Hi Guys
i've heard that you can turn off the gps which would imply its permantley on, is this true? If so, any one know how to turn it off as I can't find what is probably an obvious menu/option.
I need to turn it off as i am only getting six hours of idle on any charge of my phone - have an extended batt on order and it is using push email (constantly connected) which is a must for me.
No real complaints apart from battery (which was expected and being sorted) and seems pretty good so far.
Oh, anyone else ditch touchflo? Thought it was rubbish myself
If GPS was able to be turned off, how much battery might it save? The difference could be transforming!
I personally don't think that GPS would be permanently turned on.
Maybe the interface, which "looks" if a demand on GPS data exists...
IF the GPS would be permanently turned on, the battery drain would
be very high, and the device would get assumingly very hot.
mine eats battery more than a fat bird eats bugers and mcdonalds and yes, its very hot as well .. although, this could be coz its pretty much always plugged in.... ?
GPS is only 'on' when it is called for by any external program. If it were on all the time the phone would be flat in about two hours regardless what you did with it.

do you KNOW that or are you assuming that?
I know I have seen programs that turn it off just as usual, the search on here has let me down. If this was definetly the case, then why would programs like these be written?

Yes, it is a known fact that the Diamond heats up when you are charging it (to levels some may find concerning) but HTC have dismissed this as 'normal operation'.
If it was on all the time you would have an instant fix on where you are straight away .
If it was on all the time your battery would last as said around two hours
I think it is in standby mode if this is what you mean but does need software activation to enable it on as in transmit and receive .
Not sure if turning off standby mode would be a good idea but if you google for the chipset name and have a read up it will let you know these kind of things
Are you sure you guys are not getting confused with GPRS, not GPS?
That can drain battery life, and by disabling GPRS Auto Attach using Advance Config tool, can extend your battery by around 40%!

Some battery threads:
http://forum.xda-developers.com/showthread.php?t=978269
http://forum.xda-developers.com/showthread.php?t=1004760
updated tl;dr for most of you lately:
Your problem is probably that you flashed a new ROM or kernel recently, which causes battery stats to be very inaccurate. The most common symptom is that suddenly the battery drains like crazy, when before it just dripped. The opposite can also happen - you flash a new ROM and it seems like the best battery life ever. Until it suddenly jumps from 60 down to 10. This can happen even if you erased stats after flashing. You need a few days with your new ROM first, then you should see what your battery usage is really like. Do full charge cycles to speed up this process. (Bump charge, erase stats, drain, charge, don't bump charge or erase stats anymore, drain, charge, drain, charge, etc.) Simply put: you cannot judge battery performance after flashing a ROM. Often it can be a week or more before battery performance and battery level reporting becomes stable.[/tl;dr]
Every time a chef makes a new ROM available, or even among those using stock OS, there seems to be wildly inconsistent feedback on battery life. Many report catastrophic battery drain, while others using the same hardware/firmware/kernel/ROM say it's the best battery life they've ever gotten.
It would seem that a battery can run away on you for a variety of reasons, and flashing back, or returning to the store, doesn't have to be the first thing you do to fix it. This thread is to consolidate many of the complaints around xda about sudden battery drain, and discuss proven (or superstitious) fixes for it. This is not another discussion on tips and tweaks to extend battery life. There's a good wiki on that already. This is specifically about when you experience an unexplained dramatic increase in how fast your battery is draining, and the usual tweaks aren't having any effect.
And, in some cases, if you are experiencing battery drain associated with one of the "more interesting" issues below, you might be experiencing lag for the same reason. Please attempt all of the below to the best of your ability before making a post about battery drain or lag with a particular ROM or kernel.
We'll start with the simple.
Don't rule out your imagination or neurotic behavior as the main problem.
I hate to open with a "shut-up-noob," but this one is real. I know I've almost fallen victim to the disease of "let me turn on the screen just one more time to check the battery %." Or hours of "man this new lagfix is great watch how fast I can swipe screens and load apps over and over!" Both of which, obviously, result in more battery usage. Then there's also the case where you just installed a numerical battery meter for the first time, and watching it tick down is weighing on your psyche much harder than the previous, barely noticeable movement of the bar and making you think your battery is draining wildly. Which then can also then lead back to disease #1 in a vicious cycle of psychosomatic battery abuse.
It may just be the battery itself. Some are reporting an apparent quality control problem with the batteries. You might get a great one, or if nothing below helps you then maybe you got a dud. I can't help much there. Try reporting the problem to AT&T or Samsung. I hear AT&T is a lot better to deal with.
Check the basic battery usage stats. Settings -> About Phone -> Battery Use. This won't necessarily tell you a whole lot, it isn't always accurate, but it can give you an idea of what the system thinks is using most of the battery. Such as whether it's playing with the screen too much, or making a lot of phone calls, etc. Keep in mind... I'm pretty sure that these stats are only based on the time period listed at the top of the screen. A lot of people get confused when it shows the display using 90% of the battery. But if that's only based on the 30 seconds since you unhooked the charger, then it isn't all that confusing anymore.
Be wary of the "battery full" status. I have repeatedly found, at least in leaked 2.2 ROMs, that this alert actually goes off long before the battery is finished charging. This bug often continues even after you've done all of the other various tricks and tweaks and recalibrations. It says "100" and that the battery is full and to disconnect the charger, but when you disconnect, it instantly drops into the low 90s and drains quickly from there. Rather, if you ignore the alert and keep charging for considerably longer, it will actually be at 100 when you disconnect, and will drain slowly.

