Hello team,

Been playing around with the new iPhone 16 Pro Max, and the battery is superb, probably off the charts [with Low Power mode on work days i can stretch 39-40 hours of some use here and therebefore recharging which is absurd]. However I did find this option called "charge limit" on battery section - which was never present in the last phone before upgrading [11 Pro Max]

long story short i have had that 11 Pro Max for 5 years and obvs capacity dropped a lot [74-75%] due to heavy use.

Personally would I be better off leaving charge limit at 80-95% ish or just leave it at 100% and run the full cycle vice versa and optimised charging on etc.

Just like the 11 Pro Max, I'd 'most likely' hold onto the 16 Pro max for 4-5 years, unless there's something gamechanging but with the efficiencies and the huge gains in battery life on th 16 Pro Max could possibly stretch it even longer/further till no OS updates left.

That said budget isn't an issue and i'm definitely not the type to 'upgrade every two years now... phone barely moves up in new features hence the longer keeping time'

As this phone has insane battery life I normally tend to run it now between 95-100% to 5-10% before recharging [which means i can wait till the next morning to recharge instead of doing it overnight now]

If you’re using 85-95% battery daily, then you really don’t have enough room to conveniently employ better battery management options. I personally rather pay for an Apple battery swap, than have to plug-in more than once/day.

FWIW, I have an unusually efficient usage pattern (mostly lite apps and wi-fi), and have efficiency-tuned my settings, which creates a lot of excess capacity/room, and then use a custom charge optimization (shortcut automation + smartplug) with good results on a 5yo XR. Plan on an iPhone17.5 next, then the XR will move to motorcycle MP3 for another 6.5yrs, retiring my previous iPhone5 at 13yo.

Unfortunately, Apple’s battery mgt options are dumbed-down and miss some easy low-hanging fruit.
