This is my Xperia S.

12h since last charge.

Almost 5h screen time.

Still 35% of juice left.

3 min less than 3 hrs.. My display brightness is just 15%.. Yet it looks so good.. :) I <3 my SXS..
[Sony Xperia S, Acro S, Ion] yw2012:
May I ask what ROM and kernel are you using? Many of us here average 3 hr screen time at best with everything stock.
[Sony Xperia S, Acro S, Ion] DrKrFfXx:
I don't really remember what kernel I'm using, it's been a while since the last time I flashed my device. I think i settled on stock kernel and a rom called Du@l Core v9.

My battery life

I tweaked mine alittle ...
[Sony Xperia S, Acro S, Ion] true-blue:
I dont know why do you even need a "smarthphone". Buy smtng for 50$ and use it for a week without charging. This isn't a contest who has a longer battery life without using the phone actually.

All the best.

Look at my signature and make yourself the connection... ;). I'm using the S quite active on the go, just showed that the battery life is very good when you use your smartphone only when needed.
[Sony Xperia S, Acro S, Ion] true-blue:
I just saw on your profile that you also have n7 im on S only, and so must go to profile to see signature. :D . Must agree, that S has quite nice baterry life, one day with 3-4 hours screen, (3g on). 2 days with less surfing.

Battery life improves with time, esp after removing junk apps.

But the display really suck everything out of the "non replaceable" battery.

battery behavior should be better :/ at least with gps usage, 1 hour of gps navigation drains around 40% of my battery

My battery last around 16-18 hours with high usage..

It's enough for me, almost everywhere i am ( work , home ) i can connect my xperia to the power.

High graphics games Drains battery faster with overheating

Whenever I play "Shark Evolution" or "Jetpack joyride" in my SXS it gets too much heated. It gets upto like 43 degree celcius :eek: if I play for like 30-40 minutes. Also my battery gets drained almost 15%-20% in this time :( .

I just wanted to know that is this normak for SXS?? I have everything stock with kernel updated to .55 firmware and 4.0.4 ICS.

thanks

[Sony Xperia S, Acro S, Ion] Felimenta97:
It's normal...

My battery life a few days ago:

Enought for my day. The time you see WiFi is on is when I get home from school...
[Sony Xperia S, Acro S, Ion] inyourfacedunk:
I still don't understand how people think battery life of less than 24 hours is normal.

I got my Xperia S a year ago. I was getting up to 4 days of life (not even fully discharged) with light usage. 3 days with moderate usage and at least 2 full days with heavy usage (not including games). One of the weirder fixes was to leave wifi turned on, but that only helps so much and in reality is a silly "fix". Turning something off should use LESS battery, not more.

There was an update some time ago that ended up with my battery now dying in less than a day with little usage. 70% charge at night and wake up to a dead phone.

The phone never hits deep sleep and something they updated keeps waking the phone. That's why on everyone's screenshots you see so much activity on awake, even though the screen is off most of the time.

This is very frustrating.
[Sony Xperia S, Acro S, Ion] Dr Goodvibes:
It is just a matter of configuration and usage that dictates the battery usage.

I haven't really worried about optimizing my XPERIA LT26i with JB 4.1.2 arriving any week now, so my phone is just stock with rooted kernel and a few SetCPU profiles.

I get a good day plus out of my battery, with the odd call, lots of web browsing/RSS reading, email and the odd SMS/MMS .

One should see good flat-line plateaus when the phone is not being used, otherwise you're just wasting your battery. :)

I've not had any problems with getting the XPERIA LT26i into 'deep sleep'. This is mostly the first target in getting good battery life.

The following pic does not match the above battery history as I've charged the phone since then.

Currently running on 6.1.A.2.55
[Sony Xperia S, Acro S, Ion] inyourfacedunk:
It seems to have decent deep sleep stats, however as you can see on the usage stats, it is awake almost the entire time. Even when the screen is off for extended periods. This is what never used to happen before the updates and is what I believe is causing the battery drain.

I am just hoping that JB fixes this and that it comes out very soon.
[Sony Xperia S, Acro S, Ion] PLovrin:
I tried FullHD video with 100% brightness connected to speakers max volume and it managed 3hours of playback.
[Sony Xperia S, Acro S, Ion] Dr Goodvibes:
True. Hurry JB, hurry, hurry.....

The top 'wakee-wakee' I noted on my XPERIA LT26i running 4.0.4 was email(~133) followed by Google Services(90).

If I look at the time held awake the top is Android System at approx 3hrs, then System(*wakelock*) followed by email.

I have push mail and imap with idle refreshes and etc so I'm sure I could refine email a bit, but if you look at Google Services or Android System processes, there is not so much you can do to limit those processes. (HDMI control service, time daemon, surfaceflinger, and etc, etc,...

