thank you for your informative response but i believe that peoples experiences may differ and im just looking for someone to chime in and say:
"hi. ive used perc 10.2 but im getting better battery life now that im using..." rom+kernel+modem
hope its not a bad question
maybe my gallery sensor battery usage shouldnt be as high as it is and i should change it with xxx.apk?
thanks
When I went from Percept10 to Cog4, my battery life about doubled. I didn't realize how bad it was until I got to Cog4. Now it is excellent.
Before it would go 7AM to 5PM and be drained.
Yesterday it went 7AM to 7PM and was at 70% when I threw it on the desk dock.
the answer is in your picutes, top right,
advanced task killers, antivirus, ect KILL THE BATTERY
I know I know task killers are supposed to help...
they dont, i was running a task killer and voltage control, had it to under clock with screen off, underclock default, stock speed under certain contitions and overclock when plugged in only. That had the system "running" slower and less power than stock only doing stock speeds when needed, and my battery was DEAD in 8 hours. Removed them and Im going 24 hours between charging. (battery swap).
and i just dont see the point of antivirus.
try removing them and see how your battery does. also the first month of the phone it will be all over the place....
I've run the following setups:
Cog 3.04 w/: Good battery life once I swapped in JK4 modem and Speedmod Kernel, still had random shutdown error, switched to Paragon.
Paragon 5.1: Again, JK4 and speedmod get me the best battery life so I made sure I had this set up. Ok battery life, phone screen would occasionally go black with no response until I removed and re-inserted the battery, switched to Firefly.
Firefly 2.1-2.3: Battery life is great (JK4 and speedmod by default), I usually get through the day with moderate use and 50% remaining. I'd say that's about 50% in 15 hours. It's fast and the GPS is much better than cog or paragon. I'll wait to see what the devs do with Firefly but I'm curious about cog 4 running on the KB1 Froyo. I also use CPU Tuner to eek out the most battery life when it starts running low.
@G35tr
thanks im gonna give it a try
@Trusselo
yeah, i definitely had 10.2 since the beginning (christmas?). i feel like the sensor gallery issue could be a culprit as well the the task manager and lookout programs but the battery stats info just doesnt reflect the latter.
on top of that its a reoriented i9000 kernel so i feel there are some inherent battery performance losses in that.
i got my phone pretty well customized at this point so it may be time to take that step in search of better battery and flash something new.
a farewell homage:
That not all that bad but seriously get rid of the taskiller and antivirus. Been using android for 3 years and never had a need for antivirus. Newer android versions don't need taskillers as they store unused apps in memory without cpu usage.
I am using torch 1.5 and did a full charge overnight and have been using it this morning for 20 mins with wifi and it is still at 100 percent. if you search around or download a few of the roms...there is a modded gallery.apk that fixes that battery drain. And im using whatever the torch 1.5 setup is didnt pay attention to kernel or modem but it is using the new official froyo.
Change modem file or try super power tht extend life of bettry.

Why not post in the stickied thread in q&a
Tried nearly every rom here and, in my experience, Cog 3.04 has given me the best battery life by far. Kept default kernel and modem.
My usage is generally as follows:
-2 hours playing music
-10-20 sms
-1-2 hours browsing on mixture of wifi and 3g
Battery drain is generally about 30-40% during the day. Very minimal batter drain when idle.
What did you use to show your battery history? the second screen print.
Thanks.
i get between 25-39 hours of battery life running SuperNova JS5, SpeedMod Kernel K13C, ZNKP1 Modem. I run my phone hard all day long and can't ever seem to get it to die.
when was the last time you cleared the battery stats?
1. Connect the phone to the charger with the phone powered on, and allow the phone to charge until it shows 100%
2. Disconnect the phone from the charger, and power it off.
3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the battery indicator shows 100% (you can use vol-up/vol-down to make the indicator come back up when the screen goes to sleep).
3a. Repeat step 1, 2, 3
4. Disconnect the phone from the charger and power it on.
5. Once the phone is powered completely on, power it off again and reconnect it to the charger until the battery indicator shows 100%.
6. Disconnect the phone, power it on, and use it.
7. Use ADB or a Terminal Emulator to run the following command:
Code:
su
rm /data/system/batterystats.bin
7a. Reboot into clock work Recovery, and choose advanced CWM features and select wipe battery stats
do that, then let it die completely before you charge it again.
Glad to see this thread because it has taught me a couple of things. I was one of those people who made the mistake of running Advanced Task Killer. Got rid of that. I also run AVG, but I think I will try to get rid of it and see if it helps me any. I am glad to hear several say that an antivirus is not necessary.
I'm rooted first of all.
Well, wifi, all GPS, and bluetooth off.
my battery was okay, it lasted for a day mostly. and I think about 2 days ago, the battery suddenly getting worse. Everything remains same. I haven't changed any option, but the bettry is suddenly worse.
I don't use my phone that much. like I got a phone call yesterday and today? no texting, no internet, no app uses.
I charged my battery full(til 11am or til noon), then it dies before 5pm.
(Today I charged my phone til 9:40am, got only one single phone call lasted 1-2mins, and my battery is already 47%.)
It's just terrible! Anyone has same prob????
I'm in California BTW.
are you rooted?
what rom/kernel?

