iPad mini 4
If you can help it, we recommend avoiding the fourth-generation iPad mini, also known as the iPad mini 4.
However, you must remember that the iPad mini 4 was released all the way back in the fall of 2015. It's nearly four years old now.
The iPad mini 5 is superior in every way. Not only will it get better software support, its hardware blows the iPad mini 4's out of the water.
Apple's iPad mini 4 uses a dual-core A8 processor paired with 2GB of RAM while the iPad mini 5 uses a much newer A12 Bionic chip with 3GB of RAM.
If you like to use your iPad for conference calls with co-workers, have chats with friends and family around the world, or shoot photos and videos, note that the iPad mini 5 has much better cameras.
The iPad mini 5 is more expensive, but it's worth the investment.
