Symptoms
- Wireless charger doesn't connect as reliably with the case on
- Charging is slower or drops out more often with the case on
- Case has visible metal rings or thick padding near the back
- Charging is fine without the case but unreliable with it
Likely causes
- CommonCase thickness exceeding the charger's optimal charging rangeExtra-thick cases push the phone too far from the charging coil for efficient power transfer.
- CommonMetal components in the case disrupting the magnetic or induction fieldKickstands, card slots with metal, or reinforced corners can interfere.
- PossibleCase material or design shifting the phone's position on the padCertain case shapes make it harder to consistently center the phone on the coil.
- Less commonA worn-out magnetic ring in an older case losing grip strength over timeRepeated use and drops can weaken a case's magnets on phones with magnetic wireless charging.
What to do
- Try charging with the case removed entirely to establish a baseline.
- Check whether the case is specifically labeled as wireless-charging-compatible.
- Feel and check whether the phone centers itself well on the pad, or shifts around loosely.
- Remove any wallet attachments, cards, or metal accessories from the case during charging.
- Try a different, confirmed wireless-charging-compatible case if available.
- Clean both the case back and the charging pad of dust or residue.
- Note if the case is old or has been dropped often, since its fit or magnets can degrade over time.
- If a compatible case still charges unreliably, consider it a case issue rather than a phone issue.

When to call a pro
This is a case compatibility issue; no repair is needed unless the phone fails to charge well even case-free.
