TheiPhone 15 ProandiPhone 15 Pro Maxboth have fantastic bombardment life . It ’s roughly the same as the iPhone 14 Pro and Pro Max from last year ( just slightly longsighted in our testing ) , but that shit them some of the longest - lasting high - end smartphones you could purchase .
But the non - Pro iPhones generally havelongerbattery life-time . We know that the high refresh charge per unit of 120Hz ProMotion display can have a significant impingement on bombardment lifespan which is one reason why Apple promotes theiPhone 15 Plusas experience the long battery biography in the lineup .
So naturally I wondered : if you stop your iPhone 15 Pro from going up to 120Hz , would itmake the battery last longer?After a few days of examination , I can confirm that itdoeshelp , but not enough to be worth it , with one exclusion : gaming .
Using Accessibility to limit ProMotion
Apple does n’t cater a way to disable ProMotion the iPhone Pro models . The show but dynamically adjusts refresh rate from 1 to 120Hz making alteration on the fly as determined by the system .
But youcanuse a setting in Accessibility to confine refresh rate to 60Hz , which will prevent the presentation from ramping up to those battery - run out eminent refresh rate . Of naturally , it also imply you do n’t get the smooth scrolling and animations of ProMotion , so you ’re giving up one of the primal features for which you buy a “ Pro ” iPhone . Perhaps if the battery life-time is much good , it will be worth it ?

To limit your iPhone 15 Pro ( or iPhone 14 Pro ) to 60Hz , openSettings , chooseAccessibility , then chooseMotion . Scroll down and start the option that saysLimit Frame Rate .
Does it make a difference?
Of of course , what I really want to sleep together is whether or not this makes a real deviation bombardment spirit . If you could get an extra time of day of CRT screen - on metre with Limit Frame Rate enabled , it may be worth giving up the additional suavity for some users .
I break away my stock stamp battery benchmark on both theiPhone 15 Pro and iPhone 15 Pro Maxwith this setting enable and handicapped . This consists of running the Geekbench 4 battery life-time trial with the presentation calibrate to 200 nit , with automobile - smartness and True Tone disabled .
It look like this settingdoeshave an impact , albeit a venial one . In two test per phone , I consistently saw a battery life improvement of around 5 percent . That something , but it ’s not the form of alteration that makes you need to give up the 120Hz smoothness for .
It ’s hard to recognize what the refresh rate is during the Geekbench 4 trial , which shows a relatively static sieve during the total benchmark , so I tried a few other tests . I scroll through Instagram and reddit ceaselessly , with very few pauses and the brightness crank up to about 70 percent . After 20 minutes , the battery indicant still read 100 % . After 30 instant , still 100 % . Somewhere between the 30 and 35 second mark , the barrage fire meter finally ticked down to 99 .
That result was consistent with or without theLimit Frame Rateaccessibility setting activated . At least when it comes to apps where you scroll through textbook and images , it appears that the dynamic nature of the frame rate has more to do with anything than whether the maximum is 60Hz or 120Hz . If there ’s a dispute , again , it ’s rather small .
Where it really matters: premium games
Many fluid game do not defend ProMotion , but a few of them do . ShootersCall of Duty : MobileandPUBG Mobilesupport gamey refresh rates , as do games like Brawl Stars , League of Legends : Wild Rift , Genshin Impact , Alto ’s Odyssey , and more . In most of these titles you have to start the in - game option to choose a particular 120fps or high frame rate fashion .
It ’s almost inconceivable to make consistently benchmark the difference in battery life during live gameplay – there are just too many variables . Still , in playing several of these games with the high frame rate options enabled for 20 minute at a sentence , I discover a pile less battery drain when I hadLimit Frame Rateenabled . Battery drain varies wildly from one game to the next , but it was n’t uncommon to have the shelling last twice as long withLimit Frame Rateoption enabled .
But then , plot developer already know this . That ’s is why it ’s almost always an option , and usually not the default setting . In fact , many game even offer 30fps limitation in their plot preferences , typically called “ Power saving manner ” or “ Battery living mood , ” even if the plot does n’t support ProMotion at all .
It ’s not just thedisplayuses more energy when a secret plan runs at higher frame rates , but the processor as well . This drain your battery a lot faster .
Our recommendation
We commend that most users calculate to simply confine assault and battery drain on their iPhone 13 Pro , 14 Pro , or 15 Pro should probablynotenable the Limit Frame Rate accessibility setting . The difference of opinion in battery life in most apps is minimal and not worth the tradeoff in smoothness .
In game , however , define frame charge per unit has a huge wallop , and it should be the first thing you examine if you ’re interested with battery life . But this is best execute within the game ’s optical preferences , which often allow for far more options than just a 60fps limitation .
