The jury is still out on that debate but in this case, it's quite the opposite as they're reducing
peak power draw in order to prolong a handset's life.
Apple's fix for this problem was to limit
the peak power draw that an older iPhone was capable of through software updates.
And as a reminder, this doesn't affect iPhone 8, iPhone 8 Plus, or iPhone X, which use a different method to manage
peak power draw, nor does it affect iPads, which have batteries so large it's unlikely they'd ever power down in face of powr spikes.
The XO - 1.75 and the XO - 3 tablet have a runtime
peak power draw in the 5W range and they idle even lower.
So
peak power draw only happens when charging a very low battery.
The XO - 1 and XO - 1.5 had maximum runtime
peak power draws in the 10W range.
Not exact matches
It turns out that Apple is limiting how much
power an iPhone processor can
draw in certain circumstances, therefore limiting the processor's
peak performance.
The system's three - ohm impedance allows it to
draw extra
power safely as needed for up to 640 W
peak power handling.
Plus, the
power draw at that
peak load is much higher and the amount of time spent in that mode is much greater than on a standard PC.»
For example, if you decrease sets, increase
power, and incorporate more explosiveness as your high priority races
draw near, you can allow your strength trained muscles to achieve
peak performance on race day.
The Jaguar F - Type Coupe R
draws power from a 5.0 - litre Supercharged petrol engine, having 8 - cylinders and producing 550 PS of
peak power.
With respect to engine options, the Indonesian - spec Honda Brio, much like India,
draws power from the 1.2 - litre VTEC four - cylinder petrol engine tuned for 88 bhp and 109 Nm of
peak torque paired to a 5 - speed manual and automatic transmission.
Since this is an AMG - tuned model, it
draws power from a 3.0 - litre V6 petrol mill producing 367bhp and 520Nm of
peak torque.
Peak load electricity — the
power that consumers
draw on in the middle of a hot summer afternoon, for instance — costs a lot more than a region's average cost of electricity.
One is «dispatchable load,» i.e.,
power consumption that can be scheduled,
drawing more energy in times of
peak production and in some cases releasing clean
power back to the grid during the valleys.
Plus, the
power draw at that
peak load is much higher and the amount of time spent in that mode is much greater than on a standard PC.»
We can ball park it, we can decide if a particular device is too
power hungry for our needs (or will have a
peak draw too high for the circuit it shares with other devices) but we can't reliably calculate the real world cost.
such
power draw — while 20V / 5A is a
peak for USB PD, actual chargers see a much lower specification with our tested Pixel clocking in at up to 15W (5V / 3A), and the Pixel XL up to 18W.
Over the course of the last week, there's been speculation that Apple is throttling the performance of older iPhones with degraded batteries, leading to resurgence of accusations that Apple is deliberately slowing down older iPhones that aren't operating at
peak battery performance.In a statement to TechCrunch on the results people are seeing when testing iPhones with older batteries, Apple says it is aiming to smooth out the high
power draw peaks that can result in shutdowns and other problems in older devices to «deliver the best experience for customers.
While Apple does not refute what was found, it says that the reason for the
power management and CPU throttling results identified by Poole and other Geekbench users is simply a case of it trying to smooth out high
peaks of
power draw in an attempt to prevent iPhones with older batteries from shutting down unexpectedly.
Because those older batteries are incapable of handling
peak current
draws with the same effectiveness of iPhones with newer batteries and more efficient processors, they run the risk of the device
powering down to prevent damage to its internal components.
The reasoning behind this from Apple is to prevent «high
power draw peaks» which can lead to shutdowns and other issues on iPhones with older batteries.
It turns out that Apple is limiting how much
power an iPhone processor can
draw in certain circumstances, therefore limiting the processor's
peak performance.
