Geekbench developer links iPhone performance issues to battery age and iOS updates<div class="feat-image">
</div><p>[<strong>Update</strong>: Developer Guilherme Rambo has
discovered the software system, powerd (short for power daemon), that Apple put in place in iOS 10.2.1. powerd controls CPU/GPU speed and power. It also
responds to thermal pressure and helps iPhones from catching fire.</p>
<p>Since
powerd was
first released in 10.2.1, this looks to be separate from the Low Power Mode feature and directly related to the performance and battery age issues.]</p>
<p>Last week we reported on the news that a
new battery could solve performance issues with older iPhone models like the 6s. Today, Geekbench founder, John Poole,
published an article describing his findings after diving deeper into the relationship between iPhone performance and battery age.</p>
