Does enabling wifi when on standby drains battery, even if you're not connected?
I made some registry changes yesterday and I also enabled this with wifi, and I woke up with 20% less battery, normal for me is 7-10%.
I can't figure it out what I did wrong except if wifi is the problem?
yes if your wifi is on it will consume more battery. check if your mobile is constantly checking for new mails or updating the weather. disable them if you want your battery to last longer.

I would like to disagree completely. I've already ran rigorous test just to prove if it does or not on MY HD2. And let me tell you that it does not. YMMV.
It eats just as much battery as if you're using it but without the display on. So in any case, it eats less because the backlight remains off.
Using DsE V6.5 ROM. I got my battery to drain 3% every 12-15 minutes leaving Weather to update every 30 minutes and Send/Recieve new Mail every 5 minutes, Have pandora playing in the background and leaving web browsers opened, google maps activate.
During my test, I recorded the time and the % drop. I started at 9AM @100% and Dropped to around 3:30PM to 7% battery left. Now remember, this is a constant run without turning the device off, never turning wifi off and without exiting any windows. Also, Ive set my device to dim the screen after 1 minute and let it blackout after 2 minutes. Just take note that every time I picked up my phone to change a pandora station or read a new email, I never push the "end" key to let the screen go blank instantly. I let it do its full 2 minutes thing and let it go blank automatically.
This is just so I remain very rigorous!
This has helped me understand a lot about my battery and how much I can pull it out during a full days or usage.
I noticed that My battery can last up to 6.5 hours of basically, NON-STOP usage. Just image if I turned off wifi and only needed it the moment I wanted to check if i had new mail, etc. My battery would last ALL DAY.
FYI, under normal use, my battery is around 55-65% by the end of the day under moderate use.
I have updates every 6 hours for weather, but I can see it connects to 3g when is the time. This is not the problem.
The problem started yesterday/today when I made some registry changes...I enabled 24bpp colors and I turned vsinc off.
I am not connected to wlan, it is turned off, I only enabled the option "enable when in standby" if I sometimes need it when phone goes in stand by.
I am asking...does enabling ENABLE WIFI IN STAND BY eats battery when NOT USING WLAN AT ALL?
Thanks
For some reason no matter what build, radio or rom I use BatteryMinder tells me that I will get better life with wifi on vs wifi being off. (check jpegs in attachment)
If i turn mobile data off too I get better battery life as well.
Why is the Mobile network killing my battery?
I would guess this has something to do with 3G that gets disabled on WIFI start
Yea I figured that how do I fix it though?
I stop using batteryminder because the time fluctuation was killing me! one minute it would show 1 day of battery left after unplugin, and 5 minutes later would show 15 hrs left, but only 2% had dropped in the battery, I guess it reads everything that's running, and takes it into consideration to tell you what time you have left. I get like 3 to 5mA at idle so I don't need it anymore to tell me how much battery I have left, I get a full day of battery.

This is a known fact, the wifi radio uses alot less power transmitting data than the 3G radio. I have about 20 Wifi access points stored in my phone so that it connects to them automatically like Home, work, church, parents house, friends house, that way the only time I'm actually using cell data is when I'm in the car. Saves the battery a ton.
If you want to use 3G all the time, but save battery, turn off always on data in the settings and set it to sync on an interval instead.

Odd, when I enable WiFi and set it to never sleep (so it keeps WiFi on when screen off instead of reverting to data), I idle at 10 times higher mA than with WiFi off. When actively using the connection (browsing, etc) it does seem less energy consuming than data, though.

Same here. Idle goes up to 70mA with no sleep.
I set it to "never when plugged in" and it seems to work fine.
I'm in desperate need of a combo so I'm trying yours as we speak

This is all excellent advice. Cheers roloracer! I use similar settings and software for the most part with Core Droid HD v.02 by Sergio76 right now, and the standby drain with WiFi and GPS on, auto background data sync off, sits much of the time at 7 mAh. This is without using SetCPU. Moreover, with WiFi and GPS off, the standby drain drops down to about 5 mAh on average. This is about the same as I get using EVO Black & Blue Remix v.03A with everything off as well. That said, both of the above mentioned builds are incredible, IMHO, and both include the hastarin r8.5.1 Kernel.
Best to all,
R
If you are in an area with spotty coverage, and constantly switch between 2g, 3g, H, etc... then it supposedly runs your batt down a lot more than in steady coverage.

