Why does cell standby drain my batter? - Sony Xperia S, Acro S, Ion

So I don't use my phone while I'm working or if I'm in class. When I'm in class I have just Pandora going but otherwise its nothing else. Cell standby uses 82% of my batter....
Sucks getting like 2 hours of acctual use and I cant get ics on my phone

I had this problem while in training last year for my current job. The training room was a dead zone and the phone was working overtime to try to find a signal.
If you weren't relying on Pandora, I'd just recommend Flight Mode. Worked a treat for me. Maybe just try setting it to not use 4G while you're in class and see if that helps.
Nowadays, I have a 64GB SDXC card with about half of it loaded with music. Don't need TuneIn Radio (or other streaming options) unless there's a specific musical itch my collection just won't scratch.
Also, getting ICS on the 'unbreakable' AT&T phone was far easier than it sounded when just reading about it. Have a look at the various threads and just remember that 'Step 1.bat' won't tell you that it's succeeded. XD
EDIT: You know, I was just looking at that screenshot... 8 hours on the battery, and it's barely dipped at all, judging from the graph on top. '81%' just means that 81% of the drain was due to Cell Standby.

Yea it looks to me like your getting some good up time there. One thing I noticed with Pandora is the adds will cause a heck of a drain on battery and chews up quite a bit of data as well. I personally use a add blocker from the market and a app manager to keep stuff optimized. I also use a add free Pandora I found here on XDA but mainly for data reasons since I only have 3gb.

LTE can drain battery pretty good. Mine isn't as drastic as yours though.

Today I went from 65% to 30% in an hour... I want ics! another question. Can we increase the limit on how large a video we can small? Gosms allows up to 5mb I think and the quality of the sms size is horrible to say the least.

Battery not lasting and i got it on friday

Ok so how long do u have to see some good battery im on my 3rd charge and its been lasting me 6 to 7 hours but i have only text and some surf and a bit of gaming i am on the latest stock rom rooted and i have hotspot hack and sprint boot that i installed

That's pretty terrible even if it's not conditioned yet. Especially because it sounds like you have only light use. You may want to take it back and replace the battery. Either that or you're in an area with terrible signal.

Take it back and get a new one. I just bought one on friday and even with heavy use my battery has lasted 20+ hours.
Sounds like a bad battery then. Happened to me on another phone. I just asked for a new battery and they gave it to me no problem.
I don't even have full bars and I get a minimum of 12 hours on pretty semi heavy use. I don't use wifi and I get at least 3-3.5 hours of screen on time.

A sales only store is unlikely to have any batteries on hand, we hoard a ton of new and used ones at my store, but we're a repair store...we're always getting folks coming from sales only stores for batteries.

Excellent news, glad it worked out. Where did you end up getting your battery? And if you don't mind me asking, how much did it set you back?
Apps like Facebook would drain my battery really fast. I use friendcaster now. Also make sure your not using the wireless location in the gps setting.

Phone over heating while being used on the mobile data

I just added a data plan , I was using the phone exclusively on WiFi,I noticed the device gets real warm when using the phone when the mobile data is on(by using the phone I mean, surfing web, streaming music and GPS navigation)
Is that a common problem, or it's just with my device, that I should seek help for?
Btw,I upgraded to ics through kies last month....

Do you have an app that tells you your device temp. It could be normal, but it's hard knowing if you don't know the actual temp.
I've noticed when using the radio vs WiFi, my device runs warmer. High 80's, sometimes higher if I'm running it a lot. WiFi always seems to run cooler.
Sent from my SAMSUNG-SGH-T989 using Tapatalk 2
As long is it is not burning your hand, then it's perfectly fine. Most phones tend to warm up during use. You can perhaps try a different kernel if you are rooted and undervolt, some people claim it helps. If not then don't even stress unless it hurts to hold the phone.

Ha! Try hours with GPS, Bluetooth music and Tethering on... the heat seems to really hit while I'm charging and doing all that. Fact! I can't touch the ass end of the phone. It probably gets about 8 hours a week like that. Still working perfectly. Samsung tells me it's normal. It also has a lot of factors for me too. I use a 1 amp charger. After 96% it's not so bad. At night when brightness is down. Not as hot. I tried to get it to mess up but couldn't. GPS, Bluetooth, tethering, charging from 30% and 100% display, and I pushed out to a low coverage area. Didn't miss a beat or melt. Lol.

