[Q] G2 ROM on Desire Z = Lower Battery Life?

Guys,
I've been jumping between ROMs since rooting my phone last week and one thing I've noticed is that my battery life takes a big hit when I'm using the G2 ROM.
You'd think that since it's a lot closer to stock Froyo than the Bell Desire Z ROM it would have better battery life, but that not what I'm seeing.
With both ROMs it seems that they will stay at 100% for a two or three hours and then start coming down - however it's much more dramatic with the G2 ROM and it seems as though it's battery drain gets accelerated.
Has anyone else noticed this?

For my part, while using CM 6.1RC1 the battery drain was amazingly bad.
Under Modaco G2 ROM, it's more reasonable. For casual use for 7h since being unplugged, I'm at 76%.

My phone's been unplugged for almost 7hrs and I'm at 85% battery on my original Bell ROM.
If you have Spare Parts installed, check Battery History. From there click on the "Running" bar. This will tell you how much time the phone has spent "awake" (this excludes the time the display has been on or while on a call).
I'm at 2hrs 18mins (+20mins with the display on).

Give my stock g2 rom a chance and tell me how that compares. I get better bat life out of stock kernel myself. Bet we could use some uv.

I've noticed something new.
I had my SIM card out of my phone today and it's been unplugged for 5hrs with not cellular network (but everything else going via WiFi) and it's still at 99% battery life.
Uptime is 5hrs 53mins with Awake Time at 1hr 36mins.
Is the cellular connection using more battery than it should be?

it looks like a combination of issues.
1. the android system uses a lot of battery
2.cell standby uses a lot of battery but less than android system
i have a unlocked bell desire z.
installed CyanogenMod RC2 but had to roll back to a sense based rom because the battery drain was just too much.

I figured it out, Kik Messenger was the main culprit.
It's been great since I uninstalled that.
To figure it out o had to restore to a clean rom and install one app at a time. At that point id leave my phone alone for a couple hours and check "wake" time under battery history in Spare Parts. If it was more than 10% we had our app.

Best ROM for battery?

What is the best ROM for battery usuage?

Every sense with leedroid kernel...
Sent from my Desire HD using Tapatalk

i use revolution hd 3.1 and its great for performance and battery

I will second that Revolution HD 3.1 makes such a difference to battery life, its much smoother than stock too. Tried CM7 and CoreDroid but they were both a little too battery hungry to be useful.

ROM, Kernel and Radio
I have used LeeDroid HD, Spike CM7 and Android Revolution HD. All with different kernels and radios.
I would think the battery drain has to do with both ROM, Kernel and Radio versions (and maybe more). So it's vital that all the components is compatible. Most ROM devs recommend both a radio and a kernel.
And of cause it depends on all the services and app installed after the flash
Anyway, to you question:
I use the new Spike CM7 build 19 and have great battery life now.
I had problems with no sleep mode on other ROM/Kernel before. (and yes I have tried various patches)

I'm using CM7 latest nightly with mad murdocks battery fix and the the most latest radio and I'm getting 3-5 mA battery drain while in standby (with constant 3g, mobile data and sync on). So I'd say all the roms are quite close to each other when it comes to battery drain nowadays and the battery drain isn't a main concern anymore while choosing between roms.

My friend and myself bought the phones on same day. He runs Revolution and I run LeeDroid. Looks like there is a small advantage with LeeDroid.

i'm using Spike CM7 build 19 flashed with mad-murdock's batfix build7 and my battery life is great

I recommend Android Revolution HD 3.2 for you!
I had 2-3 days of battery with ARHD3.1 all the time!

the only syncing things are mail (every hour) and google (once a day)

I'm not saying that it isn't possible as you can get a week out of the device if you just let it run on standby but as soon as you switch the screen on the consumption jumps to at least around 200mA and add a little gaming, browsing etc the consumption doubles from that (not an exact figure). So what I am saying is that it's kind of false to imply that another rom has way better battery consumption if you really don't use it that much. As it has been implied in many other threads that you just can't get over a day out of the device if you actively use it. It's just maths and there is no way around it as 1230mAhs will only get you that far
It is possible to get a few days by using it as a "regular" phone, it is all really usage dependent, and therefore the times are pretty hard to compare.

I am seeing a battery improvement using Coredroid V4 over Coredroid V3.2.
Today I have given the phone light use, about 4 short phone calls, email browsing, some facebook browsing but no gaming and I am at 73% after 12 hrs from full charge.

