Keep a metal bracelet off a wireless charger and out of the space between the phone and the charging surface. Jewelry in the charging area can become warm or interfere with charging. Wearing a bracelet while you hold the phone is different from leaving a chain on the pad. A magnetic clasp is a separate matter. It can affect the phone’s compass and camera, and if you have an implanted medical device, ask your care team about it.
Key facts
- Apple’s iPhone safety information names jewelry, keys, coins and batteries as metal objects to keep off a wireless charger, because they may become warm or interfere with charging.
- Foreign object detection is a charger safety feature, not permission to leave a bracelet on the charging pad.
- In a Qi2 magnetic charger, the magnets only line the phone up; the coils do the charging, according to the WPC.
- A magnet close to the phone can affect compass accuracy, so move a magnetic clasp away if a heading drifts.
Does a metal bracelet affect MagSafe or Qi2 charging?
A loose bracelet on or beside the charging surface is the first thing to move. Apple’s iPhone safety information names jewelry among the metal objects to keep off a wireless charger. Its MagSafe instructions call for a flat surface clear of metal and other foreign material; its wireless-charging guide says to keep objects out of the space between phone and charger.
Give a bracelet you remove at night a place beside the charger, such as a small tray. When setting the phone down, look for a loose chain or clasp that could slide toward the pad. Don’t put jewelry on the charger to see whether it interferes.
Qi2’s alignment magnets do not make loose jewelry part of the charging system. The WPC’s explanation of magnetic chargers distinguishes the magnets that align the phone from the coils that transfer energy. Keep the same clear charging space around a magnetic pad.
Why metal between the phone and the charger is the real issue
The WPC’s 2021 introduction to Qi v1.3 explains that the charging field can induce currents in exposed conductive objects, making them heat up. Its examples include coins and keys. A bracelet left in that field counts as a foreign object.
The same document describes foreign object detection and tests with reference objects in reference scenarios. That doesn’t tell you how your charger will react to a particular bracelet or clasp, so keep jewelry clear and don’t test it on the pad.
Can a magnetic clasp interfere with a MagSafe or Qi2 phone?
A magnetic clasp is not one of the alignment magnets specified for the phone and charger. Keep it clear of the charging surface along with any other loose accessory. Apple’s charging instructions also say objects between the phone and charger can reduce performance, though they don’t mention bracelet clasps.
Away from the charger, Apple’s compass guide says compass accuracy can be affected by magnetic or environmental interference. If a heading drifts while a magnetic clasp is close to the phone, move the clasp and check again.
Whether the clasp keeps the bracelet on your wrist is a separate question, covered in our comparison of magnetic, screw, clip and lobster clasps. To identify your closure, see bracelet clasp types with pictures.
If you have an implanted medical device
With a pacemaker or other implant, ask your care team about magnets, including those in phones, chargers and bracelets. Take a magnetic bracelet off before an MRI.
Bracelet types compared with a MagSafe or Qi2 phone and charger
The table covers charging and magnets only. For case fit and styling, see our phone-case guides.
| Bracelet type | On the charger or between phone and charger | In your hand, away from the charger |
|---|---|---|
| Steel cuff or link bracelet, no magnets | Metal object: keep it off the pad and out of the gap; it may warm up or interfere with charging | Keep it clear of the charging surface |
| Chain bracelet with a lobster or box clasp | Same metal caution; a loose chain can slip under the phone and stop it sitting flat and centered | Keep it clear of the charging surface |
| Bracelet with a magnetic clasp or magnetic beads | Keep it off the pad and out of the gap, where magnetic objects might reduce performance; metal parts count as foreign metal | A magnet close to the phone can affect compass accuracy |
| Leather, cord or bead bracelet with nonmagnetic metal caps or clasp | Small metal parts still count as foreign metal on the pad | Keep it clear of the charging surface |
Check the spot where you charge your phone
Look at the pad or MagSafe charger you use every day. If charging often stops or slows, clear the pad of metal before suspecting the phone. Look your charger up in the WPC’s certified products database, which lists certified products by WPC ID. If your case also carries rings, tabs or a strap attachment, add them and your bracelet to the charging row of the worksheet in our guide to choosing a phone case to wear with bracelets.
Frequently asked questions about bracelets, magnets and MagSafe phones
In an archived support note, Apple explains that lens-position sensors in some iPhone cameras respond to magnetic fields. A magnet near them can interfere with or temporarily disable optical image stabilization and closed-loop autofocus, and the camera keeps taking photos without those features. Apple advises avoiding accessories with magnets or magnetic metal near the rear cameras. Apple describes the effect as interference or temporary disabling; the note does not discuss permanent damage.
