Low battery stuck in ap fastboot mode Droid 4 - Motorola Droid 4

I recently encountered a problem with my Droid 4 phone XT894 and got it stuck in AP fastboot. I left it on and hooked up to my computer trying to figure everything out but I ended up killing the battery. Well if you don't know it doesn't charge So with no way to flash my phone to get it working again to charge it and no way to do a battery swap, I Macgyver'd that mofo. I took a fully charged moto droid (the original) battery and used some breadboard pins then I opened the back of my Droid 4 and removed the battery sticker and the little rubber protector and connected the Droid battery to my droid 4 battery and flashed that mofo. It wasn't pretty but it worked in a pinch. I didn't have to ruin anything or buy anything extra.
I hope this helps some of you out there. Remember to observe polarity and you should use a multimeter to check just in case.

Dead Bionic...Not thrilled to be the first..

Hiya...
Rooted/Nandroid with Bootstrapped Recovery..
I was in the car today,device charged about 40%, noticed the Bionic (for the first time) spontaneously booted. Got the boot screen icon, then black.
Went home, pulled the battery, put in the dock, nothing. Battery back in, nothing.
I think I've eliminated the battery as the cause.
Called Verizon, level 2 tech, offered to send a replacement; I opted to go the the brick and mortar store in the AM so as not to wait for 2 days.
Three questions:
Any chance that this is software related? Rooting app or Bootstrap app related? I think not, as in the dock without a battery it should at least start to light up, no?
If I'm correct, am I in jeopardy of voiding my warranty as the phone's rooted? (Not that they could tell).. ?
Anything else to try b4 swapping the phone?
Thx
Alan

No, MOST* smart phones cannot run on AC power alone. They require some charge on the battery in order to boot.
*added the emphasis before someone comes running in because their OG Droid/Nexus One/RAZR/POS flip phone/whatever could run off AC power alone.

Rooting your device may void your warranty. Most of the time if it's a physical problem and not related to software, the warranty will still be honored. However, it'll probably be an uphill fight.

I'd try to get ahold of another battery. I'm willing to bet that yours is defective.
I thought that the Bionic would light up in the dock with the battery removed?

Why would it?
The dock is just an AC charger with a stand.
Try fastboot. Rsd lite. Fxz file

With my Droid X and a dead battery the phone would have to sit about 5 minutes and charge before it would come on at all. Wall charger, not USB via computer.

its true that the bionic will have to charge for at least a couple minuets to turn back on. i have run mine totally dead and it will not power up untill it has charged for at least three to five plus minuets. although it will light up about three seconds after the charger is pluged in and even show the battery pic and charging. first thing you need to do is with battery back in the phone and a regular charging cable pluged in the phone other end, usb, pluged into your computer run adb or what ever you use and find out if it showes any devices at all being connected. you should be able to see this in the rds also. run rds app, then plug in phone using a rear usb port

yep, it's true.
I ran my bionic's battery dry the first day I had it. I was trippin out thinking it was broken or something.
After about 5-10 min of charging, I noticed it had a charging Icon.
I realized that I was upset over nothing.
I put it in the wall charger for the 10th time and noticed after about 10 minutes that it lit up with the boot screen, then the battery icon, which showed 0 percent... then it died. So it does look to be the battery. That's good news, I guess. Should I try to get a replacement from VZW, or spare the cross-exam about rooting and fork out the cash for a new battery?
If you want to spare yourself of the cross exam about root, get a new extended battery. Or if you firmly believe that the battery was defective to begin with, then stand your ground and ask that you be given a new one.
You should be fine taking it in. I would do what has been stated and just get a new battery because if it isn't that then it is a hardware issue and that isn't the roots fault anyways.
Also as a kind of FYI thing, Verizon does not do in store warranty replacements anymore(an exception being if you're within the 14day WFG period and the phone is ruled DOA). VZW, in store, does 5 day(overnight if you have insurance) shipping for free. If you want it sooner, you pay the shipping cost. Further, warranty replacement phones do not come with a new battery. They use the old phone's battery.
Where I'm going with this is always start with the battery in situations like this. That can be warrantied in store on the spot. Also make sure you're going to a corporate location.

Like most cell phone batteries, they aren't designed to be completely drained.
I recommend charging it full, waiting tell it gets to about 10%, then charge it fully one more time.
After that charge, your battery should last you all day.
No need to waste money on an extend battery.

Don't worry, you're not the first to have a dead phone. I had to go get a new one after three days.
Couldn't get booted past Motorola splash through any method, and an unlocked bootloader may have helped. But, in the past, and Verizon was happy to hand over a new one.
Wish I had more useful information, but I don't. So, good luck on getting your beast tamed.

