iPhone will not power on and is not recognized by PC

My iPhone powered off suddenly while I was using the hotspot. The battery was not low when it powered off. Now it will not power on and is not recognized by my PC when plugged in with an OEM Lightning cable. I opened the phone and disconnected the battery, waited at least 10 seconds, then reconnected the battery and attempted to power on again. I tried this several times with no luck. I’m thinking that the battery needs to be replaced, but wanted to see what you guys think first.

Thanks!

@bomtomdabil yup, start with a new battery and then re-evaluate to see what is going on. If nothing else a new battery will give you a known-well starting point for further troubleshooting. iPhone 6s 电池更换

Hopefully you were not using non-original chargers/cables since those are known to destroy the charging circuitry on the logic board. Charging issues as well as non-booting issues can be related to the Tristar IC (U4500) which is all part of it. Again, start with a new battery and see what you get.

@oldturkey03 Thanks for your response. I just did a battery swap with a family member's iPhone 6S+ with the same results. It has, unfortunately, been used with non-original cables. Is there a way to quickly see if they have caused the problem, or would I need to replace the entire logic board to find out?

@bomtomdabil I figured something like that. I got a bunch with the same issues laying around. You can get a tristar tester like this ($$$) and check it out. Or, of course you can contact reputable sources like @refectio to see if he can help you out.
