Are you surprised at how quickly your iPhone’s battery is drained? Do you think your iPhone’s battery drains more quickly than it used to? Clients often express these concerns to me. In turn, I show them Scotty Loveless’ excellent article from mid-2014 about iOS Battery Life. It teaches you how to monitor your device’s battery and determine which apps are causing your iPhone or iPad’s battery to drain. It also offers a slew of tips to help reduce battery drain and suggests if you think you really have a problem with your iPhone’s battery to visit the Genius Bar to have them test the battery.
Scotty indicates that Apple’s Genius have a comprehensive battery life test that they can run on iPhone 5s and newer models. Apple also has an iPhone 5 Battery Replacement Program for a small subset of iPhone 5s sold between September 2012 and January 2013 that have defective batteries.
If you have experienced a gradual decrease in battery life over the 12 or 18 months that you’ve owned your iPhone or iPad then this might just be normal wear and tear. All rechargeable batteries have a limited lifespan and may eventually need to be replaced. A battery’s lifespan is measured in the number of charge/discharge cycles it can handle before it’s worn out. Apple states that iPhone batteries are “designed to retain up to 80% of its original capacity at 500 complete charge cycles.” If your battery is nearing the end of its lifespan, but you don’t want to replace your entire phone then you could have either JCD Repair or Apple replace the battery.
Take time to read Scotty’s article and follow his tips on changes you can make to reduce battery drain in your iPhone or iPad.
