Battery Life and Charging
The Samsung Galaxy Z Fold 4 5G, featuring a robust 4,400 mAh battery, is designed to cater to users who demand extensive performance from their devices. In real-world usage scenarios, users have reported that the phone can easily last a full day with regular tasks such as browsing, streaming videos, and multitasking between apps. Those who utilize the device more intensely, particularly for gaming or using high-performance applications, may need to recharge by evening. However, the relatively large battery capacity provides a commendable base for daily use, considering the phone’s foldable design and advanced features.
Charging speeds are another critical aspect of the Galaxy Z Fold 4’s appeal. The device supports fast charging at 25W, which means that users can recharge the battery significantly in a short period.
