Root [Verizon] Android OS eating my battery way...

[jyang86]

hi. so of lately, like just yesterday, ive noticed that android os is eating up my battery life pretty good. i have a stock verizon note 2 running stock everything, on 4.1.1. i use to can go for a good 25hrs, but since yesterday ive got only 16hrs. im always checking my battery, and usually screen is the one with the most usage, but i noticed its android os now. last night when i went to sleep at 1am, i swapped my battery and leave it on my bedstand at 100%. wake up this morning at 8am, its already down to 85%, which is NOT normal. usually it would still be at 100% or around 98%.

since ive picked it up last week its been running fine. i leave everything turned on, and to me, it should be, its a smartphone right? with everything on, i still get 25hrs. ive been reading up on this android os battery hog, but nothing really relating to me. so if anyone can help me, that'll be great.

It doesn't surprise me that the battery drops more than a couple per cent overnight, regardless- a couple things come to mind. First is- have you installed any new apps recently? If a battery hogging app isn't listed as using up the power then maybe there's a conflict/bug with it. Second- maybe the phone is working harder to find a signal- maybe wifi or cell signal isn't as strong lately.

If anyone can help me on this, I would appreciate it!! I just purchased a verizon galaxy note 2 and when I connect to my wi-fi, the note 2 keeps constantly scanning for wireless networks, even tho I'm already connected. How can I fix this...The customer service rep. at Verizon store says her's does the same thing and that it's not a product issue, that they're supposed to do that.. However, it drains the battery down, unless you set up all your apps to update manually...Any fixes and/or help would be greatly appreciated as I really don't want to send this brand new android back to manufacturer!!!

I will answer here but I think that this issue merits to have a thread of its own. Maybe the mods can move to one, please?
I read on T-Mobil's forum regarding a Galaxy S2 user asking the same question that as long as you are in the network settings section the device will actively scan for networks, otherwise when you are not it will only passively scan for networks occasionally.
Yesterday I asked a rep at a retail store to go into her Galaxy S3's network settings and hers was doing the same thing, at that point she called her co-worker over to check her Galaxy S3's network settings and it was also doing the same thing!
I am inclined to believe what the poster at the other forum said because yesterday morning I received a warranty exchange on my Note 2, I set it up to connect on my home network and I immediately went to the network settings and noticed that it was scanning for networks every 5 seconds. I was troubled by this because that was the very reason why a warranty exchange was issued to me. After seeing this on my freshly exchanged unit, I did a factory reset and got the same result.
I did not want to have a phone that was wasting precious battery power doing useless scans when it was already connected to my home network!
If anyone else knows anything about this situation I would be very thankful to hear from you, and if you hadn't noticed this before go ahead and check it out your Note 2.
You will see that yours is doing the same thing. It will scan for networks every 5 seconds whenever you are in the networks settings window showing that your phone is already connected to a network.
