[Q] Battery Life on Froyo (Dream/Sapphire)

Simple Poll.
Have you seen a decrease or increase?

Someone can explain this battery drain?
in a lot of roms based on 2.2.1 there is a big battery drain, in some other there isn't.

Reboot after unplugging from USB and battery drain is gone. For further improvement install SetCPU and reduce min/max frequency. I am getting more or less the same lifetime as with donut ROMs.

OK I have done.. but the problem is that when I use it 3 o 4 minutes (for example I install an application using a file explorer, then I read a message and then I come back to home) m battery get 5% lower...
In standby I lose 10% in 6 - 7 hours (I think this is normal).

I am currently without a computer therefore immune to this USB bug. I flashed CM6.1 to this and the other g1 and both suffered substaintial amounts of battery drain so I nandroid restored back to CSDIv4 and still the lowest frequencies and settings did little to combat the descending digits. So I tried this...
Recalibrated my battery
Flashed SuperWipe.zip
Reboot
Flashed SparksMod's latest
Reboot
Wiped battery stats
Unplugged...reboot
Battery lasted 23 hours the first day never seen anything like it.
Lifes great.

I'm using TMUS-G1-Froyo CM6 remix..
and I'm using the new radio with +14mb.
The rom flies but the battery go down too fast.
I'm using setCPU with 256 - 528 mhz while screen is on, 122 - 256 mhz while screen off.
If I go to battery use in settings I see
Cell standby 45%
display 28%
phone idle 22%
android system 3%
I don't think is normal... cell standby is the battery use by cell radio..
I wonder if the new radio give a big battery drain..

I got real excited when I heard about the new radio and hboot even thought that its exclusion was the source of the the battery issues. Haven't been able to try it as I'm without a up-to-date PC at the moment.
It would be real nice if I could find a seasoned dev who understands battery consumption. I thought the kernal was the main culprit but I've tried two different roms with the same kernal and one has notably better battery life than the other. So confusing.

I can't use my phone with this battery drain...
I will come back to official android OTA-AOSP 1.6.. with +14mb.
So I'll test if this kernel with 14mb is a cause of battery drain.
PS: I'm not a lover of rom customizations.. I think the official roms are the best.
The other are all too heavy. I'm not a fan of cm kernel, that is too heavy for g1.
I would see an official OTA 2.2 without customizations, so every one could customize as he want, and if he want.
PS: OK I flashed AOSP 1.6 using ezBiff_kernel to have 15mb (cause I have new radio and spl, so I can flash roms only using this kernel).
Result: my battery life is similar to froyo 2.2 roms... so the problem is:
1) Kernel? (ezBiff_kernel is based on cyanomod kernel... ... ... heavy as death)
2) New radio/spl?
3) My battery (I don't think so.. it's new battery. I buy it 2 weeks ago and in the beginning it works so well.. but then I flashed new radio/spl and new kernel for 15mb..)

Come now.. the cm pershoot kernels are super optimized so they don't collapse under the heavy as death rom that is usually on top of it..
I get mixed results with that kernel between testing and feedback.
A test phone can idle on wifi+2g for days on the stock g1 battery even after a usb unplug.. but on more common use with syncing services its not performing as well as I'd like..
Some of it is fixed with less swap/compcache or changing clock speeds 122/480 for most the speed but lower voltage levels. Also the interactive governor may work better.. I'm testing these ideas if results are good my next kernels defaults will use them.
Cm/pershoot have some interesting new power management code from other htc devices.. So hopefully soon all will be better. (I merged most of it to my kernel but there are some loose ends.. works well untill the phone locks up.. so no public release yet)

Ok sorry I talk without knowledge. I really don't know the effect of the cm kernel. I only know that all roms based on cm release, with cm kernel, are so heavy and slow.
I like your rom (2.2.1 AOSP) and I love your new way to get 14mb.
But I have this orrible problem. My phone has a lot of battery drain when I use it. With screen off, no problems.
I have never used swap or compcache in this days, and I also try different clock speeds (not over 528mhz).
The result is that when I unlock my phone, I go to settings, I see for example 95% battery. Ok, I return to home, I open a message, I return to home, I open contacts and I scroll some contacts without make calls.
Then I come back to battery settings and I see that is 92-93%..
in 2 minutes of soft use.. I think this is impossible. If I open stupids 2D games... ahah in 5-10 minutes my battery lose 10 - 20%.
I remember 1 year ago, with 1.6 (no cyanomod) my battery was good.
Now it isn't (I have a new battery).
Today I flashed aosp 1.6 with your kernel for 14mb (I have new radio&spl) but nothing... I lose a lot of battery percent as in froyo.
So I think problem is or battery calibration, or something to wipe, or cm kernel, or new radio&spl + your new kernel...
Now I'm recalibrating battery (is at 1% from 2 hours, I'm not using it.. ) then I will recharge for 8 - 9 hours and then wipe battery state, but I have done this process a lot of time without a benefit.
I'll try to remove the new radio+spl (so also using standard kernel) if my battery continue to lose percents so fast.
I'll keep you update on my "story".
PS: Sorry for my bad english!! XD

