As compared to screen protectors, protective films do not provide the same level of resistance against scratches. Along with that, protective films the overall look of iPhone. Hence, most people prefer glass protectors over them. We tested a number of reputed glass protector brands including Body Guardz and Zagg. These are well known brands available commonly but have a high price. When we compared these high cost protectors to the ones Having a lower price, there was not a lot of difference in the level of quality.
We use a standard process to test each screen protector. To start with, we installed each of them on the iPhone X. Our team also went through the instructions offered for installing the protector to check how helpful they were. Once the installation had been completed, we ran our fingers on the sides to see whether any sharp edge was bulging or not. Along with that, we viewed the standard of brightness and color resolution. While we were using the protector, the finger prints were left on the screen. We used a cotton T-Shirt to wipe off and see whether they came off easily or not.
Our team used the Mohs test which is not commonly by most protector manufacturers for checking screen hardness. Instead, the ASTM hardness by pencil test is used but this test is not good enough to test tampered glasses. The reason is that the maximum hardness of a pencil is 9H and it is not enough to test a tampered glass. We used the Moh’s kit that has constituents which can damage a tampered glass. Hence, as compared to the ASTM hardness by pencil test, the Moh’s test was more reliable.
We got a confirmation about the usage of Moh’s test by communicating with Dr Ivar Reimanis who is a reputed professor in the field of ceramic engineering and materials engineering at Colorado schools of mines. According to him, both tests were similarly reliable to check the screen hardness.
For the Moh’s test, we used a number 1 stylus and held it an angle of 70 degrees. After that, we dragged the stylus in different directions with an average force. We repeated this test for different screen protectors and until the glass was scratched. We recorded certain details at the end of each test including the stylus with the maximum number that did not scratch the glass and the total styluses that was unable to scratch it. The hardness ratings of styluses were not available to us so we ranked each protector on the basis of hardness. For instance, if a rating of 6 was given to a glass, it simply showed the resistance that it had.
Our team did not use drop tests because we think that they do not have the desired relevance. In addition to that, drop tests fail to produce the same level of impact on the phone. Hence the results produced by a drop test cannot be considered as the same for all situations.
Based on our tests, the Cellularize iPhone X Screen Protector Tempered Glass was the best. It had a score between and 7 and 8 for the Moh’s test. The same level of durability was not portrayed by any other protector. There are various other benefits that Maxboost puts on the table for its users. To start with, the Maxboost protector is much cheaper than various other expensive brands. Secondly, even the low price package has three protectors. Thus, even if you mess up one of them, you can peel it off and apply the second one. The package contains wet and dry wipes that are used to clean the screen before the protector has been applied.
