FAQ

Q: Do iPhones Last Longer Than Android Smartphones?

In many cases, iPhones tend to last longer than Android phones. Apple iPhones offer better durability and longer battery life. However, in comparison, some Android phones like the Samsung Galaxy S20 Ultra 5G boast compelling features which cost more battery power.

Q: What Kills a Phone Battery?

Everyday use is the main culprit of draining a battery. The use of apps that update regularly or run in the background will always be using your phone's battery. Most smartphones allow you to check battery usage in the settings to monitor which apps are draining your battery the most.

The chemical and electrical components also dictate battery performance. Over time, and with regular charging, these degrade, so your smartphone's battery life will reduce over time.

Q: Can I Repair My Phone's Battery?

If your smartphone's battery fails, it is unlikely that you can repair it yourself. Very few phones on the market have removable covers allowing access to the battery compartment. Even fewer offer you the option to easily replace the battery. Unfortunately, this will need to be done by a professional or returned to the manufacturer in most cases.
