I was glad to upgrade the iPhone 14 Pro to the new iPhone 16 Pro from the first day when the devices were put up for sale. After exactly 12 days of use, the joy began to disappear when I started to find that the iPhone 16 Pro battery is consumed very quickly, the autonomy being lower than the iPhone 14 Pro which has a battery health of 87%.
If you are the owner of an iPhone 16 Pro or iPhone 16 Pro Max whose battery is downloaded very quickly, the guide below could be helpful to understand where this problem of low autonomy occurs and what you need to do.

How performance is the iPhone 16 Pro battery compared to iPhone 15 Pro and iPhone 14 Pro?
The performance of a battery is given by its life. Specifically, iPhone battery life is a measure of phone autonomy between two charging cycles. The time period in which the battery of the phone reaches from 100% to 0% under normal conditions of use. This period of use between two charging cycles begins to decrease over time, as the battery is used and its health decreases.

According to Apple's words and the technical specifications of new devices, the iPhone 16 Pro has an energy storage capacity of 3,582 mAh, 9.4% higher than the one present on iPhone 15 Pro (3,274 mAh). With a full battery charge, the iPhone 16 Pro should be up to 27 hours in video playback, about 4 hours more than iPhone 14 Pro and iPhone 15 Pro. In audio playback, the autonomy promised by iPhone 16 Pro is up to 10 hours, compared to previous generations, reaching up to an autonomy of 85 hours (3 and a half days).
All these data are in accordance with the technical specifications and comparisons between the three iPhone models, offered on Apple's official website.
Why is the iPhone 16 Pro battery consumed very quickly?
If you are the owner of an iPhone 16 Pro and you find that the battery life is reduced and it does not keep as long as you have expected, you must consider a few elements that can determine its low autonomy under normal use conditions.
ICLOUD data synchronization leads to rapid discharge of iPhone 16 Pro
The iPhone battery is downloaded very quickly in the first days after installing your device and connected it to your Apple account. You will notice that after you have connected your Apple account for the first time to the new device, it will warm up and the battery charge level will drop very quickly.
If you use the iCloud service for storing photos and videos, it will be a few days until they are downloaded, indexed and sorted in the native photo application (Photos). Even if some optimization tasks will be done when the iPhone 16 Pro is charged at night, when you access the photo gallery will start downloading the contents from iCloud, which will take a quick consumption to the battery and to heating the device.
The same will also happen with other Apple applications that use data and settings in iCloud. Their download will make the iPhone 16 Pro battery consume very quickly in the first days of use.
iOS 18.1 Beta downloads the iPhone 16 Pro battery very quickly.
Any beta version of an operating system comes with many inconveniences, one of them being the quick discharge of the battery of the device. After testing a few days iOS 18.1 (beta), I found that the iPhone 16 Pro battery is consumed very quickly, the autonomy being less than one day, under normal use conditions.
If you are in this situation, the solution is to give up the iOS 18.1 (beta) version and return to the final version iOS 18. You must keep in mind that this downgrade involves reinstalling the iOS operating system, which will lead to all data from the device, if they are not kept in iCloud or you do not have a backup.
In my case, this was the solution. After giving up iOS 18.1 and reinstalled the iOS 18, the iPhone 16 Pro battery started to hold more from the first day, even if the synchronization of the data in Iloud has not yet been finished. Most likely, Apple Intelligence, the top feature of iOS 18.1 is not so smart as to effectively use the energy resources of the iPhone 16.
Do you have this problem with the autonomy of the iPhone 16 Pro / Max battery?
