when i charge my phone and use it at the same time the battery percentage is not increasing. it only increases if i dont use it and i have even replaced the battery and change charger and its doing the same thing. it will just stay on 1% whilstusing

What are you using to charge? If you're using about the same current as the power adapter can supply, then it will hover around the same charge level. If you use something like a 12W iPad power adapter, it will almost always result in positive charge level no matter what you're doing.

I am currently using an normal iPhone charger not a iPad one. Are you sure it’s to do with the power of the charger?

Yes. I've used a lighter-plug power adapter rated at 700 mA. When I tried using that to operate my iPhone 7 while using Apple Maps the charge level would slowly go down. If you really want to use it while running apps that use substantial power while increasing the charge level, you're going to need something more than just the adapter that came in the box. That's OK if you're charging it overnight and not actively using the phone.

Yes, very well known issue. The 1watt iPhone power supply cannot provide enough power to charge and actively use on some newer iPhones. Especially if using them for anything intensive like a game.

1 watt?

Typo - 1 amp (DoH 😊 )
