I got my Electron about a week ago. It’s already up and running!
The thing is that it takes about 1-2 minutes to get a connection (2G version, Europe, indoor). That seems quite slow to me, my smartphone takes about 5 seconds to connect to a HSPA+ network. This will probably be a big part of the battery consumption.
Is there anything I can do to reduce this duration? The Electron will be used to measure water temperature in a lake. It should wake up about once every 1-2 hours to connect, send a measurement and power down again. And all this as power efficient as possible.
