Samsung Chips Will Get Faster and Easier on Your Battery in 2020 (cnet.com)
Processor progress is harder to come by these days, but Samsung says it'll build chips next year that will give you a bit more battery life or a little more speed. From a report: Through improvements charted by Moore's Law, chip electronic components called transistors get steadily smaller. On Monday, Samsung said it's taken the next step along the Moore's Law path, shrinking a transistor measurement to 5 billionths of a meter -- 5nm -- from 7nm. To get some idea of just how teensy that is, about 2,000 would fit end to end across the width of a human hair. The new petite size means the Korean company will be able to add more electronic abilities to its chips. It also means the chips will get either a 10% speed boost or a 20% savings in power. The development could help not only Samsung, which builds the Exynos processor for its own phones, but also Qualcomm and other companies that rely on Samsung's foundry business to build their chips.
The problem isn't the CPU. The problem is all the Apps that insist on running constantly in the background, using GPS and other tracking sensors to spy on you.
I have a Moto G4 and I couldn't figure out why the battery was only lasting 6-8 hours. One day I finally quit Facebook and uninstalled the Apps for Facebook and Messenger, and voila! Now I get 24+ hours of battery life easily.
Get app developers under control and you get battery usage under control.
