iPhone 17 vs OnePlus Open

iPhone 17

The 3,692 mAh cell is up only marginally on the iPhone 16's 3,561 mAh, but the more efficient A19 chip and variable-refresh-rate display push the iPhone 17 to up to 30 hours of video playback (Apple's number) — eight hours more than the iPhone 16. Reviewers comfortably hit 5–6+ hours of screen-on time and end days with 15–25% remaining. Wired charging is 40W (50% in 20 minutes), wireless MagSafe is 25W. The OnePlus 13 and Xiaomi 15 still charge meaningfully faster, but versus other US-priced flagships this is competitive.

• After a week of use I'm consistently hitting more than six hours of screen-on time, with GPS, music streaming, and hours of doomscrolling — I have yet to find myself worried that my phone is going to die.
• Battery life has increased by 8 hours compared to the iPhone 16 — up to 30 hours of video playback versus 22 — and in normal use the iPhone 17 lasts about as long as the iPhone 16 Pro, from 8 a.m. to 6 p.m. with 20–25% left.
• I had 16 percent battery left by bed time after a 7AM-to-midnight day of email, Slack, music, calls, texting, Instagram and a few episodes of The Bear — with always-on display active the entire time.
