Hey guys

I have got more power with the phone by simply underclocking the device and changing the voltage with the cpu core using an app called proton voltage and voltage control lite

I am getting alot more battery power with these apps running but you need your phone rooted to use

Also turn of your brighteness to alow setting and use juice defender to manage wifi

This works guys no probs just as good as an iphone 4s for the battery lasting now

So this is my update after a full days use, and I must say post .73, the battery life is amazing with my use :) I'm sitting in the 30's so I can easily last overnight and into the morning probably.

Most of the day with WiFi on, and a good bit of the day with Bluetooth and music streaming. Lots of texting and XDA browsing, and a few app installations :)

I also didnt have that wake process frozen.

Not bad at all, I am actually a little impressed now :)
[Sony Xperia S, Acro S, Ion] Bosszwo:
Hi

Official update forum holland? Or are your rooted?
[Sony Xperia S, Acro S, Ion] shmoejoe:
I'm rooted, I have no idea if the NL one is out yet.
[Sony Xperia S, Acro S, Ion] eddyedwards007:
LMAO :-D Quality mate, quality.
[Sony Xperia S, Acro S, Ion] wing_zero8556:
My battery life improved a little bit overnight.. dropped 5% in about 8hrs. But on my X10 cell standby would be the thing that showed most usage overnight but on Xperia S it is "android system" which is using most of my battery overnight! It says keep awake: 3hr 23min, is anyone elses like this as well?

edit: Installed betterbatterystats and it shows that alarm manager is keeping it awake and the intent is com.sonyericsson.android.wakeup as discussed earlier in the thread. I have frozen it in titanium and have also renamed the .apk in root manager but it is still running somehow
[Sony Xperia S, Acro S, Ion] :
I had this problem since last Saturday that I purchased the phone. Overnight, with NOTHING running and totally stock, no GPS, WIFI or 3G, I would lose 30-40% of my battery charge.

So last night, I upgraded to 0.73 using flashtool, and voila, only lost 2% in 9 hours. Two percent! Brilliant!

Again, I did nothing else (no battery recalibration, no rooting, no process freezing, NOTHING) but upgrade to 0.73. Problem solved.
[Sony Xperia S, Acro S, Ion] del1701:
Which. 73 did you use?
[Sony Xperia S, Acro S, Ion] Yakandu:
My battery life is good enough. Unless i start playing games of course xD

3 short calls 5 sms some web browsing and some Wifi downloading =50%battery/24h

Im calculating usages and 15min Display On (30% brightness) = 1h Music (Volume 50%) = 12h inactive.

WTF display? yes, i know its 720px display but... WTF?

Wakeup and unused apps frozen (timescape, office, music/video unlimited, stock Gallery, Browser, email, music/video sharing, google books/videos, etc)

PD: im on UK .67
[Sony Xperia S, Acro S, Ion] mateusz243:
My screen uses about 70-80% of the battery it's ridiculous :mad:

I set up the brightness on 50% and switched the bravia engine off and still drains loads of battery. Also it drains about 23% overnight with wifi/bluetooth/gps/data off. Can someone give few tips how to fix the battery problem? :)
[Sony Xperia S, Acro S, Ion] ssj_jaypee:
Are you using the latest update?

Also bravia engine does nothing unless you view pictures/movies.

Is your phone new? Give it 2-3 weeks for the battery to settle too.

Drain it completely, then charge fully. Do this process a few times.

I can get a full day of use now and my battery only drops 5% overnight.
[Sony Xperia S, Acro S, Ion] eddyedwards007:
Battery only becomes an issue if you're not able to charge it. People who mention" my battery drains x amount over night", do you not put it on charge while you're asleep?

I get at least a day ( while I'm awake) of use and that's all I need. If you're at home have it on charge while you use it.

I don't understand this obsession with trying to get your battery to last for days,if your in the middle of nowhere, fair enough but come on guys, seriously!

It would be nice to be able to have a battery that lasts days on a single charge,but unless you get a simple txt and call phone it ain't gonna happen.
[Sony Xperia S, Acro S, Ion] mateusz243:
No im not using the latest update and yes the phone is new I get it a week ago. I always drain the battery completely until the phone switches off by itself. I saw that other users have about 50% usage of screen i just checked and I got 79%:confused:. I shall wait few more weeks and see how it goes hope ICS update will help a lot :P
[Sony Xperia S, Acro S, Ion] intellix:
As I had promised earlier (in the ver73 firmware thread), here is my observation based on a moderate usage using the new firmware. The battery looks freaking awesome now. Its been more than 26hours now and I still have 50% juice remaining.

