I Have notice that battery of note 8 drains quickly when switches for both WiFi and Data are turned on.
I turn both on for the purpose that when I am out of range of WiFi, data will turn on seamlessly, and when WiFi is available, it will switch back to it.
With both switches on, even when only WiFi is in use, the battery seems to drain quickly.
Battery life is tremendously improved when only WiFi or data Switch is on.
Any ideas as to what is the problem?
Main element to drain battery after screen is Device Idle.
Attachment: idea as to what I am talking about.

If you leave the WiFi enabled all the time. Your device will constantly scan for a network, which you are signed onto. That drains the battery. Unfortunately you need to disbaled WiFi connectivity when you are not gonna use it to preserve power.
You can disable mobile data connection while you are connected to WiFi. This is done throw developer options

One of the main powerdrains for the Streak 7 is the 4G Radio. It's constantly seeking a connection, which burns through juice rather quickly.
An app that helps with this is SwitchPro Widget...it gives you different toggle switches you can place on desktop to control aspects of your device.
I have a reboot button, battery indicator, wifi toggle and Data toggle on screen currently.
The Data toggle will turn off 4G/3G connection until you want to use it. I haven't had it running long enough to give feedback numbers as of yet, but will post some info later on.

Try it out.
Update: Also Airplane Mode toggle switch seems to work better at turning off cell standby, which shows 75% usage on battery.
2.5 Hours Unplugged now, and using Airplane mode has dropped my Cell standby to 51% usage vs 75% previously. I'm at 92% battery with decent usage during that time.

Yes, turning off airplane mode work like crazy, just sometimes turning on/off this mode takes a little time to reaction, therefore slightly affected the user experience because you need to wait for the data connection back from airplane mode.
I am using SuperPower, which is pretty good, but so far, I have not yet found a battery app that is compatible with Tegra dual core CPU, therefore the CPU control mechanism is not used by any.
JuiceDefender always causing data problem for me, not sure if you have similar issue.
Thanks for sharing! I do need a soft restart button at least!
Ok...8 hours unplugged now. Mostly on standby, as I worked 6 hours today. Battery is at 89%...left Airplane Mode on.
Considering all the complaints about battery life, this is more than acceptable. Going to do some gaming and Media stuff for next few hours, see how long it takes to drain it.
im not complaining about it. I can see about 3 hours of very heavy use.

One issue about the app linked. It may have issues with Gingerbread. Which you know we will prob have on Streak 7 soon and hopefully honeycomb sooner.
Superpower
I have been using Superpower also and it works for me. Has definitely increased battery life.
So do you just use ONE app (like super power) or you combinding them?
Ever since I did the LG update from B to D and baseband to 405 I have had issues with my wifi. Two things,
1. After a while wifi looses my home WAN network and will only reacquire it if I turn off the wifi then turn it back on. This did not happen before the update. It occurs whatever wifi sleep setting I use. I am consequently using much more 3G data than before.
2. Wifi now uses ~50% of my battery usage. Overnight it chewed through my entire battery. When I woke I thought I had BSOD but instead my entire battery had been used.
Any ideas what the problem might be?
cheers
Is it normal for 3g to consume more power than wifi?
/ Sent from my GT-I9000 on stock JVK /
yes it will consume more power
Standby or data transfer?
In my experience, they are similar in standby. but I guess it depends on the conditions.
Yes, it is normal. Whether it is on standby or in usage, it's definitely the case for me.
To my experience and observation WiFi consumes less power than while browsing/surfing on 3G.
Sometimes I spend all evening at home on WiFi (which automatically turns odd data connections on 3G/other) with little consumption. A friend of mine observed this too on his Samsung I5800.
I keep reading that mobile data is supposed to consume more battery than WIFI, but whenever I have WIFI on, I drop a percent every couple of minutes. And this is unusual, because I undervolt and generally have much, much less drain on mobile data.
When I check the battery stats, its "Android System" that is taking a lot of the percentage, not the WIFI itself. I think this is because my system is set to update only on WIFI or something. Does anyone know how I would shut this off? This only happens on WIFI, not mobile data.
Hey there, what firmware are you on?
Airplane mode on, WIFI on , sleep policy off.
18 Hours / 40 Percent
WIFI 42%
Phone Idle 35%
Display 13%
I ran my OG droid at home with wifi on since it came out and usage on the OG was typically 2-3% of battery. What gives?
Thanks,
alan

My battery is not the best either, and I think it's the WiFi scanning too frequently (if not constantly). I need to run more tests, but I feel like if you are not connected to a WiFi signal, you should turn WiFi off immediately. That's what I'm seeing anyways.
I have my phone switch over to WiFi when I'm @ home (I use Locale to automagically do it for me) and shut off when I'm away. I also have the search for open networks unchecked in the WiFi settings. I figure the constant scanning has to be eating up some batt.
I suggest using an app like auto wifi toggle just checks for wifi every so often then turns it off if it is not found and if you have no wifi connection it turns off as well.

Open Network notify is turned off, and I do use the native wifi toggle. Wifi on at home, airplane mode for the 3g/LTE enabled.
