[Q] Mobile discharging without use, is this normal?

During the night my phone over a period of 6 hours, lost 3% without using any battery, with wifi, gps, data synchronization and automatic everything off. This autonomy is normal? For other devices I had, like the Galaxy and S remained the same with no loss of load in the same situation.
I'm using the rom CoreDroid 6.6, kernel 3.1.2 and Lee 12.54.60.25U_26.09.04.11_M2 Radio.
I thank you all.

It's normal, as long as the phone is is on you will lose some charge. Only 3% might be considered quite good actually.

If I change rom or kernel I get improvements?

As I said, 3% is quite good so there's not much room for improvement. The phone can't be on without using any power.

I understand, but as informed, on other devices, I have not had any loss at night, as was the case with Samsung S Galaxy, and got change for this new rom in your case and discharge the battery of your device in the same situation?

Well the SGS is a different phone. The DHD is a more powerful phone and thus uses more battery. The battery capacity isn't the greatest either (1230mAh) and thus it will lose charge faster. 3% drop in 6 hours is nothing to worry about.

Hawks556 Okay, thank you for the information, I'm certainly more relaxed in knowing that this is normal, anyway I will test other rom and kernel and then post the results here.

Allright, but remember to calibrate the battery everytime you flash a new rom and let the rom/kernel settle for a couple of complete battery cycles before comparing.

[Q] Weird CyanogenMod (nightly) Battery Usage stats.

I have a desire z and I am using a recent nightly and loving it but I have one concern my battery usage stats are like these:
After Charging and letting it go standby at night:
When I woke up after 7 hours battery was %89.
Usage was: Cell standby : %46
Phone Idle : %41
Display: %7
Wi-Fi : %5
Now you may tell me it is normal to have only cell standby if I let it go standby but even if I use a lot of gps and google maps for around an hour maybe it still show a lot of cell standby. And when I am using the phone I feel like it drains the battery a lot.
Are these stats normal. I remeber on my stock rom My display was always eating the battery like %40 %50 ish now display never shows above %10 even if I use the phone a lot!
Is this because of radio? Should I try different radios? I had radio that came with downgrade of my Desire Z and than I flashed the neww Bell radio.
Please help cause I am not sure if this is normal.

Noone ? any idea?

I'm on CM7 #186 since Sunday and my battery's live is slightly higher than with stock Gingerbread.
I recommend that you install "Battery Monitor Widget". It uses a lot of RAM, but it has some pretty good statistics what's using the battery.
About the display: I think in stock the battery display stats are wrong. Mine had always 70%. On CM7 it's 7% right now after two working days and moderate news in the evening. Phone idle is 43% right now.

Probably the display usage is wrong on stock rom but i am not really sure. I will try that app you recommend thx.
So my stats arent that weird.

[Q] Weird HTC Wildfire Battery Meter Issue

ROM : Cyanogenmod 7.1.0.1 Android 2.3.7 <<< Doubt this is important
Kernel: 2.6.35.14-nFinity [email protected] #1 <<< Might be important
S-ON
Okay so my Battery meter is definitely acting up. After charging the battery overnight it only charges to about 89%, maybe 91% if I'm lucky.
If I unplug and immediately reboot the device the battery meter says 98% or 97% at startup. Right now I have a reboot scheduler app that restarts my phone every morning at 4AM so that it's accurate-ish in the morning.
But that's not the only issue...
When I use my phone during the day, maybe making a call or two, on a 2G network to save battery, no Wifi or Bluetooth use and phone not overclocked, my battery drains incredibly fast. It goes down 15%-20% per hour! By about 3PM the phone says 15% left and then slowly drains down to 3% battery life. This is when it gets real weird... The battery level stays on 3% for about 6-8 hours, then finally goes to 2,1 and then dies. I got 3.5-4 hours on 3% with max overclock (768mhz on performance setting), maximum brightness, screen doesn't turn off, playing music while on HSDPA network, bluetooth on... So the battery doesn't seem to be the problem, only the battery reading that is displayed.
I tried going back to the default software that came with the phone, Android 2.1 with Sense and original kernel. The battery drain was a little slower but same effect, staying forever on 3%.
Can someone please explain to me why the phone does this? It's not a trainsmash, at least the phone isn't really draining as fast as it looks, but I effectively have no idea how much time the battery has left, which isn't ideal. It still lasts me the day and I charge it every night but I'd like to have this solved, it wasn't always like this. The phone is now 10 months old.
Any help at all will be greatly appreciated.

Defective "chipset"? (This i what HTC says, not me)

I sent in my Wildfire for repair. Got it back and it's not the chipset.
Its something to do with clockwork or Cyanogen.
The battery was fine until I re-flashed them.
Now it's back to the same ****ty battery life before I sent it.
Soon as I get home. I am going to flash a new rom. Possibly an older clockwork and flash a new radio.
Will post results.

If you notice the first thread, people who have never rooted/modded are also experiencing this. But, in either case, do post your results.

True, but in my case I know the problem to an extent.
I remember now that the battery starting acting up after updating to newest Clockwork recovery.
So I will flash that first. Run tests.
Flash Radio. Run tests.
Flash Rom (non-cyanogen). Run tests.
I shall do tests 1 day at a time maybe if tests prove a posotive results then I will do 2 on the same day.

Don't forget to re-calibrate the battery before your tests. It's a major cause of battery drain on Custom ROMs.

