iPhone 7 smart battery case usage

[seanw1990]

Hi just curious as to what other members using the iPhone 7 smart battery case are getting battery usage and standby wise ? And also do you notice the battery percentage jumping down in say 4% at a time ? I mean if my case is at 90% and I do some Facebook or some web browsing then check again and the percentage is 86% for example is this behaviour normal ? Or through the night dropping a few percentage is this all normal and can other members confirm ? Would appreciate the feedback and help

I think the percentage drop is absolutely normal. It's like you're first wasting the case's battery. If you would use your phone's battery it would drain the same percentage.

I think your right , I think I'm overalls checking the percentage , but it's no doubt because the phone may be at 100% but the case is kinda on off charging and topping the case up constantly to 100% so the percentage drop would be like that ?
