[LOG] Battery drainage on O2X

Since everybody has some problems with battery drainage i thought it would be usefull if everybody posts his or her battery stats after some time so we can compare them so we can find and solve "problems".
Add in your reply:
-Which rom are you using ?
-How is your battery doing over the night ?
-Is the battery inaccurate like it doesn't go higher then 98%, drops from 100 to 50 after some time or after reboot,... ?
-Which kernel ?
-2G/3G on or off ?
-CPU adjustments ?
-Programs freezed ?
- etc.
My stats:
-MDC Fear 5.3
-Drops 5% over 8 hours but when using it goes 20% over 1 hour
Which i didn't had with stock rom so i guess Fear 5.3 is the problem
-Doesn't go higher then 98% and after a reboot earlier it jumped from 100 to 42
-Kernel: 2.6.32.27-g9f26g51-dirty (Eternity kernel)
-2G and 3G diabled
-CPU adjustments 1ghz standard. When in sleep : 216mhz
-Programs freezed: Don't know because bloat freezer says it needs to be updated but i already have the latest version
-Go weather widget, netqin antivirus
Tracking battery status with Battery monitor widget

-TK-Rom v0.6
- I loose 5 to 10% per hour without doing anything !
- Sometime even if i have the "battery fully charged" popup, when I unplug, the battery indicator shows 98% ...
-2.6.32.27-g9f26g51-dirty
-2G/3G on
-1000MHz max and 300MHz min (foced when screen off)
- No freezed program
- Only one widget : Genie Widget
2 Push mail (hotmail exchange + gmail) + 1imap (checked each hour)
If I install Juice defender (free), my battery last 2 days.
Without Juice Defender, the phone turn off after 10h on (with only some SMS sent and 10min on XDA) ...

- Which rom are you using ?
Factory ROM, updated to V10b.

Allright so we can already see that the stock rom's don't have much of draining or am i wrong ?
because my stock also had less then 5% loss at the night
but your 3G is ALWAYS ON !!!!! :s
you mean that you can always use 3G without doing anything else to your settings after disabling wifi ? because the 3G icon is always noticeable on the status bar even when it's disabled

Yes. When at home both 3G and wifi are enabled.
GSM coverage is not great in some parts of the house where my router wifi is strong; while some rooms far from the wifi router gets decent GSM coverage. So, I just let the phone choose whichever way it wants to connect when at home.
When I leave home, I manually disable wifi with a widget to save wifi scanning for router whenever the phone comes out of sleep. 3G works everywhere else, so I just leave it on 24/7. 3G power usage is negligible when there is no data traffic even when it is enabled, it's basically GSM on standby power.

Okay but i haven't got 3g coverage in my area yet so
but i have got edge is it using more then 3G? i know the speed is a max of 200kbps but is it using more or less then 3G?

I think EDGE is like a fast GPRS connection, right? I had used GPRS (aka 2G) quite some time ago, and IIRC, GPRS is billed by data connection duration rather than by data traffic. If it's also the case for EDGE, you MUST NOT leave is enabled 24/7, or else you will get a gigantic phone bill at the end of the month!
But regarding EDGE's power usage, I am afraid I am not entirely sure if it behaves like a 3G connection. Best is you test it out while monitoring battery drain, or google around for the info.

-Which rom are you using ?
Standard V10B
-How is your battery doing over the night ?
Around 5% loss, during around 8 hours of stand-by. But I usually charge it over night.
-Is the battery inaccurate like it doesn't go higher then 98%, drops from 100 to 50 after some time or after reboot,... ?
Not that I've seen.

2.6.32.9

Always on.

Yes.

My background is mainly black (with some grids) and it's full off apps, and a battery widget.
And I've also turned down the LED button brightness down to 0.3 mA using HiddenMenu.
Currently my battery has lasted 22 hours and 16 minutes, with 44% remaining. Have used it all day as my MP3 player and I've been on the Android Market to update and download some stuff.
Pretty good so far

I've had a good look through the hiddenmenu settings but can't see the section to change the LED brightness and I'm stubborn so don't want to do it with an app?

