Iphone 6s - Plugged into power and starts charging. It sometimes charge and sometimes randomly stops charging. In that case, I only switched-off wall power button and upon switching-on, phone starts charging. Nothing change, no loose connection, no cable re-insert, only wall button off/on works. How phone is behaving like this, is there any problem ???

I would say that when troubleshooting charging issues, I would do the following (in order): Always try another Lightning cable and charger, preferably Apple original or MFi certified units.The Lightning cable 8-pin connector should be sitting flush with the housing and completely inserted. If it is not, there could be lint/dust/debris inside the port impeding a proper connection. You can clean it out with fine point tweezers or a dental pick. Just be careful not to damage the pins inside the Lightning Port.Change the battery. The battery is the weakest link in the entire phone and certainly for charger related issues. It is also the easiest thing to replace. Use a battery utility, such as coconutBattery (for Mac) or 3uTools (for Windows) to test the battery prior to removal. Anything less than 70% of design capacity will require replacement.If the battery is in good condition, you can use a USB Ammeter to determine if the phone is really drawing current when it says it’s charging. If it isn’t drawing current, then I would change the Lightning/Charge Port.If a new battery and charge port still don’t resolve the issue, then you either have faulty replacement parts (possible) or a logic board issue.

If you have iPhone 6s Plugged and Stop Charging after Random Time then simple solutions is that remove dirt from your charging port iOS device.
