I've read about restarting bme service when battery charge drops suddenly to 4%. And it works. However, I found that it also affects when battery is charged: if I restart BME when battery reaches 100%, it drops to a lower level (e.g. 93%) and charing continues. If I keep restarting BME using a while loop with a small delay between restarts (70 seconds), it almost never reaches 100%.

I wonder what is really happening, and also if it is dangerous?! May it cause overcharging? Why it doesn't reach 100%?

(It seems that this way battery lasts longer, and sudden drops in charge level are smaller).
