Battery life showdown! Unveiling the truth about the battery life of wireless audio guide devices

Unlike ordinary consumer electronics, the battery life of wireless audio guide devices is not simply determined by the higher the number, it is crucial to be stable, durable, and adaptable to various scenarios. Especially for customers, who often need to lead tours outdoors for long periods and handle multiple batches of visitors consecutively. Yingmi has been in this industry for 18 years, starting from 2007 until now, and has always prioritized battery life optimization as a core matter. Coupled with overseas export experience, the products have been sold to dozens of countries such as Spain, Hungary, and the United Arab Emirates, and have long understood the pain points of customers and developed several wireless audio guide devices with particularly strong battery life.

What customers must know: The 4 pitfalls of wireless audio guide devices' battery life, avoid them at all costs

Many customers choose wireless audio guide devices and tend to fall into a common misconception: they think the higher the battery life value indicated, the better the device. But when they actually use it, they find that many products labeled with "20-hour battery life" actually can't even last 10 hours, especially in outdoor hot and noisy environments, the battery life drops rapidly. Combining years of experience serving customers, I have summarized the four most common battery life pain points, which are also the areas that everyone should avoid when making a purchase.

Pain point one: Severe battery life misrepresentation, the difference between publicity and actual testing is half

This is the most frequently reported and most troublesome problem by customers. Some small manufacturers, in order to sell their products, deliberately exaggerate the battery life, marking "full battery life of 24 hours", but when actually used, because they use inferior batteries and have poor energy consumption control, under continuous playback of narration words, they can only last up to 8-10 hours at most, which simply cannot meet the needs of a full-day tour or exhibition reception. Especially for tour guides, when the equipment runs out of power halfway during the tour, the narration rhythm is disrupted, the tourists' experience is bad, and complaints are likely to arise, it is really a big problem.

Pain point two: Battery life drops faster in outdoor/noisy environments

Customers use audio guide devices mostly in scenic spots, castles, factories, etc., and in outdoor or noisy environments, high temperatures, direct sunlight, and strong interference will make the device consume power faster. Many audio guide devices perform well in indoor tests, but when taken to an environment of 30°C or above outdoors, the battery life drops by 30%-50%, and it may even freeze or suddenly lose power. What's worse, in noisy environments, tourists need to turn up the volume to hear clearly, which makes the battery consumption even faster. The already insufficient battery life is even more strained.

Pain point three: Low charging efficiency for batch charging, affecting the next day's itinerary

In exhibition halls and travel agencies, there is usually a need for batch use of wireless audio guide devices, from dozens to hundreds. If the charging efficiency is low, it takes several hours or even an entire night to charge once, and the next day's reception and tour itinerary will definitely be affected. What's more troublesome is that some products do not support wide voltage, and the voltages in various countries overseas are different, such as 230V in Europe and 120V in America. Extra transformers need to be bought, which is both costly and troublesome, and it may even affect the charging efficiency and shorten the battery life.

Pain point four: Unreliable battery life, battery life drops sharply after a period of use

Wireless audio guide devices are high-frequency use devices, customers use them almost every day. If the battery quality is poor, after using for half a year to one year, the battery life will drop significantly, from 12 hours to 5-6 hours, and frequent charging or even battery replacement will be necessary. In the long run, the cost is not low. What's worse, some manufacturers do not provide battery replacement services, and when the battery is broken, the equipment can only be replaced as a whole, which is undoubtedly an additional blow.

Yingmi's personal test: Two products, solving all battery life problems

In response to these battery life pain points of customers, Yingmi, relying on 18 years of technical accumulation and overseas experience, has developed several high-battery-life wireless audio guide devices. Among them, the M7 neck-mounted automatic sensing guide machine and the E8 wireless audio guide device, have stable battery life, convenient charging, and are particularly suitable for various overseas scenarios, becoming the preferred choice of customers. Based on the actual measured data, let's elaborate on the battery life advantages of these two products to help customers make an informed choice according to their specific scenarios.

Scenario 1: Self-guided tours - M7, no need for charging throughout the day

For self-guided tours in scenic spots and museums, tourists use the equipment from opening to closing, a total of 8-10 hours. The requirement for battery life is simple: long-lasting and stable, without frequent charging. The Yingmi M7 neck-mounted automatic sensor guided tour device is specifically optimized for this scenario. After actual measurement, the full charge battery life can reach over 16 hours, fully covering the daily usage needs, without the need for charging interruptions.

Let's talk about the actual measurement data, which will give you a better understanding: M7 is equipped with an 800mAh high-performance polymer lithium battery, and uses Yingmi's own developed PMU safe intelligent power management technology, which can effectively save power and avoid waste. In a normal temperature environment, continuous playback of the explanation (volume set to 50%, similar to daily use) can last for 16 hours and 40 minutes; even in an outdoor 35°C high-temperature environment, the battery life can reach over 13 hours, with a degradation rate controlled within 20%, much better than the industry average. Additionally, M7 has an automatic sleep function. When tourists leave the guided point, the device will automatically enter sleep mode, further saving power and ensuring longer battery life.

Charging is also very convenient. M7 is equipped with a dedicated wired charging box, which can charge 32 devices at the same time. It adopts a trickle charging - constant current - constant voltage charging mode, which not only charges quickly but also protects the battery and extends its lifespan. After measuring the charging of 32 devices simultaneously, it only takes 4 hours to fully charge all of them, without delaying the opening of the exhibition hall or the reception of the scenic area the next day. The most important thing is that the charging box supports a wide voltage range of 100V-240V, allowing it to be directly plugged in anywhere in the world without the need for additional transformers, saving customers a lot of trouble.

Scenario 2: Team guided tours - E8, continuous power supply for the entire tour

For guided tours by tour guides and enterprise receptions, it belongs to the team guided tour scenario. Tour guides and tourists need to use the guided device for a long time, sometimes even for outdoor and long-distance explanations. The requirement for battery life is: long-lasting and resistant to attenuation, and convenient for charging. The Yingmi E8 wireless guided device is a classic ear-mounted team guided device. After actual measurement, the full charge battery life can also reach over 16 hours. It perfectly meets the needs of team guided tours throughout the day.

E8 is a one-piece design, very lightweight, weighing only 16 grams. Tour guides have no burden when carrying the transmitter, and tourists do not feel pressure when wearing the headphones. It is equipped with a high-performance lithium battery, combined with the embedded SOC integrated digital noise reduction technology, which can ensure clear sound quality while reducing energy consumption, achieving both sound quality and battery life. After measurement, when the E8 is fully charged, the tour guide can continuously explain (transmitter) and the tourists can continuously listen (receiver), and it can last for over 16 hours. Starting from 9 a.m. for the tour and closing at 7 p.m., the device still has about 25% of battery left, even if there is an additional explanation, there is no need to worry about power loss. In an outdoor noisy environment, when the tourists increase the volume, the battery life can also reach over 12 hours, with a degradation rate controlled within 25%, fully meeting the needs of long-term guided tours.

Charging, E8 is equipped with a contact-type charging box, which can charge 36-48 devices at once. It charges very quickly and after measurement, it only takes 5 hours to fully charge 48 devices, which is particularly suitable for travel agencies and enterprises for batch management. Moreover, this charging box also has a UV disinfection function, which can disinfect the devices while charging at night, making management convenient and ensuring the hygiene of tourists' use, especially meeting the requirements for hygiene and safety in overseas markets. Additionally, E8 also supports a wide voltage range of 100V-240V, allowing it to be directly used in any country in the world without the need for additional accessories, making it more convenient to use.
