In the test: Magnetic battery case from hardwrk for wireless charging of the iPhone XS

Even with the hardwrk battery case, the iPhone is comfortable to hold - but you should hold it the right way round so that you can see the display. ;-)

Today I have a little specialty in the Sir Apfelot test studio: a magnetic battery case for the iPhone XS that charges the iPhone via Qi charging. why this Magnetic battery case is magnetic and how fast it can charge the iPhone, you can find out here in my experience report.

The battery cover was kindly given to me by hardwrk made available. However, this did not affect my test report and the company did not receive the article for approval before it was published, but has to live with what I write.

Technical data of the battery cover

  • Available for iPhone models X, XS, XS Max and XR
  • Capacity: 5.000 mAh or 5.500 mAh for the iPhone XS Max
  • Weight: 200 grams or 215 grams for the iPhone XS Max
  • Battery: lithium polymer
  • Charging connection on the case: Lightning socket
  • Power via Qi charging: 5 watts
  • Power when charging the case via Lightning: 7,5 watts
For a battery case, the hardwrk case looks amazingly good. Much better than the counterpart from Apple, which comes with a quasimodo hump and costs many times more than this battery case.

Design and processing of the case

There is little to complain about about the design. Both the case, in which you put the iPhone, and the battery part, which is magnetically attached to the case, are very neatly processed. Inside the case there is a kind of velvet that protects the iPhone from scratches. Some thin magnets are integrated in the case, which couple with those in the battery part and thus ensure automatic "centering". The case always fits perfectly on the battery pack and does not stick out to the side.

Contrary to what hardwrk said, I would say that magnets are also built into the case. This can be an advantage if you already have a magnetic holder in the car.

The back of the battery pack has a piano lacquer finish in the upper third, which looks very classy, ​​but unfortunately also magically attracts fingerprints. But since I assume that such accessories will get a few quirks sooner or later, I don't really care about the fingerprints.

The two surfaces of the hardwrk battery case, which are magnetically coupled, are also coated with a soft, velvety material (I've read microfiber) so that they can be moved against each other without scratching in order to close the iPhone and the battery pack separate.

The adhesion of the magnets is so strong, by the way, that you cannot separate the two parts of the battery case from each other, even by shaking it vigorously.

The LED segment display provides information about the battery status of the case while charging.

Technical details of the hardwrk battery cover

How the battery cover works technically is also well resolved. The case recognizes itself when it is connected to the iPhone and immediately starts charging. During the charging process, the LED segment display on the battery pack lights up permanently and discreetly shows the current charge level in percent.

This display can also be triggered by a small button on the top of the battery cover when you are not charging, but want to know what percentage of the battery still has to offer.

The Lightning connector is located in the middle on the top and the button is offset a little to the edge, with which you can query the battery level or stop and restart the charging process (photos: Sir Apfelot).

A few measurements from practice

Of course, I also wanted to measure a bit to see how quickly the case charges my iPhone XS. I measured this with the tool "CoconutBattery"and the iPhone timer. The battery case charged my iPhone XS from 20% to 66% (+ 73%) in 7 minutes. That doesn't sound like much and makes me doubt the 2,5 hours that an Amazon reviewer took supposedly made it, but Qi-Charging is never the fastest way to get your iPhone a little bit of power. According to CoconutBattery, the iPhone was charged at 3,6 watts, which in itself is not a bad value.

As a test, I compared it again with "normal charging" via the USB-A port. I went from 20% to 73% (+ 86%) in 13 minutes and the iPhone was charged with about 5,2 watts.

On the left you can see the CococnutBattery screenshot when charging with the Magnetic Battery Case and on the right when charging with a standard USB charger (without USB-PD). The difference is not very big.

Since I was also interested in how far and quickly you can charge the iPhone from a very low percentage range, I once put it in the completely full battery case with a 15% charge. I was curious whether the battery case would be empty or the iPhone XS would be full. The result:

The iPhone is 5% full after 02:100 hours and the battery case still has 19% charge. Five hours of charging sounds like a lot, but to be fair I have to say that I was at 3% after just 90 hours. The last 10% always take a long time to load, but that's normal.

By the way, the Lightning connector, via which the battery case is charged, is built into the top. I first considered whether there were any disadvantages to this, but basically it doesn't matter, since you only charge the case at home and it is then probably not connected to the iPhone. But I still wanted to mention it.

