Sony Xperia Z Ultra phablet: full HD screen and IP58 waterproofing
When the phone in your pocket needs to behave like a tablet, the conversation in any tech circle takes a familiar turn. Big screens were a curiosity in 2012, but by mid-2013 they had graduated into a real product category, and Sony's Xperia Z Ultra landed right in the middle of that storm. Australians who travelled for work between Sydney, Melbourne, and Perth already knew how handy a larger display could be, and the brand behind the Walkman was betting the world agreed.
Announced in June 2013 and reaching shelves shortly after, the Xperia Z Ultra stretched the meaning of phone with a 6.44-inch Full HD panel, a waterproof shell, and the fastest Qualcomm chip of its day. It ran Android in its earliest Jelly Bean form, then picked up KitKat updates that extended its usable life. Anyone flicking through carrier brochures in a Telstra shop on George Street would have spotted it sitting alongside the Samsung Galaxy Note 3, the HTC One Max, and a handful of more cautious handsets.
This phablet earned a reputation as the gadget you bought when you wanted bragging rights at the pub or wanted to read a PDF without squinting through business class. It was never subtle, weighing in at 212 grams and feeling closer to a small tablet than a phone. Those trade-offs were deliberate, aimed at users who wanted their primary device to handle web browsing, video playback, light gaming, and stylus-free note taking without reaching for a tablet or a laptop.
What follows is a closer look at what the Xperia Z Ultra brought to the table, the way it stood up against its rivals, and why it still earns attention from buyers hunting a secondhand bargain through JB Hi-Fi or a private listing on Gumtree. Specifications matter, but so does the feel of the device in daily use, the condition of its battery after years of ownership, and how it pairs with the rugged cases many Aussie tradies prefer.
A giant among phablets and where it fits in 2013
By the middle of 2013 the term "phablet" had moved from trade press jargon into consumer vocabulary, and Samsung's Galaxy Note series had more or less defined the category. Sony's pitch with the Xperia Z Ultra was deliberately different. Where the Note leaned on a stylus and a Super AMOLED panel with saturated colours, the Ultra went the other way, picking an IPS LCD, ditching the pen, and wrapping the whole device in a glass-and-metal frame that carried an IP58 rating. Walk into a Vodafone store in Brisbane and the spec sheets next to the demo units read like a tech lover's wish list from that exact moment.
The comparison matters as much as the marketing pitch, and the table below lines up the Xperia Z Ultra against three flagship phablets of the same generation, helping shoppers weigh their priorities at a glance.
| Feature | Sony Xperia Z Ultra | Samsung Galaxy Note 3 | HTC One Max | LG G Pro 2 |
|---|---|---|---|---|
| Display size | 6.44-inch Full HD | 5.7-inch Full HD | 5.9-inch Full HD | 5.9-inch Full HD |
| Panel type | IPS LCD with TRILUMINOS | Super AMOLED | Super LCD3 | IPS LCD |
| Processor | Snapdragon 800, 2.2 GHz quad-core | Snapdragon 800, 2.3 GHz quad-core | Snapdragon 600, 1.7 GHz quad-core | Snapdragon 800, 2.3 GHz quad-core |
| RAM | 2 GB | 3 GB | 2 GB | 3 GB |
| Storage options | 16 GB, microSD up to 64 GB | 32 or 64 GB, microSD up to 64 GB | 16 or 32 GB, microSD up to 64 GB | 16 or 32 GB, microSD up to 64 GB |
| Rear camera | 8 MP, no flash | 13 MP, LED flash | 4 MP UltraPixel, LED flash | 13 MP, LED flash |
| Battery | 3050 mAh, sealed | 3200 mAh, removable | 3300 mAh, non-removable | 3200 mAh, removable |
| Waterproofing | Yes, IP58 | No | No | No |
| Stylus support | Capacitive tip compatible | Yes, S Pen included | No | No |
| Weight | 212 g | 168 g | 217 g | 172 g |
The numbers do not tell the whole story, but they clarify where Sony chose to spend its engineering budget. Waterproofing, display real estate, and a Snapdragon 800 chip sat at the top of the priority list, while a more modest camera and a slightly smaller battery kept the internals balanced and the chassis manageable in the hand.
Display engineering on a 6.44-inch canvas
The 6.44-inch Full HD panel was the headline feature, and Sony leaned on its TV heritage with TRILUMINOS and X-Reality branding borrowed from the Bravia line. Watching a downloaded movie on the train between Wynyard and Town Hall, the screen's 1920 x 1080 resolution showed its full value, particularly for text-heavy pages where a pixel density of 342 ppi stayed comfortable for extended reading. Colours were not as punchy as the AMOLED panels Samsung and HTC preferred, but accuracy and daylight visibility were noticeably better.
OptiContrast layering and a minimal air gap helped outdoor viewing, which matters for anyone catching a coach along the Coffs Harbour stretch or watching surf reports at Bondi before the lifeguards blow the horn. Touch response was another standout. Sony claimed the panel could track input from pencils, metal pens, and capacitive styli, which made sketching diagrams in a meeting feel surprisingly natural even without a dedicated pen. Apple's iOS coverage on our site addresses the same need with a refined multitouch experience, but few screens at this size could match the Ultra's tolerance for unconventional inputs.
