Hi !! I read all post on this thread but anything change my battery life. At the moment i charge my phone to 100% when he turn off itself, and i loose 3% in 5 mins !! :eek: i dispair !! i have my phone about 9 days with 5 full discharge to turn off itself and charge without running and the batterie life don't change or minim change :(

Édit : ok i freeze Sony....awake and when i go sleep the phone was at 100% and 8 hours later when i get up he loose only 3% :) i'm happy, it's not a battery problem. But i turn on my sreen about 5 mins he eat 4% :confused: i think the problem with battery life come from the sreen, now i'm not an expert and i hope it's an software problem and not a hardware problem :D
[Sony Xperia S, Acro S, Ion] Dianish:
Solved

My Issue has been solved.

Still the same config as last time, with the only difference i have installed ATK app. My phone stays in idle for 7 days before reaching 20% battery. When using the phone as a regular user it lasts 3-4 days - Amazingly enough.

20% Brightness.

Battery settled.

Not HEAVY used - More regular basis tested.

Only app installed is ATK - Advanced Task Killer.

No Wifi or sync activated(still dont use it, but during test i did)

Also Android version .62 still - So its not an software issue.

Followed all the advices in this thread... And now the battery life is fine.
[Sony Xperia S, Acro S, Ion] Efe64:
Ogw...

So which app is it? The battery drainer?
[Sony Xperia S, Acro S, Ion] Rami1987:
It is the wifi and data (3g or 2g) who drain the battery. If you manage to freeze the data while your phone is on sleep then your battery will more than doubled. I used two programs to do that and both of them did a great job.
[Sony Xperia S, Acro S, Ion] slybeans:
Wait WIFI drains the battery? That's absurd.
[Sony Xperia S, Acro S, Ion] osman26:
This is a joke right?
[Sony Xperia S, Acro S, Ion] Efe64:
Just gonna return this crap today.

Im gonna ask a new one. Hope that phone will be good.
[Sony Xperia S, Acro S, Ion] dibdin:
Don't hold your breath.
[Sony Xperia S, Acro S, Ion] andoridkiller:
I can defiantly confirm the wifi drains my battery when it is off it does not loose as much!
[Sony Xperia S, Acro S, Ion] 3Shirts:
Of course wifi uses battery. It is a separate piece of hardware as well as needing the OS to do a little extra work in scanning for networks when it's on.

Like everything else, if you want the battery to last a long time, turn off wifi or set it to idle when the phone is in standby.

You only need a little common sense to see that the more the phone is doing, the faster the battery will run down. If you turn off wifi, data, bluetooth and leave the screen off all the time then it'll last ages but then why do you have a high end smartphone?!

Strike a balance. I use tasker to turn wifi off at work since we don't have it there anyway and switch to 2G unless I'm browsing. Even with a little gaming and calls etc, it will easily last a day.
[Sony Xperia S, Acro S, Ion] Efe64:
This is ridiculous...
[Sony Xperia S, Acro S, Ion] osman26:
I have the same problem. Also bought it from the t-mobile site?

İt uses 10% per hour of the battery with normal use..
[Sony Xperia S, Acro S, Ion] Rashkae:
Root it and freeze com.sonyericsson.android.wakeup
[Sony Xperia S, Acro S, Ion] ergo14:
My phone uses about 4% per hour with network data and autosync on - with very light use.

less without data on, i had 25% of battery left after 26h since last charging ( turned data off for night)

This means to me that phone can last for day use with when charged over night and plugged off in the morning - i suppose this is acceptable for phone with screen like this.
[Sony Xperia S, Acro S, Ion] bustervic:
I just installed Juice Defender, I had used in the past with good success and it seems to be doing a good job so far. I'll post more results later.

Using this program, with the balanced setting I am still seeing updates when I need to and am at 3hrs and 91% battery with some surfing, twitter, and installing a few things.
[Sony Xperia S, Acro S, Ion] TheRafal:
I'm return :-D

Ok i make à normale day with wifi, data and sms/call and after 12h i have 45% left :) but it's right the screen use 65-70% and other less than 10%. It's right too, thé battery life increase with time after some day of use, but i think we can use it more times if thé screen not drain the battery ;)

On 12 hours, the screen was up only 2hours and use 64% :eek:

The screenshots was here
[Sony Xperia S, Acro S, Ion] Yakandu:
I see this on my device to... Screen is always ~60% :(

Is this normal?
[Sony Xperia S, Acro S, Ion] Scratchling:
720x1,280 and massive. What else would you expect?
[Sony Xperia S, Acro S, Ion] Yakandu:
Dunno, thats why i'm asking xD

