I did a factory reset. It's been a complete PITA since then as it syncs my contacts with an empty contacts list, etc. I had to install a third party contacts saver.
The factory reset did nothing. I don't need to waste time at a Sprint store just to have them do another one. Putting the phone in "ultra" power saving mode does nothing. The battery monitor lies and says there will be 112 hours of battery life while it is draining 3% per hour.
Obviously there are bugs in the OS causing power drain. Reflashing will do nothing, just as the factory reset did nothing.
"after you did the factory reset did you add everything back or did you test it bare bones for a few hours to see if it was still happening?"
Yes. There was no change in the battery drain. As I have mentioned, I ran in safe mode. There was no difference, it still sucked power. The other way to disable all the apps is "ultra" power saving mode. And as I mentioned there was no change, it still sucked power.
It is not the apps.
Your "update just didnt load correctly onto the phone" is interesting. How do I fix it?
The only remedy from everything I have read is to abandon nougat and go back to marshmallow. Reflashing nougat will do nothing, just as factory reset did nothing, safe mode does nothing, ultra power saving mode does nothing.
I completely understand the situation. Please, let me ask, were you able to take the device to the repair store for review?
I don't have a store near my home. There may be one near work, but I don't have much extra time at work. I will have to go two stops on the Metro to get there.
I went in the Sprint store in Winchester this morning at 9AM. The young woman was very nice and looked at the phone. But she said they cannot reflash marshmallow. Nor can they reflash nougat in case that was not installed properly. She also said she had an older tablet on nougat that has increased battery drain when not in use. Like mine it is unrelated to any app as it drains just as much in safe mode. She said we simply have to wait for an update from Samsung.
