Let us not imagine a smartphone without battery. Battery is most important part of a smartphone. There is a few cause to drain battery quickly. Like as big LCD display and luscious AMOLED display, and background apps obviously drain your battery quickly. You can do something to make battery for last longer. Let’s see that how to increase battery on your android smartphone.
how save battery life
How android batteries work:
Have you heard that most smartphones have a lithium-polymer either or lithium-ion battery. Both of actually lithium-ion though, and as like, do not have a 'memory', which means that you can charge them from any level – you don't have to fully discharge it before charging it up – and you don't have to charge them all the way to 100 percent.
In fact, lithium-polymer either or lithium-ion types of batteries affected by low voltage problems, so it's actually better to partially charge it (say, from 20 percent to 90 percent) than to fully charge and fully drain tit. Just explore that is it work for you and you can easily increase battery on your Android smartphone.

Black wallpaper can increase battery:
If your phone has an AMOLED display (like as Samsung devices), use a dark-colored wallpaper for background . AMOLED screens only illuminate the colored pixels that’s why Black wallpaper can increase battery life. Black pixels are unlit, so that less power is needed to light them up.
Doze:
With the entrance of Marshmallow came a new feature called Doze, which is helps you get to reduce drain of your battery. , Doze is the most noticeable addition for android Marshmallow. It is allow default and typically permit your device to enter hibernation mode when it has been lock or unused for a long period of time.
Update your apps into latest version:
Keep update your apps with the latest version. The developers constantly update apps for battery and memory optimization. Keeping your apps updated also means you have the best optimizations available
Using Greenify apps:
There are many Android apps that claim that they optimize performance and increase battery life, Greenify is one of them and it’s actually works by preventing them from operating in the background. , which reduces their impact on the system Greenify stops this by sending those apps into hibernation and saving battery life while improving performance.
Reduce auto-brightness:
The screen is a biggest battery drainer. This is one of the best ways to increase your battery life to use auto-brightness manually to a level that is low but comfortable your eyes. And do not use display as auto-brightness mode.
Turn off vibrate and haptic feedback : For save battery turn-off your vibration alerts for incoming call, and turn-of your keyboard vibration and touchpad sound.
Use 'Do Not Disturb' or 'sleep' schedule :
when you are In a meeting , set your device to not ring, vibrate or connect to the internet when you are sleeping you can enable blocking mode to switch off Wi-Fi and mobile data when you don't need them.
For this purpose many phones have a Do Not Disturb setting.
For example you can use airplane mode.
Trun-off unnecessary service:
Whenever you don't need them turn off, Wi-Fi , GPS, Bluetooth, NFC and mobile data,Turning off location. It’s will increase battery on your Android smartphone.
Explore the battery saving features on your phone:
At first Find out the battery saving option in your smartphone and Trun on your bettery saving mode in your android smartphone when you are out of home and not use the phone.
Turn off auto-sync trap:
If you do not need google account update in every 30 minutes, tap into setting to turn-off google account turnoff auto sync and for these app you do not need update. For example email, Facebook, twitter, reddit Instagram etc. just sync when you actually use the app.
I miss something’s? What you have any idea about battery saving tips? Tell me about them in the comments.
I don't, and will never use gapps or any google's apps.
I am experiencing a high and crazy performance using ntfs as androed installation.
I will never burn my money in ext2/3/4 or any ext device.
I will never pay absurds for unrooted phones to rooting only to purge gapps and gogle apps or any other kind of damned apps that stays cooking battery.
My next device, needs be like this screenshot, with ntfs, rooteable, rom choices, or DEATH!
I hate androids.
This is why i preffer write Androed

