Every customer checks the battery health before buying an iPhone whether it’s new or used. For those who don’t know, battery health is basically the charge holding capacity of a battery. 100% battery health means that the battery has 100% charge holding capacity. As the user starts using their phone, this percentage starts to decrease slowly.

According to the Apple’s official report, when an iPhone battery completes its 500 charge cycles means 500 times the user charge it between 0 to 100% and then drain it to almost full to charge again, the battery heath decrease by around 20%.

Speaking frankly, it’s not possible to maintain 100% battery health all the time. It is going to decrease for sure not matter what you do but there are some ways you can slow down the pace at which it is decreasing.

In this article, we will tell you some aspects that actually affect the battery health of your iPhone and by controlling them you will be able to stand at good percentage value.

Don’t over exposure your iPhone to heat

Let’s see how heat affects battery health and how to avoid that:

Overexposure to sunlight can actually damage the iPhone or any other smartphone battery because of excessive heat. Especially in countries like India where the average temperature is almost 35-40 degrees celsius. Try not to use your phone in excessive sunlight. Also do not put your phone directly under the sunlight like on car dashboard or any other places. Always try to place your phone in a cool moisture-free environment.

Adapt right charging habits

Charging habit is also a factor that affects battery health. Let’s discuss this aspect in detail:

  • Avoid using your iPhone while charging. Because charging increases the temperature of our phones and simultaneously using it can cause battery damage. Also avoid putting your phone on charging when your phone’s temperature is high, wait for it to cool down and then charge it.
  • Remove protective covers before putting your phone on charging. We know it is not always possible for you to do but if you do it, it is going reduce the heat while charging.
  • Do not charge overnight. Some people have misconceptions about overnight charging but it surely affects the battery health. Because when we charge our phone overnight so in this duration, when the phone fully chargers after some time, the battery drops 1% or 2% charge then the charging starts again and this process repeats overnight.  That’s why in the latest iPhones we have an option for optimize charging. Even optimize charging option is not that efficient so try to avoid overnight charging.
  • Do not put your phone on charge when the battery is almost 0%. Try to charge it when it’s around 20%. Because when the battery is below 20% it takes so much load in power supply. This is the very important point among these and if you follow this regularly, it will surely take care of your battery health.
  • Always use an original company charger, do not use any duplicate charger same with a lightning cable. Use the original charger adpater and lightning cable by Apple.
  • Do not always use a fast charger. If you are someone who always uses a fast charger then avoid using it all the time. When there is no need to charge your phone fast, especially when you are at your home, you can use the regular charger.
