I'm curious to see how the iPhone 16 battery compares to the iPhone 15 battery.
AI will certainly consume more battery.
 
I know iPhones outside of the US have a physical SIM slot... Maybe this is the year that goes away on all phones, perhaps allowing for a slightly larger battery design?

I don't understand why Apple decided to decrease the iPhone 16 Plus battery capacity yet increased the iPhone 16 Pro Max compared to the iPhone 15 counterparts...
Assuming the rumors are correct, this is particularly puzzling - and aggravating. It’s almost like Apple is doing it to annoy Plus fans unnecessarily.
 
Would be quite significant since regular Pro is known to have mediocre battery life.
Known by who? Lasts me all day and I now only charge to 80% because it lasts so long. I use it constantly at work and start my day at 5 and put it down at 11. Recharge during the day maybe once a month. The battery life in the last 3-5 years has gotten amazing. I dont play games or watch videos much so maybe if you do those things its a problem but text all day and email and safari and other work apps nonstop.

For a list of a few historical comparisons (for the very few who don’t already keep their own list 🤓):
- iPhone 3GS (1200) to iPhone 4 (1420) was an ~18.3% increase.
- iPhone 5s (1560) to iPhone 6 (1810) was a ~16% increase.
- iPhone 6 to iPhone 6s Plus (2750) (does that count?) was a ~51.9% increase.
- iPhone 6s (1750) to iPhone 7 (1960) was a 12% to increase.
- iPhone 7 to iPhone X (2716) was a ~37.5% increase.
- iPhone XS (2658) to iPhone 11 (3110) was a ~17%.

Apple still cutting corners wherever they can. Their stingy RAM is why we’re only seeing AI in the top phones and now your £1300 iPhone still packs less battery than a £200 Android Phone.

I know the ADF will be out in force with the usual ‘it’s the software though’ excuses but it’s ok to demand better value from Apple!

Nothing really hit the ball into everyone else’s court this year with the CMF Phone. No it doesn’t have IP or NFC but the camera is actually really good and it has a 5000mah battery with a 120hz display. Its ludicrous value for £200 and crucially it looks interesting as well.

I’m not sure what their margins are but it should make every customer, Apple or otherwise demand more at their price point.

If Apple can’t find the room in their massive pockets for a 6000mah battery on their top phones and at least a 120hz display on the base models then something is terribly wrong.

A 6000mah battery with Apple’s software optimisations would give you 3+ days of battery easy and who doesn’t want that?!?
Apple doesn’t innovate anymore.
They see competition as an annoyance.
Like a fly buzzing around you but it’s wearing air Jordan’s and has a solid gold chain around its neck with a back to the future hover board.

All the while we’re all setting here with a black turtle neck on, worn out jeans and a pair of loafers passed down from our dads.

It’s simple.

Turn the AI off. It’s not going to be anywhere as useful as anyone thinks.

It’s going to automate tasks via verbal command.

Of which Siri already does.
And your finger tips are already capable of.

It’s going to be the “ New thing “ Apple justifies selling us another iPhone 12SSSSS.
 


The iPhone 16 Pro and iPhone 16 Pro Max are rumored to feature bigger battery capacities compared to previous-generation models, but it looks like the smaller iPhone 16 Pro device could see the biggest improvement, according to new details.

iPhone-16-Pro-Front-Update-Blue.jpg

Chinese Weibo-based leaker Instant Digital today posted the mAh (milliampere-hours) figures for the iPhone 16 Pro (3,577 mAh) and iPhone 16 Pro Max (4,676 mAh), with only the larger model capacity lining up with previous leaked figures.

The mAh is a measure of battery capacity, or the amount of electric charge that a battery can store. The higher the mAh rating of a battery, the more charge it can hold, and the longer it can power a device. The following table shows the battery capacity comparison between the iPhone 15 Pro models and iPhone 16 Pro models.

iPhone 15 Pros (2023)iPhone 16 Pros (2024)% Change
Pro3,274 mAh3,577 mAh+9.25%
Max4,422 mAh4,676 mAh+5.74%
The change in capacity of the iPhone 16 Pro over the previous Pro model shows the most marked difference, with an over 9% increase (303 mAh). Meanwhile, the iPhone 16 Pro Max, while not as dramatic as its smaller sibling, gets an over 5% increase (254 mAh). Combined with efficiency improvements, the increases should see both devices offer more sustained real-world usage on a single charge.

