How many days does the Xiaomi Watch S1’s battery life actually last after 3 months of use?

The Xiaomi Watch S1, released at the end of 2021, is it still competitive in terms of Xiaomi Watch S1 battery life? I conducted an in-depth test after wearing it for three months, and here’s my take.

First, the hardcore data: The Xiaomi Watch S1 has a built-in 470mAh super-large battery. The official claim is 12 days of typical battery life and up to 24 days in long-lasting mode. During my first week, I monitored my heart rate, blood oxygen, stress, and sleep with all my monitoring enabled. The battery drained by about 10% to 15% per day, and I only needed to charge it after 9 days, which isn’t too far off from the official claim.

However, one user summarized the pattern: “Basically, I only need to charge it once a week,” while others admitted to charging it “every day and a half.” What’s the difference? The core difference is usage habits.

A colleague of mine runs with GPS on every day and also wears Bluetooth headphones for calls, and his Xiaomi Watch S1 battery was completely drained in just 3 days. Another friend only used it for checking the time, receiving messages, and occasionally swiping their public transport card, and the Xiaomi Watch S1 lasted for over a week. The battery life performance was vastly different. Here are a few tips to optimize battery life: lower the screen brightness, turn off Wi-Fi and GPS, and switch heart rate monitoring from “all-day” to manual mode. In actual testing, the standby current dropped from 85μA to 52μA.

TheXiaomi Watch S1 batterycharging is also worth mentioning. The 10W magnetic wireless charger is very convenient; I can simply place it on my desk to charge whenever I want. In my tests, it charged to about 50% in half an hour and fully charged in less than 2.5 hours. I usually wear it while washing up and having breakfast, and the battery is almost fully charged, so I basically don’t need to set aside time to charge it.

Of course, the Xiaomi Watch S1 also has its “battery life shortcomings.” The official “typical battery life” conditions are rather idealistic: 200 screen activations per day, 100 notifications received, and only 15 minutes of Bluetooth calls per week. This means that if you keep blood oxygen monitoring on all day and make frequent calls, the Xiaomi Watch S1’s battery life will quickly diminish. Moreover, this watch has been on the market for over four years, so if it’s a used unit, the battery is likely already aged, meaning the Xiaomi Watch S1’s actual battery life will only last 4 to 5 days.

If you’re a light user, or happen to find a brand new, stocked unit, the Xiaomi Watch S1’s 472mAh battery, combined with magnetic fast charging, will still offer decent battery life. However, if you’re a heavy user, or considering buying a used unit, it’s advisable to think twice—Xiaomi Watch S1 battery anxiety is even more frustrating than the watch running out of power and shutting down.

A Comprehensive Analysis of the Garmin Vivoactive 3’s Battery Life

Based on the actual experiences of numerous users, the Garmin Vivoactive 3 Smart Watch Battery life  generally aligns with the official specifications; however, certain common scenarios exist:

Light to Moderate Daily Use: With the “Always-On Display” disabled, brightness set to a moderate level, and 30 minutes of daily exercise (without GPS enabled), the watch typically lasts for 5–6 days.

Heavy GPS Use: For activities such as running a marathon or long-distance cycling, continuous GPS usage can sustain the device for approximately 11–12 hours—close to the advertised rating.

Battery Degradation in Older Units: For watches that have been in use for 2–3 years or longer, battery health typically declines. In “Smartwatch Mode,” battery life may drop to 3–4 days, while in “GPS Mode,” it may fall below 8 hours.

How ​​to Charge the Garmin Vivoactive 3 Smart Watch Battery

Charging Method: Use the original or a compatible Garmin-specific clip-style charging cable (featuring 4 metal contact pins). Wireless charging is *not* supported.

Charging Specifications: Input requirements are 5V/0.5A–1A; a standard USB port or a typical smartphone wall adapter will suffice.

Charging Time:It takes approximately 1.5 hours to charge from 0% to 100%. The device can reach about 40% charge within the first 30 minutes.

Charging Indicators:** Once the charging clip is attached, a battery icon will appear on the watch screen; upon reaching a full charge, the screen will display a “100%” notification.

Note: Avoid using “fast-charging” adapters (e.g., 9V/2A or higher voltage) for prolonged charging periods. Although the watch is equipped with a power management IC, low-quality fast chargers may cause the charging cable or the watch’s contact pins to overheat. It is recommended to use a power adapter rated at 5V/1A or lower.

