Battery life just terrible, need since help plz!!

As title says guys, I don't no why but my battery life is just really bad since I moved from stock 2.1 Rom to custom ROMs :-(
Is it my phone? I can't work pig wot it is. I checked the battery usage #*#*4636*#*#) and it seems the Android system is using A LOT of it. I tried charging with phone off, clearing battery stats, not overcharging, but just can't resolve this issue.
Also, I have sync set to update manually and have mobile internet off always, only on wen needed. Same with WiFi. Screen is on auto and time off screen lock set to 30 seconds
I am using OpenDesire sense Rom
Any help will be really appreciated.
Thanks

I could feel WiFi siginal of 2.2 is much better that stock 2.1,
I suppose that the better performance will bring the fast battery drain,
if your custom ROM support WiFi N mode,
that really makes your battery life short that before.

I have the same problem and same settings as you. I read on other forum that people who updated to official 2.2 have even better battery life.
I cant even squeze 20 hours out of my battery :/

You guys should always post what ROMs you are using...

Opendesire 3.3, its the same with defrost.

i also had really bad battery life on those 2 roms
even doing nothing the phone would just keep dropping
go to official froyo 2.2
neophye roms for me have amazing battery life = 48 hrs..

Agree with cygnet

Is there another non sense rom? I really like stock better...

Check if the phone goes to sleep correctly. Spareparts > battery usage: other usage, since last unplugged.
I had the same problem, until I found out that the phone was not going to sleep. (running and screen on percentages were way off. Almost 100% running and a lot less for screen on.

update to the last radio

I found that after forcing everything to install to SD card my battery life plummeted. There were apps/widgets that should have stayed on the phone. Once I moved these back, battery life was back to normal.
I use Systempanel to see the battery drain graph and could see a pattern to it.

Same issue here, Will try Neophyte tonight
Using this rom http://forum.xda-developers.com/showthread.php?t=741663, and it's fantastic! However batt life on .08 and .20 radio is a shocker. I watched a 1 min trailer on youtube, in and out and I lost 4% battery. Before with OpenDesire I'd be shocked if the battery percentage even twitched slightly.

I use Defrost 1.5a and I just use about 2% every hour when the phone is sleeping, and that's with auto sync and mobile data enabled. (disabled it's 1%/hour)
Always underclock to the lowest mhz when the screen is off using SetCPU and when you do use your phone make sure the brightness isn't too high.
I could make a whole list of tips, but I'm sure you'll find more than enough of those on the net.

I may be dumb but how do you force your phone to go into sleep once screen is turned off ?

(using Cyanogenmod 6)
When your screen is off, your phone should automatically go to sleep. Sometimes widgets or apps keep this from happening (like the music player), making it use battery as if you are constantly working on it.
How I resolved this issue was to find out what app or widget caused this. I ended up starting from a fresh reset, installing first all apps I really use (calendar/message widgets, powerstrip etc.)
I tested by installing an app, rebooting (or sometimes not), check the running time of the phone, turning screen off, and check again in 5 minutes. The phone should go to sleep in about 30 - 40 seconds. I am telling you this, because most apps causing this are widgets/apps running constantly.
However, I found in spareparts also that 'settings' was taking alot of usage time in usage statistics. A simple reboot did the trick from here on. But I am guessing I had installed something which made some app not close properly..
Maybe it is better to have a task manager/killer for these situations.
Running and Screen On percentages should not have too much of a difference if your testing and not using the phone while screen is off (music, bg stuff)

You could try juicedefender, it helps improve battery life by disabling unneeded connections while the phone is not in use

Battery Calibration didn't change anything!!!

Running stable CM 6.1 with cm kernel & followed the steps of calibrating battery & my battery lifes still horrible, currently 1 hour after calibration and already down 2 70% from being on internet & a few texts

have u got spare parts? open it up and look at battery history and the running vs screen on time.
they should be the same but i can almost guarantee that your phone is still running whilst the screen is off. you need to find out the app which is keeping a wakelock on ur device and delete/change its settings

Ok thanx..will try this

Sorry for the noobish question, but can I compare the two. I went to spare parts and could not see where to compare screen on time vs running.
I recently tried to calibrate y battery, but sinse my screen does not shut off on its own as before. I've aleady checked the screen timers and all is as it was before.
Right now I am @ 4.5 hrs since I unplugged and I am sitting @ 76%, with little use...kinda sucks!!!!

