The mobile phone<\/a> is the most frequently used tech device in everyday life. The good news for the user is that looking after it is far less demanding in terms of time and effort than caring for a pet. Here are the tips to follow to ensure a long life for your device.<\/span><\/p>\n

How to assess the health of the battery<\/span><\/h2>\n

The <\/span>battery<\/b> is one of the most essential components of the device. For this reason, the user has tools to monitor its condition and optimise its performance. There is no need to download third\u2011party apps. The built\u2011in operating system does an excellent job of allowing you to tailor power use to your real needs.<\/span><\/p>\n

For example, if you mainly use your phone for calls, you can enable the <\/span>most effective power\u2011saving mode<\/b>, which significantly increases the time between charges. In the long run, this practice helps preserve the battery by reducing the number of full charge and discharge cycles.<\/span><\/p>\n

Before using the various power\u2011saving modes, it is <\/span>wise to read the documentation<\/b> to understand their effects on your specific phone. In some cases, these modes disable app notifications, which could mean missing important information. A careful review of the options is therefore recommended.<\/span><\/p>\n

Precautions to take for the battery<\/span><\/h2>\n

By adopting good habits, you may not need to replace the <\/span>battery<\/b> before you change your phone.<\/span><\/p>\n

To increase this likelihood, it is recommended to:<\/span><\/p>\n

    \n
  • Never leave the battery <\/span>completely flat for a long period<\/b>. How quickly you recharge it is a key factor.<\/span><\/li>\n
  • Try not to charge beyond 85%<\/b> (some phones have a function to stop automatically at 80%).<\/span><\/li>\n
  • Avoid leaving the mains adaptor plugged into the wall indefinitely. This increases the risk of the adaptor failing, which can affect the <\/span>battery<\/b> during charging.<\/span><\/li>\n
  • Protect the phone from extreme temperature changes<\/b>.<\/span><\/li>\n<\/ul>\n

    Replacing the battery at home: the steps<\/span><\/h2>\n

    The question of whether you can change your smartphone <\/span>battery<\/b> yourself can, in most cases, be answered with yes.<\/span><\/p>\n

      \n
    • Entry\u2011level devices are often the easiest to repair, as the back cover comes off with little effort.<\/span><\/li>\n
    • Some mid\u2011range or high\u2011end models are also simple to take apart, as long as the back cover is easy to access.<\/span><\/li>\n<\/ul>\n

      For smartphones designed not to be opened, the success of the operation depends on <\/span>having the right tools<\/b> and on the <\/span>user\u2019s skills<\/b>.<\/span><\/p>\n

      If you decide to replace a <\/span>battery<\/b> in a phone that requires tools, the first thing to do is to <\/span>look up a video tutorial<\/b> that shows the process step by step. This will allow you to assess whether you have the tools and the know\u2011how.<\/span><\/p>\n

      Some models make the job harder by using glue to hold components in place. In these situations, it is more sensible to leave the task to <\/span>professional repairers<\/b>.<\/span><\/p>\n

      The procedure for replacing a <\/span>battery<\/b> follows a logical sequence, adapted to each brand:<\/span><\/p>\n

      Preparation and tools<\/span><\/h3>\n

      To carry out the replacement, you will need:<\/span><\/p>\n

        \n
      • Precision screwdrivers.<\/span><\/li>\n
      • A heat source (hot\u2011air gun, hairdryer, iOpener tool).<\/span><\/li>\n
      • Suction cup.<\/span><\/li>\n
      • Thin opening tool (plastic card, guitar pick).<\/span><\/li>\n
      • Tweezers.<\/span><\/li>\n
      • Adhesive remover.<\/span><\/li>\n
      • Replacement adhesive strips.<\/span><\/li>\n
      • The <\/span>new battery<\/b>.<\/span><\/li>\n<\/ul>\n

        Before you start, switch the phone off completely and remove the SIM tray. It is recommended to begin when the <\/span>battery<\/b> is charged to around <\/span>25%<\/b>.<\/span><\/p>\n

        Removing the back<\/span><\/h3>\n

        For most devices (except iPhones):<\/span><\/p>\n

          \n
        • Heat the back of the device to soften the adhesive.<\/span><\/li>\n
        • Use the suction cup to start lifting the back cover.<\/span><\/li>\n
        • Use the thin tool to work your way around and release the clips.<\/span><\/li>\n
        • Once the back is removed, disconnect the black clip (NFC port, if present) with the screwdriver.<\/span><\/li>\n<\/ul>\n

          Warning: A video for your exact model is essential.<\/b> Risk: The screen may crack while removing the back cover.<\/b><\/p>\n

          For iPhones:<\/span><\/p>\n

            \n
          • Remove the screws near the charging port and warm up the screen.<\/span><\/li>\n
          • Use the suction cup to gently lift the screen.<\/span><\/li>\n
          • Slide the tool around to unclip the screen.<\/span><\/li>\n
          • Remove the screen cable bracket and carefully disconnect it.<\/span><\/li>\n
          • Remove the other fixings to reach the <\/span>battery<\/b>.<\/span><\/li>\n<\/ul>\n

            Warning: A video for your exact model is essential.<\/b> Risk: The screen may be damaged when being prised off.<\/b><\/p>\n
