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).
Sent from my HTC Wildfire using XDA App

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.
Running for more than 2 days now. \m/

[Q] 1min+ boot times

I'm still learning but I know that 1min + boot times aren't normal. I'm running Synergy + God Mode.
I'm also noticing about 1% a min of battery drain. I'm assuming the drain is mostly from 2 source, 1) I'm in it debugging and exploring a lot more and 2) I'm noticing it more due to the accurate battery indicator.
But if there are any suggestions to tweak these I'd appreciate it,
Thanks again!!

Well its a big rom, and you figure 15-35 seconds at the splash screen, and maybe another 30 give or take, you can get a minute boot time, though the very first time it'll take longer cuz' it has to build the caches. Also I would recommend changing the kernel, or wiping the battery stats after the phone is charged to 100%.

yeah what he said ^^^ all the sense 3.0 roms take a while to boot and it is perfectly normal.

Thanks guys, which kernel would you recommend?

[Q] Battery lasts only only 6 hrs with WiFi, 10 hrs on standby.

My battery drains within 6 hrs of WiFi usage. No heavy downloading or updating, (keeping auto sync off).
With out WiFi, the phone lasts for hardly 10-12hrs. Mobile data seem to last longer than wifi.
I am charging for more than 10hrs to make sure battery is full and there be no calibration error.
The issue started happening after I installed Sunabh ROM. I use to wonder why there is a "switch of WiFi notification" in Sunabh ROM, every time there is no wifi connection established. Now I know why.
What could be done to solve the issue ?. I have tried other AOSP, stock based ROMs after that but couldn't solve the problem.
Please suggest methods changing kernel, radio or may be calibration methods.
P.S. I wonder, why there is still no standard guide to improve battery life in this forum . There must be certain a software set that would provide maximum battery life (assuming average hours of use).

Turn wifi off when the phone screen is turned off

I use the "SenseOnFire" rom and my wifi is on all the time, when i dont use the phone that much the battery lasts 36h or more. but i noticed when i use the 3g my battery drains faster.
P.S. I had your problem when i used JokerDROID 4.2, the exact same thing

Try this out....it will help you on your present rom..
1. Go to recovery and wipe battery stats.
2. Open market and search and install battery calibrator.
3. Plug on charging and charge it to 100% and then open battery calibration app and click on battery calibration while keeping the charger plugged
4.after when the app says calibration done..remove your charger plug..and you are ready to go.. but after this step..let it discharge it to 0% and then charge it to 100% without break.. hope it works for you.
This improved my battery life to about 4-5 hour..

The other thing you can do is try reflashing latest radio. Unless you don't have an a3335 phone. Also try entering *#*#4636#*#* then in phone information scroll down then in " set preffered network type to " GSM auto prl ". It will save some battery.

There seems to be a misdirection in the entire forum on how to improve the performance of the phone. I hope a senior member consolidates and prepares a "How to improve your phone" post rather than a list of all ROMs and other useless shopping lists.

Was that directed at me? Sorry, I am not at your beck and call here. and I am not obligated to do anything for you. Help yourself.

If you feel there is need for a "how to improve Your phone" thread then crack on and make one because (sarcasm) you're obviously smarter than us all, one thing you forgot though is that every phone is different, yes some things work for all but some don't so even a thread like this might still be redundant for you!
Most people on here post suggestions from there own experiences when trying to solve problems for themselves, they may be correct they may not, you should be thankful to these people even if they're suggestions weren't right for you. And as for the list of roms and the shopping list I bet that thread has helped thousands of people solve problems, which is a damn sight more than you've done in this forum so jog on mate!!

Why he mention "pratically"? Practically means just what you can practice. And our suggestions are practiced by us. It may/ may not work for you. But you should check it. And about the thread you mentioned, dude each of us have personal interests. So as we customize our phones. Its different for every one. What you can do is roam around the forum and take what suits you the best.

[Q] HTC Wildfire power problem

My HTC Wildfire often shutdown while I'm using my phone especially but not limited to browsing and visiting the Android Market.
When I reboot my phone after the random shutdown, my battery level drain out even the battery is full before the random shutdown. I then shutdown my phone and switch on it after a few minutes, the battery level came back to the initial level, i.e. 75%. And if I switch on with my phone plugged, It switch on with 100% battery level.
I first encounter this problem after I had installed Go Launcher EX on my phone. The problem continues after I uninstalled Go Launcher EX and using LauncherPro.
Now I had rooted my phone on CM7 and this shutdown still haunts me, please advice.

Do you use a cpu manager?
If not, please check settings/cyanogenmod settings/performance/cpu/ What does it say?

does it shutdown, or does the screen simply turn black, while the led lights, remain on?
to be honest here, it sounds a LOT like the power issues on the HTC Touch Pro2.
While that device ran Windows, as to android on your device, it seems like there might be a cross-os programming error on these devices.
could you also check if this mainly happens when you were suppose to receive an sms or incoming call, while also using the internet?
If so, i think i might know where to look for a root-cause of this problem.

