In airplane mode, playing local 1080P videos at 50% brightness and volume, the battery life approached or reached 7 hours, which is quite close to the official claim.
Intensive Use or Using the E-Ink Display:
If you perform more complex tasks or frequently use the main screen at high brightness, the Lenovo Yoga Book C930 Laptop Battery life will be further reduced to 4-5 hours.
A key feature is that when using the device as an e-book reader or notepad (using only the E-Ink display, with the main LCD screen turned off), the battery life is greatly extended, easily exceeding 10 hours, a significant advantage over traditional laptops.
Charging Speed: The Yoga Book C930 supports fast charging.
Officially, it charges to 80% in one hour. In actual experience, theLenovo Yoga Book C930 Laptop Battery

Official battery life is the same: Wi-Fi: up to 15 hours; video playback: up to 18 hours. This applies to both the 13-inch and 15-inch M2 and M4 models. MacBook Air M4 Battery Capacity: Both models use lithium-polymer batteries of essentially the same capacity. Apple doesn’t provide specific figures, but teardowns and testing indicate that the M4 model doesn’t increase the physical capacity of the battery.

Charging Specifications: Both models support MagSafe or USB-C charging. The base 13-inch model ships with a 30W or 35W charger. Both models support an optional 70W USB-C fast charger, charging to 50% in 30 minutes.

iPhone 15 Pro review: Entering the USB-C era

This year, Apple made a number of significant changes to the iPhone 15 Pro: a switch to titanium for a significantly lighter phone; some welcome camera improvements that will elevate your photography; and the world’s first 3nm chip, along with a number of smaller enhancements. Despite all the tweaks and changes,iPhone 15 Pro Smartphone BatteryLife, the one area everyone hoped for improvement, well…it hasn’t improved much, if at all. Also, a word of caution: If you’re looking for that cool new 5x zoom lens on the smaller iPhone 15 Pro…well, it’s not here! That lens is only available on the larger Pro Max model, which you can learn more about in our iPhone 15 Pro Max review.iPhone 15 Pro Smartphone BatterySame LifeThe iPhone 15 Pro has the same 6.1-inch screen as its predecessor, but the bezels are a third thinner. While subtle, this change contributes to a more modern, sleek, edge-to-edge look.
The screen technology hasn’t changed much: OLED, Retina, and with 120Hz ProMotion support for a smooth scrolling experience. Of course, the previous model’s Always-On feature remains. The iPhone 15 Pro features the familiar triple-rear camera system, consisting of a main 1X shooter, an ultra-wide-angle camera, and a 3X telephoto lens with a 3,274 mAh battery.iPhone 15 Pro Smartphone BatteryThis is slightly larger than the previous model (+2.3%).
However, the actual battery life of the iPhone 15 Pro is the same as the previous model, at least according to Apple’s official figures.iPhone 15 Pro Smartphone BatteryBased on the lifespan data, the 15 Pro’s battery life should be similar to the 14 Pro, but with more frequent use, the new 15 Pro may last slightly less than the previous generation. Other changes, such as the new USB-C port and the new “action” button, make the user experience more convenient.
All in all, the iPhone 15 Pro is a decent upgrade, but it has some very specific features that you may or may not care about, and it doesn’t change the one thing most people care about:iPhone 15 Pro Smartphone Batterylife.

Test: Vacuuming and mopping robot with base Dreame X40 is the “king” of the edge

Smart mop, retractable side brush and hair trimmer – the Dreame X40 Ultra Complete is coming soon and it has these features and more. This test shows its strengths. Test conclusion

In the battle for the best vacuum mopping robot, Dreame keeps catching up and has taken the throne with the X40, tied with the Roborock S8 Pro Ultra. Where competitors still navigate and navigate a little better, Dreame is the king of cleaning edges and corners. Not only can the right wiper fold up to the edge, the rotating side brush can also be extended. This means that the robot in the test removed almost all the peas in the corners – and a lot of dirt in everyday cleaning. Now standard in this price range: a multifunctional base for vacuuming, oiling, rinsing and hot air drying. Very good suction and mopping performance

All brands laptop battery in here, We sell cheap and high quality laptop batteries , Tablets battery, mobile phone battery, you choose.
Good cleaning in corners and edgesMultifunctional base Dreame takes off in Germany. At the product launch in Hamburg, the manufacturer proudly announced that it has now secured the largest market share for vacuum mopping robots in the country, ahead of Roborock and Ecovacs. It can be said that Dreame cleaning tools like the L10s Ultra are real bestsellers. Following the mid-range model in the “Heat” edition, the Chinese supplier is now sending a new top model to the race. This test reveals the performance of the Dreame X40 Ultra Complete.

