Last year marked the first time the number of units shipped didn't see any growth, according to venture capitalist Mary Meeker's annual Internet Trends report.
In fact, the number actually fell by 0.5 percent, after seeing a small growth of just two percent in 2016.
The report also addresses how people around the world are accessing the internet, with more people than ever browsing for an average of 5.9 hours day.
It's said they're browsing on mobile, which suggests users could be hanging onto their older models instead of upgrading and buying new phones.
According to Meeker's report, Apple is in first place in a ranking of the world's biggest 20 internet companies, with Amazon following in second place.
Meanwhile, Alibaba - China's biggest - finds itself at number six, and Tencent follows closely behind.
Also highlighted in the report is the current struggle tech companies are facing with regards to data privacy.
Firms usually find themselves relying on data to improve app experiences for users, but the increased scrutiny on how this data is handled has put them in something of "privacy paradox".
