If you are finding that your phone is getting slow at charging, here are some of the possible causes and solutions:
– Incompatible or faulty accessories, such as power brick, USB cable, or charging pad/mat (for wireless charging). Choosing a charger or brick with higher amperage e.g., a power brick with 2 to 3 amps could help speed up charging, as could making sure that you are using an authentic charging (USB) cable that is in good condition. Using a different USB cable and power adapter could be a good first try at solving the problem.
– Wireless charging slowing things down. Wireless charging tends to be slower than cable charging, so consider switching back to traditional adapter & USB cable charging (bearing in mind the point made above).
– Damage to or dirt in the charger port on the phone (where the cable plugs in). If there’s dirt, use a wooden toothpick or a soft brush to clean it out. If it is broken, a technician, perhaps recommended by your local phone shop can fix it for you.
– Background apps using power. To stop this happening (Android), use Settings > Battery> Battery Usage to find the apps and disable their background battery usage. Select the app and tap Background restriction. For iPhones or iPads, go to Settings > Battery and tap Show Activity.
– An old or defective battery. To check an iPhone or iPad’s battery capacity, use Settings > Battery > Battery Health and if the Maximum Capacity is 80 per cent or lower, this may be a sign that the battery needs replacing.
– Using the phone while charging. This should be avoided because it causes the phone to charge more slowly, raises battery temperature, and increases the chances of fraying the charging cable.
