Battery life.

At least the Xperia S battery doesn't seem to be as bad as the HTC One X. One reviewer has said he needed to charge it twice in one day and it was still running low at the end of the day.
 
I've been using the lock to 3G trick, battery Seems better.
Yesterday it had 2 hours screen on time, put it on charge at 11pm last night, it had 43% left.

That's from being on since 8am.
 
I listened to close to 7 hours of podcasts/music yesterday and heavy browsing before bed for about an hour and was down to about 20%, during the day in the office I have no 3g signal and turn off data transfer and wifi and lock to gsm, as soon as it hit 4 I turned on wifi, data transfer and 3g.
Shame about my screen issue which i'm swapping on Saturday

To back up what Jon is saying I remember (And Jon will know him well) Simon when he was with Motorola gave us this information regarding Lithium Ion Batteries

Tips for making Li-Ion batteries last longer:

Unlike nickel based rechargeable batteries (NiCd and NiMH), Li-Ion batteries should be charged after each use and very often. Never allow them to discharge completely before recharging. However, if they are not used for a longer time, they should be brought to a charge level of around 40%.
Li-Ion batteries should be kept cool. Ideally they are stored in a fridge. However, they should not freeze. At higher temperatures they age quicker. Storing them in a hot car or subjecting them to high temperatures even for short periods can kill them immediately. (Bad news for hot laptop owners.)
Buy Li-Ion batteries only when they are needed. Don't buy a spare battery for future use when you purchase a new notebook, phone, or camera for example. Always look at the manufacturing date. If they don't provide one don't buy it! This is because Li-Ion battery's life cycles are almost completely dependent upon its age from the time of manufacture, regardless if it has been charged or not. In fact, Li-Ion batteries irreversibly lose at least approximately 20% of their capacity per year from the time they are manufactured. This figure is dependent on its stored temperature; 6% at 0 degrees centigrade, 20% at 25 degrees centigrade, 35% at 40 degrees centigrade. When stored at 40% charge level, these figures are reduced to 2%, 4%, 15% at 0, 25 and 40 degrees centigrade respectively.
When using a notebook computer running from AC power over extended periods, it is advisable to remove the battery and store it in a cool place.
Every (deep) discharge cycle decreases their capacity. The degradation is sloped in such a way that 100 cycles leave the battery with about 75% to 85% of the original. When used in notebook computers or cellular phones, this rate of deterioration means that even in short as one year the battery could have capacities that are too low to be still usable.

Morning everyone, from my dabbles in another forum I came across this lot of info:

The problem is related to the phone switching between 2G and 3G too many times in idle mode, that's why a lot of people (myself included) are reporting that selecting either 2G or 3G (rather than automatic dual mode) fixes the problem. As mentioned by another member in this thread, it's possibly related to the com.sonyericsson.android.wakeup process, either way, it's a software bug and nothing to do with physical aspects of the phone.

To those who are having the battery issue, select either GSM or WCDMA instead of putting it in dual mode; this will increase the battery life by a huge amount. This is a temporary fix until Sony fix the 2G/3G switching BUG. To do this go to: Settings --> Wireless & Networks --> Mobile Networks --> Network Mode. And select WCDMA (or GSM if you're happy with 2G)

Before my phone was draining 50% in 24 hours with no use at all; everything disabled, blank screen etc. Now in idle mode, after selecting WCDMA (3G), only 8% drained after 24 hours and the battery was still at 92%. That's a drastic improvement.

I've inadvertently been doing this while at work so have found my battery life to be pretty good, just go test this out for yourself and if there is improvement then you can bet that it will be resolved in some software update either officially or unofficially

There are a whole load of other what-ifs like O2 and something to do with fast dormancy feature, picasa auto updates and there seems to be a working solution for rooted Xperia's too.

Thanks for digging this up Jase. Have no idea what effect it's gonna have on my handset cos I've only just tried it, but hopefully it works as well as everyone else is saying.
 
Well at the minute I'm on 88% remaining, with 11h 26m gone. Although I've barely used it today and it was on airplane mode for about 4 hours over my partners house as signal is terrible up hers.

Discounting that, I reckon I should be on for at least 2 days solid.
 
I average a 12 hour day recently and when I put my phone on charge at around 11pm I'm usually between 40 to 50% left.
That's with the locked to hspda.

Averages 2 hours mark of screen on time.
 
Hi Guys i'm new. Also new to Android and smartphones! Got the Xperia S, think it is awesome,

However I don't think the battery life is doing too well..

I saw someones screenshot on this thread with the display not taking a high % at all, mine is 85% at the moment.

Bravia engine is off, backlight is off, brightness is less than a quarter across the slider..

I'm not sure if 85% is bad, or does it just mean thats how much it is using compared to the other things running at the time? Which is pretty much nothing.

Cheers guys and hi!
David
 
I just thought I'd drag up this thread, I was wondering how you guys are finding your battery life now that we are a few firmwares in.

Also are you still locking your network to gsm or wcdma only ?
And how do you use your wifi and data, do you switch these on and off when needed or leave them on or do you use a battery saving app like juice defender ?
 
Hey, my battery is pretty decent, though I do use Setcpu and mobile net + wifi is only on when I need it.

Tasker is set to turn my internet on when the screen is on and off when the screen is off.

I can take it off charge in the morning and put it back on at 11pm or so with usually around 40% left.

Obviously that varies depending how much I've actually used the phone.
 
Sounds like your using tasker much the same as I'm using juice defender plus, wifi and data off when screen off, I have no frills cpu, how have you set up setcpu?
 
Does anyone know of an external battery for the Xperia S that I can charger up at home and then use out and about? I've just been camping for the weekend and even without using too many apps, I didn't have enough battery for the weekend. The AA emergency battery charger that I bought was not as useful as I'd hoped :(
 
There's a charger called 'pepple' its just a battery that you plug your phone into and it will charge it, I used to use it with my Desire.

how much MaH is the 'pepple' battery?

I also just tested battery life from 100% to 15%

In that time i took 273 photos about 20 photos with flash (took them all in 4 separate times, eg 50 in 1 go and anoher 50 here and another 50 there), 20 minutes of full HD recording (no flash), 32 minutes of voice calls and 30 minutes of music playing. screen was on for 5 hours 56 minutes out of the total time of 8 hours 21 minutes. that is not bad at all, of course no one will take 270+ photos and 20+ minutes of video and leave screen on for 5 hours out of 8 hours. lasted 8 hours doing all of that. screen brightness is set to low
