[Q] Battery Life, Return Or Not?

First off, I am loving the phone. It is such a massive leap from the N1 I had been using. While I expected lower battery life, I did not expect to run through 70% of the battery in 4 hours with moderate usage.

I have heard of people getting far better battery life, and have tried the various methods, from charging to 100% then turning the phone off and charging again to 100%, using juice defender ultimate, and even resorting to factory resetting the phone. Still I can't get any kind of good life out of the battery. My question is should I try and get a full replacement for the phone or just the battery? I've only had it sinceblast Thursday, so I know AT&T will happily exchange it, but if yall think it's just the battery, I'd rather just replace that then the whole phone.

Have you found out what is using your battery?.. Even before I rooted and all the other stuff was getting at least 10hr.. now Im getting 24-28hours...
Are you running another ROM other than stock?

Didn't want to root if I needed to return anything, so I am running stock currently. Looking no app seems to be running away and draining all the battery. Everything looks the same as it did on my N1 in terms of what's draining the battery, which is what lead me to believe it's a bad battery possibly.

Yeah.. it very well could be.. mass produced items= bound to have some duds here and there..
Return it for another.. This is a great phone!!!

definitely return it.

Well if you do root than TPC's Rom is the best. It comes with kernel and the battery life is outstanding.

I was concerned with battery life at first as well. When I first got this thing I had to plug up 9 hours after I unplugged. So now I am near 30 days with it and the battery seems to have leveled out enough for me to be happy. I got 16 hours on it STOCK no ROOT the other day without plugging in, was at 10% when I finally plugged in. Yesterday I activated Juice Defender again after getting some questions answered. I got 17 hours without a plug in and was still at 25%, so i probably could have gotten 20+ hours if I needed it.
So I am happy now 17+ hours is plenty long enough for me, I always plug in at bedtime anyway.

I'm wondering how many people who are reporting battery issues, if they have calibrated them. Charge your battery all the way, use the phone until the battery dies, then fully charge. This will give a more accurate reading as far percentage used.

There is a new ROM Piret RC1, the battery life is amazing, it has a different Kernel as the one with TPC has it';s problems.
RC1 is clean fast and in 2 hours I used up 4%. Then turned every possible service on used it up like crazy to drain the battery, installing/backing up/ flashing new rom and it took 2 hours with heavy usage to drain from 17%. Just to compare last night I had a TPC ROM and was on WhatsApp for about an Hour and battery went from 85 to 34 %.
Re: Returning the phone.
First once you root you can the same way unroot, make sure first you install a stock ROM.
My friends have the same problem, one with this phone, and others with android phones in general, don;t waist your time returnig. To be safe you also have a year to send it to Samsung to get fixed if there is something wrong with it.
Basically, running apps will kill battery, location services kills it the most, sync not so much, heavy use of data does to (I have LTE plan). Use power saver to start at 70%, configure it right, use the CPU app to manage the speed ondemand.
Most important don't frick out, the andoid phones are like that, the major difference is that Iphone does maybe 20% of what android phone does in standby and many things are not available on Iphone, so the battery is better. You will not get more then a day of use on android if you use it to your benefit. 28H is mostly standby, no sync, no internet usage, just moderate. I used to use Iphone heavy and battery would not last a day.
Get a good data plan, don;t use WI-Fi unless u have too, when syncing with the car plug it in the charger, spend extra $10 get a Samsung cable from them, don;t go for cheap 10 dollar once or even 1 dollar once from China, they are very slow to charge. My cable from the box take 1.5 H to charge to 100.
Hope it helps, please don;t quote me on anything, this is purely based on research and one week usage and trying different things, it's strictly my opinion, don;t expect your phone to last like they use too, it's 21st century and techno in it is overwhelming and needs power. Keep the phone have two cables and enjoy!

This is my first smart phone, after 20 plus years of having cel phones. I try to read before posting any questions.

good habit to get into thanks for that....the search button is your friend.

I have been reading on the battery issues, long before I posted. I have done everything from calibrating, to using juice defender ultimate, to doing a ritualistic dance to try and coax more battery life out of this phone. Still with nothing but 2 phone calls and one quick spelling look up, dead within 8 1/2 hours.
I just got my extra battery and charger from samsung in today, already fully charged up this battery and will see what it can do for a few days. I'm hoping my problems are just a random bad battery. I also factory restored and am running bare minimum on apps just to try and remove all variables. If there still is a problem I will exhange it for another one next week. I just hope they still have some white ones in stock

My battery went completely dead too. I returned mine. Black model though. New one is doing okay so far. Better since it doesn't report 100% battery until a reboot...

