With new kernels and Android 4.3, is the Defy finally correctly recognizing bigger batteries with their real mAh? I want to buy a 3500mAh one, but need to know if it works upfront
It is theoretically able to recognise higher capacities thanks to a patch by quarx. But often such batteries are not as advertised.

Is this patch integrated in his CM10 (or CM10.2)?
Is it? If not, where do I find it?
It is integrated in all his 2ndboot ROMs.

I have a 3700mAh battery now, but it doesnt charge above 89%. I am on CM10 18/9.
Do I have to reset my battery stats?

No, try calibrating it. If it still doesn't work, then i guess your battery is not as advertised.
The battery is on 1% for over 2,5hours now. With active display. wtf 3560mV according to battery monitor widget.
/edit: 5hours 15minutes. display brightness 100%, stability test for the last 1,5 hours. The 1percent is holding position.

Hi folks, I'm running CM6 8/26 nightly with Snap v7.4 kernel with SetCPU set to conservative on 998mhz max and 245mhz min. I'm getting horrid battery life and I think I'm doing something wrong: I wiped battery stats in Clockwork and now my battery SUCKS. -.-
Question is, what its the proper way of calibrating an Evo battery? I've seen the official HTC response but I don't think it's going to make a difference. Isn't there another method that requires you to drain the battery? Any info will be appreciated I've been looking at forums all day.

You can't just wipe battery stats - there's a process to go through. What you're referring to is Cyanogen's battery recalibration method found here. Read through fully before wiping anything.
Thank u very much, I wiped the stats by mistake

Actually it is almost as simple as wiping battery stats. That command he gives is what the wipe battery stats command in the recoveries do.
1. Charge battery to full (where it's actually 100% not green light.
2. Boot into recovery wipe battery stats.
3. Fully boot into os then unplug charger.
4. Leave unplugged until the phone shuts itself off.
At that point you should be calibrated.
On a related topic, the Battery Graph app available in the market also has an option to wipe battery stats from within the OS, doesn't it? Might save having to reboot into recovery once you're charged up.
It's a lithium battery. You can't condition it. Just use it as normal and ignore all these placebo effect steps.

This is all about calibrating the software (battery stats).

They're not calibrating the battery. they're calibrating the phone to know when the battery is really fully charged which, until you do this, is not the case when the charge light turns green.
Regardless, none of this worked. I've quit all services, no sync, auto brightness and wifi and I'm still getting horrible battery life. SetCPU is set to conservative. It's BULL**** my display is on for thirty minutes and the battery dies 20%. I played a game on my friend's iPhone 4 for twenty minutes and his battery barely died 3%. This is really unacceptable and I'm probably going to return my Evo or sell it if the battery life doesn't get better soon from these methods I'm seeing online

Crazy man, maybe something happened cause that is pretty bad.
Have a backup to go back to, prior to this happening, to see if it reverts back to normal?
Naw nothing happened to my phone...... All of us Evo owners should be able to use this beautiful phone with all of the features at max without the battery going to ****. My phone has behaved this way since unboxing. I'm not a big fan of the iPhone 4 but I will give it props on battery life. I have yet to try the longer HTC method but it seems kind of pointless.....

If it has always been like that then you may have a bad battery, if it started after you wiped the battery data then it is just showing you bad readings.
You should be able to get a good calibration if you reset your battery data again, maybe try through your recovery if possible, and then fully charge it with your phone turned off. Once it is charged you can either use it normally till it dies or you can tether, use gps, watch youtube, etc, and drain the battery down. Just make sure you go from a full charge to the phone shutting itself off without plugging it in to anything. Do that charging with it off and using it till it dies two or three times and your battery stats will be calibrated.
When I did this to mine it showed my battery at 0% for at least half an hour before it finally died, and that was with me listening to pandora and browsing the web.
Edit: FYI, the Evo's talk time is usually between 6.5 to 7.5 hrs, the iPhone 4 is around 7 hours also. If your battery is not lasting that long you need to take it in to sprint and have them give you a new battery.

HTC's method worked wonders for me. i'm a heavy heavy HEAVY user (no, not fat) and I get a good 10 hours with everything besides 4g on plus surfing, gaming and tethering for SEVERAL hours. For all that I do on my EVO 10 hours is HUGE. If I have a moderate day of usage (maybe a little more than moderate for the average user) I get around 19 hours.
Btw none of this will help if you are getting near 100% awake time. If that's the case you need to find the software causing that first.

Try this, it helped me. I did not come up with this btw.
With phone on, charge until green.
Unplug and turn phone completely off.
Charge phone until green once again.
Unplugand turn on. Once phone had turned completely on turn the phone back off again.
Charge until green one more time then unplug and turn on and you're done!

Hello,
I have extended battery in my Atrix and I see it going from 100% to 50% in like 4 hours. Then I shutdown Atrix, boot it up and battery shows 88%. What can be causing it? Is it battery or OS?

Probably just compatibility issues. I do suggest running a battery calibration app or clearing battery stats in CWM.