I have used my phone with WIFI switched on for more than 12 hours. Rest of the time I had 3G On. The Gmail,Facebook and Google contacts sync is turned on. The GPS is turned ON as well.

Screen brightness is set to 30% (which is more than enough for me, When I need more I just turn the backlight ON temporarily.). I didnot play games. However, I did some light internet surfing and had voice calls for around 40-45mins. I also sent a few sms.

The stats look freakingly awesome. The guys have certainly done a great job in ver 73. And with out feedback on what else needs to be improved, this can only get better when ICS comes in.

(Note: I am on Non Rooted Stock version of ver 73 with no customizations.)
[Sony Xperia S, Acro S, Ion] :
Non rooted, SG version.
[Sony Xperia S, Acro S, Ion] del1701:
Thanks, I might flash this tonight ;)
[Sony Xperia S, Acro S, Ion] del1701:
Just flashed .73 SG lets see how the battery goes
[Sony Xperia S, Acro S, Ion] wing_zero8556:
com.sonyericsson.android.wakeup is still running on my phone but its use has died down by quite a lot since I froze it etc. Battery is getting a bit better now.
[Sony Xperia S, Acro S, Ion] Malooga:
You lot can't be using your phones and must just becseeing how much juice you can get out of them, or the .73 firmware solves a major issue. Playing Shadowgun the other day my phone went from 65% to zero in an hour! While charging!

Taking the phone back today as i'm still within my 14 day cooling off period, i've also had problems with the screen locking up too, had to do a few resets with power+volume.
[Sony Xperia S, Acro S, Ion] Cholek3:
I have unlugged the phone on Friday, 1700. 15mins on Skype, few minutes of voice calls, about 10 text messages, Tapatalk checking messages every 15mins, email sync is on all the time, about 5 mins of Temple Run, 1,5 hour trip in a car. Half of that time I was on Wifi, the other half - 3G or H. I know it is a light use, but at the moment, it is 1 day, 16 hours, 22 minutes after unplugged, and battery shows 49%. Not bad. .73
[Sony Xperia S, Acro S, Ion] Efe64:
Im really sick of this.

My phone is just faulty.
[Sony Xperia S, Acro S, Ion] Cholek3:
I already got it for 3 weeks and everything seems to be fine with mine unit.
[Sony Xperia S, Acro S, Ion] pixy132:
The display is definitely the battery drainer. It's a gorgeous screen after all.

In fact try turn off the backlight and reduce screen brightness to below 50%.

IMO that level of brightness is enough for normal daylight use.

Also, use the Power Safer that comes with the phone, turn on the timed saver option and set it to turn everything off when you're asleep. I get only 3% drop overnight with that enabled.
[Sony Xperia S, Acro S, Ion] bustervic:
Running the .73 f/w there is a HUGE improvement. I run Juice Defender too, and before I was lucky to get 16-18 hrs with heavy use.

Now I am at 35-40% with the same use. I am going to test w/o Juice Defender as well to compare.
[Sony Xperia S, Acro S, Ion] doministry:
BTW is there .73 FW for Poland
[Sony Xperia S, Acro S, Ion] GarethNZ:
Probable Cause of poor Battery Life

I read it some where in this XDA forum that the cause was related to the phone constantly changing WCDMA to and from GSM.

(Mobile Network Settings > Network Mode -> "WCDMA prefered / GSM")

So I tried it out and you can see the difference.

Minimal usage both days (< 4 texts type thing)

screenshot_2012-03-31_0959.jpg is "WCDMA prefered / GSM"

screenshot_2012-04-01_1121.jpg is "WCDMA only" (I figured that is the bigger battery drainer of the two anyway)

--- Even though Juice plotter shows a blank spot in WCDMA only it was on and has the data.. it just didn't produce the image for that time period.

I've heard the the new .73 firmware has better battery life, so it must correctly implement the network swapping algorithm.

Perhaps OP could update his 1st post?
[Sony Xperia S, Acro S, Ion] NightSky256:
This is a .73 behavior during an entire weekend, starting saturday morning ending sunday night...

i've not had saving-battery trends, you can se wifi on for a long time, screen often on, i took some pictures, made some calls (about 1h) texts, internet, installed apps, used gps and google maps for about 20 minutes, and my girlfriend played "Move the box" for about 30 minutes while i was driving...

it's impressive !

