The Sony Ericsson Xperia Mini Pro features a 1200mAh battery, which is the same as in the Xperia Mini and at the lower end of what we'd expect to find in a modern smartphone.
Sony Ericsson itself rates the battery as good for up to five hours and 40 minutes of talk time, or around 330 to 340 minutes of standby time.
In the real world, obviously the Xperia Mini Pro has a smaller screen to power then most, and that is reflected in its battery performance. We managed a good two days of light use from one charge, with the phone also easily surviving for a full day of pretty heavy web, Twitter and camera action.
You'll still need to be careful if you're planning on going too far away from the comforting hum of the national grid, but the Sony Ericsson Xperia Mini Pro is unlikely to let you down.
In standby mode, with GPS switched off, it barely registers any power drain at all over the course of a few hours.
Internally, the Sony Ericsson Xperia Mini Pro supports sharing media via its Connected Devices DLNA app, which is a simple tool to turn the phone into a media server via a Wi-Fi internet connection. This worked well, with the smartphone easily pairing with another DLNA mobile in a few seconds.
Plus, as with all modern Android phones on a decent version of the operating system, the Sony Ericsson Xperia Mini Pro can be turned into a portable Wi-Fi hotspot or used as a tethered USB modem, which is ideal for hooking a laptop into the 3G network.
