debug battery issue

I'm wondering how i can check which app/app's uses my battery power most.
Just put my Desire away for 1 hour, and even in standby mode i'm losing +/- 5% per hour. I don't think this is normal, so if somebody can help me find the problem i would be really thankful

On your phone dialler press: *#*#4636#*#* then tap battery history. Tap other usage, then choose partial wake usage. This should show you anything that is running while the phone is in standby.

Ok, well not much. I only see the android system is running and my dialer one.

Do you have decent network signal? A poor 3g reception can cause battery drain. Other than that, if you don't have anything preventing the phone from sleeping. I'm lost!

Well my 3g connection is not really strong, but it's terrible either.
Maybe i'll reflash the rom or try another one, and see what happens.

A lot of people swear by Pays 2.1 roms and their battery life, so you might want to test one of them.

And i just got used to the speed of 2.2

Lol, you are not the only person reporting high battery drain on a froyo rom. Nekromantik was also having this issue. He said that 2.1 was much better.
I've tried about every rom out and am back to 2.1 for now.

Maybe i will flash 2.1 back. First i'm going to look for the pay roms you talked about.

HERE they are. I've tried and like the Brave Soul version.

Thnx, downloading now.
Last question. Is there a very big speed defference with the 2.2 roms ? I only know that the linpack benchmarks where amazing with 2.2

To be honest, I don't play games etc on my phone so I don't really know. As far as day to day usage goes I notice no difference in browsing, emailing, texting and calling.

Sometimes i like to play games, just to kill some time
Flashing v2.0 now.

I think my battery is just broken. . .
After flashing it went from 100% to 95 in 3 minutes, when istalling 3 apps.

Had the same problem with the 2.2 ROM. Battery was going very fast. Reflashed Pays 2.1 and everything is better.
Besides I think the Pays has a lot of widgets already in.

So which one do you use. My battery is still running backwards.

Try to wipe your battery stats and put the phone in the charger over the night. Before wiping the battery stats i suffered from a big battery drain aswell, but after wiping it improved.

Battery Drain

Hi All,
When i look into (almost) all roms i see the problem with the battery drain problem.
To bad i do not have the knowledge to find out what to do.
But i think that some smart developers work together to find a solution about this battery drain problem.
So that's why i start this thread so we can discuss this

AdamG's Official Froyo HTC Sense might hold the key to this since it seems to give about 2 days battery performance with the original battery unlike any other rom.

Drain
Tested a lot of roms with froyo and sense. The roms based on 2.06 base are draining relative more then the roms based on 2.04.
Above is not scientificly tested.

Charge to 100% , go to recovery , advanced , wipe battery stats. Enjoy greater baterry life

I had NONE battery drain problems on any of ROMS 2.1 or 2.2, and i did try alot of them.
Maybe theres something wrong with your phone itself (battery).
But definetly try wipe battery stats in recovery.

Since 08:00 morning had WiFi on.. network Data of... and now 12:02 battery is now 90%. DId have play with config the Tasker Tool (Great app).
Tomorrow i will do the test again but then with Network Data on and WiFi off.

people are having mixed results on the battery perfermance of adam's sensefroyo rom. i experienced a poorer battery life compared to eclair (i used Amer_v4 and the battery was excellent) but can still manage to last a full day usually. haven't tried out the froyo roms though.

btw aren't you're using opendesire?

I've changed about 8 roms, mostly used 4, but can't say there was a huge difference between them. 2 days of normal use, 1 day of heavy use.
Possibly shadowfrost and DeFrost 2.4 had the best battery life and I had the fastest kernel installed...
I would think that - some isolated problem aside - mostly it has to do with some applications/settings

sometimes my E-Mail application is consuming most of the cpu. It keeps the cpu at max frequency. Even if i try to end the taks with the app "system panel" it wont solve the problem. I have to go into the app and make a manual sync.
i also found out that automatic brightness is using loads of battery. since i set it to static I'm experiencing almost 2 days of battery life with moderate use.
I'm on Defrost 2.1

Hello again everybody,
Yesterday whole day online by WiFi. Using phone couple of hours and my Maildroid Email was active without prevent sleep mode.
Battery was empty after almost 17hours. (+/- 5% every hour)
Today. Wifi on. Maildroid now with prevent sleep mode ON.
Have unplugged the phone 4 hours ago and battery is at 75%
Tomorrow i will test this with Network Data on.. and without prevent sleep mode of Maildroid. And day after with prevent sleep mode.
I know for sure.. the battery will drain very vast for both situations...
BUT Ill let you know
EDIT 26-07-2010: Battery was empty tonight on 1:30.
NOW I do the whole test again but now with network data on and WiFi off

Ive had the opportunity to own a Nexus One at launch and a HTC Desire...I always found Android OS to be the issue whenever i had excessive battery drain.
Ive found my issue to center around the OS 'calling home to sync' (whether 'sync' option is selected or not)Initially, the problem was resolved by deleting all my sync funtions...but that was obviously not practical........ so now I keep my GSM data connection running and I get about 2.5 days on Open Desire (non HTC Sense).
AdamG seems like the guy who knows what hes talking about - His changelogs for OpenDesire actually hint at him having done some battery drain tweaking...whatever he did, he has definitely fixed it
Cheers

