iPhone 6(S)/Plus Battery replacement performance increase?

[Strokee]

If I was to take advantage of Apple’s $29 battery replacement, how much can I reasonably expect it to improve the performance of my iPhone 6 Plus? Currently has some lag, stuttering and an issue where the ringtone volume doesn’t work (it just vibrates).

In theory - night and day. However I suspect from what I've seen here is that optimum improvement would be gained from a replacement battery followed by a total reset without restoring apps (to ensure no baggage is brought over).

Do you have iOS 11.3 or newer installed? Is the performance power management feature enabled?

Yes and no, respectively.

Well, if it's not enabled, then your phone isn't being throttled, in which case a new battery by itself won't really make much of a difference in terms of performance.

The biggest issue I’m having is the volume issue. A lot of times, with the ringer and notification volume turned up and enabled, the phone will just vibrate.

Not likely that something a new battery will help with, unless there's some hardware issue that is there and also gets fixed or you get a replacement device for some reason. If it's some sort of a software issue then perhaps a restore might be of some help.

In any of those scenarios, the whole power management throttling and battery health aren't really things that would relate to that.

The best thing battery replacement could bring you is extending the longevity of your device by a few more years. Performance wise, as stated by other members, won’t bring much improvement usually.
