The latest iPhone drop a few weeks back caused the usual media fanfare, with huge publicity for Apple and, commensurately, extreme scrutiny on the product that they released.
While the big palaver has been about the face recognition on the new iPhone X - and to a lesser extent, its inability to work on demand when facing the world's media - there has been a separate storm brewing about another of their new products.
The iOS 11 update that was rolled out last week has been updated onto millions and millions of handsets with users the world over suffering from the inevitable teething problems that come with every upgrade.
For every new feature - and there are plenty - with the new Control Center, increased Wi-Fi and Bluetooth connectivity, a new keyboard layout, a screenshot editor...we could go on - there is the potential for new drawbacks and one of them is a major one: the battery life.
Mobile security specialist Wandera is usually fairly quick off the mark in going through any new software updates and it noticed that, when testing the new features of the iOS 11, the battery life of the device in question plummetted.
"We looked at a subset of 50,000 moderate to heavy iPhone and iPad users in our network running iOS 10 and iOS 11 to compare the average battery decay rate over the past three days," the group said in a blog post.
"Assuming the same device started with the battery at 100%, this chart shows how long it takes to get to 0% for each version. The current estimate is 240 mins for iOS 10 and 96 mins for iOS 11.
"In other words, the decay rate for iOS 10 is 0.006958 percent per second and for iOS 11 it's 0.01739 percent per second," it concluded.
We're not sure what the numbers mean, but it doesn't look good. Given that the update was meant to have a majorly positive effect on battery life, this appears to be the complete opposite.
Wandera put this down to an indexing issue - and the predilection of new users to use all new features at once - and suggest that, if you're running out of juice, that it is possible to limit the apps that are using battery life silently.
If the worst comes to the worst, Wandera suggests that 'low power mode may be your best option until Apple pushes out new updates that will hopefully address excessive battery drain', so just sit tight and hope that Apple have it covered.
