Asus ZenBook S 13 Battery Health Maintenance Methods

I’ve reorganized the methods for protecting the ASUS ZenBook S 13 Laptop Battery as follows for your convenience:

Core Tool: Utilize MyASUS’s “Battery Health Charging”

This is ASUS’s core feature for battery protection, and it applies to the ZenBook S 13 as well. You can find “Battery Health Charging” in the “Device Settings” section of ASUS Manager MyASUS. Choose the appropriate mode based on your usage scenario. Optimal Maintenance Mode: Charge to 60% for long-term use with the power adapter connected (e.g., in the office, with an external monitor). Three Daily Maintenance Tips

Besides software settings, daily usage habits are also crucial:

Controlling the Optimal ASUS ZenBook S 13 Laptop Battery Range

Daily Use: If convenient, try to keep the battery between 20% and 80%. This is the most comfortable operating range for lithium batteries, effectively slowing down aging.

Long-Term Storage: If you plan to not use the computer for an extended period (e.g., more than two weeks), it is recommended to charge (or discharge) the battery to around 50%, then shut down and store it. The ambient temperature should ideally be between 5℃ and 35℃. And remember to top up the battery to 50% approximately every 3 months.

Perform regular battery calibration.

Calibrate the battery every one to two months to make the system’s displayed battery level more accurate:

Step 1: Fully charge theASUS ZenBook S 13 Laptop Battery to 100% and keep it plugged in for 1-2 hours.

Step 2: Unplug the power cord and use the computer normally until the battery is completely depleted and it shuts down automatically.

Step 3: After letting it sit for a few hours, fully charge the battery to 100% again.

Avoid “Two Highs”: High Temperature and Full Charge

Avoid High Temperature: High temperature is the “number one killer” of lithium batteries. Try to avoid using the computer in excessively high ambient temperatures, or running demanding games or software while charging, as the heat generated will accelerate battery wear.

Avoid Continuously Full Charge: If you always use the computer plugged in, remember to enable the “Optimal Maintenance Mode” or “Balance Maintenance Mode” mentioned earlier to prevent the ASUS ZenBook S 13 Laptop Battery from remaining at 100% full.

Do you primarily use the computer plugged in, or do you frequently take it out with you? Tell me your usage habits, and I can help you determine the most suitable charging mode.

ASUS UX21 Zenbook Appearance and Design

ASUS UX21 Zenbook Appearance and Design

ASUS has gone to great lengths to create an Ultrabook that is very different from Apple’s Macbook Air.

The ASUS UX21’s casing is made of hardened aluminum, which looks and feels both durable and stylish.

Why does my ASUS Zenbook battery drain so quickly?

For example, running computationally intensive programs such as graphics software, gaming software, and video playback will accelerate battery consumption, and even some applications may continue to run in the background, taking up resources and shortening ASUS UX21 Zenbook Laptop Battery

life.

Keyboard and Trackpad

As for the trackpad, it should be quite satisfactory because it is made of glass. It looks quite large and comfortable, comparable to the trackpad of Apple’s Macbook Air.

Screen, Hardware, and Performance

The 11.6-inch screen equipped with ASUS’s new laptop looks quite good, at least in theory, with a resolution of up to 1366×768 pixels, bright colors, and excellent overall picture quality. As for the hardware, the UX21 is expected to be powered by a range of low-voltage second-generation Intel Core i3, i5, and i7 processors, similar to other upcoming Ultrabooks. It will also come with 4GB of RAM and will be available with a choice of 256GB or 128GB SSDs.ASUS UX21 Zenbook Laptop Battery Connectivity, and MoreThe ASUS UX21 will be equipped with a 6-cell battery and is expected to last up to 7 hours on a single charge. At least that’s what the Taiwanese manufacturer claims, because we’ve tried it many times before and it’s true.ASUS UX21 Zenbook Laptop Battery

Battery life should be around 6 hours. While it’s hard to say anything about a laptop that you haven’t tested and fully reviewed, what we can say right now is that the ASUS UX21 has a bright future and is expected to be a bestseller (emphasis on “maybe”).

