So prior to my phone completely not turning on or charging, I would occasionally get notifications that the charger was “not supported”. I cleaned the port and charger and still wouldn’t charge. I figured it was the connector port so i replaced it and still wont get any sort of charge. Could this be an issue with the battery? its been about three years since I last replaced it. Also read it could possible be the IC charging chip but still not sure. Any help is very appreciated
The charge circuit basically boils down to the charger & cable, the Lightning port, the battery and the various components involved in the charge circuit on the logic board. Are you using an Apple original or MFi certified charger and Lightning cable? If not, then try that first. If that doesn’t solve the problem and you have already tried a new Lightning connector, then use a battery utility, such as coconutBattery (for Mac) or 3uTools (for Windows). Once you get down to ~70% of design capacity, you’ve pretty much used up the best part of the battery’s lifespan and you should consider replacing it. If you have really low design capacity, that may be impeding the charge altogether. If you have access to a USB Ammeter, you could use that to determine if the phone is really drawing current when it says it’s charging. Finally, if it doesn’t appear to be charger, battery or Lightning port related, then you are left with a logic board issue and you should have an experienced micro-solderer look at your phone.
