i-Phone Bar issue with good signal strength

Hi Experts
We are having issues like Apple I-phone is having good signal strength like -80 dbm with showing 2 bars in LTE and it is happening across network, we checked even two handset at same spots and this is not the case of other android handsets. if anyone has faced and mitigate the issue. please share thoughts on this.

Thanks in advance

Strongly agree to share issue with Apple directly. Most likely this is SW issue
