Using a ThinkNode M3 (nRF52840 + LR1110), I encountered the following problem: the companion only lasts 24 hours. The device has a 770mAh battery. This is obviously too short a battery life for this hardware.
I disassembled the device to measure directly on the battery cable:
I see a constant consumption of 28mA.
After sending a message via lora for a while (about 30 seconds), the consumption remains at 34mA.
At first, I thought the GNSS was active, but this is not the case. With GNSS active, I see a consumption of 50mA.
The device has thinknode_m3_bootloader-0.9.2-OTAFIX2.2.uf2 and ThinkNode_M3_companion_radio_ble-nightly-47154f0.zip installed.
upd. Current consumption on the official 1.17 ( ThinkNode_M3_companion_radio_ble-v1.17.0-727fc05.zip) build has not changed.
I also noticed that the battery voltage is being detected incorrectly; the app shows 4.80 V when the actual voltage is 4.26 V.
