Underground setting?

[tannins]

Acejavelin, that was the info I was fishing for. Makes sense.

Of course, I use airplane mode in this fashion. I was hoping there was a way not to since I do actually receive SOME communication in the area that is a problem. Oh well.

Is there a wifi network available when you don't have 4g?

I go to my parent's house in the mountains and have no cell reception.
I log into their home network and all seems well.

I haven't spent a lot of time up there since getting the rezound so I'm not sure if it is searching for a cell signal and thus abnormally draining the battery or not.

Just a thought in case it might help.

IDK if you would see the same amount of drain since data is the biggest consumer of power. I think that's why people who have issues maintaining 4G see a big drain even though they have a good cell signal. Thinking on microchip here, I wonder if forcing the phone into 3G would conserve enough power that our OP could leave there phone in regular mode while making these treks underground since they say that it's not a total lack of signal just broken enough that they see a rise in battery consumption? Just wondering? To do that; settings> more(under wireless connection)> model network(the words not the on off switch)> network mode.

OP could try Juice Defender.
I've had good luck with it improving battery life.
Not sure if would help in this situation but the most robust version seems very tweakable and full of options.

Otoh, this might be a case where the only solution is manual human attention.
Ever since I started using an electronic daytimer, into a palm pilot that I still use and into smart phones, I just keep it in my mind to maintain them regularly.
I make daily backups and I plug them in almost every time I'm at a desk or in my car for an extended period of time.

As a result, they are always at the ready, 24/7.

In this case, if I had regular places that I went to that had no signal, I would manually put the phone in airplane mode and turn it off when back in range.

Sometimes there just isn't the perfect solution.

Good luck.

Ok, dont call it sleep mode. Call it, I'm going to stop all processes that deal with communication until I get a signal again mode that stops all processes dealing with communication except looking for a signal.

Press power button for several seconds and then select power off ?

It is the best power saving mode keeping the screen off and the cell radio off. That's what you want, right? You want the radio off along with the screen off while in an area where you know you can't get a signal - underground in a sewer or a bomb shelter.