I'm rooted and I think it's stock rom.
I just followed the manual perm root process.
It's weird because under same conditions, battery got totally worse than before. It lasted at least for a day, but now, it lasts only 4-5 hrs with same amount of usage under same conditions.
ever figure this out?
Just rooting will not change anything to your battery life. You need to install a rom or a different kernel in order for it to change anything.
Mine too has gotten worse in the last week. I am not rooted. At this point my battery is draining roughly 25% per hour with little or no use. Spare parts shows the most usage on my phone is 0. I have tried getting rid of weather bug, Pandora and sirius. I tried looking for something to explain exactly why 0 takes up 10x more battery than Android system itself and I have came to the conclusion that I am lost. Any direction to the correct forum topic would be appreciated.

Have you tried the "Blockbuster" mod?
1) open the Blockbuster Application, it should ask you to update.
2) once the update has finished open the application back up and
3) navigate to Menu>Settings> "Disable Movie Updates"
Users have reported better battery life.
Thanks for the reply. Yes I have updated and disabled the Blockbuster app. Better yet even I just rebooted my phone and it drained 12% on the battery. How is that possible. I am using my stock battery now and not the extended, so the % would be different with the stock compared to my extended but really I don't think it should use 12% on a reboot.

I guess you and I are on the same page! I charged mine til 9:40 am and went to work yesterday. I got only one phone call that lasted 1-2mins. The battery was already 52%. All GPS was off, bluetooth off, Wifi off, everything off except 4G. I sent a text and received a text, and the battery drained to 46%. After a few mins with no use of the phone, the battery warning sound played. So I had to charge my phone at that point. It is just totally weird. Under same condition and same usage of the phone, the battery lasted for a day at least. (4G was on at the point.) I don't know what cause this problem. Anyways, I just unrooted mine and got a software update via OTA. I don't know if this will fix the problem. Any luck to you yet?
I am going to charge tonight and try current settings tomorrow and see how long battery last. It is to the point if I have to turn all this stuff off, doesn't it defeat the purpose of having a smartphone?

Try ZD Box
Try ZD Box, and use its task killer to stop any programs your not using right then. Pandora is another app that loves to stay on and chew at your battery...
My phone just started doing this as well. I've been using the TBolt for a couple of weeks now.
Just yesterday my battery life took a serious nose dive. I've adjusted all the settings I can and the battery is dropping like a drunk girl's panties...
I'm having to charge it all the time now just to keep it from giving me the low battery warning.
Ok well here it goes . Off charger for 30 mins 7 text ,this post and a restart and down 10% already. Wtf

That's about what mine took on average to reboot. 10-12%.
I'm at 72% after 11 hours of idle usage and that's on the 2750mah extended battery. That would put me at 46% after 12 hours having not touched the phone once. I literally fell asleep as I took it off the charger...
Something is jacked up and I don't know what.
Rooted, Virus ROM B3, 1.8G kernel (forget which).
I've gone to Imoseyon's Sense lean kernel, special edition.
We'll see how that goes...?
Wanted to report back as I think the culprit may be the wireless tether app.
I turned GPS, WiFi and all my sync's back on and the phone is back to giving me decent battery life.
I did some changes with the tether app and I'll report back to see if my suspicions are correct.
So here's a screen grab of my phone's battery. I work 9-5. Started the day with fully charged battery, and end of work day it's almost dead. Honestly, I never thought it would be this bad. I don't play games or watch endless videos on youtube. I've sent about 15 texts messages max, used the phone to make about 4 calls for a max talk time of 6min. And browsed the net for no longer than 5min. I have wifi always off, GPS off, my screen is always set right down to absolute minimum all the time. I have never used live wallpaper, and have a black wallpaper. All I've done to this phone is root it and remove a lot of bloatware. Nothing else. I've read through the forum and came upon this thread:
http://forum.xda-developers.com/showthread.php?t=1092249
So without running the Bali kernel or running any specific rom, Is this the expected battery life for the average person who just leaves the phone completely stock.
*UPDATE*
JuiceDefender works!!! Battery now last much longer. Thanks goes to jager555 for the great suggestion.
Most high end ones are. because android runs things in the background and allows you to customize many settings, Battery life usually looks like that when you first get your phone. That said once you get familiar with your phone you will start to recognize things that run in the background that serve you no purpose and you can stop them or get rid of that app. You can also get custom roms that have great modifications to enhance your battery's life. It takes some experimentation but gone are the days of getting 4 days out of you Razr. Try searching "battery saver" in the market, too.
It could look like this...
Well I have to say that's quite shocking. The average person just has no clue on how to flash roms or anything like it. They just charge their phone and go. It really makes me wonder why Google or the phone manufacturers wouldn't think battery life to be a priority. The battery life isn't just bad, its unacceptably bad.
Thanks for the input though.
Yeah no thats not normal. When i first got this phone i could go up to twelve hours non stop with regular use text here and make some phone calls, watch one or two videos... And i still had battery left probably like 40% maybe less. Well at least for me i dont know if i was a special case or not.

