| Mini Review of the Siemens SL55 | 
|   | I have just been given the chance to try a Seimens SL55, courtesy of Howard Forums member carsmovies. Despite the very similar number, the SL55 is a very different phone from the S55, at least in terms of physical appearance and size. There seemed to be quite a few similarities in functionality, but I didn’t have both phones handy. Last Updated: 27-Sep-2003 |

General
I haven’t been particularly fond of any 
Seimens phones I’ve tested in the past, but right up front I’ve got to tell you 
that I was very impressed with the SL55. Before we get into the reasons why I 
liked it so much, let’s have a look at a few details about this model.
The way in which this phone hides its keypad is rather unique (in that I don’t 
know of any other phone that is built this way). Imagine a small phone that is 
made in two halves (a top half and a bottom half). These two halves slide up and 
down relative to one another, thus exposing the keypad and making the phone a 
bit longer when in use. The two photographs seen at the top of this review 
should give you some idea of how this works.
The phone is quite small when closed, measuring just 3.2 inches tall, 1.75 
inches wide, and 0.86 inches deep. It tips the scales at a light 2.8 ounces (79 
grams). It supports 1900 MHz, 900 MHz, and 1800 MHz (but not 850 MHz 
unfortunately). The phone comes with a rather small-capacity 500 mAh battery, 
but according carsmovies, the standby and talk times are quite reasonable.
The beautifully rounded contours around the earpiece make the phone extremely 
comfortable against your ear, and carrying on prolonged conversations will 
likely be a joy with this model.
The screen isn’t particularly large, and it sports only 4,096 colors, but unlike 
the ghastly black holes on Sony-Ericsson phones, this one is actually viewable 
without the backlight. In bright sunlight the display is very easy to see, and 
the brighter the sun, the better it looks. While the display wasn’t the greatest 
I’ve ever seen, it was bright, sharp, and readable under virtually any 
conditions.
The color screen is always visible, as are a few of the important navigation 
keys. It is therefore possible to operate the phone without opening it, assuming 
you don’t need to get at the numeric keys. Those keys are not especially well 
designed though, as the navigation keys feel loose (they have too much play) and 
the top row of numeric keys is difficult to get to, since they sit just below 
the top half the phone when you slide it open.
The phone also includes quite a few features, including Java apps, calendar, 
alarm clock, stopwatch, calculator, picture messaging, EMS, MMS, voice dialing, 
WAP 1.2.1, class 8 GPRS, IR port, polyphonic ringtones, games, and 
synchronization with Microsoft Outlook. It does not include Bluetooth.
RF Performance and Audio Quality
The really great news is HOW this phone 
works. We’ll begin with the RF performance, which is excellent. Although it 
doesn’t quite match the performance of my Nokia 6310i, the difference between 
the two phones is marginal at best. After testing so many phones with lackluster 
RF characteristics, it’s refreshing to find one that can really hold its own.
Audio quality is among the best I’ve heard. It has a bit more low end than the 
6310i, but it is otherwise remarkable similar in tonal balance and overall sound 
reproduction. To its credit, it has virtually no background hiss or other 
extraneous noises, and to that end it is slightly better than the 6310i. 
Outgoing audio is equally inspiring.
Audio volume is good-and-loud, and a match for the 6310i. However, carsmovies 
informed me that the SL55 has a volume-boost feature (like Nokia), but that it 
kicks in quite early. He was certain that in the noisy conditions over at Square 
One the volume boost would have been in effect. I knew that the boost wasn’t 
quite so easily triggered on the 6310i, and so it might not have been in effect 
on the Nokia. If that was the case, then the Nokia is a slightly louder phone. 
If the Nokia was boosting audio levels at that time, then the phones are 
virtually tied in this aspect.
I’m not about to sell my Nokia 6310i and buy an SL55, but if I had to replace my 
6310i tomorrow (because it was lost, stolen, or broken) then I would give 
serious consideration to buying an SL55. This is rather expensive phone however, 
in a sea of other models with great feature sets (like the Nokia 3650). However, 
this is a much smaller phone, with nice styling, and unique slide that should 
make you the center of attention (if that sort of things turns you on).
