For the past 3 years, I've utilized that mounting connected my iPhone. I started with the iPhone 15 Pro Max, past did the iPhone 16 Pro Max, and astir recently, the iPhone 17 Pro Max.
After 12 months astatine an 80 percent maximum charge, my iPhone 17 Pro Max is astatine 97 percent maximum capacity with a rhythm number of 277.
Last year, my iPhone 16 Pro Max was astatine 94 percent capableness aft 12 months, and successful 2024, my iPhone 15 Pro Max was besides astatine 94 percent capacity.
During the twelvemonth I tested the iPhone 16 Pro Max, I tried not to fto the artillery dip beneath 20 percent. This year, I did the aforesaid thing, but I besides tried to bash much charging implicit USB-C than Qi2 oregon MagSafe. I'm not definite if that helped, but 97 percent capableness is the champion effect I've had yet with the complaint bounds turned on.
I don't cognize however my artillery effect compares to others, but if you've kept yours astatine 100 percent, you tin comparison your capableness to excavation to spot if there's immoderate existent difference.
Apple transitioned to aluminum and added vapor enclosure cooling with the iPhone 17 Pro Max, and I did deliberation my iPhone spent little clip uncomfortably lukewarm than the iPhone 16 Pro Max. It whitethorn beryllium that the vapor enclosure cooling made the biggest quality and limiting wireless charging didn't matter.
I don't usage the iPhone 15 Pro Max oregon the iPhone 16 Pro Max arsenic my main iPhones anymore, but I bash usage them regular arsenic trial devices. They inactive person the 80 percent bounds turned on, truthful I tin stock immoderate longer-term artillery results.
- iPhone 15 Pro Max (36 months) - 88%, 369 cycles
- iPhone 16 Pro Max (24 months) - 93%, 343 cycles
- iPhone 17 Pro Max (12 months) - 97%, 277 cycles
Last year, my iPhone 16 Pro Max deed 299 cycles by September 24. This year, I'm lone astatine 277 cycles. It's astir 2 weeks aboriginal than I usually study results too, truthful the larger artillery meant little charging.
The iPhone 17 Pro Max has a bigger artillery and faster charging than the iPhone 16 Pro Max, truthful an 80 percent complaint bounds wasn't arsenic hard to unrecorded with arsenic it was successful the past. I seldom ran retired of battery, though I did inactive bring a artillery battalion with maine astir places. My favourite artillery packs close present are the ones with built-in USB-C cables, particularly those that tin connect to my iPhone magnetically but complaint it implicit USB-C. It's faster charging that's inactive convenient. I besides proceed to beryllium a instrumentality of the super-slim artillery packs that adhd small bulk and value to an iPhone.
For the iPhone 15 Pro Max and iPhone 16 Pro Max, I didn't deliberation sacrificing a 5th of my artillery was worthy the capableness I ended up with, and that's inactive mostly the case. I'm guessing my 97 percent capableness isn't excessively acold disconnected from the artillery wellness readings connected iPhones that didn't person the complaint bounds turned on.
As for older devices, my two-year-old iPhone 16 Pro Max lone mislaid 1 percent capableness from 2025 to 2026, and my iPhone 15 Pro Max didn't suffer immoderate capableness astatine each during the year. Both phones had less artillery cycles (44 and 17, respectively), but they're holding capableness adjacent aft sitting dormant for abbreviated periods of clip passim the year.
The astir hands-off mode to negociate artillery wellness is to usage Optimized Battery Charging, since it minimizes clip spent astatine 100 percent artillery portion inactive charging to full. Setting an 80 percent bounds and past turning it disconnected connected days you request 100 percent is besides a bully compromise that could prevention you artillery capableness implicit time. Apple has 90 and 95 percent options too, which mightiness beryllium a amended choice.
My iPhone 18 Pro Max is already acceptable to 80 percent, truthful I'll cheque successful again successful September 2027. I'm going to instrumentality with USB-C charging erstwhile I can, and I'm funny however the adjacent bigger artillery volition impact longevity and what the 80 percent bounds is similar time to day.
What's your iPhone artillery capableness and rhythm count? Share it successful the comments beneath and measurement successful connected whether you deliberation artillery complaint limits are worthwhile.
