- Ascend P7
Today Huawei announced the Ascend P7, its new flagship smartphone. The P7 replaces last year’s Ascend P6 and brings significant improvements across the board. Huawei is positioning the device to compete better in the high-end market with improved specs across the board and an improved design which is reminiscent of Apple’s iPhone 4 with sheets of glass on both the front and back of the device and a metal band around the edge. The rest of the known specifications are laid out below.
|Huawei Ascend P7 vs P6|
|Ascend P7||Ascend P6|
|SoC||HiSilicon KIRIN 910T 4 x 1.8GHz Cortex A9 + Mali-450 (28nm HPM)||HiSilicon K3V2 1.5GHz Cortex A9 + Vivante GC4000|
|Memory||2GB LPDDR3||2GB LPDDR3|
|Storage||16GB NAND + MicroSDHC||8/16GB NAND + MicroSDHC (single SIM SKU)|
|Display||5.0” 1920x1080 IPS LCD||4.7” 1280x720 IPS LCD|
|Cellular Connectivity||GPRS/EDGE/DC-HSPA+/Category 4 LTE||2G / 3G HSPA (EvDO China SKU)|
|Dimensions||139.8 x 68.8 x 6.5 mm, 124g||132.7 x 65.5 x 6.2 mm, 120g|
|Camera||13MP (4128 x 3096) Rear Facing Sony Sensor w/ F2.0 aperture, 8MP FFC||8MP (3264 x 2448) Rear Facing Sony Sensor w/ F2.0 aperture, 5MP FFC|
|OS||Android 4.4.2 + Emotion UI 2.3||Android 4.2.2 + Emotion UI 1.6|
|Other Connectivity||802.11a/b/g/n + BT 4.0, USB2.0, GPS/GNSS, DLNA, NFC||802.11b/g/n + BT 3.0, USB2.0, GPS/GNSS, DLNA|
Huawei continues to include their own SoC in their flagship devices. The HiSilicon KIRIN 910T is a quad-core Cortex A9 design with Mali-450 GPU built on a 28nm HPM process. The Cortex A9s are clocked at up to 1.8GHz, which is quite high for a A9 design. I'm curious to see how the high clocked A9s stack up to Qualcomm's Krait 400. I suspect it's a better perf/watt choice to use higher clocked A9s than a high frequency A15, however the driving factor here is probably performance/area and then perf/watt.
The KIRIN 910T features HiSilicon's own integrated LTE modem. For a device aimed at the high-end market this is definitely something needed to be competitive. The P7 will launch with support for LTE Bands 1, 3, 7, 8 and 20. With the exception of Canadians in 2600MHz (Band 7) markets, North American users are out of luck with the international launch SKU. In terms of connectivity Huawei has moved to Bluetooth 4.0 and included support for NFC. The device’s battery capacity increased from 7.6Wh to 9.5Wh. Poor battery life was one of the major complaints about the Ascend P6 and it looks like Huawei doesn’t want to have the same issue this time around (although software tuning can be just as important as hardware/battery selection).
Like other recently launched devices, Huawei is putting big stress on the camera. The Sony-sourced 13MP sensor on the back is fairly standard for today’s high-end Android smartphones but the front camera is much more unique. Huawei has used an 8MP sensor for the device’s front facing camera. This is the next step in what appears to be a very rapid shift in front camera resolution. It was only a year ago that 2MP was the de-facto standard for the front facing camera on flagship smartphones. With the new front camera Huawei is promoting some new software features like front facing panoramas to fit in larger groups of people. In addition, both the front and back cameras are capable of 1080p30 video recording.
In terms of software the device runs Android 4.4.2 with Huawei’s emotion UI on top. Like many recently launched flagship devices, Huawei is touting a feature they call “super power-saving mode” which can dim the display and turn off everything except the basic functions of the phone when the battery is at ten percent or lower. Huawei has indicated that the device will launch in black, white, and pink finishes with a recommended retail price of 449 euros in China, Australia, and Europe sometime around Q3 2014 with other markets to follow later.

willis936 - Wednesday, May 7, 2014 - linkIt's actually hilarious how similar it is to the iPhone edge. However I salute them for blatantly ripping off any "style" IP because it's just ridiculous that they handed those patents out in the first place.
Flunk - Wednesday, May 7, 2014 - linkDesign patents are very specific, this isn't close enough to violate them. Yes, there are similarities but a lot of them are generic things.
MercuryStar - Monday, September 15, 2014 - linkThe greatest trick Apple ever pulled was to convince the world that copying someone else's good ideas was a "bad thing".
Yes this shows the successful and attractive iPhone design had a strong influence. No, that is not illegal, a violation of patents, or a bad thing, as Apple might want you to believe. If taking someone else's good ideas and building upon them was illegal we wouldn't have cars, or toasters, or electricity to the home. This is quite distinct from copyright or patent violation which would involve copying a very specific aspect or technique. I'm sure Apple finds it very convenient that the general public seem to be hazy on what, for example, a design patent can protect.
Achtung_BG - Wednesday, May 7, 2014 - linkKIRIN 910T includes LTE baseband on-die is well. Using 28 nm HPM is also good news. Interesting is the die size on the SoC. Great attention is paid to the cooling of the phone, using a special gel and aluminum alloy.
Wilco1 - Wednesday, May 7, 2014 - link"The HiSilicon KIRIN 910T is a quad-core Cortex A9 design with Mali-450 GPU built on a 28nm HPM process. The Cortex A9s are clocked at up to 1.8GHz, which is quite high for a A9 design. "
A 1.8GHz Cortex-A9 is not high clocked, especially not on 28nm HPM. Tegra 4i does 2.3GHz on the same process.
Kalelovil - Wednesday, May 7, 2014 - linkNvidia markets the Tegra 4i as a 2.3Ghz chip, but the only phones announced so-far featuring it have it clocked at 1.7Ghz or 2Ghz.
Jaheira - Thursday, May 29, 2014 - linkI have/ had the predecessor P6, and I learnded that the electronic compass doesn't work on all those P6 devices. I need it for pedestrian-navigation. Now I wonder if it works on the P7. Plus: is the GPS very mediocre again?
