When most people buy a new smartphone, they often focus on features like the camera, screen, or the latest AI functions. However, in recent years, there has been a trend resembling a “arms race” where smartphone storage capacity continues to soar, with some reaching as high as 1TB. Many people struggle to determine how much storage space their phone actually needs.
The idea of having a large storage capacity may sound appealing, leading many to opt for flagship models, but they come with a higher price tag. Do you really need that much space? The answer is likely a no.
Apart from applications (APPS), videos are perhaps the biggest storage hog. Thanks to convenient cloud storage services, freeing up space on your phone has become easier than ever before. Unless you download a large number of hefty applications and prefer to store videos locally rather than in the cloud, you may actually need less storage space than you think.
Below are various analyses of smartphone storage capacities compiled by the global business technology and IT news website ZDNET, along with how to choose a phone’s capacity based on the user’s actual needs.
The minimum storage configuration for smartphones in 2026 is 64GB. Most manufacturers stopped producing phones with only 64GB of storage space years ago. Currently, only a few ultra-low-end models remain on the market, such as the Motorola Moto G Play and BLU View 5. At this capacity level, you can only install a handful of applications.
Who needs 64GB of smartphone storage space? Users who primarily use their phones as simple communication tools (for calls and texts) and do not install many applications or take a lot of photos and videos.
Most modern smartphones start with 128GB of storage. Although this capacity may seem modest, it is sufficient for many people, perhaps even the majority. It can accommodate around 100 or more daily apps, thousands of photos, and some videos. While you may encounter storage space issues in a year or two, you can typically resolve it by deleting old content.
Who needs 128GB of smartphone storage space? This is suitable for those who download daily apps, take a lot of photos, prefer streaming media online rather than downloading content, are comfortable with using cloud storage, don’t mind deleting old files, or frequently change devices.
This is the “sweet spot” configuration for most new smartphones today. 256GB of space allows you to shoot a large number of videos and photos, download hundreds of apps (including high-quality, space-consuming games), regularly update the system, and almost never worry about running out of storage space.
It can keep you going for a long time without needing to clean up apps or files. For most people, this capacity is more than enough.
Who needs 256GB of smartphone storage space? This is suitable for those who want to use their phone without ever considering storage issues or intend to use the phone for a long time (four years or longer) and do not want to rely on cloud storage.
This is a configuration tailored for specific needs. If you opt for 512GB, you need to have a clear reason, such as video editing, heavy-duty gaming, or needing to store a large amount of offline media content.
A phone with this capacity has essentially become a portable hard drive, capable of storing tens of thousands of photos, a massive music library, years’ worth of work documents, or hours of video.
Who needs 512GB of smartphone storage space? Those who use their phones for professional work, need to store large amounts of offline content, or plan to use the same phone for five years or longer.
Only high-end models from Google, Samsung, and Apple offer a 1TB storage option, usually limited to the highest configuration versions. In reality, very few people require this much space because it is already comparable to desktop storage capacity. For a phone, this is considered a massive amount of storage, enough to hold tens of thousands of photos, hundreds of hours of videos, and hundreds of applications.
Who needs 1TB of smartphone storage space? Those who shoot hours of 4K videos for content creation, individuals who do not use cloud storage services, store a vast amount of offline content, or plan to use the phone for an extended period.
When purchasing a phone, regardless of the labeled storage capacity on the box, the actual available space will be slightly less. This is because some space is reserved for the phone’s operating system (typically 20GB to 30GB), pre-installed applications, on-device AI systems, and so on. Therefore, when estimating the required storage space, be sure to deduct this reserved space first. Additionally, consider the following factors:
Operating systems are getting increasingly larger each year. If you plan to use the same phone for three years or longer, you may find that the proportion of available space occupied by the operating system significantly increases. Choosing a larger storage capacity when planning to use the phone long-term can help accommodate future needs.
Videos consume a lot of storage space, especially high-quality ones. The space taken up by a single video can be equivalent to hundreds or even thousands of photos. If you take more photos than videos (or store all videos in the cloud), choosing a model with moderate capacity like 256GB or even 128GB is usually sufficient.
Social applications like X and Instagram, as well as instant messaging apps like WhatsApp and Telegram, quietly accumulate a large amount of cache data over time—perhaps even up to 15GB or more. If you find your phone running out of storage space, you can clear the cache of these apps without having to delete any photos or videos.
