Rooted to CM7 battery life dropped dramaticaly

Before I rooted I got a full day out of my battery, not I barely get half a day, I have a rooted Evo 4G with CM7 rom. Any ideas?
Thanks!

I'm guessing you didn't re-calibrate you battery, did you?

Charge the phone to 100% > boot into recovery > wipe battery stats > boot up, use the phone, make sure it fully discharges [so it turns itself off] > charge up to 100% again, use as normal.

ok did all the steps ... half day battery is in the red ... any other ideas? Or should I go back stock?

What kind of stuff do you have installed? Anything that might keep the phone awake or use a lot of data? Have your usage patterns of the phone changed since you rooted it (i.e., are you doing things with it that you didn't used to, like tethering or such).

[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.

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.
I lose about 1,5 % in deep sleep and about 5 % with heavy (e.g. streaming, gaming).

Of course per hour.
I haven't tested flight mode yet (completely useless, imo).
I don't expect any wonders, I can use my device a whole day with everything I want to do without a fear of battery dead.

PM me, I work at this very operator (in IT Outsourcing, but company is company).
EDIT: There you go (instead of xRecovery use CWM).
If this doesn't help either, here are more options.
ooidort said:
STEPS:
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.

It is for motorola, will it gonna work on htc ? Also when I charge my battery for 4 hours or for 48 ( turned off the phone I mean) it still lightning red led not green. Always it charged till 71 %

Worked for me on my WF using CM 7!

Okay I will try this, nut what about app Battery Calibration, does it work ?

Don't use an app because it is software based, but the guide i've posted is hardware based!

Ok thanks for the information !

1. While in Android, charge up to 100% and leave the phone plugged in.
it dosen't charge up to 100% to use this method

In this case 100% are the maximum you can reach. You can check the exact battery status in system settings!

1. Sorry, haven't thought about that. Yes, it has to be rooted.
2. If your phone is rooted you can find it with root explorer.
3. Yes, for rooting your phone needs to be S-OFF
Maybe you can use that one - found it in another topic:
1. Power on your phone then connect to your Charger and Fully charge until the LED changes Green.
2. Disconnect your phone from the charger and then power off.
3. Reconnect your phone to your charger with the power off and wait for the green LED.
4. Disconnect the phone from the charger and power it on.
5. Once the phone has fully booted / ready to use ... power off again.
6. With the power off connect the phone to the charger and wait for the green LED.
7. Disconnect from the Charger then power on and use normally.
Needs no root, but I haven't tried that yet. Most of the users said that it worked, but keep in mind that battery calibration can always damage your battery.

My battery never charge up to 100% last time i saw green light from fulfully charged phone was last year. I can charge it for 48 hours turned of it still wont be green

Which status is shown in phone->status->battery status?

Mediaserver is killing my battery!

Every day, I charge my Galaxy Nexus to 100% and in about two hours it's down to 15% regardless of whether I use it or not.
Every time I check on the battery, it says "Mediaserver 61%". Sometimes it's lower, sometimes it's higher. I barely have any media on the phone.
What do I do?

Come on, guys. My battery is dying!

Are you rooted? Which rom are you running if so. Have you been listening to music all day?

Then theres not really much i can tell you if your not rooted. Sorry. But a factory reset is what I'm thinking of. Could work. Make sure to backup first. (Take files and put them on your computer) rooting will defiantly fix your problem

You're tired to restart your phone? So you haven't read started it? Because usually a reboot would fix the random Mediaserver battery drain.

Yes, I've tried that but it doesn't work.
As an example, I rebooted it before going to sleep. It had a 75% charge. When I wake up - 30% and mediaserver took up 65% of it.

Then it's either one of your apps is misbehaving and you'll have to find it and remove it, or you'll have to factory reset the phone. You can try installing BetterBatteryStats first and check under partial wakelocks to see what apps are always running that could trigger the mediaserver. It's at least something to try other than wiping the phone I suppose.

Battery Drain

My 10 now is starting to drain battery real quick without doing anything. No unusual apps draining much. I used battery tester in the secret testing menu thing and it said my battery is fine but I don't think it is. Any app or something to test battery or any way to test if it's rom related?

Installing GSam battery monitor from the Play store would be a good start. You can monitor wakelocks and app usage, which can help diagnose your issue. How long does your battery usually last after a full charge, and what kind of screen on time are you getting? Also, does the phone ever get warm while you're using it?

From the main screen, you should have 4 icons at either the top or bottom of the screen. The second icon from the left brings up the app usage screen, and there is a drop-down menu at the top so you can view different things, like kernel wakelocks, etc.

OK I see but what am I exactly looking for? Wake locks? Not sure what's good and what's bad in terms of %s and what not

Like I said, charge your battery up to full. After a few hours off the charger, post screenshots of the main screen, app usage screen and kernel wakelock screen.
Also, press the triangle icon on the main screen and make sure "Since Last Full Charge" is selected.

I don't see anything out of the ordinary, but that doesn't mean there isn't an issue. There are a couple of things you can try. First, you can try and recalibrate your battery by turning the phone off and holding the power and both volume buttons down for approximately 2 minutes. The phone will cycle on and off a few times, which is normal. You can see how the phone works afterwards, and if that doesn't remedy it, I would RUU and start from scratch.
