[Q] Why GB drains battery alot than Froyo? - Samsung Galaxy S (4G Model)

My battery is perfect on KC1 and most of froyo roms. However when i use ANY GB rom, the battery drains like crazy under the same settings. I calibrated the battery and no difference. Anybody got the same issue? and a fix?

The battery stats in Settings > About phone > Battery use can show you what apps are draining your battery the quickest.
Remember there haven't been too many mods made for GB yet like an undervolted/custom kernel. Just wait a little while, it'll come.

Thanks for the reply.
I was comparing both stock Froyo and GB. So the issue has nothing to with modified kernels and stuff i guess. Just wanted to know why GB drains 2-3 times faster than froyo.
BTW, the battery graph shows,
1. Display
2. Android system
3. Android OS
as first three items in the list
any idea?

That'd be just from the phone being on. I noticed it a bit too, but I manually turn off things like Wifi, etc to keep my battery from draining. Right now my phone is at 44% battery after being unplugged for 11 hours, so I see what you mean about the faster battery drain, but nothing as big as 2 to 3 times, that would mean it'd be completely drained in about 6 hours.

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.

[Q] Battery Life Froyo Vs. GB

Just wondering if anyone can help me understand how there can be such a drastic difference in battery life between Froyo and GB. I've been using BAMF Roms mostly since I rooted my T-Bolt and with above average use on 4G half the day, on Wifi the rest, and get 20>24 hrs battery life. I flashed All the GB Roms after each update, because the lockscreen keeps calling me back lol, but I'm lucky if I get 6 hrs usage with the same basic setup.
I charge my phone every morning when I wake up to 100% and rarely have to charge again until the the next morning with BAMF 1.7 unless I'm flashing mods or streaming a lot of audio and video. I went to sleep at 11:30pm last night with 19% battery and woke up with 14%, insane! With BAMF 2.1 the night before, I not only had to charge my phone 2X that day after very little usage, but went to bed the same time with 100% battery and woke up with 47%. That was with everything turned off, wifi, mobile net, and underclocked to 245mhz with the screen off.
I would just like to know how there can be such a big difference, especially with standby time. Thanks.
It is a known fact that GB is more resource hogging than Froyo. Plus the fact that the GB builds we see here are all based on an alpha leak.. which may not be the best representation of GB. It perhaps has to do with how GB handles memory and how much resource it sucks in to accomplish that.
Just my theory.
I guess what I really can't understand is the standby time. If the screen is off, shouldn't the phone be using less resources? 5% loss on Froyo at night compared to 53% loss with GB, seems like a huge difference to me.
Having some serious battery drain too since going to 2.1. Was thinking about trying a different kernel. Have you tried anything. Trying to find a link but think I saw some posts that Imoseyen's kernels were pretty good.

53% loss overnight in standby tells me you probably have a bad app somewhere.
Mine typically loses about 15-20% max overnight on GB Roms.. (and I've used GB theory, Liquid Roms and Gingeritis)...This itself is more than Froyo Rom which for me has been typically about 5% loss max on standby overnight.
Most importantly.. when I am working on the phone.. GB Roms tend to lose charge a lot faster than Froyo Roms.. which is where the real pain is.

I've seen the same thing. After about 4 hours yesterday on my extended battery I dropped 2%!! With a GB ROM I lose 10% per hour-ish. I'm just sticking with FroYo until we get a better GB leak that is more stable. I was on GB/CM7 on my Inspire and the battery life was great so I know GB isn't as bad as it is on our device we just have an early build of GB. It will get better hopefully sooner rather than later.
I'm not sure if its GB or the roms but there are additional features in GB/GB roms that contribute to the battery loss. These battery tips are in chingy's gingeritis post. Go through these and hopefully these will increase your battery life. I didn't come up with these tips. Credits to Boskoel03

Other than re-flashing after the Rom's are updated, no, I have not tried any different kernals because I assume the devs know a lot more than me, so I like to stick with the kernals that come with the Roms.

I checked everything for rouge apps and found nothing excessively using resources, and I have had the same results with Gingeritis and Theory.

Use Titanium Backup to Freeze All User apps (under Batch Option). Do this before you go to bed. In the morning see what the % Loss is.. Then you can Unfreeze them all one by one and find out the culprit.
Last night when I went to bed my GB rom had 63% juice left.. this morning I was at 47%.
Also, I am using liquid Rom w/ stock battery.

Galaxy R battery issue

not dead black screen problem just battery issue usually in battery usage android os shows normally like this(image)
but sometimes it is 60 to 70 % and that battery drain too fast
is it a firmware issue ? or hardware ? my phone is 2 week old
this thing happen to me 2 time only
it happen to my phone at night on standby mode
and what all other aps( in the image) which is showing in battery usage it is all close(from task manager) but it shows it is using battery.
The battery usage being shown is the overall battery juice used by the apps listed since the phone is switched on.
Its basically shows the history of your battery usage and which app/system components have used how much % of your battery.
There's nothing wrong in that, its not a problem as you are assuming it to be and the apps shown there are not necessarily open.
ok thanks
i'll post in future if this problem come again
now android os usage is rising 40 + is it ok ?
Just enjoy the phone bro. Anyways u wont get more than 1~1.5 days ona a single charge except idealized conditions
I received my Galaxy this Thursday and didn't restart it at all until it drained itself yesterday in 14 hours.
After charing my phone to 100% and using it very very little during the day, it had drained itself completely after 14 hours. See the attached screen shots.
Android OS used 75% of my battery. It was completely useless.
Today after charging to 100% during the night it has been running fine. Currently at 68% after 9 hours with average use.
I've seen another thread about Android OS draining battery for SGS2, but I'm not sure there is a conclusion as to what processes causes it.
I suggest a restart if the battery starts draining too fast.
It's always like that with new smartphones. When I bought mine, battery time was just horrible - not even one day of ordinary usage. After few charging cycles (let's say after approx. 2 weeks) it got much much better. Now 2 days is not a problem at all.
Dont know how its works on custom roms/kernels but on stock 2.3.4 battery going down much faster with sd card on. If I put off sd card, battery life is extended. How no idea why.
lol i don't have any sd card yet but this problem occurs sometimes only
restarting works sometimes not every time i checked it
now what i found battery backup and drainage is ok in android phones wait for ICS 4.0.3(officially) lets see if they fix that battery bug. this thing should be solved in galaxy R.

