Switched it on 24h hours later on January 8th, 9:30... and the battery was at 55%.
That's from 95 to 55% in 24 hours is -1.67% per hour, which is 59.88 hours of sleep time, or only 2.5 days. This time, I really have no clue whatsoever as to why this is happening.
Bad battery after all? But then why did it seem fine yesterday after getting rid of that kepub? Sigh
Maybe it's just the battery meter. It is said that the calibration of the battery meter can take a few cycles to "learn" how the battery behaves and become accurate. If you've only had a few charge discharge cycles, maybe it is still learning?
