This may be a silly question, but do cases interfere with iPhone 7 antenna reception?

Thank you,

As long as you stick to electrically non-conducting materials (rubber/plastic cases), there will not be any interference. If a phone has antenna bands that should not be shorted, non conductive cases actually help the reception. Stay clear from metal cases, as others already pointed out.

I had a metal batman case for my phone, link at bottom if you want to see it. Just after I put it on I started having connection issues. I'd be in an LTE area and go from LTE to 3G to gsrc to Rogers-ext (basically connecting to other networks in a roaming like scenario).

On top of that, it would take longer to connect calls, reception was hit or miss too. And battery started going faster too.

Had the case about 3weeks, before taking it off.. I'm sad cause it's a beautiful case, just not very practical for phone usage.

Is it possible? Yes.
Does it generally happen? No.

If you're worried, get the case on Amazon Prime. Then out your phone into field test mode when you put your phone in the case. Then you can see how many decibels you lose.

Leather, rubber, silicone, cardboard or plastic you'll be fine. Metal ones can affect but it is down to metal finish and thickness.

Incidentally I saw a woven 'paper' handmade case at a craft fair, unfortunately upon investigation the paper was wrapped/wound over a frame that was metal, reception on my iPhone 6 dropped to 1 bar in the case!
