Why did my IPhone battery go so quickly?

I have an IPhone 7 plus, I've had it for less than 2 years, and the battery has completely went. It doesn't turn on and it says its been charging for the past two years. I know people who have have the same IPhone for several years and doesn't give them a problem but mine is complete garbage.

Added (1). Spending $700+ on a phone it should last

Sometimes it's just that you have bad luck. It happens. Deal with it.

Call apple for it

Have the battery replaced.

They do go bad, you know…

  • Why does my iPhone battery drain so quickly? I have had an iPhone 4s for almost 2 years. The phone has slowed down a lot since that time and the battery is drained extremely quikly, even when I'm not doing anything. If I just listen to music for 40 mins, doing nothing else, with a locked screen, my battery will go down 20%. It's insane. I never overcharge my phone. I charge it to 100% before I go to sleep and when I wake up its around 96% @ WB, No, even with everything closed it, the battery still leaks.
  • Why does my iPhone battery die so quickly? I had my iPhone for about a year and a half, and recently I've noticed that the battery is draining incredibly fast. I've always had it on 3g internet/Wi-Fi and the battery never died this fast so I don't know what the exact problem is. I charged it to 100% yesterday and I only used it for maybe about 10 minutes and left it untouched for the rest of the night. Today when I woke up the phone was dead. I haven't changed the settings or anything fyi.
  • Why does my iPhone 5s battery drain so quickly? I would charge my phone till 100% and stop charging for at least 6 hours. It's on airplane mode and the Wi-Fi isn't on, but after 6 hours without using, the battery becomes 7%. My battery skips the %, from 100%, within 10 minutes of usage, it drops till 25%. Do I need to replace a new battery? Any tips to prevent this from happening after I change the battery?
