The recently introduced range of pocket PCs by ASUSTeK contains three models: Asus A600, A620 and A636. The first representative of the product line was tested a few days earlier and today we are examining another one - Asus A686. The device reasonably takes the medium spot between the junior A626 and the senior A696. Asus My Pal A686 carries GPS-module onboard, whereas the A626 comes with nothing of this kind included, but still, it lacks Wi-Fi.

The company positions MyPal A686 as a basic solution packed with GPS-navigation abilities. Its worth mentioning that in spite of by no means cutting-edge display with QVGA-resolution and lack of Wi-Fi the A686 seems to be a competent solution for GPS navigation specifically thanks to the time-proven GPS-chip SiRF Star III, and outstanding battery life.

We should note it beforehand, that in the sense of design all three PDAs are identical. The only things that allow you to tell the difference are GPS label on the casing and the external antenna GPS-antenna slot for the A686 and the A696. If you have read already the review of Asus My Pal A626 you may readily miss the forthcoming paragraph and jump straight to performance an GPS navigation.

Design and controls

The devices looks can be deemed traditional for Asus-branded PDA solutions. Availability of GPS-module in senior models leaves its own stamp on all offerings that belong to the line. In fact, that is why the first launch goes in landscape orientation. The asymmetrically placed display (if put the device in vertical position, it will be a bit closer to the right spine) serves as just another proof that landscape setup is intended for the A686. On the left-hand side sits GPS label.

Measuring 117x70.8x15.7 mm at 165 g, the A626 fits in the image of a todays PDA. The device is larger in size than Acer n311 but is pretty much comparable with other solutions. This PDA is meant to be carried in bag or briefcase in the first place; as although it comes packaged with a carrying case, it has no belt clip. The case made of thick black material features Asus logo on the face and has firm grip on the PDA.

The A686 comes in conventionally-looking rectangular form without protruding details and slightly rounded edges and spines. The PDAs face has metal finish that goes along the perimeter and partly touches the side plates. Black plastic is used for the displays frame. Our review unit had silver front plate; however they are now planning to launch three extra trims: gold, blue and light blue. At that, the only part that varies in color is the front fascia, whereas the rest of the casing remains coated in black.

The rear utilizes standard black plastic, which seems far too unsophisticated and cheap; and naturally the combination of metal and plastic is something we havent used to see too often, which makes for more primitive looks of the A626. This part also features a slot for GPS-antenna covered with a flap.

Beneath the screen, on the face plate, you will find four keys and a round five-way navigation key. Further down on the left is a small speaker grill, on the opposite side is the similarly-patterned grill, hiding wireless interfaces indicator underneath, as for the rest it is here chiefly for the sake of it.

The keys under display are dedicated to the following functions (from left to right): voice notes, contacts, calendar, quick menu, more of which later.

Bulky in size navigation pad stands a bit above the casing surface, which makes it a cinch to work with, as well as with other fascia-mounted keys. Above the screen you will find a small hole, where charging LED is placed.

The left spine plays host to a Mini-USB slot which serves for linking up the PDA with PC or charging up the handheld. The slot is left uncovered. The right-hand side houses two elements: hold switch and 3.5mm audio jack. The elements mentioned, placed both on the spines and on the edges, are placed flush with the casing, which is a reasonable approach in view of GPS-module embedded, implying that the A686 is supposed to be used in car. That is why the casing is made flat with no protruding parts.

Presence of 3.5 mm jack for headphones gives you an opportunity to use Asus A626 as a music player. We tasted sound quality with in-ear headphones Sennheiser MXL 51 and on-ear type - Sennheiser HD-212 Pro. The sound proved to be clear without any unwanted noises. Top volume level is not particularly high, but seems sufficient for using the player on the street. Of course, music-conscious users will definitely turn up their noses at the A626, but our point of view is purely subjective.

The upper edge is armed with the power button and unprotected memory expansion slot. The card format applied here is one of the most wide-spread among PDAs SD/MMC with SDIO support. The biggest memory card you can use with the A686 should be the most capacious unit on the market, just like weve come to expect. Switching to the bottom end, you can see the soft reset key and Infrared window, as well as the stylus silo.

The stylus slides into the silo vertically, if you are holding the A686 sideways, which is quite different from our previous experience. In other words, if you put the device vertically, the stylus socket will be located horizontally at the bottom edge. The advantage of this layout is that whichever way you hold the A626, the stylus will never end up sliding out of the silo on its own.

