Google today announced functional improvements for pixel 3, pixel 5 and pixel 4A / 4A 5g models, such as optimized battery life and adaptive sound, which automatically optimizes volume based on ambient noise levels. In addition, the hold for me call reserve function helps users cope with the waiting before connecting, introduces the extreme battery power saving mode, and the old devices will soon support the screen sharing function of Google duo calls. < / P > < p > in view of the increased battery life of the pixel 4 / 4 XL released last year, the new extreme power-saving mode seems to have gone too far. < / P > < p > but it is also useful for users of older devices (such as pixel 4 / 3A / 3) who occasionally need longer battery life or whose battery has begun to age. < / P > < p > in addition, adaptive charging can maintain long-term battery health. Google claims that it can dynamically control the charging rate of pixel devices at night, which is suitable for pixel 4 and later models. < / P > < p > in addition to improving GPS positioning accuracy, Google has also introduced intelligent 5g mode for pixel 5 and pixel 4A 5g models to improve the overall endurance performance. < / P > < p > by default, 4G can be used to complete simple tasks such as browsing, sending and receiving SMS, and intelligently switch to 5g network when you need to watch streaming media video. Unfortunately, not all apps and operators support this switching function. < / P > < p > in addition, the Google photo album app also provides pixel users with suggestions including dynamic enhancement of brightness, contrast and color rendering, or “one click to change the sky” to render wonderful images at sunrise / sunset. < / P > < p > adaptive audio features seem to be designed to improve pixel 5’s mediocre speaker output. The principle is to use the microphone to evaluate the ambient sound, and then adjust the equalizer settings adaptively in some apps. < / P > < p > for example, in the bedroom and bathroom, the adjustment parameters of the mobile phone to audio will be different. On privacy, Google claims that all locally stored microphone data recorded for speaker optimization will be deleted soon. < / P > < p > finally, Google enhanced the home screen customization experience of the pixel smartphone. As shown in the figure, the user can select a new icon, a grid view, and the shape of the app. < / P > < p > other minor improvements include the option to automatically recognize music being played by pixel and export it to YouTube music playlists.
