hi all,
I've installed a raft of apps in the last few days (perhaps that was foolish) on my sim-free white Hero, and suddently the battery life has gone to pieces. It now won't even last the night *in standby with wifi off*.
Any ideas as to the known battery killers, or any way I can track down which is causing this? I don't really have to want to start removing apps at random and monitoring.
There's nothing particularly unusual in my list of running apps, following a power cycle (is there?):
Shake Awake, NetCounter, AK Notepad, OI Update & Countdown, Tube Status, Battery Widget, BBC News widget, Peep
(although that does raise a separate question: why do things like ShopSavvy, AK Notepad, start at boot, when presumably they're not really doing anything until you use them?)
Of course, I have other things that get started asynchronously, just not at boot, e.g. SMS Popup.
anyone got any ideas, please?
thanks much indeed.

I had the same issue when i put on battery widget, I saw the % going down while watching the phone.
oh! that's ironic
I do get the impression that it's more recent than that, but it could well be, I suppose. I'll remove it and see... thanks.
I've heard that the bbc widget drains the battery.
This is something Google should address with android market. The system should apply various forms of stress testing to all applications and rate them according to connectivity requirements, CPU load, power consumption etc.
I think for people who have a serious drain they need to hard reset and start again, put 1 program on at a time and leave it a day or so with that program on, finding out whats causing the drain.
Logically thinking, i'd expect it to be a program that is using internet in the background, like the bbc widget which could still be downloading without you knowing.
good points, ta.
I already noticed this. I checked the CPU load in idle mode and normally it should be around 10% (using "System Monitor").
Sometimes however, depending on what apps were running, it is increased to 30-40% and staying there constantly.
Closing all apps (incl. Sense) does not help either, the CPU load won't go down again until i make a complete device reset.
So i guess some processes are stuck in thise case causing the high load (and draining the battery empty).
My GPS did not disconnect, after foto geo-tagging, and that goes quick as well.
Also the BBC-app was installed, but got rid of it because I didn't use it. Might be a coincidence.
The BBC app polls really often. There's no setting to tell it how often to poll. It really kills the battery fast
I wonder though: even when the phone is in standby? something is killing me in standby. Oddly, it seems better if the phone is on
I'll try removing the BBC app overnight, and see...
then the battery widget tomorrow, etc...

Turn on usb debugging... download the SDK.. cd into tools.. and run
adb logcat
or to send it to a file:
adb logcat > log.txt
(and ctrl + C to stop logging)
Inspect the log file and you'll see what its upto pretty quickly. Maybe its overkill, but I fire that up when it starts behaving strangly.
EDIT: err to answer your question.. yeah the widgets wake the phone up to grab new data, which eats battery. The BBC news one seems to be polling reallllly often, which is unecesarily using power.
quick update: removed BBC News and Battery Widget (separately), no change; phone still dies overnight, in fact in about 5 hours on standby, from a full battery, to totally dead.
I just this minute discovered that my phone whilst in standby is still polling my IMAP server to try and connect, and I have a huge inbox, which it was prob failing to get the headers for. Seems like a possible bug that it still does this whilst in standby, but I've disabled that account anyway. It might be the cause...
What do you mean by Standby? Just inactive? Airplane Mode?
sorry, poor terminology, perhaps. No, not airplane mode, just the screen-off state it goes into after a few minutes.
It does seem a little bit of a waste, if the phone is going to spend all night checking for new Twitter, Gmail, etc, updates, when I'm not awake to read them? So I'd naively assumed that perhaps it wouldn't do that when it's in the screen-off state. Unless you've asked for notification other than on the top bar, of course?

To be fair, the phone doesn't know when you're going to asleep now does it? (especially if you're a night worker).
I notice that there's an application in the market now which can automatically turn airplane mode on according to a schedule, so that may help but of course this does mean you won't get phone calls!

No it doesn't but I'm developing a widget which will disable data access at certain times (dependent on user) so overnight it wont use data and save battery.

