    So I've read all the threads about battery life, and it seems most experience about 6 hours of on screen time and like 16 hours of standby. I seem to be losing percentages of battery life with my phone just sitting. Almost 5 percent per hour. I end up with about 4.5 hours of sot and maybe 14-16 hours of standby. So I switched over from an iPhone 8 plus, and my questions are these:

    1. Are my usage times considered long for Android? My plus could go a day and a half with usage and be ok. This phone seems to just suck battery just sitting. I have aod on but only during the day, not even using the full screen res (using 1080).
    2. I've read about BK disabler, are there that many rogue apps that are causing this kind of drain? Is it worth going thru the trouble of using something like this to help out?

    Looking forward to using the phone, I love some of the features, although I'm still getting used to android, been on ios for years and years and years. I just don't want to cripple the phone either just to get a battery that lasts more than just work and then the drive home.

    I don't think you should be losing 5% per hour if you remember doing nothing unless your cell signal is terrible.
    The first thing I'd do is to check to see which apps are using the battery. Go to Battery and then click on battery usage andJust got my Note 8-screenshot_20171208-115227.jpg you should be able to find out which apps are using power.

    5% per hour for me is high... I lose between 1-2% per hour. Otherwise SOT doesn't sound bad. But give it a week or two or three for phone to get adjusted to phone, get your apps in and get some charge cycles into the battery.

    Can you experiment to see if your device drops battery significantly over a 24 hour period when it's powered off? If so, I would have the phone serviced and checked for a power draw perhaps caused by a firmware issue or a short on the board.

    did you take the security updates? apparently the last one, November, has an issue that can drain battery prematurely if wifi left on. mine lives mostly on a charger so I'm not affected here at my home office. I need to test on a long day like the last time I tested it while out and about.

    I believe I did take the last one. I wonder if I should turn wifi off and see how it does. I called Samsung, but they were not much help. They told me to restore the phone as new. I did initially set up the phone using smart sync from my iphone 8 plus. I wonder if that would have anything to do with it.

    I just got N8 from AT&T and first thing it did was ~350MB update that brought it to Nov 1 security patch level. Then hours later a small update (took 4 minutes total) "Security Enhancements for Android Status" SEPH_SECMOBILE_7.1.1_0003 Mon Nov 13 11:50.

    Very sweet!

    I had the same issue when I first got my note. I would have horrendous idle drain, and would average about 2.5h SoT. A factory reset, clearing the cache, and setting up as a new device completely changed everything. Currently sitting on 6h 30m SoT with 17% battery remaining.

    I'm in the same boat as you my friend. I switched from the iPhone X, which would last a full day with a good amount of usage. The Note 8 is not holding up to that, the battery % drops so quickly. An hour drive last night and lost 3% doing nothing. Please let me know if the factory reset helped you, I did the smart switch from my X to the note 8 so Idk if that could be the issue

    battery. it' has been reported and Google knows, but has said nothing. assume a fix is coming once they get their act together. and yes, users have reported battery drain. this IS the issue, as I understand it.

    Yea, you should be getting a full day easily from your Note 8. Something is up. Probably the bug you mentioned. The battery on the phone is very good to excellent.

    So I think the reset did the trick. I'm guessing the smart switch may have jacked some things up. Here is where I'm at currently. Took the phone off charge at 0230 this morning and still doing great! This is more along the lines of what I was expecting. Hope this helps!

    just verified the battery leak on wifi. I used to be able to do a lot and only lose 1% or 2%. this morning after doing hardly anything it was at 88%. it's never gone that low for me. I have spent hours on it while driving and streaming and it was still only at 94% when I got home. google messed it up for sure.

    I'm at about an hour. It's not much, but my idle time is what has really improved. I was losing over 5% an hour before with the phone just sitting.

    Shoot that's pretty decent. Don't read into battery percentages too much. Apple inflates the 100%-90% and then tracks pretty regular until 10-5%.

    I feel like the battery shouldn't just be dropping like that with nothing going on, and yes I know there is background activity with apps sync'ing but most of that is turned off. I just wanna get more then 3-4 hours of screen on time and still enjoy AOD... is that to much to ask lol
