With the iPhone 12 launching on Friday and in just a few hours to Australia and New Zealand, hands-on videos, teardowns, reviews, and other iPhone-related content has been coming out. A new teardown video delves into both the iPhone 12 and the 12 Pro, confirming battery life for both models and giving us a closer look at their internals.

The video from Io Technology is in Chinese, but YouTube’s auto-translated subtitles are quite accurate.​

Both the iPhone 12 and the iPhone 12 Pro have close to identical L-shaped logic boards inside, with the iPhone 12 Pro featuring an extra LiDAR connector for the LiDAR Scanner. The two phones also share a battery, and this teardown puts to rest rumors about the iPhone 12 Pro's battery capacity.

The iPhone 12 and iPhone 12 Pro have the same 2,815mAh battery inside, which explains why they offer identical battery life. There was some confusion over the battery capacity because leaked specifications in July had suggested the two models had 2,775mAh battery, but Brazilian specifications mentioned a 2,815mAh battery for the iPhone 12, so there was a possibility that the Pro model had the 2,775mAh battery we had been expecting, but that's not the case.

We now know the official capacities for each new iPhone in the lineup:
  • iPhone 12 mini - 2,227mAh
  • iPhone 12 - 2,815mAh
  • iPhone 12 Pro - 2,815mAh
  • iPhone 12 Pro Max - 3,687mAh
All of these batteries are smaller than the batteries that were used in the iPhone 11 lineup, with Apple possibly having to cut down on battery size in order to make room for 5G components and new camera technology in the Pro models.

The side-by-side teardown of the iPhone 12 and 12 Pro offers a good look at the similarities and differences between the two models. Both have smaller Taptic Engines and many other identical internal components. Though not shown in this video, a teardown from yesterday confirmed that Apple's iPhone 12 lineup is using Qualcomm's X55 modem.

The production quality of the video has really increased since last time they did a tear down.

This makes sense... I guess the pro may have lower real-world battery life due to the RAM bump and brighter screen, but I doubt it would be a noticeable difference to most people. (Also I think the aluminum design helps with cooling slightly more than the steel.)

In any case, these middle lineup phones are not attractive to me at all. There are only two phones I'm considering this year: mini and max... best size vs. best camera. I'm heavily leaning toward the mini, but will wait to see how good the max's camera is first. I had the XS max and didn't like the size very much, but I'm willing to put up with it if the camera is good enough.

I know Apple are fanatics about making thinner phones and they have done an amazing job of fitting so much technology in a small space, but a tinny bit thicker (flush to the camera bump) to have more battery capacity would be worth it.

More people fixated on the numbers: battery capacity rather than real world battery life and their actual needs. Sure, there are people who spend 10 hours a day streaming TikTok videos over 5G, but let them get a power bank and the rest of us save the extra cost and weight of a bigger battery we don't even need.

Why? it's about usage. If you want to watch TikTok all day on 5G (as was said in another post - really funny). The fact is that they have plenty of battery life. It's funny, because if you see the Samsmug reviews, they get excellent battery life if you put them in power save mode (60hz), but not so much at 120, but oh that so important to have buttery smooth scrolling. News flash, I've never had a problem with the scrolling on my iPhone X not being buttery smooth. Perhaps its useful for gaming or somthing, but buttery smooth scrolling - nah

What bothers me is they got rid of the L-shaped battery. Battery capacity seems to be down by 10% throughout the different models. It's kind of sad we regressed in battery life
check the specs, no regression in battery life

This suggestion has been made for years. No reason why they can’t but rather they won’t.

Im of the belief that it’s more of a design aesthetic at this point. That a protruding element adds character to an otherwise bland slab of glass. Just my guess.

Is there a regression? Apple lists battery life as the same for the iPhone 12 Pro and iPhone 11 Pro, other than a slightly lower video playback for the 12 vs 11 (up to 17 hours vs up to 18). Streamed video and audio playback are reported as the same. "Regression" battery life is likely going to be a 5G issue rather than an issue of the smaller battery capacity.

Of course, it would be nice to have even longer battery life but it looks like the 12 Pro will have essentially the same as the 11 Pro. That's impressive with a smaller capacity battery. It shows good progress in efficiencies. Again, if Apple had managed to keep a larger battery and have those efficiencies, that would have been amazing but Apple typically shoots for similar battery life year to year.

Why/how did the iPhone 12 get 10:23(4G) vs 12 Pro 11:24(4G) on Tom's Guide battery test though

2GB of extra RAM on the 12 Pro helped?

The battery life of the Nokia 6310i would be so, so welcome.

I can't remember quite how long it was - ten days or more?

Actually the battery inside the Nokia 6310 is only 1150 mah, way smaller than what we have right now. The difference is that with that type of phone, we just make calls and nothing else. Perhaps 1 or 2 quick messages but that's it.

This is quite common for Apple, from the 7+ to the 8+, the battery has also regressed.