If I look at my XPERIA X10i with 1800mAh battery, the history indicates the system is NOT being woken as much. And Email is the same profile on both devices as well as all the same Google Play applications.
[Sony Xperia S, Acro S, Ion] skycamefalling:
These permanent "awake"-phases are the same for me and it is very frustrating because nothing can be done against it. Even in Flightmode without any connection, no Facebook and no other apps working in background the phone always wakes up from deep sleep.

I really don't know which System process or included and not deinstallable bloatware is the cause for this but it keeps sucking the battery even when the phone is not in use.

For comparison:

My Sony Acro S needs 2-3% battery per hour when I leave it on the table without any background updates.

My Nokia Lumia 920 needs 0.5% battery per hour with weather, Email and Comic-Updates.

This is not acceptable. I love my Acro S but the awake-issue is better be fixed in the JellyBean update otherwise I will switch completely to WP.
[Sony Xperia S, Acro S, Ion] tOrNadO™:
After using Qualcomm's official battery saving app "Battery Guru", my battery backup has definitely improved.. Differences i have experienced are

1. Wakelocks have reduced. I don't lose more than 5% overnight(previously used to lose around 10-15%).

2. Also i have my Wifi ON at the time i am home.. Considering it, i can browse for another half hour extra than before.

3. Able to play games too for more time now.

I have posted the SS.. Wifi was on for around 7hrs 15min, made 3 calls, listened to music for an hour, played 3 games(NFS MW, Subway Surf & Airport City) for around 1.5 hrs max, around half hr of chatting through whatsapp..

For few who are wonderin wt settings i may be using,

Display brightness 25%, the above app i mentioned, using Stock kernel itself(bootloader locked) and XZXperience2 ROM.. Also unchecked Bravia Engine 2 OFF... Hope this helps for guys who are experiencing battery drain. The app is in themes and apps section.. Enjoy.. :)
[Sony Xperia S, Acro S, Ion] vkeza057:
The real issue

You can see my battery stats attached. Slim Bean, normal usage, MX Player for half an hour, some calls, little browsing... not much. Wifi and data were on only while browsing. The Auto-sync was off. The cpu was at 1026 MHz all the time except while playing videos when it was set to 432 MHz. Wheatley governor. The brightness was at 20-40% at first, but later I raised it to 50% because it appears to have little effect. Also, the phone was on Airplane mode from midnight to 7:30 and set to 192 Mhz! It lost 10% during that time (while it was in deep sleep).

I get similar times with Auto-sync on and cpu at stock or even OCed to 1.7

Another thing:

I've used Galaxy S before... it too had major issues with battery life... no more than a day of normal use with 10-20% overnight drain. After some time, the battery reached its full potential and the devs made incredible progress with kernels and roms which increased my battery life to 3+ days of light/normal use. I was used to loosing 1% over night. Then came Xperia S... :)

Now to the point...

Xperia S battery is adequate, it will drain more if you use it more as it is with any other smartphone. The real issue (in my opinion) is the 10+ percent overnight/idle drain. The screen is off, CPU is at min freq, Airplane mode... I've even used Deep Sleep Battery Saver a few times (not now)... the same. I can't turn it off completely because it wakes me up in the morning. :)

There is something in this Android/Qualcomm combo that just doesn't work.

All things considered, I'm removing all of the battery and cpu saving/monitoring apps, restoring stock cpu freq, setting display brightness to 50% and re-enabling the Auto-sync. I'll use/enjoy this device the way it's meant to be used and charge it every night.

It is obvious that until they fix the drain you will not get 2 days of normal/fun/pleasant/acceptable usage out of Xperia S battery.

P.S. Someone should make a guide/FAQ for people having short battery life due to inexperience. I remember the times when I used to enable every single feature on my first smart phone and wondered: what the hell is wrong with my battery. :)

P.P.S. The fact that my stats show that sometimes my phone was not awake even while the screen was on is funny.
[Sony Xperia S, Acro S, Ion] dds111:
I tried all different roms and none of them stand more than one day. Maybe day and a half but then i must allways have my charger with me so i charge it every night.

[Sony Xperia S, Acro S, Ion] birnee:
as for normal use(wifi on most off the time, few texts some calls) the phone hold 1,5 to 2 days tops. on weekends when I play with it I have to recharge ever 6-12 hours^^. days of immortal 7days-on-battery nokias are long over :]
[Sony Xperia S, Acro S, Ion] vkeza057:
Here are the screenshots of my battery usage with no saving tweaks, no airplane mode, full sync, full freq and the same normal usage (Just so happens I used the same apps for about the same time). The difference in battery life is about 5 hours which makes no difference to me.

