How do I fix unstable phone calls, slow 5G, and warm iPhone 17e?

With my iphone 17e (which I bought ~3 months ago), many phone calls are not stable, nor is wifi connection, and 5G is very slow. It gets warm (warmer than my experience with older iphones) quickly. Anyone having similar problems?

📱Facing iPhone heating issues? Here's what worked for me on my iPhone 12 Pro:

1️⃣ Backup on iCloud/iTunes

2️⃣ Log out of Apple ID

3️⃣ Erase (Keep eSIM Data)


❌ DO NOT restore from backups! Set up as new iPhone. Wait 2-3 days - no issue! That Indicates...

✅ No hardware/ iOS issue


Now...

📦 Restore data gradually

🔍 Find app/settings causing heat




My experience says this is purely caused by some third-party app that you may have installed.


I am not aware of the ambient temperature in which you are using the iPhone. However --> Keeping iPhone, iPad, and iPod touch within acceptable ...


Store the device where the temperature is between -20º and 45º C (-4º to 113º F). Don’t leave the device in your car, because temperatures in parked cars can exceed this range.


Use iOS devices where the ambient temperature is between 0º and 35º C (32º to 95º F). Low- or high-temperature conditions might cause the device to change its behavior to regulate its temperature. Using an iOS device in very cold conditions outside of its operating range might temporarily shorten battery life and could cause the device to turn off. Battery life will return to normal when you bring the device back to higher ambient temperatures. Using an iOS device in very hot conditions can permanently shorten battery life.

Please check the bandwidth that you are getting. Disable WiFi before running this Field Test.


You may check the current LTE band/5G/4G/3G by dialing *3001#12345#* pressing the call button and then selecting the Serving cell info option

See the pic below which is self-explanatory



E, 2G, 3G, 4G, LTE, VoLTE, and 5G all are Carrier Specific features. Contact your Carrier (Cellular Service Provider), the agency that issued the SIM / eSIM to you. About the LTE options on your iPhone - Apple Support (IN)

What Call? On an iPhone, you can make and receive various types of calls. Here are the different types:


  1. These are standard voice calls made over the cellular network. They utilize your carrier's voice network to connect you with other phone numbers. Allow phone calls on your iPad, iPod touch, and Mac
  2. FaceTime Audio allows you to make voice calls over Wi-Fi or cellular data using your internet connection. It provides higher audio quality compared to traditional cellular calls.
  3. FaceTime Video enables you to have video calls with other FaceTime users. It uses the front or rear camera on your iPhone to transmit live video during the call. Use FaceTime with your iPhone or iPad - Apple Support (IN)
  4. VoIP (Voice over Internet Protocol) calls use internet connectivity to make phone calls. Apps like Skype, WhatsApp, Viber, and Google Hangouts utilize this technology, allowing you to make voice and video calls over the Internet.
  5. Some carriers support Wi-Fi calling, which allows you to make and receive calls over a Wi-Fi network instead of relying solely on cellular coverage. This can be useful in areas with weak cellular reception. Make a call with Wi-Fi Calling - Apple Support (IN)
  6. The App Store offers numerous calling apps that utilize different technologies. These apps can provide additional features and options for making calls, such as international calling, call recording, and more.


It's important to note that the availability of certain call types may depend on your iPhone model, iOS version, and carrier.