Solutions for an Aging Garmin Vivoactive 3 Smart Watch Battery

If your Vivoactive 3’s battery life has dropped to less than 2 days in “Smartwatch Mode,” or less than 4 hours in “GPS Mode,” this indicates that the battery has significantly degraded. The available solution is:

Battery Replacement: Contact Garmin Customer Support/After-Sales Service. Replacing the Garmin Vivoactive 3 Battery Yourself: The Vivoactive 3 was not designed to have a user-replaceable battery. The process requires disassembling the device—specifically, heating the screen, prying it open, and soldering—and is technically challenging. Therefore, it is not recommended for individuals without prior repair experience to attempt this procedure.

Tested and working! Turning off this one feature on your Apple Watch Series 1 increases battery life from 8 hours to 24 hours

According to actual test data, disabling background app refresh can save an average of about 30% of the Apple Watch Series 1 Smart Watch Battery ower. And most importantly—don’t worry, this won’t affect push notifications at all; it simply prevents apps from silently updating and consuming power in the background.

1. How to turn it off? It’s very simple.

Open the “Settings” app on your Apple Watch → Go to “General” → Find “Background App Refresh”.

You’ll see a toggle button, below which is a list of all installed apps. Each app can be individually configured to allow or deny background refresh. The most power-efficient way is to turn off the master switch, disabling all apps from refreshing in the background at once.

After turning it off, those weather, news, and health apps that were secretly running in the background will all stop.

2. Actual Apple Watch Series 1 battery test results: From 8 hours to 24 hours

After disabling background app refresh for the first time, I specifically conducted a full battery life test:

I removed the watch from the charger at 7 AM, fully charged. I received notifications normally, occasionally checked the time, and raised my wrist to check the time about 20-30 times a day. By 7 AM the next morning, a full 24 hours later, the Apple Watch Series 1 still had 12%Apple Watch Series 1 Smart Watch Battery remaining.

That means the Apple Watch Series 1’s battery life jumped from 8 hours to 24 hours. Not just 1.5 times, but a full 3 times!

What surprised me even more was that after disabling background refresh, the watch’s operation became even smoother—the processor didn’t need to frequently switch between background tasks and foreground responses, making everyday swiping and app opening significantly faster.

3. Power-saving tips for combined use (the effects are even more amazing)

Enable Low Power Mode: Control Center → Tap Apple Watch Series 1 Battery Percentage → Turn On.

Disable Raise to Wake: Settings → Display & Brightness → Turn off Raise to Wake and set the wake-up duration to 15 seconds.

Reduce screen brightness by 1-2 levels: Settings → Display & Brightness → Lower Brightness. This has little impact on daily use but can save a significant amount of Apple Watch Series 1 Smart Watch Battery power.

Turn off ambient noise detection: On your iPhone, go to Settings → Noise → turn off “Measure Sound”.

Regularly restart to clear cache: Restart your watch every 1-2 weeks to allow the system to clear accumulated temporary files and memory fragmentation.

Enable optimized battery charging for your Apple Watch Series 1: Go to Settings → Battery → Battery Health → turn on “Optimize Battery Charging”. This allows the watch to learn your charging habits and avoid prolonged full charging, thus extending battery life.

The biggest culprit for battery drain on the Apple Watch Series 1 isn’t excessive screen brightness, but the master switch hidden in “General → Background App Refresh”—turning it off won’t affect message reception, and it triples the Apple Watch Series 1 Smart Watch Battery  life. Add to that a black watch face, turn off raise-to-wake, lower brightness, and turn off noise detection—who says this old watch can’t perform?

If your Garmin Forerunner 955 Solar battery is low, please turn off these two features

The Garmin Forerunner 955 Solar has two settings that, when turned off, can squeeze out a final few dozen hours of Garmin Forerunner 955 Solar Smart Watch Battery life from the lowest possible level.

The first setting: Turn off “Auto-select Satellite Mode” and force a switch to “UltraTrac”.

Most people don’t know that the default “Multi-Frequency Multi-Satellite” or “Auto-select” mode on the Garmin Forerunner 955 Solar is the number one culprit for battery drain.

Multi-frequency multi-satellite (GPS+GLONASS+Galileo+BeiDou) positioning accuracy is extremely high, suitable for urban high-rise buildings or dense forest environments, but it drains the battery extremely quickly—in real-world testing, it drains about 6%-8% of the battery in one hour. That means a 10% Garmin Forerunner 955 Solar Smart Watch Batterylevel on a Garmin Forerunner 955 Solar will only last for about two hours in this mode. I turned it off, went to Settings → Satellite → Mode → and selected “UltraTrac”.

UltraTrac is Garmin’s power-saving GPS mode specifically designed for ultra-long distances.

After switching to UltraTrac, the GPS battery life of the 955 Solar jumped from 42 hours to over 80 hours. A 10% battery level on the Garmin Forerunner 955 Solar watch can last at least 8-10 hours in this mode.