The message is in italian but it's simple... 1g = 1d the rest is the same in english ;P
[Sony Xperia S, Acro S, Ion] somemadcaaant:
Yeah confirmed the .73 firmware is considerably better, i did a complete wipe to be sure... everything on, facebook, twitter, gtalk, trillian, bluetooth, gps, wireless, 3g, exchange some youtubing, a few calls, no charging over night and im still on 51% for 18 hrs at dinner time.

I still recommend disabling 3g during the day if not using, ive tested 3g off with previous firmware and the phone lasting for for near 2 days with avg usage, i suspect .73 this will last even longer now.

-smc
[Sony Xperia S, Acro S, Ion] hololodilolo:
The battery life is much much better with fw .73. :D
[Sony Xperia S, Acro S, Ion] Static-Noise:
Irish (and possibly UK) users:

I've been in contact with Sony Mobile for our territory and they'll be escalating the information and the need for an update to the mobile development manager.

Fingers crossed, I will get more information in the coming day or so.

[Sony Xperia S, Acro S, Ion] blacksheepvn:
Do nobody know??????? :(:(
[Sony Xperia S, Acro S, Ion] gm007:
It's the same,but don't use the phone while charging like playing games....
[Sony Xperia S, Acro S, Ion] Nimche:
Installed the .73 and after a few restarts during last few days I can say that battery lasts much longer than before. Moderate use of phone after 15 hours I am at 66%.

Pretty good.
[Sony Xperia S, Acro S, Ion] doministry:
What this question is about?

You can charge however you want, it doesn't matter
[Sony Xperia S, Acro S, Ion] sssache:
Yesterday morning i had this drain battery issue. In the evening had like 65% and in the morning just 12% with everything but the gsm turned off... so i started an ''investigation''. In the battery status i saw that google+ is taking a lot of juice even if i don't use this app. In the Account & sync settings the process called Sync Instant Upload was keep syncing all the time (already was uploaded 135 mb of i don't know what and i don't know where :) ). I found out that g+ and Sync Instant Upload are working togheter. So i open the Play Store (market) and search for g+ app and uninstalled from there, because directly from the smartphone is not possible. After g+ uninstall my Xperia S in standby with only gsm on is taking 0,2 juice per hour. Please remember that after uninstall g+ will stil remain on the smartphone but is not installed anymore.

In my case was g+, but if you have battery drain issue just take a look of what is using the battery so much. Be careful at the social app, usual they are responsabile for battery drain.
[Sony Xperia S, Acro S, Ion] 4lex96:
there are root for 0.73 build?if it isn't can i root the 0.67 build and then flash the 0.73 or i lost also the root?
[Sony Xperia S, Acro S, Ion] Rashkae:
There are entire threads about this in the DEVELOPMENT section. Please search, or at least LOOK, before you post!
[Sony Xperia S, Acro S, Ion] slybeans:
I'm noticing the .73 isn't actually giving better battery life and .67 was better, anyone else having the same issue?
[Sony Xperia S, Acro S, Ion] vitorugo-8:
same thing here
[Sony Xperia S, Acro S, Ion] Static-Noise:
How long have you had it flashed?

I gave in and flashed it tonight. Now, I've used it non stop with the screen and internet on playing Draw Something and its dropped, understandably, however I do expect it to improve, as other users are saying.
[Sony Xperia S, Acro S, Ion] wing_zero8556:
I can confirm that after removing com.SonyEricsson.android.wakeup standby battery is way better. Freezing the app does not work
[Sony Xperia S, Acro S, Ion] Static-Noise:
Better than updating to .73? What version are you on now?

What does the app do and what impact does it make on the phone (like, what do you lose by removing it)?
[Sony Xperia S, Acro S, Ion] bustervic:
Is there a negative to removing this process?
[Sony Xperia S, Acro S, Ion] shmoejoe:
It could have just been a weird setting I hit, but when I froze it (better not remove it) it stopped my mail syncing and such when my screen is off. I have it unfrozen since .73 since it fixed the battery issues.
[Sony Xperia S, Acro S, Ion] NightSky256:
That service is for wake up the phone from deep slee, to sync email, what'sapp, ... and all those services whose requires to connect to something and pull something...
[Sony Xperia S, Acro S, Ion] wing_zero8556:
Nothing that I've noticed so far. Whatsapp still updates and everything. Now my screen on and awake bars are equal, before my phone was awake even when the screen was off. I don't have email syncing so I'm not sure if it affects that.