How much mAh do you have when you use your phone and how much
When It's in standby??
I got 3-6 mAh in Standby and 110-400 when using the phone (500mah when using the camera)
With this info my phone only last around 10-13 hrs

10 to 13 hours of heavy usage is not bad, light use is a different story, even on windows mobile with heavy usage you can see about the same 10 to 13 hrs of battery, My phone averages about the same as you, at idle with the screen off is about 3 to 7mA , with the screen on but nothing extra running about 120mA, and with stuff in the background about 250mA, or with the camera is about 400 to 500mA. The key is to always check advanced task killer, kill all before turning off the screen, I use my phone lightly to medium during my work hours, I text a few times, facebook a few times, some phone calls, but during all this time I keep my background sync data off, I only turn it on if I have to go into the market, and I turn it back off after I finish in the market, then when I get off work, like 13 hrs after I unplugged from charger, I usually still have about 50% to 60% battery, I flip on the background data and go full blast on it, til the end of the day.
I am really new to android devices.
I got a Rogers moto flipout MB511 (Canada) from my friend recently. The standby time is terribly short. Discharged within 10 hours just standby in an area with good signal strength (-69db, 2G only).
I have disabled background sync, wifi, 3G, used setcpu to use 125/125mhz when screen off, removed facebook account. (I do have gmail account setup) The standby could be even shorter if I don't do things mentioned above.
Tried different roms, like 0.18.4 (This is en.CN rom), U3_01.14.2 (This is a rom without Motoblur, is really fast!), no noticeable improvement. With Powertutor, I haven't found any suspect app consuming too much battery power.
I was expecting at least 2-3 days with phone standby in 2G.
Does anyone have the same issue with me. i am wondering if this is hardware related issue or software issue. I suspect this phone might have current leaking issue. Is there any software can accurately report current?
Any suggestions?
That also arrives at me that do I have to make?
the same trouble to me
I'm guessing it's just a standard effect of how the phone draws power. The guy i bought mine from on eBay included an extra battery with it, for that reason.
But this is definitely abnormal.
Using *#*#4636#*#*, I found the there is some problem with Android system, which holds partial wake lock most of the time. So the phone is not in sleeping state for most of the time.
I don't have data to prove this. I know some of the guys' flipout can last 2-3 days, and they all have data plan (not just something like unlimited browsing, with only 80 port available.). For some of the reasons, I feel this is caused by Moto blur. A lot of blur stuff is put into android system. They might try to communicate with the blur server, which requires SSL and 80 port available. Because my phone doesn't have data plan, communication will fail. During retry, the blur keeps partial wake lock and prevent phone from sleeping.
I got this issue with all firmwares that runs on my phone, including the deblur version. I think even the deblur version has a lot of blur stuff and try to pass back some user data back to moto server based on IMEI.
Try buying a new oem stock battery?
I am pretty sure it is not the fault of the battery. I have 2 stock batteries, standby time is proportional to their capacity.
The issue is obviously the partial lock.
Same here
Battery goes pretty fast even when not using the phone, even worse when using it.
Yeah I'm also experiencing same problems! I'm using the deblur version.
Battery drains like hell! I'm also on 2G, no wifi, no gps, no data sync!
I've checked my battery usage and this is what I got:
Voice calls: 32%
Cell standby: 22%
Phone idle: 18%
Android OS: 16%
Android System: 4%
ZDbox: 3%
Display: 2%
Cell standby, Phone idle and Android OS seem to be quite high. Anyone know why?
Thanks
Hi,
Same sh*t here...
I have better results if I am running the JuiceDefender (extreme profile: data on demand) and SetCPU (profile: on screen off: 125/125) . Note that on the SetCPU the profile options (on the top of the profiles) MUST be checked in order to be active... Unfortunatelly I am stuck to 3G only (feckin three-mobile-UK does not allow to fallback to 2G)
Also, I am running the "Quick Settings" in order to cut off quickly the GPS/data/wifi.
BTW, be sure that the Settings -> Data Manager -> Data Delivery -> Blur Applications is set to "Sync over Wi-Fi Only"
My results so far are :
mobile left the overnight charger arounf 7:30, then after 12hrs (19:00) the battery is around 60% .. all this time just some sms (no calls at all) plus around 10min email check..
cheers

three uk are a 3g only network they have no 2g system
all of their handsets have been 3g from the start because of video calling
I´ve got 24h+ Standby time, Deblur + Juice defender + Never make/recive calls with this ****.
i had the same problem. only 6/7 hours tops with juice defender on!
i switched of 3g and now it does 20 percent a day!
must be a firmware issue.
i got deblurred rom, euro.
with rom deblur,setcpu with screenoff freq 125-250 (screenon 125-550mhz),juicedefender free (set screenoff no data,app update freq 30min),10 sms received,15 mins of call,internet navigation about 10min,my flipout is now at 50% of battery (the phone is on by 9.00AM)...
but with this setting and with a more intensive use (20-30 mins of call,10-15 sms,30-40 mins of internet) my flipout goes at 0% in about 12h
Hi,
Its almost 2 months after my last reply here..
My flipout now can stay 48h on standby, and on normal usage (around 50 sms send/receive and 30min of 3g data..) can be stay alive for 1.5 days ..
The applications that I find very usefull are:
SetCPU (I set the phone to be 125Mhz min/max when the Screen is OFF)
DataSwitch ( to kill any data connection)
Autorun manager (to avoid running some apps like Skype)
I also re-calibrated the battery a couple of times (I left it to be completely drained then recharged to 100% and used a util called Battery calibration)
Not bad anyway...
cheers
i want to know... is it better to turn off wifi when screen turns off or 3g consumes more battery than wifi.
i think 3g consumes more battery than wifi, i don't know why every one recommend to turn off wifi when screen turns off.
Additionally, the process of switching on/off wifi/3g will consume more battery...
Turn all data connections OFF when not using them.... this will save battery.
you can use wifi sleep policy, but if you are on GB you may experience Android OS drain...
turn off all data and set wifi sleep policy to never

