Best Slim Phones In 2026: The Thinnest You Can Buy

The thinnest phone you can buy in November 2026 is no longer a flat slab, because Samsung’s Galaxy Z Fold8 Ultra opens to just 4.1mm.

If you want a phone that is thin in your pocket all the time, the slab-style iPhone Air and Galaxy S25 Edge still lead, so this list covers both kinds.

Quick picks: which slim phone should you buy?

Foldables are only thin when open, so the folded thickness is listed too.

5. Galaxy Z Fold8: cheaper thin foldable

The standard Fold8 opens to 4.5mm and weighs 201g, which Samsung says makes it its lightest Fold yet.

Pros:

• 7.6-inch main display and 5.5-inch cover screen

Is the Motorola Edge 70 sold in the US?

No, Android Central reports the Edge 70 is not sold in the US.

It measures 5.99mm, weighs 159g and carries a 4,800mAh battery, so it is a useful benchmark for what a slim phone can do with battery size.

Thickness, weight and battery compared

Why are ultra-thin slab phones disappearing?

Notebookcheck reported in November 2025 that iPhone Air sales were weak and that a Galaxy S26 Edge had reportedly been scrapped.

In September 2026 it reported that Apple is keeping the iPhone Air unchanged, with new models rumored for spring 2027.

That makes both slab phones here the current end of their lines, so buy them for the design rather than for a promised update.

How to choose a slim phone

• Slimmest in your pocket: pick the iPhone Air or Galaxy S25 Edge, since foldables are 8.9mm to 10.1mm closed.
• Biggest screen in the thinnest body: pick the Galaxy Z Fold8 Ultra.
• Battery matters most: pick a foldable, because their cells are 4,800mAh or larger.
• Camera matters most: the S25 Edge and Fold8 Ultra both have 200MP main cameras.

When did each phone launch and what storage does it come in?

The two slab phones are a year or more old, while the three foldables arrived this summer.

Our verdict

Buy the Galaxy Z Fold8 Ultra if you want the thinnest open profile and can pay $2,099, or the Galaxy S25 Edge if you want a slim slab at a discount.

Choose the iPhone Air if you want the thinnest slab and are fine with an eSIM and a smaller battery.
