[Motorola Atrix 2] Pilgrimtozion:
I've had very varying results with my battery. When I first got my phone, I barely made it through the day. Wifi was on, data push was on, data over mobile network was enabled, GPS and bluetooth was off. Of course, I downloaded apps all the time, was doing all different kinds of things. I'd wake up at 6 am and hardly make it till 5 pm - a few days, I didn't.

Then I let the battery drain, recharged it, drained it, recharged it, and all of a sudden I went 36 hours on my battery. I was delighted and thought I had beat the system. Granted, the 36 hours were with light usage - a few emails here and there with email on push and social networks on 10-minute interval syncing. Somewhere in there, I introduced Juice Defender on my phone, presuming it would help. Very hard to define whether it actually did or not.

I did the drain and charge two more times and noticed the battery life was starting to shorten. Whereas before it would stay at 100% for two hours, now it would go down to 90%. No fear, I made it through the day with 50% at 5pm and charged it with 30% left when I went to bed.

Last night, I turned on data push again. What a disaster! Here I am at 3:20 pm and I have 30% left, fearing that I may not make it home without my phone dying. I turned data push off earlier, but I don't think it has made a lot of difference at this point.

I don't have a lot of apps checking for notifications - Twitter every hour, Gmail Push, Facebook never. I do have Google Talk, but I haven't changed those setting throughout this whole process. I know my reception at work is not the greatest, but again - I made it 36 hours through two entire days here at work.

Any ideas based on all this information?
[Motorola Atrix 2] JRW 28:
Sounds like youve gotten it figured out yourself. 36 hrs is unbelievable do you really need to be getting more?
[Motorola Atrix 2] Pilgrimtozion:
Sounds like it, right? I'm just not sure whether the data push should make THAT much of a difference...
[Motorola Atrix 2] Douchewithaphone:
For me it depends, when I'm in school I usually have sleep on at least part of the day. If I don't game a whole lot I get a good 20 hours or so. Not bad.
[Motorola Atrix 2] Pilgrimtozion:
It's amazing how much difference data push makes. I turned it off and after charging my phone before I went to bed last night, it made it through the whole night on 100% - I only activated it once very briefly. I made 7h30m on 100%. What a difference data push (for social media) makes!! Won't be turning that back on any time soon.
[Motorola Atrix 2] lilhaiti:
When I first bought my A2 I was so eager to get my hands on it, that I didn't let it charge all the way for two day (charging here and there). Once I finally got it fully charged I was seeing nowhere near the battery life of my A1 and others were saying that it should be comparable or better. So I did a calibration and now I easily make it through around 16 hours off the charger with moderate to heavy usage everyday. Below are the steps I used to calibrate.

1. Your phone needs to be rooted to do this.

2. Install Battery Calibration by NeMa from the market

3. Plug your phone into a wall charger (not the computer)

4. Let it charge until it says Charged (plus about 10 - 15 more minutes) then open the Battery Calibration app and check the Current charge. Make it says 100% and more than 4200mV

5. If everything is good, hit "Battery Calibration"

6. Now run the phone all the way down without charging till it cuts off, then start it up and run it again until it cut off again.

7. While the phone is off, charge it to 100% using a wall charger. (Do not turn the phone on)

8. Full, turn on the phone and enjoy

My suggestion is to do the first charge overnight, hit calibrate in the morning, run it all day until it dies (should be close to night time), then charge it while off over night again and then you are ready to go.
[Motorola Atrix 2] JDtech1701:
I've yet to make 7 hrs. on 100%, but I turned WiFi off and turn it on only when I need to use it (because with the "legendary" battery I figured I could keep it on and still be good)...wow. Now I'm happy. But of course there's nothing wrong with being happier...so...I assume there's a forum somewhere on xda on how to root?
[Motorola Atrix 2] JRW 28:
This will give you everything you need on how to root

[Motorola Atrix 2] Gadgetz:
Rooting won't increase your battery life at all. That's usually done once a custom rom/kernel is flashed to the phone cause the dev will usually include some tweaks to the rom/kernel that does so.
[Motorola Atrix 2] JDtech1701:
Right, I just need to know how to root it so I can get the apps/roms/kernels that will allow me to extend battery life. And get rid of CIQ.
[Motorola Atrix 2] frycook15:
to get rid of CIQ you can download a freezer app from the market so check this thread out for that. also you can root your phone but the bootloader is still locked so theres no custom roms at this time but were hoping to have that taken care of soon.

