[Q] Mobile discharging without use, is this normal? - Desire HD Q&A, Help & Troubleshooting

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.

Kernel Advice

I have poor battery life on my desire, it barely lasts 7 hours. I have tried wiping battery stats etc, and have the screen brightness at 50%. I have read that some kernels can greatly improve battery life, is this true? If so, which would you recommend, and do I just flash it like I would a rom? I am using the latest miui.
Cheers,
Steve

They can but finding the underlying app causing the phone not to sleep would be what I'd be looking at. Remove all installed apps and add them 1 at a time and see how the battery goes

Yeah i've tried this, there's nothing draining the battery.
Not at all
Such battery drainage can only be induced by either heavy usage, or phone not being able to go to sleep.
The differences between kernels in custom roms are merely a shades since all of them are pretty much battery efficient. You won't miraculously jump from battery life of 7 hours to 30 hours. Concentrate on your apps or even better, third party Widgets.

Probably a hardware fault then - the OS on it's own with no apps installed shouldn't drain a battery that quickly. Did you also turn off the sync options to test that theory?
Personally sounds like a knackered battery/phone
If it isn't apps/widgets (they are the culprit for heavy usage) then it would prob be a faulty battery. I did a little test last month to see how much battery I could lose in 24 hours. I lost 8%. I guess it could be a baseline to start off with.

Battery life-desire 88% display!

Hey guys how is everyone? Just a quick one...
In the past 12 months I've had my desire I'm shocked at how short my fone battery lasts. I can barely get 8 hours off the phone without a recharge. The phone sometimes switches off as soon as it gets to 15%. I've tried to calibrate the battery, wiping battery stats but all to no avail. Just this morning I've had the phone on for 1hour 10mins. From a full overnight charge its already at 64%. Battery use always shows the display to be using atleast 70%! I'm on the old amoled desires. Anything I can do peeps? Cheers
What's the total time of battery?

NB. Currently using android oxygen 2.3.3. Noticed no difference in any of the default htc roms I've used.
Been on 1hr 20mins and its shed 40%. I can try and take a screenshot for you guys

That sounds about normal to me, it sucks, get used to it or use your phone less. sorry.
Also forgot to mention screen brightness generally between 30-50%. Cheers folks

You probably messed up your battery with all that "calibrating". Unless your standby usage is significantly more than 10mA there isn't much you can do.
I had the same problem with oxygen. My fix was to unpartition my SD card. So no ap2sd. I use the hboot for different. I easily get 24 hrs with heavy data and video use.
May need a fresh install.

Excessive Battery Drain

My Desire Z has been a battery killer recently. I have tried different radios and roms and it still sucks excessive power. Even on Airplane mode battery monitor widget was giving ~50mah per hour drain with the screen off.
I have both a stock battery and a Mugen 1800ma battery and this seems excessive. I checked and there were no applications keeping the phone awake either. At work with minimal usage my phone easily drains over 30% of the Mugen battery. Signal isn't a problem either because I work 280 metres away from a Bell cell tower and have full signal at work all the time. I'm starting to think that something is wrong with my phone.

I had a similar problem with a stock battery of mine and ended up recalling it with my phone provider and they shipped me a new one. They (T-Mobile) said "not all batteries were created equal" and that sometimes even without water-damage, certain batteries lose their shelf-life much faster than others.
Since you're telling us that both your stock and your after-market are draining at a near equal pace regardless, this might be an indicator that it isn't your battery.
I had to return my original G2 to T-Mobile because of hardware malfunctioning in several areas, namely the audio mechanisms. If you're using a relatively new phone, and/or a refurbished phone, I wouldn't be surprised if you are experiencing similar problems.
Omg, recently, mines been really bad too. Trying to get to the bottom of it.

I'm starting to suspect a hardware problem on mine. I don't overclock at all. I've tried different roms, kernels and radios and it hasn't helped...

I had fast battery drain too, I switched to the ROM in this thread, and battery life is now AMAZING
use SuperWipeG2(+) and Guhl's EFS GPS fix available here before flashing G-lite
Have you tried calibrating? Charging to full, wiping batt stats, discharging/charging back to full uninterrupted? The link below is a great calibration tool.... very convenient. I wipe stats after every ROM flash and keep an eye on CPU/RAM usage with Watchdog lite. Battery life is always good.

how long does the battery last for aprox in standby and with regular use. if it dies faster then 3days on standby or less then a day with regular use there may be an issue im just wanting to know the time span of your battery....
also i had hardware issues with the g2 too. my radio sucked balls, i couldnt even keep signal in a call longer then 3 seconds and my wifi would just cut out for periods of hours at a time... im wondering if the manufacturing is becoming sloppy and they might be lacking quality control. i admit there is a lot to the phone but simple things like battery quality and signal quality should be checked regularly.
with the g2 i frequently hear things like this, battery, screen failures or behind the screen cracks, unresponsive touch screen and black spots, bad radio signals, color leakage and most commonly issues with the keyboard.

