iOS 16/17 iPhone draining battery can be attributed to many factors like bus issues, background running apps, auto-updates or watching videos, etc. As a result, it's essential to take a step back and observe the situation appropriately. Some of the most prevalent errors are listed below.

1 Photo App

There are several new options, such as Duplicates, exist in the default Photos app. With iOS 16/17, searching through all your images for duplicates is possible. iOS might take many days, if not weeks, to finish mapping your whole library if you have a vast collection. Apple claims that the detection occurs when an iPhone is locked and plugged into a power source. Battery life may be prolonged by disabling these photo apps and other battery-draining features.

These Photo apps may make your screen seem stunning with animations that are captivating to the eye. It's important to remember that active wallpapers consume more battery than static wallpapers.

3 Apps that Needed an Update

iOS 16/17 facilitates a seamless experience by enabling the automatic installation of applications on devices sharing the same Apple ID.

Using an app for more extended periods will drain the battery faster. If you have been using your device for extended periods with the screen on, you may have noticed that your battery drains quickly.

However, if you're using your phone like before, the issue is likely not the device itself. The best action is to find out which app is draining your power without worrying about the probable causes.

Another bad habit while using your iPhone is to charge your iPhone when battery below 15%. This could cause battery damage thus leading to battery drain fast.

Part 5: Small Tips to Charge Your iPhone Properly

Finally, you learned why iOS uses so much battery and the most effective way to conserve it. The optimal way to charge your iPhone can extend its battery life. While charging your iPhone is essential, it is equally as essential to ensure that you are not doing anything else to damage the battery of your iPhone. Therefore, to protect the overall health of the battery in your iPhone, here are a few pointers:

1 Avoid Overnight iPhone Charging

If you don't want to charge your phone in the morning, wake up with a full battery. Therefore, you can charge your iPhone overnight. However, this is not a good practice, regardless of whether you have an Optimized Battery Charging set for your iPhone. Charging your phone overnight might damage the battery.

2 Stop Charging 100% Always

Avoid charging your iPhone to 100% and never below 25%. To protect your iPhone's battery, keep it between 30% and 80%. Always charge your iPhone to at most 80 percent rather than 100 percent.

Optimized charging can fully charge your phone by morning. It stops charging the phone at eight percent and restarts it before you unplug the charging wire.

3 Stay Cool

High temperatures can damage iPhone batteries. Avoid heavy iPhone duties like playing games or using the camera in hot weather, especially when charging.

If not, maybe causing your iPhone, especially iPhone 15 overheating, dimming the screen and limiting background tasks. Apple recommends 32°F to 95°F (0°C to 35°C) for the iPhone.

In addition, it's not good to use fast or wireless chargers that might cause your iPhone to overheat and harm the battery. Instead, charge your iPhone with the charger that comes with it or a third-party (WooTechy iPhixer) charger that Apple has approved.

If you follow these guidelines, your iPhone's battery life will be significantly prolonged, and you can stay connected everywhere you go.


Many iOS 16/17 users are frustrated with the rapid depletion of their device's battery and want Apple to implement a solution quickly.
