Which provides more battery life.
Im on CM5 now and my battery dies SO FAST you can almost see it going down just watching the screen, i have the screen turned all the way down, use only 2g networks. ever tried to under-clock, when i check battery usage says system idle uses 49%
any ideas ?
Are you serious?
Better yet, don't use the phone at all, that might save the battery.
Dude with those settings its like having a 20th Century device.
Flash another ROM or something, try wiping battery stats, it has been suggested all over the forum...
Why do I even bother...when the mods see this youre a gonner anyway.
It's not so much the ROM, its the apps and widgets you have installed. Some are poorly written, some don't play nice with other apps or certain set ups.
All you can do is install a monitoring app like system panel, and remove the apps that are using alot of CPU.
That's what I have done.

listen pal what im saying is my battery doesnt last for **** since i flased CM5 so im wondering if thats to be expected with CM5 and maybe fixed in CM6. but yea ur super helping that for the sarcastic reply, next time dont bother. ooh and btw i dont have to use the phone for it to die with in like 10 hours it will be idle the entire time and it will die.
Edit : OH LOOKY (Dev)CM's2.6.34.2(NR-6.35)(v0.63_08/16)(git updated-08/16)

and thank you for your helpful reply i will look into the apps i have.
EDIT: Battery usage says system idle is nearly 50% of usage, even after i kill all the apps :[
LOL! Wow, someone's a little edgy...
It's definitely not a "CM5 issue" that would be fixed in CM6 (CM6 is still in RC, CM5 has had several stable releases!) eyegor's suggestion to wipe battery stats was probably good advice believe it or not. Charge full, power off, leave plugged in. Boot into recovery and wipe battery stats. Power down, unplug and start up, let it drain allllll the way.
Check out xda homepage even - a battery calibration post!!
Battery life is pretty variable as you can see in the numerous threads on this topic. CM's forum has one with a poll with most saying CM6 is better, but not a clear cut answer.
I used SystemPanel's monitor function to identify which app was eating battery. It worked great! My biggest offender was Weather and Toggle widget. I loved its customization but its battery gulping was just not worth it. Got rid of it and my battery life is much more consistent.
I also got a cheapie battery off eBay which helped.
Both CM5 and 6 run perfect on my phone. No battery drains.
My point was that you're in the wrong section, pal.
You also might want to watch logcat while the phone is idle or sleeping to see if there are numerous errors or warnings scrolling by when there should be very little activity.
I have a similar issue. Initially I had the rediculous drain, but as mentioned wiping battery stats from recovery fixed it for the most part. Once it says its fully charged and you turn the phone off, let it sit charging overnight. Then wipe the stats in the morning and don't charge again until the phone turns itself off. Only issue I have now is that when I've got my GPS turned on, in use or not, it kills the battery. While in use I get about 2 hours from a full battery to the phone turning itself off. Haven't figured that one out.

No worries. It freaked me out when I first flashed 5.0.8. I use my phone as an MP3 player in my truck with it plugged in to my CD players AUX Jack. Did a 5 hour road trip and only lost around 10% including a few phone calls.

As I've noticed people ate flooding the threads with battery issues
I thought some tips might help
1. Wipe battery stats once and only doing it when switching between liberated and cm6, don't do it everytime u flash over a newer version of the rom
2. Use minimal brightness and do not use auto, although it may seem like it helps it doesn't, someone told me this and explained basically using the sensor wastes more batter than it saves
3. Use minimal data and get into the habit of shutting it off right after your done or set it on 2g for those who need the notifications, yes it might take a few seconds more to download but its better than the phone being dead
4. Don't let the phone completely die its bad for the battery, I've got into the habit to charge it every night even if it is full and its shown improvement
5. Leave the thing alone!!! If you need the phone don't play games, or anything else that drains it

How do we set Aria to 2g ? I want to turn off 3G however not finding any option. Battery life is terrible with Aria.
if you are on stock/liberated use the dialer to put in *#*#4636#*#* (speed is neccesary)>>phone info>>prefered newtwork type>>gsm only
cm6 has a toggle in the network settings/power manager
I've seen a couple posts, in other forums, that a task killer will hurt battery life more than improve it. Is this true? If so, why?
Also, I wiped battery stats more than I should've. Did that do permanent damage or will it fix itself over time?

