[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.

[Q] Why ICS custom roms drain so much battery?

I loved all ICS custom roms I tested (all of them, I think)... but they are really poor in one aspect: the battery life. It's awful... 50% in 3 hours or less with average use. Is there any solution for that? Which one do you guys use? Thanks

I'm using IceLite by zdzihu on my LT15 and my battery performance is great.
I think that some baseband's are better than others for battery, also, I've added this to my build.prop file:
ro.semc.enable.fast_dormancy=false

There's a bug in ICS beta that drains batttery with wifi off, though it doesn't seem to be present in Z's icelite.

It's in all of them, but it's intermittent.
Some days things would be great, then all of a sudden it would start draining the battery like crazy.
Some people never suffer it, but that does not mean the bug is not there, just that they aren't doing whatever is needed to trigger it.

I'm using Z's ICElite and i have the best battery life i ever had. it's even better than on gb arconium. I'm loosing about 1% per hour on idle. Ok the first time i flashed icelite my whole battery was dead in 7 hours and android os drains 80%(!!!) After two times of complete charging my phone android os drains only 18% and I think this will get even better after charging a few more times

So it seems that Icelite is the the best one for some time... I don't really like that rom's style, but i'll give it a try. I believe that when the official ICS is released, they'll fix this, and also will fix the weak wi-fi bug

Same here. I'm using IceLite on my LT15 and the battery performance was great at first, but drains an average 5% per hour on flightmode. (I use flightmode at night, because I need the alarm clock)

ICS Beta ROM in Xperia ARC S
I have installed the ICS Beta ROM in Xperia ARC S.
Why does empty the battery so fast? background process limit cannot be set, it remains at all times the standard limit.

stop nagging about it because it is beta for a test,not for daily rom,wait for a stable release by se,maybe all the issues gone
from the ARC

The only battery drain is linked to the wifi module.
The only solution I found is not using wifi. If I have to use wifi, I reboot the phone after I disable it.
There's no wifi driver in official beta. This driver is not even a beta one and has not been validated by Sony.
There is no battery drain in ICS 4.0.3 either (unlike some says).
Currently, my battery last between 4 and 5 days without data activated (just a few calls and sms). It lasts 2.5 days with moderate data usage (an average of 15 hours with data and sync activated).

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!

Rooting takes 5 seconds. Follow the sticky. Use odin.

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.

Get a gnex extended....maybe a bad battery

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.

[Q] Cyanogenmod 10 battery life on normal usage.

Hi guys,
I recently switched to CM 10 (Android 4.1.2) and the battery life is significantly lower than what I had on the stock ROM and the new Sense UI... I guess.
My phone won't run longer than 10-15 hours a day with normal usage, which means Wi-fi and 3G always on, screen on automatic brightness being used for about 1 hour in total (for one charge). However Android OS, Cell Standby and Phone Idle still account for the most battery usage, which I find weird. I have no wakelocks and my device goes to deep sleep when not used.
Is this normal behavior with the new Cyanogenmod and Jellybean or are my expectations too high? I already read most threads concerning battery life, but most of them discuss problems such as wakelocks or similar issues. My question relates to the normal behavior of CM 10.
I am grateful for all replies on the matter or personal experiences.

It's known that CM10 battery life is worse than stock JB. You can try different kernels and different governors, but it's a trade-off between life and performance.

I don't understand, I thought that CM is stripped out of unnecessary background processes and apps. As long as I'm not using any CPU or GPU intensive apps like games it should consume less battery than the stock ROM. Is there something I'm missing?

Maybe the updated kernel and drivers give better power effeciency. When the JB kernel source is released, hopefully CM10 and other AOSP ROMs will also improve.

You were saying about on screen time?

CM 10 really uses a lot of battery but of you could switch off wifi and 3g when not using, and clearing all the apps frequently in the recent menu may help... My battery then lasts from about the start of the day till night though the batterys now quite old.

That's pretty much my battery life as well. Regarding age, I'm really concerned, as I'm not able to open the phone and just replace it. But I guess that much better smartphones will come along before I consider getting a new battery and it won't be worth it any more.

I get that sometimes as well. I pick up the phone a couple of times and the battery is always at, say, 50%. Then, a couple of hours later I read a message and it suddenly jumps to 41 or lower. But from what I've read that's normal and no cause of concern.

I heard what causes the CM10 to have such an awful battery life is something that was supposed to save power when you lock your phone [Which is normally quiet often] and actually causes it to depelt, so it obvoiusly doesn't affect screen time
CM10 is a horrible ROM, get something else... I used LiquidSmooth for a while, it's a great ROM
Now running ParanoidAndroid 2.53
Btw, Stock ROM had a wonderful battery life, I only realize that now ... lots of ROMs can't reach that much

That's exactly what I did, flashed the old RUU and installed all updates. I don't know how the guys from HTC managed to do it, but the battery life on Android 4.1.1 and Sense 4+ is AMAZING. I easily get 24 hours with normal usage, over 2 days if I'm really careful.

This is what I got during a night sleep with cm 10.
I installed it yesterday so its kinda new tot me. What causes this?

Probably some nasty wakelocks. Install with wipe/factory reset if you didn't so already. Then try betterbatterystats (search xda) to find out what is causing wakelocks.

Need some guidance :/

The note 2 is known to be the complete phone even till this day... right? and its outstanding part is the battery... right?
I see many people get 5 hours minimum screen on time with usage more than me! My max is 5 hours if I'm lucky, mainly only 3 and a half hours screen on a day. Ive tried a bunch of different roms but no luck, even stock with UV but nothing :/
Is there a combination of rom and kernel that someone could recommend me to see if it'll help? I prefer AOSP roms but there battery hasnt been the best for me but maybe with UV itll work out better?
Any help is appreciated

I believe, TW Roms have better battery life than AOSP ones.(haven't proved it) Additional mods, like Note 3 mods or S5 mods, tend to consume more RAM + Battery 'cause they are designed for phones with higher RAM, so try to avoid them. Root apps like Greenify, freezing some apps using TB, and doing the common saving tips(auto brightness, silent mode, off mobile data, etc.) will also help a lot in battery.
Last thing, batteries also tend to degrade in quality, so sometimes it falls short of its expected length of use.
Hope I help even a little.

Hmm I could be more battery cautious, what rom is designed for battery performance like the meanbean rom but that's not for the international version :/

imho, using aosp on n7100 is not a smart choice. in my experience they have almost the same battery drain as sammy. i tried many roms, now i'm testing revolution hd 23 and with some greenifying everything runs smoother, i have 4% of drain during all the night standby with wifi on, i can't get better on any other rom. i think i'll trust this rom for a while. cheers

Hmm I've tried the android revolution rom and it didn't really suit my usage battery wise. I think I may need a new battery since this one has been going for a while :-/
