Anyone feel like the ifixit replacement isn’t that much better than the old iPhone battery? I recently replaced my 2 year old iPhone 6 battery and it doesn’t seem to last any longer.

This is gonna be dependent on a few things. Where did you get the battery? Like they said, are you using after market/car chargers? How often are you on your phone? I literally just replaced the battery on my 6S two days ago. Yesterday I was constantly on my phone. The entire day! Was the battery life good? Not really. Had to charge it in the middle of the day
