Kernel Advice - Desire General

I have poor battery life on my desire, it barely lasts 7 hours. I have tried wiping battery stats etc, and have the screen brightness at 50%. I have read that some kernels can greatly improve battery life, is this true? If so, which would you recommend, and do I just flash it like I would a rom? I am using the latest miui.
Cheers,
Steve

They can but finding the underlying app causing the phone not to sleep would be what I'd be looking at. Remove all installed apps and add them 1 at a time and see how the battery goes

Yeah i've tried this, there's nothing draining the battery.

Not at all
Such battery drainage can only be induced by either heavy usage, or phone not being able to go to sleep.
The differences between kernels in custom roms are merely a shades since all of them are pretty much battery efficient. You won't miraculously jump from battery life of 7 hours to 30 hours. Concentrate on your apps or even better, third party Widgets.

Probably a hardware fault then - the OS on it's own with no apps installed shouldn't drain a battery that quickly. Did you also turn off the sync options to test that theory?
Personally sounds like a knackered battery/phone

If it isn't apps/widgets (they are the culprit for heavy usage) then it would prob be a faulty battery. I did a little test last month to see how much battery I could lose in 24 hours. I lost 8%. I guess it could be a baseline to start off with.

trying this now, but any other?
Actually this article from androidcentral is really complete in terms of settings to reduce battery consumption:

You can also have a look at this one from howtogeek:
howtogeek.com/howto/25319/complete-guide-to-maximizing-your-android-phones-battery-life/
When battery drains a lot it is important to find the cause, in this case tools like systempanel are useful, but keep in mind that it is a good thing to stay away from task killers as explained on lifehacker [what are task killers and why you shouldn't use them]:
lifehacker.com/5650894/android-task-killers-explained-what-they-do-and-why-you-shouldnt-use-them
Hope this will help !
A bad battery is mainly due to either it being faulty or by a stupid amount of usage. Remember that using 7 home screens, live wallpaper, widgets, apps running in the background. All of this counts towards usage. I don't know about calibrating a battery. Some people say it works, some say it doesn't.
I did a little useless experiment the other day where I had my phone at 55% battery and I decided to see how much battery would be used over 24 hours with as little usage as possible. I managed to get 8% of the battery used using 2mA. Hope that puts something into perspective for you.
I tried CPU tuner on the stock ROM and it gave some life to my battery, but I've just flashed a new ROM recently, so hopefully it'll work better.

Can you clarify "as little usage as possible" to get that 8%? Do you mean like switching off everything, or simply not using the device but keeping all the apps as they were?

Omg My Battery Life Sucks

calibrate battery thread :]
I've never calibrated my battery and I never will. The phone battery life varies. If your phone is getting hot and dying in two hours, you have a rogue process.
Manage the poorly written applications and you won't even think "battery calibrate" because you'll see upwards of 36 hours of use on your phone.
Realistically, I get about 12 hours of heavy to medium use out of my phone. I do not use any other third party apps to manage my phone except for Quick Info Pro and even that is not used for anything more than status review. I handle memory management through the built-in Manage Applications, services, etc. On weekends, when I'm not texting a lot, I have seen 40 hours without charging.
If you only have stock and never install anyone else's applications, you'll see a huge difference in how applications (poorly written ones) can affect your phone's battery life.
See disclaimer.
Good info from othan, exactly what I tell customers who complain about battery life.

Battery drain -

I am still experiencing high battery drain issues. I am using Badass Battery Stats, and I am seeing high battery use from App Usage (30%), with System (com.htc.launcher) taking 16%.
Is this normal, are you guys seeing similar results? What is your Launcher usage?
I am at 65% after 10 mins of screen usage and 3 hrs of standby.
For comparison, my phone lasted like 35 hrs yesterday/the day before, with ~2 hrs of screen usage.

your best bet is to use BetterBatteryStats and that will give you a more detailed explanation in what is draining your battery when screen is off. Launcher should not really eat that much battery it is normally the screen. so if i was you i would remove that app for one charge cycle and try bbs which you can get from a thread here on xda and found out from that what is eating your battery my friend

*#*#3424#*#* -> More -> Battery Test and if it's faulty ask for a return/exchange. I got around 87% +/- 1 after1 hour of the test.
I actually swapped my unit once already, the last one had drain issues as well. I wonder if it's something on my software end.
BetterBatteryStats couldn't find anything unusual on my last device, but I will try it on this guy as well.
Will try the battery test as well, thank you.
I have a ton of contacts (1k+) that got imported from my Gmail. I wonder if the device is trying to sync those, which causes some of the battery issues - since the included "Contacts" package is indicated in the screenshot I attached.
I turned off auto-sync for contacts, will see if that helps at all.
solution...

