General Guide to Maximizing Your Android Phone’s Battery Life
You’re no doubt reading this article because you’ve got a shiny new Android phone, but there’s just one problem: you’re so addicted that the battery runs out on a daily basis. Instead of putting the phone down, let’s maximize the battery life.
Saving your battery life isn’t rocket science—the general principle is to get rid of the things that are draining the battery the most, and trim down other things that you need to use, but maybe can tweak a little. Keep reading for the full explanation.
Use Android’s Built-in Battery Usage Screen
There’s a screen built into Android that most casual users probably don’t even know about, and it can tell you exactly what is killing your battery. Head into Settings –> About Phone –> Battery use to see what has been killing your battery life.
From this screen, you can usually see what apps are the worst offenders, and you will probably notice that the biggest problem—at least, the biggest one that we can fix—is actually the backlight on the phone. Personally I’d prefer to talk less to other humans, but that isn’t always an option!
Note: on my phone, I’ve already configured the backlight to not be very bright—normally that number would be a lot higher.
Adjust the Backlight to be Less Bright
Since we’ve already determined that the backlight is usually the biggest problem, you should probably adjust the settings. Head into Settings –> Display –> Brightness, where you can choose to automatically adjust, which usually works fairly well, or you can just turn the brightness down to the lowest acceptable level.
You should make sure that the screen timeout value is set to turn off quickly as well.
Disable Your Wi-Fi When You Don’t Need It
Wi-Fi can really speed up accessing data on your phone, but it can also be a big drain on the battery if you don’t need it enabled, especially when you are out and about… The phone will try and scan for a wireless network even though you may not want it to.
To enable Airplane mode, you can head into Settings –> Wireless & networks–> Airplane mode.
You can easily toggle the Wi-Fi on or off with a widget or shortcut—there’s a built-in widget included in Android phones, or you can use the AnyCut or BetterCut utilities to create your own shortcuts to directly turn them on or off without requiring a widget.
Disable Bluetooth if You Don’t Use It
If you aren’t using a wireless headset, there’s no reason to have Bluetooth running all the time, and you should probably cut it off to save the battery life. If you never use it at all, head into Settings –> Wireless & networks–> Bluetooth.
You can also enable or disable the Bluetooth when you do need it, using the power widget.
Use the Power Widget to Easily Toggle GPS, Bluetooth, Wireless, and Screen Brightness
Android includes a built-in Power Widget that can easily toggle these settings on or off—just long press on the background of one of your screens, choose Widget –> Power Control to add it to the screen. You’ll notice in this example screenshot that I’ve got my GPS enabled but I’m not using Wi-Fi or Bluetooth at the moment—the icon all the way on the right lets you easily toggle the screen brightness settings.
This is probably the simplest and easiest thing that you can do to save your battery without having to dig into the settings all the time.
Disable Apps that Sync Constantly
The built-in Email application (not the Gmail one, which uses Push technology) can suck the battery badly, because it syncs on a too-regular basis, especially when you have lots of accounts—each one of them is set to sync every 15 minutes. You’d be better off setting it up to sync manually, but if you want it to sync automatically, you should set it to sync less frequently.
Open up the Email application, head to your account, and choose Account settings –> Email check frequency from the menu. Change this to something more like an hour… or never. You can always hit refresh manually when you want to read your email.
The same thing holds true for other accounts, like Twitter clients, which are even less important to update all the time. For Seesmic, you can head into Settings –> Background Updates from the main screen. For the official Twitter app, the settings are similar.
The Facebook application polls automatically in the background, and you can customize the refresh interval for that as well—if you don’t need Facebook updating all the time, you should set this value as high as possible.
From the main Facebook screen—the one with the icons—head into Settings –> Refresh interval from the menu.
Disable the GPS Location Features
One of the biggest battery sucking features on my droid is the GPS… When I have navigation going, the battery dies far too fast, so I end up having to keep it plugged in the whole time I am driving. This makes sense… but what you might not know is that a lot of other applications use the GPS as well.
You can also change the GPS to use wireless networks, and uncheck the option for Use GPS satellites—this will make the GPS a little less accurate, but it will save your battery. Note that you probably want the real GPS enabled if you’re using Google Maps Navigation.
Additionally, you should turn off the geolocation features in your Twitter client, weather application, or whatever other apps that you really don’t need them in. If you want to keep it enabled, that’s great, just realize that it does drain the battery, so uncheck this option to help.
Use a Task Manager to See What is Always Running
It is a wise decision to have a copy of Advanced Task Cleaner or a similar application installed on your phone to help you kill applications that don’t need to be running, but more so that you can see what exactly is launching itself repeatedly in the background. You can setup an auto-kill list for applications you don’t use that often—make them cut off when you shut off the screen, or after an interval.
Note: If you’ve configured your application settings to not pull down lots of data or do checking in the background, it’s not quite as important to keep tasks killed all the time—that’s really what kills your battery, not having them sitting idle.
You can also configure advanced task manager to show you CPU usage for each app, which is a more useful meter than memory usage when it comes to battery life.
Disable or Remove Applications That You Aren’t Using
Once you have identified the application that you don’t want running all the time, check in the settings to see if it can be removed from running in the background. Some applications will give you an option for notifications that can be turned off if you don’t need them, making the application not check in the background so often.
It should go without saying, but we’ll say it anyway—you should remove the apps that you don’t need anymore, especially the ones that are draining your battery as determined from the android battery panel or task manager. Head into Settings –> Applications –> Manage Applications and then you can click the Uninstall button for an app.
Disable Home Screen Widgets You Don’t Need
If you’ve got loads of widgets that are pulling data from the web, that means they are likely pulling down data in the background all the time. You should try not to go overboard with these, or remove the ones you don’t actually need.
Disable Animated Wallpaper
Yeah, that sweet animated wallpaper doesn’t help your battery any. Get rid of it for a small extra battery savings.
Use APNDroid to Kill Your Entire Data Connection When You Don’t Need It
If you’re using a phone that’s on the AT&T or T-Mobile networks, you can use the APNDroid utility to kill your data connection entirely with a simple widget. It doesn’t work on Verizon phones in my testing. It’ll disable the data but still allow regular calls and SMS.
Keep the Battery from Getting Too Hot
One of the quickest ways to kill a battery is to leave it out in the sun—try and keep your phone somewhere that isn’t too hot whenever possible. You’ll end up needing to replace the battery a lot quicker if you don’t.
Additional Notes
There’s a number of other things you can do to extend your battery life a bit—one of which is to use a rooted phone and install the Autostarts utility, which you can use to keep applications from launching themselves automatically. Since this isn’t something you can do on a stock phone, we’re not covering how to do it here.
You can also use an application called Tasker to automate certain actions, like turning on or off the GPS or Wi-Fi when you launch a particular application, or scheduling a time of day to make sure that Wi-Fi is disabled. Lifehacker has a great guide to using Tasker to automate your phone, and they also explain how to use a configuration to scale back data usage at night.

