Reduce Android Jelly Bean battery drain

After updating to 4.1, battery life of my Galaxy Nexus is very short ( about 10 hours without heavy use ).

Unfortunately i found that Google Now is the evil ... Disabling it boosted battery's life up of about 50%

Why? Most is for geo services used for position history.

Another battery killer is google plus sync.

Try turning both off, and see the difference :)

To stop Google Now:
Click Google search bar (or enter Google Now service), click on the right bottom button -> settings
Click Google now and toggle to off. Turn off localization service too.

To stop G+ sync:
Go to the phone settings and scroll down to the account section, then press on G+ and disable sync.

BUG: Turning off Google Now fails when you don't have internet access. More than just annoying when you power is out for 90+ hours due to #Sandy.

Even following these directions Google Maps is still sucking power. After 1.5 hours on battery, Maps has used 11% and has keep the phone awake for 6 minutes.

Ok, I think I found it. It's Gogle Location Service that is using up lots of power, which shows up as Googe Maps in application power usage.

The instructions above should include the step of disabling google location services:
- Go to settings, Scroll down to the "Personal' Section and select "Location Services". On the location services menu, disable "Google Location Services'

Now my phone has lasted for 25 hours only using 30% battery.

This may sound weird but I disabled Google Now and now when I use the Google search and say "weather" it gives me the weather but in Celsius instead of Fahrenheit, before I enabled Google Now the weather default measurement was Fahrenheit. I know I can just tap the measurements but when Google's "Voice Assistant" tells me the temp it only does it in Celsius. I see where to change the setting in Google now, but if Google now is disabled, I don't see anywhere for changing the units of measure no little info icon on the weather card.

Hey. Hi Author. I just want to ask are you sure that is the reason? I will disable them too if you are sure. Thank you. Keep up your great work.

Google Now uses all our; GPS, Data conn, Map, Media Server, Sync,.. which consumes 'average' (more than LOW) power when taken separately. So imagine all of them used together! Plus processor activity and display will definitely Suck Up the battery! And since Google Now constantly monitors your behavior, the phone hardly goes even to the deep sleep mode. Overnight 5Hrs ""without even touching"" my G-Note phone, still had lost 20% battery in the morning.
But after disabling the Google Now, couple of texts, Flipboard, and average use, still lost only 10% battery for 2Hrs!!! Im still monitoring my phone, but seems that Google Now is the culprit.

Additionally I switch off the GPS unless using Maps, Data stays on except night, Sync is disabled for all except GMail, separately. I hardly use WiFi.

Hi @shivanadvp , sorry for the late reply.
Btw I'm pretty sure this is the reason: google now strongly uses geolocalization for all of its work and so GPS and wifi localization. Both uses lots of battery, that why Google Now is a battery drainer :)
