[Samsung Galaxy S8+ Accessories] Kawaisa:
The review is for the 6300mAh ZeroLemon battery case for the Samsung S8 Plus.

If you’ve used an extended battery case then you won’t be surprised by the size. It adds noticeable weight and thickness to the phone and it may not be a good fit if you’re into skinny jeans. More importantly, it adds a huge boost of charge to the S8+ which is the real reason for getting a battery case like this.

Total weight with the phone, tempered glass screen protector, extended battery, and TPU case comes out to approximately 14.3 ounces. It is something I would use on an occasional basis when I need more juice from my phone. As the S8 Plus is already quite tall, the battery case adds even more height to it. I haven’t had any worries about it falling out.

Product Packaging

Packaging is quite simple, it’s a white ziplock bag and a brown cardboard box. You get the battery attachment, the TPU outer case, an aux adapter, and a few cards/pamphlets. There isn’t much in terms of instructions, just a small flip out pamphlet that instructs you on how to plug in the battery and case.

The battery attaches to the S8 Plus via the USB-C port on the phone. The battery attachment also charges through a USB-C female port, so there is no need to change chargers or cables that you are already using with the phone.

Props to ZeroLemon includes an aux adapter/dongle as many L-shaped earphone connectors would otherwise be incompatible with the battery case given that the aux jack is really recessed into the bottom of the battery case.

Battery Usage

I charged the case for approximately 12 hours before initial use – as instructed on the white ziplock bag that it all comes in. With a bit on Youtube viewing, web browsing, calls, and gaming, I managed to get 3 days’ worth of usage before I hit the 5% mark in which I plugged it back in for a full recharge. The extended battery gave me approximately 1.3 full charges give or take. There is a power button on the battery case so you can choose when to start or stop the recharging process. The instructions say to perform 5-6 full deplete/recharges in order to maximize battery performance. I will see if it gets any better after seasoning it for 5-6 recharges.

The battery/case

One issue I came across was the fact that the fingerprint sensor is partially obstructed given that the opening for the camera and fingerprint sensor is substantially recessed. I am still able to use the fingerprint sensor because I have short nails, but I imagine this would be an issue for anyone with longer nails. It worked much better with my right index finger opposed to my left.

It’s a simple TPU outer case that snaps on. It has a matte texture that feels good in the hands and prevents slippage.

After testing the battery case with the camera flash, I found no issues.

One of my favorite aspects of this battery case is the fact that the speaker opening is redirected from the bottom of the phone and is forward-facing – the sound even sounds a little bit amplified.

There is no need to remove the phone from the attachment in order to transfer files to your computer – something that is not possible with another extended battery case I tried using prior to this one.

Charging

There are bright white LEDs on the back of the battery case which stay lit while charging. You can also press on the power button on the battery case to check the amount of juice that is left.

The battery itself does not support fast charging from the battery to the S8+, but it does allow for pass through quick charging of your phone if you connect the battery case to your Samsung fast charger.

Takes over 2 hours to charge your phone's battery using the extended battery. Takes about 5 hours to charge everything together.

Overall, I would definitely recommend the ZeroLemon battery case for times when you just need your S8+ to go that extra mile without a charge. You know what you're getting with a large extended battery and it delivers in that aspect.
