Hi everyone. I've bought my new xperia arc s on Wednesday and unfortunately I'm very disappointed with the battery performance. It is worse than my 3 years old iPhone. I've read many advices in the internet concerning this issue, but none of them gave any improvement for me. I want to emphasize, that I switched off: wifi, auto-sync, GPS & wifi localization etc. My display is at 30% of brightness. The only functions which are turned on are: 3g network and background data.
However, my smartphone needs to be charged after around 10 hours of not very heavy using (web browsing, ca. 20 minutes playing games such as angry birds or cut the ropę and 20 minutes of listening music player.
Today's performance was just tragic: 5 hours of working (less than 3.5 hours of the turned on screen; only 3g connection on). What should I do to improve these results or maybe the battery is broken and I should send the phone to the warranty service?
Thanks for help

Of course I'll wait, cause I don't want to miss my phone, which looks and works amazingly great. But do you have any tips which would help me to increase battery performance? All I need is 3g or wifi constantly turned on for google talk and facebook messenger.

I using this for 4 months, still ~6 hours with usage, ~8 hours normal usage, 10~ hours no usage
Using doomkernel v19,stock .62, smartass v2 133~1400, undervolt 100mv
Even without using this kind of setting and kernel i still get same result

Are you kidding me? It cannot be that bad.
My phone isn't arc s it's only arc but my battery lasts over 24 hours.
I run wifi and 3g always, usually there's over 1h of calls some web surfing and stuff. With this kinda usage it normallly last something like 36h. If i don't use phone it's over 48h.
You should check what has been using the battery.

I don't know how it's possible. I have only 3g data transfer turned on, while everything else is turned off. I checked in settings and it is screen which consumes 60%-70% of energy in my case. Is it normal? Moreover, could you tell me what is your maximum time of the screen turned on achieved without loading the battery?

Not kidding. Usually if i dont touch the phone, just the normal stuff that use the battery (display,idle etc.)
I use an app called my battery drain analyzer and it shows even when in idle the battery lose about 7%-8% in an hour.

Ill give u few suggestions
Turn the screen brightness to 30 40 % this will give you 4 5 hours more of stand by
Turn off 3g(data internet) it eats as much battery as the screen,use when u need it 4 6h more on stand by
GPS turn it off lol u dont need it to be turned on all the time,use it just when u need it
Im using this setup for 2 months not and its awesome im on 54% battery and the phone is charged before 21h.. i will have 30 + for sure

Hi, just some suggestions.
1. Do you use latitude?? That puts a huge dent in your battery.
2. Do you travel around during the day?? I find that my battery drops a lot quicker when the phone is forced to switch between towers a lot.
3. Try and check the date of manufacture on your battery, It may be old.
4. Did you properly condition your battery when you first got the phone (Takes about a week to do it right but well worth it in the long run)
5. See if you can borrow some one else's battery for a couple of days and see if it makes a difference?? (Isolation testing its called)
Or you could just have a bad battery, that happens.

I'm not sure how much my screen uses battery. I haven't evaluated screen always on usage.
I'm running currently at 46% 23h 3m 54s
voice calls 38% (1h 5m 20s)
wifi 19% (23h 3m 54s)
cell standby 14% (23h 3m 54s)
phone idle 12% (21h 45m 47s)
display 11% (47m 32s)
after these come other less significant stuff like Android OS, Android System, Web browser etc.
In my use are: DoomKernel v20 undervolted -75mv and Juice Defender.
I have also removed many softwares that are useless for me like support.apk etc.

It must be bad battery. If no apps are draining your batt.

it will identify it down to a specific app or a module in the kernel, where the drain is coming from.

Man, this is a problem that occours in every android phone, even those ones which have a more powerful battery.
I use an Arc S overclocked (but not too much) and the battery lifes varies a lot, depending on which kernel and which rom I use. The best battery life i've find so far was DoomKernel ICS v4 with Arconium ICS v5. But it was a little bit laggy and now I'm using KA13 with the same kernel. The battery life is not bad, but not really good.
Sony knows this issue and I'm sure they're working in order to fix this on the official release of ICS. Just wait

changing kernels usually helps
I am here to share my experience to get 18 (around 5-8 hours screen time depend on your usage) hours normal usage, browsing chatting, facebook and calls.
2 days if you are not touching your phone at all, standby.
follow my guide, I think it's all about the Kernel but I shared the rom I used too just in case.
this guide is for GSM, might work on others just download the proper rom and kernel.
Optional, you can underclock to 1ghz but I didn't and got 18 means more if you underclock it.

