A new iPhone costs a small fortune, but its accessories get picked in a few minutes based on the price and the photo on the product page. Yet it is precisely the boring-looking parameters that make the difference between a screen protector that lasts a year and one that starts peeling off at the edge after a month.
For each of the five accessory categories for the iPhone 18 Pro and 18 Pro Max, we go through the parameter that determines quality: what it means, how it is measured and why you should keep an eye on it. The recommendation then follows from the numbers, not from the price list.
Five categories, five questions. Skip straight to yours:
- Screen protector: which one to choose when protectors differ in coverage, edges and the number of pieces in the box?
- Lens protection: why deal with it separately when the case has a raised edge?
- Case: what about a case really determines protection, and what is just a description of the material?
- Wall charger: how many watts can the phone really use from it over a cable?
- Wireless charging: when do you get 25 W and when do you stay at 15 W?
What is not in the iPhone 18 Pro box
The box of a new iPhone contains the phone and a cable. There is no wall adapter and no protection of any kind, so for the first few days the phone usually rides around naked in a pocket and charges in the evening from whatever was left over from the previous phone.
You can buy almost anything separately, but the parameters that determine quality are not listed side by side on the product pages. So for each of the five categories, we pick one number or one property from which the recommendation then follows. No parameter guarantees anything on its own; what counts is how it combines with the way you actually carry your phone.
Screen protector: what full coverage and 9H hardness mean
With screen protectors, people compare the price per pack, but two other things decide: how much of the display area the glass actually adheres to, and how its surface behaves. That is what tells you whether it will last a year or start lifting at the edge within a month.
Coverage
Full coverage means that the glass covers the display from edge to edge, including the black bezel. The adhesive is a separate parameter: quality protectors have it across the entire surface, cheaper ones only around the perimeter, so an air gap remains under the centre of the glass, where rainbow spots appear and touch is less responsive. With glass glued only around the perimeter, dust also gets under the edge more easily.
The second parameter is the rounding of the edge. The 2.5D label means a chamfered edge on otherwise flat glass, while 3D glass follows the curve of the display all the way to where it meets the phone's frame. At Mobile Origin, all screen protectors are 2.5D except for the 3D AR PRO range.
Hardness
9H hardness is the highest grade of the pencil hardness test: a pencil of a given hardness is drawn across the surface under constant pressure to see whether it leaves a scratch. Apart from the number, it has nothing in common with a 9 on the Mohs scale, which is used to measure minerals. For the 3D AR PRO glass, the test is documented with a 750 g load; we looked at this in more detail in our article on screen protector hardness.
Drop tests cannot be compared across ranges, because each range is tested differently: 3D AR PRO with a 64 g steel ball from 120 cm, EasyGlass Privacy with the same ball from 120 cm three times in a row, and the Privacy two-pack from 150 cm plus edge pressure of up to 25 kg.
Privacy
A privacy filter lets light through only in a narrow cone. Head-on, the display stays readable; from the side, it goes dark, so the person next to you on the tram cannot read your message or your account balance. You pay for it twice, though: head-on, the image is slightly darker than under clear glass, and smudges and fingerprints are more visible on the privacy layer.
It makes sense on public transport, in an open-plan office and for banking. It does not make sense for taking photos or for videos you watch with someone else. You can choose between a single EasyGlass Privacy protector with a six-layer compression construction and the Privacy two-pack with a seven-layer one, each with its own product page for the Pro and for the Pro Max.
For normal everyday use, the Screen Protector, 2 pcs, Full Coverage, with Applicator comes out best on these three parameters: full coverage, 9H hardness, 2.5D edges and a clear finish that, unlike privacy glass, neither reduces brightness nor restricts side viewing angles. The applicator holds both the glass and the phone aligned with the cutout, so the risk of the glass shifting outside the frame is much lower, and the second protector in the box stays as a spare in case the first one goes on crooked, which is the most common reason for a failed installation.
