Teardown Video Confirms iPhone 12 and iPhone 12 Pro Use Same 2,815mAh Battery

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.

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.

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

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.
