Use chargers and cables that meet the device manufacturer's requirements or come from a reputable supplier. Check that a charger supports the type of charging your device expects, and do not rely on damaged, frayed, or unusually hot accessories. A connector that fits is not enough to guarantee that the charger and cable are appropriate for the device.
Charge devices on a firm surface where heat can dissipate. Soft bedding, clutter, and closed containers can trap heat around a phone, tablet, or battery pack. Keep liquids away from charging equipment and avoid pulling a plug out by its cable. If a device becomes unexpectedly hot, smells unusual, or shows visible battery damage, disconnect power when safe and stop using it.
Follow the manufacturer's guidance for long-term storage and charging. Modern devices manage many routine charging tasks automatically, so elaborate charging rituals are rarely necessary. Keep software current and inspect accessories periodically. When traveling, protect connectors from dust and bending, and use a power adapter suited to the local electrical supply. Sensible care cannot prevent every failure, but it can reduce avoidable strain and make problems easier to spot early.
Power Strips, Swollen Batteries and Everyday Warning Signs
Many homes now charge several devices from one spot, often a power strip on a desk or beside the bed. Use a strip that is designed for the load you plan to connect, avoid plugging one extension lead into another, and keep the strip where it is not buried under cushions, rugs or paperwork. Charging a phone and a pair of earbuds draws little power, but the same strip may also be feeding a laptop, a monitor and a lamp, so it is worth knowing what is connected rather than adding devices without thinking.
Recognising a battery that needs attention
Lithium-ion batteries usually give some warning before they become a real hazard. Signs to watch for include:
- A case that no longer sits flat, a screen that lifts at the edge, or a back panel that bulges
- A device that runs out of charge far faster than it used to, or shuts down at a reasonable percentage
- Hissing, crackling or a sweet chemical smell
- Heat during light use or while switched off
A swollen battery should not be pressed back into place, punctured or charged again. Move the device away from flammable materials if you can do so safely, and contact the manufacturer or a qualified repair service. Old or damaged batteries should go to a dedicated battery recycling point rather than household rubbish, where they can be crushed and catch fire.
Charging overnight and while unattended
Most phones and laptops stop drawing significant current once full, and many offer optimised or limited charging modes that hold the battery below 100% until shortly before you usually unplug. Turning these features on is an easy way to reduce long-term wear. Larger items such as e-bike and e-scooter batteries deserve more caution: charge them with the supplied or approved charger, in an area with a working smoke alarm, and preferably while someone is at home and awake.
Children, pets and shared spaces
Chewed cables are a common cause of damage, so route leads out of reach of pets and young children, and unplug chargers that are not in use in shared rooms. If you are reorganising a media corner around a new TV or soundbar, the same principles apply; our guide on choosing a 4K TV covers planning a tidy setup where cables and adapters have room to breathe.