some programs you cant kill so it makes the cpu jump to 100% which drains the battery
i personally find out which programs pop back up and put them on a ignore list to make it drain less
it isnt permanent it will fix over time just charge it fully and dont let it go past 15% and it should improve over time
If your in a 3g saturated area the 3g will contantly swap towers even with screen off, when i first got my phone i could sit and watch the battery level drop about 1% every 10 seconds to get around this open phones dialer and dial *#*#4636#*#* and under phone status select gsm only you use same method to swap back to WCDMA prefered for 3g if you need to use wifi tether or need high speed but this was like a whole new phone for me battery wise. will be neet if there is an app that enables 3g for like browser or maps or something like that and then swapps back to edge when not using something that would need it. if there is already one out there lemme know i could use it.

edit: nevermind i just read that it is not possible to over charge a batty but it is bad to leave it charging for more than 24 hours because it will over heat and can cause internal damage to battery and to phone

Been running it on my Aria on CM6.1-RC1. So far running as advertised. In areas with weaker 3g coverage, switching to 2g has cut my battery usage in about half. I've really only used this to turn off 3g, as I need 2g on all the time for push gmail and im, and am using setCPU for cpu clocking.

Interesting. I was wondering about this the other, thinking that perhaps my battery life has gotten worse since I put the phone in a silicone case. Is that perhaps holding heat in/creating overheating and battery drainage?

from what i can tell, battery life is MOSTLY tied to the kernal. Try an undervolted one, i've found they all work pretty well (hydra and KK)
o alright im using kings #2 BFS kernel undervolted and underclocked
I research before I got my DINC so I never used the factory battery from day 1. I have the same size battery but is 1750 power rating... I think Verizon has a newer one which was before I got mine...

Not directly related to the ROM. Check out the Hydra kernels. Also, with regards to battery, you need to do some recalibration so it works better. I got the 1750 battery for the DINC and it was dropping battery very fast no matter which ROM/Kernel combination I used. Finally found a thread that discuss how to get the OS to read the battery levels better. As an example, my battery would run down from 100% to 90% within 10-15 mins! After trying the following, everything works better.
Here's the thread: http://forum.xda-developers.com/showthread.php?t=714471&highlight=battery
Here's a summary of what you need to do:
01. Power off phone and change battery to full level (Green light).
02. Unplug the power and plug it back in. It should take another 15-20 mins to go green again (there's a thread discussing this also -- "bump" charge).
03. Turn on phone and go into recovery mode. Remove the battery stats.
04. Reboot phone and use without recharging until the battery drains completed - i.e. phones shuts off. May want to turn it on once it shuts off.
05. Charge normal and you should see a positive change in the battery life.
Hope that helps.
Yeah but how much do you really gain by doing all that? And how often if at all do you have to do it again. I have the 1750 and it seems to depend allot of what kind of signal and which radios are on.

Of course if you had bad or no signal, the phone will use up more battery. Normally when you don't have any signal and you check the battery status, the phone tells you to put it in Airplane mode to conserve battery.
For me, it's worth doing because my battery does not drain as fast for my usage. Since I did this over the past 2 days, I've had the phone one on a single charge with about 6 hours of Awake Time (gaming, Internet, phone calls, texting, emails, some GPS usage) and UP time is 22 hours. And the battery is down to 20%. Definitely an improvement for myself so just try it if you like and see how it works out. Everyone's usage is different so it's hard to quantify.

bump charging before wiping stats makes no difference. bump charge is still necessary regardless. until htc acknowledges its a problem and fixes it on their end, bump charging is a part of our lives if you want a fully charged battery. unless you use an external charger of course.
I charge externally and I still bump charge tho I don't need to power the phone on and off. Also the bump time is much shorter

Bump charge with or without battery stats wipe doesn't seem to make much difference for me. I plug in at home/car/computer and carry a spare battery. Just wish there was a way to turn off 3g and force 2g with Verizon on CDMA phones. That way I could still have data/internet.
I flashed my vibrant to bionix 1.3.1 a while back, pretty much a week after is was released. Its been great up to about 2-3 days ago. I had a full charge at work at today around 2 pm, I got home and checked the battery life at around 6 pm it was at 72%. I sent out about 4 texts lastnight. Got up this morning is was at 44%. I used to get about 2-3 days out of light use. It will probably be dead by 2 pm again today.
What gives?
Network data off -
Black background -
Brightness is the lowest -
Idk maybe randomly reading it wrong? P.s. Why dont people charge their phones at night?!?!? Thats what I do
Oh i do as well usually. But like i said, the battery is starting to drop so fast that by lunch that day it was already at like 49%. By 2 pm is was full and so on. I just dont understand why its dropping so fast thats all.
Might have something to do with the battery
Check what's running in the background. The other night I was just using the phone normally and put it to sleep, checked it a few times and it was dropping 1% every 15 minutes or so. Noticed it kept checking into something. VVM and Market Checkin was running, killed it and it seemed to help. Also discovered (might not be true) that the New MAPS and GMAIL apps constantly check in and drain the battery after removing the updates phone seems to last longer/as it did before..:/
oo maybe that might be it. I Just updated a boat load of my apps a few days ago. P.s. how do you remove just the update?

