Mobile phones and tablets

Mobile phones and tablets usage and safety

Mobile phones and tablets are in everyone’s home, pocket, and backpack, managing our daily routines both for work and leisure. But it’s important to ensure they are looked after properly.

There is now a vast range of choice for mobile phones and tablets, ranging from basic models to high-performance computing.

Smartphones are the most common, offering touchscreens, high-resolution cameras, and app ecosystems, while more basic budget-friendly phones focus on voice calls and SMS, with limited internet capabilities.

Some are designed for high-performance gaming with advanced processors, better cooling systems, and specialist software. 

Foldable phones come with flexible displays, and combine a smartphone and tablet experience. 

Tablets are primarily for media consumption, browsing, and entertainment, but you can also get hybrid models with detachable keyboards to serve as laptop replacements, and e-readers which are optimized for reading digital books with a long battery life.

Most phones and tablets use either the Android, Apple (iOS), or Windows operating systems (OS).

Key points

  • Read the manufacturer's instructions carefully and always follow them.
  • Protect your device from damage and don’t immerse it in water.
  • Do regular checks of the charger plug and socket-outlet for burn and scorch marks.
  • Only charge with a compatible charger from the manufacturer or reputable retailer.
  • Beware of substandard and counterfeit chargers.
  • Recycle properly, don’t dispose of them in the general waste or normal recycling.

Buying a mobile phone or tablet

  • Whichever you choose, buy your mobile phone or tablet from a reputable retailer rather than a third-party seller online, as it may not have passed all the necessary safety checks.  
  • Beware buying substandard or counterfeit chargers for your device as there are many dangerous chargers available.
  • Look for a manufacturer's name, a model number, and a UKCA or CE mark but don’t rely solely on these as they can be faked by unscrupulous sellers.
  • There should be at least 9.5 mm between the live and neutral pins and the edge of the plug.
  • Register your mobile phone or tablet so you can be contacted easily if there is a safety recall of your product. It’s also much easier to return a faulty item or order a repair if it’s registered.

Using and charging a phone or tablet safely

  • Keep mobile phones and tablets away from heat sources and liquids, especially direct sunlight, humidity, and water.
  • It is dangerous to use devices while bathing or showering unless suitably IP rated. You should never use a device in the bath or shower whilst it is charging and connected to a socket-outlet.
  • Exposing a phone or tablet to extreme temperatures can be dangerous. Don’t leave it in a parked car where it could get cold in winter or hot in summer.
  • Most phones and tablets use lithium-ion batteries that naturally get warm during charging. But if they are too hot to handle, stop using it, unplug from the charger (if it’s charging), and seek advice from the manufacturer.
  • Pack and handle your device carefully when on the move. Damaged batteries (dropped, crushed, or punctured) can become volatile and shouldn’t be used.
  • Regularly inspect cables for fraying, broken casing, or exposed wires, and check the charger plug for scorch marks or loose pins.
  • Most mobile phones and tablets are charged via a USB-type cable, and charger- a direct plug-in device with standard plug pins, that converts the UK mains voltage to a level suitable for your device. Only use a compatible USB charger from a reputable source as there are many substandard, dangerous chargers available.
  • Supervise children if they are charging their own devices
  • If you need additional or replacement chargers, go back to the original manufacturer or a reputable retailer as counterfeit and substandard chargers often fail to meet safety standards.
  • Don’t charge devices under pillows or on soft furnishings such as sofas and beds as this traps heat and can start a fire. Charging on a hard, stable, flat surface allows heat to dissipate.
  • Don’t cover the phone, tablet, or charger while it is plugged in. It’s recommended not to leave devices charging while sleeping or unattended to avoid the risk of overcharging and overheating.
  • Once the battery is full unplug the charger.
  • While charging, if you notice any odd smells or any sparking or smoke, or any swelling, cracks or damage, unplug immediately and contact the retailer and/or manufacturer.

ALWAYS

  • Do plenty of research first before buying.  
  • Buy a known and trusted brand from a reputable retailer.
  • Keep mobile phones and tablets away from heat sources and liquids.
  • Charge on a hard, stable, flat surface to allow heat to dissipate.
  • Supervise children if they are charging their own devices.

AVOID

  • Buying from third-party sellers online. 
  • Charging under pillows or on soft furnishings such as sofas and beds.
  • Using the phone or tablet if it is too hot to handle.
  • Using the phone or tablet if you notice any damage or sparks.
  • Buying substandard or counterfeit chargers as they often fail to meet safety standards. 

Stay safe with electrical products

Check plugs and sockets

Regularly check the charger and/or plug and your socket-outlet for burn marks, sounds of ‘arcing’ (buzzing or crackling) or if it feels too hot to touch. 

Protect with an RCD

An RCD (residual current device) in your consumer unit (fusebox) protects you from electric shocks should there be a fault with the charger. If you don’t have RCD protection, use an RCD plug on the socket where the charger is plugged in. 

Disposing of a mobile phone or tablet safely

Don’t throw these devices into the general waste or in the normal recycling. Because they contain lithium-ion batteries, if they get crushed or damaged, they can spark dangerous fires in recycling centres or bin lorries. 

They must be recycled properly. Check our guidance on recycling electricals or find out more on Recycle Your Electricals.

Additional info

Producers of counterfeit phone chargers are developing new and dangerous tactics to dupe consumers into thinking their product is genuine.

Our own testing of counterfeit and look-alike Apple chargers revealed metal weights had been inserted into several fakes to compensate for the missing weight that would usually indicate the use of genuine high-quality components.