if you are on stock and do not use the bali kernel, get Juice Defender from the market. try it out for 2 days and get back to me on how it works. if you want the best battery life, especially since you take off gps and wifi, set it to aggressive. that should make the battery last MUCH longer with your type of usage. but once again, use it for 2-3 days for it to settle in properly

yea, my dad is on stock with this phone and it wouldnt last from 7am to 2pm. now it lasts from 7am to at least 8pm with the same type of usage. its a neat program. i hope it works well for you.
I'll second juice defender. Even the free beta version has helped my phone last a long time. but if you aren't using your phone much, you should really get a lot better battery life than that. if it's brand new, it can take the battery a couple of charges from a full drain to get up to snuff.
With light use, I can get well over 2 days, and have even gotten over 3. Here's a screenshot I took a couple of weeks ago.
mike-y was the one who introduced me to juice defender, btw. great find, man
Wow, Tempott, that's very short battery life. I actually had pretty decent battery life on stock. I lasted about 12 hours on moderate use. Then again, it's funny that I last 18 hours on very heavy use now with ICBINB with 4G on, first level brightness, and sync always on (no JuiceDefender, etc.).
i am using Audiophile ROM. i get 10-15h of battery life.
Im using black ice with bali 3.1uv dsexton's build.prop and im getting round 12-15 with heavy use(mobile AP, pandora, calls)

Sorry for the late reply, but I just wanted to give the app a thorough usage. I'm happy to say it really makes a difference. I was so disappointed with the battery life that I had a serious bout of buyer's remorse. This App made a world of difference. Thanks for the suggestion! Glad to have this phone now. Check out the screen shot!
Nice!! that's great. I liked the beta app so much I went ahead and paid for the "plus" version. "Plus" gives JD control over wifi, and lets you set a "night mode" that turns off data/wifi/gps/bluetooth during the night when you sleep. There is also app control, which I played with, but ended up just disabling it (makes things a lot simpler).
Honestly, if the beta is working for you, there isn't much need for the paid versions. especially if you put your phone in airplane mode when you got to sleep (or just turn it off).
btw, current uptime = 40 hours, 45 mins, and I still have 70% battery left.
It seems to me Battery Calibration doesn't work...however, this phone lasts longer than the Sensation, which personally sucks.
battery calibration works fine. make sure your phone is charged to 100%. check spare parts amd make sure it is at 4200mV. sometimes, if it is not calibrated properly, it will show 100% and not 4200. unplug the phone and immediately plug it back in and you will notice a fluctuation in the numbers. usually, it is a big fluctuation. once you are as close to 4200 as you think you are going to get while the phone is plugged in, open the battery calibration app and click calibrate. then immediately unplug the phone. use it until it is completely dead (i do it until i shuts down). once this is done, charge the phone until it is 100%. do no unplug the phone until it is at 100%. then drain it again. and charge it to 100% again. after that, use it normally for 2 to 3 days and you will notice the difference in efficiency.

