I have a Lenovo Yoga 8 model 60043. Three weeks old. I charged the battery yesterday afternoon till around 10pm and it completed at 100%. This morning when I came to use it I found its down to 24%. I closed it down correctly last night going through the right procedure but just is case do you have any recommendations? This is not the first time I have found this happening, perhaps I'm doing something wrong. This is my first tablet and I'm still learning........!!
