[Q] Battery Drain

Hi all,
i'm new with DHD, i flashed Revolution rom and i have high battery drain.
I charged my phone untill current was 0 mA, deleted the battery info and reboot.
So i turned on only data connection and leaved about 8 hours sleeping.. from 10pm to 10am all sync are off.. the result is: -25%!!!
I'm trying to find the batterykillerapp but i can't do it!
If i type the code *#*#4636#*#* i can see only battery info, no battery history, if i try using Spare Parts the app crash
how can i find the app that sucks my battery life?

Go back to the thread and look for the radio recommended for the rom. I'm pretty sure these radios are the main reason for battery drain
OR
What do you mean by battery drain? if it goes down fast when you're using your phone. That's not battery drain at all.
You can also go to OC daemon and set governor to ondemand so that the CPU doesn't stay on higher clocks.

i mean that battery goes down fast when i'm not using the phone! -25% in a night
sleep governor is on conservative and wake governor ondemand

Hi, is it possible to wipe batery stats without having root or custom roms installed? My battery drains very fast.

@niyesuh
When you enter Recovery , your screen will be black ,that means you don't have a custom recovery installed . You need to have Root & RomManager whit Clockwork Recovery installed in order to wipe battery stats .

Hey guys, something better with recommended radio!
I'm using the phone from 15 h 24m and i'm at 52%
I think there is still something to fix because in 8 of this 15 h the phone was in sleeping mode and the battery gone down around of 15%
From battery info in the setting menu i can see: Display (40%); System (15%); Standby (13%); Dialer (13%); Idle (12%); Voice Call (5%); Whatsapp (2%).
Any suggestion?

How much in percent do your phone drain per hour?
Mine drain about 1-2%/H

now 1-2% me too, so it's ok? but peeks in the log means that something run in sleep mode, so i would find this app and kill it to have better battery perform

These peaks that you speak of can be the radio unit trying to find good reception. Try turning the data, LTE 3G and edge, off and see if it drains slower! But I don't see anything wierd with your battery usage or battery

I've got another question.. do you know what is better for the battery life? Should i charge it from 0% to 100% every time or trying to stay from 30-70% or if possible 40-60%?

Remember the thanks button
Well lithium batteries fell best if the are fully recharged once or twice a month and then charging just whenever you feel like it really! like from 30 to 76 percent. They do not need so much looking after.

Merci! I have already follow-up this way. I'll try again.

I don't have CM7 I have MS2Ginger 2.1 but I have the same problem. My battery drops 2 times: from 54--> 49 and from 25-->19...I had the same problem when I was using MIUIs and cm7 ROMs.
I think that the battery is just dead in those areas :-(

What does it mean "the battery is just dead in those areas" because when I use this rom (umts_jordan_emara-user 2.3.6 4.5.1-134_DFP-139 1318560162 release-keysEPU93_U_00.60.00) no problem.

Hmmm...Well Im goin to try this ROM too then.
I thought my battery cells were dead (smthn similar was on my notebook and when I replaced battery, everything was just fine) but if u say that everything is fine then I will try out that one.
Tnx.
Have u tried that CM7 ROM with different battery maybe?

No. I have my defy+ since November so the battery is new. I have only try ms2 ginger2.1 with the same problem. Only with motorola oem rom no problem like this.
I have erased files in /data/battd/ and wipe stats battery (i don't now if is the same things). I will come back after this test.

Try recalibrating with the method in this link: http://forum.xda-developers.com/showpost.php?p=11803458
I've used this many times without issues and it always helps with my battery life. With the Defy you have to follow the method that requires reinserting the battery before the lockscreen pulls up.

So after doing steps 1-5 then 6 then do we have to do step 7?
I didn understand you when is the right time to put back battery? Like in 8b?
After this crazy method, u don't have battery drops?

