Powerful Battery

  • The SMRT iPhone X battery case provides a powerful battery capacity of 3600 mAh, and a nominal capacity of 2448 mAh, battery to recharge your iPhone X more than one full charge. Beautifully crafted and over-engineered to deliver to quality you expect from TechSMRT.
  • After spending upwards of $1000 you’re going to need a case that will protect your phone from the inevitable drops and spills. And with only 2700 mAh of battery capacity built-in to your new iPhone X, your going to need an extra battery to get you through the long days of staring at that gorgeous screen.
  • 2700 mAh is technically more power than you will get from an iPhone 8 Plus but don’t be fooled by capacity alone. The X burns power at a faster rate and will not last as long as an iPhone 8 Plus in real world conditions. 

Shock Absorbing Frame

The shock-absorbing frame protects your iPhone X from impacts even at the corners where your screen is most vulnerable.

Lightweight, Comfortable Design

iPhones straight from the box are notoriously slippery. The design of our new X case adds a bit of helpful size and weight. Thin and light sounds great, but IRL, it’s actually easier (and safer) to hold on to a phone with a little bit more heft.

Easy Slide Tech

Our innovative “Easy Slide” technology makes it easy and save to remove and reinstall your case. The phone must slide straight up and down which prevents damage to the lightning port on the phone and inside the case.

Advanced SYNC & Hassle-Free Charging

Sync data to your Macbook, PC or laptop and charge your phone at same time without removing the case. Our advanced chipset charges quickly and safely, and turns itself off quietly when your phone is fully charged.

Built-in Magnet

With the built-in magnet, this case works flawlessly with magnetic car mounts (Car Mount Not Included).

Customer Questions and Answers

  • How long will the battery last?

    • TechSMRT Battery charging cases are designed to offer about one full charge. For example, the new The iPhone X battery case provides a 3600 mAh battery to recharge your iPhone X just over one full charge. This performance, of course, depends on a few other factors including background processes and whether you are actively using your phone while it’s being recharged. And, don’t forget, different phones burn battery at different rates, for instance, the X burns power at a faster rate and will not last as long as an iPhone 8 Plus in real world conditions. Tom’s Guide did some testing to prove it.

  • How well does the case fit my phone?

    • SMRT iPhone battery cases fit your phone perfectly. No blockage of the camera port and easy access to all ports and buttons.

  • Will a phone case protect the resale value of my phone?

    • Yes, keeping your phone in excellent condition goes a long way towards maintaining high resale and trade-in value. You should keep your phone in a case at all times – and always add a real glass (not plastic screen protector). As iPhones and Samsung Galaxy phones get more expensive, the resale and trade-in value has been going up as well. For $25 now, you could add several hundred dollars to the value of your phone when it’s time to upgrade.

  • Can I still use Qi wireless charging?

    • For iPhone 8, 8P, and X, Xs products. No. All battery charging cases interfere with Qi wireless charging. If you want to wirelessly charge your phone, remove the battery case and center the Qi receiver in the middle of your charging pad.

  • Does the case protect my camera?

    • Yes, the phone camera is recessed behind the camera cutout. Although the camera is not covered, because that would result in potato quality photos, the camera should be safe from typical drops.

      For iPhone traditional 6, 7, 8 battery cases and SMRT Metal, Audio Jack cases. SMRT cases do not come with a steel plate built in. We are looking to add that feature in the future. In the meantime, we know of many customers that have added a steel plate inside their SMRT case with great results. Here is a 4-pack of metal plates designed exactly for this purpose.

      The iPhone X and Flex series for iPhone 6, 7, and 8 Plus models have a built in steel plate for magnetic car and wall mounts. These cases work perfectly with magnetic mounts, right out of the box.

  • Will I need a dongle for my headphones?

    • No, SMRT battery cases come with a properly sized cutout for the headphone port (on iPhone 6 models) and lightning port on all iPhone models. You will NOT need a dongle for your headphones.
