Q1: How often do you reboot your phone? If you enable 4g and disable it do you reboot because of the bug where it still trys to connect?
Q2: If I'm home with good wifi is it better on the battery to have wifi enabled or disabled on the phone?
I have found it that if you are in a bad reception area wifi seems to save my battery life by about 35% rather than running 3g.

Was wondering for android devices if having wifi on is best for the power.. as phones use power trying to find better signals. I have a wifi, and a good signal at my house, what should i use?
And also for battery life, when i hold the off button, there is an option to turn Data network on/off, if i turn it off, do i save power? Thanks!
Also.. is it bad for my phone if i swap between 2 batteries that have different levels of power on the at the time? like 40% and 90%? Thanks!
If you're at home with WiFi then turn it on and kill mobile data. WiFi can save more juice even if you don't necessarily have poor reception at your house. Your voice is still active. It's not like airplane which kills all the radios. But you can do that as well and still connect to WiFi.
As for the battery switching, I don't see why that would be an issue.

When out of range of Wifi, turn Wifi off, When in range turn it on for best battery life
There's an app called WiFi Status that I use. When you go out of a wifi range, it notifies you to remind you to turn off wifi. Saves a lot of battery, as wifi isn't constantly scanning.
I think it's justified to make it stay on for smartphones. And my Atrix's battery life sucks. Irony is - it seems to be the best smartphone battery (for an Android device, yet).
And honestly, smartphones' battery benchmark tests should only be done with Wi-Fi turned on..
I use an app called Y5 https://market.android.com/details?id=pl.polidea.y5&feature=search_result. The app can record your wifi zone, and will disable wifi when out of range, and re-enable when in range. It saves me time and energy when I get home from work.
use wifi at home.
Yes turn on wifi only when needed.
Hello everyone i am currently running sacs sense 3.0 rom which to me is the most stable with v6 supercharge script
Ive changed my kernal to chopsuey 9.1 with the bfs,uv,.. etc
Im gettin decent battery life but i know it can do better
Now ive had other roms where 3g disapears when phone is in standby and when you turn screen back on 3g comes back. I would love to have that on my phone
Does anyone know how to get it or put it?
I think that would make my battery life be even better
Also anyone know why my display would be at 50% using battery when i check whats using my battery if
My brightness is at 18%
The 3g on and off when you turn off the screen is a app Its called juice defender

You can also uncheck always-on mobile network under the wireless networks settings under mobile network.
Thanks for the replies
I will try juice defender...
I will also try to uncheck that setting
But is their a dofferent way to make the 3g not be in use when in standby
Or is it coocked in roms when they make them..
Hi All:
I am experiencing tons of wakeups by com.android.phone regardless of 3G or LTE which drains my battery 6%+ per hour. However, if I have wifi, the drain drops to minimal. I turned off Fast Dormancy already, Any suggestion or fix?
Regards,
Frank

Which stock ICS are you running? Do you have wind kernel installed? Download and run better battery stats to see what wake locks you have. In regards to Fast Dormancy disabling it will either give you better or worse battery life. What is it? Its a tech used by the phone company to save battery power by putting the phone's radio in a low power state yet never relinquishing the data connection, so when you wake up your phone it doesn't have to spend the 3-5 sec reestablishing the data connection. The phone's software works hand in hand with this, however if your phone co in your area doesn't support it the phone's software will never let it sleep, therefore disabling fast dormancy will improve battery life. However if you have it disabled and your area supports it your data connection will never be released and therefore your phone's radio will never be shut off using battery. On top of that this is only a function of an HSPA/3G coverage area. With 2g (edge) or LTE its meaningless. Two more suggestions:
1. Power off the phone and remove the battery for 30 sec - 1 min. Then reassemble and power back on. For some reason this will fix the deep sleep suspend wake lock.
2. If you are rooted and have cwm installed, boot your phone into recovery. Create a backup. Reformat the system and data partitions. Reinstall your ROM, then go to restore/backup and select advanced restore. Select data then the backup just done. After complete reboot.
Good luck.

