During the rehearsal of this year's CCTV Spring Festival Gala, several hosts used AI assistants on their mobile phones in the background to pay New Year's greetings to audiences across the country, making many people aware of "AI phones" for the first time. AI phones do not require the use of third-party apps, but instead become the user's personal secretary through the phone's own computing power. Some institutions predict that the shipment volume of new generation AI smartphones in the Chinese market will reach 37 million units in 2024, and 150 million units in 2027, with the new generation AI smartphones accounting for over 50% of the market share. From feature phones to smartphones, and then to the latest AI phones, what new, more intelligent, and personalized user experiences can it bring to people? The shift from smartphones to AI smartphones has become a trend in 2023. Generative AI continues to emerge, greatly improving people's work efficiency and even having a significant impact on some industry changes. Both domestic and foreign technology giants are developing and building their own big models. In January of this year, Samsung's first AI phone attracted attention. Apple also has news that the next generation of iPhone phones will be equipped with generative AI. Nowadays, the shift from smartphones to AI phones has become a trend. Domestic mobile phone manufacturers are testing the waters one after another, including Huawei, Honor, Xiaomi, OPPO, and vivo, all of which have successfully deployed large models on the mobile end. Recently, Meizu suddenly announced a strategic adjustment - to transform All in AI, stop traditional "smartphone" new projects, and move towards the AI field. OPPO founder Chen Mingyong also released an internal letter stating that 2024 is the first year of AI smartphones. In the next five years, the impact of AI on the mobile phone industry can be comparable to that of smartphones replacing feature phones. From the perspective of industry development stage, AI smartphones will also become the third stage of the mobile phone industry after feature phones and smartphones. What can the "cloud collaboration" AI phone be transformed into a personal secretary AI phone? From the evaluation of AI smartphones that have been released so far, it can be seen that in addition to the common document organizing ability of generative AI, AI phones can also perform convenient image processing, such as "one click removal" of passersby, cluttered backgrounds, mirror reflections, etc. in photos, except for the main characters. Moreover, the effect calculated by AI may be more natural than that processed by professional image processing software with more effort. How is this different from using third-party software for image and text processing? In fact, the biggest change in AI phones is that they are processed through their own computing power. Previously, in order to implement these functions, it was necessary to transmit them to the cloud through third-party apps, which would have a certain impact on processing speed and instant response speed. But AI phones have achieved "end-to-end cloud collaboration", which means that some complex tasks that require a lot of computation are transmitted to the cloud for processing, and some simple daily tasks are directly processed using the large model on the phone, greatly improving work efficiency. For example, existing AI phones can achieve real-time call translation and call summary functions, which have practical usage scenarios. For example, when making voice calls with people using different languages, the mobile phone can convert voice and text in real-time, enabling smooth communication between both parties; And users can receive important calls but not
