Is it proven that continuous operation on the power supply unit is harmful to the battery?
With a manufacturer like Huawei, it would be conceivable that the battery is no longer loaded or charged when it is full. Or perhaps there is even a trickle charge.

Accepted Answer

My Huawei E5885 has mainly been connected to the mains for a year. When it is not (i.e. power failure or on the move), the battery lasts about 1 day. I can also confirm that the network quality has an influence on the battery consumption. I have 2 providers (device is not dual-sim). The battery runs out faster with Sunrise/Yallo/Digitec IoT than with Swisscom/M-Budget/Wingo. For operation with Huawei E5885, I recommend the current cheapest Wingo offer. With the Swisscom network, you are much better off in the sticks. I would also like to mention that the data offers on the Sunrise network are useless. The flat rate is true. But nobody writes that the bandwidth is massively throttled after about 1Gb. After the Gb, you will be faster at peak times with a 56k modem.
The Huawei E5885 is certainly one of the best mobile WiFis available with a LAN port.

Answer

I can't prove this, but I have two Huawei E5885LS-93As and one of them is always connected to the network. In a mobile comparison, the modem that I always carry with me and only charge from time to time lasts a little longer (about 15 minutes) than the one that is always connected to the network. It also depends on whether you always have good or poor reception. As I see it, the reception and transmission power is increased when reception is poor, which would also affect the battery power. But since you can change the battery in the modems, this is not so important for me. The standby mode is also pleasant, which means that the charging cycles last considerably longer.
I have 3 of these devices. One has been in continuous operation for 3 years. It has lasted longer than a Netgear. The Netgear started to go haywire after 2 years (after the warranty period had expired) and would suddenly reboot every now and then in wifi mode. This has only happened once with this device, and only when I had more than 15 devices connected to it.
I hope this helps a little.
