I've had the same problem with every ZenFone I've owned (or at least the last 2 phones, ZenFone Laser 3, ZenFone 4), it won't download or update apps while it's charging. I thought it might have been a setting on android but the only post I've found that someone has had a similar issue is a forum post in the ASUS forum from over a year ago which never got an answer on how to fix the problem:

I've tried everything that was suggested. The only time I've got it to work is sometimes when I trick the phone buy unplugging it which starts the download and then plugging the phone back in. It also sometimes works when I power cycle the phone. It's not the end of the world but it's definitely an annoyance, so if there's something I can do to fix it I would love to know what it is. Any help would be greatly appreciated.
