hello i wanna ask you a problem with iphone 6s. so at this time my iphone 6s at the time of airplane mode there is a decrease in the percentage of the battery without me use. I’ve tried replacing the battery with a new one but it still happens. What should I do? is that a problem with ic? Thanks… need help… Update (03/03/2018) here I am uploading a battery percentage picture of my iphone. is this problematic with ic? Update (03/22/2018) The problem is in the original home button and that is not original, if we install the home button that is not original will get a problem in the savings on battery usage and your battery will quickly wasteful in standby condition. so advice from my original home button do not get damaged. Thank you

Hi! It is normal for the battery to drain even in airplane mode, as the phone is still powered on (although in sleep mode) waiting for the user input. Some apps and services are still running in the background further draining the battery. The only way to stop this is keeping the phone powered off.
