In the space of 3 hours phone went from full charge to 85% with no use other than one alarm going off.

Turned it off and charged for an hour and a half. Turned it on and checked the battery and it was sitting at 96%. Plugged the charger back in and it shot straight to 100%.

I have a feeling it is reading the battery incorrectly. If this is correct, it is the same issue that happened on my Xperia X10 about 2 and a half years ago. You would think they would have this sorted out by now.
[Sony Xperia S, Acro S, Ion] 18lama:
If your phone is not sleeping leave the wifi on, I kept it running for 7-8 hours continuously at night and when I checked the phone had been sleeping for almost the entire time with only 2-3 or so wake events.

My phone used to sleep better after I flashed .45 NL but since last 2 days it was staying awake even with super light usage. I tried the above solution and now it sleeps well again. weird but works.
[Sony Xperia S, Acro S, Ion] metcard:
Sony really need to pull their finger out and address this battery drain issue.

I was easily getting over 5 hours of screen on time with the previous firmware (over my normal 10 hour day) but now I am struggling to crack 4 hours because the bloody phone is constantly awake and draining battery.

I get about the same amount of battery drain listening to music over Bluetooth than not using the phone at all.

Get your shhht together Sony.

so there is no way to make better battery life on xperia s ? i m just shocked about battery,, its drain like hell,, i got xperia s 3 days ago,,,, :'(

Hey guys, I noticed that my battery charges real slow when the device.is on and normally when it's off, and there was.an increased drain over the past couple if days.

I installed gsam battery and it tells me that something called wpa_supplicant is the issue.. What is that?

Build Prop changes to Battery Capacity MAY help!

Hi guys,

After coming across a post about making amendments to the build.prop when using extended batteries, it got me wondering what values were in the build.prop for my SXS.

The post recommended changing a line in the build.prop to reflect that an extended battery was being used and not the original which meant changing the value for the battery capacity (so for example from 1200mAh to 3600mAh). The value in my SXS build.prop was actually 1500, which would seem to indicate that its being read as a 1500mAh battery, when in fact this phone uses a 1750mAh one.

So after a full charge i made changes to the following line:

ro.semc.batt.capacity=1500

and changed this to

ro.semc.batt.capacity=1750

Then wiped the battery stats and charged phone again for another hour whilst switched off.

And so far, I must admit there is a noticeable difference, with my phone easily lasting a whole day with mid-heavy usage (including 30mins music, 1hr of Asphalt 7, several phone calls and a couple of hours browsing).

Not sure if this is due to the battery calibration or the changes to the build.prop, but whatever it is, it worked!!!

Can any devs shed any light on this??

Give it a try and let me know!

[Sony Xperia S, Acro S, Ion] donjamal:
recently i unplug the phone in the morning from the charger at around 5am, around noon i'm usually at around 50-60% listening 1:30-2 hours to music, a few calls, sync on for most google services, except the ones with havy data usage (like pic sync and stuff), but contacts, calendar, gmail is syncing. wifi on for like 5 minutes, checking xda a few times and facebook as well (totally max 20 minutes). other than these, it's resting on my desk at work. it drains like crazy, it was never this bad. it lasted until i got home around 7pm or sometimes even more with the same usage. yesterday i plugged it and charged it to 70-80% (can't remember exactly, i read 10-15 minutes on the train on the way home on the phone, and at around 8pm it was at 15%. i started the day with 99% when i unplugged it in the morning. no new apps, nothing. all the same ones i used before, and the phone actually goes into deep sleep. something is seriously f#cked up.

Yep, the graph shows it's been charged, one time for at least an hour or so..

Did you plug it into a PC or car stereo or something, or just forget you charged it?
[Sony Xperia S, Acro S, Ion] Sirence:
Only 24 hours? My phone lasts 100 days + with charging now and then :rolleyes:

Joke aside, only the time the phone lasts from fully charged to nearly empty counts as your battery life, without any charging inbetween, not even half an hour if charging.

Nice idle. I had 3% of consumption in 9 hours
[Sony Xperia S, Acro S, Ion] d_ave:
I have noticed, that if i turn off data, wifi and sync the battery life is great. Any ideas? During the night i'm using the sony power saver and i noticed only 2-3% battery loss over 6-7 hours, which is great. I cannot identify any real battery drainers, so it should be something more general, or well hidden in the Android OS. Any suggestions?
[Sony Xperia S, Acro S, Ion] Nepythys:
Personally, I recommend charging your phone while powered on to 100% then shutting down and keep charging, you'll see that it's not really 100%.

Once it goes full, delete battery stats and that should do it. That's how I got 0% drop in 9 hours.
[Sony Xperia S, Acro S, Ion] Sirence:
Connecting to the pc does charge the phone. Every time the green battery graph goes up it was charging at that time.

My Xperia takes around 45 to filly charge, so connecting it 15 mins is like filling up around a third of the battery.

