By Gary Sims April 22, 2013 96 48 207 57 There are several 1080p full HD smartphones vying for the top spot in the increasingly crowded high end Android handset market. Among them are the HTC One and the Samsung Galaxy S4. But how do they compare? Here is a “by the numbers” look at these two flagship phones.Advertisement 1.6 mm How much narrower the HTC One is compare to the Samsung Galaxy S4. The HTC One is 68.2 mm wide while the S4 is a fraction wider at 69.8. This difference is minimal and is unlikely to be a deciding factor for trying to choose between the two! 0.8 mm The difference in length. Although the HTC One is slightly narrower, the S4 is a hair width’s shorter. However, like the width, this is unlikely to be a deciding factor for purchasers. 1.4 mm Is how much the S4 is thinner than the HTC One. With large 1080p screens the width and length of the devices are almost predetermined with only the bezel width left to tweak. However the thickness of the device is something that manufacturers can work with and the S4 is thinner than the HTC One. The Samsung is just under 8 mm thin, quite an achievement, while the HTC One is no brick, but does add an additional 1.4 mm making it 9.3 mm thin. 6.35% The HTC One has a pixel density 6.35% greater than that of the S4. The HTC One has a 4.7-inch 1080p display with a pixel density of 469 ppi, while the S4 uses a 5-inch 1080p display. That gives the Samsung a slightly lower pixel density. A key factor for potential owners is the difference in the screen size. Does the extra 0.3 inch make the Samsung a better phone? 130 g The total weight of the Samsung Galaxy S4. The HTC One is just a few grams heavier at 143 g. A noticeable difference? According to Android Authority’s Kristofer Wouk, “At 143 grams, it’s not the lightest phone we’ve seen, but the solid feel on such a thin device is worth the trade off.” 13.04% More battery for the Galaxy S4. Samsung’s flagship uses a 2600 mAh removable battery. The S3 had a 2100 mAh battery and the HTC One is sandwiched between the two at 2300 mAh. Battery life is certainly going to be important. Our tests have shown that the S4 provides a more than adequate battery life, plus it has the advantage that the battery can be removed, something that can’t be done with the HTC One. Zero The number of SD card slots in the HTC One. The amount of internal storage is often a crucial factor for those buying a smartphone, but the ability to add more is, to some, an even more important element. The S4 has an SD card slot which allows you to add an additional 64GB of storage. Although you might not need this extra space at the beginning having the option to add more later could be useful. 200 minutes The time it takes to cut and process the HTC One’s aluminum unibody frame. The Galaxy S4 still uses plastic at a time when others, like HTC, have moved to more luxurious materials for their flagship offerings. Some consumers will reject the S4 because of its plastic build and could prefer the HTC One because it looks more high quality. 10 million Is the number of S4 units that Samsung plans to ship in the first month after the device’s international release. By the end of June Samsung plans to have shipped 30 million devices and is estimating that the S4 will become its most popular phone. In comparison HTC is thought to have shipped 300,000 HTC One units in March and will make a further 1.2 million units in April. By May the company hopes to send out an additional 2 million units. If the phones sell as expected it looks like Samsung will outsell the HTC One by a factor of at least 5! ??? What number is key for you in deciding which Android smartphone you will get next?
