For the last month, my phone's battery life has become shorter. It used to easily make it through the day, now it often needs a charge by evening. This is going to be a problem, because I'm planning to travel, and want to take pictures with my phone, and may not have a chance to recharge during the day.
When I check battery usage in the Android settings, the T-Mobile app is now always at the top, far above any other app. Today, it says the T-Mobile App has used 41% of my battery (when the phone dropped to 15% charge by 5PM), using 996 mAh. The next highest app used 5%. It wasn't like this until the last month.
I do remember an update to the app a while ago, and was prompted whether to allow diagnostics, etc. I initially allowed this. Then, I tried to turn this off, in case the data collection was using my battery. I went to app settings, diagnostics, and unchecked agree under Device Data Collection. When I do this, the next button changes to a close button. I press close. But if I reopen the menu, agree is checked again. I'm not sure this is really turning data collection off. Is this data collection what's consuming my battery? Or is there something else in an update to this app that's using more battery?
I would appreciate if somebody could figure out why this app is draining my battery, and how to prevent it.
My phone is LG-V30, T-Mobile version with all T-Mobile updates including Android 8.0.0 Oreo, postpaid.
