Thinness was at odds with autonomy, at least until the arrival of silicon-carbon batteries. This combination of components has achieved an authentic battery with a screen and camera without detracting from any of the main features of a premium smartphone. And I think few orchestrate it like the new Motorola Signature 27. If I already liked last year’s Motorola Signature, I think the brand knows how to improve on something already very good.
If the high-end mobile segment already has a serious contender for the 2027 podium, then Motorola enters the competition fully thanks to the Signature 27. It differs in several important ways, such as being the first commercial smartphone to use the best of Qualcomm: the Snapdragon 8 Elite Extreme Gen 6. And with it comes another intriguing piece of software with mobile specs: GrapheneOS.

A mobile phone is designed to be portable while taking up minimal space


If the first Signature surprised me with its thinness and finish, although it did not do without a huge battery, in this Signature 27 Motorola has rounded that relationship with the design both outside and inside. The new mobile is at the top of a catalog 7,000 mAh battery in just 7.99 mm body. Of course, with some deception, since it is dense in the camera area. It’s still normal.

The Motorola Signature is thinner without compromising its autonomy, which should last about two or three days of moderate use. And when it’s time to plug in, its 90W charging promises use in just 12 minutes; It supports 50W wireless charging. Of course, just because it’s thin doesn’t mean it’s light, because quality is “heavy.” 227 gramsspecifically
Do you want to have more numbers to impress on your mobile? Motorola makes sure that the phone’s screen reaches 12,000 nits brightness. Of course, the maximum brightness: this is measured at 1% of the screen. Motorola Signature 27’s HBM didn’t deliver brightness, which is really interesting.
Should have plenty of power, not in vain it reveals the best version of Qualcomm’s reference SoC. This points to the high quality of compatible games; watered with Refresh rate up to 120 Hz Provided by the phone’s 6.78-inch screen.
Motorola Signature 27 is a declaration of love for power, versatility and possibilities. On the outside it’s a beautiful phone, with finishes usually only seen on Motorola and with Pantone colors that match the different versions of the phone very well. In addition, it stands out only from the outside, since the brand has sealed an unusual collaboration: Signature 27 It is the first Motorola mobile phone compatible with GrapheneOS.
This operating system is an adaptation of Android with a focus on security and privacy. GrapheneOS steers clear of Google apps and services, though it supports subsequent installations without too much trouble. Motorola has developed it together with the GrapheneOS Foundation and will provide more details in the coming months.
It’s great news that Motorola makes its most premium mobile phone compatible with it, and not only does it offer options: it’s proof that the Motorola Signature 27 can become the phone for those who care most about their privacy. And they may have that mobile without giving up powerIts camera set clearly displays.
Hardware and software performance is more than enough. And the camera? Well, same, at least on paper: the Motorola Signature 27 debuts a 50-megapixel Sony LYTIA L910 sensor as its main sensor. It aims to be bright and retain detail, color and naturalness: the phone combines its f/1.6 aperture and 3.5° optical stabilization with LOFIC technology, which extends the dynamic range so that video doesn’t burn out at concerts or on neon-lit streets.
Another important aspect is the telephoto: in addition to including a periscopic lens, the Motorola Signature 27 mounts a 200 megapixel sensor to capture more detail from even the most distant objects. It offers 3x optical magnification and goes up to 100x with Super Zoom Pro, which relies on AI to preserve color and sharpness.
An Ultra completes the set 50 megapixel wide angle (It groups four pixels into one, so photos come out at an effective 12.5MP) and a 50-megapixel front camera that records 4K video. And there’s a curiosity: according to Motorola, it’s the first mobile phone with a dedicated EVS action sensor, an event vision sensor that detects light changes at every pixel to quickly freeze subjects with an action shot function.
Motorola has refined its vision of the definitive smartphone with a proposal that tries to include as much as possible in minimal thickness. I think that’s the definition “Air Mobile” to recommendWhich gives you a premium experience in all details. Something that pays for too: The Motorola Signature 27 is right behind the Motorola Fold in terms of cost.
