Check iPhone battery health

The battery of a smartphone is gradually becoming less and less effective. It is then no longer possible to fully charge the battery. As a result, the battery lasts less long and has to be recharged faster.

It is possible to view the health of the iPhone battery. In the Battery health option, Apple lists maximum capacity and peak performance. We explain what these terms mean later in this article. First, let’s list the steps to access the Battery Health option:

• Tap on Institutions.
• Scroll down a bit and tap Battery.
• Tap on Battery condition.

Maximum capacity measures battery capacity relative to a new battery. A brand new battery has 100 percent capacity. As the battery ages, its capacity decreases. As a result, the battery must be recharged earlier. Typically, an iPhone battery retains up to 80 percent of its original capacity when fully charged 500 times.

If the battery capacity has become too low, the iPhone can no longer always perform well. The phone will then not be able to deliver maximum performance. At the risk of the phone freezing and turning itself off. Apple can then turn on the power management feature. This deliberately slows down the iPhone to prevent the phone from turning off unexpectedly again.

Under ‘Peak performance’ you can see the status of the battery quality.

Below is an overview of the options that can be found under ‘Peak performance’:

• Your battery currently supports normal peak performance.
  In this case, the battery is still working and the power management function is not enabled.
• This iPhone shut down unexpectedly because the battery was unable to provide the needed peak power. The power management feature has been applied to prevent this from happening again.
  The battery no longer works properly and Apple makes the phone slower. Don’t you want that? Then click on Turn off. Keep in mind that the phone can be switched off again.
• This iPhone shut down unexpectedly because the battery was unable to provide the needed peak power. You have manually disabled the power management feature.
  This option shows after you clicked ‘Disable’ in the previous option.
• This iPhone cannot determine the battery condition. An Apple Authorized Service Provider can repair the battery.
  This message can be displayed with an incorrectly installed battery or an unknown battery component.
• The condition of your battery is significantly reduced. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity.
  This last option indicates that the battery’s condition has deteriorated considerably. This does not mean that use is dangerous, but that you may experience discomfort when using it. The phone is probably slow to use.
