    IDLE bluetooth uses very little energy and NFC uses almost none. ACTIVE bluetooth uses a fair bit, as does any active RF interface (no matter what sort.) In order of consumption (lowest to highest) they are NFC, BluetoothLE, Bluetooth, WiFi and Cellular. There is a modifier on this in that WiFi (and LTE) can move a LOT more bits than Bluetooth over a given period of time, so the question also becomes what is keeping the transmit key on -- bits to move or time. Finally, when it comes to cellular radios the maximum legal handheld power output is 600mw but that is under control of the tower -- if you're close-in with a good signal it is throttled down a lot.
    Know anything more about active vs passive bluetooth? Bluetooth is definitely the culprit for me; battery might drop 5% max overnight with bluetooth off, but about 25% with bluetooth on. It's not connected to any devices when it is on overnight, but it might be searching or some such. Might there be a problem app that is causing the activity (I hear GasBuddy is a problem, but I have never installed that), or is this a system behaviour that can't really be modified? Making the convenience key a bluetooth toggle is a great workaround, but if there were a more fundamental solution that would allow me to keep bluetooth on, all the better.

    This is fairly common and extremely hard to nail down. Even apps that shouldn't have ANY interaction (and don't "formally") can be responsible -- Gas Buddy is one of the notorious ones and the people who developed it should be BBQ'd and EATEN.

    IMHO Cool ought to consider a factory reset, reloading ONLY GSAM + OS Monitor (important: NONE of the other apps currently on the unit) and then a re-test. If that gets the same result then I'd swap the device.
    Hah. Was writing a response to your other post as you wrote this; thanks!

    They all have to come from the same time. This is why; I snapshotted these both within a few seconds.

    This is from my morning thus far. Notice a few things. Zero on phone, 11 minutes of screen time (which is responsible for HALF of the 1% consumed), WiFi, Phone standy, Held Awake and Bluetooth responsible for a good part of the rest (about 20%) and the rest being apps.

    Now among the apps almost all are system related, which is expected (the phone IS on standby and has all the radios up.)

    You can't take *piecemeal* snapshots after the fact and have them mean anything. It has to be from a given point in time with a clean base, and as a result of the OP's not doing that as requested I can't give a clean opinion on the OP's situation. A factory reset appears to be in order, however, and then a reload ONLY of GSAM + OS Monitor, and a re-test this time with the snapshots taken at the same time so the data is coherent.

    BTW another option is to (1) charge until full, (2) turn off while plugged into the charger, (3) disconnect the charger and then (4) let the phone sit, TURNED OFF, for several (~4-6) hours. Then power it up.

    If you lost 20% of the power then since the phone was OFF it's the battery. If it boots up and is somewhere between 95-100% by the time it gets fully started up, the battery is NOT leaking at the rate you're seeing and the drain is coming from elsewhere.

    To answer your other inquiry, I did factory reset the phone, and let it sit idle for a few hours with absolutely nothing installed, and nothing changed.

    Does it lose charge if starting at full and then turned OFF for 4-5 hours? If so that's definitely the battery self-discharging.

    No, I meant after the first time I did a factory reset, I installed nothing, and no accounts. Disabled everything I don't use, and the drain, while powered on, was about the same.

    I haven't done a voltage leak test.

    Well now that extrapolation is from your previous days. The top-line (actual consumed), assuming cell RF was turned on, is not terrible. About what it should be in fact. So.... this looks app-related.

    I just now realized that my emails aren't coming in unless I restart the phone or put on airplane mode.

    My sync interval is set to never, and I have use push if supported enabled.

    I use Comcast imap email.

    Likely because you set the sync interval to never. I don't know much about comcast mail, so don't know if it supports IMAP IDLE. My guess based on your description is that it doesn't. Set a sync interval.

    Yeah, basically none of the big cloud providers (or the cable ISPs for that matter) properly support IDLE. Some butcher it in ways that will harm battery life and some just butcher it period. Exchange/ActiveSync is also subject to some of the same bogons, but not nearly as many. If your ISP allows that option you might want to try it, or set a polling interval.

    I'm starting to think I should focus more on what this says as opposed to the stock Android information.

    5% in an hour isn't horrible IF THE DEVICE IS ACTIVE.

    Here's another question -- if you let the phone sleep for a while (10-15 minutes) and then wake it up, what's the power consumption show on GSAM *immediately* (not after it has time to refresh)? It should be very low (single digit or low-double-digit milliamps.)

    Gimme a few. I'll put the phone down with gsam open and pick it up and take an immediate screen shot

    That's 10x what it should be while sleeping (the phone's electronics have an actual current meter in there; it's not a guess.) That's not the battery, it's something not going to sleep and it's likely an app.
