Do sealed new phones lose battery in storage
Yes, sealed new phones can still lose battery capacity over time, even when stored in a sealed condition. This phenomenon is known as "shelf life" or "storage capacity loss." Here's why:
- Chemical reactions: Lithium-ion batteries, like those used in most modern smartphones, are prone to chemical reactions that can cause capacity loss. These reactions occur even when the battery is not in use, as the chemicals inside the battery continue to degrade over time.
- Self-discharge: Lithium-ion batteries naturally self-discharge, meaning they lose capacity even when not connected to a charger or device. This self-discharge rate is typically around 2-3% per month, but it can vary depending on factors like temperature, storage conditions, and battery age.
- Aging: As batteries age, their internal components can degrade, leading to capacity loss. This is a natural process that occurs over time, even if the battery is not used.
- Storage conditions: The storage conditions of the phone, such as temperature, humidity, and exposure to light, can also impact battery capacity loss. For example, high temperatures can accelerate chemical reactions and self-discharge.
The rate of battery capacity loss in sealed new phones can vary depending on the manufacturer, model, and storage conditions. However, here are some general estimates:
- After 6 months of storage, a new phone's battery capacity might drop by around 10-20%.
- After 1 year of storage, the capacity loss could be around 20-30%.
- After 2 years of storage, the capacity loss could be around 30-40%.
It's essential to note that these estimates are approximate and can vary depending on the specific phone model and storage conditions.
To minimize battery capacity loss in sealed new phones:
- Store the phone in a cool, dry place (around 20°C/68°F and 40% humidity).
- Avoid exposing the phone to direct sunlight or high temperatures.
- Keep the phone away from moisture and humidity.
- Avoid storing the phone with a full or empty battery; instead, charge it to around 50% capacity.
Keep in mind that these measures can help slow down the capacity loss process, but they won't completely prevent it. If you plan to store a new phone for an extended period, it's a good idea to check the manufacturer's recommendations for storage and maintenance.
