The Panasonic X400 is a classic feature phone that was introduced in the second quarter of 2004. Known for its compact design and basic functionality, the X400 was a popular choice during its time for users seeking simplicity and reliability in mobile communication. Though it has been discontinued, its specifications and features provide insight into early mobile technology trends.
The Panasonic X400 boasts a compact and lightweight form factor with dimensions of 84 x 47 x 17 mm, making it a highly pocketable device. Weighing just 84 grams, it was easy to carry around without causing discomfort. The phone was available in three colors: Black, Red, and White, catering to different aesthetic preferences. It sported a mini-SIM slot, which was standard at the time.
Equipped with a TFT display capable of rendering 65K colors, the X400 provided a modest visual experience suitable for basic tasks. The screen resolution was 128 x 128 pixels with a square aspect ratio, typical for feature phones of that era. Although it didn't offer a large display, its screen was adequate for viewing contacts, messages, and basic graphics.
The X400 featured a VGA camera with a resolution of 0.3 megapixels, providing simple photography options for users. While it wasn't suitable for high-quality photography, it was sufficient for capturing quick snapshots. The device did not support video recording, highlighting its focus on basic imaging.
Powering the Panasonic X400 was a removable Li-Ion 600 mAh battery, which was a common capacity for phones at the time. This battery offered ample standby time of up to 210 hours and talk time of up to 4 hours and 30 minutes, allowing users to stay connected without frequent recharges. The removable nature of the battery also made it easy to replace when needed.
The X400 supported GSM technology operating on 900/1800 bands, ensuring compatibility with global mobile networks that were widely used in 2004. It featured GPRS Class 8 for data transfer, although it did not support EDGE technology. Connectivity options were limited to an infrared port, with no support for Bluetooth, WLAN, or USB connections, which restricted data sharing capabilities.
The device lacked a loudspeaker and a 3.5mm headphone jack, which limited audio options to its downloadable polyphonic ringtones and vibration alerts. This was suitable for basic call and message alerts, aligning with its focus as a feature phone rather than a multimedia device.
The Panasonic X400 did not include a memory card slot, which meant users had to rely on its internal storage for contacts and messages. It featured a phonebook capacity of 300 entries with photo call options and maintained call records for 10 dialed, 10 received, and 10 missed calls. Despite its limited storage, these features were sufficient for the device’s intended use.
As a feature phone, the X400 operated on a proprietary system designed for basic telephony and messaging functions. It supported SMS and MMS messaging, providing essential communication tools. The inclusion of a WAP 2.0/xHTML browser allowed for very basic internet access, a useful feature for staying informed on the go.
Although the X400 was limited in some areas, it included a few notable features such as a Java-based platform that could run lightweight applications and games, including a simple game called MobileGolf. However, the limited processing power and memory constrained its capability to run more demanding applications.
The Panasonic X400 remains a symbol of the early 2000s feature phone era, reflecting the simplicity and reliability valued during that time. Its modest set of features and essential functionalities catered to users who required straightforward communication without the complexities of modern smartphones. Despite its discontinuation, the X400 is remembered for its durability and user-friendly design, offering a glimpse into the past of mobile technology development.
