Battery Replacement for Defy

My Defy Battery's almost out. I'm thinking about buying another. The battery is BF5X; However some guys said that Defy can use Atrix 4G battery: BH6X or Milestone 3: BF6X - I don't remember, anyone can confirm that? What about the size? Won't they fit Defy?
I've already tried Defy+'s HF5X but I still need a higher capacity battery

Not a chance!

nope!!

Nope!! , and even if they did ,
you will have issues with the rom not recognizing the new batt

New battery question

Hi, I need a new battery as mine is worn, I need to know if I buy a higher capacity battery (ie mugen or defy + battery, not fakes) on my green lense defy will it cause me issues? If I flash a defy + rom I lose camera as I am green, so can I safely use a higher capacity battery and still get a full charge out of it?

It should work if you flash battery fix in froyo kernel ROMs

If the mugen is for MB525 then you need no fix.
For the Defy+ battery, I think you need to flash the battery fix that was going around in the Epsy CM threat (as he has no Defy+, he used the Defy batt and the Defy+ users had to flash a fix.)

Yes, so even though its a bigger capacity it will read right?

I won't vow but I thought the Defy+ battery works with the battery fix from here:
http://forum.xda-developers.com/showthread.php?t=1795647
There were some that tried. It somewhere in the Q&A
The mugen 1700mah will work. It is a 3.7 lithium ion battery. Same as the MB525 (BF5X) one.
The one from the MB526 (HF5X) is a 3.8 lithium ion polymer battery.
The 'replacement' battery's from ebay with stated to work with Defy+ are all for Defy so a nogo for the Defy+ users.

I have just bought a Defy+ battery for my Defy (green lens). The problem is that you never know how much battery is left. It goes from 100% to 1% in a few hours and stays in that 1% until it is fully drained (10 hours or more).
For what I have read it is impossible to have green lens camera and the Defy+ battery working at the same time:
- If you use froyo kernel camera will work but the battery won't.
- If you use gingerbread kernel it will be the other way round.
So for now I prefer a working camera without knowing how much battery is left.
The only silver lining I have found is in this thread (http://forum.xda-developers.com/showthread.php?t=1627631). It is for the photon 4g but it might be possible to make it work in our Defy.

Weren't there defy+ users on froyo kernel? (By flashing the bl5 eclair or BL6 froyo)
Are you sure you have the right battd and lib?
But I don't know for sure of course because I don't own a defy+ nor battery.

I don't see why a Defy+ user would have a Froyo kernel, neither the camera nor the battery will work.
I have tried another battd/libbattd but it gives a question mark inside the battery meter.

Sucks.
Camera does work AFAIK.
They did it when CM9 began and epsy did a couple of defy only roms and some defy+ users couldn't wait.
And they can return to GB kernel just by flashing it in recovery.
Could be the battery doesn't work on froyo kernel. Sucks a bit for Green lens defy users.

There is no real fix for battery on red lens defy+. It might show you full charge but it will never go more than 4.15V and it used to be 4.35V in stock rom.

[Q] Swap Battery BF5X/HF5X

Hi Everyone,
I actually live in China and I bricked my old French Motorola Defy (MB525, bought with Orange operator). I think I can fix it because I still can access the bootloader and I just have the "Low Battery" error and can't do anything.
So I bought the Chinese version of Defy+, called Motorola XT535 (XT536 in my case but still the same), it's not exactly the same hardware than Defy+ (eg. I have a front camera). But I have the same battery than Defy+.
Here is my old battery :
BF5X
3.7V
1500/1540 mAh
5.6/5.7 Wh
And here is my new one :
HF5X
3.8V
1650 mAh
6.3/6.5 Wh
My question is : Can I charge my old BF5X battery with my new phone ?
Thank you by advance for your answers ! (And sorry for bad English

yes u can use HF5X in defy MB535, but with stock Rom , its charged upto ~80%,
i am using CM10 and using HF5X battery in DEFY MB525(not defy+), its works fine for me

Thank you for reply ! But my question were for the opposite, I meant BF5X into Defy+ (or better XT535).
Thank you again

You can use battery from Defy+, but to use his full capacity you have to install the apropriate ROM.

Not problems at all and charges to full 100% but Battery Monitor shows 1500mAh when the battery is 1700mAh.
I dont know what I can do for detect the right capacity.

[Q] Defy Battery Problem

I flashed my defy for the 100 time and this time my battery got stuck at 100%. I discharged it, and when charging it shows a '?' where % should be.
It always show at 100% at the notification bar.
Do i have to wipe anything, flash anything? I really have no idea.
I'm running quarx CM10 4.1.2 2ndboot, and i own a defy green lens. Also, i flashed touchwizz add-on, if that matters...
thanks

So, i've got news. the phone will only boot if connected to the charger. If i remove the charger, it dies. I still could access the recovery and wipe everything and flash clean 4.1.2 from quarx (2nd boot, cm10)
Im kinda freaking out now.

yeah?

I have the battery icon appearing with a question mark from time to time.
Would the red lens battery fix this? I have a mb525 green lens that a friend flashed with a build for the defy+.

+1
Me too

I wish I could provide an accurate answer to how I fixed it.
Since I used my Moto Bravo to charge the battery and then continued flashing sbf and then cm10, I don't particularly know what fixed it.
Good luck :/

Difference between Bootmenu and OS battery percentages

Hi!
My device shows a different battery percentage when I'm in the bootmenu or booted up into the OS. For instance when the OS warns me to charge the batt., because it's on 1%, the Bootmenu shows <30%.
I TRIED WIPING BATTERY STATS, BUT NOTHING.
Please help, because it's so annoying!!!

Somebody?....................Anybody?...................

According to my knowledge Recovery uses battery voltage to calculate percentage.
Sent from my MB525 using Tapatalk 2

OS display what batt stat give to it with a modified to 1% precision.

So what should I do with it?

Well, if it's happen because of difference voltage messuring method between OS-bootmenu, then I don't think there're any fix.
And why bother? You won't stay in bootmenu so long, right?
You should just ignore bootmenu's batt and care if your OS batt is correctly configured.

I just can't ignore it, because it drops the battery so quick and when it drains to 1% it stays there in full load for about an hour. I tried to calibrate it and wipe battery stats, even changing battd file from MB525 to MB526 but it's still the same as at the beginning

What battery you're using, 1500 or 1700mAh?

I'm using an aftermarket 1500mAh battery.

Ok, then you should revert your battd back to MB525.
What's rom you're using? If anything I'd try a stable rom like MS2ginger (with the right patch for the lens and no touching defy+ batt patch).
To see if this happens over roms.

I'm using Quarx's CM10. Can you send me a proper link for green lens defy???

While using CM10, have you already fix your battd with this?
http://forum.xda-developers.com/attachment.php?attachmentid=1241322&d=1344093287
It's from CM10 FAQs http://forum.xda-developers.com/showthread.php?t=1795647 "New Battery Fix" to fix for defy 1500mAh battery
(since CM10 default battd files are for Defy+, if I'm not mistaken.)
I used this for my Defy with Momax 1500mAh and no problem with batt % while in OS.

It seems to be successful. I flashed the .zip and my battery on the diagram jumped from 20% to 60% I did it about 2 hours ago and I have no battery drops, so I think it solved my problem
THANK YOU SO MUCH!!! I REALLY APPRECHIATE YOUR HELP!!!