Thanks
[Sony Xperia S, Acro S, Ion] del1701:
My battery was beginning to settle down quite well after having the sxs for a week but then yesterday it started draining really fast, then this morning after I took it off charge it lost 25% in 1 hour :-o and I couldn't work out why, then I remembered that on saturday night I had started playing around with google+ so I signed out of it and low and behold my battery is back to normal now so for me this is the rouge app that drains the hell out of the battery, here's a screen shot of my battery stats after I have used my phone today for a couple of calls which were quite long and via bt connected to my car, texts, camera and internet with WiFi and data.
[Sony Xperia S, Acro S, Ion] Evil_Sephiroth:

[Sony Xperia S, Acro S, Ion] mmarekk11:
Hmm almost 2 days and battery still on 70% i suppose.. that is great, i havent seen so good battery life on XS so far. Do you use stock battery? :D
[Sony Xperia S, Acro S, Ion] Efe64:
2 days???

Please tell me that yiu guys are kidding...

I cant use it even for 12 hours :s
[Sony Xperia S, Acro S, Ion] mmarekk11:
Look at the attachment in the last post of the 34th page.
[Sony Xperia S, Acro S, Ion] keithwalton:
Wifi does seem to be the major smoking gun, my old sgs used to have an odd feature that setting the wifi to 'always on' used less power than having it set to only on with screen on.

26h of medium use and I have 70% remaining today.

Previously with wifi on and minimal use and it was flat in 20h.

I hope sony will implement deep idle into there kernel code rather than just plain idle.
[Sony Xperia S, Acro S, Ion] gm007:
The screenshot shows that he barely use his phone.
[Sony Xperia S, Acro S, Ion] Nimche:
Some get good battery, some don't. there are 35 pages of good info which I wish they were consolidated all at first post.

I have rooted .67 with most of Sony stuff removed. Don't have facebook or anything else.

All I do, is

GPS on(for location of weather app)

Screen brightness is at 40%

mostly connected to Wifi

phone mostly is sleeping

Bluetooth is on

3 Email account sync is on (all PUSH)

Gmail sync is on

afew short phone calls.

After 8 hours I am about 67% left.

It gets better overtime, and requires some patience. after all this is dual core with a nice screen.

Thanks for people here for their inputs.
[Sony Xperia S, Acro S, Ion] Rami1987:
Look at my screenshot below and it shows that I use the phone frequently and yet manage to get more than 2 days with the help of a program who turn off WIFI / Data when the phone is idle.
[Sony Xperia S, Acro S, Ion] Efe64:
Atk agressive when screen off?

What do you mean with that? I dont get it...

Yeah I know atk is for advanced task killer

Btw where is the next update? Everyone stopped talking about!?
[Sony Xperia S, Acro S, Ion] bazooka_joe:
There's an option to kill apps safely aggressive or crazy in atk
[Sony Xperia S, Acro S, Ion] eddyedwards007:
I noticed yesterday that while I was using the phone, that is on the internet, my battery was actually draining while on charge, has anyone else had that? I was on 100%, the screen was on full brightness and I was basically reading posts on xda and surfing the net.

I've never had this before on my hd2. The funny thing is I watch full length films on it with full brightness and it never runs out but as yet I haven't checked what the battery is doing when I'm watching the film. I didn't think it could do that while on charge?
[Sony Xperia S, Acro S, Ion] gm007:
That's normal cause the consumption is more than charging power, and especially if you use pc charging not the AC charger.
[Sony Xperia S, Acro S, Ion] HellLight:
I have this phone for about a week now and it does exactly the same thing. Battery goes from 100 down to 80% in around 5 hours without using it. Data, gps, wifi, bluetooth, sync is all closed. The only thing that worked for me is to put it manually in gsm mode rather than wcdma preffered/gsm. The difference is huge. Now it drops less than 1% per hour.
[Sony Xperia S, Acro S, Ion] gm007:
Yes I can confirm that + upgrading from 62 to 67 gives a huge difference.
[Sony Xperia S, Acro S, Ion] Evil_Sephiroth:
Normal use...if need 5 minutes to check my email phone doesn't show gmail or other app in the graphic
[Sony Xperia S, Acro S, Ion] eddyedwards007:
I was on AC charger and I don't have anything syncing its all manually done, I'm also on 67 firmware.

Ah well if that's normal, so be it! :)
[Sony Xperia S, Acro S, Ion] Evil_Sephiroth:

[Sony Xperia S, Acro S, Ion] sssache:
The battery is getting better and better. It's seems that the battery needs some recharge cycle to stabilize.
[Sony Xperia S, Acro S, Ion] MrZippo:
Yes I can confirm that my battery is getting better and better too.

I can now get about 26hours with wifi always on.
[Sony Xperia S, Acro S, Ion] shoz_on4u:
Pls provide screenshot of your battery usage will be really helpful for us to decide whether to go for the device? Thanks in anticipation.........:)
[Sony Xperia S, Acro S, Ion] robiceli:
.73 firmware update is available for the S!

