Some indications that you need to change your iPhone 4S battery:

  • Random reduction in battery percentage even when you are not using your iPhone.
  • Battery percentage dropping suddenly to 1% before switching off.
  • High battery drainage even on Airplane mode.
  • A swollen battery, which is generally caused by charging your phone at high temperature.
  • Sometimes a bulged battery lifts the display from the surface and can cause other problems.

How to maintain in future:

  • The first and most simple step for extending your battery life is to turn down brightness settings to the lowest level that is comfortable for you.
  • Always make sure that your Apple device is using the latest version of iOS available for that particular model.
  • Heat is bad for any kind of battery, and so are cold temperatures, so it’s best to keep your iPhone at room temperature as much as you can.
  • It is recommended that you do a full zero to 100% battery recharge (a “charge cycle”) maybe once a month only. This re-calibrates the battery, a bit like restarting your computer.
  • Charging your device when it’s inside certain styles of cases may generate excess heat, which can affect battery capacity. If you notice that your device gets hot when you charge it, take it out of its case first.
  • For optimal performance, calibrate your newly installed battery: Drain battery below 10%, then charge uninterrupted to 100%.
