If you have an iPhone with a swollen battery, there are a few things you can do to help it go away. First, try to discharge the battery as much as possible. This will help reduce the swelling and make the battery easier to remove. If that doesn’t work, try using a plunger or vacuum cleaner to suck out any excess liquid from the battery. Finally, if all of these methods don’t work, you may need to get a new iPhone battery.