Right; I really meant the following, but worded it wrongly...
I had expected apps not to do data access when the phone's screen is off, unless they have been configured to notify via sound, vibrate or light.
i.e. if an app either isn't notifying, or is only notifying via the top bar, then it should disable its data access when the screen is off.
That would mean a short delay in getting updates, when the screen is back on, but I'd rather have that than spending much battery time pointless checking for updates when I'm not going to see them for ages, whether that's at night or just when the phone is sitting on the desk for hours.

aha! that sounds great, thanks in advance
would you update us here when you have something testable, please?
and if it's not pushing my luck to ask: any chance that it might also have a manual switch too, for those of us who go to bed at wildly different times?
Or perhaps there is already a way to disable data access manually, with a single setting change, without disabling the phone? I think there might be...
ah yes indeed, there's even an HTC widget to disable mobile networking, whilst leaving phone enabled. That will do for now
Its time we need a thread like this to ensure every G2 user is getting the best out of their battery.
Here are my tips:
- WiFi: Should ONLY be ON when you are actually using it!
- WiFi Sleep Policy=NEVER: it takes more time and power to seach for a Wi-Fi AP than actually staying connected to it. Settings > Wireless & networks > Wi-Fi Settings > MENU > Advanced > Wi-Fi sleep policy > Never.
- Bluetooth: Should ONLY be ON when you are actually using it!
- Use 2G when possible: If you know you are in a area with NO 3G support, than set your phone in 2G mode so it doesn't use power looking for 3G. Settings > Wireless & networks > Mobile Networks > 2G only
- Haptic feedback=OFF: I personally leave this OFF because minor vibrations are annoying plus consume battery. Settings > Sound > Haptic feedback
- Audible Selection=OFF: For obvious reasons, we use the touchscreen the entire time, enabling this will case battery drain everything you make a selection in Android, App, Web. Settings > Sound > Audible Selection
- Display - BRIGHTNESS=30%: I use about 30% brightness when indoors - when I am outside I turn it up brighter using Power Control widget. Settings > Display > Brightness.
Note: You can also leave it on AUTO, which is will provide optimal bnrightness with respect to ambient light.
- Display - Animations=Your choice: I personally have ALL of them enabled, but that is scarificing a small amount of battery power. If you do NOT need the pretty transitions, you can opt for other options. Settings > Display > Animation.
- Display - Screen Timeout=30: I leave mine at 30 seconds, as I think that's ideal for most situations. Settings > Display > Screen timeout.
- Location - Wireless networks=OFF : The phone uses tower and signal strength to calculate your APPROXIMATE location, which is a waste when you have GPS. NOTE: This feature assists in fiding your location indoors. If you plan on using GPS outside on than you should leave it OFF. Settings > Location & Security
- Location - GPS=ON: It should be ON if you plan on using MAPS or Navigation. NOTE: GPS is ONLY used when system needs it! Having it Checked OFF does NOT help battery life. The only time GPS is active is when you see the icon in the notification bar. Settings > Location & Security
MAJOR CONSIDERATIONS
- DATA - (3G/HSPA+) - Hogs the most battery, even more than the brightness of the phone. The reason for that is when you are surfing, searching, texting basically anythin that requires 3G/HSPA+ data the radio, CPU, and RAM are always working to ENCODE and DECODE data going in and out the device. This process requires all 3 major components to work simultaneously which draws more power from the the battery!
- Widgets - Widgets like facebook, twitter, weather, news do have processes running in the back which draw DATA depending on your refresh options. ie, You will draw less power if your facebook/twitter updates every 3 hours instead of 1.
- APPS - Always keep in mind that APPS like messengers and others which constantly need data DO run in the background. Background apps will draw DATA AS needed, which bring it back to the point above. Always make sure that you SIGN OUT of APPS that require background data, IF you don't plan on using them.
- Live Wallpaper - yes, it looks pretty as we all know it. Sadly, the truth is that both CPU and GPU are working hard in the background to bring a smile to your face when you look at the screen. Live wallpaper will affect your battery about 5 - 10%, dpepending on which one are you using.
- Vibration - Considered important as well.... if you are a CONSTANT texter/EMAIL-er AND you dont need Vibration, than you should turn it off. Vibration actually takes more battery power than actualy sounds.
- Volume - Should be considered important because the higher the volume the more battery power it'll take. If you can do just fine with a Mid-level volume than you should set ringer to mid level!
YOU SHOULD NOT USE A TASK KILLER APP
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
^^^ That explains everything about it ^^^
I'd be happy if one of the MODs made it a sticky, so we dont get Qs or reposts
and ofcourse I will also include any tips you guys have.... please leave a comment and explain why&how you think it saves battery life. I will than add it in this list
thanks for this.
auto-brightness works for me. also, wireless network location is kind of necessary because gps won't locate you when indoors. when you're indoors you don't really need an exact location anyway because you probably know where you are. but using wireless networks to get your approximate location enables you to quickly search for things nearby.
one more thing I might add - my G2 seems to constantly switch between edge and hspa. I think I recall this being an issue for the N1 too. if I'm not mistaken, switching taxes the battery. so I set the phone to only use 3G (or only 2G depending if I want to use less battery). you have to have Anycut. then crete a shortcut to "phone info." here you can control the radio behavior. WCDMA is 3G, while GSM is 2G.
also, question: anybody ever have any luck conditioning their battery? I keep hearing that it improves battery life but it's never really helped me
Thanks for the tips! Though, what are you sources saying that WiFi sleep uses more battery? Auto-brightness does work for me, it is just very slow to make changes and tends to be on the brighter side.
most of these tips are pretty much universal for most of the current and past android phones.
LET IT BE KNOWN the main reason for battery drain (slow or fast) is APPS. They drain more than talking on the phone. They also are the main reason your screen (the next big battery killer) would stay on. In other words, don't complain about battery usage if you're using your phone constantly throughout the day @ work or home. ITS NOT GONNA BE GREAT!