I would like to add that the first charge drains amazingly fast. You can be idling your phone the whole day, and it'll still be gone.
After you go through a few charges, it'll be omgwtfbbqhax battery life.
Btw, I'm betting Bali 3.3UV + JD is pretty beast battery life compared to Bali 3.3 + JD, right?
Juice defender works great for me as well! Very noticeable difference
Does anyone have success with any Froyo ROMs and Kernels with JuiceDefender?
I have JD Ultimate and the data toggle was not working well on Humble 1.51. I went to Gummy GB with the EXT4 fix and JD data toggle worked but the ROM is giving me lots of problems so I want to go back to Humble. (And the battery drain I am getting even with JD on Gummy GB is pretty bad for me although most are reporting it is great.)
Any thoughts anyone? Thanks in advance.
JuiceDefender doesn't play nice with the Charge, just don't bother. I find all those "battery saving apps" to be useless, they just cause more problems then they are worth. If you want good battery life just use the non-OTB kernel + battery calibration. You can also use the Screen Filter widget and select something like 80%, it will just slightly lower your screen brightness but increase your battery life by quite a lot.
I can make it through the day and still have about 30% battery life by the time I'm going to sleep. That's with moderate/heavy usage, about right in between.
Yep. JD+Charge=no.

Wish I could get that lol. I calibrated mine but still run out halfway through the day. You on 4G?
JD hasn't worked for me on any froyo rom, but it's worked flawlessly on every GB rom I've tried. I'm no dev, but to me, it seems like there must be some kind of bug or abnormality in the rom/modem/something.
JuiceDefender worked great on my Samsung Fascinate. It saved a TON of battery life, especially overnight when I didn't need data.
It screws up the data connection on the Samsung Charge and this is a known issue that the developers of JuiceDefender have known about for months. Just the other day (as in a day or two ago) they FINALLY said they are going to work on the problem, but they didn't give any timeframe.
Be watchful for an update from the marketplace, but don't hold your breath. It may take a while.

Thanks. Unfortunately I have tried everything. The only thing that will work for me is disabling data.
Thanks again for this information and I will let them know I need their assistance!
JD was great with my EVO, but forget about it with the charge.
I have found screen filter to be less effective than just turning the brightness down to 75% or so. I had screen filter set at 55% and my batt last longer with system brightness at 75%. I use switchpro widgets to toggle between 50/75/100.

Always on 4g(aside from those random drops that happen every now and then), you should attempt to re-calibrate and see how it works for you because I love the battery life on this phone(I did come from an enV Touch that had a 4 hour battery life without 4g or even 3g... or apps.... or mods.. basically just a stock phone I had for 2 years)
I have been using JD for about a week and half now on Gummy's latest GB rom and it seems to be working. I have not seen a huge battery difference until today though. For some reason, I was getting big usage from my exchange apps. I had exchange set up with touchdown and the stock e-mail app. With both running, the email app was using over 50% of the battery. I deleted the account and then Touchdown's usage did the same.
Today I am at 14hrs and I have 34% left. Previously I was lucky to get 8-10 hrs. Not sure what has changed but it is working. With JD running, I am still seeing the data connection come back up after the screen has been off. I am training it to learn wifi at home so I am switching this on manually right now.
Hopefully it will stay working!
BTW, I have ok 4g during the day and am lucky to get 3g at home.

I used JD as well, in-fact it said my battery life increased by x2.10, I would've kept it but there were seriously some bad data issues, I would set an apps to always be connected and it just wouldn't work. The toggle widget wasn't functioning correctly and it was just a much better experience without the app. I just hope they do fix it for the Charge or that's wasted money.
I noticed data issues when at home as my data connection is spotty. I just switch to wifi now. I have gmail and yahoo running through K9 and I use touchdown for work. I check deal feeds on tweetdeck and use weatherbug and Beautiful widgets. Not an extreme user but JD has been saving me a little juice lately. Today I am at 9.5 hrs with 41% left.
Anyone experiencing battery drain on ICS? I upgraded, rooted, and removed some of the bloatware to help. Thought it was fixed but my tab is dead again. Says the Android OS is taking up my juice. Was never a problem before. Could leave it on standby for days with HC. Now its dead in a day or less.

I initially saw similar behavior, but once I killed the cached processes once, and since have shut down to charge and started new, I haven't seen that behavior.
Do you have WiFi on? Could it be you have apps that are checking to be updated? I know in the past on my phone my Amazon Appstore has a habit of starting itself up and continually checking for updates for itself and for any apps I got from Amazon.
Tried it both ways...wifi on and off.
Try using CPU spy (free in market) or betterbatterystats (free- search for it here on XDA) to see what is eating up your battery exactly.