As an addendum.
If you have an OLED device, apps with black backgrounds are much more power efficient. Therefore, switching your background wallpaper to something darker will help battery life.
Screen size is a major factor too, smaller screen, more power efficient.
I do 2 days with my S2, easily.
The list should get a better layout, but the provided information are good - thank you!
Another option for editing the syncing in applications are to go into your main settings, the accounts & sync. There it should list he apps that sync and you can change them from there rather than finding each app individually.
Mh, I only see a list of the connected accounts but no list of apps.

One issue I have now is with Sense 3 ported onto an original HTC Desire.
It has a bigger memory footprint than the stock Sense 1, and the memory cleanup function seems too aggressive, causing it to flush & reload too often, causing big CPU use.
Is there a way to tune memory `harvesting` to be less aggressive for specific apps in stock Gingerbread ?
You could try this app:
https://market.android.com/details?id=com.rs.autokiller
Yeah - I'm aware of the various task-killer 3rd party apps.
In my experience they often tend to lead to greater battery consumption as they over-ride the already pretty efficient gingerbread memory management.
I was hoping for a setting inbuilt to GB to just set residence priority higher on the single Sense task.

You can try out "autokiller memoery optimizer". It is a tool to change the value in the android underneath "low memory kill level". Maybe your current "low memory kill level" is too high (e.g. 250, means android will close your app when ur RAM is below 250). You can set it lower so android won't kill your apps too soon.
--------------------------------------------------------------------------------------------------------------------------
It fine tunes android systems inner memory manager to keep your device fast over time.
- As a side effect it also lowers battery consumption.
- At certain free memory level (e.g. 250mb), the android os will automatically close those apps not in use (according to original android os logic)

Thanks for this info. I have noticed that on my phone there is no direct way to close applications. Some application close when I use my back button but a lot just stay in memory. I would assume pressing the home button while an application is open will push it to the background. There seem to be no universal close button for applications other than using some application?

