[Q] Terrible battery life on jellybean aosp roms - HTC One X

My battery life is considerably worse on jellybean aosp roms (I tried both the 4.1 and 4.2 version) than it was with stock ICS, and stock jellybean with sense, I'm sure that the battery lasted at least twice as much than it does now. I'm getting around 7-8 hours with a screen time of 2 - 2.5 hours at maxiumum, screen brightness at 50%, location turned off. It's clearly a software problem since the battery life with stock rom is so much better. Something must be wrong since everyone is reporting great battery life with the latest jellybean aosp rom.

I think you maybe hurrying to a conclusion.
After you flash the flash the ROM, wipe battery stats in cwm. Then let the ROM settle ( atleast 2 charge cycles ) .
Then see if you have the same battery problem

I'm on ice cold jelly 2.2 with the XML kernel #141repacked for the ROM. I get a steady 3 hours screen on time. Give that combo a try. Also the first few days the kernel and ROM have to settle so don't be too quick to judge it.

Thank you so much! I have deleted the battery stats file in cwm and it is immediately obvious that the battery life has improved.I can't believe how easy the fix was.

Sorry for the replies, but: the battery stats wipe is useless...
The file that you've removed is a file which contains the statics of battery.
It has nothing to do with the battery life, Google has confirmed this.
In fact, in TWRP and 4EXT recovery this wipe there isn't.
However, i think you have to calibrate your battery with some charge cycles

Guich, what i talked about was not fixing battery, just fixing the readings.
Example : especially on AOSP roms, if u put on charge, after some time green LED shows (meaning charge full) BUT battery bar is stuck at a lower level ( Example 76 ) .
And the bar doesnt move forward even after you keep it on charge even longer.
So i tried a battery stats wipe in cwm and then when i booted back, it properly showed 100%.
So what i recommended was to delete previous stats ( of different ROM which were carried into this one).
So now the phone starts monitoring battery anew (with no cache).
Sorry if you misunderstood me.

I think this fact is random.
In fact, all aosp rom that i tried didn't have this problem
And, teorically, this file was delete when you made a full wipe.
In fact in TWRP recovery there isn't the wipe for the battery

Battery stats file should be deleted each full charge, though I have noticed my phone crash (my fault messing about with UV) and then my batter jump from 8% to 45% which is quite a jump lol

I'm familiar with CWM, but I cannot find it in advanced menu.
Is it because after I upgrading my HumberOS CM10.1 to AOSP 3.15?
I did a wipe clean. Everything. Fresh install.
It happened after I finished upgrading to AOSP ROM 3.15. My battery shows nothing even I charged it for a whole night.
Only 2% batt left while I'm typing this message. I have to connect my SGT7 to charger but nothing happened. It shows that it's charging but too bad, its not.
I've never encounter this problem before. It would be nice & I would be grateful if you sir can help me through this problem.
Thanks for replying.

[Q] How to change sync frequency in MIUI ROM 1.2.4?

I just flashed MIUI last night and noticed that my battery is being sucked dry pretty fast. I suspected that it is due to sync being switched on. Where can I make adjustments to the frequencies of the sync?
Either from the app or Settings>Personal>Accounts & Sync
Although I didn't have ANYTHING setup last night when trying it and lost 6% in about 10 mins - something's not right
Try resetting your battery indicator http://www.miui-au.com/howtos/reset-battery-indicator/. It is also recomended somewhere on the miui-au.com site to not charge your phone while flashing because it is somehow disruptive for the indicator.
I know all that, I wipe:
data/cache
dalvik-cache
battery stats
rotation settings
before flashing ANY ROM. Battery life is still crap

The weird thing is I wasn't charging the battery while flashing. I find it a bit surprising for MIUI 1.2.4 to be quite a beast in battery usage.

What would you consider a good battery life?? I flashed to 1.2.4 and it seems to last me all day without any problems?BUt I have noticed slight 5%-8% drop in the 1st hour or so but then it stablises throughtout the day. Ive not tweaked my phone with setCPU and I dont intend to either.
Something is rly wrong with your MIUI. Anyway, never use that Kernel which comes with miui. Use Vork or Coutts Kernel.
pls download current widget from market and test how much mA it drains in "screen off". im using miui-au 1.2.4 r2 with vork kernel and im losing 1% per our with wifi, sync and gps on. it uses 4-5 mA with screen off.
With previous MIUI builds, and with my own ROM I'm using now, I can go from 7:30am til midnight and still be on circa 50% battery. This is with my normal weekday usage. It goes down to about 30% by end of the day on weekends as I use the phone more
This build drops 5% in a few minutes and I just don't see that as being any good

I don't need to download anything, the ROM was dropping battery with NOTHING setup except for Wi-Fi. I didn't even setup my Gmail account to get my contacts!!
I think I can skip the obvious as I know full well what I'm doing and never had this issue with previous MIUI builds, and I never use the stock kernel - I always go for a Coutts one before first boot

[Q] high battery drain on all roms!

