Tecno's Phantom Ultimate G Fold tri-foldable concept folds inwards to protect the display
The Tecno Phantom Ultimate G Fold concept folds inwards, which keeps the vulnerable 9.94' main display completely inside the phone's body when folded. This is similar to the horizontal bi-folds of today and features a cover display that is used when the phone is folded. The Phantom Ultimate G Fold tri-fold concept has a huge 9.94' display inside
The old Phantom Ultimate 2 concept was more like the Huawei Mate XT Ultimate – it only had one display and folded in such a way that left one third of it exposed in lieu of a cover display.
The Phantom Ultimate G Fold concept changes that. It has a small hinge that forms a small teardrop shape as it folds the right third of the display. Then a larger hinge folds over that and a self-locking mechanism keeps the device closed. The Phantom Ultimate G Fold uses two sizes of hinges
The result is an impressively thin phone when folded, just 11.49mm. Unfolding it drops the thickness to just 3.49mm. For comparison, Huawei's tri-fold phone (which is a production model, to be fair, not just a prototype) is 12.8mm folded and 3.6-4.8mm unfolded (different segments have different thicknesses).
The extra cover display does add a bit of thickness – the Phantom Ultimate 2 concept was 11mm – but that is a small price to pay for a more durable device. The Phantom Ultimate G Fold is only 3.49mm thick when unfolded
The G Fold has a battery capacity of 'over 5,000mAh', which is quite impressive, given how thin the individual segments are. We'd like to see an exact number, though, as Huawei managed to go up to 5,600mAh.
The triple camera (lens and sensor details TBA) lives on the middle third of the Tecno Phantom Ultimate G Fold – that puts it on the back of the device when folded. The hinges can be held at various angles, which allows you to aim the camera as if it were on a tripod.
Tecno utilized ultra-high-strength steel (2,000MPa) and a thin-but-strong Titan Fiber plate (measuring just 0.3mm) for the back cover to make this design possible.

Some details are kept under wraps for now, like the size of the cover display, the weight of the phone and so on. The chipset is described as 'high-performance', but we don't even know its brand.
Not that it matters all that much – again, the Phantom Ultimate G Fold is just a concept device. If you want to see it in person, Tecno will bring it to its booth at MWC 2026. The company is sure to bring more phones (foldable and otherwise) to the congress too - like, say, the sequels to the Phantom V Flip and V Fold.

Slim phones with 10,000 mAh batteries are possible, but may be a bad idea
If there's one shared grievance among all smartphone users, it would likely be something related to the battery. Regardless of the brand you use, chances are you'd like your phone to have a bigger, longer-lasting, and faster-charging battery. That's true for me, my friends and family, and the vast majority of people who take the time to answer our polls and participate in our discussions. Given all that, it's no surprise that whenever a smartphone with a giant battery makes the news, people get at least intrigued, if not outright excited. That's also the reason the recent rumor of a phone the size of a Galaxy S25 Ultra, but with a 10,000 mAh battery, may sound like a dream coming true. I hate being a killjoy, but if something sounds too good to be true, it usually is for a reason. I won't say that silicon batteries are a scam, but there's definitely a catch, which is why some of the biggest smartphone companies in the world avoid them. Recently, we've seen a few Chinese manufacturers adopting silicon-carbon batteries with much higher capacities than traditional cells. Among the latest examples are the Honor X70 and Oppo K13, featuring 8,300 mAh and 7,000 mAh batteries, numbers are possible thanks to the updated technology of the lithium-ion batteries. In silicon-carbon batteries, the graphite anode is infused with silicone, allowing it to store more energy in the same space. In theory, the difference can reach ten times, which makes silicon batteries have a much higher energy density. The Honor X70 has an 8,300 mAh battery | Image credit — Honor Simply put, you get much higher capacity for a battery of the same size, which allows slim phones and foldables to have better batteries. That's the reason the Honor Magic V and Oppo Find N5 have larger batteries, despite being thinner than the Galaxy S25 Ultra . However, that achievement comes with its own problems, which are the likely reason we won't be seeing more of those batteries anytime soon. You might have heard that there are limitations for flying with lithium-ion batteries. While the whole battery shouldn't exceed 100 Wh, there's also a 20 Wh limitation for each individual cell. If a