[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] Longest battery life ROM?

Hi,
I'm looking for a FroYo 2.2.1 custom ROM which has the longest battery life.
I'm currently using CyanogenMilestone and I can't use my phone during a full day (even in sleep mode).
I don't care about smoothness or anything else.
Which one is the best?
- The FroyoMOD
- Cyanogen Milestone
- Milestone MIUI
- other?
Has anyone tried The FroyoMOD and/or Milestone MIUI and can tell me how many days it lasted?
Thanks.

the best is
motofroyo sense but it bit sluggish
then MIUI
then others like froyo mod n hono froyo

Cronos lasts for a day and a half maybe... I would consider it Cyan-lite hahaha
Honestly though, the eclair mods are much better on battery life. I run TelusLite V5 and I get around 50 - 60 hours on normal use.

Hi. As you said you're running custom 2.2.1. You did reboot after charging (no matter of power or usb)? The 2.2.1 kernel has a bug that prevents it going into the sleep correctly. This can be avoided with rebooting after disconnecting from charger.

Thanks guys, I'll try MotoFroyo Sense and MIUI and then I'll let you know.

[Q] Which rom for best battery?

[Q] Which rom for best battery?

Isn't there like this like few more threads. Even with the same question....
Anyway. Stock + Speedmod kernel + R tweaks. For me atleast. I dont think there is an universal answer to this. Depends mainly on your use.

for example my gt-i9000 is been unplugged for about 10 hours and only 25-26 % drained... with moderate use of wifi (i turn it off only when i sleep) i`m using a stock rom modifyed by me (xxjpu) with jpy baseband and SOK`s kernel with allmost all tweaks enabled -50~-125mv uv around the volt schelduer....ext2 partitioning.... i reached this configuration after many many days of testing roms,kernels,basebands that are suit for me.

Currently using Darkyy 9.3 with speedmod k13c with R tweaks on, getting pretty good battery life in my opinion. Easily over 24 hours with moderate use.

Best ROM for battery life?

Can anyone tell me what is the best ROM for battery life? Or best Kernal/Modem combo?
I dont mind a stripped down ROM.. dont use many features!
I've tried many ROMs life Darky Resurrection 10.2/Simplicity 0.31/Surface 3.1 & 3.2/Juicy 3.0 etc etc. but cant settle on one...
Battery lasts 18hours max.. (some calls/wifi use/fruit ninja for max 30 mins~1 hr)
Have tried recalibrating my battery too..
Currently on Surface 3.2 with Speedmod T24 kernal
thanks

If you prefer Samsung roms, try Milkeys, very good battery life.
CM/Miui , actual Twooey III (Galnet) ist good, pure english actual version also really good battery life.

These threads are worthless. Each users battery usage is going to be COMPLETELY different. It all boils down to your configuration,personal usage, Wi-Fi usage, GPS usage, apps installed, Your settings,what you allow to run in the background, and hundreds of other variables. Plus there are about 62 threads in the forums asking this same exact question with at least 5xs as many different answers.
Anyways. Cm7 is what I use and get about a day and a half if I need to.
Bottom line, no 1 rom is any more spectacular over another one when it comes to battery. Find one you like and take steps to get your battery and usage in sync.

I have tried many many ROMs and cant figure it out.. sometimes suggestions help
My Wi-Fi usage is more, but dont use GPS much, No autosync or Data.. No autobrightness (keep it to a minimum), I try and disable autostarts of almost all apps

Insanity cm032/platypus neo9 redux 5

My Bad.. someone pls move the thread to Q/A

Darky 10.1 + Semaphore 1.4.2 kernel are the best combination I've had so far.
also remember to do "Clear data" of "Media Storage" from "Settings->Applications->Manage Applications" after flashing any kernel or ROM. (to avoid system_server bug that waste CPU)

Surface JVQ
I have observed Surface JVQ goes well for battery life, try that.

Lets say battery life with just wifi always on and which rom last longer? 2days or more??

Best Battery life .. I'd Say FROYO. !

dont wana move back to Froyo.... let stick to Gingerbread

Darky's 10.2 RE here on JVQ, try replacing XXJVO modem with ZSJPG modem, I flashed it a week or so ago after awful battery life & I'm getting easily 2-3 days on same usage as you, you'll want to keep an eye on your 3G, coverage & GPS if you use it just to make sure signal strength in your location is as good as before though.

I don't use 3g at all. Very very less gps.. Will try that, thank u
Also, can you give me a link to the zsjpg modem and howto install/flash. Hav installed darky resurrection..

No worries, find it HERE & makes sure you read as much as you can.

My way to best batteries life is Juwe 5.1 jvq rom + Galaxian Kernel EE. Normal using ( callin, summary more than 3 hours, gaming 3-4 hours, sms, www 2-3 h) on one charging. Finnaly phone was active more than 40h.
The best solution:
1.Rom with dark colours theme, less colours less battery drain.
2.Proper kernel like Galaxian or Talon
3.Proper charging , bumpy charging method.
that's all

Moved to the ZSJPG modem, SpeedMod t24 kernal, a lighter ROM (Surface 3.2).. can already feel the difference!!!

Galaxian kernel seems to be juicing less batt source as compare to semaphore

Juwe's Smart Edition v5.3 XXJVR best battery life for me so far.

75% of Battery free after 18+ hours of use [10-12 calls/books 20+mins/wifi full time/video15+mins]
JUWE"S 5.2 JVQ + Talon 4.4.20-1200 + RFS + 119 sys apps + 60 user apps

Best Battery Life - 3thparty battery?

Currently using the lastest CM7 kang + Etana kernel. While i am pleased with the performance i'm not pleased with the batterylife.
I've been updating Kang and using custum kernels but my batterylife seems to keep descreasing every time i change something. Probably because of the multiple roms version/kernel tweaks which do not always like eachother.
I'd like to start over but before i do i'd like to know which rom/kernel combo is considered to be the best for batterylife + smoothness! Any recommandations?
Second question - i've read several threads about 3thparty batteries but none seem to be conclusive - is there a battery which beats the stock battery?

Did you calibrate battery after flashing ROM?

I use Owain's CM9 with Harsh Kernel and the battery life is amazing!

I got the best battery performance if i am using 313 baseband with 725 10d RIL. I also use WIUI 2.3.30 as a Custom ROM with ETANA - Kernel with LOC - DS -OTF flag ;-)

it happened to me when i first install cm9, even use match ril&bb , the battery die quickly even i do nothing . but after i install harsh' kernel,battery be normal .
so,i suggests you use another kernel for cm7, from top topic in android development forum. hope this can help

I am finding my X2 only lasts about 4-6 hours. i take a couple of fotos/video, use wifi etc and its dead so quick. i read about reseting battery and filling the cells with the OFF charge on Charge method. so far i have charged full while on. restart charge while off. its on what looks like about 95% and has been on 1 extra hour still not full. is it a bug?
ok so next i disabled alot of stuff uninstalled car home etc and run on 2g etc,
is there anything else i need to know for battery life.
i read a tutorial on this site had a huge list of things. ive done those so far.
just cant get the battery to charge full while off charging.

ok did a few of the battery mods used "juice defender" uninstalled car home etc.
on standby with "wireless left on" and sync left on. 10 hours 40 minutes..
is that bad. I THINK THATS REALLY BAD. right?
