Since I'm also thinking about the GS3, over in a thread about battery life in the AC forum, some folks there said apps like Juice Defender and other task killers aren't a good idea since they take up space and can affect performance. Since the AHD only has 1 gig RAM I wonder if this is a good idea? Clearly the battery and camera are the weak points of this phone.

Battery / camera

Battery has been better than expected but the camera is horrible as someone mentioned. I just ordered an EB40 from the razr maxx to throw in ill let you guys know how it goes. I took that back off and it looks fairly simple, wish me luck.
[Motorola Atrix HD] reddog:
Please let us know how your EB40 upgrade goes..I would like to do the same.
[Motorola Atrix HD] canecbr600:
Its my understanding that u need a new deeper battery cover to use the eb40 battery. Please keep us updated....
[Motorola Atrix HD] reddog:
I did a quick visual comparison they appear to be almost the same depth (backcover)..but we will wait for the results from him.
[Motorola Atrix HD] Billy Madison:
First try to turn that autobrightness off. It's cool but it constantly eats up battery

Second turn brightness level to 100% and leave it there

Third try to turn autorotation off. It's cool but it constantly eats up battery

And try to shut down those zombie processes like put to background gameloft games and similar apps. Try apps like betterbatterysaver to find and kill those unneeded zombie soft

If it will help tell us. If it'll do worse tell us anyway
[Motorola Atrix HD] boufa:
I have this in another thread, but my battery life has been good and bad. I am finding sudden discharge of the battery, on an increasingly regular basis. I actually caught it do it yesterday.

I went from fully charged.. and plugged in.... to dead and unable to turn on instantly. In the past few weeks I have seen it drop 30-50% at random, and suddenly. When you look at the battery use chart, it drops nice and evenly, then straight down! Some of these people who have stated they cannot get more than a few hours out of the phone, or even a work day, might have the same issue.

I am not sure if it is hardware or software, but I have a replacement from AT&T on its way, and then we will see.

edit... I have also caught it twice refuse to charge until after a reboot.
[Motorola Atrix HD] princedakkar:
Battery doing good

The battery life sucked at first but like you I installed juice defender and it made a huge difference not only that I also downloaded supertool box and that help a lot also.
[Motorola Atrix HD] dcard2000:
If I connect to LTE, the battery drains pretty quickly...down to about 50% after about 3 hours.

EB 40

Just got confirmation that the battery will be here Friday ill post again with pictures of how the "surgery" goes. I was thinking that worst case i could order a separate back and dremel out where the battery is then just put a carbon invisi-shield over it and it would look normal and be protected but i hope i wont even have to do that. wish me luck :)
[Motorola Atrix HD] RobAndroid:
Considering my Captivate could last a day and a half I don't think I'm being too critical to expect it to last until I go to bed.
[Motorola Atrix HD] ML417:
I found that mine lasts for the duration of the day fine, but that's only if I charge it while driving. I bought a good 2 USB 2Ah car charger off of amazon, and with a couple of short 5-10 minute drives in a day, i can make my phone last the entire day until i go to bed.
[Motorola Atrix HD] reddog:
Hopefully you do not have to do too much "surgery".
[Motorola Atrix HD] seth_dare:
No time for all of the details but the battery was installed without to much trouble. Had to adjust some connections under the top of the housing (speaker, antenna and headphone jack) but its on just fine*. The main issues so far is that it doesnt show the correct battery level. When i get more time ill look into that but so far so good. Also, i pray this battery is worth a damn...never had good luck with ebay batteries but who knows.

*the battery is thicker which made these unable to make a pressure connections so i basically bent the pins up a bit and they worked great. On the speaker i took a piece of rubber to lift it a but to make it because the connections could not be manipulated.

Ill try to get some pics monday at work when i have more time...but for now its off to the zoo with the fam!!! :victory:

Well I broke down and got an EB40 battery for my phone. Installation was easy..only mod needed was to remove 2mm of extra plastic that was blocking the EB40 from clearing the base housing. Back cover reinstalled fine..you can hardly tell unless I point it out. Phone feels better in my hands. The only issue I have it that my phone is not reading the new battery correctly. Before installing it I charged the battery up externally. Does anyone know the correct process to have the meter re-calibrated to read the new battery?
[Motorola Atrix HD] dumon:
My phone lost 40% overnight in airplane mode today. It was discharging normally during the day loosing approx 1% per hour in idle. Before i went to sleep i put it in airplane mode with 50% charge. After 7 hrs it went down to 10%.

Also one night i put it to "sleep" mode and it lost about 20% overnight.

