Teacher: sorry for the late response to your post. I own an IPone SE 2nd or 3rd Gen. (I’m not sure which at this moment.) I regard a spare battery as an EDC essential. I also want a screen protector and protective phne case. My solution is a BOPPS auxiliary battery phone case and a Zagg screen protector , with life of the phone free breakage replacement warranty for the purchaser.

The BOPPS CASE ( ~$30 ) is an Amazon Best Seller and adds about an 150% recharge capability. It is fairly lightweight and based on my own Chinese, I can attest that it and the ~$18 Zagg screen protector, together , have allowed my phone to survive, without damage , several +3’ falls onto ceramic tile floors and pavement. In my multiple experiences. , Zagg has been good to its warranty, making replacement very easy.

Usual disclaimers regarding my lack of connection to BOPPPS and Zagg.
