'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form.
Over the past few weeks, I've received a lot of questions from readers complaining that their iPhone's display is dimming to the point of almost being unreadable. Several of the readers were using their iPhones for in-car navigation, some were recording video, another was flying their drone using an iPhone connected to the controller, and some weren't really doing anything in particular.
This is quite a common problem, and one that's been plaguing drone operators for a long time. The screen on the iPhone will dim quite dramatically, to the point of making it almost impossible to read. And to make matters worse, you can't turn the brightness up.
On top of that, there will be a lag and the iPhone will appear to struggle to work as normal.
So, what's going on here?
Well, there's a common theme here -- it's summer and the iPhone is getting hot.
