Greetings,

long time reader first time poster. I’m looking forward to the 5.4 inch iPhone 12 I think I will sell my 11 Pro and get one. I personally think the X, XS and 11 Pro are too wide which has made them kinda awkward to hold. I’ve had enough of big phones went from Galaxy Notes to the 11 Pro. I like that it’s smaller than most phones. I think the 5.4 is going to be a perfect size from all the leaked photos and schematics. My question is if the reports are true and the 5.4 has a 2,200mah battery what do people think it’s battery life will be like? The A14 and OLED screen should hopefully help I know it probably might not be as good as the 11 Pro’s but I hope it’s decent. Thanks for taking the time to read my post.

Cheers
 
I mean no one knows for sure. But my guess is it will last around the same time as the 11, maybe a hair more or less. But something in that ballpark.

Hard to say for sure. I suspect it won't be as good as anything in the 11 series. My guess is it will land somewhere between the 2020 SE and the 11.

I second this.

With the A14, and 400 more mAh than the iphone SE, my money is on 2-3 hours more than the SE; but definitely not equal to the 11.

But if Apple pulled that off? Wow!

The new A14 or whatever chip will be more energy efficient than the previous generation, so battery size won't be an accurate gauge for run time. Also battery run time is very dependent on the OS. If iOS 14 is a buggy energy hog (with all those home screen widgets) then whatever gains brought by the new chip might be consumed by the OS.

Per leaks the battery in the smaller 12 phone will be 2,227 mAh. Compared to the iPhone 11 at 3,110 mAh and the iPhone SE2 at 1,821 mAh it falls above the SE but still far from the 11.

Assuming that the combination of smaller, OLED screen and A14 will make the 5.4" iPhone 12 about 25% more power efficient than iPhone 11, that 2,227 mAh battery inside iPhone 12 would be roughly the equivalent of having 2,227x1.25=2,783 mAh battery inside iPhone 11. In other words, if iPhone 11 can do 17 hours of continuous video playback, 5.4" iPhone 12 would be able to do about 15-16 hours.

Thinking more about how newer processors can be more energy efficient... other than the two SEs, has Apple ever launched a new iPhone with an "old"/existing chip like they do with the iPads?
 
Despite the A14 being supposedly more efficient I, the fact that these devices will have 5G makes me doubt that the battery life will be as good as the 11 series. My feeling is that the 12 series will have decent battery life but not as robust as 11.

I fully expect the 13 series to bring back the legendary 11 series battery life.

I’m not saying your wrong. But seems crazy to release a new phone with worse battery life. I don‘t follow everything like some. But have they lowered the battery life in the past? I feel like its always got a little better.

Completely get you.

Between the iPhone 7/7 Plus to iPhone 8/8 Plus the battery size went smaller, however the 8 brought a chip that was 6nm smaller, so in terms of SoC the 8/8 Plus was quite a big jump from the 7 and so benefited greatly from more Power and Efficiency increases.

The move between 11 and 12 is just 2nm so the benefits may not be quite as clear when it comes battery consumption.

But who knows, maybe Apple is sourcing more power efficient displays and memory chips to.

5G still has a long way to go. I think Apple could get away with launching all/some of the 12 models with just LTE this year.

iPhone was late to 3G and LTE, and they still sold extremely well.

I agree. If Apple’s ecosystem wasn’t as strong as it is, I would think differently. I believe many forget that MacRumors is a very small niche world that isn’t really indicative of the whole of iPhone users. The fact that so many people hang onto their phones more than the tech obsessed MacRumors user shows just how solid the brand is, in many ways. I don’t think the non tech forum user is seeing 5G as a must have. They want their apps to work and they want their privacy.

you need to hope to have an iPhone 11 battery life and not like on the SE
SE is returning to the old days with iphone 5/6 battery life
iPhone SE has good battery life only on normal, basic usage, when you hit something harder bec of the chip that is so powerful and the battery capacity so low...it drain the battery pretty quickly
So i guess, the iphone 5.4" to have at least 2500mah and with that 5nm cpu can offer normal to good battery life no matter you do
 
The 5”4 iphone 12 is rumoured to have a 2,200 mh battery like other members have stated, which is about 400 mh more than the iphone SE, however it will need to power overheads like face id and a higher resolution screen. Hopefully the A14 bionics greater power efficiency will mitigate this somewhat, but im guessing battery life will be similar to the SE overall. This is fine for me as i get 2 days between charges on my SE as a moderate user, but heavier users of social media etc might suffer a bit.
 
the 2200mah its just a rumour or it was kind of confirmed with leaks pictures of the actual battery ?
2200mah for an 5.4" with oled for basic usage it will be very nice...but not for those who game on smartphones, if there are still any
So again, if you do a lot of gaming, video recording and battery is a main thing for you, avoid the 5.4" iphone with the 2200mh battery
I feel the 5.4" should have 2500mh to check all the usage for a good to great battery life
 
If some here are that concerned about battery size, wait for the iFixit tear down. I really don’t see how it is really that big of an issue in this day and age, when most of us have constant access to chargers and outlets. I think a lot of the worry is from people who want to be able to use their phone for 1 - 2 days without charging just to say they can.

Anker makes a charger that easily fits in your pocket and can charge the SE 2 times.

Trying to analyze what a rumored spec battery might have on the unreleased rumored phone is an exercise in futility.