What kinds of widgets do you have running in the background and how often are they pulling data?
Also, how many days have you been on CM 6.1? I upgraded from RC3 and my battery life is much improved. The first two days it was eating a lot as it 'calibrated' itself but now I can easily make it through a full days use with about 40% to spare.
I adjusted my background widgets and how often they pulled data and this really helped my battery life. Also, a poor signal can have VERY ADVERSE affects on battery life. For example, I work in a prison where cell phone reception is awful. If I am at work for 3 hours and leave the phone in 3G mode, I can easily go through 30% battery while the phone tries to find a signal...

Any idea how long will it take the batt tocalibrate???? I did the recalibration process on thurday night, and my battery sucks now.
I'm sitting on 49% only 4 hours unplugged. Before I was getting somewhere around 55-60% at this time interval...
Any ideas?

Alright boys try this. I got over 2 days worth of lifetime with this set up.
-Download SetCPU
Set your profile to 245/245 screen off with priority at 100%.
-Turn brightness to 0%
-Turn GPS off (Go to Settings->Location and Security-> turn off all that GPS crap
-Leave 3G off until you actually need it, then turn it back off after you're done with it
-Leave bluetooth off
-Don't have garbage widgets lying all over the place on 7 homescreens. I only have like 5 widgets spread out on 2 homescreens.
Are you guys running CM 6.1? Cause I am.
Did you guys overclock?
Thank me if it worked out for you =P

Convolution Thanks for the reply, but im more interested in getting a few more hours but with certain level of freedom. I am not all that interested in switching things on and off every time I need them, but I understand what you mean.
I'm looking to get 16 hours of moderate use...that should be plenty. I currently turn off wi-fi and gps since I seldom use gs, and wifi is governed by a profile manager, and it's on only at night.
but setting connection down to 2G, and killing all screen brightness renders the device (IMHO) useless. Also, SetCPU @245 100%, would really hinder the device.
I am running CM6.1 Stable and I am running OC'd @ 1497, but on "On Demand" profile, so to use only as needed.
I still have to try Pershoot's kernel, I think I will flash it tonight to see what happens.
I am also experiencing some oddity with my screen time-out feature...it's not working.....my screen refuses to turn off by itself, I have to lock the device physically for it to take effect....not sure what changed...but the regular parameters are set properly.

I'm getting 2-3 days with the stock WWE ROM that came with the phone. Brightness is set to Auto, but I keep GPS, BT, WiFi and mobile data connection off until I need them. Other than that, I talk about 20-40 mins/day, send out a few texts, listen to the radio, read my feeds and e-mail - pretty much everything the phone was made for.
IMHO, the "calibration" is bullcrap, it's just an impression that it lasts longer afterwards.

Basically the same setup I have in terms of connectivity except for data.....does it really have that much impact on battery life?
What would I missing if I decide to turn data off?
Thanks!

Huge impact. Try it out for a day or two. Or just install Juice Defender, which disables it while the screen is off, turning it on at set intervals (like for 1 min every half hour) to let it sync.

Thanks Keinengel....I'll look up Juice Defender...sounds like the right thing!

i get atleast a day and a half out of my phone and i had it for about a week now. best battery ive had for a while now.

Wow guys...installed juice defender and pershoot's kernel, and only gone 1% in about 2.5 hour....I'll report again tomorrow

[Q] Whats happening?

I used to be able to leave my phone on standby overnight with 30% of battery with wifi on but whenever I do now it kills the battery and I mean kills it. Its dead to the point of me not being able to boot the phone on and have it shut down on me. I put my charger in and the LED flashes for a while and its only when it stays solid that the phone has enough charge for me to turn it on.
Is this a problem with the ROM or the firmware build its based on or am I missing a setting? WiFi is not on best performance mode and I have selected to turn off after 15mins inactivity?

It's likely to be due to the rom you are using. What rom is it?
It's not necessarily the wifi draining the battery.
The latest MIUI roms are terrible for battery drain relating to the mic not switching off. Post back and I will try and help.

