Sometimes, it can feel like there are few things worse than an iPhone or Android that suddenly begins slowing down on you.
If your smartphone has been running slower than usual, it doesn’t necessarily mean that it’s malfunctioning. In fact, certain apps could be to blame. Many apps continue working in the background even when you’re not using them, taking up resources and affecting your phone’s performance. Tech experts say a few common apps can use more power and memory than you might realize. Read more about two of them below.

3. Voice Memos
Some people can't imagine using their iPhone without their Voice Memos app, as they might use it for note-taking, rehearsing something, submitting recordings, etc. However, there are also a large number of iPhone users who don't ever really use it, and any old recordings sitting in the hardly-used app take up more space than you might imagine.
People are surprised by voice memos because they appear to be innocuous," says tech pro Ankush Chowdhury. "However, I've come across phones that have hours of unintentional recordings from pocket use. About 30 MB is needed for each hour of audio, and some customers had 20+ hours saved without realizing it."
