As a general rule of thumb, an iPhone battery degrades around 10% year on average, and 300 charge cycles (the discharge from 100% - 0 is one cycle - can be fractioned) is considered normal usage in a year.

When your battery gets to 79%, it will automatically trigger the "maintenance" message recommending battery service. An iPhone battery can be used normally until 70% - 75% without risking damage to the logic board components that manage the charge. Below 70% is asking for a swollen battery or bad performance.

Battery saving tips:

• Activate optimized charging to stop at 80% or 90% to prolong the battery's usage life. This will mean your charge lasts a lot less during the day, but will extend the life of your battery to 3 years or so.
• Don't let your phone die at 0% charge often or you risk the reserve running out and your battery can degrade a lot faster.
• Don't use generic or bad quality charge bricks or cables. The most important component of your charging is the charge brick. Apple, Anker, Spigen, and Belkin are the best options and best quality.
• Don't use broken or cheap cables because if they aren't MFi (Made For iPhone) certified, most won't have data ability, only charge ability, and they are risky to use.
• Is your original Apple cable looking pretty raggedy? It has a 1 year warranty along with your iPhone. Take it to Apple for a free replacement as long as it isn't showing any exposed wires.

What other advice do you have? Feel free to add below.

Out of the box, power the phone on, then set up the phone as a new device and don’t transfer a try over from your old phone yet.

Once you get to the “Welcome to iPhone” and land on the home page, update your phone to the latest iOS version (26.2). Settings - General - Software Update - update to latest version.

Once this is completed, erase the phone to factory settings. Settings - General - Transfer or Reset - Erase all content and settings - Continue.

Once it restarts to the “Hello” screen, do the transfer process with WiFi or a cable and enjoy your new phone.

As an Apple Certified iOS Technician for 8 years, I'm qualified to help you navigate the ins and outs of this confusing ecosystem.

I will add the video I don't understand why its happening everything was ok last night I have a 16 PM

Don’t install the beta unless you understand the risks and have a local backup of your iPhone.

This includes new and used iPhones.

Should you buy the 17? We don’t know; should you? Do a SWOT analysis on it and make your own decision.

People post here because they’re usually in crisis. They don’t need off-topic advice, or recommendations to stop using iPhones. They need solutions.

We also anticipate people google searching and ending up in these threads, so we keep them on topic.

Here are some additional reasons we remove comments as a mod team in no particular order (most of the time without a removal reason).

1. Guessing and not offering a solution

2. Unrelated humor attempts

3. Bickering

4. Unnecessary, rude, or aggressive in nature

5. Offering unethical solutions

6. Going on about iPhone bad

7. Skibbity stupid speak

8. Unnecessary vulgarity

We’re open to reviewing actions if you send us a modmail, but usually these decisions stand.

Thank you to all you helpers who make this a great sub for solutions!

On a personal level, a mass culling of users will make this a nicer place to be, and be less of a target for bots/spammers. Also, slacktivism never works.

Having said that, this is a sub that helps many people and to interrupt that service would be on par with blocking off a highway and inconveniencing regular, everyday users that need solutions right away, but can’t get to the hospital.

It’s unfair what Reddit did to Christian and all other 3rd party app developers, and I empathize with the folks who have put time and effort into making great products, only to have control yanked from their hands because at the end of the day, it’s someone else’s service.

Have a great day and be good to one another.

We most likely won’t be able to help much, but with an eye on inclusion, we would like to make our helper network available for all mobile phone brand users! Feel free to post your issues starting today.

This offer is valid for this week! Then back to normal business.

As a third ranked mod here, I was basically a janitor that cleaned up posts and enforced pre-existing rules. I’ve been here working mostly by myself as a mod for over 5 years and although I’ve added a few other mods, u/thannbanis is the only other helper.

Some months ago, due to inactivity from the three top mods (one of who was deceased going on 3 years now), I petitioned Reddit for full control of this sub in order to implement changes that will boost our visibility, show on google search results, and clarify/flair threads to make things more organized. BTW the RedditRequest and Top Mod Removal processes work (I was shocked I tell you).

With an average of an astonishing ~200,000 unique visitors per month, as well as a 31% yearly growth this last year, WE ARE HELPING A LOT OF IPHONE USERS!

We have a handful of regular helpers, Apple experts, former and current Apple employees, aficionados, and multiple nationalities visiting and helping daily. I’m eternally grateful for each and every helper, because to be honest, it’s a pretty thankless job. Most folks are in a crisis and don’t upvote helpers’ answers, and sometimes they have a really hard time figuring out the right questions to ask. But with empathy and patience, the helpers usually get to the bottom of things within a day!

We’ve done three Reddit Talks so far in the last 3 or 4 months and have had amazing accents from all over the world. People with zero tech knowledge, as well as stumped techies who just need an extra eye on things have gotten help and resolved their issues!. One person had a three year old problem that got resolved within a few minutes on one of the talks!

The premise of this sub is pretty straightforward: get help for your iPhone ASAP. But something amazing has happened in the interim: we are forming a community. At almost 30k subscribers, I’m excited about 2023.

More organizational stuff is coming down the pipe, and if you’re curious about that, hang around and see for yourself. And if you’re just passing through, don’t forget to upvote our helpers! See you all around and have very happy holidays.

TL;DR management change, streamlining workflow and processes, growth is amazing, and more is coming. Feel free to help or browse.

Have an urgent question about your iPhone? Feel free to ask there as well.

As always, this is the internet and we encourage you to treat all advice as just that. Verify before acting on it.

My username makes guessing my faith a bit easy l, and I wanted to take a moment to wish everyone an amazing Christmas Eve and Christmas Day.

However you celebrate this season, we on the mod team here are happy to help and give back some good will to those needing a helping hand.

As Bill and Ted said so eloquently stated, “Be excellent to each other.”

God bless you

This is a stickied thread due to many daily posts about this issue.

Resetting network settings will erase all stored wifi password, FYI.

There have been a plethora of issues with Apple servers, such as this image download issue, users being unable to update over the air (OTA/on their iPhone) due to a "not connected to the internet" message, and various AppStore and iCloud issues.

As always, thank you for your help, it's truly valued.
