I have the same issue and wondering if it's mean the battery is a 1500000 or a 1750000 at the end
[Sony Xperia S, Acro S, Ion] badriniki:
hmm, personally i don't have any problem with the battery

2days 22hours 24mins of usage and 42% of battery still left.
[Sony Xperia S, Acro S, Ion] FenrirMX:
I flashed the central Europe FW yesterday as found it to use up my battery even faster than my old one (.67)

Only difference was that it was the cell standby instead of the screen that was the culprit.

So I switched to the Norway generic one, but I'm honestly nit setting much change.

Should I wait it out our just resign myself to recharging every day with moderate use?
[Sony Xperia S, Acro S, Ion] awf:
5 days on .73 NL generic firmware and the battery is adjusted and amazing 1d and 7hrs and still 24% battery left :D:D:D
[Sony Xperia S, Acro S, Ion] feadurn:
And how long with the screen activated?
[Sony Xperia S, Acro S, Ion] awf:
Well I don't know at this point just recharged my phone only it's based on my normal usage from the past 6 weeks with .62 and .67 firmware and two different phones ;-)

Which was always between 14 and 17 hours...

[Sony Xperia S, Acro S, Ion] doministry:
Like me exactly.
[Sony Xperia S, Acro S, Ion] Dyflinn:
;D

I noticed that the SystemPanel App was showing 4200 mV and 0% charge. I then discovered on the Android Forums that 4200 mV was a full charge. So it seems to be a calibration issue. This would explain why the phone didn't charge over the weekend because it was already fully charged, despite the 0% reading.

So I unpugged it yesterday and, ignoring the red light, have been using it since. I did the Repair Phone option via Sony's PC Companion in the hope that this would reset the counter, but no luck there.

I've had to reboot it a couple of times when the screen went into hibernation and wouldn't come back on visibly, but it's still on now. It was only down to about 4000 mV this morning so I've put on Bluetooth, WiFi, GPS, Full Screen Brightness, Autosync and Live Wallpaper. Now at 3666 mV.

I'm expecting (hoping) for a power down at 3600 mV, as that is the effective level for a full discharge. Then I'll recharge and hopefully the charge level value will be back in line with the actual charge.

Not sure how it got messed up to start with though.

This method make the battery worse ! It's suck battery badly, better leave build.prop alone.
[Sony Xperia S, Acro S, Ion] dthomasen:
The default launcher (from sony) on my device was sucking the life out of my phone.

Installed Zeam launcher (Really lightweight), and now I'm seeing way better battery life!

Having the same problem man...bettery 100% b4 going to sleep

when i wake up and check my phone the battery is about 40% 50% without using it..lol wtf this is a big problem

Got 15hrs today...

Guys,

I got 15hrs on battry today.... From the day i bought Xperia S, it started off with very bad battery life... but after a couple of weeks it started picking up and slowly from 12, 13... it gave a max of 15hrs on battery today. Check screenprint attached;
[Sony Xperia S, Acro S, Ion] gm007:
If I am not wrong yesterday you said you have fw.62 and you have notification about fw.75 update.

So update it and you will see a good improvement in battery.
[Sony Xperia S, Acro S, Ion] georgebest:
You must have some applications running on the background or else you have a problem. My device 100% b4 going to sleep, after 7 hours 95% in the morning. GSM network only.
[Sony Xperia S, Acro S, Ion] Dyflinn:
So I finally got it down to 3200 mV (not 3600) and it powered off. It took about 30 hours!! The last 10 of which I had all the guzzlers on. And the whole time it read 0% charge, red light, red battery symbol etc. Patently the battery had a good charge on it despite the reading.

So I plugged it in last night at about 10pm. Next morning, the red light is still on. Unplugged it to come to work and plugged it in again. It's now in a USB port using the supplied cable and the red light is on (no Orange). Still reads 0%, though it is charging.
[Sony Xperia S, Acro S, Ion] avexdevil:
Got 25hrs with light to medium usage in the first week I used this phone on 73 firmware.. Stock launcher, am using juice defender now to see if I can prolong Batt Life.

What is your battery drain rate in games? Mine is about 40 min. of gaming == 30% of battery off....
[Sony Xperia S, Acro S, Ion] eugenius8:
it depends on the game, ive tried out temple run (3D) on average drains one percent per minute :S with drag racer (2D) drains just over one percent per 2 mins..

on firmware .67 btw
[Sony Xperia S, Acro S, Ion] naughtb4:
Going to try this as well

What sort of improvements are you seeing?
[Sony Xperia S, Acro S, Ion] dthomasen:
Before I got ~10 hours of battery, now it's more like ~20.. :-) Think maybe that mine was a special case, but thought I would share it :)
[Sony Xperia S, Acro S, Ion] naughtb4:
Cheers seems a bit better on mine as well, esp when the screen is off.

Although with the moving to Zeam I also removed a number of widgets that may have been affecting battery

Still 7 hours in and only 20% battery gone aint bad :)
[Sony Xperia S, Acro S, Ion] sssache:
After one month of use the battery has become very very stable. With a medium use i can do 48 hours easily. This smartphone it's getting better every day...

