Battery - the usage and standby always the same

I have an iphone 4 running 4.1. suddenly since last week the usage and standby time is always the same.

I run my charge down completely until it turns off, then I leave it charged past 100%, but when i start using it they are both the same.

iOS 4

Hi guys !
Listen, I "might" have found one issue. It appears every one have the same problem but each time due to a different app or something.
Anyways, yesterday was an update to "Download meter", an app I use, and this update included something called "precise tracking". What this does is it runs constantly in the background. I had my usage and standby time equal since that update.
I turned it off and am now charging my iphone back up (hard reset made me lose the usage and standby time).

I let you know if this is the source to my own issue.
Anyways, this would prove that some apps still drain much power while backgrounded : i went from 27% to 18% in just an hour and a half of iphone in sleep mode !

I know this can't be the issue to all of your problems since i realised mine this morning.
Good luck !

Alex.

I too now encounter this same problem. Except I'm on a iPhone 3G with iPhone OS 3.1.3 (no multitasking). My usage and standby are always the same and the battery drains like crazy.


White Shadow, this precise tracking feature that you mentioned, is this the feature of an app or is it part of iPhone 3GS or iPhone 4?

1st. Turn off WiFi.
2nd. Turn on everything on cellular data (3G, Cellular Data, Data Roaming)
3rd. Wait until iPhone gets 3G signal, after it wait ~5mins
4th. Turn off 3G (DO NOT connect to any Wi-Fi networks before this is done), DO NOT turn off cellular data and data roaming.
5th. Turn on Wi-Fi. Connect to home Wi-Fi if available.
(please don't blame me if this does not work..(it does for me). I get this info from another people...)

This is the final solution for me! It works 100%


Thanks a lot!

Hey guys, I was having this exact same problem with the usage and stadby times being exactly the same. Was able to find out that leaving pages open in safari was the cause of my problem. If you close all the pages before going back to the home screen it might fix the problem for you. Also found out in my research that you can close apps by double tapping the home button to pull up the multi-task bar and then holding one of the apps for a few seconds (like deleting one from the home screen) and then tapping the minus buttons on the apps to close them.


Hope this helps and best of luck to all of you who shared this problem.

Oddly, this sequence of events worked for me as well (at least for now). I was able to turn off celular data as well without the problem recurring. Before attempting this, I had done a hard reset and a network reset to no avail. It seems that this solution must work for rogue apps running in the background that search for your cellular data signal for some reason. Extremely frustrating, but thanks.


I should mention that I've had this problem before, and and hard reset and network reset did the trick, but as I said, it didn't work this time. Perhaps it was a different rogue app causing the problem that time? (I don't even have that many apps installed)
