Hey, I recently signed a 2 year contract once again with rogers and received a s6 64GB gold version. After using it a few days, I realized how HORRIBLE the battery life is comparing to my OnePlus One. I leave WiFi on and lose ~20% overenight!!! This NEVER OCCURS with the OnePlus One. I don't know how many people are having this issue but this is driving me nuts!
Anyways, this is my rant about the phone. Great phone.
@Paf What other functions do you have running? (Bluetooth, NFC, Active Wallpapers, GPS)
An investigative option would be to check the Battery app and confirm what is using the most juice.
@RogersDarrell@ShakTiburon I found out the real culprit. After installing Gsam, I was able to see the usage in detail. Turning on Wi-Fi in general caused the battery drain. This is a huge compromise to me since I have a 1GB data limit. I don't think I have any other solution to fix this besides having WiFi shut off entirely.
That being said, I usually have Location turned on and brightness on auto. Everything else is on default in settings. I don't see how this should affect the battery in any significant way.
EDIT: Lost 0% when WiFi is turned off overnight....
Now, is your WiFi connection stable? If the device is always searching, disconnecting and reconnecting then yes; that would be a major battery drain.
Another thing, if it's determined that the software itself is not properly managing the battery requirements for WiFi; then I wouldn't be surprised if it's addressed in Samsung's next Maintenance Release for the S6.
Sorry for the late reply. @RogersDarrell My WiFi is stable and maintains around 4-5 bars of signal. This issue is driving me nuts! :S
@ShakTiburon I would bring my device to the nearest Samsung Service Center in my city if it wasn't for the unwelcoming atmosphere and poor service. But I am confident that it's not a hardware issue. My router runs fairly stable at 2.4GHz frequency bands and never had any issues. The drain only occurr when turning on WiFi no matter which network I use.
However, I did noticed that reception tends drop into the 2-3 bar zone when LTE is off. I don't think this matter since WiFi is the main problem for battery drain.
I did some research and found the solution for this problem. BUT....it's only for the T-mobile version. It can be fixed by going into phone>more>settings>LTE over phone *off*.
Seems like I have to wait for OTA unless anyone has an alternative solution for rogers version.
