I've just encountered a problem that is puzzling me. I've had my T5i for about 8 months now, and it was working well. Just last week I noticed that if I do not turn the camera off when I am done using it for a while, it doesn't go into stand by mode (as it used to) and my batteries are drained when I pull it out of the bag for another shoot.
I am using fresh Canon batteries so they are not the problem. Again, this only started to develop a week ago, but because I am a travel writer and often forget to turn off the camera when I am going from scene to scene, this is so very annoying. I've missed some great photos because I have to change the battery!
I don't recall changing any setting. Should I go through the hassle of sending back the camera for service, or is there a simple fix? Thank you for any advice you can give me.