If you want the very best feel from your new iPhone, you will reach for the premium 3D AR PRO. It follows the curve of the display all the way to the phone's rounded edges, so there is no sharp transition anywhere under your finger.
It is Corning glass that has undergone double ion exchange, its anti-reflective layer improves readability in direct sunlight, and its oleophobic surface maintains a water contact angle above 105° even after 10,000 abrasion cycles.
What a screen protector will not solve: a drop onto a corner that cracks the display underneath, or scratches on the edges of the frame, which the glass does not cover. For the iPhone 18 Pro Max, both the full-coverage two-pack and the 3D AR PRO have their own product page.
Lens protection: sapphire or tempered glass?
The camera module of the iPhone 18 Pro protrudes above the back of the phone, so a phone set down on a table rests right on it, and in a pocket it comes into contact with keys and sand. Apple makes the lens covers from sapphire crystal, which neither keys nor ordinary sand will scratch, but which cracks or chips when it strikes an edge. A damaged lens cover then does not show up as a mark on the phone, but as haze and starbursts around point light sources in every photo. It cannot be polished out.
Three numbers decide how good a lens guard is. A double-sided anti-reflective coating cuts reflectance to 0.2 to 0.4 % at 99 % transparency, so it does not add reflections of its own to the lens. An oleophobic layer with a 115° contact angle repels grease, so fingerprints stick less to the surface and are easy to wipe off. And a 0.2 mm gap between the guard and the case frame, in other words a case friendly design, is the reason why lens protection and a case are chosen together.
The second question is the material. Sapphire is a harder material than aluminosilicate glass, but it is also significantly more expensive. For everyday use with a case, 0.33 mm glass that is anti-reflective on both sides is enough; sapphire makes sense for anyone whose lens really takes a beating.
That leaves the design. Separate rings around the individual lenses let the shape of the module stand out and also protect it from the side, while a single full-coverage plate over the whole module is a little easier to apply and is the cheapest option. What a lens guard will not solve: a hard drop onto an edge. In that case it cracks just like the glass beneath it, except that you replace it for a fraction of what a camera module repair costs.
These parameters point to the Easy Lens Guard: 0.33 mm high-alumina glass, 9H hardness, 99 % transparency, a double-sided anti-reflective coating, a 115° oleophobic layer and a nine-layer construction including a metal frame and a foam seal. A single product page covers both the iPhone 18 Pro and the 18 Pro Max, and you can choose from four colours.
Case: what really protects the phone and what is just a description of the material
A hybrid case is not made of a single material. The hard polycarbonate back holds its shape and does not give when twisted, while the flexible TPU frame around the edge absorbs the energy of an impact and spreads it over a longer time. A single material cannot do both: hard plastic cracks and soft plastic bends, so over time the phone stops sitting firmly in it.
You can tell what a case really protects by its raised edges. The frame has to rise above the plane of the display and above the lenses, so that a phone placed face down on a tabletop does not touch it at all. This applies even when you already have a screen protector and lens guards applied: the raised edge is exactly what keeps them off the table.
On a case, MagSafe is not decoration but a parameter. It means magnets built into the back of the case, whose job is to line up the charger's coil exactly with the phone's coil. Only aligned coils let wireless charging run at full Qi2 power: through a case without MagSafe, the charger holds less firmly, slips out of place easily and the power drops. The same magnets also hold a car mount, a wallet or a stand.
With clear cases, yellowing is an added concern. Under UV light and grease from your hands, transparent plastic changes its tint over time; Easy Hybrid counters this with Bayer material featuring a nano layer, and it also has an Anti-Slip grip finish.
The Leather Magnetic Case addresses something other than durability: how the phone looks and how it feels in your hand. It is made of genuine cowhide from the Danish company ECCO, dyed using the aniline technique, so it keeps its natural pores and develops its own patina over time. No two pieces age the same way.
Inside, a microfibre lining protects the back of the phone, the buttons are metal and the whole case weighs 39 to 44 g. Like the hybrid case, it has MagSafe, so you lose neither wireless charging nor your car mount. You can choose black or dark brown, both also in a version for the Pro Max.
