In 2015, the domestic mobile phone industry ushered in unprecedented prosperity. It can be said that thousands of sails are in full swing, and old brands have made efforts, and newcomers are in full swing. At the same time, the fierce competition has brought the price and quality of mobile phones to a new height. Although the price system is facing a collapse, the form of mobile phone products has indeed improved. In addition to the metal body, fingerprint security has become a standard, the endurance of the pain that has plagued users for many years has finally reached a comprehensive leap this year, from 6000mAh + capacity battery to fast charge of the whole people, let us see the new hope of future mobile phone life . As a model that can represent the improvement of mobile phone technology in 2015, we will be the mobile phone project to be one of the theme of this year's horizontal review, and collect 17 typical models as test objects, to analyze the new trend of the mobile phone industry in the endurance level in 2015.
The generalized mobile phone battery life test is no longer limited to how long a mobile phone can be used for a long time. With the maturity of fast charging technology, how to provide us with faster charging efficiency is also included in the important part of mobile phone battery life performance. Therefore, we have selected the models from the two perspectives of fast charge and battery capacity, and judged the mobile phone's battery life in multiple dimensions.
2015 mobile phone battery cooling cross-evaluation model parameters list
There are many factors that affect the life of mobile phones, mainly in the four aspects of battery capacity, screen size, resolution, and processor. In addition to the monster-class 6020mAh battery capacity, we see that the mainstream battery capacity is concentrated in 3000-4000mAh, the resolution is concentrated in 1080P, and the screen size is mostly 5.5 inches. In order not to consider the mobile phone from the battery life factor, we also joined the price reference.
Mobile phone cross-test test standards and specifications
Charging test standard
1. Charging in the off state, all using the mobile phone's own charging plug to charge;
2. The charging link tests three times of charging for 10 minutes and charging to 60% and 100% of the time;
3. In view of the charging curve of the mobile phone, the initial efficiency of charging is the highest. We all test the output voltage and current in the initial stage of charging the mobile phone.
Discharge standard
4. During the discharge test, the mobile phone is set to enable Wi-Fi, the screen brightness is set to environment automatic, and the external sound is adjusted to medium, except that the call test items are not inserted;
5, discharge test in accordance with the sequence test music playback (30 minutes), video playback (45 points total), mobile games (45 minutes), calls (15 minutes), e-book reading (30 minutes), microblogging (15 minutes) ) Tested in six sessions, the test time is 3 hours.
6, six tests use the same test tools: music playback (Netease cloud music), video playback (a set of American drama), mobile games (wild car 8), e-book reading (read iReader, set automatic page turning mode).
Note: All the links simulate the daily use of the user, and try to restore the usage habits of most users to obtain the true battery life data. The three-hour simulation is a heavy test. Some tests (such as 45 minutes of game play and CPU limit) are mainly prepared for the heat-dissipation link. Users cannot strictly follow this data.
Charging test link: fast charging technology eye-catching
The two aspects of determining the charging speed are battery capacity and charging power. From the summary data, it can be seen that the current mainstream mobile phone power is mainly concentrated between 3000mAh-4000mAh, but the iPhone 6s Plus uses a 2750mAh capacity battery for the system. Optimization is quite confident.
At the same time, fast charging has become the standard for mobile phones in 2015. Especially after the fast charging technology such as Qualcomm's quick charge 3.0 continues to improve, more and more mobile phones will quickly become one of the mobile phone selling points. In this charging test, we also focus on testing whether the mobile phone has a fast charging function, and the actual fast charging effect will be reflected in the test.
Fast charging technology eye-catching
On the test session, we set three data points of 10 minutes, 60% and 100% respectively:
10 minutes to test the fast charge capacity of the mobile phone, how much power the mobile phone brings to us when the test time is tight;
60% power, this is the comfort threshold of the user's mobile phone battery demand, when we do not need to fully charge 60% is a psychological balance zone, charging to 60% of the time required to set one of the links.
100% power, how long it takes from zero to full power.
