The Samsung Galaxy S25 Ultra is a large, glass-and-titanium flagship with a 6.9-inch display, a built-in S Pen and a camera array that is expensive to repair, which makes the right accessories less of a luxury and more of an insurance policy. In Australia the sensible starting point is a case, tempered glass and a charger that all match the phone and are held in local stock so you are covered by Australian Consumer Law and GST-inclusive pricing rather than a slow overseas import. Our Samsung Galaxy S25 Ultra accessories collection brings the model-specific gear together in one place.
This guide walks through the accessory stack in order of how much grief each item saves you: protection first, then the S Pen, then charging and power. Everything here is chosen for real Aussie use - hot cars, long commutes and a phone that costs a lot to fix.
Cases: the first and cheapest insurance
The S25 Ultra is big, flat-edged and heavy enough that a slip from bench height lands hard. Match the case to how you actually use the phone.
- Rugged / tough cases - reinforced corners and a raised bezel that keeps the screen and camera off the ground. Look for a case citing MIL-STD-810G drop testing (the US military-derived standard for tumble and drop survival) if you are on a worksite or often outdoors.
- Slim protective cases - a thin TPU or hybrid shell that keeps the phone pocketable while still adding grip and a raised lip. The everyday-carry choice for most people.
- Clear cases - to show the titanium finish; choose one that states yellowing resistance, because cheap TPU ambers under strong Australian UV within months.
- Magnetic / Qi2 cases - with a built-in magnet ring so wireless chargers and mounts snap on and align, even though the S25 Ultra does not have magnets built into the body.
Whatever style you choose, a raised front lip and raised camera rim are the two features that actually stop cracks.
Protecting the S Pen and its silo
The S Pen is one of the S25 Ultra's signature features and its most overlooked care item.
- Keep the silo clear. Grit dragged into the S Pen slot in a pocket or bag can jam the click mechanism. A case that shields the base of the phone helps keep the slot clean.
- Replacement nibs. The soft nib wears with heavy note-taking; a worn nib drags and can scratch a bare screen, which is another argument for a screen protector under it.
- Match your protector to the pen. The S Pen works best over a smooth, thin protector; a thick or textured film can dull the writing feel, so choose glass rated for stylus use.
Screen and camera glass
Screen protection
The S25 Ultra's flat display is well suited to full-cover tempered glass, which protects to the edge and gives a smooth surface for the S Pen. Look for a 9H-class scratch rating, an oleophobic anti-fingerprint coating and full touch sensitivity. Browse model-appropriate options in our tempered glass screen protector range and pick glass cut for the S25 Ultra footprint - protectors are not interchangeable between models.
Camera lens protection
The rear camera ring sits proud of the body and is usually the first thing to touch a table. A tempered glass camera lens protector adds a sacrificial layer over each lens. Choose one with clear cutouts aligned to the S25 Ultra's specific lens layout so it does not cause flare in night shots; a well-made protector has negligible impact on image quality, while a poorly aligned one can add glare.
Fast charging and wireless charging
The S25 Ultra supports high-wattage USB-C Power Delivery wired charging and Qi-standard wireless charging, so your accessories should keep up.
- USB-C PD wall charger - an Australian-certified charger with a Type I plug that delivers the phone's full supported wattage. A charger that only outputs low wattage will trickle-charge a battery this large.
- USB-C to USB-C cable - to carry the full current, the cable matters as much as the brick. A thin data-only cable throttles fast charging.
- Wireless charger - a Qi2 or magnetic pad is the tidy desk and bedside option. Explore our wireless charger range and, if your S25 Ultra case has a magnet ring, choose a magnetic pad so the coils always align for full speed.
Remember that wireless charging runs cooler and slower than wired, and in an Australian summer a hot phone will throttle either way, so keep the pad out of direct sun.
Grip, mounts and car use
The S25 Ultra is a wide, heavy slab of glass, and its flat sides make it easier to fumble than a rounded phone. A few small additions make daily handling safer and more useful.
- Magnetic car mount - if your case has a magnet ring, a magnetic vent or dash mount holds the phone securely for navigation without a bulky clamp. In an Australian summer, avoid mounting the phone in direct windscreen sun, which cooks the battery and triggers thermal throttling.
- Grip or finger loop - a magnetic grip stand doubles as a kickstand for watching video and reduces one-handed drops.
- Wall and desk mounts - Qi2 and magnetic desk stands keep the phone charging and visible while you work.