battery exceeds that limit, it has to be treated as a dangerous good, and it wouldn't be easily allowed on airplanes. Unlike the US regulators, we usually measure the capacity of smartphone batteries in mAh. That can easily be converted to Wh, and @UniverseIce has recently done the math for some of the most popular smartphones. Here are their capacities in Wh and mAh: You might wonder how the OnePlus 13 manages to pack a 6,000 mAh battery and pass regulatory checks. After all, its capacity puts it above the 20 Wh limit. The answer is simple and obvious in the notes on the official OnePlus 13 specs page – it adopts a dual-cell design, so each individual cell has a capacity of 3,000 multi-cell design is also the reason you can carry your laptops and tablets on airplanes without labeling them 'dangerous goods.' But that's not the only challenge with silicon-carbon batteries. Even if the major manufacturers follow OnePlus' example and decide to go the multi-cell way, that won't solve all issues. One of the greatest challenges that pure silicon batteries face is extreme expansion. When completely charged, the structure of a fully silicon battery can swell up to 300%, which would put mechanical stress on the battery and affect its functioning. I mean, have you ever seen a swollen battery and not worried? I haven't! Manufacturers limit the expansion by using a silicon-carbon composite instead of pure silicon. Adding carbon helps the structural integrity, reduces swelling, and helps with other issues. For example, the low electrical conductivity of silicon can slow down charging and lead to the production of more heat, but carbon reduces these effects. Phones with best battery life in 2025: Independent test results Essentially, the more silicon in a battery, the bigger its capacity, but the lower the longevity. The good news is that companies are working on ways to solve those issues and improve our phones' batteries. The bad news is that it'll probably take a while before we can see the results on our smartphones.I'm all in for a battery tech breakthrough that would make my phone last forever, but that's only part of the equation. More efficient chipsets and improved energy management have already boosted battery life. The next step might simply be using current tech in smarter it's all about making a choice. On the one hand are big batteries, which may not retain much of their capacity for more than a couple of years, but will last longer during that time. On the other hand are the smaller batteries, that might need a charge more often, but will likely keep their capacity for all 7 years of software updates we get with modern choice Apple, Samsung, and Google appear to be making is a combination of safety and longevity, while some Chinese brands opt for flashy specs. I am with the giants in that regard, but I like that we finally have a different choice. Switch to Total Wireless and buy 2 months of a 5G Unlimited plan to score the phone free!

This is why your experience with the Galaxy S26 Ultra could be so much different than mine
Qualcomm's new flagship application processor (AP), the Snapdragon 8 Elite Gen 2, is expected to power the top-of-the-line Galaxy S26 Ultra when the phone is released in late January or early February next year. However, a fresh rumor reveals that two Galaxy S26 Ultra owners could have differing experiences with their phones depending on the foundry that produced the Snapdragon 8 Elite Gen 2 application processor (AP) powering their units. It's a strange situation to think that the Galaxy S26 Ultra in my hand could run faster than the one in yours, and deliver better battery life even though the AP that both are using is the same. Without trying to sound repetitive, the difference would be in the foundry that manufactured the two chipsets and the process node employed by each. In plain English, Qualcomm is rumored to be using "dual-sourcing" for the Snapdragon 8 Elite Gen 2, which means that some APs will be made by TSMC and some by Samsung Foundry. As of this moment, Qualcomm will dual-source the Snapdragon 8 Elite Gen 2 AP. | Image credit-Weibo Posting on Chinese social media site Weibo, tipster Digital Chat Station says that the Samsung-built version of the Snapdragon 8 Elite Gen 2 AP has not yet been cancelled. If true, at this moment, we are looking at two different variants of the chip. TSMC will build the chipset using its third-generation 3nm process node which is the same process TSMC will use to build the A19 APs for the upcoming iPhone 17 series. Samsung Foundry, on the other hand, will use its 2nm Gate-All-Around (GAA) process node, which in theory would be technologically superior to TSMC's 3nm version of the chipset. That's because as the process node number drops, so does the size of the transistors employed. Smaller transistors