We all love the convenience of modern cellphones, but all those apps, photos, videos and games compete for a limited amount of room in which to operate.

Do you really use all those apps?

Take a long look at the apps you’ve downloaded, and decide which ones you use regularly and therefore need to keep. Delete the rest. Unused apps not only hog precious storage space, they also impact your battery life, as they are constantly restarting and running in the background without you even realizing it. You can always download an app again later if you discover you can’t live without it. But for now, get rid of the extras.

Learn to manage photos and videos.

Photos, and especially videos, chew up memory with each one you save. You also run the risk of losing the entire collection if something happens to your phone to wipe out its memory, or if it is lost or stolen.

Review your saved items frequently to make sure you’re not keeping too many duplicates. Perhaps most importantly, regularly back up your files to a computer, external hard drive, or cloud-based storage – then delete all (or most) of them from your phone.

Clean up after browsing.

When you surf the internet on your phone, each website stores a unique collection of images, videos, or text files required to display things like web pages and advertisements. These files makeup what’s called the phone’s cache memory, or cached data.

As they accumulate, you’ll start to notice web pages taking a lot longer to load, making your browsing experience much less enjoyable.

To avoid this, make it a habit to periodically clear your cache memory. While each Android phone or iPhone is slightly different, the general process will include going to the “Settings” menu on your phone, then locating your Storage, Apps, or Applications Manager menu. Cached data is usually stored here, clearly labeled. Follow the prompts to delete unwanted files.

Make your contacts count.

Your “Electronic Phone Book” can overflow with duplicate entries or just-plain unimportant contacts. The cost of all that extra data is not only time wasted scrolling through extraneous information; it’s also eating up memory you could use for more valuable things.

Review and organize your contacts regularly to make sure you have a well-organized and up-to-date list. Delete entries you won’t likely need again. And sync your contact list with your Apple or Google contacts to create a backup, just in case anything happens to your phone or its stored data.