As an Electrical engineer, I work with wi-fi chipsets... The process is that when wifi is "sleeping" it temporarily goes to OFF when you lock the phone. [exception: when not using apps like pandora]. So when you turn the phone back ON, WiFi turns back ON and searches for the AP you were connected to. >> this process of turning OFF, ON, and SEARCHING, requires a more battery power than staying connected. When you are connected the router and phone are exchanging information (packets) on AS needed basis like when we use 3G/2G.
i did try Auto Brightness, its a bit Bright for me, i'm gonna continue to use it for the next few days, see how I like it.

Auto-brightness seems to be buggy on the software side. The light sensor is very quick to detect changes, but the brightness doesn't drop back once it goes up. I feel that the brightness gets set to full at too low of a light level too. Using a screen protector and case does help a little by blocking some of the light, but it's not enough.
Actually, having GPS on consumes battery even when it is not used. And quite a lot. I have seen mayor battery boost after I started to turn it off when I do not use it. (on G1).
I've done some monitoring with PowerTutor and noticed that the Facebook app significantly drains the G2's battery (even when all features are disabled). If you sign out of it you should notice a 2+ hour increase in your battery life. People in my other thread have confirmed this and I think it might be a bug with facebook 1.3.2. I recommend making a link on your home page to m.facebook.com instead of using the facebook app.
I have also noticed that the e-mail app (NOT G-MAIL), when using Exchange ActiveSync, drains a good bit of battery when used with a Hotmail account (I'm not sure if other exchange servers have this problem or if the problem is in the e-mail app itself). The remedy that I have come up with for this is to make a new G-mail account, set hotmail to forward to it, and then on the gmail website go to Settings-> Accounts and Import and under the Send Mail As: section, add your hotmail account to it and set it as the default.
This way you get g-mail's lightweight mail pushing (which is just as fast as exchange) and it's transparent to you and everyone who has your hotmail address.
Besides those two tips, I recommend using PowerTutor to diagnose any abnormally low battery life issues you may have. My power usage is way down after fixing these two problems. Once in PowerTutor, go to View Application Power Usage, set Time Span to total, disable LCD monitoring, and set Sort By to Energy usage. Reset the power profiler and lock your phone and let it sit idle for about 30 mins to 1 hr, and then look at the application power usage. PowerTutor will probably be the top one, but you should also see what other applications are sapping your battery life.
Note: PowerTutor itself drains battery, so you should not constantly run it. I think it is set to start automatically so you will want to go in to settings and turn that off.

