The battery drain issue has still not been resolved.
Please issue a device patch or firmware update to fix the issues with the battery draining while device is in standby as well as the issue where the device cannot be used and recharged at the same time.

Thanks for reaching us here in our community forums.
We'd like to further check, could you send us the Model number of your Yoga Book? Are there any changes/updates prior to this issue We'll wait for your reply.

Thanks for getting back to us. Could you try to disconnect from WiFi for an hour or two on a standby mode? Also, observe it when connected to WiFi on a standby mode with the same time time duration. Kindly, take note how many percentages deducted in that duration so we can see the difference and how fast the battery drains. We'll wait for any updates.

I haven't tried the steps with Wifi yet, but I typically set Wifi to turn off when the device is sleeping and I've still had the issues with random, rapid battery drain. I also leave it in airplane mode so none of the radios are on while it's sleeping and only the Wifi turns on when the device is in use.

Hey there, XSYLUS!
We have found a similar concern in this forum discussion https://forums.lenovo.com/t5/Yoga-Book-Android/Yoga-Book-battery-drain-with-Android-7/m-p/3850946#M1... and you can try the suggested solution by one of the community members. Let us know how it goes.

Thank you. I have read and tried this method.
Two issues that arise from this however are that: 1) it's not a 100% working solution and 2) this clearly shows that there's a glitch in your launcher that needs to be addressed.
Rather than having your customer's avoid using a feature, it seems the better option is to fix the issue.
