We've heard plenty of rumors about the so-called iPhone SE 2 over the past year, and the latest suggests that the smartphone will gain a glass back, which would put it in on even footing with the iPhone 8 and iPhone X. This glass back will allow the iPhone SE 2 to support wireless charging, which Apple finally embraced in 2017 for its smartphones (the Apple Watch was the first Apple device to support wireless recharging).
Previous rumors claimed that the iPhone SE 2 will feature Apple's A10 Fusion SoC (which was used on the 2016-era iPhone 7 and iPhone 7 Plus), 2GB of RAM and a larger 1,700 mAh battery (up from 1,624 mAh for the current iPhone SE). The iPhone SE 2 will also allegedly be available in 32GB and 128GB capacities, leaving the larger 256GB SKU for the iPhone 8 and iPhone X.
There is absolutely no chance that the iPhone SE will gain the Face ID biometric authentication system of the iPhone X, although it will likely feature the second-generation Touch ID fingerprint sensor that graces the iPhone 8 and iPad family of devices.
The current iPhone SE has been in Apple's lineup since March 2016, and was added for customers that prefer a smaller form-factor (4-inch display versus 4.7 inches for the iPhone 6/6s/7/8). The iPhone SE also serves as Apple's cheapest smartphone, priced from $349. The next step up in the family is the iPhone 6s, which is priced from $449.
