Battery Health iPhone

The battery is one of the most important parts of an iPhone, but it's also something of a mystery. Since it's not as easy to replace as it is on some other phones, it's a good idea to keep an eye on how your battery is doing. Here's everything you need to know about iPhone battery health—from what counts as good capacity to how the battery performs across different models.

Check battery health on iPhone

Battery health is about how much of the original battery capacity is left. It's easy to check your own iPhone's battery health. You can do this directly on your phone:

  1) Open the app Settings and choose Battery
  2) Click on Battery health and charging

Now you can see your iPhone's battery capacity, its peak capacity, and get an indication of whether the battery needs service.
If you have English set as the language on your iPhone, check the battery health by opening the app Settings, choose Battery and then click Battery Health & Charging.

The capacity

A new iPhone has 100% battery capacity. Capacity decreases over time, and the worse the battery health becomes, the shorter the time it lasts between charges. As capacity decreases, the phone may have to throttle performance to avoid suddenly shutting down.

What is good battery health?

All lithium-ion batteries gradually deteriorate over time, no matter how carefully you use your phone. This is most noticeable when the battery doesn't last as long as it used to. When you buy a iPhone used via reNewed you always get a mobile phone that is tested and has a battery that still meets good standards. To ensure the user experience, we do not sell iPhones whose battery health is below 80%, which is the level at which it still works according to Apple's guidelines. Many iPhones maintain over 90% capacity after a year, thanks to the battery having a built-in reserve margin. As long as it stays above 80%, it works as it should.

Make your battery last longer

Want to make your iPhone's battery last longer? Here are some simple things you can do:

• ·         Keep the software up to date
  iOS updates often include improvements that extend battery life.

  ·         Use power saving mode when necessary
  It slows down performance and limits background activities to provide extra battery life when you need it.

  ·         Avoid extreme temperatures
  The iPhone's battery thrives best between 17–22 degrees Celsius. Cold and heat wear it down.

  ·         Be careful when charging
  If your phone gets hot while charging, you can remove the case or move it to a cooler location. NOTE: Do not leave your phone in bed while charging, as it can easily overheat and become a fire hazard.

  ·         Charge smartly
  Don't let the battery drop below 20% too often and avoid charging to 100% all the time.

  ·         Adjust screen brightness
  Automatic brightness saves battery by adapting the screen to the environment.

  ·         Limit background activity
  Apps that update in the background can drain your battery unnecessarily. Check your settings and turn off any you don't need.
