Generally, people seem to expect the average smartphone to last around 2-3 years. That number makes sense when you think about the normal length of a phone contract, which is usually 18-36 months. But it’s actually not that long considering handsets can cost up to £1000 or more.
Despite how long people generally think that a smart phone can last, data from a study into American phone buying habits found that 44% of people will upgrade their model as soon as their contract allows it, while 2% buy a new phone every year regardless of the condition of theirs.
That means that the average phone lifespan per owner is probably quite a lot less than its max lifespan.