I'm quoting out the above, since I can't find the strikethrough tag. With new accurate battery mods, this isn't true anymore. Your battery doesn't need to go to 100%. It will be high-90s when you unplug, this is normal.
Drain and charge.
Sometimes the battery meter will seem to plummet, but then sit at <10 for hours before it finally shuts off. Giving a full drain may help calibrate where the "zero" really is. Run a long video, or just leave the camera up, until it shuts itself off. Then charge it back to 100%.
The bump charge (now commonly referred to as recalibrating).
Maybe your phone forgot where zero really is, or maybe he forgot where 100 really is. Here's the bump charge. Read carefully; I did it wrong for a while before I got it right. Charge the phone to 100% while it's on. As soon as it hits 100%, unplug the charger and power off. Now plug in the charger while the phone is off, and charge to 100 again. As soon as it hits 100, unplug the charger and power on. Wait until it boots completely, then don't charge this time, just power right back off. Now charge to 100 one more time with the power off. Power on and you are bump charged. Many also consider a stats wipe to be essential to this process as well. See below.
See joeybear's post (linked below) for more info on bum charges and battery stats, such as different procedures for CyanogenMod.
Erasing the battery stats (for you rooters/flashers)
Sometimes you just want your phone to forget everything he thinks he knows about his battery, and re-learn it from scratch. Your phone maintains a file with statistics on battery usage, which in turn is used to help calculate battery life at any given time. Sometimes, especially if you've been playing with ROMs, kernels, and lagfixes, the stats in the file just aren't applicable anymore to how the hardware is being used, so you get crazy battery drain.
Clockwork Recovery has a simple function to wipe the battery stats. If you can't run Clockwork, use ADB or a terminal emulator (search the market) to delete that battery stats file located at /data/system/batterystats.bin. The link at the bottom to joeybear's thread has a little more info.
The general idea is to start by trying the above - make sure it isn't your own fault or maybe just a bad battery, then drain, bump charge, and wipe stats - in that order.
There are lots of ideas about what may or may not happen when you experiment with the above. Wiping battery stats after a ROM flash that already wiped them for you is at least redundant and may even contribute to a battery drain problem. Some say you should wipe first and then drain and bump charge. Be careful about wiping stats and bump charging too much, though. Over-charging your battery will hasten its demise.
HOWEVER, if you're like I was when I first started this thread, you've seen the above recommended many times, and none of it has ever helped you one bit with an actual sudden battery drain problem.
Now for more interesting work.
Occam's razor. The simplest answer is the most likely. Battery appear to be suddenly draining faster? Well, it could be that you need to retrain your phone (or your mind) by using the procedures above. It could be that your battery suddenly went bad. A more simple answer is that something is draining your battery. Something is abusing your CPU, your memory, or your network interfaces. Try to find out what, or at least stop it even if you don't find out what. Simply looking at the stock report of battery usage isn't likely to tell you everything you need to know, though.
If you've recently flashed something, try your flash again, and this time be more aggressive. Make sure you turn off any lagfixes you've installed beforehand. Make sure you've got the most charge you possible can before flashing (see above - you want a true 100% charge immediately before flashing). Take the plunge and opt for repartitioning, data wiping, formatting, master clearing, or any other options you may have to start with a clean slate with the new ROM. Even flash stock first. Pay close attention to battery usage as you re-install apps and get your phone set up again. It may be one app in particular that was responsible.
Uninstall all task killers. Yes, uninstall. I know task killers are supposedly battery savers, but 99% of you (including me) don't know what we're doing when we get our hands on a good task killer. It is very possible you've got one service that is constantly trying to load and call home, and another that is constantly auto-killing it. If you really want to include task killing as part of your phone maintenance and battery tweaking processes, then download an app that is specifically designed and configured just for battery efficiency, not a general-purpose task killer that will allow you to hose up your Android system.
Check your background syncs. Experiment with turning them off, one at a time, and see if there's improvement. The app may have gotten confused after all your flashing and is doing something crazy as it syncs. If you isolate one that makes a difference, reinstall it or try living without it.
Live wallpapers. They actually improve your battery life, no lie. Ok, actually that is a lie. Some of them look awesome, but many users, myself included, experience a significant increase in battery drain when there's a fancy full-screen animation running non-stop on the phone. Try getting rid of them and see. There are some nice, simple, dark wallpapers that don't animate but are still pretty enough to impress the ladies at the bridge club. Live wallpapers can also create some majorly noticeable lag in your other apps, too.
Install OSMonitor. Set it to sort process by load, descending order. There shouldn't be much in the list, the OSmonitor app itself should show up near the top, at around 20%. Other apps should be in a 0% wait state or occasionally grabbing a few %. If you recognize an app sitting consistently at 50%+, that could be your problem. Make sure you know what it is first (not a critical system service) and try uninstalling it.
