Battery Calibration question - G2 and Desire Z Q&A, Help & Troubleshooting

On the "Battery Calibration" app it says in the instructions that it should be done when flashing a new rom. But I'm wondering if that really matters, I flashed cm7 bout 2 weeks ago. can someone tell me if that matters??

Whenever you flash a new ROM, your battery stats file gets deleted so, it normally takes a few days of battery cycles for the battery stats to level off properly, unless you delete the file again when at 100%.
There's really no need for this app, unless you have the room for it, as most recoveries have a means to delete battery stats (or you can just do it manually via the terminal).

What apps were running?
Have you tried installing current widget to see what is exactly happening, or how much voltage is going through your phone, even though it's sleeping? (ie, screen off)
I have not tried yet

This happened to me a few times (with almost no apps running) on RC7. Updating to 2.01 seems to have fixed that for me.
If that doesn't help, try using a different kernel and/or a different radio version and see if that works for you (we're reduced to experimentation as nobody has ben able to determine what exactly causes this issue).
I'm well impressed with mine. I went to bed with it fully charged, used it a bit in bed, always play a game and check the forums. Not plugged in at all and woke up this morning and its still fully charged!!
Amazing, since I have yahoo messenger running always. Been using it a lot since I woke up and now on 96% but I know its mainly the screen that uses a lot.
Brilliant ROM tbh
See if this helps:

well it's not really going to save your battery life, it just lets you see when/how the battery is being used up
Yes we can atleast know what apps are eating our battery.

[Q] New desire user... please help me!

Hi, i'm a new desire user coming from wildfire.
The development of desire is very new to me so I need some help with it.. When i bought my desire it was already rooted by the previous owner, so how do I tell which HBOOT version mine is, the CM7 one or the stock one. Next, I was wondering if there was any battery mod that's free similiar to the CirclesMod by Hoolm. Lastly, is it very normal for the battery usage to be about 80% on screen and eveything else under 9% when you check about phone>Battery?
Please help me, thanks in advance~!
1st question. Turn phone off. Restart phone with volume down held and power on. Post everything the screen says.
The screen does usually chew up most of the battery

On my bootloader screen,
Bravo pvt3 ship s-on
Hboot 0.93.0001
So what's this?
And the battery drains so fast that I have to recharge after using 6-6 hours .. I tried calibrated but no difference.
Sent from my HTC Desire using xda premium
as you are s ON you are on stock one... For battery mod try uot kitchen... Battery drain can be rom related... or Heavy usage?
I'm using stock rooted Rom so I doubt the battery is caused by the Rom.. is it better to use this mod that you recommend or flash a undervolted mod that is provided on the Rooted stock Rom thread page?
And thanks everyone for the advices so far, really appreciate it!

Hi i always go for under-volt as battery is better... so have a look in development which ROM you like.... at the moment im using cool3d sense aces s from coolexe... few modification posted by the other from the thread on top of that...
or try to flash new kernel from snq or bananacakes... they allow you to overclock and undervolt... MAKE BACK UP BEFORE FLASHING
Ok I shall take a look at the various kernels available. I have another problem now, whenever I charge my desire, it will never reach 100%, and only 99% as the maximum. I have calibrated the battery so I'm unsure why do I have this problem..

The one where i tried to charge it till full when powered off then wipe battery stats
99% is a normal issue (from personal experience).
Very rarely, I get it at 98%.
The trick is to unplug your charger, let it sit for a little while (let the percentage go down by 1 or 2) then recharge it. I also recommend you use an AC charger for this as I have found that I usually get this "problem" when charging from a computer.
I managed to solve this 99% glitch by reflashing the entire Rom... So its working fine now.
I was thinking of flashing other roms but seems they require partition of SD card.. I don't have a usb card reader so how can I partition it then?
Sorry I think I have never ending questions..

You can partition your card in recovery also

Which recovery? I'm using clockworkmod recovery. Is it able to do so?
Sent from my HTC Desire using xda premium
In clockworkmod recovery 5.0.2.0 it is possible, but i guess older versions also should be able to do it also...
But i know for a fact that version 2.5.X.X can't, so if you are using so old version, then you can't...
Flash the latest recovery...

Have you tried re-calibrating your battery?
Yeah dear I have tried but battery celebration apps required 100% charging for celebration.. but my device has always showing under 60% charging that's why its not works..

If u know any other idea for battery calibration so kindly tell me, will really thankful
Sent from my HTC Wildfire using xda app-developers app
Is it in your status bar that it shows the incorrect value?
Try going to Settings > About Phone > Status
It should tell you the correct value there. If it still shows up as the incorrect value i believe it could be a problem with your actual battery.

In your case, you don't need an app for calibration. Since you can't get your phone to show correct status, reboot into Recovery, go to Advanced and Wipe Battery Stats. Reboot phone, Run Wifi, Bluetooth, Torch, Music and anything that could drain battery faster altogether until the battery runs down and switches itsef off. Try recharging and see the result.
Hope it helps.
Cheers.
Thank u so much to all of u..

i have been experiencing the same problem with the battery .. doesn't seem to get past the 70% mark. I started noticing this few weeks into using CM7 ( currently using CM7.2 RC3 http://forum.xda-developers.com/showthread.php?t=1698029 the issue still remains) At first i found out that if i reboot my phone after putting it to charge , it would charge all the way to 100 %. But slowly that too started fading and now nothing i do gets it above 70%. even got a new battery to no avail, and i cant get more than 5 to 6 hrs with the battery .. the battery drain is incredible
am i using an incorrect kernel or something ?? any help is appreciated .. thanks in advance !
My opinion is its something to do with your phone itself, if it was software/kernel related we would all most likely get the same problem as we are all using the same piece of software.
Sent from my GT-I9100 using xda premium
I too have this problem mine does not charge beyond 79% sometimes 75%. With my experience this is too do with the kernel that CM7 uses. If I restart the device it will show 100%.
If I go back to the stock kernel the charging goes all the way to 100%.
Either my charger has broken or its the overclock-able kernel.
I have tried every other method out there.
The battery performance is good BTW.

Desire boiling hot!

Hi,

Ive also checked another pocket which contained Galaxy Ace. It was opened too but cold. Ive also got something before: google acct removed from the phone but i didnt touch it, camera went black and rom toolbox's verification failed. Does anyone know what are the possible causes and how to fix? have to take battery off. ManU kernel with Aosp gingerbread

In your signature is written that you use LeeDroid Sense rom. If it's like that you shouldn't use Manu's kernel cause it's made for AOSP roms, maybe that's the problem.

you could also try an app called watchdoglite
it alerts you when a certain app uses processing power above a certain threshold.

Why is my battery showing this?

My phone was working fine, but now this is my battery usage. I have restarted twice and it still shows like this.
Plus my CPU has been running for 248 days or something.

The battery is showing android os as 100% off my battery usage.

Alright, I'm a noob, I was with you up to reboot your device. "Go to recover and delete battery stats" was where you lost me. Maybe some more detail or a hint on where I can look to learn about it would be super helpful. Thanks.

Are you rooted at all? Installed any custom recovery? i.e. CWM or TWRP. You need to have installed a custom recovery to delete battery stats.
As for the android OS usage, that's very weird. Try searching it up on google and see if any results pop up. You could delete battery stats but not sure if that'll help. If you'd like to know how though, let me know.
If u r rooted and dnt have a recovery, download a app called 'sdmaid' frm store, and u wil get an option of delete bat stats!

I had that happen to me when I first bought the phone. Was terrified I would have to return it. Just charge it to 100% and reset it. No reason to put it in recovery or anything. That fixed it for me.