It turns off completely. Most cause of the shutdowns are Internet browsing and visiting android market, no calls and messaging were made nor receive that time. However, the shutdown doesnt happen when I charge my phone. So is my battery faulty?

I found that when I overclocked my phone shut down and randomly rebooted. I had to drop it below 700 for it to be stable.

But this nightmare haunts me before I root my phone, and it doesn't reboot, just shutdown

Then it may be a hardware problem. If it was a software issue a new rom should have fixed it. Have you got a warrentee? You may have to use it, but remember you may have to flash stock and s-on again or they might not accept it.

I had already purchased a new battery online. Just waiting it to reach my door step and I will check whether my battery is faulty or not. Thanks

ok good luck

I had the same problem with the phone i used before my wildfire, it's a SonyEricsson, have no idea what's the problem either

Using go launcher at the moment and apart from random restarts I don't have a problem like this. But then again I haven't played with the CPU settings yet. Also I know I'm a newb but you could try recalibrating the battery if it's displaying false statuses

Done battery calibrating but then phone shutdown itself during the process, I think might be the battery causing it.
I asked the sales person in a HTC store regarding this, might be hardware or faulty battery

I'm having exactly same issue. Did you solve it replacing the battery?

The problem solved!!
Yes, replacing the battery really does solve the problem
Below is the link to the battery I purchased. It's a third party extended battery with additional 200 mAh compared to the stock battery.

I don't know if a calibration would be able to solve your problem. I.e letting your battery be completely drained and recharge it to 100% while it's turned off, and do it again 2-3 times.

[Q] Battery drain on CM7.2

Hi all,
I am using CM7.2(FXP106) on my Xperia arc, with the kernel that comes with it. But I find out that battery drain is much more worse than the stock. 42 ROM. I usually charge the phone to 100% before I sleep, and the phone only uses 3% during my sleep with stock ROM. (stock kernel, cpu is downclocked to 768MHz when screen is off, using conservative governor.) However with CM7.2 my phone consumes more than 10% during my sleep. I also downclock the cpu to 768MHz when screen is off the cpu governor is smartassv2. In battery usage, mobile standby and phone idle consume the most. lol (It used to be display with stock rom) Is there any possible workaround? thanks a lot.
Ivan

ok, i try to give you a view points to check:
read and install this on your phone. I had also a battery-drainer on my phone. i found it and now i´m happy
One time, on my x10miniPro the facebook app drain my battery.
Have you clear dalvik-cache before you install the rom? full wipe?
I installed many custom-roms at my x10 miniPro. Sometimes i have also fast battery drain. Then i made a second time a full wipe, clear dalvik cache and install the rom new. This fixed most of the problems.
try this and report

I had the same issue, but they closed the Issue at the project-page:
http://code.google.com/p/freexperia...tatus Priority Milestone Owner Summary&id=155
for this reason i changed to Arconium, and.... 1% during a whole night in flight mode, with FXP it was about 10%!
i really miss the additional settings from CM7 but as long as this Problem exists , even if they say its normal, i wont switch back.

I had exactly the same problem whith CM7.2 FXP107
It was "Cell standby" (I'm not sure it's how it's called in english) that was anormally draining battery. It may be linked to baseband (I was using 64 one).
I had wiped everything possible before, flashed with CM7.2 kernel.
So I swiched to Arconium 7 + DoomKernel 0.18 + baseband 36 with patches. No problem since.
I don't know where the problem came from, it didn't took time to investigate, it was to much of a drain to keep my phone like this.

i also tried Baseband -36 and -56 no difference, Full Wipe Battery Calibration and so on, but nothing changed.

There is no excssive battery drain on CM7.
Flash latest kernel, try different basebands, calibrate the battery sometimes (correct calibration !) and you won't have battery drain anymore.

1. Download and install xRecovery from here.
2. Charge your phone to 100%
3. Turn off the phone and boot into recovery
4. In recovery, go to Advanced options --> Wipe Battery Stats --> Yes
5. Take the battery off
6. Insert the charger chord
7. Put the battery back and wait for the phone to boot
8. Once the phone boots up, you will notice that the battery percentage is around 88% instead of 100%
9. Charge the phone back to 100%
10. Repeat 4-5 times, seems to be the sweet spot
11. Enjoy your hopefully better battery life and report!

Thx for the Guide , but this doesnt work for me, once i had 82% after the first reboot , but now my phone doesnt boot automatically when i re insert the Battery, there is just a charging Symbol. when i boot manually , i have 100% battery.

You can use Toggle 2G with CM ROMs, pretty good in saving battery, you can set data to switch to 2G after certain minutes after the screen is off.
