Reading news, listening to music, checking directions, finding restaurants, playing games, brushing forums, mobile office, shopping and paying for bills ... Today's smartphones can do too many things. Taking iPhone 6 as an example, the powerful processing performance, fine screen, and rich Internet functions all give us an excellent user experience and make modern life more and more convenient.
However, the accompanying side effect is a huge increase in power consumption, and there seems to be no fundamental solution to this problem. As a result, the power of the iPhone 6 is completely insufficient to support one day of use, resulting in a bulky mobile power supply almost becoming a daily necessity. Not only that, the iPhone 6 and the mobile power supply need to be charged separately, and a nasty cable is also dragged when charging the iPhone 6 with the mobile power supply. In this way, the convenience brought by the iPhone 6 is greatly reduced. It should be a life assistant, but users need to invest too much maintenance energy for it. I believe that this embarrassing situation is really helpless.
Fortunately, accessory manufacturers have already taken action, and the rechargeable integrated protective case called "back clip battery" has become a new choice. They can be installed like an ordinary iPhone 6 protective case to achieve integration, which is omitted compared to mobile power. Connecting cables greatly improves convenience. Nowadays, there are many battery packs for iPhone 6, but the prices and styles of these products are very different, and regular products and imitations are mixed. How to choose a battery pack with a quality and ease of use that will surely stump many users. .
In order to solve this problem, this time we collected several representative iPhone 6 back clip batteries on the market, hoping to compare them in as much detail as possible, show their advantages and disadvantages to readers, and buy this for everyone. The back clip battery provides an important reference. There are 5 products in this comparison, they are from mophie, Kuke, MiLi, GoesTime and Gotop.
The picture above from the left is mophie juice pack air (priced at 788 yuan), Cool Shell iPhone 6 charging version of the classic model (priced at 198 yuan), MiLi Power Spring 6 (priced at 299 yuan), fruit era iPhone 6 version ( Price 168 yuan), Gotop GRNF GT-6X2600 (price 499 yuan). Due to the longer complete product names of some of the tested products, the brand will be used as the abbreviation for the respective products in the following text.
The back clip battery can be regarded as a mobile phone case with a built-in battery to increase the charging function. One of the major advantages compared to the mobile power supply is its portability. Therefore, we started from the volume and weight aspects of this, starting this time on 5 back clip batteries Horizontal comparison evaluation.
First of all, let's look at the length comparison of 5 products. Readers who have been in contact with the back clip battery of the iPhone in the past may have an impression that after the installation of such products, the iPhone will grow a very unsightly "chin" without exception. Fortunately, at the end of last year, Cool Shell took the lead in starting the "no chin" trend of the back clip battery, which also indicated a new direction for the development of the iPhone back clip battery. The reason for this is because many brands of products have begun to use various methods to optimize the connection between the back clip battery and the mobile phone, and strive to achieve or as far as possible a chin-free look and feel.
It can be found that in addition to mophie still having a thick chin like an old-fashioned back clip battery, MiLi, Guodai and Gotop have all followed the footsteps of the cool shell, allowing their body shape to be effectively controlled. Among them, MiLi uses an external flexible cable connection method, which is stored in the body when not in use; in the era, it used a detachable small connector, which was transferred to the side of the body to reduce the length when not in use, but because the connector is split, It may fall or be lost during use.
As the pioneer of no chin, Cool Shell can be regarded as the ultimate, fully integrated back clip body, which does not require users to plug or unplug cables or connectors in both charging and non-charging states. Surprisingly, Gotop GRNF also achieved almost the same effect as Cool Shell. In contrast, although the designs of the MiLi and Guo era are still novel, there is still a certain gap compared with the truly integrated products such as Cool Shell and Gotop GRNF. Of course, they are a lot of improvements compared with mophie. .
The length of the back clip battery control determines whether the iPhone 6 is beautiful after installation, and the width and thickness are important indicators that directly affect the grip.
The width is mainly affected by the border. Since there are no complex components on the border, the 5 products will not make the iPhone 6 too wide after installation. Through actual measurement, we found that the width of these back clip batteries is not much different after installation. Among them, mophie will make the iPhone 6 more than 6mm wide after installation, which will still have a certain impact on the grip sensor.
Then there is the thickness comparison. It is impossible to increase the thickness of the back clip battery containing the battery.
mophie thickness is about 15.05mm
Cool shell thickness is about 11.41mm
MiLi thickness is about 15.02mm
The thickness of the Guo era is about 11.41mm (the thickness of the protrusion including the charging connector will reach 13 mm)
Gotop GNRF thickness is about 11.43mm
Through the thickness comparison, we can see that these five back clip batteries can actually be divided into two categories. Mophine and MiLi have large-capacity batteries, and have abandoned light and thin. The other three models, such as the Cool Shell, are obviously the first to control the thickness. They all use thin batteries. After installation, they only increase the iPhone 6 by about 4mm.