The 11.6-inch ASUS Zenbook UX21 has an original and beautiful design, a solid and elegant build, decent performance, and only a few minor flaws. Therefore, it needs a suitable price to be popular and successful.

How to check the health status of a Samsung Galaxy A9 battery

The Samsung Galaxy A9 does not have an official function that directly displays the “Battery Health Percentage”. You cannot directly see a “Maximum Capacity” value similar to that on iPhones in the system settings. Checking the Samsung Galaxy A9 Phone Battery status of a Samsung Galaxy A9 phone primarily involves using official diagnostic tools to determine its overall condition, or viewing real-time parameters through engineering code.

Please note: Search results do not indicate that the Samsung Galaxy A9 (any model) supports directly displaying the specific percentage of remaining battery capacity. The following are feasible methods for your phone:

Method 1: Official Recommendation – Diagnostic via Samsung Members (Safest)

This is the only officially recognized software check method by Samsung, requiring no code or special permissions.

Install the app: Open Samsung Members on your phone (if you don’t have this app, please download it from the Samsung App Store).

Access Diagnostics: Tap the “Support” tab at the bottom → Select “Phone Diagnostics” (some versions may show “Repair” or “Test”) → Tap “Samsung Galaxy A9 Phone Battery Status”.

Result Interpretation:

This function does not display a specific percentage, but rather provides a comprehensive judgment of “Normal”, “Good”, or “Needs Check”.

If an anomaly is detected, the system will guide you to back up your data and go to a service center.

Suitable for: Users who don’t want to touch the codes and only need to know “whether the battery needs replacing”.

Method Two: Engineering Code – Viewing Real-Time Battery Parameters on Samsung Galaxy A9 Phones (Risk of Being Misleading)

This is a common hidden menu on older Samsung models (including early Galaxy A9s). It shows voltage and temperature, but not the remaining capacity percentage.

Operation: Open the dial pad and enter *#0228#.

Display: You will see real-time dynamic information such as current voltage, temperature, and battery status.

The Truth About “Samsung Galaxy A9 Phone Battery Calibration”

The *#0228# + Quick Start operation mentioned in forums can only calibrate the battery display and cannot restore lost battery capacity. If you feel the battery percentage fluctuates significantly, you can try this operation; if you simply feel “short battery life,” this operation is completely ineffective, and repeatedly performing it may actually increase the battery cycles of your Samsung Galaxy A9 phone.

Final Conclusion and Action Plan

If you simply want to confirm whether your Samsung Galaxy A9 battery needs replacing: Use Samsung Members diagnostics. If it’s “normal,” continue using it; if it’s “needs inspection,” go to a service center.

If you’re a tech enthusiast and want to see the data: You can use *#0228# to check the voltage and temperature, but do not believe the online rumor that “below 4.2V is unhealthy.”

If you feel the Samsung Galaxy A9 Phone Batterylife is significantly reduced: There is no software that can display “80% health.” Third-party apps (such as AccuBattery) estimate the capacity based on the Samsung Galaxy A9 battery’s charge/discharge cycles; this is for reference only and has a large margin of error, and cannot be used as a basis for replacement. The most accurate method is still to go to a Samsung service center for professional testing.

How can I check the battery status of my Pixel 4a?

Checking the “Google Pixel 4a Smartphone Battery Status” isn’t straightforward for your Pixel 4a, requiring an understanding of a key point: Google has permanently removed the built-in battery health indicator from the Pixel 4a, and a January 2025 update will artificially limit the battery capacity of some devices.

Here are three different methods for checking battery status, listed from most important to least important.

1. The Only Way to Determine if Battery Capacity is Artificially Limited (Highly Recommended)

This method doesn’t check the “health status,” but rather whether Google has intentionally reduced your battery capacity.