Finally went and exchanged it last night. So far I have gotten 9 hours of battery life and am only down to 70%. Better than before, but the vertical lines on the screen are worse on this one than the last.

I have almost the opposite "problem." Not that I'd call it a problem just yet. I had my phone running from about 10am till 1am yesterday. I went to bed and plugged the charger in and it instantly said "battery charged 100%. Remove charger." 15 hours with no drain at all? Granted, I didn't do much with it yesterday but send about 20 text messages.

Going on 32 hours+ battery life and no vertical lines.. bought it when it came out Nov6....

30% in 9 hr's? you need to see what is killing your battery... unless you play games or on the net all day.. that is not good at all..
I lose about 1% an hour..

I don't know what you smoking man but i tried his rom and never had issues. Let me tell you I Have ORD so my suggestion will be based on my usage rather than prediction. I have tried most of the themed/tweaked roms. Don't like stock rom.

Considering I used to be lucky to get 10% drain an hour on standby before, the 3% our so i'm losing an hour now is awesome. And in those 9 hours I checked google reader and played some levels of Trial Extreme 2.

Three days (66 hours) on one charge!

I bought a used G2x in December 2011 and had okay battery life on the stock ROM. In January I started modding the phone with the Hell Phoenix and later Hellfire Sandwich ROMs. One day my phone started getting really hot and from that point on my battery life got worse and worse until it would only last a few hours. I ordered an 3500mAh extended battery from eBay, but it only increased the stamina of the phone to about 5 hours.
Since I never got a receipt from the previous user I had no warranty. However, I called LG and agreed to have the phone repaired for a fee that would not exceed $100 - they said it would cost between $40 and $100.
Fast forward 10 days and I received my phone back with a "replaced chipset" as it said on the note. And LG was nice enough to not charge me for the repair - kudos to LG!
I noticed that the phone was not getting hot or even warm anymore so I charged the 3500mAh battery to see how long it would last.
Unplugging the phone from the charger Thursday morning just before 8AM I used the phone as usual (light/medium use, but everything except BT enabled) all day Thursday, Friday and Saturday until the phone finally died Sunday morning at 2AM. Yes, that's 66 hours!!!
I'm still flabbergasted that this was possible, especially because I used the phone as usual and made several calls each day.
I'll try to attach a screenshot of the battery use. It was made at the time I went to bed Saturday night so it's not the full 66 hours.
Has anyone else ever gotten results like this or even higher?
Android version: Stock 2.3.3
Kernel: 2.6.32.9
Battery: eBay item 180721306295 from "bridge_wireless" $9 including shipping

Get Juice Defender Plus, it'll toggle your wifi automatically and save even more battery life.
Light usage (sending maybe a hundred texts and a couple web pages loaded) will easily get me through the weekend.
Using Faux DS Kernel and stock battery.

I tried Juice Defender Plus and Faux DS kernel in January but never got any amazing results, but maybe my phone wasn't that healthy back then. Also, I didn't do anything to save battery life during the 66 hour test other than setting the screen brightness to "Auto". I also made several phone calls - as far as I remember it was about one hour and thirty minutes in total.
This really makes me wonder how long I can get in "power-saver" mode (dim, wifi off, 2G, Juice Defender, Faux DS) with the 3500mAh battery. Has anyone tried this?

I would be happy with 12 hours of light/normal use.
Im using the trinity kernel. SetCPU,Juice defender, auto dim screen, Wefi plus,
the only thing that syncs often is facebook on the hour.
and I cant make it 8 hours on one charge.
I rarely use the phone for calls mostly use text for work and friends.
facebook & web through out the day. if i let the phone sit and dont touch it the battery will last all day
I know I am no "light" user. I bought the damn phone to USE it. but I wouldn't say I am always a heavy user. I dont expect to stream for 8 hours but it would be nice If i could listen to the stern show,check Email,facebook,Web & text and only need to charge once halfway through the day then again overnight

Most I've gotten was like 22 hours! -___-

I am definitely a HEAVY user and get around 16-18 hours on a charge. Constantly have Wi-Fi on, sometimes mobile data, gaming such as Temple Run and Angry Birds, and atleast half the time listening to music through PowerAmp. Constant texting, and maybe about 20-30 minutes of calling.
Also, when your cell standby surpasses your display usage, it shows you aren't really using your phone.

I'm not sure what you're trying to get at . As I said I used the phone as I normally do without any "battery saver" methods in place. I never claimed any heavy use during this test.