Battery draining on Xperia s (FW .62)

For my XS (Firmware .62) the only solution to decrease the battery consumtion was to deactivate 3G. Now the battery-life increase from 24h to 72h.
[Sony Xperia S, Acro S, Ion] GT35pro:
Go SMS pro is a battery hog. The moment I installed it the battery life was halved. After I un-installed it, everything went back to normal.
[Sony Xperia S, Acro S, Ion] Eyados:
turning off the BT, Wifi, and GPS is not enough

you have also to:

turn off the NFC, Bravia engine, rotating screen, and remove live wall papers.

and the most important point is: keep your battery temp below 30 C deg.
[Sony Xperia S, Acro S, Ion] FenrirMX:
Wouldn't it be easier to just turn the phone off if you're gonna do all that?
[Sony Xperia S, Acro S, Ion] Scratchling:
Hmmm, time to chime back in on this methinks.

First off Zeam seems nice. I like being able to increase the rows x columns in the app tray. Initial issues: stock SE clock(Which I like) is incompatible. As is the recent media thing, and the stock music widget. Also, the folders arent as nice, but I could deal with that.

In all in anyways, my battery life is ok as is, on .62! But I'm wondering about a few things:

Does NFC burn a significant amount(I suspect not, as its only on while the display is)?

Does the bravia engine burn batt(and is that a cause of delay when opening photos)?

When you're at home, is disabling HSPA and enabling wifi a good trade off? The GSM aerial is still active for phone SMS and wifi always seems to gobble up charge.

Display is always ~65% of my power usage, thats ticking over at 30% backlight, what is everyone else seeing/using in terms of the screen?

TIA,

Scratch.
[Sony Xperia S, Acro S, Ion] Static-Noise:
Firstly, NFC does seem to use a portion of battery. Not a lot, but not nothing.

Secondly, I'm the same with the display usage. It is highest, followed by standby for the signal and network.

As for data at home, I read that data on the move is the best option, but to only use WIFI if constantly using it or downloading heavy content. Do vice versa for 3G.

HTH,

Static.
[Sony Xperia S, Acro S, Ion] del1701:
With all the .73 firmwares around, has anyone from the uk who flashed to .73 flashed back to .67 uk generic ? and if so did you see any difference in the battery ?
[Sony Xperia S, Acro S, Ion] Pezo:
Doesn't the phone shut down the data connection anyway if you enable WiFi?

Sent from the Delta Quadrant using a transwarp conduit.
[Sony Xperia S, Acro S, Ion] anthon:
I'm on my first charge, with .73 firmware, 13 hours and still 47% remaining.

I don't see any differences about battery comparing it with my xperia Neo
[Sony Xperia S, Acro S, Ion] Static-Noise:
No, it still keeps the data on and running (as in open and available), but uses WIFI for the main provider of Internet. As far as I know for example.

On a side note, I have this at the moment. I deleted android.wakeup, removed timeline and others. Very happy so far.

Oh, and that's 75%! 75% left!

.73 frimware

have you tried app blocker on the play store, install it and set it up to block the games you play that dont need access to the internet, i use it on alot of my games and ive seen a huge improvement in battery life because its not continuously bringing up different adverts ingame,

its also nice to see the whole screen aswell instead of a portion taken over by "download xxxx today""" :)
[Sony Xperia S, Acro S, Ion] adsada arc:
I had a read here for some tips: http://www.sonymobile.com/gb/suppor...how-can-i-maximise-the-battery-performance-1/

it says:

"Charge your phone often. This will not affect the lifetime of the battery."

But I always assumed that if you keep topping it up and keeping it charged, it damages the battery..

can anyone confirm??
[Sony Xperia S, Acro S, Ion] ntduyphuong:
Li-Poly batteries allow you to charge it anytime, no need to wait until it's completely empty. But, you should charge when it reachs 20% or below :)
[Sony Xperia S, Acro S, Ion] milton.bain:
full data usage, full gaming,40 minutes of Talk time and normal usage....still at 7%

superb battery!!!
[Sony Xperia S, Acro S, Ion] dixter:
I haven't really noticed the improvement that most people have noticed between .67 and .73 and in particular I was concerned about the awake time of my phone last night. From the last time the screen was on, I didn't touch the phone, and yet it woke up for reasonably long periods of time overnight. Does anyone know how I can find out which app is waking it up in this time? I've got Llama installed which automatically turns off Wi-Fi overnight, but could it be Llama itself causing the problem?

I've used the following, with less than impressive results:

Currently running NL Generic .73, it's behaving much better.

[Sony Xperia S, Acro S, Ion] FenrirMX:
After doing some maths I've been running for over a day and I still have around 30% charge, so it would be fair to say the NL generic firmware is doing its job.

Mostly on Wi-Fi, a couple of calls, Whatsapp, some games, a couple of youtube vids, some browsing...