point 1: when you go to 1GHz , it's called underclocking. undervolting is when you lower the voltage for the corresponding processor frequencies.
point 2: 18h , but what about screen ON ? how much is the "normal usage" equivalent to, in terms of screen ON and the stuff that you're running on your phone.
it's nice to see you trying to contribute and thumbs up for the effort, and i really don't want to sound like an a-hole, but this is not a guide. flashing a custom rom + kernel, and letting the battery go through a few cycles cannot be considered as a guide with battery saving tips. Cheers mate.

You are right, but I learned now ^^
well around 8 hours normal usage of screen time (screen awake), and when I am on a phone call and the screen is off it toke 1% every 10mins
pardon my English
delete this reply cuz I don't find how.
Yah I hate to be that guy but where's the guide? Everyone uses their phone different. You should at least show your battery usage screen shot so we can see screen time etc.
What? Are you telling me that you get 8hrs of screen on time? Is this trolling or just a language barrier?

sorry, I wiped stats but you can study this.
just look at my charge time compared to the times I am using phone, and because it last longer I don't care when its red and low, I was in 5% from 9pm to 11pm chatting from time to time and facebook, and btw my wifi is always on.
and pardon me I am new Xd I am just sharing something not an expert or something but next time I will make sure : it's called underclocking <- I though both are same, and post screenshot and screen on time
EDIT: I think I should charge it to 100% and make it drain then share pics with you guys, that's the proper way for screenshot right Xd? cuz mine looks like a mess XD

Nice XD but I love messing around my phone stock is just... normal XD
Your phone was plugged in multiple times throughout your screenshots. So yes, you should redo screen shots from 100% and include display on time.
It doesn't really matter though, as no one will see your same results unless they use their phone the exact same way.
And under clocking is unnecessary on the nexus, it doesn't spend hardly any time at 1200mhz anyway. I use mine for a lot of game play and still don't spend much time over 691mhz (Trinity kernel). So if my phone decides it does need to ramp up to 1190mhz to remain buttery smooth I'm not going to interfere.

Same here. I have no problem getting 18 hours out of my stock battery using the stock ROM and kernel, including just shy of 6 hours of screen on time.
I dont know that I would call this a guide. Its saying to use a certain rom and kernel and to charge the phone. . . . .
hey thanks for the write up... i used it alone to change the colors! now my screen isn't yellow.
question though... when I adjust my colors manually, when I go to 0 percent brightness, everything goes like super green... like crazy looking lol.. but at 3 percent it's fine again... any idea why this happens and how I can fix it to get true 0 percent? thanks!

I'm using a stock one and all I can say is: Just dont use Nexus as a videogame.
I got 3 days and some hours of battery talking some minutes and using wifi for some time (probably 4 hours overall).
Playing sucks up the battery life. At least for me.
A normal day of use, with wifi active, many calls, auto bright and SetCPU profiles gives me 'bout 18-24 hours of use.
A intense play day gives me 8 hours. And I think its generous.

Finally I helped one person, thanks man I love you XD
and this guide is just experience, because most people are wondering what is best rom and kernel combination, well this was best for me at least.

I flashed Jellybean for my gnex this last weekend, and I've noticed a severely precipitous drop in battery life (15% in 90 min, 15 min screen on). I found this yesterday when my phone went completely dead after just 6 hours on idle, despite running some pretty severe power-saving options. I can literally see the battery draining as I took the screenshots to post.
Running 4.1.1 stock, Franco Kernel Version 5 (power save powermode), 2100 mAh battery - I tried to provide as much information as I can in the screenshots. The weird thing is that none of the information stands out as an obvious power-drain, its just falling for what I believe to be no good reason.
Please help!
First of all: congrats if providing such detailed information about your battery information! (I'm being serious, not sarcastic)
Secondly, have you tried running it with WiFi only to see if there's a difference? Also, you need to go through about 2-3 charge cycles before you have a good idea of our battery range.
Also, what kernel are you using?

