Hi,
I would like to know how much battery do the wi-fi, mobile network and gps options use if they're active but not being used: that is, if no application is making use of the gps, the phone is not connected to a wi-fi network and there is no network traffic at all.
Would it be worth bothering to turn those options off under these conditions? Or would it be a waste of time?
GPS 'should' be drawing little to no power if not requested by an app - in theory.
Mine is on all the time and my battery while not lasting as long as I'd quite like, is not being drained like it would if GPS was active.
I take the fact that as the GPS icon is not displayed in the status bar unless turned on by Maps or another app, that its sitting idle.
I 'think' having GPS on means that its available to be used by apps. If off , then its not available at all ever.
WiFi however is on regardless and will be sniffing for networks or attached to a network. Only off or asleep depending the sleep settings you've selected.
i.e off when screen off.
Would wifi use energy if you told it not to notify new spots?
According to BatteryStatus widget, my HTC Hero drops from 95% to 74% in exactly five hours of physical sleep (that's me who slept, not the machine, ok?), I turn the machine into Airplane Mode.
Darn, it forces me to bring the charger to work. (USB charging apparently doesn't do much)
I am not sure if it's the inaccuracy ofthe widget, or do some vampire drained the battery this fast. I have uninstalled NetCounter and Batter Status and Infodroid, disabled Peep update, bogged down Facebook/FLIckr updates to 4 hours, I will see if this machine can achieve longer battery duration tonight.
I'm kind of puzzled here. When my WiFi is turned on, I have a constant data transfer of about 20 Kbps (10 send, 10 receive), whilst if I switch on 3G, I have no data transfer (unless of course I'm browsing or whatever). Also, the WiFi drains about 10% battery / hour, which seems awfully lot to me. I have already tried to switch off all syncing, WiFi policy is set to never go to sleep. Any ideas?
Try "turn off when screen off". My wifi drains 1-3% depending on reception and amount of sync. Sometimes apps seem to hang when syncing and keep the phone awake more then they should thus draining more battery.

The point would be to have wifi always turned on, so that it notifies me when I get a new email.
Mine seems to be on although it is set to be off when the screen is off because I still get new mails or updates.

1. disable auto sync'ing on all apps such as email. I'd rather manually refresh when I use the particular app
2. Force Stop Google Maps from the Downloaded Apps list, not just stop it on the Running list. This stops Maps from restarting itself
3. Set wifi sleep policy to "Never when plugged in". All battery tips say to set wifi sleep policy to "Never". I don't think it's right for tablet. Let wifi sleep when not using it, unless you are downloading movies or tv shows then plug in the power.
The change is I used to recharge every other day, now I recharge every 3-4 days. Hope you get good results with my suggestions too.

thanks for the tip. another one is not to use auto brightness and try to keep brightness around 25% or less.
I actually froze maps with TiBu. I'll use it on my phone if I need it. It seemed to help a ton. Also, I turned ips+ on and turn brightness all the way down instead of leaving ips+ off and turning brightness up a little, I don't know if this actually helped battery or not but it kind of seemed to to me.

If I've helped you in any way... hit the "Thanks" button.
I find that not using my prime helps to preserve battery life..... C'mon guys, android is not a day old, and all these tips are more common sense nowadays than acquired knowledge. Meanwhile, I commend OP for trying to help.
OP, point no2, it depends wherever you allowed Google to use location at setup (you can change it in settings), you can shut it down all you like, but as soon as you use an app that needs location service is going to restart.

If your WiFi turns off when your tablet is sleeping, I don't think it is necessary to disable auto syncing of apps, since they won't sync without a data connection anyway.
Also I don't know what force stopping Google Maps is supposed to accomplish. Again if there is no data connection it isn't downloading or sending information it most likely isn't using any CPU.
The most important setting here is to disable WiFi when the tablet is sleeping. That is the only setting I have changed and I also get 3-4 days of battery life with moderate usage between charges.
How I cut down battery drain when I'm not using my TFP:
- Power it off

I don't have the option that says "never when plugged in". Mine says "only when plugged in".
I still get crazy good battery idle when undocked. I wont lose a percent for over 10 hours of standby. when it is docked I lose 1% every 2-3 hours. I've tried every setting but it still occurs

What standby setting are you using that you aren't losing anything in 10 hours???
I've been thinking about this for a while