On side note Device Health is the CIQ

http://xdaforums.com/showthread.php?t=1330235
[Motorola Atrix 2] Gadgetz:
no roms or kernels are available yet for the Atrix 2, sounds like it's gonna be a while. But you can get rid of CIQ via MyBackup Pro/Titanium Backup, and various other app freezing apps.
[Motorola Atrix 2] Atrixed2:
After rooting I was able to freeze a bunch of apps that runs in the background that increased my battery life. Its been 12 hours and still have 70% on my phone and i've been playing games while talking on blue tooth and woke up and my gf is still on the phone lol. I haven't done any calibration yet. Probably wait till I can't hold a charge for a day ^_^
[Motorola Atrix 2] holeshot77:
20% after moderate use of twitter and xda browsing and some marble blast in a 15 hour period.

My infuse would be deadin 5-6 hours. It sucked.

Sent from my mAtrix2!!
[Motorola Atrix 2] trey.mcd:
so after reading all of the suggestions (freezing settings, I have my social media scan about every 15 mins, and did some build.prop settings to decrease my wifi scan interval) I still have about 30% cell standby and another 26% for phone idle and my battery is down to 50% after 6 hours. Any other culprits I should be looking for? Or is this typical?
[Motorola Atrix 2] koriflame:
How long do you spend in areas of no/very low signal? At my university there is no signal whatsoever so i keep it in airplane mode otherwise cell standby starts getting up to 35-40%
[Motorola Atrix 2] trey.mcd:
I live in a "4G" market, but my local rep said we aren't getting 3g speeds. Better to manually try and switch to 3G? I have 5 bars just about everywhere in town
[Motorola Atrix 2] lilhaiti:
Thats about typical for my phone too and my battery life is amazing. I'd also check to see if any apps are "just running" using either the stock Task Manager or the Moto Task Manager.
[Motorola Atrix 2] trey.mcd:
Are you talking battery useage under the motor stats? Are you seeing simliar times for about 12 hours of total use?
[Motorola Atrix 2] lilhaiti:
Sorry,

I was talking about the usage percentages. As far as battery life I can get well over 16 hours with moderate to heavy usage. If you root you could try calibrating the battery.
[Motorola Atrix 2] trey.mcd:
Yeah, tried a calibration. Do you change your push frequency? I'm pulling my hair out trying to figure out what else to "freeze" as I did the majority of these that was posted in a different thread.
[Motorola Atrix 2] koriflame:
I used the "Custom" battery saver and made it so things only sync between 9:59pm and 10pm. idk if that has anything to do with it. That's the closest i could get to turning sync off completely.
[Motorola Atrix 2] Nsr238:
50 Hours on a charge!!

Battery Saver on "Maximum battery saver"

Background data "off"

WiFi, Bluetooth, GPS, & Sync "off"

Screen Brightness "5%" (or less)

JuiceDefender Ultimate "custom settings"

mobile data "enabled"

WiFi "enabled" - Option "WiFi Preferred"

[Motorola Atrix 2] Atrixed2:
@Androidarena Welcome to the forum ^_^v to start off I think any smartphone that is stock will not last more than 8 hours in inactive mode (not using it). A basic phone will last longer because there is no bloatware included/running in the background constantly.

First I would Root A2 then install the following:

Rom toolbox pro

ADW launcher or Go launcher ex

Data Enabler

Look somewhere in the A2 forum about what apps can be safely frozen usually (social stuff). Freeze any apps that you don't use but be carefull with the system files. A little research would do good :P

I play most of the day hmm to be exact Destinia and Inotia 3 with texting in and out. I usually don't surf on my phone because I'm right next to my pc lol. I'm contected to Wifi all the time when im home and disables it everytime i leave the house.

I use Data enabler to disable data when I'm not on wifi unless I need it. (I'm on 15 a month plan which i think is pricey. only used 16mb so far for a month) I don't need to be connected to my facebook all the time and check in every minute ^_^v "check-in story - I'm on a stop light at 1st ave... I'm now stuck on a red light at 2nd ave.. haha".

realistically I have not reached 24 hours without charging. Using Skype(videochat) and facebook drains my battery by 9pm and unplugged it from the charger at 7am.

