How long does the Apple Watch Series 9 and Apple Watch Ultra 2 battery last?

Apple Watch Series 9

Important points in choosing one product Especially when it comes to electronic devices, it is Battery life In fact This is one of the elements that Apple tries to maintain from model to model across all of its devices. Even more important is the battery in the Apple Watch, Apple’s big smartwatch. It is a device for use in everyday life. With the release of the Apple Watch Series 9 and Apple Watch Ultra 2, we saw that there were some related changes. Battery independence We analyze every model after the jump.

See battery basics.

The Apple Watch is a small but very capable device. Many times we have talked about the importance of these two aspects within the power of a device. On the one hand hardware That changes and advances from device to device. Within this field, we introduce chips, battery capacity and architecture, materials, integrated circuits, and much more. Many times, the availability of new hardware means a shift in independence: More resource usage by the hardware means more battery life. Either do that or we make the hardware as efficient as possible while maintaining battery consumption. On the other hand, We have software In this case, watchOS is 100% hardware-based, which determines how the Apple Watch works. Thanks to its powerful software, we can use the device every day.

at Rechargeable battery Like the Apple Watch, they are a consumer product that is available just like anything else. Limited lifespan According to Apple, over time Reduced capacity and performance We see this with other devices like the iPhone or iPad that have reduced capacity. And we need to charge it more often. The Apple Watch is similar but is a smaller device and has a smaller battery.

In the case of the Apple Watch battery, it’s technology. lithium ion These batteries allow for faster charging. Longer service life and has more energy density This extends the duration in a lighter format. This allows for further hardware development without having to worry about the internal structure of the watch.

Here’s how much Apple Watch battery life lasts.


Very important part for The Apple Watch’s autonomy is its hardware. Devices with powerful hardware will increase battery life. But let’s not fool ourselves, another important part is software, and Apple knew this even last year. watchOS 9 integrates battery saver mode. In an effort to make the watch’s battery last longer,

For comparison and characteristics of each watch, we would like to distinguish between Battery life in normal or “real” use and how long Low Power Mode is enabled. With this information and everything else Apple has offered over the years, We therefore received the following release:

  • Actual duration:
    • Apple Watch Ultra 2: up to 36 hours
    • Apple Watch Ultra: up to 36 hours
    • Apple Watch Series 9: up to 18 hours
    • Apple Watch Series 8: up to 18 hours
    • Apple Watch Series 4, 5, 6, and 7: up to 18 hours
  • Low power period:
    • Apple Watch Ultra 2: up to 72 hours
    • Apple Watch Ultra: up to 60 hours
    • Apple Watch Series 9: up to 36 hours
    • Apple Watch Series 8: up to 36 hours
    • Apple Watch Series 4, 5, 6, and 7: up to 36 hours
Apple Watch Series 9

The new Apple Watch Series 9 and Ultra 2 have been a success. Maintain standard battery life However, the Series 9 failed to increase its time in low-power mode. But it will not only match data related to Series 8, but Ultra 2. Up to 72 hours with low power mode and for many users Is this reason enough to upgrade from Ultra to Ultra 2? Do you think it’s worth it?

Why is my Apple Watch battery lasting less?

As we saw at the beginning of the article. The battery life of all devices will degrade and its capacity will change over time. At The capacity of lithium-ion batteries decreases over time.This immediately affects the charging time and power.

This is because of what is called chemical aging Other factors such as Maximum resistance are factors that influence this decline. For example, the Apple Watch relies on the battery for optimum performance, but Higher resistance can affect the immediate power dissipation.. at Battery resistance is the flow resistance of the battery when passing through the device. As the battery ages The resistance to charging transmitted to the Apple Watch increases, that is, the battery resistance increases.

If your Apple Watch is less functional You will see your battery drain faster or need to be charged more often. These are signs that High battery drain This isn’t surprising considering they biodegrade just like any other consumer product. In fact, if you’re near an official Apple Store, You can go there to see if there is any possibility of change. new battery It will restore the correct operation of the device. If you don’t have a store nearby You can make inquiries from Apple technical support directly from the official website.
