Every iPhone user is concerned with battery life , and for good cause . Our phones are oureverythingthese days , and when the battery dies we feel cut off from the world and ineffectual to capture the consequence . With the iPhone 15 , Apple is provide a unexampled option to help increase battery longevity – not how long a exclusive boot survive , but to reduce the natural degrading common to all rechargeable batteries .
In iOS 13 , Apple sum a newOptimized Battery Charging featurethat , when enabled , look at your past iPhone use chronicle to pause commove at 80 percent when the system determines you ’re improbable to postulate more than that before you bear down again . That ’s dainty , but you ’re still leaving it up to the system .
With the iPhone 15 ( all models , include Pro ) , there ’s an additional choice in options > electric battery > Battery Health & Charging > Charging Optimization . The new80 % Limitoption will lay off your iPhone from charging when it pass on 80 percent of full mental ability , all the prison term , every time .
In addition , you could open configurations > General > Aboutand find a Modern Battery section that shows your battery ’s manufacture date , engagement of first usage , and cycle count . This could be useful data for those getting third - party repairs or replacing for their batteries , or deciding some yr down the line if the battery need replace . All iPhones record this data point , but you have to employ third - party apps to easy read it or jump out through some hoops like pasting your iPhone Analytics Data into Notes and strain through it . This could be particularly utilitarian after the iPhone 14 Pro Max appeared to sufferabnormal shelling degredation .
Why would a person want to confine charging to 80 percent ? Well , rechargeable batteries degrade over time through normal use and are able to view as less billing , which intend short battery life story . They degrade much quicker when under uttermost thermic tenseness , and when kept in a fully - charged state .
For model , this is why all mod electric cars promote drivers to limit charging to 80 - 90 pct for daily drive and provide configurations to do so , with full 100 percent point only for longer trips .
user like me who work at a desk with ready access to a battery charger and rarely drop below 40 percent on a distinctive Clarence Day would be better off setting a hard charge demarcation line of 80 percentage , as long as they recollect to turn it off on those day when they ’re potential to have a heavy - habit day away from the battery charger .
It is , of class , just an option — like optimise Battery Charging , it can be enable or handicapped at will to give users more control over battery animation and longevity .
The only question we have is : why is this useful feature of speech confine to iPhone 15 models ? for sure there are plenty of existing iPhone owners who would value this option in a software update , and it seems trivial enough to go through . Maybe we ’ll see it in iOS 17.1 .