I've tried so many ROMS in the past few weeks to try to solve battery drain issues. On some, I could almost see the percentage dropping as I looked at the home screen! I even bought a new battery thinking I might have killed the original.
OpenDesire does seem to be the way forward re this problem if you're intent on the HAVS kernel. OD2.3a gave me almost two days of varied use.
However, and I know this is going backwards, an earlier DeFrost - the 2.1, is brilliant for me. I'm now at two days since unplug and still at an unbelievable 45% - yes, I know, I thought it was broke as well! For now, I'm sticking with this one. Everything I want works and I don't have to carry a spare battery in my pocket when I go out.
Hope this is of some help. Don't despair. You will find the one for you.
Cheers

I don't get why everyone says they have such a issue with battery.
I get about 2.5-4 days of use with DeFrost 2.2 and have done about so since DeFrost 0.9. I've had it up around five days once.
How are you actually using your phones?
It's not a "Froyo" issue.

It's very interesting to me how are YOU using your phone?
Come on, 4 days ? When i talk about 30m to 1h each day and using a phone little bit, i have at least 30-40% down.
u mean u only drain about 25% each day? are u actually using your phone ? wifi, calls, 3g ? or u have a expensive pocket toy just to show to your friends ?

[Q] Cyanogen 7 radio battery drain

I installed CM7 last night and I'm experiencing high radio battery drain. I love the rom but in a few hours of light usage and I'm down 17% battery. I've also tried rmk40's patch and same problem. Anyone have any solution for the drain?
Sent from my HTC Vision using XDA App

I hope someone can correct me if I'm wrong, but I'm pretty sure that flashing a new rom like CM7 does not change your radio, so it's probably not a radio issue. If I were you, I'd fully charge it, reboot into clockwork recovery, and wipe the battery stats under "advanced". Then drain the battery all the way, and recharge it again fully to recalibrate the battery. See if that helps.

I have the same kind of issues, similar setup. What patch are you talking about? I haven't seen one.
Seems anything radio related INSANELY drains my battery. I don't remember eating my entire battery just because of text messaging quite as badly as I do these days, it's ridiculous. I sure wish there was a definitive answer in the radio and RIL files debate lol.

Anytime you flash a new ROM on your phone, you should let it bake for a couple days before making judgement of battery life, performance, etc etc. I admit I don't always do that myself, but to be fair to the developer you should let your phone get accustomed to the new ROM and/or radio. Give it a 2 or 3 days and let us know if battery life improves or not for you.

I am running cyanogen 7 and my radio signal is very weak now. Is there a way to update the radio? Sorry for the dumb question but I've been reading for 2 days now with no luck. I'm probably not looking in the right places. Thanks for your time.

Its actually most likely the same signal strength, just cm7 and sense builds show it differently. You may show 1 bar on cm7 and 2 on a sense build.
Sent from my HTC Vision using XDA App

Always flash at 100% battery status first. Then use your phone at least 4 days. So with 2 complete drainages and charges. Only after that you can judge if a certain rom is draining or not. O and your radio is NOT changing after you installed a CM7 nightly. This is mentioned a zillion times here. I almost posted the famous quote "If you were to string these posts in a ......."

Some Help in choosing a new ROM. (a few questions)

Hey everyone, this is my first post in this great forum.
I am looking for some help in choosing a new ROM for my HTC desire, the main thing i want to see is the new Gingerbread OS 2.3 and the improvements it brings (battery life), but sadly it has not been officially released to the Desire platform.
EDIT :
Okay now Im on CM7, probably gonna try oxygen later, but till now CM7 suits all my needs and the battery seems good (20 to 26 hours heavy usage) but im running into a small problem.
at 9% the battery dies and phone turns off, battery and phone seem somehow out of sync so 9% means 2% or something, how can i fix this and make it turn off at 2% ?

If it's battery life you're interested in, Oxygen is pretty awesome, but it's AOSP so doesn't have any Sense stuff (widgets, messaging app, camera etc) - there's stuff on the market that provides equivalents/better versions though.
I've just flashed a sense ROM a couple of days ago after coming from Oxygen and I'm missing Oxygen so much that I'll be going back to it tonight It's very fast and stable.
But if you want to stay with Sense, this ROM is as close to stock Gingerbread (with Sense) as you'll get http://forum.xda-developers.com/showthread.php?t=1124810
People have been getting good battery life with that but I've not had too much luck getting great results. It's very smooth though
EDIT: CyanogenMod 7 I can't tell you too much about as I've only briefly flashed it. I remember it didn't feel as "clean" as oxygen but it had a huge amount of customisation potential (though saying that, the latest Oxygen build has almost as much, with the ThemeChooser). Also I don't think CM7's battery life is as good as Oxygen's.
What I'd do if I were you: Flash the CM7r2 HBOOT from http://alpharev.nl/ then flash Oxygen/CM7/SGBS depending on what you want to try first - all 3 work on that HBOOT so if you don't like one you can just flash another quite easily.
Make sure you know what you're doing flashing HBOOT though as there's a risk of bricking associated with it. So just read up first.

