However still the basics has been covered on the phone. Battery lasts all day which was better than the Iphone 5 I had before. The positives, the OS is snappy, display is great and its waterproof. Two-Three months ago got the Xperia Z1, however after much frustrations with call quality with the Nokia 1020. Lots of great ideas that are not fully executed (USB port covers) audio jack on top that does not need cover to be waterproof but it fails too easily, not built for daily use. Also on waking up, the home screen has to redraw, much slower than when on older firmware. However, they added app info on top menu that does not allow you to not display (Sony Throw technology is always trying to connect and I want to disable it but cannot!) Now I have screens after screens of info that has to be individually opened to disabled. I like it that the record cover is the screen saver when I am listening to music. Last week, I downloaded the new firmware. Very frustrating that I have to use Bluetooth headphone instead of earbud during commute and exercise. That was last week, now when the headset wire moves too much it will also stop the music.

If I go in and restart the music it will come through the speaker so I have to unplug and replug the headset or earbud. This second Z1 is so finicky that if I touch the jack or wire it will stop the music. The audio port is finicky.both Z1 have had audio port problems.so bad that now I have to use Bluetooth headset. Finally, gave up and left the port uncovered, defeating the waterproof premise of the phone.

Or watch 2 hour movie (in airplane mode) and it only drains about 20% of the phone.The USB port covers fall out very often, I have replaced 2 in the past 2 months. Also I can listen with wired headphone on 5+ hour flight and it barely drains 15% of the battery. Battery life is great, I go 2-3 days before I need to recharge. On first Z1, it developed a gold halo on the edge that was 35-40% of the image. Life style changer!Camera and video works great if it is working. I had to give up talking while exercising, driving or multi-tasking. Also ear buds with microphones don't work that great either. However, don't try using speaker phone when driving or multi-tasking.the other end cannot understand or hear you. I like it that it has microSD slot (movies for flight and travel, ones not available on Netflix or Amazon).Call quality is good, like other phones I had in past. I use it all the time for sports activity with arm band. TMobile replaced with refurbished Z1 and this second one is less than 2 months old.The phone size and form factor is excellent. Disclaimer: this is second Z1 after the first one had problems before end of warranty.