I own it for several days only and so far battery is the biggest trouble.

I don't have any apps installed it is pretty much factory defaults.

Edit: running Current Widget now and it is constantly over 120 mA in idle mode.

Is there any easy way to find what process is consuming it? Android battery stat does not show anything unusual.
[Motorola Atrix HD] overlord727:
Do you mind posting pictures? I'm curious to see what this looks like... Also wondering about battery calibration as well.

[Motorola Atrix HD] davezaff:
Check your smart actions.....may be you have the late night as an important time?
[Motorola Atrix HD] rschwam:
Just got my Atrix HD on Tuesday, on Wednesday I got home after work with the phone sitting at at 2% battery and almost ready to shut itself down. That night I installed Juice Defender on it and have gotten home from work with somewhere between 50% and 30% of the battery left, so it definitely helps a lot. I'm sure once the new wears off of it a bit then it'll be fine.
[Motorola Atrix HD] reddog:
Ok..so I didn't do a good XDA job by taking pictures of the work done inside the phone and I don't want to risk popping one of my corner snaps on the flexible back cover by reopening. I honestly didn't think anyone would want to try this...but I have posted some pictures of the after mod side profile of the phone.

So I will try and explain what I did...note DO NOT BLAME ME if you cut yourself, damage your screen, phone, desk or anything else. Do this at your own risk..

If you decide to do this upgrade I can tell you it is very simple if you take your time.

The base back cover is holding the speaker and antenna. It has about 2 cm of plastic where they stick on the speaker baffle..white sticker that you see after removing the flexible back cover.

Once you remove the 8-9 screws to remove the base back cover from the front LCD,motherboard etc you simply cut down the left and right side of this area by about .5 cm then with a sharp box cutter or blade cut a line that joins your left and right cuts..scribe this line a couple of times so that when you pull it back it will snap the extra plastic in a clean straight line.

By removing this extra .5 cm of plastic you will allow EB40 to fit into the phone better and allow for the base back cover to reinstall cleaner. Also the EB40 is shorter than the EB20 so once you installed the screws for the power connector of the battery push it down so that you have more space across the top of the battery box in the phone.

Carefully snap back in your base back cover securing the top screws by the speaker, flash camera first..do not over tighten..you are putting screws into plastic and can strip out the holes..

Once you got the base back cover back in test your phone speaker, flash, camera, power button and volume up down..once you know everything is good. reinstall the flexible back cover again starting from the top of the phone. This will allow it snap back into place and secure the battery inside the phone...

You are now done...again you can see from my pictures you can not tell it has a 3200 mAh battery installed..but can feel the additional weight.

The phone is now running and hold a charge like it should have been from day one..again I only need to figure out how to get the battery meter calibrated correctly to map the voltage to percentage...if someone to help me with this I would be grateful.
[Motorola Atrix HD] dreamliner330:
^So basically, your shaving the back cover down to allow fitment of the larger battery? I will totally do this as soon as I can buy BOTH a RAZR MAXX battery & a second back cover. I'll modify my 2nd cover and leave one in tact, so I can go back if needed.

I will totally document this step by step when the items are available.

:good:

I also want to know about the calibration. I don't just want a bigger battery, I want the phone to understand it too.
[Motorola Atrix HD] reddog:
Well I wouldn't say I shaved down the back cover..I would say I opened it up more square area the in the base housing. The actual back cover was untouched..

You are right on the on not just wanting a bigger battery..I will try different things to see if I could figure out the calibration..but I can tell you the performance of the phone "usability" is excellent now...I mean I have been playing with the thing two and half days..watching movies, surfing phone calls etc...all in an attempt to run the battery down to recharge it within the phone to see what happens with calibration..I am now on 2days 7hr and 44min with 5 percent still left doing my best to get it to zero..before I could get it to zero in less than a day.. Take a look at the screenshots.

So a quick question I would have to everyone..with a battery voltage of 3.594V should I be at 5% or more?
[Motorola Atrix HD] Brand New:
Oh lawd, dat battery life. You could make it 3 days I bet. :good:
[Motorola Atrix HD] jgvillan74:
How did you get the back cover off? I know, stupid question. :p
[Motorola Atrix HD] reddog:
I started by removing the SD and SIM card..then right inside the access door you will find that corner of back cover flexes out very easy..using a plastic removal tool of some sort.."no sharp items you do not want to damage your back cover by scratching it if it slips..or worse your hand"..

Use this tool to get up under the back cover to easy it out and up..once you get one corner started you can then slide that same tool all the way around the cover..the trick to easy removal is to pull the lip forward first to make sure the built in lip(s) of the back cover is clear of the phone then push up..

