Nothing is more frustrating than reaching into your pocket to grab your phone only to notice you have a notification waiting for you! Why is it that when your vibrate is clearly on, you didn't feel your phone? It's maddening! In our humble opinion, we'd rather have a vibration be more powerful/annoying than weak/unobtrusive. When a text comes through, we want to be brought to our knees by the seismic force of the iPhone's motor. Instead, a text simply flies under the radar for a full 1, 2, or even 3 minutes it takes before we check our phone out of habit anyway. This is unacceptable so after the jump we've wrangled some ways to hopefully improve your iPhone's vibration so you're not missing out on those crucial notifications of you being tagged in an album on Facebook instantly as they happen.
First and foremost, we should stipulate that obviously we don't want our iPhone to register a 3.2 on the richter scale as a text message comes in. In fact, it's likely that even a small boost in vibrate intensity could damage the other innards of the phone. So to begin and to start out with perhaps the most easy solution, why not simply restart? Cnet tells us a simple restart could magically store the phone's vibrate to full power. We're not exactly sure what it does. Calibrates the motor? If anyone wants to take a stab at it we'd love to know more.
Another more advanced alternative would be to jailbreak your phone and change the code which dictates the vibrate duration (currently at a fraction of a second) to something a bit more sustained. For those still unaware, jailbreaking your device is completely legal in many countries, including the US. If you're unfamiliar with jailbreaking, there are many sources online that could give you more information about the procedure. Once you've successfully jailbroken your phone you will need to learn how to alter the code to a new duration. For that you can watch the above video for one way to approach it.
But if software simply isn't fixing the problem, it could be a hardware problem. Our first iPhone had an issue where it literally did not vibrate and the toggle switch was nonfunctional. This was not an uncommon, apparently. We went to the Apple store where a member of the genius bar quickly looked over our iPhone and gave us a new one. So if you're confident you have a hardware issue on your hands, you will likely be given a replacement iPhone on the spot. The only problem is having to schedule an appointment with the genius bar which isn't always an easy thing to do. And for those tinkerers out there, eBay is filled with replacement motors and volume toggles so you could do all the work yourself it your warranty is already void or you're just that daring.
