Battery tip for people with bad battery life.

I've had bad battery life since I bought this phone on release day. I would get no more than 1.5-2 hours screen on time. The battery wouldn't last more than 12 hours. I've been messing around with it since then but still had bad battery life up until the last few days. Now I get 3.5-4 hours screen on time and I'm a moderate user.
Here is what I did:
1. Go to Google maps and then go to settings and untick anything that is ticked then click on "location reporting" and set it to do not update your location.
2. Go into the phone settings>location services and untick everything. When you want to use maps just turn on gps.
3. Get the app "battery calibration". First charge your phone to 100% and keep the charger plugged in and then go to the app and Press calibrate. Then use your phone till the battery is dead (turns off) and plug the charger in and let it charge to 100% while it is off.
Turn it on and then use it till the battery is dead again and charge while off to 100%.
I'm not saying this is guaranteed to work for you but it has for me.

You know my problem is I did that and when on Jb lib battery drain like crazy.Back on ICS no problem with battery can you explain that why on ICS calibration is not needed ???

First two items I agree on. GPS uses up a lot of battery, though from personal experience, it didn't dent my battery too much anyway as long as I don't have running apps using it.
But the last point. I believe those battery calibrations are actually useless. There was some article from the android team describing why.

The 2nd and 3rd are completely useless.
People who use gps know that even if you tick those location services, it only gets enabled when an app requires gps. Thua, battery is only lost if you use loads of navigation services. Unchecking those won't do any good.
Battery Caliberation is just what you can call the perfect reading that is shown on your status bar. Ultimately, whether you caliberate or not, battery gets charged upto 100% only. It won't surely exceed that.

A better idea:
Disable auto sync for accounts
Disable GPS (and wifi gps)
Disable auto backup of Gmail account
Set wifi sleep policy to “when plugged in”
Disable motion
Check your apps settings and disable useless background sync​

Setup a static IP via your router.

I had issues with Chrome Sync - when enabled it prevented phone from going into deep sleep. So if you use Chrome and struggle with battery life this is one more thing to look at ...

Official Facebook app uses a lot of power and waking device for many times. Use browser for facebook or alternatives...You will see the diference !

good list id like to add:
freeze unused apps/battery hogs if used sparringly (with titanium backup)
set wifi to always on, switch off manually when not in use
firewall apps that dont require internet

I agree on the Facebook app. I will charge my phone to full, reboot it, and then let it sit overnight without using any apps and it will be one of my top processes in better battery stats. I really like using facebook simply for the picture and phone number syncing. I guess I could always go back to haxsync. On my Galaxy Nexus since I can't use facebook app to sync I just use mobile page and it definitely is better on battery life.
I've been trying to improve my battery life on 4.1.1 LIB as if I leave it on Wifi overnight with no use after reboot and full charge I'll see Deep Sleep at maybe 90% if I'm lucky. I'm losing almost a full hour of sleep time over the course of 7-8 hours. I think Facebook is part of it, also it seems to be worse when I use the S3's built in alarms.

Go into Settings -> Location and disable everything? You mean that we should disable:
1) Use wireless networks (location determined by wi-fi and/or mobile networks). I really don't see how this saves battery.
2) Use GPS satellites. This uses up battery ONLY when an app requires GPS (and when the icon shows).
3) Use sensor aiding. See above.
4) Location and Google Search. (only used to get your location when you're connected to GPS and/or wifi/mobile network).
I really don't see how this saves battery.
On a side note, one might want to freeze unwanted apps, not use too many live wallpapers, sync only when needed, and get rid of unwanted widgets. THAT might help.

Better tip. Use your phone with everything turned on as it was designed like I do and get 4 hours + screen on time, and 1 to 2 days useage depending on how much it's used.. simples...

I really don't see the point of buying a phone like this and turning everything off!
Google now won't work properly with all the location stuff switched off.
I always get through the day with everything turned on, in use power saving at work and switch off wifi that's it.
If the battery runs down have a back up waiting, galaxy s3 owners are always going on about it being good that our phone has a removable battery and iphone doesn't but there are still many people not happy that their battery runs down quick!

The best thing I ever spent on for this phone was the official samsung battery kit. At least I don't have to worry about the battery at all and I can leave all the features on.

The best app to see exactly what's happening on the phone is "Better Battery Stats".

Yes that's true but this is not for everyone. I don't use Google now and why should I use wireless networks when there is a built in GPS.

Thank you OP. That was the problem with my phone. Now its awake when the screen is on. Before that, it was awake every 5 minutes. !!!!

And after you've turned every single feature off, you can stand back and admire your Nokia 3310

You're only turning of location services. Why does the phone need to know where you are 24/7? Just turn it on when you need to use maps or location. Not hard.
My car was designed to be driven, does that mean it should be left on while I'm not using it? Think about that.

Battery Drain

I've read through this thread (http://forum.xda-developers.com/showthread.php?t=2385843&highlight=battery+drain) but did not find a solution. A little about my device: it is not rooted and is completely stock. I did not have battery drain issues when I was on 4.2.2, but ever since I updated to 4.3, I've experience this issue. I would lose about 20 - 25% battery life through the night. When I wake up, it would be around 75-80% full.
I've looked at my battery stats and it seems as though Android OS is 19% and Google Services is at 17%. Prior to updating to 4.3, I would be able to toggle the GPS on and off simply by using the Power Widget, but after 4.3, I noticed when I toggle the GPS icon, it would take me to LOCATION ACCESS. As of right now, "Access to my location" is ON .. GPS satellites is UNchecked .. and Wi-Fi & Mobile network location is CHECKED. I tried to turn location access OFF last night and have everything unchecked, but it didn't seem to make any difference.
What's going on???

