Remarks 1, RAM + memory expansion technology is through software means, the background cache application compression to the mobile phone storage, in order to increase the number of background cache application and release more operating memory space, improve system smoothness, rather than hardware level expansion of operating memory. 2, OPPO A2m using a single-cell battery, the battery rated capacity of 4890mAh, the current test has completed 1200 cycles, the life of the maintenance is still more than 87%, based on the past models of platform samples limit validation, the probability of the daily cycle of the projected, the mobile phone using the battery after four years of cycling is still more than 80% of the battery capacity retention rate. 3, 300% super volume comparison for 100% volume of the same model products. 4. Diamond drop-resistant structure means that the product meets the quality standards of OPPO's own factory through a number of optimisations. There is still a risk of damage if the phone is dropped or bumped. Please pay attention to avoid dropping and collision in daily use. Airbag refers to cushioning materials such as foam and silicone pads. 6, OPPO A2m is splash-proof, water-proof and dust-proof under normal use. Under controlled laboratory conditions, it has been tested and its effect is up to IP54 level under GB/T 4208-2017 (domestic) standard. Splash-proof and dust-proof functions may be degraded due to wear and tear from daily use. IPX4 waterproof conditions: ① water spray volume: 1.8L/min ② test time: 10min ③: water spray pendulum speed: 60°/s. IP5X dustproof condition is: ① Imitation dust box blowing dust 480min. Please do not charge the mobile phone in a wet state. There is a difference between the living scenario and the experimental environment, so please do not completely immerse the mobile phone in water for daily use, or contact it with seawater, chlorinated water and other solutions, or in liquids such as beverages. Damage caused by immersion in liquids is not covered by the warranty. 7, data based on OPPO laboratory calculations, to the photo about 3M / Zhang calculation; the above data is for reference only, due to different shooting modes, the actual number of storage may vary. 8, 48 months of smooth navigation means that through software, hardware and other comprehensive technical optimisation, the OPPO A2m has passed the 48-month anti-aging test under the professional testing environment of OPPO Labs. Smooth navigation is not the same as absolutely no lag, due to the network environment, personal habits and other factors, the actual experience may vary. Only the version with 8GB of RAM and above supports 48 months of smooth navigation. 9, OPPO A2m's global default maximum brightness is 580 nits (typical), the global inspired maximum brightness is 720 nits (typical). 10、Volume data are provided by official labs or suppliers, please refer to actual experience. 11、Some health indexes rely on IoT product interconnection and synchronisation data. 12. Data from LUGU's official platform, ColorOS was awarded the smoothest system by LUGU from 2020 to 2022. 13, data from the official platform of LUGU, ColorOS won the first half of 2023 LUGU smoothest system. *Four-year durability means that the OPPO A2m meets the criteria of four-year battery durability and four-year system smoothness in official tests. The actual experience may vary depending on the actual usage and habits of the individual. *Unless otherwise noted, the data shown in the above pages are OPPO lab data and are for reference only. Actual data will vary slightly due to the use of the environment, device conditions, software version and other factors, please refer to the actual data. *If no special note, the product interface content (including but not limited to UI, background) shown in the above page is only for functional display, each function belongs to a different software version, different software version of the on-line time and the region varies, please refer to the actual version of the function and interface shall prevail. *Please refer to the actual version of the functionality and interface. Some product specifications and descriptions may be changed due to the change of suppliers, please refer to the actual product. The data herein are from OPPO design technical parameters, laboratory and supplier test data, the actual situation may vary slightly depending on the version of the test software, the specific test environment, the specific version.
