Hello, the nominal battery time refers to the test standby time. The specific use time of the notebook is related to the running environment of your system. The standby time of notebook when running large programs, software or using CD-ROM drive will be shorter than that only used for word processing. In the case of a certain battery capacity, the battery life will be shortened to normal. Usually, only documents are edited, and the battery life of web browsing is about 50%~60% of the nominal standby time.
Notebook batteries are consumables, and with the increase of charging times, the power will continue to decrease. After general charging 100 times, the power is reduced to 90% of the original. Due to different usage habits, the battery service time will be different. When the battery life is coming to an end, the battery will not be able to charge and discharge normally, reminding you that you need to replace the battery.
