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] HTC DHD 4.2.2R8 drain battery so much

Hi everyone!
I'm using JellyTime 4.2.2R8 on my DHD.
It's working fast but battery drain so much.
Ex: I only view screen, scroll something. Everage 1 minute, battery degree 1-2%
Who can help optimize this problem?, thanks!

Hi,
I installed JellyTime R8 on Monday evening, and I haven't experienced such a battery drain so far, it goes down a bit faster than my stock Gingerbread+Sense ROM. I might have other stats issues (wrong "on battery" duration, charge stuck at 90%...), but no drain so far.
I am not well experienced in flashing ROMs and how to solve problems, but I have seen lots of people advising to flash the battery stats and recalibrate. But you need a few complete charge/discharge cycles to make it work properly. (But according to a few other people, it's a kind of religious belief too...)
You can also install a more precise battery stats app. I saw a more detailed message in Jellytime Dev thread (in one of the last pages). If I find it again, I let you know.

I cannot find again the thread/post where I saw this information, but the application some people advise to use is BetterBatteryStats.
To give you a counter example: since I flashed JellyTime R8 (Monday 20th Mai, 23h GMT+1), I fully charged my phone only twice.
The first discharge took almost a day (but I used it a lot, configuring and playing with the new features).
The second discharge started 33 hours ago and I still have 50% as we speak. Maybe the stats are wrong, but the phone is still ON after 33hours. I'll let you know how long it lasts.
I am on GSM roaming all day long, but my phone stays most of the time in standby mode.
A few things that I've done to optimize the battery life:
- remove the constant location-tracking, both GPS and 3G (especially as GPS is not working since I flashed JT R8);
- remove permanent/auto 3G connection, as I am spending all the day abroad, it is useless to keep 3G activated, without data roaming on.
Go in Settings/location and switch the toggle off.
Go in Settings, expand Wireless and Networks (Plus), then Mobile Networks and untick the first box (my ROM is in french so I am not 100% sure of the translation, it might be something like Activate Data)

Thanks Matth59 !
I toggled off some setting in phone (GPS, MobileData, effect screen, animation, turn off notification some app...)
But but it does not improve the problem of battery.
I charged full battery, after 24minutes
Saw status of battery on 24m19s, (95%)
Screen 70% (I set bright of screen about 20-30%)
Cell standby 6%
Android system 5%
Phone idle 5%
Wifi 3%
Facebook 3%
Android OS 2%
Media server 2%

And how long does it usually take for it to be discharged?
The second time I charged it, it said that charge was complete and stopped charging at 90%, and I got the impression that it reached that level quite fast. But the device is still on, after 38 hours.
I hope somebody with more experience in that field can give you a better advice or more information, than just flashing the battery stats and recalibrate it.

After one week of using R8, this is how battery is going for me.
On standby, it can last as long as it used to with the stock Sense + Gingerbread ROM (or even a bit more, but maybe because I haven't reinstalled all my apps).
When using the phone, battery life is going down quite fast, and I am not sure if it can last more than 1 day of normal use (3g, mails, messages, calls...).
The most battery consuming task is the screen. It makes me wonder if it could be related to the feature that was introduced by Google since JellyBean 4.1: Project Butter, which makes everything smooth in Android.

[Q] My Phone Radio is a battery hog.

Hello everyone.
I noticed something weird happening with my M8.
I changed my carrier last week, they gave me a new SIM Card.
I never had the issue when I was using the phone earlier. After I replaced the SIM Card with my new Card, I'm getting horrible battery drain. I attached a screenshot of my usage after a reboot.
That Radio was eating more battery than my screen. How's that possible ? My Note 3 barely consumes any battery on standby.
This one is sucking away all my power.
This is going crazy. I'm entering flight mode, as its losing 6-7 % overnight after a reboot.
I have everything disabled from sync, to google now, to "ok google". I'm on 0 brightness.
Can anyone suggest me something ? Any suggesstion/solutions are most welcome. Thanks in advance :good:

Honestly, that is not terrible standby. Tho a longer test would be more accurate.
Is location on? Have you disabled any HTC bloat?
Anyway, it's not that out of line really.
Best I normally get overnight is 0.4 percent drain per hour.... I'm rooted, debloated a lot of HTC stuff, location off and most other features.
I don't really see an issue.

