According to the Reviews.org Smartphone Lifespan Report, batteries are one of the top reasons why people upgrade phones, beaten only by performance issues.
That means phone upgrades are increasingly driven by day-to-day usability problems rather than a desire for the latest models and features: 18% of respondents cite battery issues as their main reason to upgrade, and 22% cite poor performance.
Smartphone battery problems can be frustrating, whether it's quick-draining batteries, slow or sporadic charging, or sudden drops in battery life.
