So this morning I played a game on my iPhone X, for about 10 minutes it dropped down to about 98 percent battery, I left it idle for about the last 5 hours and it has dropped 7 percent in that time? Is this normal?

My battery is at 97%

If you device was still turned on, yes, it is normal. Even when not using it you phone “barks” at your local towers so they know where it is. It checks mail and just remains ready for use. All this takes some power.

7% is 5 hours is quite normal. Just relax and enjoy your phone. Apple put a lot of technology in it so we do not have to worry.

It won’t happen with X on iOS 11 or XS on iOS 12. But all old devices are having this issue on iOS 12.

On iOS 11 my device drain would be 0-1% in 4-5 hrs.

This is not true. I’ve had this happen with every device and operating system you have mentioned. I usually drop a good 12% on average from when I go to bed at night to when I wake up in the morning. The XS Max has been the worst I’ve seen so far. I lost 20% on average the last week or two while I slept.

All? Not really...No battery drain on a 8plus here running 12.0.1 same when it was on 12.0

Drain will depend on what app is running in background. How often it fires up the radios and gps to report your location, status, updates for notifications.

Drain rate will also depend on loactions from and signal strength to cell towers and/or the WiFi base station. If the iphone radios crank up signal strength you get more drain.

Some apps like facebook are notorious for battery drain even when you have them supposedly turned off.

So comparisons between users becomes meaningless. If you are loosing like 50% overnight then either app is hung up or battery is going bad. 1% vs 4% vs 7% is not really valid test when so many variables are in play.

What you could do is fully charge then put in airplane mode and don’t turn on screen. Overnight there should be very little loss if phone and battery are ok.

Yes. There is drain, you haven't measured it yet.

Charge it to say 70% and leave it on standby overnight. If all 8 hrs you're at 69/70, what you're saying is correct. Else you are wrong.

If you have poor cell service it will increase the battery drain. Quite predictable when I sleep in known place with poor reception, it can mean 20-25% increase overnight when reception is really poor.

Nope. It won’t drain on the XS or XS Max. Not right now at least when they are so new.

When I got my X in April, my battery drain would be 0% over 8-10+ hrs. Not it is easily 10-15% on iOS 12. Same reception, same signal, everything same.

I’m sure a XS won’t drain more than 1% on iOS 12.0.1. As the XS reaches 12.4 it will probably start draining 3-5%. By iOS 13 even more.

Sorry to not agree. But if I leave my MAX on overnight where there is poor reception, it WILL decrease the battery without a doubt. This is not theory, it is fact. It has happened multiple time and is quite predictable.
