[Galaxy S 4 Accessories] Aitch:
OK finally received mine today! First impressions - it kicks ass!

Starting with the case, which is damn near perfect in my opinion! (I got the black version).

1) It has a nice texture which makes the phone easier to hold but is not so grippy that it sticks in your pocket and makes it difficult to take out.

2) It has a tiny ZL logo on the back but sits perfectly flat and doesn't move or rock when tapping the screen.

3) It nicely overlaps the front of the phone so it covers the vulnerable plastic edge and gives about 1mm of clearance to the screen when put face down, so it doesn't get scratched.

4) The holes are all perfectly accurate and don't obstruct anything, especially the headphone jack which is what I was worried about.

5) The power and volume buttons are completely covered so don't give much feedback when pressed and seem to require harder pressing to activate. But I actually like that as I rarely use them anyway and it stops them getting hit by accident.

6) I took pictures with the case off and the case on. I couldn't tell any difference what so ever so I reckon the camera quality isn't impeded in any way.

7) I use a tempered glass shield over the screen and the case fits just fine with it. In fact it looks like they were made for each other as the edge of the case butts up perfectly with the edge of the glass.

Now on to the battery itself.

1) It naturally does add size and weight to the phone but I actually like that now! It feels nice and solid in the hand which makes holding it easier. Indeed, its the same thickness as phones we were all raving about just a few years ago! Thin phones are for fags lol!

2) One of the big criticisms was about sound so I tested it with some songs to check the bass and treble and overall volume. Personally I can't tell any reduction in quality or volume at all. Actually I think it sounds a little better! However I usually use earphones when listening to music so my main concern was that the ringtone remains loud and clear, which it does.

I noticed on the battery that there is a small indentation over the area that covers the speaker. This extra gap seems to let the sound out just fine. I don't know whether this was on the earliest batteries or whether ZL have only recently started doing this? It might explain all the complaints?

3) The other criticism was about signal strength. I don't know much about this but I went in to Settings>Status and noted that Signal Strength was stable at -79 dBm (huh?) with the standard battery. With the ZL installed it changes every few seconds, ranging from -75 to -83 dBm. I have no idea what this means but the battery is obviously having some affect.

The thing is though, I still get a solid four bars so I'm guessing it doesn't make much difference overall, at least when you are in an area with strong coverage. I'll test the battery in a low signal area, next time I go out to the countryside.

Anyway, so far so good. ZL say I need to charge it for a full 12 hours first and then recharge/discharge completely at least 6 times to get the best performance. This could take some time lol!

I've uninstalled all my Battery Saving Apps, turned off Power Saving Mode, am keep Sync, WiFi and GPS etc permanently on, and have jacked up the Screen Brightness to max! I've even turned on all the annoying 'Smart' features lol! Lets see what this bad boy can do!

Man it feels good, no more limitations on using the phone too much in case it dies on me half way through the day, no more crippling its functions to preserve power, no more mudderfuggin bullship! I'm finally going to be able to use this (expensive as hell!) product just how I want to! Free at last, free at last, thank god almighty, free at last!

PS - I seriously can't wait for my Wireless Charger to arrive now!