Second: Turn off “Wrist Heart Rate” + “Auto Blood Oxygen Monitoring”

Many people think heart rate is essential for running, but when the Garmin Forerunner 955 Solar watch’s Garmin Forerunner 955 Solar Smart Watch Batteryis critically low, you have to make trade-offs.

Go to Settings → Sensors → Wrist Heart Rate → Turn off. Also find Pulse Oxygen → Turn off “All-Day Monitoring” and “Sleep Monitoring”.

After turning them off, the watch no longer actively measures heart rate and blood oxygen, only retaining basic step counting and GPS track recording.

After turning off these two settings, the Garmin Forerunner 955 Solar watch, in UltraTrac mode, showed an estimated battery life of 11 hours and 23 minutes with 10% battery remaining.

Since CP4, I’ve set the watch to these settings. Screen brightness is also reduced to the lowest level (5%), Bluetooth connection to the phone is turned off (to avoid power consumption from Bluetooth broadcasts), automatic backlight on/off, and only manual button presses are enabled for data viewing.

The map page is closed, leaving only the most basic “distance + time + pace” data bars. Map rendering is a major CPU consumer; turning it off added about an hour to theGarmin Forerunner 955 Solar Smart Watch Battery life.

Summary: The 955 Solar’s Three Essential Lifesaving Measures

If you find yourself in a situation where your Garmin Forerunner 955 Solar watch has only 10% battery left but you need to complete a long distance, remember these two core settings to disable + one alternative:

Satellite Mode → UltraTrac (saves over 50% power)

Wrist Heart Rate + Automatic Blood Oxygen Monitoring → All Off (saves 20%-30% power)

(Alternative) Disable map rendering, Bluetooth, and automatic backlight

The Garmin 955 Solar is a great watch, but even the best battery can’t withstand mindless default settings. Turning off unnecessary functions isn’t a compromise, it’s wisdom.

Don’t let 10% Garmin Forerunner 955 Solar Smart Watch BatterySolar watch become the reason for dropping out of your next 100km race.

Fantastic! My Xiaomi Watch 9 lasted three days after a full charge, and it still has 80% battery left

Xiaomi Watch 9 BatteryTest: 3 Days of Heavy Use, No Battery Level Expected to Drop

To be honest, before receiving the watch, I was skeptical of the official claims about its long battery life. After all, smartwatches these days have more and more features, and brighter screens; it’s no wonder battery life is so limited. But this time, I was proven wrong.

To test its limits, after fully charging, I deliberately didn’t use any power-saving settings. I kept the always-on display, scientific sleep monitoring, and all-day heart rate monitoring enabled, and even message notifications and several outdoor running records.

Day 1 Night: Before going to bed, I checked the Xiaomi Watch 9’s battery level: 95%. It barely lost any power on the first day, and I wondered if the display was inaccurate.

Day 2 Night: After a whole day of frequently raising my wrist to check the time, receiving WeChat notifications, and wearing it while sleeping for monitoring, the battery still had 88%.

Day 3 Afternoon: This is the third day of use, and the battery level is now at 80%. Three days of heavy use only consumed 20% of the Xiaomi Watch 9 Battery

What does this mean? If you only use it normally and don’t engage in high-intensity GPS-enabled activities, a two-week battery life for this watch might actually be a reality.

Why is the Xiaomi Watch 9’s battery so power-efficient?

This isn’t just due to its large battery capacity, but also the result of optimized hardware and software. Although it has a built-in 470mAh battery, which isn’t the largest for a smartwatch, thanks to its low-power chip and Xiaomi’s Surge OS 2.0 system-level power-saving optimizations, every milliampere of power is used efficiently.

Here are a few tips to further save power and achieve this “insane battery life”:

Choose “Power Saving Mode” according to your needs: If you’re not a heavy user, you can turn on the long battery life mode, turning the watch into a “larger fitness tracker,” effectively doubling the Xiaomi Watch 9’s battery life.

Control “Screen On”: In the app, lower the sensitivity of “Raise to Wake” or turn off Always-On Display (AOD). This is the biggest drain on the Xiaomi Watch 9 Battery

Background Management: Turn off notifications from infrequently used apps, keeping only key notifications like WeChat and phone calls enabled. This keeps things quiet and saves power.

After using it for a few days, the most noticeable difference is: I forget where I put my charger. With other watches, I always had to constantly monitor the battery level, panicking when it dropped below 30%. Now? On a three-day business trip, I didn’t even bother bringing the charger. This feeling of not having to worry about the battery at all allows a smartwatch to return to its essential function as a “watch”—always there, never disconnected.

If you’re also fed up with smartwatches that require daily charging or even twice a day, the Xiaomi Watch 9 might truly be the answer to yourXiaomi Watch 9 Batteryanxiety. After all, a watch is meant to serve you, not be pampered by you every day.