Navigation makes phones really hot, but with normal usage it should stay within 30-36°C.
I like this phone's heat management more than my old phone. My Evo 3d would get hot from 10 min usage.
On this, my screen has been on for 2 hours straight and I'm running at a cool 35.1 °C.

When I was running CM10 for a day or two I thought my phone would melt but it was also 90+ degrees outside so it was hard to tell. My phone gets a little warm, but nothing too worrying.

It actually shouldn't be expected. The Snapdragon S3's also ran at 1.5ghz and was pleasantly cool and the Exynos on the Galaxy Note was at 1.4ghz. Both are less power efficient and should run hotter than the S4. I've used the Evo LTE for a while with the same S4 and it barely got warm on a hot day. The issue is with the second core being weird. For those that hasn't already, make sure you flash Freeza's fix, http://forum.xda-developers.com/showthread.php?t=1790061 . This fix made my phone cool and got rid of my quickly draining battery life.
Most of the time my phone will stay within "normal" (to me) range, but when I game heavily... it turns into an oven range! I've gotten so paranoid a few times, I took the battery out and let it cooled for 5-10min
Im having the same problem....it isnt the software thats causing this its the hardware
Sent from my SPH-L710 using xda premium
I hope you guys will repsond to this... What do you consider to be "normal" temperature for your phone to reach? Is 35 degrees realy normal? Ive heard people with s3 talk of theirs only reaching temperatures of 29 degrees max.
Thanks.

I get phenomenal battery life out of my S3 (stock).
I had an Epic 4G and was afraid to leave my desk because of the battery drain. With moderate usage (30-60 mins talk time, texting, chat, some web, exchange, ect) I can easily get 16-20 hours. Signal quality in your area will impact it more than anything. Also, wifi is vastly easier on the battery.

You can improve battery life by switching to custom roms with less bloatware, and updating to more efficient kernels. (This is on a Rom/Kernel level)
Software wise, just figure out what apps are causing wake times and try not to use them. Basically whenever an app/widget refreshes/updates content, it may cause phone to wake (like weather/clock widgets for example).
I have been using cpusleep and it seems to have helped my battery life ... also using a custom rom without the bloatware is key for me.
my current setup is freegs3 release 6 with the latest trinity kernel...even though its overclocked my battery has been amazing and phone has worked flawless.
Im also using system tuner which has given me the ability to manage the cpu with on demand and other customizable settings
The only thing I synch is my k9 mail account
I also have frozen several samsung apps which helped...
Im now getting over 20 hours of basic use between charges...I dont use games/videos so might be a little skewed . I use this phone for business calls/internet/messaging/photos/navi...pretty basic

I have been using Gigajoule lately by feckmu and it has given me the best battery life out of all the custom roms I have tried.

I, personally, don't focus on battery life at all. I run Bluetooth all day, listening to my music, play games on it during my lunch hour and other times throughout the day and send texts/emails off and on all day, and it's down to about 40% by the time I leave work on a normal day. That's unplugging at around 7:30AM, and leaving work at about 5-5:30PM, so that's about 10 hours mid-heavy consistent usage.
To me, as long as I get my full day out of it, I'm perfectly content with it. I don't need my device to be a battery warrior, I need it to be a power beast and do what I want it to do, when I want it to do it. I personally dislike apps like Juice Defender and those that disable radios and data on me. I also don't like using CPU scripts to limit the CPU, undervolt it and all that. To me, it just seems contradicting to buy a powerhouse like the S3 and then strip away it's best and most powerful features. I also don't like the small influx of bugs that arise when you start doing things like disabling data and limiting the CPU/voltage. I like my smartphone to be as smooth as possible, all the time, without any hitches/bugs.
I'm a very heavy user and rely on certain notifications as they are sent out, so extending the battery by an hour or two is the most I could hope to gain by using these apps/scripts, and the level of frustration that come with them when I get syncs late or things are sluggish isn't worth it, imho.
Don't take that the wrong way, I'm not saying they are bad apps at all, nor are the CPU scripts completely pointless. I would give them a high rating if asked, because they do their functions well. I'm just saying they don't work for the way I use my device.
2nd day on Goodness 7.03 with the stock kernel, considering my average use it's pretty sweet by the end of the day.
