Hi,
I installed Gummy 1.2.0 on my vibrant. The first day or two I was getting amazing battery life. For instance with light-medium use, 30% of the battery was gone in 12+ hours, I was amazed. When I was getting this type of battery life Android system was using about 6-7%.
I noticed that as time passed, the battery life started getting worse and worse. I noticed that the Android System was eating up more and more battery even when it was supposed to be in deep sleep. Now Android System is using almost 40%
Has anyone else had the same experience? Great battery life changing to mediocre battery life in a couple of days.
Please advise.
Thanks!!!
I suggest you get Betterbatterystats and that way you can see exactly what is causing the problem. It is available in the market, but there is a free version here in post 2. IIRC the AOS taking so much of your battery life is bc of some errant process that is constantly drawing/polling on the system and causing the dismally high % of use. Find the app, fix it and your problem will be solved.

Yes, another battery life thread but this one is a recent development for me.
I bought the phone on release day so I have some track record with it. I have not had any trouble with my battery life and have always been able to make the day on a charge. However, recently the Cell Standby and Phone Idle has been sucking my battery dry MUCH faster than in the past.
I unplugged my phone this morning and headed out to work as I do every day. I grabbed my phone at around 10am and saw that the battery was down to 58%. I checked that stats and this is what I saw:
Battery Level 58%
3h 46m 59s since unplugged
Cell Standby - 27%
Phone Idle - 20%
Display - 20%
Bluetooth - 11%
Android System 9%
Other stuff that was nominal >5%
Is this normal? Why would Cell Standby and Phone Idle suddenly be draining the battery when it didn't do it before?

More info on your rom? do you have Wifi calling APP? If you have a custom rom, did you do the battery recycle?
Thanks for the reply...
I am on the stock ROM (rooted). I am not ooposed to flashing a new ROM but I definitely don't want to DECREASE my battery life which is what I have seen occurs with some. Are any of the custom ROM's proven to increase battery life?
I don't have Wifi calling and I haven't done the battery recycle. I fell out of 'tweaker' mode a while back and have just been using the phone. I don't think I have even installed any apps since (or before) my battery life seemed to change. About the only thing different is the Market but I don't think that's a problem.
I just looked and it's down to 38% in 6h 24m and I haven't even touched it. It's rediculous. Something is like a parasite in my phone and I don't know what it is. The only thing running in the "Active Applications" is Launcher Pro but that was one of the first things I installed when I got the phone.

I heard recycle of battery is bad?
That's why I've never done

Nero V3 is great for battery life. Also check if you added some apps in the past few weeks. Might be some background sync process taking too much of battery life while in standby.
i've had this issue before and i've found that it was always a rogue app. your best bet is to start uninstalling or freeze them in titanium to find the one that is screwing you up.
one app that was my latest standby hog was beautiful widgets.
Thanks for the tips! I will start removing some apps and see if that helps.

I am not up to speed on the various ROMs. I will go start reading up but is Nero V3 fully functional (camera, GPS, etc.)? I was keeping track of the progress on all of the ROMs but there are now so many and they are updated so frequently it's tough to keep up (at least for me).
Thanks again!
Oops. Double post.
i'm sure it's an app that's causing that. I think a stock rom won't drain that too much.

It may not apply, but I've also noticed that beautiful widgets is a hog.

I've been seeing "ksmd" in better battery stats as eating up a bunch of my battery, and also lots of dhd_wake locks. I've googled both, work very little to show for it. Any ideas? It's weird, running neutrino 2.2 for weeks work great battery life, then this started happening and almost tripled my idle battery drain

I cannot see what it is, but it IS our main source of drainage of battery.
I have read it has to due something about page file and kernel optimization for fetching memory thought. Lets try a Clem kernel and report back
Here, here. Bump on this I'm trying to get my phone into deep sleep mode, not a lot on the net about this process.
On random days i still get massive drain that I'm pretty sure is due to this 'dhd' process. its keeping my phone awake pretty much at all times.
yesterday i had great batt. life, and today, well, its like night and day...
finally found a thread on this issue after posting
http://forum.xda-developers.com/showthread.php?t=1748301
sorry mods, pls delete
Me too ... it's driving me nuts.
I am experiencing this. My battery life is horrendous. Even when I barely touch the phone the battery drains extremely quickly. I have already rooted the phone with a few different roms with the battery setting "fix" to no avail. I'm on at&t. I have disabled wifi and gps. I have tried to use both the stock app killers and 3rd party ones recommended by these forums. My battery monitoring apps (both stock and 3rd party) consistently attribute the battery loss (always more than 90% of battery use) to an android system app. The android system app or file changes from day to day seemingly randomly. Files have included: UltaCfg, com.samsung.app.playreadyui and security storage.
Any help will be extremely* appreciated. I love the phone but it is nearly useless in this state.

