.
Here are a few changes I made to my dhd that made it super fast like it was a new phone.
1# Overclock the CPU
Take advantage of the capabilities that comes with rooting your device. Go under Settings > CyanogenMod settings > Performance > CPU settings and do the following:
Select CPU settings and set Max CPU frequency to a higher setting. I personally go with the highest setting you can choose. You may need to research what setting is recommended for your device. This may reduce the life of your hardware, but it’s totally worth it. Set Available governors to Performance. Check Set on boot.
2# Optimize ADW Launcher
The included ADW Launcher will run extremely slow on older devices if left to its default settings. Make some changes under Settings > ADWLauncher:
Select Drawer settings and uncheck Animated Drawer and Fade app labels. This will save resources and enable the launcher to load faster.
3# ADW drawer settings
Select System Preferences and uncheck Wallpaper Hack. Also under System Preferences, go to Scrollng cache and set it to Low quality.
If your device is still slow after the changes above, you may also want to do the following:
Under Settings > CyanogenMod settings > Performance, check Lock home in memory. Also under Settings > CyanogenMod settings > Performance uncheck Enable surface dithering.
Cyanogenmod performance settings
Uninstall unused apps. Move apps to the SD card. Delete widgets from the Home screen.
Restart your device and it should be flying now, but battery life will be lower.
