1 year old iPad 9th gen. not charging after updating to ipados 18.2

Anyone knows a solution for this? My iPad is been charging at a very slow speed or it wont charge at all always showing “not charging” since the iOS 18 update, I’m on the latest iOS 18.2 and no fix for this yet. Im using both original apple cable and connector.

As a diagnostic exercise, have you tried charging your iPad using a USB Type-A Power Adapter rated at 12W (i.e. 2.4A @5V) or greater? This completely removes USB PD (Power Delivery) and the associated charge controller from the equation.

Your USB-C Power Adapter will need to support USB PD to be able to successfully charge your iPad. Many third-party Power Adapters use proprietary charging standards (e.g. QuickCharge - QC) that are not supported by Apple devices.

Troubleshooting generally requires substitution of the Power Adapter and cable for another known-good item. Most models of iPad require a Power Adapter rated at 12W (i.e., 2.4A @5V) or greater to reliably charge. 5W Power Adapters (1.0A @5V) intended for older models of iPhone are inadequate to charge an iPad; if the iPad charges at all, charging will be very slow. Recent models of iPad are supplied with a 20W USB-C Power Adapter.

Some third-party USB-C power adapters (and portable PowerBanks) may not support USB PD (Power Delivery). Power Delivery mutually negotiates the charging voltage; the source, load and cable are all elements involved in the negotiation protocol. Unless the Power Adapter explicitly supports USB PD, it will almost certainly fail to charge the iPad; proprietary charging standards, such as QC (Quick Charge), are not supported.

Many computer USB ports also cannot source sufficient power to charge an iPad. Unless explicitly designed for charging connected devices, computer USB ports are typically limited to 0.5-1A @5V (i.e., 2.5-5.0W).

If you continue to experience difficulties when using an appropriate Power Adapter of 12W or greater, you might be best advised to seek assistance directly from from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page. Alternatively, you can initiate and manage your support cases from Apple devices using the excellent Apple Support App. If not already installed, the App can be downloaded from the App Store:

You might also visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to test and assess your iPad, Power Adapter and cable(s):

The objective of the test was to demonstrate that the iPad was still able to charge using a basic Power Adapter, this bypassing USB Power Delivery protocol that actively negotiates the charging voltage between the Power Adapter and iPad.

As described, the basic Power Adapter that you were using with your iPad3 is perhaps only able to supply 5-10W (i.e. 1-2A @5V), this being only just sufficient to charge your iPad at all.

Having demonstrated that the iPad will still accept power, try to charge with your USB-C Power Adapter. In some situations, charging from a basic 5V Power Adapter can "reset" the charge controller.