Official IMEI Lookup: Visit theGoogle Pixel 4a Smartphone Battery

Performance Plan page and enter your IMEI. This will tell you if your device is among the “Affected Devices.”

Importance: If your device is affected, regardless of its physical health, your battery capacity will be permanently reduced due to software reasons. Even a brand new replacement battery will have its capacity limited.

2. Removed “Battery Health” Feature (Unavailable)

In 2022, Android 13 QPR1 Beta introduced the “Battery Health” feature for the Pixel 4a, displaying an estimated capacity percentage (Settings > Google Pixel 4a Battery > Google Pixel 4a Smartphone Battery Health).

Actual situation: This feature was never officially released on the Pixel 4a. Google has removed the official system image. You cannot view the battery health percentage on the standard, latest version of the Pixel 4a.

3. General Troubleshooting (No Status Check)

Results from checking “Google Pixel 4a Battery Usage” (Settings > Battery > Battery Usage) or toggling the battery percentage only indicate battery consumption, not battery status or performance degradation. These results do not show the remaining battery capacity.

Note for Pixel 4a users:

Do not look for the “Maximum Capacity” percentage. This feature does not exist on your phone.

Please check if your device is among the “Affected Devices”. This will determine whether your recent short battery life is due to permanent damage or a software-imposed limitation.

If your device is affected, your only option is: a free Google Pixel 4a Smartphone Battery replacement (in select countries).

Samsung Galaxy Book 4 Pro 360 review

The Samsung Galaxy Book 4 Pro 360 is a thin, beautiful laptop that delivers performance and power efficiency. While it doesn’t play games very well and the power cord is a bit short, those willing to put up with those shortcomings will get an AMOLED-equipped 2-in-1 ultraportable laptop that can easily carry all day for work or school. I know this because I’ve reviewed multiple versions of this 16-inch 2-in-1 laptop over the years, and while I’ve always appreciated the Galaxy Book Pro 360’s ultraportable design and gorgeous AMOLED screen, I’ve been disappointed with the Galaxy Book Pro 360’s batterylife of recent versions.

Not so with the Samsung Galaxy Book 4 Pro 360. This is a proud return of one of Samsung’s best 2-in-1 laptops, and I think it delivers a perfect blend of performance, portability, and power efficiency that deserves our Editors’ Choice award.

The Galaxy Book Pro 360 series of 2-in-1s has always been at the top of Samsung’s laptops, and the latest version is better than ever thanks to the Galaxy Book Pro 360’s significantly improved battery life. Our Samsung Galaxy Book 4 Pro 360 review unit lasted for more than 12 hours in our Tom’s Guide

Samsung Galaxy Book 4 Pro 360 Battery

Test, which measures how long a laptop can continuously browse the web over Wi-Fi at low brightness settings.

Admittedly, 12 hours of Samsung Galaxy batterylife is lower than you’d expect from the best MacBooks, but it’s pretty good for a Windows laptop that doesn’t have Qualcomm’s new power-saving Snapdragon X chip on board.

Battery Life Test Results

It’s also much better than its predecessor, the Galaxy Book 3 Pro 360, which only lasted around 8 hours in the same Galaxy Book Pro 360 Battery

Test. That’s a bit frustrating, because the Galaxy Book Pro 360’s slim profile and focus on productivity make it ideal for a full day of work on the go, but on the older model you had to carry a charger with you if you thought you’d be out for more than 4-6 hours.

Not so with the new Samsung Galaxy Book 4 Pro 360. This laptop will easily get you through an eight-hour workday or a full day of classes, so you can leave the charger at home. Samsung GALAXY BOOK 4 PRO 360 Review: Conclusion

I really like this laptop, and I hope this Samsung Galaxy Book 4 Pro 360 review will show you why.

There aren’t many thin and light 16-inch Windows laptops with AMOLED touchscreens on the market for less than $2,000, so the Galaxy Book 4 Pro 360 not only achieves that goal, but also provides good Galaxy Book 4 Pro 360 battery life (12 hours as tested) and fast performance, which is a big deal. Samsung throws in a free stylus to go with this beautiful AMOLED touchscreen, which is simply the icing on the cake.

