Put it on charge last night, maxxed out at 92%. Suspecting something wasn't right, I ran a Battery Calibration app which deleted a file related to the battery's history/properties and now I've been using it for a few hours with WiFi on, and have 70% battery life remaining. Much better!

I recommend everyone with an Android try calibrating their battery at least once after you've cycled it a few times from new (leave it on charge for ages the first few times, even if it reads 100%). It certainly won't do any harm, and you might just be surprised at the results.
