Processors and memory The Nokia N9 is powered by a
Texas Instruments OMAP 3630 which is a
System-on-a-chip based on a 45 nanometer CMOS process. It includes three processor units: a 1 GHz ARM Cortex A8
CPU which runs the operating system and applications, an
Imagination Technologies PowerVR SGX530
GPU supporting
OpenGL ES 2.0 and capable of processing up to 14 million polygons per second; and a 430 MHz TI TMS320C64x, a
digital signal processor, which does image processing for the camera, audio processing for telephony and data transmission. The system also has 1 GB of low power single channel RAM (
Mobile DDR).
Compcache uses part of this memory as compressed fast swap. It was, at the time, the most powerful device Nokia created. All user data is stored on the internal
eMMC chip; in 16 and 64 GB variants. The N9 was the first smartphone to include 64 GB of internal storage.
Screen and input Nokia N9 has a
capacitive touchscreen (up to 6 simultaneous points) with a resolution of 854 × 480 pixels (
FWVGA, 251
ppi) in
PenTile RGBG layout. According to Nokia, it is capable of displaying up to 16.7 million colors. The OLED screen is covered by a curved scratch-resistant Corning Gorilla glass. The gap between the glass and the display was reduced in comparison to older Nokia models and the screen is coated with an anti-glare polarizer to ease the usability in daylight. There is a proximity sensor which deactivates the display and touchscreen when the device is brought near the face during a call. It has also an ambient light sensor that adjusts the display brightness. The device also makes use of its accelerometer to rotate the screen in portrait/landscape mode for some applications, such as the web browser.
GPS N9 has an autonomous
GPS feature with optional
A-GPS functionality, Wi-Fi network positioning, a magnetometer, and comes pre-loaded with
Nokia Maps and Nokia Drive applications. Nokia Maps is similar to Ovi Maps found on recent Symbian devices from Nokia and is mostly about finding nearby places (restaurants, metro station, theater, etc...) around the user. Nokia Maps for MeeGo is also integrated with the Contacts and Calendar applications. Nokia Drive is a dedicated application for car navigation and provides free lifetime turn-by-turn voice guided car navigation. The Nokia N9 comes with preloaded maps of the continent where it was purchased, and as such, Nokia Drive does not require an active data connection and can work as a stand-alone GPS navigator.
Camera The main (back) camera has an
autofocus feature, dual
LED flash, is optimized for 16:9 and 4:3 aspect ratios, and has a 4×
digital zoom for both video and camera. The sensor size of the back camera is 8.7 megapixels (3552 × 2448 px); the effective resolution for the 16:9 aspect ratio is 3552 × 2000 px (7.1 megapixels), and 3248 × 2448 px (8 megapixels) for the 4:3 aspect ratio. Typically, a 16:9 picture format on a digital camera is achieved by cropping the top and bottom of a 4:3 image, since the sensor is 4:3. Nokia N9 genuinely provides more in the width of the picture by choosing the 16:9 aspect ratio option by using the full 3552-pixel width of the sensor, and more in the height of the picture by choosing the 4:3 aspect ratio option by using the full 2448-pixel height of the sensor. The
Carl Zeiss lens has quite unusual specifications for a mobile phone: 28mm
wide-angle lens focal length, fast (for this class) f/2.2
aperture, and a 10 cm-to-infinity focus range. It is capable of recording up to 720p video at 30
fps with stereo sound.
Buttons When holding the device facing the screen, on the right side, there is a power on/off (long press), lock/unlock (short press) button and volume keys. The Nokia N9 has fewer hardware buttons than most smartphones of this time and makes extensive use of the touchscreen to navigate the user interface. For example, to minimize a running application, the user has to swipe their finger from one side of the bezel surrounding the screen to the opposite side. There is also no dedicated shutter key for the camera; the touch screen is instead used to focus and take the picture. The screen can be unlocked by double tapping on it.
Audio and output The N9 has two microphones and a loudspeaker situated at the bottom of the phone. The main microphone enables conversation and recording. The second microphone is located on the back of the device near the flash LEDs and main camera, it is used by MeeGo system for
noise cancellation which make phone conversations clearer in noisy environment. On the top, there is a 3.5 mm AV connector which simultaneously provides stereo audio output, with support for
Dolby Headphone, and either microphone input or video output. Next to the 3.5 mm connector, there is a
High-Speed USB 2.0 USB Micro-B connector provided for data synchronization, mass storage mode (client) and battery charging. The USB connector is protected by a small door. However, an FM radio application is available on the OVI Store from an independent developer. NFC is also supported for sharing photos, contacts, or music with other devices supporting NFC (e.g.
Nokia C7,
Nokia 701) and also pairing (connecting) stereo speakers (e.g.
Nokia Play 360) and headset (e.g.
Nokia BH-505). More than one device can be connected simultaneously with N9 via NFC.
Battery The Nokia N9 has a BV-5JW 3.8V 1450mAh battery. The battery is not user-removable. According to Nokia, this provides from 7 to 11 hours of continuous talk time, 16 to 19.5 days of standby, 4.5 hours of video playback and up to 50 hours of audio playback. == Accessories ==