Sure, it was a little frustrating to have to consider the length of the power cord when I needed to charge on the go, but with such great Galaxy Book 4 Pro 360 battery  life, I rarely needed to bring a charger. While I couldn’t play my favorite games on this laptop, it’s not designed to compete with the best gaming laptops.

A week with the Surface Laptop 7: There’s a lot to like, but the Copilot Plus PC isn’t perfect

The first Microsoft Surface Laptop powered by Snapdragon X shows the potential of the move to Arm. Lingering emulation issues should make potential buyers think twice, but the performance boost, impressiveSurface Laptop 7 batterylife, and some interesting new AI features offer a sleek, refined Windows experience. I’ve been using the first Copilot Plus PC (Microsoft 7th Gen Surface Laptop) for over a week now, and the experience has been mixed. I’ve waited seven years for Windows on Arm to deliver on its promise of long battery life and performance that rivals the best in the industry. Thankfully, Qualcomm’s Snapdragon X platform delivers on these fronts, but there are still some caveats that should make potential buyers think twice before spending so much money.

On the other hand, we have AI, the current buzzword in the tech industry. While AI does offer some impressive capabilities, it’s on the verge of overuse and over-stuffing into every little feature of smartphones and now laptops. Add in competitive processing, and Microsoft is hoping AI can outdo Apple’s MacBook. But are Copilot Plus PCs the future of computing or just a flash in the pan?

If you’re considering buying one of these new machines, here’s everything you need to know about the experience.

For this review, I tested a 15-inch Microsoft Surface Laptop (2024) with a 12-core Snapdragon X Elite (X1E80100), 16GB of RAM, and a 512GB SSD configuration.

Microsoft Surface Laptop 7th Gen (2024)

Microsoft Surface Laptop

Copilot Plus PCs Meet Our Hardware Needs

Microsoft Surface 7th Gen USB C Ports

While I used a Microsoft Surface Laptop for this review, there are actually a lot of options if you want to experience the Copilot Plus PC experience. Dell, HP, Samsung, and others all offer hardware in the $1,300 price range with the same or similar Snapdragon X CPUs and dedicated Copilot keys. So, in terms of the core experience, these PCs are all very similar; the design, keyboard, and display features are very different.

Still, the Microsoft Surface Laptop’s design sets a new standard, and it’s well built, as you’d expect from a seventh-generation $999-plus laptop. The recycled aluminum alloy comes in a stylish Sapphire (blue) or Dune (bronze/tan) colorway, as well as practical black and silver. I opted for the latter and was not disappointed. With a pixel-dense 2,496 x 1,664 HDR touchscreen, responsive tactile keys, and future-proof Wi-Fi 7 support, Microsoft certainly showed us how good the Copilot Plus PC hardware is.

Surface Laptop 7 batterylife

My only complaint: The 15-inch model is a bit heavy at 1.7 kg (3.67 pounds), compared to the less-than-1 kg Huawei MateBook X Pro (2024) Ultrabook and the 1.24 kg MacBook Air. Still, Microsoft has packed in a battery that should easily get you through a full workday. As everyone has said, battery life on these devices is truly outstanding. I haven’t experienced Microsoft’s 20-hour video playback or 15-hour web browsing metrics (at a fairly dim 150 nits brightness), but the latter isn’t far off the 10 hours or more I’ve seen when using a laptop during the day. But there’s a big asterisk with these battery claims, which we’ll get to later.

No matter which Copilot Plus PC you choose, you’re getting Snapdragon X performance, AI extras, and longSurface Laptop 7 battery life.