Update...
Went to the VZW store at 9... tech swapped out the battery for a new one. NO GOOD. Nothing.
Probably a good thing, as this way they couldn't void the warranty when they discovered it was rooted
Replaced the phone (17 days after purchase; had to get the mgr to approve a swap)..
Restoring apps as we speak..
Makes one wonder what's up with Motorola's QC dept.

Overheating issues?

I just (10 min ago) went to check the time on my phone, and when I grabbed it, it was extremely hot. When I turned it over (I put it face down at night so the notification led doesn't bug me) it was showing the battery charging screen except it was a question mark. The phone was plugged in since 10 pm (its 5 am now) and when it had cooled down enough I turned it back on and it said I only had 50%, even though it had been charging all night. Has anyone else had similar overheating issues, and should I return it for a new phone?
Sent from my XT894 using xda premium
Tried a hard reset? If ao, return the phone is what I would do. No way its supposed to drain that quick or heat up. Charging, navigating and playing music over BT and my phone is warm, not hot.
Had a similar issue about 3 weeks ago. Wasn't plugged in charging though. It was just sitting in my pocket. I thought it felt warm against my leg so I pulled it out and the phone was super hot! Turned the phone off immediately, let it cool down, and it hasn't done it since.

The other day I was charging (stock moto AC charger) my battery (40%) and downloading stuff via 4g and mine got to 46 degrees C. I slid open the keyboard and put it in a opening of a vent that was blowing 60 degree F air. 1 hr latter battery was 80% +/- and i dl'd more stuff.

You said there was a battery with a question mark. Was your phone booted up at this point, or were you in the 'battery charging mode'?
Sounds like the phone overheated, which can sometimes happen. You could try to get a replacement, but unless it happens consistently they might give you trouble trying to return it.
The annoying thing is, they say our batteries aren't supposed to be removed. It was nice being able to swap in a spare when my wife was done with her A855 moto Droid and same with having a "spare" incredible...
Anyone know the reason they made ours not come out?
Sent from my DROID4 using XDA
It is my understanding that they used a special type of battery to get it so thin. The downside to this special type of battery is that they are easily bendable, but explode when bent
As a result, they don't want anybody touching the battery and exploding themselves.
Somebody who is more knowledgeable in battery tech could probably give a better explanation.
Couple weeks ago I was using the GPS and had the phone on the Motorola cardock while plugged in (with a Verizon charger) to the car. Took the phone off to make a call and I literally couldn't touch it. I kept it on the side and opened the battery doctor app, told me the battery was 58C. Immediately pulled aside and turned off my phone. Stupid phone has the locked battery door also so I couldn't pull it off to let the battery cool faster. Worst battery door design by Motorola.

[Q] Droid 4 Battery Questions and answers

Picked up a droid 4 a couple months ago, the battery life always seemed crappy, but then again I run my phones hard (hotspot, etc) then one day it went down real quick, and wouldn't charge. Already did my homework so I knew the screws in back were the positive and negative terminals. Checked the voltage, it was way low, like 3 or lower. Busted out my B6 charger and was finally able to get the thing charged, but it drained retarded fast. Someone was selling a D4 w. the battery removed on craigslist for 60 bucks, so I snagged that, turns out the battery was severed at the cable so I still got no battery, but I Do have a spare D4, so I start troubleshooting. Turns out with my old D4, with any battery connected to it, would start draining at half an amp. Starting up it hit 1.25+ . at that rate the phone would be dead in 90 minutes. The Other droid was more reasonable, .6 or 7 at start up, and .2 baseline. I Ended up Modding the second D4 to run off a couple 18650's I had. IT works, and ran forever but I just snagged a couple LiPoly's that will shrink the case some. Anyone got any ideas why the original phone is draining batteries even when off? Anyone here swapped batteries on the things?
its a (suggested) non removable battery for a reason lol
yea because then they can make it xXX .XX MM Thinner, due to not having to ruggedize it at all (to prevent flexing). If they had put a decent one in there in the first place I never woulda removed it
Pictures of this mod? What are you using for casing? Which Li Poly did you go with? RAZR max batteries?
My wife came home today with her battery completely drained today and she is a light user. Ota ics causing this?

Droid 4 Won't Charge, Stuck at 0%

I bought a Droid 4 off of fleabay in the hopes of resuscitating it. The phone is in perfect condition and no water damage, but when I plug it in, the charging splash screen comes up and stays at 0%. I have made sure to use a motorola charger and cable, supplying the proper amperage and left it plugged in for 8 hours in case of deep discharge. The only thing I can get into from the power&volume-+ menu is fastboot, but it says the battery is too low to do anything.
Do the Motorola factory cables work to power the Droid 4 in fastboot? Everything I have read says they don't work for the Droid 4. Does anyone have any other suggestions to bring this thing back to life? I'm wondering if the battery is just defective.
I fixed it! I couldn't find any Google results for this particular problem so hopefully this helps someone. If your Motorola Droid 4 is not charging and stuck on the battery icon with zero percent displayed, a Motorola "factory" cable will likely fix it, if the battery isn't dead. I used this thread to make a factory cable: http://www.droidforums.net/forum/droid-labs/146492-how-why-make-your-own-motorola-factory-cable.html
As soon as I plugged my frankenstein cable into my PC, the phone booted right up. I scored a Droid 4 in perfect condition for $50 on fleabay, and now it works! yay
Good job, that's awesome!

