I managed to get 4 hours SOT with 1h on tos, 30min on coc and left 8% juice. Wifi on almost all the time except sleeping time i put the device in airplane mode. Initially the battery drain are real.. but now seems like doing great. Last time i only managed to get 3 and 1/2 hours SOT at most...

Battery seems ok to me. When doing live recording the sound is very soft on playback. When I turn on NFC, I have to turn on bluetooth to connect to my speaker, that's a bit annoying.

lollipop drain battery kaw kaw.
there was one time i just left my ZR idle, battery drop 15% in 30min and it is hot.
But i like the ultra stamina mode though

Anyone can recommend me any guide to root this phone?
I've tried once but fail.
Really need to root as my internal memory is running low. Need to move my apps to SD card.

Isnt the current OS have the ability to move app to sd?

Can't even install the latest update as there is no enough space. Tried to remove all the unimportant stuffs but still can't free 1.2GB

Uninstall some unessential apps, update, then reinstall them back. And yeah, check photos/audio/video file in internal memory, those are usually overlooked, especially photo thumbnails. There's also folder called 7zlogs, you can delete those too.

Thanks bro.. will give it a try

I just broke my ZR screen, Sony centre said cannot fix, need to replace the whole unit.
Any idea where can fix it?

If official place cant do it, your best hope would be 3rd party phone shops. Although my friend DIY with e-bay bought spare parts.
