[2025 Latest] The Best Used "Big Smartphones" to Choose From! A Comprehensive Guide to the Pros, Cons, and Recommended Models of Large Screen Smartphones
Are you considering replacing your smartphone and struggling with the soaring prices of new devices? Especially for models with large screen sizes, it's not uncommon for the latest models to significantly exceed 100,000 yen.
"I want to enjoy videos and games on a larger screen, but new ones are too expensive to afford..." "I'm worried that a big smartphone might be inconvenient to carry around, and what about the battery life...?"
Many people might be facing such concerns. Therefore, for those searching for "used large smartphone," this article thoroughly explains everything from the appeal of large-screen smartphones available used, to points to consider when choosing one, and even recommended models. This article aims to alleviate anxieties about used smartphones from three perspectives – "peace of mind, affordability, and practicality" – and support you in making a smart smartphone choice.
Pros and Cons of Choosing a "Large Smartphone" Secondhand

The trend towards larger smartphone screens offers significant advantages to many users. However, there are also some disadvantages, making it important to understand them thoroughly before purchasing. Especially with used smartphones, consideration from a different perspective than new ones is necessary. When considering a large-screen smartphone, it is crucial to compare these pros and cons to make the most suitable choice for your lifestyle. For example, if you frequently enjoy video content or games for extended periods, you will likely maximize the benefits of a large screen. Conversely, if you frequently operate your phone with one hand on trains or prioritize portability, you need to consider the disadvantages. Furthermore, it's worth noting the practical advantage that larger models tend to have larger battery capacities, allowing for longer usage depending on how they are used. Balancing the affordability unique to used smartphones with the convenience of a large screen, and finding the optimal balance for you, is key to a satisfactory smartphone choice. Additionally, large-screen smartphones are recommended for seniors or those concerned about their eyesight, as text and images are easier to see. They might also make great gifts for family members. Thus, large-screen smartphones have the potential to enrich our lives in various ways, not just by having a bigger screen.
What Can You Do with a Large Screen? Explaining the Benefits
The greatest advantage of a large-screen smartphone is, without a doubt, the immersive visual experience it offers. Especially for video viewing and gaming, the difference is striking. Fine details that might be missed on a smaller screen are vividly displayed on a large screen. For example, the sense of presence in movies and dramas, and the immersion in game worlds, will be significantly enhanced. When reading e-books, the larger, easier-to-read text can help reduce eye strain. Furthermore, when browsing websites and using social media, the increased amount of information displayed at once reduces the need for scrolling, making for a more comfortable browsing experience. Large screens are also highly advantageous for multitasking. You can split the screen to watch a video on one half while operating a messaging app on the other, enabling efficient work. For those who use their phone for work, spreadsheet software and document editing can be done more smoothly, perhaps even feeling closer to using a PC. In this way, large-screen smartphones enrich our digital lives in a wide range of situations, from entertainment to practical uses.
Is it inconvenient to carry? Disadvantages of large smartphones
The first disadvantage of large-screen smartphones is their size and weight. Because the screen size is large, the device itself is also large, which can make it difficult to fit into pockets or small bags. You may need to always hold it in your hand or carry it in a larger bag, which can be inconvenient for portability. This is especially true for women, as it often won't fit into small handbags, which can be a major deterrent to purchase. Also, the weight tends to increase, so holding it with one hand for a long time can cause arm fatigue. Furthermore, the difficulty of one-handed operation is also a disadvantage. It can be hard to reach the edges of the screen with your finger, making two-handed operation the norm, which can be inconvenient when you want to quickly operate it with one hand. The risk of dropping it also increases, requiring more careful handling. However, these disadvantages can be mitigated by using cases and accessories. For example, a phone case with a ring can assist with one-handed operation, and a case with a strap can prevent drops. By understanding the disadvantages and taking your own countermeasures, you can maximize the benefits of a large-screen smartphone.
Key Points to Absolutely Check When Choosing a Large-Screen Smartphone

When choosing a large-screen smartphone secondhand, it's crucial to assess various specifications holistically, not just focus on the screen size. Especially with used items, unlike new ones, there's a wide range of items to check, such as battery condition and scratches/dirt. By thoroughly covering these points, you can achieve a satisfying smartphone choice without regrets. The performance of a large-screen smartphone varies widely, including display resolution, CPU performance, camera functions, and battery life. Whether these elements are well-balanced affects the comfortable user experience. It's also important to clarify which specifications you prioritize most according to your own usage. For example, if you primarily enjoy games, prioritize CPU and GPU performance; if video viewing is central, prioritize display quality and battery capacity – a purpose-driven selection is required. For used smartphones, in addition to these specifications, the condition of the device is also a very important check point. Choosing a reliable shop is also essential for a secure purchase. At PRODIG, our expert staff carefully inspect each device and clearly state its condition, so you can purchase used smartphones with confidence.