i think with exchange rather than having the user select the refresh interval (ie 30 mins, 1 hour) the system is a ALWAYS ON connection which constantly checks your e-mail. As oppose to G-Mail..... they as get PUSHED to your phone by google's servers every time you get an e-mail as oppose to an ALWAYS ON system.
There is a lot of hush going on about the facebook app draining the battery... hence I addressed the widget/app parts..... as of now I think we should wait for an update to see how things change, it is a software bug.
Location - Wireless networks=OFF
By turning this off won't you in turn be turning off assisted GPS?
IE - the GPS will not have an approximate location and begin locating from there but will rather have to cycle much further to dial in and take much longer to calculate your position?
Just asking - if you haven't noticed a difference then that's cool.
I also noticed shop savvy was taking up alot of my battery drain. Looks like it was running in the background non stop. I uninstalled it.
Isn't WCDMA the HSPA+ network and CDMA the 3G? I currently have mine set to edge only since the speeds are slow all across the board in my town. Even on the phones down at the tmobile store. Hoping its just a minor tower issue in my area.

Exchange activesync should push email. I had set it to push and hotmail supposively supports this. Even if it doesn't, I tried setting it to polling and it still seemed to use a decent amount of battery life. Anyways something is wrong with activesync pushing.

Exchange uses Activesync, which pushes messages as well. The ongoing sync is for contacts and calendar items which if you do not make a lot of changes, change to off and sync then yourself manually.

GPS ONLY uses battery when it is in use. You will know this because the icon will appear when it is being used. It doesn't use battery just being on. WiFi and Bluetooth do because they have to constantly "keep their eyes open" for things like networks and bluetooth devices that want to pair/communicate.

I noticed this too on other Android phones but not on my G2. It would just show up in Battery Use even though I wasn't using it. If you want to see what is keeping your phone awake you can use the hidden Battery History menu. The "partial wake usage" is usually a big contributor for bad standby times. You could also try changing from WCDMA Preferred to GSM Auto PRL. This helps some people.

A lot of people have been reporting that this feature as of NOW updates every hour, regardless of which services/apps need it. If you ask me, I haven't noticed any significant amount in the time it takes to get GPS location having that feature turned OFF. If you do a cold start (i.e. restart your phone) than the GPS will take a couple of more seconds to initialize for the first time use. However, from than on everytime you use the GPS it shouldn't take more than 10 seconds to acquire your position.

Sure... At the phone menu (must be the native dialer), dial *#*#4636#*#*. Then chose Battery History and you can use the drop downs to control what you view. If you go to "phone information", you can change the preferred network type. Here you can force 3g only, etc. WCDMA Preferred fights to get a 3G signal and keep it. GSM Auto PRL uses a downloaded list to choose whether to use 3G or 2G, thereby saving battery in certain cases.
Being new to Android, I'm trying to figure out the WiFi sleep policy setting and how the lock screen affects things.
My issue is that if I leave the tablet unplugged overnight, with the screen off, I lose about 10% power. The Battery Use History Details screen shows that WiFi is on consistently and it seems to be awake when it shouldn't be.
So here are my questions:
1. Does disabling the lock screen cause the device to stay awake when the screen is off? It seems like there is a correlation between when I disabled the lock screen and it staying awake consistently, but it might have been an app I installed.
2. If I did not activate the device on the cellular network, and disabled mobile data, is there a WiFi disconnect policy that will turn on WiFi only to poll once in a while for mail and other updates but not stay on consistently?
I think I might be running into one of the big differences between Android and iOS here. iOS' push updates allows the device to use data collections very efficiently to get updates from the network, because it only has to poll one data source to get updates for all apps who require it. In May 2010, Google introduced Cloud to Device Messaging for Android, but how many apps use it? And does the device have a WiFi policy that only lets apps that use C2DM do their updates and then shut the connection off?

By default your wifi connection is set to never shut off. Settings/Wireless & networks/wifi settings/wifi disconnect policy. Change this to when screen is off.
Thanks, but I still want to be able to turn on my device and see new messages quickly. I assume it won't check for new mail at all with the WiFi off.

