Hey,
I flashed lighting rom yesterday and was my first custom rom I have ever experienced. I love it, however battery life is worse than stock rom and I have done a recalibration of the battery. Is there something im not doing because I was lead to assume that my battery life would improve.
If there is something I am not doing, please enlighten me.
Thanks

From my experience a custom rom uses power pretty much the same as stock but once you root the phone you can freeze processes which then save the battery.
On stock I was getting screen on time of about 4.25 hours but now on villain rom I got just over 5 and still had 22% battery left.
I use ant tek app manager to freeze the processes.
I am sure people are going disagree with me here but I really think people are expecting a little too much out of this liddle-o-battery, if your phone is running at 1.2 all the time then its gonna suk-da-juice. I don't pick ROMS based on its battery performance as most now have battery optimisations cooked in as soon as they are found anyway. I just make sure I have some practical SETCPU profiles set to keep those megahertz at bay but also charge my Phone at work so it don't cost diddly anyway.
I also have a spare batter just in case
When the phone turns on, the camera makes a noise like it is coming on, is this normal? If not this could be it, however I have also noticed that the drain is absolutely massive when the screen is on (almost 10% in 20min)

To have ANY idea about whats going on with your phone post screenshots of settings > about phone > battery.
Of both the graph and of the list of %'s
Also what rom/kernel/modem
Only thing which is suspicious is that display is a lot higher than normal, possibly due to the crt bug where auto brightness is not very good, have now set it to manual.

Not a clue, without screenshots I cant know how you are using your phone etc
Fair enough, I may see how my use is tomorrow, I have installed juice defender so hopefully that will help things, I really like this ROM
I flashed litening rom 2.0 then cwm flash update 2.1 + 2.2 coming from stock rom noticed a battery life increase of about 50%.
Hi,
I would like to gather some general thoughts about SK17i's battery life.
I got mine about 8 days ago, everything is good, but the battery life is really disappointing.
In a typical work day I have
- wifi - off
- bluetooth - on during driving, that amount to about 1.5 hours
- mobile network data enabled
- probably 1 hour on phone call, max
- email checked every 30min interval
- browsing - maybe 45min, max
- no task killer software installed
- rooted, build number 368
I unplugged the phone from charger at 7.30am, and now is 6.00pm, 11hours later, the batt is at 20%, about to start giving warning message already.
Is this the typical batt hour you guys get?
one more thing, mine is an Indonesia set so it comes with host of program that I cant use in Malaysia. I have uninstalled most of them, except this MoxierPro which I cant seem to get rid of. I also noticed the program "Games by pop cap" seems to be running actively in the background even though I never start it.
hope to get more input on this.
thanks

yeah its really disappointed but in my mini pro its gave me minimum 24 hours with all time edge+sync+50% brightness. not rooted. stock settings. you know one day i got 4 hours on 100% stats. will upload screenshot soon.
i think u didn't followed up intial instrucitons for battery life like first few days atleast 4 days keep it discharge 100%-4-5% even let it off and then charge again to 0%-100% again dischage same manner, do it atleast 4 times (means 4 days) but before that u need to formate completely and try again. hopes it helps you.
well after coming from x10 mini pro this mini pro really next to awesome. i love it too much. just some boltware apps need to remove. need some games if any have plz tell me.
I think some of the stock app killing the battery, plus the data connection is the most powerful battery drainer. Anyway, first get rooted and remove some of mind blowing stock app. If u can minimize the data connection and use wifi instead of it, that can help improve battery life. My mini pro lasts about 1 day 10hours with minimal data connection but always witb wifi turned on.