[Sony Xperia S, Acro S, Ion] neizel:
But your mobile signal is very bad, and that forces the antenna and use more battery than android is processes I think because of the continuous search of better signal.
[Sony Xperia S, Acro S, Ion] Felimenta97:
I always had signal like this. Most of my time is home/school.

The awake times Is that I really woke the phone up, to use something, but that is just eating too much battery.

[Sony Xperia S, Acro S, Ion] neizel:
I discovered that AudioEffect.apk awakes the phone a lot of time, try to disable that app. If you use xloud or any headphone effect the process reactivates when you play music, so no problems if you do this.
[Sony Xperia S, Acro S, Ion] Nitorin:
I am having this issue when my cellphone keeps awake most of the time. Even with Juice Defender. Notice that it has been on battery for almost 15 hours but just because the night profile was under effect. When I woke up 10% of the battery was gone when it was supposed to be on idle. And then, some use that includes just listening to some music and check my mails while commuting to the Uni then to my pocket again but still keeps actively using the OS. It's annoying, lately I fixed the Mediaserver issue by being more careful when organizing my music library and to be sure I installed Watchdog to keep an eye at the CPU use (this issue meant that Mediaserver would use 100% of the CPU draining lots of battery and producing lots of heat in the process)

Check how it drained while doing absolutely nothing, not even the screen.

Dunno if there's a way to fix this, my bootloader is blocked so I can't try different ROMs either. Cmon Sony, you did a fine phone but this is so far the worst issue.
[Sony Xperia S, Acro S, Ion] doministry:
So strange. My phone also shows some activity under the screen OFF but than it loses 1% through the night on FlightMode.
[Sony Xperia S, Acro S, Ion] tel033:
Can you explain please why does mediaserver use much battery, I mean when you organize your music in a wring way?
[Sony Xperia S, Acro S, Ion] Nitorin:
Well, turns out that Mediaserver freaks out when you have corrupted files on your SD partition. Also having image files in the same folder as your music seems to have a effect on it too. So I just formatted my SD partition and carefully put all my music in one folder only (Media) as the Music Player will arrange them inside the phone. I would also recommend installing Watchdog so you can tell when Mediaserver is freaking out and undo anything you did before that. Google Music is also related to this issue so I didn't installed it again.
[Sony Xperia S, Acro S, Ion] edmgt:
Sorry, if this sounds stupid, but is there any way to see what apps are draining my battery so bad? Even when i'm not using my phone it goes down pretty fast and i don't recall this issue before. I'm using stock ics rom and the "Awake" in my battery history is almost fully blue. Does that make any difference to my battery life?
[Sony Xperia S, Acro S, Ion] milton.bain:
Use better battery stats app for tracking . To keep your device in deep sleep activate wifi. Idk why..... But thats how it works for most.
[Sony Xperia S, Acro S, Ion] edmgt:
So in order to make my phone's battery last longer i need to keep wifi on all the time?
[Sony Xperia S, Acro S, Ion] Galaxen:
I've noticed that battery life is much better when wifi is on. Simply because it's not jumping from 2g to 3g every damn second due to crappy carrier. If you set your phone to only 2g or only 3g then you'll have more juice left.

Can you brief on what you did to achieve this battery life.What kernel(and from where did you get it) and firmware you have installed it.

I'm on stcok ICS kernel and .50 firmware but lose 3-6% of charge at night with no application running.

Thanks!

Battery Test

Hello everyone!

So, I've been reading on xda for quite some time now and I've finally managed to join ;)

Yesterday I did some testing of my Xperia S battery and I want to share it with you.

My XS runs on stock ICS 6.1.A.2.45.

My first test was screen on for 2 hours. Wi-Fi, mobile data and NFC on. Brightness was set on 50. In those 2 hours battery dropped to 76 percent which is pretty good. According to this I should get 8 hours of screen on time and the battery would drop 96%.

And then I was wondering how much would I get while browsing.

With the same configuration as before I did this test in Dolphin Browser because of Tab Reload plugin, which I set up to reload website every 15 sec. I had desktop mode on and flash also on.

After 2 hours battery dropped to 48%. So I should get almost 4 hours of web browsing. This is not that much so I really hope that they will enhance battery life in JB. The sooner the better.

And I really hope that they will solve the problem with Android System always waking up the phone. This one is really annoying. Some times it's better some times worse but nevertheless annoying.

I will probably do some testing with screen set on 15%, which is good at night. And I will also try in default browser to see the difference. When I'm done with tests I'll post the results here ;)
[Sony Xperia S, Acro S, Ion] jakoh:
so really can i expect this phone to go one day syncing twitter and mail and some web browsing?

troll alert: All apps pretty much, the reason i dont have an android, iphone or windows phone.

your location is the bounty for the apps on these platforms, to use and sell as they please.
[Sony Xperia S, Acro S, Ion] PLovrin:
Personally I have wi-fi always on at home (even at night) and mobile network when I'm out and mail is syncing non-stop. And I also don't have any battery savers. My usage varies from day to day but it always gets me trough that day. For usage like this with some web browsing and taking pictures, recording videos, watching videos and some apps, google play etc. it gives me no problem. Problem for battery is hard core browsing. When I did this test it got a bit hot too. But who is even browsing like this, with 15 sec reload? It is really an extreme test. I will try regular browsing for 2 hours tomorrow in stock browser and I'll post the results ;) And as we have seen with SGS3 web browsing ICS vs. JB had really big difference (1 hour). So let's hope the same will happen with XS.