Dreame X40: A real actuaryIn recent years, Dreame has become a real innovation driver. It was the first on the market to offer a rotating wiper and hot air drying. Now Dreame has made the rotating side brush even smarter: When the X40 cleans corners, it folds an arm at the front right so that the rotating bristles can clean up the last crumbs. This works very well in the test: out of 20 peas in the corner, the robot was able to eat an impressive 17. This is a record! Other vacuum cleaners without folding arms usually only collect half of the vegetables.

Detecting dirt: Constantly movingPractical: Dreame adjusts the concentrated cleaning power to the different surfaces – the X40 is more powerful on deep-pile carpets and more conservative on smooth surfaces. The robot cleans more carefully in automatic mode. With Clean Genius, the software and sensors decide for themselves which floor to clean and how. The X40 removes everyday dirt quickly and effectively, and cleans more thoroughly when the dirt is heavy. If the first attempt doesn’t work, the Dirty Detective will first order a cleaning at the dock, followed by a second or third round of cleaning until everything is spotless.

How AI is revolutionizing battery storage for a greener future

Battery energy storage is essential to improving the reliability of renewable energy. It can collect extra energy from solar and wind power to provide electricity when needed. However, artificial intelligence (AI) is taking battery management to the next level.

Experts say AI software is now key to managing large battery systems. Companies are applying AI not only to basic tasks but also to energy trading, safety monitoring and predictive maintenance.

Advanced AI technologies enhance battery energy storage

Battery systems use intelligent tools such as machine learning, deep learning, predictive analytics and reinforcement learning. They are becoming a key tool for managing large battery systems.

Batteries store and release energy efficiently based on demand.

Optimize performance by processing real-time data to reduce waste and improve efficiency.

These upgrades provide a stable and reliable power source, making battery energy storage more viable and cost-effective.

S&P Global says the market demand for battery energy storage systems is growing. However, the integration of  AI  is just getting started. Lithium-ion battery energy storage developers are well positioned to meet this demand.

Henrique Ribeiro, lead analyst for batteries and energy storage at S&P Global Commodity Insights, said:

“As market competition intensifies and more capacity is deployed, maximizing returns may become increasingly difficult. Therefore, such tools may become an advantage.”

Improving battery energy storage safety

Scientists, researchers and experts agree that manufacturing high-quality batteries is technically complex and challenging. As lithium-ion battery production grows, especially in China and the United States,  AI analysis will become increasingly important.

A major challenge is the rapid pace of innovation. If manufacturing errors go unnoticed, they can cause serious problems. Thermal runaway is one of them, which can cause dangerous fires. However, AI can help detect problems early and avoid costly failures.

Like other energy storage systems, batteries also have safety risks. This is a cause for concern. However, this challenge also provides an opportunity for the industry to improve safety measures.

Organizations such as the Industrial Electrotechnical Committee (IEC) and UL Solutions are raising safety standards. Therefore, effectively managing these risks is essential to maintain industry momentum.

As energy storage technology develops,  AI will help optimize operations and ensure grid reliability and sustainability.

Anker SoundCore Flare 2 Bluetooth Speaker Battery Review

Anker SoundCore Flare 2 Speaker BatteryCapacity: The Flare 2 is officially rated for up to 12 hours of playback at moderate volume.

Actual Performance: Most users find this estimate to be fairly accurate when the speaker is new. You can expect 10-12 hours of battery life at around 50% volume (without the extra bass mode enabled). At high volume (above 70%) (with the LED base light on and the extra bass mode engaged), you’ll get 6-8 hours.

Anker SoundCore Flare 2 Speaker BatteryCharging: It charges using USB-C, a welcome modern upgrade at launch. A full charge typically takes 3-4 hours.

Long-LastingAnker SoundCore Flare 2 Speaker BatteryLife: For its size and price, the 12-hour battery life is very competitive and more than enough to last you through a day at the beach, the park, or even a full workday. Reliable Brand Reputation: Anker uses high-quality lithium-ion batteries. Under normal use, premature battery failure or swelling in the Flare 2’s first few years is uncommon. Consistent Power Delivery: The battery provides continuous power, ensuring the speaker maintains its sound quality until the battery reaches critically low levels.

Inevitable Performance Degradation: After 2-3 years of normal use and charging cycles, you will notice a decrease in play time. This is normal for all lithium-ion batteries, but the non-replaceable nature means that it effectively determines the speaker’s “lifespan.

Complicated Replacement Process: If the battery fails, replacing the Anker SoundCore Flare 2 Speaker Battery is difficult and invasive, and risks damaging the speaker.

Long-Term Reviews and Common Problems

The most common complaint over time is decreased battery life. Years of experience with the speaker have reported that a battery that once lasted 12 hours may only last 4-6 hours on a full charge.

Final Verdict

For new speakers:

The Anker SoundCore Flare 2 speaker’s battery is a real plus, delivering reliable all-day playtime. For speakers over two years old: Expect significantly shorterAnker SoundCore Flare 2 Speaker Batteryife.
