With the new <a href=\"https:\/\/www.androidauthority.com\/samsung-galaxy-z-trifold-hands-on-3624467\/\" rel=\"nofollow noopener\" target=\"_blank\">Galaxy Z TriFold<\/a>, Samsung has managed to keep the phone slim, measuring only 12.9mm thick when folded and just 3.9mm when open. Achieving this slim design required impressive engineering, especially when it came to powering the device without needing to plug it in.<\/p>\n<p>Don\u2019t want to miss the best from Android Authority?<\/p>\n<p><a href=\"https:\/\/andauth.co\/AAGooglePreferredSource\" class=\"e_rm\" target=\"_blank\" rel=\"noreferrer nofollow noopener\"><img class=\"e_jg\" decoding=\"async\" loading=\"lazy\"  title=\"google preferred source badge light@2x\"  alt=\"google preferred source badge light@2x\" src=\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2025\/12\/google_preferred_source_badge_light@2x.png\"\/><img class=\"e_jg\" decoding=\"async\" loading=\"lazy\"  title=\"google preferred source badge dark@2x\"  alt=\"google preferred source badge dark@2x\" src=\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2025\/12\/google_preferred_source_badge_dark@2x.png\"\/><\/a><\/p>\n<p>The standout feature here isn\u2019t the hinge or the screen. Instead, it\u2019s a custom wireless charging module made by Witz, a company that started as part of Samsung Electro-Mechanics, <a href=\"https:\/\/www.etnews.com\/20251215000400\" target=\"_blank\" rel=\"noopener nofollow\">ET News<\/a> reports (via <a href=\"https:\/\/www.sammobile.com\/news\/galaxy-z-trifold-wireless-charging-more-details\/\" target=\"_blank\" rel=\"noopener nofollow\">SamMobile<\/a>). Standard wireless charging coils are too thick for a device that unfolds to under 4mm. Cramming a regular module into the Galaxy Z TriFold would have either compromised the battery size or made the phone uncomfortably chunky.<\/p>\n<p>Samsung\u2019s solution was to commission Witz, a longtime supplier for the Galaxy S and Z series, to create an ultra-slim charging coil. According to Witz, its slim wireless charging module matches the thin design and structure of the Galaxy Z TriFold.<\/p>\n<p>What does this mean for everyday use? The phone offers 15W wireless charging using the Wireless Power Consortium\u2019s (WPC) Qi standard. This is the same as the current <a href=\"https:\/\/www.androidauthority.com\/samsung-galaxy-z-fold-7-review-3584443\/\" rel=\"nofollow noopener\" target=\"_blank\">Galaxy Z Fold 7<\/a>, but it doesn\u2019t quite hit the rumored speeds of the upcoming Galaxy S26 Ultra, which <a href=\"https:\/\/www.androidauthority.com\/samsung-galaxy-s26-series-wireless-charging-leak-3614564\/\" rel=\"nofollow noopener\" target=\"_blank\">leaks suggest could jump to 25W<\/a>.<\/p>\n<p>While the marketing materials mention \u201cQi2 Ready,\u201d there is a limitation to this. The phone does not have built-in magnets like Apple\u2019s MagSafe or fully <a href=\"https:\/\/www.androidauthority.com\/google-pixel-10-qi2-pixelsnap-accessories-3586593\/\" rel=\"nofollow noopener\" target=\"_blank\">Qi2-compliant devices such as the Pixel 10 series<\/a>. The charging coil works with the Qi2 standard, but you will need a special case with magnets to attach magnetic chargers and wallets to the back.<\/p>\n<p>The phone is equipped with a 5,600mAh battery split into three cells, supports 45W wired charging, and offers 4.5W reverse wireless charging to charge your earbuds.<\/p>\n<p>Right now, the Galaxy Z TriFold is available in South Korea and China. However, US buyers should start getting themselves ready, as it is <a href=\"https:\/\/www.androidauthority.com\/galaxy-z-trifold-us-availability-offers-3621193\/\" rel=\"nofollow noopener\" target=\"_blank\">expected to arrive in the United States<\/a> in the first quarter of 2026.<\/p>\n<p>Thank you for being part of our community.