Is kswapd0 taking a lot of CPU? This is the memory swap / page file process. It's normal for it to be grabbing little chunks of CPU here and there, but if it's sitting at a high %, or jumping in frequently to a high %, then something's going on with your memory cache. Unistall your lagfix and try a different one. If you aren't using a lagfix, get OCLF and use it to install EXT2 and then OCLF V2+. Despite the changelogs and debates that claim otherwise, several have found OCLF to be very useful after flashing to any Froyo ROM (unless that ROM already includes a lagfix such as voodoo or stumpy's). If none of that works, your kernel may be the problem. Swap it or go back to stock.
Look at data/network usage. If you have a router or other device on your home wireless network that can give you some info, try that. Does your phone appear to be trying to send or receive an unusually high number of packets/data even when you're not doing anything with it? Also, while off wifi, watch the little green and red data icon in you notification bar (the 3G / E icon). Are they spasming green and red constantly every 2 or 3 seconds, even when you don't think you're doing much data transfer?
OSMonitor can also again be your friend here. Under "Network" you can expand each interface and look at live data transfer #s. Does one of them seem to be really active despite you not doing anything in particular with your phone right now?
If you have any of these signs of heavy data usage, go back to OSMonitor and look at Connections. Turn on DNS reverse lookups in settings. Turn on some whois. Ignore any loopback (127.0.0.1) and likely you can ignore the 1e100.com stuff, that's just Google (get it? 1x10^100). Are there any other established connections? Does the reverse lookup (the domain name) indicate what application might have the connection open? For example, if it's weather.com, that might be a Weather Channel widget or app. That one was responsible for destroying my battery one time. Use whois and similar tools in OSMonitor and on the Internet to help you figure out what your phone is connecting to. If you've got heavy data usage and an app or apps have open connections, uninstall / reinstall those apps and see if the battery drain stops.
Under-volting. Xan's Voltage Control App. There's a lot more of this going around now that there are several overclocking and undervolting kernels available. There isn't a whole lot to be said here. Different CPU clock steps can be individually adjusted to pull a little less juice from the battery. Make sure you keep them as temporary settings and do not "set on boot" until you're sure you've got a stable configuration. If you set something to a level your phone can't handle and script-save it for booting, you might not be able to boot again. Anyway, under-volting will not suddenly revolutionize your battery performance, but it can help.
Also, switching UV settings can significantly affect your battery meter after reboot. If you've recently switched UV settings and rebooted, your battery meter might suddenly show 20% more or less batterly life than before. This is simply what the meter thinks to be the case, obviously your battery did not just jump 20%.
Backlight notifications. I don't have hard data to back it up yet, but I've noticed that when a backlight notification is active, my battery starts racing to zero.
Cyanogenmod. It's available on Captivate now. It isn't stable/supported. It has a lot of debug code enabled. That means it uses more battery than it will someday when it's stable RC and debug code is commented out.
I've successfully used all of the "interesting steps" above in different cases where I had sudden battery drain and the basic steps didn't fix it. Anyone else have success with these? Any other tactics to share? Please post.
Thanks to joeybear23 for good info on recalibrating the battery.
Great info on the battery.
And you mentioned Occams Razor... the simplest answer is the most likely!
Ok, maybe your batteries are actually no good. Many have found theirs to be faulty and that after replacing them all is well again.
I just got a spare and the new one is great!
Maybe a batch of samsung batteries has problems and they begin to lose charge quite quickly after they have been in use a month or 2 (Or they get confused after multiple Flash's of ROMS .
Basically, I bought a cheap aftermarket battery as a spare and decided to try it in my phone today. I have made several calls and installed some apps and have played around with the phone as per normal. After 7 hours it is at 53%. MUCH better than before. With old battery it would be at 10-15% after a day at work.
Only thing different is I did install the lag fix over the Beta 5.5 to see if it helps speed.
Is it the battery or the phones software causing the problem??? Well if they have a chip in them maybe it IS the battery...???
Great read there! I haven't really been having any problems with battery life lately, but installed OS Monitor anyway just to see what was running. Nothing too out of the ordinary, as everything seems as you say it should be. OS Monitor is up there at 15-20%, android system is at another 8-10%, and system/bin/sensorserver_yamaha is running at anywhere from 7-16%. I assume this is the sensor that monitors what position my phone is in. Other than that, I don't see any other process taking more than a small slice of CPU or so from time to time.
I have done all of the suggestions before; bump charging, draining, and wiping stats, but I also feel that there may be differences since I am using a few different batteries. If I seem to get amazing battery life from a battery after wiping the stats and then using it til it dies, when I put in the next battery, it may work differently, thus screwing with the stats yet again. I have tried to not be as worried about battery life, especially since I have multiple batteries, but it's still something of interest to me.
I'll be subscribing to this thread, and look forward to reading some other users' thoughts/experiences with their batteries.
Scott -
In my own experience, putting lagfix on cog 5.5 has a huge beneficial effect on battery drain. I'm not sure yet but I believe the Unhelpful kernel uses a lot of cpu trying to manage swap unless you put an ext cache on it.
However, it's also true that you can great great life out of a new battery for the first 2 or 3 charge cycles. But a battery suddenly draining faster than normal is probably something your phone system is doing and not a bad battery.

