Is there a correct way to charge your iPhone? And what happens when you do? Here’s how mine has held up.
The battery in my 15 Pro Max was awful after 18 months of use.
I did everything Apple suggested to keep it in tip-top condition.
I’m going back to 100% charging with the iPhone 17 Pro Max.
When I got my iPhone 15 Pro Max in September 2023, I decided that I’d do everything I could to make the battery last. Well, an accident destroyed that handset, so I restarted the experiment in March 2024.
I wanted to see just how much lifespan I could get out of the battery. Battery life obsession
In my experience, no topic generates more articles, blog posts, and YouTube videos than how to get the best possible battery life from your iPhone, both daily runtime and overall lifespan. It’s also the topic on which I get the most questions and comments.
People have been obsessed with their iPhone’s battery life since day one, and the more metrics and tweaks Apple adds to iOS to delve into what the battery is doing, the worse it has become. Once Apple even added a feature that allowed users to cap battery charge levels to prolong the lifespan of their battery.
But if every minute of runtime, every percentage point of battery life matters, does it make sense to sacrifice 20% — or, to put that another way, one-fifth — of your battery’s capacity?
It seems that the iPhone’s longer battery life makes the tradeoff worthwhile. After all, Apple claims that iPhone 15 models and later can “retain 80% of their original capacity at 1,000 complete charge cycles under ideal conditions.” I was curious as to what “under ideal conditions” meant, but I was determined to give my battery the best chance possible.
