Can a outdated iphone ruin a charger?

Recently my boyfriend and i both got a new iphone. Which i was excited about for my battery life to be better. Its been about a month since i got it and my battery life if horriabe still, remind you it's a iphone 8. My aunt has a iphone 5 and constantly used my charger. Is it possible since her phone is much older that is can ruin my charger? My boyfriend battery is perfect but mine drains so fast! I know it might sound dumb but i feel like it can be true?

No, all phones draw the same amount of electricity, the charger itself is rated from 1 to 3 volts maybe a little more and that is all a device can draw. It can't draw any more than that it will not harm the charger if the device you plugged in draws more than it is rated for, it will simply not charge.

For reference, I have an Iphone 3 and I have plugged it into many different charger bricks and they all charge it.

Check your usage. If you are constantly on your phone, using Wi-Fi your cellular data, streaming movies, playing games, surfing the internet, using Twitter checking Instagram, Facebook or even have the Bluetooth turned on these will drain your battery swiftly. While the battery life on phones is continually improving the way in which we use them can drain them quickly.

No idea I would be asking the company I got the phone from. I always get a new charger when I get a new phone.

Yes

  • Will the iPhone 4s become outdated soon? I'm an Android user that soon wants to switch to an iPhone. I've been hearing things about the iPhone 4 being outdated. Like updates or major gaming won't work on it. I'm planning on getting the iPhone 4s, but I'm worried it will soon too become outdated? Should I just pay the extra money for a 5?
  • Will my cheap iPhone charger from Amazon ruin my phone? I just got an iPhone charger that wasn't apple brand on Amazon for cheap. People are telling me that it isn't going to work or it will eventually start to ruin my phone. I just recently got an iPhone 5 too so I have no interest in having to buy a new one because the charger is going to ruin it. Will the things people keep telling me really happen?