Internal hardware and real-world performance
Beneath the glass sat a Qualcomm Snapdragon 800 clocked at 2.2 GHz, paired with 2 GB of RAM and an Adreno 330 GPU. That combination was standard issue for early 2013 flagships, and the Xperia Z Ultra made the most of it. App switching, web browsing with multiple tabs, and lightweight games such as Modern Combat 4 all ran without stutter, and the thermals stayed sensible thanks to a balanced thermal profile. Push the chip harder with extended Asphalt 8 sessions and the upper rear section warmed up, but never to a worrying degree.
Benchmarks told a familiar story. Quadrant scores clustered around 21,000, Antutu results pushed past 33,000, and Geekbench 3 single-core figures hovered near 900. None of those numbers were chart-topping against the Galaxy Note 3's slightly higher clock, but real-world behaviour felt indistinguishable for everyday tasks. Android 4.2 Jelly Bean shipped out of the box, and Sony was reasonably quick with updates to 4.3 and eventually 4.4 KitKat, extending the device's usable life well into 2015 for anyone who held on to theirs.
Camera system and multimedia expectations
Sony cut the camera back to an 8 MP Exmor RS sensor without a flash, a decision that puzzled reviewers and shoppers alike. The reasoning, according to Sony's product team, was that the waterproof shell could not accommodate a flash without compromising the IP58 seal, but the absence meant low-light photography suffered compared with the Samsung Galaxy S4 and the iPhone 5s of the same year. Daylight shots looked crisp and benefited from Sony's Superior Auto processing, while 1080p video at 30 fps held its own for casual clips of mates at a Saturday arvo barbecue.
Audio was a more pleasant surprise. The mono speaker tucked into the bottom edge produced reasonable volume for spoken podcasts, and Sony bundled a pair of MH1C earphones in the box. Walkman branding still mattered inside Sony's software stack, and the company wrapped Walkman, Album, and Movies apps around the Bravia Engine 2 enhancements on the display to give an integrated feel that competitors rarely matched.
Connectivity, storage, and battery endurance
Dual-band Wi-Fi a/b/g/n/ac, Bluetooth 4.0, NFC, GPS with GLONASS, and LTE on the Australian 1800 and 2600 MHz bands gave the Xperia Z Ultra solid carrier support when paired with Telstra or Optus SIMs. The microSIM slot sat under a sealed flap on the left edge, alongside the microSD slot that accepted up to 64 GB cards. That expansion was useful for anyone loading the device with movies before a long drive from Adelaide into the Barossa Valley or a flight from Tullamarine out to a regional hub.
Storage came in a single 16 GB flavour, of which about 11 GB was user-accessible, making the microSD slot effectively mandatory. The 3050 mAh sealed battery delivered a full working day for moderate users, and stretched close to a day and a half with Wi-Fi calling disabled and screen brightness dialled back. Heavy users streaming video over 4G on a commute from Hornsby toward the Sydney CBD saw closer to twelve hours, which was respectable for a 6.44-inch device but not class-leading for that generation.
Comparing the Xperia Z Ultra to its strongest rivals
Against the Samsung Galaxy Note 3, the Ultra offered a larger screen and the waterproofing advantage, but lost on RAM, camera resolution, and the productivity gains of the S Pen. Against the HTC One Max, Sony's choice of a faster Snapdragon 800 chip rather than the slower Snapdragon 600 made the Ultra feel snappier, even though HTC's BoomSound speakers gave the One Max a clear win for bedroom music playback. Against the LG G Pro 2, the choice boiled down to software preferences, with LG's lighter skin feeling closer to stock Android and Sony's Xperia UI offering a more polished aesthetic with its own Walkman and Album apps.
Anyone cross-shopping from the iPhone direction will find a more relevant head-to-head in the broader smartphone reviews section, where the Xperia Z Ultra sits alongside other Android rivals of the same generation. Phablet users who preferred iOS were still waiting for Apple to formalise the category, and it would be another year before the iPhone 6 Plus arrived to contest the space Sony had entered first.
Buying considerations and where the Xperia Z Ultra sits now
Picking up a used Xperia Z Ultra today means accepting compromises. The battery is the first casualty, with most units sold secondhand needing a replacement cell to match original endurance. Waterproof seals also degrade over time, so a device rated IP58 in 2013 may not survive an accidental dip in a hotel pool. Cases are scarce, but third-party options from local chains such as JB Hi-Fi and online marketplaces cover the most common drops and scratches.
Pricing varies widely. Indian listings through stockists sat around ₹39,000 at launch, while Australian buyers importing grey-market units paid closer to AUD 749 to AUD 899 depending on warranty status. Modern condition-focused buyers pay between AUD 150 and AUD 300 on the second-hand market today, with prices climbing for boxed units and unused accessories.
For readers chasing the same combination of large screen and rugged build in a more contemporary package, the phablet category has only grown, with most flagship manufacturers now offering 6.7-inch or larger options that pair slimmer bezels with the same ultra-waterproof philosophy. The Sony Xperia Z Ultra paved that road back when the term phablet still raised eyebrows, and its DNA lives on in the Xperia 1 line and in competing handsets from Samsung, Oppo, and Xiaomi that land on Australian shelves every season.