I think I still do good with 15 hours of game time(4~6 combined hours)/Skype video chat 1 hour/ texting and calling / facebook updates. You can consider me gaming that much a heavy use :P

But I'm a normal person I plug in my phone at night before I go to bed (with 40% battery life to spare) usually at 10~11pm and wake up at 5:30 and use my phone around 6:30 till night time. I don't do 24 hour routine ^_^ hehehe
[Motorola Atrix 2] androidarena:
Thanks for the quick reply atrixed2. I still feel that ur usage is heavier than mine. Did not want to root it so quickly as wanted to stay in 30 day warranty. I might return da phone to reverse upgrade as it is last day and do not want 2 to bestuck with what I dont like.probably should have got sg s2. Better battery and performance for sure. Any takes on that?

Thanks
[Motorola Atrix 2] Atrixed2:
You're welcome ^_^ you can read this up

http://www.techradar.com/reviews/phones/mobile-phones/samsung-galaxy-s2-930907/review?artc_pg=9

It is about the battery life of S2. If I were you I would go to an At&t store that has SGS2 demo and play with it. The only reason I went with Moto is because I had samsungs before and no luck with them ^_^v So far my Moto A2 is doing what it supposed to be doing and it is making me smile. Quality of a product will always depend on the usage criiteria of the user :P Also if you are within your 30 days that is the best time to root to find out if you have to return the phone or not. In any case you want to return just uninstall superuser and your phone is back to normal. In the end of the day go with something that you really like and not what we say you should like hehehe, because you willl lose some sleep if you keep it ^_^
[Motorola Atrix 2] androidarena:
I tried to look at galaxy S2 and I Liked the screen and feel of it, so I believe the people who do not like S2 might have had a bad experience with Samsung before. In fact My friend has galaxy S 1 and he uses on the minimum and is still able to get more than 30-36 hrs on one charge. A close friend has galaxy s2 and he uses it very heavily with auto gmail and sync on wifi and it last him for one and a half day..... Plus more storage and good app development support as well. Plus there is extended battery in near future for SG2.

@atrixed2: I did read that review and it says some good things about battery of SG2. About rooting,I thought there is a way for best buy guys to figure out if I ever rooted the phone or is that phone rooted right now.... cuz they ran some tests when I first returned first model to them. Is it that rooting voids the warranty? I also feel that root for atrix 2 is not stable yet and I am a newbie to android, so don't know about back up and stuff at all! Not I cannot figure out.... but I have already spent so much time investigating about android and atrix 2 in general that I am fed up with smartphones in general!

Well, I don't really know now what to do!

Other atrix 2 users your opinion and findings? will be instrumental for me as well, any input is highly appreciated.
[Motorola Atrix 2] lilhaiti:
I will say this about devices and battery...I have read through a bunch of forums and no matter what device it is (Android, iOS, Blackberry, etc) there will always some people that will not get the expected battery life. The Atrix 1 and 2 are two of the best Android phones in terms of battery life, and it baffles me how people can get such varying results in battery life. I had GREAT battery life with my Atrix 1 and even better battery life with my Atrix 2. This is not a knock on the users who are getting poor battery life (I actually wish I could help you), this is a knock on the QC department of the phone manufacturers. I've read time and time again about people with poor battery life returning their phones and the second one getting much better battery life or replacing the battery on their seemingly new phone and instantly getting better battery life. With my Atrix 2 I was getting poor battery life out of the box, but then I rooted and tried calibrating the battery, and it has wonderful ever since. That is sad that a device that was brand new needed a battery calibration so soon. This in not a Motorola exclusive problem, other manufacturers have similar user stories. I do believe that Motorola is the best at the battery life thing. This is just my two cents, on battery life, again, I am not knocking anyone for having poor battery life, I am just stating that manufacturers should tighten up QC to minimize problems like this out of the box. (Jumps off soapbox)
[Motorola Atrix 2] Pilgrimtozion:
Depending on my usage, I get 24 hrs of usage if I let the battery run dry entirely. With light usage, I can make it through two days. I've not thought about rooting, though - perhaps I am too faint-hearted. Does it really make that much of a difference? And is it really safe (provided I use common sense, obviously)?
[Motorola Atrix 2] unsivil_audio:
I got 39 hours on my first charge cycle (I made it a point to run it down to <5%), moderate use. This phone is by far the best battery life I've ever experienced on an android phone. Coming from my HTC Aria with about 14-16hours moderate to heavy use.
[Motorola Atrix 2] androidarena:
Thanks unsivil_audio, Pilgrimtozion and lilhaiti for your valuable inputs. Unfortunately I had to return my phone and do the upgrade reversal. :(

I liked the phone a lot, but there were some issues I could not tolerate, out of 8 gig internal memory only 4 is available and that too only for apps??? So basically its good for what?? So you need to have a decent sd card, plus I know a lot of people had problems with it.... I was on my last day to reverse upgrade and did not want to risk and be unhappy for 2 more years!