OK.. after a day of low discharging and a night of 8 hour of recharging, I wiped battery states, I wiped data-cache-ext ecc... I flashed aosp 1.6 and ezbiff kernel..
"battery drain" continue...
I will try tomorrow to reflash death-spl and old radio..
BTW, is normal for hours battery 4v at 90%?
On the back of the battery sais 3.7v... I thought 3.7 was the voltage for 100%

Update
I know this thread is a little old, but I ran into this problem as well. What I found was that the official US radio (2.22.23.02) used considerably more battery than the international one (2.22.19.26i). The other thing I noticed is that switching to "use 2G networks only" in mobile networks settings and disabling data over mobile drastically improved battery life.
I also noticed that wifi used a fair bit of juice so my recommendation is to disable wifi if you're going to be on the go for a bit, and disable data/3g if you're just going to be hanging out in the local webcafe, your/a friend's house, or some other location with wifi access for a while.
If you wanted to be ambitious and cared enough you could write a script to use as a shortcut on the home screen to do the swap automatically (detect which setting(s) are enabled and swap them to the opposite).
With those changes, you should get much better battery life. My thoughts on different Froyo flavors is that possibly different builds have different settings by default. Cyanogen comes with data and 3g enabled by default so this will quickly suck out your battery if you're running your 3g, 2g and wifi antennas all at once.
The stock build (1.6) got about the same battery life as I'm getting now with those settings applied. With either build, having all antennas on all the time will drain your battery very rapidly. Being a little more cognizant of the settings (perhaps you also had it set to 2g only on the stock build) you're using will significantly improve your battery life. And when I say significantly, I mean night and day (but the antenna version definitely does also make a difference... at least in my case).

[Q] CM6 vs Chronos Froyo Battery life

Hello,
Which one has longer battery life? From what I read, Chronos Froyo has longer battery life and also it's more responsive? Why is that?
Can CM6 use the same code as Chronos Froyo for speed and bat life?

I think it depends on overclocking.

I use HO!NO ROM for the CM6 and this weekend i realized that i was 22h without recharge it and was with 80% Battery. No profile set.. no Set CPU... Mobile Data 100% ON!!

I simply can´t understand, why every one has different battery life on same ROM. I know it depends on usage etc. but I´ve heard that HO!NO has huge battery drain

Battery performance is based on how one sets up his phone, overclocking, wifi / 3g usage, media usage etc. But on the same setup , cronos wins.

Ye, why Chronos is better? Isn't base on CM6 too? Or it has it's own modified kernel that's why it's better? Is bat life base on Kernel?

This is based on what exact versions being compared?

I have now tried Cronos for the sake of everyone prasing battery life. I compared every ROM over at least 3 days use and i can say there are no big ddifferences as far as battery life goes between CM 22.11. Froyo 2.0.1 or Cronos 1.6 update1. There is some fluctuation, but nothing too aperent.
Older versions had quite some battery problems, that holds for all ROMs, but now only abaut 20-30% less battery for me on these Froyo ROMs, than on eclair ROMs i had before. For first Froyo ROMs it was like 50% less...

Well, the CM6 on the actual build (0.04) is imho far the best concernig battery-life.
Just a little less good than on SHOLS_U2_36.0 by G.O.T.

Before it was probably Cronos, but nowadays the difference is down to the voltage selected. On Cronos this is lower, so out of the box it should take up less power. However, clock for clock it should essentially the same. The rapid releases of CM6 takes the cake for me

I tried both Cronos 1.6.1 and CM6 25/11, I noticed no great difference.. just a feeling, Cronos runs more smooth at same clock, but they are almost the same!
Sent from my Milestone using XDA App

In my personal experience, Cronos 1.6.1 is currently the best ROM both in terms of battery life and responsivity/relayability. With everything enabled (3G, wireless location service, gmail sync) , is the only ROM that can give me 18 hours plus of battery.

Exactly. I believe both hit battery life with the same tweaks. Then it comes down to the voltage and clock speeds. CM6 should last plenty long too.

