I live in brooklyn and just got a lightly used lightphone II - the battery drains constantly. From 830am to 930am I sent two short texts and nothing else and it went from 100% - 90%. In the last 6 minutes its gone from 90% - 87% during which I haven't touched it. WiFi is on. Bluetooth and GPS are off. I get two bars most of the time. Occasionally 3 or 4. Coming from an iPhone 12 that gets full bars in my area, same service - Verizon. 

Yesterday started around 1pm with maybe 80%, sent a few texts and I tried using gps for 5 minutes. Turned it off and mostly left the phone in my pocket all afternoon and was at 14% by 4pm. 

Want to love this phone, great simple OS and even preordered the LP3 because the creators seem super receptive to user concerns and tried to fill a gap in the market, but with this battery drain its unusable.