How fantastic - and thanks for the great constructive feedback! I love the warm feeling of knowing that the time I spend sharing my knowledge is appreciated without disbelief.
Really, I don't want to waste my time if you can't read. Just wanted to share my battery experience with stock 2.3.3, non-power saver configuration under normal phone use. And my idea of normal phone use is NOT just checking the time like you say. Compared to my experience when I originally got the phone I'm now getting way better battery life. I believe that the spread in battery performance is wide and far too many people settle with 4-6 hours of use before recharging with the reasoning that it's a dual-core phone and therefore swallows power as was it Gatorade. If I'm wrong and everyone knows that the G2X can go days on a charge then sorry that I brought it up.

Well when your display usage doesn't even show up, yet your cell standby and phone idle are at the top of the list, this means YOU ARENT USING YOUR PHONE. Any way you want to play this out, its not surprising that you get so much life out of your phone since its usually used as a fancy paperweight.
Maybe have your display usage on par with cell standby, then come show off amazing battery life.
Also, the 4-6 hours of life is most common on stock Froyo/GB. Not an issue anymore with custom roms.
Sent from my amazing G2x running EaglesBlood and Faux.

Guys, c'mon. You're not even talking about the same thing as each other. A debate is completely pointless.
theking_13 says you're not using your phone enough for the 66h to be that impressive.
PhilipCourtois says he wasn't bragging about how amazing his battery is, but just stating how much of an improvement it was over the stock experience.
Both of you are right. Philip is in fact not a very heavy user, so a longer life for a battery isn't completely surprising. However, phone idle accounts for 21%, whereas everything else accounts for 79%, which is by no means at all "a fancy paperweight". You can even see that the apps that were used account for 39% of the usage at that point, which is more than the cell standby. Furthermore, judging by the graph statistics, the phone was turned on relatively frequently.
Now for something on topic: I'd be interested in seeing someone do a proper test on a 3500mAh battery. Something along the lines of charging it up to 100%, leaving the screen on at 100%, settings both min and max CPU clock speeds to >1000MHz, and doing whatever else you would normally do on your phone in addition to that. Then posting a screenshot of how long that would last them. I predict somewhere along the lines of 9-12h, but it'd still be more informative than a lot of the reviews here. Not to say that the reviews here are unhelpful of bad, because they are very much so helpful.

Good point, but the app usage on GB is extremely inaccurate. I have had my phone on for 3 hours, 27% usage by cell standby, and I played Draw Something for two minutes, and it shows up as using 17% already? ICS graphs on the other hand, are more accurate.
Sent from my amazing G2x running EaglesBlood and Faux.

Hey, you said you get >16h and you're a heavy user. Now I'm not doubting that in any way, but I'm using the same ROM as you, as well as the ELP kernel, which not only is optimized for EB, but is also supposed to be a battery saving kernel. However I get probably around 12h on medium usage. I've tried the faux kernel, and it did give better battery life than the T15 Trinity kernel, but on ELP my device lasted longer (T15 < Faux OC/UV < ELP for me, in other words).
Anyway, my question is did that Anker battery give you far more life over your stock battery, or is your device just lucky when it comes to battery usage? An extra 50mAh is barely anything, but you did mention in another thread that it runs cooler. From personal experience, my phone battery drains faster when it's warmer, so maybe that's it?
I'm really just curious because I've been messing around with battery saving techniques/phone accessories these past few weeks, and I just seem stuck in that 10-14h range on medium (maybe even medium-light by your standards) usage.

My highest is 8 hours. WTF
Sent from my LG-P999 using XDA

How much do you use your phone in those <8 hours? I have moments when I don't touch my phone for hours, and generally I go down at about 2%/h when on standby. So if you ignored those, I'd probably be in the same boat as you.
For example, this is me today:
As you could probably tell, I haven't exactly used my phone a lot today, so I'm at 47% after 11h. However, I tested my battery this weekend by setting my screen brightness to 100%, screen timeout to never, and CPU min/max to 1100MHz/1100MHz. These were the results:
As you can see, my battery didn't even make it to 4h, so it really depends on how you use your phone.

You're right. I never wanted to start a debate - all I wanted was to shed light on the fact that battery life of the G2X can be fantastic - even on stock GB - with the simple upgrade to a 3500mAh, cheap ($9) battery. Before I had the chipset replaced, the phone did NOT last very long and from everything I read on the forums, crappy battery life should be expected if not flashing a custom ROM with battery saver kernel. I'm just saying that that's not true for every phone.

