As the end of the year approaches, many people start wondering whether it is time to upgrade their phone. Ultra-class flagships are the biggest and best-equipped models in a manufacturer's range: large screens, big batteries and plenty of storage. This guide gives a short, honest overview of what to consider before buying and which models you can find at SHOPRO.LT.

What does an "ultra" flagship mean?

There is no official definition, but it usually refers to a brand's largest and best-equipped phone. Such models typically have a screen of around 6.9 inches, plenty of RAM and storage, and a large battery. They suit people who use their phone as their main tool for work, photography and entertainment.

These phones are not small or light, so think about whether a big device feels comfortable in one hand before you buy.

What to look at when choosing

  • Screen size and dimensions. A 6.9-inch display is great for films and work, but the phone takes more room in a pocket.
  • Battery and charging. Capacity (mAh) matters, but so does the maximum supported charging power.
  • Storage. If you take lots of photos and videos, choose more internal storage, as you cannot add it later.
  • Durability and repairability. The IP rating and repairability class show how the phone is likely to cope with everyday use.
  • Ecosystem. If you already use Apple or Android services, switching costs time and effort.

How to choose for your needs

  • You want a big screen and proven protection: look at the Galaxy S26 Ultra with its IP68 rating.
  • Storage and battery come first: the Xiaomi 17 Ultra has 16 GB and 512 GB plus a 6000 mAh battery.
  • You use Apple devices: the iPhone 18 Pro Max fits neatly into your existing setup.
  • You want something lighter and more affordable: compare the Honor 600 Pro and the Nothing Phone 4a Pro.

Before you buy

  • Check whether a charger is included. The Samsung Galaxy S26 Ultra and Honor 600 Pro listings state that no AC adapter is supplied, so you may need to buy one separately.
  • Make sure the storage (for example 256 GB or 512 GB) is enough for you.
  • Think about whether the size and weight suit you.
  • Check current availability and the full specification on the product page.
