Best battery life

[searayman]

Whats a good way to keep my battery in check? I am using a EOS rom with franco kernal. Anything I can do to sqeeze some more battery life?

If possible, turn off blue tooth and location services.
Keep the apps simple and clean. Live wallpapers look great but take battery away
Franco kernel, I'm no expert, but what I've tried from reading is:
- use the lazy gov setting. 1200 frequency is stock, experiment with lower frequencies
- play with the power mode settings
- use thd 384 ghz nightly download, As the other rom overclocks your gpu

Another thing you can do is to download something like Juice Defender. It gives you the ability to turn everything off for predetermined intervals. I noticed dramatic battery life increases.

I found a huge difference when I turned off the NFC ... Don't really have a use for it most of the time, so I decided to turn it on when I need it.

You really need to monitor your own battery use to determine what (if anything) can be changed to improve it. Use an app like Better Battery Stats to do this. It provides a lot more information that the standard battery stats in the Android OS.

However, as a general rule these things will effect your battery life.
1) Screen use - this is the biggest user of the battery. With such a large screen, you know it is going to suck power. So use your screen as little as possible. Use short time out settings, turn down the brightness as low as possible given your environment and use autobrightness as little as possible. There are times when you are in situations where the lighting changes drastically where autobrightness is nice, but it uses more battery power to constantly monitor brightness levels when the screen is on. So turn it off whenever possible.

2) Signal strength - another huge factor in determining how your battery life will fare. A mediocre or poor signal will use more battery than a strong signal. There generally isn't a whole lot you can do about this, but it also explains why battery performance is so different between users.

3) Radios - using 4g and even 3g take power. Obviously running a totally separate LTE radio is going to use more power than just the CDMA radio. So turn off 4G as much as possible. You really don't need it for general use and it is easy to turn on if you are going to be surfing the internet a lot or downloading large files. However, even using the 3G data connection uses more power than just wi-fi alone. So use a program like Y5 or Juice Defender to turn off the wi-fi radio when you are not near a normally used access point, but use wi-fi as much as possible. When you connect to a wi-fi network, the phone automatically turns off the 3G and 4G connections which really saves power. The NFC radio is another thing to consider. If you don't use it, then turn it off to potentially save power. In earlier versions of Android, GPS seemed to use power even when an app didn't call for it. However in ICS and certainly JB, the GPS radio does not seem to use power unless an app calls for it. So I leave my GPS on all the time and I haven't seen a battery drain from it. But again, if you don't use it, then feel free to turn it off.

4) Notifications - programs like your email and especially social media apps like Facebook, Twitter, and Google+ can really run down your battery if they are constantly checking for notifications. Personally I would suggest removing all of these social apps and simply using the mobile browser to look at these sites, but I realize some people have to be so connected that they won't be able to do this. Just be aware that you are going to use a lot more battery life with these apps. (Actually not only does the apps themselves suck a lot of power, we are all so trained to check our phones everytime we hear the notification chime that we also use a lot more screen time too). If you have to use these apps, make sure you turn them to not constantly check for notifications, but set a specific time schedule and try to go as long as possible between checks. Using a program like Better Battery Stats can really open your eyes as far as how much these programs use your phone's resources.

5) Apps - besides the social media apps, you may find other apps that are large resource hogs. Many times it is due to a bug or an error, so check with the app's developers. But if you find an app that is using a lot of your phone's resources, consider removing it completely. Odds are there are some alternatives available to you that may not use as many resources/power.

6) Kernels - part of the low lever OS code. If you root and unlock your phone, you can substitute the stock kernel for one that a developer has written. Kernels can play a large factor in overall battery performance. Luckily there are some good ones out there. You want one that has the right mix of speed and quickness and battery life for your usage. Personally I use Leankernel and love it, but others swear by Franco's kernel or others. Be willing to try some out, but make sure you run each kernel for several days or a week or more before you change to another kernel. You cannot change kernels everyday and expect to get an accurate picture of how well each one works. There are too many other variables that can occur in every given day that you need to give it a few days of use before making a judgement call.


So that is a quick 10,000 ft overview of battery performance according to me. I hope it helps.
