The Bold Front
The overall experience is remarkably smooth, but we aren't exactly crediting it to the 624MHz processor within. Incidentally, this is the same processor powering its predecessor. Considering that, we think the renewed BlackBerry 6 OS has a hand in the Bold 9780's smooth performance. Other than what we've mentioned about some difficulty with its user interface due to its trackpad, we found the experience to be pleasantly fluid.
Given its modest screen size, watching videos on the Bold 9780 could be straining on your eyes. We do have to agree on its smooth rendering of our test videos, and audio quality wasn't too shabby either. Its final multimedia feature, the 5-megapixel camera, is one of the highlights of the Bold 9780. We'll let its images speak for itself.
As you can see, color reproduction on the 5-megapixel camera was decent, with a good balance across the various hues. Its details and sharpness levels were average as seen on the resolution chart. This was also apparent with our standard test image, though the tighter edges could turn up slightly muffled in details.
Moving on with one of our core evaluation of a mobile device, we subjected the Bold 9780 to a battery test. As usual, our test parameters include the following conditions:
1. Screen brightness at 100%
2. Audio volume at 100%
3. Wi-Fi and Bluetooth active. Data is being constantly pulled via Twitter and BES (BlackBerry Enterprise Server).
4. Running a video encoded at 240 x 320 pixels resolution on an endless loop.
With these conditions set in place, we now examine the Bold 9780's battery performance against devices with similar features. As such, we're looking at display sizes and resolution, its accompanying processor. We've also included comparisons between the weight and dimensions to calculate the portability index of the device.
|Specifications/Device||BlackBerry Bold 9780||BlackBerry Bold 9700||Nokia E72||Sony Ericsson Xperia X10 mini|
|Display Type||TFT||TFT||TFT||TFT capacitive|
|Display Resolution||480 x 360 pixels||480 x 360 pixels||320 x 480 pixels||240 x 320 pixels|
|Dimensions||109 x 60 x 14mm||109 x 60 x 14mm||114 x 58 x 10mm||83 x 50 x 16mm|
|Battery||1500 mAh||1500 mAh||1500 mAh||950 mAh|
The Bold 9780's results show a slight drop in its stamina, as compared to the earlier Bold 9700. With the same display size, resolution and processor, this leads us to believe that the updated BlackBerry 6 OS comes with a slight dip in power management.
Since its dimensions and weight is retained at the same levels as its predecessor, the only condition that affects its portability index comes from its battery life. As such, you'll find a lower portability index from the Bold 9780. Looking across the comparisons, you'll find the Bold 9780 to be the lesser of the four, though it does come with an above average battery life span at 5 hours 24 minutes and a reasonable portability index.
Theoretical benchmarking aside, we conducted our usual routine by using the phone as our main mobile device to see how does it fare in more practical usage. We did get a better mileage out of it, with nearly two days of constant emails streaming in. Incoming calls were minimal during this period, but we compensated for that with heavier internet activity by using its web browser and social networking.