The Easy Hybrid MagSafe Case offers the most verifiable protection: a polycarbonate back with a TPU frame, reinforcement in all four corners, a 1.5 mm profile, raised edges above both the display and the lenses, Bayer material with an anti-yellowing nano layer and an Anti-Slip surface. There is a counterpart for the iPhone 18 Pro Max, and a matte black variant is also available.
Qi2 wireless charging: where the difference between 15 and 25 W comes from
Specifically: on a charger with the Qi2.2 revision, the iPhone 18 Pro gets up to 25 W, on an older Qi2 charger it stays at 15 W, and on an ordinary pad without magnets at 7.5 W. That is more than a threefold difference between the extremes, and it is the charger that decides, not the phone.
Qi2 achieves this thanks to MagSafe, that is, magnets that align the charger's coil and the phone's coil for you. Only an aligned coil allows higher power without the excess turning into heat: a phone placed askew charges more slowly, or not at all, even if the charger can do 25 W. We covered the standard itself in a separate article on Qi2.
Power level
For wireless chargers, several power levels are quoted: 5, 7.5, 10, 15 and 25 W. These are not steps that charging switches between, but ceilings for different phones and profiles: 5 W for basic Qi, 7.5 W for an iPhone on an ordinary pad, 10 W for some Android phones, 15 W for Qi2 and 25 W only with the Qi2.2 revision. So the original Qi2 tops out at 15 W. Even with a 25W charger, the phone does not charge at full power the whole time: as soon as the cell warms up or the battery approaches full, the power gradually tapers off. The difference from 15 W is therefore most noticeable in the first half hour.
That is exactly why it pays to check the revision of the specific model. The PW29 pad declares Qi2.2, the foldable PW36 lists Qi 2.2.1, and the PW37 only states Qi2 25 W.
Adapter
A common reason the phone does not get 25 W is a weak power supply. The adapter has to cover the input power the charger specifies: a 30 W USB PD adapter is enough for a standalone Qi2 25 W pad (Apple specifies 30 W or more for its MagSafe charger), while chargers for several devices need more. The PW29 pad needs 30 W at its input, and its box contains just the pad with a fixed 1.2 m cable; the foldable PW36 wants a full 45 W, and its box includes a 1 m USB-C cable but no adapter. A weaker power supply will not stop charging; it just keeps it at a lower level.
The form factor is then chosen accordingly. At 56 × 56 × 7 mm and 62 g, the flat PW29 pad is the simplest way into 25 W wireless charging on a bedside table, while the foldable PW36, at 145 g and Ø 64 × 18.1 mm when folded, is the slimmest 3-in-1 charger for a backpack.
Several products in the range can handle a phone, earbuds and a watch at once. For the desk, the PowerStand Pro 3in1 is a good fit: it holds the phone upright at 25 W, plus 5 W for earbuds and 2.5 W for a watch. Its main advantage is that the adapter comes right in the box, a GaN one rated 40 to 60 W, so you do not need to buy one separately.
If you also need a cable for your laptop alongside wireless charging, you will reach for the Foldable Charger 6-in-1 PW37: wirelessly, it delivers the same 25 W to the phone plus 5 W to earbuds and 2.5 W to a watch, and the separate USB-C2 port handles 100 W. Not everything runs at full power at once, though: the combined ceiling is 97.5 W.
GaN wall charger: why it is smaller and how many watts the phone can use from it
GaN stands for gallium nitride, a material that has replaced silicon in the charger's key switching components. GaN transistors switch faster and with lower losses, so less energy is wasted as heat and the charger can make do with a smaller transformer and less space for cooling.
You can feel the difference in your hand: at the same power, a GaN charger is smaller and lighter than an older silicon one and does not heat up as much under full load. Size, however, is just a consequence. The choice comes down to two other things: which protocols the charger supports and how it splits power between its ports.
