If you’ve noticed slow data speeds or poor cell reception on your iPhone 4 or 4s, it is likely due to a limitation in the phone’s hardware. Prior to the iPhone 5, Apple built their devices with only 3G capabilities even when 4G LTE was available. What this means is that these devices will not get LTE data speeds and are likely only going to get slower as new cell phone technology rapidly gets faster. Unlike most smartphone issues, this is a problem that can only be resolved by purchasing a newer device.
If you are unable to connect to Wi-Fi or if the Wi-Fi option in the settings app is greyed out you likely have an issue with the Wi-Fi antenna screw. My Broken Phone can replace this screw to take care of this issue for you in less than 20 minutes. Sometimes, the controller chip on the motherboard for wireless functionality has gone bad. If this is the cause of your Wi-Fi issues then, unfortunately you will need to purchase a different device.
One of the most common batteries we replace at My Broken Phone are those in the iPhone 4 and 4s’s. Released in early 2010 and late 2011 respectively, the battery inside your iPhone 4 or iPhone 4s is likely nearing the end of it’s life span. Contrary to what many people believe about iPhones, the battery is replaceable by a knowledgeable and trained technician. If your iPhone 4 or 4s battery drains doesn’t make it through the day, stop by your local My Broken Phone repair center and have it replaced before it goes completely dead!
