iPhone 11 Is it normal for the iphone 11 to turn off when battery level is at 5%?

Hi
Just bought a brand new iphone 11 from apple.com and i noticed as i was playing around with the volume bottons and noticed the phone had shut off. I turned it back on and it had 5% battery left which i expected as i was monitoring the battery level before that and i could use the phone for a while after that without charging.

I knew the battery was low around 5-6 percent before it tunred off, Is that the reason the phone turned off? because i thought the iphone would turn off when the battery level is at 1%...
Is there any way to know what caused the phone to turn off?

The phone will turn off sometime before the battery is dead. There is no way for you to know.

The battery still had 5% left. even when i turned it on showed 5% and i could keep using it for another 20 min or so without charging or anything.

Never seen that happen with a new phone (new battery). The behavior is more typical of aged batteries.

Let the battery go through a couple of cycles and then check the heath in Settings->Battery. Also long term avoid discharging the battery too deeply on a regular basis (say below 20%).

Battery health is 100% as it's a brand new phone

If it continues to be 100% after a few cycles put in then everything is probably fine, and it might have been a calibration issue. After you have used it for a little while you can try connecting (via USB) to CoconutBattery on a Mac and see how it is doing.

Each cycle has to be fully charged or what? i'm not sure what you mean by a few cycles

Not necessary to fully discharge. For example, if you discharge to 50% and then charge to 100%, that's half a cycle. If you do that twice, that's one cycle.

If you discharge to 1% and then charge to 100% that's one cycle, but if you do that too often your battery will die more quickly (you'll get fewer usable cycles).

Never had mine die before they showed 1%. Maybe something intensive was running that the low battery didn't like?

i was not running anything at all. just playing around with the volume buttons and the sleep/wake button.
