How big are the displays in large screen smartphones?
Large screen smartphones have displays that measure around 6.7 to 7.6 inches. You usually find screens in this range on devices called "phablets" or foldables, which push screen size near tablet levels.
Many flagship models now sit at 6.7 or 6.8 inches. These phones give you more space for gaming, streaming, or split-screen multitasking. Foldable smartphones like the Samsung Galaxy Z Fold series expand the display size even more—up to 7.6 inches when unfolded. Some brands also reduce bezels to fit larger displays without increasing overall phone size. You get high refresh rates, AMOLED or OLED panels, and higher resolutions like QHD+ in most of these large screen models.

Do big displays use more battery?
Yes, big displays use more battery. If your phone has a display of 6.6 inches or more, it consumes more power than smaller screens. This happens because the screen lights up a larger surface area and needs more energy to refresh pixels.
You also tend to keep brightness higher on bigger displays, especially when outdoors, which drains the battery faster. High resolution (like Full HD+ or QHD) and higher refresh rates (90Hz or 120Hz) also increase power draw.
You may not notice fast battery drain right away if your phone has good software optimization or a large battery. But over time, a big display still uses more battery during video playback, gaming, or browsing. If you use a phone with a 6.6-inch or larger screen, go for a battery size of at least 5000mAh. We recommend a 6000mAh battery if you want longer screen time and fewer daily charges.
Do large-screen phones cost more than regular phones?
Large-screen phones cost more than regular phones. You usually pay a higher price because of the display size, premium build materials, and higher-end specs that brands include in these models.
Manufacturers often place large-screen phones in the flagship category. These phones use bigger and sharper OLED or AMOLED panels, and brands pair them with faster processors, better cameras, and larger batteries. That increases the cost. For example, phones with screens above 6.6 inches often start from £700 to over £1,200, while regular phones with screens around 6.1 to 6.4 inches can fall between £260 and £700. You also see more expensive materials like aluminum frames or ceramic backs in large-screen models, while regular phones use plastic or lower-grade metal.
