iPhone 15 Battery Capacities Revealed in Regulatory Database

[Mother Nature]

Every year the same "Oh the new chip will give massive battery life increases because of efficiency." It never does. Even when the M series were introduced in Laptops Apple had to put the largest battery allowed in a laptop you can travel with in order to get the type of battery life it gets.

These chips just don't ever give what people think they are going to give, at least not year over year. Every year we will just see small, incremental improvements.

For the performance per wat that they deliver, it's actually an improvement in a certain way.
You can do things faster and more efficiently while keeping great battery life. If you don't spend the same amount of time doing certain tasks, then your battery will last longer... again... in a certain way this is true.

iOS 17 will use more energy than iOS 16, especially with those interactive widgets that will draw more power; it won't be a lot, but enough to be perceived by the user when the battery discharges faster. So they play safe and don't announce any battery life improvement.

Apple battery tests are based on simple video and audio streaming playback, so no.

The problem apple will have at the moment is that the costs for supporting so many iterations and products balloons... keeping parts in stock, manufacturing more... making sure software

Let us take macOS on Macs.

Software Updates end after the 1st 8 years then Security Updates continue an additional near 2 years.

So the Mac is good to be used for approx 10 years. In terms of die shrinks that's jumping from a 22nm to 5nm device.

As it is right now Apple's iOS implementation is good. Not having the latest features that will slow down older hardware is good too.

If the user is unwilling or unable to replace approaching 8 years then are they really the market for the latest and greatest?

As I pointed out earlier devices in our pockets do not last that long and those with the means will replaced sooner than 8 years.

Would it be worth any company's time to support hardwared that originally numbered in the hundreds of millions when they dropped to mere hundreds 8 years later?

I've heard of someone proposing that there be a fee for extended support. Would people that cannot afford a new device be willing to pay for extended support or even understand what it means? Remember, they'd need to raise enough revenue to pay a software dev that costs them about $100k annually.

It is today's equivalent of Apple spending any money to support 32bit-only 2006 Intel Macs. It makes zero sense to do so.

I doubt my Intel Mac mini I bought in 2020 (2018 Mac mini) will get 8 years of software updates (counting from 2018)..

Id be very surprised. likely this years MacOS will be last or second last update before it only gets security updates.

Apple never disclose how long any device will be supported. They never make that commitment.. and length of support has varied considerably over the past 20 years. I think its been particularly short since the 2016 models

lucky, just checked and mine is at 87%, which feels overstated based on how quickly it drains. my favorite is leaving it off the charger over night at 60%+ and waking up to it being just over 20%.

The life remaining is just one parameter regarding battery health... the way its implemented I think it just measures the capacity.. and doesnt analyse the runtime given a particular load or usage. The internal resistance of the battery increases as it ages/cycles... therefore the energy you can get out is actually less than its capacity as some is lost as heat as the power is drawn.

I think this could be the main reason that your battery life doesn't seem to correlate with the decrease in battery health.

 

[HorstBockman]

I hope there were new batteries, not the same ones they used in 14 Pro, which lost 10% of its health after a year...

Do you charge to 100% on a daily basis, which stresses the battery? On average, I've done it every other day and my 14 Pro Max health is 98% after ~11 months.

 

[HouseLannister]

So moving to 3nm on the Pro line didn't give us ANY battery gains despite the battery getting physically bigger? At least it didn't go backwards, but I was hoping for something a bit more. I guess any optimization a smaller chip has is lost to the more powerful GPU, addition of WiFi 6E, and Thread radio(?)

The gain was a 10% uplift in clock speeds. It was just completely unrealistic to expect a big gain in performance along with power efficiency. You can't have both. GPU and 6E aren't used in battery tests.

 

[Marie.D]

At least it’s not a decrease. I’ll wait on real world tests to see if the 15 Pro can hold decently, hopefully it does decently and I can use that £200 savings towards AirPods Pro.

 

[dannys1]

It won't help me when 30% of my daily battery usage is 'No Mobile Coverage' because Apple refuses to have an option that when your phone is at home, connected to Wifi calling, it would stop looking for a phone signal.

