iPhone Battery Health: 16 Pro Max

You may not like to hear that it is completely normal and your battery is performing exactly as it should be performing. On average, for every 50 cycle charges, battery health will decline about 1%. So, 276/50 = 5.52. You should send flowers to Apple as after 276 cycle charges, your battery should be in in the 94% - 95% range. But you're at 98%, so kudos to you!

Keep in mind that battery health decline is not exact, nor linear. It can remain stead for a while, then drop a few points all at once. Don't be surprised to see your health drop a few more points.

There is not one thing wrong with your phone. It is performing better than spec. And battery health decline cannot be stopped, no matter what you do. The battery limit is honestly more gimmick that not. It won't stop battery health decline. In fact, in a scientific study, performed by an independent engineer, they used two iPhone 16 Pro Max phones, both used exactly the same for an entire year. One phone had Optimized Battery Charging, where the phone charged to 100%. The other had the charge limit at 80%. At the end of the full year, both phones had the exact same battery health.

Apple is not trying to make you buy a new phone, unless you expect to own a phone with 100% battery health. I guess you could keep buying new phones if that's what you want. But the reality is the day will come when the health of your battery dips to 80% and that is when it's to pay Apple to replace the battery in your phone and it will then go back to 100%.

Or you could switch to an Android phone, which doesn't have any way for you to check the health of the battery. Yes, it will decline as all batteries decline. But at least you'll have no way of knowing the battery health is declining. What's the old saying? Oh yes, I remember........."ignorance is bliss!" In other words, you can't worry about what you don't know.

I have the new iPhone 17 Pro Max. My battery can go well past a day's use and then some. I had the 16 Pro Max and it too went all day without needing to charge it during the day. The absolute best practice you can do for your battery is to charge it at night when you sleep, leaving it plugged in to Charge ALL night EVERY night. Personally, I'd turn off the Charge Limit and instead use Optimized Battery Charging. You'll wake up every morning to a fully charged battery, which should last all day without need to charge it until you go to bed at night.

Keep in mind no two people will get the same battery life, even using the same model phone. There are too many variables. Do you stream videos or music a lot? That will eat through a battery. Do you game much? That will eat through a battery. Are you close to a cell tower or does your phone have to work harder to stay connected to cellular data? That can eat through a battery.

Given that your phone is actually doing better than average, I'd just enjoy the phone and stop worrying about something which is normal, expected and can't be stopped.

Take care........

All day battery life is the expectation where you should be charging the phone all night, every night, and I recommend Optimized Charging instead of a Charge Limit. If you are looking for the unusual case where that is not possible, then you need to purchase a battery pack.

I do remember the old days when the flip phone could last for several days, but I also remember that texting was done by 33,444,22,666, and the game I played was the snake game on a low quality LCD screen that was capable of viewing about 8 lines of text in black/white. I don't see us going backwards in that regards and our devices are much more powerful now, which also means they require more power.

Your battery health is beyond great with 276 charge cycles and actually that is not normal, or I should say expected as there is no such thing as normal, and it should be showing less. Quite the opposite of what you may be expecting. Also note that Battery Settings are only updated when the phone is able to charge to 100% for optimization. It will still do that on occasion automatically if it is not removed from the charger prematurely. That is one reason why you may see a larger than expected drop, and none of the drops are linear.

Spend more time enjoying your phone and less time worrying about your battery. It is designed to last 1000 charge cycles, then will be time for a new one when the Battery Health drops below 80%.

You will get better performance and at least equal long term results if you ignore the Charge Limits and set up the iPhone for Optimized Battery Charging and let the phone charge all night.....every night.

It's funny that no one seems to complain that only charging the battery to 80% means that the phone won't go as long before it needs recharging and there is more wear and tear on the battery charging it more often.

Probably another discussion, but Charge Limits is more of a gimmick than anything else. For starters, the battery is still going to charge to 100% a few times a month no matter whether Charge Limits are set to 80%, 90% etc.
