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.

Thanks, very usefull information
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.

Nice clear guide
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?

thank you for your information,,, i will try it and hope it can solve my phone with battery problem,,,
Hi friends !!! i have written this thread in order to tell you how to get better battery life for your android phone . this always works for me !!!!
1. Find out where the power's going
The first step in prolonging your battery life is to find out which apps and components are using the power.
Press the Menu key, tap Settings, scroll to the bottom of the Settings menu and tap About Phone. Tap Battery Use in this menu to see what's eating the charge.
The chart at the top shows how long the phone's been off the charger and plots the rate of power drain over time. Tap any item in this menu for details and, if available, suggestions on how to cut its power use.
2. Use the screen wisely
For almost all users, the display is the biggest single drain on the battery. From the Settings menu tap Display to see the options. Tap Screen Timeout and set a short timeout to ensure that the screen goes dark when you aren't actively using the phone.
The Display menu has two options for controlling brightness; tap Brightness to select a constant screen brightness or to enable automatic adjustment to suit the ambient light. Tick 'Power saving mode' to have the brightness also vary to suit the image on the screen. You can improve things further by tapping the power button whenever you're finished with the phone, which instantly turns off the screen.
3. Turn off what you're not using
Radio interfaces help to make smart phones truly smart but they also suck up the battery's power. Drag the Notification bar down from the top of the screen to quickly toggle Wi-Fi, Bluetooth and GPS.
Leave Bluetooth and Wi-Fi off unless you're actively using them.
GPS can often stay off too, but try to turn it on a few minutes before you'll actually need it -- on many phones this speeds up getting an initial position, meaning less time spent faffing with the screen and burning even more battery power.
4. Running apps drain the battery
It's easy to use the Home button to get from an app back to the Home screen, but doing so leaves the app running in the background. That may be what you want, but if not, the app will be sipping needlessly away at the battery. Quit apps properly by pressing Back until you return to the Home screen.
If you've quit all applications but something still seems to be draining the battery, enter the Settings menu, choose Applications and tap Manage Applications. Tap Running to list all the running apps and services -- tap an item for the option to stop it. Restart the phone to close all manually-started apps in one go.
5. Watch out for widgets
Widgets can be useful, but many -- such as news tickers or weather forecasters -- need processing time and data downloads to stay updated.
Resist the urge to festoon your home screens with widgets -- create application shortcuts instead and only run them when you need them.
While we're on the subject, Android's live wallpapers might look cool, but they're a constant drain on resources. If power's an issue, swap them for a decent gallery picture.
6. Email can wait
If something's urgent, people normally call, so it's safe to save power by checking for email less often.
Start Android's Email app and tap an account, then press the Menu key, tap More and choose Account settings. Tap Email Check Frequency and choose Every Hour, then repeat for any other mail accounts.
You can do the same in many social media applications, such as TweetDeck.
7. Go easy on video and games
Android phones make great radios, music or movie players, but video playback is one of the biggest possible drains on a phone's battery.
It might sound obvious, but don't get carried away with iPlayer on the morning commute if you need your phone to last until you get home again.
The same goes for Angry Birds, Stair Dismount or any other game -- levelling up can leave you powerless.
8. Try a third-party power app
The Android system does many things to manage power use but there are third-party apps that do more. JuiceDefender is one of the best examples -- there's a free version in Android Market.
JuiceDefender works automatically to keep power use down and you can tailor the settings to be more aggressive if needed.
The Plus and Ultimate versions add more features, but check first that the free version works on your phone.
9. In an emergency
With 15 per cent charge remaining, Android's low battery warning pops up and it's time for drastic action. Immediately head for the notifications bar and turn off as many options as possible.
With that done, hold in the power button and turn off Data network mode. Now exit all non-essential apps, return to the Home screen and turn the screen off.
From this point onwards, it's best to treat your smart phone as just a phone. Leave it alone unless there's a call or text to answer and you'll save enough power for when you really need it.
10. Never pass up the opportunity to charge
You never know when you might need a three-hour phone call or a gaming marathon, so it pays to top up your battery when you can. Invest in a USB adaptor for the car and buy a Micro-B USB cable that you can use to grab a top-up from any spare USB port. Obviously, perhaps, charging is quicker with the phone off.
If using your handset as a modem, tether it with USB rather than creating a wireless access point so you can charge at the same time. If your laptop supports it, configure its USB ports to provide power even when it's switched off so you can boost your phone.
Finally, if even all of these tips can't get your phone through the day, buy a second battery for backup .
I am sure this thread helped you . do give me your feedback .
regards ,
Hussain .
btu simply using n app like the easy task killer or the advanced task killer can simplify the work.
just a suggestion.
As the title asks, what is it? I know that turning off the screen with power button is not sleeping. I believe it is the state when it takes more than a second (lag) to unlock the screen. This means that the phone was in sleep state and I woke it up. But the question remains, that what is it? How and when is it activated? What happens when the phone is sleeping? Effect on battery (I believe it's positive)? The notifications like sms and call? Is only the screen asleep or are the other functions sleeping as well? Final question, Can I activate the sleep mode with the help of an application if it helps save the battery?
Note that I don't want to use battery saver apps because I don't want anything on my phone to stop. I paid for the whole phone, "including" gps, wifi and things like that. Smartphones are for us, we are not for smartphones.