Same here.
Which got me to thinking, and this is only my common sense here.
On standby it's clear why the dock's battery shouldn't be draining, but when in use the dock needs some sort of power to run. The trackpad needs power, the keys themselves need power, when you push capslock it has a light that turns on which also needs power.
It seems that using it's own battery instead of the tablet's for power consumption while in use is the right way to handle this, and that would also make sense for a higher battery drain when not is standby mode as apposed to standby mode.
Just some of my thoughts.
Sorry you are right. "Only when plugged in"

I've had my Z5C for about 10 days. I'm relatively happy with it, except for the battery life. Much worse than my old Z1C. Less than 24 hours of battery; my Z1C always got 24+. So, last night I tried the Stamina mode for the first time. Very UNIMPRESSED! I must be missing something.
1. In Stamina mode I still loss 15% of my charge in 7 hours.
2. With Stamina mode on it takes a couple minutes for my Wi-Fi to reconnect once I turn the screen on. Hardly usable.
What am I missing? Are any of you happy with the battery life? Does it improve over time? If you use Stamina mode, what are your settings and what is a typical battery discharge amount over an 8 hour period of non-use? Suggestions?
Thanks.
Im quite pleased with the battery life. 2-3 days with abt 4 hrs screen on time. I have disabled few services and applications from settings. There is a thread about it. Last night battery dropped only about 2%
For starters, disable location and untick "Scanning always available" under Wifi>Advanced Settings. Disable photo analyser service under All apps. Try these out first

Thanks for you reply. Some questions/points:
1. What am I losing if "Location" is off? For instance, GPS, weather?
2. Can you explain what "Scanning always available" does?
3. Couldn't find photo analyser service. Any thoughts?
4. I've removed set of widgets created with Zooper Widget Pro. I've read that it's a battery hog; any opinions?
5. I'm using an old weather app, BeWeather, because I like its widgets. I did notice that under "Location" BeWeather showed high battery use, while the Google apps listed showed low battery use. Any weather apps with widgets suggestions that might have low battery use?
Again, I appreciate your reply.

I might be wrong on some points, if this changed over the years, but...
1) If android/google isn't searching for location constantly, it will remember the last known location. So only your approximate location will be known, and apps that use it more specifically (like google fit, running apps etc.) will be less effective.
2) It means that your phone will connect to Google servers, even when Wifi is off. As far as I know.
3) It should be in your list with all apps. If it's not, I have no clue where else you should look.
5) I use "transparent clock & weather", and I never ask it to update his location constantly. Instead, I use a fixed location. Even when I'm 100km away from here, the weather will still be about the same, so for me that's enough.
Can't you look at the battery usage stats and disable anything that is near the top that you dont need?
I find the normal drain while using it is about the same as even my old phone. However standby is much much better. I used the phone sparingly and it lasted me about 2.5 days. On average, its lasting me about 2 days. On heavy usage days, I only get a day out of it. I havent had it very long so more testing is needed. There was only one instance where it drained really fast. I was in a plane on the ground. It seems that the reception is rather poor so it has to try alot harder to maintain a signal.

Thanks for your reply.
I looked at the power management stats. Oddly, the battery usage is:
Screen 34%
Cell standby 8%
Phone idle 6%
Android system 4%
Android OS 4%
Nothing else is listed. Under App Power Consumption it shows "Currently no apps to report". I don't feel that I'm a heavy user; minimal calls; minimal browser use; minimal texts. I have a weather widget with clock on both screens I've set up. The weather is set to update every 30 minutes. I've stopped using a couple widgets, as mentioned above, but I still don't see a significant improvement.
When you say "standby is much much better", are you talking about Stamina mode, or something else?
Thanks again.
Unless you use google maps, location doesn't matter all that much. Also if you need it in any app, you will be prompted to enable it. Once your work is done, you can turn it off again. Location actually does eat a considerable amount of battery.
About "scanning always available". It means that the phone will constantly be looking for wifi even if the wifi is turned off. This causes standby battery drain so it's good to leave it off.
I'm not sure about the widgets though as I haven't used them.
Lastly, photo analyser service should be in Settings>Apps>All Apps. Disable it to improve performance and battery life as reported by many users here and on talk.sonymobile.com
Cheers

Re: item 3. I had already disabled.
Any more suggestions? I turned on Stamina last night; still lost about 2% an hour. At the rate I now see (including using Stamina at night), I might get 36 hours of usage per charge, and I'm not a heavy user. Nowhere near some of the reports I've seen. I've turned off location, turned off weather updates for 6 hours of the night, turned off scanning always available in Wi-Fi, disabled photo analyzer, and removed widgets that seem to be "on" all the time. Additional questions:
1. I noticed that I have "Keep Wi-Fi on during sleep" set to always; is that OK, or do most of you have that off?
2. Are you all using the regular Stamina mode or the Ultra mode?
3. What is your setting for "Queue background data"?
That's it for now. But I expect to have more questions until I see the 2-3 day range you all talk about.
Thanks.

