I just looked at my battery usage on my 4XL via the phones built in and via GSAM, and my bluetooth, when not being used draws ZERO% in both cases.
GSAM is showing zero since full charge, about two hours ago.
Phone is showing over the past 24 hours also shows zero even though I used BT for about two hours this AM for music while on a walk.
I have noted my ideas before on having to turn off functions of a phone to make it last longer. And I do not see why this should ever be necessary!
Do people turn off mobile data (LTE/4G) when not using it? Would people turn it off when the phone is sitting in your pocket and you are not on a call? Don't think so. Only time I can see turning off mobile data might be if you are in an area where you know you will never get mobile coverage and you are there for a day or longer. And I don't even do that and I camp in places cell service is non-existent, no wi-fi and only a Satellite phone will work for communications with anyone outside of shouting distance. And over a three to four day period, the phone still has power at the end of the trip. Not a great amount, but still power and on the way back home or to another location, I just plug it into the truck and let it charge. (Could plug it into trailer, have enough outlets, just never do.)
As for bluetooth...I have left my BT on for all my past phones ever since I stared using BT many years ago. I want it on all the time so that if someone calls I can pickup a BT unit of some type and turn it on and automatically connect to the phone. I want it on so that when I get in one of my vehicles, it automatically connects; I see no benefit of turning it off.
Same with wi-fi, why turn it off, unless in a place where you will never receive it same as for mobile data. However, I do the same for wi-fi as I do with mobile data, it remains on.
From my understanding when the phone fails to connect to mobile data or wi-fi over a set period of time it shuts down and just checks every so often. (And that coincides with when I visit some place that has wi-fi (store, Doctor's office, etc.) I might be there for anywhere from 1-10 minutes before the phone pops up with a note if I want to connect to wi-fi.
Doing some searching it appears these items pull an extremely small amount of amps when just left in the On position.
I guess, it is each to their own, but I for one, purchase a phone (car, truck, computer, gun, etc.,) to do the job it is designed to do with the components they are made with and within their design parameters. If a phone cannot maintain decent battery usage only by turning off the features on the phone you use; what good is it?
These are my views, my views only. If someone likes to turn features off and on; go for it. I understand, many like to turn things on/off on their phones; many don't.
For me, if the P6P does not hold enough juice to easily last a charge for a full day of my usage after a week; it will be sent back and I will move on to another phone. My 4XL, easily lasts a day of my usage and it is over 1.5 years old.
I will likely turn off 5G. For two reasons, one; not sure if I even have 5G around here; it was only a few months ago I actually gained cell service to my house thanks to a new tower built down the road to the NE and some modifications made to another tower to the SE, but do they have 5G? And my usual LTE connection is about 108 dbm; not all that great but it sure works, and outside the house it is better.
Two, don't need it at home; paid a small fortune to run actual internet cable to my house so no need for 5G.
But how much power does 5G take if not actually connected?
