My iPhone XS has a battery health of 75% and I can now barely leave the house with it without a plan to charge accordingly during the day.

It’s been charged wirelessly overnight since new, on a Nomad charger - I think it’s been quite detrimental to its longevity compared to previous phones I charged with a lightning cable.

#19. Don't charge your phone with a Qi or merely MagSafe-compatible charger. These chargers are inefficient and cause a tremendous amount of heat to be generated, which is bad for battery longevity and can potentially cause your iPhone to throttle its performance in addition to slowing (or even pausing) its charging. Use only bona fide MagSafe wireless chargers or wired charging. Apple has reportedly contributed to the development of the Qi2 standard. When Qi2 chargers become available, they will likely be good to use.

Charging to 100% is hard on Li-Ion batteries. The stress starts ramping up above the 80% mark. The closer you charge to 100%, the worse it is for longevity. Similarly, the further you let the battery discharge below 20%, the worse it is for longevity. I'm not a fan of letting a battery rule my life, but this is something to think about.

There are often periods of rapid battery drain following an update or release due to behind-the-scenes syncing
Apple cares about your privacy so much, they don't even keep records of previous indexing and has to reindex every iOS install, crazy.
 
Why on earth would anyone follow these steps? Literally go and buy a Nokia 3350 if all you want is a phone that has a long battery. You buy an iPhone for the mentioned features - this is just fear-mongering and people should just use their phones as intended, not purposely nerf them. Each to their own I guess 🤷‍♂️
I wouldn't do this stuff day to day, but it can be good to know how to lower battery use on certain occasions when you'll be away from power for a while. Myself, I just use Low Power Mode in those kinds of situations and leave it at that.
 
i think the real issue is that Apple has added enough new features to completely negate the battery life gains they made back when they released the 13 series. We need another major bump in battery capacity to keep up with new things like AOD, live widgets and live activities.

Hopefully apple takes advantage of the size increase next year to do exactly that.

Don't heat up your battery. Avoid wireless charging, don't keep fast-charging randomly throughout the day. Stick to wired 20W or less. Stick to overnight charging only, if your life permits. Don't keep your phone constantly topped off, it stresses the battery.

The backlash to this article is rediculous. There are plenty of use cases for further improving battery life. For me, low power mode gives an extra ~20% without changing the way I use my phone.

I don’t know about the iPhone 15, but I’m a new user of an iPhone SE 3, and man, this device keeps giving me lots of joy. With my iPhone 8 I had to charge it after half a day. With this SE 3, I consistently get 8 hours of screen-on time, plus some few more of screen-off time (podcasts, radio…). I’m really amazed.

Last night, I went to bed with less than a 50%, well today I had to do a trip, so I got into the car with just a 38%… then I enabled low power mode, because I was going to use the GPS navigator of Apple Maps. I knew, from experience with my iPhone 8, that turn to turn GPS navigation eats the battery at a fast pace. But then, I arrived to my destination (1 hour trip) with still 25%.

Now it’s almost midnight here, and I’m still using the remaining 10% to write my replies on MacRumors.

I’m absolutely amazed by this battery life on iOS 16.6.1, but at the same time, I know that whenever I update to iOS 17 I’m gonna notice a worse battery life, because as @Saturn1217 said, with the addition of new features, the SoC has more and more tasks to perform…
 
I don’t get people that are overly obsessed with preserving their battery health. Replacing a battery is very cheap, and even with heavy use you shouldn’t need to change it more than every two years or so…

If you are at the point of buying an iPhone 15 PM and disabling live activities, disabling always on display, removing widgets, etc, you are condemning yourself to a relatively poor user experience for very little gain IMO.

Also, it’s surprising that this article says nothing about charging method (wired vs MagSafe)

I'm not obsessed with preserving battery health, it just last for many years. Funny enough I don't use any of those features, except live voicemail. Quite happy with my phone experience though, and my ancient 7.5W Qi charger which is very gentle on the battery (it's all about total cycles and a little bit about how fast you charge, wired or not).

But let people do what they enjoy, it's their phone.
 
There's so many "tips" I don't understand. But there's another one :D Turn the damn Background App Refresh completely OFF! It doesn't affect messages you recieve! It only allow apps to follow and track your position etc.
 
I've been browsing for 4h today, 50% of the time playing in browser videos, played 3-4 matches wild rift all on wifi + vpn and drained around 30%. I really don't see any battery issues.

I know you were joking but I actually have a short cut for that.

Enter WiFi X: enable airplane mode (WiFi Calling still lets me receive texts and calls)
Leave WiFi X: disable Airplane mode
Just made this shortcut today and it works perfectly. I have very bad reception with a metal roof, so WiFi is a must. Thank you!

The discerning power user would never just shut off all features. “One at a time and test” is the order of business for anybody who values the money they’re going to spend on this device.

The article was just mentioning things you can do to use less battery. It didn’t say you had to do ALL of them!
Tip 20: Skip this year's models :D
You could also skip eating because the Ghost Pepper, if used carelessly, can put you in the hospital. Better not eat any peppers of any kind!
Turn off every feature, got it 👍
Again, where does the article say you have to turn off EVERY feature?

”I like pancakes!”

“Why do you hate waffles so much?”

”Wait…what?”
Why even have a phone, I guess.
“I like cake and ice cream.”

“What do you have against pies? And milkshakes? You should just skip all deserts for the rest of your life!”
right? it’s unfortunate how many things have to be turned off or adjusted to preserve battery.

I personally like getting the most out of my iPhones so I have a lot of the things in the article turned on.

I have AppleCare and chargers are always around so I’m not worried about loss of battery life or it aging quickly.
At least you have a strategy.


I swear, a lot of people just need to calm down and take a breath. I barely got through the first page of responses and all I read is people who DON’T HAVE the new iPhone are all telling the rest of us not to get one, or to just shut off all the features.

Seriously, it’s going to be the CALM and LEVELHEADED person who’s going to benefit the most from the iPhone 15. You may be a minority of customers, but YOU will be the most successful power users. You will be patient. You will, if needed, choose one or two features to disable just because they’ll be too annoying to leave active. Then you might choose one or two features you can do without, and that will bring your battery drain into something resembling a WORKABLE strategy.

The rest of us really should calm down. Or maybe we’re just not suitable to be users for the advanced hardware that Apple makes…advanced hardware that basically pampers the average user to the point of annoyance.

You know I’m right! 😉😄

I'm with you on that. Battery is totally fine for me too. Now whether I can keep it that way for a year is a different story.