According to one rumor, this year's ‌iPhone 16 Pro‌ Max will boast a 30-hour-plus battery life (compared to 29 hours for the iPhone 15 Pro Max). Not only that, the iPhone 16 Pro and iPhone 16 Pro Max are expected to use stacked battery technology for increased energy density and prolonged lifespan.
Both devices are also rumored to support 40W wired fast charging and 20W MagSafe charging. For comparison, iPhone 15 and iPhone 15 Pro models are capable of up to 27W peak charging speeds with an appropriate USB-C power adapter, while official MagSafe chargers from Apple and authorized third parties can wirelessly charge the iPhone 15 models at up to 15W.

My iPhone 15 pro has the worst battery life of any iPhone I had since iPhone 12 it’s a catastrophy.

Some of your comparisons are invalid...

iPhone 6s had a lower battery capacity compared to iPhone 6 due to 3D Touch...

iPhone 8 had a lower battery capacity compared to iPhone 7 but seemed to have been offset by the newer chipset...

iPhone XS had a lower battery capacity compared to iPhone X but seemed to have been offset by the newer chipset...

iPhone 11 Pro had a bigger battery compared to iPhone XS due to the removal of 3D Touch...
 
Will be interesting to see how having the AI features running in the background affect battery life.
Running AI on Dev Beta 18.1 on my 15 Pro Max and don't notice any appreciable difference so far. But there may not be much happing in the background with AI yet.
 
About time. Regular Pro battery life is bad. It used to be better in previous models. And it usually gets the worst bumps, so well deserved.

Pro 15 battery life is fine for most people. If the battery life is bad for you, it's probably because of doing very heavy tasks for a long time, like playing games or having the screen brightness very high.


But won't this add more weight to the PRO iphones. They are already too heavy as is and is one of the reasons why I am considering going back to the non-PRO iPhone.

The 15 Pro is significantly lighter than the previous versions because of the change to titanium, so the weight issue was mostly solved there. If you don't have a 15 Pro then you can't really compare how big a difference it already is.

Also, it's not like the current phones are full of empty space. Any increase in battery size means they were able to make other parts smaller to free up space for it.


Is there a way to estimate how much additional battery time the increase will result in?

Apple generally targets a specific runtime and chooses a battery size to try to meet that target. An increased battery size more likely indicates high power usage by the internal components, and probably won't end up giving you longer runtime. This is most obvious with the Watch, but they do the same with all the products.
 
If Apple can’t find the room in their massive pockets for a 6000mah battery on their top phones and at least a 120hz display on the base models then something is terribly wrong.

A 6000mah battery with Apple’s software optimisations would give you 3+ days of battery easy and who doesn’t want that?!?

There are lots of people complaining about the weight and thickness in recent years, so it's not as much a universal want as it was back in the 6/6s days when Apple sacrificed excessive amounts of capacity for thiness. That said, I'm also in the camp of having as big of a battery as possible. The problem is that the competition isn't offering significantly better battery life despite having significantly larger batteries. Without meaningful competition, Apple becomes comfortable with the battery life it ships right now. For example, the S24 Ultra has 5000mAh, One Plus 12 has 5400 mAh, and 15PM has 4400 mAh, but they end up with near identical battery life with the iPhone even edging the competition in some cases. What we need is other OEMs working on their optimization and actually offering better battery life.

I’ll be going from 15 Pro to 16 Pro Max, that’ll be 43% jump in mAh which excites me!
 
Battery size increase is nice, but it should be overall larger when you consider that the standard Galaxy S24 6.2” has a 4000 mah battery.

This underplays the impact of AI running in the background. Wonder how Apple will manage their power use for things like filtering notifications.
I’ve been using the AI beta all week, so far there isn’t really a noticeable difference in battery life.