I'm gonna try the old style Nexus One's method of battery calibration. Hopefully it works, though I am not confident.
1. Plug-in charger standby, do not turn on charger yet.
2. Drain battery till it auto shutdown.
3. When it auto shutdown, immediately turn on charger.
4. Let the phone charge for 4-5 hrs.
5. After 4-5 hrs, power up phone.
The above was the Battery Calibration for Nexus One before N1 has its own Battery Drivers build-into kernel and a proper Battery Calibration Application (found in Market).
As I said, I'm not confident but will try this method. Will report here if success or failure

Probably a good idea to have a small fan blowing to avoid the phone shutting down from the heat from a long recharge. Might also have to go through a few cycles to reach the battery's full potential, probably don't need the empty-to-full cycle. Please let us know what you find out.

I've accumulated tiny experience over at Nexus One Battery Calibration and I know a small thing or two about how "some" batteries work.
The thing about Nexus One battery is it has in-build EEPROM so its the almost perfect battery to perform calibration. As for O2X, its still infant stage so no one look into it yet. But the theory "should" be similiar.
I'm doubtful but hopeful
Edit 1 - heavy usage with screen on for 4.5 hrs. 12 hrs use. Manage to drain battery till 0% and it auto shutdown as I expected. Now performing off charging for at least 4 hrs. I was surprised to see before it auto shutdown where at 0% the voltage was 3362mV. Pretty impressive I would say. Now I'm optimistic ...... will report soon.
Edit - failed while auto shutdown I plugin assuming it was charging. 4.5 hrs later I power up and it is at 1%. Fail!
I plugin and start charging. Monitored the charging process and found for the first time the phone was cool while charging even cool till 100%.
I'm now using this new charge and seems good. Its cool, no longer hot.

Now i have got CM7
And must say that battery is holding out much better at sleep
4 hours and not even 1% down
So i would advise to switch to CM if you are trying some new roms !!

Have you guys tried the app BatteryCalibration from market?
I had the same prob as many of you, and this solved it for me.

Mackay Rom battery

Welcome guys
Does anyone know what's the best kernel for increasing battery life time
thnx all

you can increase battery life in every kernel. Under clock your cpu or change the governor. There are few apps for this, best for me is set cpu

I'm using mackay kernel and my governor is ondemandX
But under clocking will make the phone too slow (which I cannot get used to)
but in some roms like v30B ICS and I remember cm7 and Zeus
the whole night(wifi off / mobile data off / GPS off / Bluetooth off) just connected to network and it may consumes only 2%-3%
So is there any thing to do with Macaky rom/kernel
thnx

from 85% to 18% in just 6 Hours wifi on but not connected and screen off and everything else was off
I think this is huge now I will try BBS

Set wifi to off, when screen is off, also I really recommend Greenify, this saves a lot of juice, if you freeze the right apps
Sent from my LG-P760 using xda app-developers app

I also strongly recommend Greenify.
I have purchased the paid version and have most of the apps (including system ones) greenified. Battery life significantly improved and no problem with receiving messages etc.
I use "Better wifi on/off" as well, to automatically turn wifi off when my home network is not connected.
I would also advise switching automatic sync off. That's the culprit of battery drain for my OB.
Hope these helps.

Hi, all CM 10/CM10.1 roms seems to be more battery draining.

[Q] insane battery drain

Hi, i'm on insertcoin rom (4.3) and "android system" is using 95% of my battery !
I don't really want to factory reset, because i'm gsm unlocked .
I've seen many threads with the same issues on international htc one but no answers/solutions. Do you have the same issue ?
Actually my battery is as bad as my nexus 4, i can deal with it but i read people on internet talking about 18h+ battery life with like 4/5h screen on for the htc one (with healthy battery), which is pretty good, but mine lost battery even idle
I've tried to disable google syncing, htc backup, location services, google + photo upload..... it changed nothing
(finally a guy on xda told that "StartingDockService" is causing the drain for him, maybe it's the same for me, then how to stop/disable this service ?)
thanks for your help
screenshot : http://i.imgur.com/hB65IyI.png (gaming = 1%, android system 92% )

It's completely normal. If you see how min android system actually waked the device, it's probably only a few min. For some reason they messed the battery usage. As it it it doesn't tell anything actually, no more screen on time, apps are gathered together... I suggest you try gsam battery momitor, it's very useful
Sent from my HTCONE using Tapatalk

Okay, thank you
i installed betterbatterystats and yes, it show the real usage like screen on, internet, and it matches what i do, so no issues ! i'm calibrating my battery just to see if this improve my battery life.

