Galaxy S3 vs. iPhone 5: Battery life and screen

It might not be a match that some people think is fair, but the two biggest smartphones being compared right now are the Samsung Galaxy S3 vs. iPhone 5. Battery life and a screen comparison are two areas that interest people the most, and these specs have been covered in a couple of detailed reviews.

When it comes to a fair fight some people claim the Samsung Galaxy S3 is aging now and shouldn’t be compared to the iPhone 5, and these users state that the future Galaxy S4 would be a fairer comparison, although some Galaxy S3 owners feel the battery life and screen are far better than the iPhone 5 even though this device has just launched.

Samsung Galaxy S3 vs. iPhone 5 battery life — one of the most detailed battery tests for the Galaxy S3 can be seen in this article, which takes an in-depth look at the 2100mAh battery and connectivity. They found that the Galaxy S3 lasts around 8 hours under heavy usage, although they note a recent software update helped to increase the battery life event further. You can see an overview of their Samsung Galaxy S3 battery life test in the first video below this article.

If you want to compare the above review to that of the iPhone 5 battery life then you should see a detailed test via our earlier article, which highlighted how the heavy usage on the iPhone 5 still delivered more than 11 hours of battery life. This included a video loop as well as many other tasks like accessing social accounts constantly through the day, and leaving LTE and Wi-Fi on throughout the test. Just turning LTE and Wi-Fi off would increase the iPhone 5 battery life by some amount. The reviewer mentioned that the Droid RAZR Maxx only managed 10 minutes more juice under the same test, so anyone that knows how good this Motorola phone is for battery life are sure to understand the iPhone 5 is pretty impressive when it comes to getting you through the day without needing a recharge.

Samsung Galaxy S3 vs. iPhone 5 Retina screen — another review has taken a look at the displays of these two smartphones in detail, which includes tests for viewing angles, colors/intensities, brightness/contrast, screen reflections, and an overview that points out the positives and negatives for the iPhone 4/5 screen vs. the Galaxy S3. You can see the key points from their display review in the tables below, which includes the overall assessments and specs comparison for each screen.

The in-depth review can be seen here and makes it clear that the Samsung Galaxy S3 has the better display when compared to the iPhone 5 screen, although they still point out a few positives for the new iPhone including the fact that it has the brightest display with the lowest values for screen reflectance.

If you own the Samsung Galaxy S3 or iPhone 5 we’d love to know how your battery life is, so feel free to share a comment. It is worth noting that the above review also touched on battery life for the iPhone 5 and Galaxy S3, which found the 6th generation iPhone lasting one hour longer with the display always on at maximum setting.
