Rumor claims iPhone 15 battery boost is inbound this fall

Apple may increase the size of the batteries used in the iPhone 15, with each version rumored to get a big jump in capacity versus the iPhone 14 counterpart.

Apple prides itself on offering all-day battery life for its devices, including its flagship item, the iPhone. While the storage improvements in the iPhone 14 series weren't huge compared to the iPhone 13, it is claimed that the iPhone 15 will enjoy a considerable power boost.

According to a Weibo posting in a report from ITHome, the iPhone 15 generation will gain between 350mAh and 600mAh in battery capacity across the board.

The iPhone 15 will grow from the 3,279mAh unit in the iPhone 14 to a 3,877mAh version, the report alleges. For the iPhone 15 Plus, the battery will increase from 4,325mAh to 4,912mAh.

On the Pro model side, the report alleges the iPhone 15 Pro will get a 3,650mAh battery versus 3,200mAh in the iPhone 14 Pro. Lastly, the iPhone 15 Pro Max will apparently use a 4,852mAh battery instead of a 4,323mAh variant.

By contrast, the iPhone 14 Pro saw a 105mAh year-on-year increase, the iPhone 14 a 52mAh increase, and the iPhone 14 Pro Max a 29mAh decrease.

While higher capacities is always a good thing to hear in rumors, the report itself states that the data may not be accurate. Also, the Weibo source, who claims to be a Foxconn insider, says the information is 80% accurate.

Normally, changes in battery capacities aren't necessarily going to benefit consumers directly, as the device itself may have different power requirements to previous generations. If the figures are true, it's likely that Apple will end up boasting about multi-hour improvements to battery life, especially if other power-saving features are introduced at the same time.

Wow, have been considering the 14 plus because of the battery and less weight than the Pro models. Look at the capacity estimate of the 15 plus.

Why? 15 Pro is about to get a 3nm chip using LESS power. Samsung reduced battery size from S21 to S22. Apple could do the same.
With 15 Pro being all about A17 there really is no reason to change design, display, or battery size this year.

Unless you work directly on the iPhone at Apple and here divulging design and production secrets there is no reasonable way you can know that there is “no reason” to make changes to the iPhone 15’s “design, display, or battery” and that Apple will only detail and promote they A17 chip as the only new feature this year in your “all about” comment.

What if, say, Apple improves the camera system in a way that will causes a much higher battery draw for video? Wouldn’t that warrant increasing the battery, if feasible, so that a video can be taken for a reasonable and expected duration? What if that camera change includes AR/VR capabilities to help promotes and benefit Vision Pro usage in a meaningful way? What if they’ve finally added downstream inductive charging to AirPods and Apple Watches? What if they finally added Touch ID behind the display and that extra substrate now requires a brighter backlight to achieve the same relative brightness? What if any number of other ideas?

The space to house a battery may need to increase, not because of a bigger battery but to include a magazine to comply with EU requirements for a user-replaceable battery.

Perhaps 3nm will lead to physically smaller chips (at least, their own ones) allowing for more battery space.

Combined with a lower power usage the net result might be several hours of extra battery, alway very welcome with a phone.
