OnePlus Open 2 vs Oppo Find N5: Thin Design Potential

Updated 4 November 2026 · Standard formula, shown below

Yes, the OnePlus Open 2 is widely expected to be inspired by the Oppo Find N5’s potential thin design, as both companies share a parent organization and have historically released near-identical foldables under different brands. Based on leaks and the established pattern of the OnePlus Open and Oppo Find N3 being the same device, the OnePlus Open 2 will likely mirror the Find N5’s rumored slim profile, possibly measuring under 10mm when folded. This article explains what that means for you, how the shared engineering works, what to expect, and how to decide if this upcoming foldable is worth waiting for.

Background: OnePlus and Oppo’s Shared Foldable Lineage

OnePlus and Oppo have been under the same parent company since 2021, and their foldable phones have been rebadged versions of each other. The original OnePlus Open (2023) was essentially the Oppo Find N3 with OnePlus software and a slightly different camera tune. This means the OnePlus Open 2 will almost certainly be the Oppo Find N5 with OnePlus branding, just as the Find N3 became the Open.

This shared lineage is why rumors about the Find N5’s design directly apply to the Open 2. When Chinese tech media reports on the Find N5’s thinness, they are effectively reporting on the OnePlus Open 2’s physical dimensions. The two phones are developed on the same assembly line, with the same hinges, displays, and internal chassis.

How Thin Could the OnePlus Open 2 Actually Be?

Current foldables like the Galaxy Z Fold 6 measure about 12.1mm folded, while the original OnePlus Open was 11.7mm. Leaks from late 2024 and early 2025 suggest the Find N5/Open 2 could reduce that to around 9.2mm to 9.5mm when folded. That would make it thinner than many non-foldable phones with cases, and significantly slimmer than any book-style foldable currently on the market.

To achieve this, Oppo is reportedly using a new hinge design with fewer moving parts and a custom ultra-thin glass. The battery is also being redesigned to be slimmer while keeping a capacity around 5,500mAh. The trade-off is that the camera module may protrude more, as the main sensor stack cannot be shrunk indefinitely.

What the Shared Design Means for You

If you are considering the OnePlus Open 2, the shared design has three practical implications:

Software updates: OnePlus will likely ship OxygenOS, while the Oppo version uses ColorOS. Both are based on the same Android core, but OnePlus users get a cleaner UI with fewer pre-installed apps.
Availability: The Oppo Find N5 may launch first in China, with the OnePlus Open 2 following in global markets weeks later. This is exactly what happened with the Find N3 and Open.
Accessories: Cases and screen protectors for the Find N5 will likely fit the Open 2, since the dimensions and port placements are identical. This can save you money if you import accessories early.

Common Misconceptions About Thin Foldables

Many assume that a thinner foldable must be more fragile. That is not necessarily true. The hinge is the main structural weakness, not the thickness. A well-engineered thin hinge with a solid locking mechanism can be just as durable as a thicker one. The original OnePlus Open had a hinge that passed 1,000,000 folds in testing, and the Find N5’s new hinge is expected to meet or exceed that standard.

Another misconception is that thinness forces a smaller battery. In reality, battery density improves every year. The Find N5 is rumored to pack a 5,500mAh cell, which is larger than the Open’s 4,805mAh, despite the phone being thinner. This is possible because of silicon-carbon battery technology, which stores more energy per gram than traditional lithium-ion.

How to Decide: Should You Wait for the OnePlus Open 2?

If you already own a OnePlus Open, the upgrade is worthwhile only if you value the thinner profile and better battery life. The camera and display are expected to be similar, with incremental improvements. If you are coming from a slab phone, the Open 2 will be a more pocketable entry into foldables than any previous model.

Consider these factors before committing:

Your current phone’s age: If it is over two years old, waiting for the Open 2 makes sense. If it is less than a year old, the upgrade may not justify the cost.
Your tolerance for camera bumps: The Open 2 will likely have a visible camera bump on the back to accommodate the sensor. If you prefer a flat back, this may bother you.
Your need for wireless charging: The original Open had it, and the Find N5 is expected to keep it. If you rely on wireless charging, confirm this before buying.

Comparison: OnePlus Open 2 vs. Current Foldables

Compared to the Galaxy Z Fold 6 and Pixel Fold, the OnePlus Open 2 is expected to be:

Thinner: At roughly 9.5mm folded, it will be about 2.5mm slimmer than the Z Fold 6.
Lighter: Likely under 230 grams, compared to the Z Fold 6’s 239 grams.
Faster charging: The Open 2 is rumored to support 80W wired charging, versus the Z Fold 6’s 25W.
Similar camera: The Open 2 will keep the 50MP main and periscope telephoto, but the ultrawide may stay at 48MP.

The main disadvantage is the lack of an official IP rating for dust resistance. The original Open had IPX4 (splash only), and the Find N5 may not improve on that due to the hinge’s moving parts.

Potential Drawbacks and Risks

Thinness introduces a few risks you should know about:

Thermal throttling: Less internal space means less room for heat dissipation. Under heavy gaming, the Open 2 may throttle sooner than thicker foldables.
Repair complexity: The new hinge may be harder to repair, potentially increasing out-of-warranty costs.
Crease visibility: A thinner display stack can make the crease more noticeable, though Oppo’s latest UTG (ultra-thin glass) may mitigate this.

There is also the risk of launch delays. The Find N5 was originally expected in Q1 2025, but some reports suggest it may slip to Q2. OnePlus has not confirmed any date, so treat rumors with caution.

Frequently Asked Questions

Will the OnePlus Open 2 be exactly the same as the Oppo Find N5?

Yes, in terms of hardware. The only differences will be the software skin (OxygenOS vs. ColorOS) and possibly the camera tuning. The physical dimensions, battery, and display will be identical.

When will the OnePlus Open 2 be released?

No official date has been announced. Based on the pattern of the original Open, which launched in October 2023, the Open 2 could arrive in late 2025, but some leaks point to a mid-year release. Watch for Oppo’s China launch, which typically happens a few weeks before the global OnePlus release.

Is a thinner foldable more fragile?

Not necessarily. The hinge design matters more than thickness. The Find N5’s hinge is expected to be as durable as the Open’s, which was rated for 1,000,000 folds. However, the thinner frame may be more susceptible to bending under extreme pressure, so a case is recommended.

Will the OnePlus Open 2 have a better camera than the original?

Expect minor improvements, not a major overhaul. The main sensor may get a slightly larger aperture, and the periscope telephoto might support longer zoom. But the overall camera system will be similar to the Open’s, which was already excellent.

Can I use the Oppo Find N5 case on the OnePlus Open 2?

Yes, if the dimensions are identical, which they are expected to be. However, the camera module placement must match exactly, so wait for confirmation from third-party accessory makers before buying.

Is it worth upgrading from the OnePlus Open?

Only if you prioritize thinness and battery life. If you are happy with your current phone’s size and battery, the upgrade will feel incremental. For new buyers, the Open 2 will be the best foldable value on the market.
