Well, I just died with 15% (according to that app). I think the minimum voltage needs to be raised.

Also, right now it says 62% when the phone says 14%. However, it is charging, which I assume causes the voltage to raise. I would still charge until the phone says 100%.

I'll see if I can find a minimum voltage that is correct.

The inner machinations of my mind are an enigma
[Motorola Atrix HD] fbedros:
Please keep us posted. I just did this mod last week and so far it's great! I'm curious to know if I should now use a battery calibrating app...

Thanks!
[Motorola Atrix HD] jaweinre:
battery calibrating is a hoax, this has been discussed several times and clarified by a google android employee.

You're not actually calibrating the battery, you're just generating statistics which the OS uses to calculate the amount of battery life left the phone shows on your screen, among other things i assume.

That's why some people get that "i have 1% left and the phone won't die" feeling, you switched bateries so the phone needs to generate new statistics to learn what number to display. Cleaning battery stats on recovery mode is not even a necesity since these statistics are generated over and over and the new ones will overwrite the old ones eventually.
[Motorola Atrix HD] Silentwidow:
I found that the battery calibration didn't really do anything for me, I found that after a few days, the hardware took care of it, now if I flash a rom, the battery stats don't seem to get messed up, my battery lasts me about 50-70 hours with regular use, maybe 8-9 hours screen time, if I am traveling, the Navigation will take it down to about 20% in 6 hours of Nav time. Though, with the new maps update that dims screen that will go up I'm sure :).
[Motorola Atrix HD] Gambrinus74:
So what is the trick? Mine still runs forever on 1%. Should I let it run out a few times or does it take a while?:confused:
[Motorola Atrix HD] TecknoFreak:
After doing this mod somehow the loud speaker is not in contact and i have no sound. Any tricks for this as i have opened mine 3 times already and still no sound but if i press the phone on the corners sound comes telling me that speaker works
[Motorola Atrix HD] KrisM22:
bend those little prongs up slightly? (right red circle)
[Motorola Atrix HD] TecknoFreak:
Yeah i did but battery is just slightly too thick. I fixed it adding just a little drop of hot glue right below the speaker contacts, good to lift the contacts just a bit.

That did the trick
[Motorola Atrix HD] KrisM22:
Where is the hot glue put? Also see post #51
[Motorola Atrix HD] TecknoFreak:
Use your picture to the left and below the contacts i added just enough to make the speaker raise just a bit. (do not glue it)

Just try but without doing this at first ok. It should work. My situation is a bit different because first it got wet and then i dropped it few times
[Motorola Atrix HD] KrisM22:
okay - I just ordered an OEM EB40 out of Calif so will give it a try. I will probably cut the plastic to reduce pressure. It's great that this thread (I'm reading the whole thread) warns you about the speaker so one can take steps!
[Motorola Atrix HD] TecknoFreak:
Yeah i got it from the same people

---------- Post added at 01:14 PM ---------- Previous post was at 01:08 PM ----------

Ahaaa i missed that part thanks for bringing it up. I just won an Atrix for $10 including shipping on mint cosmetic looking but it doesn't turn on. So will mess with that one instead of this one as mine is all dented and scratches everywhere. Lol
[Motorola Atrix HD] KrisM22:
toys!

Is the EB40 battery longer or same length as orig EB20?
[Motorola Atrix HD] TecknoFreak:
Same length just a bit thicker
[Motorola Atrix HD] KrisM22:
good - I just cut the bezel to the length of the eb20 so it's ready for the eb40 to just pop in. I also took a ton of pics to satisfy anyone who wants. will post when get.
[Motorola Atrix HD] KrisM22:
Uh, it's

TWICE

as thick and about 3mm shorter. The back looks like it won't fit, but it does. You HAVE to cut the inner bezel.

1 took it apart, laid battery on top of bezel to pencil a cutting line.

2 remove bezel.(10 screws)

3 cut bezel. This was not pretty to watch... :D

4 re-assemble.

Battery came in nice stapled plastic package with torx driver.

