Is a new battery worth getting?

The typical Apple Battery lasts about two years with normal usage. All batteries deplete over time. Check your Battery Health level in Settings > Battery > Battery Health. If the figure is below 80%, you should get a new battery or risk the device going dead just when you most need it. Check this link...

Save a few, and troubleshoot the charge...

Troubleshooting iPad Charge:

A. Start Here: If your iPad won't Charge - Apple Support

B. Which Cables to Use: iPad Accessories - Power & Cables Power & Cables - Apple

C. Try what is on these Links:

• If your iPhone, iPad, or iPod touch won't Turn On or is Frozen - Apple Support
• If the Screen isn’t Working On your iPhone or iPad - Apple Support
• If your iPad won't Charge - Apple Support

D. Use an Apple Brand Cable:

Do not use a third party cable - cool though it may look, a fabric, third-part cable would likely tear - (Apple cable's are plastic and are intended for Apple).

E. About Battery Health:

Apple doesn't have Battery Health on an iPad. But, for note, Apple recommends that you get a new battery on an iPhone once its Battery Health reaches 80%.

F. A Faulty Device?:

So, is this covered under warranty? Note that this comes with a one-year, out-of-the-box, limited-warranty. So, set up a Genius Bar Appointment, asking them if this a faulty device.
