[Q] 1700mAh battery in green lens Defy? - Defy Q&A, Help & Troubleshooting

Is there any way to get a green lens (SOC) Defy to recognize the full capacity of a 1700 mAh (Mugen) battery? I'm running GGL (2.3.6) over the latest CEE Froyo sbf and the battery is recognized and charges fine but seems to drain as quickly as the standard 1500 mAh battery. There are various discussions of battery issues and fixes in this forum but I couldn't find an answer to this query.
Thanks for any suggestions.

Did it worked for you?
I think there could be a heating issue while charging..
I don't think that there would be problems with charging, I think that there will be problems with usage, 3.8V is a higher voltage than default battery's, so it could overvolt some hardware parts.
today igot the replacement battery , its HF5X battery for defy+, my phone is DEFY(MB525), phone is charging stops at 98%

Red Lens? if yes, you can flash a Defy+ Kernel and got a full battery...
If green lens, try to search some battery fix.
And sorry, i have a terrible english
I hope you can understand me :highfive:

Hi. How much did the battery cost you. I see HF5X on Ebay starting from 1500-1600. If the rate is same I'll order from them instead.

Defy+ Battery Compatibility

My Defy+ battery isn't charging anymore, even in other Defy, it only charges with an external wall charger, so I'm gonna buy another one.
In my country, the Defy (MB525) BF5X battery is a lot cheaper (less than the half price) than the Defy+ (MB526) HF5X battery.
The question is: The Defy (MB525) BF5X battery is fully compatible with Defy+? I can use it without any problems?
Note: I'm using the WIUI GB v2.9.27 (GB Kernel).
Thanks!
battery fix available here:
http://forum.xda-developers.com/showthread.php?t=1795647
note: bf5x and hf5x differs in battery chemistry and the top charge voltage slightly different (hf5x higher), so if you use hf5x on mb525 rom the battery won't full charge, but if reverse, theoretically can be dangerous(???), not 100% sure but overcharging lithium rechargeables is dangerous, tight voltage limit...

Hi there.
I hope is not too late - last post was in November.
I've tried a new BF5X battery with my DEFY+ (MB526) but it causes bootloops or shudden shutdown when it asks to enter the sim pin.
I've also tried with and old one from a used MB525 and it worked without any problem... What can I say...
I should advice you to buy the HF5X, even if it's more expensive, for sure compatibility.

Problem with high-capacity battery.

I bought a replacement battery for my defy because the stock battery has bulged and now quickly loses its charge. I got the new one from eBay and it has, 3500 mah. I'm currently using Mokee OS for my defy but the battery percentage that it is showing doesn't seem to be accurate because it has been at 1% for more than 12hrs now, no kidding. I have wiped the battery stats for this after the first full charge and I also used battery calibration. Has anybody experienced this when they replaced the battery?

You should flash your Phone with battery fix appropate to New one. try that one for defy+
That's what you'd get when using different capacity from stock ones.
Defy/Defy+ would recognize only 1500/1700 mAh batterys, it's fixed in the rom.
There's no fix for Hi-capa battery, you may just live with it, or try Momax 1500mAh if you like.
Try it with different battd binary files. According to this video it can work correctly.

[Q] HF5X on defy

Hey all,
I'm having a defy red Lens running cm 7.2 official. My battery's capacity has reduced a lot and I'm forced to take my charger to college as the battery would have only <10% left by the end of the day.
I'm planning to buy a hf5x battery , but i came to know that hf5x can be charged to a Max of 80% only without the defy+ battd. I have two questions
1: Can i use hf5x and bf5x simultaneously if i replace the battd & lib files to suit hf5x to charge full??
2: Should i buy a wall charger to use both batteries simultaneously??
Thanx

[Q] Change kernel voltage

I found a bigger battery for Defy MB525 which has(theoretically) capacity rated as 3500mAh(it is much thicker than original battery so there is a possibility it will last longer and that it isn't only a sticker with bigger capacity printed on it). However the problem is I own Defy+ MB526 which battery is 3.8V and the bigger battery voltage is only 3.7V. Is there a way to change Defy+ kernel to Defy so the battery will work properly or should I put it in without any changes and it will work fine as well.