mean an increase in transistor density, which typically measures the number of transistors in a die per square millimeter. This means that a chip carries more transistors in a given area. The transistor density figure is important because as that number rises, it usually means that a foundry can pack more transistors into a given space, which means that smaller transistors are being used. Smaller transistors use less power, switch states more quickly, and reduce the manufacturing cost per function. Samsung Foundry also has another advantage as its 2nm process node includes the use of GAA transistor architecture which results in the gate surrounding the channel on all four sides. This reduces current leaks and improves the drive current, which results in better-performing APs that use less power. The pricing of the Snapdragon 8 Elite Gen 2 is rumored not to be much higher than the price of the Snapdragon 8 Elite. Part of that is due to Qualcomm's use of its 3nm process (albeit its third-generation version), and Samsung Foundry's involvement. This could be a big deal for the latter, which has a market share in the industry of only 7.7% compared to TSMC's 67.6% (both figures are Q1 2025 numbers). Also, it would be a positive sign that Samsung Foundry has been able to improve its awful yield figures and was able to hit its goal of 50%. Whatever happens with the Snapdragon 8 Elite Gen 2, there is speculation that Qualcomm will copy Apple next year and offer two different versions of the Snapdragon 8 Elite Gen 3. With a much higher price expected to be charged by TSMC for its 2nm wafers, a pricier, more cutting-edge version of the Snapdragon 8 Elite Gen 3 made by TSMC could be used in more premium versions of Samsung's flagship Galaxy S27 series in 2027. The non-premium version of the AP would be made by Samsung Foundry using its 2nm process and would have lower CPU and GPU clock speeds and reduced cache. Samsung Foundry's Snapdragon 8 Elite Gen 2 is rumored to have a model number of SM8850s and have the codename 'Kaanapali S'. The Snapdragon 8 Elite Gen 3 "Pro" could have a model number of SM8950, with the "non-Pro" model carrying a number of SM8945. Will Qualcomm dual-source the Snapdragon 8 Elite Gen 2? As soon as we have an update, we will let you know.

Samsung's next Galaxy phones could bring more AI choices, in addition to Google's Gemini
Referential image of the Samsung Galaxy S25 Ultra. | Image credit — PhoneArena Samsung is planning to bring more AI options to its upcoming Galaxy phones. Right now, the company uses Google's Gemini AI on devices like the Galaxy S25 and Z Fold devices, but that might change soon. According to a new report from Bloomberg, Samsung is talking to other AI companies — including OpenAI and Perplexity AI — about working together on future Won-Joon, who runs Samsung's mobile division, told Bloomberg that the company is in talks with several AI providers. His goal is to offer Galaxy users more choices. He explained that Samsung is open to using any AI agent, as long as it offers a strong experience. Samsung already uses Gemini for many features on its Galaxy devices, like Circle to Search and AI-powered editing tools. But as reported back in June, the company has been exploring ways to rely less on Google. That includes looking at outside partners like Perplexity AI, a company that blends AI chat answers with real-time web results. Samsung is reportedly close to investing in Perplexity, which could lead to deeper integration in upcoming Galaxy models. Samsung Galaxy Z Fold 7. | Image credit — PhoneArena The Galaxy S26 is expected early next year and could be the first to showcase this expanded AI strategy. Samsung may also be considering OpenAI — the company behind ChatGPT — as another possible partner. This would be a big move and would follow Apple's recent decision to let users choose between AI providers like ChatGPT and Gemini on iPhones. Beyond software, Samsung is also reviewing its hardware plans. The Galaxy S26 may feature either Qualcomm's next Snapdragon processor or the company's own Exynos 2600 chip. Samsung often uses both, depending on region and model. For example, its flagships might use only Snapdragon chips, while other models used a mix of the two. By working with multiple AI companies, Samsung hopes to offer a more flexible experience for users. It's part of a larger trend across the tech industry, where companies want to give people more control over which AI tools they use. That approach could make Samsung phones more appealing to people who want AI to feel more personal or transparent. Still, the challenge will be figuring out how these different AI systems work together on the same phone. Whether it's Google, OpenAI, or Perplexity, Samsung will need to make sure the overall experience stays smooth and easy to use.