Well if battery monitor widget is correct my phone would last 26 hours in airplane mode (36 with my mugen battery) with the screen off (I tested this with almost every user app uninstalled)
Edit:
Considering there was a guy who left his old Hero with CM7 in airplane mode and that it lasted for 30 days before the battery died... I find this quite discouraging

Wow. Battery monitor widget is INCREDIBLY innacurate while in airplane mode. I left my phone in it for a good 10 hours and it was still at 100%
Disregard this post... and thread

Guys please help!

Okay, I am having a very frustrating problem that I did not originally have. My phone can last me half the day!! It is very frustrating to have my phone turn off on me everyday at 5 pm ..I love this phone but this is unbearable, especially considering that this is with very, very, very minimal use. If I actually use it the phone intensely, it will drain completely in 1.5 hours. ..It was not this bad a couple of months ago.
I have bullet kernel, and stock GB rom (2.3.5)
I had it always used it on "lag free" setting OC to 1.6 but I changed it to conservative mode to try and see if that would help and it didn't. I even used the core sleeper script from the developer's section and that didn't help either. I had changed radios a number of times when I was tinkering with custom ICS roms. I got my gf this phone a few weeks ago and put the same setup on the phone and she is getting the same battery life. I bought it used.
Does anyone have any suggestions!?? ...I would really appreciate it
You can extend battery life anumber of ways.. Tell me what Is on bt by wifi sync the screen ways ths most energy so turn that down as low a you can... Sounds like you are on an old ROM ...prolly eagles blood?
I suggest digital warfare 2.7 if you are on TMobile. Great battery life. Also flash your radio before your ROM and make sure you are flashing over a clean slate.

I am running on the Stock ROM with android 2.3.5
I am running off a nandroid backup I had restored after having an ICS rom on the phone for a few days. I used darkside superwipe, then flashed radio, then restored the ROM backup.
I always keep GPS, wifi and bluetooth off when I am not using them. I keep wifi on if I know I will be home for the day so I can use that instead of 4G ...I keep my brightness on the lowest setting.
Even with the sleeper core script, turning off 1 core, its still drains out at over 7% per hour without ever even touching the phone. Something is definitely wrong because I read people on the Sleeper Core thread saying they lost 3% in about 6 hours of standby with the script running.
the battery really should be in good condition because the phone is less than 8 months old and I frequently switch between a backup battery (cheap eBay battery), so that should preserve the original a little and even w/o the 2nd battery, the battery shouldn't need replacement this soon.
Have you tried using an app like Badass Battery Monitor to check what's app or process is eating up your battery?
Also, does your spare battery die quickly as well?

No, I haven't used a 3rd party battery monitor app, I just look at the system menu section that tells me what things are using battery and it is says my screen is using 50% ...my spare battery dies very very quickly. But it always has died this quick since the day I bought it because it is a crappy Chinese battery from eBay that I bought for $4 ...the first few times I used it, it would last about half as long as my original samsung battery
You should try to forget about the extra battery... and charge your phone while off then after ten or more mins of it being fully charged unplug then wait and plug back in to charger... It will likely charge again for a minute... Do that little cycle to get a full charge. After i do that i enter CWM and reset batty stats. There is more on this if you google it.

[Q] One X Battery Re-Calibration

Hi XDA,
I am pretty noob at forum posting so no hate
As we all know, the One X does not have a great battery, but, it enough to get a whole day, recently my battery starting playing up, Id have 20% left, and it would just keep turning off, as if it had no battery, I full charge it, and that seem to not occur again, Id listen to music for 20 minutes and Id loose about 8% charge, Im not using headphones, just earphones, now, im loosing 15-20% battery, id also loose battery with it in sleep, firstly I tried to wipe battery stats in CWM, and I loose 2% just from that!
All of that within a week, except for the 20% turn off thing.
It also seems to be a little warm around the camera, and a bit more below the camera.
Ive tried recalibrating using Battery Recalibration (https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en)
Ive tried full charging after a full drain.
Nothing seems to be working.
Im running:
Rom - Viper 3.3.4
Kernel - The Viper Provided boot.img
Hboot - 1.36.0000
Any help is much appreciated
Ill provide what ever you want to see (screenshots etc)
Thanks
Re-calibrating battery doesn't do anything for battery life. It's a myth. Read up on that. Maybe your battery has become old, or overheated at some point and is now malfunctioning. Too much heat is bad for batteries and overheating has killed one of my Desire HD batteries too. They expand at the middle and also lose their capacity quite a bit i.e. they discharge faster.

Okay, That might be the issue, Thanks
Full Draining your battery is a bad idea..
As the One X has a Lithium Ion battery
and they dont like to be discharged very low
