In nearly five months I think I've needed to recharge during the day twice. Once was a day I was sticking lots of bits of card together and I realised too late that the screen was switching on each time. Not sure what the issue was the other time but I think it was just after updating the system and maybe it was connected to that.
Generally I end the day on at least 30-40% though.
