Have you replaced your iPhone battery, and was it worth it?

If battery health is the ONLY problem with your phone and it is in otherwise great shape then yes it will get you another 2-3 years out of your phone and apple typically supports full OS updates for 4-5 years. Again only if you are fully happy with your phones performance etc..

I got 4+ years out of my iPhone 7

Batteries are weird. Once they get into the 80s when it comes to maximum battery health/capacity they need to be replaced.

I had an older iPhone 8 battery replaced at a battery shop near me before I sold it and it allowed me to ask for another price. I’ve got an “older” iPhone 12 that I gave to my mom and I’m planning on passing it down to my little brother this year but before I do I’ll probably have the battery replaced. But this time I’ll have Apple do it. It’s possible to do it myself but the price to effort ratio isn’t there, especially since I care about keeping the water resistance.

I replaced the battery in my iPhone 6s+ when the phone was a few years old. It was like getting a new phone. I kept it as my daily until the 12 came out. The 6 still works fine, I use it for drone flights.

It’s worth it if you plan to keep your phone a few more years and notice either diminished life or performance.

Yes, and it works.

I would only replace it when the phone’s battery degrades such that performance becomes limited, unless you really need that extra juice during the day.

I did a battery swap on a four year old iPhone 11 Pro that did not make it through the day sometimes, despite battery health at 88%.

This did fix it, the phone feels like new. Did the swap at an Apple store, walk-in with appointment and wait two hours.

The battery health percentage is not an accurate health measure. My battery was done, even with showing 88%. The Genius guy told me the number of charging cycles is relevant as well, and he recommends a swap after 750 cycles. Mine was at around 800 cycles.

All in all: recommended.

Yes I've done it, absolutely worth it... but not at 86%. Wait until it drops town to 70-something. Make sure it's a genuine Apple battery - a lot of cheaper batteries are total garbage.

I suspect you have a software problem. What apps are using all your power? Can you configure those apps to use less?

Or maybe you're just too heavy of a user for your phone. The iPhone 13 Mini battery is about 10% larger and the CPU also uses less power. And larger iPhones are even better again.

Perhaps you should upgrade? Or you could buy Magsafe battery pack (the Apple one is better than third party ones - better software integration causes the phone to use less power while it's connected to the battery, which allows the battery to be smaller/lighter for the same benefit).

I'm wondering the same thing with 83% on my 12 mini, I've contemplated trying to get a 13 mini but I'm not sure if that's really worth the extra cost. (I wish there was like a 15 mini coming out as I would just hold out, but that seems like a lost cause)

Yes, and yes. I did this with an iphone 8, I think, which basically gave it a few more years of functionality before the advances to cameras and processors became too great to ignore. I used a kit from iFixit which was pretty easy to use.

FYI: I think the way to gauge your battery is to look up the number of charging cycles it has had. If it's over 1,000, that battery is past its operational lifetime.

I’m currently sitting on a 75% iPhone 7. Gonna run this sucka into the ground! Phone is solid outside of having to live within arms reach of a charger.

Fuck yeah its worth it. Changed the battery of an old 1st gen SE and gave it to a young family member. Perfect first phone, and i gave a new life to for under 30€.

I got a replacement just short of 2 years and it feels like I just got the latest model. I have an iPhone 13 and it feels like I got a little bump even though I’m just back at where I started.

I’ve not done it on any phone newer than an iPhone SE. It was worth it back then for sure!

I replaced the battery for an iPhone 6s after 3 years (75%) and it lasted another 3 years. I took it to an Apple Store.

I also purchased a kit from ifixit and replaced the battery on my daughter’s 6s. Wasn’t too difficult, but I do wish it was easier. Her phone lasted about 5 years.

