I have a Vodafone SIM card in an Android phone. In that phone, there is a 2000 mAh battery. I had noticed that the battery was discharging very fast, about 2%/hour when idle!
At that time, no battery consuming apps were running and all other mobile radios were switched off.
The discharge rate should have been less than 1%/hour.

I thought that this might be a problem with the battery, but when I tested with another Vodafone SIM card, I saw that the discharge rate has again gone down to 1%/hour!

Can anybody say what is actually happening?

Additional information: Few days ago, accidentally, there had been a half-hole on the SIM card. So, is the problem due to this hole?

    How old is the SIM card? The required power voltage of SIM cards has AFAIK changed over the years. Therefore older SIMs need more voltage and usually more power. – Robert Mar 28 at 18:52
  • No, that was relatively a newer SIM card. – Puspam Mar 29 at 2:59
