Something I want to replace is iphone6, which looks like a small box. When I come to university, my parents brought me this Iphone. It had many functions. I can use it to download applications by Appstore, some of which are helpful for my study. For instance, I could use it to connect the internet and find information. And of cause, by installing e-dictionary, I could easily look at the means of new vocabularies. Due to it has too much functions, I always take it with me. My life became more convenient than before with the help from my cellphone. However, after used for several years, it can not calculate quickly, which promoted me to buy a new one. I think the newest Iphone can provide me higher speed, which can save me a lot of time used to wait for opening applications. The new phone also has a better camera, which is good for taking better photos. However, as the old one is still working rightly, it is hard for me to persuade my parents to buy me a new one.
