Here are all the expected battery features of iPhone 16 models:

  • Bigger Batteries: The base model of the iPhone 16 is expected to come with 3,561 mAh, which is a 6.3% increase from 3,349 mAh on iPhone 15. However, contrary to other iPhone 16 models, the Plus has been downgraded by 8.6% with 4,006 mAh from 4,383 mAh on iPhone 15. Nonetheless, the biggest bump in the battery capacity is expected in the iPhone 16 Pro battery, with a battery capacity of 3,355 mAh from 3,274 mAh on the iPhone 15 Pro, a 9.2% increment.

Similarly, the iPhone 16 Pro Max battery life caters to users who heavily utilize features like photography and videography, which drains the battery faster.
  • Stacked Batteries: According to rumors, the upcoming iPhone 16 models will feature stacked battery technology, which is anticipated to improve energy density and battery life compared to the single-layer battery technology used in the iPhone 15 models.
  • Up to 40W Wired Charging: The iPhone 16 is expected to offer charging speeds of up to 40W using a USB-C connection. This is far faster than the up to 27W cable charging speed on iPhone 15 models, allowing you to charge your iPhone 16 in half the time.

Major Feature Updates to Influence iPhone 16 Battery

While a lot has been said and leaked about the upcoming iPhone 16, little has been focused on its battery features. To keep you informed about the new iPhone 16's battery features, we have compiled all the available leaks and rumors.

Here are some of the expected feature updates on iPhone 16 battery:

New Metal Casing Design

Apple is rumored to apply a new design to its iPhone 16 batteries that could offer more energy density and battery life. One of the popular iPhone analysts, Ming-Chi Kuo, shared that Apple will adopt a new stainless steel metal casing for the iPhone 16 battery to increase cell density by around 5 to 10 percent. While this new design is expected to come in all iPhone 16 models, the iPhone 16 Pro Max battery life will majorly benefit from the denser batteries.

AI-Powered Battery Management

Apple says AI will significantly improve battery management in iPhone 16. The AI-driven power management system can analyze usage behavior and adjust power distribution to enhance battery life while retaining performance. Ultimately, the upcoming iPhone 16 is expected to have better battery management to optimize battery usage using AI technology.

New Battery Replacement Technology

According to the most recent report ahead of the iPhone 16 launch, one of the biggest changes to the battery system could be related to battery replacement methods. Apple is said to be planning to introduce a new technology to simplify iPhone 16 battery replacement to comply with the new EU smartphone battery law. The new law requires smartphone manufacturers to allow users to easily access and replace batteries with tools by 2025.

The method to replace iPhone batteries is rather difficult, involving adhesive strip removal. Apple seems to be encasing the battery in metal, which can be dislodged easily with low-voltage electricity to remove it. However, Apple still maintains that using professional experts is necessary to replace batteries on iPhones.

Better Heat Dissipation

Learning from the previous model's heating issues, which resulted in thermal throttling, Apple is expected to apply new technology for better heat dissipation in iPhone 16 models. The new metal design and graphene layers on the iPhone 16 Pro models are introduced to help keep the phone cooler while charging.

What Are Users' Expectations For iPhone 16

Since the new iPhone 16 was announced, it has been buzzing with rumors, leaks, and expected upgrades. Most online communities on Reddit, Quora, and other platforms have focused on the new A18 chip, new display sizes, and upgraded cameras. Seldom was anyone talking about battery improvements in the iPhone 16 until one user leaked the expected battery capacity.

It was a surprise revelation, as many users were expecting at least 20% to 30% increased battery capacity on the new iPhone 16, as battery life on previous models has been an issue. However, Apple says that with high energy density, a new battery design, and power-efficient processors, the iPhone 16 battery life is expected to be much better than the iPhone 15. This can only be verified once the phone is released in the coming Fall.

Overall, there has been a positive response to the rumored battery improvements on the iPhone 16. Users are anxious for more consistent battery performance but are concerned about potential compromises in size and weight.