Once you have cleared the lips on the cover around the phone you will then need to start working on pulling the cover away from the battery...NOTE: They used double sided tape to hold the back cover down onto the EB20 battery because there is about a 1.5mm gap between the actual cover and the battery when you remove this tape.

Caution: Do not get over joyed and rip away your USB port and HDMI port at the top one you get the back cover moving..it is a close fit over these ports.

Let me know if you have any other questions..yes I love the performance...please help me to figure out how to get this thing calibrated right.. ;(

---------- Post added at 09:36 PM ---------- Previous post was at 09:33 PM ----------

I am sure/positive that it would make 3 days..did you see that 60%+ of the time on went to the screen..so if I stop fooling with it and use as normal then 3 days will not be a problem at all...
[Motorola Atrix HD] dumon:
Well...there is no magic here... The only basic thing Juice Defender does is shuts down background sync and mobile data when you turn the screen off. So you will not get notified if you have new email or Google talk message until you turn the screen back on or some 15 minutes later when Juice Defender turns the sync back for a short time.

Yes, that saves battery, but for the price of always connected. I used to own another android phone and average battery drain with 3G data always enabled was around 3 - 5 mA in standby. With this phone I see constant drains in sleep mode over 100 mA . This is not acceptable. I could not figure it out if it is some process or simply inefficient 3g/LTE modem.

BTW I am using this phone on T-Mobile, so no LTE here.

Edit: I wish we could have root on this thing and I could remove some Motorola/Att bloatware.
[Motorola Atrix HD] rschwam:
I didn't think it was magic, I'm fully aware that what it's doing is turning off the data services to conserve battery life which means I only have talk/text messaging most of the time. Quite honestly, all I need most of the time is the voice services working so the phone rings when someone calls because I'm at work and don't really need the distraction of the smart phone there.
[Motorola Atrix HD] illmatic.:
I'm very interested in doing this mod also.. I'm sure you've already tried this but have you used a battery calibrating app?
[Motorola Atrix HD] reddog:
Yeap..most of the good ones need root ;(..

Can I ask a favor from the forum members..using either Battery indicator or Battery Monitor Widget app tell me what is the voltage readout when your battery is fully charged. I should have recorded this before I swapped by battery.

I think I may have confused the phone by initially charging the battery outside before installing it.
[Motorola Atrix HD] dumon:
Current Widget shows 4.34V after overnight charge.
[Motorola Atrix HD] reddog:
OK thank you..and that is interesting..the battery is rated @ 3.8V..does anyone know if the 3.8v is a min voltage? Trying to understand the range of change that I should expect..

I am certainly frustrated with myself for not checking all of this before doing the swap..
[Motorola Atrix HD] insanecrane:
Well my battery life is fine. I had JD Ultimate from a previous device and with the extra customizable settings I get a full days use and them some and I'm a moderate to heavy user. As far as it disabling connectivity, the way I have it customized I still get notifications in a timely manner and haven't missed any important emails etc.

JD Ultimate is worth the price, I usually don't pay too much for apps but without it I doubt my battery life would be acceptable. Battery life was my main concern with buying this device as everything I read said it was horrible, but I have no issues with my set up.
[Motorola Atrix HD] darknessrise1234:
Turning mobile data off helps a TON. With it on, I use 300-700ma in idle. With it off, I use 12-120 in idle.
[Motorola Atrix HD] dumon:
I've been using Current Widget for a several days and noticed that once in a while it starts consuming above 200mA in idle mode even with the Juice Defender running and mobile data/background sync disabled. This is the time where it battery starts discharging rapidly.

I've even tried to put the phone in "flight" mode and it would still consume the same amount of power while idling (so this eliminates any radio related power consumption I think). The only way to get the phone back to the normal idle consumption (3 - 6 mA) is to do a reset.

I was trying to identify any process that would consume a greater amount of CPU using Watch Dog app and could not see any unusual CPU usage from there. So I am really puzzled with this inconsistent battery drain.

I know that it could last me around 2 days with normal use when idling current stays normal ( around 5mA on average), so it is definitely some software issue that needs to be resolved. I am looking for any other alternate way to pinpoint the problem with idle power consumption.

Any ideas?
[Motorola Atrix HD] MagicXB:
The battery drain may be due to the software which needs to be optimized, or perhaps due to the LTE modem.
[Motorola Atrix HD] darknessrise1234:
For real optimizing, we need root and cwm.
[Motorola Atrix HD] dumon:
I forgot to mention, I have it unlocked and using it on T-Mobile network. So no LTE for me at all.