If by "stock experience" you mean the condition I bought the phone in - then yes. But by my standards, the phone is now in as close to a stock condition as you can get - all I did was put in the larger battery. It's running stock GB 2.3.3 with all the T-Mobile bloatware still on it, Google+ on, data sync on, WiFi, 4G etc. on and screen on auto. And I really doubt that LG put in a "special", fantastic chipset when I sent it in for a repair.
Anyway, it seems a real enlightening discussion is on the way once we really start comparing use versus battery life and see that our phones differ dramatically in this regard.

Well I'll tell you everything I did in a sec. But the battery helped maybe 20 minutes, but it is a new battery, so its going to get better results than one that is say 9 months. If it was a brand new LG battery, I'd get the same results.
Now onto what I've done to get this much. First of all, I use EaglesBlood rom and Faux's v0.48 kernel, CM Driver, not DS. I use Wi-Fi constantly, say for about 3-5 hours of the 16 hours that its used. For the most part, I have the network set to only connect to EDGE, not UMTS or HSPA. So 2G for most of the day. Then on the way home, I use 4G for around 30 minutes to an hour, and thats what kills my battery like there's no tomorrow.
Some other things I've done are replaced the Gallery app (supposedly uses battery all the time scanning for files) and use QuickPic instead. Replaced the stock Browser with Dolphin Browser and not only is it smoother, but it doesn't run in the background after I've closed it. Also, turned off logging for the SU app, turned off notifications for Facebook, Play Store, Words with Friends, Scramble with Friends, and auto synching for my Google accounts. Basically turned off background notifications for all apps except Pulse (news app) and Voxer (walkie talkie app).
Lastly, I have my CPU set to 216-816 MHz all the time, unless I play a game and whatnot. I notice no lag whatsoever while playing music and texting/on XDA/ browsing Pulse/etc. I undervolted -25mv across the board, even after what was already lowered through Faux's kernel. Ill post a screen shot so you know what they are. I found if I lowered them more, I'd get reboots sometimes when turning on Wi-fi.
If you have any questions, reply here or PM me. I'll be happy to help.

[Q] Battery Tips and Tricks

Hey good day guys, Just looking for some Battery life optimizations tips and tricks, my phone is used heavily as it is my work/personal/entertainment device, Right now Im getting around 12 hrs out of it. Anyone have any ideas to boost this?
Info:
SGH-I727R
Rooted Stock Rogers ICS 4.0.4
SetCPU (Powersaving)
JuiceDefender Ultimate (Aggressive)
Bloatware removed(with some non-essential services Frozen)

you seem to have covered the basics, you could also undervolt and keep your screen brightness low if its not a hassle.
you could try supercharger http://forum.xda-developers.com/showthread.php?t=991276 I have no clue how well it affects out phones never really had anything to compare it to.
If your a heavy user you could always consider getting either extended battery or spare batteries with a charger and just switch whenever you need.

Aside from getting extended battery, other things you can do is changing the kernel to a tweaked one such as this:
http://forum.xda-developers.com/showthread.php?t=1701189
You can set wifi/data to shut off while not in use (I use this one).
Some people get good battery life with SkyICS (Custom ROM) and I have actually have gotten 3 1/2 days of light/standby use from it which is pretty good.
I personally use CM9 with a custom kernel but with everything tweaked, brightness, undervolt, disconnect when not in use, no auto sync etc... I get about about 15-20hr light/mild use, I did manage 2 days with light/mild/standby use and maybe 1%/hr standby drain. :good:

you seem to have covered the basics, you could also undervolt and keep your screen brightness low if its not a hassle.
you could try supercharger http://forum.xda-developers.com/showthread.php?t=991276 I have no clue how well it affects out phones never really had anything to compare it to.
If your a heavy user you could always consider getting either extended battery or spare batteries with a charger and just switch whenever you need.

Aside from getting extended battery, other things you can do is changing the kernel to a tweaked one such as this:

I get like 17-20 hours with moderate use a few calls when running stock (including the various leaked stock ROMs)
When I flash a custom ROM, seemingly any custom ROM, My battery life falls to about 8-11 hours, pretty much half of what I had been getting. It's extremely noticeable, I can practically watch the numbers count down as I'm using it.
I know this is not normal. You can convince yourself 12 hours is great even with all the power saver stuff on, but our phones should be doing a lot more and we should be asking why they aren't.
Standby time is especially dismal in my current configuration. It loses just as much as when the phone is in use.

Search around, it's been answered before. Yesterday I got over 20 hours with almost 3 hours of screen time. I lose about 1% per hour when idle, roughly.