I have been experiencing some serious battery drain issues. Looking at my battery stats, "Android System" is responsible for over half of the drainage. These are the only apps that run constantly besides those which the phone requires to operate:
- SetCPU
- HDWidges
- The Weather Channel
- LBE Privacy Guard
- avast! Mobile Security
other phone info is in sig. Any insight/advice??

I am draining my battery as quickly as I can (streaming Netflix through 4G LTE with max screen brightness, max overlclock w/ performance gov) and then i'm going to power off and do a full recharge. this seemed to have fixed similar issues in this thread:
http://forum.xda-developers.com/showthread.php?t=1756776
let you know the results.
edit: suppose i should say that i was not experiencing this issue until i updated KT747 this morning.
this is what i did:
1) drain the battery completely. let the phone die.
2) charge to 100%. do not power the phone on until it is completely charged to 100%.
3) when i powered the phone on I was at 99%. i plugged it in and it went to 100% in about 2 minutes.
this seems to have completely solved my problem. the android system has gone from using 57% of the battery to 6%. it seems like the kernel i was using vastly overestimates the percentage of the battery to allocate to the android system until it "learns" the capacity of the battery

So this worked for you? I am having excessive battery drain with my Telus S3?

I am also a Telus user. I had big time battery drain issues even with trying everything: enabling power savings mode, running Juice Defender, using wifi more, using darker wallpaper, keeping a closer eye on syncing operations, screen brightness and some other stuff.
After about 10 days I went back to the vendor (Futureshop) and convinced them to give me an exchange on the battery. They have a 14 day return/exchange policy for cell phones if you are not completely satisfied. I took some screenshots to argue my case. Thankfully the rep said ok and further explained how much power an AMOLED screen uses. I really didn't want to convince him that I am quite informed on battery drain issus and took the new battery and ran!
Conclusion is the new battery is so much better it's like night and day. I have the capacity now that others have been raving about.
If you can exchange the battery, do it. Then get the new battery and charge it up fully first thing.
Hello there.
I'm getting slightly increased battery drain on my touchpad, compared to the readings that I've done before.
Right now I'm getting between 45 and 55mA drain per hour and I have no idea what could be causing this. Previously my drain was around 30mA,even less. I have tried to wipe the rom and data, with a clean rom and battery monitor widget I'm getting the same results. Current rom: SGA's FnC, no clock, default governor.
The wifi isn't the issue, turning it off gives me 2-3mA decrease in drain, there is something else that's causing this.
Any ideas?
app related maybe
I have the same issue. I had CM9 builds around June/July that had standby drain of around 30mA, later builds increased to around 45mA which didn't change with CM10. I don't think it is app related, as even a fresh CM10 install with gapps reached 45mA for me.
Is there anybody how can confirm 30mA standby drain with a CM10 build? If so, it would be nice to compare the configuration to figure out where the difference comes from. 15mA difference doesn't sound like much but in reality it's about 2 days difference in standby lifetime.
he didnt specify which rom he was using, or his setup, but a lot of variables can cause more battery drain. certain apps can increase battery drain in standby. but personal experience is cm9 should be about 1% per hour. there has been lot of discussion in the rootzwiki forum about battery drain http://rootzwiki.com/topic/21871-rom-official-cyanogenmod-9-nightly-build-discussion/ can't help you with cm10 since i'm not going to use it until it has worked out more of the bugs.
It would have to be an app or background process causing it to not be as low as possible. I typically read 28-30mA when sleeping with CM9 and not much higher 31mA with CM10/AOKP.
Sadly, it appears that it's not ROM related, because I've done full data wipe with both stock latest CM9 and FnC. The only app I've installed is BMW to read the drain values.
16GB model and yes, I've started getting this issue around July or August too, previously my drain was around 30mA.
If I go to Phone Manager > Power Savings > Energy Consumption I have a huge battery drain. I need help
I'd say pretty much everyone is experience a degraded battery after the update. It will probably have to be fixed though an update.
Oh. I see. I have heard that people are not happy with the battery in Lollipop. I haven't really experienced a change that I noticed.

When you say a huge battery drain, do you mean the battery is not lasting as long as it did or you observed a very precipitous drop in battery over a short period of time?
I have noticed a slight change in battery drain but its definitely not during cell standby.
lollipop needs an update real bad ...cell standby is huge in battery stats ...17% in 4 hours without WiFi and data ..this is just ridiculous ...
chrome is another big battery hog ,ever since it was released.
its a shame Google still couldn't fix its drain caused from chrome while running in background .

Go into settings and unchecked it. Should no longer run in background. Google has several issues right now draining battery. There are some work around. But only on cm roms.
After i restarted my phone a couple times it seemed to have fixed the problem. I've also changed my microUSB cable and AC adaptor as well... since I noticed that they actually make a difference.