Yes, you are right, just installed GB couple of days ago. So I don't need to do anything specific to make it work eventually right? I cleared Battery Stat in CWM.
I'm having a problem with my rom or kernel. The battery level stays at 100 for a long time, then all of a sudden drops to 50. Running on Mexdroidmod and demonspeed kernel v6. Any insight into this? thanks in advance
Have you tried battery calibration?

If after calibration, the battery is still acting abnormally- you should consider getting a new OEM bettery. It could have a lot of wear on it.
I have done the calibration. The battery holds a charge fine. The problem seems to be using the newer demonspeed kernel in mexdroidmod.
Now keep in mind to get accurate battery reading you need to recalibrate it few time with full charge and discharge at least twice. Now you can manually do it by resetting the batterystats.bin after its fully charged and then t charging it.
Keep in mind for LiIo battery you never fully discharge so you have to understand the mV and mAh capacity of it so you can safely discharge it which can be 0% but 16mAh with 3400mV+ since all battery is not same due to company and cell capacity.
If you flash new Rom and use it for 1-2weeks then fully charge it and then wipe the stats and then calibrate it. I have the most advanced battery monitor scale in real life so you can't compare it but for normal folks if done right you won't get the 100% long hang.

Hey,
I bought a 3500 mAh Battery on ebay for my Defy running on the last nighltly of CM10.
The problem that I don't manage to calibrate it correctly - meaning the battery charge displays drops at same speed than the factory battery till 1% left and from that moment on it stays on 1% for about 1 whole day before it switches off.
I tried several battery calibration tools, but nothing works...any ideas.
Cheers

Battery calibration just ensure that your battery gets charged completely.
Defy is intended to run on a 1500 mAh battery. A higher capacity will act just like yours and there' no way to fix it.
Hmmm shame:/
I was wondering..
Did you buy the
[Aftermarket Product] [2x Bundle Pack Package] Brand New 3500mAh 3500 mAh Extended Battery Backup Spare Extra Power Replace Replacement+Back Door Plate Panel Cover Faceplate Panel Fascia For Motorola Defy

on Amazon? Or at least the same product? (Can't post url cause I am a noob -_-)
Does the new back panel fit properly? Waterproof and all? I assume if it fits for the Defy, it would fit for the Defy+ too?
And I am thinking since most Defy custom ROMs are actually Defy+ custom Roms that come with a battery fix for the Defy (changing from 1850 mAh to 1500 mAh) it should somehow be possible to edit that battery fix and change it to 3500 mAh. I dont know how, though, but maybe if you look around in the battery fix file you'll find some numbers. Or some dev could help you.

Hmm,... there have been some battery fixes for 1500mAh accu on the defy+ kernel.
Maybe there is a possibility to build a battd and battd.so for a larger accu to get them correctly.
Are the battery fix - files just taken from stock MB525 and MB526 or have they been modded?
All the alternate back panels for batteries I found so far are not water proof, so better dont try it out...
Though Id be happy if you correct me there.

Check out battd files in Q&A (Defy battery drops explained is the thread title)
You can change them to match your battery capac.
i buy a similar battery to my milestone 2 the vendor talk to me see these steps to me works fine
when you buy
1 wipe battery stats
2 let full discharge and recharge by all the nigth whitout interruption 5 time for each process (to calibrate battery)
3 on last full diacharge install battery calibration app from market and let full charge all nigth long or 2 or 3 hours after the incator show 100% quicly remove cable and click on battery calib buttom of the app
i dont know if it is really necessary but.... to me works on milestone 1 and milestone 2

Hi,
I have motorola defy red lens and lately I have a problem with battery drain on all roms.
I am using Quarx's JB 4.1.2, and battery drain appears only when my data is on (100 to 0 in around 8 hours if I dont use the phone at all), if my data is off, it can last for days...
I am using BM tweaks, seeder and memfree. I think thats when it began. I also tried Flashing SBF and have the same thing on stock, but on MS2Ginger my battery lasts throughout the day (100 to 50 in 16h with data always on) if I don't use my phone but if I just send one sms or check email for 5 minutes, it spends around 5% of the battery.
I am now back to Quarx's CM10 (from Nov. 28th, Later ones apeared to have batt drain for me even before this problem) same thing without and with BM stuff, I even reduced overclock from 1200 to 1000, and all of my vsel values now i am using 300-16, 600-30, 800-42, 1000-52, and before it was 300-30, 600-42, 900-50, 1200-64 (or something like that....)
Original battery monitor says it is the display spending 50% of the battery, and my brightness is on auto, I even reduced default values for brightness cause I don't like my screen bright.
is my battery bad or what? (all battery apps say the battery is healthy)
P.S. I use quarx's kernel.
What is android system and android os. They aren't drains battery.

I have the same issue, I'm starting to think that my battery might be dying, it's been a year since I bought my phone, so I think its a logical thing to think that it's slowly fading away
I got a new battery, and it's all good now
Btw I got one for the defy plus, and it rocks, whole day, lots of usage, overclock to 1200 again, and still 60% left!!!
