Take swelling iPhone batteries to the Apple Store ASAP!

If you have an iPhone battery swelling up and expanding, it's best to take the cell phone to your nearest Apple Store to get the battery replaced. The store may replace the battery for free since a bad battery can become a hazard (causing a phone to catch on fire or explode). Alternatively, an authorized Apple repair store could help fix the issue.

John from Gastonia, North Carolina

John is having an issue with his first-generation Apple Watch, where during a hot day during the summer, the whole face of the Apple Watch was becoming detached from the device. Leo says that's because of the lithium-ion battery within the watch, due to the heat. The battery can swell up due to age, defect, or heat, and eventually explode. Leo says that John might be able to take it into the Apple Store and get it replaced for free. But since it's a first-generation Apple Watch, Leo is not sure what Apple will do. But if John is friendly about it, Apple may replace it regardless.

Shelia from Chatsworth, CA

Shelia has a Kindle Fire tablet, but it doesn't hold a charge. Given the age of her tablet, Leo says that the battery is just worn out. Lithium ion batteries have a limited charging life, about 500 cycles. Once she's gone past that, she'll begin to see battery failure. She could try to contact Amazon and see if they can replace the battery. But she shouldn't spend a lot, as a new Kindle Fire is only $60.
