After months of teasers and a September preview, Motorola has finally taken the wraps off the Signature 27, the highly anticipated successor to the original Signature. The company had already confirmed Bang & Olufsen audio and showcased the device in a hands-on promo video, but today marks the full official unveiling. And the biggest mystery—the battery capacity—has been solved: it’s a massive 7,000 mAh cell, which is 35% larger than what the predecessor offered.
A Battery That Goes the Distance
The 7,000 mAh battery is undoubtedly one of the headline features of the Signature 27. In a world where flagship phones often settle for 5,000 mAh, Motorola is pushing the boundaries of endurance. This 35% increase over the previous generation means users can expect significantly longer usage between charges—whether streaming video, gaming, or working on the go. The battery supports fast charging, though Motorola hasn’t specified the exact wattage yet, but we expect it to be competitive with other premium devices.
What does this mean in real-world terms? For heavy users, it could easily translate to two full days of moderate use, or at least a full day of intense activity without hunting for a charger. The larger battery does add a bit of weight and thickness, but Motorola has managed to keep the design sleek and premium, according to early hands-on impressions.
Display: Extreme AMOLED Duo Shines Bright
The Signature 27 features a 6.78-inch 1.5K “Extreme AMOLED Duo” screen. This isn’t your average AMOLED—it uses a tandem panel with two emissive layers, which typically results in higher brightness, better efficiency, and improved longevity. The 120Hz refresh rate ensures buttery-smooth scrolling and gaming, while the peak brightness of 12,000 nits is simply staggering. That’s not a typo: 12,000 nits. This means the display remains perfectly readable even under direct sunlight, and HDR content will look absolutely stunning with incredible highlights and deep blacks.
The tandem structure also helps reduce power consumption, which complements the large battery nicely. Whether you’re watching HDR videos or browsing in bright outdoor conditions, the Extreme AMOLED Duo is designed to impress. Motorola has also included support for a wide color gamut and likely HDR10+ certification, though we’ll confirm that once we get our hands on a review unit.
Design and Build: Premium All Around
Motorola has always had a knack for stylish designs, and the Signature 27 continues that tradition. The phone is built with a metal frame and glass back, available in several color options that include a signature vegan leather variant. The curved edges make it comfortable to hold despite the large battery, and the IP68 rating for water and dust resistance adds peace of mind. The dedicated action sensor is a new addition—more on that below—and it’s seamlessly integrated into the frame, not disrupting the clean lines.
On the front, the 6.78-inch display is surrounded by slim bezels, with a small punch-hole cutout for the selfie camera. The under-display fingerprint sensor is present and is said to be faster and more accurate than before. Overall, the Signature 27 looks and feels like a true flagship, ready to compete with the best from Samsung, Apple, and Google.
Performance: Flagship Power
Under the hood, the Signature 27 is powered by Qualcomm’s latest Snapdragon 8 Gen 3 processor, paired with up to 12GB of RAM and 512GB of storage. This combination ensures top-tier performance for gaming, multitasking, and AI-driven tasks. Motorola has also optimized the software for smooth operation, and the phone runs Android 14 out of the box with Motorola’s My UX on top.
The Snapdragon 8 Gen 3 is known for its efficiency and powerful Adreno GPU, so gamers can look forward to high frame rates and responsive controls. The phone also features an advanced cooling system to keep temperatures in check during extended gaming sessions. With the large battery, you can game for hours without worrying about running out of juice.
Camera: Versatile and Capable
The camera setup on the Signature 27 is impressive. The rear houses a 50MP main sensor with OIS, a 50MP ultra-wide lens, and a 12MP telephoto lens with 2x optical zoom. This triple-camera system is versatile enough for any situation, from landscapes to portraits. Motorola has also improved its computational photography, with better night mode and HDR processing.
The 50MP main sensor uses pixel binning to produce 12.5MP images with excellent detail and dynamic range. The ultra-wide doubles as a macro shooter, and the telephoto provides a nice portrait focal length. On the front, a 32MP selfie camera ensures sharp and vibrant self-portraits. Video recording supports up to 8K at 30fps and 4K at 60fps, with stabilization for smooth footage.
Audio: Bang & Olufsen Tuned
As previously teased, the Signature 27 features audio tuned by Bang & Olufsen. The stereo speakers deliver rich, balanced sound with deep bass and clear highs. Whether you’re watching movies or listening to music, the experience is immersive. There’s also support for hi-res audio and spatial audio, making it a great choice for audiophiles.
No headphone jack, though—that’s been omitted to keep the design slim. But Bluetooth 5.3 and aptX Lossless support ensure high-quality wireless audio. The B&O tuning extends to the included earbuds? No, they’re not included, but the phone’s speakers are among the best in the market.
Dedicated Action Sensor: A New Way to Interact
One of the most intriguing features of the Signature 27 is the dedicated action sensor. This is a physical button or sensor on the side of the phone that can be customized to perform various actions—similar to the Action button on the iPhone 15 Pro. You can set it to launch the camera, toggle the flashlight, start a voice recording, or even trigger a custom shortcut. It’s a small addition but adds a layer of convenience for power users.
The sensor is pressure-sensitive and can distinguish between a short press and a long press, allowing for multiple functions. Motorola has also opened it up to developers, so third-party apps can integrate with it. This could be a game-changer for productivity and quick access to frequently used features.
Software and Features
The Signature 27 runs Android 14 with Motorola’s My UX, which offers a near-stock experience with useful additions like Moto Gestures, Peek Display, and a customizable always-on display. Motorola promises three years of OS updates and four years of security patches, which is decent but not quite matching Samsung’s or Google’s longer support windows.
Other features include 5G connectivity, Wi-Fi 6E, NFC, and an array of sensors. The phone also supports Motorola’s Ready For platform, which allows you to connect to a monitor or TV for a desktop-like experience. With the powerful processor and large battery, it’s a capable productivity tool.
Pricing and Availability
Motorola hasn’t announced official pricing yet, but given the flagship specs, we expect it to be competitive with other premium devices. The original Signature launched at around $800, so the Signature 27 might come in slightly higher, perhaps around $900. It will be available in multiple markets, including North America, Europe, and Asia, starting in the coming weeks. We’ll update this article once we have official pricing and availability details.
Comparison with Predecessor
Compared to the original Signature, the 27 brings several key upgrades: a larger 7,000 mAh battery (up from 5,200 mAh), a brighter and more efficient display, the new action sensor, and improved cameras. The design is also refined, with a more premium feel. It’s a worthy successor that addresses some of the shortcomings of the previous model.
Early Impressions and What to Expect
From the initial hands-on impressions, the Signature 27 feels like a solid upgrade. The battery life is expected to be outstanding, the display is stunning, and the performance is top-notch. The action sensor is a nice touch that adds functionality. However, we’ll reserve final judgment until we conduct a full review, especially regarding camera quality and software stability.
Motorola has been on a roll lately, and the Signature 27 seems poised to continue that momentum. It’s a phone that caters to power users who demand long battery life, a great display, and unique features. Stay tuned for our full review in the coming weeks.
