Blurry images of a thin-bezel Xperia appear, along with battery life screenshots from Sony Sirius

It's no secret that a Sony Z1 refresh is coming, under the Xperia D6503 'Sirius' moniker, but the code number D6603 has also popped up here and there, indicating Sony has more flagships in the pipeline, and this design might belong to the latter. 

Meanwhile, а few screenshots, claimed to be from the upcoming Sirius, appeared over at the dedicated XDA-Devs threads. These show the battery life reports from the phone, which is said to carry a generous 3300 mAh capacity unit. Judging from the battery screens, endurance is on the average side, but these are probably taken from a preproduction unit, so we wouldn't read too much into them.