Pretty much identical battery life. I use my phone quite heavily so never get more then about 16-18hours. Maybe in long haul there is a difference but not with a well used device.

this. although i haven't updated yet to the latest CM6. my phone once lasts from 2.5-3 days, with minimal mp3 listening and harcore wifi usage.

before the upgrade to cronos 1.6.1 (best froyo to customize) i was using telusV5...
eclair could last even 50 hours without recharge.
froyo is 25 hours at its best.
i use H data always on, gps on, latitude, whatsapp, wireless almost never, i make lots of calls, i read news, play games like angry birds or asphalt5 few minutes.
i tried every combo of mhz and vsel from 1100 74, to 700 46...no significant difference, battery lasts always 24-26 hours.

I use c.m. roms,from about the 10th of november or something,c.m. roms last about twice as much as my stock eclair did,i'm sorry to say that,but if nadlabak didnt exist,cronos wouldnt exist,feeyo is waiting each time for nadlabak to solve each problem and then he will release his own rom.
Whenever nadlabak doesnt publish his work,cronos is stuck...
Nice guy maybe feeyo,but not milestone expert...
I prefer the original thing,wich is more superior in my opinion...

Right but are you comparing it against a tweaked Froyo?
I used STOCK Telus 2.1 back in the day with the Overclock mod at 1000mhz/60vsel.
I used to push email from 8am to 6pm everyday at work. I had terrible reception at work so I would use 2G a lot during the day, but I would always have 30% AT LEAST by bedtime. I go to work at 8:30am and sleep around 12am.
Now I work at a different place, but I got into work at 11am today and left at 6pm. I took a break in the middle to get lunch, but since I work underground, I turn on airplane mode the whole time. It's now midnight (13 hrs since unplugging) and I'm at 40%. I'd say that if I had 50% of my time on airplane mode that's pretty bad. Other than that the other 6 hrs that I was out int he open I got decent reception. I just pushed gmail, sycned Facebook/Twitter hourly and weather every 3 hrs. Not too bad in terms of heavy use. Also I have the 2G toggle on. I just don't see how I'm draining battery this fast.
So in my case Eclair completely dominates. With HONO or TelusLite mod I probably got a little better battery life throughout the day. I dunno. I only had 1 month of work or so during the summer of using those ROMs before I quit and I stopped pushing exchange mail all day long.

You forget something battery gets worse over time. I had very good batery life on Eclair. Now i use Froyo for quite some while at begining veery bad battery life. Now latest releases quite better, but still not there so i went to try Eclair again for a bit and i found out even eclair doesnt have the battery life for me it used to have, battery is just old and its only half a year since i bought. But take this i charge it everydays ometimes more so in half a year a charged it around 200 times. 300times is the number i think battery gets quite worse.

Maybe one of you battery hawks can help me figure out what the major problem I'm having is.
I see people saying they get 24+ hours on a single charge, yet I have a difficult time maintaining 12 hours with minimal usage.
My provider (Bell Canada) does not have a 2G network I can fall back on, so that's one thing that could be causing major drain.
I am using SuperPower (but haven't noticed any major difference there), SetCPU to set processor to 250 when screen is on, 15sec before screen off, wifi off, GPS off, background data off when screen is off, auto-sync off, and data scheduled to be on for 5 minutes every hour.
I use my phone when I commute to check emails, play Angry Birds, and the like, and generally overclock to 700 or 800 Mhz, with 48 or 50 vsel depending.
Using my phone to play a game, check email, or surf the web for 10 minutes can cause it to drop 10-20%, and even when it's totally turned off overnight, if it's not plugged in it can drop to 20% or lower from a full charge just sitting on my end table.
Any suggestions/ideas?
EDIT: I wanted to add that I tend to use the most up to date CM mod, but have been trying Cronos since the battery life was touted so highly. Unfortunately, I find that Cronos drains the battery slightly faster than the 11.25 mod did. Testing the 11.29 version of CM6 currently.

[Q] Custom ROM´s and battery drain

Hello fellow Galaxy owners,
I have been installing various custom ROM´s for about 2 months now, so I guess you could still call me a beginner. Recently it has been difficult to keep up with all the latest and greatest advances in kernels and ROM´s. Being a father I don´t have as much time as I used to, to read through the mountain of information on the forums.
It is for this reason that I ask for some simple advice. I have found that Hamster, Instanity and DocRom ROM´s are all very fine pieces of work and they are blisteringly fast. The GPS is fast, the themes are epic but alas the battery life is pretty bad (well for me at least).
I must admit thought that I am obsessed with my phone and I use it constantly to read the news, check emails and stream internet radio while I am driving in my car on a daily basis.
I currently have DocRom slim V3 installed after having done a complete fresh installation. But despite being fast it seems to be very hungry on the power consumption.
Do I need to cycle it through some complete battery discharge cycles and fully charge it, then reset the battery stats in CWM recovery? Does it need some days to settle? Or should I flash different Kernels and see which one gives me the best life? If the latter then which kernel do you recommend for JPU?
Thanks in advance!