Stylus is extensible, though it snaps open and closed with authority. When closed, it measures 62 mm tall, and 92 mm when opened. Basing of its thickness and size, we should better say that it is not very easy to use, just average. For most of the PDAs this stick usually turns out to be rather thick. But in this way Asus A626 is inferior even to Acer n311 with its already pretty skinny stylus. Ultimately, you will get used to it, but at first it might seem too small and inconvenient, especially to those who have dealt with other PDAs in the past.


It is one of moot points about the whole of Asuss updated range. The A686 sports touch-sensitive TFT-matrix measuring 3,5 from corner to corner. The active zone of the display at that makes up 70x52 mm with 320x240 pixel resolution and up to 65 K colors. Usage of QVGA resolution in the at-the-frontier PDA line-up is a questionable step. The company decided to arm the screen with glare filter, which makes for matte shine of the display and thus dim and faded picture. But this drawback is fully compensated by the screens high brightness and the ability to adjust this parameter precisely.

Battery life

The handheld carries a 1200 mAh Lo-Ion battery onboard, which is par for the course for many PDA by various manufacturers. Though, it is quite another matter that in many models capacity like that allows getting only moderate or even sub-standard figures of battery life. Though the A686 doesnt fall flat on this front and even outdoes its already great sibling the A626. As the manufacturer claims, in the A686 this capacity will be enough for 15 hours of music playback with the screen switched off and 5-6 hours of GPS navigation.

Below are the results of our standard battery life tests.

Reading mode the least power-hungry mode of all. Display backlighting level is set to the minimum that makes for comfortable reading, then we launch Haali Reader and activate auto-scrolling.

MP3 mode self-explanatory test. Display backlighting gets switched off (in case with the P3400 it was set to the floor), volume level is set to the medium level, and then we link up the PDA with headphones and playback MP3-files with 128 Kbit/s bitrate via MortPlayer.

Maximum load Display brightness is set to maximum, thereupon with start up TCPMP player and initiate playback of 320x240 pixel movies.

The figures for Asus A686 are up to other ASUSTeK-branded PDAs and even take the bar a step above. Like other Asus PDAs the A686 has shown the best rates in each mode compared to the models by other manufacturers. Specifically, it lasts 5 hours at maximum load and more then a day (!) in reading mode. MP3 mode made the A686 switch off in 23 hours 47 minutes, which automatically makes it one of the best all-round performers in terms of battery life to date.


Asus A626 is powered by a 312 MHz Intel XScale PXA270 CPU. Out of 64Mb of RAM 54.05 Mb is user-manageable, which is enough to get most of the tasks completed. The size of the bundled flash-memory makes and 77.65 Mb, and is more then enough for installing and running the most essential applications. Vast majority of apps may be installed on the memory card.

We carried out a standard test with SPB Benchmark pack. In view of the fact, that the test does not give an objective picture of the performance of handhelds running WM 5.0, we have extracted only a few types of data from it. In terms of performance, the A686 is among the best in our chart.

Then the device was put through its paces in TCPMP benchmark. tested with Benchmark built n TCPMP video player. 100% performance means smooth film rendering without dropped frames, but with possible collapses during dynamic scenes. 120% and more ensure smooth playback without lags or dropped frames at all

It comes as no surprise that nothing has changed here since the A626, whose performance rates can be found in the respective review.


The device comes with all the wireless connectivity options you might need

As for Infrared-port, there is nothing to dwell upon.

The PDA has Bluetooth and Infrared connectivity options onboard, though Asus wasnt generous enough to arm the A686 with Wi-Fi. Probably it is due to the fact that if it actually had it, then it would impossible to set the A686 apart from the top of this line Asus A696.

The device comes equipped with miniUSB cable used for synchronization with PC as well as for data connections. The A686 makes use of a dated USB 1.1 protocol, which limits the data connection speed to 12 Mbit/s. In practice it will take from 30 to 40 seconds to upload a 10Mb file to the handhelds memory. For USB-connection the capability to use PDA as a card reader is provided. To make this possible, you should enable this option in the USB settings.

The device carries Bluetooth 2.0 module with EDR support onboard. The PDA comes installed with Broadcom (Widcom) drives, which is a good thing, as many latest-and-greatest PDAs are preloaded with Microsofts software, whose functionality is limited The number of profiles supported can make unprepared user tremble. The A686 contains all necessary profiles including A2DP (stereo sound to Bluetooth-headset).

