The battery was 68% or 67% and suddenly (I did nothing special, I checked the battery after reading several minutes) went to 52%. Then it was normal again. Today the battery was on 42% and suddenly went to 31%. It seems to be normal again.
Anybody experienced that?

Yes, I've had a KA1 since last October and just recently started to think a charge maybe wasn't lasting as long. Checked over 3 discharges from 100% to 10% (when the reader insists you recharge) and those sudden drops happened every time. Twice each cycle it dropped about 12-15% while just reading. I'm suspecting its a battery calibration issue as it happened during a period of reading with no other activity, so a whole cycle is needed for comparison.
Anyway it looks like I get ~11 hours reading from 100% to 10% (90% as this is the actual time between recharging- ~12hrs if it was fully discharged). Sounds low compared to the 15 hours Kobo quotes - however the discharge rate really depends on the screen turns in this time - literally mileage may vary from person to person!
I read quite fast and keep my font size a little larger because of eye problems - so more screen turns; but I also reduce margins and line-height to cut back page turns.
And just realised that so far I haven't collected some essential info to get good figures on the screen turn rate! I'll report again in a few days after the next full discharge cycle.
