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 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.
Mike has a Motorola G4 and he wants to know if it's best for his battery to keep the phone plugged in whenever possible. There's been articles that claim it's best to do it differently, though. Leo says there's a lot of lore about lithium ion batteries, and Leo isn't even convinced that we understand how they really work. Leo gets his information from BatteryUniversity.com.
Owning a smartphone can often be a balancing act of usage and power conservation. If you're noticing that your phone is draining a lot quicker than usual, however, there is a way you can easily find the culprit. iOS and Android both offer statistics on what apps are using up your battery.
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.
Apple's Smart Battery Case for iPhone 6s is made from soft silicon, and has a lump on the back of it which houses the extra battery. It's not inexpensive, at $99, and you can actually get a better battery case for considerably less from third party manufacturers.
Joe has a Nexus 7 tablet and is worried about what will happen when the battery wears out. Leo says that the Nexus 7 can be opened and the battery can replaced. There's an article on. iFixIt showing how to do it. Joe is lucky because many mobile devices, like the iPad and iPhone, are designed so users can't replace that battery.
It's most likely because his phone is seeking for a cell signal while on the cruise, and since there isn't signal around, it will drain the battery faster. He should turn off his cell data or go into airplane mode and that'll preserve his battery power.