Yesterday when I connected my S to my PC, PC Companion notified me about a new software update being available. I updated from .62 to .73. The strange thing is, I never got the .67 notification as I read some of you guys updated to that fw already. Anyway, my phone is unplugged for 14 hours right now, I've sent a few texts, had 3 short calls (for about 14-16 minutes of total calling time) and I still got 81% left! Before I couldn't even get to 6 hours without having 70% (or less) even if phone was on idle most of the time.

I think and hope that the .73 update solved the battery drain issue once and for all. It looks very good so far!
[Sony Xperia S, Acro S, Ion] iamelton:
im still on .67 and i think it already improves the battery performance a lot..

used the phone for about 2 weeks now, and in the first 3 or so days (when on .62) the battery performance was really unacceptable (e.g. 20% drop overnight with no wifi, gps or bluetooth, and 3g on), while in the recent 10 days (with .67) the battery got very stable behaviour..
[Sony Xperia S, Acro S, Ion] MrZippo:
Here you go here is a screenshot of my battery usage on the Xperia S
[Sony Xperia S, Acro S, Ion] ssj_jaypee:
Lstill on .63 however battery life has improved greatly since I first got the phone.

Can't wait to get home and upgrade to .73
[Sony Xperia S, Acro S, Ion] Static-Noise:
Mine has been atrocious since day one, and I'm not happy. Any days that it has been acceptable, it's rubbish the next. It's a pity, as I love this phone.

I'm calling the store today as the salesperson got his the same day. I'll ask how his experience has been. I picked this after advice and price point versus a Samsung Galaxy SII. Now I regret it.

I'm on a generic world version at .67.

I've got Juice Defender Ultimate running, no music or other apps, ATK killing at screen off. And, not even heavy use since the battery life is so bad.

Yesterday, for some reason, Media Server ate 30% of my battery and I wasn't even watching movies or playing music. It's a joke of a phone with this problem, especially at this price and since being the flagship device.
[Sony Xperia S, Acro S, Ion] shmoejoe:
Updated to .73 and it appears to have improved my battery life quite a bit...

I will watch it, but I have been doing rather decent use with wifi and 3g on ( read: texting, installing, removing junk apps from flash, light gaming) and I'm only dropping like 1% an hour or so it seems D:

at the end of the day I will screenshot my usage, but so far I'm happy. :)

EDIT: It's been 6 hours and it's down to 70% but I was sitting at below 90 after flashing and I have had some pretty modest use out of it. Due to the fact that It didn't register my battery at 100% I won't screenshot it. So I will start from tomorrow really monitoring the battery, but currently it is indeed getting better life :) I think if you arent messing with it the entire day, you could get a full day easily. Heck, I got a full day with .67, so this is just fantastic to me :D
[Sony Xperia S, Acro S, Ion] stoyan25:
Can you please tell me how to make the udpate to .73 when I use the SOny PC companiaon it doesn't require and udpate. ??I have serious problems with my battery - 4-5 hours with 3g and battery below 30 %..bad :(

anyone help ?

[Sony Xperia S, Acro S, Ion] deanfield:
Hi, everyone. I just have a worse finding about the battery of xperia s.

The day before yesterday I fully charged my xperia s to 100% battery and then I COMPLETELY POWER OFF the phone.

This morning (after I power off the phone about 35 hours)when I turn on the phone, ths battery is only 93%!!!

Could this be a hardware problem?! I've seen the same case from a Chinese android forum which says that 10 hours power off drain 4% battery.
[Sony Xperia S, Acro S, Ion] georgebest:
It happened to me too. After powering it off for seven hours, the battery was at 97%.
[Sony Xperia S, Acro S, Ion] deanfield:
I am worried that this should be an hardware bug! I understand that any battery has a every slow discharging even it is not been used, but never can be this fast!

I also tried my old samsung i9000, after I power off it for about 10 hours, the battery drains nothing!
[Sony Xperia S, Acro S, Ion] shmoejoe:
-snip-

My point was addressed in the previous post about batterys discharging so I edited to remove it :P

/ignorethispost
[Sony Xperia S, Acro S, Ion] keithwalton:
I wouldn't worry to much about the battery appearing to discharge whilst the phone is turned off particularly at the high charge %.

I would suspect your battery isn't fully calibrated yet and that the change in % could be a whole load of things, for one the battery would of cooled down in that time altering its state.

When I used to 'wipe battery stats' on my i9000 i used to get quite fluctuating battery %'s I could reboot the phone and loose 10% battery charge.

Even unplugging the charger when it said it was full could drop it around 10% plugging it back in would allow it to charge further.

As people are commenting the battery seems to be improving a lot with a few charge / discharge cycles
[Sony Xperia S, Acro S, Ion] Scratchling:
Yeah, as above this is normal. Especially with a new unit.

