Try charging your iPhone to 100% capacity. ⇢🔋


About Battery Performance:

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.


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


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


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


NOTE:

Capacity loss in standby applications is largely determined by temperature.


Charge above -30°C and discharge below 55°C for best results.
