iPhone 14 Pro Max Battery, do and don’t do

Use the genuine chargers, or chargers from a reputable company and don't use fast charging unless you really need to, as this creates heat and heat is what kills battery life.

I've used the old 5w chargers overnight for years, never had a single problem. My 13 Pro from last year is still on 100% battery health, and I continue to charge my 14 Pro this way as well. There's enough things to worry about in life than to add looking after a phone battery lol.

Just charge it when you need to, and don't let it drop low if you can help it.

I also use the 5w chargers overnight. Years ago I think many of us always charged to 100% as a remnant of those “memory” issues that other types of batteries would have. When charging my iPad I aim for around 80% but often forget and it goes to 100%. Probably doesn’t matter a lot. But like @RRC said, it’s the heat that’s bad.

Thanks! Yes I always use the old white 5W chargers too. So don’t let it drop let’s say below 20% and don’t charge it to 100%.
Given how I use the PM14 means I will trickle charge it every 2-3 days. The battery of this thing is phenomenal.

Just plug it in and don't worry about it. You can get totally wrapped around the axle on all this battery stuff. Even with the older batteries that's all I've ever done with my smartphones since 2009.

My phones get plugged in at night and used as a bedside clock. Taken off the charger when I get up. End of story.

I let Apple's optimized charging and charging circuitry worry about it all.

For the record, my 6s+ battery didn't hit less than 80 percent health until November 2021. That's six years, including three summers riding around in Phoenix, Arizona summer heat in a car with no A/C.

Exactly. Enjoy the phone.

Is 20W considered "fast charging" that will "kill" my battery?
I charge my 13 PRO from an average of 40-50% to 95-98% every morning, sometimes 100%.
I'm using a 20W plug-in Apple charger and Apple Lightning cable.
During & after charging, this phone never feels noticeably warm at all.
At one year old, my battery condition is at 100%.

use a Gan Charger it will further protect your battery I’m hearing
 
A battery replacement is less than $100 and you will be expected to replace your battery every 2-3 years if you plan on keeping your phone.

It’s not exactly a big expense so just charge to 100% and enjoy using your phone. There is no need to be OCD about the battery or to allow battery health to control your behaviour.

It has more to do with what the best way to do something is, rather than a behavior control issue.

No matter what you do, some batteries just are worse than others.
My iPhone 11 only dropped from 100 to 99% over a year.
My iPhone 12 Mini dropped from 100 to 79% over a year and three months, and I just got its battery replaced. It was also frequently overheating, and would completely refuse to charge over MagSafe a lot of the time.
I think all the other posters are right, just use the phone and don’t worry about it.
You can absolutely baby the battery, and have its health degrade extremely quickly.
You can treat the battery without a thought and only have it drop to below 80% after six years like one of the people above.
While there are obviously do’s and don’ts, the truth is there’s no absolutely perfect solution.
If you have Apple Care or insurance through your phone carrier, most will cover a battery that’s below 80%, usually no questions asked

If we had user replaceable batteries like the old days - nobody would care or obsess over any of this…

Like what old days? iPhones have never had 'user-replaceable' batteries to the extent of removing a back cover and hot-swapping. They're the closest to user-replaceable they've ever been currently, with the self service repair program.

Some people talk about charging between 40-80% among other permutations, not charging overnight, etc… that is an issue, tbh. I want my phone to have a full charge when I need it. I take care of my phone but it is still a tool to be used and I will not baby it. Batteries can be replaced so I will not change my routine to obtain an extra 6 months of use out of it.

Practical advice such as using a 5w charger and avoiding fast chargers are fine though as it is not noticeable if you are charging overnight.

I use fast chargers on occasion, a MagSafe battery, wireless chargers, charge from 1%-100% and charge overnight because I know I will be replacing my battery if I decide to keep using my phone.

WHAT is a "fast" charger? 20W? 30W? Anything but a 5W? 🤔
 
My iPhone 12's battery health is still at 90% after about a year and a half (410 cycles) of using 20W and 30W chargers. I haven't really done anything special with it. Sometimes I charge overnight, other times I'm just charging any chance I can get throughout the day, but so far it's been aging fairly normally.

I don’t know. To me it’s 20W+. I had an old 15W wireless charger for my iPhone 8 but never considered it a fast charger. I use a 25W fast charger for my iPad Mini 5 and 12 Mini.
