Quite a long time ago, we covered a Cydia tweak by the name of Volume Booster, which did a pretty good job of enhancing the maximum volume level of iOS devices. iOS has come a long way since then, but some things haven’t improved a great deal. While the bottom speakers in iPhone can play sounds at a pretty high volume, many people still complain that the in-call volume could have been a lot better. Since iPhone 5 comes with hardware that is different from any of its predecessors, a lot of users assumed that the call volume issue won’t rear its ugly head in it. Sadly, this isn’t the case, and in even slightly noisy environments, users are hard-pressed to understand what the person on the other end of the line is saying, no matter how much they crank up the volume. Volume Amplifier is a new tweak that doesn’t tinker with the bottom speakers on an iPhone, but only deals with increasing the in-call volume, making it possible to increase the volume by up to 200%.
You don’t have to configure Volume Amplifier after installing it; the tweak doesn’t even have an app icon or menu in the Settings app. To bring Volume Amplifier into action, just keep hitting the volume up key the next time you make or receive a call. The first time you use Volume Amplifier, it displays a few basic instructions regarding the tweak’s working. Keep going even after you have reached 100% volume, and you will notice that a new amplification bar gets added to the volume HUD (surrounding the default bar). Now you can keep pushing the volume key until it reaches a satisfying level. In our experience, keeping the level between 120% and 150% turned out to be perfect, and anything more than that started distorting the sound.
Although Volume Amplifier is a pretty neat tweak and there aren’t likely to be any serious issues with it, you can still revert to your device’s normal volume level using an Activator gesture of your choice. This gesture can be configured by heading to the Activator menu in the Settings app, and is usable only during calls.
We have already seen a few tweaks that work only with iPhone 5, but Volume Amplifier’s limitation to only the latest iDevice is a bit confusing. With FullForce and Screen Extender, it is understandable that users won’t need them on any device other than the iPhone 5. Volume Amplifier, on the other hand, handles an issue that has been plaguing almost all iOS devices for a long time. According to the developer, the tweak will be made compatible with iPhone 4 and iPhone 4S if enough people ask for it. Volume Amplifier costs $1.99, and can be found in the BigBoss repo of the Cydia store.
