Hey @Frenchfrywife ,
can you let your battery run down to below 50% from a full charge and then send us a screenshot of your battery usage? You can get this by going to Menu> Settings> Device Care> Battery> Battery Usage.
I can see that the radio app has been working in the background for 8 and 4 hours. Can you please ensure that you close the app once that you have ended with it and monitor the phone to see if this makes any difference?
Still having issues with my battery draining quickly. I attached the screenshot to my original post which you requested I try. Uninstalling the TuneIn app didn't appear to resolve the issue. I still have the screen running at 60hz, display is at about 20% and I work until 3pm each day so I am not spending much time using my phone, but it is still at approx 60% charge by lunchtime. I also put apps such as WhatsApp, Snapchat and Instagram to sleep when they aren't in use in case they were draining battery. It really isn't a lot of screen use for the battery to be draining so quickly. Again, I'm comparing the performance of a 2 year old phone with a 3650mAh battery which far out lasts my phone. So frustrating when it's a brand new phone.