Areas of application and advantages

I have to admit, I've always wondered what the use case for battery cases in general is. I have always been on long hikes with power banks and charging cables and have ridden quite well with them because I could always charge the iPhone in my jacket pocket.

But if you want to go out in the summer and don't want to take a backpack with you, then a battery case like this is the better choice, because you can still put it in your pocket while you have a rather unwieldy "thing" with you with a power bank with a connected charging cable .

Even power banks with Qi charging do not offer any advantages here, as the iPhone is not magnetically fixed there. That means, even with the smallest movements, it slips off the power bank and the charging is interrupted.

A second advantage that the hardwrk battery case offers is that the iPhone's Lightning connector remains free while it is charging. So you can continue to enjoy music through wired headphones while the iPhone is charging in your pocket.

No question about it: every battery case makes the iPhone much thicker. But thanks to the rounded edges, this case can still be stowed away easily in the trouser pocket.

Frequently asked questions on Amazon

In Amazon, some potential customers asked questions that I would like to answer here:

  • Do the magnets in the case interfere with the autofocus of the iPhone camera?
    No, the magnets are approx. 2 cm away from the camera and have no influence on it. If that were the case, you would notice it first with the optical image stabilization, because this is also solved with magnetism and is certainly more sensitive than the autofocus. But I didn't notice anything.
  • Does the iPhone with the battery case still fit in your pocket?
    Yes, with me the complete "package" consisting of the battery case and the iPhone still fits in my back pocket. Of course, that depends on the pants. I can imagine that due to the thickness of about 2 cm it becomes tight for some bags.
  • Is the shell thick enough to withstand a fall?
    The part of the case that the iPhone goes in is definitely thick enough to protect the iPhone in the event of a fall. I would estimate that the battery part doesn't break quickly either, but the shiny plastic on the battery case is sure to be visually damaged.
  • What material is the case made of that will stay on the iPhone?
    The cover is made of a solid plastic core and covered with silky smooth silicone, and it is padded inside with microfiber.
  • Is the case itself magnetic?
    According to hardwrk, the magnets are only in the battery part, but I think there are batteries in both parts, otherwise I can't explain how my paper clip got stuck on the case in the test. ;-)
  • Can you use the Lightning connector for headphones with the case attached?
    That's fine. This is also one of the elementary advantages that this case has compared to a power bank.
  • Can you charge the battery case yourself using Qi charging?
    No, this is not possible. The case itself is charged via a Lightning connector.
  • Do I have to activate the case for the iPhone to start charging?
    No, the case recognizes when the iPhone is within the charging range and automatically starts the charging process. This even works without the thin iPhone case. You can place the iPhone directly on the battery part and Qi charging starts.
  • Does the iPhone charge permanently when connected to the battery case?
    In principle yes, but you can stop and restart the charging process at any time with a small switch on the upper part of the battery cover.
  • Can I still charge the iPhone in the case with other Qi charging stations?
    Yes this is not a problem. The case also doesn't interfere with other chargers that work with Qi charging.
  • Does the case charge the iPhone with 5W or 7,5W?
    The case works with 5W.
  • Is the case for the iPhone included?
    Yes, this is also important because the battery pack does not hold onto other cases.
  • Does the case also work with the iPhone X?
    Yes, it is compatible. The iPhone X has almost the same dimensions and also has Qi charging, so that it can be used for the iPhone X without any problems.
Even with the hardwrk battery case, the iPhone is comfortable to hold - but you should hold it the right way round so that you can see the display. ;-)

My conclusion

I have now used the Magnetic Battery Case from hardwrk a few times and can recommend it to anyone who is basically thinking of buying a battery case. It's definitely prettier and cheaper than the Appe battery case.

Personally, I've been using it for many years my beloved Quadlock case with the appropriate fastening setsso that no other shell comes into consideration for me. In addition, I've hardly had a day since the iPhone XS that I didn't go to sleep with at least 40 to 50% battery. That means: an empty iPhone is absolutely no everyday problem for me. On the rare days when I use the GPS for a long time, there is usually a power bank in my backpack so that I can charge it in between. A battery case therefore solves a problem that I don't have.

But if you often have to struggle with an empty battery and you are less determined when it comes to the case, then you should take a look at the hardwrk battery case.
