my phone is not charging fully only 85% battery is fine but how come the new version is not charging

Hello fitim010,

Thanks for choosing the Apple Support Communities. It sounds like your iPhone isn't charging fully. Sometimes this can happen when Optimized Battery Charging is enabled. below is how to turn that on or off.

About Optimized Battery Charging on your iPhone - Apple Support

1. Go to Settings
2. Tap on Battery
3. Tap on Battery Health & Charging
4. Toggle Optimized Battery charging off.

If that is already off, give these steps a try: If your iPhone or iPod touch won't charge - Apple Support

We hope this helps.

Cheers!
