Mine has been very similar. Currently 6 hours @ 71%. Much better than I remember it being a few days ago

 

Get rid of the battery indicator app. They drain your battery.

Not that hard to find it through the settings. Also, spare parts will show it to you.

 

Where does everyone see a percentage for battery remaining? All I know of is Settings>About Phone>status.

 

I use the widget BatteryLife, and it does not "drain" my battery. I've tested it, and it does not keep my phone awake, or make it run down any faster (at least not enough to notice). It shows the percentage of battery life remaining, and you can set different colors for it at certain percentages.

Or if you don't want to install an app, the same information can be found by dialing *#*#4636#*#* (4636 = INFO, easy to remember) and look at the Battery Level to see your actual percentage remaining.

 

I agree that it has imroved the battery. I was fully charged at 130pm yesterday and by 7am this morning I was at 60%. Definately a big improvement.

 

Spare Parts app. will show you the same info.

 

where is the link to manually update and how do I do it?
