Q: The battery life on my new iPhone 7 is HORRIBLE. What the ****?
Seriously, is this a joke? I even turn on low power mode in the morning and have to charge it at least once during the day.

Did you restore this device from the backup of an old device? Go to Settings>Battery and see what app is using the highest percentage of your battery. More than likely, and this happens a great deal with all of the iOS updates, you have a process or app that is stuck attempting to perform a function. User troubleshooting is restart, reset, restore from backup, restore to factory; testing after each step. Sometimes in the update process, especially I've seen if attempting this OTA, this can occur. Generally the restart or reset will fix it, but if you have to restore from backup, make sure you take a current one. If you have to move on to restore to factory, then test it for a period of time before attempting to add any additional content back. You should see an improvement.
