I have been reading in many threads in the Xperia Sola/P/U sub forum that one should turn off auto rotation to save battery if that feature is not being used.
I used to do that. Until yesterday evening while playing Temple Run, when a doubt came to my mind.
Since auto rotation is turned off. But the guy in the TR2 picks up movement from tilting the phone also. Which means the gyroscope (on whatever device that is used to measure angular movements) must be running even after auto rotation is turned off..
So if gyroscope is still on, is there any actual battery saving?

By turing off auto rotation means
Screen will not rotate while in normal apps, gallery, brpwser etc
It doest mean it will completely turn ur senor off...
Games require gyroscope so it will run while playing

That will turn off sensor for screen rotation but not for games.
But if you arent playing game and you have autorot turned off you are saving battery
Ps sorry for my bad english

If Auto Rotation off disables sensors, how are games still able to sense movement.
If auto rotation off does not disable sensor, how is battery being saved?

Games are exceptions tell me rotation of ui is more frequent or playing of games use common sense and if you don't believe thn observe it

It does disable the sensor, but when you install some apps (games in paticular that use the gyroscope and stuff) they have the permission to turn it on, but outside of that app it will be off. Very simple actually

Turning off autorotate will not save your battery.
Also factor in the negligible savings from cpu not polling sensors, or processing animation for rotation.
It will NOT save your battery at all...

See my previous post. However small, a saving is a saving.

So i downloaded [email protected] battery monitor app. . Googles services had 406 wakelocks ... Is this normal??? My battery is crap on just 4g (even disabling mobile data on occasion). I get from 8am when i take the charger off till about 3pm. (maybe surf web for 10 mi.utes send a few texts, mostly the screen is off). See below... Is g services the culprit? I dont use gps either or anything for location
What app is that?
100% stock. 21 hours unplugged time and 5 hours 4 minutes screen on time. Just because they are "wakelocks" doesn't mean they are keeping your device awake. It means that they are able to. Only 35kb was sent and your device was only kept awake 69 times. That isn't much. I mean damn man, TOTAL awake time according to your screenshot is under 2 minutes lol. That isn't even denting your battery. The culprit is elsewhere.

whats the name of this app?
I have the same app. Android services is at top for me and it says its using the gyroscope and light? Motion settings are off and my on screen time is only at 1h30min. What's up with this because its killing my battery.

Light is referring to the sensor. The ambient light sensor. The gyroscope and such are used for location data and screen orientation. Screen orientation is seperate from motion controls, so check and see if it's still active.

Alright. So I turned off auto brightness and set if at medium. As for the gyroscope, screen rotation is locked and has been. Its clocked in at two hours now which is right on par with on screen time. Is this because i keep GPS on because i thought it was only used when needed. Also in the location settings under Gps there's another setting to use motion sensing indoors that will improve battery life should that be checked because i have that unchecked

Ugh now it won't let upload pics. Anyway i found the apps that use the sensor the most. Words with friends came out on top as well as the gallery. The gallery i understand because when you tilt your phone so does the UI but i don't use it for three hours. Also, since when does Wwf need the gyroscope ? I think I'm going to have to delete Wwf and see how that goes. What do you think about the gallery constantly using the sensor? Glitch?

I am using Ace of a year now. And I still cant understand that Samsung guys gave proximity sensor just to make screen go off when you are in a call. As proximity Sensor wont work for other uses (like snoozing alarm or silent an incoming call etc.)
Can those things work for my ace? is there any tweak or something that will make it work?
your help will be appreciated.. ty
its for diming screen
Sent from my GT-S5830 using xda premium
so it means we can never use the ace's sensor for other things..
oh yes
you can use it for a lot of things

So I guess there might be an app to snooze alarm and to silent an incoming call.. isn't it?

SURE it's an app called TASKER, in tasker you can do anything !!! the problem is you need to know how to use it.... but... search for a tut......mmm basicly the app is:
IF->ACTION
FOR EXAMPLE you can use the sensor for silent a call when you face down the phone (yes, like sense )
the limit is your imagination
I recently purchased this phone and I am moving from a Nexus S, which had auto brightness however I can't seem to find it in the options of the Xperia, I did remove a few apps when I got it so I just wondered if anyone could confirm if the phone has the feature or not?
Thanks
Yes it has, but you cant confiqure this by your self without root and some mods.

Thanks for the prompt reply, I'm going to hold off rooting until I get my unlock code from my network.
Its on by default.

I used "Quick Settings" to turn off auto brightness but it's good to know it can be turned off without installing anything

Just tested the auto brightness in bright sunlight. It is working fine. Put my hand over the sensor and the screen got darker. Removed it an the screen got brighter again.
The brightness changes are very slow though. It takes the phone a few seconds to adjust. Which actually is pretty nice since you don't get abrupt changes.

Correct, that's the design.
Anyone having the same problem?
If so, was the feature removed or readapted somewhere else?

Hey guys,
I have noticed that Xperia S doesn't have a light sensor. but in whitepaper they say it is.
i really like to enable auto brightness control but with this i am unable to do it.
The auto brightness is working fine and it's always on,there is no option to turn it off,you need a third-party app to turn it off.

If u want to enable auto brightness just set ur brightness to about 18 percent and reboot! Then u'll notice auto brightness works!