Also, Demented, don't forget to look at antennae/network abuse, not just CPU. I once had a malfunctioning weather widget that wasn't using much CPU but was going berserk on my 3G and sucking batt juice so fast that you could hear the battery whimpering a little bit.

Some of the stuff there is valid; not sure I agree with using the task killer or the advice about leaving "Use Wireless Networks" on and GPS off. I leave both off, and when I want GPS access I turn on the GPS from the power control widget.There's no need for your Wi-Fi adapter to always be searching for networks and associating with Skyhook, etc.
Regarding leaving Wi-Fi on rather than 3G, it does make sense when you are using data. However, if the phone is idle, I doubt leaving the Wi-Fi card enabled will actually save battery life, as it will have to maintain connection with the access point (see your Wi-Fi sleep settings). I think a few short bursts of 3G download/upload when syncing, etc. will be less drain on the battery than leaving Wi-Fi enabled just for those small amounts of data that will be used when syncing. But, if you always want to be ready to browse, or do a lot of DL/UL at a moment's notice, I could see how keeping it on would be justified.
If manually syncing is acceptable to you, then by all means turn off the background data and auto syncing... personally I feel like the phone is really being limited and you have to balance utility and battery life, so I leave those options enabled.
Just some thoughts, if anyone can correct me on anything, I'm eager to learn.

I'm not really sure what you mean by that? There is no swap in use unless you add your own script to mount a swapfile.

Sorry I wasn't being very accurately descriptive there of what I've seen. I rarely know for certain what caused or fixed a battery drain issue. Thanks for calling me out on this one, because going back over my history on this it looks like I was largely mistaken in thinking your kernel had much to do with it. One of my worst experiences with battery drain, it seemed that I had some apps/widgets that just didn't work well after the kernel swap, but Cog also made some non-specific references at that time to battery issues with the kernel and that stuck in my head. Another time with a Cog ROM I believe I may have misread the changelog and I was under the impression that I was on a new Unhelpful kernel, when I wasn't. Looks like that time it was actually a stock kernel partly responsible for the drain, which makes sense. Was I totally confused thinking Cog 2.2B5.5 uses an Unhelpful kernel?
As for what I was seeing (thinking now it was actually not on your kernel), kswapd0 was going berserk on my CPU. All I know is that is generally the name of kswapd0 is referring to virtual memory management, and putting OCLF on fixed it.
Well, vm also allows clean pages that are backed by files to be "swapped" out by freeing them, without using a swapfile, because the data already exists in storage.
A release or two ago I had some battery drain issues that were resolved by reverting some config changes.
Cognition 2.2 can't use any of my kernels, the froyo leak uses a different kernel version, and we don't have Samsung's modified sources yet.