CPU Sleep
Thanks! However, I'm already running on only one core, from a setting in Franco's app.
My problem is that there doesn't seem to be anything glaring that is draining my battery. Awake time is slightly more than I'd like, but not nearly enough to drain the battery at 10% an hour with the screen off.
And for the above poster, I have not tried running it with wifi only and no mobile data - wifi at my office is spotty, and I'd like the conditions I am testing it at to try to mirror how I would normally use my phone.

hmmm... did u try replacing the battery?
Battery
No - the battery worked just fine on ICS as of last Friday (28 hours standby charge). I would hope that flashing ROMs/Kernels would not actually damage it.
Thanks for trying to help - I'm really confused since all the ratios look comparable to people who get great battery life, but for some reason, just seem to suck about 5x more battery for me, so its impossible to pinpoint one specific culprit. I thought it was a mis-calibration, but apparently that is just a myth.

Let me start by saying that I am not an expert, but the following tips helped me. I agree with the WiFi and the detail you provided was great. I see that you are running 4G, this will eat up the battery. Your ROM may have a toggle for the 4G (LTE) and 3G (CDMA). If you have WiFi available I would use that. You may want to turn off the NFC (system setting>Wireless & Networks More....) unless you use google wallet or share screen alot. Also, I had horrible results with the Facebook app running in the background, which I have taken off my phone. I set a bookmark in dolphin browser instead of using the app.
If you are not seeing any improvements with in the next few battery cycles you may try wiping the battery stats in Recovery. The first ROM I flashed from stock my battery life was all over the map and wiping battery stats helped. I ran the same Franco Kernel and was getting 2.5 -3 hrs of screen time. Hope this helps.
also, get CpuSpy from the market, and see which speeds your cpu is using (or not using).
Not that this will help software issues but Sprint is giving away a free 2100Mah extended battery with the door. You just have to pay for the shipping. No scam at all, I think they know that they have a glitchy piece of product and need to help calm us down. Just call telesales and tell them you own a Gnex.
CPU Speeds
Almost exclusively at 384 or 729 mHz, capped at 1026.

So that means that the CPU isn't going into deep sleep, which is an issue.
All I can suggest is reflash with a full wipe, and reinstall the apps you can, and slowly weed out any rogue apps that could be causing said issue.

Deep Sleep
Sorry, I meant that when awake, the vast majority of the clock speeds are 384 and 729. I am in deep sleep approximately 75% of the time.
If no solution comes up in this thread, I will try re-flashing to stock JB/stock JB kernel tomorrow night to see if it just needed a few recharge cycles to stabilize, and if not, if wiping/reinstalling helps.

Yeah, that seems to be the general experience here. My phone is down to ~28% since the OP. Again, the proportions in which things are draining power are correct, they are just doing it too quickly (1% per minute of screen time).
I'm going to completely wipe and re-flash JB tonight, keeping the stock kernel this time, unless someone can help me out.

Did u flash francos kernel yet ?
Sent from my Galaxy Nexus using xda premium
Yes - every process/screen is drawing the typical percentage of power use (~50% screen, 8% Phone Idle, 8% cell standby), but the battery is draining 4x faster than it should. Francos app shows me running at completely standard voltage, and I'm on the powersave mode. I think it must be a battery indicator/stats issue, otherwise the proportions would be all off.

Excellent! with heavy use of ~ 200 emails a day 1h on internet and about 30min looking up news and 1-2h of calls i get 12-16h.

Battery is ridiculous. After diagnosing my wifi wakelock issue and installing jedi rom I get 4 hoursish per 1% when it goes into sleep, and that's in a basement mostly with horrible reception.
im getting worse battery life ever since the multiwindow update. not sure if anyone else has the same issue, but it seems like tmobile users are complaining about the same thing. it might be due to lack of battery calibration.
Well, here's a visual. Just achieved this impressive feat. 81 HOURS on pure battery! Almost 3.5 hours of screen-on time. I choose to not utilize my phone much over the holiday weekend, so that explains the low screen-on time. Regardless, I think these results are more than impressive. Nothing was restricted on my device. Live wallpaper going the whole time, auto screen brightness (usually a high setting), WiFi going, auto-syncing from emails to Facebook to Twitter, watched a bit of "The Dark Knight Rises" in full-1080p HD, made a bunch of miscellaneous phone calls. I am more than amazed at this phone and its battery. Haven't seen anything close to this in more than five years or so. These results are after updating to 4.1.2 with multi-window, and these are the best results I've ever gotten on this device.
On a side note, if anyone is getting results like the first poster with 8+ hours of screen-on time, it would really help if you described what you typically do with your phone and what you may have done to your phone. Just posting a screenshot tells nothing. You could be web browsing all day with your screen set to 20% brightness, and nothing more. What are you doing? Watching movies? Listening to music? Emailing? Texting? And if you're rooted that makes a ton of difference, so the results wouldn't be exactly truthful or accurate I should say.

