Guys...I have been doing some calculations. Here's my screenshot... it says that I'm at 41% down from 85% (I'm using the in-built battery charge limiter). The SOT is at 200 mins. I.E. in 44% of battery usage, I have achieved 200 mins of SOT. So, wouldn't 100 to 0 mean 7.5 hours of SOT...sooo...is the battery life bad? Or are my calculations really off?
