It happens to everyone, no matter what kind of make or model of device you own: as time wears on, your device starts to slow down and lag. It may be because youve downloaded power hungry apps or it may be because your cache has filled up to the brim. Regardless, its annoying and while sometimes a quick reboot will temporarily solve the issue, were delving a little bit further into some of the mains causes and solutions to these issues.
Clogged Memory
When you start to reach the limit on the SD card on your device, should you have one, youll notice that your device starts to slow down. If youre showing signs of lag on your device and youre using at least 80% of your storage capacity on your SD card, it might be time to go through your storage and do some cleansing.
With SD Cleaner, or a similar app, itll log all the unnecessary files on your SD card that you can trash without any complications, mostly cached files and other miscellaneous files that will help clear up some space. However, always be careful when youre deleting files and make sure youre not deleting something important.
Clear the cache
Yeah, it seems super simple, but sometimes we forget that apps start to cache more and more data as time goes on. Thankfully, you can go through and delete the cache yourself manually by heading to Settings > Apps and selecting a particular app and then hitting the Clear Cache button. However, if youve got an abundance of apps, this will soon become really cumbersome and time consuming.

If youre looking for a quicker method, you can grab an app like App Cache Cleaner, which will do all the work for you with a few taps on your device. Itll list all the apps that currently have cached data stored on your device and then you can pick and choose which ones you want to clear, or do it all in one fell swoop.
