I've recently put a mirror screen cover on my iPhone 3G. Since then I've noticed that the battery life has decreased significantly. I've also noticed that the signal became a bit weaker. Is there a correlation or is something else the culprit ?
On my iPhone, I always have wifi, 3g and cellular data network all disabled. I guess the only protocol which is running is GSM.
I would remove the screen cover and check if things came back to normal, however, if I were wrong then I will have wasted my screen cover. Therefore, please advise.
