When I fully shut down my iPhone 7 and I let it for several days , it auto discharge at something like 7% per day. After two weeks it is completely empty. It is still under garantie so I call Apple and they send the phone to the repair center. The first time they change a 100% battery by a 100% battery, the second time two days later the phone came back with a note that there nothing wrong with my phone.
When I let my iPhone 6S , after two weeks it is still a 99%.

Is it normal for an iPhone 7 to have such an auto discharge rate ?
If not what can I do , as the repair center does do it’s job ?

When you say "fully shut down", are you completely shutting the phone down or just leaving it in standby for those several days? If in standby and apps are updating in the background or other things are going on, it will drain the battery. I shut my iPhone 8 off when not using it and it does not drain the battery.

My iPhone 7 that I use for playing my music and as a backup phone does the exact same thing. I was thinking about taking mine in for a battery replacement, but after reading your post that may not fix it after all. My battery health is at 91% .

there's nothing wrong with your phone according to Apple even though there's something wrong with your phone.
If I turn of my iPhone (not a 7) it'll be at the same percentage the next day when I turn it on or maybe one percentage point lower.
My old iPhone 5 spare phone can sit in a drawer for months before I need to top it off again.
There's definitely something wrong w your phone/battery.

Something is wrong. If you turn your phone off it should not lose even 1% a day, 7% is ridiculous!

This is a common problem with the iPhone 7. My 256gb iPhone 7 does this also. I had the battery replaced by Apple even though it had good health, but even with a new battery, mine does this also. It's not a big problem since I charge my phones in the car and at the office and never let them get very low, but if I turn it off and leave it off it will be completely dead in a week's time. I've seen some other threads on this same issue and it seems Apple doesn't acknowledge it but it's real.

When I say fully shut down , it is really completely shut, no power at all. I have also an iPhone SE and an iPhone 6S, none of them have the problem. When I shut down my 6S, after a week , it is at 99%, when my 7 is completely empty.
Reading your comments, it seems to be a common problem with the 7... what can we do ?
