is my battery drain normal?

hello, i just tried this tuto
http://forum.xda-developers.com/showthread.php?t=755903&page=4
but could not do it several times as described in the tutorial...
i charged the desire while it was on until the led light turns green... then i powered it off and charged it.. the led light became green after only a few minutes... so i powered it on.. and then switched if off.. put the charger but led light remained green.... so couldn't repeat it several times as described in the tutorial...
then i started using it... i lost like 1% every 1.5-2 mins of internet browsing... is that normal??
playing games like super mario on tigergba for 1 minutes drains like 1% of my battery..
is that all normal? so overall after 10-15mins of use (internet and gaming) i lost like 9% to 10% of battery... normal?

YMMV depending on conditions like what software your using, what's running in the background, live wallpapers, updating widgets and radios... Can't really say whats normal, my phone lasts about 2 days with just Bluetooth (car), three email accounts downloading every 5-15 mins and a few other things. Either carry a spare batt or change your usage.

no live background and wifi always on... that's it.. i am not even put a sim card on it yet... so not using gsm..

Is the phone/batt new? May take a while for it to reach full capacity... Also, you could try re-calibrating the batt through AmonRa.

what is Amonra? i have put my sim card on it... yes the phone and batt are new. have used it a couple of days now(about 8-9 charges in all now) and i lose 4% of batt after 2hrs and 07mins of phone on (and about 21mins of wake time)... without doing nothing... only standby.. everything turned off, wifi, bluetooth, everything.. i just want to know if the battery consumption is normal?
p.s. i also have a static wallpaper and my brightness is about 10%
4% of battery consumption in 2hrs of standby seems ok right?

To check ur battery usage, put a sim card in it and leave it in idle (Wifi off, data off and auto sync off) and No call/sms.. just locked and idle and you should lose only 1% per hour... if you are losing more like 3-4% every hour, then some process running in the background is using up the battery..
Use this as a measure to check your battery drain.. It always works for me

yes i Tink the battery is the cause

ok so 2% par hour is too much? i have everything off with low brightness and no live wallpaper.. i have advanced task killer and task xp and swipe panel running in background... maybe they are the cause?
update:
up time : 4:24:50
awake time : 0:29:05
battery : 95%
have done nothing apart just look at my contacts, navigate through menus and browse image gallery
The battery consumption seems right for me but i not really sure as it's my first smartphone

2% is not abnormal. 1.5% per hour is alright.... What rom are you using and have you overclocked with setcpu??
Edit: and a small advise.. Dont use task killers to kill off apps. Let them be. Just exit from an app using the back key. Use task killer only in an extreme case where an app hangs up. Otherwise android will take care of apps just fine.
and enjoy your smartphone... I try to use it maximum and charge every morning.. it is a beautiful device

If you use advanced task killer that could be an explaination for higher batterie drain. If you use android 2.2 or above then you don't need it.
Also do you have amoled? If you have a white screen showing on your phone your batterie drain is much higher then with darker colours.

ok thx for the advice. i am on stock froyo. I have set auto kill on advanced task killer.. i should disable it? and any good app to switch between apps? i am using task xp.
update : 5h45mins of standby and 6% of battery drained. about 1% per hour.. hence i think it's normal thx the advice anyway

[Q] Battery drained over night!

I have a problem with latest version of Android Revolution HD 6.1.0.
Yesterday afternoon I fully charged my phone and used it only a little bit until I went to bed and turned the phone off.
Today when I turned my phone on again (fastboot) I was shocked: Battery was at 25%.
How can the battery drain that fast over night while turned off?
I am using the correct Radio (12.62.60.27_26.13.04.19_M), Superwiped before flashing new version of ARHD and also cleaned battery stats when it was fully charged.
Can you please help me finding out what is causing this?

I´m not getting that much battery life out of my HTC Desire HD either when running ARHD 6.1.0 ... Is there any RADIO that could help?

Weird - I have similar problem with 6.1 Revolution.
Battery seems fine all day, put it on my bedside table last night at over 80% battery...woke up this morning with 2% battery left!!
really weird.

I'm gonna download Current Widget now and enable the log option and see what is happening in the log overnight.
Post the log up then and see if someone can take a look.