Right, which makes sense when I look back over my flashing history. DG had two versions in one changelog, and a line about re-adding your kernel to Cog 2.1.7 slipped in between some changelogs about Cog 2.2 beta releases. So I originally misread and figured that you'd somehow made a 2.2 kernel. It started draining my battery like crazy, which is exactly what happened the previous time I used an Unhelpful kernel (though again probably unrelated or only somewhat related to the kernel), and so I figured I was on to something. I was wrong. My b.
The issue that still remains is that I believe many people who flash to Cog 2.2.B5.5 (and perhaps 6), without master clearing and stocking first, end up with some odd behavior with whatever kswapd0 does (e.g., odd behavior like constantly using up to 90% of CPU for no dang reason). This is probably a cause, or the cause, of the Lagfixgate scandal and maybe Sudden Rapid Battery Drain Syndrome. And for whatever reason, OCLF fixes it.
I master-cleared and flashed 2.1 stock and then Cog 2.2B6, and kswapd0 and lag are no longer an issue even without OCLF. Battery is too soon to tell, though. Seems to be fairly normal, but not as good as some of what I used to see on Eclair with various other kernels swapped in.
Great resource here. Please keep updating! Subscribed...
Although you can't see it so well in the vid, the lagfix demo I captured also demonstrated a couple of points of battery life improvement.

With any of the 2.2 builds my cpu runs at constant 10%. We know its beta but worth looking into. Only info i have seen on my phone was android system. So im unsure what it is. Havent tore into it yet. But that was all stock with no apps installed. Even cog 6 i have the same cpu readings. So who knows.

Just a tip. I was using latitude and wasnt getting the normal battery life i usually was when i wasnt using it.
I didnt know it was effecting it though cause you dont see it in task manager but you will in applications/running services. Anyways i signed out of latitude and battery life is back to normal.
It wont be remarkably better but it was noticeable to me. Just a tip.

How does that compare to when you're on earlier (eclair) builds? I expect there'd always be a little utilization going on.
Well, hi guys, I have been a member on this forum for quite some time but due to bad memory I forgot my account so I made a new account, that's not my point of this topic.
I bought a new Galaxy Note and I simply love it, awesome phone, but I noticed something wrong. Yes! the battery...
My battery simply dies in 2 hours of usage (videos or listening to music while playing Wordfued)
I want a solution for that, I have my warrantry and all, shall I demand a new battery or something? I'm Swedish by the way.
And I'm sure you'll ask me about flashing a rom and root it.
I know that would make the phone faster, but I'd rather wait for the official ISC.
Only if I can do both of the things at the same time, if so then I will flash, please do read everything so you can watch from my prespective, thanks in advance.
That's definitely not normal. I get much, much more usage doing the same, so I would definitely try changing battery first and then changing the phone as a second option.

1. Flash and test different kernels in case of battery drain. Some are easier on your battery than the others.
2. Use Titanium Backup to freeze or uninstall crapware. This list is a useful guide as to what can/can't be removed from your system: https://spreadsheets.google.com/spr...SENVeXlqUm5vV0E&single=true&gid=0&output=html
3. Set Brightness to low value, disable autobrightness
4. Disable or scale down vibration and haptic feedback
5. Automatic syncing of your accounts is battery consuming. Sync manually if you can
6. Set screen timeout to 15 seconds
7. Disable fast dormancy (dial *#9900# and do it from there)
8. Don't keep your WiFi/Packet Data on all the time. However, if you must have WiFi on the second you wake up your phone, go to Settings/Wireless and Network/Wi-Fi settings - once in Wi-Fi Settings, hit the menu button (the bottom left one), choose Advanced/Wi-Fi sleep policy/When Screen Turned Off. This way your connection will toggle on/off depending on your screen on/of state
9. Disable location services via wireless networks - are you travelling that fast that you need those?
10. GPS is heavy on the battery, therefore use it sparingly
And don't use Juice or any other battery 'defenders': they keep running in the background and consume your juice by trying to save it. Not to mention other problems they can (and often do) create.
Hope this helps.