I had a hard time playing with the moto software figuring out why I am not able to see my SD card first and then files on my internal storage? Believe me I used it on the very conservative mode and still did not help for battery, 2 days! Still a dream!

I know I might be the only person to cry foul but honestly thats what I experienced. Guess these days companies should focus more on optimizing the performance instead of getting more horse power on board! Hopefully I will be back soon with a new android device. Thanks to all.
[Motorola Atrix 2] unsivil_audio:
Well after having stellar battery life for the first week of owning this phone, its on the fritz, and I am now on a witch hunt. This just started today. Phone isn't entering a deep sleep state anymore. I'm going on 3.5hrs unplugged and down to 30% battery from a full charge.

After reviewing the battery stats, I've concluded that the phone isn't entering the sleep mode anymore when the screen is off. Instead of ~40mah drain with the screen off, I'm hitting at lowest ~250mah drain and as high as ~750mah. Again this only started today, I don't remember changing any settings and I've uninstalled any apps I installed in the past day. Anybody have any ideas?
[Motorola Atrix 2] JRW 28:
Sounds like a rogue app....try installing watchdog from the market and see if it will help you narrow it down
[Motorola Atrix 2] unsivil_audio:
Nope, just figured it out. I had been through watchdog and automatic task killer trying to find this gremlin. Turns out it was just some sort of glitch. The cpu wouldn't scale down from 1000 regardless of usage. Confirmed with CPU Master, rebooted and now it working perfectly again as confirmed by the battery and cpu stats.
[Motorola Atrix 2] rdhoggattjr:
Weird! Good that you found the problem.

I think the battery life on this thing is great. I can watch anime's on it all day and still have %30 when I get home.
[Motorola Atrix 2] mathk:
if you turn it on with auto network selections , plus lots of background apps like chat!go , whatsapp, viber , line , icq etc and use the internet , call other periodically.... you can still keep it alive for 8~12hours otherwise it can stay more than half day.

The battery life is great.

BUT I HIGHLY SUGGEST YOU TO BUY ONE OR TWO EXTRA BATTERIRES, LESS THAN 10 DOLLARS EACH.
[Motorola Atrix 2] koriflame:
My phone has had some reduced usage lately... 32hrs off the charger with 50% left. Thats still after playing games/moderate texts/wifi on 24/7
[Motorola Atrix 2] androidarena:
Atrix 2 is superior to S2 for lot of reasons.....

Hi Guys,

I returned my A2 and I am back with another Android device, the SG S2. It looks good and performs okay. I wanted to share my experience with all so far, may be it will help some newbie like me: :-)

According to me, Atrix 2 still rocks and gets a thumbs up for these reasons: All points are compared against Samsung Galaxy S2:

1. Call quality is MUCH better than S2.

2. Ear piece sounded crystal clear and sharp than S2. For some reason S2 sounds like monophonic (It might be really!). Atrix 2 earpiece and loudspeaker beats the crap out of S2.

3. Fells very much COMFORTABLE compared to S2, I liked the feeling of A2 than any other phone. It is easy to type, small and useful for my hands and rubbery soft back makes it anti skid. My S2, feels like it will fall down anytime and have to be careful :(

4. FM radio, S2 sucks on that. Music quality on A2 sounded excellent on A2, my S2 sucks on that. The FM felt like it was HD

5. Battery:

This was one of the reasons for me to jump to S2, but Poor me, paranoid me, I get the same juice out of my S2. I know it can do well, but I do not know what it is with me, I just cannot get past 16 hours of moderate usage.

6. Heating: S2 gets heated more quickly and feels like I can Iron my clothes with it.. yeah! I will definitely try next time... ha ha :)

---

So why do I still have it and not A2?, Screen and development with the device.