Share your tips!
I think automatic brightness is the best. If you go out during the day you won't be able to see anything on 0 brightness.
It's probably more convenient to just buy a second battery.
Good guide for those desperate for more battery life though.
Green Power is a much simpler alternative to Juice Defender and seems to work a lot better too!
Also there is no need for a task killer if you are running GB. Complete waste of time.
Task killer is much easier than GB internal app control. Save time, not waste time.
But remember FC task killer together thats all.
---------------------------------------------------------------------------------
Automatic brightness is good but not battery saving. The screen sensors have to work all the time and keep adjusting brightness. :/
Yes, we cant see anything under the sun. Thats the con.
1 more tip, uninstall useless aps
I have a Samsung Galaxy S running the FASTY ROM, and when I switched over to this ROM, I noticed I went from 6-hour battery life to 2-3 days battery life!
Go to every Apps that has Notification Interval in their setting, it updates in background although not display in the Accounts & Sync
Leave you phone off. Usually gets me unlimited power and run times.

That means you are good in saving battery.
There have been good tips mentioned but I would like to add that all those battery saver apps just do nothing. These kinds of apps are just ads while some of them like juice defender offer androidees a paid version (Ultimate, Pro etc) which is just another trick where it may be useful for lazy guys who can't turn wifi, bluetooth or other connections or apps off themselves!
I haven't actually tried any of ROMs which are told to be effective (like "undervolt") and on this position I must admit that manufacturers' ads for their mobile products are just lies as I have a SGS2 and whenever I start to play a HD game or connect via wifi it just starts to drain the battery times times more than the advertised battery life!
The only and reliable way of saving battery could be just using carefully: HD games for maximum 30-45 min and wifi connection for 2-3 hours. Playing movies or music could be run in a more span of time like 4-5 hours. Otherwise you will have no remaining for calling or necessary usages!

It's true, but other things also affect battery life (many of which the OP mentioned).
However, I just wanna add one thing which I'm sure many of you already know. But the reason I am mentioning it is because I witnessed this work on two Samsung Phones belonging to my friend and his wife: Galaxy Pro & Galaxy Mini (name of the phones, not my friends ).
At first, and on stock rom(not rooted) their battery life was horrible; and by horrible I mean less than 6 hours of usage (<24 hours idle).
I googled it and read somewhere, that fully recharging the phone then draining it completely (until it switches off itself) every day for a few days, the battery life will improve noticeably.
I told them about it; they tried it; and after only 3 days they started to notice the difference. They told me that it really made a difference. Now their battery life is 6-7 hours usage. 48 hours idle.
I know those numbers sound unrealistic but somehow it worked.
I have read this before, and it seems to be a common thing for battery life.
I haven't tried it on my DesireHD because I'm always hopping between different ROMs..
I hope this would be helpful for someone...
... my two cents Cheers!
Nice tips, thanks
Ways to maximize your battery life.
Generally when it comes to battery life I try to use those two tricks which work very well with ICS Roms.
I use ondemandx governor 122-1612MHz with suspend_freq=122MHz.
In order to achieve lowest power consumption in standby. You can tune manually Vdd at 122MHz =suspend_freq to the lowest value.
I also change in /system/buid.prop the value of ro.ril.disable.power.collapse to 0 instead of one by default in order to allow deeper sleep of the air interface.
Over all the type of ROM you are using, the age and capacity of your battery in your device also play a roll in the average time you get out of your device

i want to prevent apps to auto start to save battery and ram, which app should i use, grrenify or autorun manager or any other?
First, you need not concern yourself with free ram on an Android device. Android manages resources better by itself. As for the apps that launch on startup, you can got to menu>settings>apps and select the "running" tab to show you exactly what is really running. Then, the easiest way is to uninstall the app in question.
Automated task killers do nothing but cause more problems than they can potentially solve.
You might find this thread enlightening.

