Help Is this normal battery life?

Last night my brothers Xperia S was charger to 100%, however today he found overnight it had dropped to 46%! Which seems crazy to me, I have a Samsung Galaxy S2 and it only uses around 4% overnight.

I took a screenshot of the battery usage:

The only widgets he has is the pre-installed weather app and the stock music player. He had a McAfee anti-virus which I removed to see if that makes a difference. His settings are also battery conscious, e.g low screen brightness, wi-fi only turns on when screen does, NFC disabled, data disabled, syncs are disabled, etc.
 
I don't understand the Display being at 55% when on standby.
It could be a really badly programmed application keeping the phone awake (wake lock)
It's happened to me before on my Desire.

I used to use an app called Spare Parts, under the wake lock drop down menu.
Though I'm not 100% sure if it's usable on Gingerbread.


Here is mine.

Hmmm I dont know, im sure he doesnt have many apps running, ive downloaded a task manager for him and everything looked ok to me. Will have to double check.
 
Looked at Spare Parts for you, the Partial Wake Usage doesn't work.
Really does sound like a bad application to me.

I use "GO POWER WIDGET" to determine the battery usage, remaining battery percentage and number of hours remaining! its a very useful APP!!
when my Xperia S had firmware version 6.0.A.3.62: 100% charge = 18.44 hours of endurance(Maximum-when Screen Brightness is least, all external connections disabled)
After i updated to firmware version 6.0.A.3.73: 100% charge = 76.56 hours of endurance(Same conditions as tested with 6.0.A.3.62)

You can update to the latest firmware and get the maximum out of ur Xperia S battery..... :)

Ive updated it to 6.0.A.3.75 and it doesnt seem to have helped, in fact he claims last night his battery was on 40%, this morning it was dead! I installed an antivirus but it found no viruses, so I dont know whats going on.
 
I know it does not help you but this should give you an idea of what the phone should be doing............
Phone was unplugged at 8.30pm for me to do a night shift, I listen to music all night and when I got home at 6am I set it to wake me at 12.30pm as you see its still got 49% of bat left after some 16 hours so your bro is or as done something wrong.
1 bad app can do what your experiencing I have 250+apps on mine so most are ok:)

Good luck with sorting it out, Like Tyseth said if all else fails do a factory reset.

Have a look at the running apps and see if the power saver app is trying to restart itself, this app has been stuffed from the start, if it is then it will keep your phone awake and drain the battery.

If your running gingerbread firmware just uninstall the app, if your running ics then all you can do is force close it every time you restart your phone unless your rooted then use titanium backup to uninstall or freeze it ;)

Did you know that the display is the most power hungry and that the 63% doesn't mean it's using 63% of the battery, if you add all the percentages up, they equal 100%
 
i have with my xperia s straight after update to ICS slow menu and battery problem, also i use at that moment antivirus DR.web, and RAM BOOSTER PRO (task killer) , battery i have recharge couple time a day....
after I reinstall ICS problem gone, now i charge phone one time in 24h, phone quick like never :) but i not use any more antivirus and task killer, i think may task killer kill some programs to needed for normal phone work ?! :)

can u please tell me how to reduce the display in order to save the power?

what I did was: i changed the wallpaper from live picture to normal picture, reduce the brightness of the screen, turn off bluetooth, gps, kill app process that I dont use. I use wifi so I leave it on. what more can I do?
 
Don't use an app killer, without trying to have a massive wall of text I'll try explain it.

When you close an app normally, it doesn't close it, it keeps it frozen in a way, possibly in ram, so if you open it again and it's in ram it opens much quicker.

Closing the app with a app killer forces the phone to boot the app again from scratch using more cpu which in turn, uses more battery.

About the rest of it, you should be fine.
 
Thank you for your advice :)
So what should I do to close an app properly without an app killer?
Should I go like Setting>Apps>click Running then close the app from there?
I got the information that new batteries tend to need some time before reaching top performance, is that true?
 
Nothing, just press the home button.

As I said before about how an app works, if ram starts to get below a certain threshold it will kill the app that hasn't been used the longest.

Hope that helps a bit more
 
thanks so much :)
btw, it just a question to ask for a person who has experience in using this phone, how should I charge it to make the battery life become longer (or better?)?