I wish, a dream device would be like A2 with the vibrant screen like S2 and battery performance like good old days....

I wish luck to you guys on the DEV for this device. Thanks for all the help and info.

You rock! Happy Holidays!
[Motorola Atrix 2] enoch861:
Hey guys, just moved over from the G2x forums to this phone (unlocked on T-Mobile).

I have to say, this phone has really good battery life. I've gone 22 hours with the screen on for 5 hours (Wi-Fi on with sleep policy set to never, heavy texting (800+), heavy web browsing (2+ hours constantly in chunks of 30+ minutes) some gaming, and 3 hours of music). That's some bomb proof battery life right there.

I would suggest for those of you guys posting how long your battery lasts, please include your screen on time. That allows us to gage how much the device was actually used because different people have different definitions for light, medium, and heavy use.
[Motorola Atrix 2] Pilgrimtozion:
I'd never be able to get that kind of battery life no matter how hard I tried. Not with background data on - even though I am very conservative on which apps I have on the phone and which ones sync and how often they sync. Not sure how you would do that unless you're rooted, in which case I need to know how to do that.

[Motorola Atrix 2] Pilgrimtozion:
How does it make such a large difference? I hear people talking about 35-45 hours on one charge, which sounds outlandish to me. Does it really make that much difference on my battery life? (which is the only reason I would root)
[Motorola Atrix 2] jimbridgman:
No it is not root per se that makes the battery life better. It is all the things you do and install that require root, that allow you have better battery life.

Some things like bloat freezer, that stop certain apps from doing what they do, that are just bloat software, this helps on battery life and requires root. There are a few apps that will help you handle many things within Android itself that require root, that can again help with battery life, by allowing you to stop unused services, and data, and sometimes allow you to stop data connections say at night time if need be. One of those apps is called Android assistant, and there are others like it in the market.

Without a whole bunch of crap like above I get an "Average" of 30 hours of battery life, with fairly good usage. I have a TON of background apps and live data, web surfing a few hours a day, checking XDA through the app, taking calls all through out the day (my office phone forwards to my personal cell), etc. With all of the stuff mentioned above I easily get 40+ hours between charges, and when I use it a little lighter, I get 2 whole days 48 hours.
[Motorola Atrix 2] Pilgrimtozion:
Thank you for the helpful reply - I am new to the Android community but consider myself smart enough to catch on to this stuff easily enough. I am looking forward to exploring what it can do for me and my battery life!
[Motorola Atrix 2] enoch861:
I actually wasn't rooted. Every time I get a new phone, I use it like a "Normal" person would. I don't kill apps, I just use the phone and all it's features like a non technical person would.

I can tell you that I do have 5 email addresses on my phone. 4 of which are on Push and 1 at 15 minutes refresh.

And I have over 120 apps.
[Motorola Atrix 2] devsk:
My battery life is amazing. My normal activities include occasional calls, check of work email, gmail, work calendar, browsing, playing angry birds for 30mins, andoku for 30mins in the day etc. And I get about 3-4 days battery life. Its standby retention is amazing. If I do very light email and occasional calls only, I can last for 6 days to the point where its almost out (10%).

I did not do anything specific to get this long battery life. Just rooted and removed crap.

This phone will beat anything and everything on battery life out there.
[Motorola Atrix 2] Pilgrimtozion:
**mouth drops open**

HOW?!? There is no way!! I can make it from 6 am to 10 pm with 30-40% and moderate usage...but nothing like that!! How?!? Is my battery THAT crappy?!?
[Motorola Atrix 2] devsk:
I think its just a combination of me being a light user and having very little running other than what's needed.

Yesterday, I played angry birds on it for 8 hours straight (slept at 6am...:D) and I went from 90% to 10%. So, it all depends on the usage.
[Motorola Atrix 2] bimmerd00d:
Standard battery, just decided to let it ride. 5% remaining, I could've made it 2 days I think if I let it die. Normal usage, gmail push and exchange hourly sync

I agree standby battery retention is amazing this phone.
[Motorola Atrix 2] Pilgrimtozion:
After an experiment this weekend, I got 40+ hours out of my battery twice in a row, in one case with about 20% to spare still. I set the phone to Maximum Battery Savings...and apparently not having the mobile data connection on all the time makes a world of difference. On standby, the phone lasts for ages and ages that way!
