At What Percent Should I Charge My Iphone. Answered 1 year ago Author has 13K answers and 1M answer views. Battery University stated that the lithium-ion battery in your phone will last longer if you keep it between 65 to 75 charged at all times.

When the feature is enabled your iPhone will delay charging past 80 in certain situations. If an update is available connect your iPhone to Wi-Fi attach the charger to your Apple Watch make sure it has at least 50 charge and update wirelessly. Ive done that for YEARS and my battery life has maintained itself quite well.
Do not deplete the battery to low levels.
Depending upon the length of time between when the iPhone was made and when it is activated your battery capacity may show as slightly less than 100. The Peak Performance Capability measure is more of a Good Not-so-good or Bad scenario. Never leave a phone unused for weeks or months on end without periodically recharging it. Your iPhone charger will charge your iPhone to 80.