 

[Shooter]

dannys1 ... i THINK you can achieve this by going airplane mode, then switching back on wifi ... used this method to switch between Vzn eSim and giffgaff Sim card while traveling UK to use verizon wifi calling back to US without being "seen" by local towers and charged long distance by Vzn

 

[xARx2]

Hehe, you have never had a dead phone.

no, I have

 

[svish]

Good to see an increase in battery capacity

 

[BigDO]

Thicker phone and yet a very marginally larger battery.

I wonder if the 15P will have battery life closer resembling the 14P rather than the 13P. I was hoping to some increase vs the 13P.

 

[MadDawg2020]

brand new chip, same screen, and only 74 mAh improvement? How??

Except it’s not the same screen because it is running brighter at more NITs , the new processor SIP runs faster with more cores, plus there are new features like wife6e and enhanced satellite and so on, so newer faster tech, brighter screen keeping the same better life through better efficiency, sounds pretty good.

 

[Clamjuice65]

And it will never go below 81% before your Apple Care+ expires, so you can’t replace it for free 🙄

Funny how that works huh 🤔

 

[FriendlyMackle]

I hope there were new batteries, not the same ones they used in 14 Pro, which lost 10% of its health after a year...

My one-year old 14 Pro Max is still at 100% battery health.

 

[FriendlyMackle]

Keeping your battery at 100% health is very easy if you know what to do.

Charge your iPhone to 80% maximum and then don't let it drop below 40-50%. You'll still be at 100% after a year.

This is pretty much what I do, though some days I do charge to 100%. And I pretty much only use my magsafe charger.

 

[Evelyn Harthbrooke]

Why can't Apple have larger batteries? Yesterday I watched a review of some phone I've never heard of and it had 15,000 mah battery.

Because not all phones need that huge of a battery? Not to mention that large of a battery will take hours to charge. And that phone isn't even high end.

Also, the batteries ARE larger, compared to last years' models. Apple does not like the idea of throwing in massive batteries for the sake of it, when iOS is crazy optimized as is.

My sister has a 13 ProMax. at 83 percent. no free replacement AC terrible.

 

[airtonvfilho]

i just hope that iphone 15 pro max has a battery at least the same as 13 pro max

because 14 pro max was such a disappointment, 13 pro max battery was way better than this

I honestly don't want to get into an argument, but everyone I know with an iPhone (granted, I don't know anyone with a pro model in real life, because over here you'd spend over $2000 for a pro model) has had issues with the battery life. I've had issues with iPhone 5s battery life since I have gotten it, the same with the people I know that have iPhone SE's and 13 mini. I myself have 12 mini and the battery runs out crazy fast, yet the battery health is 84%. My mom has Samsung Galaxy A51 and her battery lasts way longer than mine and she watches YouTube etc on her phone. My dad had iPhone 7 and now has the new iPhone SE and both of them have bad battery lives and his Samsung ( I don't know which model) lasts way longer. The batteries aren't that much larger and some phones with large batteries charge pretty fast. Especially Xiaomi phones.

I don't see iPhone being that much better optimised than mid-range Android phones. Android phones have always lasted longer when it comes to the battery life. The only reason why I picked iPhone was the updates + security updates and the speed. There might be exceptions as I don't know every Android phone, but from my experiences when it comes to Android phones they tend to be fast only in the beginning. My budget Motorola phone was fast in the beginning, but now it's crazy slow and not even factory resets help anymore. There are many benefits when it comes to owning an iPhone, but in my opinion and based on my experiences the battery life isn't one of those benefits. The battery lives on Android phones have always been better with the exception of Huawei Sonic, which I had back in 2011.

I do pretty much exactly the opposite and my launch day 14 Pro Max battery health is still 100%. My launch-day 13 Pro Max, 12 Pro Max and 11 Pro Max were all also still at 100% health when I traded them in.

I always charge to 100% (with optimised charging turned on) and my battery is usually around 10% when I next put it back on the charger. On quite a few occasions I let the battery drain all the way down to the point where the phone shuts down. Things that I think might contribute to my good experiences with battery health are that I typically go 3 or even 4 days between charges and when I do charge I do it overnight on a quite low power (7.5W I think) wireless charger.
