Wi-Fi and HSDPA make transferring pictures to the Web or sending them via email fast. You can browse the Web pretty snappily using the C905's browser or by downloading Opera Mini, which we prefer for full-page browsing.
Audio quality during calls was loud and clear, as was the loudspeaker. Stereo Bluetooth is available if you need to listen to music wirelessly and it works as expected. Unlike certain modern phones that come with tonnes of on-board memory, the C905 only has 160MB on-board, but you can upgrade via a Memory Stick Micro slot that can hold up to 8GB.
Battery life is quoted at 9 hours of talk time using GSM and 380 hours of standby time. On 3G it's 4 hours of talk time and 360 hours on standby. We found it lasted for over a day with moderate use but using of the flash, HSDPA and Wi-Fi drained the battery faster.
The Sony Ericsson C905 is one of the best camera phones we have ever used. Similar to the Nokia N82, it manages to take high quality photos and offer a plethora of other features as well. In this case, the camera phone is as good as a camera, which we find impressive considering most are nowhere close. One of its best traits, for instance, is its ability to handle low light so well, which many camera phones don't do. It's not a small phone but it will deliver, so we highly recommend it.
Update: This review was updated on 20 November with some minor points about the screen, MP3 player and radio. The score didn't change.
