Since September 2024, my iPhone 16 Pro Max has been constricted to an 80 percent charge, with nary cheating. As of today, my battery's maximum capableness is astatine 94 percent with 299 complaint cycles.
With past year's test, I spent a batch of clip with my artillery beneath 20 percent. I saw immoderate comments suggesting that draining it truthful debased could besides impact artillery capableness implicit time, truthful this year, I tried hard to support my artillery betwixt 20 and 80 percent. I wasn't ever successful, but my iPhone 16 Pro Max was successful that mediate complaint country astir of the time.
You tin comparison your ain artillery wellness with mine, but my conjecture is that my 94 percent artillery capableness is astir average, careless of whether charging limits are connected oregon off. In fact, my iPhone 15 Pro Max was besides astatine 94 percent capableness astatine the 12 period people erstwhile I did this aforesaid trial past year.
I did a premix of charging via MagSafe and charging with USB-C, and my iPhone 16 Pro Max tin get blistery erstwhile charging implicit MagSafe, particularly with MagSafe artillery packs. Since I was trying to support supra a 20 percent charge, I did much wireless charging erstwhile I was out. I can't assistance but wonderment if vigor was an contented this year.
It continued to beryllium inconvenient limiting my iPhone artillery to an 80 percent charge. It was good erstwhile home, but if I was retired and wanted to usage the camera oregon needed GPS, it often wasn't capable battery. When you acceptable an 80 percent complaint limit, the iPhone volition complaint to afloat each truthful often to calibrate, and I appreciated astonishment days with 20 percent other battery.
If I had to guess, I astir apt had a 50/50 divided betwixt MagSafe charging and accelerated charging with USB-C. Most charging was indoors astatine astir 72 degrees, but determination were times erstwhile I was outdoors with a artillery battalion successful warmer conditions.
I usage my older iPhones for bundle tests, truthful my iPhone 15 Pro Max is inactive around. At the 2 twelvemonth mark, its capableness is 88 percent, down from 94 percent successful September 2024. It has 352 cycles, and I've kept it astatine the 80 percent limit.
During this year's testing, my iPhone 16 Pro Max artillery was inactive astatine astir 98 percent conscionable a mates of months ago, truthful I thought the bounds was having much of an impact, but I saw a decent driblet arsenic we got person to September. It was adjacent astatine 95 percent astir a week ago, but present I'm down to 94 percent.
I present person 2 years of information with my iPhone constricted to an 80 percent charge, and I don't deliberation it's been worthy it. My coworker who besides has a 16 Pro Max did not person an 80 percent complaint bounds set, and his artillery capableness is 96 percent with 308 complaint cycles.
Maybe mounting an 80 percent bounds improves artillery wellness implicit a longer play of time, but implicit a one-year period, the results person been disappointing. Setting charging to a 90 oregon 95 percent mightiness marque much sense.
I person upgraded to the iPhone 17 Pro Max and did already bounds it to an 80 percent complaint for different 12-month test. I'm funny to spot however the larger artillery changes things, and whether the power to aluminum volition marque a difference.
What's your iPhone artillery capableness and rhythm count? Let maine cognize successful the comments below, and measurement successful connected whether you deliberation the 80 percent complaint bounds is simply a bully idea.