This is crazy. I just came to xda to post my bionix 1.3.1 battery problem. I been running it for a week and no issues. But this morning I took the phone off the charger and within 10 minutes of using it I was down to 85%. Usually after my morning usage I'd be around 93-95%. But that's not the issue I wanted to post.
I was trying to wait for Black Ice since Frost had the best battery life of any rom I've tried...just not feeling the Frost theme. So I started to download the Frost zip & got the phone on the charger.

Hello,
I use Tytung's ICS 4.0.4 for my T-Mobile HTC HD2 (NAND), I've been using this ROM for months.
As such there is no problem with functioning of the ROM.
But my battery drains at a very fast rate. With 6hrs of use it drains to 20% at lowest brightness and no major applications running (2 applications in background at most).
Data enabled (2G).
What to do? Please help!!
Sent from my T-Mobile HTC HD2 using XDA Premium.
Can you download CurrentWidget from the Play store and give a value in mA? If you mean 6hrs without any usage then that's pretty poor. Try turning on airplane mode to determine whether it's an app or one of your connections that's causing the problem.
In currentwidget, the values should be approximately 4mA drain in standby with any connections enabled and 2mA in standby in airplane mode. Screen on drain varies a lot more.
OK, thanks. will revert back soon.
With screen OFF, networks ON, 2g enabled....drain is 6mA.
With screen OFF, airplane mode ...drain is 5mA.
Sent from my T-Mobile HTC HD2 using XDA Premium.
That's high but shouldn't be causing a drain of 20% in 6 hours. It's probably just draining a lot when you're using the phone, and there's not much you can do other than turning the brightness down which you've done already.
try wiping battery stats through recovery...fully charge your battery then wipe stats and let your battery to get fully discharge before you connect it to a charger for about a week...My battery never lasted more than a half day before doing this...now it lasts more than a day...Hope this works
Okz.. will try this..hope this works.

I wonder if this myth will ever die..
Google engineer Dianne Hackberry has talked about several myths about the Android operating system, including wiping battery stats.
The reasoning behind that piece of advice was something like this: If you, at some point, did not charge your Android device fully (for example, only to 80%), it would supposedly remember that battery level as “fully charged” – in this case, you’d only ever get to use 80% of your battery, which is of course less than optimal. So, if you wipe the battery stats, usually done in ClockWord Mod Recovery, the device would “forget” the previous level, here 80%, and instead charge to the full 100% once again, thereby re-calibrating the battery. Or, as Hackborn puts it in more technical terms:
The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory.
However, as she explains, that’s not the case. Because those battery stats, stored in the batterystats.bin file, are only used to maintain information about what is using the battery when not recharging. That is, it essentially holds the information displayed in the Settings > Battery screen. Nothing more, nothing less. Thus:
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
What’s more, you’ve probably noticed that the battery usage data is reset once you recharge your device anyway. From this you can correctly deduce that the battery stats are wiped as well – every time your device is recharged. More or less every day. If there was any effect, you would’ve noticed it without going into recovery and doing that stuff. Typical placebo, eh?

I’m as confused as a baby in a topless bar...
^Whenever someone asks 'how do I reduce my battery drain', ten people immediately jump in with 'CALIBRATE!!11oneeleven!'. No hate directed at whoever posted that advice here, I understand how easy it is to be misinformed (as I was about using SetCPU ), I just think that rumours like this are too easily presented as facts.

obviously as the guys say don't bother trying my advice
to everyone...
at least now I know not to tell anyone about battery stats again...but now there is a wonder in my head...what made my battery last longer than it did before? I wasn't kidding that it lasts half a day longer than before...obviously battery stats didn't make the job...what did.? :-/

I found out something.... usually I used to keep my 2G ON the whole day...but when I switched my data OFF when not in use...my 6hrs...20% battery remaining changed to 8hrs..n 75% remaining.
That's a huge difference.
Can anyone suggest a good app for this? Switching my data OFF automatically when not in use .!!

