    By adding this case I get days of extra battery use. The case was easy to install. It does add more weight to the phone but I do not mind. It works well and I am happy with the purchase

    I absolutely love this battery case. It shows under your device battery lists. It also can be used with wireless chargers or lighting. I ALWAYS have a charge and never have to worry about not being dead. So far the white has stayed. I clean it with rubbing alcohol water mix I use for glass. NO issues so far and the case has stayed intact after being dropped screen first onto a hard tile floor. Didn't break the screen!!! :) Buy this. You won't regret it. I bought mine open box too, highly encourage this with a little savings.

    Great Option for Travelers

    I charged both my phone and the case (separately) the night before and put the case on my phone at 8am. By 8pm, the case was depleted but the phone still had 100%. I used twitter, instagram, facebook, apple music, Skype, email, text and played candy crush on the device. This is a great option for those who travel often and don't want to carry an extra power bank. It makes the phone extremely heavy tho. I detest bulky so that is the only con for me. I understand its a case with a battery so I won't take off a star for that as bulkiness/heaviness should be expected. I will likely only use when I'm traveling for more than 5 hours.

    Extends battery textured grip a little too bulky.

    The case is ideal for extending your battery especially if you can’t get to a plugin too charge your phone. The texture of the case helps to keep it from slipping from your hand but the added bulk can make it harder to handle one handed and more difficult to get in and out of your pocket. Like most Apple accessories the price tag is pretty high. If you use it everyday it will gradually lose its power and probably be much less effective within a year.

    The Best iPhone Battery

    So I just love this battery. It’s an Apple made accessory and it shows. First it shows up on your battery gauge on the Power Widget, second its Apple CarPlay thruput, that’s means you can use the port with Apple CarPlay no issues. Third it lets you surface charge both it and the iPhone on your charging pad. The battery gives me a super life on long school days in courtrooms or doing intense legal research online. A must for heavy iPhone users

    Great case for extra battery

    This is a great case option for adding extra battery life. It never fails you buy a new phone and the battery is great for 4-5 months then it does not last even a day. With this case I can go through a full day of heavy use and still have battery left. The only thing I don’t care for is that my magnetic car mount does not work inside the case and you would think Apple would integrate something in the case. Wireless charging does still work on this case though which is a nice feature.

    Bought this smart battery case for my wife when she was going to travel overseas. She dislikes carrying extra stuff during the day like a battery bank and charge cord. This was easy to convince her to use. Plus she loves pink. Would easily last her the whole day without having to conserve battery. Plus it works automatically, no need to push any buttons. A bit pricey but very convenient.

    Yes, it adds weight and a bit of bulk but this smart battery case is fantastic. As much as I use my phone I have no issues making it through an entire day.

    I bought this because I was running out juice halfway through my work day, keep in my I’m playing music through my Bluetooth Beats headphones and Social media-ing, so I understand the demand from my device was a lot. This charging case is doing its job very well, now I don’t have to charge until I go to bed. It is bulky, and heavy but I’ll trade that for the amount of battery life it provides me.

    I love this case and the extended battery. My phone can now get through the entire day with heavy use and not entirely drain the charge. I also like the soft silicone case that's just enough to enhance the grip in your hand but not interfere with sliding into and out of your pockets. It's very durable too and survived many drops while preventing my phone from being damaged. I destroyed my first case after 2 years, and like this one so much I repurchased it.

    I bought this case, although I’m not too heavy a user, some days I am using my phone non stop (playing games) and using the internet. My battery gets low around midday. I came across this case and decided to give it a go. It was on sale and I have used this case for about 2 weeks and I love it. I have no worries about my battery draining before my day is done. This case does the trick. The one thing I don’t like about this case is it’s on the hefty side. But it is a battery so I won’t complain too much.

    Great integration but pricey for what it is

    The iOS integration is great (being able to view the case battery status in the battery widget, etc.). The case is easy to hold and less bulky than other battery cases. It does show hand oils constantly. Capacity could be higher, it doesn’t feel like it quite doubles the XS max battery life potential. It is also easily damaged, and I took a small chunk out of the rubber at the perimeter of the screen inexplicably.

    Excellent to get more than one day battery life

    I use this case to keep my phone charged throughout the day. I always have so many important texts, emails, and phone calls that I need it to last longer than normal. It’s great for anyone who uses their phone constantly but needs extra battery and decently solid protection. I got it on sale but the normal price is a little high. But you get built in Apple features that are important to me such as wireless charging and keeping one lightning cord.

    The case is nice, but add weight to the phone. Uncomfortable to manage with one hand. It works great but takes time to charge with wireless charger. Also, battery drains fast. By noon I have 50% on light usage. Overall I am getting a little over 2 days of light usage. Keep in mind that I am not a facebook user and I know that app drains the battery even faster. But for $100 not bad

    I've been using this case for a month now and I love it. Fits like a glove on my SX MAX a bit heavier but you get used to it, a nice grip on the hand. Built like a tank has taken a couple drops from my 3 yr old and nothing. Battery is great I am a heavy user battery will last me about two days no problem. Phone stays nice and cool, speakers sound the same no sound loss!! Would recommend to anyone looking for extra power everyday use it just on trips with no power connection..

    iPhone XS Max Smart Battery Case

    I like the smart charge feature. The design and feel doesn't make the phone seem that much more bulky, although there is an obvious difference in weight. Still, not much of an issue. Phone is pretty protected, even from drops. Just be aware, due to the added weight of the battery and silicone shell, damage to edges/corners could occur much easier when/if dropped.

    This case does what it is supposed to, it gives your phone a extra charge of about 50-60% I would say. It tends to run rather hot when it’s connected to your phone and it’s on the charger. The case is also rather large and very difficult to remove once it’s on the phone. But the case performs rather well and helps to protect it from drops as well.

    Nice case with battery to keep going longer

    This is a great case. It is obviously heavier with the battery so it’s a trade off between the weight and how long you need to go without plugging in to charge. It works with a wireless charger as well. You will essentially see two batteries on the phone. One from the phone and from the case and their respective charge. The retail price is expensive, so if you can get it on sale, go for it.

    I like how easy it is to use. Have to charge it out of the box for first time use but it has to be plugged in into the wall outlet and doesn’t charge with the car charger which is a bit inconvenient. It’s also on the pricey side but I get a good 8-9hrs extra which is nice. So far so good going on the first week.
