This OnePlus 13s review starts with something that has become strangely difficult to find: a genuinely powerful Android phone that does not feel enormous in your hand.
The 13s has a 6.32-inch display, weighs 185g and measures just 71.7mm across.
Inside, however, OnePlus has fitted Qualcomm’s Snapdragon 8 Elite processor, 12GB of LPDDR5X RAM and a 5,850mAh battery.
That combination is unusual.
Compact phones normally force buyers to compromise on battery size, performance or both. OnePlus is trying to avoid that trade-off.
It has made compromises elsewhere instead.
There is no ultrawide rear camera, the familiar OnePlus Alert Slider has disappeared, and several features found on larger premium flagships have been simplified.
That makes the OnePlus 13s an interesting phone because its priorities are unusually clear.

A compact phone that is actually compact
Manufacturers have stretched the definition of “compact” over the years.
The OnePlus 13s makes a stronger case than most.
Its 150.8 × 71.7mm footprint is meaningfully smaller than the giant Ultra and Pro Max phones that dominate premium ranges, and its 185g weight is manageable by modern flagship standards.
The 6.32-inch screen still provides enough room for videos, games and typing without turning the phone into something that constantly needs two hands.
That could be the 13s’ greatest selling point.
There are plenty of fast phones.
There are plenty of phones with large batteries.
Combining both in a body this size is much less common.
The new Plus Key replaces a OnePlus classic
Long-time OnePlus users will immediately notice something missing.
The Alert Slider is gone.
In its place is the Plus Key, a programmable button that can be assigned to functions including sound modes, Do Not Disturb, the camera, torch, recorder and OnePlus’ newer AI features.
Whether that is an upgrade depends on what you valued about the old slider.
The Alert Slider was brilliantly simple. You could feel which sound mode the phone was in without looking at the screen.
The Plus Key is more flexible, but flexibility is not always the same thing as convenience.
New buyers may prefer the additional customisation.
Existing OnePlus fans may need more convincing.
Display: small does not mean basic
The 6.32-inch LTPO ProXDR display has a 2640 × 1216 resolution and density of 460 pixels per inch.
Its refresh rate can move between 1Hz and 120Hz depending on what is being displayed, helping balance smoothness with power consumption.
OnePlus lists normal brightness at 800 nits and high-brightness mode at 1,600 nits. The panel also supports 10-bit colour and the P3 colour gamut.
The relatively narrow bezels help make good use of the smaller chassis.
For people who have avoided compact phones because they associate them with second-tier screens, the 13s is reassuringly high-end.
Snapdragon 8 Elite makes this a real flagship
There is nothing mid-range about the processor.
The Snapdragon 8 Elite is the same class of Qualcomm chipset used in much larger premium phones.
It uses Qualcomm’s Oryon CPU architecture alongside the Adreno 830 GPU.
OnePlus also uses a large vapour chamber to manage heat inside the smaller chassis.
That cooling system is important.
Putting a very powerful processor into a smaller phone is straightforward. Keeping it performing well when the chassis heats up is the harder problem.
Without our own controlled thermal and gaming testing, we cannot claim that the 13s maintains a particular frame rate indefinitely.
What we can say is that OnePlus has clearly designed the cooling system around sustained performance rather than treating the Snapdragon badge as a marketing exercise.
For everyday use, the amount of power available should provide plenty of headroom for heavy multitasking and demanding apps.
Gaming on a smaller phone
The 13s is particularly interesting for mobile gaming.
OnePlus promotes high-frame-rate gaming support and includes bypass charging.
Bypass charging can feed power directly to the phone during demanding use while reducing how much energy passes through the battery.
That can help reduce unnecessary battery wear and heat during long gaming sessions.
Manufacturer gaming figures should still be treated as manufacturer figures rather than independent benchmarks.
The broader point remains convincing: this is a small phone with hardware normally found in much larger performance devices.
How did OnePlus fit a 5,850mAh battery in here?
This is arguably the most impressive specification.
The OnePlus 13s contains a 5,850mAh battery despite its relatively compact dimensions.
It also supports 80W SUPERVOOC charging.
Battery capacity alone never guarantees endurance. Display brightness, mobile signal, gaming, camera use and background apps all influence how long a phone lasts.
Still, putting 5,850mAh into a 185g device gives the 13s a much better starting point than many smaller phones.
The lack of wireless charging is one area where some larger premium flagships retain an advantage.
Cameras: good choices, one obvious omission
OnePlus gives the 13s two 50MP rear cameras.
The main camera is joined by a 50MP telephoto camera offering 2x optical zoom.
The front camera is 32MP and includes autofocus.
That setup has an obvious missing piece.
There is no dedicated ultrawide rear camera.
Some buyers will barely care.
A useful telephoto lens is arguably more valuable for portraits and everyday photography than a mediocre ultrawide.
But if you frequently photograph architecture, groups of people, interiors or landscapes, the missing ultrawide is a genuine limitation.
OnePlus also includes computational tools such as AI Detail Boost, AI Unblur, Reflection Eraser and AI Reframe. Availability of some AI functions can depend on software version, region and language.
OxygenOS and AI features
The 13s uses OnePlus’ OxygenOS platform.
OnePlus has increasingly integrated AI into the interface, including its Mind Space features and Google Gemini integration.
The Plus Key can also be used to capture information into OnePlus’ AI tools.
Some people will find that useful.
Others may use the button for the torch and forget the AI features exist.
That is actually one of the strengths of the programmable approach: you do not have to build your workflow around OnePlus’ preferred use.
Connectivity is a bigger part of the story than usual
OnePlus has fitted the 13s with additional hardware intended to improve Wi-Fi reliability and antenna performance.
This is the kind of feature that rarely sounds exciting on a specification sheet but can have a meaningful impact if you live or work in an area with inconsistent connectivity.
OnePlus also promotes cross-platform file sharing with Windows, macOS and iOS through its O+ Connect software.
What the OnePlus 13s gets right
The concept is refreshingly focused.
OnePlus has resisted turning the 13s into a miniature version of every feature found on its biggest flagship.
Instead, it concentrates on performance, battery capacity, screen quality and manageable dimensions.
That combination makes sense.
A smaller phone does not need four rear cameras and a giant zoom module to be desirable.
It does need enough battery to survive normal use and enough performance that choosing the smaller model does not feel like accepting second best.
What you give up
The missing ultrawide camera is probably the clearest sacrifice.
Some long-time OnePlus users will also miss the Alert Slider.
The camera system is capable on paper, but it does not offer the sheer flexibility of larger camera-focused flagships.
And while the 5,850mAh battery and 80W wired charging are impressive, buyers wanting a fully loaded premium feature set may still prefer a larger flagship.
OnePlus 13s pros and cons

Who should buy the OnePlus 13s?
Buy it because you want a small phone.
That sounds obvious, but it is the entire point of the 13s.
If you love large screens, there are dozens of excellent alternatives.
If you are tired of carrying a 6.7-inch slab but refuse to sacrifice flagship performance and battery capacity, the OnePlus 13s becomes far more interesting.
It is particularly attractive to commuters, mobile gamers and anyone who regularly uses a phone one-handed.
Final verdict
The OnePlus 13s succeeds because its compromises make sense for a very specific audience.
It gives up some camera flexibility and retires a beloved OnePlus hardware feature, but in exchange you get Snapdragon 8 Elite performance, a large battery and a high-quality LTPO display in a genuinely manageable body.
That is a trade many people have been waiting for.
The 13s is not the most feature-packed Android flagship.
It does not need to be.
It is one of the more convincing attempts to prove that a powerful phone can still fit comfortably in your pocket.
