Sudden large battery drain

[greycobalt]

I've been using my S4 a week and a half, and I've loved it, and been pleasantly surprised with it's battery life. However, yesterday and today the life took a sharp turn for the worse, and drained to half battery without any use by the middle of the day. I use GSAM, but the logs are gibberish to me, so I was wondering if anyone here could tell me what's going on. Yesterday, the Android OS Kernel was the main culprit, today the Bluetooth Share is.

I was going to post them as plain text, but they're pretty long, so I'll attach them. If someone wants me to post them plainly, let me know. Thanks in advance for your help!

I haven't gone through the logs, but did you have to do an OTA update after you got the phone? I had an app go rogue after the OTA update (ironically it was Battery Guru) and I was missing the WiFi toggle (which was added in the update) so I did a factory reset. That solved all of the problems.

I didn't do any OTA update after I received it, at least not to my knowledge. Do they download/install automatically? If not, then no, I did not.

I had a similar issue. The Gsam app sucker showed that an app was initiating wake lock for audio in/out. Gsam provided the app UID but I couldn't find the correlation from the app UID to a particular app.

Anyway a standard reboot (not factory reset) fixed the problem for me.

I had to turn off Google location Services to fix mine. Was a gps drain. I'm hoping to find another fix so I can confine l continue to use Google Now...