on x10, it's been the same. after deleting some crap, the standy time increased from 2 days -> 8 days. especially playnow, trackid, timeshift & facebook including their extensings and plugins are draining the battery a lot.
i suggest to have look in this 2 threads and check, whats "save to remove"

additional there is a very good and simply to setup app you could try:
GREEN POWER - (availible as free and paid version)
http://www.appbrain.com/app/green-power-free-battery-saver/org.gpo.greenpower
Yup I think that some of the stock app is the cause of massive decrease of battery life at night, or during idle. But I just dont know what apps that cause this.
I really want to remove it asap

well i also want to remove, but by unlocking bootloader, i dont want to void the warranty also some features like xperia inside facebook, some camra function also may be stops to work so just waitng if any one root it without unlocking the bootloader. just like xperia x10 mini pro with superone click.
I am trying out Green power, seems to work well as it does not kill app but work from another angle: instead of always on data connection, I set it to turn on every 30 min using green power... so far it looks good.

well when its rooted then try to do a battery calibration
does it also have the BST-38 like the x10 mini pro?
You have to mention that because of the small design you can not expect that they implemented a more awesome battery that is small and has the same capacity like a battery of a large phone like the htc ones. otherwise such a awesome battery would have cost much more and would have made the price much more expensive.
As also the x10 mini pro has a lifetime of about one day I suggest it's the same here
Try turning of G3 and only use G2 if possible. otherwise we should wait until they ported cm7 to the mini pro where you can do this.
Nope, EP500 - 1200mAh, somewhat better talktime is promised in the specifications (5.5 hours) compared to old Mini Pro. But the device is still fresh, some customizations should improve battery life
Is there any high performance EP500 battery on market? like 2000mAh maybe?

Perhaps give time to cycle charge the battery several times (discharge fully, charge fully) so it will run optimal. The bloatware and the apps that keeps running on the background, uninstall them as they seem to be uninstallable. For the Popcap games, only way you can get rid of that is to have root and uninstall it. Since you mentioned you're rooted, take that useless crap out.
My unit is about to get a week old but I have very light usage and looks to me it can last best 3 days, so with normal usage will be definitely less than 2 days, which is like your experience. Anyway, the full cycles I am still trying to do and squeeze out what the EP500 can muster.
This is the best choice I can find on an alternative battery
Code:
http://cgi.ebay.com/130561150352
Looks like has double the capacity, which I believe should at least provide more juice. Planning to buy, but we better see what the fully optimal EP500 can do first.
Also, I'd like to share that I use SetCPU to downclock the CPU when idle to 122.88Mhz. When the phone not rooted, the lowest clock speed is ~245Mhz. In general our phones are more idle/standby than in use, so half the clock speed reduction will be good for the battery. As a sidenote, I wonder why Xperia models are like this (lowest stock clock speeds ~245Mhz), whilst Samsung ones go as low as 100Mhz.

with little to moderate use i can last almost the whole day. with moderate to heavy use forget about it, always bring a charger everywhere i go. i love the compact qwerty phone and speed but the battery is getting to me.

Youre just like me. I just want to root my phone easily using superone click too
Sent from my SK17i using XDA App
I was on the same boat but you just need a bit of confidence. The SuperOneClick even the latest one will not work because the exploit is patched on the stock firmware. That's the reason why bootloader need be unlocked so you can flash the insecure boot.img kernel (opens the exploit), which will enable the SuperOneClick to root the phone.
If you're bothered about the unlock bootloader, that can easily be relocked again following the same process, and you're back to stock.
yes i am trying to understand the rooting process to uninstall apps that is killing the 1200 battery.
you can force stop it but once you use the app again you have to force stop it again, and that can get old quick.

