[Q] incredibly fast battery drain on xperia arc s.

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

Wait a week, it improves

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

You scared me. I hope it'll get better. Guys, please write some tips to extend battery life. I know that my performance is not normal and I'm 99% certain, that it is a software issue. What am I doing wrong?

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.

read this thread get the betterbattery stats and check it
http://forum.xda-developers.com/showthread.php?t=1433309
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

just do some comparison,differ country 3G line will affect the BL too, just want know which one better.i didnt complaint my battery is bad. when u see a lot of forum member post about this , that means the battery life is one of concern of people.
so i started a thread to gather all the info from member , maybe we find someway to work out for longer the bl of our devices

It looks like you dont know anything about how 3G works and why it may affect BL. Its all about range, protocol switching, and BTS placement.
Keep in mind, this is SMARTPHONE with QUAD+1 CORES and HD display. The good battery life score with average usage is 1 DAY. with heavy usage is couple of H. If you want it to work a week without charge, get nokia E51.
Poeple need to understand that there is no such topic as bad battery life in such monsutros smartphone. Live with it or leave it.

Well I fully charged my HOX on about 20:00 and in the morning when I wake up (12:00- I'm a heavy sleeper ) , It still shows 100% of battery! That's quite outstanding, isn't it?

Yeah after a few days struggling with a battery draining issue I managed to solve it and now my HOX has an amazing battery life Even though it is still facing some battery draining with the camera (Not to mention the scratched camera lens). It lasts 2-3 days with normal gaming. 5-6 days of normal usage (without gaming)

Well I updated the software build to the latest. Than I do a factory reset. After that, I use my phone normally until it shows me the warning of "the battery is lowerthab 10%", I turn off my phone completely then charge it for 8 -> 12 hours then turn it on and use it normally again. Repeat those steps 3-4 times and your HOX's battery life should be fine

My guide for 18 hours battery life on Jelly Bean

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.

Nice. Will check this out.. I run my phone down pretty quick these days heh

I'm not understanding why you prefer 1.5 trinity kernel and 307 gpu. What benefit are you seeing versus the other trinity kernels with higher gpu and lower overclock limits? Are you running your phone at 1.5?

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.

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.

I tried the best I knew how and I couldnt kill the battery for 2 days. I ran everything at once (not truly everything) and it just wouldn't die.

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.

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.

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.

Battery life thread

Edit : Battery is now fine on the phone for me ..
it seems like the phoen (stock kernel /rom) doesnt go to sleep as well as it should ..
here is the original post ..
Never inserted sim card on mine .. installed all my apps..
That's it... Over night it lost 30 percent..
At 9 am it was at 70%..
At 4 pm phone was 0.. turned off...
I did nothing.. The phone had screen off all day never used it once.. It was in my car ... nobody touched it..
I'll give it another chance tomorrow but if that's the battery life to be expected I'm returning this bad boy.. Please share your stats...

I can make it 24hrs with moderate use. It has gotten better over the past few days. Attached my batt stats. One gmail, one pop, and one exchange account. Near 200 apps installed.
Your phone may be wigging out over the no sim.

I get great battery life. A little better then my note2. How you been man, its been forever.

I'm getting insane battery life compared to my Galaxy S3. Took my phone off the charger at 8:20 AM. Email syncing with Gmail and an exchange account. I left LTE on all day. Downloaded some apps and an audio book. Listed to an audiobook during lunch and several hours this evening.

My battery life has improved significantly since yesterday. Google services killed me, but has calmed down. When all day, 12+ hours, pandora, gps, and 4 hours of screen time still had about 40%.

return it.. get a new one.

Might want to check for partial wake locks as well. Had a few apps on my Note II that kept it from sleeping with the screen off. That will eat battery constantly. If so, either dump the app or root and use greenify.

Just a tip for anyone getting "okay" to back battery life. If you go into wife settings and turn off location something that helps and if you go into maps settings and turn of report location services that does wonders. I was getting about 4 hrs sot which isn't terrible but it isn't wowing lol so I did that and in the last few hours I've added another hour of sot and the % went down about 6 which is just a massive difference and trust me I use my phone lol not just reading I'm dual screening working and typing and what not. So that may help.

Check my last post and do those things then test it. I'm not rooted and my drain was happening like yours and i turned those multiple location type settings off that continually wake the device and now battery life is better than great

Mine has better battery life than Note 2.

I have had amazing battery life. I was over 2 days with light to moderate use.

My battery drains about 1% for every 5 minutes of screen on time. Is that good battery?
Sent from my SM-N900T

i put the wifi scanning always on to back on yesterday
it helps with GPS location

download greenify from the market and kill the apps that are running in the background

i didnt do nothing since yesterday . my phoen was here default settigns lost 5% for the whole day . so its good news .

Download DS Battery Saver. It puts your phone into a deep sleep and shuts everything off and wakes your phone at desired intervals, therefore you don't have apps constantly waking your device for requests which put a strain on your battery life. Give it a try, you'll love it. It's especially useful if you're working or something and you don't need your phone as much.
