When should I replace my smartphone?

Smartphones typically have a two- to three-year lifespan. Many can last longer than that, but their operating systems begin to slow down and the battery life becomes weakened with age. When your phone is no longer functioning properly, you should either trade it in or purchase a new one so you can have a reliable phone.

How often should I charge my smartphone?

Smartphones should be charged when they have a battery percentage between 20 to 80 percent. When your smartphone is fully charged, you can remove it from the power source. Depending on the type of smartphone, you may be able to go for several hours or even days without charging your device. Your smartphone will give you an indicator of when it needs to be charged, and you can always consult the percentage on the device itself.

Does a smartphone need to be connected to WiFi to access the internet?

No. Your smartphone will operate fine without being connected to WiFi. You can access the internet by using your phone's cellular data; however, depending on your data plan, you may want to connect to WiFi in order to reduce your bill.
