The voltage required for stable operation is determined by the frequency at which the circuit is clocked, and can be reduced if the frequency is also reduced. Voltage is therefore the main determinant of power usage and heating.

f, where C is the capacitance being switched per clock cycle, V is voltage, A is the Activity Factor indicating the average number of switching events per clock cycle by the transistors in the chip (as a unitless quantity) and f is the clock frequency.

The dynamic power ( switching power) dissipated by a chip is C See also: Processor power dissipation § Sources Automatic overclocking (boosting) is also technically a form of dynamic frequency scaling, but it's relatively new and usually not discussed with throttling. Processor throttling is also known as "automatic underclocking". The combined topic is known as dynamic voltage and frequency scaling ( DVFS). after poor overclocking).ĭynamic frequency scaling almost always appear in conjunction with dynamic voltage scaling, since higher frequencies require higher supply voltages for the digital circuit to yield correct results. Dynamic frequency scaling helps preserve battery on mobile devices and decrease cooling cost and noise on quiet computing settings, or can be useful as a security measure for overheated systems (e.g.

JSTOR ( September 2021) ( Learn how and when to remove this template message)ĭynamic frequency scaling (also known as CPU throttling) is a power management technique in computer architecture whereby the frequency of a microprocessor can be automatically adjusted "on the fly" depending on the actual needs, to conserve power and reduce the amount of heat generated by the chip.

Please help improve this article by adding citations to reliable sources. The new Optimized Charging FeatureĪpple released another battery-focused feature in iOS 13 called “Optimized Battery Charging.” The feature reduces the wear on your iPhone battery and improves its lifespan by reducing the time your iPhone takes to charge fully.This article needs additional citations for verification. After all, $49-$69 is a lot lower than the price of a new iPhone. If you own a reasonably modern iPhone, like the iPhone 8, battery replacement may make more sense than buying a brand new iPhone. Instead of buying a new phone, another affordable option is to replace the battery for $49 or $69, depending on which model you own. However, this will shorten your battery's lifespan. If you prefer performance over extended battery life, then switching off the performance management makes sense.

If you are on an iOS older than version 11.2, you’ll have to perform more than one update to bring your phone up to date.

The “Software Update” screen will either tell you whether you have the latest iOS installed or prompt you to upgrade to the newest iOS.Under “General,” tap on “Software Update.”.Here’s how you can upgrade to the latest iOS on your iPhone:

Once the battery reaches a certain threshold, your iPhone might also randomly turn off after a few hours of usage. The iPhone’s battery capacity reduces with each charging cycle and gradually loses its ability to offer peak power.

While it’s no fun to suddenly have your iPhone running at a fraction of its power, there’s a good reason why Apple throttles its iPhones past a specific age. If a CPU is not adequately cooled, it can lead to poorer processing performance in a process known as ‘thermal throttling’ - the cooling system here throttles the CPU. For example, a higher-performance computer usually requires a robust cooling system in order for the CPU to operate at maximum capacity. Apple once introduced this on MacBooks to stop them from overheating, but iPhones can also be throttled to preserve battery life.Įlsewhere in computer hardware, throttling can also be a term used to refer to computer components limiting the performance of other components. Theoretically, this will prolong the device’s lifespan - allowing it to function at a usable level for a longer period of time.
