Fantastic thank you

### ⭐⭐⭐ Hasn’t made a difference.
*by J***4 on 5 July 2024*

I bought this as my battery life was painfully bad. This battery has made absolutely zero difference despite my old battery health being 80%. I’ve also found my phone to be slower. And keeps freezing since changing it. Nor sure why.
