Battery only charges to 83% [fixed]

[kelbygreen]

Hey,

Charged my phone today and its only charged up to 83%. I seen some one had a link in there signature I read few days ago about fixing something like this but I cannot find it.

Does any one know a way to fix it??? I have battery monitor and battery calibrator but have not tried to calibrate it yet as the other day it charged to 100% so not sure why it hasnt today.

I am not sure if its the phone stopping it or if its the battery stats are out. it says its got 4167mV and the battery is a defy+ MB526 1650mAH.

Cheers

the defy+ battery goes up to 4320mV so u're battery does not charged. which rom are u using?

 

[kelbygreen]

I am using ICS 4.0.4

The rom is made for froyo kernels. The battery stat file in those roms are the ones for the normal Defy. Replace the Battd folder in /etc with the folder from a Defy+ ROM.

Explanation: Defy's have a 1700mAh battery, so do froyo kernel battery stats files. That's why you must "tell your phone" that your battery is 2200mAh

why after I installed it and the battery was at 75% did it recharge to 100% ???

But when I went to recharge the second time it only went to 83%? I am going to run my phone dead tomorrow (I know its not good for the bettery but they should have a fail safe in to save memory loss) and then charge it up full with not stopping and see what happens.

I cant figure out why it would charge to 100% once then the next time it wont.

 

[kelbygreen]

Well I replaced the battd.bin with a cm7 version and it charges to 100% but it stops at 4200mV I guess this is a failsafe so you dont over charge the battery???

I did not have battery monitor on any of the other versions I flashed so I am not sure if this is what it stops at or if it is still under what is capable.

You say the battery goes up to 4320mV? is that its max imput as it says its 1650mAH but has 1700mAH on the battery so I guess the 1700 is the max but it cuts off at 1650 as a failsafe?

 

[kelbygreen]

Ok maybe that didnt work as I had it off charge for 4 hrs and on the phone for 1 hour and its still at 100% and 4200mV lol Will have to try copy another one over. Sure I will find one that works.

 

[kelbygreen]

Ok got it sorted.

I found a CM7 battery fix for the defy plus and flashed that. It now charges to 4308mV so thats close enough for me and it shows when it was using battery. Was on 64% when I started charging as the other battd.bin files kept showing 100% and they where not draining.

 

[coas]

I have the exact same issue, MB526 with CM9 and doesn't charge beion 83/84 percent.

Do you have a link to the battery fix?

 

[kelbygreen]

I cant find where I got it from and the download link from the downloads does not work.

I have uploaded the one I used here so you can download that.

1.Put the zip into the root of your SD card.
2. reboot into recovery (cant remember if I used CM recovery or 2nd init.) Think it was CM recovery so hit reboot then hit reboot recovery.
3. Go into advanced and wipe battery stats
4. go back select apply update.zip from SD
5. flash the CM7 defy+ batt zip
6. once done go back and wipe the battery stats again (not sure if this was needed but I done it so keep to what I done)
7. select power off.
8. when power is off hook up battery charger
9. fully charge with the phone off (not sure if this is needed but this is what I done so maybe follow it)

If all went well when you put the charger in it should say the battery level leave it for a while hit the volume buttons should bring it back up if your curious if its charging!

It might have a green light at like 97% and say charged when you are in CM9 but leave it and it will keep charging upto 100% even though it says this.

Hope it works report back

Found the fix on a different thread, looks like the fix is working for me too, it's on 95% and charging.

It's on 4308mV with 95% and says charged. Before the fix it was on 4160mV with 84%.

I'll try your method and see what it will do.

Edit: it charged up to 100% and end up on 4313mV.

 

[kelbygreen]

yeah I got a cm7.2 one to work but it only got to 95% which is alot better but it was not perfect but this one got to 100%. From what I have been reading different things work for different people but if this works for a few then we might be able to put it into the defy+ thread but I guess there would need to be a few people to test it out.

Few people said the CM7.2 one just copying the battd.bin over works but it didnt for me. The epsylon one got to 95% and the quarx ones the battery had a ? when off and always said 100% 4200mV even though the battery was at 65-70%

Mine charges to 4311mV with the fix applied not 4320mV some one said it should be but its a heap better then what it was

 

[kelbygreen]

let me know of your finds coas as I would like to know what is working for other people so we can all help each other to make this work!

Sorry see your edit. So you experience the same as me?? it comes up charged with green light but 95% but it will still keep charging anyway and work its way up?

I am glad this has worked for you as I spent alot of time copying battd.bin files into my phone with no such luck. Please update here if this keeps working threw every charge as I have only done 1 charge so far. I may be able to write up a thread or tack it onto the all in one defy + thread if this is a proven way!

does this work for MIUI or just cyanogenmod?

I am not sure. you can try but I would copy your original battd.bin into your sd card so if it does not work you can copy it back over.

use root explorer. go to system/bin and copy the battd file. Go back into the sd card folder and paste it there.

then follow my instructions from the previous page and tell me how you go. It only flashes the battd file.

If it does not work you should be able to copy it back over push the mount/rw button in system/bin folder so you can paste the old file back.

You will then have to reboot into recovery and wipe the battery stats again.

Don't work

Stopped at 80% I complied a fix and need to sign it, can anyone sign it for me? It is from walter's kernel battery stats

 

[oSandmaNo]

I tried the cm7 battery fix on WIUI. Battery icon shows a question mark. So reverted to original battd.

You guys flashed on froyo based cm9 or gingerbread kernel cm9??

gingerbread CM9 kernel

Seems there is alot of conflict and no real true fix for this problem as quarx versions didnt work on mine I think maybe becoase I used epsylon CM9 but epsylon CM7 one worked but only charged to about 95%.

Its just a matter of finding the battd.bin file that works with yours it might take a few trial and error. copying them over from different versions.

 

[Maki-taro]

I compare using BeyondCompare some of those fixes over there( the one in this post and those on white rabbit rom)
and the thing is that is only 2 fixes,
Example:
FIX a ->WhiteRabit fix 1 == WhiteRabit fix 2
FIX b ->WhiteRabit fix 3 == WhiteRabit fix 4
FIX b ->and the cm7 fix in this post == WhiteRabit fix 3 == WhiteRabit fix 4

If someone have some other fixes post it so i can compare it to know if is a new posibility or not

gingerbread CM9 kernel

Gingerbread kenel? Then that fix of yours will work!! It doesn't work on froyo kernel . Battery will show a question mark if you apply that on froyo kernel
