Do phone cases affect wireless charging?
Short answer: not for typical slim cases. Qi wireless charging works through any thin, non-metal case — plastic, TPU, silicone, hybrid — because the electromagnetic field passes through them. Trouble only starts with very thick, metal, or battery-equipped cases. Magnetic snap is a separate question entirely: it needs a magnet ring built into the case, which most slim designer cases (including Miarobi's) do not have unless explicitly stated.
Do phone cases affect wireless charging?
For most cases, no. Standard Qi wireless charging works through any thin, non-metal case — including TPU, polycarbonate, silicone, and hybrid designs up to roughly 3mm thick. The charger's electromagnetic field passes through plastic without meaningful loss. Charging only becomes a problem with very thick cases (>3mm), cases with metal plates or magnetic credit-card holders, or rugged cases with built-in batteries.
Will the case slow down charging?
Slightly, sometimes — a thicker case increases the air gap between the charging coil and the phone, which can reduce efficiency by a few percent. In practice, you won't notice it for everyday overnight or top-up charging.
What about MagSafe magnetic snap?
Magnetic snap is separate from wireless charging. A MagSafe puck will still wirelessly charge through any thin case, but it will only magnetically attach if the case has a built-in magnet ring. Most slim designer cases — Miarobi's included — are wireless-charging compatible without the magnet array, unless the product page specifically lists one.
Are Miarobi cases wireless-charging friendly?
Yes. Every Miarobi case is a slim dual-layer TPU + polycarbonate shell with no metal components, so Qi and MagSafe pucks charge through them at normal speed.