Technically; sleep mode starts the moment the screen is switched off. With the exception of applications which can prevent the phone from fully 'sleeping'. A good and obvious example is the music application which keeps the phone awake in order to play music.
There's really nothing special about sleep mode except that the phone will execute a lot more tasks together but less frequently in order to save power, so you're still able to receive all messages, emails, calls and all notifications (from apps). Applications can also be informed about the change in power state (awake to sleep and sleep to awake) and therefore change the way they behave.
The amount of sleep time the phone gets is dependent on the apps you have installed and the amount of emails, calls and other notifications you get. There isn't a way to enable 'sleep mode' with an application as it would make little difference if your display is on. Your display is the main cause of power consumption, as is true with all smartphones.
Battery Saver apps are dangerous, by killing apps they have a negative impact on the phone. If the application is needed, the phone will restart it and add to the CPU cycles. The same goes with memory freeing apps. GPS/Bluetooth/WiFi are there for when you need them. Keeping them on when they're not needed is a waste of the phone's resources. As the more CPU cycles they use, the more power they consume.

That's a good explanation
I have read about term "deep sleep" while searching for this, but the explanations on the internet are not clear to me. I have understood a part of it, that this state comes when phone is at rest for too long. The phone pauses apps and their processes, except those who are downloading e.g games and only does basic tasks such as incoming communications (message, call etc.) and sync. Again, I could not find answer to when it state/mode starts.
About GPS/Bluetooth/WiFi: I said this because I had seen people talking about how they have to force otherwise unnecessary restrictions on them and thus have to worry too much to save their batteries. This is what I don't like. Technology is made to facilitate people and to make their lives easy, that's what I believe. On the other hand, I always keep bluetooth off because I need it very rarely. Well, you may have other preferences but I have to keep gps on in order to geo tag photos and to make it ready whenever I open maps etc. Wifi according to me is life blood of smartphones. So I can't live without it either.
When I had Nokia 5800 I had to turn off auto rotate because its menu took time to refresh if I turned the phone by mistake. That was the time when I came to know how bad it feels to go through the settings to turn it on when I need it urgently.
Today's Android phones pack big bright screens and high-end features that suck plenty of power; here's how to squeeze the most juice out of your battery.
1. See what's sucking the most juice. Navigate to Settings > Battery to see an organized breakdown of what's consuming your phone's battery. Applications and features will display in a descending list of battery hogs. If you see an application you barely use or a feature you never use, you'll want to uninstall the app or turn off the feature.
2. Reduce email, Twitter, and Facebook polling. Set your various messaging apps to "manual" for the polling or refresh frequency, just as a test, and you'll instantly extend your device's battery life by a significant amount. Once you see what a difference that makes, try re-enabling just the most important ones, and possibly reducing their polling frequency in the process.
3. Turn unnecessary hardware radios off. It's great that today's phones have LTE, NFC, GPS, Wi-Fi, and Bluetooth, but do you really need all five activated 24 hours per day? Android keeps location-based apps resident in the background, and the constant drain on your battery will become noticeable, fast. If your phone has a power control widget, you can use it to quickly turn on/off GPS (the largest power drain), NFC, Wi-Fi, Bluetooth, and LTE. On stock Android, swipe down to bring up the Notification bar, and then tap the icon on the top right corner.
4. Use the extra power saving mode if you have it. The aforementioned Galaxy S5 and HTC One (M8) both have Ultra Power Saving and Extreme Power Saving modes, respectively, that limits the phone to texting, phone calls, Web browsing, and Facebook. This can squeeze extra hours or even a day of standby time out of just a few remaining percentage points of battery.
5. Trim apps running in the background. From Settings > Apps, swipe to the left; you'll see a list of apps that are currently running. Tap on each one to see what they're for; you can stop any apps that you don't need running in the background all of the time.
6. Dump unnecessary home screen widgets and live wallpaper. Just because they're sitting on the home screen, seemingly inactive, doesn't mean they're not consuming power.
7. Turn down the brightness and turn off Automatic Brightness. It's probably obvious at this point, but you'll be surprised by how much this one alone helps to improve battery life.
8. Update your apps. Applications often get updated to use less battery power, so you should make sure your apps are up to date. Even if you configured the phone for automatic updates, some apps still require that you manually install updates. Check for app updates in Google Play by hitting the menu key and going to My Apps.
9. Keep an eye on signal strength. If you're in an area with poor cellular coverage, the phone will work harder to latch onto a strong-enough signal. This has an adverse effect on battery life.
10. Check the reviews. We conduct battery life tests on every single Android phone we review. Unsurprisingly, the results vary widely between handsets, even on the same network. When choosing a phone, make sure that real world talk time is sufficient.
11. Buy a battery case or larger extended battery.

