======= Summary =======

The ZeroLemon 5,200 mah battery case is great. It offers great battery runtime, Fast Charging, and a smooth-feeling case that also provides additional grip compared to the slippery glass setup of the Galaxy S9+. However, this type of battery case is not for everyone and some people will shun it because of its heftiness and bulkiness. But for people like myself who appreciates this type of battery case - and is willing to find room in one's apparel or bag - this battery case can be a very convenient alternative to carrying around a portable power bank. It is especially useful for when one is on a vacation or a trip that involves more frequent GPS, camera, and multimedia usage.

======= Design =======

The case has perfect fitment and all the buttons, microphones, speaker, and the charging port align correctly. The case is made of soft TPU material that is smooth with some added grip. Compared to past ZeroLemon cases I've used before (Galaxy S4, Galaxy S6 Edge, Galaxy S7 Edge), this one is the best one yet. Prior cases felt cheap and the rubber or TPU material felt "less dense." The GS9+ case has a higher-quality feel and a more "dense" feel, for a lack of a better word. In other words, I like it this time and holding the case for long periods of time doesn't make me feel bad that I placed a really expensive phone inside a really cheap and crappy case.

Installation of the phone into the battery case is a simple and easy affair. I start by angling the phone a bit and inserting the phone starting with the bottom half of the phone. Once the USB Type C port on the phone clicks into the case, I push and pop in the top part of the phone. When removing the phone, I reverse the process and take out the top part of the phone first.

I really like how easy it is to press the hardware buttons. Due to the sides of the case being properly rigid but also thin, the buttons are easily activated with no extra force.

I also REALLY appreciate the fact that this case is fully-compatible with my full-adhesive TGSP (EyeO2). My two previous ZeroLemon cases (GS6E, GS7E) prevented me from using a TGSP by causing the glass protector to pop off.

Besides the extra thickness and weight introduced by using a battery case - which everyone (hopefully) expects before spending money on one - there is one additional minor annoyance. The fingerprint sensor (FPS) is harder to get to because it is now deeply recessed inside the camera cutout area. It is not super hard to reach but it does take some time to get used to. Fortunately, the FPS sensor on the GS9+ is much faster to activate than it was on the GS8+ and is more tolerant to different fingertip placements. As a result, I was still able to unlock my phone 100% of the time but it just took a little longer to unlock the phone because it took more time for me to make my finger travel to the FPS.

Another aspect that became slightly more difficut was using the phone one-handed. Although I don't have big hands, I do have long fingers. With just a slim case on the GS9+, I can do everything with just one-hand. With the ZeroLemon battery case on, I can still do things one-handed but it became more difficult and strenous.

To sum it up, I find the design of the GS9+ ZeroLemon battery case to be their best one yet.

======= Performance =======

The performance of the battery case lived up to my expectations and their marketing claims. The case offers Fast Charging and my phone took advantage of it often and charged up my phone very quickly (see my picture). Turning On and Off the battery case is dead simple and easy to use as well. Hold down the button on the back of the case for a few seconds to Activate and hold down the button for a few seconds to Deactivate.

The battery case itself gets charged through its USB Type C port and I experienced no charging issues. I charge all my electronic gear at bedtime and leave them plugged in overnight. I don't know how long it takes to fully charge the battery case from empty but it is fully charged and ready to go when I wake up in the morning.

I've never had any performance or quality issues with past ZeroLemon battery cases and this one for the GS9+ is no exception. If my past experiences are any indication for the future, this case will become a reliable and dependable companion for those times when I really need the extra juice & stamina (long social outings, vacations, trips, etc).

======= So, is it good? =======

Absolutely. ZeroLemon has been in business for a long time now and is one of the market leaders when it comes to battery cases. Although I've never had to use their warranty before, I know they have a good reputation for customer care and support. Their customer support via email is certainly timely and friendly. This GS9+ battery case improves upon their previous designs, fixes prior shortcomings, and performs excellently. It is an excellent substitution and/or addition to a portable power bank and I highly recommend it.
