Best solution for Battery saving on Android.

Tip for longer battery backup on Android:

First thing first avoid using Gmail app for android to sync email instead choose to use stock 'Email' app and you can set a schedule of 15min from the settings of email app . It's same like we use in an iPhone like we choose fetch option instead of push option.

1. Gmail app in android is like we choose push service in iPhone ios, which is always connected with internet to see a new mail and will notify you immediately when a new mail will arrive.

2. But the app named 'Email' in android and setting schedule of 15min is like fetch service of iphone ios.

It really made a difference at least for me because i was an iPhone user and remember when we choose push in iPhone then its backup was really worst instead when we choose fetch then the backup was of almost 3 to 4 days for me, it was iPhone 4 and because we all knows they are producing same phone since 2010 with little changes i decided to switch to android and i tested huge phones but like i posted below, when i tried note 2 , i bought it in no time.

The only issue I had with it was the battery which was lasting just within 24 to 35 hours, but after using Email app instead of Gmail app its battery lasting in 60+ hours.

There are other way also for power saving on android powered devices

3. Disable your internet connectivity:

you might have seen that there are many applications that connect to Internet to update or to process some data. So it is necessary to keep a check on the internet usage, because these usage highly affect your smartphones battery backup.

One thing you can do to stop using packet data ie; Internet services. is to install some app viz; juice defender or to do it manually from the settings, you can simply do it by changing the APN of your service provider.

To do this manually go to Settings > Wireless Controls > Mobile Networks > Access Point Names. From here you will get list of services that you use to connect to your Internet, simply select the service click edit and change the name of the apn.

How it works is that incorrect apn name will not provide you access to internet and thus avoiding your applications to drain your battery.

4. Airplane mode:

Most of the people switch off their mobiles during the night time to save the battery or turn it to silent mode, but the sad part of it is that it doesn't save your battery it hardly provides 5-10% backup. Instead you can go for Airplane mode. This mode lets you keep your smartphone on but not using any network services as i said above the network services drain you battery than any other use on your smartphone.

You can do it by long pressing call/button and from there you can select the airplane mode

5. Other tips:

Always Turn OFF your Bluetooth,WiFi or any other services and task when not in use.Also try keeping your Display Brightness low.
