My phone charger keeps going on and off?
So I have used a lot of chargers and they do the same thing but I have a iphone 7 and awhile ago I lost my charger that came with the phone so I went out to get a new one multiple times but I use my phone a lot so I have to use my charger a lot and I often find myself having to twist the charger now for it to even work but it looks like the chip is burnt out but I literally just got it and have only used it 10 times max through a span of 7 days. I'm not sure what the total problem overall is but if you can answer my problem that will help and if you have any charger recommendations that would help.
Added (1). The question is why does it keep going on and off
Ok… And the question is… What…
What does a burnt out chip look like? I use android phones and I replace the charger cord every few weeks if the connection gets unreliable.
I think the JACK of charging on the phone is BAD.
usually soldering trouble on its base and pcb 
One of mine did this too. Its just wear and tear. You need a new charger

- My iPhone keeps turning on and off like it turns on and off. Can someone tell me? Okay tbms it turns on and off on and off and then sometimes it shows a red screen for a few seconds then off again and dies out. It's not the battery because I got that changed thinking that it was the cause and it wasn't. So is there anything someone can help me with? The repair guy tried restoring it through iTunes he said it didn't work either it just won't come on it doesn't go pass the Apple logo before shutting off and on again and dying out
- My Internet keeps going off and then back on? I'm not much for computer things, but I have a computer, iPod, iPad, and iPhone. And the Wi-Fi on all of them keeps turning off for about 10-15 minutes and then comes back on. I tried calling Comcast, which is what we use, and they were only trying to charge us for things that didn't sound necessary. So what should I do? Or better yet, what can I do?
