A few choice tweaks to your kernel settings can also extend the life of your battery Changing the clock speed is always about finding the right balance between power and battery life. Overclocking will likely require you to sacrifice a little of the latter.
Underclocking is the opposite: it involves reducing the speed of the processor in an attempt to extend your battery life.It isn’t a magic wand. Underclocking causes some tasks to take longer to complete, which offsets the benefits of having the processor using less power at its maximum level. Nevertheless, for some tasks it can be beneficial and switching the governor can have noticeable effects. As ever, the best approach is to experiment with settings to find ones that work for you. And don’t push things too far – if you set the processor clock speed too low it may not deliver enough speed for your apps to work.
1. Set up the app
In EX Kernel Manager, create a backup of your existing kernel settings. Open the sidebar and select Tools, followed by Kernel Backup. Tap the disk icon to create the backup and give it a recognisable name should you need to restore it someday.
2. Reduce the clock speed
Now go into the CPU settings. Underclocking is the same as overclocking, except in reverse. Try experimenting with lower maximum frequencies, so that your phone runs at a slightly slower speed, causing it to use less power. Just don’t overdo it!
3. Change the governor
You also need to adjust the governor settings. The obvious one to use is the Powersave governor, which locks the CPU to the lowest frequency. However, you might do better with the Performance governor, so that tasks will complete in the shortest possible time.
4. Test the changes
Exit the app and then test your changes. Open a few apps or games and run a few common tasks. It’s likely that you’ll notice the phone is a little slower, but if it’s too slow then you will need to tweak your changes. You want to find a balance between speed and batter.
5. Explore Powersave mode
The EX Kernel Manager also has a Powersave utility. This is activated by tapping the leaf icon at the very top of the app’s screen. This mode sets the processor to run at predefined levels and enables you to quickly reduce power consumption.
6. Tweak settings
To change the Powersave mode settings, tap the three-dot menu icon and choose Settings. You can set Powersave to activate automatically on a certain battery level or hit Advanced settings to reduce the CPU speed even further. Again, keep your changes small.
Enjoy Great New Powerd Life....