For a cutting-edge device, I found the selection of USB ports a little odd. Two multifunction USB-C ports are flanked by USB-A sockets and a 3.5mm headphone jack, while a microSD card is hidden in another port, which I find useful. But it’s 2024, and I could live without the old port types if it made the laptop a little lighter (my desktop audio, display, and keyboard are on dongles anyway), but I appreciate that others might still find some use in these traditional use cases. Unfortunately, the USB-A port failed a few times for me, completely refusing to accept or power any connections until a reboot. Likewise, the USB-C port sometimes struggled to communicate with the DisplayPort through my USB-C hub. Maybe there’s something wrong with my device, or the hub isn’t very good. I haven’t had this issue with other laptops, though.

When you do eventually need to power the laptop, the 65W USB Power Delivery gets you back on pretty quickly, even if it’s not the highest power level you’ll see in a laptop of this class. Microsoft stubbornly sticks with its stupid proprietary connector port and bundles a 12-pin charger with the laptop (39W for the 13-inch model, 65W for the 15-inch). As far as I’m concerned, this plug is just e-waste, since I already power the laptop with one of the many USB-C plugs I already have.

A detailed explanation of the JBL Xtreme 1 (first generation) Bluetooth speaker battery.

As JBL’s early flagship portable Bluetooth speaker, the JBL Xtreme 1 Bluetooth Speaker Battery is a core part of its design, possessing both advantages and obvious limitations of its time.

Core Battery Specifications

JBL Xtreme 1 Bluetooth Speaker Battery Type: Built-in rechargeable lithium-ion battery

Nominal Capacity: 10,000mAh (This is a very large capacity)

Nominal Battery Life: Approximately 15 hours (Actual time depends on volume and playback content)

JBL Xtreme 1 Bluetooth Speaker Battery Charging Time: Approximately 3.5 hours (using the original 18W charger)

Special Features: Equipped with a 5V/2A USB-A output port, it can charge mobile phones and other devices, essentially functioning as a power bank.

Detailed Analysis and User Experience

1. JBL Xtreme 1 Bluetooth Speaker Battery Life Performance (Comparison of New and Old Conditions)

In its new condition: When playing pop music at medium volume (approximately 50%), it can indeed achieve nearly 15 hours of battery life. If the volume is turned up to maximum, the battery life will decrease to around 8-10 hours. 2. Charging Function

Reverse Charging: This is a highlight. Its built-in 10000mAh battery can fully charge an iPhone 12 (2815mAh) approximately 2-3 times. This feature is very useful outdoors.

3. JBL Xtreme 1 Bluetooth Speaker Battery Maintenance and Replacement

Maintenance: To prevent premature battery aging, if the speaker is not used for a long time, it is recommended to charge and discharge it every few months, keeping the charge level around 50%.

Replacement: Official: JBL does not typically offer battery replacement services, especially for such an older model.

Third-Party Repair: This is the most feasible solution. The battery is built-in but replaceable. You can search for “JBL Xtreme 1 battery” on e-commerce platforms (such as Taobao and eBay) to purchase a replacement JBL Xtreme 1 Bluetooth Speaker Battery manufactured by a third party.

If you are unfamiliar with electronic repair, it is recommended to have it handled by a professional mobile phone or speaker repair shop.

4. Common Problems and Troubleshooting

Flashing Red Light: A flashing red light during charging usually indicates a “charging error”. If the charger is working properly, the problem is likely a damaged battery or a faulty internal charging circuit.

Unable to power on or immediately shuts off: If the speaker fails to power on or immediately shuts off after being connected to the charger for a period of time, this is a typical sign that the battery is completely unusable.

JBL Xtreme 1 Bluetooth Speaker Battery

Severely shortened battery life: As mentioned above, this is the most common phenomenon of battery aging.

Summary and Recommendations

Advantages in retrospect: Back in its day, the combination of a 10000mAh battery and power bank functionality was the core selling point of the Xtreme 1, providing excellent JBL Xtreme 1 Bluetooth Speaker Batterylife and practicality.

Current situation assessment: For a device that is nearly ten years old, battery aging is inevitable and the most likely problem to encounter with the JBL Xtreme 1 Bluetooth speaker.