In your case, I would assume that you're looking to actually use your iPhone 12 mini, after replacing the battery, as opposed to seeking out the actual trade-in value. Would it be worth it to you? Honestly, I suspect so. If you have a particular affinity for your mini, possibly because you just can't abide the larger form factors, then you're pretty much stuck with a 12 or 13 model, as there is no 14 mini and there almost certainly won't be a 15 mini; Apple has moved on from the smaller form factors. And given that an upgrade to a 13 would be a lot more money for a lot less relative value, I personally think you might reasonably find it worth the few dollars that it would cost to replace that battery.

Oh... but don't do it through Apple; do it through a reputable third-party. Way less expensive, and likely a lot faster.

Even if it’s prolongs just a year of life to the phone it’s really worth it. I got my XS battery replaced 1-1.5 years ago and I’m planning to upgrade this year. It went from charging 1-2 times during the day + at night to lasting full day almost every day.

I use an iPhone 8 Plus and replaced the battery twice at around 79%. The first was cheap—$29, I think, because Apple was caught throttling performance unbeknownst to users, so they had to make it cheap. The second upgrade was $49. Both def well worth it because performance & battery life were noticeably boosted, the phone still rocks, and it beats the hell out of having to buy a $1000+ every few years.

Changing your battery will add significantly to your phone’s life. I usually have the battery on my phones replaced at least once in its lifetime.

86% is a very suspicious number if you ask me. My launch day 12 Pro Max has been at 86% health for at least 6-8 months. My launch day Series 4 Apple Watch was at 86% health when I upgraded to the Ultra on launch day… if I had a tinfoil hat I’d probably want to know more about the meaning of 86%.

On every single iPhone I've owned in about the last 10 years. Usually around 18-24 months. It always makes a massive difference and makes the phone perform like new again. Totally worth it.

Changed mine in my previous iPhone 6. It went on for about 2 extra years when I finally updated to iPhone 12

Yes.

I replaced the one on my iPhone 6 myself and that helped tremendously.

I’ve had an iPhone 12 Pro since launch and I ended up getting a replacement from Apple last year when the back cracked so naturally the battery was replaced, it was at 89%, and the difference wasn’t as noticeable but my battery did last longer.

I had my battery replaced by Apple on my XS. I was down to about 80% life, maybe less. I have seen a very noticeable improvement in battery life. It seems to charge faster when I’m using it on a charger. And before I was losing like 40% of my battery overnight while my phone sat here. Now it’s maybe 2 or 3%.

If you go with Apple they also replace your speaker since it’s integrated or something? They also accidentally cracked my screen when replacing battery, so I got a new battery, new speaker, and brand new screen for like $80 or $90. Definitely breathed new life into my phone.

I have a 12, and I’m at 85% health. Don’t know the cycle count though. I plan get a new 15 later this year, replace the battery on the 12, and hand it down to another family member.

My 13 pro max is only a year old and at 91% health which kind of worries me. Battery life is still very good however. I’m afraid of getting reduced performance too. And if I skip this year’s iPhone I’ll likely be around 80% health by then which is probably going to suck

I replaced the battery of my iPhone 12 mini and I regret it. The battery health was at 83% but the phone wouldn't last 4 hours (not screen on time just 4 hours period).

I asked apple if this is expected and they said no and that my battery cycles where high enough where a replacement would make sense. I did the update, paid 100€ for it and the battery life went from 4 hours to 8 hours...

I took the phone back to them and after another look they suggested me to do a fancy factory reset while connected to a mac and without restoring from a backup. Lo and behold the phone went back to normal battery use and is now usable again.

Anyways, I didn't want that stress in my life so I went with an iPhone 14 pro max and now battery is not an issue anymore.

Yes, usually after a couple of years. The battery health sometimes says the battery is ok, but I see a clear improvement from a new one.

Curious to hear about this too.

My phone battery has definitely degraded but I'm thinking just upgrading the battery might be a good way to do.

I'm on an iphone 11 BTW, which had pretty good battery/power specs at the time, so it's still ok now, but maybe with a new battery it could be awesome for battery life.