Hi! Before i have got a drain of 3-6 mA with most of the roms, but suddenly all roms dain 16-20 mA. No matter if it is MIUI , cm7 or sense roms. They all have the same drain .. is my battery bad ?
Got my phone waterdamaged 2 weeks ago , but this bad battery time started yesterday...
First you need to calibrate the battery.
Charge your phone until Current Widget shows 0mA. Then go into recovery and delete battery stats. Let the phone discharge until it shuts down by itself, then charge until it is back to 0mA. That will calibrate the battery.
Secondly, new ROM's do take a few days to "learn" how to use the battery most efficiently so you wont get the best battery life instantly.

I know that ROM´s need a few days , but i have waited a few days ,and noticed that it is allways the same drain... But i will try calibrate my battery next
And please make sure that during the period of charging it the second time that you do not take it off the charger. That will mess up the calibration and you will have to start all over again.
you might want to try a new radio too
same for me. I tried everything I could.
I tried these roms:
-coredroid
-ARHD
-honey
-virtuous
-MIUI(current)
I tried these methods:
-multiple new recommended radio + ril
-battery calibration app + clear battery stats(recovery) @ 100%.
-full wipe 1.5
-re-root(hack kit v12.3)
-different kernels
When I first rooted my phone battery was perfect on any roms until I flashed ARHD,thats when my battery drainage happened.

I'm getting the same here... Started with ARDH too, then LeeDroid, now Virtuous.
Clean installs each time, apps restored using Titanium. Also re-flashed the recommended Radios too and calibrated the battery once.
Current drain is 15% / hour on Standby ~70+mA.
I noticed no unusal Wake Locks either.
I'm loving Virtuous, but thinking to go back to stock if the new Viruous update doesn't solve this.
Just whilst typing this I lost 2% :-(

[Q] Jellaxy CM9 battery life

Greetings and salutations!
I was wondering if anyone could help me with a battery issue, more specifically a Jellaxy CM9 one.
Yesterday I flashed the most recent release, and I am honestly worried I may have messed up my battery.
I hope not of course, maybe the rom is at fault.
I charged my phone to 100% before I flashed it, I did a full wipe and battery stat wipe in CWM before the rom flash and after.
I then proceeded to start the phone, and after about five minutes of use, the battery was down from 100% to 72%!
Automatic sync is off, automatic brightness is off. Wifi is off. No background apps are running.
I tried using Battery Calibration to reset the calibration/battery file, but the result is the same.
I tried doing a factory reset from within the rom (not CWM), the result is the same.
Has anyone else experienced this or did I do something/wrong forget something?
Its normal because ICS and jb use more ram and CPU. So battery usage will be more.
But not as fast as you said.

Well, try to discharge your phone until it fully drained, and charge your phone until it reaches to 100%, should be powered of,unplug, then use it the normal way, until it fully discharge and do the same, for at least 3 charging cycles.
Or charge your phone to 100% then before unplugging, go to /data/system and removed batterystats.bin.
I hope it will help, the first step is I think the most accurate, than using such apps.
Thank you,

Best is to charge and discharge for a few times without whiping battery stats. It will calibrate itself. Whiping battery stats to incrase battery life was already proven several times to be a myth. The stats will be anyway overwritten completely after a few cycles. So whiping them even can make things worse till the new stats are filled.
However under some circumstates this might help, but you must take into account it can first drain more till the stats are filled and you get accurate readings. I only once whiped the stats while changing the battery from a LI-Ion to a LI-Polymer because the LI-Polymer is behaving a bit different.
More important is to care about the full gaugue, because this can show incorrect values and fill the battery stats with these. This is for example the case if pluging in the charger at 30% and rebooting and getting after the reboot for example 70% displayed. It´s simply impossible the battery gets charged by about 40% within 1 or 2 minutes while it´s booting. The same often happens when going into CWM recovery and rebooting afterwards. Therefore I always charge the phone to 100% before going into recovery and keep the phone pluged into the charger while for example doing a backup or flashing a kernel.
There are many reasons why the battery can´t last that long. For example apps or services keeping you phone awake, wifi or mobile data being enabled the whole time, or the battery itself going down the hills. For me wifi is draining a lot, even with a reduced voltage in the kernel. One of the services that can cause high battery drain is the media server and media scanner if it can´t handle the media type or index the media names due to some SQL prefixes included in the names.
But when speaking about the kernel it looks like Arco fixed the high battery drain issue in the final CM9. I flashed it last night and il looks like it´s draining just as much as if I were using RC2 or RC3 with Arcos stock 2.6 kernel.

