I bought my wife an S3 recently. She uses her phone probably 25% as much as I use my iPhone 4 and yet her battery is dying within 24 hours.
I'm assuming its a battery issue and will see if Vodafone will give me a new battery under warranty - but after exhausting software efforts to conserve battery life have had no luck.
Was wondering if anybody else had any tips that might explain why this is chewing through so much power.
