Released in 2018, the Series 4 is now several years old, andApple Watch Series 4 Battery aging is a common phenomenon in Apple Watch Series 4 devices.

Aging Factors:

Chemical Age: This is the most significant factor. Even with minimal use, battery capacity will naturally decrease over time.

Charge Cycles: A complete charge-discharge cycle reduces capacity. The Series 4’s battery is designed to retain up to 80% of its original capacity after approximately 500 full charge cycles.

Usage Habits: Prolonged use or storage in extreme temperatures (too high or too low) accelerates aging.Apple Watch Series 4 Battery

Maintenance and Optimization Recommendations:

Update System: Ensure watchOS is up to the latest version. Apple typically includes battery management optimizations.

Enable “Optimize Charge Limit” (if prompted): The watch learns your charging habits and delays charging above 100%, reducing the time the battery spends at full charge and thus slowing aging.

Avoid Extreme Temperatures: Especially avoid prolonged charging or use in high temperatures (such as inside a car under direct sunlight).

Use Power Saving Mode Mode Appropriately: When the battery is extremely low and cannot be charged, you can temporarily useApple Watch Series 4 BatteryPower Saving Mode” to extend usage time.

Normal Use, No Excessive Maintenance Required: Modern lithium-ion batteries do not require complete discharge and recharging; charge whenever needed.

About the “Apple Watch Series 4 Battery Health” Feature

Apple Watch Series 4 running watchOS 7 or later has a “Battery Health” feature similar to that on iPhones, which you can view directly on your watch.

How to View: Open “Settings” on your Apple Watch.

Scroll down and tapApple Watch Series 4 Battery

Tap “Battery Health”.

You will see two key metrics:

Maximum Capacity (%):

Meaning: Measures the capacity relative to a brand new battery. As the battery’s chemistry ages, its capacity naturally decreases, resulting in shorter battery life per charge.

Health Status Interpretation:

100% – 80%: Normal range. The Apple Watch Series 4 Battery is in good health.

Below 80%: The battery is significantly aged. At this point, the system may display a “Battery health is declining” message and may enable “Optimize charging limits” to protect the battery. While the watch will still function, battery life will be significantly reduced.

If the Apple Watch Series 4 battery is severely aged: When the watch unexpectedly shuts down, the system may automatically enable “Performance Management” (i.e., throttling) to maintain stability and prevent further shutdowns. A related message will be displayed here.

Samsung Galaxy Watch 4 Battery: Impressive Battery Life. The battery capacity of this smartwatch is expected to be roughly the same as its predecessor. Samsung will officially unveil the Galaxy Watch 4 at the upcoming Galaxy Unpacked event. With just over a week until the Samsung Galaxy Unpacked event, we are still getting more information about this upcoming device. Recent leaks suggest that the Galaxy Watch 4 will have a stunning design.

Battery life is expected to be one week.

Shortly after real-world images of the Galaxy Watch 4 Classic leaked online, WinFuture published the expected specifications of the upcoming smartwatch, claiming that, according to various sources, the Samsung Galaxy Watch 4 will have a Samsung Galaxy Watch 4 Battery life of “up to seven days.”

This seems like an impressive achievement for a Wear OS device, easily rivaling some of the best Android smartwatches, such as the Mobvoi TicWatch Pro 3 GPS, which lasts about three to four days in “smart mode.” However, it’s currently unclear whether the Galaxy Watch 4 will need to be in a low-power or hybrid battery mode to achieve seven days of battery life. Smartwatches like the Fossil Gen 5 have multiple battery modes that help extend battery life, which could be the case for the Samsung Galaxy Watch 4.

Samsung Galaxy Watch 4 Battery life, lasting only slightly over a week in time-only mode. In comparison, the TicWatch Pro 3 GPS can last up to 45 days in basic timekeeping mode.

If the Galaxy Watch 4 can last seven days in full smartwatch mode or hybrid battery mode, it would be quite impressive for Wear OS. This upgrade is expected to improve the performance and battery life of the Samsung Galaxy Watch 4, so this possibility is quite likely, especially considering the watch is rumored to feature a 5nm Exynos chip.

Other specifications of the watch include 1.5GB of RAM and 16GB of storage, IP68 and MIL-STD-810G military-grade certification, 5ATM water and dust resistance, Bluetooth 5 support, and optional LTE connectivity. It is also said to feature all the usual smartwatch sensors, as well as some less common ones. According to reports, the Galaxy Watch 4 will come in two versions: a standard version and a classic version, with sizes of 40/44 mm and 42/46 mm respectively. The smaller version will feature a 1.19-inch AMOLED display, while the larger version will have a 1.36-inch AMOLED display, both protected by Corning Gorilla Glass DX.Although not yet officially confirmed, we may soon see Samsung release its next-generation flagship Wear OS smartwatch.
