Most and Least Reliable Phone Brands

That’s where the reliability and owner satisfaction information from CR’s annual smartphone survey can be a big help. Every year we ask our members about their experience with their phones—the problems they’ve encountered, how long the battery lasts on a single charge, and so on.

From 2022 to 2024, CR members shared insights on more than 128,000 smartphones purchased new since 2018 and owned for no more than five years. To determine the predicted brand reliability marks in our smartphone ratings, CR analyzed this data using a statistical model to estimate how likely products from a particular smartphone brand are to experience problems by the end of the second year of ownership.

Here’s a detailed breakdown of who makes the most and least reliable phones, as well as information on owner satisfaction, which is based on the proportion of members who are extremely likely to recommend their smartphones to friends and family.
