Out of curiosity, has anyone been able to detect a significant change in battery life on the 12 Mini (or other new iPhone) by turning off the bluetooth radio completely from the Settings menu (not Control Center)? I have an iPhone SE2 with an even smaller battery, and simply turning off bluetooth saves about 40% battery per day. The bluetooth battery drain behavior started when I installed iOS14.
Given that 5G isn’t much faster than LTE, if at all, in many places, turning off 5G may have a bigger impact on battery life.

I’d worry more about 20:00 - 04:00 as it’s harder to be around a charger when you’re out for a night on the town.
You’re doing something wrong if you’re constantly using your phone
I didn't expect bluetooth to make that big of a difference either. But I see this behavior on my iPhone SE2 and iPad Mini 5. I've seen similar results on an iPhone X. I have a suspicion that iOS14 is doing something new in the background that's a major battery drain. I'm curious if others see this too, particularly someone with the latest chipset.
Maybe something related to the Covid tracking?
 
I HATE TINY SCREENS THAT ARE AS SMALL AS ANCIENT IPHONES. APPLE SHOULD JUST KEEP INCREASING SCREEN SIZES, NOT GOING THE OTHER WAY ROUND

I realise this is completely petty, but really the only thing giving me pause for the mini is the awful colour options this year. Black or white is a bit boring but the red is off from usual, the blue is .. well it's too blue, and I just don't get the green colour. We'll see if I cave and return to iOS in the new year.

Small phones dont have to have poor battery life. Sony nailed battery life on their compact phones years ago. My old z3 compact had one of the best battery lives on the market, even more than its big brother.

I think their trick was to simply let the smaller screen have a lower resolution. It still looked fantastic due to the smaller size, but was also far more efficient.
 
The real question is how the battery life compares to the previous small phones like the original SE that people such as myself have been hanging onto for lack of any more recent phone to upgrade to. I have done one battery replacement last year on my SE and its battery health is currently at 89%, I get one hour 40 minutes of screen time per day before battery hits 10% almost all of that being simply reading email and news on wifi. I've preordered the mini, if I can get two hours a day of screen on time or more for similar types of activity, I'll be fine with this. For times when battery life is more important than size and weight, I could just carry around an external battery to recharge it with. But I won't, because for me size and weight are paramount and I'll accept whatever other sacrifices come with that. On the other hand, if another vendor makes a nice phone that is small and light and also gets better battery life, then I would switch in a heartbeat. However there doesn't seem to be a single competitor in this space at the moment. If I were an android phone vendor with no product in this part of the market, I'd be flooding social media with negativity about the small size phone that I'm unable to offer.

Im excited - even though I know it will do exactly what my phone does now. I don’t use it for gaming or watching media, so think I can stretch out the battery. Plus I have an Apple Watch so I don’t need to check it as much.
You and I have the same type usage pattern. I am crossing my tech fingers that Apple releases a Smart Battery case for the mini. It would be good to have just in case.
 
yeah but it was a bigger LED screen , that's no where near the oled quality or res / DP you get with the 12 mini
I really doubt the average consumer cares one lick if it's OLED or LED, nor would they be excited about paying $130 more for a phone size that was $699 last year.

this is like the XR failure with pricing it at $750. I know this because the 11 priced at $699 with TWO cameras sold like crazy last year.

(don't get too uptight.... not that you would necessarily :) I know these are generalizations...)

I turned the Covid setting off a long time ago, but maybe there's still some data collection happening?
 
How dumb are these guys? Why is it so hard to understand: The small size is the value here.
They're reviewing for the average consumer... average consumer compares to last year's phones.
11 sold like gangbusters because of the perceived value: TWO CAMERAS!!! $50 less than last year!!!
 
The Mini has a smaller battery, but may get battery life on par with the XS it’s effectively replacing as the “small” iPhone (with no home button).



I recommend watching Dave Lee's video about iPhone 12 mini - he tries to make battery life benchmarking with some interesting results (for example showing how light/dark textures are important for battery life in phones with OLED screens):
One interesting thing about this review is that it is yet ANOTHER review where the 12 Pro was found to have worse battery than the regular 12, despite being nearly identical.

Must be the extra 2GB of RAM. 🤷🏻‍♂️
 
I really wish Apple would realize that for many people, an extra 1-2 mm of thickness would not be an issue if it meant realistic all-day battery life.

Thinner-and-lighter is directly at odds with battery life in this post-removable-battery world, and not having a battery that lasts all day makes for bad user experience.
For me small and light go together and of the two, it is the weight that is the most important aspect. The 12 mini is just barely acceptable at 133g (outside the US), remember it's battling against the original iPhone SE that people are still using, at 113g. I'd also be willing to pay a lot extra for a case made of lightweight composites to get the weight down, aluminum and glass are heavy so why use them except where there is no choice (such as the actual display surface)? Adding 10g to the weight would make this phone a non-starter for me, there are competitors in that 'porky smaller than average smartphone space' but none since the SE in the compact space and this one just barely qualifies.
 
That's very good news for airplane travelers who pre-load videos to watch on long flights.
On the last 2 long flights I was on (pre-Covid), the seat backs had USB charger outlets. Lots of kids watching their video with their iPads plugged into those outlets during the long flight.

So, on long flights, remembering to bring a USB-to-Lightning cable is more valuable than a heavier battery.
 
However, this brings up an interesting question: Should there exist an iPhone mini Pro?
If you look at processor performance, ML performance, and the camera (except for telephoto), and compare those to last years 11 Pro. the 12 mini is already a Pro model. Unless you actually need and use the telephoto lens.

I looked thru all my past years photos, and only found 2 good shots that used the telephoto. Not enough to keep my from getting a 12 Mini instead of a Pro model this year. The best camera is one that's with you, and the 12 mini fits in more of my pockets, and thus is less likely to left on the desk or inside a bag.
 
Will turning off 5G have a significant impact on battery performance? I know it's one of their big selling points - I just don't need it.

It's a small phone aimed at light users, I don't think battery life will be much of an issue for Target Audience. Personally I am so happy with the iPhone 11 Pro Max. its a game changer where I can use it as much as I want and never worry about running out. I don't want to go back to the old days of having to be careful and curtail my use.

Can you turn off 5G altogether? So it doesn't even try to get a 5G signal and sticks with 4G? That would help battery life a lot.
 
I'll bet I'm not alone in wanting to use my phone less, not more. Smaller screen and battery mean more incentive to put the phone away except for things I really need it for. I was actually intrigued by that tiny Palm phone last year, but that thing is just too extremely limited. The 5S is still my favorite iPhone (at the time of purchase), so the 12 Mini was an instant go for me. With OLED and killer cameras, I'm fully expecting this one to take the cake as my favorite. Can't wait for Friday!!

This was literally my exact reason for wanting a small phone again. I’ve actually stated this in other threads. Glad someone else has the same idea.

Apple has increase size and thickness of their phones basically every year since the iPhone 6. I don’t know why there is still this narrative of them prioritizing thinness over everything.
