Whether you're in the market for a new laptop or simply want to make your current one last longer, this guide can help you keep your laptop battery running efficiently. Learn some easy tips for everyday maintenance and ways to optimize your software and existing tools.

Mastering Laptop Battery Care

To maximize the lifespan of your laptop battery, it's crucial to practice proper care and management techniques. Consider the following factors:

  • Optimal Charging Cycles: While your laptop will still function if the battery runs down to 0%, try to avoid letting it drain completely. Instead, maintain the battery level between 20% and 80% to maximize battery life.

  • Power Settings Adjustment Adjusting power settings, such as screen brightness and sleep mode, can significantly extend battery life.

  • Storage Maintenance: If you won't be using your laptop for an extended period, store it with around a 50% charge.

  • Regular Health Check: Periodically monitor your battery's health and capacity to assess its condition and determine if a replacement is needed.

  • Choosing the Right Laptop: Opt for a laptop known for its reliable battery life, such as those equipped with lithium-ion batteries, to enhance overall performance and longevity.

By following these guidelines, you can achieve a longer battery lifespan and improved performance from your laptop.

The Power Within: Understanding Lithium-Ion Batteries

  • Lithium-ion batteries are a type of rechargeable battery. They work by moving lithium ions back and forth between positive and negative electrodes, powering our devices during countless charge and discharge cycles. When a lithium-ion battery is charging, the positive electrodes move lithium ions through the battery and store them with the negative electrodes. When the battery is removed from the charger, the lithium ions pass back through the battery from the negative to the positive electrodes, releasing energy to power up your device!

  • Unfortunately, over time, the battery capacity naturally diminishes due to internal chemical reactions. To keep your battery performing at its best, it's vital to shield it from extreme temperatures that could harm its performance.

  • Every time you fire up your laptop, your battery embarks on another charge cycle, gradually ticking away at its finite lifespan, which typically ranges from 3 to 5 years. 

  • A charge cycle is when you use all your laptop’s battery capacity, and it's crucial to understand that one charge cycle doesn't necessarily mean a full 0% to 100% charge. For example, if one day you use only half of your battery's capacity and recharge it to 100%, and then use half again the next day and fully recharge it, this only equates to one cycle.

  • Lithium-ion batteries have truly revolutionized the world of portable electronics, offering unmatched energy density and rechargeability in a compact, lightweight package. Their versatility makes them perfect for laptops where space and weight are at a premium. Unlike their predecessors, these batteries are immune to the memory effect, eliminating the need for tedious full discharges before recharging. Whether you’re working on an important document or streaming your favorite shows on the go, you won’t be caught short without charge thanks to the long-lasting and rechargeable power of lithium-ion batteries.

Checking Up: Regular Battery Health Check for Your LG Laptop

To ensure your LG laptop battery performs optimally and lasts long, consider the following:

  • Regular Battery Health Checks: Consistently examine the battery for signs of wear, like bulges or leaks, to maintain its wellbeing. For any internal issues, contact authorized LG service centers rather than attempting to open the laptop yourself, as unauthorized disassembly may void the warranty.

  • Clean the Bottom of your Laptop: Keep the underside of your laptop clean and free from debris.

  • Use Diagnostic Tools: Monitor the battery's health using diagnostic tools to gain insights into capacity, charge cycles, and performance.

How to generate a laptop battery report

To generate a battery report on your LG laptop, follow these steps:

  • Open Command Prompt: Search for "CMD" or "Command Prompt" in the Windows Start menu.

  • Generate the Report: Once Command Prompt is open, type powercfg /batteryreport and press Enter.

  • Locate the Report: If successful, Command Prompt will indicate that a battery life report has been saved to your user folder. Navigate to your user folder, typically located at C:\Users\<yourusername>, to access the generated report.

When examining the Battery Report, focus on key sections such as:

  • Installed battery: This section provides information about your battery, including its manufacturer, serial number, and design capacity.

  • Recent usage: Here, you'll find details on recent battery usage, such as the time the report was generated, the time the system was on battery power, and any unexpected shutdowns.

  • Battery usage: This section offers insights into battery consumption, including usage over the last three days, average battery life, and historical usage patterns.

By reviewing these sections, you can gain valuable insights into your battery's performance, usage patterns, and overall health.

Optimal Battery Settings: Power Settings and Hibernation Modes

To get the best performance and longest lifespan out of your LG laptop battery, it's important to make a few adjustments:

  • For laptop models released before 2022: Access battery settings through the LG Control Center. Simply open the control center and select 'Power Management Settings'.
  • For laptop models released after 2022: Use the LG Smart Assistant and navigate to ‘Power Setting’.

Additionally, minor adjustments can make a significant difference in conserving battery life:

  • Dimming the screen brightness.
  • Setting the screen to turn off after shorter periods of inactivity.

If you're not going to be using your LG Laptop for a while, consider using hibernation mode instead of sleep mode. Hibernation mode saves your work and shuts down the laptop while using very little power. It's a great option for when you need to take a break and come back to your work without draining the battery unnecessarily.
