The rumoured OPPO A7 Pro Max is tipped to redefine battery life with a 10,000mAh battery with 80W fast charging. If true, it has the potential to provide multi-day battery life with relatively fast recharge times. The OPPO A7 Pro Max would be the company’s first smartphone with a 10,000mAh battery, made possible in a smartphone size by using silicon-carbon battery technology. The device is expected to target the mid-range smartphone segment and highlights the importance of battery life in mainstream markets. If launched with these specifications, the A7 Pro Max would position OPPO against other Chinese vendors that are rapidly increasing battery capacities beyond the traditional 5,000mAh to 6,000mAh range.