Combination of Buzz 1.3.8.2. 1.61GHz kernel, ARHD 3.2 with sense and the recommended radio is working great for me battery- and performance-wize. Using On demand gov at 1.22 GHz with 230-460MHz screen off profile.

I did'nt say that it all depends on the ROM I use, but with my normal mobile phone lifestyle and this ROM I get those battery lifetime. It was ment as an example, because on the other hand, if I use my DHD more frequent with playing games and stuff, I don't get around the 24h with a single battery charge, but that's (like you say) ROM independet because of the big display consumption and the 1230mA battery.
I just wanted to state the ROM I use with my normal battery experience for the thread author to test out.
It all depends on the user

ics and battery life

At first my girlfriend had her Nexus S updated to ics and immediately we noticed a huge difference in how long her battery lasted and she is the furthest thing from a heavy user.
So when I heard that ics ws being released for our phone my first thought was i hope that what she experienced won't be what i do as we have a better phone right?
Well I am sad to say on a stock but rooted rom I experience the same lack of battery life as her.
Now I am no beginner to Android and have changed all sorts of settings available and nothing syncs on its own and when I unplug my phone from charging in the morning I will need to plug my phone in at night before bed as my phone will be completely dead.
I have to say I am very disappointed in the battery life of thr the stock rom and hope some good kernels make it out to help.

Have you tried to find out which app/process is draining your battery? Better Battery Stats can help you identify what is using up your battery.
I had a big keep awake problem when i first installed stock ICS on my T989D. I did a full wipe of the phone and formatted my internal SD card (after backing things up of course), reinstall the same stock ICS and everything works great now. Battery life is about the same as before (stock GB w/ Synergy kernel), which is about 30 hours with moderate use.

Try CM 9. I get almost 2 days of battery life.

Though I am now on AOKP, I had great battery life on stock ICS as well. But, everything is subjective. How many email accounts are being synced? Do you have Facebook / Twitter / G+ updating every hour? Do you have news feeds continuously updating as well?
I have to agree with the poster above. Get Better Battery Stats and find the culprit draining your battery and work from there.

biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

Wait for kernel development. Its underway as we speak. It will make a significant difference.
Some battery saving tips:
- use juicedefender and set it to aggressive mode.
- use romtoolbox or other programs to underclock cpu frequency.
- also try using telus stock ics. Very good battery life.

I have a brand new T989D (I'm new to Android, former iPhone user) and got the ICS upgrade the day I got it (9 days ago). Battery life is terrible, I'm lucky if I get 10 hours of moderate usage. The phone also tends to run very, very hot. Sometimes apps freeze and all I can do is either wait or, in some cases, remove the battery to reboot.
I'm open to any tips that will get this fixed! I haven't rooted yet (no time). I think I will try those wipe tools and reflash the stock ICS ROM.
First post btw - glad to have joined XDA!

Stock, not rooted, my battery life is great. Something is using your battery up, and flashing some exotic kernel isn't going to change that. The stock kernel works fine. You'll want to find the root of the problem. Keep a real-time (or 1-5s interval anyway) eye on the phone's current (mA) usage, and when it's high for no apparent reason, you'll know that whatever is sucking your battery is doing it right then. That should help you characterize the problem. I've noticed when my WCDMA/GSM radio signal sucks, so does the battery life, so I either turn off the radio or switch to GSM only when I'm in that area. If your display is what's eating your battery, well a kernel can't stop that. Turn the brightness down, leave it on auto-brightness, or just deal with it if you need the display on all the time. But if tweaking and modding makes you happy, by all means...

I have the same complaint. The "screen" battery usage is just unacceptable, especially compared to GB. My phone has been draining from a full charge for ~4.5 hours and my screen usage is 70% and battery is down to 65% with hardly 10 minutes of screen-on time.

I use an app called autostarts and you basically enable/disable apps that start running when certain events happen (phone startup, wifi being turned on, incoming call/sms/mms, other apps turning on, etc.). Just make sure you do your homework so you dont disable something critical. Hopefully this app works on ICS. You'll be surprised what different events make certain apps turn on automaticly. Screen, data/wifi, gps and bluetooth are the biggest battery drainers. No matter what Rom you are on if you don't keep control of those items your battery will drain fast. Keep ur screen on auto, let it go off @ 15 seconds ( you have to be pretty used to your phone for that setting not to annoy you), turn OFF your data or wifi when not in use. With bluetooth and gps...well u know that when you use them your battery is gonna drain faster than normal...just keep that in mind. Its all pretty much common sense.
I'm not going to tell you how much battery time I get cuz its nonsense. There are times my phone lasts till the next day and others Im charging it by sundown. Then again Im still on Juggs n Darkside kernel and Im gonna wait a bit still b4 I make the switch. Also don't go by what other people say on battery life cuz if you might not get the same results on that ROM. Everyone of our devices is unique and acts different. Everyone user uses their phone different. You can't define "light, moderate, heavy" use so don't go by that either.

