Sony Xperia S LT26i Battery Life Issues

catsmaty — Sun, 20 Jan 2013 12:49:44 GMT

Hi,

After the latest update my battery keeps getting drained very quickly, I have to charge it twice a day sometimes, when I checked the Battery use I found the android system used 59% of the bettery, it is always the same percentage whereas my wife's phone is on Andoid V2.3 and it last 4 times the life of my phone, could you please release a patch to fix this problem?

I wish I could roll back the update.

I am having the same issue....battery is draining rapidly....and the phone keeps on waking up inspite of being on standby mode....dont know how & why...the only saving grace is by keeping the data connection off i am able to save some juice.

Well, it's always hard to determinate if these battery issues are due to faulty phone or intense usage. Check this thread for some tips:

Hi, Samuel.

Thanks for the reply.

However, in the link you provided it is recommended as a last resort to take out the battery, which is not applicable for the Xperia S device.

I recommend installing the GreenPower Free software for increasing the battery's performance.

I use it myself and the battery's performance increased after I started using it.

For the millionth time the Android system is so high in the usage stats because nothing else is using it. If nothing showed up in the usage stats the battery would last for ever and ever amen.

Turn mobile data off and WiFi off when not in use as these along with the screen munch the most power.

Look how high mine is.

I would be interested to have some support in investigation actually what application keeps the Android system awake in most of the time, for me the Android system is keeping awake the handset in 30-70% of the time. Now I'm using the latest .55 fw but no change in this behaviour. I would bet, that we could double the stnby time if this would be fixed. THNX

I face this problem in xperia SL as well.It looks more or less like software glitch for me based on my experience.I had the same problem when i purchased the phone a couple of months back and after a Sony service centre updated the software(although I had 6.1.A.2.45, which remained the same even after update and PC companion showing phone up to date),phone battery life improved tremendously..With no Wi-Fi,games, etc and only with 8-10 calls a day, battery life extended to almost 3-4 full days.Then one day, PC companion told me a new version of software is available, although there was no mention of what the software is and what version it is.I upgraded it, and battery life was back to square one again..Now,before updating, i took a backup using the backup&restore option in the phone itself and i did a restore from that after a day, and battery life, strangely came back to the same 3-4 days again. Couple of days back PC companion told me about availability of 6.1.A.2.55 (here in India) and pushing my luck a bit, i updated to 6.1.A.2.55 and I am back to square one again..Battery compleletly drains out in 8-10 hrs even if phone is not used at all.Without using Wi-Fi,Games, movies,music etc..This time, even the backup&restore option did not help..So it is pretty much evident that some bug in the software or firmware is causing this huge variation in battery life.Hope Sony checks this and provide some relief to customers as it is pretty hard to charge the battery every 8-10 hrs.No hope though as they are curiously silent on this issue and just provides some standard tips which does not help at all.

And i'm betting it would make very little difference, over night when my phone hits deep sleep the battery lasts between 2 and 3 hours per 1% drop in battery life, the behaviour was the same on the .453 and .45 ICS firmwares, this gives a potential standby of over 8 days and i'm guessing it would show the Android usage at nearly 100% if this was indeed possible.

Hi,

I use some tips to maximise the battery life on my Xperia SL. During the night, i always use Timed Power Saver and my battery only drops 4-5% during 7-8 hours. I check which apps drain my battery and i disable them or remove from my phone the ones i do not like. Also the Screen is a battery killer, try to use not more than 30% brightness.

If Android is consuming the most of the battery, restart your phone. It will free up the system resources.

Cheers

Unfortunately, my problem is related to Android System consumption. During one day, the AS consumes similar power to 1 hour screen usage, keeping awake the handset 30-70% of the "on" time. But no clue which aplication or task is the quilty about this...I've an Xperia J, and the battery time of that is significantly better than for the S. and the awake time is also less for Android System.

Hi.

I checked regarding the Android System consumption as well and I found the following:

The Android System is definitely consuming more than it should.

By clicking the Android system entry above it shows the following:

In the screen above I noticed the following:

The Keep awake value is very (6h 38m 40s out of 16h 26m 5s).
There are two Sony processes (com.sonyericsson.illumination.service, com.sonyericsson.newsoftwarechecker) which are part of the Android System (???)

Could someone from Sony, please, clarify this?

http://battery.rootuninstaller.com/app?pkg=com.sonyericsson.illumination.service

above is a report about the battery consumption of the illumination service on some devices, on ION is quite huge...

Re: Sony Xperia S LT26i Battery Life Issues

ymagriso — Thu, 24 Jan 2013 16:36:32 GMT

Thanks for the information.

Is there a way to disable (or reconfigure) the illumination service?

Please, advise.

I think no way to disable without root.

Now I've tried a batsave app, and works fine, similar to Enhanced Standby mode (sxp). It is called Greenpower.

Im not sure what you are expecting but over 16 hours standby given your usage is more than respectable, you are not going to pull a magic rabbit out of a hat and suddenly get 3 days standby with use. The XS has a fairly weedy battery with a high resolution screen and a not the most power efficent processor.

I completely disagree with you MrBelter.

What you see above is something which is seen on a good day.

The phone rarely lasts for 16 hours (I don't usually let it get to 3% and charge it whenever possible).

Furthermore, the phone requires a restart at least once a day because after some point the battery drain is increased (and according to the above and to other posts in this forum) because of the Android System is misusing the battery.

So, in other words there seems to be issue with the Android System on the Xperia S device (specifically for ICS 4.0.4) which affects the battery's performance.

For example, the phone has been idle for 2 hours (and was charged after for ~30 minutes during the time a GPS software was on) and still the Android System used most of the time instead of the Phone idle:

Am I missing something?

I bought sony xperia sl 3 days back, and it's battery behaving weird since 1st day. The moment I onnected it using PC companion, it recommended me to upgrade from .45 to .55. Now, the battery

level varies 70% to 2% in 5 minutes, and even after charging for more than an hour, phone doesn't start sometimes. It's charging- discharging varies like anything and also creates the problem like - phone hanging, screen freezing and phone switching off automatically. I am not sure if there is problem with battery, or any software issue...Can anyone help?

Took my phone to an xperia service centre today..After connecting the phone, technician told me a new software update is available, and was told to leave the phone with him for update..Could not do it as i dont have another phone..When checked through PC Companion or Update Services in my laptop, both tell that the phone is upto date..Does this mean Sony Service Centres has access to a different software version which is not provided to customers publicly ? if someone from Sony reads this support forum, could you provide an insight into this ? Or did the technician

lied to me ?? Curious to know...

Current software info attached for ref..cud anyone tell me this is the latest one available with Sony as i am tired of researching this battery issue..Curse the moment I chose to upgrade software&firmware as everything was alright prior to that

I just updated to JB 4.1.2 Build 6.2.B.0.200 yesterday through PC companion. Before update, my Xperia S works well and battery can last about a day, but sadly after update, my battery now suddenly drain so fast and will go flat in less than 2 hours after charged.?????

Why this thing happen? Suppose new update will give you better performance. But what happened is the other way around. Please help.

Can I revert back to the old version?
