[Q] Insane display battery usage

I'm on Runny 3.3 which I have had flashed for about a week.
Wiped completely before flashing (Full wipe EXT4 zip), never had this problem before.
Anyway, in this week I assumed that the battery usage would level out. I tried calibrating it, but display always takes up 93% of the battery usage.
Even on Runny 3.1 I had brilliant battery life. This problem has only occured on this ROM. I lost 7% from full in 20 minutes when I was using my phone for relatively basic tasks.
Should I reflash? What kind of values are you getting for display battery usage?

I have a solution my friend
I suffered this problem like a few days a go.
what you need to do is take a look at this post i hope it'll help

Thanks, but the link doesnt work lol

a wee bump for any help....

I changed the kernel to the Unity kernel and the display is now using 60 - 70 odd percent. Can't really test it though since its been plugged in since I flashed it. Will see how it goes tomorrow and report back

Please let me know, my battery lasts 8 hours with moderate 3 hours of onscreen time (at best)

For those who suffer this problem check out memnocs perfect battery guide
Btw I'm sorry the link didn't work. As a said take a look at memnocs guide its in dhd development page

The kernel didnt help much, the display usage has gone down but the other things have gone up lol a lot more than I expected. Will try that battery guide now.

lol what do you expect? the display is the biggest battery-eating-monster in our phone. it's completely normal that it drains that much.
fyi: my phone drains ~250-300 mA with display on, lowest brightness level, ~500 with maximum brightness level and 1-8mA in standby.
so: ~500mA/h and we have a 1200mA/h (probably less than that, since Li-Ion batteries lose capacity after some months) battery -> about 2h display on at maximum brightness

its weird because this "problem" occours only with sense rom.
On Cm7 and miui the screen was under 50% of battery usage...

Most non sense roms don't calculate ic correctly.
You can use an app called battery monitor widget to watch your battey drain if you want to.

[Q] Battery Drain - Yet another whining thread - CM7.2

Hello all together
I'm browsing xda for a little more than a year now. You guys helped me a lot!
First I want to apology my english, I hope you understand what I want to say
Not a long time ago the battery of my WFS lasted up to 3 days (incredible if I think of it now).
That was with a self rooted stock rom and some changes (bravia, turboboost script, oc-kernel, etc.).
Out of nowhere I had problems with my calendar.sync.provider. Processes htc.bg and htc.bgp used the most of my battery (found out with Battery Mix).
I could watch the percent falling... Battery was getting very hot.
After i killed calendar.provider and calendar itself those bg-processes disappeared and all went back to normal.
Installed m1nd's rom, tried a lot of different settings, used calengoo instead of normal calendar (uninstalled the other)...
But battery life was never the same since then.
We also had a really rough winter and I was outside a lot. my battery began to drain faster. First I began to install apps like "auto wifi toggle" to stop that battery drain, after all I just bought a new battery this spring - 1500mAh.
But other than i expected - battery life did not increase. So I decided to install CM7.2 (wanted to do it anyway - great work btw!).
And guess what, nothing changed...
You will find some screenshots at the end... (did barely use the phone this 4 hours)
So what can I do? I'm desperate. The battery does not hold the whole day...
Please give me some tipps (if you have others than the general battery saving thread) or at least cheer me up
tl;dr: Phone works for 10h (mail,text, no phones, no games) - Changing battery & ROM does not fix battery drain...
Thank you in advance!

it happens to me too unfortunately, i charge it everyday or every 2 days
when i play a small mini game for a few minutes, battery drains like over 10% in a few minutes.

Have you tried calibrating the battery?

Hey scilax can you please tell me how to. Calibrate the battery.
Me too get a smaller backup when 3g is used for some 3 to 4 hours.
Please tell about that calibrating

Thing is, I charge my phone everyday. And I've been using CM7 or CM9, battery life never lasts more than a day. If it's only lasting 4-10 hours. Check your sync settings. Keep it only on 2G networks if using data. Get a battery saving application, in my opinion, it sounds like your using a lot of mobile data/wifi.

Please open this!!

Hi, now that i have your attention!
I have cm7.2 democracy on my gio
I barely use it for wifi or gaming now because the battery is S**t.
I had 2.3.6 GB before and battery could take out 2 days on games and music. Now suddenly after switching to cm7.2 i need to charge it twice a day without using any app or game. just some texting like 10, 12.
I use ondemand governor and max freq is 806 min is 245
Also a couple of times i have seen that when my battery is at 30% and charge it then within 5-10 minutes it showed 100% charged. Unplug the charger.
Any suggestions or something on this? I really need an answer guys. Thanks

I can tell you that you can't charge your battery within 10 minutes.
Charge it at least 2 hours, 2.5.

Yeah! I will. Even if it says fully charged. IDK whats the problem with it. It drains so quickly.
Even if i charge it 2 hours even then i have to charge it twice a day.

I have the same problems. Some help?

I am having the same happening with my phone. I am looking into buying a new battery.

My phone goes from 100% to 10% on five min plz help

No one has found a solution 'till now?I'll try to use ODIN and go back to stock version, maybe that will help. Has anyone had those battery problems before using a custom ROM?with stock my battery used to last 2 days with games and music etc, now I can only use it for 5 hours without any games or music or internet. It also charges from 0 to 100% in 30 minutes , maybe less. I'm still hoping someone found a solution for this problem because it is useless to have a phone without any battery.

