Using Sketchy Accessories
One of the worst things you can do to your iPhone is to use cheap, off-brand or non-certified accessories — like chargers, cables or docks. These accessories are often lower-quality and will offer subpar charging speeds or performance.
But they can also be dangerous to you or your iPhone. Cheap wireless chargers can burn out your battery quicker, while shoddy cables or power bricks can cause overheating or fires. You don’t necessarily have to opt for a first-party Apple accessory, but we highly recommend going for MFi-certified accessories with good reputations.
