Got my iPhone SE (bought mid-2016) simply swapped for a new one yesterday as they said they had issues when trying to open it up, which was a result - whole process was around two hours from dropping off to being available to pick up.
Got mine done a couple of weeks back. Not sure what difference it’s made but feels anecdotally as if the battery lasts longer when not being used. Don’t feel like I have to have the phone constantly on charge.
Just over three weeks to get your battery replaced for £25...back up to £45 in January.
