-often displays notifiacation data traffic disabled( it was always turned off)

-going to options to change mobile operater the mobile rebots

1. Elaborate on battery life

2 and 3. it seems that you need to replace your SIM card.

I am traying with another card, but makes no sense of resolving this problem.

how come the sim card will manifest on battery energy and phone rebots?

You have poor network coverage, but that's a huge drop on your battery, take it to a Sony repair center, also repair it with SUS or PCC, you might have to replace the battery, a faulty SIM card could explain the constant reboots but this could also mean an issue with the motherboard. 

Update Service (SUS)

PC Companion (PCC)

Bridge (for Mac)

Tryed with other sim card last night and there was same thing, but after instaling update center and updating on android 4