When tested, the A686 brought about no Bluetooth-related issues. All profiles did well: Internet access via phone, synchronization with desktop PC, files and contacts beaming, Bluetooth keypad coupling. Driver version - 1.7.1. Build 9701

The list of supported profiles is as follows:

- A2DP-Source
-Generic Object Exchange


The device makes use of SiRF Star III GPS chip which is installed in most of communicators and handhelds these days. The chip is placed in the upper part of the casing. The cold start time makes 14 minutes, which is pretty much. It takes the A686 about 3-5 minutes to pick up the signal while on the streets. Though when we had it indoors, specifically 3 meters away from the window in a 5-level building, it spent about 20 minutes on getting online, but ultimately it managed to detect the signal and then didnt let it go.

We tested reception quality in car, moving around the center of Moscow. Take note that the device was always in my hands, thats where some inaccuracies come from.

The scale is 180 meters per 1cm. The route goes smoothly, in two places you may see how the line breaks.

Now we are zooming in to 110 meters breaks in the line become more apparent. The first lost of signal is caused on purpose - we just cover the casings upper part with hands for a few seconds, and this results in a 3-second long offline session for the A686.

Scale 55 meters. We are driving the car under the bridge, the signal is lost again. The device manages to reestablish connection in 50 seconds.

In both cases when signal is regained, the navigator slightly distorts your located during the first minute. The recorded track lines reveal this in the form of lines crossing the route. Generally speaking, navigation with the A686 is quite accurate. When moving in a car with an adequate application installed on the Asus A686 (TotTom Navigator, for example), the navigator binds the route with road, so that the driver wont deviations of a few or even a dozen of meters, since all of them will be smoothened by the application.

Now a couple of words on the sales package of the navigator apart from standard constituents, it includes car charger and car holder, which is quite natural, taking account of the devices main focus. Though these two widgets are nothing special just about any GPS-navigator or GPS-equipped PDA comes boxed with a holder like this.


The device runs on Windows Mobile 5.0 for Pocket PC. Standard applications this operating system comes loaded with are covered in our dedicated article. Dont forget, though, that this one is a PDA, meaning that it has no phone functions.

Now let us turn to the suite of applications pre-installed on the PDA, which is not big, to be honest. As most of other manufactures, Asus has decided not to modify what the OS already brings to the table with additions of their own.

Mode Switcher is a small app that proved to be of great help in practice. In fact, it does the same job as ALT+TAB combination on your desktop. If you remember, such combination is used to bring up menu to switch between active applications or programs. In Asus A626 everything is done in pretty much the same way with two modes at your disposal active applications or system programs and options. The former allows you to browse launched applications, while with the latter, you will be able to go back to Today screen, start up Windows Media Player and rotate the display.

This application has a dedicated button on the casing the last key on the right. Pressing it one time calls up a pop-up window, and after that, punching this button, you can select in the list the application you need, let the key go when an application is highlighted, and the A626 goes into it.

ASUS Status is a module used for displaying system status thumbnails on Today screen. In minimized state it is the A icon you see, tapping on it will bring up a window in the lower right corner, featuring system information: USB connection type, CPU work mode, backlighting level, memory volume and battery charge. Any of these items can be removed from the list if your wish.

Audio is here to enable you to adjust sound. Using it you will be able to tweak balance, 3D, Bass, Treble. Here you may also set up microphone sensitivity during recording as well as record modes themselves.


By and large the conclusion on the new range of Asus PDAs is quite moot. This line-up almost doesnt improve upon its predecessor, sporting only subtle design-related tweaks. Functionality-wise these two ranges are no different either. The A686 carries the same QVGA-display and PXA270312 MHz CPU onboard. The main and, well, the only advantage of handhelds by Asus is supreme battery life in this sense Asus is still out of competition.

The model will best fit people looking for a basic car GPS-navigator. Of course, SiRF Star III chip does not provide altogether brilliant positioning for Asus A686, yet it copes with the essentials. The face-off between a GPS-navigator and GPS-enabled PDA is always won by the latter, thanks to its enhanced functionality an ability to choose navigation software.

There is still no word on the handhelds price, though you should expect less that 350-400-dollar worth price tag. Within at least this price-bracket the A686 has quite a lot of rivals that dont necessarily match it in terms of feature-pack.

Its closest rival has to be HTC Galaxy platform and Qtek 100 that is based on it. Price under 350 USD mark, pocketable size and Wi-Fi onboard speak in favor of the latter. Thus much like Asus A626 the very decisive role for the A686 will be played by its pricing policy.