Thanks for the reply. I switch everything off including sync, motion launch gestures, auto brightness and location has been completely disabled including google location reporting.
When I enter flight mode in the night with extreme power saver, I only lose like 2-3 % overnight, with everything disabled. However its not the same with the flight mode turned off. I lose like 5-6 %. I barely have any apps from the play store. I also found that using a different launcher saves the battery..
And when I use the phone for sometime, the screen dominates the radio consumption..
Finally, please have a look at the screenshot I've attached. I lost 10% battery with 30mins of screen being on. Is it normal ? Please tell me..

You must have rebooted. You used 6 percent with 30 minutes of screen time. Gsam stats reset when you reboot. So.... 6 percent drain with 30 minutes screen time is 8 hours plus screen with 100 percent gone. Lol
You are doing above average if you ask me.
Enjoy your device and stop worrying.

Yes, thanks for the reply. Probably I'm more concerned about the battery... . I should stop bothering about it

Battery Life - Idle drain?

I was wondering if anybody else had this issue or had any suggestions.
Battery life is normally great on the tablet, except every once and a while it gets stuck awake overnight. There doesn't seem to be a 3rd party app that is holding it awake, as Android system and OS is what's using most of the battery.
As you can see in the screenshot, Doze works fine and barely any better is drained, I used it briefly, came home from work and half the battery had been drained.
Thanks for the help

Not sure if it's normal but mine does the same.

I've seen a 30ish % drain sitting overnight a couple of times over the past 2 weeks. Can't seem to find a rhyme or reason for it.

I can't imagine it being "normal" since, with Wifi set to off while sleeping that the device should drain that much.
It's odd and happens randomly, I'm on the same page as you bluestang.

It happened to me once, at night it wastes a 15% battery.
I changed in wifi advance options to not maintain WiFi always awake, only in charge.

That's the setup I have though - so I get no notifications or anything when it's not on. Yet something is still keeping the device up.

I have *exactly* the same problem with an all new device, and with nothing but a game installed on it. After a reboot, if I let the Pixel C right there for a night, then it only drains ~3/4%.
Then I play the only game I have for 5 minutes, and let the device again for a night => it now wastes a 20% battery!
No idea what's going on... "Android OS" appears first in the list of app, but this does not help me so much to find what is actually happening...
The issue still appears even after a full reset of the system (I'v tried, without success).

Exactly. If I reboot the device and let it sit, doze works fine, the second I open an app, use it and put the tablet down, something hangs and keeps it awake. Always Android OS that is keeping it awake as well...

I have this issue too. Are you guys on xceed Kernel?
Whats really interesting even better battery stats Shows no culprit.

I'm on the stock-just-reset-again last version of the system.

I'm on stock - not even rooted

I'm on stock MM here as well.
Also, not sure if it a coincidence or not, but I changed this and haven't seen overnight battery drops anymore. In Settings>Location I changed the Mode from High accuracy to Battery saving. Since the Pixel C doesn't have GPS device, then why use it.
Like I said, not sure if it a coincidence, but battery life has been great overnight since.

So last night, I rebooted before I went to sleep, but overnight the battery drained from 85% down to 57% in about 8 hours.
I decided to check my location settings as per your post and found it was set to high accuracy, so I changed it to "Battery Saving".
I did nothing else(no reboot) until I checked my battery now about 3 hours later, it has only dropped by a further 2%.
Looking at "Battery Monitor Widget Pro" history statistics, it is clear to see that overnight the battery was draining considerably more.
It takes readings every 10 minutes and was showing between 450 and 275 mA being used every 10 minutes overnight.
Since I changed the location settings, most of the time it is 15mA with occasional jumps up to a max of 297mA.
Although this could not be classed as conclusive proof, it does seem to have had an effect, I will keep monitoring it to see how it goes.

Yep, I change that setting on the 19th or 20th and haven't seen any major drains overnight.
I think I may have found a winner with that little tweak

So far so good for me too. I don't know if it is related to the GPS settings, but no more inconsistent major drains so far.

if location services is on it can drain a good deal

Just to add that I had exactly the same issue on stock 7.1.2, tablet was staying awake and draining. Reduced location precision and now only a 2% drain during an 8 hour sleep which is a massive improvement.
