1. Clean the cache regularly. Every application of ipad will have its own cache cleaning function if it will generate cache.

2. Shut down and restart regularly. In fact, the ipad has the function of removing garbage, which can be seen from the long-term fluency of the ipad, but there is no way to achieve this function by keeping the machine on. So it's not bad to restart the machine and turn it on and off regularly, but it's good.

3. Delete it manually. This method is also carried out on a PC.

4. cherish the use. After all, a tablet is also a computer, so you should take good care of it when using it. You can download some auxiliary software, which may have the function of cclean. Or some battery housekeeper or something.

IPad is a series of flat-panel products launched by Apple, designed by a team led by design director Jonathan Ive. The first generation iPad went on sale on April 3rd, 20 10. The positioning of iPad is between Apple's smartphone iPhone and laptop products, and it provides functions such as browsing websites, sending and receiving emails, reading e-books, playing audio or video, playing games and so on. It is divided into four series: iPad, iPad mini, iPad Air and iPad Pro. In 2000, "iPad" was already an extremely important project within Apple. At first, it was a secret project based on multi-touch research and development, which was carefully protected by Jobs. After mastering the multi-touch technology, in 2002, Apple's hardware development department had the first iPad prototype, but the machine was bulky and the battery performance was too weak. So Apple continues to improve touch technology, and the tablet plan is postponed indefinitely.