[Q] When phone is off charging battery has question mark

I've had this phone for about two weeks now (I bought it used). When I got the phone the battery lasted pretty much all day for about 4-5 days. Then I pretty much started having charging issues. When the phone would fully die it would lock up. Sometimes when the phone had 80% battery it would lock up and stay that way for about 30-60 seconds. It would then reboot possibly lock up on boot for another 30-60 seconds, then if it did come on the battery would have an explanation mark telling you it needed to be charged. Now sometimes when you go to charge the phone it would turn on but have a question mark inside of the battery instead of where the colors are while it's charging and off.
I tried to purchase a battery locally and replace it. This battery does the same thing. The phone will boot for a bit, charge, then shut off. When I go into fastboot mode it says 'battery low'. When I got the phone and started having problems it was still stock everything, no root. Now I am running Youngunn's HoloBlur performance edition and the battery I tried to replace it with is an EB40.
The questions I really have are this.
1- When a battery is bad does it cause the '?' mark
2- Does the EB40 have to be calibrated some how, or does the ROM just pretty much know what's up
I don't really want to drop another $50 into a battery if that doesn't the issue. However in my past experience and knowledge of electronics and phones it seems to be the battery.
Thanks in advance!
have you tried a battery calibration app

I can't really get that far into the phone. After I get the phone booted it says low batt then goes through the power down process
Update: After reading a few threads on this site and others I've heard them all talking about using the OEM charger. I was using the USB brick I use for my Samsung tablet 5v 2a. I've just found a moto charger at my house which is 5v 550ma and the charging meter is now going up.
Thank you for searching guy.

You're welcome man!
I took the battery that I purchased back and ordered a new one off Amazon. I put my old battery back in the phone and left it alone. After the phone charged for two hours it said it was at 25%. I booted the phone up got about five mins of use out of it and it locked again and wouldn't turn back on. When the phone isnt on and just charging, does it use the ROM to display the battery charging meter?
Here's another update.. I got the new battery in and put it in the phone. I tried to power it up just to see if it had a charge and it displayed the unlocked bootloader logo and shut back off. I then tried to plug it into, still nothing. I eventually got the green light on the top to show up. At first it was blinking, then it went solid with a very small blink. After that, still nothing.
I have tried using a 5v 500ma, 5v 1a, and 5v 2a charger and still nothing. Does anyone have any ideas?
You used the stock moto charger?

I went to ATT and tried to get the OEM charger from them but they said they didn't have one. They were trying to use a 5v 1a usb cord with a block on the end. The only actual Motorola charger I have is what I got when I had my Atrix 4G. It's a 5v 500ma...
What is the voltage / amperage on the OEM charger?

I have never used the original Moto USB charger. I usually use anything that was convenient and that includes my, laptop, desktop, HTC, LG, and Samsung USB chargers.
Same here. With any of my devices for that matter. Usually the phone can dumb it down or just not charge.
Sent from my GT-P6210 using xda app-developers app
And sometimes that's fine but If it won't charge first thing to try is the factory charger to rule that out.
Sent from my PACMAN MATRIX HD MAXX
After going up to the ATT store and getting them to try multiple adapters it still isn't working. I have noticed that when you plug it into the computer it recognizes the phone.. To what extent I have no idea (since I only plugged it in for a minute at the store). There are also times when you plug it in and the green light will be flashing, and other times the light will be solid.
Like I said this is straight puzzling. The phone worked fine for a few days with no issues. It seems like it got wet but there's no way it could have.

This is a hoax. Battery calibration is not real (Words from a google/android employee). All these apps do is maybe clean up the battery statistics so android builds new ones (which it does by itself in the long run anyways). This process has nothing to do with the actual battery/hardware.
That's all they're meant to do. Wipe the stats so it will get a correct reading.
Sent from my PACMAN MATRIX HD MAXX
Did you solved it?
I had the same issue ..couldnt fine a workaround uptill now
*facepalm
Solution:
1.Take out your battery.
2.See those contacts between the terminals? Yes, they're the battery sensors. If they're not in contact with the base plates on the phone board, do something about it. I don't know what, you decide.
3.get some naked wire and create your own screw washers, for the terminals. Screw them under the screw, between the battery board and base screw holes.
4.Tighten properly.
Done.
Now, try again till the charger accepts that your battery is existent.
You are welcome.
