    I got a Mophie juice pack plus (Biggest one with 2100 MaH) for Christmas, for my iPhone 5s. It works perfectly but when I put the case in, signal drops either to No Service or to one dot. I take the case out and signal goes back as normal. Put the case on again and same problem appears. Any clues about why it happens?

    Well known issue with these battery cases.
    I hate those things.

    EMI is why it happens. Any case that contains metal will ruin your signal. Nothing you can do except not use the case or return it.

    As in the crappy country I live in there are no refunds, I'll ask to the Apple reseller that sold it to me (no Apple stores as well here) and if he gives me an useless answer I'll exchange it for another product of equal value. Seems there is nothing else I can do unfortunately... Question though: Why doesn't any internet review mention this deal breaker issue?
    Thanks for answering, and Merry Christmas.

    Yes cases that have metal in them, especial battery cases block signal strength. Exchange it for an external carry along flat back up battery. You can give your phone a charge any where any time and since it is not wrapped around the phone won't interfere with signal. This way you keep nice slim phone and still carry extra power with you. Added feature if you have a laptop or tablet, you can charge those as well from this extra battery pack.

    I believe the official apple battery case has signal boosters inside it, i assume that there should be some third party cases with this feature as well?

    Think the official Apple battery case is only for the 6 and 6s. I suspect even with booster antennas some signal loss will still take place. Especially if they are passive boosters, which I believe they are.

    Unfortunately even Apple can't violate physical laws that reduce radio wave propagation inside metal objects. Look up faraday cage.

    By adding a battery case that reduces signal, the radios turn up higher, using more electricity, sort of defeating the added battery in first place. Nothing would beat a phone with external antennas, sticking up outside the case. Remember those. But the form factor says no antenna masts any more.

    I think calling them boosters is a bit generous. More like built in repeater antennas to help channel signals around metallic parts and battery itself. Think I read it in the teardown. Not sure now, too lazy to look it up.

    I'd like to hear some input from people that have and use it.
    I bet signal is still impacted by the particular case.

    You live in the country so signal strength is already a sort of premium. I'll bet that in the city the signal reception is strong enough to overcome whatever limitations the case may bring.
    You see there are more than one band used to handle communications, a easy sort of descriptor is a channel. These various channels are all used as a sort of fail safe since reception will vary from location to location. Some channels may be strong in one area but not another but as you move strength will decrease and increase. Out in the country instead of, say, five channels to connect with you may be limited to just two or even one.

    Off the top of my head, I can only remember one article about a case with signal boosters. I can't remember its brand or name though. If its up to me, I would go with the official Apple case

    Good reception with no case, bad with case. . . . There is you clue.

    Get rid of the case.

    Yeah, if I was in the US That'd be easy, but there are no refunds here. I guess I'll try to see if it keeps impacting signal. if it does, I'll exchange it for something else. I appreciate all answers, thanks everyone.

    What country do you live where you cannot return a product with valid receipt?

    Sorry bud, hope they at least let you exchange it for something else. Store credit maybe.

    Or a battery pack and lightning cable. Better than nothing.

    Yes, agreed don't see how it can't be impacted to some degree. Metal banded cases had impact as I recall. And that was just the band rest was plastic.
