my xperia sola battery lasts for only 18hrs with minimum or no use.i have noticed in battery usage info that android os drains around 30-50% battery.and after doing some research on xda i came to know that this is a software issue which was also present in xperia s.is there going to be a firmware update for the xperia sola to reslove this issue?.

Try following and you must be very happy with batter performance:

1: Update your phone software via Sony PC companion. (It’s very easy)

2: Use Power saver mode of the phone if not using phones all the features.

Trust me I have experienced extensive improvement in battery performance. Most likely it was a software bug which has been fixed by Sony.

Good luck!!!

My sola Battery also only lasts for one day, sometimes one day and a half.

I have Bravia engine turned off, floating touch turned off, 3g turned off, screen brightness set to the lowest setting and power saver turned on.

What else can I do???

just find out what is draining your battery, charge your phone 100% then use it normally, don't charge it, once you get to 10% go to

settings -> about phone -> battery use

take screenshots of the item list and the graph, then write down how many hours/minutes/seconds each item on the list was open/on/etc and post all this here

Today my sola was turned off when I woke up.

Plugged it to my computer and he started charging.

When to see the battery settings and it only lasted for 18h the battery usage was the following:

26% screen - 32m 6s

23% standby - 18h 21m 42m

23% android os - 38m 55s

15% phone idle - 17h 49m 34s

12% vouce call - 8m 43s

2% android system - 4m 1s

I only had two or three call lasting 5 minutes tops.

I used wifi to download a nfc app and played with nfc for about 30 minutes.

If this phone's battery is this poor I will return it to the supplier and ask for a refund.

I love Sony's products (I own a sony TV, a ps3, a psp, a couple of headphones ) but this one is not as good as the other one's I have.

Sony are you decreasing your quality?

Try to change your "floating touch" wallpaper or live wallpaper into ordinary ones and turn on the power saver. See if there's a difference. It works for me and now my battery lasts for 2 to 3 days.

I agree, the Live Wallpaper is a power hungry "app". Use a classic wallpaper.

I did some research and found out the linux suspend thread is using all the cpu, using all the cpu thus using all the battery.

There seem to be numerous issues on the internet but none provide a decent anwser. Following whole thread to increase battery life is not an option, it is a kernel bug and should be fixed. I'm looking to the sony service center for this one. How can I contact them?

I guess a software update will fix this bug.

I noticed strange thing - when my Sola is fully charged, battery voltage is 4202mV =>100%, and fully discharged at 3212mV => 0%. Thing is that at 50% battery voltage is 3775mV, 40%=3760mV, 30%=3740%, 20%=3710mV and 10%=3600mV.

And phone is automatically turned off only at 3212mV.

So, my question/theory is that eater my phone is miscalibrated, or Sony won’t me to start charging my phone at 40% of real capacity - to prolong battery life...

Have you tried a Repair with PC Companion and a factory reset ? I'm thinking that If it is a bug, it should appear on all the units using the same hardware revision and software , and a clean install of the OS should fix the glich because the majority of users don't have this problem.

In your case i'm thinking that there are 3 options :

1) battery problem ( bad manufacturing process )

2) OS bug

3) An app that's keeping your OS busy and it's not showing in the battery usage app.

There seems to be a battery drain bug in the Xperia Sola caused by WIFI. A Dutch website discovered this. I also have a Sola and if you switch off WIFI (only turn in on when you use it) it makes a difference. I get quite good battery life with mine!

I suppose the bug will be fixed soon.

Addition: Things like Bluetooth, GPS, Floating touch, BRAVIA engine etc really don't matter, since they only use power when they are actually used. I have them all on all the time. Of course when you really never use things like BT you might as well turn them off, but otherwise, don't bother.

"" If you still see a too huge drain on the battery, then try to remove the microSDHC-card overnight, to see if this is where power goes.""

Ah, now that's an intersting idea. The SD would be one of the "differance" I have.

Re: poor battery life on xperia sola

EowynCarter1 — Fri, 29 Jun 2012 07:10:13 GMT

SD removed, no more battery drain.

That's a start. Now i need some more test.

Are you kidding me ? SD card drains too much battery over night ?