It´s nearly the same. Not exactly the same, but nearly the same, so it will not become better if you switch to CM9 EOL but probably a little bit worse. All depends to your battery health and how you are using your device.
I find the 2.6 kernel still a little bit better when it comes to battery life than the one in the final CM9, but since the differences are really small I´m already using the final release with a modified kernel.
This kernel has a few more optimizations for battery life and I will launch it quite soon after some more tests are done.
Don´t know how you are using your device and what apps are installed on your phone, but if your WiFi and Mobile Data is always on, there are a lot of apps running in the background and you are very often using your phone, your results are still very good.
Else better replace your battery with a new one, as there is no kernel that will turn a bad battery into a shiny new one.

Just change it without rebooting afterwards. If you reboot after changing this value, it will be reset to the default value (100).
So to permamently change this value on each reboot you need to use a tool that will do this for you at each booting. Don´t remember which app is actually supporting BLX, but there is one that will do this for you.

No. Go to CWM recovery. Flash kernel. Stay in CWM Recovery, whipe cache, whipe dalvik cache and fix permissions. Reboot. Then you can use root explorer to change the BLX value once it has booted.

[Q] CyanogenMod 10.2 Alpha (Build 3) --- great stuff, but battery drains fast

Hi,
I follow the forums here for years but have not posted yet, hence not allowed to post on the dev forum in the appropriate thread, had to open a new one
A couple of days ago I installed "[ROM][JB][4.3.1][JLS36I] CyanogenMod 10.2 Alpha (Build 3)" on my wife's phone. Until then she was still using the stock GingerBread ROM. The phone got so slow to the point of not being usable at all.
After I flashed to CM 10.2 it feels like a new phone. Lightning fast, good looks, everything works - fantastic, very much appreciated and thank you very much @ Devs!!! :good::good::good:
One big problem though:
When running the stock ROM the battery usually lasted about 2 days. Now, with CM10.2 it is empty after half a day. Since I did a full wipe before she is using less Apps as compared to before and there is no single big consumer. Just the typical mail apps, facebook etc.
When I look at the wakelocks there is one app consuming most CPU which is CSipSimple. But that app was also running before the upgrade when the battery lasted 2 days.
The screen seems to consume more power though, is that possible? Anyone else with similar experiences?
Thank you very much!

Hi,
I follow the forums here for years but have not posted yet, hence not allowed to post on the dev forum in the appropriate thread, had to open a new one
A couple of days ago I installed "[ROM][JB][4.3.1][JLS36I] CyanogenMod 10.2 Alpha (Build 3)" on my wife's phone. Until then she was still using the stock GingerBread ROM. The phone got so slow to the point of not being usable at all.
After I flashed to CM 10.2 it feels like a new phone. Lightning fast, good looks, everything works - fantastic, very much appreciated and thank you very much @ Devs!!! :good::good::good:

ok thanks let me do some reading.
Also yesterday I deactivated the SIP app and that helped of course. Still strange that the app consumed to much less power on Gingerbread compared to CM10.2
Thanks,

You can try out battery calibration app before new kernel. Cause there is no "wipe battery stats" on cwm 6.0.4.4. I had same problem, and its a bit effected on cm 10.2. It's free. Maybe it will solve your problem.
Battery Calibration
That sounds very good, let me try that!
I have the same issue with increased battery drain. Yet I've not been able to identify the source. I disabled a lot of services (with Disable Service), also deactivated unnecessary system apps.
Cell standby is also shown as a huge drainer, although I usually have a good signal and no losses (checked with Better Battery Stats). There are no wake locks out of the ordinary.
Now I'll try battery calibration to see if that helps at least some amount.
Actually for me nothing really helped.
I eventually identified the 3 apps that drained the battery via Wakelock detector.
Those apps are Facebook, GMX Mail (based on K9 mailer) and CSipCimple.
Before the update to 4.3 my wifes phone was running the stock gingerbread and did not have an issue at all with those apps.
Yet on CM4.3 they are draining the battery.
Once I uninstalled the apps the batter life is back to normal. Which is sad, because she needs those apps. But no other solution so far from my side....

Again the myth with whiping battery stats / battery calibration. Make a full charge and unplug the charger. This will whipe your battery stats.
And for the ones who never get this. The stats are just some data about apps consumption collected while the battery gets discharged. The ROMs are whiping them by itself on each full charge and after shuting down the phone.
This data has no Infulence to how long a battery lasts. It´s just collected to show you visually the statistics.

Thanks ... yeah well did not really expect it, but when you're desperate
At least I thought it helps with the effect that the first 50% of the battery last 3 times as long as the last 50%, but not even that changed

I had the same problem with my S4 running CM 10.2 stable. The battery was empty after 8 hours. What I did was to change the theme, and today i got 12 hours and only 20% of the battery gone and wi-fi/3g all the time. Well, I still have only one hour of screen up time, but that is how it was before... I don't know, i'm just saying! Maybe it helps. The theme i added is LunarUi 2.
All the best!
