"My was one of the first to roll off the production line and into people's hands on launch day. Since I'd spent the previous two years absolutely babying the battery in my iPhone 15 Pro Max, I decided to take a different approach this time around. Also: After charging my iPhone the 'Apple way' for 2 years, here's the state of its battery now I don't think it has made any difference."
"As of today -- Feb. 7, 2026 -- my new iPhone has been through 122 recharge cycles over the past 140 days. I've had the charge limit disabled so every charge goes to 100%, and I've had Optimized Battery Charging disabled. My iPhone can't seem to figure out my schedule, as I'm somewhat erratic and don't need an alarm most of the time about 6 a.m."
A launch-day iPhone experienced heavy, real-world use including 122 recharge cycles over 140 days. The charge limit was disabled so every charge reached 100%, and Optimized Battery Charging was disabled. The handset saw both wired and wireless charging, varied chargers and power banks, temperature extremes, occasional full discharges, and prolonged connection to chargers while kept in a thick heat-retaining case. Despite this treatment, reported battery capacity remained at 100%. Modern lithium-ion batteries tolerate substantial abuse. Battery health commonly stays at 100% for the first months, with an expected decline of roughly one percentage point per 50 recharge cycles.
