So I took my iPhone X into the local Apple store and asked them if it would be possible to change out my battery - according to my settings, I’m only getting 89% charge. Which is surprising to me, considering the phone is only 15 months old (or maybe this is normal?).

They strongly suggested that i NOT have it changed out (yet) ... and wait until it gets down down to 79~80%. Didn’t sound like they WOULDN’T do it, but they cautioned me not to just because of the risks involved, opening up the device.

Any opinions on this? I’m gonna have this particular phone for a while, and it would be nice to put a fresh battery in it, but not if I’m risking damaging the phone.

It's Apple. I would trust them with a battery replacement if it's free. If you're out of AppleCare then I would replace it when/if it becomes annoying (and turns off at 20%)

89% after 15 months is normal, at least if you charge your iPhone every day. I also wouldn't change a battery at this state – it still should last a full day, doesn't it?

Makes sense to replace to when it dips under 90%. But I would wait until end of the year. Aged batteries like yours normally won't be reliable under cold weather conditions.

I do charge it every day ... and no, I'm not having any issues. Just thought it would be a relatively cheap investment to keep my device going at max capacity for a while until I get a new phone down the road.

I got my X at release and had the battery replaced last year in December, just before the price went up from $29. It was at 89% at the time, and after 7-8 months the new one is back down to 96%. If I were at 89 % today I would pay the $75. I am sometimes away from a charger all day, and the extra hour of time was a lifesaver for me.

My iPhone X battery health is at 95% and I've had it for just about 2 years. Even used it for Uber and Lyft (so constantly on the charger) for a year. The phone gets charged every day.

Highly unlikely. When I had a new battery in my 3 year old iphone 6 it improved for about 2 months and was then nearly as awful as it was before (2-3 charges a day).
That sounds like really bad luck. The battery in my five year old iPhone 6 still shows 93% health and easily lasts a full day.

That's pretty impressive. I wonder why such a drastic difference compared to mine ... I know everyone's habits are different, but that's a huge difference.

I am thinking, from what I have read, that the replacement batteries are inferior to the original! They might be rated the same but they do not seem to last near as long!
Well, THAT sucks. Clever little move by Apple to make you think you're getting a fresh battery, when they're really just pushing you toward a new device. Typical Apple....

Are you asking about how it has a larger capacity than what it states? If so, it’s normal. It’s like cars, manufacturers claim x amount of horsepower in reality it’s more.
Ah ha, I see. Phew. Kudos.

I ended replacing the battery for my iPhone X back in December 2018. By that time it had a year and battery health was down to 88% with maybe 375-400 cycles. The new battery was installed on 12/28/2018 and today it shows 96% on the iPhone and 94% on Coconut Battery. however it went from 98% to 94% (Coconut Battery) in less than a month and about 30 charge cycles.

Same here. I'm more apt to hold on to this X as I'm pretty demanding on my phone and it's held up wonderfully so far.

My 6S Plus, even after Apple replaced the battery, on the other hand...

My wife has a launch X at 93%. It doesn't last as long, so I got her a battery case. Not bad after nearly 2 years. Proof that "babying" your battery is pointless.
