Of late, I have been having heavy drain of battery on my Atrix 2. I am running JB 4.1.2 (672.300.404.ME865.Retail.en.05). Trying to troubleshoot it (including recalibration) since the last few days without luck.
The symptoms...
- Sudden shut down - Have had 50%+ charge levels. Goes down to 5% and shuts down within minutes. (You can see the random drops in the charge levels in the pic)
- Completely drained out battery charges from above 40% when plugged in & charges to 100% in no time. (that 67% charge in the attachment is within 5 mimutes of power plug in)
Does the battery need a replacement?

Try changing battery... even i had same problem with Custom rom. Battery used to last only for 10 to 12 hours but now its more than 17 hours on JB 4.1.2 leak,,,,...Use stock rom. and remove any unncessesary apps and installl ROM again if u want :good:
How old is your Atrix 2? If over a year then battery surely begins to give lesser performance. Disable any other task killer / memory manager & just let OS do its thing. See if installing Media Scan disable from play helps & do not keep using random chargers, make use of original charger as received with phone. Finally see Better Battery Stats. It is said battery stats should never be wiped but see if it helps you and finally search for Apex's better battery life guide for many handy tips.
I disabled notifications, sync, froze higher wakelock apps & my battery life improved a bit but then it is no fun existing in a bare bones environment.

The phone is just about a year and half old. The drop in battery performance is just too drastic, sometimes it doesn't even last an hour after the charge. Will try to go back to original ROM and see if it improves else will probably have to go for a new battery pack.

Look like a battery problem to me its not the ROM but anyways turn off location services and wifi they are a big battery drainer
Use 2G when u dont need high speed.......
Try this app called Greenify https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
(it helps to reduce wakelocks and improves your battery life)
:laugh: Let me know if it helped (btw chck your battery and see if its defected they are amny ways to chck it read up the forums )
i have the same problem whit any rom of 4.2. when the custom rom shows 5% i change to stock ics rom an that show me 45%

Think mine is clearly a battery issue. Replaced the battery with a new one yesterday and now the phone lasts 6 hrs at least on a single charge.
CM 10.1.3
I couldn't write to developer's forum so I'm asking here.
I've recently firmwared my AT&T A2 CM 10.1.3 and battery drains really fast! The previous build was CM 10.1 (25th of June). I wiped cache and dalvik cache and firmwared CM 10.1.3. At least 3 people report that thie batteries on this ROM drain slow.
What did I do wrong???

Battery life varies so much from user to user that it is impossible to answer your question without A LOT more information.
Go here:
http://forum.xda-developers.com/showthread.php?t=1179809
Download the app and follow the directions in the op. That and reading through that thread itself should tell you everything you need to know about what is using up your battery.
That being said, everyone has different habits and expectations when it comes to their battery. What one person says is good battery life, another will likely say is bad. So just keep in mind that there is not a right or wrong, just what is right or wrong for you.
If I had a dollar for every time I said that, I'd be making money in a very weird way.
Thank you fro your answer. When I used previous version of CM the battery lasted 3 days with minimal using and turning the flight mode at night on.
As long as I installed newer version with JBX kernel the battery lasts 20 hrs max.
Power Tutor says that the most hungry apps are Android System and Kernel
can anyone tell me how to save the battery life of our pico on cm10.2 roms?
Its a fact that battery life is somewhat user variable.. depends upon your usage and how you have managed your settings. I suggest you read the reviews of the ROMs in the thread of the ROM which you want to try out. Reducing screen brightness.. regularly toggling mobile data and wifi , underclocking your kernel are some ways of increasing battery life.. On an average I used to get about 4 - 4.5 hours of screen on time .
Hope that helps you.
Cheers,

Always calibrate the battery after flashing a new ROM with "BatteryCalibration" ( author - NEMA)
I bought my nexus 5 couple of weeks ago and from the beginning I experienced a really poor battery life.
From the screenshot, please other nexus 5 users let me what do you think about this battery performance, is that normal ? When this screenshot is taken about 17% battery was remaining. Please suggest me how can I improve this battery performance.
I am using-
Stock rom
Rooted
Low brightness as possible
Google now disabled
Location off
There's a proper sticky battery life troubleshooting thread for this, it will tell you how to troubleshoot your issues better, no need to open another thread . Please post more detailed screenshots over there
But looking at your 'usage', in your list you seem to have forgotten to add "played Hay Day for 2 hours"
So my simple suggestion to improve your battery performance: don't play Hay Day for 2 hours....

2 hours gaming + 2 hours SOT. Where is the problem?
Need to use Per App Modes to underclock CPU for your games to get more out of it.

SOT would be Screen On Time
I imagine what he means is that something like Tasker when said app liek a game is open it underclocks the cpu and then resets it back to normal when you leave the app.
This would stop the cpu being put to max all the time and thus using more power consuming more battery.

I'm still not sure what you'll gain out of posting there though, your battery statistics are very skewed, which is why you have a perception of 'poor' battery life...
It's like driving a car at 100mph with the windows open, the stereo loud with the air con on...and then wondering why the tank is empty and the fuel economy is so bad...
Or leaving all the house lights and appliances on all the time, and wondering why the electricity meter is increasing so quickly.
Playing a mobile game for two hours...........not much different...it makes the battery life look 'poor' by most standards...
In all three cases, it's how you use it which will define how much energy / battery is used. Basic laws of physics
the 'Normal usage' is impossible for any user to define as we're all different, but still I'm going to guess that most of us don't include 2 hours gaming in that statistic
What kind of battery are you currently running on? That may be contributing to the short battery life.

of course, its his battery!
no way it has anything to do with 2 hours of gaming(sarcasm)
seriously though..
Read the first 2 posts in the thread linked above by @eddiehk6
Lots of tips there.
But as others said....2 hours of gaming will make your battery drop like a rock.
There's things in that link that can help you squeak a little more out of your battery....but gaming is the worst thing you can do to your battery life. Nothing you can do about it....except not play. So, keep the screen dimmer....and keep your charger handy.