I think Juice Defender has this functionality built in.

I would guess that many so called "battery saver" apps might have it, not really sure.
I don't turn off data when not in use automatically but I do use Tasker to turn it off for several hours while I sleep.

Yeah Tasker can do this but it's a paid app. Juice Defender is free and can also do the same thing in this case. I agree that Tasker is awesome but not necessarily for saving battery, more for ease of use.

Has anyone been experiencing bad battery life on the g2? When i first got it a month ago it was amazing easily getting 50+ hours with about 6 hours screen time. But over time its been getting worse. I already did the whole stopping the carrier iq and all that, it still doesnt help much. Now when i go to sleep and wake up 7-8 hours later my battery drains 50% or something like that for no reason, no wifi or anything on or synced. I did see some posts about people experiencing bad battery, this phone is supposed to have amazing battery life whats going on? I rooted my phone, still on stock rom, wondering if anyone has fixed their battery issue. Would installing a new rom like aeon v3 help improve battery like its supposed to be? Its getting frustrating, my gs4 had worse battery but at least the standby times werent as bad as they are on my g2. Any fixes for this?
There has to be something running in the back ground draining battery. If not try finding a battery Conditioning Application

Based on the above it could be a few things.
If you want to check a few things on the phone side you can:
- install GSAM Battery and let it keep an eye on what's actually using your juice. Then either remove, modify, adjust settings, etc, for whatever is using it. If it's an app... delete it. Reinstall it.
- You can try a factory reset
If neither fix it then you can try another ROM, but if your battery is just as bad with a factory reset I'd lean towards the battery. Maybe you have some bad cells.
I've had mine for a bit, and I only lose a little bit if not touched overnight.
My current setup:
- Madhi 4.4 KK ROM (1/18 build)
- Obviously rooted with the above
- Greenify on all my non-necessary apps (hangouts, weather and one other app spared from this)
- All my apps auto-sync features are disabled since I just run it once in a while, and things like mail / etc I don't need push anyways
I get pretty solid life even after a few moths of use now.

first, install betterbatterystats and look for wakelocks, try reseting the device. batterylife also depends on how you use the phone...i can get 9hrs on screen time reading books with still 15% left or drain it in 3-4hrs playing games.

Yes i have downloaded and used gsam battery app. I dont see anything unusual in my stats, also using better battery stats, its been in deep sleep for most of the time, and it doesnt say the phone was on or running when the screen was off. But for some reason i wake up and my battery is decreased by 50% again....I am using greenify and hibernating alot of those annoying apps. I am stopping apps that are running . And on the phones battery manager android system is first with 34% but it says its only been running 11min, and no gps is listed. And my screen on time was 2 hours those are what i foudn when i woke up with 20% left, at night it was 70%. I seriously think my phone is messed up when im using it its not that bad, but for some reason when i go to sleep and leave it alone it dies for no reason....

Ah i am using better battery stats, and nothing seems to be out of the ordinary, its been in deep asleep for most of the time. And the phone doesn't say to be on when it wasnt supposed to. Same thing on the phone battery manager it says android system is 34% with 11min being on,and screen is 2 hours. When i woke up my battery went form 70 to 20%.....i am using greenify, and stopping running processes, like carrier iq an other apps. i dont know whats wrong...this is getting frustrating, i have also factory my phone already, it was fine for a few days but now its constantly draining like crazy at night...i love this phone, but i think mine might be messed up! You think changing the rom would make it go back to normal? Even though my phone isnt supposed to be behaving like this with stock...

I definetly would try it. Also you could try different kernel. But its beginning to sound like there could be a defect in your battery. If nothing helps i would send the phone to LG and let the battery replace. You are still in warranty, right?

my battery has a problem too..
when my phone is idle sometimes the battery level increases by 1 or 2.
when im playing heavy games like gangstar 4 the battery decreases every 2 mins and the temperature reaches 40°C. and when im just browsing it decreases every 3-5 mins with a temperature of 34-36°C. and when im watching kuroko no basket (wifi off) every episode just consume 2-3% of the battery (24 mins. = 2-3%)
and the temperature is about 28-30°C.
I think my battery drain problem depends on the temperature