Dude did you turn off Background auto sync ?
Your display usage is 2%, so it seems your phone was not used much by you. I feel you have turned on too many system background apps or something like that.
Do check that & update here if it solves the problem.

I had this problem on stock rom.
I googled around and it seems that Samsung OS has some bug where after switching the wifi off, it still keeps consuming CPU resources.
Try flashing a custom ROM.
I haven't had this problem since the day I shifted to InfectedROM+ardatdat's kernel.

[Q] Why ICS/JB drains the battery so fast?

hi guys, i've been testing ICS and JB roms... all of them are awesome... but there's something that that intrigues me. Why those roms drains the battery so fast? the only thing that i could imagine is that migth be kernel related... what's your opinion about it?
Previous ICS versions were not much battery hungry but last version which incorporated OMX libs is a battery killer, even if used without Gapps. Too much wakelocks!
you're right

mmm that has more sense for me :silly:
well, we should wait for optimizations...
I dont know about others, but for me the performance and battery of cm9 by hephappy is like the stock gb rom. and that is maybe bcoz i dont overclock my phone.
while using the above mentioned rom i used wifi for over 2 hours (just browsing and saw few vids about 10 minutes on youtube) then after turning off wifi i just checked text messages after every 5-6 hours and battery lasted for day and half.
Running ics on p500 is somewhat similar to running windows 7 on PIII pc. ;P
ICS is not more battery hungry. I get the same performance as I do on GB. The problem here is the way your device is set up and the software you use on it. Screen brightness plays a big role on our devices. So does anything which uses data, specially through the cell radio. I use wifi, whatsapp and still get a full day service out of my little P500 on ICS.
When I look under settings > battery, I find that it is the display that drains the battery so fast.
It is gapps which drain the battery.. also the screen backlight
That could be related with hardware acceleration which is one of the key events started from android 4.0, and if we have 3 buffers working on jb now there will be MORE battery drain.

That maybe one of the reason since battery drains more when screen is on. When phone sleeps, battery drain of ics and gb is nearly same....

[Q] Heavy battery drain issue - help troubleshoot

Of late, I have been having heavy drain of battery on my Atrix 2. I am running JB 4.1.2 (672.300.404.ME865.Retail.en.05). Trying to troubleshoot it (including recalibration) since the last few days without luck.
The symptoms...
- Sudden shut down - Have had 50%+ charge levels. Goes down to 5% and shuts down within minutes. (You can see the random drops in the charge levels in the pic)
- Completely drained out battery charges from above 40% when plugged in & charges to 100% in no time. (that 67% charge in the attachment is within 5 mimutes of power plug in)
Does the battery need a replacement?

Try changing battery... even i had same problem with Custom rom. Battery used to last only for 10 to 12 hours but now its more than 17 hours on JB 4.1.2 leak,,,,...Use stock rom. and remove any unncessesary apps and installl ROM again if u want :good:
How old is your Atrix 2? If over a year then battery surely begins to give lesser performance. Disable any other task killer / memory manager & just let OS do its thing. See if installing Media Scan disable from play helps & do not keep using random chargers, make use of original charger as received with phone. Finally see Better Battery Stats. It is said battery stats should never be wiped but see if it helps you and finally search for Apex's better battery life guide for many handy tips.
I disabled notifications, sync, froze higher wakelock apps & my battery life improved a bit but then it is no fun existing in a bare bones environment.

The phone is just about a year and half old. The drop in battery performance is just too drastic, sometimes it doesn't even last an hour after the charge. Will try to go back to original ROM and see if it improves else will probably have to go for a new battery pack.

Use 2G when u dont need high speed.......
Try this app called Greenify https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
(it helps to reduce wakelocks and improves your battery life)

Think mine is clearly a battery issue. Replaced the battery with a new one yesterday and now the phone lasts 6 hrs at least on a single charge.
CM 10.1.3
I couldn't write to developer's forum so I'm asking here.
I've recently firmwared my AT&T A2 CM 10.1.3 and battery drains really fast! The previous build was CM 10.1 (25th of June). I wiped cache and dalvik cache and firmwared CM 10.1.3. At least 3 people report that thie batteries on this ROM drain slow.
What did I do wrong???

Battery life varies so much from user to user that it is impossible to answer your question without A LOT more information.
Go here:
http://forum.xda-developers.com/showthread.php?t=1179809
Download the app and follow the directions in the op. That and reading through that thread itself should tell you everything you need to know about what is using up your battery.
That being said, everyone has different habits and expectations when it comes to their battery. What one person says is good battery life, another will likely say is bad. So just keep in mind that there is not a right or wrong, just what is right or wrong for you.
If I had a dollar for every time I said that, I'd be making money in a very weird way.
Thank you fro your answer. When I used previous version of CM the battery lasted 3 days with minimal using and turning the flight mode at night on.
As long as I installed newer version with JBX kernel the battery lasts 20 hrs max.
Power Tutor says that the most hungry apps are Android System and Kernel
