I am experiencing accelerated battery drain since receiving the last OTA update. I have not made any changes to the device settings and I have the exact same apps on the phone as before the update. The acceleration is significant in my opinion. Prior to the update, I could get 25+ hours of moderate use, including 6.5 hours or so of screen time before the low battery warnings would start popping up. After the update, I am getting 15-17 hours of moderate use with 3.5 or so hours of screen time. On days that I want to use the phone heavily, I have to charge it twice in a day. These are the numbers when I'm on Wifi. If I have to be away from home or work where I have no Wifi, the numbers are worse. Let me add the top battery users as found in the settings menu prior to my last charge: Battery at 6%, Screen used 70%, Device Idle 8%, Android OS 5%. So nothing is really putting great strain on the battery outside of the screen. Let me also list the steps I've taken to address the post-update issue: 1. I contacted AT&T via chat, but was referred to Samsung to discuss the update and AT&T offered a used replacement (not a viable solution to me). 2. As directed by Samsung, I performed a factory reset via the settings menu, then charged the phone for 3 hours. 3. As directed by Samsung on a second inquiry, I performed a hard reset via the recovery menu, then charged the phone for 3 hours. One more note: I have been given the typical tips to conserve the battery (turning off background data, GPS, Bluetooth, Smart features, etc.), so we can skip those. I utilized most all of those tips and no one I have spoken to wants to recognize that my phone's settings are set to where they were and address the the apparent issue, which is THE UPDATE. So my question is, what is the solution? Did the update change something in my settings that I've missed? The only real changes that I noticed (other than the drain) after the update were the battery manager icon and the translucent status bar. The post-update drain issue is prevalent on forums across the web. Does anyone on this forum have a solution? Thank you.
