Sooner or later, it happens to almost every device. Over time, it just isn’t as fast and responsive as it was the day you bought it.

There are various reasons for this, but unlike an old car that starts to deteriorate over time, chances are that the device itself is still in good condition. With the exception of the battery on a phone or the hard drive on a PC, most components of both phones and mobile devices are quite resilient under normal conditions. Batteries can degrade with time, and hard drives will eventually wear out, but from my experience, phone and PC hardware problems are rarely the reason devices start to slow down or act erratically.