Got from http://www.ebay.com/itm/161243331498?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Battery said 77% when inserted so power off and charge with wall wart and within maybe an hour was 100%. (this causes android to clear the battery stats.)

It dropped fairly quickly to 99% and then 98% because it had not sat for a while on 100% with the charger.

I had to hammer it with benchmarks and stress tests to get it to 93%. Battery only got slightly warm.

I'll just leave it on 24/7 with wifi, BT, and location running.

Since it's only double the capacity I expect only double the run time.
[Motorola Atrix HD] TecknoFreak:
Nice bro, I did exactly that on cutting the bezel.but for some reason it will not close nicely on mine from one side. I got mine from a seller from Cali but they are used on great condition for $12
[Motorola Atrix HD] KrisM22:
Ahhh you just need a bigger hammer!!! :p :silly: :D

EDIT: when I'm replacing the bezel I have to pull out on the area near the sd/sim cards, and pull out on the area near the power and vol buttons to get it to fit over the cards and buttons.
[Motorola Atrix HD] jjmai:
Anyone know what that big white sticker on the bezel is for? The one near the top right corner of the battery.

Is that water damage indicator?
[Motorola Atrix HD] KrisM22:
The "big white sticker" covers a smaller clear plastic piece which covers the indentation and hole through the bezel next to the speaker. My guess? it's dustproofing the speaker baffle port. But I really have no idea what that hole is for. I removed mine (white sticker/clear plastic) and replaced it in the

same

position and laid it down with the edge over the battery.

Need EB40 Battery in Pakistan

Hey thr everyone, i desperately need the Moto EB40 battery for my Atrix HD. I've searched everywhere in Pakistan but can't get one :( Help me out to buy it from a secure seller who can actually ship to door, i previously bought some items from ebay but none of them were shipped to my door.
[Motorola Atrix HD] treefrog20012003:
If not to your door then where do they go? I find it hard to understand that it does not get to the proper destination. I bought the Chinese equivalent but it's not as good as the Motorola original.

[Motorola Atrix HD] Arjomer:
We have the same problem... The battery can't ship to my country. :,(
[Motorola Atrix HD] KrisM22:
Bad form to use XDA forums to try to bypass your country's customs. Please don't.
[Motorola Atrix HD] treefrog20012003:
So back on topic, I was dumb enough to buy the Chinese "same as original" battery and can't get it to calibrate. I've tried everything I could find here, Google it, and still cannot get it to calibrate. Besides buying the proper one, any suggestions? I'm sure it will come down to me buying the original EB40 in the end.
[Motorola Atrix HD] KrisM22:
My guess is that the China non-OEM version is probably okay - especially since the OEM ones are also made in China.

afaik there is no such thing as "calibrate" - that is a myth that has been around forever. Charge it to 90% or more and the battery stats will be reset(that's an android thing in KK, and probably in JB)(but NOT in GB), and it will do its thing. I would power off, charge overnight (so it gets to 100 and sits there for a while), and then use it. It shows a battery percentage based on the voltage, afaik. I use no special battery program. (only betterbatterystats when I need to track down batery usage, although I find that settings / battery is sufficient.)

Be aware that if you power off your phone, or plug it to a computer or wall wart, while the battery percentage is 90 or above, it will reset the stats. THAT DOES NOT NEGATE THAT IT JUST RAN ALL DAY . The percentage will remain the same. If you want to power it off overnight, simply write down what the duration is so you can mentally add it to the total use duration. Or you can just leave it on overnight as some folks do, so the stats won't be cleared. I note the number of hours and power it off overnight cause I hate to waste.... :D

"the stats" shown in settings / battery - are just to give you a sense of who's using the battery, and how many hours you get out of a charge. It does not control android in any way. Android does not "learn" anything about battery stats. Android writes info to that file
[Motorola Atrix HD] treefrog20012003:
I've ran the phone dead twice, did a full overnight charge, powered on once it charges to 5%, and then left it charge all night. Today it was a lot closer than Sunday. Sunday it ran at 1% for six hours playing games and music. Just can't get it to be the same from day to day. Maybe it's the phone I did get it used. I've also ran different kk roms to see if it made a difference. I did install them at 100% charge plugged in and after install I unplugged.
[Motorola Atrix HD] KrisM22:
It could be that the battery does not get to a sufficient voltage, and thus percentage. I did read through most of this thread and saw one person who had different results with different chargers (wall-warts, I believe).

