There are several reasons why the battery of a new iPad may drain quickly. One common reason is that the device is running multiple apps or processes in the background, which can consume a lot of power. Another reason could be that the screen brightness is set too high, or that certain settings such as push notifications or location services are draining the battery faster. It's also possible that the battery itself is defective and may need to be replaced. **

For studying architecture, the iPad Pro would be the most suitable option due to its powerful performance and larger screen size. The iPad Pro offers advanced features such as the Apple Pencil compatibility, which is essential for sketching and designing architectural drawings. Additionally, the iPad Pro's multitasking capabilities and high-resolution display make it ideal for running architecture software and viewing detailed designs. Overall, the iPad Pro provides the necessary tools and performance for architecture students to effectively study and work on their projects. **

An iPad is not necessarily required for architecture studies, but it can be a useful tool for students in this field. With its portability and ability to run design and drafting software, an iPad can be a convenient device for sketching, note-taking, and presenting architectural ideas. However, traditional methods such as hand-drawing and physical model-making are also important skills for architecture students to develop. Ultimately, the use of an iPad in architecture studies depends on the specific program and the preferences of the individual student. **

If your iPad's battery is defective, you can contact Apple Support or visit an Apple Store to inquire about getting a replacement. If your iPad is still under warranty, Apple may provide a replacement device at no cost. If the warranty has expired, you may have the option to purchase a replacement battery or pay for a repair service. It's important to reach out to Apple directly to discuss your options and determine the best course of action for getting a new iPad with a defective battery. **

To save battery on the iPad, you can adjust the screen brightness to a lower level, turn off background app refresh, disable push notifications for apps that are not essential, and enable Low Power Mode when the battery is running low. Additionally, you can limit the use of location services and disable unnecessary features like AirDrop and Bluetooth when not in use. Finally, closing out of apps running in the background can also help conserve battery life. **

There could be several reasons why an iPad battery is not fully charging. It could be due to a faulty charging cable or adapter, a problem with the power source, or a software issue. Additionally, the battery itself may be worn out and in need of replacement. It's also possible that there is a problem with the charging port on the iPad. Troubleshooting these potential issues and trying different charging methods can help determine the cause of the problem. **

I'm sorry, but I am unable to check the battery status of your iPad as I do not have access to that information. You can check the battery status of your iPad by looking at the battery icon in the top right corner of the screen or by going to the Settings app and selecting "Battery." **