Hey guys,
So after many months with the XT720 and alot of flashing and trying to get the most out of my battery, i've come up with a few conclusions about battery life in general and how to extend it. I thought I'd share here. This is mostly aimed at people who are new to android and have not experimented like some of the more advanced users we have on this forum. Hope you find this helpful and please feel free to make additions.
General Battery Info
The XT720 was my first android phone, and I came from a long line of typical nokia phones whose batteries would last for ages. I had no idea the kind of power an android device would use. When I started out using it, i was surprised at how quickly the battery would die. You'd think with advancing software we'd have better batteries but sadly batteries are lagging behind in technology. Generally speaking you can expect the following battery life from your XT720.
Heavy use: 10-14 hours
Moderate use: 16-20 hours
Light use: 1 day - 1 day 12 hrs.
Note: New batteries improve with each charge cycle. It is recommended to go through a few complete charge cycles when you buy a new phone. After that, complete discharges are not recommended and its smart to start charging your phone when it hits the 20-25% mark.
How to improve battery life
1: Battery Calibration
If you've ever flashed a new ROM, you must have noticed a sharp decline in battery performance. This is partly due to old battery statistics left behind from your old ROM. Android is a smart OS and collects information over time. The more you use it, the more accurate it gets. In the same way it collects information from your battery usage and reports your battery percentages according to that. When you flash a new ROM, sometimes android thinks that your battery is 100% when its really lower than that and that causes relative reduced battery performance. To deal with that it is recommended that you use a nifty free app called Battery Calibration from the android market. What this does it removes the old battery stats and allows your new ROM to create its own battery stats. Charge your battery to full, use the battery calibration. Drain once till phone turns off by itself and charge to full again. You will notice a sharp increase in battery life.
2. Battery Managment
We all know that android has its own battery management built in but it usually doesnt give complete information about the phone. For that you need to dive deeper into the settings. Usually if you experience battery drain its because of a rogue app and believe it or not some common apps you wont think off drain unnecessary battery. To see your complete Battery Stats input this code into the dialer.
Code:
*#*#4636#*#*
This will take you to a bunch of options. What you're interested in is Battery History. When you tap that it will show you two drop down menu's.
1) Other Usage
2) Since last unplugged
Other usage shows you how long your phone has been running and how long it has been asleep. Also shows you how long your wifi has been on and running and how long your screen has been on. It is important to see how long your phone has been running. For example if your phone has an uptime of 20 hours and its been running 5 hours out of that. Your run time is 25%. Which is very good. Sometimes an app can run even when your phone screen is off. This will represent a longer run time even when you have your phone lying on a desk or something. See this setting and correlate with the amount you have used your phone. Does it seem normal? If no then use the first drop down menu and select
Partial Wake:
Partial wake is basically, any app which takes your phone out of sleep mode to use the CPU even when youre screen is off. These are apps which need to sync or use the phone resources. In this you will see a list of apps and how much they have caused a partial wake lock. See anything unsual? For me one app that caused unsual drainage was latitute. Yes, i had simply signed into it and i didnt know it was updating my location every 5 minutes. Extreme battery drain for me even when my phone was idle. See which app was draining your battery and either tweak the settings or remove altogether.
GPS, Sensors, CPU:
You can also see these in the first drop down menu. Certain apps like screeble use the sensors alot, and hence cause drain. Obviously games, camera, will stress the CPU. See if anything is causing drain in that and adjust accordingly.
Miscellaneous Information
After you have dealt with rogue apps that you don't use that drain youre battery your battery life will depend on how you use your phone. But hopefull these tips will help you with increasing your battery life. I do have some more information on different settings and supposed battery saving applications.
Autosync: When you enable auto sync, you allow google and other accounts to sync on a regular basis. This is important for people who need to use push email etc. It does not drain battery IF you tweak what you need synced. In google for example you can have your contacts, calendar, google+, google reader, gmail all to sync by default. If you just need email, please untick the rest. This will help you save battery life. Increase your update times for facebook and google+ if you dont recieve many updates all the time or turn them off altogether. If you have many services syncing at the same time you will get battery drain.
Wifi Sleep Policy: This is sort of a hidden menu. If you go into wireless & networks >> Wifi settings >> settings key >> advanced >> wifi sleep policy. This has three settings. Never close down wifi, never close when charging, or close with screen off. If you choose never your wifi will always be on, which will in turn crunch the **** out of your battery. If you use it off with screen off, remember it takes about 5 minutes to turn the wifi off. I personally use the never with plugged in. Its an intermediate. So when im plugged in wifi always stays on and when im not it follows the screen off protocol.
Wifi Vs Mobile Data: Having mobile data on all the time, does not drain battery. The only time the battery gets drained is when the data connection is active i.e you have many apps on autosync youll see your battery going down. If you arent doing anything and your phone is connected to Edge or 3G your battery will drain regularly. 2G networks drain less than 3G keep that in mind. If you are actively using your connection, wifi will take less battery because speeds are faster and you will be using it for a little time. Also your signal strength has alot of effect on battery. If you have crappy 3G signals your radio will actively be searching for a connection the same goes for wifi. That is important to keep in mind.
Control Background data: By selecting this option you can allow or disallow apps to connect to data without any permission. Some apps require this like the android market. If you uncheck this apps wont be able to sync automatically in the background.
Milestone Overclocking: This is fairly obvious. The higher you overclock with higher vsel the more battery drain you will have. Some use set cpu with profiles but I found that if i set the setcpu too low while idle It takes time for the cpu to charge up when i recieve a call or turn the screen on. Ringtones lag etc etc. I let android do my CPU management and its fine. and comfortable setting would be 850 MHZ, 56 vsel but you can change according to your phone usage.
Juice Defender/ Screebl / Task killers:
In my personal experience with juice defender ultimate I found that with the above precautions juice defender didnt make much of a difference and actually used more battery. First off theres an extra process going on in the back. Second activating and deactivating the connection everytime the screen goes off uses more juice because your radio has to search for the signal hundreds of times as compared to not having it in the first place. Screebl is good if you dont want your screen to annoyingly turn off while youre doing something but it surely doesnt save battery life. Task killers are a no no for android. They kill tasks which start up anyways, its better to use autokiller memory optimizer which tweaks androids internal memory settings and allows for more free ram without killing processes without reason.
System Apps:
Some system apps run uselessly in the background specially with stock ROM's this is called bloatware. Remove all unused system apps with titanium backup to stop them from running in the background for no reason at all.
A final word
Finally after all this tweaking, just use your phone as normal. Dont worry about the battery all the time checking how much its drained, itll mess your head up and make you enjoy your phone less. Battery temperature also changes battery life. Keep your phone out of the sun or in hot places.
Thanks, good article.
Very detailed and useful
Sent from my Milestone XT720 using XDA App
Thanks for this interessting article!
Could you make a list of the bloatware that can be safely removed?
I figured this would just list all the usual stuff I've heard. I'm glad to say I was wrong! A bunch of useful info here I now plan to put to use. Many thanks
Might want to mention the display being the biggest drain of battery on this phone. Setting it to automatic brightness or lower will increase battery life. I love the screen at full brightness so I don't really follow that, but for those looking to squeeze some extra time and don't mind less brightness...
Thanks guys, glad you people found it useful.