My phone was used. My wallwart is a Huawei (I wonder how I got to use that???)(from my old Huawei Prism!)( 5.0v at 1.0amp) and the cable is an OEM Sammy . I would think plugging it into a computer and letting it sit there would be good as well, if you question your wallwart, though you'd have to leave your computer running.

These parts evolved as I actually had one cable go bad - when I plugged it into my computer it would BSOD. So tossed that one. Apparently I did not try to buy a new Moto wallwart and cable when I ebayed this phone.

For wallwarts and cables I do try to get some mfgr's OEM part rather than a generic one.

The ROMs will not make a difference, except for Carbon KK unified msm8960 which will not charge from power off state. - at least when I was using it.

I do believe you get a better charge if you charge from power off state, but that may be simply a myth that I have developed! :D
[Motorola Atrix HD] djd100:
Thank You All...

I just finished the Atrix HD/EB 40 battery mod and all is working great.

I unscrewed the back and used a Dremel to cut the plastic away where it covered the battery, and there's just a little back separation around the power switch and volume control which is hardly noticeable, and the rest of the case/back seam is perfect.

I used a supposedly new Motorola EB40 from "ismartone" on EBAY (can't post a outside link), so hopefully I'm good to go.

Thanks again to all for all the hard work everyone!
[Motorola Atrix HD] pijes:
don't forget to share your screen on time and which rom you're on.
[Motorola Atrix HD] KrisM22:
yes, there is about a 1mm gap by the power button/vol button. The rest fits tight.

---------- Post added at 09:44 AM ---------- Previous post was at 09:43 AM ----------

"a bunch (gobs) of hours and some percent..." :D

Validus ROM

The use you get depends totally on what widgets you use (weather, etc), and whether you run BT, wifi, location, etc as on all the time. So this number is rather meaningless. I run beweather, BT on and the rest off so I get a bunch of days. Screen on percent of battery used usually is someplace around 60 (70%?)or so - it's the big battery eater. Android always has quirks - after an install, I shut off location the other day and only discovered later when my battery was at 29 that GPS was still going per settings/battery/press on graph. - LOL - should have power cycled! LOL

question about the batterie mod

okay first let me thank you all when i first found xda i knew nothing of anything now im still a beginner but am learning im on my forth android phone rooted with custom roms this is my first motorola phone and i love it the bloatware stinks but i am still learning so my question is with this battery mod ive tried to find the specs on the battery in question and only thing ive gotten is eb40 for razr max so i ordered this one from new jersey can anyone tell me if this is a good choice they say its brand new and comes with a 36 month warranty the specs are Voltage: 3.8V

Capacity: 4000mAh

Battery Type: Li-ion
[Motorola Atrix HD] treefrog20012003:
4000mAh? That sounds a little big. I wonder how thick it is? I bought a 3300mAh Chinese equivalent and I think it was a little too thick cause mine won't close properly. I'm actually thinking of buying a used eb40 from a max just to see if there is a size difference.
[Motorola Atrix HD] KrisM22:
Read back a few posts - the

OEM

EB40 battery is

TWICE

as thick as the original EB20. I do not know about these other batteries.
[Motorola Atrix HD] treefrog20012003:
That's the point I was trying to make, the eb40 is twice as thick so what's a 4000 going to be? I have the Chinese 3300 and I think it's thicker than the eb40
[Motorola Atrix HD] KrisM22:
Hey treefrog - did you get your battey going?
[Motorola Atrix HD] treefrog20012003:
It's been in for a while but it still won't calibrate properly. Some days I run 6 hours at 1% other days it almost right on. I need a new body and battery cover cause I had to take it apart 3 times and busted some of the clips. Other than that it works great. Because it's so thick the body had to be cut out. I suppose that's why it won't close good. TPU case hides it well.
[Motorola Atrix HD] souljaboy:
Download a battery calibrator from play store. It should ask for SU and then delete batterystats file. It has two buttons next to each other on the main screen and displays the mV in pretty large. After that you can uninstall it.
[Motorola Atrix HD] KrisM22:
And the myth goes on... Just delete:

/data/system/batterystats.bin

if you want to.