[Sony Xperia S, Acro S, Ion] jakoh:
why does it stay awake?
[Sony Xperia S, Acro S, Ion] metcard:
The constant wakes by android system are bloody annoying.

The worst part is that I actually managed to fix it with the previous firmware by keeping WiFi on, but with my current firmware(.45) it just doesn't sleep. I lose about 15% of my battery in standby over the course of my 10 hour day.

I'm hoping that when I finally get the .50 firmware that Sony have fixed the issue... unlikely

One thing is for sure, if Sony keep putting these puny batteries which can't be replaced by the user and which take forever to charge, my next phone will not be a Sony. the razr maxx is looking mighty tempting.
[Sony Xperia S, Acro S, Ion] PLovrin:
Have you guys tried restarting the phone after charging? Some times it's better for me after restart. As you can see, right now Android System has been using 23% of battery. Some times it can use 50% of battery or more... And when I see that I charge the phone to 100% and restart. It usually helps. Try if it helps you too ;)
[Sony Xperia S, Acro S, Ion] neizel:
But now shows only 23%because of the screen usage, which is higher than the android system. You have a lot of awakes
[Sony Xperia S, Acro S, Ion] PLovrin:
Yes of course but still not that many as some times. Some times it's like utsav911 showed in his screenshot.

If you look now at my usage you can see that there aren't many awake times in last hours. While some days it is awake almost all the time.
[Sony Xperia S, Acro S, Ion] utsav911:
I don't understand Why the S does not have the extended standby mode?

It's there on P and sola. I don't know about U. But i guess it would also be having.

So a very big question to me is what is the Xperia S exclusive feature?

The hardware itself is better than the sola,u,p. The screen is better, the camera to is better, it was chosen for the aosp project... I think there are a lot of features that make the xperia s better than those phones.

[Sony Xperia S, Acro S, Ion] kathir.:
I tried doing the exercise that you've mentioned but when I try charging the phone while it is off, it still shows that the battery is full and hence doesn't get charged anymore.

Another thing I noticed is that ,when I unplug the charger after full charge the phone charge hardly stays for a minute in 100%.It was not the case with earlier firmwares.Currently I'm on FW .50 and stock kernel.I unplug the charger at least 30 minutes after it shows 100%.Should I unplug it immediately after it shows 100%

Edit: Also can someone suggest the best custom rom/kernel for better battery life for an average user.

[Sony Xperia S, Acro S, Ion] PhilAd:
There are too many factors which affect the battery performance ... beginning by installed apps (most apps are really crap concerning battery) and ending with carrier and used technology / signal strength / frequency / etc.

I don't have to charge my Xperia S more than my other Smartphones. Using Internet Connection / Facebook / WhatsApp / EMail / Spotify / some gaming / etc. its mostly around 14hours on a working day with a lot of wake ups. Its not more and not less than before. It was worse at the beginning, but since second and third FW it was getting better and better.

I can't tell that battery performance is significant worse compared to others. The specification are more realistic. Galaxy SIII has a good battery performance as long as you do not use the phone and keep in mind that the display of the s3 is really dark and only has weak backlight. Playing Asphalt 7 against a friend my xperia s was lasting longer than the sgs3.

btw. the galaxy s2 got a really crappy battery performance with 4.0.3 ... with 4.0.4 it was getting better, but now its laggy ...
[Sony Xperia S, Acro S, Ion] Sirence:
The battery of the s itself is not better or worse than any other smartphone. I can get 3 days on slight use or only 5 hours if I play games. My phone has the awake bug but it doesn't really drain any battery.

I'll stop worrying about battery life in my s. It's more than enough.

View attachment 1407699

About 30-40 min of Asphalt 7 gaming (a little less than the entire 7th championship), 20 min of music, two shut downs and followed by boot again. A few dozen pictures, lots of wake ups for the false hour seeing (yeah, even watching a wrist watch), a lot of time with WiFi (I think for 5 hours, maybe a little more,, maybe a little less). Two or three small calls. Some use of calculator.

I've been testing MX Player battery usage, and something seems very odd:

- max. brightness, ~28 min video, took ~8% of the battery

- brightness of 7 or 10 (out of 15 possible with MX player) for the same video took ~7%!

- turning the screen off during the video playback, same video, also took 7-8% of the battery

- max. brightness, same video, S/W decoder this time, 6-7%

I cannot explain how video playback with the screen off uses the same amount of battery as with screen on! We are talking of a considerable % of battery and time of playback, so it is not something within margin of error.
