Shaoshupai Lists Upgraded 0.17mm Maijinta Glass Film, Pairs It With Jizhi E-Ink Case for iPhone 18

The upgraded film increases thickness from 0.13mm in the first generation to 0.17mm, aiming to keep a light feel while improving durability, the article says. It has passed TÜV Rheinland certification. The tests covered display indicators such as haze, transmittance and ambient contrast, as well as durability items including high and low temperatures, wiping with 75 percent alcohol, steel wool friction and artificial skin scratching. After the tests, the total reflectance attenuation ratio remained above 50 percent, according to the article.

The article says the film uses 3D hot bending to better fit the slightly curved edges of recent iPhone screens. Edge handling is important because many high-frequency iPhone gestures pass through the screen edges. The increased thickness makes the edge slightly more noticeable than the 0.13mm version, but the article says it does not significantly affect daily swiping, returning from the sides, switching apps from the bottom, scrolling feeds or moving between apps, with no obvious sharp edge feel.

The upgraded Maijinta anti-reflective film continues to use a magnetron sputtering process and has an average transmittance of 96 percent, the article says. In stable office light, documents, messages and web pages remain clear, with little difference from a high-definition film. Outdoors, the difference is easier to notice: under strong sunlight, the screen still reflects light, but the image content is less affected by ambient light, making routes and text easier to read. The article also says fingerprints left during commuting, messaging and video watching are not very obvious and can be wiped away with a tissue, while sweaty fingers do not create a stiff dragging feel when sliding.

On the back, Jizhi's e-ink phone case uses a 400×400-pixel electronic ink display with 212 DPI, similar to an entry-level e-ink reader. The article says the display is sufficient for various image materials and that image transfer speed has improved over the previous generation, with one transfer completed in about 20 seconds at the fastest. The case comes in five colors: lunar rock white, deep space gray, sea salt blue, berry red and slime green. This generation adds a lanyard card slot and includes a dedicated lanyard piece. The raised magnetic structure on the back retains MagSafe compatibility, works with MagSafe accessories and does not interfere with wireless charging, according to the article.

The article notes a tradeoff between film coverage and case edge space. The upgraded Maijinta film has high screen coverage, which reduces exposed areas and makes the visual and tactile transition more natural. But fuller coverage leaves less room for a case edge and demands greater precision in case design and dimensions. When using other full-coverage cases, the article occasionally felt slight pressure between the case edge and the film. With the Jizhi e-ink case, edge space was controlled precisely, retaining full wrapping of the phone frame while leaving suitable room for the film. After repeated installation and removal, no film lifting or edge warping occurred. The article adds that users who habitually use full-coverage cases should pay attention to edge clearance.

For buyers choosing a glass film, the article suggests that a high-definition version can meet daily needs for mainly indoor use, while users who commute often, take outdoor photos or check navigation and care more about screen readability under strong light can consider the AR version. The upgraded 0.17mm Maijinta film is compatible with iPhone 18 Pro, iPhone 18 Pro Max, iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, iPhone 16 Pro, iPhone 16 Pro Max and iPhone Air. The Jizhi e-ink phone case tested in the article is mainly for the iPhone 18 series. For users who want protection and a back that can change with their preferences, the article says they can choose from the available colors and patterns.