That happens automatically when you plug/unplug or power cycle at 90% or above...
[Motorola Atrix HD] KrisM22:
no such thing as battery "calibrate"

Are there any protective cases that no longer fit after the battery mod?
[Motorola Atrix HD] orangeisnon:
I own both the Ballistic SG MAXX and Trident Aegis, and they both fit. With the Trident, the volume buttons get tricky (the rubber slips off and you click nothing), but removing the back plate of the phone fixes this.

The SG MAXX (the same as the SG, but with a "rigid" screen protector (not that rigid) and belt clip) works perfectly fine. I still have the back off from when I used the Trident, but you could probably leave it on. The screen protector also doesn't stay in correctly. The belt clip works great.

Hope that helps.
[Motorola Atrix HD] treefrog20012003:
My favorite case featherlight does not fit. When I put it on I get "water" marks on the screen. Guessing the LCD touches the digitizer. Going to buy another body and battery door and see if I can thin down the battery just a hair. There was a piece of plastic on the battery that may be adding to the thickness of the Chinese aftermarket battery. I like the mod so far it's nice to go all day without a charger.
[Motorola Atrix HD] souljaboy:
I dont know man, first time I put the eb40 in my phone was randomly turning off at 5% and above it, got me seriously worried. It took a few cycles to find itself, although I did take it apart and re-seat it a couple of times in the process.
[Motorola Atrix HD] KrisM22:
a) LOL - go argue with those authors! :laugh::laugh: That is good enough for me, but I know there will always be a number of folks who pray to the god of "calibrate" - and propagate that myth - especially just as long as there are cheap ebay batteries... :D

b) any new battery that has not been initially charged at the factory (and thus tested)(my OEM one was charged), are likely to show any number of anomalies! :D:D (like bad or weak cells) - just my humble opinion. LOL Where do you suppose the factory "fail"s wind up?

But I notice this is one of the big topics on the net - cheap batteries that don't work and folks trying to find a reason... - again - LOL!!!

I guess they're hoping there's some program logic buried in android that pretends a battery isn't bad. LOLOLOLOLOLOLOLOL

Okay, and my 2 cents on "guarantees" - consider the cost to you to ship it back with tracking, and the time delay,

assuming everything goes perfectly

. There are good dealers on fleabay, and bad ones. The brain in your head has to determine your willingness to take a risk, or just "you want a good product now".
[Motorola Atrix HD] Gambrinus74:
I have had the EB40 for a while now. I have done the battery recalibrate and it did not help. I've just got use to it. I just have learned that my phone can go about 6-8 hours on 1%
[Motorola Atrix HD] treefrog20012003:
I found for me running it until it dies a few times, then I know about when it will need charged. So far I can go from 5:30am until anywhere from 9:30pm-10:30pm. And that's with fairly heavy use. I wish the programming could be modified to accept the difference in battery but it can't and I had hoped android could adapt to a different battery but it can't really.
[Motorola Atrix HD] KrisM22:
The problem is with the battery - weak or dead/shorted cells. If a cell is bad the battery won't get up to the full voltage. The cells within a battery (correction) parallel, charged to 4.2v EDIT: max 4.2, avg 3.8, zip 3.0 - roughly.
[Motorola Atrix HD] Gambrinus74:
If it's got a bad cell I would hate to see how long it would last. I'm getting almost 40 hours
[Motorola Atrix HD] KrisM22:
I'm at 2 days 21 hours at 65% for this particular charge. Of course individual usage will determine life, given the same battery.

The Qualcomm PM8921 power management chip is what controls the charge for the Atrix HD.