Make sure you check under SETTINGS>>WIRELESS & NETWORKS>>WIRELES SETTINGS then press menu and then Advanced. Make sure the "Best Wifi Performance is unticked, and whilst your here may as well check the sleep timers.
If this doesn't work, then you may want to hunt down the app "Battery Historym for GB" which will allow you to see the battery history in GingerBread Sense based ROMS. this will allow you to look at what has been using the battery. What you are most interested here is the partial wake usage, or what has been stopping the phone from deep sleeping.
It might be the wifi or it might be an app you installed recently.
Make sure you do the usual, Check HTC Sync is not on, and other accounts which can get jammed in the sync process. I find google calendar can do that for me.
Also rememebr to check your radio is matched to your ROM and maybe get SetCPU (Search for it on here for the free for XDA subscribers version) and check your speed settings and governator. Im using Smoothass atm and it runs awesome for me.

Will have to double check on Lees thread but was under the impression the governor you mentioned runs on boot on Leedroid, I have setcpu installed but haven't given it root as I heard of setCPU causing issues with some Sense GB ROMS. I'll try everything else and look at that as a last resort.

Battery life, android OS at 40% normal?

Sorry if this is the wrong section, but it seems like the only section specific to the Captivate Glide.
My wife's Glide is stock, very few widgets (google voice, battery, stock clock) and Android OS shows up at 40% when the phone is idle overnight and during the day during use. She has fb set up on socialhub with only contacts synced, 2 gmail accounts, and Touch(used to be pingchat). wifi is enabled and connected for most of the day. bluetooth is on too, but only connected when in the car.
I don't think it's Touch since I have it on my Atrix and Android OS is at 2-3% for me.
Any ideas?

do you have apps that can access your location? (weather apps, maps etc.) If yes, you may wanna go settings > location and security > and then uncheck "Use wireless network" in case you have not done it yet.

I don't think that's it. I have location enabled on my phone and have a weather widget. The wifes phone does not have a weather widget.

She might have some app that is are using way too much cpu, try doing a factory reset and check the usage, mine is currently %17.
Also the facebook app is a notorious battery thief. Battery usage percentage isn't standard for different people, if she's not using much features, the majority of her battery will be used by the OS since there is nothing else to use it.

Wouldn't phone idle be the max usage? For my Atrix phone idle is at 70% or so when I barely use the phone and Android OS is 3%. I can try disabling facebook overnight to see if the Android OS usage goes down.
The battery life for this phone is ok. It hits ~30% or so in the early evening, meaning we need to charge the phone if she goes out that evening. For my Atrix the battery doesn't hit 30% until midnight under light usage conditions (no games).
Is there an app or logcat keyword to filter to break down exactly which thread/process is using up the CPU?
edit: nm, going to read through this first

From looking at the wakelocks with BetterBatteryStats the likely culprit for the battery usage is the facebook chat portion of the fb app. The wife has many contacts in the chat, so it's probably polling quite a bit. For me the wakelock count for fb chat is fairly low. fb chat is a must for the wife so I can't disable it.
Also in the process screen I see several kworkers with high usage...not sure exactly what's causing that.

so for whatever reason the battery drain is now more acceptable even though the Android OS usage is still at ~50%. Could be the fb update, but the good battery performance occurred before the fb update.

my infuse 4g has a battery drain because of fb.....it's always the next thing that is draining the battery (i hope to get screenies). I just force close fb (or set refresh interval to "never") when I am done using it....
I can't say that this is same as yours but it may be a thing to look up.

From the betterbatterystats output, I'm pretty sure the high Android OS usage is software related and specific to the stock ROM. The radio and wifi battery usage are normal.
I have no clue what the kworker processes are doing when the phone is supposed to be idle. Overnight my Atrix is 68% idle, 12% cell standby...android OS is 2%.

Idk you could try when putting it idle turn of Bluetooth and wifi and the data network this could help see

BT is already off. I could turn off both wifi and data network and if it turns out that is what is causing the battery drain (does not seem like it)...then what? Don't use wifi and the data network? It seems like there's little we can do as an average user to fix the high Android OS usage when idle. It does not seem like high kworker process usage can be fixed by TiBu or other simple fixes from a user.
Another update from Samsung, custom ROMs, and other dev fixes on xda seem to be the only options.