Or, better yet.. tell "us"
I've been pulling my hair out searching xda, other forums, google etc for answers to why i'm getting poor battery performance with a rom with virtually no use vrs 17+ hours on stock with moderate use.
I use juice defender, and nothing else and "cell standby" and "phone idle" are the two biggest issues killing my phone right now. 25% down in just 5 hours, and i've not used my phone for one thing except a quick 1 minute call - radio's are off except to check email once an hour. It's ridiculous.

Once search is working, this should help: http://forum.xda-developers.com/search.php?do=finduser&u=4394011

quick question, do u guys give custom roms a few charge cycles (aka days) before u judge battery life. The best I've ever gotten was 24 hours with 4 hours on screen time with gb based tpc v3, heavily customized. That being said the first two days I wuz getting less than 10 hours... just sayin
p.s. that wuz without the use of crap apps like juice defender

Nope.
This very issue was brought up in my last thread asking for help. I didn't know JD would be making things worse, or that it would take a few days for things to settle out.
Now that I know these things are normal, like getting 10 hours for a few days i feel a little better about the situation.

Nope, I flash a new nightly almost every day, and I still get 18-20 hours that day without a problem. If your phone isn't deep sleeping when idle, it's chewing battery, this is the most common battery drain problem that I've seen.

I have given it a few days in the past and for sure it makes a difference, but at this point I can tell right away if it's not working right. The battery life is literally like 30% of what it should be, I can just watch the numbers tick down.
The dead giveaway is that it loses battery as fast in idle as when it's in use. Which says wakelock problem like others have said, but I don't know how to fix it.
I've also noticed performance is worse in CM9 than in UCLE2/UCLF3, and that seems counter-intuitive, but there might be some performance tweaks in the TouchWiz ROM that CM isn't incorporating.

I'm using a stock 2.3.6 with some tweaks.
I froze all the bloatware and services I don't use, NFC/VPN for example.
I use faux123 .10m kernel and underclocked to 192Mhz/1.02Ghz and undervolted by 50mv - http://faux.androidro.ms/sky-kernel-010m.zip
Flashed Rogers radio for unlocked RIL - http://www.m-s-j.net/skyrocket/Radio_RIL__I727RUXKJ7.zip
Set it for only 4G and no LTE via *#2263#* and choosing WCDMA 1700Mhz
I haven't payed attention to my battery time/display on but it is definitely better than stock.
Also, if you use the Facebook app, that seems to be the biggest battery drain between it syncing contacts and always GPSing when you open it.

SetCPU profile for incall,screen off,temperature,and or battery level(increments of ten)
Also freeze or disable unused services that use cpu resources
Set your screen brightness lower
screen timeout to 15 secounds or 30
If youre really having a big issue try disabling background data although you shouldnt go that far.

I've used stock GB and ICS and have had great results by turning off LTE and also disabling WiFi during sleep. I can get nearly two days on regular use, browsing, phone calls, emails and MP3 playback.

So after 3 days of testing apps, applying a kernel, setting CPU and more,
(CPU ondemand, Governor: SmartassV2, Kernel Cymbaline 1.5)
I still only getting the same battery life as before about 12 hours, I don't understand how some people are reporting 20 hrs on a single charge with moderate usage. I looked over the wake lock apps and none seem to be stopping deep sleep, unless I have like the music player on. I don't know what else to do, any ideas?
besides addition batterys or extended batterys. And please try to be as detailed with apps/settings as possible to achieve the amazingly 20hr mark on moderate use.

Its pretty much subjective as to what people say, everyone will have their own definition of light use. When I say light use I mean, check facebook, twitter, instagram, tapatalk, boom done. Medium use for me would be like browsing the web and maybe playing a quick game of diamond blast lol. Heavy use for me would be playing a game for an hour+, using GPS, watching youtube/video/movies etc... So it will really depend on use. I've been playing around with custom kernels and usually look for ones that has UV or undervolting, downclocking is also good and using an efficient governor, some are good with efficiency and doesnt use more than it needs, say I play a streaming program like pandora and it sticks to 192mhz rather than blasting to 1.5ghz etc... So each tweak will add up.
I was driving yesterday for about 3hr with gps on and was browsing the web a lot on LTE and it drained my battery and got maybe 9hr used that day. On a regular day with "light/mild" use I can get 20hr light 15hr mild 9-12hr gaming/browsing all day. Browsing also eats power when you're in an LTE area as it drains a little bit more. So really it depends on how much time you put into tweaks and know what you're using.