Feel for you bro. I have the same issue as well. It's like 4% drain per hour, only by Android os.

To decrease google services battery consuption you can delay the frequency of sync in the settings! But i give you an advice, flash a costum kernel like franco or matr1x and you will enjoy a lot of extra battery life

Help reducing battery drain

So, I'm seeing a lot of battery drain from voice calls, WiFi on and deep sleep. I've been trying to change some setting to help reduce this, but I don't want to cause issues. Can someone let me know if the following will help or cause issues.
I've set tasked to turn off data when any phone call is in process, because I don't multitask and use data durning calls. I have also set tasker to turn off data when connected to WiFi, although this may not be needed. I was considering turning off WiFi during sleep, but this may cause more battery consumption due to data and searching for signal. Also, what can I do to reduce power consumption during deep sleep.

When your phone is in deep sleep, your phone's battery level stays flat. Simply, this means no power is being consumed. Another way of putting it is that deep sleep DOES NOT drain battery power (maybe just a bit after hours and hours in standby mode).
According to those stats, it doesn't seem like anything is out of place. The phone was on for 5hrs and 37mins, it was awake (assuming you were using the phone during that time) for 2hrs 13mins. It was on deep sleep for 3 hrs and 23mins. Wifi was on for nearly 5hrs.
The best advice I can give you is root your device, install twrp and flash a custom kernel. (If you haven't already.)

OK, I've just started using better battery stats so maybe I'm not understanding the info correctly I thought from the pic above that a majority of battery consumption was from WiFi and deep sleep, but when I look at the battery stats in settings that's not the case.
Ok, if I look at the updated info below it seems that my battery consumption is mainly the screen on time. Right now my screen is set to auto brightness. Does this seem like an appropriate consumption?

Oh and I've been running a custom ROM and kernel since my 1st day owning this phone.

I have heard that google services drain battery fast, so have you tried to set the location to either "battery saving" or "device only" mode in Location? In addition, if you do not use Google+, try to either uninstall or disable it. After you have done those steps, go to recovery and wipe cache and dalvik cache then reboot phone.

Yep. Kill the Google services if not needed. Futhermore deactivate every HW device which is also not needed at the specific moment (GPS, BT, ...) ... the Battery Stats Plus will give you even more hints.

How do you deal with NlpCollectorWakeLock?

Battery life on this phone is amazing under use, but only average on standby, which is the only negative thing I could say about G2. I routinely lose 2%-3% battery over night, it was the same on JB and now on KK.
I've been checking the wake locks and it is our old friend Google Services and its NlpCollectorWakeLock that keeps the phone awake about 10 minutes a day, since Google likes checking our location 1000 times a day. Turning location off doesn't help at all.
What are your experiences and how have you been dealing with this on G2 specifically? Don't just say install Wakelock Terminator, if you used it also share your experiences with it. Does Greenifying make a difference and what did you hibernate? Did you have any issues afterwards with apps that use location?
And most importantly, did it have any effect on battery life in standby?

Can't remember whether Knock On/Off feature has anything to do with the NCWL but just disable it and see what happens.
Also, down 2-3% overnite seems normal to me.

Normal but we had 0% even on ICS 4.2.2, and on 4.1.2 my previous phones did managed to spend 0% overnight

Yeah, constantly running Location Services bugs me off too.
Maybe you could find solution in that http://forum.xda-developers.com/google-nexus-5/general/nlpwakelock-nlpcollectorwakelock-t2551846 topic, I didn't read it

Location services disable location reporting and history ... That helps decrease it (only do this if you don't use Google now location based features)... Also you can set location to device only if you want ... And greenify the Google maps app ...

... did you actually just complain about a 3% battery drain in 6-7 hours of idling or whatever you define 'night' as?...
Getting back to the topic, one of the bigger things you could do to reduce NlpCollectorWakeLock is disable Google Now. I personally don't find it very useful in my country so I never keep it on. Thus, I get that 3% battery drain overnight with WiFi on.

Battery life

The first week or so I was very happy with the battery life. I could easily get two days out of a recharge. However for some reason now the battery drains much quicker and I can barely make it to the end of the day with my normal use. The "Android System" item on the battery stats is 29%. That seems too high. I have been installing apps recently so I wonder if an app is causing this. Any advice?

Things I have done to get better battery life (or at least feel like I get better battery life):
Disable battery percentage display (it never helps)
Settings -> Display -> System Icons -> Battery Percentage (unchecked)
Change from LTE to WCDMA (preferred)/GSM (i get horrible LTE signal)
Settings -> More -> Mobile Networks -> Preferred network type
Disabled the default Android Device Administrator
Settings -> Lockscreen & security -> Device Administrator (unchecked)
Set Wi-FI to never stay awake
Settings -> Wi-Fi Settings -> Settings -> "Keep Wi-Fi on during sleep" (set to off)
Disable Bluetooth when not in use
Disable apps I dont use.
My best bet is that your Bluetooth or Wi-Fi are in a consistant ON state. Disabling bluetooth when not in use, and setting the Wi-Fi sleep policy would be the low hanging fruit if you havent done that yet.
If none of the above work then I would suggest one of the following:
1.) ADB into your phone and look at logs (logcat, dmesg, ...) to determine if there are any exceptions that could be causing the system to "hang".
2.) Factory reset

Thank you so much for the detailed answer. I feel a bit stupid now, but everything was solved with a simple reboot. Who knows which app must have hang. I will keep your message for future reference. Many thanks again.

So after the Nougat update I'm back at square 1. Battery life is much worse. For an android phone is not that bad. It easily lasts through the day. However on MM I used to get 2 days with the same use (and this was one of the reasons I got this phone).