Thanks, great tips!
I had a question, does enabling "double tap to wake" consume more battery because the phone is always on the lookout for a touch or something even when the screen is off?
mod edit - link removed How to improve iPhone battery life in iOS 11[/URL]
In a recent tech*poll, 70% of readers reported that*battery life was worse with iOS 11. In the same article, we noted that security research firm Wandera shared data that it took iOS 11 an average of 96 minutes to drain iPhones and iPads completely, while iOS 10 took 240 minutes.*While more that a 50% drop in battery life sounds terrible, there are a few things to keep in mind.
if you want to get right to tweaking your iPhone for better battery life, head below.
How to improve battery life
1. Understand your battery usage
Head to*Settings*→*Battery*to check out the details of your battery usage.*Last 24 Hours*will be the default for showing what apps are using the most energy.*Tapping the clock icon on the right hand side gives you a detailed breakdown of how much time was spent on screen and in the background for each app.
Also take a look at*battery life suggestions just above battery usage. This will give you quick, actionable ways to reduce battery drain. Now you’re*in a better position to be more efficient with usage, along with having an idea of more settings to adjust as we keep going here.
2.*Adjust Auto-lock and Screen Brightness
If you notice Home & Lock Screen usage on your battery usage higher than you’d expect, double-check that setting. If you can tolerate it, 30 seconds will help you preserve the most battery life. Especially with most of Apple’s iPhones supporting raise to wake, 30 seconds is usually worth it.*Lowering your screen brightness will also help with battery life, but this will likely come down to personal preference.
Navigate to*Settings*→*Display & Brightness → Auto-Lock.
3. Background App Refresh
Low Power Mode turns off background app refresh across the board, but you can customize which apps use this feature for a more convenient experience as well as improved battery life.*You can also opt to only use background app refresh on Wi-Fi in addition to Wi-Fi and Cellular or turning the feature off. However, most users will find leaving Wi-Fi and Cellular on while customizing which apps are used for background app refresh to be the best fit.
Head to*Settings*→*General →*Background App Refresh.
4. Low Power Mode
Low Power Mode isn’t new in iOS 11, but it’s a really useful feature to stretch your battery life when needed. The feature works by suspending mail fetch, background app refresh, auto downloads, and more. This isn’t a ‘use every day’ type of feature (hopefully), but is handy in a pinch.*You can turn on Low Power mode under*Settings*→*Battery.*However, it’s really useful to have quick access to Low Power Mode by adding it to iOS 11’s redesigned Control Center.
Navigate to*Settings→*Control Center → Customize Controls,*then tap green button with a plus sign*next to*Low Power Mode.
5. Push and Fetch
Taking a look at your push and fetch settings is also worthwhile. Navigate to*Settings*→*Accounts & Passwords*→*Fetch New Data. One possible approach is to leave your primary account(s) as push to receive new mail asap, and turn secondary/non-crticial accounts to fetch every 30 minutes or hour.
6. Location Services
Taking a look at your location services settings is another way to be more efficient with battery life (and cellular data usage). Head to*Settings*→*Privacy →*Location Services*to update the privileges for your apps.
Watch out for any apps that ask to*Always*use your location and switch to*While Using*or*Never.
