How I get >40hrs of Battery Life Per Charge!

[nextmill]

I keep seeing threads about people having problems getting good battery life. I can get over 40 hours of battery life on a single charge. I've documented a few key steps below:

1) Make sure your email program and Word with Friends aren't set to check every 5 minutes. Yes Word with Friends checks their server EVERY 5 minutes, seriously do you need to know that your buddy just put a word on the game and you must update it right away? Disable that so you can check when you run Word with Friends. Same with your email program, don't have it check every 5 minutes, change the interval

2) Enable WIFI! Yes, enabling WIFI is your FRIEND. Why? Wifi uses less power than the 4G antenna. When your phone has WIFI connection, it doesn't connect with 4G, thus saving you battery life. At home or at work, connect to the WIFI instead.

3) Upgrade to v4.04 ICS. Yes it makes a huge difference. Get the Galaxy Nexus 5.1 toolkit, enable usb debugging, perform the adb backup to backup the whole phone (apps, settings, storage, everything). Unlock the bootloader, install the Clockwork, copy the 4.04 image zip down to the phone after its booted fresh, reboot to the recovery mode and start the upgrade. Once upgraded, login with your google id, enable usb debugging, run Galaxy Nexus toolkit and restore your backup, it will restore everything, all your apps, all your settings, all your little adjustments here and there.

Here is an image of 12 hours of use, I still have 75% battery life left.

Is there an option to change the frequency on the native Gmail app too? I couldn't find where to change that setting...

Thanks. I'm not the most technical with rooting and such so I wanted to wait for the official update to come out but man that 75% after 12 hours of use is pretty drool worthy

Do you have a screen on time for the day? Or even the 12 hours?

Exactly! I can get 40 hours easily on my phone on a weekend when its at home, on wifi, and im hardly on it. I need a screenshot of his screen on time too.

Correct me if I am incorrect... I was in belief that Gmail uses push notifications opposed to checking the server.

I have found that it on Screen On Time is the true test of battery life. If Didn't use my phone, didn't have twitter, facebook and google plus and touchdown not running, my phone can last me 2 days easily. So these numbers arent impressing me.

But regardless of how much time, the screen on time will reach 2hrs for me before it dies. Some people can get 4hrs, or more...thats the true measuring stick.

30m is about 1/4 of the 2hr mark which is should land you at around 75%

You hit the preverbal nail on the head. Usage varies from person to person, which is why some get seemingly horrible battery life and others get amazing battery life when comparing battery hours alone.

The current 4.0.4 release does not have an option to change the frequency of checking for new email.

My screen on time for the last 29m 37s was about 29m 30s

I would think wifi would suck more battery as opposed to save some because if its always on its constantly looking for networks to connect to no?

I think the intent is that you should use WiFi when you are at a stationary location (work, home, restaurant, etc.) that you know has the option. It would not be pinging constantly in that case.

Additionally, you can have the WiFi sleep when the screen is off, so that should save some juice, too.

Right on about the screen time. I have no problem getting 20-30 hours out of my phone with the extended battery unless I get a lot of calls, use Navigation of tether with it. I could see getting 40hrs without too much trouble.

But it should be noted that there have been issues with Adnroid OS using as much battery as the screen. This happened on my first unit and I couldn't stop until I flashed a fresh ROM on it. I had a few other bugs so I exchanged the unit. The second unit worked much better right out of the box.

I bring this up only to point out hat for some users, the battery issues are real and not just a matter of them using the phone more than they thought they did.