I noticed that I had a conflict between "Power Savings" settings and the "Display" settings. Putting them both at 1 minute resulted in an always on screen I had to disable the Power Savings to correct the problem.
I did have something odd happen yesterday that seems to have kept my screen on for 4 hours. When I got home and opened my case the tab was very warm, and shut off. And all but entirely out of power, before that it has used about 10 % in 17 hours of standby with about an hour of use, or so.
I think it is possible that an app that previously didn't keep the screen on is now for some reason keeping it on, and I didn't notice when I closed the leather cover.
No issues today, but I am going to try and see if I can find some release notes to tell me about the new download for ICS for the P6210, perhaps this is addressed?
Just to update I installed the betterbatterystats. I showed a couple of things that were keeping my tab awake. Once I fixed those I thought that would be it but it was still draining. I then installed juice defender and had it turn wifi off every time I turned the screen off. That did it. Was never like this before the update but at least its good to know I fixed it.
i suggest checking better battery stats for AudioOut_1 Partial Wakelock. its been draining my phone fast when i upgraded to ICS.
check it here: http://forum.xda-developers.com/showthread.php?t=1629346
now my battery is working great.. i just left my tab for 10 hrs in the locker when i got the tab its still have 97% battery.
for me i just checked and changed my wifi sleep policy from never to when screen turns off and its fine now. :highfive:
I thought about this very issue; I decided to wait.

Did you download the ICS as opensource? Myself, I am deciding to wait for the OFFICIAL verson to be released.
I had the same problem. i even went back to HC to make sure
the issue is not there (it wasn't) and upgraded to ICS
again (full wipe all the time). No luck something keeps
my device unable to go to deep sleep.
Now i'm back at HC again

Did you download the ICS as opensource? Myself, I am deciding to wait for the OFFICIAL verson to be released.

The version is OFFICIAL .
It's just available only for some countries.
i had the huge battery drain issue while in stock ICS..
the tablet simply refused point blank to go into deep sleep.. in HC it would but not in ICS.. i would take the tablet fully charged to work and not use it much there.. by the time i was travelling back it would be 60% drained in not using it througout the day...
recently flashed to aorths CM9 build and all my battery woes are gone.. now when i get back from work the battery is at 96%!!
battery drain during usage is the same but the CM9 build has awesome battery conservation stuffs for when you dont use it..
would suggest everyone who has these battery issues to move to CM9.. really helped for me.
My battery usage on CM9..

Just to update I installed the betterbatterystats. I showed a couple of things that were keeping my tab awake. Once I fixed those I thought that would be it but it was still draining. I then installed juice defender and had it turn wifi off every time I turned the screen off. That did it. Was never like this before the update but at least its good to know I fixed it.

Early results show Juice Defender is helping a lot with mine too. Thanks for the tip!
Next morning: Just the free version of Juice Defender using the default profile took me from 35% overnight drain yesterday down to 3% overnight drain today. That's not bad. It should be even better tomorrow because I've turned off all location services after seeing that BetterBatteryStats says Google location is the worst single offender at keeping wifi going overnight.

I initially saw similar behavior, but once I killed the cached processes once, and since have shut down to charge and started new, I haven't seen that behavior.
Do you have WiFi on? Could it be you have apps that are checking to be updated? I know in the past on my phone my Amazon Appstore has a habit of starting itself up and continually checking for updates for itself and for any apps I got from Amazon.

Could you tell me how you "killed cached processes" please?
I am having similar battery drain. I am in the process of completely charging battery after it drained 40% in sleep mode last night, wifi off in sleep mods, notifications off, sync off.
I have already done a reset to factory, tried draining battery, and recharged in off position.
Nothing is helping so far. I have installed better battery stats, and CPU spy this morning, and will have data tomorrow morning.
thanks for any help

I had the same exact problem ever since the stock ICS update. My Tab Plus is all stock, no mods at all. The battery would completely drain after one day, and I have very little on the Tab Plus. Nothing helped at all, so I finally bit and did a factory wipe. The battery drain stopped immediately, so I started changing the settings back to the way I like it.
Then, next day the battery went completely dead again! I back tracked and figured out exactly what it is which makes absolutely NO SENSE - turning off wifi in sleep was what was draining the battery! See my screen captures. Notice on the first screen shot, as soon as the wifi stays on the battery drop bar stayed almost flat.
I observed a similar behavior on my 100% stock AT&T GS3 phone also, turning wifi off during sleep causes more battery drain.
I'm getting "suspend backoff" under kernel wakelocks which is preventing my tab going to deep sleep when unused. Everytime I wakeup in the morning my tab is dead. The only solution I found was to turn off wifi if I'm not using it. Anyway fixing this?

Juice Defender. The free version of the app, using the default profile, should take care of this.
