The battery is one of the most important components of every iPhone. Over time, its capacity decreases, which can cause shorter operating times, unexpected phone shutdowns, or a drop in performance. Fortunately, Apple makes it possible to quickly check the battery health without installing additional apps.<\/p>\n\n\n\n

Where to check battery health?<\/h2>\n\n\n\n

To check the battery status:<\/p>\n\n\n\n

    \n
  1. Open Settings<\/strong>.<\/li>\n\n\n\n
  2. Go to Battery<\/strong>.<\/li>\n\n\n\n
  3. Choose Battery health<\/strong> or Battery health and charging<\/strong> (depending on the iOS version).<\/li>\n<\/ol>\n\n\n\n

    You will find there the two most important pieces of information:<\/p>\n\n\n\n

      \n
    • Maximum capacity (%)<\/strong> \u2013 shows how much capacity is left compared to a new battery.<\/li>\n\n\n\n
    • Peak performance<\/strong> \u2013 indicates whether the battery is able to supply sufficient power for the proper operation of the device.<\/li>\n<\/ul>\n\n\n\n

      What does maximum capacity mean?<\/h2>\n\n\n\n

      Apple acknowledges that the battery retains good health up to approximately 80% capacity<\/strong>.<\/p>\n\n\n\n

      Roughly:<\/p>\n\n\n\n

        \n
      • 100\u201390%<\/strong> - battery in very good condition.<\/li>\n\n\n\n
      • 89\u201385%<\/strong> \u2013 natural wear and tear, usually does not require replacement.<\/li>\n\n\n\n
      • 84\u201380%<\/strong> \u2013 the battery is noticeably worn out, operating time may be shorter.<\/li>\n\n\n\n
      • Below 80%<\/strong> \u2013 it is worth considering replacing the battery.<\/li>\n<\/ul>\n\n\n\n

        Messages worth paying attention to<\/h2>\n\n\n\n

        If the iPhone displays messages such as:<\/p>\n\n\n\n

          \n
        • \u201eService in battery health,<\/li>\n\n\n\n
        • \u201eService recommended,<\/li>\n<\/ul>\n\n\n\n

          this means that the device requires diagnostics.<\/p>\n\n\n\n

          Why does battery health decline?<\/h2>\n\n\n\n

          Battery consumption is primarily affected by:<\/p>\n\n\n\n

            \n
          • number of charge cycles,<\/li>\n\n\n\n
          • frequent discharging to 0%,<\/li>\n\n\n\n
          • using non-original or damaged chargers,<\/li>\n\n\n\n
          • intensive device usage.<\/li>\n<\/ul>\n\n\n\n

            This is a completely natural process \u2013 every lithium-ion battery loses its capacity over time.<\/p>\n\n\n\n

            Is it worth replacing the battery?<\/h2>\n\n\n\n

            If your iPhone drains quickly, shuts down when the battery level is still relatively high, or its battery health has dropped below 80%, replacing the battery usually significantly improves the user experience.<\/p>\n\n\n\n

            It is worth choosing a service center that uses high-quality parts and performs a full device diagnostics after the repair.<\/p>\n\n\n\n

            Summary<\/h2>\n\n\n\n

            Checking iPhone battery health takes less than a minute and allows you to assess whether the battery is still working properly. Regular monitoring of its condition will help you avoid sudden phone issues and plan a replacement well in advance.<\/p>\n\n\n\n
