Guys, don't ask me to search again... i really did... and didn't found any answer....
i am new on android.... and it's regarding the battery's life time...
i hope someone give me an answer here....
there're a lot android user saying about advanced task manager, juicedefender, v6 supercharger, cell standby, phone idle.... anyway... i got no answer at all....
few people using ATaskMan and improve their battery life, but few people said it just drain my battery... anyway...i don't see any improvement using that....
i used juice defender to keep the connectivity.... better than keep it all the time...
didn't see any improvement also....
i used setCpu too... keep it low at night.... i don't really know if it works....
all i want is keeping the data on as long as possible.... even on sleep.... to keep apps like viber, whatsapp, im+ and sometime to sync the apps like weather, facebook, twitter and email...
weather, facebook, twitter and email... these apps were set to manual... not automatic....
i don't call and messaging a lot.... just stay on in internet...
i don't play games a lot... maybe few minutes....
so my questions here...
1. did the apps on background really drain up the battery? because they are, who using v6 supercharger didn't have a problem with battery.... and it's not like ATaskMan... it's didn't kill the apps at all.... just manage the background apps...
2. did the widget also drain the battery? some people said so....
3. keep the data on all the time? i read in this forum... they keep their data on.... but, still having their phone more than a day... moveover... some guys get it over 2 till 4 days...
if it's about ROM, it should be same with other, who uses the same ROM...
and if it's about hardware... it should be from the first time i bought this phone....
i just want keep my phone as long as possible with data on.....
anyway.... i still keep tracking what drain my battery the most....
hope someone come with answer for this....
and sorry for my english.....
1. That depends on which apps are running in the background, but when your device is in standby it should go to "sleep", but if you've set some apps to update every 15 minutes, the phone will wake up (without turning the screen on of course) to update them. This will naturally use some battery. And remember that Android can handle all processes itself. You don't need to kill them yourself. That will actually decrease batterylife since the phone has to start the apps again everytime you kill them. A task manager is nice to have if an app is going rogue.
2. Widgets do use battery, and the widgets who are set to automatically update itself uses more battery (Facebook, Twitter, Weather etc.)
3. "This tip is one that seems counter-intuitive, but you can save a lot of wear and tear on your Android phone's battery if you tell it to keep the Wifi radio turned on and connected while the phone is sleeping. Your phone needs a lot of juice to keep pinging those cell towers, and even more to transmit data to and from them. Wifi radios use much less power because of their design, and they don't have to keep searching for a better access point. It's the way cellular data communication was designed, and it's a necessary evil.
But what if you're spending all day (or all evening) in one place, connected to Wifi? If you tell your phone to shut off Wifi when idle, it bounces back to cellular data (be it 2G, 3G, or 4G) and starts sucking down the electrons again when the screen shuts off. That's no good, and easy to fix:
Open the advanced Wifi settings by pressing the menu button, then Settings, Wireless & networks, Wi-Fi settings, and tapping the menu button again. You'll have a choice to either Scan, or go Advanced -- go Advanced.
Tap the Wi-Fi sleep policy entry, and you'll get a pop up dialog with the choices you see in the picture above. Choose Never.
Now even when your phone goes into standby mode, you'll stay connected to Wifi and be able to get mail and messages without turning the cell radio back on and trouncing your battery life. And for the times when you're not in an area with a Wifi connection, just shut Wifi off, either through the menu or with a handy toggle widget. Your battery will thank you for it."

The android OS has a built in task manger so using ATK or ATM is actually worse than if you don't.
But honestly rooting has made all of the difference. If you have time for it READ about what it means to root and the how-to's, youtube instrutional videos, etc.... just get your feet wet a lil bit. When/if you feel like it is something that you might be interested in, go ahead and do it. You wont regret it and you will diffidently be able to improve battery life with titanium backup which allows you to freeze apps that you dont need running.
Warning 1) you might become addicted to flashing ROMS... and 2) if you screw up your phone you can't blame anyone but yourself.

at least for my phone: regarding setcpu, you can raise the minimum frequency, increasing performance while hardly affecting battery life (at stock i had 245/600; now i have 480/600). turns out that if you set the minimum frequency low, it will take some juice to ramp the cpu back up
just a little tip
Just wanted to add: besides titanium backup, I'd also recommend gemini app manager and better battery stats. You can use gemini to edit an app's autorun permissions (ie, automatically starting at boot) for those apps you don't, can't or shouldn't uninstall/freeze. If you're having issues with your phone not sleeping better battery stats will help you identify what's keeping your phone awake.
Lastly, there is only so much you can do to optimize your battery life. In the end you're going to have to sacrifice some functionality for better battery life or vice versa. You just need to find the right balance you can live with.
What is the longest running time did you had on your phone? I reckon batteries are getting thinner and thinner and will not last long.
Apps are there to help you avoid manual work. If you switch of automation on all the apps then you will have to spent time and do it all manually and on the other hand how much life will you save lets say %15. Not worth it!
Best solution is to stick your handset to the charger while you are going to sleep!

i set it 300/300 at night... it's from 00.00 til 06.00 which i don't touch it.... i don't know, if it is a good idea.... i guess, background apps wouldn't using cpu so badly.... would it?

im trying tasker right now... 15% fair enough for me.... without losing data....
i am almost 12 hours out there every day.... i wanna figure out, how to spare the battery life... cause i wanna buy tablet.... which consume more battery than a phone....
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.
Thanks for all of your help (plus everybody else, too)!