I don't think you can do this with a stock android os. Its either on or off. Now you can download apps for phones, no idea if they work for tablet yet. Think one is called tasker and another juice defender. Basically they tell the tablet when it can and can't use data.
If you are on Stock Motorola Lollipop 5.0.2, check your Battery History in System Settings - you may notice Wi-Fi is constantly active, even when you turn it off.
In my case, the following setting in Viber was the cause: Settings > General > Wi-Fi sleep policy > Change to 'Use device's settings'
Instructions:
Firstly, go to: Settings > Wi-Fi > Advanced Wi-Fi > Keep Wi-Fi on during sleep > Change to 'Never.'
The issue appears to be that certain apps are keeping Wi-Fi active in Lollipop. Not every app may offer this setting related to 'sleep policy', a workaround is to use the App Settings Xposed Module - which allows you to disable such a permission for individual apps.
The permission can be known as: Change_Network_State.
After making these changes you may need to turn off Wi-Fi and restart phone.

This is true, when phone sleeps - there is no Wi-Fi data connection.
Rather than leaving Wi-Fi on however, some people might prefer the phone wakes up every 15 minutes / 30 minutes / 1 hour, and enables Wi-Fi for 1 minute - allowing any messages to arrive. Many apps can do this, one example is DS Battery Saver.
There is also an argument that if you use Wi-Fi a lot, it's better to leave Wi-Fi on during sleep, because excessively enabling and disabling it is costly in terms of battery-life.
I've been using stock Lollipop on XT1008(Moto G Forte, I read it was just a "commercial" variant of the XT1032).
As far as I can tell, my phone doesn't report high Wi-Fi usage, but I disabled an option that I think it´s more responsible than the one mentioned here, that's "Search Always Available", this one was turning on my wifi when I even shut it down, wasting more battery than keeping it on.
Currently, my phone has been on like 13 hours and has 13% left, with a WiFi usage around 85% of the time.
Thanks for making us aware of that option in Viber.
But even after disabling that option in Viber, in the battery graphic seems like wi-fi is always active. Is it because I will also need to set "Keep Wi-Fi on during sleep" to "never"? But if it's set to never, doesn't it mean that when phone screen is off, it automatically switches off wi-fi even if you kept it on from the toggle?

Yes, 'never' means Wi-Fi is off when phone is sleeping. There is also the advance Wi-Fi option 'Scanning always available - which' you might want to disable.
Double check you have changed the setting in Viber, and you may need to reboot phone. It's also possible another app is causing Wi-Fi to always be active, for some it's Whatsapp.

Ok so that option works as I thought, so for correctly receiving notifications with screen off it should be set on "always". I double checked on Viber's option and it's set correctly, then rebooted, plus scanning always available is off, geolocation (which can keep wi-fi on) is off and apparently there are no things that can keep wi-fi on.
Whatsapp does not allow to set wi-fi behavior, and the strange thing is that I have the same apps I had on Kitkat, where I didn't have such problem of viewing in battery graphic.
I am having the doubt if this may be only a Lollipop graphic issue or if wi-fi actually stays on...

That's why I mention the 'App Settings' module in OP. I believe Whatsapp can and does cause this issue - there is just no setting within the app itself. You can check what permissions apps have by using 'App Settings.'

Mmm yes I saw that...but I'm guessing that without root there's nothing else to do, right?