I am really excited for upgrading my x play to marshmallow 6.0 from lollipop but after using it a while i am facing very less battery backup on marshmallow as compared to lollipop I merely get 3 hours of Screen On time and the battery last for 15-16 hours on normal usage.Is anyone else facing this problem !!
if you are rooted , try amplify and greenify, it helps a lot. you could also try to edit doze settings to make the device sleep faster than google intended.
mine Sot was reduced after MM, so i started tweaking doze and installed Greenify+Amlipfy. Now i get approx 50min-1hr SOT per 10%. i am not a heavy user, i do lots of browsing and whatsapp on data and i get around 6 hours SOT from 100-40%..never have drained the whole battery ..i guess it'll go beyond 10hour.[as battery saver kicks in at 15%].

if you need good battery then you have to cut down core functions according to your use.
I need the phone for whatapp and browsing so I turned off pretty much everything else like app auto-update I don't need Google to search every 30min if a new version is available, turned off NFC when I am not using.
@Himalaya saxena are you on stock rom or which one ? Check battery usage in System / Battery menu and report it. If you want people trying to help you please be more accurate and provide some detailed information and evidence.

NFC only uses little power. I keep it on all the time and still manage to get 6-7 hours SOT for every full charge
bluetooth is using extremely small amount of battery, too
it has LE profiles, so no need to turn it off, if someone is wondering about that
It seems there are quite few people with battery issues around... My phone lasts around 16hrs too, with everything pretty much turned off and very moderate use. No games, no videos, no music, no Facebook, no IMs. Just some Chrome, phone calls etc. My 2 year old Nexus 5 would last just as much, which is kinda laughable, given battery, SoC and age difference...

by going into
settings > battery and then clicking the three dots on top right > battery optimisation
Check that are apps getting optimised.
Also one more thing, By going to
Security > apps with usage access (at bottom) > Turn off the usage access of the apps there (would be play store and play services)
Do click the three dots on top right and touch the show system and another app named "motocareint" would show up. Turn it's usage access off also.
After doing all this, charge your device to 100 percent and then use normally till it hits 10 percent. Then share your battery stats.

Here's another issue: Roughly one hour after unplugging, used it at home, within WiFi range. Only Chrome and Tapatalk, 45mins SOT. 9% battery missing, but only 3% showing up here.
Edit: With time, the gap between actual battery status, and per-app usage stats gets bigger and bigger. Here's @ 70%, with app usage only giving 19% altogether.

Have you noticed that your phone does not last as long after an os update or just out of the blue? I've faced this issue countless times while changing roms, os versions or even between minor OS updates. After spending a good amount of time researching about possible causes for overnight standby battery drains, partial wakelocks seem to be one of the biggest offenders. The android developer website is a good resource to understand what partial wakelocks are. And as it turns out, you can figure out the app holding the partial wakelock and draining your precious battery without root or any changes to the bootloader/rom. Here we go:
Go to settings > battery and performance (poco f1 on miui) -> power usage ->Tap on the clock on the top right corner -> check if the awake field below the graph is a constant blue line. Or if the device has been awake a lot more than the time screen was on. Other roms also have this graphical view of battery stats under some other option. If the indicators for awake time aon matchre in sync, then this guide won't be able to help you any further. Otherwise move to step 2.
Install better battery stats xda edition from here. Follow the steps mentioned in this post for unrooted devices.
Open the better battery stats app on your phone and make sure the device is not charging. Lock your phone and let it sit for a few minutes.
Open the better battery stats app on your phone and check the CPU state view in dropdown at the top of the app. If percentage of deep sleep is lower than other states and you have not been using your phone a lot since it was last unplugged then the battery drain is real.
Next select the partial wakelock from the dropdown. If an app has a 100% time for wakelock ( duration unplugged = duration of wakelock ), then the app is the culprit. Either uninstall the app, or make sure the app does not have permissions to run in the background to avoid the battery drain.
I used the above steps to find out that MyAirtel app was holding a partial wakelock on PowerManager.wakelock all the time (even when it was not in background). Deleting the app fixed my battery drain which went from 10% per 8 hours to ~3% per 8 hours.
Hope this helps people resolve their battery drain issues.
So what happen if there's no partial wakelocks that's eating battery, but the batterylife is still subpar?

Check how many cycles of battery charges have happened. Battery is bound to degrade over time. You can follow this article to see how is your battery health.

Another way to do this using a USB charging monitor. To measure is to know but know what you measure!
A lot of mistakes I have seen on the internet is people checking the capacity the following way. They use the mAh that went into the phone. That is completely wrong since a batteries capacity in mAh is defined at the working voltage of the battery (3.7 or 3.8V) and not using the around 5V that the charger outputs. At QC voltages it will be even lower then!
The more correct way to measure a battery is to work in mWh (milli Watt hour) or the actual power going into the battery. With 'The more correct way' you must take into account that the charging circuit also takes a bit of the juice.
So in our case 3.8V and 4000mAh would result in 15.200mWh. So from 0 to 100% should result in around that value.
At this right moment I am checking mine after a year of use using the UM25C tester.
To be honest I am not really happy about the battery life since it drains about 2 to 3% per hour even during the nighttime on a Xiaomi.eu rom which even reinstalled from scratch to check if it helped.
My redmi note 5 pro is now on , and I bloody kid you not, 34% 6d 2h 3m, yes that is 6 days after I installed a clean rom. And yes, not really much use but still wifi active and a active sim card.
