Tricks used to extend battery life in Android Phones

Share with others tricks used to extend battery life.

Tricks known to me:

1.Reduce your Screen Brightness
Display uses about 5-80% of battery usually. Reducing the brightness helps to increase the battery life a lot. To do so goto Settings->Display->Brightness
- Automatic brightness is good but lead to higher consumption of battery. Close brightness automatic and set brightness low.

2.Disable Wi-Fi, Bluetooth, GPS, NFC
Even though Wi-Fi, GPS and Bluetooth are designed for low-power consumption, they drain the battery. Most of the 2012 android devices have a unique feature known as NFC (Near Field Communion) such as i9070p. This feature enables a sensor field around the handset and is used for sharing. This also drains the battery unnecessarily. So it’s better to turn off the Wi-Fi, Bluetooth and NFCs when it’s not in use.
- Deactivate Wi-Fi when not needed
- If you do not use the Bluetooth function, disable it.
- If you do not use the NFC function, disable it.
- If you do not surf the internet stop any data connection
- As long as you do not use GPS and/or location services, close them.

3. Prefer Wi-Fi rather than GPRS
It may be weird that the GPRS consumes more power when compared to Wi-Fi. For example, Wi-Fi consumes 5% charge; the GPRS connection consumes 15% charge. This may not be seen while viewing websites but in case of watching a video in YouTube or making a call in a VoIP service, it drains the battery at a rapid rate. So it’s better to use Wi-Fi to watch videos or making calls.
.- Wi-Fi network consumes less than 3G connection, it is recommended to use Wi-Fi

4. Avoid Live Wallpaper
The live wallpaper drains the battery to a considerable rate. So it’s better to use static wallpapers rather than the live wallpaper.Also use images which contain black color because the LED screens use less power to display black than displaying white. Doing this helps to increase the battery life up to 10%.
-Use a dark background, save battery. Light backgrounds need more battery.

5.Disable Data traffic
Many applications use data traffic in the background letting this phone to sleep. Some of the apps which use the background data traffic are GMail, Whatsapp, Facebook, Viber, Twitter, LinkedIn, Google Play, etc. These apps checks for the updates and for incoming messages all time. So it’s better to disable the background data traffic.
- Network 2G network consumes less than , it is recommended to use 2G connection
- If you do not surf the internet stop any data connection.

6. Disable Auto-Sync
This option comes under the background data traffic. This feature checks for the mail all the time. Which means you will be able to get the mail in your handset as soon as the mail arrives. But this service uses a considerable amount of battery
- Upload and sync only on Wi-Fi. Or stop sync on all accounts.

7.Do not use more widgets
- The more the widgets, more the RAM, more the battery will be drained.
- Dump the widgets

8.Disable Adobe Flash
Adobe Flash enables to watch videos in websites but it drains the battery a lot. The main reason why adobe discontinued its service from android 4.1 is this battery problem.

9.Turn OFF vibrations
The smartphones makes use of some energy to make a vibration, but when “Vibration on Key press” is enabled, while typing a word the phone produces more number of vibrations. It consumes more battery. So it’s better to disable this feature in the keyboard settings.
- Vibration consume energy. A low intensity vibration or even disable as reduce battery consumption.
- Disable Haptic feedback.

10. Power saving mode
If you use your device constantly throughout the day, you may want to consider using your device’s power saving mode. In fact, many of the tips suggested in this post are implemented in most devices’ power saving mode. For instance, power saving mode usually limits CPU use, reduces screen brightness, deactivates haptic feedback, disables data network when the screen is asleep, and lowers the brightness level of the browser’s background color.

The generally recommended advice is to disable power saving mode when you intend to use your phone’s smartphone features; otherwise, turning power saving off can help you stretch your battery life further. So, for instance, you might want to disable power saving mode if you plan to play games on your phone, or else you could experience lag or jitter.

11. Do not try to overcharge
Normally the smartphone charges up in 1-2 hours. But if you charge it throughout the day, it lowers the life-time of the battery. Check the condition of the battery often to have a good battery life.

12.Reduce screen timeout 
- Screen timeout should be as low as when not using this device to enter sleep mode. (15s)
- Sensitive buttons should be as little heated. (1,5s)

13. Uninstall unnecessary apps
You can never be too sure what's running itself in the background, what with all the multi-tasking, self-uploading, auto-replicating features in today's modern Android apps, so at least minimise the chances of something randomly hoovering up all your battery by constantly trying to connect to some non-existent server, by deleting any unused or old apps. Some apps are resource-intensive — either by nature (as in the case of games) or by developer incompetence or negligence (as in the case of poorly written apps).

14.Never leave applications open 
- Never leave applications open in the background for long time. Set the limit to 1 or 2

15.To root or not
Rooting may have drawbacks but the benefits far outweigh them. One attractive advantage of rooting is that of possibly improving your device’s battery life.

16. Debloating
Rooting itself won’t lengthen your battery life. Rooting merely opens the gates to your device’s restricted partitions and directories. With such restriction gone, you can remove useless apps (e.g., bloatware from carriers or OEMs), especially those that run as background services, wasting away precious battery power.

17.CPU underclocking
With root access on your device, you can also install apps that can improve your system’s performance. A CPU controller app, for instance. Three names instantly spring to mind: SetCPU for Root Users, No-frills CPU Control, and CPU Tuner.

Apps like these essentially allow you to tweak the CPU settings on your device. You can set the CPU frequency to stay at the lowest (and, as a result, use up the least power but sacrifice device performance) or to stretch the CPU to its maximum limits (resulting in better and faster performance, but at the price of heat, quick battery drain, and potential system instability).

Be careful when using such apps. There are risks involved; for example, your device could behave erratically when its CPU clock is set higher than usual.

18. Custom kernels and ROMS
As we have an unlocked bootloader and custom recovery in the process of rooting. Many custom kernels and custom ROMs. Feel free to look around XDA for guides on how to flash custom kernels or custom ROMs to your particular device.

Battery life is one of the biggest issues in the Samsung Galaxy S GT-i9070 Advance. Take your SIM card out, turn off Wi-Fi and never touch it and it'll sit there happily, lasting for a whole week on one charge. But try to use it for anything "smart" and, well, that's where the problems start.

...and keep it cool
Batteries work best in cooler temperatures, with prolonged warm periods gradually lowering their efficiency over time. Putting your phone in a looser pocket might help, or perhaps just gently fanning it while it charges. That might not be the best use of your working day, but at least you'll still be able to get on Twitter on the train home.

Updated :[Use following to get rid of battery issues]

1) Don't use any Memory cleaning apps/Task Killers or battery saving apps.
2) Go to Settings -> Location Services -> Uncheck All (Specially Permission to Google to collect data)
3) Facebook Synch settings to Never (Go Manually and check)

Bingo You are All set !!! Enjoy your Extended Battery Life
