Is it possible to delete app caches to batter battery usage on iPhone

Hello. I have been an iPhone user for many years. I buy a new model iPhone every year. I started to have battery problems with devices after the iPhone 12 Pro. None of my devices after the 12 Pro had as much battery life as the 12 Pro. While I had to charge the 12 Pro every 24 hours, I had to charge the 14 Pro every 12 hours. I had the same problem with the 15 Pro. I am currently using the 15 Pro Max. Even the 15 Pro Max battery cannot last 24 hours. I have talked to Genius Bar many times about this issue. Each time they told me that "when you buy a new device, when you transfer applications between devices with Quick Transfer, the applications are transferred with bugs and errors, this negatively affects battery usage, and the solution will be to manually download the applications one by one to the new device when you buy a new phone." They advised me not to use the Quick Transfer feature. This is a solution that does not suit Apple quality. Is there another way to clear these errors? I would be very happy if you could help me.

iPhone 15 Pro Max, iOS 17

If you mean Quick Start, that does not transfer apps from your old device to your new one. All that is transferred is the app preference data. The apps themselves are re-downloaded from the App Store. While it is possible that there could be issues with data corruption that would cause an app to run excessively, that's not terribly likely. So forgive me, but I think what you've been told is nonsense. Deleting app caches, where possible, will only cause your iPhone to run more as the app rebuilds its cache and hence use up more power.

Now, as to battery life with your current iPhone, we'll need more information about what apps you're running, whether you've looked at the Battery preferences to see what app or apps are taking up the most power, and anything else regarding your usage that we should know about.

I should mention that as smartphones progress, we start to demand more and more of them. So the battery duration you got from your iPhone 12 Pro may have been longer because you push your more recent iPhones harder. No way to know without objective data, now impossible to collect, obviously.

Regards.

Thanks for your explanatory feedback. I spoke to the most reliable people about this issue, the Genius Bar employees. They told me exactly what I said more than once. I am very confused. I remember that Quick Start works as you said. There is no abnormality in the battery usage of the applications. The only solution they told me is to reset the phone to factory settings and download the applications one by one. They said this is normal on devices that are loaded from Quick Start or iCloud backup.

I won't get into a debate with Genius Bar employees' statements beyond what I said above. But what you report as the life of your iPhone's battery is not what I would consider unusual. I've never had my iPhone last 24 hours without having to recharge it (and letting a lithium-based battery regularly fully discharge is very bad for its overall lifespan). Apple has some additional tips here that you can consider:

tbh storage doesnt affect battery. but you it depends on your usage. if you watch videos or listen to songs or play games on your phone, it'll drain faster.
