I Bought Acer Laptop SFX14-41G Just Replace new battery. How long New battery Last with 100% Charge?

Theoretically, if it lasts 2 hours and 33 minutes when starting at 56% charge, it should last about 5 hours with a 100% charge. What you are doing during that time though will be a greater effect than anything else.

There are so many different parameters that affect battery life that there is no good answer to that question. Usually screen brightness is the largest factor when not taxing the CPU and GPU, though network activity can also play a large role.

The Acer Swift X SFX14-41G, with its 59Wh battery, can last up to 17 hours on a full charge according to Acer. However, actual battery life can vary depending on usage, such as screen brightness, running applications, and network activity. For typical usage, you might expect around 5 to 10 hours. If you have specific usage patterns, the battery life might differ.

Also, this model is designed to handle frequent charging without significant degradation. However, it's a good practice to avoid keeping the battery at 100% for extended periods. Instead, try to keep the battery level between 20% and 80% for optimal longevity. Charging it when it drops below 70% is generally recommended.
