With data like that in this news, it is very normal that Apple has worked on systems like the Smart Data Mode. At Tom’s Hardware they have done some first performance tests with the 5G on the iPhone 12, and they have found that both the iPhone 12 like the iPhone 12 Pro consume approximately 20% more battery power when working with 5G.
The Tom’s Hardware test consists of using 4G or 5G networks to continuously browse several web pages, at a rate of one every 30 seconds and with the screen brightness at 150 nits. With the 5G activated, the battery of the iPhone 12 and the iPhone 12 Pro have lasted 8 hours and 25 minutes and 9 hours and 6 minutes.
Two hours less, but pushing the machinery too hard
By comparison, using only 4G, the same test figures come out at 10 hours and 23 minutes and 11 hours and 24 minutes. It’s about two hours difference in useIn the case of 5G, it is clear that 5G technology requires higher consumption. The iPhone 12 Pro Max and the iPhone 12 Mini will still have to perform, but it’s clear that the battery size will make them last longer and shorter.
Anyway, you have to think that we are talking about this two-hour discount by loading a whole web page every half a minute and for hours and hours. That’s a lot of data (I don’t want to see the bill of the test person), and I wouldn’t be surprised if in everyday use that battery reduction exists but is quite minor.
Remember: renewing the iPhone just to have 5G speeds is not the best idea today. Even there is not enough time for this connectivity to be deployed throughout the territoryand its maximum efficiency can only be experienced in a few countries at the moment. But when 5G becomes an everyday item, we will have to get used to the fact that the battery consumption is somewhat higher.
