As a mid-range 3G handset, the Sony Ericsson T715 puts in a decent power performance. Under optimum conditions the supplied 950mAh battery is reckoned by Sony Ericsson to deliver up to four hours talktime or 350 hours of standby on 3G networks (or 10 hours and 400 hours, respectively, in GSM-only coverage).
While it will vary on how you use the phone (such as whether you're hitting the music play button regularly), with our typical amounts of usage, we comfortably managed over three days between charges.
Organiser
A familiar batch of standard Sony Ericsson organiser functions and productivity tools come pre-loaded. There are few surprises with the calendar, calculator, tasks and notes functions – all are manageable and easy to use – while the package also contains timer, stopwatch and code memo apps.
We've seen them all before, and they work effectively enough. And you can synchronise contacts, calendar and notes with a remote service or Microsoft Exchange server via SyncML or Exchange ActiveSync.
