Of course, the larger the number of cores, the longer the battery life, and of course the higher the price, but the stability will be less than the battery core. Ordinary home users recommend using the number of cores that are standard with their computer, such as 3 cores and 4 cores, because they are mainly used at home and have a stable power supply. Ordinary office users recommend using 6-cell and 8-cell batteries, because the standby time is relatively long, which makes your office more convenient. If you have high mobile office requirements, you can consider 9-cell and 12-cell batteries. These batteries are too heavy to carry, and they are not as stable as 6-cell and 8-cell.