that's the way android works. when you start an app it will remain there unless its programmed to terminate on quit or disable (ie. juicedefender) or have an exit option (ie. opera mobile). they say it has intelligent process management which keeps things in RAM so its instant when you relaunch, and if it needs the memory it will kill useless or sleeping processes.
there's this program "autostarts" (needs root) which you can set to disable apps to start on triggers (ie. after phone startup, or when connectivity state changes), and i use that to ensure that apps that i rarely use but still need in the phone, do not start unless i start them, thereby i save RAM. for instance, i disable TitaniumBackup, because there's no point its running unless i need to backup/restore apps.
I have a disabled data, the 23 hours off wifi, bluetooth every 2 days one hour, the screen brightness to 50%, and the unchecked bravia engine, 12 hours. Generic rom installed, uninstalled all possible programs.
The battery lasts very little.
to see if we can CM7, sure but the battery lasts.
Thank you
I'm a long time lurker, first time poster, so please...go easy on me as I'm still trying to figure out the lingo and what not!
Anyhow, I just recently installed V6 and everything is absolutely great - except my battery goes down faster than <insert whatever reference you want here..hockey goalie, boxing, sexual>
I initially tried flashing over V5 and that's when the issue started - V5 was fine the way it was, but was starting to eat up the battery a little quicker - maybe due to a couple of new apps installed? did a full wipe and reinstalled v6 and am experiencing the same issue
I don't know if it's a problem with my actual battery or what...anyone have any suggestions?
Fully charge the battery until the green charged light goes off then reboot into XRecovery and wipe your battery stats.

Alternatively, there's the battery calibration app.
Alternatively, build your own stock ROM. Wolfs ROM has IMHO too many uneccesary tweaks that drain the battery... although his performance ROM has awesome battery (I'm using it right now)... lol I dunno why..

Well its tough to explain u, but use set cpu and reduce the maximum processing speed to 384. The battery will be consumed to the lowest. I have done the same. And my x10 works for min 1.5 day.

Not sure if my problem is the same but my phone WB v6 (even on v5) will turn off when used heavily i guess (less than 5min video games seem to be ok but other apps will do it randomly). but the battery will say like 65% whatever it should be from the use so far after a reboot most of the time i have then same % as before the umm crash but sometimes it shows 25% and turns off then if i leave it for a bet i get back to the higher % but will still crash with a little app use. Frustrating as i LOVE the ROM!
So far no crash during phone calls. But the crashes are no rhyme or reason. I have tried calibrating and full flash but it came back.
(would have posted in the ROM thread but i have too few postes and this seemed a better place)
Hung Wei Lo: which version are you using? Try lowering min frequency, adjust settings (like brightness). I'm on v6 with Freekernel and I get 2-3 days on a full charge. Maybe an app is preventing your phone from entering deep sleep.
Rabbit Stew: are you overclocking? Try a full wipe including battery stats, then installing v6s. The stock version should be the most stable.
Here's two methods that work for me.
To me the battery calibration app, is USELESS, no offence to the developer.
1. Wiping battery stats: http://forum.xda-developers.com/showthread.php?t=943626
or
2. Optimizing battery with just a charger and phone: http://forum.xda-developers.com/showthread.php?t=1071885
Don't go anymore then 5 tries.
I figured I'd give an update on this..
Things had magically sorted themselves out - battery life got better and better each day, though not to the point most of you are getting (I'm talking MAYBE 14 hours of minimal usage - the odd facebook check, random text message etc)
As suggested, I've set the min. frequency to the lowest possible, screen timeout is at like 30 seconds
As of the past couple of days, I've been getting half that...no new apps installed all the same settings...wifi is off, brightness is set to 25%, no gps usage all I have on is data. As an example, I charged her up and unplugged it with an hour to go before I was done at work. an hour ride on the subway doing nothing but listening to some tunes, and I'm down to 60%...in two hours
I'm at wits end here...according to cpu spy here are my most recent stats:
998 - 0:01:49 - 35%
576 - 0:00:-4 - 1%
384 - 0:00:03 - 3%
245 - 0:00:52 - 17%
deep sleep - 0:02:11 - 42%
thoughts (related to this issue)? suggestions? ideas?
is calibrating the battery will solve the phone randomly restart??
In my infinite wisdom, I'd have to seriously doubt it...did you do a fresh install?
heres a few screenshots from the last few days with various type of usage im just wondering if im seeing normal battery life
ive noticed that when im just texting for a bit or doing something else for a few min each percent seems to drop off pretty fast..i dont know if its because my last phone was in the 10 percent increments and im not use to it or if i have something draining my battery faster then it should
firstly this is what i have my brightness set to at all times dont know if its better to leave it this low or put it on auto..i dont like it to bright right now cause i have some eye issues
so the following 3 are with very light usage for the most part except for when i first woke up, sorry for the ringer toggle on the last didnt think there was a need to retake it
and these were taken earlier into the day but because it seemed like i was draining it faster and i would say this was moderate usage
if any other details are needed to really see if theres an issue please let me know and i will post
It looks fine for stock... Nothing out of the ordinary... Getting 13 hours and having 60 percent left is pretty good if you ask me... I have found that the phone will use the battery fast if I'm using it... But when it's idle it barely uses any battery which is fine with me...
Coming from a day one thunderbolt on 4g in its infancy where I would get 5 hours idle if I didn't use the phone... HTC has come a long way in 2 years

