Sony Ericsson Xperia X10 Mini Pro review
The Sony Ericsson Xperia X10 Mini Pro is the smallest Android phone to date with a QWERTY keyboard. We take a look to see how it measures up against the big boys.

The Sony Ericsson Xperia X10 Mini Pro is fine as a phone, but fails as a business-friendly smartphone. Everything is too small, especially the keyboard, screen and battery. We wanted to like it, but just didn’t. If there was a half star option, we would bump it up to 2.5, but there’s not...

Sony Ericsson has packed a Qualcomm MSM7227 600MHz processor in the Xperia X10 Mini Pro, which does well to keep up, although that's to be expected when there's only a small screen to power.
The same can't be said for the battery life of the device though. For some reason (probably space issues) Sony Ericsson has only packed in a paltry 930mAh battery pack, which will not keep your device running all day at all. Sony Ericsson quotes 3.5 hours talk time on the X10 Mini Pro, which is certainly not enough to keep in contact with people all day if you're going to use the phone for business purposes.
Sure, we may have got used to charging a smartphone once a day, but not twice in an eight hour working day.
This is especially poor when you consider the connectivity options packed into the device.
As you'd expect from a functioning smartphone, there's Wi-Fi 802.11b/g, HSUPA, Bluetooth and A-GPS to support the Wisepilot app (or Google Maps).
All of these drain the battery even more than just receiving a couple of push emails on the go and making phone calls. So be sure to turn them all off when not in use, otherwise you could find the battery draining before you've even got to work.
The Sony Ericsson Xperia X10 Mini Pro may be a smartphone, but it does feel like a toy.
If you're looking for something tiny, that will just slide into your pocket, great. Even better if you just want a device to talk on and occasionally send texts/emails.
If you want a fully functioning business device, look elsewhere, because this is just not polished enough to carry out any business functions well, especially if you want to keep the phone going all day without charging.
Verdict
The Sony Ericsson Xperia X10 Mini Pro is fine as a phone, but fails as a business-friendly smartphone. Everything is too small, especially the keyboard, screen and battery. We wanted to like it, but just didn’t. If there was a half star option, we would bump it up to 2.5, but there’s not...
