How to improve Android’s Performance
What is performance ?
How well is the Android phone doing the work it is supposed to do? Performance in computing is the amount of work accomplished by a system. Depending on the context,
it generally means
- How fast system responds to given work.
- Rate of processing work or operation.
- Rate of data transmissions.
It is difficult to upgrade CPU of Android device after purchase, so here are some ways we can improve its performance.
- Reduce load on system
Load is a measure of the amount of computational work a system performs, on any device there are many apps and processes running in background, most of them are important and some are not.
Stop unnecessary apps and processes from background, that will reduce load on system and improve its performance.
- You can see running apps from Settings→Apps
- In case if you can not stop any app or process, there is another option. Go to settings →About phone→build number now tap 7 times on build number, it will enable developer option in settings, now press back and go to Developer option→ Processes
you will see the processes running in the background. Stop unnecessary processes.
Alert : Do not stop any system process, it may lead to unexpected system behaviour and you may need to restart the device.
- Remove live wallpaper
Live wallpapers put extra load on system, every time we go to home screen live wallpaper need to run by CPU, so removing live wallpaper reduces load on CPU thus improves performance.
- Remove/disable bloatware
Manufacturers and carriers often load Android phones with their own apps. If you don’t use them, they just clutter your system. Bloatware is often commercial software that is preinstalled on a device by the manufacturer. By removing these apps, you'll be able to improve your phone's performance. Go to Settings→ Apps → {App name} → disable/ uninstall to disable or uninstall bloatware.
- Keep fewer widgets
Widgets are active components, they have periodic update time and they update its contents after specified time. Having too many widget on home screen puts extra load on system. especially if it is weather, news etc type widget. So removing widgets improves Androids performance.
- Use high speed memory card
If you are using microSD memory card make sure it has high speed rating like Class 10 , UHS or V class.
class ratings measure the minimum sustained speed required for recording an even rate of video onto the card.
The current SDHC specification defines Class 2, 4, 6, 8 and 10 as follows:
you will see the processes running in the background. Stop unnecessary processes.