Also I'm on .73
[Sony Xperia S, Acro S, Ion] superlimau:
i doubt so. the awake service is for fast dormancy and got to do with network switching. my facebook, email and twitter notification still function normally after uninstalling it.
[Sony Xperia S, Acro S, Ion] olaf63:
I just finished second charge with .73 firmware the phone died after uploading screenshots and writing this post so another 15min. of screen on

for the whole time 3g or wifi on and mostly surfing the web following 5 forums at the same time.

with next cycles of charge with this rom I expect further little improuvement duebto battery calibration.

satisfied and tired now

ciao
[Sony Xperia S, Acro S, Ion] Efe64:
Woww 5 hours use??

My battery gets like 60 70 iff i use it for 1 hours..

Bright at 30
[Sony Xperia S, Acro S, Ion] Static-Noise:
Just discharging on cycle two.

Not great, but Draw Something, which I gave into and tried out, seems to be an absolute battery killer, especially with the flashy screen.

That said though, on .73, not too promising so far, but expecting better as charge cycles go, I hope.
[Sony Xperia S, Acro S, Ion] olaf63:
I suspect that this was easy with most wifi surfing, 3G surfing the web would have lasted surely less, but in this day 3G was on in my office

along 7 hours with syncing activated ad also a little web browsing. Next try will be with only 3G web browsing, let'see but I've the impression that the very good reception and HSDPA speed have a negative impact on battery.

battery indication is somewhat unlinear and I noticed that the first 10% (to 90) flies away, then this behaviour slowly changes until the mid values and from that seem to last more until discharge. Also this can change as this rom was at the second charge cycle, with next maybe battery indications will be more precise.

Another reason of unlinear discharge could be the type of battery used by Sony, because this phone has greas charging times with all charging systems, not only EP850 charger and this could be due to battery type used.

how you charge your phone when you bought it> wait to down all battery to turn of your phone then charge it or directly charge over the company charge?
[Sony Xperia S, Acro S, Ion] del1701:
Looking back over this thread I'm thinking of flashing back to .67 UK generic from .73 SG, the reason being is that at the moment on.73 I'm getting really good battery life but I'm not sure if it's the firmware or weather I just needed to wait a little longer for the battery to settle down, what do you guys think ?
[Sony Xperia S, Acro S, Ion] mastrEST:
Well if the improvement came quickly after the upgrade then it should be the FW and not battery settling in :P

My 73 FW has really improved the battery life. 20% with around 11 hrs of medicore use. Before upgrade it would have drained almost 50% by now.
[Sony Xperia S, Acro S, Ion] del1701:
Maybe it was just wishful thinking on my part :rolleyes: best I keep. 73 for the time being until I can get an official uk. 73 :D

It's so easy to swap official roms, why not trying, but it's also difficult to make battery comparison. I dunno if there are apps for that..
[Sony Xperia S, Acro S, Ion] GT35pro:
I can confirm that battery life is no longer an issue after the .73 update. After 24 hours with moderate use, i still have 36% battery left.
[Sony Xperia S, Acro S, Ion] doministry:
waiting for this upgrade than.
[Sony Xperia S, Acro S, Ion] Static-Noise:
Give it time, or flash now.
[Sony Xperia S, Acro S, Ion] :
give it some time

and my 3rd sxs ahad 16h of use ater first charge

and after the 73. fw its holds for a day and a little bit more while it on wifi whole time an auto synk hotmail gmail and it was on auto gsm/wcdma

thats good for me :D
[Sony Xperia S, Acro S, Ion] necrohiero:
Well i am using .73 and while hearing music all the time from it.. I felt it took longer for it to reach 20% of batt live, but still not long enough to say that it is a satisfying change..

Ok tough. But that's probably because I have many background apps running..
[Sony Xperia S, Acro S, Ion] mateusz243:
My battery lasts for 2 days now after installing .73 and I'm using it alot. Listening to music using the internet playing games downloading new apps etc and the phone drains only about 4-5% of battery over the night. On .67 it used to drain up to 25% and battery used to last for half a day maybe :)
[Sony Xperia S, Acro S, Ion] randy_c:
Sorry I posted another one but mine was very strange. I charged my phone 100% then unplug. Press power+vol up till vibrate 3 times and charged it fully. Turn the phone one and it was down 96% and charged till 100%. again power+vol up till vibrate 3 time to charge again but it only show 3/4 charged... I keep doing it till both showing 100% but I can't.

