Any tips for saving battery in bad signal area?

I know this is normal but it seems like its the worst with my thunderbolt. If I'm in a bad signal area, my battery just tanks. Worst then any other smartphone I've ever had. I'm running CM7, but I'm pretty sure it did the same when I was stock. I know I could technically go into airplane mode but I don't want to do that. Does turning off data help at all? I don't have any sync turned on so I don't think anything is trying to connect that can't but I'm not sure. Any hints or suggestions?

when I'm home I constantly have X cause I'm in my basement. I just have the Toggle switch set to 3g since 4g isn't available.
Go into this and whats your biggest drain? (i keep display at 50% 100% of the time)

Right but doesn't your phone still search for signal then?

Well IMHO, one of your biggest issues is that you're using CM7 in the first place. I know plenty of people have great battery life with it etc. etc., but I'm with you on this one. I work in a restaurant 14 hours a day with horrible cell phone reception cause the building is just all concrete. My phone just diesssss, but when I check into my battery life, its all ass backwards.
Take scoobarSTI's picture, and look at your battery info. You'll see that Display for you is probably taking up 5% of your battery life. 5 F-ING percent. While android system, cell standby, and cell idle take up an estimated combined 70% or so. It's just something with CM7 i guess. Hes using a sense based rom. For right now, CM7 clearly still has is quirks, but for great battery life with bad reception, CM7 just ain't gonna cut it.
I did help myself just a teeny bit, and that was by setting profiles in SetCPU. It gave me maybe an hour extra a day to my battery life.

lol I dunno. I know pretty much the whole time I'm in my room I have n X for service. Been here all day because with heat index it was like 108 today.
I'm running Gingeritis 1.2 it's a different GB build then the leaked version out now.
I was running cm7 and loved it, but wanted to try this new GB build out and I'm loving it.

Weird thing is, is that if I'm in decent to good signal I get awesome battery life. So for me its not like I always get bad battery life, just wanted to know if there was any tips to help with this.

try this app and see if it helps. Your phone may be searching for signal but I know finding 4g signal kills its quick.
https://market.android.com/details?id=net.andirc.lteonfoff&feature=search_result

automatically connect to wifi "if" the place you are at has it.
get extended battery
try another rom
thats about all i can suggest. good luck!

All that app does is do the same thing as hitting #*#*4636*#*# on your dial pad. Take you to a "testing" menu and hit "Phone Information". On sense roms, you'll have "CDMA Auto/LTE" (or something like that) selected under "Set Preferred network type". On the AOSP roms, we have it selected as "Unknown". If you switch out of "Unknown", i'm pretty sure, you can't reselect it, which means no 4g. We have the equivalent to this in our network setting menu.
I just never found much of a difference in toggling between 3g and 4g in AOSP anyhows

Not positive why, but Slayher used to tweet that it could bork your data to the point you would have to reflash the rom

Well today I went with just toggling data off and it seemed to have helped with my battery life. Not sure if I just got lucky and had a good day at work or what. It happens every once in awhile but hopefully that works for now on.

Switch your phone to CDMA auto (PRL) to disable the LTE radio at least, otherwise all you can really do is put it in airplane mode. IMO signal loss is the number one problem with battery life on the TB, especially if you don't have a 4g signal.
Depending on the rom you're using, there may be a shortcut in settings, otherwise dial *#*#4636#*#* to get to the radio options.

[Q] Which custom rom/kernel is best for battery life?

I am currently using AOSP+ with the speedy 5 kernel and its chewing up my battery life like theres no tomorrow. I'm dropping at an average of 10% per hour. Autosync, brightness, update intervals disabled or turned down to minimal. My wakelocks are normal. The thing that bothers me the most is the Android OS that's chewing up 45-50% of my battery life. I never had this problem at all with gb. I can go 16-17 hrs without a charge.
Any suggestions would be appreciated. Thanks!

Try haka's kangy-8 with Eugene's speedy 5 sio kernel

Try downgrading to the Speedy-4 Kernel. I'm running the latest AOSP+ rom with the Speedy-4 kernel and my battery life is excellent. I can post a download link to the Speedy-4 kernel if you're interested.

I have the same configuration, Skype used to eat most of my battery and I think this is because Skype haven't update their app yet. I don't use maps or location services, but I noticed that google location service is always on, I forced closed it ( it gets back sometimes) Anyway, after closing skype my battery performance is ok. I used to lose 10%/ hour even if the phone was idle, after these mods I think I lost less than 5% in three idle hours.

Most of the custom ROMs and kernels are rubbish, aren't they? I mean if people really knew what they were doing, they'd work together with kalimochoAz on the official source. Or at least port it back upstream once they've got it working...

