Battery Health and Performance in Refurbished iPhones: A Comprehensive Guide

When considering a refurbished iPhone, one of the primary concerns for potential buyers is battery health and performance. After all, a healthy battery is crucial for a seamless user experience. This blog post aims to address these concerns by providing a detailed and informative guide on battery health in refurbished iPhones.

Understanding Battery Degradation:

Like all rechargeable batteries, iPhone batteries naturally degrade over time, resulting in a decrease in their capacity to hold a charge. This degradation is mainly caused by charge cycles (a complete charge and discharge cycle) and environmental factors like extreme temperatures.

Refurbished iPhones and Battery Health:

Refurbished iPhones from WeSellTek undergo a rigorous inspection and restoration process, which if required includes replacing the battery if it falls below a certain health threshold (80%). This ensures that most refurbished iPhones come with healthy batteries capable of delivering similar performance to new devices.

Factors Affecting Battery Health in Refurbished iPhones:

    • Original Battery Age: If the refurbished iPhone was originally used for an extended period before refurbishment, the battery might have undergone some degradation even if replaced.
    • Refurbishment Process: Reputable refurbishers typically use high-quality replacement batteries. However, the quality of the battery can vary depending on the source. WeSellTek only use OEM quality battery's or manufacturer original batteries where possible ensuring performance is exactly as the device was new.
    • Usage Patterns: The way you use your iPhone, such as frequent gaming or high brightness settings, can also impact battery life.

Checking Battery Health in Refurbished iPhones:

All iPhones, including refurbished models, allow you to check the battery health directly from the settings. Navigate to Settings > Battery > Battery Health. Here, you'll see the maximum capacity of your battery, which indicates its ability to hold a charge compared to when it was new.

Maximizing Battery Life in Refurbished iPhones:

Regardless of whether you have a new or refurbished iPhone, following these tips can help you optimize battery life:

    • Enable Low Power Mode: This reduces background activity and conserves battery life.
    • Adjust screen brightness: Lowering the brightness can significantly improve battery life.
    • Close unused apps: Regularly closing background apps can help prevent unnecessary battery drain.
    • Disable location services for unnecessary apps: Location services can be a battery drain, so enable them only for apps that require them.
    • Update to the latest iOS version: Updates often include battery performance improvements.


While battery health is a valid concern when considering a refurbished iPhone, reputable refurbishers typically replace batteries with healthy alternatives. By understanding the factors affecting battery health and following best practices, you can ensure optimal battery performance in your refurbished iPhone. Remember, battery health naturally degrades over time, and eventually, replacement might be necessary regardless of whether the phone is new or refurbished.