After upgrading to ICS stock unrooted battery life sucked (5-6hrs). I did the whole remove battery, factory reset and still sucked.
Broke down rooted (still stock), downloaded batterycalibration from play, followed the instructions. Easily get over 24hrs before having to charge again. and when I say easily, I mean I still have over 25% left.

Bingo. Vastly different battery life between ROM's is generally BS. Every once in a great while one of these threads has merit but typically someone saying ROM X had "Killer" battery life is clueless and drinking the koolaid. Then a placebo effect takes place. And definitely someones "Heavy" use is subjective. If someone says they get a day out of an android phone they are not heavy users by my definition. It doesn't happen with heavy use. Perhaps the Razr Maxx or another phone with a very large battery but I've had 5 Android phones. If I get past noon it's because I am not using my phone that much and forget about a full day. It's never happened in the 4 years I've used google OS phones. Never.

Battery drain on clean Rom installs.

The last few nights, I have tried a few different JB Roms. All with the same results. My GNex has a full charge before I go to bed, I wake to my phone telling me to charge it 8 hours later. With NO wifi or network data on. This can't be normal.
The roms:
ASCENT 3.0
Jelly Belly 4.0
New Unofficial Cyanogen Release.
No extra apps installed. Purely stock.
Tonight, I'll try it in airplane mode, and see if my network coverage is what's draining the battery. But for the most part I'm never without a signal.
Any ideas or ways I can see if the battery is just bad?
Also, what would the current Verizon radios be? I believe mine are up to date, but I guess that could be an issue if it is indeed my network signal being dropped.

Im on the 07/27 fitsugly cm10 rom with r225 franco kernel and for some reason my battery life has gone through the roof, after 30 hours of being on the battery is still at 56%. Granted im not using it much now but still i've never seen this type of battery life before. Overnight the battery dropped maybe 4% at best, wifi is always on and its fetching emails.

How odd have you tried charging up and resetting the battery stats ? May help

Try better battery stats... I am on gsm nexus.
I tried jelly belly, minco , paranoid android, and xenonHD plus bigxies stock. I've used Francisco Francos kernel on bigxies and that gave good battery life but the others all burned cpu and battery, specifically via Android.mediascanningservice. and maps.
Right now I am back to stock 4.1.1 rooted courtesy of rom toolkit and with better battery stats and cpu spy I have a cool phone.
One thing you should be aware of is if you have a lot of media on your phone the scanning service can take a long time to run and calm down. I I upgraded my bosses razr to ICS and his phone took all night to update I guess he has lots of music on it...
To increase battery life you can install titanium backup and freeze maps, and wallet when I not in use. You can install rescan media from the app store and trunk off media scanning service. Or just buy a bigger battery.
This is not a knock on the custom roms. The rom teams mentioned above they are all awesome and are the reason us crackflashers have so much fun. I have learned lots from this experience and have a better grasp on how my phone works due to the efforts of these devs. For now I am sticking with stock... I'm sure I'll be flashing again soon.

You can never judge a ROM on battery life within a day. Every ROM I flash gets bad battery on the first cycle and most the time even the second cycle. You really have to stick with a ROM/kernel combination for at least a few days to be able to judge battery life. It may just be a placebo effect but I use a battery calibration app each time I flash

Resetting battery stats accomplishes nothing related to battery life or reported percentage. It's been debunked some time back by Google.

CM10 Performance

I've been running the 9/15 nightly, and while I haven't had excellent battery life, it has typically lasted around 8 hours or more. Today was a little different; with only an hour of screen time, my battery was down to 30%. On top of that, it usually takes 3 or 4 presses of the home button to wake my phone up.
EDIT: I forgot to add that my screen usage usually accounts for 60%, or more, of my battery usage--and that's with minimal usage. It always seemed like my screen was draining the battery even when it was off. It is much less now.
I read on the forums that a simple increase of the minimum frequency can resolve the waking issue. However, it didn't; instead, my battery life improved dramatically. I'm used to a pretty jagged and sharp battery graph, but now it's as smooth and linear as I have ever seen it.
Can anyone explain why raising the min freq improved my battery life?