Like this one for example, longest battery I had so far with very light use. Meaning I would only check for notifications and was barely on it for more than 10min at each time. Wifi was set to disconnect when it wasnt in use. And this was using an older version of SkyICS so no doubt its pretty good with battery life and doesn't drain a ton when on idle.
This was yesterdays pic, why was like 10%~/hr? I had GPS on the whole time and the radio was using LTE speeds so by the end of the afternoon/night I was already down to 5% battery life. And this is on CM9 with custom kernel but it was set to 192mhz/1.8ghz so yeah settings will make a big difference.

[FIX] Battery Drain Issue Solution

I was always having the problem of when I would turn my device off for the night when I turned it on in the morning I would have lost anywhere between 15% and 40% of my battery. The easiest solution (only if I remembered to) was to pull the battery every night after I turned the device off, if I remembered. Well this was an annoyance for both having the battery drain if I forgot and to have to remove the batter every night and then put it back in every morning. I know it seems like I am just complaining with that last statement but I just like to have a phone that just works.
Now, back to the problem. I was always running either a port of MIUI or a CyanogenMod Stable release with both 'stock' kernels or one of faux's for CyanogenMod or morfic's for MIUI (as they got along better for some odd reason). Well, no matter the combination of kernel type (OC, UV, or Stock) I always had the battery drain problem and stability issues (depending). Then when the new baseband was released I installed it after I found out that the CyanogenMod RC3 supported the new baseband to see if that would fix the problem, just it still didn't work even with different kernels.
I was starting to get fed up with these issues so I decided to try one last thing: I used the LG support tool and went back to completely stock! I did root it with SuperOneClick though so I could use all the apps that I was using before (Titanium Backup to restore all of them). I have been running my phone like this for two weeks now and have never once had the battery drain problem. And what is even better is I am getting an average of 40 hours of use out of one charge in and out of WiFi with WiFi calling and 4G when not on WiFi (mind you I am not a really heavy user). I hope this helps!
Well, I know this is a long post but I figured some back story would be good for those to see if you have had the same issues to be able to see if this solution could work for you too. Please click Thanks if this helped you.

So, It sounds like the custom roms issues then. I had the same issues and did evevy thing you have done except using stock rom.

Could you post a picture of your battery usage?

Might have to try that I don't know how long I could stay stock tho

I've had the toughest time with this phone. I originally bought it from a guy off craigslist to replace my wife's MyTouch 3G. It was completely stock when I bought it and after messing around with it for a few hours I decided the phone seemed to be in good working condition. I have plenty of experience rooting/flashing the MyTouch 3G and my Samsung Vibrant and I have never had any problems. So I read around here for the LG G2x and went ahead and rooted it/ flashed ROM and soon after I updated to the newest baseband. I started noticing that the battery drained really quickly, to the point that my wife couldn't use her phone for long. She would play Scramble with Friends for maybe an hour and the phone would be dead. I tried flashing other ROMs to no avail. I went back to stock ROM and unrooted it but the battery still was terrible.
I started thinking maybe it is the battery, so I bought a 3500mAh battery off Amazon, but no luck. I have searched and read many many threads about this phone trying to fix this issue. I've tried downgrading the baseband but was never able to get it done. I'm sorta stumped on what to do next. The phone seems to hold a charge magnificently if nobody uses it lol. I charged the 3500mAh battery to 100% and then I left the phone for 24 hours and it was still at 99%, but as soon as you use the phone it dies quickly. My wife already gave up on the phone and I ended up getting her a Samsung Blaze which has been fantastic. Now I have to fix this phone and sell it or use it myself, but I don't know what to do. Any ideas or detailed instructions? I'm tired of searching for help on this issue, was about to make a new thread about this when I saw your thread.

Stock has good battery life but I actually got the best on EB 2.3.7. Decided I would try an ICS ROM again but it seems they all burn up battery like crazy and there's no way (that I've seen at least) to turn off background data which I've noticed is the biggest culprit as it drains the battery fairly quickly when the phone is idle.

This ROM by BuROM is really good. It's only slightly modded Stock and gets great battery life because of that.
http://forum.xda-developers.com/showthread.php?t=1661610
Another problem may be that you are using different services on the stock kernel. If the battery is draining really fast when there is a network connection then something is probably constantly on the network. I always (meaning sometimes) test ROMs on airplane mode overnight, on WiFi only and on 4G only just to see what their drain times are. The stock kernel is pretty good but the newer CM7 kernels are fine too. I only get about a 1 hour difference after 2 days on a ROM. For some ROMS the first day is horrible as the software is doing all sorts of things. After about 2-3 resets and as many fix permissions it usually settles down into a similar battery drain to the stock kernel.
@Kingfanpaul: If that G2X drains the battery with only BuROM installed and gapps (without any other apps) then it's a hardware problem. I'd NVflash stock, check APN settings and then run it for a day to see what happens.