Lol

After seeing all that, I guess I'm very satisfied with this firmware.
[Sony Xperia S, Acro S, Ion] DevilsArc:
I turned my WiFi off yesterday, and used very little 3g. I didn't charge last night or today, have done a bit of surfing but not much. It seems all of a sudden the battery had sorted itself out
[Sony Xperia S, Acro S, Ion] starok:
I turned wifi off last night and instead of dropping 20% overnight I only lost 5%.

That's weird, it looks like there's a problem with the wifi, it souldn't suck so much battery in standby mode.

I'm running FW France .73
[Sony Xperia S, Acro S, Ion] dixter:
Per my last post, I lost 9% of battery in about 8 hours overnight with my phone in airplane mode. It also showed as being awake most of the night. Is this normal?

Wake lock

As someone mentioned (cant remember who) i downloaded, badass battery and CPU Spy to monitor the Wake-locks.

I unplugged my phone last night before going to sleep and heres is a couple of stats after 12:30 hours on battery:

time at 1.5Ghz: 48 minutes

time at 384: 2 hours 45 minutes

time in deepsleep : 8 hours 30 minutes

wakelocks:

com.sonyericsson.android 3897.0

google maps 4124.0

android system 7587

Is it me or does that seem rather excessive?
[Sony Xperia S, Acro S, Ion] Pezo:
My phone is now 16h 28m on battery and I don't have nearly as many wakelocks as you do:

Maps 999 (11m 15s)

Android System 172 (31m 19s)

Google Services 71 (3m 23s)

That's with use mind you...

I've never had more than a couple thousand locks from Maps, but I think they are very brief.

The clock stats also look different for me:

1512 MHz: 25m 03s

384 MHz: 1h 27m

Deep Sleep: 13h 59m

battery life improving

Hi,

After almost a month purchasing this phone I can say that battery life has improved also would like to mention that i'm still on .62 FW. Today I used internet radio for the whole day and the results of battery are good still 13% remaining :-)
[Sony Xperia S, Acro S, Ion] dclark16:
I could understand if i'd been using the phone, but the fact is it was on my bedside table for 6 hours while i slept :P

I tried Xperia S today

Had it in hand at 100% Battery

Just got it 5minutes making random stuff (photo, sms, nothing special), then Battery was down at 94%

more than 1% a minute

If you dont do anything it will last 2 days.

Ive come from a Defy that went 5 days on standby providing you didnt do anything but you can buy a £5 PAYG phone to do that.
[Sony Xperia S, Acro S, Ion] AnubisNefer:
Did you by any chance look which firmware it was? .67 or .73?

.73 firmware boosted my battery life substantially, even with autosync and 3g i would last more than a day.
[Sony Xperia S, Acro S, Ion] Static-Noise:
.73 Singapore stock (originally an Irish generic).

Rooted, removed bloatware.

Deleted wakelock.

Deleted Xperia Home.

Deleted most Sony apps.

Deleted Ant+.

NFC off (didn't need it on for my needs)

Data on every 30 minutes.

Push and Pull data.

Seesmic for Twitter. Gmail. Beautiful Widgets. Path.

Using Zeam launcher.

Using Juice Defender Ultimate.

Dropped CPU speed by one level and one SmartAssV2.

Airplane mode at night.

Fairly happy.

Here's my record in battery life with .73 for Poland, forced 2G, bluetooth was on almost all the time except nights. Phone is not rooted so all the junk apps still running, including the wake process which keeps my phone active even at nights, but I think I'll wait for root possibility without unlocking bootloader, or some unofficial way to unlock bootloader (don't want to void warranty). The battery is not that bad if You don't use display for long time, cuz it sucks juice like crazy.

Between 0700 and now 2400, so 17hrs, I still got few percent left. I want phone to switch off itself, so I can charge it over night fully for good few hours.

I've reflashed it, removed all apps that i dont use, updated all apps that needed updates from market, wifi off, bt off, screen on lowest, no sync and let it rest for 6 hours and see what happens. It's not the battery it's an app that keeps the phone awake.

my xperia s in flight mode standby and normal standby

Hi, guys. I am giving my test of my xperia s battery!

After a fully charge, I left the xperia s in flight mode and standby for 14 hours and battery comes to 94%. Then, turn off flight mode and turn off both wifi, bluetooth and 2g/3g. After another 9 hours standby, battery drop from 94% to 69%.

The detailed battery usage is shown in the picture. I am quite concern about the "android system" which drains 36% of the total usage, and it was awake for more than 3 hours. I think it should be the main usage during standby.
[Sony Xperia S, Acro S, Ion] GalaxyS2R:
Right so today I have made a 10minute phone call

[Sony Xperia S, Acro S, Ion] Korumera:
Well here is mine test:

It's been off for 6 hours, 1 call (2 minutes) and that's it, if you look at the awake something is really keeping it up.

and this is what battery says:
[Sony Xperia S, Acro S, Ion] Razje:

[Sony Xperia S, Acro S, Ion] deanfield:
You are facing the same problem with me I think. Your standby usage of "android system" is even higher than me.

If the phone can last a day with whatever you consider normal use then that's about normal for smartphones these days. I change phones roughly every 6 month's and none in the last 3 year's have lasted me more than one day. They've all been high end phones too from HTC, Samsung, Sony and Apple.
