[Review] Zerolemon 3,500mah Battery Case

I've been using this ZeroLemon battery case on and off for my Galaxy S6 Edge in the past couple of months since May and I have to say that I like it a lot!! I've been a fan of ZeroLemon since 2013 when I began using their products for my Galaxy S4 (3000mah & 7500mah batteries) and this product has lived up to my expectations.

This product consists of 3 main parts - the 3500mah extra battery, a little bridge connector that connects the 3500mah battery to the micro USB port on the bottom of the phone, and a TPU case. Here is a picture of what they look like:

It is very simple and easy to put together the package. You first connect one side of the little bridge connector to your phone and connect the other side of the bridge connector to the battery. You then insert the phone and the battery together into the TPU case.

Once everything has been put together, it looks like this:

Putting on the battery case makes the package as tall as a Galaxy Note 4 and about double the Note 4's thickness.

I expected the phone to become super heavy but I was pleasantly surprised that it wasn't too bad. My old Galaxy S4 with its 7500mah extended battery was heavy. This 3500mah ZL battery case is not bad at all. Despite the tallness and thickness, I am still able to use the phone easily with one hand, which is very important for me. The phone is still comfortable to hold and use.

One thing that struck me was the improvement in the quality of the TPU case ZeroLemon used for this product compared to its older TPU products. The feel is way better as the TPU material is now more solid-feeling with a nice texture to it. The older ZL TPU case material felt spongy and cheap in comparison. Kudos to ZL for improving their TPU case material and quality.

Fitment of the TPU case is very good as well. There are no glaring gaps anywhere and the phone is secured snugly with no nervous looseness or movements.

The main star of this kit, of course, is that extra 3500mah battery and it performs very well. My wife and I went far away from home yesterday to do some outlet shopping and I knew I would probably run out of juice during the trip with all the GPS & data usage. About the middle of the day, my phone battery was down to about 30%. So I activated the ZL 3500mah battery by holding down the Power Button on the back of the case and the phone began charging itself right away. About 1 & 15 mins later, the phone was fully charged back to 100%. Nice~! To turn off the charging function, I pressed down on the Power Button again. Very simple.

There are 4 indicators on the back of the case that lets you know how much charge you have left in the 3500mah battery. After that charging session from 30% to 100%, I had 2 bars left which was what I had expected.

So how do you charge the ZL battery pack? You connect your phone charger cable to the microUSB charging receptacle on the lower-left side of the battery case. I noticed that the ZL 3500mah battery gets charged first, followed by the internal OEM battery. After plugging the charger in at night and looking at the phone in the morning, both the ZL battery & OEM battery were fully charged to 100%.

To sum things up, I'm very happy with this ZeroLemon battery case. It is easy to set up, easy to hold and use, and the important battery extension capability just works as advertised.

++ Pros ++

-3500mah backup battery capacity!!

-Easy setup and comfortable to use.

-Good quality TPU case.

-Battery charges fast for not being a FastCharge type.

-The raised lip of the TPU case allows the phone to be placed face-down.

-The case routes the sound to the front so the phone with the case on becomes front-facing rather than down-facing.

++ Cons ++

-A bit difficult to slide the phone inside the case if you have a screen protector on the phone and don't want it to get wrinkled up. It's possible to not mess up the screen protector but takes some effort.

-At maximum volume level, the audio sounds a bit hollowed out and distorted. If one lowers the volume a couple notches, distortion goes away but still not as clear-sounding as having no case on.

I would definitely recommend this battery case to any S6 Edge user who doesn't mind the extra bulk of the case, doesn't want to carry around a power bank, and want some peace of mind knowing that their Edge will easily last the whole day and more. :good: :)​