Display Size and Resolution
The display, which is the biggest appeal of a large-screen smartphone, is crucial not only in terms of size but also resolution. Resolution refers to the density of pixels displayed on the screen; the higher the number, the more detailed and beautiful the images you can enjoy. For example, there are various resolutions such as Full HD (1920x1080) and QHD (2560x1440). With a large screen, low resolution can make the image quality appear rough, so we recommend choosing a model with as high a resolution as possible. Especially if you frequently enjoy video streaming services or high-definition games, choosing a high-resolution model will maximize its appeal. Also, the type of display is a point to check. Organic EL (OLED) displays are characterized by more vibrant colors and deeper blacks compared to LCD displays. On the other hand, LCD displays tend to consume less power, making them suitable for long-term use. When choosing a used smartphone, it's important to consider these points and find a model equipped with the display that best suits your usage. At PRODIG, you can check the display specifications on each product's detailed page, allowing you to carefully consider before purchasing.
Battery Capacity and Duration
Large-screen smartphones consume a lot of power to drive their large displays. Therefore, if a model has a small battery capacity, it will need to be charged frequently, which would negate the benefits of a large screen. When buying a used smartphone, you also need to consider battery degradation, so special attention is required. It's reassuring if you can check how much the battery capacity has decreased from its new state (maximum capacity). For iPhones, you can check the battery health from the "Settings" app, so it's good if you can confirm this before purchasing a used device. At PRODIG, we clearly state the battery condition, so you can purchase with confidence. Also, not just battery capacity, but power-saving performance is also important. The latest CPUs have improved power-saving performance, and combined with a large-capacity battery, they enable long hours of use. If you want to use a large-screen smartphone for a long time, we recommend choosing a newer model or one with a larger battery capacity. You can also use a spare battery or a mobile battery for added peace of mind.
CPU/GPU Performance
The CPU and GPU, which determine the performance of a large-screen smartphone, are crucial components directly linked to a comfortable user experience. The CPU (Central Processing Unit) is like the brain of the smartphone, handling various processes. The GPU (Graphics Processing Unit) specializes in processing images and videos, and its performance significantly impacts gaming. If you want to enjoy high-quality games and videos on a large screen, choosing a model equipped with a high-performance CPU and GPU is essential. With used smartphones, many slightly older models still have sufficiently high-performance CPUs, allowing you to acquire them at a better price than new ones. For example, with iPhones, Pro series and Plus series tend to have higher-performance CPUs than standard models. For Android smartphones, it's good to choose models equipped with high-performance chips like high-end Snapdragon models or Google's proprietary Tensor chip. Before purchasing, we recommend referring to benchmark scores and actual reviews to choose a model with performance that suits your usage.
Camera Performance
Large-screen smartphones have the advantage of allowing you to view photos and videos on a large screen immediately after shooting. Many models are equipped with image stabilization and high-quality sensors, making it easy to shoot beautiful photos and videos. Especially high-end models such as the Pro and Ultra series feature multiple cameras, allowing you to shoot at various focal lengths such as wide-angle, ultra-wide-angle, and telephoto. Advanced shooting functions such as night mode and portrait mode are also abundant, making it possible to shoot high-quality photos comparable to an SLR camera with just a smartphone. When choosing a used smartphone, check not only the camera's megapixel count but also the sensor size, aperture value (F-number), and optical zoom magnification. Generally, higher values in these specifications tend to result in higher quality photos. Also, for used items, it is an important point to check if there are any scratches on the lens. PRODIG provides detailed product condition descriptions from Rank S to Rank C, allowing you to check camera performance with peace of mind.
Portability and Weight
For large-screen smartphones, portability and weight are also important check points. Generally, models with screen sizes exceeding 6.5 inches tend to be difficult to operate with one hand and hard to fit into pockets. However, recently, models have increased that keep the screen size while reducing the body size by narrowing the display bezels to the extreme. Also, weight varies depending on the material. For example, models using lightweight materials such as titanium or aluminum alloy are relatively light even with a large screen. On the other hand, models using glass or stainless steel have a luxurious feel, but tend to be heavier. If you carry a large-screen smartphone daily or use it in your hand for long periods, it is important to choose a model considering these points.
Unique Considerations for Used Products
When choosing a used smartphone, the most important thing is to thoroughly check the product's condition. In particular, display scratches, body dents, and battery degradation are crucial points directly affecting comfortable use. PRODIG carefully ranks product conditions into four levels, from S to C, and presents them on the product detail page.
-
S Rank: Unopened, brand new item.
-
A Rank: Very good condition. Very minor scratches or signs of use, but generally clean.
-
B Rank: Good condition. General wear and tear, small dents visible from normal use, but no issues with operation.
-
C Rank: Fair condition. Noticeable scratches or paint peeling, but no impact on functionality.
By clearly defining the product condition in this way, customers can make informed choices before purchasing. Furthermore, always confirm the presence of network usage restrictions and whether SIM lock is unlocked before purchasing.
