Hey guys, I just downgraded from CM 6 to CM 5.0.7. Everything seems to be working perfectly, only my battery is draining quicker than usual. What's the best solution to solve this?
I had a similar issue with 5.0.8-DS. Ended up letting my phone charge overnight, wiping battery stats from recovery, and letting it drain until the phone turned off without plugging it back up. Worked for me.
Hi all;
so over the last few months i have flashed many custom roms, kernels etc...and always had battery issues...i have tried jugs battery fix, wiping battery stats..following many other battery optimization threads..but i never got the battery life i once had (when i first bought my phone)...
a few days ago my phone totally crashed..wouldnt charge etc..and i ended up having to do a complete restore..i did this by following these instructions
http://www.youtube.com/watch?v=hRFJJFW-XxI
....so from there, i unlocked again, reloaded CWM etc and i loaded 2.3.4 flashable zip (found in the forums) via CWM.
and voila..battery life AMAZING....after 8hours im usually still at 85%...by evening time after using the phone all day im still at about 60%
from here do what you want with roms..
i loaded the alien rom without adding the themes..and the battery life is as stated above..
so if you are having issues try hard resetting the phone then re unlocking the BL and upgrading via cwm to 2.3.4
my battery life i back to amazing.....
p.s. would be great if someone else who is having issues tried this and reported back as well...
p.s. this worked for me but i am not responsible if you mess up your phone!
Erm..
Ok Ill bite >,>
Where are these camera buttons your referring to in this guide of yours Atrix has three hard buttons and four soft buttons power, vol- and vol+ and menu home back and search.... you hard mod a camera button into this already packed phone Ill like to hear it XP
Interesting..
Couple of q's:
- which camera button?
- unlock bootloader again? Once unlocked it stays unlocked.
- I don't understand how doing a reset leads you to unlocking the bootloader again?

updated the hard reset instructions to reference a youtube video (not mine but describes how to do it)

it doesn't actually re-lock the bootloader. The BootLogo is replaced with the stock logo, which does NOT include the "UNLOCKED" in the upper left hand corner
sorry i didnt realize that..so skip this step for anyone that is going to try it...

well dont have the old recovery and even if i did cant read the things at all quality is very bad
me too really can't understand it properly, i need to get back that battery time, but How? can anyone else explain it Please?
Anyone except TC try this with sucess? I have Alien 4 with stock kernel and i am getting about 15 to 20 hours before death.
I could be wrong, but I'm fairly confident that the following information is correct:
Doing a factory reset on the stock android recovery simply wipes data, cache, and dalvik - all of which can be done with any of the after market recoveries.
I am unsure as to whether or not factory reset also wipes the battery stats in the stock android recovery.
Edit: It is highly recommended to wipe the battery stats after you install a new ROM or kernel. To do so the quick and easy way - charge the phone to 100%, reboot to recovery, clear battery, reboot. If is then recommended that you let the phone die (or at least get low) followed by a full charge 2-3 times to make the battery accurate. The most involved way to reset the battery stats is to charge to full with the phone off. When it says 100%, pull the battery, plug it back in, let it charge for an additional hour or two while still off like this. It will likely not show 100% after an hour or two, that's fine. Boot into recovery, wipe stats, start up the phone, then unplug it. Follow this will drains and full charges 2-3 times and you will be set. This helps to fix poor battery life when it is caused by a battery that will not fully charge.
OP you should try to drain the battery down to nothing. A lot of people who screw up their battery stats end up with bad battery, however at times you can get a very slow draining batter that will give you 20 hours with 60% left, and then when the phone hits 53% (random example), the battery will fall from there to dead in just a few minutes. This happened to me when I first flashed Ninja SF. I was amazed the battery until I decided to let the phone actually die.

Hello, i'm currently with quarx CM10 last build (2 nov). First time i installed it i noticed it help A LOT with battery consumption.. from 12 midnight till 10 am from the other day it went from 99 to 97... that is.. like a miracle. then i did something stupid.. i used "battery calibrator" and it ruined it. Today it wen from 12 to 10 am in the morning with 99 to 60 then 49 (typical battery jump)...
I repeat, it's in the night, were wifi is off, refresh is off and nothing (that's what i'm planning to discover) is running or updating.
I attach some screens.
1) first install of the new rom. you can see it sleeps like a baby.... plain.
2).. goes down.. and down... even though i'm not using it.
any comments, help or suggestions? thanks in advanced!

Make your phone recalibrate the battery. Follow the following steps:
1 Use the phone till you have 10% or less battery left.
2 Wipe battery stats from 2ndinit recovery.
3 Boot into CM10.
4 Charge your battery to 100%.
Doing this will make the phone generate a new battery stats file and should solve your problems.

i'll try that. but already done it when installed the last build for the second time. i do wipe cache / dalvik / batt stats then flash ROM and all over again with the wipes.