The task killer discussion gets old. I think there is risk of oversimplifying both sides. ie on one side people want to treat it like pc...not correct. On the other side people seem to imply any discussion of memory management considerations is irrelevant/rejected because "android will handle it all"....which is not always entirely correct either. The latter may be closer to the truth especially for new devices, but there is still room for middle ground. Not all programs are equal, some launch "services" which takes priority over other app processes. Too many of those services can eventually crowd out cache and slow your phone down. Maybe most people with newer phones will never get there, but there are still people with older phones (including the op for all we know) and also some folks with new phones who (if they listen to the oversimplifications) may get carried away on the number and type of apps they install over the life of their phone
---------- Post added at 12:47 AM ---------- Previous post was at 12:43 AM ----------
Even so, killing off those services is not the answer. If an older phone has too many running services so it taxes it's resources then it's either time to uninstall some or get a device that can handle it. If it's a problem with the app itself hogging resources, then let the developer know and find an alternative.
If you try to tow a boat with a bicycle, the answer isn't to throw away the boat's engine to make it lighter. Similarly, a task killer may make the phone's performance improve briefly, but over time it will make things worse. And it fixes nothing.
An app preventing another app from "auto-starting" is a task killer. Look at it this way: The phone boots up and runs it's processes. The auto-start blocker detects an app it doesn't want to run, so it kills it. Now, depending on what app it is, the phone may call for it again and thus running it later, which defeats the purpose of an auto-start killer, unless that app is a task killer which again kills said flagged app to keep it killed.
The way to properly manage an app you don't want to have enabled on the phone at bootup is to disable the app on the system manager (newer phones have it AFAIK), freeze the app via Titanium or similar apps, get into the app settings and disable certain features like auto-sync and set everything to manual.
However, the OP did not specify what phone and which apps. It may be apps which the phone requires to run at some level, like Maps (which several apps call for), or maybe the apps he is seeing are just RAM cached, which really don't matter at all.
Adjusting with app settings is preferred if you can, but does not always solve the problem (I referred to wakelock/battery drain problem with a certain version of Maps on my previous phone ... many people we having the same problem at the time and the only way to stop it was to block the app from starting as indicated in link below, or else to freeze it). Freezing has the disadvantage that you cannot run the program easily (requires you to launch TiBu to thaw the program). If you have blocked the program from autostarting, then it does not start at boot or other automatic time, but it remains available to manually launch the normal way (clicking the program icon). At that point (if it's a program like Maps), it will probably stay running until next reboot. It was my preferred solution when maps was giving me wakelocks and battery drain on my phone. Maps didn't run automatically on boot and never started until I manually started it. After that point I could live with the battery drain or reboot
Rom Toolbox Pro is a great app with many features and of course, there's an auto start manager that allows you to disable various receivers off the apps that start on boot. There's also a freeze/deep freeze feature as well. Great app
Ive got a SM-N770F/DS and I always have medium power saving mode on. I have also always had an issue with Google Maps not wanting to detect location after I turn the screen off. I assumed it was a google issue until I turned optimized power saving mode on today and Maps suddenly started reading my location and giving directions while the screen was off. Is it possible to disable the "prevent background location access" part of medium power saving mode? Long pressing my power saving settings doesnt give any options to do this, im thinking my only option is to root. Would rooting fix this? If so, does anyone know of some roms on here that would allow me to do this? I dont care about much else from the rom, I like the phone as is and this is the only issue I have with it
Do not toggled on any power management other than the power mode (optimized) and fast charging.
They screw up functionality and increase battery usage on my unrooted 10+ running on Pie.
In Developer options>standby apps all buckets should show as active otherwise power management is active. Android will manage apps well without any power management options turned on. Track down any remaining battery hogs on a per case basis and deal directly with them. Sometimes closing the window gets it done like with Brave. Others need to be dealt with by package disabler and/or Karma Firewall.
This may or may not help you.
Gmaps is crapware. Runs best on original factory load and is a parasitic drain wanting to constantly run in the backup from boot sucking up battery and bandwidth.
Unlike you my goal is to keep it from doing this
Also review Gmaps notification and other settings. It's a mess; buried settings galore.

I feel like I have experienced the opposite. I felt like my battery was draining faster with optimized on today (2nd pic) compared to the past few days with medium power saving on (first pic). Obviously more testing needs to be done to see. Going off of the pics I lost about 50% each day, so optimized seems to be worse for battery life but the reduced screen on time makes up for it in this scenario
Knowing how powerful ADB is, I was wondering if it would be possible to get a more granular control of battery saving features with ADB?? By example, I think it would be cool to limit processor speed while keeping tilt to wake gesture. Right now, battery saving mode work as an all or nothing mode. I used ADB to remove Samsung bloat and now I can comfortably make it through two days (not wearing it at night) but, it would be great to go even longer.
For now, I used developer mode to disable all animations, not sure how much of an impact it have but, it's better than nothing.
I just found this post here: https://forum.xda-developers.com/t/changing-cpu-governor-with-adb.4193163/ . It was intended for use on a Note 20 phone but it still look promising. I'll try it once I get back from travelling.
Clearly, power saving mode change cpu governor, among other things, on the watch. Now, I just need to get the same governor change without all the other things.
Any luck?
One has to assume that the engineers at Samsung are doing their research and setting things up to be as reasonably efficient as possible. Overdoing it (lowering CPU too much or for too long or at the wrong time, for example) could cause unexpected issues or instability.