Matching the screen protector to the phone
It is worth being specific about fitment, because the S25 Ultra's flat display and S Pen make protector choice matter more than on a basic phone. Full-cover tempered glass suits the flat screen and gives the pen a smooth, consistent surface, but the glass must be cut for the S25 Ultra footprint - protectors from other Galaxy models will overhang or leave a bare strip. Check the listing states a 9H-class scratch rating, an oleophobic coating for fingerprint resistance, and full touch and pen sensitivity. If you use a rugged case with a tall lip, a case-friendly protector that sits slightly inset will avoid the edge lifting where the case meets the glass.
Cleaning and maintaining your kit
Accessories last longer with a little care, especially in dusty or coastal Australian conditions. Wipe the screen protector with a dry microfibre and only a lightly damp cloth for stubborn marks; avoid alcohol-heavy cleaners and hand sanitiser, which strip the oleophobic coating over time. Clear cases benefit from an occasional wash in warm soapy water to shift the grime that accelerates yellowing. Keep the charging port and S Pen silo free of pocket lint, and inspect cables for fraying near the connector, which is where heat and repeated bending do their damage.
Power banks for long Aussie days
A 6.9-inch display and heavy camera use drain a big battery quickly on a full day out. A power bank keeps you topped up.
- Capacity - a 10,000 mAh to 20,000 mAh bank gives one to two full recharges of the S25 Ultra's large cell.
- Output - choose a bank with USB-C PD output that can actually fast-charge the phone, not just a 5V trickle.
- Airline rules - Australian carriers cap carry-on lithium batteries at 100Wh without approval (roughly 27,000 mAh at 3.7V), so check the Wh rating before you fly domestically.
How to prioritise on a budget
You do not have to buy everything at once. If you are spacing out the spend, this is the order that protects the most value for the least money.
- Tempered glass first. It is the cheapest item and prevents the most common and irritating damage - a scratched or cracked main display.
- A case second. Corners and camera rim protection stop the expensive drops.
- Camera lens glass third. Cheap insurance for a costly camera array.
- A proper PD charger and cable fourth, if the one in the box is underpowered for the battery.
- Wireless pad and power bank last, as convenience upgrades rather than protection.
Spending in that order means that even a modest budget covers the failures that cost the most to repair.
Everyday extras worth considering
Beyond protection and power, a few extras round out the S25 Ultra experience. A quality USB-C to USB-C cable rated for the phone's full wattage is the unsung hero of fast charging, since a weak cable throttles even the best charger. A short cable for travel and a longer one for the bedside covers most situations. If you use wired audio or a DAC, a certified USB-C adapter keeps the connection clean. And a simple microfibre cloth in the bag keeps the screen and camera glass clear, which matters more on a camera-focused phone like the Ultra.

Frequently Asked Questions
Does a screen protector affect the S25 Ultra's S Pen?
A thin, smooth tempered glass protector rated for stylus use has no meaningful effect on S Pen writing and actually protects the screen from nib wear. Avoid thick or textured films, which can dull the writing feel and reduce sensitivity. Always fit glass cut specifically for the S25 Ultra.
Do I need a magnetic case for wireless charging on the S25 Ultra?
You do not need one, because the S25 Ultra supports standard Qi wireless charging with any compatible case or none. A magnetic or Qi2 case simply snaps the charger into perfect alignment for reliable full-speed charging and lets you use magnetic mounts, which many Australian buyers find worth the small extra cost.
What size power bank can I take on a domestic flight in Australia?
Australian carriers allow lithium power banks up to 100Wh in carry-on without special approval, which is roughly 27,000 mAh at 3.7V. Most 10,000 to 20,000 mAh banks are well under that limit, but always check the Wh figure printed on the bank and keep it in your carry-on, never checked luggage.
Is a camera lens protector worth it on the S25 Ultra?
Yes, because the S25 Ultra's rear lenses sit proud of the body and are the first point of contact on a flat surface, and replacing camera glass is expensive. A well-aligned tempered glass lens protector adds a sacrificial layer with negligible effect on photo quality, while a poorly fitted one can cause night-time glare, so buy one cut for the S25 Ultra layout.
Are these accessories covered by warranty in Australia?
Accessories bought from an Australian supplier are held in local stock, priced GST-inclusive and backed by Australian Consumer Law consumer guarantees of acceptable quality and fitness for purpose. That gives you a clear repair, replace or refund path if an item is faulty, unlike an overseas import with no local remedy.
