I don't think setting the brightness to Auto is the best for saving battery. When in auto, the light sensor is turned on and some processing has to be done to define the brightness every time the screen is turned on. And that consumes energy.

I always keep mine at 50% and, when in very bright places, I go for 100% brightness.

Hi again, today i disabled my wifi and data manually whenever i wasn't using them and manually enabled it whenever i needed it. It worked a lot better and i left my house with 85% charge and i used my phone a little bit more than yesterday and it used up a little bit over 25%. I also played around with my juicedefender settings and hopefully it will work better. I will set my brightness to 50%. I'll post back in a few days. And is my battery working properly, because i honestly expected it to last a lot longer. Also thanks for the suggestions.

I really like 2x battery for controlling battery usage by data connections. There a light version as well. It basically turns off mobile data when the screen is off and turns it on when the screen is turned on. It can do the same for wifi as well. The light version will reconnect and sync everything every 15 minutes (or you can turn sync off). I paid for the full version and it allows you to change the sync time to longer increments. I use it mostly because I don't want to have to remember to toggle and where I work the 4G signal isn't so great.

I haven't downloaded any task killers, but when i'm done with my apps i go in to the settings and close them.

Have the same problem! Brightness is low, internet is off, when I don't need it, still the battery is weak!

Battery Full
You said you had a flip phone before and the battery lasted a week, is this your first smartphone?

Smartphones have a 24 hour battery life at best, This phone has an above average battery I have had 48 hrs out of it..

other things to get in mind is the ROM you are using, I see you are on stock Ice Cream Sandwich, ICS have a good battery life, I have tried Telstra Jellybean and it was not as good, I also get excellent battery life with epinter's CM10

I am very satisfied with the battery life! I also recommend x2 battery, which seems to prolong battery life with little to no impact on the usability of the phone (at most a potential short delay on emails when not on wifi). I generally use wifi whenever possible which use much less battery than the mobile modem. Also I have disabled a few stock apps that I don't use e.g. the non-gmail (stock) email app. The phone is not rooted and using stock o2 JB rom.

I think it is as well. I admit it may be a little "inflated" by using Wi-Fi mainly rather but impressive nevertheless. Wi-Fi or not I generally experience good battery life. I have the normal non-Maxx edition bought in Germany September last year.

Also have a look using Better Battery Stats app to see what your most battery hungry wakelocks are, especially Kernel wakelocks.

I had issue when I first got my razr as I was using it on a network that doesn't have Fast Dormancy yet the phone has fast dormancy enabled, so i had to freeze it and battery life improved a little.

But unfortunately fo me the main problem was where i live. I'm in a city, so it's not a lack of cell towers, but for some reason at home my battery usage is insane while connected to mobile data, 9%-11% an hour with no use compared to 2%-5% elsewhere around the city. (Am thinking it must be getting bounced from tower t tower trying to get a better H+ connection) As soon as I switch over to wi-fi tho (which I have set to always on,) my battery usage drops to about 0.8%-1.2% per hour in standby.