Try another night with Network mode set to gsm only. Just a thought
---------- Post added at 11:07 PM ---------- Previous post was at 10:53 PM ----------
I actually lose 0-1% overnight (in 8 hours on an average) on GSM only. I usually keep it on 2G. So basically my overnight battery drain is negligible. Also, I don't even use Stamina mode

Thanks for your reply. I've set the network to GSM Only. Seems to help a bit, but I'm still getting 2% battery drainage PER HOUR with Stamina ON! during the night. Again, looking at all the suggestions. The only one that I really use and would rather not disable is "Location". All of the apps under location show "Low battery use". I also prefer to have my screen brightness always around 90% (old age ). Can you tell me what widgets you have on your screens? I'm thinking I'll slowly delete each widget, if any of you think that'll help. I can live with 30+ hours of battery, but it's far from what I was expecting after reading the reviews. My Z1C had better battery duration.

I just have the walkman and clock widgets. Also, i switched wifi off before going to sleep or if it is switched on, i turn on stamina. Also, i have all sorts of sync disabled as i sync manually. My battery is nearly as good as that on Z3c (which is pretty amazing). Maybe some app is acting up on your part :/ I have nothing else to suggest man.

Might be my weather app. It's set to update every hour. I'll try turning off the wi-fi tonight. Last night I lost 11% in 8 hours. Acceptable, but not great. Maybe I'm looking for too much.

Not the weather app. It's set to not update from 11pm to 5am. Tried the location off, no improvement. WiFi was off using Stamina. Something else is going on that uses 2% an hour no matter what.

Aaaand I've run out of ideas. Try gsam batrery monitor from the playstore. Let it run through the night. That should give you an idea of the consuming apps
Thanks for your reply. I turned off my WiFi last night; only a 4% total loss. Tonight I'll try both the WiFi off and stamina, in addition to your battery monitor suggestion. Getting close! ?
Lost just 2% over 7 hours tonight! Stamina on. But I think my problems were all caused by my Bluetooth. I have 2 speakers on either end of my place that were always on. I also had my phone's BT always on. I noticed that at times both speakers showed being connected at the same time. I suspect that BT was constantly connecting and disconnecting as I moved through the apartment. I've turned off the BT on my phone. Battery life much improved. It's been 21 hours since my last charge and I'm still at 58%.
Thanks to all who responded.

Aah finally hahahah
It's a stock T-Mobile LG G5. I get around 2-2.5h SOT. Overnight it drops the battery by 8-11%. There are 34 screenshots in the ZIP file below, showing GSAM Battery monitor and BetterBatteryStats data. I've never used BetteryBatteryStats before so if someone could help me identify the culprit I'd greatly appreciate that.
The signal strength is excellent and the always-on display is disabled. The bluetooth and GPS are always enabled. I should mention that last week I put the phone in Airplane mode and the drain stopped, but obviously it's not a solution.
1.) why do you know, that the gsm signal is excellent? Because you can see 5 stripes in the notification bar? That is not real! I can see 5 stripes too, but this at 15 ASU.
But 100% signal is = 30 ASU! So this result can differ even you believe you can see 100 signal quality.
2.) my system is running on 20p. No BT and no Wlan (no NFC) with 8% for 24Std. (150 user apps installed)
3.) wifi and G-Mail polling sucks much battery power too! you should switch it of to compare! or is it real necessary to be on over the night???
4.) what’s about the google fitness app? this app needs power to check the sensors.
5.) Twitter; Google; G-Mail; Fotos are syncing many times! You can see together more then 800 wake ups!
no wonder that this together will suck your battery empty!
i would suggest you to switch off BT and W.Lan over the night! This should spend a lot of battery power too! Same for syncing and background data traffic.
Try to use 3C Battery Monitor app. there you can see the power consumption every 10 min in the night.
read this too! -> https://forum.xda-developers.com/showpost.php?p=74381087&postcount=327
I have 55 ASUs, so the connection is not the problem. Last night it only drained by 1%. I had both Bluetooth and GPS enabled so I don't think they are the problem either. Twitter, Gmail also were enabled and they actually pulled and displayed some notifications, yet the drain was minimal.
What I think sometimes happens is Google app or Play Services goes crazy starts waking up the phone for no reason. Would you agree based on the screenshots? Or could it be some bug in the OS that does this?
