If your iPad is charging but the percentage barely seems to move, the charger is often the reason rather than the battery.
iPad models can draw more power than an iPhone, particularly while the screen is on, apps are running or the device is being used for video, gaming or multitasking. A low-wattage charger may keep the battery from falling, but still charge it very slowly.
The cable matters too. Damaged or poor-quality USB-C cables can limit charging performance, and some older power adapters simply cannot deliver enough power for a larger iPad battery.
Heat can also slow things down. If the iPad becomes warm, charging may be reduced temporarily to protect the battery. Heavy use while plugged in can make this more noticeable.
For the quickest results, use a suitable USB-C power adapter, connect the iPad directly rather than through a low-powered hub, and leave the screen off for a while.
If charging remains unusually slow with a known-good charger and cable, check the USB-C or Lightning port for debris and restart the iPad before assuming the battery needs attention.
A slowly climbing percentage is frustrating, but in many cases the iPad is simply receiving less power than it can use.
