I need help. I messed up my Droid 2 restoring a backup and the battery died during SBF. So I did the Macgiver trick where you connect an old stripped usb wire to the battery so that the phone can be tricked into booting up and being flashed. Since then I've had a question mark in my battery icon. It wont read that battery or the battery that I've just purchased and I get the "Invalid Battery" message and the battery wont charge in the phone. Both batteries are official Motorola. I can't send the phone back as its not under warranty. So I have a few questions.
Is the some sort of workaround/ fix for this? Motorola put software on the Droid 2 since Froyo that reads whether or not a battery is official Motorola product. Can the battery software be hacked/ deleted so that I can use my battery as normal?
Wow, we have this same exact situation like a month ago, and since then my fiancee still uses her broken phone . We did the Macgyver trick also and we got the battery with the question mark. We even bought a new battery and it still shows it, tried reflashing with a fully charged battery and nothing changed. We also tried clearing battery stats none of it is working. If anyone knows anything about this problem please let us know. If you get an answer that cures your phone please please please let us know about it. I actually posted your question on Yahoo! Answers since it was the same exact problem that we had and if anyone answers we will post the reply on here.
Thanks a lot and good luck!
I've got the exact same problem. All I did was purchase one of those external chargers so that one battery is always charged. It is annoying, yes, but its not too bad. I'm also looking forward to see if there is a solution, but I doubt it. We probably all fried the contacts on the phone, but we'll see.

hey, yeah we did the same thing, we bought the second battery yesterday but i have a question, did you try flashing it again with the new battery in? I was wondering if it would work but i want to see if it will before clearing one more time my fiancee's cellphone since theres a fish game that may be lost if we do that.
Thanks a lot.

I've SBF'd multiple times since then, and the question mark is still there. I don't think theres a way around it, unfortunately. Personally, it's not really a big deal, but it may be for you.
I just really hate it because I have no clue when my battery dies.
Never had the issue, but one thing comes to mind..why not root, install clockwork recovery and then clear the battery cache?

They said they already tried that.
What exactly is this Macgiver trick? If you have a link, or some info on how it's I might be able to shed some light on this for you guys
The D2 battery is 3.7 volts; USB is 5. You probably blew out the A/D channel used to measure battery level.

Ah, I see so they're hooking up the USB straight to the phone...found it after a little searching...
But i'm curious, wouldn't that only happen if the wires ended up touching the other two terminals, and not just the outer (+) and (-) ones?
Will getting a new oem battery work?
No, replacing the battery will not work if you messed up when connecting the spliced USB charger + and - to the wrong terminals in the phone.
I have exactly same problem. I sliced the usb cable to revive my Droid X when the battery died during sbfing. Now my phone survived but Im stuck with question mark on battery icon. I flashed reflahsed and flashed again but no luck. wiped batt stat but no luck. Tried new OEM battery, no luck.. Put the batt in the freezer for 10min but no luck. I ran out of all the possible solution.
Now I just got the external stand along batt charger from ebay with 2 extra batts. I just carry extra battery since I dont know when the phone will go dead..
I would love to find out if someone can fix this issue. I still got 6 mo to go before I can upgrade.
I HAVE A SOLUTION (worked for me):
When doing the "Macgyver Hack", I jammed the USB wires into the battery. This pushed the metal spring terminals out. After that, the battery terminal springs don't all touch the connectors in the phone.
Take a needle, and carefully pull the battery's metal springs toward each other.
This worked for me.
Also, try this:
Remove battery and unplug phone. Plug phone in (without battery), then turn on (some phones will turn on without a battery). After the logo comes up, insert the battery. This made my phone recognize the battery and get into the OS.
Once the battery is recognized and you can boot to the OS, root the phone and get the battery calibration app (and use it).
I have a Motorola Defy, and used the Macgyver hack, then had the question mark problem for days before figuring this out.
jodaboda, Thank you a ton for that. I've been searching and trying out things to fix this and this is the closest I've come.
Although the Droid 2 doesn't boot up without a battery, I've had to the Macgyver Hack to get it to boot. The battery calibration app reads 100% charged when I am using the Macgyver Hack and is showing that the battery is charging. I'll tell you if it works once my battery is charged and I calibrate.
I wasn't able to get it to work. I think there is potential but my phone eventually died and it wasn't able to fix it. That app can measure the volts correctly tho, which means we should be able to get the battery working again somehow.

