Secondly, avoid full 0–100% charge cycles daily. Modern batteries prefer partial charges. Try to keep your battery between 20% and 80% charge for optimal health.
Always use the original charger or a high-quality, compatible charger. Generic or low-quality chargers can damage your battery. Lastly, if you plan to store battery at 50% if unused for long periods, charge it to 50-60% before storing. Storing a battery completely empty or full can harm its capacity.
5. Tools & Software to Monitor Battery Usage
Knowing how your laptop uses its battery is key to making it last longer. There are many tools, both built-in and third-party, that offer insights into your battery’s health and usage.
Windows users can check the Battery Usage feature in Settings (System > Battery) to see which apps use the most power. The powercfg /batteryreport command in Command Prompt creates a detailed HTML report. This report shows your battery’s capacity, charge cycles, and usage history. For more detailed info, tools like BatteryInfoView and HWMonitor are great. They show battery information, charge/discharge rates, and health, and also monitor temperatures and fan speeds.
macOS users have great built-in tools. Go to System Settings > Battery to see detailed usage statistics. You’ll get a graph of your battery level over the last 24 hours and a list of apps using the most energy. The “Health Information” section shows your battery’s maximum capacity and cycle count. These built-in tools in Windows/macOS are usually enough for most users to track battery consumption and find problem apps or settings. Checking these tools regularly can help you fix issues before they get worse.