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.
Hello to all and thanks for your time.
First of all i did search about such a thread and could not find any which seemed to help including the stickies.
My problem is something on my room is misbehaving and chews trough the battery like hell.i need help identifying it.
To id my system :I'm on 9100xxlpw stock rooted no additional battery managers.
to describe the problem. I charged the phone to 100% and 5 hours later it was 50%.(i was sleeping so they're was no usage)
CPU spy reports 30 min of deep sleep rest 200mghz.
I'll add battery stats later.but basically Android system is chewing the batt. System appears to sleep but doesn't go deep sleep

Added Screen shots, please ignore media player and usb. I took screen shots as soon as I notice strange stuff but somehow system showed the screen shots duplicated so I deleted duplicates. Later I noticed I deleted the originals (most probably there was one c to begin with but gallery showed me duplicates, which is strange ).
New ones are taken after apprx. 1 hour of XDA browsing & listening to music.

I think I have a possible culprit while searching for suspend_backoff
I found this http://forum.xda-developers.com/showthread.php?t=1697899 the phone model is different but I decided to turn wifi off to test and my battery consumption is almost like flat line when I'm not using the phone now (Data & synch is still enabled ). I do not know what causes this but I am not trough yet. I'd appreciate anyone to ID the source of the problem and how to overcome it (other than keeping wifi off) or should I switch to another rom
I have the same problem as you, but I think it is related to the (known and not yet solved) problem of the "dirty WiFi network", as it happens only with my office WiFi and not with my home one...
However in my case the problem is intermittent, while I always have the same high drain under the office WiFi, the major source of drainage changes, sometimes is suspend_backoff, other times it's deleted_wake_locks...

I also had a feeling it might be wifi. I'm not sure what you mean by dirty wifi but. My home network seems to be suffering from dns problems. Also when I go to work one of my customers has a proxy while other has a unprotected wifi with web login. in both cases phone is able to connect to wifi but not to internet.
I also considered this might create some drain but it is too severe. I even thought my phone battery to be dead.
My Galaxy S3 Battery Life Sucks Please Help! 15% After Only 7 Hours.
I’ve been having this same problem sense I got my phone about 2 months ago but now I’m finally just tired of it! My phone is rooted, using the stock ROM.
What I do to help battery life:
- Every morning I hold the home button and kill multitasking and kill all running aps in the background then I open autokill which automatically kills running apps in the background that are not needed.
- I have power saving enabled
- Easy Battery Saver running
After 7 hours of use I’m already at 15% and through out the day I barley use my phone. Its like this just about everyday. I use my phone about an hour of the entire day of web surfing and Facebook usage etc. The rest of the day I’m only texting and maybe taking 3 or 4 phone calls that last 10 mins. How much battery could that possibly take? A flip phone can do that and last 3 days..
I used my iPhone 4S much more during the day then I do the galaxy S3 because the S3 has terrible battery life.
On my iPhone I would have about 22% after everyday of using it for 11 hours down time = sleep and 4 hours of usage = texting, , phone calls, web surfing, games etc.
I don’t play games or watch movies on my S3. Only texting, instagram, facebook, websurfing which is about an hour a day usage. Also a couple minutes of GPS usage on some days.
What can I do to fix this? I don’t want a bigger battery that will make my phone any thicker.
I have pictures below showing usage through out the day and usage under battery.
Please help!
Thanks!

Oh thats easy.
You're phone is always "Awake". It doesn't go into Deep sleep like everyone elses. If you take a look at the first picture you linked with the graph, it shows that the phone is always AWAKE.
For comparison, I have attached mine as a reference but something is DEFINITELY keeping your phone awake.

