Agreed, this actually sounds like spot-on for a common use case: you've got your laptop with you, you've been working a while or gaming and you close it as your battery starts to ebb. But a little while later, you realize you need to check your calendar or email for something for your upcoming meeting/date. Open up the laptop, find the info, close it again. You really didn't need 100% poer to read an address, did you?
