Part 1. Why iPhone Battery Drain
Have you tried doing an iPhone 14, iPhone 8 or iPhone 6 battery drain test? If you have, then afterward, you should have discovered the battery drains faster than before, there is undoubtedly a reason why this happens.
You can find various possible causes, but one of the first things you can speculate is because of too many apps running at the same time.

We recommend closing the ones you’re not using to save battery. However, some apps still run in the background even when closed. It’s up to you to save battery charge and erase the app or keep it while the battery drains more than usual.

And that doubles when you stream videos online, like on YouTube, Facebook, Netflix, TikTok, and more. If you don’t want them to take up too much of your battery life, you should reduce the time you reserve for using them.
