My iphone 6 loses battery even when i'm not using it, is this normal? - 1

Added (1). Last night i went to sleep, my phone was at 81% this morning i unlocked it and notice it was at 79%… Is this normal? Is anyone else having the same problem

Added (2). Up to now it has dropped 15% in
In usage: 1 hour, 30 minutes
Stand by: 5 hours, 55 minutes
Normal? Anyone?

Added (3). ***I don't have Wi-Fi nor cellular data on

Yes. It is totally normal.

In the iPhone there's a Bluetooth chip / a 3G / LTE chip / a Wi-Fi chip / a GPS Chip and so many other electronic that consume battery.

Now if all these, but the ones you use, are turned off then each full charge of the battery will last a longer time than you can imagine.

Do you use Bluetooth all the time?
Do you use Wi-Fi all the time?
Do you surf the internet using 3G / LTE all the time?
Do you have weak eyes (such that you need to keep the brightness turned all the way, up high?)

I suppose some of the answers to the above questions will be in the negative.

Turn off the options that you do not use.

Turn of Location Services polling.

Turn off Bluetooth when not being used.

Turn off Wi-Fi when not being used.

if you do all these meticulously, you will find that you have to charge the iPhone less number of times and that the battery will last longer and the phone will last you a few years.

Any device loses battery even when not being used. Completely normal. Losing 2% in several hours is nothing to complain about at all.

At the end of the day, the device is on, so that alone is using the battery.
