I’ve had an iPhone 12 mini since launch and the battery life has become pretty abysmal. However, I’m reluctant to replace it with a newer, bigger model. My battery health is sitting at 86%, which really doesn’t sound that bad, but I feel like the actual battery life is way worse than when I bought it. Has anyone replaced their battery around this percentage, and did it give a noticeable boost?

If your battery health is below 80% and you plan on not buying a new phone within the next year then you absolutely need and should get a battery replacement. Both for function, and safety. Don’t want an expanding battery in your pocket!

78% is basically dead. I’d replace that.

I’ll probably get something in the iPhone 16 lineup next year, since I do understand I’ll eventually have to give up on the small form factor. Battery health shows 86%. Also downloaded CoconutBattery on Mac and it says the phone is at 88.5% design capacity. I’m torn between spending $89 on the replacement or just sticking it out for another ~14 months, maybe using a portion of that money on a portable battery pack which could be used with another device once I retire the 12 mini.

72%, the only thing keeping this 7 Plus’ battery alive is powercuff.

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

Oh man, my 7 was a TANK. No case, battery lasted forever (or I didn’t notice it), just had a scratch on the screen.

My lighting port wore out which apple will not repair. Took it to a 3rd party place to repair and they messed up the antennas in the phone breaking NFC and wrecking the reception on it. Went direct to an iPhone 14. I have had iPhones since the 3G was released the years between replacement has been getting longer as time passes.

Thanks. I am satisfied with the performance as I don’t do intensive gaming or anything like that. That being said, I’ll probably want to upgrade to the iPhone 16 lineup as the screen/camera/etc. upgrades should be substantial by that point, and I know I can’t cling to the small form factor forever. That’ll put the mini at 4 years which I feel is respectable.

The SE models are still in that size, will be interesting to see if they stay that way when they go to the next Gen.

When I upgraded from the 7 to the 14 I didn’t even notice till I got it that the “normal” 14 was so much larger LOL.

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.