Why don't you update? Its Oct 5th. Maybe give that a try? Old build man.

Well, I've considered it, but I always check the main thread first. It always seems like people are having LTE or GPS issues with the new build. Everything, aside from the battery life and screen waking, has been working exceptionally well. Not to mention, school and work hasn't given me enough free time to experiment with the new builds. I might try this tonight though.

The rom actually updates EVERY DAY you have missed many many updates here is a changelog http://changelog.bbqdroid.org/#d2att/cm10/1349329973

well all devices are not created equal. i suppose its possible that the ideal minimum frequency for your device is a above stock (or whatever you had it at before). raising the minimum frequency can improve cell connection, screen flickering issues, ect (things that cause battery drain).
also i advise you to update your cm build. either that or switch to cm monthly or another rom that doesn't push out critical updates every night. Try a rom that is considered stable like liquidsmooth, slimbean..

On the Oct 3 build and it's very fast. Batter life has been quite bad, have to charge it twice a day. Had a lot of crashing yesterday, phone decided to reboot continuously. Apollo has stopped error persisted until I cleared cache, and keep getting email/exchange devices have stopped errors until I disabled email.
Battery is the only thing that really bugs me though
Not sent from my toilet with a soap bar.

@nccu_eagles & @jefferson9: To be honest, I never realized the minimum frequency affected so many different elements outside of power saving. I admit I haven't kept it up-to-date; I'm always afraid to update after seeing some of the bugs people post. Perhaps I would be better off with a more stable release--at least until the semester is over, which will leave me with much more time to dabble. If I finish my homework in time, I might try a few different roms tonight.
@adammur: Those are the type of bugs that keep me from updating.
On another note, today's battery life has been great. My battery would normally drain between 12-20% an hour. Today, I'm averaging 5% an hour with similar usage. :good: Anyways, thank you guys for the replies. I'll see if I can't find something to better suit me.... for now :fingers-crossed:.

Before playing with the TouchWiz Jellybean Milestone 5 (Firefly) ROM by Drew Garen, I was running the JellyBro's euroskank October 3rd nightly along with LeanKernel as well as JuiceDefender Ultimate...
My Galaxy S3 could literally last 2 days with that setup. It was UNREAL.
The problem is, I really actually do like the TouchWiz interface (I know I know, I'm one of the few).
But if ultimate battery life is your goal with the Samsung Galaxy S3... Do a factory reset / cache wipe and install the Oct 3rd version of JellyBro's euroskank for the d2att... Then go ahead and install yourself the tmobile / AT&T version of leankernel...
You WILL NOT be sorry!

I've been running the 9/15 nightly, and while I haven't had excellent battery life, it has typically lasted around 8 hours or more. Today was a little different; with only an hour of screen time, my battery was down to 30%. On top of that, it usually takes 3 or 4 presses of the home button to wake my phone up.
EDIT: I forgot to add that my screen usage usually accounts for 60%, or more, of my battery usage--and that's with minimal usage. It always seemed like my screen was draining the battery even when it was off. It is much less now.
I read on the forums that a simple increase of the minimum frequency can resolve the waking issue. However, it didn't; instead, my battery life improved dramatically. I'm used to a pretty jagged and sharp battery graph, but now it's as smooth and linear as I have ever seen it.
Can anyone explain why raising the min freq improved my battery life?

What did you increase it to, if you don't mind me asking?

I normally use up-to-the-moment builds (downloading 10/07 ad I write) and my battery life has been reasonable - up to two days total with light use. Seems to me to be a matter of making sure you're not running too many (any?) battery-hogging apps (BetterBatteryStats has been enormously helpful in this respect).

Unfortunately, I was unable to play with anything last night due to homework. I did, however, purchase and install BBS and JD. I'm actually at work right now, so I can't really post much other than a few screenshots.

I increased it from 384 to 486. So far it seems to have helped a lot. I'm actually about to try a couple different ROMs and see how they go. Wish me luck :cyclops:

You are not alone, I enjoy the functions/features of the OTA ROMs.
Notification accessible when in full screen apps, the multi-window screen lets you "clear all" and access task manager&Google Now, the stock dialer has more efficient functions(Displays all calls from a contact if selected, slide right/left to call/send sms)
But going back on topic, I set my cpu to be conservative but I'm not sure if that'll save battery.
I want to be able to game when at work but not have the power-saving setting limit it yet still be able to last me a day. The OTA ROMs' power-saving feature was able to do that.