Thanks.
I decided to try CM7 7.0.3 for a while and i like it. Alot of customization and some neat features, but the downside is that i dont feel like the Battery consumption has changed at all, its still as i have had my 2.2 froyo stock i think.
I did a small measurment of battery consumtion please tell me if i should be getting these results:
First
-Phone with CM7 rom Charged at 96%
(turned on wifi for like 10minutes, did around 6 phone calls, 1hour looking around settings, animated wallpaper activated for an hour)
After exactly 6hours the battery went down to 76%
So in 6hours the battery decreased 20%
Is this a good result? Will I be getting better battery life in the Oxygen rom ? If so i will definitely switch to Oxygen.

Well that's not exactly bad. I'm currently on 42% after 20 hours 30 minutes with WiFi on syncing emails every hour, a bit of browsing, over an hour of gaming (trial xtreme), some texting, about 20 minutes of calls and some music playing too. Idle it probably uses less than 1% per hour. I'm on the latest oxygen.
I'm really happy with this battery life
I'd recommend downloading battery calibration from the market to get the most from your battery.

Redux is a good ASOP ROM with good battery life - its quite stripped down.
For a sense ROM - I like LeeDroid.

Or completely ruin it. Battery calibration is to be used only if your battery percentage is out of sync with real mV status, so your phone ends up dead at say, 10%. It is not to be used to decrease battery consumption, which is not going to happen. Ever.
To OP, it boils down to your preference. I couldn't care less for ota updates, but if you do, flash ruu, or maybe even rooted stock would work, I'm not sure about that though. As for battery consumption, you had 1 hour screen on, some calls and texts. I'd call that fair.

Yeah you're right. I meant battery monitor widget. It was late at night, forgive me
Battery monitor widget gives you a good idea of what your drain can be attributed to so is a very handy thing to have on your phone. Battery calibration (as the poster above mentioned) is to line up the amounts your phone reports with the true amounts and should only be used if you're getting strange shutdown occurrences etc. Sorry about that
Some people use juice defender too but I don't really like it tbh.

Yeah, those placebo apps are the best
Juice defender, setcpu, task killers, memory menagers etc share the same place in the Hall of sillyness.

To the OP (not erklat)
If you flash a carrier RUU you're all set for ota UPDATES.
If you de-branded the phone yourself, you can still get ota updates, just make sure your goldcard is installed prior to installing the update. If you update without a goldcard you will lose your data connection
If you have a rooted stoc, same as erklat's opinion, I think it should work but I have never tested this myself.

No i read this method and many users are reporting battery damage. I dont want to do this. My battery on regular use (calls, wifi, games,browsing) lasts 26 hours max and on idle it could last like 40 hours or more maybe.
Its just that the phone is turning off at 9% battery.
I used the Battery calibration app suggested before by cgmorris89 but then erklat said that it would ruin things.
What can i do to make my phone turn off at 2% ?

Oxygen every day!

Try MIUI.us!
Miui is using cyanogenmod kernel and base over which it gives great launcher and best default sms and phone apps.
Firewall and white/black list call blockers are included also.
If you can live with english locale, of course.

Thank you guys, yes i will try Oxygen and MIUI later on, but now im testing with CM7 and i have this battery percentage problem. If anyone has a solution to this, will be very much appreciated.
And another thing, should i update my Radio ? i have 4.08.00 something, is it safe to do so or might i brick my phone ?

[Q] HELP!! S-off device has battery drainage problems due to Android OS

Hi there,
so i gotta HTC one x last week, my first android..and I've gotta say that so far im hugely disappointed.
The phone has been draining battery like crazy ever since I got it. I've been charging it more than I've been using it, while it runs for no more than 4 hours when fully charged and heats up quite quickly. The battery usage options shows that the battery is being used mostly by Android OS and Android systems (over 85% for the former).
My friend suggested that i install a custom rom because it might be that the OS is corrupt. I bought the phone brand new and it came packed with an ICS stock rom. In the recovery mod the phone states that it is an S-off, with a CID #111111.
So i flashed the phone last night and installed a Jelly Bean Bindroid rom but the problem still persists. The phone drains the battery even when on stand by.
The phone runs fine besides the battery running out way too quickly issue.
Could anyone please help me with deterring what the cause of this problem might be and if the S-off thing has anything to do with it? and if so, how can I solve this battery problem? could it be a hardware issue?
Please help me. Im a NOOB at this!!!
Thank you in advance.

Might be a faulty battery. Look for a replacement OEM battery.

Check task manager too see which apps are running. Disable background sync if it's enabled, delete htc sense account if you have added it in account settings (it's a real battery hog).
Also, try to charge the phone to 100% battery 2-3 times and then check the battery performance.

Use BetterBatteryStats (search on here for the apk and instructions on how to use it).
Or, factory reset.
