iPhone 13 Pro Max 13 pro max battery health drop

[1BadManVan]

I’m actually a bit surprised by this, I got my 13 pro max at the end of October and realized tonight that my battery health has already dropped to 99%. I’m fairly surprised by this because I only charge it at night, all my other phones I’ve had to top up here and there during the day and then charge at night.

The battery life is fantastic on this phone, so good that it never needs to be topped up. So how is that a phone I’m charging less often then any other iPhone I’ve owned, has already dropped in battery health when it’s less then 2 months old?

That is quite odd to be fair. I've had the 13PM since launch day and I'm on 100%. Though I will admit I have changed the way I charge my phone - I only charge it to around 80/85% because the battery is that good. I also don't put it on charge overnight - my last phone, XS was always on charge overnight and the battery health was like 83% by the time I got the 13PM.

I'll also top up my 13PM as needed to make sure it never drops below 20/25%. I'm very rarely away from a charger for more than 8 hours at a time and the 13PM easily lasts 24 hours for me from 85%

The more you keep it at 100% the more you’ll damage the battery. Charging at night is the problem. Little charges during the day and not going over 80% is best

 

[now i see it]

The battery Health indicator is only an estimate and it’s not accurate. I’d give it a +- accuracy rating of maybe +-4%.
The moment the battery leaves the battery factory it starts degrading whether it’s being used or not. Using it hard (full charges and discharges) degrades it faster but it ages regardless. Technically, the battery no longer can be at 100% Health soon after leaving the battery factory.

The 100% Health rating in the iPhone app is just a ballpark figure based on assumptions.
The iPhone battery really only has 5 Health levels to pay attention to before it’s virtually worthless:
95%, 90%, 85%, 80%, 75%= dead battery.

Use the phone as intended.

This is BS, no offense

I tried that for an entire generation (charging only up to 80%, keeping it between 65-85%, optimized charging enabled for overnight charging) because I wanted to preserve my battery health to sell it later on. I actually ended up with a lower % than if I just had charged it when I needed to and all the way to 100%

I think 'helping' the battery by scheduled charging is giving diminishing returns.

Ironically, when I acknowledge that I will eventually replace the battery at Apple, my phone's battery health drops much slower lol

Well, that is the accepted science behind it, more than that I don't know XD probably heat is the major battery killer. If you use it for gaming or 4k video shooting it will degrade faster for sure

I’m just surprised it dropped so quick, like I said, ive always charged my phones overnight. I always do my best to keep the battery above 40% which is easy to do with this phone. And yet it dropped down faster then any other iPhone I’ve had.

Hopefully means nothing in the future

watch this and it will hopefully cure some of that battery health "anxiety" because trust me I've been there before!

Great video. I’m guilty of the 80/20 charging and don’t currently charge overnight. I am thinking of saying screw it and just charging overnight with a slower charger. I have apple care, so I might as well get some use out of it when I eventually need to replace the battery anyway. I’ll admit I have charging anxiety for sure, and it’s gonna take me a bit to “get over it”

Don’t give up so easily. Get a HomeKit compatible smart plug and set up an automation in the Shortcuts app to turn off the charger at any set level you want (and turn it on at any level too).

Funny you suggest that, as it’s precisely the method I use right now haha. I may just try not to be so obsessive about it.

I’ve gotten phones from the factory that have had 96% capacity. Batteries are not all identical. My 12 Pro Max was 104% capacity. My 13PM is 102.9% capacity. They all drop differently too.

My wife and I buy the same phone. And despite me babying my battery and she heavily using her phone we usually trade in at similar capacities.

Unless you plan on keeping the phone for five years I’d not worry about it. Using an app like coconut battery gives you a much clearer picture of your phone over its life.

Yes heat is the worst for a battery.

There are bound to be some batteries with bad cells that make it off the line. Not saying that is the case now, 1% down is hardly a major concern, but if it becomes a problem hopefully it manifests itself inside the warranty period. Fortunately, even if it doesn't and you're out of warranty, the cost to replace the battery is $69. Pretty minor expense for a phone this expensive.

anyone else experiencing unusually warm phones while charging? I just got a 13 pro last week and every time I plug it in it gets warmer than I am comfortable with... and warmer than any other phone I've had. if it isn't normal I will bring it in

20 watt charger pushes more power through the battery which creates heat. The charging circuit inside the phone monitors temperature. It’ll cut back the current if the temperature gets higher than the designed specification.
Battery charging is a trade off between speed and degradation caused by heat. Apparently the designers think the heat created from faster charging is acceptable.

Of course they think the heat from faster charging is acceptable. They are not the ones to deal with a worn out battery after a year or two.

Manufacturers want you to buy the new phone every year. The industry is absolutely loving fast charging while battery tech remains the same.
