With the iPhone 15 and iPhone 15 Pro , Apple added anew stamp battery direction featurewhere users can send those sound to a level best of 80 percent instead of 100 . It ’s also possible to view the institutionalize Hz in the battery place setting . These feature have carried over the the recently free iPhone 16 card .
Why block charging at 80 percent ? It has to do with battery interpersonal chemistry and the effects of bear down over the long haulage . A lower percentage results in fewer full charging cycles , which helps continue the viability of the stamp battery . But file to 80 percent means you effectively have less bearing on your phone for your daily utilisation . So the daily ritual killing worth the long - term impression ? We wanted to discover out .
Macwelt ( Macworld ’s sis web site in Germany ) accommodate a survey on Facebook Germany , asking readers to post screenshots of their battery stage setting and enter their charging behaviour – whether they always or almost always charge to 100 or only to 80 percent . In less than 24 minute , we received more than 100 useable responses .
To visually measure the influence of charging behavior on battery health , we have presented the responses in a combined box and Beeswarm plot .
The two colors or line on the Y - axis vertebra exemplify the data degree in the two class , people who only charge their iPhones to 80 pct and those who charge them to 100 percent . The routine of Department of Transportation show how many people with the various battery capacity we bet in each category . We counted 56 exploiter who charge their iPhones to 100 percentage and 46 users who only charge to 80 percent . The two groups are not the same size , but close .
The superpose box in the diagram show the accumulative analyses of the data . The box in the 80 per centum category tends more towards the boundary of 100 percent capacity – it appears that the substance abuser who charge their iPhones to 80 percentage tend to have a salubrious battery in the long terminal figure .
We try out this hypothesis using a T - test , a coarse statistical method acting to prove that two main group differ significantly from each other . If the phosphorus - note value is less than 0.05 , ( less than 5 percent ) , the two groups dissent significantly . If the P - value is higher , the component under investigation ( in our case , the charging behavior ) does not influence the data collected .
We calculated the T - test once with the integral 102 data point points in the table and obtained a atomic number 15 - value of 0.047121 ( 4.7121 percent ) . In the second calculation , we filter out all information points where the commission cycles were less than 140 , as the battery can not be expected to age significantly up to 140 charge . Here we obtained 89 data point points , six data point points less in each category . But even with this data , the measured P - economic value was 0.047547 ( 4.7547 percent ) . We can therefore say that charging behavior has a statistically significant influence on battery wellness and longevity .
establish on our data , it can be sound out with certainty that user who do not charge their iPhones to 100 percent are conserving the battery through this deportment . The maximum electrical capacity of the battery decreases somewhat more slowly when load to 80 percent than when charging to 100 percent .
