How we test landline cordless phones


Landline cordless phones continue to be an important communication option for many homes and our testers find out which models work best for sound quality, ease of use and answering machine.

Our expert testers

All models are tested with an extra handset. Models that are only available as a single handset are tested using an additional handset of the same model or brand. Answering machine performance is scored and shown in the table, but does not contribute to overall score. This allows direct comparisons to be made between landline phones with and without an answering machine.

How we choose what we test

Models chosen for testing include the most popular landline phones based on past sales as well as new models as they hit the stores. The most dominant brands in the Australian market are Panasonic and Uniden, with these two companies producing a wide variety of models with different features and functions. When we find a model that is widely available we include it in our test.

How we test

Ease of use

Our tester considers factors such as quality of the instruction manual, feel and comfort of the handset, whether the screen is easy to read and any other special features.

Sound quality

A panel of users receives calls in a quiet environment and assesses speech clarity, speech loudness, line noise and background noise on each model. Sound quality is assessed for receiving and making a call.

Battery life

We time how long each phone takes to fully discharge on talk and also record the claimed standby time. For the battery test we assess the talk time. After fully charging each phone's battery, our testers set the phones to talk, and record how long each takes to be discharged. A perfect score of 100% is awarded to a model operating after 24 hours.

Maximum volume measurements

Volume levels are are measured using a decibel meter, placed one metre horizontally away from the base of the phone. We measure the volume of the handset and base ringer, the speaker in the handset and the earpiece.

Answering machine score

Our tester looks at ease of use and set up when creating a message and managing calls, as well as sound clarity and quality for the machine message and the caller message.

Scoring

The overall score is made up of sound quality: receiving sound quality (20%) and sending sound quality (20%); ease of use (40%) and battery life (20%). Charging times are rounded to the nearest 30 minutes.
