[SOLVED] : The iPhone 12 Pro Max is said to have a smaller battery than its predecessor

The certification of the iPhone 12 Pro Max reveals that the smartphone would carry a 3687 mAh battery, a battery 7% smaller than that of the iPhone 11 Pro Max last year.

IPhone 12 Pro Max

Like every year at the time of the announcement of the new iPhones, Apple is at the very least laconic as to the full characteristics of its new smartphones. This was again the case last week, when the iPhone 12 mini, 12, 12 Pro and 12 Pro Max were presented.

The firm has unveiled the Apple A14 Bionic processor, the photo characteristics or the definition of the various screens, but once again remained discreet about the onboard RAM memory or the capacity of the batteries integrated into the various models.


While the first deliveries are expected this Thursday for the iPhone 12 Pro, we now know a little more about the battery used for the large-format model, expected in mid-November. The MacRumors site has indeed discovered the TENAA certification of the iPhone 12 Pro Max, necessary for its marketing in China. A certification showing the battery capacity of the smartphone. According to the document, the phone should carry a 3687 mAh accumulator.

For comparison, last year’s iPhone 11 Pro Max had a 3,969 mAh battery. The new iPhone 12 Pro Max therefore incorporates a battery with a capacity reduced by 7% compared to the previous model. A difference that can be explained by the more compact format of the new model, with dimensions of 7.4 x 78.1 x 160.8 mm against 8.1 x 77.8 x 158 mm for the iPhone 11 Pro Max .


Note also that the battery capacity is not everything in terms of autonomy and that software optimizations can promote better battery management. Still, with a larger screen and a definition that has been revised upwards, we imagine that the smartphone will not make a significant gain in terms of autonomy.

On the RAM side, we already learned last week that the two iPhone 12 Pro and 12 Pro Max would benefit from a gain in terms of memory, with 6 GB. A choice justified by the more advanced performance in photo and video.

The iPhone 12 Pro has been available since Thursday, while the 12 Pro Max will arrive on November 13, after pre-orders that will open on November 6.

iPhone 12 and 12 Pro: inside, the same 2,815 mAh battery

The iPhone 12 and 12 Pro are available in stores and their shipments started last Friday. Thus, many journalists and amateurs analyze them from every angle. Debonings in due form have already taken place, to see what they contain inside. On the Chinese YouTube channel Io Technology, we can in particular see the two new iPhones being dismantled piece by piece.

This makes it possible to realize that they integrate the same battery component, that is to say a block of 2,815 mAh.

Remember that the iPhone 11 and 11 Pro are respectively equipped with a battery of 3 110 mAh and 3046 mAh. However, on paper, as seen there, the iPhone 12 is supposed to last longer than the iPhone 11, while it would be the opposite for the iPhone 12 Pro.

The theoretical decrease in autonomy for the iPhone 12 Pro is understandable as a result, given that the latter incorporates a battery of lower capacity than its predecessor. For the iPhone 12, on the other hand, it would gain in autonomy over the older generation, yet with a smaller capacity battery. The switch from LCD on iPhone 11 to OLED screen technology on iPhone 12 could be the main explanation for this improvement. Indeed, the OLED consumes less energy than the LCD. This is mainly due to the fact that on an OLED screen, a black pixel is an off pixel.

For the iPhone 12 mini not yet available, we would also know the battery capacity, ie 2,227 mAh. According to Apple, this model should perform better in battery life than the 2020 iPhone SE, but poorer than the iPhone 11.

Finally, it remains to be seen what the iPhone 12 Pro Max is capable of, with a battery that could reach 3,687 mAh. With its large 6.7-inch screen, it will only be marketed from November 6 for pre-order and November 13 in stores, like the iPhone 12 mini.

The iPhone 12 Pro Max has a significantly smaller battery than the iPhone 11 Pro Max

Certification documents reveal that the iPhone 12 Pro Max has a 3,687mAh battery, which is 7% smaller than that of the iPhone 11 Pro Max. Despite everything, the smartphone retains the same autonomy as its predecessor. Thanks in particular to an A14 chip in 5 nm and various optimizations.

As with every generation, Apple is reluctant to reveal the exact battery capacities of its iPhone 12. Fortunately, sooner or later, the data will appear in certification documents. After the battery capacities of the iPhone 12 and iPhone 12 mini, we now know the cell size of the iPhone 12 Pro Max. As expected across the range, capacity is down by 7% compared to the previous generation.

According to the Chinese TENAA database, the iPhone 12 Pro Max thus embeds a 3687 mAh battery against 3969 mAh for its predecessor iPhone 11 Pro Max. This significantly lower capacity is not directly related to autonomy. In fact, Apple has changed a lot of things inside the iPhone 12s.

The latter are notably equipped with an A14 Bionic chip engraved in 5 nm, which allows it to deliver increased performance while wasting much less energy. So, if Apple is to be believed, iPhone 12 Pro Max delivers 20 hours of video playback and up to 80 hours of audio playback.


This is strictly identical to the autonomy announced by Apple for the iPhone 11 Pro Max. At the time, the smartphone was crowned king of the autonomy market. In 2020, the autonomy of the iPhone 12, in particular the iPhone 12 Pro Max, should rather remain at the top of the basket, even if other competing options will undoubtedly do better on this point.

Everything indicates that Apple intended more to maintain a similar level of autonomy on this generation, rather than to really advance it. It must be said that even if Apple goes to 5nm, the inclusion of technologies like 5G complicates the equation.

Apple has also insisted on the fact that its new smartphones would go back to 4G as much as possible to avoid draining the battery too quickly. The next generation could be more an opportunity for improvements on this point, in particular thanks to a better mastery of 5G technology for which Apple had also acquired the portfolio of intellectual properties from Intel.
