Battery life of xperia zr?

[Shravan_sp]

I recently purchased a xperia zr and the battery life while the phone is idle is bad.
When I charge it to 100% and go to bed at 9 and wake up 5 in the morning the percentage shows only 73%.
Is it normal for a quad core phone or should I consider this?
* stamina mode is on
* Mobile data, Bluetooth, Wi-Fi, hotspot, nfs... is off

*I deleted that 'news and weather' widget.

Hi Shravan

How were you able to delete the News and Weather widget. Its a in-built feature. Did you root your mobile?. I tried everything except that and my battery has got better. but still it lasts only for a day max. if im not using wifi, mobile data, bluetooth etc. i have even disabled the show notifications for all the apps and still its the same. if i keep the phone in idle mode, for example the percentage was 90% when i kept it in idle mode. After 3 hours its around 79%. Don't know what to do. Can anyone help
