• Safety standards: The recall led to a significant increase in Samsung’s focus on safety standards. Samsung implemented stricter quality control procedures and established a new battery safety team to oversee the development and testing of all batteries used in its products.

Battery Health and Degradation

Like all rechargeable batteries, the Galaxy Note 7’s battery degrades over time. This means that it loses its ability to hold a charge as efficiently, leading to shorter battery life. While this process is inevitable, you can understand the factors that contribute to degradation and learn how to prolong your battery’s lifespan.

Factors Contributing to Battery Degradation

Battery degradation is influenced by a combination of factors, including:

• Charging Habits: Frequent full charging and discharging cycles can stress the battery, leading to faster degradation. Constantly keeping the battery at 100% or letting it drain to 0% can also have a negative impact.
• Temperature: Extreme temperatures, both hot and cold, can accelerate battery degradation. Storing your phone in a very hot or cold environment should be avoided.
• Number of Charge Cycles: Each time you fully charge and discharge your battery, it experiences a charge cycle. Over time, these cycles contribute to battery degradation. A typical lithium-ion battery can withstand around 500-1000 charge cycles before experiencing significant degradation.
• Time: Even if you don’t actively use your phone, the battery will degrade naturally over time. This is due to the internal chemical processes that occur within the battery.

Expected Battery Life Cycle

The expected battery life cycle for a typical smartphone battery is around 500-1000 charge cycles. This means that after 500-1000 full charges and discharges, you may start to notice a significant decrease in battery life. However, factors like charging habits and temperature can affect this cycle, potentially shortening or extending it.

Identifying Signs of Battery Degradation

Several signs can indicate battery degradation:

• Shorter Battery Life: You may notice that your phone’s battery drains faster than before, even with similar usage patterns.
• Increased Charging Time: It may take longer to fully charge your phone than it used to.
• Sudden Battery Drain: You may experience sudden and unexpected battery drops, even when the phone is idle.
• Swelling or Bulging: In rare cases, a severely degraded battery might swell or bulge, which can be a safety hazard. If you notice this, stop using your phone and contact a service center.

Maintaining Battery Health

Here are some tips to help maintain your battery’s health and prolong its lifespan:

• Avoid Full Charging and Discharging: Instead of charging your phone to 100% and letting it drain to 0%, try to keep the battery within the 20-80% range. This reduces stress on the battery and can extend its lifespan.
• Use Original Charger: Using a non-certified or low-quality charger can damage your battery. Always use the original charger provided with your phone.
• Minimize Heat Exposure: Avoid exposing your phone to extreme temperatures, such as direct sunlight or hot car interiors.
• Turn Off Unused Features: Features like Bluetooth, Wi-Fi, and GPS can drain your battery quickly. Turn them off when not in use.
• Update Software Regularly: Software updates often include battery optimization features that can improve battery performance.