I think battery stat is the prob on mine...
[Sony Xperia S, Acro S, Ion] mister-g1:
I noticed that my phone doesn't stay in deep sleep mode all the time while the display is turned off. After two hours CPU spy recorded one hour of deep sleep and one hour with 345mhz. So some process is wasting energy. I have auto sync on and email check every 30 minutes. The only active push service is whats app. Uninstalling this had no difference in battery consumption. Any ideas what can cause the deep sleep not working? I'm on .73

Battery Life

Sent my Xperia S to Sony, upgraded to Build .73, and battery life is good now. It can last more than 12 hours with 30% left with 3G, phone calls and occasional web surfing..
[Sony Xperia S, Acro S, Ion] dixter:
Just switched to .73. Do I still need to force GSM-only or WCDMA-only or does this firmware fix the drain caused by switching between the two?
[Sony Xperia S, Acro S, Ion] Dianish:
As long as you keep using wifi, 3g and what so ever you give it full throttle and ofc it will drain the battery. After mentioning my own issues in this topis my battery life have been improved much. Keep lasting about a week with my regular texts and call, but mostly playing music. Im not a heavy user, but what to expect? Its a new technology that requires lots more power than we are use to see and therefor will drain battery faster and i can make it last 2-3 days before it reaches 5% battery alert which is when i plug in the charger.

Wifi and 3G is the biggest sinner everytime i think of turning it on, boom my battery starts to drain. Been like that on the rest of my androids. If turned off, no problems at all.

Its like, you got this new car, which was told from factory it would drive X miles each gallon, but if you turn on the A/C, the radio and using servo for stearing, you wont even get as far as the factory told was possible.

We are only in 2012 and the phone by its date is actually really good. It will get better in time, but not as much as many of you guys wants it. Its sad, yes, but still, we're only in 2012 and developers of technology still got much to learn.

Have patience :)
[Sony Xperia S, Acro S, Ion] DarrenCarol:
So here's my little list of things I've been doing do improve my battery life:

Uninstall Apps I'm not using (I'm now rooted and this includes bloatware).

Adjust brightness using a widget to the minimum level possible that is comfortable to see.

Switch to 3G only as I live in a good 3G coverage area.

Disabled auto-sync and background data (except for when on play store).

I restart the phone once a day, usually last thing at night.

Disabled vibration

Turned off noise reduction

Put my phone into airplane mode over night.

Am using minimal amount of widgets (circle battery and the time are the only two I have active)

Total up time from 100% to phone shutting off: 2 and a half days :)

Was originally getting about a day from out of the box state.
[Sony Xperia S, Acro S, Ion] PhilAd:
i cant see much difference to other 1280x720 devices ... reaches from morning till evening, except when i am excessive gaming, but thats a problem with all smartphones.

i do not turn of anything, always syncing using all networks edge/hspa/wifi also bt in car, whatsapp facebook messenger, etc., etc. ... no other problems than other people with their smartphones or with the phones i had before. for my sgs2 i bought the 2000mah battery to have it running the whole day so it should be even better now with 1750mah.
[Sony Xperia S, Acro S, Ion] zarg2:
Quick question to those who have their battery settled.

In the info menu (*#*#4636#*#*), battery info, voltage, what value do you have when fully charged ?

After 2 full charges (Not exactly, I'll explain below *), I (only ?) have 4202 mV.

I'm asking because my old Desire (1400 mAh) showed 4197 mV, so I thought a 1750 mAh battery would be higher.

* The problem is when the green led shows, after charging, the charge level is @ 91%. If I let it charge until 100%, the voltage is not different. Don't know what to do.
[Sony Xperia S, Acro S, Ion] PhilAd:
why should the voltage be different?!
[Sony Xperia S, Acro S, Ion] adam1000rr:
I flashed .73 a while ago but it didn't change much battery wise..

I found out com.sonyericsson.facebookcalendarsync (sorry, can't remember the exact name) was still draining my battery.

Deleted it with Titanium Backup and now I can go through a whole day without having to find a power source! :D