Yes! Can't believe I missed that one out. In the start id use the lowest brightness setting, which would be fine indoors. But outside it was impossible to see the phone because of its insanely reflective glass. Since we have an ambient light sensor I use it on automatic and it does a good job. Full bright strains my eyes abit thats why I dont keep it on full bright So for people really wanting to save the juice you can keep your brightness on the lowest level. Also when you take the phone out of your pocket and use it, its better to put the phone to sleep with the power button than let it timeout by itself. Those 10-15 seconds for each time you use phone count towards many minutes of unused display time in the end and does make a difference.
This is a very gd post with lots o useful info!! ok i have a qn, is using the phone a lot while the charging good for the battery? And if u let the battery charge even though its already 100 percent for an hour good? srry if it is noob qn...

1. Using your phone while charging does not affect your battery life, and is neither good nor bad. It is perfectly normal to use your phone while charging and is sometimes recommended while doing battery intensive tasks for example navigating while driving, wifi tethering, playing memory intensive games and finally outputing video through HDMI.
2. Overcharging was a phenomenom is older lithium ion battery. New batteries have bypass circuits. So when your phone reaches complete charge, it does not charge any further. So you should not be worried about overcharging your XT720.
Hope this helps.
Excelent article and good quality info. Thanks and best regards!
awesome article! Great information. Thanks a lot for putting that together. I have already started using a few of the tips mentioned.

