Galaxy’s High-quality, High-performance Battery

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 center.

Battery Decline

Normally, signs of battery decline include drastic decreases in battery life and unexpected shutdowns.
Learn about unexpected device shutdowns.

• Electrochemical Decline of the BatteryThese events occur after repetitive battery use, resulting in electrochemical efficiency.
  High levels of decline could cause voltage drops,
  resulting in device shutdown to preserve the device’s electrical components.
• Temporal Shutdown due to Usage EnvironmentAn extremely cold environment may cause a greater drop in voltage.
  In this case, the device might shut down temporarily to preserve its components.

Signs of Battery Decline

As battery efficiency decreases, the battery may noticeably deplete or shut down,
even if the screen displays plenty of battery power remaining.
If you are having issues with a declining or inefficient battery, visit your nearest service center.

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

With high-performance apps like gaming and
camera apps, you may experience a drop in
performance and slow response time.

When to Seek a Battery Check-up

If you are frequently experiencing unexpected shutdowns, noticeable decreases in battery life,
or any other battery-related issues, visit the nearest service center to have your device checked.
We may notify you through a device pop-up message, that your battery requires a check-up.

* A progressive battery notification will be provided.

1. Click on the notification in your ‘Status bar’.

2. Check the information on your battery’s status.

Safer and More Convenient

• Multi-level Safety DesignIn order to prioritize customer safety and convenience, Samsung has
  implemented a multi-level safety check during device production.
  Multiple tests are performed to accommodate not only 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 global requirements may vary by country/product.
