Reliable Protection – With raised edges and tempered screen protector
Raised edges surround both screen and camera to reduce impact on contact points, while the package includes a tempered glass screen protector installed by the user. Flexible TPU construction absorbs shocks and guards against scratches and everyday knocks.
Secure display and camera protection reduces the chance of visible damage from drops and abrasion. Practical for pockets, bags and frequent outdoor use.
Simple Charging Control – With one-button activation and four LED indicators
A single power button starts and stops charging, while four LED indicators show remaining charge in roughly 0%, 25%, 50%, 75% and 100% steps. Charging logic prioritises the phone first, with the case charging itself only after the phone reaches full.
Clear visual feedback makes it easy to monitor battery levels and avoid wasted cycles. Phone-first charging keeps the handset powered during top-ups without manual juggling.
Easy Fit and Removal – Thanks to flexible TPU top and slide-in design
The soft TPU top section bends back to allow the phone to slide in from the top down, and removal is performed by pushing the phone out from the bottom with the palm. The internal shape is tailored for 6.1-inch iPhone models listed as compatible.
Swift installation and removal suited to everyday swapping without forcing or excess wear. A secure, snug fit helps prevent accidental slips while carrying.
