Galaxy S26 Latest Leaks: Release Date, and Comparison with S25 and S24

The Galaxy S26 series is attracting attention as Samsung's flagship model for 2026. While expectations are high for the latest smartphone, which brings together the best of Samsung's technology, many people are likely concerned that "the latest model might be too expensive to afford" due to recent price increases and the depreciation of the yen. For working professionals in their 20s and 30s, in particular, a smartphone is an indispensable tool for daily life and work, yet spending over 150,000 to 200,000 yen is a significant amount that requires careful consideration.

This article will organize the latest leaked information and predicted specifications for the Galaxy S26, while also explaining the overwhelming cost performance that can be gained by daring to choose a "previous generation model" or a "used smartphone."

Latest Galaxy S26 Leaks and Predicted Specifications

The Galaxy S26 series is expected to be a legitimate evolution of its predecessor, the S25 series. According to leaked information, the biggest changes will be "further integration of AI features" and "improved power efficiency."

It is said that hardware evolution in recent smartphones is reaching its peak, but Samsung is focusing on improving the user experience with its proprietary AI, "Galaxy AI," at its core. The S26 is expected to be equipped with Qualcomm's next-generation chipset, the Snapdragon 8 Gen 5 (tentative name), which is anticipated to enable smoother complex image editing, real-time translation, and even advanced task management.

Furthermore, there are rumors that the design of the camera area, which has remained largely unchanged for several years, will be revamped. It may evolve into a more refined flat exterior or a body with exquisite curves that fit comfortably in the hand.

Release Date Likely February 2026? Forecast Based on Past Trends

Samsung's flagship Galaxy S series typically makes its debut at the "Galaxy Unpacked" new product announcement event, which is held annually in January or February.

Looking back at recent schedules, the Galaxy S24 was announced in January 2024, and the S25 in January (or February) 2025. Therefore, it is highly likely that the Galaxy S26 will be announced from late January to early February 2026, with sales in Japan starting from mid-February to March.

In Japan, in addition to sales through major carriers such as Docomo, au, and SoftBank, simultaneous release of SIM-free versions on the Samsung official website has become a regular occurrence in recent years. For those who want to get their hands on the latest model as soon as possible, this February to March timeframe is the biggest opportunity.

However, it is not uncommon for pre-orders to flood in immediately after release, causing delays in delivery. Also, discounts are rarely expected immediately after release, so purchasing at the regular price is standard.

Evolving AI Features and Hardware Performance

The chipset at the heart of the Galaxy S26 is expected to be the latest Snapdragon, using a 3nm or 2nm process. This will not only improve processing power but also significantly enhance power efficiency, reducing battery consumption.

Furthermore, Galaxy AI will also evolve. In addition to conventional text translation and summarization features, there are rumors of advanced video editing functions that allow users to freely move and erase specific objects within videos captured by the camera, as well as personalized assistant functions tailored to individual lifestyles.

Regarding memory (RAM) capacity, to handle the load of AI processing, it is suggested that 12GB or more will be standard for the regular model, and 16GB for the Ultra model.

Prepare for Price Hikes! S26 Price Predictions and Strategic Purchasing Methods

One issue that cannot be avoided when considering the Galaxy S26 is "price." While the global semiconductor shortage is easing, the soaring cost of raw materials, increasing logistics costs, and especially the impact of the depreciating yen in Japan are serious concerns.

Looking at past trends, the price of flagship smartphones has been steadily increasing by 10,000 to 20,000 yen annually. Even the standard model of the Galaxy S26 is expected to be around 150,000 yen, and the top-end Ultra model could easily exceed 200,000 yen.

For working professionals in their 20s and 30s, paying 200,000 yen at once is a big decision. Of course, there are options like carrier installment programs (residual value setting), but many people may dislike the total amount of payment or the constraint of having to return the device after a few years.

Therefore, it's worth considering the option of "smartly buying a discounted high-performance model used" when a new model is released. The Galaxy S series is highly durable, and even models from two to three years ago possess performance that outperforms current mid-range smartphones. If you don't insist on the latest S26, you can build a satisfactory environment with less than half the budget.

Is it heading towards over 150,000 yen? Price trend predictions.

Looking back at the domestic prices of past Galaxy S series (SIM-free/carrier reference), prices have steadily risen with the S23, S24, and S25. In particular, the cost of incorporating the latest AI technology and high-performance sensors directly translates into the selling price.

In the case of the Galaxy S26, it is not impossible for the starting price to be around 148,000 yen (tax included) for the minimum configuration, and reach 220,000 to 250,000 yen for models with larger storage capacity or the Ultra model.

With such increasing prices, many users are starting to question, "Will we really feel the difference in evolution for that extra cost?" For example, if the performance difference between the S25 and S26 is a 20% improvement, but the price difference is 50,000 yen, some might argue that it's better to use that 50,000 yen to buy another tablet or peripheral device to improve their daily convenience.

For cost-conscious users, the announcement of a new model should be seen not as "a signal to buy the latest model," but as "a signal for when older models will become cheaper."

Who Should Wait for the Latest Model and Who Should Choose Used/Previous-Generation Models

So, who should wait for the Galaxy S26? The answer is clear: those who "want to be the first to master the latest AI features," "want to engage in creative activities with the best camera performance," or "prioritize technological curiosity over budget." On the other hand, those who fall into the following categories can improve their quality of life by intentionally choosing a used or previous-generation model (S24 or S25).