Protocol
USB Power Delivery is an agreement between the charger and the device on voltage and current; PPS is an extension of it that can fine-tune the voltage in small steps, so the phone heats up less. The iPhone does not use PPS, though: it takes a fixed voltage (at most 15 V⎓3 A), and the iPhone 18 Pro now also supports AVS. So with an iPhone, what matters is which of these modes the charger's port offers. How the protocols differ across brands is covered in our earlier article on charging protocols.
Over a cable, the iPhone 18 Pro takes considerably more than wirelessly. With a regular PD adapter that can do 15 V⎓3 A, in tests it holds at around 41 to 44 W, and from a 20W adapter only around 19 W. Apple promises the fastest charging, 50 % in about 15 minutes, with an adapter of at least 60 W that supports AVS, i.e. continuous voltage fine-tuning under USB PD 3.2. Yet according to Apple, the phone itself takes at most 45 W, and the iPhone 18 Pro Max at most 54 W. The exact figure varies with battery level and temperature, so charging does not run at maximum the whole time, but it is precisely the first few tens of percent where you notice it.
That is exactly why it pays to look at the supported protocols, not just at the charger's maximum power. For example, the 67 W of the PW6 charger applies to Mi Turbo Charge for Xiaomi, Redmi and POCO phones; on the PD branch, the ceiling is lower.
Usually there is no cable in the box
With the PW21, MO19 and PW6 chargers, as well as the slim GaN one, the box contains the charger and a manual, nothing more. The cable is bought separately, and for the MO19 the specification says so explicitly. The only wall charger in this overview that comes with a cable is the PW3, and it is an integrated retractable one, 65 cm long.
Yet the cable matters just as much as the adapter. The USB-C label alone says nothing about the power it carries or its data speed, as we explained in our article on the differences between USB-A and USB-C. You will find cables with a stated wattage in the USB-C cables category.
Power distribution
The number on the box applies to a single port in use. The PW21 charger delivers 140 W from one port, 135 W with both USB-C ports in use at once (100 + 35 W) and 128 W with all three (65 + 45 + 18 W). As soon as one of the two ports in use is USB-A, the ceiling drops to 118 W.
With cheaper models, the drop is steeper: the slim 65 W GaN charger and the PW3 both deliver only 7.5 + 7.5 W when the second USB-C port and the USB-A port are in use at the same time. If you plug in a phone and earbuds as well as a laptop, the phone will only charge slowly.
That is why, with a charger that has a display, it pays to watch what it shows: the real-time draw of each port is the only way to tell that the power has been split differently from what you expected.
So the recommendation follows directly from the numbers a paragraph above. The GaN Wall Charger with Display PW21 holds 128 W with all three ports in use, so a phone, a laptop and earbuds all run at the same time without compromise. Its USB-C ports support PD3.1 and PPS, but AVS is not listed, so the iPhone 18 Pro charges from it at a fixed 15 V (around 41 to 44 W) rather than in the fastest mode with AVS. It is, however, a solid unit for the socket by your desk, not a charger you carry in your pocket every day. The cable is bought separately.
Quick comparison: five categories in one place
The table sums up what matters in each category and which product comes out best on these parameters.
| Category | What matters | Recommended pick |
|---|---|---|
| Screen protector | Full coverage and 9H hardness | Screen Protector, 2 pcs, with Applicator |
| Lens protection | Anti-reflective coating and gap for the case | Easy Lens Guard, Black |
| Case | Raised edge and MagSafe | Easy Hybrid MagSafe, Clear |
| Wireless charging | Power level and power adapter | Foldable Charger 6-in-1 PW37 |
| Wall charger | Power distribution across ports | GaN PW21 with Display, 140 W |
What to buy first
The order in the table is not a shopping list. The stick-on layers belong on a display and camera module cleaned straight out of the box; the case is chosen together with them, and charging can be sorted out at any time later.
- Start with the screen protector and lens guards. It is the lowest cost against the most expensive possible damage, and both are applied to a surface that has not yet had time to collect dust. The later you get round to it, the greater the chance that a micro-scratch from your pocket will already be trapped under the glass.
