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


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.

Im realised it as what you said base on age reason. However.. im feel really surprise on battery consumption before if comparing with ios 15.7. Its much better on battery comsumption.


Normally i had recharge it once the battery level reduce to 20% and i will charge it until 80-85%. it will sustaining me up to next day to recharge again with ios 15.7. But now with ios 16… it getting worst. Same goes to my son phone too, he need to charge it more than 2 time a day for daily usage.


May be you can survey with other users iether my statement is nonsence or you can think it back base on my genuiene statement. Anyway im really love and much appreciate to Apple since iPhone 3 and never ever turn to other product. Pls appreciate it to your loyalty customer, tq👍
