New battery causing phone to be slow under 10%

So I recently decided to put a new battery in my IPhone 6s Plus as the old one wasn’t holding charge. I ordered a battery from another source and installed it. However, when my phone would get below 10% battery remaining, it would become very slow. As soon as I would plug it in it would work like normal. I figured this would be from a inferior battery, so I ordered one from iFixit. However, the new battery does the exact same thing. Does anyone know why I’m experiencing this and how to fix it?

Answer this question I have this problem too

Is this a good question?

No, I’m not turning on low power mode. As soon as my phone gets below 10% battery, it becomes very laggy and unusable until I plug it back in. This didn’t happen with my old battery

Sorry, I never found an answer. Just living with it as it only happens when the battery is low. I'm sure there is an answer out there somewhere but I haven't found it yet.

Replace it again, if the problem persists, feel free to tag me in a reply that you have tried the part, because we could possibly be looking at something super fun :)

Are you able to get me a very close picture of the battery connector on the logic board of the phone?
