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. ...
I fixed the reboot-loop by acquiring a 3.0 Amp USB-C charger (Deltaco brand). But I also noticed than when in my back pocket, the unit gets very hot from just one-two single devices connect and not really downloading anything. The battery drains quickly and is usually flat within 5-8 hours, so I need to travel with a fast charger in order to have a change to have it survive a whole day out of home. (I have the EUS version.)
Yesterday I bought a Nighthawk M1 MR1100-100EUS from Amazon Germany, i.e. the unbranded retail version sold in Europe, a brand new unit.
Still now in May 2018 the stupid problem is present that the battery cannot be charged while the device is in use as the battery temperature threshold is still as low as 40°C. Hello Netgear! This sucks big time!
At least I found a workaround: I can charge it by getting a cool pack out of the freezer and placing the M1 on top of it. This brings the temperature down and within a few minutes it draws about 10 Watts of power (1.8A @ 5V or 1A @ 9V with a QC charger) again. This is as good as it gets.

Agreed. Most resources I've found on the web suggest that 45C is considered very safe with little or no impact on longevity. Charge at higher temps is possible by battery life may be reduced.
Maybe Netgear will come out a with Gen4 device with a fan (-:
I also can't believe they have not solved this. I have 4 Nighthawk M1 units. I did find buying a bigger usb wall plug as recommended by another user really helped. Maybe it charges so fast the temp cut off doesn't engage as quick.
The one I'm using is this one, recommended on this thread: http://www.comsol.com.au/Products-by-Category/USB-Wall-Chargers/COWCSQ3WH_2
It also has enough power to run the unit without battery. Therefore enables the "remove battery" option which I usually will do if I know I'm going to be using the device heavily in an 3-4 day event. I never had a temp gun on me and never had time to figure out if tempreture is the cause of my problems. Removing the battery however with a sufficient power source seems the best workaround for me. Remove the battery without enough power the device will reboot when tries to get more power and it isn't available. Such as when you get plenty of poeple in the area and it needs more power to reach a mobile tower.
Come on Netgear, get it sorted out. At least in the new ones you are selling if it can't be sorted out with firmware alone.
I reported the problem to Netgear March 2017.
It's now May 2018.
Best official response I recieved was they didn't expect people to use it for more than a few hours at a time. Expecting people to only use the router as a pocket hotspot with occassional use.
That's stupid, it's a "Router" with a Gigabit Ethernet. A rather well performing router with GE and the best specifications for the Telstra mobile network (maybe other networks too). The bright spark that thought nobody would actually unleash it's capabilities should re-think how people use a performance portable router connected to a network with 200+mbit/s speeds.
