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.

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?

A common complaint among Android users is short battery life. As we all now, Google’s platform has numerous benefits, but state-of-the-art features and constantly being connected seem to come with one drawback: comparatively large battery consumption.
I don’t suggest that you should stop taking advantage of the things that make Android great, such as streaming music players that allow you to walk around with millions of songs in your pocket, location-aware apps, background updates or all the wireless options. Still, if you’re frustrated by how often you need to connect your charger, it’s good to know what types of apps and activities that eat the most battery, so you can make an active decision whether or not it’s worth the extra juice. Use the GPS Wisely
The GPS uses the battery like there’s no tomorrow. Location-aware software is one of Android’s many fortes, but they can be real battery drainers. The Power control widget is useful for switching the GPS on and off, and you should keep an eye on your notification bar: an icon will appear whenever the GPS is activated.
Turn off Bluetooth When You’re Not Using It
Perhaps an obvious tip, but it’s best to disable Bluetooth whenever you’re not actually using it. The quickest way to switch Bluetooth off and on is via a widget on your homescreen.
Disable Wireless Network Positioning
When your device learns your location via wireless network triangulation, it requires less battery than if it had used the GPS. But using both methods simultaneously will of course use the most power. The GPS can handle location tasks by itself, albeit a bit slower. Also, wireless network positioning is used to gather anonymous Google location data in the background, which will drain the battery further. You can turn it off from Settings > Location > Use wireless networks.
Switch off Wi-Fi, or Keep it Always On
If you’re close to a reliable WLAN during the better part of the day, having Wi-Fi always turned on may be favorable from a battery point of view, since the Wi-Fi radio uses less battery than the 3G radio. And when Wi-Fi is on, 3G is off. You can confirm Wi-Fi always stays on by going to Settings > Wireless networks > Wi-Fi Settings. Press the Menu button, tap on Advanced, Wi-Fi sleep policy and select the Never option.
On the other hand, if you’re not close to a strong Wi-Fi signal for extended periods of time, disable Wi-Fi from a homescreen widget or from Settings > Wireless networks > Wi-Fi. Disable Always-On Mobile Data
The Always-On Mobile Data option is on by default, and can be disabled from Settings > Wireless & networks > Mobile networks > Enable always-on mobile data. It allows your phone to be connected non-stop, but does it need to be? I have disabled the setting, and I still get push Gmail and even Google Talk seems to perform as usual, as well as the few apps I have that use automatic updates. However, if you have a lot of apps that regularly connect to the Internet, disabling this option may actually be a bad idea, since turning the data connection on and off will require more energy than simply having it on all the time.
Kill 3G if Your Phone Often Struggles to Find It
When your Android attempts to decide which signal to lock on to, it strains your battery. If your phone often switches between GSM and 3G in your area, it can be preferable to simply disable 3G altogether, and hence abolishing the need for your phone to try and find a suitable network. Go to Settings > Wireless & networks > Mobile networks > Network mode > GSM only. Use a Quick Screen Timeout
After a certain time of inactivity, your screen is automatically turned off, and that’s the Screen Timeout. To use such a low value as 15 seconds can be annoying, but one minute is on the other hand likely too long. I use 30 seconds. You can alter this option from Settings > Screen & display > Screen timeout. Turn Down the Screen Brightness
Android’s Automatic brightness (Settings > Screen & display > Brightness) setting is recommended. If your phone doesn’t have this option, set a reasonable value at roughly 30 % and see if that suits you.
Live Wallpapers Will Use More Power than a Static Background
Oh yes, live wallpapers can be awesome. But they will obviously use precious battery juice, albeit evidently not as much as one could think, talking the eye-candy into consideration and what they can do. Have an AMOLED Display? A Dark Wallpaper Will Spare the Battery
When having dark backgrounds, phones with AMOLED display will use less power, because each pixel on OLED screens is photoemissive and will actually generate its own light. Since there’s no need for a backlight, the pixel can essentially turn off its light source and go total black. As a result, you can save a teeny-weeny bit of energy by having a dark or black background on AMOLED screens. Use Widgets Wisely
A few days ago, we mentioned 10 cool homescreen widgets, and it’s great that Android supports them. Most widgets will only have a negligible effect on your battery life, but those that automatically pull info from the interwebs can be power hogs. Use Reasonable Intervals for Automatic Updates
I personally don’t need to have automatic updates on my phone, except for emails that I want to be notified of the moment they arrive. I prefer launching the apps at my convenience and see what’s new. Most applications that connect to the Internet have an option to update upon launch, and that’s all I need. By lowering the update intervals, or by even turning them off completely, you can definitely make your battery last longer. I recommend that you reduce them to your own minimum values.
If you have an Android phone with HTC Sense, you can make sure the HTC Mail Client, the HTC Weather App, Facebook, Flickr, Stocks and Twitter update themselves as often as you want them to. This is mainly done from Settings > Accounts & sync. It’s also a good idea to look over third-party apps that grab data from the Internet, particularly the official Facebook app and the various Twitter apps, since they usually have background updates on by default.
Streaming Apps Will Use a Lot of Battery
In a recent Droid vs Droid special, Andrew did a rundown of music streaming apps, and I certainly don’t think you should avoid this type of application on your phone. But bear in mind that software that stream audio and similar apps will use plenty of power. Learn What’s Been Drinking the Juice
Unless you have the doubtful pleasure of still running Cupcake, you can check out a built-in Android feature that tells you precisely how much your apps use the battery. You can then start using battery drainers less often, or simply uninstall them. Go to Settings > About phone > Battery > Battery use and press the items in the list for further info. You can also use JuicePlotter to analyze usage patterns.
I have gotten good results by making the tweaks and changes above, and I hope you will too. Do you know of any more tricks that can make our dear Android stay on his feet a bit longer before it needs to be charged? In case you don’t want to keep all this in mind, an app such as JuiceDefender is a good option
Use setcpu app or any other one that involves controlling CPU and set a profile to make your CPU very low(this one helps a lot but your gonna notice a little lag when your unlocking your screen)

And do not use task killer. I think it's one of the reason that drain your battery quickly
all pretty good tips.
I have a problem on my phone where the cpu will not enter deep sleep mode but im sure its my fault. It says the android system is taking alot of battery in battery usage.
I would highly suggest staying away from any task killing related software, they generally aren't good for Android and can lead to problems down the road. There's an application called Juice Defender on the Google Play store and it's been working for me. I can easily turn off battery hogs like GPS and 3G while your device is inactive.
Closed, redundant thread
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.

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?
Hi guys
I'm a BlackBerry user of ten years and have recently moved over to Android (with some regret).
I know Android is great for customising, so my quest now is to find out how to control individual apps from running too much data - I know of the "Restrict Background Data" option, but is there a way to be more granular and control which apps use data on Wi-Fi and on Mobile Data?
And on that, to reduce battery consumption, is there a way to control the interval frequency with which apps synchronise? For example, Sunrise, Gmail, Inbox, Google Keep - if they're all polling and synchronising regularly, I'm sure that uses up my data and my battery a lot faster. Is there a way to tell them "only poll manually" etc.?
Hi, you can go to settings>battery turn on the battery saver and see what apps or features consumes the most of your battery, analyse them and take action according to that by removing, synchronizing or stop particular apps.
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.