I too had to leave insert coin . It's smooth but the battery drain is awful. I'm now on viper and it's much better. The community is not as helpful but the battery is great compared to insert coin
Sent from my unknown using XDA Premium 4 mobile app

thanks for your reply ! i'm gsm unlocked, and insertcoin has international icon support (3g, h icon for mobile data) and i don't know if viperone support these too,. (and btw i have a working config so i don't really want to flash another rom)
After a few days, it seems like I get 4h-5h screen-on with 3g (outside) and wifi (at home), so it's quite good , at least it lasts a full day .

If you havin' battery troubles I feel bad for you son...

I got 99 problems but my battery life ain't 1.
How to get the best battery life out of your Nexus 5
1. Location Services : If you are not in a neighborhood with a lot of wifi spots you will most likely feel this draining your battery life. Under settings make sure that Location Services is set to battery saving and not High accuracy.
2. Widgets : Weather widgets, games eat battery by constantly fetching information . Check the settings for these widgets and make sure they are using wifi and not updating the weather information every 30 mins or so. I keep my settings to update weather information every hour to keep it reasonable. The Gmail widget sometimes eats your battery too. I removed the widget and used an icon in the dock at the bottom to check my email.
3. Restart your phone : Sometimes residual processes from closed apps could cause issues. Restart your phone if you haven't done it in a while and it should clear up any unnecessary things.
4. Keep wifi on during sleep : I made sure my phone uses wifi even when its sleeping. 3g / 4g eats the battery like crazy if you turn off wifi when your phone sleeps. This should be a default setting as pointed out by some users. In my case it had been changed probably when I was tinkering with the phone. You can find this setting in the Settings -> Wifi -> advanced -> Keep wifi on during sleep.
You can also use apps like Greenify , Tasker , and Llama.
5. Don't use Automatic Brightness : Turns out if the sensors are constantly looking to adjust brightness it takes up more battery. I set my brightness at around 60% and it works just fine throughout the day.
6. Use wifi over 3G/4G/LTE if possible
7. Switch off wifi when using Data: Android doesnt switch off your WiFi when you use data because Google wants you to use it for Locations and help build their database of networks.Switch off WiFi completely when using data to save a good chunk of battery.
8. Turn off Vibration on touch : Typing uses quite a bit of battery over the course of a day. Try switching Vibration on touch off.
9. Use Franco Kernel: : This will require rooting your device however it makes it a lot more power efficient.
10. Turn down the Facebook refresh rate : Make sure it updates not very often( every 3-4 hours) or never. IMO your phone is better off without Facebook or any other battery hog social networking apps.
11. Greenify: Works with and without root. Use Greenify to hibernate apps when they should not be running in the background. This is best used for games that fetch information about deals or daily events (i.e. Battle Nations or Real Racing 3)
Feel free to add anything to my list.

4, 6, and 7.. it would all depend on your signal quality. i get MUCH better battery life on lte than on wifi. and i mean much! i get 5-6 hour screen on time without doing anything special. on wifi i get an hour to hour and a half less. so the wifi thing is just in your situation, and not for everyone.
9.. there are better kernels than franco kernel. and on top of that, kernels have so little influence on battery life. battery life is mostly about your personal use, your personal setup, your choice of apps used, and very much on the quality of your phone/data connection. everything else has very little influence, including kernels.

