Sim causing fast phone discharge

Rhino666

I have a Tocco Lite 2 phone on contract at Orange/EE.
The phone only holds charge for 2 days. My girlfriend has exactly the same setup as me but hers holds charge for over a week.


After a lot of investigation we have found the problem - my sim. Swapped sims over and the position with phone charge holding reversed. I got a new sim but no improvement.


Girlfriend has an original Orange 3G sim with no micro option. My sims are Orange brought to you by EE with the micro option. We are in a poor reception area of South Devon.


Any ideas on this and does anyone know if I could lay my hands on an old Orange sim that could be used with my number.


Thanks


Rob