- Choose the case together with the screen protector. What matters is a raised edge above both the display and the lenses, and a 0.2 mm gap so that the frame does not clash with the lens guard. MagSafe in the case is also a prerequisite for a magnetic charger and a car mount to work later on.
- Leave charging until last. You can buy a charger at any time, and what matters here is different from protection: how many devices you charge at once and whether you want to carry a cable. Depending on that, you will end up with either a wall charger from the GaN category or a magnetic pad from the Qi2 technology category.
Frequently asked questions
Do I need lens protection if my case has a raised frame?
The frame protects the phone when it is placed on a flat surface, but not in a drop onto an edge or a direct hit to the camera module. A lens guard also costs a fraction of a camera module repair and can be replaced on its own.
Is 9H hardness the same as a 9 on the Mohs scale?
No. 9H is the highest grade of the pencil test for scratch resistance, while the Mohs scale measures the hardness of minerals from talc to diamond. They share only the number, so 9H glass is certainly not as hard as corundum.
Will my display get darker with a privacy screen protector?
Head-on only slightly, from the side significantly, which is exactly the point. Also bear in mind that fingerprints are more visible on the privacy layer than on clear glass.
Will a 140W charger charge my phone faster than a 65W one?
In practice, no: the phone only takes as much as it can handle, and its ceiling is set by its own electronics. The difference only shows when a laptop is also connected to the same charger: that is where you see how the charger splits power between its ports.
Why is my Qi2 charger not reaching 25 W?
The first thing to check is the revision: only Qi2.2 can do 25 W, plain Qi2 tops out at 15 W. If you have the right revision, the culprit is usually a weak adapter in the socket, temperature or the battery level. The PW29 pad needs 30 W at its input and the foldable PW36 a 45 W adapter, while the PW37 plugs straight into the socket.
Can I charge wirelessly through a case?
Yes, if the case is MagSafe-compatible and no thicker than the manufacturer specifies. Without magnets in the case, the charger holds less firmly, easily slips out of alignment with the coil and the power drops.
Can I apply the screen protector correctly on the first try?
With the applicator, yes: it keeps the glass aligned with the cutout and significantly reduces the risk of it shifting. That is precisely why the two-pack includes a second protector: the most common reason for a failed installation is crooked application.
Glossary of terms
- Full coverage – the glass covers the display from edge to edge, including the black bezel. Adhesive across the entire surface is a separate parameter; quality protectors have it, so not as much dust creeps under the edge.
- 2.5D and 3D edge rounding – 2.5D is a chamfered edge on otherwise flat glass, while 3D glass follows the curve of the display all the way to where it meets the phone's frame. 3D covers more, but copes less well with a thick case.
- 9H hardness – the highest grade of the pencil hardness test for scratch resistance. A pencil of a given hardness is drawn across the surface under constant pressure to see whether it leaves a scratch.
- Mohs scale – a ten-point scale of mineral hardness from talc to diamond. Apart from the number, it has nothing in common with the 9H pencil test, even though the two are often confused.
- Aluminosilicate glass – chemically strengthened glass with aluminium and silicon in its structure. Ion exchange introduces compressive stress into the surface, which makes the glass better at withstanding scratches and bending.
- AR coating (anti-reflective) – a coating that reduces reflections on the glass surface. On lens guards, it cuts reflectance to 0.2 to 0.4 % and reduces the risk of starbursts around lights in photos.
- Oleophobic coating – a surface treatment that repels grease. It is measured by the contact angle of a droplet, which is typically around 115° on quality glass and lens guards, so a fingerprint can be wiped off with a sleeve.
- Case friendly – a label for protection that leaves a gap for the case frame. On Mobile Origin lens guards, it is 0.2 mm, so the guard and the case do not lift each other.
- AVS (Adjustable Voltage Supply) – a USB PD 3.2 mode in which the adapter continuously fine-tunes the voltage to the phone's needs. It is precisely AVS that lets the iPhone reach its highest wired charging power.