Well true to that. Lol
[Motorola Atrix HD] treefrog20012003:
After a few days running the thing completely dead, as in shut down and won't turn on, I have discovered that the battery is now taking longer to charge, and the battery meter is almost dead on. I guess it needed to break in. Love playing games, texting and surfing the web all day. I'm holding steady at 17 hours before needing a charge. If I didn't play games I bet I could make it 3 days
[Motorola Atrix HD] KrisM22:
yeah, game playing... :D

So how high a percentage do you get now when fully charged?
[Motorola Atrix HD] treefrog20012003:
It only says fully charged, 100%. Takes a while now though. Roughly twice as long. First few days it would say 100% only and never charged so I ran it from full to shutdown for three days and now it works great. I think each day it takes more to get to 1%, tonight I'm still at 27% and normally I'm at 10% or lower since I made this mod.
[Motorola Atrix HD] KrisM22:
Definite improvement!!! Great!!!
[Motorola Atrix HD] treefrog20012003:
Yea, I expect that over the next week I should see the battery peak at its full potential and then the degrading of the battery will begin. I want a bigger screen phone but I don't want to give up this battery life. I go camping with the boy scouts once a month and this battery is going to come in handy for that.
[Motorola Atrix HD] KrisM22:
definitely better than the original eb20!
[Motorola Atrix HD] jaweinre:
I recall the first rule when camping with the boy scouts was giving up handwatches/cassete players etc (we didn't have cellphones back in that time)... Wtf happened?:silly:
[Motorola Atrix HD] treefrog20012003:
Well that still holds true if your a scout, but adult leaders are expected to carry a phone for just in case. That's why I did this mod to make it through a weekend without access to power. And that's just on standby not even using it. Without this mod my phone was dead within 24 hours with everything shut off except calling.
[Motorola Atrix HD] KrisM22:
In that position I would leave mine off unless needed. Or maybe they require it on in case of calls coming in to warn of sudden weather alerts or etc? I would also carry a powerbank type unit. but then I'm paranoid! LOL
[Motorola Atrix HD] treefrog20012003:
The weather alerts, parents (emergency either way) and scout emergencies are why I needed this mod. A power bank sounds good until you start to worry about weight limits and space. Most charging packs are not that big anymore but it's still another thing to pack. I lab on doing a 48 hour run not using the phone for anything but text and calls to see how long it will last
[Motorola Atrix HD] KrisM22:
I bet 4 days plus for text and calls...

EDIT: I am currently 52% and 4 days, 1 1/2 hours. I run BT but no wifi, location, or weather widget (just turned on BeWeather)
[Motorola Atrix HD] treefrog20012003:
So has anyone found any apps that are battery robbers? Swype drains my battery fast, at least an extra 20% a day.
[Motorola Atrix HD] jaweinre:
Check with wakelock detector.

In general, i've found the google keyboard (not the aosp one) to drain because of wakelocking my device. Swype used to drain too so i removed it and just use aosp keyboard that comes bundled in CM. It's got swipe functionality and works pretty good IMO.

The other drainer is location from google play services, it drains by attaining location which also means wakelocks. you could disable the whole thing if you don't need it.
[Motorola Atrix HD] KrisM22:
Just about any weather widget except the included weather in news and weather. Probably most any widget. BeWeather widget seems best but seems to use 6%/day but it's tough to gauge as battery drain is non linear by percent.

By far the best browser is Opera Mini in term of battery and data use. I use My Data Manager to monitor data, and Android Firewall to block things like Google Play which likes to blab. I have a 200mb/mo plan so I am very attentive to data. ($40 ATT paygo gophone)
[Motorola Atrix HD] KrisM22:
After I turned on BeWeather(set to update on "phone unlock"), which I believe is about the least battery draining weather app. On the next charge at 51% it's 3 days and 13 hours. So adding that one app costs about 15% in battery life. Rather amazing...
[Motorola Atrix HD] treefrog20012003:
Ok guys i love the extended battery but my favorite case no longer fits cause it's a form fitting. So I'm buying another battery that's eb20 compatible. Once i have my new battery I'll sell my 3300 to anyone interested. Shoot me an offer all i can say is no.