3. This I agree. I've had super strange battery drain if I don't restart the phone once in a few days. I refuse to believe its a bad app as there are no wakelocks, seems to be more of a phone idle battery drain or radio drain.
4. To be honest, it depends on the WiFi network. Some WiFi networks (typically at universities) have a strange and outright horrible battery drain the moment you connect to their network and leave the screen off.
6. Again to not repeat what I said earlier, I get better battery life if I connect to LTE instead of my school's WiFi. Download speeds over LTE are 2-5x greater than my school's WiFi, so race to idle may be happening here.
7. Most android phones today have minimal battery drain with WiFi left turned on. But it doesn't hurt turning WiFi off if there are many weak known WiFi networks around you.
8. Not sure how much you'll save, I don't even recall much of an increase of battery with this off. YMMV situation I suppose.
9. I've had better battery life with other kernels. Again it's a YMMV situation.
Not a bad guide really
Another tip is that if Google Play services keeps your phone awake for a long time, revert Google Search to an older version, reboot the phone. The wakelocks should be drastically reduced.

Using Nexus 5 with:
CyanogenMod Nightlies
ElementalX kernel
1d 2h 9ms on battery / 2h 17ms screen-on time / with 38% remaining!

Good information! ?
Only thing I'd say is to just remove the part about kernel completely. As said above, kernel makes little difference. I get 24 plus hours and 6 hours screen time on any ROM or kernel. It's all setup and usage.

Nothing new here. Good for noobs, but most will have done this already

I have found that turning location off completely has helped my battery life tremendously. While I was barely able to make it through the day before, now I can easily pass by with 40% or something and light usage. I've tried other things but nothing has improved my battery life as much as turning location off.

Yup! That's what toggles are for. Need it? 2 clicks and its on. That's always my advice.

[Q] what kind of battery life do you get from your installed ROM and Kernel?

Okay my old thread was closed because 'it was against the rules to comparing ROM's confused'
So here another thread without 'the comparing'
Which kernel and rom are you using and how is your battery life?:victory:

It's depends. If a rom includes a lot of functionality and runs in the background then will drain your battery for sure. Some rom has power saving mode and stop app using the internet when no needs etc

It obviously depends very much on how you use your phone
For me with light to average usage and Whatsapp, Threema and Calendar/email sync I usually get around 1%/hour with any of the AOSP ROMs I tried, always using Boeffla kernel with Zzzmove governor/battery extreme setting and a battery saver application switching off my mobile network when on WIFI.
With stock based ROMs it may be a slight tad lower, but for me it was too little to make a real difference....
Just my 2 cents
Axel
PS The 1% figure is calculated over 24-48 hours between charging, thus including the nights

Thanks for the reply, but what i mean with this thread is which rom + kernel you used and which work the best for you, but i can't just post that because people are gonna nag about it.

well, As I wrote for me it's pretty independent from the actual ROM. I tried liquid smooth, cm, omni, slim, amcha and resurrection remix.

It depends on usage style... But I am curious if there is any BATTERY BENCH MARKING!! Post if any one finds any that can be shared on this topic.. Cheers

Most important and often not taken into account is reception strength.
I measured that when Im on work and phone is iddle battery is eaten about 4% per hour.
At home its less than 2 %. In both cases I have no wifi connection, but wifi is scanning, gsm data is working, but locked at UMTS (3G, not HSxPA) and connected to 3 google accounts and 1 work email.
I saw strange behavior with waking up CPU when iddle.
When connected through usb to computer (linux station) I was watching changes when phone wasnt use at all
Code:
watch -n 5 --differences=permament adb shell cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state
And at home CPU was at lowest possible frequency, at work CPU is jumping, even to highest, but mostly stays bellow 600MHz
Differences are in localisation of antennas. At work I have weak signal, but also I am within range a few antennas, and software in galaxy sometimes is changing, when able to find better reception.
This means of course a lot of wakeup's and battery is eaten much faster.
Returning to the thread I see no point in comparison between different people cause even one device can survive twice longer depends on location.
The longest time in idle without any data connection enabled is 4 days on a yacht, so receptcion was weak, but device wasnt use at all (its about 1% battery per hour).