WIFI OFF when not using - most of its idle state consumes up to 10x juice as data connection at idle (15-50 mA / 5 min)
DATA CONNECTION can be ON <- at conected but idle state it is not using more juice then if that would be off (5 mA / 5 min)
as well as BT and GPS can be ON all the time
ofc itt will not be so low if youll have sync every minute or some live widgets
Get juice defender, set it up right, and you will see a big gain!

there is no need for any juice or battery defenders
any task/proces killers/managers or any paid or free apps
that are said to make your battery life better longer better whatever
basicly stay away for wifi and remember when you play games, use gps or simply use the phone battery will go down.

How did you gather this data?
I want to do some testing
battery monitor widget gives you such data and many cfg options
that is data given by diff phone codes gathered in one place, presented in configurable graphs and more...
damn i sound like commercial =)
this 5mA in idle is due 5 background apps (all sort of monitors i run)
think with a clean system it could be 1-2mA -that means-> basicly no % loss when you are sleeping and phone is not used
now i have few % loss by night but i find that more then ok
In my opinion you have definetly turn off ur wifi if not in use. It'll drain your battery!

nice thanks^^
3G use more battery then WIFI does
jvp - idle - no
i leave always wifi off do not make sense to keep it on since it will be scanning the hole time for new network (which mean more battery wasted) .
Also when i leave my wifi on sometime the phone connect to some near network , which require some http identification , so the phone will be connected to wifi network but without internet , in this case email sync and other auto update stuff will not work until i get away .
SO here when needed and there is a wifi network available i just switch it on .
iget searching->connecting->disconect
on my MIUI galaxy, there is a fix for that?
This isn't a thread for when your battery drain is excessive on standby, this is a thread dedicated to figuring out how to simply get more power to the phone for extended runtime.
I'm using a 5000 mah external battery pack for extra charge, and it seems to be good enough to last me at least an extra day or two of usage, which is great. It seems like the only other options are cutting up the battery door to fit an extended battery from the evo 3D or just carrying extra batteries...
Best easy change for me was always using wifi instead of the network when at home and work. Made a huge improvement

So....how to get the most time out of your battery in standby?
As you've allready said:
One of the biggest improvements is possible by using a Sensation or Evo3D battery. With that i get a nice 1% per hour in standby. (It's actually a bit lower than 1%).
While not using the phone it's unnessecary to have 3G activated. Recieving emails and texts via whatsapp, viber etc via 2G is good enough. For everything that is more datahungry you can allways activate 3G manually.
Keep background data turned off. I use K9 Mail which works independently and Whatsapp recieves messages too. But a lot of other stuff doesn't syncronize which means less wakelocks and thus less power consumption.
Same with locations. As long as you don't WANT to tell google your every step you can keep network based location turned off.
If you need a location fix quickly you can allways turn on gps for a moment. After using the FasterFix app (i guess you need root for that), i get a gps lock in 5 seconds, so i can determin my location really fast and share it with others (for intance via whatsapp) without having to keep it on all the time.
And last but not least:
You probably don't need to know the current outside temperature every 5 minutes. So set that to manual update too.
Doing these things doesn't turn my smartphone into an overweight dumbphone with a battery problem and i get a maximum of over 4 days of standby time out of it.
Normally my battery holds for roughly 35 hours (1 day and 11 hours), but it's usually awake for 1/4th of the time serving as my newspaper and video and mp3 player.
/edit:
Totally forgot:
Use llama!
You'll never have to worry about forgetting to set your phone on vibrate while at work and setting it to loud at home.
You can configure it so it only activates wifi at home and turns it off again if you didn't connect to any access point after a set amount of time. I haven't had to activate/deactivate wifi manually for ages without having to worry about it constantly searching for networks and sucking my battery dry!

Exactly what he said, but you can automate a lot of it by using an app called Tasker. I use it to sync all data on my phone for 3 minutes every 4 hours so it's always up to date. It can also automate the GPS on/off depending which app I use so it switches on when I open CoPilot and turns off again when I close it.
Tasker can also replace Llama if you can find 'profiles. to do it. Llama looks pretty good though.
I think the biggest drain is the display. With auto brightness on, the sensor will monitor the changes in your surrounding every second the moment you turn on the screen. Turn that off and manually control the brightness save a lot of battery.
Or just use lower autobrightness script.
I use Invisibright. Long hold on search softkey + slide enables me to set the brightness to whatever I want in a second no matter what apps are running.

It is still useless as your sensor is still working every time you turn on your screen. The sensor is draining your battery. Not the brightness value.
Autobrightness sensor drain
So you think that there is a greater drain from the light sensor than from an uncontrolled screen brightness?
Interesting thought. I'll manually set my brightness level a round20% for the next charge cycle and see what effect it has, though I suspect that as my display currently accounts for 20% of battery drain it won't make all that much difference.
I use juice defender and I think its actually working.
