Xperia Arc S - fast discharging of battery after update to ICS

Wed, 25 Apr 2012 20:19:11 GMT

Hello,

two days ago I updated my Xperia Arc S to Android 4.0.3 and since that time battery life is extremly reduced (i.e. 8 hours). Until that update I had Android 2.3.4 and battery life in the same conditions was 24-36 hours. I checked battery usage and found out that against old version of Android there was new item called "OS Android" which had pretty high consumption of the battery. At the same time there is also item called "System Android". As far as I remember this second item was even in the Android 2.3.4, but it has very low consumption. What is the difference between both items and why the first one takes so much of energy even in idle mode (i.e. during the night)? I'm very disappointed by the update to ICS. Does anybody reported this issue already? Do you have any solution for this?

Thank you very much in advance.

if you have your data plan on or wifi/bluetooth on it will drain your battery a lot faster, 12hrs is more or less normal with a smartphone, so if you had 24+ hours thats impressive and a bit unreal go to settings -> about phone -> battery use and take screenshots

but first charge it 100% let it drain to 10% and post your results here, do not charge it in between and make sure to also include the graph

Hi, thanks for such a quick response. I didn't use Bluetooth and Wifi at all. I let my cell switched on even during the night and with old version of Android it remained charged 24 hours without problem. Of course during the night it was only in standby mode. During the night it took usually about 10-15 percents of battery. But now I had about 40 percents in the evening and in the morning the cell was switched off and completely discharged. My only question now is, how to make screenshot in the ICS, because I didn't find this function (comparing to Android 2.3.4).

Thanks once more.

Finally back with results. My cell was charged fully yesterday morning. Below you can see screenshot. As you can see from the picture, during the morning it was discharging again very fast. The same way it was discharging during two previous days. But then suddenly something happened and it became better. And I should say, the cell was used for the whole period of time the same way. So, finally it took about 26 hours until I got to 10% of battery charge. Before, it was only 8 hours.I will also attach second screenshot with detailed graph. To me it seems like two or three days after update to ICS the cell had very high consumption of energy and then it suddenly became better. I have no idea why, because the cell was used the same way whole the time. Pls let me know about your comments.

wow that's rather impressive, but it makes sense now your battery last so long (24+ hrs) since you are using 2G, go to settings -> wireless & networks -> mobile networks -> select GSM that should save you some battery.

Hi,

I was suffering with same battery drain problem till yesterday but now I have got a solution to make phone faster after ICS update.

NOTE : keep backup of contacts, messages as this will format your phone.

1) After installing ICS once.

2) connect phone to PC via pc companion.

3) Click Support zone.

4) Now click start button on Phone software update. click on repair link.

5) follow steps mentioned on screen and click next, next, next ... till your phone get updated with new software.

NOTE : keep backup of contacts, messages as this will format your phone.

I did same steps yesterday and now feeling much better with ICS. battery backup has lot more improved.

REASON : since sony has just updated your old OS with new OS. This was making some uncompatible changes which slowed down performance and sucked the battery.

You will feel much much better after following these steps..

Let me know if this helps you..

Does this mean that if I use 3G network (even in case of strong signal) the consumption of battery is much higher than with 2G? But still I don't understand why the consumption of battery was so high from the beginning. I used 2G whole the time after ICS installation.

Hi, Thank you for your comment. I will surely try it asap. But, what kind of update is this? Is this new version of ICS or is it some different way of updating phone software?

Hi Wood,

This will not install any new version.

This will just fully format your phone & will place android 4 OS files as fresh install.

Dont forget to backup you all valuable info to sd card before starting this.

It really worked for me !!

yes it will drain your battery faster, specially if you have a data plan.

what ascentway did was to repair his phone, maybe something went wrong with his update and that fixed his issue.

I am also using 3G data active all the time.

Gmail, Email, gtalk and other messangers in sync all the time.

& now getting backup > 1 day with ics. yesterday it was only 8 hrs.

So if you are also getting 8 hrs backup then you should try these steps..

Regards.

Thank you both for your posts. I think, I will try what Anubhav said. But now I'm a bit scared about my datas After this update the phone should face like new, right? If I have all my contacts and calendar synchronized with gmail, will it be automatically re-newed after setting of my gmail account then? What about applications?

Re: Xperia Arc S - fast discharging of battery after update to ICS

Fri, 27 Apr 2012 15:19:07 GMT

Yes, phone will look like a new one.

to backup all contacts >

goto contacts > option > backup contacts > select all > backup

this will save all contacts in micro sd card. which can be used to restore.

Apps will get lost & you need to reinstall them again.

after gmail account setup your calendar will get updated itself.
