With the first iPhone 7s in the bag, the biggest smartphone of all time, and its next-generation iPhone 7 lineup poised to hit shelves, it’s time to ask: Is there any reason you shouldn’t upgrade to the latest flagship smartphone in the world?

According to a new study by the University of Chicago’s Booth School of Business, the answer is yes.

The study found that the iPhone 7 is “probably” the most resilient smartphone of them all, even though its battery life could be a concern.

In fact, the battery life of the iPhone SE, the iPhone 6s, and even the Samsung Galaxy S7 all improved significantly during its life.

The smartphone is rated by Consumer Reports as having a battery life that can last up to 10 hours, which is good for an iPhone SE or S7 edge.

The battery life on the iPhone XS and XS Max is also very good.

In a world of “waterproof” smartphones, the newest iPhone is definitely the best.

However, the study also found that battery life is a function of a smartphone’s internal hardware.

The most important part of the battery is the internal components like the camera, processor, and RAM.

The batteries in smartphones are designed to last for a long time, but they also degrade over time, which makes it harder to upgrade a phone with a battery that’s not as good as the original.

The study found iPhone batteries have an average lifespan of more than 20 years.

In other words, if you’ve got an iPhone 7 or iPhone 7 Max in the box, you’re in for a very long time.

The problem with iPhone batteries is they tend to degrade over a long period of time, meaning the smartphone will have trouble surviving a drop.

The new study found smartphone batteries have average life of 10.6 years, compared to 7.6 for the iPhone.

The iPhone 7 has an average life in the range of 20 years, the most durable smartphone on the market.

But if you’re thinking about upgrading your smartphone and you’re worried about battery life, you may want to reconsider.

AppleInsider reports that the battery in the iPhone 9 is supposed to last a whopping 12 years, but in reality, the average iPhone battery will last around 4 years.

That means upgrading to an iPhone 9 Plus could be just as effective.

In other words: the iPhone will probably last longer than a 12-year-old child.

The iPhone SE battery life comes in at a much higher 10 years, so it’s unlikely to be an issue with this iPhone.

But you can always upgrade if you get an iPhone X, which has a 10-year battery life.