Thanks for the response. From BBS, the main wakelock is alarm com.android.phone, over 700 in an hour. I am using Vodafone V20c with Wind 3.4. Will try the battery removal and reformat trick.

Unfortunately No. Battery still drains 7%+ per hour on mobile network. On wifi, it's 1%. I have turn on Fast Dormancy just for the sake of it. Maybe need to move to CM 10.1. However, I play games on the phone sometimes and enjoy the snappy response of ICS.
I've been having problems with battery drain, from 6-7% an hour to more than 15% with the latest CM RC.
Changed over to Pac Rom, seems to be a lot better for battery power so far but a bit laggy.

A couple more things to try:
Wind kernel 3.6
Disable syncing.
Make sure you are not using LG supplied weather app widget bad power hog.
If disabling Sync works but you still need to get things like email notifications try using DS battery saver from the play store.

I will try Wind 3.6 and had tried Juice Defender and DS Battery Saver, but with 4G, the phone cannot go into deep sleep. It keeps searching for network, hence the wakelocks. I doubt Wind 3.6 can resolve the issue. Anyway I can use a different com.android.phone?

Try this:
Settings
Wireless & Network: Select MORE
Select MOBILE NETWORK
Select NETWORK MODE
Select GSM/WCDMA Auto
This will turn LTE off and should fix you issue, in most instances HSPA+ (4G on AT&T) download speeds are just as fast as LTE without the power issues.

I am having screen frozen issues with Wind 3.6, so have to revert back to 3.4 The disabling of LTE does not help the com.android.phone wakelocks. To summarize, my P936 cannot go into deep sleep while on Mobile Data regardless of LTE or 3G. I turned off sync and wechat app, but leave gmail and whatsapp in the background. Any more suggestion?

In the past I had issues with the whatsapp creating wake locks. Now this goes back to last year but I stopped using that app because of those issues. Try freezing it and reboot. Also when is the last time you calibrated your battery? Just in case you don't know: charge to 100%, while still plugged in reboot into recovery and wipe battery stats, then reboot your phone and unplug. Keep your phone off the charger till the battery goes dead and the phone powers down on its own. Then charge to 100% with the phone off. Also I think I asked this before which version of v20 are you running?

Anybody else getting battery drain from wifi calling being enabled?
My wifi calling is on but when i go into power saving settings the WFC Setting is not there to show if it is draining battery.

It should be draining your battery. You are constantly broadcasting a wifi signal looking for other wifi signals. I turn off wifi period unless I am at a location I want it to be used at. The Wifi is the strongest RF generator on your phone and the one that creates the most drain next to the display.
It should definitely NOT drain your battery like that. Not even close. I use it all the time. You need to clear out the cache and clear data if possible. Force stop the app and reboot. Should be good to go.
I turn on the wifi calling at work, lowest I have seen my phone go to is about 50% at a 9 hour work day. Have no issues with battery life on wifi calling.

More ZF2 battery usage weirdness... Wi-Fi is among biggest consumer, even when I've had Wi-Fi turned OFF the whole time! Also at the top are usually Android OS and Android System. Hopefully the Wi-Fi use is just being miscalculated. Or can really be eating the battery? Can other ZF2 users confirm/deny this weird usage?
Attached pics are from when Wi-Fi had not been turned on the whole time.

thats totally opposite from mine...mine highest is o.s drain...even my wifi always on 24 /7.. yea yours weird
Mine too
My wifi drained my battery pretty quick yesterday too, I only turned it on to download some apps, but it still kept killing the battery long after it was off. Who knows maybe it's only a problem for those who toggle wifi as the other guy said he leaves his on 24/7
I think this is the old 5.0 wifi bug we saw on the nexus 5, back when it lollipop was released.
I have unlimited data so I just turned off wifi and rebooted the phone, battery life seems much better since I did that.
Unfortunately I know that's not possible for everyone, you could also try turning off background wifi scanning in advanced wifi settings.

Thanks, I'll try turning off Wi-Fi scanning. The most recent release also seems to have improved battery life.