I don't have a nan back up from recovery but have read on another thread that you can also fix this by doing a restore of a back up through the recovery from a time before you have had the battery ? issue.. several people have also mentioned that it worked for them.. in my case I don't have a back up before this issue so I cannot confirm.
my phone died noooo
bumping in case anyone has a solution?
please. pretty please.
tried methods above, phone wont boot unless plugged in... i don't care i can't tell what % its at, but i do care it wont boot off battery power.
Tried 2 Ways with no Luck.
1. Power button + volume button down Long press less than a min. ?
2. Plug in for a day or more. ?
Gotto try jadaboda's tip.

Hi, I have flashed my phone into the Nighty CM7, I finished setting up and restoring my apps, then I wanted to boot into ClockWork Recovery so that I can backup my rom.
However I ended up with a dead reboot, its stuck at the M Logo. I waited till my battery died. I charged the phone for a night, and I ended up with the big battery sign with a QUESTION mark in it, the light beside the USB Port wont let up.
I connect it to my computer using the USB Cable, the Light beside the port lit up, but it wont charge nor boot, I tried to put my phone into RSD Mode so that I can flash my stock rom again, however it says "Battery Low Cannot Programm" and turns back off. I cannot put it into Recovery Mode by holding x and the power button.
CAN SOMEONE HELP ME? I CANT USE MY PHONE?

Ok, to be honest, this was stupid. Your first step is now get battery charged.
You have following options:
charge it in alive Milestone 2
charge it in some universal battery charger
charge it via wires (yes, it sounds risky and definitely it is not too good for battery life, but someone here successfully done it) - manual attach wires with coresponding voltage and give it few minutes - only to hold charge few minutes for RSDLite... Or you can maybe bypass battery and put wires directly on phone - but this is really risky and I dont recommend it.
Of course - best option is #1 or #2... But you can't do anything without charged battery...

it doesnt work when the battry is charged charged, thats why i waited till the battery to die untill i start over again. I have looked online and dont think this is really a battery problem~
Look at here http://forum.xda-developers.com/showthread.php?p=19197228 - I think it's the same situation. You have to charge the battery to use RSDLite.
tl;dr Low battery = "Battery Low Cannot Program", charged battery = "Battery OK / OK to program" in RSDLite.. so...
sorry, how am i suppose to charge it? it wont charge, so i need a battery charger instead of charging it through the phone?
Yep, you can't charge your battery (in your phone) when you have bricked phone (thats why I said it wasn't good to let it die, because now you have one more problem - how to charge this battery)
And I wrote how to charge it in my post #1 - basically you have two options: universal battery charger (charger, where you put battery and it will charge it) or another (working/alive) Milestone 2...
great i got another ms2's battery to boot into recovery mode (rsd mode works too) thanks, i am a noob
No problem man, everyone makes mistakes time to time
It's good to see it solved and alive
well its still sbf-ing, one thing i notice is that its taking longer than usual, but i think it will work, thanks again
Your lucky then! I don't know anyone with an ms2 so had to go macgiver style and charge the battery directly with wires. I swear the battery has never been the same since, although every battery/system tool claims the battery health to be "good"

Maybe you should download battery calibration app?

If you're refering to me - I've done that already and no luck
I've tried every trick on battery calibration I've found on this site and google searches and it never shows any noticable improvement.
So now I'm just more vigilant with battery saving tricks
Thanks for trying to help either way

Hey guys...I have an Atrix4G running android 2.3.4, my problem is that when I plug the phone to the pc to transfer files from SD card with an USB cable it starts charging..I can`t find the setting on the phone that it allows me to disable it...if that continues on im afraid I will have to get a new battery..Solutions anyone?
Thanks in advance.

Why would you want it to not charge while plugged in to the computer? Are you able to transfer files? If not should be an option in your notification bar.

Cause it mess up my battery...its gonna shorten its health, I used to own a HTC and on that one I could just tap on the battery bar up right of the screen then I could choose to stop it from charging when connected to the pc but I can`t do the same on this one..I can`t even find something about the battery besides putting it modes...nighttime modes..performance, Maximum battery saver and custom mode which also does not have a option for stop it from charging when connected to the pc..
P.S. I can transfer stuff fine from the SD card, like I said problem is I don`t want it to charge the phone while connected to pc.