It gets T-Mobile 4G speeds though fine. There is not much can be done to fully optimize it without root.

I've disabled all att bloat ware that I could, but the phone is still crippled - can't even switch between 3G or 2G in the settings.
[Motorola Atrix HD] darknessrise1234:
If I keep my data on in an edge only zone, I still use INSANE amounts of battery.
[Motorola Atrix HD] MagicXB:
I'm led to believe that the LTE modem never actually shuts off, even in an area where an LTE signal cannot be obtained. There ate no real settings controls to control/turn off that particular radio. Also, with the Snapdragon S4 the LTE modem is actually on the same 32nm chip (along with Wifi and Bluetooth).

Perhaps Qualcomm could further help Motorola in optimizing energy usage seeing as they custom designed the chip.

[Motorola Atrix HD] darknessrise1234:
Manufacturer? Optimizing? That's taboo!
[Motorola Atrix HD] dumon:
I've just bumped into this post here http://www.qualcomm.com/media/blog/2012/06/20/what-integrating-4g-lte-modem-means-snapdragon-s4-processor-and-battery-life. It says: " The modem is also multimode, meaning it can fall back to 3G when LTE isn’t available."

In any case the very first thing is to get it rooted. This thing alone should be enough to tweak it for a better battery life.
[Motorola Atrix HD] MagicXB:
Agreed, rooting will surely help.

EB40 Battery Mod

I did the mod a while back with a promise of pics but never got around to it, as has already been stated though:

-Simply removed the thin outer housing with a guitar pick run along the edges

-Use a T5 i believe driver to remove the screws around the midframe

-I then used a razor to removed about 1/4 inch or so from the inner top part of the internal plastic frame to allow the battery to sit in proper.

-Seal it back up

ALSO!!! The newest update calibrated my battery perfectly, I would assume its because it will also be what is run on the new atrix hd maxx to be released. I can easily go 30 hours without a charge. FANTASTIC!!! Highly recommended mod

Diff 1-10 = 3

Awesomeness 1-10 = 10
[Motorola Atrix HD] Sonicmax2k2:
Can anyone else speak to battery life improvements since the new update? I was holding off on suggesting this phone to people on AT&T until Moto got a chance to roll out an improvement update. What's the difference you're seeing between the old and new update? Do you use any other tweaks or mods to improve battery life?
[Motorola Atrix HD] MagicXB:
I have noticed some improved battery life. It's not quite what I would like the battery life to be on this phone, but it's certainly better. Currently, I only use Smart Actions to save battery life. I also used to use JuiceDefender Ultimate.
[Motorola Atrix HD] ML417:
I have seen a slight improvement on battery life, especially when I'm not on the near side of signal loss (huge battery drainage because of that). I don't use any battery improvement apps, I haven't seen any signal improvements, but wi-fi still loves to randomly disconnect and reconnect.

EB40 Mod

I have attached a picture of the MOD that I did on my phone. It is not difficult and I can tell you after the recent firmware upgrade my phone is now truly usable.

Take a look at the recent screen shot of my battery life. Yes that's right six days on a single charge. I love it..
[Motorola Atrix HD] souljaboy:
Next guy to do it, please post the disassembly video here, there aren't any on youtube!! :o
[Motorola Atrix HD] smogtdi:
just made mine. The EB40 battery is just slightly thicker.

I only removed the flexible back cover with a guitar pick (that I got with an iphone repair kit)

then I opened the battery space just a bit using a high speed mini drill (dremel type)

I didn't have to remove anything other than the kevlar cover and the battery.

once the battery is out, it's easy to cut open the little part on top. (plenty of space between the part to be cut and the electronic parts.)

no need for a super DIY article to do it.

How to remove the back...

http://www.youtube.com/watch?v=s4zbk4QHA6o
[Motorola Atrix HD] h078:
I got my EB-40 - upgrade went well - no issues whatsoever ... Used Dremel to remove plastic part. Upgraded firmware and fully charged the battery overnight

And WOW... removed phone from charger 7:00 am with 100% , Extra Heavy use during the day (work and personal push email, read a book for 4 hours, downloaded NOVA 2 and NOVA 3 and all the files ~ 750Mb, 1h30min of phone calls , some 30 SMS, web browsing for 1 hour or so, Navigation for 20 min and the phone was on LTE all the time except when I downloaded game files)

and by 1am next day I still had 46% left of the battery life

Now only hoping for ROOT to remove junk apps from the phone... I really feel there is no need for custom ROM as this one performs well but just to remove play books, music and movies and ATT crap...
