Currently, the 4G180/4G185 latest hardware version is with 2100 mAh battery. However, the actual battery time may vary due to different user environments, so some customers might feel that the battery drains quite fast and even think the battery is defective. Actually, the battery life is affected by the power consumption, larger power consumption, and shorter battery life. The power consumption will increase in the following conditions:

1) Poor LTE signal

Please check the network type and signal strength, if the signal is quite weak, please try to move it to somewhere else with a good 4G signal.

2)Too many clients are using the internet at the same time or some clients are using high-traffic operations such as large file downloading, streaming or gaming, etc.

Try to disconnect some client devices, and test again when client devices are only browsing the internet normally.