Try to get a new battery because huge draining problem is not caused by roms it caused by battery damage.my battery runs on stock rom over the 10days without using anything but on cm9/10 roms it drains faster but still runs more than 3days for me.

so no one got it?
Thank God I am not the only one here
But guys, I have been using stock GB for an year. Its been only a week on cm7.2 democracy and nightly.
Both have same battery issues and non of this happened in stock
It's not the battery issue.its something else. I'm sure

Have you tried going back to stock version using ODIN?I think that is the ultimate solution before sending my phone to service(I still have warranty).

Try to "recalibrate" your battery; in cwm theres an option "wipe battery stats". some say its nonsense, some say it really helps; i would give it a try.
No idea if theres an option with stock roms, though.....

I'm calibrating now...Will post the result in a while. (Tomorrow i guess)

I still couldn't solve this..I flashed the stock firmware with ODIN and still no luck, I'm starting to think it is a hardware problem, maybe I will send the phone to service now that I have the stock firmware back. Has anyone found any solution?

Hey, i found this article
For the users who like to try out new ROMs very often or by default Android receives updates to Android very often. These updates re constantly pushed to the users to provide the better experience to the users. For those who flash their mobile handset with custom ROM they are advised to charge their handset to 100 % battery life and then proceed with the upgrade processor. That is advised because if you have 50 % of battery life and proceed with firmware update, the new custom ROM will consider 50 % battery life as the full battery stats and this will provide half the battery life then earlier as specified by your phone manufacturer. In those cases you need to go with the battery calibration to gain 100 % battery backup as specified by your provider. There is complete procedure on how you will calibrate your phone battery is mentioned by us and if you would like to make the process very much easier then you can make use of a specially designed application which calibrates your battery. (Battery Calibration)
Okay so i flashed a new custom rom with 100% battery but no luck on battery issue. Its still draining the same.
then i calibrated my battery with this app with my battery at 100% which of course is 50% as said by this article, the app said "Your battery has been calibrated by 6%". Don't know what that means.
ANY HELP? DEVELOPERS PLEASE GUYS!

Try to calibrate it too.It may fix it.

I said i calibrated it but still it charges quickly to 100% as it has no effect on the battery anyhow.

I have the same issue, I am using CM10.1 RC0 by Olddroid but I think my problem is the charger. For the last month I charged my Gio using the usb connection from PC. Now, if I use the charger the battery drains faster than charging with the usb connection method. I am gonna buy a 1500 mAh battery and hope to solve this problem.

Battery Problem

Usually i using cm10a4. The battery life is really good.
8hours deep sleep just eat 5-15% of batt.
But now... cm9 and cm10... All the same. MY battery won't hold for long time
8hours deep sleep eat a lot of my battery!
it make me have to recharge everyday...
I found some People got this prob too. They said it's Kernel problem...
Does it true?
I have tried Battery CAlb. but still the same.
The battery app say my batt can hold for 1day 16hours 34min.
but suddenly change to 5 hours 23min.
please help ...

cm10.1 most likely same as cm10 regarding battery life.
try using betterbatterystats maybe there is some culprit. and also check your network signal. bad signal also affect on power consumsion. unstable signal cause cpu to work more.

using better battery stats (bbs) is great for killing some of the wakelocks in your phones (since not all wakelocks are directly identifiable, at least remove those most problematic is good enough). However, take it from me that bbs itself is causing serious drains to your battery. After spending 2 days with bbs, successfully eliminating most of the problematic wakelock, i used titanium backup pro to freeze bbs and my battery life improved tremendously! (from 4% drop an hour which is a little high, to 1% per hour). I am using Queen Anne's Revenge v2.3 rom with hurtsky cm9 kernel v2.1 (the latest 2.2 seems buggy), underclocked to 1MHz (shouldn't matter when it comes to just idling) and undervolted to extreme-UV values provided by CastagnaIT kernel here (credits to pepoluan for providing the link to the UV table)

Hi,
Based on what you are saying I can only recommend a new battery, since Android Jelly Bean (4.1.2) is battery draining, but clearly not as much as yours.When my phone is on standby (idle), and I wake about 8 hours later, it still has only lost up to 10%. However, I have a Xperia S so it should be a bit different...
I hope I helped.
If you have any question on changing battery on Xperia ion, feel free to ask.

Hi,
-you could enable stamina mode, it should be in power managment.
-You could flash back Android ICS 4.04 or GB 2.3 and see if it helps...
-When phone reaches 50% in battery level turn it off and pick out the battery (IF YOU MANAGE TO DO THIS) for a few minutes. Put it back and connect the charger, now charge the phone turned off for about 5 hours or overnight. Start the phone as normal and check if the battery life time has improved. (source for last advice:http://talk.sonymobile.com/message/154243#154243)
If I helped, press thanks

yipeee i think my problem is sloved
i tried instaling ics again and no improvement in battery,then i change it back to JB and root it.then i installed CWM and cleaned my dalvik cache,now my battery is awesm, for 7 hours of sleep it only drains 6%,no battery saver used,just extend battery life under battery settings. i think cleaning cache resolved my problem
