Oh ok once its approved just check. Because my phone was work well till last month. But suddenly battery drain so fast its so impossible. But this WiFi problem I don't know why both phones showing same way. For my phones I just allowed whatsapp and Gmail to run even my stamina mode is on. I used that way since 2013.

For what I see on that last screenshot that you have really bad network coverage. 

[amd_2012]

Yes because for my room 4g signals are really low. But I turn off my 4g I will get good hspa+ network. With full coverage. I will show you the screen shot next time. since 2013 my 4g coverage was like that. When I brought my Xperia z1 2013 my battery drain was just 2% for 8 hour sleeping standby mode. But after lollipop it was just 5%. But now from last month its 15%. I will update with more screen shot.

Hi Sony

My z1 have this problem. After 25% my battery drain super fast. And 15% suddenly phone is off that don't have battery life. so when I use power+volume up button and rest the phone that problem not happen. But if I do like that my stamina mode not working properly. If I do that again then 15% my phone suddenly shut down. I did pcc software repair. But I don't know why its happening. Please tell me how to calibrate battery or fix this problem. Please Sony
