Apple's upcoming standard Apple iPhone 18 could get a surprisingly big battery upgrade, potentially making it better than the Apple iPhone 18 Pro in one important area. A new leak suggests that the iPhone 18 could feature a 4,430mAh battery, compared to the reported 4,288mAh battery on the eSIM-only iPhone 18 Pro. However, these are still unconfirmed specifications, and the actual battery capacity could vary depending on the market and SIM configuration.
iPhone 18 Battery Could Be 20% Bigger Than iPhone 17
According to the leaked information, the iPhone 18 could pack a 4,430mAh battery, compared to the 3,692mAh battery inside the Apple iPhone 17.
This represents an increase of approximately 20%. Interestingly, the reported capacity is also higher than the 4,288mAh battery found inside the US eSIM-only iPhone 18 Pro.
Here is how the reported battery capacities compare:
iPhone model | Battery capacity |
|---|---|
iPhone 17 | 3,692mAh |
iPhone 18 (leaked) | 4,430mAh |
iPhone 18 Pro (US) | 4,288mAh |
However, there is an important detail for Indian buyers. The larger battery figure could be associated with an eSIM-only version without a physical SIM tray. Apple typically offers different battery capacities depending on regional SIM configurations, so the Indian variant may not get the same 4,430mAh battery.

iPhone 18 Expected Specifications and Upgrades
The battery is not the only expected upgrade. According to the leak, Apple could retain the 6.3-inch ProMotion display with anti-reflective coating and a resolution of 1206 x 2622 pixels.
The smartphone is also expected to feature Apple's next-generation A20 chipset, reportedly manufactured using a 2nm process. This should bring improvements in performance and power efficiency over the A19 chip inside the iPhone 17.
Other expected upgrades include:
- Processor: Apple A20 (2nm)
- Display: 6.3-inch ProMotion display
- RAM: 9GB, up from 8GB
- Modem: Apple C2 modem
- Rear Cameras: 48MP primary + 48MP ultra-wide
- Front Camera: 18MP
- Battery: 4,430mAh (leaked)
- Charging: 40W wired and 25W wireless
- Water Resistance: IP68
The camera hardware is expected to remain largely unchanged in terms of resolution. However, the new processor and other internal improvements could bring additional performance and photography enhancements.
The 9GB RAM upgrade has also been reported previously by Apple analyst Ming-Chi Kuo, who expects the standard iPhone 18 models to receive more memory for upcoming Apple Intelligence features.

iPhone 18 Price and Launch Timeline
Apple has not announced the iPhone 18 yet. Current reports suggest that the standard iPhone 18 could launch in early 2027, rather than alongside the iPhone 18 Pro models.
The leaked information also mentions an expected starting price of $999. However, this pricing is not confirmed, and the final price could change before launch.
For now, the bigger battery appears to be one of the most interesting upgrades coming to the standard iPhone 18. If Apple manages to deliver a larger battery alongside its more efficient 2nm A20 chipset, the phone could offer a noticeable improvement in battery life over its predecessor.
We will have to wait for more reliable leaks and Apple's official announcement to know the final specifications.