I have the EXACT same problem. I've already gone through 5 different batteries but still cant manage to get my G2x to last more than 8 hours and thats best case scenario with VERY lite use. Your post is making me think it's these custom roms. Going to try stock 2.3.4 and hopefully I get the same result as you.

What is your screen on time? I'm on latest stock CM7 with stock CM kernel and I get 2+ of screen on time easily with a 1year+ old battery. Battery depends on how you use your phone too. mAh and kernel can only do so much.

Something odd that I have noticed is that while my phone has more consistent battery life, some of the issues that I have had with this phone are due to a bad device. My phone tends to go crazy every so often and just burn through the battery to the point of over heating. From what I can tell this is just a problem at the hardware level with my device, so while sometimes going to back to stock does help the battery if it keeps up it may be more than just the ROM.

Try to turn mobile data off / wifi off ? I have similar problem with battery drain... Right now, at deep sleep the phone sometimes works as expected : 4-7mAh, but sometimes it drains way higher : 20-50mAh.

Not sure my on screen time. I know its definitely less than an hour. I'm averaging about 5 to 6 hours of use. About 20% drain per hour on light/medium use and 10% a hour when idle.

I used to have this issue on my old g2x even on stock roms and it seemed hopeless no matter what I did it came back. Then that phone got run over by a car. The one I have now doesn't have this issue at all on any rom or kernel....well.. almost. Some kernels are sorta battery hungry, but nothing like what I had before.

So you think it just may be a hardware issue? Bad phone?
Sent from my LG-P999 using xda app-developers app

I guess it's possible. Have you tried a new battery?
Edit: o. I see lol
The things I tried were the nullifier and the other wipe tool who's name escapes me... nvflash based. By mansa_noob. And the day it got ran over I had flashed buru's rom and I was hoping that took care of it but I didn't get the chance to find out.

[Q] Is the battery life really THIS low?

Hey guys.. I'm new here and I plan to stick around..
I just bought a used (for 1 year) Galaxy SL from my friend at a throwaway price. It's in superb condition and everything. Its been a few days, and here's the stuff I've done till now -
1. Immediately upgraded to DDLF2 (India) using Kies. Found some bugs after upgrade. For example, the promised "Video Snapshot" feature wasn't there. Also, the phone rebooted randomly many times in the day and battery ran out quickly (after about 3-4 hrs of moderate usage)
2. Next day, after noticing the weirdness, I decided to flash a custom rom. I heard from many, many sources that Frankenstain Mod and the Bam kernel, along with DDLF2, are the perfect combination for stable performance, nice looks and great battery life. So, following some instructions, I rooted my phone and flashed the rom and kernel. I was (am) REALLY impressed with the final result. I went ahead and installed apps, played games, showed off etc etc..
But sadly, the battery problem still remains. Of course, it has definitely improved a little, but the maximum it can stand till now is abt 6 hours (light-moderate use). Adding to the misery, I am a heavy user. I love playing games, composing music and sometimes doing homework in my phone. I installed JuiceDefender, SetCPU, Battery Saver Pro (which helped in increasing abt an hour). I listened to almost any piece of advice I got. I read through these forums too.
My previous phone running bada OS (Samsung Wave 525) had awesome battery life, which lasted for 2-3 days of HEAVY usage. Of course, I can't expect the same from an Android device, but seriously, is it this bad? And why is this happening? Is it because of -
1. The mod/kernel?
2. Worn-out battery? (i doubt it, every app states that the battery is "healthy")
3. Some internal problem in the phone?
Or is this just something every owner of this phone faces?
Sorry for the long post. Help is greatly appreciated. :fingers-crossed:

1. Its not the mod /kernel. Since I use the XDA-Bam kernel 15 cr5. So far no issues and the battery lasts at least full day. with heavy usage.
2. May be. Even I doubt it.
3. Not sure with the internal problem, but i doubt that there wont be any internal problem as well since you are using heavy applications
with out any lag.
suggestion
1. Do battery calibration
2. Recharge full until you get 100%
3. Clear the battery stats with cwm
4 again drain the battery completely.
5. Recharge it full to 100%
see if it works for you
Press thanks if it helps you

I have calibrated my battery already. It had helped in solving a major problem (wrong display of battery stats). But battery life hasn't been improved in any way.

