Update
There are cut outs on the bottom, so the sound is forced out of the bottom of the phone, I prefer it more than the sound coming out the back.
I've been using this battery for a while now it's flawless!
The single downside (apart from the obvious weight and size that people seem to argue from the get go)
the sound isn't as loud as when using the stock battery, however the space between the bottom of the battery and the handset itself has enough room to fold a piece of card to ensure the speaker is kept clear and thus the sound reaches the bottom ports in the case as desired, this may not sound pretty or a particularly advanced method, but it works and you can't see this method with the case on anyway.
Give it a try I assure you, you will notice the difference!
As for the only charge once a month on the instructions... I contacted ZeroLemon...
To allow the battery to fully drain to 0% once a month, the other times charge from 2%
I always charge around 2-5% and allow it to die fully once a month.
The other thing you can do when using this, assuming you're rooted...
Two apps; Android Tuner & BatteryCalibration
Android tuner > Battery Manager > Calibration > Manage > Edit Current Battery > Name: ZeroLemon Capacity: 7500
BatteryCalibration will tell you exactly what to do. However, Android tuner has been the more accurate of the two methods.
* In both methods ensure battery is full (100%) before doing this.
Hope this helps.
