The Galaxy S23 series has been a massive hit for Samsung. All the phones in the lineup offer excellent performance, consistent camera quality, and long battery life. After the poor battery life seen on Galaxy S20 and Galaxy S22 series phones, the Galaxy S23 has been a welcome change. However, Apple is still in the lead and could extend that lead later this year with the iPhone 15.
It is being reported that Apple is increasing the battery capacity across all its upcoming iPhone lineup. According to ITHome, the iPhone 15 will feature a 3,877mAh battery, while the iPhone 15 Plus will be powered by a 4,912mAh battery. The iPhone 15 Pro and the iPhone 15 Pro Max reportedly have 3,650mAh and 4,852mAh batteries, respectively. Compared to the iPhone 14 series devices, the iPhone 15 models will have 12-18% bigger batteries, which could result in much longer battery life, especially when these devices are expected to feature more power-efficient 3nm chips.
The Galaxy S23 has a 3,900mAh battery, while the Galaxy S23+ has a 4,700mAh battery. The Galaxy S23 Ultra has a 5,000mAh battery. While these phones offer good battery life in the Android segment, they still can't match the iPhones in terms of web browsing and mixed usage due to the chips and the differences between Android and iOS.
iPhone 15 vs. Galaxy S23 battery capacities
| Phone | Battery Capacity |
| iPhone 15 | 3,877mAh (18% bigger than iPhone 14) |
| Galaxy S23 | 3,900mAh |
| iPhone 15 Plus | 4,912mAh (13% bigger than iPhone 14 Plus) |
| iPhone 15 Pro | 3,650mAh (14% bigger than iPhone 14 Pro) |
| Galaxy S23 | 4,700mAh |
| iPhone 15 Pro Max | 4,852mAh (12% bigger than iPhone 14 Pro Max) |
| Galaxy S23 Ultra | 5,000mAh |
Galaxy S24 also rumored to feature 4nm chips
The Galaxy S24 series is rumored to feature 4nm chips. In some regions (Africa, Asia, and Europe), the Galaxy S24, Galaxy S24+, and Galaxy S24 Ultra could use the Exynos 2400, and in the US, they could come equipped with the Snapdragon 8 Gen 3 processor. Since they aren't expected to use a 3nm chip like iPhone 15 series, we don't expect them to last as long as the upcoming iPhones.
Samsung should think about how it can improve the battery life on its phones to keep up with iPhones. The ideal way would be to work with Google to make changes to Android or make really power-efficient chips by using Samsung Foundry's second-generation 3nm fabrication process that was recently announced.
