[Q] 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?

i think you should go by default one..as it might be having issues afterwards like battery status problem on the status bar ,,,battery not charging etc..
also you can try defy+ battery i think its bigger then the default defy bigger in capacity not size.. size is same as of defy....
best of luck!

It is an extended battery,same size as old battery but has a 1700 mah.Price is $46.95 all inclusive i believe(shipping is included).Lots of good reviews heard about this one.Or you could just use defy + battery.Your call.

New battery... higher capacity than original???

hey all.
i am considering buying as new battery for my defy. the one i have is about a year and a bit old and batteries do tend to wear. i have come across a few on ebay that are higher capacity than original and am wondering if they will charge to full.

i have a defy red lense and am currently running cm7 kang by fuzz i think it is (great job mate by the way love it it is silky smooth). i am considering giving the cm9 rom a try out shortly so would also like it to work with that rom.
so will these charge up to their full capacity or will they not? if anyone knows before i take the plunge can they let me know please
thanks

I've got a 3500 capacity one it charges to 100% then runs down to 0% but then stays alive for an extra day I've got rid of battery icon just wish I can get rid of flashing red light and the warning on lockscreen. If your rooted you can get battery calabrator from market. It works but not for the massive batteries. Hope this helps
defy cm7

cheers mate exactly the answered i was looking for. will get one of those above then probably the 2400 one or whatever it is. that will do me i all i need is an extra 12 hours or so. i may even go and get one of the external batteries as well as a new internal battery as that would be good for all my usb devices. cheers again bud.

No worries glad I could help.
defy cm7

Does anyone think it is possible to create a custom battd.bin which supports the higher capacity? That would be really cool

Might be an idear!
I will have a think about it.

I would support that. I wonder what is required to change the battd file for larger batteries

Hi,
as I found, battery calibration doesn't solve this, even not on the smaller batteries. I use a 1700 mAh HF5X battery in Defy. Somehow it's recognized as 500 mAh, and not charged fully. I have the same issue: battery indicator stays on 1% for a long time.
I tried every fix and kernel I've found but nothing worked yet.

After checking, I think those batteries aren't so good (except perhaps the 3500 one) ... give a look at this thread : http://forum.xda-developers.com/showthread.php?t=1828768
More, I checked other seller on ebay and everytime the same, whatever the seller : all the bad comments are about "high capacity" batteries ...
Good luck to find a good one

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.

Also check negative feedback on eBay about capacity:
http://feedback.ebay.com/ws/eBayISA...=negative&interval=180&_trkparms=negative_180
- Volume of a real, 1400 +
- Fake! original ep500 1160 mAh working 6 h, this 2430mAh battery - 3h! WTF?
- 2430mAh are not correct;battery monitor gives 1435mAh;no differents with origina
Etcetera...
-------------
Bottom line: don't buy it.

thanks dude.... sorry for not searching the threrads before new post...
i m not gonna buy it..

I've got one and it seems to work better than the original battery. Haven't had any problems. Haven't been analysing though.

my friend bought one of these batteries for your defy and lasts only 3 hours
The only brand of extended battery really works is Andida , I had one in my old N78 lasted 1-2 hours more than the original

don't buy it
My cousin got this battery , apart from the inflated capacity , it battery also leaked fluid and became inflated :crying:

same size as bf5x/hf5x, significantly higher capacity, definitely a scam, may even be dangerous.
battery chemistry hasn't evolved that much in the past few years. there's a limit on the weight&volume/capacity ratio.
avoid it.

not that good
i bought it and it's 10% her half a hour :/

Third-party batteries often lack good protective circuits. They may die unexpectedly and/or kill your phone. Be wary!

There is also a possibility that those batteries don't get fully recognized by the defy and the batteries might not charge up to 100%

thanks for the warnings.
any idea where one could get a legit replacement battery?

[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.