How will it mess up the battery? Lithium ion batteries do not suffer from memory like lead acid, there is software to prevent over charging, and the batteries have a certain number of charge/discharge cycles in which partial cycles count as partial cycles so there really is nothing to fear from charging your phone.
If you really nfeel your hurting your battery don't let it sit on the computer.
PS. Even if my answer does not satisfy you consider it a free bump

Hey guys,
I noticed this yesterday my Nexus 4 (running PA 3.6, franco milestone 1) shut down at 30% charge. I went home and charged it (it showed 0 when I started charging it) to 100% continuously.
Today too the phone shut down when it was around 32-31% and now charging has again started from 0%.
What could be the issue?
I have tried the battery calibration app even though I know it does nothing.
Any ideas?

I have been flashing nightlies merrily on the Nexus4, never had to recalibrate the battery, though it sounds like your does need that. (I had a Desire HD before this, and it was very sensitive to errors in battery calibration)
How about if you charge the phone fully then either reflash the ROM or flash a nandroid backup you've made? Either of those options will overwrite the battery stats file - if that's the problem.
It could be that the chip in the battery is malfunctioning, ie a new battery could be needed, but that sounds much less likely

Okay I'll try reflashing the ROM when I'm at a 100%, I know deleting the batterystats.bin file doesn't do anything but I did that anyways yesterday, but it seems it didn't fix the calibration issue.
Any other ideas I could try while I charge my phone to a 100%?

Hi, @paul c, I would like to inform you that my phone's discharging just fine (charged it to a 100% last night and it's currently at 48%, I didn't reflash my ROM but I did reboot it once. I also haven't charged it since then)
Could you tell me what's the minimum and maximum battery voltage? I am guessing that the max voltage is around 4200mV but what's the minimum? Also, can we calculate the REAL battery %age from the voltage that is displayed by apps like DashClock? If we can do that could you tell me how/what formula we use to do that?
I know I'm asking a lot of questions and I would really appreciate any help here !
Thanks!

Hi,
I was inspecting the battery's voltage/charge the entire day today and I realized that at around 36% the voltage went around 3000mV (3100mV, Nexus 4's battery is rated at 3800mV and it maxes at around 4200mV). After that when I plugged it back in and turned it on it started charging from 0%.
I think the battery is at fault.
Is there any fix for this which does not involve replacing the battery?
Thanks!

Unfortunately this didn't work for me. I tried charging through the night and then discharging it completely and charging it completely again. I also tried deleting the batterystats file (even though I know it doesn't do anything)
So what do you suggest I should do? Get the phone replaced or get the battery changed?
I live in India and the phone is from Canada, so replacing the phone will take some time but I can get the battery replaced for around $20
Also my nexus is also showing +ve mA values while it's not charging, and the values are absolutely crazy, +268, +168, +1171 (in batter monitor widget)
Please tell me what I should do.

When you open the back case did you notice if the battery looks bigger/inflated? Maybe you should replace the battery.

Okay, I got my battery replaced, drained it to 0% (after a full charge) and going to charge it completely by the travel adapter that I purchased from the service center.
Attached are the pics of my old battery, I don't know if you can see it but it's swollen. If I recall I used a nexus s' charging cable to charge the phone from a computer and it was charging like AC (my kernel usb fast charge was OFF) and it also never detected my phone in the explorer (Windows)
My problem's solved now, it was a battery issue for me. I upgraded to PA 4.3 in the process by the way
So I guess I'll stick to my regular micro USB cable and charge via the travel adapter whenever possible, thank you everyone for your inputs!

Hello guys,
Please help me figure out how can i boot or at least make my battery charging LED turn on...
Scenario: I leave my phone downloading some files while charging at 5%. But then when i got back, my phone is already dead... Can't boot up, that's maybe my battery get drained... I have tried reviving my battery using a clip charger, tested it with a AC/DC Tester and it shows its already fully charged.. But then when i get back to my phone, it won't even start, can't go to the recovery, or even no light even if it's plugged.... Please help...
Thank you
Were you flashing anything at the time or just downloading some files?
If you were just downloading general files then no harm should have been caused if the battery just died.
I would advise that you just leave it charging in the wall for a small period of time and hope for the best, if that fails find somebody with the same phone and try your battery in their phone/their battery in your phone and see if it's a firmware issue or a battery corruption.
Let me know if anything else crops up.
