Introduction
Big screen phones are no longer a luxury. In 2026, some of the most impressive large-display smartphones are available for well under £100 — making it easier than ever to enjoy an immersive viewing experience without spending a fortune.
Whether you want a phone for streaming, gaming, social media, or simply because a larger screen is easier on the eyes, you don't need to spend £700 on a flagship to get a great display. In this guide, we round up everything you need to know about finding the best big screen phones under £100 in the UK right now.
Why Big Screen Phones Are More Popular Than Ever in 2026
The trend toward larger smartphone displays has accelerated significantly. <cite index="8-1">Large-screen phones — those with displays of 6.5 inches and above — have transitioned from niche to mainstream, now accounting for a significant majority of global Android shipments with continued year-over-year growth.</cite>
It's not hard to see why. A larger screen makes everything better:
Streaming and video — films, YouTube, and TikTok are significantly more enjoyable on a 6.5-inch+ display
Social media — scrolling Instagram, Facebook, or browsing the web is far more comfortable
Productivity — emails, spreadsheets, and multitasking are easier with more screen real estate
Gaming — a larger display gives you a better view and more precise controls
Accessibility — bigger text and larger icons make the phone easier to use for everyone
The good news? You no longer need to spend hundreds of pounds to enjoy these benefits.
What to Look for in a Big Screen Phone Under £100
Before buying, here are the key specs to check:
Screen Size
For a genuinely large screen experience, look for at least 6.5 inches. Anything above 6.7 inches puts you in premium territory — even at budget prices.
Screen-to-Body Ratio
A high screen-to-body ratio (above 85%) means less bezel and more screen. This makes a huge difference to the viewing experience, giving you more display in the same physical phone size.
Display Resolution
Look for at least HD+ (1600 x 720) resolution. At budget price points, HD+ is standard and perfectly sharp for everyday use.
Battery Life
Bigger phones need bigger batteries. A screen of 6.5 inches or more should come with at least a 4,000mAh battery to get you through a full day.
Camera Quality
For social media and everyday photography, look for at least a 13MP rear camera. Many budget big-screen phones now offer significantly more.
Dual SIM Support
Most budget Android phones in 2026 include dual SIM support — a useful feature for keeping work and personal numbers separate or saving money by mixing networks.
