How to Solve Smart Watches Battery Life

Gartner, the world's leading information technology research and consulting firm, predicts that global wearable device shipments will reach 225 million units in 2019, an increase of 25.8% from 2018. In 2019, global end-user spending on wearable devices is expected to reach $42 billion, among which smart watches occupies 16.2 billion US dollor.


A smart watch is a networked platform that interacts with smartphones and various other networked devices to perform tasks such as reviewing text messages and emails, playing streaming music, and screening incoming calls. It's a new product category that revolutionizes the use of wearable technology. In the meanwhile, it continues to introduce innovative usage models.


Smart watches were once seen as a replacement for smartphones, but they did not develop to their own era. Although lithium batteries have smaller, lighter volume and higher energy density than earlier nickel batteries, the root cause of poor performance of smart watches is mainly limited by the current battery technology that is without a breakthrough.

However, in a limited volume, from a safety point of view, smart watches can only use lithium batteries of about 300-400 mAh, and the endurance that it can provide is limited by the consumption of screens and high-performance processors.


According to the research organization IDC’s market data for smart watches, the shipments of smart watches in Q3,2018 decreased by 51.6% compared with the same period of last year. Tracing back to this market performance, the poor battery lift of smart watches affects the consumer experience is as one of the most important reasons.


In order to improve the battery life of smart watches, many manufacturers choose to act unwisely towords smart watches, just like the popular crowdfunding Pebble, which uses the electronic ink screen design to give itself a relatively long battery life. Although it can also support Android and iOS systems, the system expansion and platform development capabilities of the entire smart watch are far less than Apple Watch OS and Google Wear OS. Frankly speaking, such a smart watch is a fake smart watch product, which is more like a smart bracelet with the appearance of a traditional watch.


The problem of battery life and the reality of the large number of manufacturers bringing pseudo-smart watches to enter the market have also led many consumers interested in smart watches to purchase smart bracelets with higher cost performance. Although the smart bracelet does not have the problem of battery life,   it is not being smart enough is hard to take on the role of the mobile phone era. How to find a balance between function and battery life will become the thinking direction of smart watch manufacturers in the future.


Until now, large manufacturers such as Apple and Huawei still struggled to optimize system power consumption. Although they have achieved certain results, they still cannot solve the problem of the battery life of smart watches. Under the normal use condition, Apple Watch Series 3 can only maintain just a day while Huawei Watch 2 Pro is nearly a day and this performance is still not satisfied with consumers.


Is there a better solution? At present, manufacturers such as Huawei and Apple have not given a better solution that can balance both life and intelligence. It is worth noting that Grepow has launched a smart watches battery with a "revolutionary" upgrade in battery life, with a smaller size, higher energy density, and custom shape battery.
