One of the key components of any laptop is without doubt its <\/span>battery<\/b><\/a>. Keeping it healthy is essential if you want to make the most of the device\u2019s main feature: <\/span>its portability<\/b>.<\/span><\/p>\n

Why do you need to keep a close eye on your battery?<\/span><\/h2>\n

Over time, every <\/span>battery<\/b> ages, which shows up as reduced runtime or longer charging times. Although these are the most common warning signs, they can sometimes be confused with issues related to the power supply or damage to the charging connector. <\/span><\/p>\n

Using diagnostic apps is the best way to monitor the health of your <\/span>battery<\/b>. <\/span>These tools help you anticipate how long your battery will remain usable, based on how you use your laptop.<\/b><\/p>\n

With these utilities, you can get precise information on:<\/span><\/p>\n

    \n
  • The rated (design) and actual capacity of the battery pack<\/span><\/li>\n
  • The current wear level<\/span><\/li>\n
  • Power consumption at a given moment<\/span><\/li>\n
  • The total number of cycles completed<\/span><\/li>\n
  • Estimated remaining runtime<\/span><\/li>\n
  • Internal temperature, and other data.<\/span><\/li>\n<\/ul>\n

    How can you check your battery health for free?<\/span><\/h2>\n

    There are different ways to get accurate data on the condition of your <\/span>battery<\/b>.<\/span><\/p>\n

    Using dedicated software<\/span><\/h3>\n

    Specialist programs provide far more detailed data on the state of the battery pack. They allow you to track how the <\/span>battery<\/b> changes over time and compare past statistics. <\/span><\/p>\n

    These applications are available as paid or free versions. <\/span>The free version is usually enough to access the essential information.<\/b><\/p>\n

    Here are a few examples of these monitoring tools:<\/span><\/p>\n

    Batteryinfo<\/span><\/h4>\n

    This app shows detailed information on the condition of the <\/span>battery<\/b>, split into two sections. The first lists the key characteristics: theoretical (rated) capacity, actual full-charge capacity, wear level, overall <\/span>battery<\/b> health and cycle count. The second section, the \u201clog\u201d, records the usage history: power source (mains or <\/span>battery<\/b>), charge percentage and live voltage. Every new usage session is logged.<\/span><\/p>\n

    Batterymon<\/span><\/h4>\n

    BatteryMon is a real-time monitoring tool that displays <\/span>battery<\/b> status as a graph. This visual view lets you check how evenly the cells are charging and discharging, and how fast they do so. <\/span>An irregular graph makes it easy to spot potential issues<\/b> so you can react straight away.<\/span><\/p>\n

    Batterybar<\/span><\/h4>\n

    Similar to BatteryInfo, BatteryBar provides data on charge level, capacities, cycles and voltage. Its interface appears as a status bar on screen, giving <\/span>quick access to critical <\/b>battery<\/b> information<\/span>. It also offers advanced options for configuring charging modes.<\/span><\/p>\n

    Battery care<\/span><\/h4>\n

    This software is designed to optimise battery performance. It tracks charge and discharge cycles to help you <\/span>extend your battery\u2019s lifespan as much as possible<\/b>. <\/span><\/p>\n

    It provides information on the remaining effective capacity, wear level and power consumption. A major bonus: the program also monitors the processor and hard drive temperature. <\/span>This is crucial, because excessive heat damages batteries.<\/b><\/p>\n

    Using built-in operating system tools<\/span><\/h3>\n

    You don\u2019t necessarily need to install extra software to get a report on your <\/span>battery<\/b> health.<\/span><\/p>\n

    Windows<\/span><\/h4>\n

    The method is a bit less intuitive than on macOS, but it\u2019s very effective.<\/span><\/p>\n

      \n
    • For Windows 8 and later<\/b>: Use the PowerShell tool.<\/span>\n
        \n
      1. Open the Start menu.<\/span><\/li>\n
      2. Type \u201cPowerShell\u201d into the search box.<\/span><\/li>\n
      3. Open the program.<\/span><\/li>\n
      4. Type the command <\/span>powercfg \/batteryreport<\/span> and press Enter.<\/span><\/li>\n
      5. You\u2019ll see the path where the report has been saved (usually in C:\\Users[Username]).<\/span><\/li>\n<\/ol>\n<\/li>\n
      6. For earlier versions of Windows<\/b>: Use the Command Prompt (cmd).<\/span>\n
          \n
        1. Open the Start menu.<\/span><\/li>\n
        2. Type \u201ccmd\u201d into the search field.<\/span><\/li>\n
        3. Launch the application.<\/span><\/li>\n
        4. Type the command <\/span>powercfg \/batteryreport<\/span> and press Enter.<\/span><\/li>\n
        5. The file <\/span>battery-report.html<\/span> will be created in the Users\/[Username] folder.<\/span><\/li>\n<\/ol>\n<\/li>\n<\/ul>\n
