Learn why ⇢ the battery in your iPhone drains too quickly for details.


All rechargeable batteries are consumable components that become less effective as they chemically age.


Recent software updates can accelerate that process by adding features that consume more power.


As lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in shorter amounts of time before a device needs to be recharged.


Li Ion (Lithium Ion) batteries have recharging capabilities; however there are limits.


Temperature Effects on Li Ion Battery Life:

  • Capacity loss in standby applications is largely determined by temperature
  • Annual capacity loss tends to decline as the battery ages
  • 80% remaining capacity is generally not the end of a lithium battery's useful life, but recommended by Apple for replacement


I recommend to slow charge your iPhone to maximize the charge capacity, battery health and efficiency. ⚡️🔋


NOTE:
Temperature: Charge above -30°C and Discharge below 55°C.

Apple won’t replace the battery until it reaches 80% capacity.

Thank you for the photo.


Troubleshooting iPhone Charge:

Visit the following links for tips on troubleshooting this...

I. Try what is on this Link: If your iPhone, iPad, or iPod touch won't Turn on or is Frozen - Apple Support


II. Viewing the Battery Health:

Apple recommends you get a new battery, once the Battery Health reaches 80% or lower. So, what's the percentage shown? When the Battery Health is 80% or lower, it is time for a new battery.

  1. Go To: Settings
  2. Tap: Battery
  3. Tap: Battery Health
  4. View: [the percentage]
  5. Is it 80% or less?  If so, it is time for a new battery.


III. Perform a Restart:

Try Force Restarting your iPhone. Save any information that need be. Then perform the restart.

Go Here: Force Restart iPhone - Apple Support


IV. A Few Apple Support Sites that May Help:
