Ok today I got massive battery drain, nearly empty after 8 hours.
The culprits are
Datacounterwidget (26% - used to keep track of amount of data I use each month)
WiFi sharing (18% - what is this? I dont think Ive used this before)
Openwatch (14% - bluetooth connection app to my bluetooth watch - didnt use it today)
Display (14%)
Android System (9%)
These numbers seem pretty strange to me, usually it will be screen about 45% android system about 30% and the rest split over the other things.
I have noticed wifi sharing pop up before and take a sizeable chunk out of the battery and I am thinking that may be the cause of the massive battery drain. Datacounter widget has never been up this high before and I think is just a by product of the wifi sharing.
Anyone know how I can prevent this from running? Or what it is?
Thanks
WiFi sharing is that not letting others use your WiFi connection as a free access point .

That's what it sounds like to me but I haven't set that up :S
Can't even see an option for it (well I see options for wifi hotspots but this and tethering are disabled)

My observation is that WiFi sharing and WiFi sharing manager will start in the background as soon as a WiFi connection has been established. They remain in the background even after you've turned off the WiFi and continue draining the battery. I've formed the habit of manually stopping both WiFi sharing and WiFi sharing manager every time I finished using the WiFi and they no longer appear in the battery-eater list. I've been wondering whether this could be automated and even better, when the WiFi-sharing battery drain will be fixed.
I have turned off the positioning by network option and now wifi sharing dosent appear on the list anymore. ... so i think it has something to do whit this

use Titanium Backup and "Freeze" Wifi Sharing... bam! not eating battery anymore. plus if I need it I can just unfreeze it.
Hi all,
The Wifi on my SGSII is constantly scanning even though it is connected to my home wifi network (a WPA/WPA2 PSK secured connection on a G band router). The signal strength is "excellent" and I have the phone sitting right next to the router. Further, I have network notification turned off ( unchecked) and under advanced settings, my Wifi sleep Policy is set to "never".
Sprint users have reported exactly the same problem on the Epic Touch 4G" (http://forum.xda-developers.com/showthread.php?t=1272226 ). Has anyone else been experiencing the same issue on their ATT SGS2 ? I would be very grateful if someone could post a solution for this issue.
Thanks in advance

PS: My wifi setting screen looks like this genteman's ( except i have network notification turned off)

Scan rate is bumped up significantly when you're in the settings menu.
Have you confirmed via logcat that it's scanning frequently outside of the settings menu? It shouldn't be in that case - but without logcat it's almost impossible to tell.

Entropy,
What should I be looking for in logcat? I have Betterbattery stats installed and according to that, Wifi scan time is 8+ hours even though Wifi on time is only 2+ hours. That doesn't seem to make sense, but what do I know.
I am running UnNamed 1.3.1.

I believe BBS is reporting scan time improperly. I've seen that in a few threads.

You're probably right, except now scan time doesn't even show.
I have also observed this on my phone.
I have a Samsung Galaxy IIs, using a Sony Ericsson MW600 BT handsfree as well as a Pioneer car Bluetooth handsfree system.
I have not measured anything yet, but I notice that when the Wi-Fi scanning is going on, I get significant disturbances on both of my Bluetooth hands-free sets. Listening to music is without a hitch, but talking on the phone (Norwegian GSM - operator Telenor) is terrible.
i also noted this after installing the OTA update to 2.3.6 today. I just rooted mine yesterday after reading 54+ pages to make sure i understood everything. i had a cappy and loved installing new roms but have not taken the plunge yet on the sgs ii. I haven't noticed a huge difference in battery yet, but it has only been a couple of hours since the update.
What ROM are you running? You can edit the build.prop to change how often it looks for networks. It is the line "wifi.supplicant_scan_interval=xx". I set mine to 180 which is 3 minutes, some ROM's set it really low. Also the scan rate is bumped up significantly when you're in the settings menu like Entrophy said.
Hi,
I had the same problem where my WIFI was fluctuating.... I dont know if this is the problem/ solution but this is what happened...
My SGS 2 is already rooted and unlocked. I had flashed the Entrophy DD 12/23 first then I had flashed Unnamed Custom ROM. After rebooting the phone, I saw the Wifi was not stable. So I again did a "Wipe Factory Data Reset" and "Wipe Cache Partition" and then installed the Unnamed Custom ROM from the SD Card. My Wifi is pretty stable now.
I am not sure if you guys had this issue when flashing a ROM but this seemed to fix it.

I have written about this wifi-battery drain a while back here in XDA.
When I used to have my Nokia symbian cell phone I used to flash custom roms
and there were a lot of nice new features after flashing.
A couple of the really nice battery saving mods were:
#1: added option to change the amount of wifi milliwatt output from 18 milliwatts (default) to 3 milliwatts
which is more than enough if the phone is no more than 20-25 feet from the wireless router.
(the mod gave the option of 3mw,6mw,12mw & 18mw)
Saves a lot of battery life.
Don't know why none of the DEVS have addressed this issue yet.
#2: added a mod so once the wifi establishes a connection it no longer scans
at all unless the connection is disconnected or lost.
So in other words, the phone only scans for wifi until it connects.
Right now I am connected to wifi with my phone and yet in settings it displays "scanning"
non-stop-constantly even though in wifi settings it displays "connected".
Why should the phone be scanning for wifi if it's already connected? (I have no idea).
Don't know why none of the DEVS have addressed this issue yet either.
Both of these mods really made a noticable difference in battery life
for for me since I do use the wifi feature in my phone a lot.
Hopefully one of the DEVS can look into these issues soon.
Now someone mentioned wifi constant scan, I noticed mine is doing the same thing. I leave the wifi setting screen on, it re-scans every 3 seconds!

Power control - Not likely, unless there is some documented power control already in the driver it's not going to happen. We're in a bad enough state as it is trying to make the chip not fire interrupts at 1 Hz on the Infuse.
Broadcom is one of the least open source friendly chipset manufacturers on the planet - their drivers have NO comments or documentation whatsoever, and datasheets are not available.
The rescan stuff is probably only addressable on Cyanogenmod, messing with it would require source code for the userland wifi management stuff.

As stated earlier in this thread - this is by design. It is assumed that if you're in the settings screen you want to change networks and have an up-to-date list.
I also am having this problem. I am running the rooted UKK6 from entropy512. After turning on my wifi, my battery drained from 90% to 70% in 5 hours with no use. My android OS is running at 80-90%. I don't have any extra apps except for 3g watchdog and CPUSpy and BBS. I do have Go launcher and GoSMS installed. As soon as I turn wifi off, i can see my battery level off under settings. I have searched for the last 2 days for a "fix". no luck.

Try doing a clean flash using "wipe data/factory reset" in CWM
recovery and then see if the phone has normal battery drainage.
(which it will if you flash the UnNamed v2.2.1 custom rom)
Then install one app at a time so you can find out exactly which
app is the culprit that causes your excessive battery drain.
This is the best way to trouble shoot battery drainage issues.
You will see that your battery drainage issue is not caused by
the custom rom, but it is caused by a few apps which are just
not very battery friendly.
The UnNamed v2.2.1 rom is the best custom rom currently
available for our i777 phones and it has outstanding battery life.
Good Luck!

This has nothing to do with this thread - This thread is talking about wifi scanning.
Drain problems - read my known battery drainers thread. A lot of people are having problems, there is no fix, and there won't be until all the people complaining start actually collecting some data.
Hello, everybody. Newb here (only have had the HTC Evo View 4G for a couple of days now). I have a question about the battery and screen. Is it regular for the screen to use up about ~60 percent of the battery? (According the usage stats). I find that the screen is bright, even on the lowest setting.
Also, I have a question about the battery. It seems to be draining a little quick (I am using lowest brightness and WiFi only). Could some people share how long their battery usually lasts for regular usage? I don't think it's a hardware issue. Like I've said, I've only had it for 2 days, so I don't know if I still need to wait a little.
Thanks!
The screen is one of the biggest battery drainers (if not the biggest) on tablets. So if you are using the tablet a lot, and the screen is on for long periods of time, then 60% seems normal. I don't have my Flyer with me right now to check what my % for screen is.
Battery drain is going to depend a bunch on how much you are using your View, and for what. With moderate usage, I can get around 2 days on a charge. I'd say that is about average for me. But if you are downloading big files and gaming, and/or have the screen on a lot, it can be significantly less.

Okay, that makes sense. The battery life seems to be getting better. One more question. I want WiFi to turn off after a certain amount of time once the screen timeouts. Is there any way to do this in the settings or with an app? The settings (official 3.2) has a WiFi timeout policy that gives three options:
Switch from WiFi to mobile data when screen is off
Never switch WiFi off
Never switch WiFi off when plugged in
I live in Canada and don't have a plan. Would using the first option drain more battery because it is looking for a connection? Or should I use the third option?
Thanks again.
Hmm, not sure. I have the WiFi only version of the Flyer, and on mine the first choice is just "When screen turns off". The first choice on your View is weird. Mobile data always uses more power than WiFi, if both are available. I don't see why you would ever want that.
BTW, I'm at home and have access to my Flyer now. Battery usage for screen is 52% for me. So I'd say 60% you mentioned is pretty normal.
You should also take into account, unless you've taken steps to turn it off/remove it, Cell standby might also be causing your battery life to take a hit. Since the View is set up to also be able to receive text messages, out of the box it's constantly trying to connect to Sprint's cellular network, even if you have mobile data turned off. This thread discusses ways to deal with it. Cell standby used to be one of the biggest users of my battery. Now, it's no longer a problem and I've seen a major increase in battery life.
As for the WiFi issue, the first choice in the settings actually says "When screen turns off (uses more mobile data)." That doesn't mean that it automatically switches mobile data on if you've turned it off in the settings by selecting that option. It's worded that way because the View is designed to be used on Sprint's network, so under normal circumstances it is assumed that if you turn WiFi off, you'll have a data plan and automatically connect to the mobile data network. If you don't have an account with mobile data from Sprint, and you've turned off mobile data in the settings, it won't be an issue because you have nothing to connect to.

Okay, thanks everybody. I really appreciate it. With heavy usage (basically using it all the time) I'd get about 6 hours and 10 minutes. Is that normal for everybody else?
Also, I have a couple of more questions, if you guys don't mind.
First of all, could rooting my device boost my battery life? Would it give me more access to settings like screen brightness?
And, do apps running in the background use battery life or are they 'frozen' until active? This sort of leads me into my next question. Is having 400-500MB of RAM always being used normal? Is the OS using all of it?
And I notice that when I put my tablet in airplane mode (to kill the 4G radio) I lose access to Bluetooth. Is this normal and will turning off airplane mode for a minute be a battery drain?
Thanks again, guys.

Answers:
Rooting won't necessarily boost battery life, but does give you ways to access more system items if you want using apps that take advantage of root.
Android attempts to keep non-rumming apps in memory so that it can load them faster in the future (Ram is much faster than SD memory). 80% Ram full is typical.
Airplane mode turns off all radios, BT, Wifi, GPS, 3g.
There are apps in the market that can turn various things on / off based on your environment / time / conditions

You don't need root access to adjust screen brightness. Settings -> Screen -> Brightness.

Airplane mode turns off all radios initially, but then you can turn almost all of them right back on (except for the cellular radios). I run mine in airplane mode all the time to keep the cellular radio completely inactive, but I still use WiFi, GPS, and Bluetooth when I need/want them, and they all work great. Are you running Gingerbread or Honeycomb? I do seem to remember some mentions of not being able to use Bluetooth in airplane mode on Gingerbread. It works perfectly fine on Honeycomb.
And you can turn off the 4G radio and all data service without turning on airplane mode (Settings -> Wireless & networks -> Mobile network). Doing this turns off all radios that receive data from the cellular network, but it doesn't turn all cellular functions off since the View is also set up to receive text messages. That's what airplane mode or any of these options address.
What I meant by adjusting the screen brightness was being able to control its range more than I can right now (I feel that even the lowest setting can be too much). But it seems that rooting/installing a custom ROM wouldn't do too much for the battery.
But my issue with airplane mode is that I can't turn on Bluetooth with it (Bluetooth is 'grayed out'). I am running official Honeycomb.

Did you try tapping on the box for Bluetooth in the settings even though it looks like you can't, and did you try using a widget to turn it on? I'm using stock OTA Honeycomb, and Bluetooth works perfectly fine for me while in airplane mode. I can turn it on in the settings (the box does look a little "grayed out," but you can still select it) or via a homescreen widget. If you can't turn it on with either of those, then it would seem that you've got some other type of problem. It works fine for me. I just tested it out again.

I just tried it. It seems to not be working for me, but it doesn't seem like a glitch but something built into the OS (I tried with a widget and it did a little 'no' animation). It's alright, I rarely use Bluetooth anyway.

I'd venture to say it's not something built into the OS. If it is built into the OS, then there's a glitch that allows me to use it under the same circumstances, and glitches rarely enable functionality. They almost always cause a device to lose functionality like you're experiencing. I'd be curious to know if anyone else is having the same issue you're having.
Last time I have ran battery test on my Flyer I ran it for almost 11 days on one charge. Yeap, 11 days. I mostly used Flyer as a notepad, checked orders on website couple of times a day, read emails. One day I played a game for about 20 minutes. At the end I set up and tested Plex and Google Music. I stopped the test at 11% charge. Overall screen was on for a bit over 4 hours (40%). Wi-fi on for 16 hours (only 4% ??) according to stats. That's pretty much it. Tablet idle 43%. Fairly light usage, but I mostly was testing how much of useable time I can get out of it. 11 days is a pleasing result.
Hi, I have a Samsung Galaxy A3(2017). This is an unattended phone with teamviewer host installed. I want to get to this phone at any times, but I seem to be unable to connect to phone after about 5-6 hours (or one night sleep).
I have tried install an app called HSPA+ tweaked and this fixes the problem, but it eats up my battery really fast. It sends ping request every 5 sec or so.
Is there any other way to keep my 3g/4g from going into sleep? I have tried different programs that stops phone from sleep, but mobile data (3g/4g) will still sleep after 5-6 hours unattended.
Please any help is appreciated.
Thanx

Seems able to keep a data connetion alive as you need, by using "Keep Alive" and "Reconnector".
Let us know if works.
EDIT: under the settings tab for "Keep Alive" you can also set the timeout for the ping command: by default is set to 5 seconds but you can increase this value.
This app did not work at all. Active keep alive is suppose to work, but it doesn't. It will stop sending ping quite fast. I tried to set it to ping every minute. After 15 minutes it stopped. No error in logs. active reconnect needs root access. I don't have that now. I tried to root, but I almost bricked my device.

Hi there,
I recently rooted my Google Pixel XL (8.1 Oreo) and have been working hard to optimise it much as possible.
I noticed in my battery stats that "Mobile Network Standby" has taken about 60% of the usage since my last charge so I thought I'd make a nifty Tasker script to toggle it on and off when needed. I've done a little programming in the past and have tried to write the commands as simply as possible in a way I can comprehend.
What I've come here for is to see if anyone would be kind enough to convert this into Tasker's syntax, or to perhaps give me some pointers on doing it myself.
I also have a question regarding what "Mobile Network Standby" refers to specifically. Would simply turning off Mobile Data fix this? Or would I need to go flight mode to fully disable it connecting to the towers? I've heard it's maintaining the connection that takes most of the battery, rather than the data itself.
So here's the code. The idea is that when I use my phone I always want an internet connection but also have the cellular off as often as possible. Wifi obviously takes priority, locking the phone for longer than 90 seconds turns off cellular, and after that it should turn on every 5 minutes for 15 seconds so I'm still getting Messenger notifications.
If (wifi connects) then
Turn off cellular
EndIf
If (wifi discons >15 secs) and (locked <90 secs) then
Turn on cellular
EndIf
If (screen turns off for >90 secs) then
Turn off cellular
EndIf
If (phone unlocks) and (no wifi) then
Turn on cellular
EndIf
If (not unlocked for 300 seconds) and (no wifi) then
Turn on cellular
Sleep (15 seconds)
Turn off cellular
EndIf
Thanks for your help guys, I really appreciate it!