Wake lock Activities:
You can easily find out yourself, which app or hardware is consuming a lot of memory and power.
1 Kernel Wake locks,
2 Partial Wake lock,
3 CPU States
Kernel wake locks: These are low level/hardware wake locks from the kernel. We can only reduce these by modifying the kernel or reducing the usage of a certain feature of the kernel. By researching these we can improve the battery consumption and performance of the Kernel.
Partial wake locks: These are wake locks from apps. These can be reduced by uninstalling or disabling features in software. We can talk about those here too, though it shouldn't be the focus as the answer will be "Uninstall/Disable feature X and talk to the app author". Preferably we should talk about partial wake locks from Google services like maps and latitude.
CPU: The numbers reflect the percentage of the time since the last screen update that the CPU spent in each state. The output for this line requires past history, and it is not shown on the first display that is produced.
Other Weak locks: It is important you find out where your major battery consumption is, Deep Sleep, Awake, Screen On, and Wi-Fi on, Wi-Fi running, Data Connection, or Screen Dark.
Process: You can find out which application consumes the most Battery juice. This is a collection of interrelated work tasks and an initiated response to an event that achieves a specific result for the user of the process.
Networks: This will help you to figure out what is happening on your network connection, what the battery power consumption is, the interval etc...
Others depend on the usage of the application and etc...

Please try the application and give a feedback...
woooow, what are you doing with the system tweak dude? in order to save more juice, i tweak my CPU Max Freq UV to 960 MHZ and doin some tweaks on the CPU Gov. Of course by doing this i sacrifice the performance. But then i installed your system tweaks and then boom! all of the scrolling home screen performance become very fast? this including the three navigation bar delay-in-pressing and application opening also now become fast.
I corious, then i open my cpu governor ...maybe you enter an init.d script on it to change the value, but i see there the value is still the same with my "battery saving mode". then i open the animation and scrolling speed, also still the same setting.
is this tweak really increase performance without sacrifice more battery?
Thanks
I will compare with DU battery. ^^
All the CPU/kernel/system tweaks are available only in the pro version. Can't you make them available in the free version even for a while to test?

Hello Sir! Can Anyone Give Me Any Solution To Increase Moto G 2015 Battery Life?
Sorry For Bad English
Bro Battery Life totally depends on user's usage ... But still u r looking for methods to improve ur battery life here is your answer suggested by Motorola:-
Tips to extend the battery life - Moto G 3rd Generation
The battery life for a device may vary day to day depending on usage. Navigating, playing games, browsing the Web, making calls, and sending text messages all drain the battery of the device.
Try some of the following tips to maximize the battery life:
Charge the device properly
Charge each night so you start the day fully charged and ready to go.
Ensure you are charging the device correctly.
Restart the phone at least once a week this will reset the Battery cycle.
Adjust connection settings:-
Turn off Wi-Fi. Bluetooth, and GPS when you are not using them.
Close apps that use GPS when you no longer need them. Swipe down from the Notification Bar to see if you have active navigation applications that offer an option to quit or exit.
Change Location Settings to use Battery Saving mode:
Settings>Touch Location > Battery saving.
Be aware of network availability
If you are in an area with low or no signal, the phone uses more power attempting connect to the weak signal. If possible, switch the phone into Airplane Mode to prevent excess battery drain.
Use Wi-Fi when possible. Data over Wi-Fi uses less battery life than data over cellular networks.
Adjust display settings:-
When setting the phone down after use, quickly press the Power key to turn the display off.
Lower the screen brightness when possible:
Change the screen timeout to less than 1 minute.
Settings>Touch Display>Touch Sleep.
Manage applications
Close applications you are no longer using. Select Recent (the square icon) in the lower right, then touch the X in the upper right hand corner.
Be aware of how much battery is consumed by running certain applications. Apps that use a lot of wireless data, such as streaming video or music, navigation, and maps, will drain the battery more quickly because of the data being transferred.
Find out what application or feature uses the most battery life: Swipe down from the top of the screen, touch the Quick Settings Image icon, touch the Battery icon.
Apps that update frequently, like social media or email, also consume battery power more frequently. Some live wallpapers and widgets may also consume battery life. Limit use of these apps when battery life is a concern......

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.
