For added context, the Galaxy S20+ has a rated battery capacity of 4,370mAh, which translates to a typical capacity of 4,500mAh. Assuming Samsung manages to maintain its production efficiency, this should once again result in a roughly 3% increase in typical capacity, or 4,800mAh.
The rest of the Galaxy S21 series likely to follow suit
Samsung achieved a similar capacity increase this year, as well, with the Galaxy S20+ offering a 400mAh improvement in both rated and typical capacity over the Galaxy S10+ (4,000/4,100mAh). Naturally, it's unlikely the middle model will be the only one to offer such an upgrade, not to mention that a higher capacity doesn't guarantee longer battery life, especially as smartphones are still getting bigger every year.
The next generation of Samsung's Galaxy S smartphones is expected to launch early next year, most likely in February, as is customary for the company's mainline flagships. More details on the devices are bound to follow shortly as the Galaxy S21 range is presumably only a couple of months ahead of its first prototype production run.