  • Sufficient practical specifications (smooth operation) are enough

  • Want to save money on smartphone costs and spend it on hobbies or self-improvement

  • Worried about used items but want to get them cheaply if there's a solid warranty

  • Considering having two phones (for work and personal use) and want to keep the cost per phone low

In particular, used devices handled by PRODIG are inspected by professional staff, minimizing the anxiety inherent in used products. Even without waiting for the S26's release, by acquiring a highly polished S24 series or similar, you can immediately start a comfortable smartphone life.

Historical Model Comparison: Differences Between S26, S25, S24, and S23

When considering purchasing a Galaxy series, it is important to correctly understand the specification differences between the latest S26 and the currently available S25, S24, and S23. The table below summarizes the differences in key items.

Item Galaxy S26 (Predicted) Galaxy S25 Galaxy S24 Galaxy S23
Chipset Snapdragon 8 Gen 5 Snapdragon 8 Gen 4 Snapdragon 8 Gen 3 Snapdragon 8 Gen 2
Memory (RAM) 12GB〜16GB 12GB 8GB〜12GB 8GB
AI Features Advanced Generative AI Integration 2nd Gen Galaxy AI 1st Gen Galaxy AI Partial support via update
Camera 200-megapixel sensor refresh? 50-megapixel〜 50-megapixel〜 50-megapixel〜
Price (used estimate) 150,000 yen〜 (new) 100,000 yen〜120,000 yen 70,000 yen〜90,000 yen 50,000 yen〜60,000 yen

 

Comparing them in this way, it's clear that the S23 to S24 saw a major turning point with the full-scale implementation of AI features. Conversely, this means that models from the S24 onwards can offer a user experience that is quite close to the latest S26.

Galaxy S24/S25: Best Balance of Practicality and Cost-Effectiveness

The Galaxy S24 and S25 boast top-class perfection among current Android smartphones. Especially from the S24, the bezels have become extremely thin, realizing a large screen while maintaining a compact size.

Equipped with the Snapdragon 8 Gen 3, the S24 can handle demanding 3D games and video editing with ease, and possesses performance that allows it to remain a front-runner as a main device for several years to come.

When the latest S26 is released, the used prices of these S24 and S25 models will drop even further. By abandoning the insistence on "must be new" and considering A-grade or B-grade used products, you can save tens of thousands of yen, which can then be used to purchase wireless earphones or a smartwatch.

Galaxy S23: The Best Cost-Effective Second Phone

If you are looking for a "secondary phone for work" or a "second phone solely for video viewing," the Galaxy S23 is currently the most cost-effective option. Although some time has passed since its release, the Snapdragon 8 Gen 2 is highly regarded as a very efficient chip with suppressed heat generation. Furthermore, OS updates are continuously provided, so you can use it with peace of mind in terms of security.

In the used market, it can be found for as low as 50,000 yen, and you will likely get much higher satisfaction than buying a new mid-range phone. It is recommended not only as a secondary phone but also for minimalist users in their 20s who want to keep their main phone costs down. The advantage of used smartphones is that you can experience such "former flagships" at an affordable price.

Frequently Asked Questions

We've compiled common questions many people have when considering a used smartphone. Please use this as a final check before purchasing.

Can I check the battery status?

PRODIG thoroughly checks the battery capacity, which is the biggest concern with used smartphones, during inspection. For units with significant deterioration, we either clearly state this beforehand or remove them from sales. For Galaxy devices, you can check the battery health (percentage) from the settings screen. If you have concerns, please inquire with store staff or refer to the rank description in the product details. Generally, if the capacity is 80% or more, you will not experience much stress in daily use.

Furthermore, if there is a clear abnormality in the battery (such as sudden shutdowns) immediately after purchase, we will respond diligently within the warranty period. We do not sell items that are unusable simply because they are used.

How long is the support period (OS updates)?

Samsung has significantly extended the OS update support period for its flagship models in recent years. For Galaxy S24 and later models, Samsung has announced that it will provide up to seven years of security and OS updates. This means that even if you purchase a used S24, you can continue to use it in the latest secure environment until around 2030.

While used Android smartphones from a while ago had a reputation for having a "short lifespan," the current Galaxy S series has a very long life, and once you acquire one, it will serve as a reliable companion for a long time. This long support period is one of the major reasons why we can confidently recommend used Galaxy devices.

Summary: Use the arrival of the Galaxy S26 as an opportunity to find the perfect device for you.

The Galaxy S26 will undoubtedly be the masterpiece smartphone of 2026. However, "latest" doesn't always mean "best" for all users. In an era of rising prices, the perspective of how to acquire a satisfying gadget within a limited budget is sought after by smart individuals in their 20s and 30s.

"Pre-order the latest S26 and embrace the future."

"Aim for a discounted S25 after the new model's announcement."

"Get a used S24 or S23 from PRODIG for ultimate cost performance."

All these choices are valid. What's important is to choose a device that you are happy with, based on your own needs and budget. If you have reservations about used smartphones, please visit the PRODIG store in Akihabara or browse our extensive online inventory. Our professionally selected devices, backed by comprehensive warranties, are sure to make your daily life more convenient and enriched.