If you've uninstalled your battery calibrator app or if you've not used it after the wipe, then you shouldn't have any abnormal battery drain...
If wiping battery stats doesn't work, then most people recommend reflashing the ROM, but you've already done that, so you shouldn't have the battery drain now.
Just put your phone to sleep for a few hours, and let's see what happens after doing that.
This is what i did after seeing the sudden drop the other night:
- let it drain normal till the day finishes (at midnight, that's when i did the following)
- charged the battery to 100% and turn off phone.
- pull battery., connect charger to wall and recovery.
- install ROM without battery on. Wipe cache, dalvik, stats batt, install rom, wipe cache, dalvik and statts (again)
- boot into cm10, turn off screen and went to sleep.
- THIS morning, i saw it drained me up to 60 all night.
...
so as you can see.. i've already seen that after reflashing nothing has happened.
no, i didn't use again the calibrator.

I'm not 100% sure, but as far as I remember, the battery stats gets generated while CHARGING a drained battery.
That's why you should drain the battery, wipe stats and THEN charge it to 100%. As it charges, the battery sensor detects levels (15, 30, 60 and such I think) and generates the battery stats based on these readings.
Afterwards, based on these stats, it generates a reading of battery drain, as the battery sensor itself senses only certain levels.
So, drain, wipe and THEN charge. Do this and let me know if the problem still persists.

hmmm! never tried that!.. i was just charging it and it's in 90.. so i'll let it drain and tell you later thanks for that suggestion.
Still open to other comments though thanks to everyone who reads this.

Just read and engrave to your memory folks! Battery calibration never ever had a positive effect on the battery life and the battery usage shown in the android in-built "Battery Use"-app... and by the way, the stats are reset every time you unplug your nearly fully charged phone from the cable.
Hey, rather than blaming your battery stats I'd search for a process running all the time. Looks like something is keeping the phone awake.
The battery calibration IS A MYTH, as explained here, so don't waste your time wiping the values in Recovery. If you don't find any hyper-active processes with the following procedure, the drops might be related to a worn battery (I don't know how old your phone/battery is).
Open a terminal console and type:
$ top -n 1|head
(if you don't have Hacker's Keyboard installed and selected as Input Method you might need to copy and paste the line above, off course without the dollar sign).
Look at the processes listed as output and paste them here.

Hola slim , thanks for answering. here's the screen
You had it coming since you are using Swipe... It's chewing up your CPU, and consequently your battery. Search the site. Off the top of my head I think it was a common issue.

Swype? really?? shoot.. i love it.. even though i don't use it that much. Searched a bit but couldn't find much. Gonna try freezing it and see what happens. thanks.
Finally i managed with your help to accomplish some good sleep! here's the screen. i think it's awesome, never ever seen this.
thank you!!
we'll see if it gets better.
There's an interesting lesson to be learned here: if no deep sleep can be achieved, don't blame the ROM, and look for a stubborn process which refuses to stop when the kernel tell is to.
So, I have been using the Moto G4 Plus ( Indian Variant -XT1643 ) for a quite few months. Then 1-2 months ago, I rooted it, first with superuser and then replaced it with Magisk. I am using ElementalX kernel. But then after some days , the battery started acting weirdly. It drains very quickly. Also if I charge the phone fully and then reboot in bootloader , it drops to 15-16 . Sometimes the phone switches off at 10% battery. Even in idle, the battery drains very fast. When charged to 100%, the battery page of settings shows something like 45-55 mins left and that too varies. Currently on 56% it's showing 51 mins left. It's just 1 hour ago when I charged my phone to 100%. Is it time to replace the battery or is it a software issue as it drops to 15% in bootloader even if fully charged. Any help is appreciated. Thanks in advance.
I have the same problem but only with magisk, wih SuperSU everything is ok ?
Alright, I will try with SuperSu and update you. Thanks for the help.
Its software issue, may be ex kernel, magisk, supersu or any other app is draining it. Use better battery stats or similar like it and see who is sucking your battery juice.
And as you have already rooted your phone then try any custom rom as they dont have its problem (some may have also). And if wanna stick to stock rom then reset your phone and root it and then use for a while you will get the difference from before and now.

Ok. Its good to know that it's a software issue. I already tried factory reset but it didn't help. Strangely, the battery is fine now. I drained it completely and charged to 100%. Maybe that might have reset the battery stats or something. Anyways , if the problem still persists I will try custom ROM. Thanks a lot.

Hmmm, I never had battery drain issues while using ElementalX kernel rooted with Magisk (14.0).
At least not while using Motorola stock Nougat with the above.
Maybe your battery just lost its calibration as you assumed.
Hello guys, im having a battery issues, its draining too fast, and my phone just turn off when it reach 15%, i flashed custom rom, to see if that solve my problem, and i notice something really wierd, the system said is charged to 100% (battery percentage on system) but when i go to TWRP, it said it is only 75% charge, i recently change my battery so it is not a battery problem, so there is any way to re calibrate the battery to get full normal charge?
Sorry for my english.
