Nighthawk M1 battery flat and offline in morning
Hello, I have a Telstra Nighthawk M1, works pretty well. Happy with the speeds, the form factor, real ethernet port and on the very infrequent times I use it without power the battery life. ...
If you believe the power adapter is not capable of charging the device, then try switching off one of the two WIFI modes on the router. This way the power consumption will drop and the power adapter will be enough.
I hope this helps.

Hi Ayed,
The issue is that the battery thermal management in the MR1100 is too conservative. It stops charging due to "overheating" because the "hot" temp threshold is set too low. This is a known issue with this product. This product unfortunately was not designed for hot climates (I wonder if the AUS or EUS versions are any better)
This is a simple software change in firmware that Netgear seams unwilling to change. General consensus is that Lithium ion batteries are safe to charge up to at least 45C, some would even say 60C. But the MR1100 stops charging due to thermal sensitivity at like 35-37C.
Charging slower should help some. Leaving the case open and/or setting up a small fan also helps.
Occassionally there are also bad batteries that heat too much while charging.
AUS version isn't any better. We had a few Nighthawk batterys bulge as well leading to the batteries being removed.
We have started to replace all our always on Nighthawk devices with mains power devices now that additional devices are available from our carrier.
What mains power devices are you using? I'm interested in Nighthawk M1 performance from something without a battery. That is happy to run as a "Router" 24/7/365. M1's are great, if only Netgear just made an always on edition. Instead of just saying we designed these for hotspot short term use only.
We are testing the Huawei B618. Much taller device but it is mains powered.
