An inquiry that reaches us after every iOS update, the device battery is draining quickly, the device has become slow, the device is heating up to a large degree even without intensive use. Some are quick to blame the new update as the reason, but there are many other reasons why you may notice that your battery drains a little faster in the days after the update. In this article, we mention some of the reasons that lead to battery drain and some problems related to this after the update to iOS 16 and how you can handle it.

Photos app in iOS 16 update

The Photos app on iPhone applies machine learning algorithms to recognize your photos and videos. It uses the processor to run these complex processes and thus consumes battery life.

And in the ‌iOS 16‌ update, specifically, there's a new feature, Duplicate Photos, that uses processing on your iPhone to browse through the thousands of photos on your device and identify potential duplicates, and this process can take time and as a result drain battery power.

The more photos and videos you have, the more time it will take for the classification process to complete. As Apple suggests, the best course of action is to leave the iPhone connected to the charger overnight while connected to a Wi-Fi network. This will allow the Photos app to process your photos and videos while connected to power, which will take some strain on the battery. The process may take several days, if not weeks, depending on the size of your library.

Spotlight Search Indexing

Spotlight search on iPhone is a powerful way not only to search for apps and contacts, but also a place where you can search for content within apps, such as emails, messages, maps, photos, and more.

To provide search results for content within your apps, the iPhone needs to index all the content in all of your apps using on-device processing, which also consumes battery life. This can be a long and untracked process, but it happens in the background while you are using and charging your iPhone.

And while there's no way to keep track of the process, you might be able to make it a little easier. Under Settings -> Go to Siri & Search, you can disable Spotlight's ability to search within individual apps. And if there's an app you might not want to index, you can disable Show Content in Search to prevent iPhone from indexing that app, which can help save some battery life.

Your apps need updating

Automatic updates of apps you have installed can have an impact on battery life. Especially after a major update like ‌iOS 16‌, apps still need to be updated to support new technologies and features.

In the coming days and weeks, developers will update their apps to support ‌iOS 16‌ and its new features. Old apps that have not been updated during the trial periods of iOS 16 update to support the new may also cause some battery drain because they may use old tools and codes that are not compatible with the new updates.

Restarting the iPhone can solve many problems

It's always a good idea to restart your iPhone every now and then. Sometimes, after performing a major update, your iPhone may malfunction, and a simple restart can resolve it and return your battery life to normal.

Another thing to remember is that the iPhone battery, like all lithium-ion batteries, loses its capacity over time. You have. Knowing when you're due for a replacement usually depends on you, how you use it, and what you want, but if you don't want to change yourself, iOS will warn you if your battery needs to be replaced.
