O iPhone Duo will officially arrive in stores this Friday, October 23, and in the meantime begin to circulate some official information about the phone specifications – as is the case of the battery that can be found inside.
Account macromors website that the iPhone Duo has a 4,883mAh battery divided into two parts, which has a 51-hour autonomy for each cycle. The available information also indicates that the battery will maintain its original performance for at least a thousand charging cycles.
Shared information indicates that for video playback, the iPhone Duo can be used for 44 hours on the external screen for 31 hours on the internal screen.
It is important to mention that the iPhone Duo is Apple's third phone with the highest battery capacity, just behind iPhone 17 Pro Max (with 5.088mAh) and iPhone 18 Pro Max (with 5.567mAh).
With the launch of the iPhone Duo scheduled for the end of this week, we won't have to wait much longer to know what we can do with Apple's first foldable phone.
You'll have to wait for 2027 to buy the iPhone Duo
The first to order the iPhone Duo will be able to start using it on the release date, scheduled for October 23rd. However, everyone else will have to wait a little longer.
This is because, as Apple's online store in Portugal indicates, those interested in purchasing the iPhone Duo are currently having a delivery forecast only for early 2027 – more precisely for January 22nd.
It is worth remembering that the iPhone Duo was announced in September such as iPhone 18 Pro and iPhone 18 Pro Max. These top-of-the-line models have already been launched on the market, with the release of this foldable to have been pointed towards the end of October.
It is also important to remember that before the pre-sale period of iPhone Duo began, Apple decided to increase the production goals of the foldable. Instead of the 6 to 7 million that would be produced by the end of 2026, 10 million units will now be produced.
The decision will have been taken after Apple has verified a consumer interest above expectations and, given the waiting period for iPhone Duo, the membership of those interested in buying the fold seems to have proven that the strategy was the right one.
Remember that iPhone Duo will be available in a 256GB base version for the price of EUR 2,399. The foldable will also be available in 512GB versions for 2,649 euros, 1TB for 3,149 euros and 2TB for 3,899 euros.
The delivery forecast for new orders from iPhone Duo seems to be across all these storage settings. This means that regardless of the configuration you choose for your iPhone Duo, you will still have to wait until the beginning of 2027 to start using your phone.
Of course, this information is not enough to be sure about the success that iPhone Duo will have. However, the fact that sufficient purchases have been made so that new foldable orders are not satisfied until 2027 is a good indicator that the membership of iPhone Duo may be to Apple's liking.
