First of all, it has a large battery of 5000mAh. Compared with fast charging, it is more suitable for the elderly to stand by for a long time. After all, they are not as good as us young people in the long run. What they want is to go for a walk and come back with a full battery. The low-power cat 700 chip is equipped with a large battery, so the battery life is not worrying.
Then the ColorOS 1 1 system of OPPO A56 also has memory expansion, and it has been escorted smoothly for 36 months. Smoothness is also more reliable. In addition, the system has a simple mode. In fact, what I value more is its remote guardian function, that is, I can operate her mobile phone remotely, and I can help her solve it if I can't find the payment code or health code, which is very user-friendly.
