The battery on my iPhone 16 Pro Max is dranning quickly.

Some apps drain more of your iPhone's battery than others, and it's no surprise that the biggest offenders are those that track location, stream video or generate graphics (games, for example, especially fast-paced online ones)

If you are facing this then turn Low Power Mode can reduce battery drain.

And also disable most of the most useful functions of the iPhone.

Please define “quickly”.

If you charge an iPhone overnight, every night (a best practice) it should not need charging until the next night unless you are a very heavy gamer. If it fits this profile it is working as intended.

I’m not gaming just using my phone like normal people still battery drain , iPhone 16 should have best battery but it’s not unfortunately

Again, what is “quickly”? Does it drain in an hour? 2 hours? 5 hours? 10 hours? 24 hours?

And what are you comparing it to?