Any news about this? I feel that mine is dropping rather fast aswell..
Saturday i installed 6.1, installed applications and used the phone.. At a total screen was on for 4 hours... After a total of 5 hours, the phone was down to 15% battery...
Does application installation take that much or is something not quite right? I feel that i had more batterytime with 5.2.4..
Now i can basically see the battery values dropping while using the phone.. I have current widget and sometimes when i start the screen and go to home screen it says way above 500mA, is this right?

Well i don't have any issues, while using ARHD 6.1 with the recommended Radio

How have you managed to have Display use up so little battery?
Mine always has about 75% and up, at the least...

I use Autobrightness with no Mod for lower Autobrightness.
I have nothing changed.
Flashed recommended Radio.
Flashed ARHD 6.1.
Done.
As you can see some harder Battery drops, while i was playing some Games. All time WLAN on. But i used it als always and had a very nice Battery expand.

Hmm, How much time is your display turned on? as i said, this saturday after i had flashed i emptied the battery in about 5 hours with screen on 4 of those.. Feels like the screen is taking alot of battery but i guess.. I had full brightness, not auto..

I don't know exactly but i would say display was active vor 15h+.
Autosync runs every 3h.
If you freshly flashed, it will take some time to stabilize. So maybe drain it until its empty/almost empty(10%) then get a full charge. Try to reboot and watch again. If you still have problems you schould install current widget and let i generate log. where you can see how much it drain if display is off and/or phone is standby.
If I put on screen from standby and check current widget i have 3mA/5mA. So if display is off the drain is very low.

[Q] Battery Issue - Quick drop of percentage, then stays at 1%

Hello,
I have a very annoying issue with my battery percentage. Typical scenario:
I unplug my phone at 100% after loading it overnight and perform some basic tasks, like for example reading news with Flipboard for a couple of minutes. My percentage already goes down to about 75% to 82% in about 10 minutes. Then I don't use it intensively, only to check the time or messages, so the percentage stays at almost the same amount for hours. When gaming, or performing other more intensive tasks, my percentage almost drops 1 to 2 percent/minute. I get "battery low" warnings at 14% and 4% and then it goes down all the way to 1%. Now I can just continue using my phone like before, for example for gaming, web browsing, for something between 40 minutes and 3 hours.
The issue is obvious: my battery percentage is not calibrated correctly. This has been occuring since more than half a year now. I had many different roms over the years, I can't blame it on one particular one.
Now, I read about a lot of ways to calibrate your phone, so the percentage is accurate again. I have tried a lot one of them. None had any effect. I tried the following:
- wiping battery stats (multiple times)
- completely unloading my phone (restarting it multiple times, boot into bootloader and waited until it just turned off by itself and won't turn on again) and then reloading it (via charger) without interruptions (everything multiple times)
- using the app "Battery Calibration" (deleting batterystats.bin)
- using the app "Battery Monitor Widget" (waited until it shows 0 mAh, then wiping battery stats
- some battery saver app
I also switched batteries with a phone that was purchased at almost the same date as mine (09/2011) and has not been modded in any way. My phone currently runs Jellytime 4.2 R11. I updated it this week, and also wiped battery stats during the installation process at 100% charge.
Any suggestions? Any help is appreciated! Thank you in advance

Can you specify which ROM ur using?? Seeing your Post it doesnt seem to be ROM problem might be battery Issue too...Check it by charging it to 100% and Let it discharge to 0% and see the TIME...Flash The ROM which according to you had a excellent battery life and charge it to 100% and let it Discharge to 0% and compare the time if its Same or near then its battery issue you have to replace with new one else ROM issue...
I Hope this helps you...

Wechat nd fb are the top battery killers... logging out is no option.. btr to uninstall them

download cpu z and check what it says about the battery health, maybe battery is demaged. but it could as well be a system bug maybe...

i wouldn't recommend to try modifieng the phone cause the battery can be faulty if it's really new and you'd just loose your warranty. so just maybe give it back to service. my charger was also demaged from the beginning.

i remember something specific case in both times it shut off, well when i charged and then turned on google playstore and alotta other bunch of samsung apps updated and this time too after turning on it had update for hangouts and instagram, so is it notification and update related ?

well, updates use more battery but the battery should withstand it to some degree. like i said it could be maybe the battery or system bug. but i assume it's the battery

Hmmm....i doubted the same too.. btw is it cause of NFC in my battery ? but you gotta understand its a brand new phone

Try Battery Life Repair from playstore to check your battery