You need to find the source to find a rom that will repair this sometimes an launcher can make your battery die faster I know that Facebook and the browser use a ton of ram I have a stock app on my phone called application manager and I can stop apps that are using my ram

FInd 7a - battery drain and solution thread

Hi
I have received the Find 7a . Tho only issue I have with that is the huge battery drain when off ( even with data and wifi off )
Therefore I want to create a thread where we can share the solutions for this battery drain issue.
PS: I am running ColorOS 2.0 beta
cheers

I dont understand why people keep complaining about the battery. I use my 7a a lot and the battery lasts me just fine and I have Wi-Fi and GPS always on.

It's a known issue, I'm actually in a pilot group with a product manager and developer using a new firmware based on 1.2 that seems to help.
In the meantime, change the lockscreen from Colorlock as that has been known to hold a wakelock and disable Google's location services.
After I did that on 1.2 or 2.0 beta my drain shot down to .5%/hr.

I too am part of said pilot group that Sean mentioned and can confirm that a more battery saving firmware is in the works.
Give oppo some time to work the issue out, it's starting to look better.

Freezing applications/disabling them is basically the same as removing them, except that they still take up space on the system. You can freeze applications using Titanium Backup as you said and if you have root of course. If you want to completely remove the applications you should get a file explorer that can request root permissions, then look for the applications you want to remove, these can usually be found in "/system/app/" or "/system/priv-app/". You can also remove them using adb, this is a little more complicated though, if you want to do it this way I'd recommend you to Google it. Be careful when removing files from the system though, as you may run into some weird situations, you can always make a backup of course. (when restoring back-upped files, remember to set the correct permissions)

enabling google location services do not have impact on standby battery drain, seems changing the lock screen and freezing default launcher (I use Nova) helped
cheers

I dont understand why people keep complaining about the battery. I use my 7a a lot and the battery lasts me just fine and I have Wi-Fi and GPS always on.

I am not seeing any battery drain here. I am still running v1.2.0i and not rooted. I have the password lockscreen and overnight I turn off WiFi and Data and I lose 3% in 8hrs. Pretty good I would say.

I'm on 2.0 beta, changing that to Revolving lock and disabling Google's location services (gimps the phone a bit sure but easy to enable and gps is still fine) and my drain is down to .6%/hr. Not too shabby, and will be testing tonight with location back on.

have been using the find 7a for nearly a week now. all i can say is...be patient, people! the first 2 days i had it, the battery drain is unbearable(8~12hr use and it's gone), but after 3~4 full cycle charged (start charging when below 10% then fully charged using 'battery doctor'), from the 4th day, the battery is amazing, easily get past 24 hours of use with data and wifi always on, screen on time 3 hours+ no problem. my current used time: 34 hr 26 m, with screen on 2 hr 7m, battery still 33%. Google location service is on all the time, Google now is off all the time. GPS off most of the time. running color OS 2.0 beta.
so be patient and charge your battery for few full cycles.
i hope this may help you guys.

Even Oppo has publicly stated the massive battery drain is a known issue affecting all Find 7a phones sold to date so I'm thinking denying there is an issue is a bit silly at this point. Also 2 hours screen time with 33% remaining is a terrible performance that sits at approximately half of what this phones current competition is offering.
Having has this from day one I would also point out that one of the problems associated with this is the inconsistency. I normally will see around 15 percent drain overnight but occasionally its as little as 5 or as high as 70. The problematic part comes in when you figure I've spent most nights testing some new scheme to see if I've made any improvements to the standy life.
Nor do I think its a good idea to accept excuses. On my N5 I never turned anything off, bluetooth, wifi, google now, location, etc. All on all the time and never had a problem getting 4 hours of screen time and never used more than 5% over night. That would of course make it nothing special since I haven't owned a phone since back somewhere around the sgs2 that couldn't do the same thing and there have been lots of phones between here and there. You shouldn't have to turn the phones features off to get the phone to work, being forced to means you are getting a sub industry standard experience. Calling it anything else is a lie.
