Although there is no guarantee that the FE version of the Galaxy S23 will be released, the leaked image of this battery is the first and strongest evidence to prove the existence of the S23 FE. Unfortunately, the battery capacity of this phone is not known.
Samsung will unveil the Galaxy Z Fold 5 and Z flip 5 folding phones and the Galaxy Watch 6 series at the Galaxy Unpacked event in early August. The Galaxy Tab S9 may also be introduced in this event. However, it is very unlikely that the Galaxy S23 FE will be announced at the Unpacked event.
The flagship killer of the Galaxy S23 series is expected to be announced in a sneak peek event or in a press release after the Galaxy Unpacked event.