No. Root would be necessary for changing permissions. However this issue may have been resolved in Android 5.1 - removing the need for this fix.
Wifi should be lefy alone as default to "never sleep"
Wifi should never sleep, even if the phone's cpu sleeps. Wifi will receive messages from whatsapp or whatever and wake up the cpu.
But if you put wifi chip to sleep, the phone will connect using 2g or worse, 3g or HSPA, and drain even more battery.
Wifi comes by default to "never sleep" for this reason, it is more battery efficient than 2g/3g.
And if you dont have wifi at home, all you have to do is slide down the menu and turn of Wifi. No need to change internal configuration on behaviour who only make things worse.
On the other hand, Viber is known for years to be a battery abuser.
I have been using android for years, and wifi policy was always the same, and my phones have idle times of several days
i even published some screen shots of my moto defy and moto G with a full week Idle without charging.with whatsapp and Wifi polocy never sleep.. With viber i wouldnt even try to make it last 2 days.
I am on my 5th charge, and Google Play services is my number one battery sucker.
I have location services, BT, on 24/7. I only connect to BT when in my car though, so 5% of the day maybe.
If I let me phone sit idle for about 4 hours, Google Play services will be the only thing that consumed battery.
Any advice on troubleshooting it? So far i've tried disabling NFC, google hang outs, ambient screen. I am trying things one at a time to see what's causing it.
There are no wakelocks, because I click the graph and I show it's only awake when I am actually using it. GPS is rarely, if ever on. WIFI is never on, as I have green signal everywhere + unlimited data via tmobile. I also do not have any other always connected apps like facebook, or facebook IM, twitter, or whatsapp, etc.

I am getting the same thing right now. I didn't yesterday.
I know it shows Google Play Services if you have Google Photos backing up your photos and videos. It is defaulted to do it whenever you are on wifi I believe. I have mine set to only backup while charging. I still see the Google Play Services drain though even with it not backing up, so I think my drain is coming from some other place.
Yeah, I am going to turn off background data, and if that's the culprit. I will play with each of the back up options. I only have a few enabled. I do have google photo's set to sync when on cell network or wifi, because I have unlimited data I do not care when they go up.
I noticed an odd bug when I unchecked google+ and google+ uploads as OFF/not sync, my google photo option to sync was gone. I enabled it, and it showed up. I have since rebooted a few times, and disabled those (did this an hour or so ago), and it will still sync, so maybe that was it? Will report back.
Currently enabled sync options:
app data
calendar
chrome
contacts
gmail
google opinion rewards
google photos
google photos backup

I saw this after upgrading to the newest factory image. let things settle and it was back to normal on the next day. Also updated to play services 8.3.0.1
I actually tried to do a reinstall the other day, and it brought me up to 8.3.01 (2385995-440) ... which was what it previously had.
Are you saying you just wiped your phone and started from scratch again?

I didnt wipe anything. I flashed the system.img and vendor.img from the Nov. update and i then noticed that play services was eating up about 22% of battery on a normal cycle. Updated to 8.3.0.1 and after charging and watching on the second go around, it seems to be returning to normal. Down to 44% and play services has only eaten 4%.

4% seems solid for 66% bat used... i'll try that if this doesn't work. Does flashing just system.img and vendor.img muck with any data?
maybe try wiping the cache partition -
Nexus 6P Wipe Cache Partition
Power Down the Nexus 6P
Boot the Nexus 6P into Fastboot Mode
Boot the Nexus 6P into Recovery Mode
Press the Volume Down Button to Control the Highlighter
Highlight the ‘Wipe Cache Partition’ Option in Recovery Mode
Then Press the Power Button to Select This Option
Make Sure the ‘Yes’ Option is Highlighted
Then Press the Power Button to Select This Option and Confirm the Wipe
Wait Until the Nexus 6P Wipes the Entire Cache Partition
Make Sure the ‘Reboot System Now’ Option is Highlighted
Then Press the Power Button to Reboot the Nexus 6P

What does wiping cache do again?
I disable.any Google apps I don't use ,which most if them,I have Google now always listening and I don't use chrome which seems to hit the battery,and play services is hardly ever in my battery list,but today a new play service update and reading reviews it's sucking battery by all accounts ,not seen it yet myself
I have wiped cache and I will report back.
After reboots it still is eating up battery like nobody's business. Bone stock not rooted too.
Wifi and bluetooth on, location set to device only. Google Now on, "okay google" detection from anywhere.