What?! No, wtf kind of comment is this?
I personally run AOKP Milestone 2 with Steve Garon's 1.12 kernel and my stock battery runs 30+ hrs with fairly heavy usage.
AOKP/Garon have awesome features above and beyond cm9/kali at this point, and performance has been flawless.

Which ROM, and is it overclocked?
Also it would be helpful get a screenshot of YOUR battery screen, you said that the one you posted is not yours, but it is similar..
There is a reason I asked for that, I will be able to help a little more with YOUR battery screen, it will help figure out what is eating the battery on YOUR phone.

Turn of Wifi unless you are using it, as well as bluetooth. Both of these will actively scan for connections while you have them enabled. Also, turn off Automatic Brightness in settings/display, and see if that helps...
Looks like you are running SCv5 or v6, and you shouldn't be having any out of control battery consumption issues with this rom.

I see that you have lost 33% of your battery in a very short time. That is an issue.
Ok two things that I can think of right off.
Which ROM is this that you are running?
How long have you been running this ROM?
Sometimes the battery stats can be off until you get SEVERAL full charges and full drains on the battery after a flash.
Also you try and reset your battery stats.
Try using this app from the market:

scv6 has much better battery life. you can just get another launcher from the market. I use launcherpro. lithium is pretty good too, but the battery doesn't even compare

I would suggest going to the market and installing bad ass battery monitor and run it for 24-48 hours. Its helped me track down battery drain before. Also better battery stats here on xda is excellent for tracking wakelocks. If you don't know what a wakelock is then please Google it.

just install launcherpro then the next time you hit home it will ask you which one you want to use. you will have to re setup all your icons and stuff, but that is the case with any new launcher

I've been on SCv5 and now SCv6 for a while now, and I have both Holo Launcher and ADW Launcher EX installed on mine, in addition to Go Launcher...I switch 'em back and forth fairly frequently. (ADW is my current favorite) Like he said above, once you install a new launcher, it will ask you the next time you press Home which one to use, and you can pick a default. I always get the launcher set up and use it for a day or two without setting a default, just to make it easier to revert. If you find that annoying (which I do if I'm going to be working on my phone a lot) then you can download Home Switcher from the marketplace. It's free, and it works well. For some reason on my phone I had problems with FCs with the normal version, so I installed the "for Froyo" version, and haven't had any problems. This lets you switch back and forth really easily.

+1 ADW Launcher w/y0rk's white, black, or blue themes!

Telus SGS4G battery life and ICS

I've tried many of the SGS 4G ROMS after convincing my Telus SGS 4G it was a T-Mobile version. I really like both remICS-UX and UltraGen ports, but battery life is quite disappointing. 3G/4G was not as good on remICS-UX ans UltraGen.
Any Telus phone users out have suggestions on other ROMS to try, or settings to try for our phone (yes I searched the forums, very few Telus folk here).
Cheers,
BHTM

Flash with hefe kod kernel over your Ultragen rom. You should see a big difference in your battery life. Also turn off wifi and GPS if you r not using it.
Sent from my SGH-T959V using xda premium

The Telus phone is actually the T959P or something and it's reallynot the same phone as they use different bands than Tmobile/Wind does, so I'm surprised the ROM actually works but there could be many things that are draining the battery that are due to the fact that's its not the same phone, and that also would explain why things don't work right in terms in wifi/4g/battery, etc.

Yeah I am totally surprised it worked too. But a few kind Telus users here give easy instructions on how to make it think it is a sgh-t959v. Just hoping they will continue being kind and share there tips and tricks.
Anyway busy thanking and donating to all you kind folks. I'm a happy noob, having fun great fun trying all these custom roms.

Just curious what you did to make it think it's a 959V ?
When you say battery life wasn't as good, can you clarify that? How long were you using it, how long did you have the screen on for, did you change governors to one better suited, can you take a screen shot of your battery window in the settings like this
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Whatever app is listed at the top, in my example, Screen, click on that and take a screen shot, This will show how much time that app has used
If you run something like CPUspy, it will show you the different "states" of your cpu, IE, what speed it's running at. If the phone is in standy, it should run mostly in deep sleep state. If something is keeping it from sleeping, that will affect the battery.
I just took my phone off the charger, but you can see it used 1000mhz for the bootup at full speed, then when I shut it off, it went to deep sleep mode. If there is no deep sleep, then something is keeping it "awake" and that is the cause of the battery drain. Sometimes installing app's can do that.