Ah, yes. Almost forgot :3

Battery drains so fast

My battery seems to drain very fast.
The phone is brand new, and I'm not able of getting more than 12 hours with one charge.
I'm using lowest brightness possible, wifi ON only when needed, 3G on only when needed (The rest of the time it stands connected by EDGE, updating whatsapp and checking emails and twitts each 15 minutes), bluetooth off, gps off and autosync off.
When I'm sleeping it dischargues 3% per hour!
I have installeed juice defender, battery calibrator and battery graph.
Is this normal?
Any help?
Battery reaches 100% at 4,2V

Which Rom, kernel, etc do you use?
Sent from my HTC Desire using XDA

Thats not normal.
Maybe you should look for some apps installed, which dont let your phone fall into deep sleep....

I had an app once called android assistance r something like that and it killed my battery. I went to bed and battery was at 94% and when i woke it was at 2%. Unistalled straight away lol. And like matdroid says, what rom u using coz sense roms aint battery friendly.
Sent from my HTC Desire

I have been testing with differents roms.
That test was done using stock 2.2 rom . Could it make that big difference?
Have installed leedroid, oxygen, sandvold 0.8 and CM7 RC2.. But haven't had time to test them properly. I hope the reason of this battery drain is the ROM .
The only program (I think) is running all the time is Whatsapp. And it works fine with EDGE. Twitter and emails are set to update each 15minutes thanks to JuiceDefender.

I`d recommend to try with a different battery, see if there is any difference.

U could also look into trying a different kernel, most roms these day come with a choice of a few kernels.

Here is the status of my battery.
Let me know if it's ok.
This was using Oxygen COS GB (17-04-2012 built)
It's in spanish (Pantalla) is screen and voz is voice.

Are you happy with that drain?

Obviusly I'm not happy. But what can I do? I have tried almost everything.
Please help.

Please post the time the display was on plus your brightness-setting.

Dear friends,
Here are the stats again,
This time it lasted more time because it included the time when I was sleeping.
See attached pictures.
The battery still drains fast.
Best regards.

I have also the same problem. Today it lasted for 8h.
I bought a new battery 2 weeks ago, so it can't be that. I've cleared battery stats with 4EXT Recovery and done also clean wipe when changed the rom to RSK 7.4.3.
Before that I had RevolutioN 4.0, but when i updated from 3.0 to 4.0, the battery problem started. I don't if it's just a coincidence. 3.0 worked perfectly, and it's a shame, that i haven't got this work ever since =7 "If it works, don't fix it"
On RSK, what i have now, i use snq kernel (installed the kernel on RSK installation).
//EDIT:
Oh yeah, and also done all the tweaking with Deamon Controller, like on the instructions what RSK wrote on first page.

My phone lasts 12 hour when I don't use massive data.
I tried different kernels and finally found that the ManU is the most battery friendly for me.
I don't use any optimization app, which I find quite useless, I just use two profiles in setcpu:
screen on: 1152 Mhz, governor performance
screen off: 422 Mhz, governor powersave
I prefer a more responsive phone than a longer battery life.

First, try to turn of data connection when you're not using it.
Then try to do this:
-use your phone until you drain the battery
-turn of the phone and connect it to charger and leave it to charge 10-12 hours
-disconnect the charger, turn on the phone and use it until the battery falls down for a few percents
-turn it off again, reconnect to charger and leave it to charge for about an hour
-disconnect, boot into recovery and wipe battery stats
-turn the phone one and use it, you should notice the difference.

I red that thread before and I know what you wanna say, but my point was first part with charging, not deleting battery stats. It just has some connection with the structure of Li-ion batteries. It is also recommended to completely discharge the battery and recharge it with the phone turned off once a month.

Thanks for your answers.
Screen is on a lot of time (in the screenshots I posted you can see).
But I use lowest brightness possible, between 10 and 20% when I'm indoors and only high values when the sun hits the screen.
pieru, can you post the ManU kernel link?
I don't know what kernel i'm using, i installed Oxyged cosed (I think last version) fropm roalex. How can I know?
Thanks nlooooo.

I'm fairly certain it uses thalamus kernel tho. Oxygen doesn't work with any other afaik.

Really desperate here...

My battery discharges pretty quickly and I just don't know what to do anymore...
It usually goes down pretty fast when I'm connected to wifi. I think the main culprit might be Kernel (Android OS). Please take a look at some screenshots I took while using the Gsam battery monitor app and Better Battery Stats app and correct me if I'm wrong.
I have stock ROM, stock Kernel and my Radio version is: 5.1204.167.31
What do you think I should do? Change the Kernel, Radio or maybe both?
And if so, what would version would you suggest for my stock ROM?
Or should I just replace the battery and hope that fixes the issue...

Wifi will definately drain it quicker, usually keep mine turned off until I use it. Depending on how old the phone is definately affects battery life, mine is now just over 2 years old and I find that although it charges to 100%, it will drop to 91% in the first 5 minutes of using it. HTC has a self test in the dialer enter *#*#3424#*#* then follow through to the battery test. I think phone needs to be in airplane mode and has to be fully charged, then leave it on for an extra hour or two. Test takes an hour and from memory if battery is above 70% it passes.

Mine does the same. It drops to 91% fairly quickly after charging. I did the HTC battery test about a month ago and it showed 81% battery left after the test (it said that if it's below 70% the battery might be faulty).
Since I made this thread, I managed to change the stock kernel and now I'm using Alex's kernel. The battery usage is much better but still the Android OS or kernel drains much of the battery.
Do you think changing the battery completely I might have better results?

Before Alex's kernel, I tried XM's latest kernel because I read on OP's thread that it works with stock ROM too, but I never managed to boot my phone after flashing it. (and I did everything right I think: cleared fastboot cache, fastboot flashed the boot.img then flashed the zip in recovery)
I am all for trying lyapota's kernel but the download links have been removed in the official thread I think. Can you provide me with a link for downloading please?

Thank you but I am already using Greenify.
Only one option left, to try and remove some bloatware stock apps and see if that changes anything.