Skip step 7 and continue following from 8b. Hold your phone in your hand while it's booting without the battery and you should feel the haptic feedback (minor vibration) before the phone finishes booting to the lock screen. As soon as you feel the haptic feedback put the battery back in. Leave on the charger until it reaches 100% and then another 20 minutes after that.

can i use "battery callibration" for step 2 :
"2. Delete /data/system/batterystats.bin" ?

Ok. i confirm this steps works for defy+. Before unplug i have 4198mv and after 4164mv. Now, wait and see.

I have Defy with red lens and installed 2.3.6_4.5.2-109 DHT25_themed MultiLanguage ROM yesterday and fully charge it to 100% and one hour over that...Battery was on 4164mV...When unplugged it 99% and 4164mV.
But then i had like this:
54% - 3769mV
50% - 3757mV
49% - 3773mV
48% - 3760mV
...
...
27% - 3686mV
20% - 3692mV
19% - 3670mV
18% - 3679mV
Funny thing is that when gaps happened lower % has more mV than upper % ...
I will try this "new weird" method of calibration tomorrow when I fully charge my phone again tonight. Really hope this will fix my battery.

my defy on Cm 7.1 stable and i get 4160mV on 100% charged and still plugged in to electricity.
but after i unplug the charger, it downs to 99% - 4125mV..
i think i'll try that 'hard' calibration method

No.
i have a noob question for all: is it possible that the last 20% charge (80 -100) with a 1650 defy battery and rom not based on stock rom, be 'virtual', because i have 20% lost (69%-49%)? (sorry for my english)
Now i decide to put a new Battd file from the stock rom and i try again this hard calibration: charg at 100%. after step 8 i see 5% and 4317mv.
(100% full for defy+ battery is approximately 4320mV)

[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.

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.

[Q] Battery charging too fast

Hi guys.
I have a strange problem. My Gio charges from 3% to 100% in 3 minutes. It says fully charged...
Of course it's not real charging, if i unplug it, and start to play a game or just see my mails with wifi, it consumes that 100% on 5-10 minutes...
I've tried to charge the phone all night and the result is 2-3h of working time. If i use power consuming apps, like games, than it's just half an hour... I think that the phone stops somehow the charging process if it reaches to 100%.
I've tried to calibrate the battery, with program from market, and wiping batterystats from CWM too... It didn't help...
The strange thing is, that last week it worked well. Now something happened and it's ruinig my life...
I had THIS ROM when it started.
I've changed to THIS ROM, and it didn't solve the problem. All caches were wiped during flashing...
Any ideas?
Thanks for any help!

Hm you said you tried to calibrate the battery so it`s weird. I have sometimes the same problem but after a calibration it is fixed. I can only recommend to charge it overnight , make sure you`re not overclocking it , make sure you don`t use wifi , mobile data , gps , see if there`s an improvement keep it only with calls and messaging for 1 day see how that goes. Check also the battery maybe it has a spillage altough i don`t think that`s the case. Sorry that`s all i can say

Thanks for the advices.
I've just set the CPU governor to smartassv2. It was on Ondemand. Now I can discharge the phone with playing within 15 minutes. It's better than it was on ondemand...
I will try to use it like a regular phone, let's see how it works...

With any custom ROM my battery life is of 3 hours...
With stock is kinda 5 hours with 2G connection activated.
I'm waiting for a new battery, but if you want to keep your phone alive up to then:
- flash a stock ROM
- install as few apps as you can (I've G+, Stream (FB client), FB messanger, Viber, WhatsApp, App Cache Cleaner, AppZorter and xda app, nothing else T_T)
- do NOT use kernel different from stock
- hope you good luck because first times battery will be strange, after some full usage and discharge now I've the battery life I told before

Battery Problem
Guys
I updated my GD to 4.4.4 CM11 and everything is working ok except for one detail.
I carry my cell phone and start using normal, if not shut down or restart, but if I turn off or restart
sometimes ends when rebooting the battery for example was 74% back to 39%.
This has happened to me a few times, i already reinstalled the ROM, calibrated the battery but the problem remains.
Do you have any experience or story about this behavior?
