iOS 16.2 Causing Battery Drain On Apple Watch: How To Fix?

Apple Watch users have complained about the battery drain after iOS 16.1 update. The Watch charged at 99%, and the charge dropped by 8% in four hours. Many iPhone users have reported the same news on the 12 Pro and 14 series. The iOS 16.1 has affected the battery life in iOS devices and the Watch series. Here are viable solutions to resolve the battery drain issues in the iOS device and watchOS.

iOS 16.2

Why Is Apple Watch Battery Draining After Software Update?

Apple spends billions on the R&D team. The manufacturer conducts various tests on the battery and its performance impact. We should learn about how the company works and how they plan things for the next generation of products. We have shared a few reasons why your iPhone and Watch are getting worse battery life than before.

Battery Degradation:

Apple has launched its chipset for the Mac computers, iPhone, iPad, and Watch. However, the manufacturer doesn’t have a new generation battery technology. The traditional Li-ion technology powers Apple devices. Everybody knows that Li-ion batteries degrade with time.

Software Bugs:

Apple has a huge team working in the headquarters. The in-house team releases newer software versions for the older hardware. The software development team can make mistakes that can lead to problems. Nobody is perfect in this world.

Software Glitch:

One minor glitch can drain the battery from 99% to 10% in a few hours. One user shared that the GPS drained the battery in the Watch 6 model. The software glitch misused the hardware in the Watch and drained the life out in a few hours. Identify the culprit in the iPhone and Watch.

Background Tasks and Indexing Processes:

The watchOS and iOS run multiple background processes all the time. These processes need a power source to run the tasks. The battery is depleting much faster than estimated. Users can avert power consumption to some extent.

Voice Assistant:

Siri is a powerful AI assistant for Apple devices. However, the voice assistant consumes a lot of energy for the facility. Older Watch models and iOS devices should turn off the feature and focus on getting a better battery life.

Unused Applications:

How many applications did you install on the iPhone and Watch? The unused apps running in the background consume energy to provide the latest information. The Apple device is wasting power on useless apps. Delete them from the device and save yourself from additional power consumption.

Incorrect Settings:

We customize the iOS and watchOS devices to suit our needs. If you turn on the GPS (for maps) and leave it without closing the application, it will drain the battery. Close the Maps application and turn off the GPS when you don’t need it.