You have to remember that the screen is the biggest power draw. The more it runs teh more drained.
Also the more apps working in the background dont help. battery savers, loggers etc infact use more battery....

yea i think thats the lowest i can do on brightness without ruining the display all together at night when i use it in the dark alot and hit autobrightness it doesnt really change so thats really my sweet spot for light..other hours of the day i think auto would make it higher than what i have it set at
i disabled alot of apps today..i dont really have anything auto syncing only thing i have consistently going is push email
I've noticed that this phones battery lasts a long time as long as you are not playing games or watching videos. I have been browsing the Web and texting all day and I am still around 60%

Can you (or anyone else) figure out why the Kernel and Android system is using so much power?
Mine are both consistently around 21-23% battery usage, while the screen is doing 9-11% battery usage, with 3.5 hours screen on time.
Amazing screen!
If screen power usage is so low, the battery should be able to go for way longer than the 15-16 hours of usage I see.

My battery seems about the same, I think it's pretty normal.
I'm on liquid smooth nightly, the latest kit Kat one and I'm at 75% the first hour.. On Wi-Fi. The only thing I'm doing is restoring titanium back ups and installing apps. I'm using the badass governor, even though I don't know what it does, and have locations and Bluetooth turned off.
I'm coming from cyanogenmod because my battery was bad on that and I though a new rom after wiping everything would help my battery. I just made it worse. I wiped data and both caches too. The screen has been on the whole hour, but 75% is terrible. I used to go 30 plus hours easily on the same battery.
This phone is over 3 years old with the same battery so could that be the problem? Should I be using an official Samsung charger? O already tried the format option, that did nothing. What options can I change to get decent battery life again. Downgrade? Please help, posting on forums is my last resort, I read multiple posts about this problem and nothing worked for me.
1. If your battery is as old as your phone...then woah...you should probably get a new battery.
2. If you don't know how the governor "badass" works then you probably shouldn't use it. I don't know how it works either..it could be used for performance which would likely drain battery.
3. Use governors pegasusq, pegasusqplus, Zzmoove or on demand(tuned) as these tend to work well for battery.
4. I've heard battery on kitkat Roms tend not to be good?
5. Try a stock based ROM if your willing.
6. Install betterbatterystats to see if any apps are waking your phone when its in deep sleep and thus draining battery periodically.
7. Install greenify...and hibernate apps you don't need to be running in the background.
8. Profit. (maybe )
Hope this has helped

Yes, its battery timing is not good.
What is your battery like on stock roms? I've found that stock + a custom kernel works the best in terms of both battery life and stability.
Mostly sounds like the battery is just old as butt. I had a bum battery when I first got mine and luckily got a replacement for free. The new one has been working fine ever since (been a lot less than 3 years) but 3 years on one battery is pretty darn good if you ask me. OF course there could always be some sort of other problem but everyone's best guess says get a new batt. Hope it works out.