Get Slim ICS installed. I've tried almost every ROM out there for the HOX, and this is by far the best battery consumption I've ever had!
A new ROM is a solution, but was hoping I could get stock working fine first... :/
Do you guys have any suggestions on how to diagnose what could be causing that htc.com.launcher is taking so much battery? I'm up to 25% now.
Is it me or are people using Badass Battery experiencing bad results for battery?
Well let me tell you when I use it I get worse battery. It tells you what is using your battery, but when I decide to disable some of the things it picks up on. I get worse battery life. Also the app itself drains a lot of battery.
I am not an expert, but some the items disabled are integral to the system. And the system trys to enable these apps, but can't. It's like batteries playing hide and seek with the apps and running out of breath.
I got my ram usage down to 490 mb ish with all apps killed, but I had the worst battery life ever. It was draining fast even with the phone in sleep, and I had random apps I disabled starting (Flickr and PDF viewer).
My advice is trial and error. Use the task manager as apposed to these battery heavy apps, and if you find a place where you are getting awesome battery results, stop tinkering!
Edit: a bit enthusiastic in the Ram department.

There's a new battery monitor just come out for free on the play store called carat.
This app's meant to tell you which apps are using your battery and compares it to other phones.
It has to monitor your device for a week before it can give you the results but if it works properly it will be worth it.
have you found a solution? I have the same issue and don't know how to fix
I'm a new user of one x and the battery drain is appalling....i charged it full and was just playing around customizing the phone/settings and i could see it was draining one percent every one to two minutes!
I'm coming from sgs2 although it wasn't great but wasn't as bad as this!
Also, following my customisation etc i changed the sim card and all my customized settings such as wallpaper etc reset back to default!

I, for once was having the same problem..but after one week or two, the battery seems quite stable, and after I played among those beautiful ROMs, I can get the most out of my battery..thank God, I hope you will have the same experience..
Maybe if you wanna stay stock, start to analyze what 'culprit' that actually drained your battery..try using the search bar and use different search terms such as 'battery saving guide' bla bla bla..there are several thread have discussed the same issue..
I am on stock Rom and this is the first full charge after a factory reset although the phone is not brand new but a few months old...

Hi guys..after a few charges it has improved a little but not by much...don't understand why it goes down in 2% increments?
Also i keep hearing random notification type sounds without any notifications...why is this as I'm using stock Rom and unrooted?

Sorry...i know it's the wrong thread for the question but finally why can i see the text message sender's name and the content of the text message inside notification bar even though I've selected not to show this in the stock messaging app settings?
Have a good day...

Try disabling Location & Google Search (Settings -> Location). Noticed that Google services drained 65% of my battery, and heated up the phone. And it only happens when I turn on wifi and update the weather widget, which uses network location service. The drain won't stop until I restarted. Under the services, there's a network location service. So I tried disabling the said setting. Not sure if it will work for you, but it won't harm if you try.

...and that's good?
I got 86%. Is that defective or not?
I got -30mAh when screen is off.
ARHD 7.1.0 + faux 3b10
Is it a acceptable number ?

[Q] Battery drain list

I was thinking why couldn't we sum up all the reasons of battery drain in some thread, so that other's wouldn't have to keep on asking why they were getting one or open a new thread for it.
In almost all cases it's backlight, WiFi, mobile network,bluetooth,GPS, screen time out.
You can also look at battery usage stats in settings to see the responsible app or system setting for battery drain.

How would you go on accomplishing this if everyone has different configurations/settings which affect the drain?

For example, somewhere I read that enabling "flashlight" and "backlight" in quickpanel settings, the battery would drain more.
What I initially thought was that we could post our experiences with bad battery life, the major reasons behind and what we did to solve it. Along with maybe the rom/kernel we would be using.

For over an year, I have flashed my LT15i more than 20 times, trying all the official firmwares meanwhile (all rooted, of course). In my opinion, the daily consumption depends if I used more or less the radios, the players, the screen aso. Because my habits are more or less the same (I listen music and I read/navigate during my half an hour way with the subway, for example) I can affirm that the consumption is constant, around 40% daily. But, I consider that a good estimate could be done following the battery consumption by night. For me, this consumption is around 5%. With one exception: I had installed once an application (from the market!) which downloaded over night almost 10MB of ads, and drained my battery almost 20%! Never ever I have experienced battery drain with official firmwares...
Use BetterBatteryStats and the Android's own included Battery Usage screen and you got all the info you need.

[Q] Battery life

Hello.
I was wondering if my battery life is low or not, so I want to know what your battery life is guyz.
My battery would last like 12hs with wifi always on and facebook, some music here and then and youtube. is it a normal consumption ?
There are so many variables that come into play with battery life that is nearly impossible to quantify what sort of battery life someone should be getting. Screen on time, brightness settings, radios used, reception, usage patterns, apps running in the background....tons of things that will be different from person to person. Also, the actual battery itself comes into play with how well it can hold a charge.
As long as you are happy with your battery situation, all is well. If not, perhaps look into what is using your battery. Better Battery Stats can potentially help you narrow down where things on the software end are draining your battery.

That's about what I use to get.
I went out and bought a spare battery. I'm not a fan of extended batteries so I went with a standard battery for about $10.
I also flashed a new kernel that will help on the screen brightness and underclocking.