Finally, I flashed the last official stock GB rom (ftf) and the battery life is great. Waiting for official JB...
[Sony Xperia S, Acro S, Ion] Odeira.Oloap:
I'd be lucky to get more than 8 hours.

And for some reason, my phone doesn't "sleep," (wakelock thing).

What was your screen on time? Looks pretty good. You have to accept that XS is capable of 4-5h screen on time. Pretty normal with most phones.

No matter what I tried I always got 4h. Oh, and difference between 25% and 50% is minimal in terms of battery life. I did some tests and it's really really minimal. I posted results somewhere in this thread.

[Sony Xperia S, Acro S, Ion] tradingtoms:
My advice for you would be to turn off auto-brightness. In the 1st weeks after i got my Xperia S i realized that exactly that setting likes to drain my battery a lot. Basically everything screen related drains the battery. And an application that let's you automate when GPS,Wi-Fi, sync etc. turns on/off can be the best helper for battery to last longer that 24 hours.

Here are my stats - barely used my phone today, but still it was used. Every night for atleast an hour the screen is on (e-books, playing simple games and surfing the web), once a day i try to sync everything and every hour i sync the weather app + 2 hours of music listening while working out. Brightness during day - 80%, during night <20%.

*before connecting it to charger battery was at 40%. with mobile network always on battery would be at 25-30% level.

I have already deleted com.sonyerricsson.android.wakeup from titanium backup. Is that the same one or it has nothing to do with fast dormancy apk?

Meanwhile I checked system/app folder, there is an app named fast dormancy-in call.apk. Is that the same one.?? Safe to remove.?

Sent from Sony Xperia™ S using XDA app.
[Sony Xperia S, Acro S, Ion] conalt:
I think the in call version may be needed. In my system apps folder below the in call apk there was one called fast dormancy wakeup, which I think is the one he is referring too.

From my personal observations freezing com.sonyerricsson.android.wakeup with titanium backup has not deceased the number of wake locks on my device, but I do feel like it has somewhat reduced the battery that is being drained during them.

Kernel?
[Sony Xperia S, Acro S, Ion] PLovrin:
This is really good for me:

I noticed that for most of the time HDMI or tv.out was awaking my phone so I blocked it. And I also blocked com.sonyericson.android.wakeup, everything facebook related and some other stuff.

This was before:
[Sony Xperia S, Acro S, Ion] conalt:
Things do seem to get a bit lost in a thread of this size.

So recently there have been two things that have helped to prevent a lot of those random wake locks.

The 1st thing that has been mentioned many times was freezing or removing the com.sonyericson.android.Wakeup apk from the system apps folder.

The second one was the fast-dormancy-wakeup.Apk also in the system apps folder. You can just rename the apk extension or move it onto the sd card, and reboot the phone.

On my phone at least, removing this fast dormancy apk really has made a big difference reducing battery drain when the screen is off.

Screen on time for this image was 1h 48min.
[Sony Xperia S, Acro S, Ion] tradingtoms:
Wow, considering how much the screen is on and wifi is used, those are some great performances. Maybe someone should sticky this information about these wakeup calls so new users know how to extend their battery life. :cowboy:

[Sony Xperia S, Acro S, Ion] skycamefalling:
No, this is not good. You hardly used the phone and still the battery is down after only 2 days.

With low usage, the Nokia Lumia 920 lasts 4 days for me while my Acro S is done after 1.5days with the same usage.

There is obviously something wrong with the Sony-phones. First I thought this issue might be solved with the coming Jelly Bean update but I've experienced the same battery drain on the Xperia Z with Jelly Bean. It's clearly a issue that only Sony has, since the HTC One and the Galaxy Nexus do much better.
[Sony Xperia S, Acro S, Ion] glenkocco:
well with medium usage (which is my normal usage of the phone) i get a day and a half of battery life.. ok, it's not much, but now all smarphones have an average 1 day of battery life.. some more, some less.. but the average battery life it's 1 day.. with stock rom it was impossible for me to get to 2 days even if the phone was off XD so i'm happy with these results after flashing cm10

4 hours of screen on time from 100 to 0. Watching videos from 4 to 5h. Regular day wifi 3g on gmail sync, lets say around 16h with 2 to 3h screen on time.

I am now on 15h30m since unplugged with 2h30m screen on time and 34% left. Was watching some videos, browsing, xda, gmail, google+ and some other stuff.

If you use phone with small usage lets say around 1h screen on time it should hold 2 days of usage.

And one advice if you buy: dont put brightness to less than 30% because in terms of battery usage there is no difference between 50% brightness and 15%.

This is all from my experience and tests.
