i Have a Iphone SE 2nd gen i had it since April of 2020 and its at %89 Maximum Capacity. When should i change its battery with a new one?

I have a IPhone 12 Pro Max and my battery health is 86%. What percentage should it be before I replace the battery in it?

So after nearly nine months of owning my XR, my battery health hit 93 percent the other day. I love this phone, but I'm not too sure what I'm doing wrong in terms of charging.

I average anywhere from 5-8 hours of SOT on iOS 14.2, which probably would be a lot higher if I had used better charging habits to preserve the battery health. It also depends on what I'm doing on my phone, of course.

I used to be getting 9-10 hours of SOT, but... the battery health was higher back then and that was on iOS 13.

Anyway, when is it time to replace the battery? How does battery health affect usage habits? I don't think 93 percent is too bad after nearly nine months of having the phone, but I do wish I charged it differently...

Edit: Thanks for the reassurance everyone!

I ust got a referbished 14 plus from bestbuy solely for the use of my insulin pump and sensor so its only connected to wifi at home and low frequency bluetooth , all other features and apps are turned off or won't be used, I dont have my new pump yet but the apps for the pump and sensor run 24/7 , my battery health is at 79% should I try to get a different one or should this one be able to last 16hrs between charges given the limited use?

Hi. Got a battery replacement about a year ago on my kid’s iPhone 7, done by 3rd party repair centre, not Apple. So it’s probably not a genuine battery. Anyway, it’s barely holding a charge and dropping rapidly from about 30% to dead in a matter of minutes. In the Settings, the battery health (capacity) is showing 100%

Is there a way for repair centres to manipulate this so that it shows 100% when it’s clearly not?

Tried full restore a couple of times to see if a rogue app is causing the rapid drain, but even starring as a fresh install of iOS, the drain is there.

I got IP 11 on November 2020. Now, the battery health is at 75%, so i was wondering when should i get it replaced?

Also, I've heard that the phone has unexpected shutdowns when it's at low BH, so i would like to avoid that and replace the battery before that happens.

I just checked how many battery cycles my iPhone 11 Pro has gone through: 873. This phone was made 08/26/2019, so it's roughly 3.5 years old. Now, I think, is the best time to replace the battery. Why? Because iPhones are supported for 7 years (right?). I would expect the last iOS for iPhone 11 to be released in 2025, so with the release of the iOS in fall of 2026, the iPhone 11 Pro will be obsolete. This means I have 3.5 years left of updates of my iPhone, so I should replace the battery now rather than wait a year to change the battery.

Is my thinking about this correct? I know some power users may go through cycles more quickly. But I think 1 or at most 2 battery replacements to be optimal if one plans to use an iPhone the entire support cycle.

I have an iPhone 12 and it’s exactly 1 and a half year now. And my battery health is at 83% having an average of 7hrs screen on time based on the information displayed in Battery in the Setting menu.

I’m just curious if how long it take before you guys change your batteries ( I assume once it goes lower than 80%??) or do you guys have to repair it due to other reasons?

Does my battery health normal or it’s faster than normal? I used data all day due to work and used wifi at home at night and on weekends.

My first time iPhone and used to be an android fan and I never change my batteries then.

Hi! I know the title sounds a bit clickbaitey, but I truly do mean it.

I got my iPhone X 64gb secondhand from my mom when she upgraded to an 11 Pro Max, and she wore the battery in this thing out. It was at 86% health when I got it in December 2019 (bought September 2018 iirc), and by now, August 2020, it was down to 81%. Well, I got sick of my phone dying during the school day, so I saved up the $73~ to get the battery replaced, and boy was it a process.

I went to Best Buy on August 29th after finally getting an appointment, and while I know it's irresponsible to unnecessarily go places like that, waiting 2-3 weeks to mail my phone in didn't sound appealing (and I was paying in cash) at all.

The first thing they did was run a diagnostic on the battery. The Geek Squad dude told me that the test basically checks the battery's cache to look for irregular/short charge cycles, and to test other info. They do this test if your phone's battery health isn't under 80%, as Apple won't allow them to replace a battery if it isn't under 80% or if it passes their testing. Except, mine wouldn't do any of the above. It tested, tested, and tested for half an hour. It got to the point where the technician said that it was going to fail at this point, and they got the manager to override and approve the repair.

Well, what I expected to be a 5 minute drop off (my fault for having optimistic expectations I guess) had become 45 minutes. Eventually they returned and gave me the papers necessary to approve the repair, and after disabling FMI and removing my passcode, they took the phone and went to work. 15 minutes later and I was done.

I left the store at around 4:35pm, and by 5:30pm my phone was ready to pick up. I got there, checked in again, and went to Geek Squad, and waited for the technician to bring my phone out. It took him a bit to print out my receipt and to give me the paper authorizing my pickup, but it was chill. After an awkward conversation with my retired highschool counselor, I finally got my phone back.

This all happened yesterday, and I can't believe how long my phone lasts now.

This link has a screenshot of my runtimes (the first thing you see when you open the battery tab in settings) and I'm stunned.

I unplugged my phone at 6:45am (screenshot says 12:30pm because I plugged it into my MacBook to check Coconut Battery out of curiosity, but it hardly affected the charge level.) and only at 8:46pm, at 15%, did I have to plug my phone in.

I mostly use my iPhone for iMessage and social media, and even TikTok which kills the battery (probably because it's busy doing whatever background stuff) only brought down around 5% an hour. I can't believe my phone actually lasts this long. My replacement SE (first one's battery swelled within a year of owning so they replaced it) made it to around 5:30pm before needing charged, and while I still love that phone (and so does my sister who got it) it can't even compare. My other sister's iPhone 11 probably crushes mine in battery too, which is nuts.

-TL;DR

If your iPhone is dying quickly like mine was, please just save up the money to get it replaced. You won't regret it.

Hey everyone, I have an iPhone 14 with 84% battery health, and lately the battery life has been terrible — it barely lasts half a day with light to moderate use.

I’m considering getting the battery replaced, but I’m not sure if it’s worth it yet or if I should wait until it drops further.

Has anyone replaced their battery around this level of health? Did it make a noticeable difference? Any advice would be appreciated!

Thank you!

Hey guys, I currently have a XS and am weighing upgrading to a newer model vs just changing the battery. I’ve heard Apple slows down your phone as the battery ages so to people who changed their battery on an old phone, did you notice any performance improvements? I notice my phone freezes or loads apps slowly now, but not sure if that’s due to the battery or apps just becoming more complex.

Hey everyone, I have an iPhone 13 Pro with 77% battery health, and I’ve definitely noticed it draining faster and heating up more during regular use. I’m trying to get the most out of this phone before upgrading, so I’m debating whether to replace the battery now or wait until it drops further.

A few things I’m wondering: Is 77% battery health low enough to justify replacement now? Will waiting until it hits 70% or lower cause any long-term issues or performance throttling? Has anyone here replaced their iPhone 13 Pro battery through Apple, Cashify, or any trusted third-party? How was your experience?
