I bought this case and after i placed it on my 4s the signal dropped to almost nothing, battery started to heat up because i guess it kept on trying to get a signal and battery life went to crap again saw it drop from 90% to 75% in less then 45 minutes. Don't buy this case, i did read somewhere that if you remove the rubber around the case and replace with electrical tape the reception gets better. I have not yet tried this because i went back to the black ops.
