When Should You Replace Your Smartphone Battery?
The signs that a phone battery is wearing out, what battery health readings mean, and when replacement makes sense.
Packaging, build quality and verification checks that help you tell an original charger, cable or pair of earbuds from a counterfeit.
Counterfeit chargers and cables are often sold at a price close to the original, so price alone is not a reliable signal. A few careful checks before you buy can save your phone's battery and charging port from damage.
The most reliable check is the seller. Brand stores, authorised service centers and established retailers source stock through official distribution. If a listing is far cheaper than everywhere else, treat that as a warning, not a bargain.
Original packaging is printed sharply, with consistent fonts and colours. Look for:
Genuine adapters are usually dense and solid. Counterfeits are often lighter, with seams that are uneven or plastic that flexes when pressed. Pins should be straight, well-finished and firmly seated. Printed text on the body should be crisp and match the packaging.
Some brands offer serial-number or QR verification on their websites. Where available, use it. It takes a minute and is the strongest check you can do at home.
A counterfeit charger may work at first but charge slowly, run hot, or cause the phone to show a charging warning. If an accessory gets unusually hot, stop using it.
Chargers regulate the power going into your phone. A poorly built charger can damage the charging circuit or the battery, and those repairs cost far more than an original accessory.
If you are unsure about an accessory you already own, bring it in with your phone and we can take a look.
