When yourApple Watch Ultra 4 battery life is significantly reduced, first check the battery health: Open “Settings > Battery > Battery Health” and check “Maximum Capacity”. Apple’s official threshold is below 80% for battery service eligibility; even 81% may result in rejection.
If it’s already below 80%, third-party repair is a cost-effective option.
You can replace the Apple Watch Ultra 4 battery separately; it’s fast, but you need to choose a reputable vendor and confirm the battery brand and warranty policy.
Replacing the Apple Watch Ultra 4 batteryyourself is high-risk and not recommended.
iFixit gives the Ultra 4 only a 4/10 repairability rating. The screen is held in place with strong adhesive and needs to be pried open with heat; the underlying ribbon cable is fragile, and the screen can be ruined if not handled carefully.
Official replacement process: Schedule an appointment through the Apple Support app; send it in for inspection; unpair and back up your iPhone beforehand; pay after confirming the service unit at the store.
DailyApple Watch Ultra 4 battery Maintenance: Keep “Optimized Battery Charging” enabled (permanently enabled by default on Ultra), which reduces the time required for a full charge to reach its maximum capacity. Avoid high temperatures and direct sunlight; Apple recommends temperatures between 0°C and 35°C. Update your system regularly to optimize Apple Watch Ultra 4 battery management.
In short, when the battery health drops below 80%, Apple offers a full replacement for a fee. Third-party replacements are cheaper, but careful selection is crucial, as DIY repairs carry extremely high risks. Choose a method based on your budget, time commitment, and risk tolerance, and cultivate good habits to slow down Apple Watch Ultra 4 battery aging.

It operates at 3.7V, with a total energy of approximately 0.56Wh, and is a lithium-ion rechargeable battery.
Official Garmin Fenix ​​5S Battery Life
The Garmin Fenix ​​5S watch boasts the following Garmin Fenix ​​5S Smart Watch Battery life: up to approximately 9 days in smartwatch mode, approximately 12 hours in GPS training mode, approximately 28 hours in UltraTrac power-saving mode, and approximately 14 hours with wrist heart rate monitoring enabled in GPS mode. Actual battery life is affected by screen brightness, sensor activation status, and satellite positioning frequency.

Battery Life Degradation
After approximately 3 years of normal use, the Garmin Fenix ​​5S Smart Watch Battery life of the Garmin Fenix ​​5S watch will noticeably decrease. Some users have reported that a Fenix ​​5S that had been used for several years ran out of power at around 18 miles (29 kilometers) during a marathon training session. Since the Fenix ​​5 series is discontinued, official battery replacement services for the Garmin Fenix ​​5S watch may no longer be provided, and users will usually need to handle this themselves.
Replacement SolutionReplacing the Garmin Fenix ​​5S watch battery is relatively easy and does not require soldering. The only tools needed are a T6 screwdriver and a plastic pry bar. Steps: Remove the four screws on the back, open the back cover, disconnect the old battery connector, insert the new battery and reconnect it, and finally tighten the screws back on.
Garmin Fenix ​​5S Watch Battery Maintenance Recommendations
Charge the Garmin Fenix ​​5S Smart Watch Batterywhen it drops to 20%-30%, instead of charging it to 100% every time.
Avoid charging in high-temperature environments.
When not wearing the Garmin Fenix ​​5S watch for extended periods, maintain the battery level between 40% and 60% and store it in a cool, dry place.
Avoid over-discharging, as this may cause irreversible damage.
In summary, although the Garmin Fenix ​​5S watch has a small battery capacity, it achieves long battery life through low power consumption. Consider replacing the Garmin Fenix ​​5S Smart Watch Battery after approximately three years of use. Third-party solutions are inexpensive, and DIY replacement is also feasible.

Garmin Venu 3 review: Design The Garmin Venu 3 comes in two main versions: the standard version I have, which comes with a 45mm case, and the Venu 3S, which comes with a 41mm case and is designed for those with thinner wrists. The 45mm Venu 3 I reviewed has a longer Garmin Venu 3 battery life, rated for up to 14 days, while the 41mm model is rated for up to 10 days, but both are worse than the Apple Watch. The Venu 3 also has a high-resolution OLED screen with 454 x 454 pixels. This used to be a hallmark of the series. Among Garmin watches with OLED screens, the Venu was a good choice, and it was affordable.