From the point of view of the original design of the back clip battery, it may not be desirable to be too heavy due to the large capacity battery. After all, the product of the back clip battery was born to recharge the iPhone with minimal impact on portability. As a case that will be installed on the iPhone for a long time, if the iPhone is made too thick, which affects the comfort of the grip, it may be better to use a mobile power supply. Therefore, in terms of thickness, we believe that the design philosophy of mophie and MiLi deviates from the original intention.
As with the previously measured width and thickness, weight is also an important part that affects the feel of use. We tested the weight of the iPhone 6 itself, after installing 5 types of back clip batteries, respectively.
iPhone 6 installed mophie total weight 226g
The total weight of the iPhone 6 after installing the cool case is 198g
iPhone 6 installed MiLi total weight 236g
The total weight of the iPhone 6 after installing the fruit era is 182g
iPhone 6 installed Gotop GRNF total weight 201g
After measurement, the weight of the iPhone 6 itself is about 128g, and the total weight of the three lightweight back clip batteries, Cool Case, Fruit Times, and Gotop GNRF, is about 200g, and the heavyweight mophie has reached 226g. It even reached 240g, which basically doubled the weight of the iPhone 6. The test data is on the one hand, the actual experience can also clearly feel the greatly increased weight of mophie and MiLi, plus the thickness of the two back clip batteries is also considerable, and it will obviously feel difficult when used with one hand.
mophie
mophie uses a skin-like surface, which is comfortable and smooth to touch, but it is prone to sweat and oil stains, and the fingerprints remain obvious.
Mophie has a serious flaw-the mute lever is too jerky. This is because the width of mophie is larger than that of the ordinary back clip battery, so not only the volume button and power button are extended, but the mute lever also needs to be extended to operate. However, the force of the extension lever is not as direct as the extension button. In addition, the mophie shell module does not use a material with high hardness, which results in a strong sense of drag in the operation of the lever. For frequent meetings, you need to switch to mute frequently. For users with ringtone patterns, the experience is poor.
Cool shell
The back cover of the cool shell also adopts skin-like design, which is comfortable and smooth to touch, and can effectively avoid sweat stains and fingerprint residues. It adopts aluminum-magnesium alloy frame and has excellent texture, but the disadvantage of this high-level sense is that it is heavier than the use of plastic materials. Considering that its overall weight is still lightweight among the tested products, it is not easy.
In terms of physical buttons, the cool shell uses the buttons on the frame for the volume and power buttons, which feels good. For the mute lever, because the thickness of the cool shell frame is well controlled, the mute lever is left blank to avoid the impact of the hand feeling. The cool switch's charging switch button has a good sense of confirmation. The white LED power indicator has improved the grade of the whole machine, and the brightness is moderate. The use feeling is still very comfortable.
MiLi
The overall material of MiLi is ordinary plastic, and the surface is not specially treated. The cable connected to the mobile phone is made of soft rubber, and it is not easy to damage when it is plugged and unplugged many times. This is worthy of recognition.
However, the rubber wrap at the joint is rough, with obvious burrs, and the workmanship is indeed poor. The indicator light on the back shows the low-cost blue LED, but after treatment, it is not too dazzling.
Fruit age
The appearance of the mold line on the surface is very obvious from the appearance of the era. The direct disadvantage is that the overall sense of cheapness is strong, but the touch is acceptable. This product is not difficult to judge from the level of workmanship materials, it should be the result of trying to control the manufacturing cost.
If the times display the remaining power in a more interesting way, touching the bottom 4 contacts with your finger will light the indicator, and the remaining power will be determined by the blinking of the indicator. However, the success rate of lighting is not very ideal, sometimes you need to rub your finger left and right to trigger. In addition, the internal components of the indicator light are estimated to be of low grade, resulting in uneven transmission, making "OCD" somewhat uncomfortable.
Gotop GNRF
Gotop GNRF also uses a skin-like surface, which feels good to touch, but fingerprints are more likely to remain. Overall, its design lacks the necessary embellishments, and it looks like an unfinished product. If you consider its selling price of four or five hundred yuan, it seems a little under-standard.
At the charging switch and indicator light, Gotop GNRF is also an unusual way. If you do not read the instructions, the user may not find where the control keys are. In fact, Gotop GNRF hides the switch and indicator light in the volume key. Use the micro switch and thin LED built in the volume key to trigger by pressing the volume key lightly. Although full of creativity, due to the complexity of the buttons and the inaccurate positioning, the mobile phone sometimes does not feel the confirmation when tapping, and even the switch will fail. Need to repeatedly disassemble and disassemble the mobile phone to achieve accurate positioning. But although the actual effect is not good, this design idea is still impressive.