Same here
With 3g my I9000 die after 10 hours!
With 2g die after 14 hours!
With data network mode deactivated die after 30 hours!
I don't know if changing baseband or kernel will help or not!
BR

I'm having pretty good battery life without any network and LiveWallpapers turned off... just simple black screen it stayed ON for 4 days with some WiFi surfing, PDF reading and music listening player/online radio. So I guess network is draining the most.

DocRom V6.2
I just installed Doc´s ROM v6.2, and it has greatly increased my battery life.

Great to hear this!
I don't know if this is your case, I used to have the beautiful widgets weather widget on my home screen, and after soem time I realized this app was constantly refreshing and consuming LOTS of battery.
If you have it, removing it will increase your battery life too.

I have same problem,i do have the beautiful weather widget installed and think it looks nice on home screen,maybe this is the batt killer??
What other programs does the same? I like the watch and weather widget to be shown..?

[Q] Which custom rom have longest battery life?

I'm not searching for fastest rom, i don't need high processor speed, i just want more battery life. Which rom do you think have longest battery life, and how many hours approximately?
(currently please answer for latest roms, for now JVP based)
You can suggest battery life helper apps also.

It depends on how many widgets you have, how you set your phone up, how you use it, what you have turned on etc etc etc, start with juice defender too tweak your battery life then reassess
Insanity cm 012/glitch

I had 4 days with Ficeto 2.3.4 v4 with moderate use.

That's great. I couldn't use any rom more than two days.

To be more specific here is my approx use:
calls,sms,gsm only, wifi when needed, sync off - manuall, always lowers brightens, angry birds and alchemy sometimes...

I'm using the latest Simply Honey 3.8 ROM with juice defender, I found it lasted me over a day by using just over 50%. But mostly it depends how much and what your using on the day.

F1 SGS V3.0 does it very well. I can use my phone for almost 2 days.
When i busy on the internet and play music, it takes 1 day.

[Q] what kind of battery life do you get from your installed ROM and Kernel?

Okay my old thread was closed because 'it was against the rules to comparing ROM's confused'
So here another thread without 'the comparing'
Which kernel and rom are you using and how is your battery life?:victory:

It's depends. If a rom includes a lot of functionality and runs in the background then will drain your battery for sure. Some rom has power saving mode and stop app using the internet when no needs etc

It obviously depends very much on how you use your phone
For me with light to average usage and Whatsapp, Threema and Calendar/email sync I usually get around 1%/hour with any of the AOSP ROMs I tried, always using Boeffla kernel with Zzzmove governor/battery extreme setting and a battery saver application switching off my mobile network when on WIFI.
With stock based ROMs it may be a slight tad lower, but for me it was too little to make a real difference....
Just my 2 cents
Axel
PS The 1% figure is calculated over 24-48 hours between charging, thus including the nights

Thanks for the reply, but what i mean with this thread is which rom + kernel you used and which work the best for you, but i can't just post that because people are gonna nag about it.

well, As I wrote for me it's pretty independent from the actual ROM. I tried liquid smooth, cm, omni, slim, amcha and resurrection remix.

It depends on usage style... But I am curious if there is any BATTERY BENCH MARKING!! Post if any one finds any that can be shared on this topic.. Cheers

//

Most important and often not taken into account is reception strength.
I measured that when Im on work and phone is iddle battery is eaten about 4% per hour.
At home its less than 2 %. In both cases I have no wifi connection, but wifi is scanning, gsm data is working, but locked at UMTS (3G, not HSxPA) and connected to 3 google accounts and 1 work email.
I saw strange behavior with waking up CPU when iddle.
When connected through usb to computer (linux station) I was watching changes when phone wasnt use at all
Code:
watch -n 5 --differences=permament adb shell cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state
And at home CPU was at lowest possible frequency, at work CPU is jumping, even to highest, but mostly stays bellow 600MHz
Differences are in localisation of antennas. At work I have weak signal, but also I am within range a few antennas, and software in galaxy sometimes is changing, when able to find better reception.
This means of course a lot of wakeup's and battery is eaten much faster.
Returning to the thread I see no point in comparison between different people cause even one device can survive twice longer depends on location.
The longest time in idle without any data connection enabled is 4 days on a yacht, so receptcion was weak, but device wasnt use at all (its about 1% battery per hour).