Much thanks for the tips, I'll give them a try. Playing with CM10 at the moment,but will try UltraGen again later and capture things. Been wiping everything including sdcard, so no media files to confuse media server.
Just realized I should be in Q&A section, bad n00b :laugh:

There is more coming... btw.
someone is sending me a verizon fascinate, and there is some common code between sgs4g, verizon fascinate, and T959P.
The bigger part is cg2900 gps driver, different digitizer, and a few other odd ball differences.
I also have an SK4G that I'm trying to port as well.
A lot of these devices share the same drivers, and our phones are just a little bit different then aries.
Fascinate even has some problems in the aries kernel, although I think they have work arounds for most of them.
So, as soon as I become available (not busy with work from 8am to 3am daily...) and get the verizon fascinate from... someone, I'm gonna start looking at t959p as well.

When you say battery life wasn't as good, can you clarify that? How long were you using it, how long did you have the screen on for, did you change governors to one better suited, can you take a screen shot of your battery window in the settings like this

My daily usage is like this: Get on train, use phone to Netflix, read news (Currents, Flipboard, et al), listen to music from Google cloud or Rdio, screen on the entire time (1 hour 15). Don't use phone for 8 hours. Reverse the train ride. Charge phone when I get home for next day use. Rarely have GPS or Wifi enabled. No media on SD card. Only half dozen extra apps (Currents, Flipbord, Google Play Music, Rdio, Google Maps etc).
The stock ROM from Samsung/Telus did a good job of lasting through day and have enough charge to finish the nightly train ride.
Had a chance to play with CPUSpy and try a few things, no deep sleep on remICS-UX or UltraGen and they would not last through the day (unused, screen black) without being charged. I haven't changed the default ROM performance settings or governors (tried to OC but phone got really hot, didn't really notice any difference is application performance, so set it back).
I've just started trying the SlimBean 3.1 ROM seems to be deep sleeping according to CPUSpy. Fingers crossed it behaves closer to stock ROM as far as battery is concerned (deep sleeps when not in use)
Anyway thanks to mcmerrit for the instructions on how to get this odd variant working with the mod community ROMs. Feels like I have a new phone

I've never been able to get more than 10 hours on a charge with 2+ hours of screen time on any ics roms with the stock battery. I do have wifi on pretty much the whole time though.

Erikmm will have another kernel coming out with battery life as good as GB. Stay tuned.
If it helps, hit the thanks button. It's my motivator to be more helpful.

Slimbeam 3.1 battery life is quite good. Survived my Monday commute. New battery for my HTC amaze arrived today. But I'll switch back to sgs4g as amaze cm is not as stable.

what's the point of a custom kernal?

I am fairly new to rooting and have the op7pro rooted and was wondering what the deal is custom kernals and what the benefits are and how hard it is to use one

Its modification of the stock kernal that can provide extra features, improve performance and battery life. They all are a bit different and there really inst a better one of them all. Its all personal preference so I recommend giving them all a try for a few days and see how your phone performs.

I've seen a lot of good things about elementalx and I just installed it and followed it's instructions and flashed it and should I mess with any options or just leave it as is?

I personally don't mess with any settings but if you happen to I recommend referencing https://androidmodguide.blogspot.com/p/blog-page.html?m=1 so you know what each option does. Also if you want to flash another kernal you can still use EXKM to manage the kernal.

Kernels allow you to modify the governor's behavior or use alternatives, boost parameters, clock speed, memory thresholds, block wakelocks, under or overclock, etc. They're often accompanied by newer drivers (ex. Wlan from CAF), Linux upstreams, fixes from QC, new features like k lapse, and so on.
CPU governors and boost can be tailored to be aggressive or passive. I'm more concerned with endurance than scores, so the latter suits me.

I have mixed feelings on custom kernels nowadays. I used to be enthusiastic, but eventually realized that every rose has its thorns. Some custom kernels are truly excellent on certain phones. Some phones just don't play nice with custom kernels, and you could lose features until you flash a different kernel. Modern Android stock kernels are stock for a reason, in the same sense that some wearable things are "one size fits all". The good thing is that kernels are super easy to flash on a bootloader unlocked & rooted phone!

Which kernal is ultimate speed? Some guy benchmarked 440,000 on atutu, I max out 380k

Flash smurf kernel, you can try its gaming mode.
It is easy to flash and it has an app to change setting.
Im using firefox on balanced mode, my phone is consuming about 5% battery per hour.

I'm assuming you can under volt these phones and get better battery life too with custom kernel?

No, and no need to anyway :good:
(This with stock kernel by the way )

What all have you disabled/done to achieve this?

That also means nothing without the battery graph as the user could have partially charged the phone and that doesn't rest anything until the phone is fully charged to 100%. Not saying he can't get that, I'm getting 9 to 10 hours sot per charge. Just need to show the battery graph too.

That was a great read. I will read through it again if I decide to select a custom kernel.

Different optimizations.
Preciously it meant over clocking.
But currently you can turn off things like ZRAM and swap.

Sky dragon kernel is the way to go