I have found this too, although YMMV.
I use Llama (Location Aware Mobile App) to turn things of and on when I move about. I seems to work very well mostly:
1. Got rid of useless apps, and kill all listeners on new apps so they do not pop up (require root)
2. When at home or work, WiFi is on but sleeping when screen is off (this is the one that fails most often - need to monitor), data is off (to prevent use when WiFi is sleeping).
3. When out and about, data is on, sync is off (to save mobile data & battery).
Like this I can get very flat battery level graphs when the phone is asleep, which is what I want.
When the phone is awake, the only thing you can do is turn the screen auto orientation off (I use Llama to turn it on for certain apps), and keep the brightness down, and use dark themes for everything, really. Turn WiFi off when not using it would also help.
I just wish they had made the battery larger & thinner (as someone else said) so that a thicker battery could have been more effective still, like triple the capacity
Try disabling GPS, wifi and data connections when not in use to save battery. Also you could flash the latest abyssnote kernel. It has absolutely amazing battery life.
Ok going to try and start a conversation here to get feedback from everyone on what you guys do to get the most out of your battery. I see alot of people always asking what kernal is best for battery life and some people seem to have horrible battery life and some have exceptional battery life. I personally get decent battery life. Nothing super amazing but that comes down to the way I use my phone.
My current battery I'm using - Andida 2000mah battery
http://www.ebay.ca/itm/280843217453...X:IT&_trksid=p3984.m1497.l2649#ht_4497wt_1396
I also have - GTMax 3500mah battery
http://www.amazon.ca/GTMax-Extended-Battery-3500mAh-Microfiber/dp/B006VAP102/ref=pd_rhf_se_p_t_4
The Andida gives me generally a extra 2-3 hours more over the stock. I had to cycle the battery 4 times before I started seeing any real improvements. If I take these off the charger at 6:30am I can ussually make it to around 10pm without needing to charge.
The GTMax get me through a day (630am - midnight) with around 50% left.
Now keep in mind this is based on my usage habits, and when I'm at work my signal is horrible so it drains a bit harder for the 8 hours I'm at work.
I don't have LTE where I live or work, I do get LTE in areas close by but on a regular day I don't see it. With the bad signal at work I've started to switch to gsm only mode (phone was constantly switching from Edge to 3g/4g and wouldn't provide a stable connection most of the time). This seems to have helped my battery at work.
When I flash a new rom I always give it at least 2 good full battery cycles before judging the battery life on it.
Ok onto some apps. My first foray into getting better battery life started with wanting to control my data. I used Juice Defender to that but I found that having to wait for the data to turn back on was at some times taking way to long and even sometimes I would have to reboot to get it back. Tried a few others and had similar experiences. When it works its nice and I did see some gain from it but at the same time it seemed bloated and slow and I decided I like having my data on and readily available quickly. After some searching I found an awesome app...

I highly recommend reading up on this app and trying it out. If your seeing a big drain on you battery while the screen is off, it's probably because there is something that is keeping it from going into a deep sleep mode. This won't save you any battery just by installing it but with a little work it can make a pretty good difference.
Ok now this is where I'm looking for suggestions, are there apps that you find specifically run smoother or are lighter than their stock counterparts or rival apps that put less of a strain on the battery?
Instead of the stock messaging app I run Pansi SMS. It gives me a few extra options but I never really used the stock mms on ICS so I can only compare it to Handcent SMS and I think it is definitely lighter and a lil bit more battery friendly. It's not a huge difference but I try and squeeze everything I can w/o giving up functionality.
For a launcher I'm running apex right now, but for a lightweight launcher I'd recommend FTL. Runs really nice and smooth, nothing fancy about it, just fast and light.
Some apps sometimes can just be poorly coded and thus have a bad effect on battery life. Alot of people seem to feel the Facebook app is one such app that suffers from that. The app that gets the most recommendations as a replacement and being a bit easier on the battery is Friendcaster. I tend to agree with that, and would recommend trying it out.
I'd really like to hear about what everyone else does to try and squeeze out the most of their battery. Theres more stuff that I do, such as reducing the amount of things that are synced to only the stuff I actually want, default settings just sync everything and I don't feel I need to sync my contacts on a daily basis as I rarely change them around. So share your tips, experiences good and bad with apps in regards to your battery, and if theres enough feedback I'll try and re-organize this into a bit better structure.
I personally always leave data off. WiFi is on a lot. I wrote this:http://forum.xda-developers.com/showthread.php?t=1631831
I am very please to get a day and a half with the extended battery. Generally I am always texting,also.

