Batteries are consumables, and their lifespans are affected by their usage patterns and environments.

If you find yourself charging your phone too often,
and your battery life has noticeably diminished, visit your nearest service centre.

Battery Deterioration

Normally, signs of battery deterioration include drastic decreases in battery life and unexpected shutdowns.

Learn about unexpected device shutdowns.
  • Electrochemical Deterioration of the Battery

    These events occur after repetitive battery use, resulting in electrochemical deterioration.

    High levels of deterioration could cause steep and instantaneous voltage drops,
    thereby resulting in the device shutting down in order to preserve the electrical components.
  • Shutdown Due to the Usage Environment

    An extremely cold environment may cause a greater drop in voltage.

    In this case, the device will shut down to protect its components.

Signs of Battery

As battery efficiency decreases, the battery may deplete drastically or shut down, even if the screen indicates that there is plenty of battery power left.

If you are having issues with a deteriorated battery, visit your local Samsung Support Centre for advice.

This can occur in cold winter temperatures,
and the frequency may increase depending
on the level of deterioration.

Certain demanding apps such as gaming and
camera apps, may cause a drop in performance
and decreased response times.

When to Replace
the Battery

If you are frequently experiencing unexpected shutdowns, drastic decreases in battery life
or any other battery-related issues, visit the nearest service centrer to have your device checked.

Depending on your device's warranty, you may qualify for a free replacement.

    Multi-level Safety Design

    In order to prioritise customer safety and convenience, Samsung has
    implemented a multi-level safety check during device production.

    Multiple tests are performed to accommodate not only the battery design
    but also impact mitigation for dropped devices.

    Both design safety and software protection algorithms are crucial
    factors in production.

    ※ Test type and scope may vary depending on the product.

Thorough Quality Assurance

Samsung Galaxy complies with international safety standards in order to provide safe and high-quality batteries.

We provide batteries that have gone through internal verifications and quality tests by trusted third-party CAs.

※ Additional certificate outside of the global requirements may vary by country/product.