Remember that cells in a sense work by being pushed out of their comfort zone. A 3.7v cell is EMPTY at 3.7V and charged at about 3.9V, you dont go down to "0" as some might think. The further you push a cell the more it wants to return to normal, so for the top percentage to be lost quite quickly is fine.

Performance also varies on temperature, if it happens to be a cold day battery life can take a big hit(Not 100% on li-ion but I assume its the same to lesser/greater extent than legacy style packs).
[Sony Xperia S, Acro S, Ion] NightSky256:
.73 forced (tft) update, and the battery now is much better !

don't worry about powering off and on after hours with battery decreased.

battery stats are really strange on android... i had some strange behaviors also in my previous i9000 so i stopped thinking where is gone 3% or where is come out +10%...

also wiping battery stats won't help! it's just a "mental saw" (italian way to tell it's a problem only in mind...)

Software fixes, expecially kernel power governor tuning, will increase battery life.

let's hope that new kernels in 4.0.4 (with the power management fixes made in kernel) will improove battery life...

try to hold the power button and +volume until the phone shuts AND has vibrated 3 times..release those buttons, turn your phone on then recharge and see..apparently this has worked for many people;)
[Sony Xperia S, Acro S, Ion] Static-Noise:
What is this for?
[Sony Xperia S, Acro S, Ion] iamelton:
someone described this as "calibrating the battery"..

and it seems to make the battery to "reset" to the supposedly 1750 mAh capacity..

the checking is via the "*#*#7378423#*#*" call sequence followed by some screen clicks..

judging from my tone u should realise that i really doubt if this calibration is useful at all..

if the battery can be calibrated in this way and immediately be boosted in capacity, why is it not done during production?

is this something like "overclocking" the battery then?

thus though my bettery reported 1695 mAh, i didnt do the calibration..
[Sony Xperia S, Acro S, Ion] lamplighter13:
I have been reading this entire thread and I have a suggestion which is more sensible that many I have read here;

To massively increase battery life hold the phone in your left hand and a live rooster in your right while there is a new moon.

Dance around a fire started with branches from a Pohutakawa tree while barking at the new moon.

This should work as well as many of the responses I have read here.

What the best way to charging? Turn off power to charging or charging when power on.

I appear to be losing 1% per hour on standby whilst at work in locker, also Angry birds space took a whopping 9% from 100% after a few minutes play.

6.0.A.3.67
[Sony Xperia S, Acro S, Ion] pennzoilgtr:
ok guys, at first i got like 20% + loss just over 6 hrs of standby so what i did.

1. factory reset, excluding internal mem.

2. completely remove any apps that came preinstall with it. through settings/application/manage apps. (at this point of time make sure charger is not plugged in, then carry on to the next step)

3. shutdown completely and let it charge till battery is full for about 2hrs while phone remains turn off. and then turn on normally while charger is still plugged in.

4. install back apps that i need.

and viola! i just did a full charge yest. unplugged it went to bed after 8 hrs later. woke up and batt level is at 93%. ;)

ps: i did not do any calibration at all by completely empty the battery. and just one try and it works magically.
[Sony Xperia S, Acro S, Ion] Felimenta97:
Every phones needs about 5 charges to set the battery down... When I bought my Xperia X10 MP, the battery lasted only 3 hours (of course, it was my first Android, I wa installing apps like crazy, and didn't knew battery saver tips... Now, with ICS installed, it can lasts from 8 to 14 hours, depending on use...
[Sony Xperia S, Acro S, Ion] shmoejoe:
Okay, battery usage today....

over 12 hours, with gaming, wi-fi on, and installing and surfing rather steadily throughout the day i'm sitting at 22%.

with the amount I used it today, i'm still rather impressed. It can only get better with time, I only gave it a decent charge last night, now I think I will let the battery get nice and low and charge it again :D. I'm already getting better battery life than my X10 with the amount i'm using this beast.

So no complaints from me :) still loving this phone.
[Sony Xperia S, Acro S, Ion] doministry:
I still feel it's not that good here.

Especially if it sucks energy on idle.

Intriguing. The phone is brilliant though.

Seems better today actually....

From 11 am to now - midnight - still 45% left.

How can people even whine about a smartphone that they didn't even have for a week.

Sounds to me like those people just don't know **** about li-ion batteries and how Android calibrates.
[Sony Xperia S, Acro S, Ion] doministry:
Hmmm. LiIon batteries are supposed to work out of the box, right?

And what do you mean by Android calibration?

I mean it's great our devices will just get better, but maybe I don't get it.
[Sony Xperia S, Acro S, Ion] Razje:
The percentage that android show's is just an indication.

This gets better over time, and after several charges.

It takes atleast like a week or 2 before android gives a good indication.

For this same reason, people wipe their batterydata after they flash a new rom.

So that it doesn't give a false indication of the battery percentage.
