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?
