How to attach a phone strap to any case
Phone straps fail at the attachment point, not at the beads. If the connection is wrong, a $30 strap will drop a $900 phone within a month.
There are two ways to attach one, and which you use depends on your case.
If your case has a lanyard hole
This is the easy case. Thread the strap's loop or clasp through the hole on the side or bottom of the case, then pass the other end of the strap through its own loop and pull tight.
The lanyard hole is built into the case, so it is as strong as the case is. A hole in a hard plastic shell holds better than one in a soft silicone case that stretches.
If your case has no hole
You need a tether tab, also sold as a phone lanyard patch. It is a thin strip of plastic or fabric, about 0.6mm thick, that goes between the phone and the inside back of the case. A small loop pokes out through the charging port or the bottom edge, and the strap clips to that.
The tab works because the case clamps it against the phone. The load is spread across the whole back of the case rather than one small hole.
Two things matter when you fit one. Put it on the bottom rather than the side, so the strap hangs down when you hold the phone. And check that the tab is not covering the charging port or the speaker.
Will a tab stop wireless charging
With most cases, no. The tab is 0.6mm and sits at the edge, away from the charging coil. If your charger is fussy about distance, take the case off when charging. That is a case problem rather than a tab problem.
Loop length matters more than people think
A strap that is too short sits tight against the wrist and pulls when you reach for something. One that is too long swings and catches on door handles.
Around 22cm of internal circumference fits most adult wrists with enough slack to slide off. For a phone charm that hangs rather than loops, 15 to 18cm of hanging length is the usual range.
Check it monthly
Tug the attachment point once a month. Cords stretch, tabs slip, and clasps bend. A strap that has started to give at the join is a strap to replace, not one to keep using.
The beads rarely fail. The connection is where the risk lives.
If the phone does drop
A wrist strap reduces the chance of a fall but does not prevent one. The pattern that works is a strap plus a screen protector, because the strap catches the phone and the protector catches the corner.
Proyoo phone charms and wristlets ship with both a side-hole connector and a 0.6mm tether tab, so they fit cases with or without a lanyard hole.
