50ma battery drain on stock and cm7

Hi wildfire users,
my girlfriend got her wildfire yesterday.
The first thing I've fine, was to root it and check the standby battery drain.
It was between 27 and 50ma in AIRPLANE mode, without sometimes at 120??
My device got 1-2 in airplane and 3-5 without.
Thought it would getting better after flashing cm7, took the rc1...not really.
Any suggestions? Iam an experienced android user, but my options are running out, what else I can do.
What I've done:
Checked drain with current widget,
checked partial wakelocks with spare parts-seems okay.
Uninstalled all custom user apps I had installed.
Read here, that reflashing the radio fixes some issues...didn't tried that yet.
Any other ideas?
What drainages do you've got?
Waiting for your answers.
Edit: perhaps it will help to let it charge it to 100% and check again...maybe let it also discharge one time ^^.¿?
....think i was perhaps a bit over motivated...

Battety drain will be above normal just after flashing a ROM. You need to make a full charge and then go to recovery and wipe the battery status.
Then do few complete charge-discharge cycles. Then it will be definitely better than stock rom. And use CPU settings in smart way. Work on the minimum setting and governor. Also depends on other factors like live wallpapers etc..,

How does calibration the battery prevent from it from draining faster ?.
Suggest some thing that makes sense.

Battery calibration gives accurate reading only, it will not improve the weared out battery.
When shifting between roms, the battery will not give accurate reading because not all roms utilize the battery in the same manner (Rom saves the details in batterystats.bin file). So, what if it gives wrong reading. There might be a possibility that it shows 100% even when not fully charged. So we think battery drains faster, but the fact is we haven't charged it fully. (correct me for any errors).

Yes showing 100% wrongly must be the only situation where battery calibration be blamed. But 8-10 hrs of charging from deep-down-zero should definitely make it full, right ?
Whats your general time taken for charging in standby mode (WiFi, Mobile Data, Bluetooth Off).
I am experiencing heavy battery drain with WiFi, since I installed Sunabh ROM. (He adds a switch off wifi notification to hide this fault. Cunning.)
Any solutions ? May be re-flash the radio or change the kernel ?

Dude, attack the CID bug.
I resolved my issue without even switching of my phone once, let alone flashing anything.

[Q] high battery drain on all roms!

Hi! Before i have got a drain of 3-6 mA with most of the roms, but suddenly all roms dain 16-20 mA. No matter if it is MIUI , cm7 or sense roms. They all have the same drain .. is my battery bad ?
Got my phone waterdamaged 2 weeks ago , but this bad battery time started yesterday...

First you need to calibrate the battery.
Charge your phone until Current Widget shows 0mA. Then go into recovery and delete battery stats. Let the phone discharge until it shuts down by itself, then charge until it is back to 0mA. That will calibrate the battery.
Secondly, new ROM's do take a few days to "learn" how to use the battery most efficiently so you wont get the best battery life instantly.

I know that ROM´s need a few days , but i have waited a few days ,and noticed that it is allways the same drain... But i will try calibrate my battery next

And please make sure that during the period of charging it the second time that you do not take it off the charger. That will mess up the calibration and you will have to start all over again.

you might want to try a new radio too

same for me. I tried everything I could.
I tried these roms:
-coredroid
-ARHD
-honey
-virtuous
-MIUI(current)
I tried these methods:
-multiple new recommended radio + ril
-battery calibration app + clear battery stats(recovery) @ 100%.
-full wipe 1.5
-re-root(hack kit v12.3)
-different kernels
When I first rooted my phone battery was perfect on any roms until I flashed ARHD,thats when my battery drainage happened.

how many hours you are getting now....with regular usage ????

I'm getting the same here... Started with ARDH too, then LeeDroid, now Virtuous.
Clean installs each time, apps restored using Titanium. Also re-flashed the recommended Radios too and calibrated the battery once.
Current drain is 15% / hour on Standby ~70+mA.
I noticed no unusal Wake Locks either.
I'm loving Virtuous, but thinking to go back to stock if the new Viruous update doesn't solve this.
Just whilst typing this I lost 2% :-(

Yeah this is no fun...

[Q]Battery acting weird

My phone was all fine, till i flashed Arco's CM10, then my phone started randomly switching off. When started, it showed 0% battery, which was weird as it was always properly charged.
Then i restored my CM9 backup, to check if it was a ROM bug, but I got the same error again.
Attached screenshot for battery stats. Battery problem or Software bug ? Anyone with same bug ?

After flashing the ROM, did you wipe battery stats? If not, that will probably be the cause of the weird readings......
Basically, over time, your phone would have calibrated the battery usage to your previous ROM....when you installed your new ROM (that has different battery usage patterns) your phone is still trying to apply the stats from the old ROM which is what is causing the problems.....wipe your battery stats then complete 3 or 4 full charge - full discharge cycles, and things *should* settle down....

Tried that...
But it gets weirder and weirder :/

Try the battery calibrator on the playstore.
If it still persist then the problem is in your battery.. suggest you change the battery with the new one
Pressing "Thanks" button will be much appreciated if user's posts useful for you

Or you can try this:
Clear battery stats via CWM. Turn off your phone, and charge it. Wait until the charge indicator shows up on screen. Then turn on your phone and leave it until it's full.
Sometimes when I get batt weird reading, that trick works for me.
In some occasion I found that offline charging and online charging shows different battery level.

when should i plug the cable if use ur trick?

Clear the battery stats first via cwm then turn off your phone after that you can plug in your charger.

Just like reddvilzz said above. After charge indicator shows up on screen, turn on your phone (but do not unplug the charge) and leave it until it's full.

[Q] Rom/Kernel issue OR Battery?

Hi all
After sitting with my stock SGS4 (i9505) for a few months I decided to root (as i had my N7000 and HTC Desire).
About the same time as this my phone began turning off seemingly randomly. At first i thought this may be a ROM/Kernel issue but I have tried a couple including Stock(rooted), Carbon and the GooglePlay Rom. The same thing happens for all of them.
Once off, the phone boots to splash screen then turns off. This cycles. I remove the battery and the phone will turn on, sometimes showing a SIGNIFICANT apparent drop in battery (90% reduces to 3% during this single on/off cycle). A quick charge and restart will often cause the rebooted phone to read the battery at 90% again.
The battery does appear slightly swollen and i'm curious if anyone could shed any light on:
1) does this seem a battery / firmware issue and
2) any suggestions?
Thanks in advance for any help you can offer!
Currently: GooglePlay Rom 4.2.2 PhilZTouch Recovery
Regards
Warnoceros

If you're saying the battery is "swollen" it probably is a battery issue IMO. Especially if you're having problems on every ROM you've tried.
Have you tried going back to stock to see if it's still happening?

Hi
Thanks for replying. I'm downloading stock now so will report in the morning.

Bad battery.

Hi,
So, went back to stock (binary counter has moved up unfortunately - didnt read into that before hand). Was still rebooting. Have replaced battery and this seems to have done the trick for the time being. I noticed that the unit did not reset until my google accout restored apps to the phone so there is still a chance it was a bad app i suppose.
Most likely the battery though
Thanks

Desire HD - charging only when phone is turned off.

Hi
I have a strange problem with my DHD.
Problem: not charging when phone is on, nothing happened, diode not lighting.
But when phone is off it is possible to charge the battery.
Problem is occurred on 2 batteries (unfortunately not original - one is Andida and another one is compatible from other HTC device) and on different ROMs.
Some time ago everything works perfect until something happened with battery status - it started showing wrong stats and the charging problem was appear.
Is there any solution?
And sorry for my bad English

If You install different ROMs - wipe battery stats.