Well, here's a visual. Just achieved this impressive feat. 81 HOURS on pure battery! Almost 3.5 hours of screen-on time. I choose to not utilize my phone much over the holiday weekend, so that explains the low screen-on time. Regardless, I think these results are more than impressive. Nothing was restricted on my device. Live wallpaper going the whole time, auto screen brightness (usually a high setting), WiFi going, auto-syncing from emails to Facebook to Twitter, watched a bit of "The Dark Knight Rises" in full-1080p HD, made a bunch of miscellaneous phone calls.

Sorry for the lack of detail, I should have included that. I was browsing the net on wifi, playing Words, emailing/texting, various phone calls, watching youtube videos, and spending time on the XDA app. (of course)
I'm rooted and using clean rom 3.5. Auto brightness is on and I'm about 50% on the slider.
Here is where I sit today: (not much youtube though)

^^^ Thanks. So, that does change things, since you're rooted. The reason why I'm making a big deal about it, is because your results (and anyone else rooted) aren't typical results of someone stock. So a person not knowing any better would assuming they'd get your battery results from stock.
How is that possible? I use my note for about 5hrs of screen time and it's at like 3%. I am on an international rom and I undervolted along with perseus 1.8ghz kernel. Even when I did not have perse us, I never got above 6hrs? What settings do you use? I'm on wifi all day with the brightness All the way down. Please let me know! I really want to get that 8hrs of screen on time!

Clean Rom 3.5, I also make sure and close out of anything I'm not using. I also use the ES Task Manager widget to clear my ram before I power down for any period of time.
That's about it, besides not having a ton of widgets running.
I didn't get much over six hours of screen time with my Jedi Rom, but in fairness to it, it was my first rom and I don't think I did it quite right, installing other things with it that probably weren't compatible.

Like Dr. Evo points out, one of the great things about custom roms is they get rid of all the bloatware from ATT and other carriers. Stock I was lucky to have 1gb of free ram at any time, now I'm always around 1.1-1.2gb free without much effort on my part.

I have installed wicked v3 and the faux m version kernel. The first day it seemed like my battery life was much better. However now the battery life is actually worse. I am only getting 5 or 6 hours with medium use before my phone is almost completely dead and I have to recharge it. I also have it underclocked in set cpu. Can anyone suggest what I could have done wrong?
Thanks

install wakelock detector (free) or/and betterbatterystats (paid.. like 2 bucks). It might not even be a problem with the rom/kernel, but more with wakelocks causing your cpu to run while the screen is off. if the wakelocks are out of control, you'll see battery life disappear fast even if you put down the phone for a few hours. using the aforementioned two programs you can diagnose whats keeping your phone awake, then google the name of the wakelock (or go to the betterbatterystats thread in one of the forums here), and decide to freeze, delete, greenify or do whatever to fix the problem.
keep in mind that betterbatterystats will detect more kinds of wakelocks, but will not be very friendly to people who can't understand whats what. wakelock detector will detect most wakelocks, is very clean, but the one wakelock it doesnt detect may be burning your cpu.
if you want to extend your battery life a bit further, you can use tasker to turn off certain things that use battery like: 4g, wifi, gps, and turn them on when you: need them, have the screen on, open a certain application, at a certain time, etc.

5-6 hours of screen time??
Sent from my SGH-M919 using xda app-developers app
Thank you for responding. I have installed wakelock and will see what the results show later today. If I upload a screen shot of the results on here would you help me review them? I fall into that category of user who probably will not know what's what as I am just diving into the world of kernels. Also I am only getting about 5-6 hours total time, not screen time. I've seen others say they are getting 10-15 hours or more with faux kernel. For now I have actually switched over to ktooneez kernel due to the poor battery life I was getting from faux kernel. It seems a little better so far but still not near what I was expecting from others comments.
Thanks.

then it probably isnt a problem with your kernel
