Same here. Still having iPhone 13 PM & iPhone 11 on hand. Although switched to S23U, battery life I would say still iPhone 13 PM better but the charging speed in S23U is compensation of this.
What I missed from iPhone 13 PM?
- Better notification control, simple & straight forward. Two clicks for no sound & no vibrate, for this S23U, messy like hell.
- Notifications come in faster & more consistent, not like S23U hit & miss.
- Better battery standby times.
- App switching is smoother than S23U, app won't relaunch or delay like S23U.
- Some apps I'm using in iPhone is running well but when comes to Android keep giving me issues.
- Siri is far more better than Bixby, at least Siri can hear me well to dismiss the alarm when I'm on the bed 3 meters away. This S23U I screamed like hell also cannot hear.
- The Face ID, the best face regconization that can unlock the phone when u r wearing a mask or driving to do something on phone.
- The bottom navigation bar of Facebook.
- Ecosystem of Apple, Apple Watch & AirPod Pro & etc.
- Still cannot find a floating clock (悬浮时间) that I'm having in iPhone 13 PM which can customized alot & keep screen on when using.
- Better 3rd party app control in terms of battery usage & system standby.
What I liked about S23U?
- Camera features (Moon shooting, 100x zoom, night photos, Expert Raw).
- SPen for drawing & photo editing that need accurate position refinement.
- Better mobile & Wi-Fi reception than iPhone 13 PM.
- Can install Macrodroid or use Routine to automate most of my tasks. Unlike iOS shortcut which is limited & restricted.
- Enabled call recording by changing CSC.
- Navigation bar at bottom with NavStar enabled can customize shortcut.
- Good Lock with lotsa customization although still not 100% polished for One UI 5.1.
- Finally, I no need to use iTunes to upload my downloaded songs/rigntone/notification tones & organize them like hell.
- Car audio media & call separation, which you can control your phone audio only use for car audio instead media audio.
- Split screen, bubble conversation & pop-up window.
- Dual messenger
- Samsung Dex
- Fingerprint unlock when ur phone is on the table
In summary, no regret switched to S23U because I'm started to use to it.
Samsung keep copy iPhone. this is the reason iPhone user easy get to use it.
the most recent update, s23u no need go to camera VR mode to get measurements app. kudos to Samsung. now Samsung have a standalone app for measure.