Yes, it's like that. Most people say "heavy usage", but they don't imagine that people actually use their phone all the time. I'm always streaming music via 3G, reading news articles, auto-sync on 24/7, social-networking, and sometimes playing games. My phone doesn't make it through the day.
People that claim that their phones are lasting 2-3 days usually don't have a data plan, don't use wifi that much, don't play games, and don't use facebook. That's great for them, but I like to use my phone, and when you're making the most out of your Android, it'll run out of juice in 6 hours.

Well said man. Nice to see people admitting android being backward in the battery department. I guess battery technology hasn't advanced much yet, compared to smartphones themselves. Manufacturers have to choose between a thin, sleek design with abysmal battery and a "fat" one with more reliability. I guess they prefer the former, which is leading to problems like this...
And yeah, regarding usb charging, i've seen that it doesn't charge as fast as normal wall charging... Is it normal too?

Manufacturers have to choose between a thin, sleek design with abysmal battery and a "fat" one with more reliability. I guess they prefer the former, which is leading to problems like this...
And yeah, regarding usb charging, i've seen that it doesn't charge as fast as normal wall charging... Is it normal too?

I read somewhere that samsung was investigating new hydrogen batteries that would make smartphones to last for some weeks

Yes, it's like that. Most people say "heavy usage", but they don't imagine that people actually use their phone all the time. I'm always streaming music via 3G, reading news articles, auto-sync on 24/7, social-networking, and sometimes playing games. My phone doesn't make it through the day.
People that claim that their phones are lasting 2-3 days usually don't have a data plan, don't use wifi that much, don't play games, and don't use facebook. That's great for them, but I like to use my phone, and when you're making the most out of your Android, it'll run out of juice in 6 hours.
All Android phone are like this. If you're going to use a smartphone, you're going to have to have a charger nearby all the time.

Totally agree with you...mine last less than half a day with normal use similar to yours..it will only last around a day plus if it's in 100% sleep mode

as in my opinion, everything is right with your battery.
u are using ur phone fully, so don't expect to much.
try the better battery stat app, it will show real stones in juice eaters.

I switched from CM9 to GB (Frank mod) mainly due to battery drain. But did not make a difference. However if i keep data off, battery lasts much longer, otherwise it drains around 30% at night. I am pretty sure XXKPQ was much better but don't want to go back. Anyone have other suggestions.

cm9 is not a solution either.
best way is to switch to ddlf2 or xwlf2, bam kernel last version. imo, of course.
and main thing - try to find biggest eater. betterbatterystats will help you.

Frank mod is ddlf2. But still there is battery drain.
Can you offer any advice based on the attached screenshots

here is the answer. lookout antivirus. it keeps your device alive instead of sleeping properly. you really need it?
magic locker is not a friend either. try to disable them first, make some discharge cycles without them and post the screens with screen time as well.

different problem
i dont have drainage problem...bt my phone takes a loooooooooot of time to get charged..... i have to charge for about 6-7 hours for the battery to fully charged frm 10%... i did not have this problem befor i used DDLF2

My suggestion: do not install antivirus apps, they drain the battery like hell! For the night battery endurance, just enable the deep sleep function (I use No frills cpu, you can enable the deep sleep from the settings menu) and set the governor and scheduler as you wish.
Battery drain is no more a problem for me since I'm on the Frank's MOD.
Remember to do a full recharge (with the device turned off) and a wipe battery stats for optimize the recharging time.
Cheers

wakelocks means your phone being unable to go to sleep mode for certain periods of time (usually because of retarded apps).
Antivirus on android/linux = scam.
that 3G Watchdog crap, do you really need it? (is the battery drainage worth it?)
I would say your battery duration seems normal, considering you're actually using your phone nonstop plus there's those crap background apps running all the time.
BUT if you wanna be sure about it, why don't you make a nandroid backup (using recovery mode), then factory reset? That should get you back to a clean ROM installation, then calibraty and test your battery overnight (of course make sure your phone is going to sleep mode and is using proper cpu governor). This is the most reliable way to see if your battery drain is related to usage, or just a faulty battery. Go clean, let it sleep, see how much battery it drains.
After this, restore the nandroid backup and clean your phone accordingly (remove crap apps or whatever).
Good luck!

for those on CM9, search for alpha 11 kernel in the general discussion thread...flash that over CM9 alpha 14
i get 3 days of battery on low usage......its pretty similar to ddlf2 in terms of battery drain for me atleast.....and i get ics too....

you can also use droidwall to block all the applications which use internet wihout any reason. they will block un-authorised access to internet and will surely cut a good volume of data usage but remember this works only if ur device is rooted

Hi I'm on paranoidandroid based on cm10 alpha3 and the battery life is at its best 14 hs!!!!
I will try some alpha 4 and check if battery life is improved, else some GB