i suffer no hardships doing this -
Battery Tips for Android
1. Toggle off High Accuracy GPS Mode, Bluetooth, NFC,
Hotspot/Tethering. Toggle on only as needed. (Set GPS Mode to "Battery
Saving" Mode).
2. Display Brightness - Turn off Auto Brightness and Reduce Setting
Bar to Minimum Acceptable to you.
3. Sign out of any unused Google Services like G+, Google Now, Hangouts, etc.
4. Disable Location Reporting and Location History.
5. Beware of constantly syncing in background Apps and Bloatware like
Facebook, Twitter, Weather Channel, Games, Google News/Weather,
Non-Push Email, etc. Set Sync interval for every 1 hour or more and
change settings to stop the syncing of data you don't need. Delete
their Apps and use their Web Page if acceptable.
6. Turn Off Hot Word "Hotword Detection" Always Listening Mode in
Google Search if you don't use it.
7. Turn Off Auto Camera/Photo Upload or at least set it for Upload on WIFI Only.
8. Turn Off Vibrate on Touch for Display, Keyboard, etc.
9. Turn Off Touch Sounds and Unlock Sounds.
10. Turn Off Ambient Display/Active Display Notifications if you don't need it.
11. Don't use a Live Wallpaper. Use a dark wallpaper if possible.
12. Set Display Sleep Setting to 2 Minutes or Less.
13. WIFI Settings - Advanced -
a. Network Notification - Set as OFF.
b. Keep WIFI on during Sleep - Set as ALWAYS if you regularly use
WIFI. OK to keep WIFI on if you regularly use it.
14. Scanning Always Available - Set as OFF - Wifi scans for networks
(location assist) in the background by default. Go to Settings >
Location > Overflow (three dots at top right) > Scanning and change
the setting for Wifi and Bluetooth.
15. Turn Off Always Vibrate in Gmail/Email.
16. Be careful of using too many Live Widgets and what/how often they sync.
17. Set MS Exchange Sync at 30 Days or Less if you use it.
18. Do NOT use a Task Killer App or Battery Saver App.
19. Uninstall ALL Apps that you never use. If you haven't used an
App in one month, uninstall it.
20. Reboot your phone at least once a month.
21. Wipe Cache Partition at least once a quarter or after every OS Update.
22. Consider a Factory Data Reset with a manual re-sync, manual
reinstall of all data and Apps after every major OS Letter Update.
Make sure that all of your data is first backed up to Google and
Dropbox, etc.
"I SUFFER NO HARDSHIPS DOING THIS" - this means that i personally am
giving up NOTHING with these tips. i'm not giving up any features.
there are no tradeoffs for me. a tradeoff or a hardship would be to
turn off PUSH email or use AIRPLANE mode during the day etc.
you have to find your own balance and the tips list is a start but you
must come to your own conclusion as to what's important. it's personal
preference but these are not a big deal to me at all as they do not
affect the function or operation of my phone. these tips do not
deteriorate my experience.
you don't HAVE TO do anything. the point is you if you want to
MAXIMIZE battery life you can turn things off that you aren't using.
it only makes sense. there is a FINITE amount of juice in ANY
battery. you choose how you want to spend that juice. by default most
of these devices have every feature set as ON whether you use them or
not. i prefer to change the settings in my phone to only use those
features that i personally use and need so i can maximize battery
life. i don't leave all the lights and TVs on in my house 24/7 - i
turn them on when i need them. i'm not giving anything up. my phone
does everything exactly like i want it to. i'm not missing out on
anything. it's no hardship for me. it's life. life is a delicate
balance. it's up to you to find that balance.

I am doing 70% of what you listed out, and google play services is currently at 3% of battery with 81% remaining, it's my highest user under screen with an hour. Don't get me wrong, great battery, but why is it using so much?
I wiped cache and it seemed to help a ton. Almost 3 hrs screen on time, 24 hours off charge, 35% battery remaining and Google Play Services is only at 3%. Much better.
its "Ok Google" "Always Listening"
I lost 12% in 7 hours overnight with it on and 1% with it off (On 4g)
Let me try wiping my cache then. Also, OK Google is not always listening, I never really use it anyway. I only use voice for texts sometimes.

Bluetooth is your problem. I turned mine off and immediately my phone starting to sleep again.
I leave my BT on all the time, it only connects in the car though (40 minutes per day). I do not see bat drain for that. I also left it disabled for a day, same google services % usage.

This has always been off, why would anyone even want it on. BTW, solid list, like I said, I do about 70% of it already.