Can't really see anything that stands out per say...
If you see anything on that thread or any apps on your phone that you think could be keeping it awake, just uninstall them. I would suggest trying to remove them a few at a time just to narrow down which ones are keeping the phone awake.
Also, apparently this app helps a lot (https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy) and Better Battery stats should give you a better idea of which apps use the CPU while your phone is trying to sleep.
Oh and remove any task managers you have installed.. Those tend to be the worst offenders.
One last thing, found this on another forum:
- Don't use an automatic task killer--not even the one that comes with the phone. Reboot your phone and look at what's running. If anything that you've installed is running and there's no reason for it, then uninstall it and find an alternative that behaves. Ignore any stock apps that run on boot as I've found them to be more or less benign.
- Weather widgets, live wallpapers, news/social feeds, any app or service that you use that runs--do without it if you can. If you can’t do without it, lengthen it’s refresh time.
- Don't use antivirus
- Set your WIFI sleep policy to never. The default is "turn off when screen turns off". This will cause the wifi to reconnect every time you open the phone. From any Home Screen select Menu/Settings/Wireless & Networks/ and then use the Menu button to see some new options - select Advanced. Then select Wifi Sleep Policy and set it to Never. Home key to return to Home Screen.
- If you have access to wifi, leave it toggled on as it is more efficient than 3G. Wifi consumes less battery power than 3G.
- I leave GPS toggled on too by the way. Apps use it as needed. When I'm done with Maps or an app that uses it, I'm sure to return to the home screen so GPS can stop. Under wireless settings turn on "Google location services" so that an app is able to use network resources to get your location instead of GPS. I have "VZW location services" turned off--don't know why that option is even there. By the way, I increase the speed of voice output > text to speech > speech rate because I like the directions to get spit out faster. That saves a bit of battery. Turning off the display and just listening for directions help. Also, often I just get the directions and then exit back to the home screen: GPS uses so much battery I try to get it over with ASAP.
- Under Accounts, click on any account listed and turn off sync for any items that you're not interested in syncing. For example, Google Books if you don't use it. Don't use Backup Assistant--I prefer syncing my contacts with Google. You don't need both. Also go into your contacts > menu > display options > backup assistant > UNCHECK. Also do contacts > menu > more > settings > contact storage > and select your Google account and "remember this choice"
Are you on the 3G network a lot or weak signal areas? Is your phone hot around the bottom? If yes to both, most likely it's because of the system attempting to find a better signal. When I was swapping out my SIMs, in various countries, I only have 3G network and my battery fully drains in 7hrs at idle. The only way i can go a whole day is to place my phone into airplane mode or wifi only to conserve the battery.
my battery runs at-most 13 hrs........................

My Galaxy S3 Battery Life Sucks Please Help! 15% After Only 7 Hours.
I’ve been having this same problem sense I got my phone about 2 months ago but now I’m finally just tired of it! My phone is rooted, using the stock ROM.
What I do to help battery life:
- Every morning I hold the home button and kill multitasking and kill all running aps in the background then I open autokill which automatically kills running apps in the background that are not needed.
- I have power saving enabled
- Easy Battery Saver running
After 7 hours of use I’m already at 15% and through out the day I barley use my phone. Its like this just about everyday. I use my phone about an hour of the entire day of web surfing and Facebook usage etc. The rest of the day I’m only texting and maybe taking 3 or 4 phone calls that last 10 mins. How much battery could that possibly take? A flip phone can do that and last 3 days..
I used my iPhone 4S much more during the day then I do the galaxy S3 because the S3 has terrible battery life.
On my iPhone I would have about 22% after everyday of using it for 11 hours down time = sleep and 4 hours of usage = texting, , phone calls, web surfing, games etc.
I don’t play games or watch movies on my S3. Only texting, instagram, facebook, websurfing which is about an hour a day usage. Also a couple minutes of GPS usage on some days.
What can I do to fix this? I don’t want a bigger battery that will make my phone any thicker.
I have pictures below showing usage through out the day and usage under battery.
Please help!
Thanks!

Welcome to smartphones. The calls alone will drain the battery. Seven hours isn't horrible for all that. It isn't a flip phone.
why your phone is always awaking?

maybe you have to flash a new rom
If you want, you could try to flash a custom ROM. I had the same problem that you have, and I flashed Revolutionary S5, and now my phone lasts minimum two days with the same usage, maybe a bit more.
Too bad Tony Stark hasn't gotten involved

Titanium Backup will assist a little bit. When you do a backup of an apk it will tell you if the application is running. You can find all kinds of sneaky apps this way. Many of them were ones I didn't use and didn't really want. That will probably yield minimal results, though. Keeping a black background helps on my S3. Colors, widgets, and live backgrounds will drain the battery. Turn off the menu and back key lights. You know the buttons are there. Turn off all haptic feedback and key press sounds. Of course, try to lower the screen brightness. Leaving my data and sync on hasn't caused me any problems, but you will save some battery by turning them off when not in use. I also read a post about hidden menu options that ran even when they weren't meant to. That was an issue that destroyed battery life. Some ROMs also have settings for data connection type. You'll save power by telling your phone to not worry about gaining signals like 4g, 3g, etc. As other people have said, try out some ROMs that make battery life a big priority.
it CAN get better
if you want to have a good battery life, use custom rom and kernel (or a modified stock like omega rom), watch out for wakelocks + apply these settings:

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.