Right here, this is the key. I have data off all the time. I only turn it on when I need to look something up or browse. IMO auto updates really kill the battery and aren't worth leaving your data on all the time. I'm on wifi a lot as well. Currently I'm on DarkRaider and I'm ending the day with around 30-40%, great improvement over stock.
It seems that with every new handset that comes out this is one of the hottest topics but the parameters all always the same with regard to battery life.
The 3 biggest things that drain our batteries are Display Usage, Data Connection & Radio Cell Connection. These are listed in order of current used. Of the 3 we can have some control over the 1st 2. Lower screen brightness and disconnect data when not needed and use wifi when possible. While wifi does use a good amount of current it's not as much as mobile data. The last one, Radio Cell Connection, we have very little control over. It's also the reason we see people having great differences in battery life. The further the phone is from the tower it's connected to the more juice it needs to make a good connection. So other than leaving the phone in airplane mode or planning your life around where towers are, neither of which are very practical, there is not much we can do there.
To get the best all around life from Li-ion batteries do not fully discharge them very often and also don't keep them plugged in after they're fully charged. It's best to recharge them when they get down to 20-30% and unplug them after they're charged. They also don't need to be fully charged every time, they have no memory. If your on the go and can only leave it plugged in for a short period of time that's fine. Also if you have more than one battery and your not going to use the 2nd one for a while don't store it at full charge. drop it down to 50-60% before pulling it out.
I'll update this post when I get home tonight with more info and links. Hope it helps.

I always make sure my auto updates are off. WiFi isn't an option for me when I'm working. How do you manage your data connection? Do you manually turn it on and off or use an app? I never really tried manually turning the mobile data on/off, just found with apps like JD that it sometimes took way too long to establish a connection. I always shut off my wifi when I leave for work. I know with ICS the widget toggles for gps don't work, they take you to the settings to turn it off, is there one for mobile data?

With my 3500mah battery I don't really worry about turning anything off. That thing is great. Made a bumper case for it but I miss having a real case on it so I picked up the 2000mah andida battery so I could get a few more hours on some days. If someone ever made a real case for those big batteries i'd use it all the time.

Try 2x Battery from the store. It will shut off data as soon as the the phone sleeps, it reconnects at screen on after unlock almost instantly. It also allows you to white list apps, like Pandora. The free version only allows 1 app though.

The DarkRaider ROM I am using has a nice extended settings menu in the notification bar with a data toggle. I also have a nice widget from switchpro widgets where I can customize what kinds of things I want to be able to toggle from my homescreen. Currently I have data/wifi/vibrate-silent/gps. Doesn't take long at all when I toggle the data on/off, it's pretty much instant.

I use the 2X Battery app. When the phone goes to sleep, the app turns off the data radio. I can still get calls and text messages. I don't have a need for push notification of e-mail, etc., so this saves me some battery usage. Of course, if e-mail and other app notifications are important, this app will help only if you are willing to wait until you wake up the phone.
Here's what I do. I'm on the stock HTC battery.
I SetCPU screen off to 192/192 ondemand, in call to 810/192 ondemand, and regular use to 810/192 ondemand.
I listen to about 2 hours of music a day, have 3 GMail accounts on autosync, a Facebook account on hourly autosync and HTC Weather on hourly sync. Automatic brightness. Roughly 1.5 hours of cumulative web-browsing, no apps/games used.
I never use WiFi and I don't live in an LTE area.
I typically end the day (19-21 hours unplugged) with ~40% remaining.
Now I am not sure if living in area with LTE is a bless or curse....
I would unplug around 7am everyday, and by the time I get home (around 6pm) I would always in red mode (meaning, it is either 14% or under). Using the Holics-0.6 with the kernel that came with it, battery seems to die fast. Even when I am on the stock ICS before this, seems LTE would just bleed this baby to death....
Reading other comments, might as well start looking for a bigger battery....
It actually seems like I'm getting better battery since LTE came to my town. I'm on dark raider using kozmick's rc1 kernel and it's even better now. Try turning off vibration feedback...I think it's located in the sounds menu in settings. You can also try using automatic brightness or even just setting it to stay at 50% or lower. The screen is a battery hog. There's a stickied thread somewhere on here that has other things you can try too.

Really is a shame that we have to disable or ease everything back so much to get through the day on a battery. Anyhow, I have a Velocity (which comes out of the box with the processor running at 1500) on Dark Raider. Therefore I use SetCPU to throttle the beast back, depending upon the circumstances. It only is allowed to run at 1500 when on charge and down to 400 when battery below 25 percent. I also use 2X Battery to take care of the netowrk and Wi-Fi and have purchased the andida battery for extended life. I also have JD installed, however it is rarely used - reason is that I am in agreeance with "citsong" that it takes too long to establish connections, even causing me general connection issues from time to time. So for around $25 AUD you can get through the day on a battery with moderate use and reasonable performance. I have not tried the extended battery pack, though I will probably get one of those as well...not sure which are the best???
I personally don't like the vibrate response thing, so I turn that off right out of the box, also, auto brightness is another that I set. When I go in the battery tab to see what is bleeding it to death, and most of it would be the display....
Though, vivid seem to have a smaller battery compared to other phones of similar functions and/or size, so that might be the reason I am not really seeing a very good battery life?

