S7 battery life tanks out of nowhere

[bthornton84]

When my Galaxy S7 (VZW) is working correctly, I’m really pleased with the battery life. I charge it overnight every night, take it off the charger in the morning, and my only expectation is that it be able to make it through the day without having to charge until the next night. No games, no videos; just email, Facebook, text messages, and news sites. My phone used to be able to do this every day just fine. Best case scenario, I can put my phone on the charger at night with more than 50% battery left:



But lately, out of nowhere, my battery life has been basically cut in half. And the culprit isn’t obvious when looking at the Battery settings. The only thing I notice is that Bluetooth seems to run all the time. In the past, I blamed this on the Fitbit app; specifically, when I turned on notifications on the Fitbit. So I did a factory reset on my phone several days ago, reinstalled everything, and made sure to NOT setup notifications. For almost a week, all was well. And once again, at random, my battery life has tanked again—and Bluetooth is once again running the entire time the phone is off the charger. Not sure if Fitbit is to blame, but even after uninstalling the app, I still see the drain. The only way I've been able to get my all-day battery life back is to do a factory reset.



This is extremely annoying as battery life is half of what I got this phone for. Any ideas on how I can get to the bottom of this? Thanks!

Bluetooth does seem to be an issue for you here! I would probe a little deeper into the workings of the device in this way: do you know any other S7 users who are reporting a similar kind of battery drain? It sounds like you just got this phone, or have not had it for a long time... But you could always speak to your sales rep about whether or not they believe this is a software or hardware issue; and they may recommend a new battery or some other trick that may help. Good luck!

I also have noticed that Bluetooth seems to be using more battery than on my old S5 for some reason. Haven't dug into it yet and hopefully easy fix issued. But I do sync to fitbit also.

I'm not even 100% certain that Bluetooth alone is the cause of the battery drain. But whenever battery life is bad, Bluetooth has been on since the phone was off the charger.

Is there any way to find out what app (s) are using Bluetooth?
