Some iPhone 15 series users were noticing that their phones were burning through one percentage point of battery for every minute while they were overheating. For example, five minutes on Instagram (one of the apps that have reportedly caused iPhone units to become too hot to handle) reduced the battery life by five percentage points. Ten minutes on the app would wipe 10 percentage points of life off of the battery.
If you look at the chart, you’ll see that most iPhone models respond to iOS updates together as a group. So if the next update does improve the battery life of the new models, odds are that your older iPhone will see some improvement as well. How much of an improvement? All we can say at this point is that your mileage may vary.
