Re: Battery goes down WAY too fast on ESP

Based on your discharge graph, you are in the upper part of the discharge curve which is very nonlinear. So 50mV drop in this region is basically nothing to worry about, you may then experience weeks at 3.7V without a sign of depletion. In fact, voltage is not a good indicator unless you personally ...

I wouldn't be so sure about someone's ability to copy Bosch's MEMS technology. Even if someone in China could mimic it, I don't see a ma...
