The verdict, & two little voices
Should you actually get the 128 GB Apple iPhone 15 Plus on AT&T?
The editor weighs in — flanked by the optimist on her shoulder and the cynic on the other.
“The 4383 mAh battery makes a long day, a travel day, or a charger-free day less of a calculation.”
“Apple built a 6.7-inch OLED and chose 60 Hz - Android competition at this price has offered 120 Hz for years.”