Actually there are only a couple phones that have a larger battery...
The galaxy note and the atrix are the ones that come to mind...
And the note has a larger screen and Samsung's rediculious samoled screen which eats battery like potato chips...

My solution was to get a larger battery (2100mAh, the largest one with stock format) and using juice defender to control my Data Connection. I am getting about 60% more using time on a normal usage whan before!
I actually have both Motorola Atrix 2 and HTC Vivid. However, my Atrix 2 would last about two days between charges, which is kind of weird. I have my personal account and company account on that phone (personal is to activate the google stuff), so it eats up data twice as fast, yet it is almost twice as long battery life.
And to update a little bit from my post before, it seems I am getting better battery life now, after 4-5 days of flashing the new ROM, let's hope it is true....or I am just going to go hunt for a bigger battery

Actually, the Samsung Galaxy Note is way bigger than either Atrix or Vivid, so with a bigger body, I would assume that a bigger battery is possible. But if you look at current phones, I rarely see batteries that are above, say, 1800mAh, let alone 2000mAh and above, stock of course.

Could you share the details on the battery?
Andida batteies are easily found on Ebay, but beware of Chinese fakes!! I got mine from a seller in Canada, all good.
I get good battery life by turning off data while I'm working . 70% with 8hrs unplugged

Hello mates,
battery drain is a big issue so i´m looking up different things to save some battery. does someone of you have experience with Juice Defender especially in addition with some configuration like mine (see above, PA & Kowalski) or similar?
I wonder about maybe kowalski kernel and Juice Defender "dont´t like each other" cause both of em change wifi behaviour and things like that.
I´m also thankfull for general meanings about juice defender if you want to tell me
Thanks in advance
(Yes I used search and yes i looked up some comments on playstore )
For how long do you want your battery to last my friend? With PA and Kowalski kernel my phone can last 3 days rofl.
Remember: A smartphone isn't supposed to last more than 24 hours if its being used.
as long as possible
I´m just trying to get some information weather this combination is usefull or not I know this phone can go for up to 3 days but with whatsapp, facebook messenger and some sound stuff the device goes down if you use it - and thats what I do
My question is simple, does it make any sense to use Juice Defender in addition to pa/kowalski and has someone done this before to give some estimation about it? (percentage compare would be nice, otherwise give me what ever you got )
Idle time is very nice on this build, even without juice defender and i think JD can´t do much about battery drain when fiddling around with the phone all the time, right?
Juice Defender only does things while your screen is off. Basically it turns data off then switches it on periodically for data sync. For me it's a noticeable improvement and worth trying if you don't mind your emails coming in a bit later.
Sent from my LG-P990 using xda app-developers app
the key to make sure your battery lasts long is making sure the cpu enters deep sleep if the phone is in standyby.
apps and widgets can and will prevent the cpu from entering it most of the time. so yeah the more stuff you install, the more widgets that require sync you use, will lessen batterytime. uninstall stuff you don't really need and you will be fine.
you can also use a tool such as cpuspy - https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy - to check how much time the cpu spends in each state.
It is also important to know what is causing the phone to wake up to check betterbatterystats app. Partial Wakelock and Alarms section, you can see what causes the phone to wake up hence using more batteruy.

No it doesn't. JD and kowalski are not compatible. I tried to use JD and wierd stuff started to happen. If you are on the latest [email protected] kernel, reduce the wifi transmission power to a level that suits you and try enabling PSP mode (see if it works with your modem).
juice defender is very useless!
i used JD over 1 month. it is really useless, my battery power was the same
I use it to:
-turn 3g off when connected to wifi
-turn off wifi when not connected to any network and turn it on automatically based on location
if you have problems with your battery, try to change the router if you can. I have a router that even if the mobile's mode is PSP, CAM, or otherwise, my battery runs out in less than 8 hours. Using another router, the battery life is about 50 hours with the same usage and programs.
You could also go for a better battery from a third party manufacturer. (Higher mAh-rating).
Personally, I don't use JD anymore. It proved incompatible to most of the roms I use.
