How to speed up and clean up your iPhone
We've shown you how to clean and disinfect your gadgets before and if you're busy optimizing the insides of your iPhone, you might as well clean up the outside too. This is especially important if you use a case because over time dust and dirt get trapped in-between the case and iPhone. The dust can end up scratching the back of your iPhone if you're not careful. If you have a rubber case you can clean it with a solution of water and Windex.
In general iPhones don't need a lot of maintenance, but hard drives fill up quickly and that's the biggest cause of problems further down the line. As always, when you're cleaning everything above don't forget that a good old hard reset (hold home button and power button until it restarts) can do wonders for your iPhone's speed.
