    I just got my juice pack plus for my i5s. The instructions say to let the phone drain to 20% before turning the case on. And then turn the case off when the phone reaches 80%. I know a few people with battery cases and they leave them on 24/7.

    For those that have a battery case what is the best practice.

    My wife has one and basically she does what the instructions say, use it as a charging mechanism. When the battery on the iPhone is fairly drained, flip the switch to charge it and when its done charging, turn it off

    I normally leave my juice pack off until my phone is down to about 5-10% and then I turn it on. Once it hits around 70% I switch it off and save the remainder juice for if I need it later.

    I brought mine back. It only charged my 5s like 60%. It was supposed to be 100%. I heard it works right for the 5 but the 5s battery charges differently or something.

    Their site says it works for the 5s

    "2100mAh battery case with added power and protection made for iPhone 5s / 5. Equipped with up to 120% extra battery to make it through the longest flights or busiest weekend"

    Not saying it doesn't work but it only charges half of what it claims it will.

    Hmm. The 5s is only 120mah more than the 5. Maybe you got a dud.

    Has anyone had any issues with the camera flash getting reflected off the case? I haven't personally seen it but a friend has told me it happens to him.

    Come to think of it the juice pack plus is 2100mah and the i5s is 1560mah. So I'm pretty sure you just got a dud. Or you were using battery intense apps and the charge was working against your usage

    when my phone gets done to around that 20% area i usually turn the case on and just let it go, if its gets to 100% then i shut it off but if i noticed the phone at around 80-90% then ill turn it off and save some juice in the pack incase i need it again.

    I heard that you are supposed to do something like charge from 20 or so to 60-80% then turn the case off and do that again to get the most out of a battery case. Charging from 80%+ takes longer I find.

    I follow what is recommended on their website. 40 through 80%.

    My thought is it makes more logical sense to have the case on all the time. The reason is your phone will constantly be at 100% and then when you see the phone battery start to drain you know that you only have phone battery left. Versus draining and charging and not really knowing what is left

    Anyone have any issues after taking the case off and putting it on several times? I have taken mine off a few times to clean the phone. Does it get loose after several installations

    I think you're wasting the mophie battery by keeping it on past 80%, per their website.

    When I had the helium case I was able to charge from 20% to 80% shouldn't this case get you a lot more

    Amazon specs said 80%. If you are using the device as you are charging that will be that 20% that you did not get.

    I've read some reviews on this and another battery case claiming that the case made their phone drain faster. Anyone have this experience?

    Could of been that the phone was heating up causing the battery to drain faster. Batteries drain faster in heat.

    My wife noted this shortly after she put the case on. Tbh, I thought it was just her, but now that you mentioned it, I wonder if its a more widespread issue.

    Does this look about right? 1.5 hours of usage and I'm at 81%

    Actually batteries drain faster in the cold not the heat. That's why you see a lot of people having battery problems with their cars in the dead of winter.

    Well I was using my phone pretty non stop for 1.5 hours and on a wifi connection from the flow below me. With 1 bar of 1x playing graphics intense and network intense games. So going from 99% (dropped 1% immediately after unplugging) to 81% actually doesn't sound terrible.

    I've since turned off the battery percentage because at this point it really doesn't matter. When the icon goes red I'll turn the case on.

    Not sure about that. I've always been told cold preserves the charge. If you think about it the electrons bouncing around gives the charge right. And if you hear the battery up they bounce around faster aka drain. Cooling the battery would slow them down.
