My defy battery has been playing up every cycle now. Tried using battery calibration. Been trying both Quark and Eppy builds. Now on the latest Defy Quark build. Got a green lens defy. Haven't a clue what is wrong.
Nothing explains the massive drops. It always happens around these points every cycle.
Any solutions?
I'm having the same problem with my green lens Defy. When battery is between 40-30% it suddenly drops about a 10-15%.
I haven't been able to found a solution to the problem yet (I have yet to try battery fix, but i think only red lense Defy's need it).
At first i thought it was a battery calibration problem, but after wiping stats everything remained the same way as before (now I know that wiping those stats does absolutely nothing to the battery).
I hope it's a software related problem and not my battery dying.
I think it is ics-based. I experienced after calibration (Hard-battery-script) two drops every circle, 55-49% and 29/26-19%.
Cheers for the information guys. It's good to know I'm not alone. I couldn't find anything on it!
The only things I can relate is that it is on green lens defy's. Maybe...
Is there no solutions for you guys? I found that calibration did nothing too.
How long have you guys had the problem for?
I first found this bug after flashing CM7.2 RC1. After seen it twice, I decided to wipe battery stats but it didn't work.
After that, I flashed CM9 (epsylon build) and was behaving the same way as CM7.
I couldn't tell if this bug was happening on stock Froyo, since it didn't have any kind of battery graph and I wasn't noticing anything suspicious to install a more detailed battery app.
Easy,guys.
Although its battery has these two gaps,
it remains on power which means it lasts longer at every 1% than before when there's no gaps.
I have kept a record when I just purchased defy.
That time is 2.4 hours per 1%(full discharge) mobile(2G) standby,
and now I have these gaps (14% total)as you mentioned,but it lasts 2.8 hours per 1% at first 20% then 2.7-2.5 hours per 1% to the last.
Actually,it is the same amount and this is under 1 year use!
is it my phone or battery
im using cm9.
my original defy suddenly died (got swollen) so i bought 2 new battery from two diff. supplier. (SNn5885A). it charges ok for the first time but i noticed on the first battery when it got drained. it wont charge anymore. it got stuck on 4%. the other battery, not wanting to fully drained it, turned it off at around 50%. but when i tried to turn it on this morning, it got the same thing as the other battery.
the question is, is it my phone f* the battery or they are just no good? how will i know?
thanks

Recently my battery life has dropped extremely low. I have been running setcpu to underclock when not in use to preserve battery life and it was working very well draining 1% on standby every 2 hours approx. A couple days ago I had it on standby and somehow in the morning the battery was completely dead after I had fully charged it the night before. It is such a drastic drop and I didn't even change anything that I think it's the actual battery itself. I can watch the %'s drop just watching my phone now. Has anyone else had a problem with this? It seems that the battery can't hold a charge anymore.
Looking at my phone right now, I had it off the charger for about 10 minutes after it fully charged and it's already down to 90%.
The first question that comes to mind is have you made any changes lately? Installed new software? upgraded something? If your phone was getting okay battery life last week and now it's not, it's time to start pin pointing what, if anything, has changed. Keep it mind it is possible for a battery to die...
Someone on this forum told me to erase the battery stats. I was told to go into the recovery. I use clockwork. There is an option to reset battery stats. This worked for me but do some research on this site. I am not an expert but was told to do this by someone who is

Hello,
My desire, after:
an inability to restore nandroid backup
a possible corrupted sd card
a usb brick and inability to mount some nand partitions
and finally succeeding in fixing it, now using/running:
2.29.405.5 stock rooted rom
a new sd card (samsung 16GB class 6)
clockworkmod 2.5.0.7
s-off
seems that has battery issues. When it reaches below 30%, it drains a lot faster. In example few minutes ago, the battery was below 30% level and after sending a couple of sms messages the phone, without the "Connect the charger" indication shut down. Not even the battery icon was red.
What should I do?
After flashing the above ROM I ran an app called battery calibration (could this be the culprit?).
I haven't experienced such problems before the whole mess mentioned above.
Thank you for your time.
Well, it seems to me like a "classic" battery meter calibration issue.

In order to calibrate the battery meter - FYI the battery itself cannot be calibrated, as Li-Ion batteries have a very low memory compared to old Ni-Cd etc. batteries - you have to go through the following procedure:
1) charge the battery to 100%;
2) let the battery discharge until the phone shuts itself down;
3) plug the wall charger into the phone, boot the phone up then charge the battery to 100% without interruptions.
If the above procedure does not yield the expected results, you can try fully charging the phone (LED showing green) with it completely turned off (after completely draining it). Again, the charging procedure should not be interrupted.
Source: personal experience - had to do this twice after installing new ROMs, as the phone was shutting down at ~14% (working like a charm now).
Regarding the matter of battery wear because of complete discharges, Li-Ion batteries do indeed have a lower cycle count than old-school batteries, but the standard charge/discharge number a Li-Ion battery can take is ~350, so you can't damage the battery pack by doing a full cycle per month (required to keep the battery meter accurate).
Good luck!

Did this work you mate? I have the same issue with my year old batter now... the phone shuts down @ 40% without any warning... and when I charge it, it starts from 0% and as soon as it hits the 58% mark, it jumps to 100% by itself... and i cant seem to figure out what the hell could I do to fix it... I tried calibrating the battery using the awesome method described here http://forum.cyanogenmod.com/topic/11823-battery-calibration-thread 3 times and nothing changed...
bump bump.. i really need help on this guys... :/

Weird that after calibration you still get that kind of issues, does this only happen on your current ROM? I have the latest CM in my desire and everything works just fine... Maybe try another ROM if calibration doesn't work to see if it's a hardware or software issue
i actually had issues with MIUI first.. the phone randomly shut down by itself but when i turned it back on, it was perfect... then i switched back to Oxygen and while everything was fine, suddenly one day the phone died at 40% :S and from that day on the phone charges to 58% and then instantly jumps to 100%... and as soon as it gets to 40% it shuts down itself... i guess i need a new battery but i wanted to see wether i can fix this one somehow so i can use it till the new one arrives...

same problem
i have the same problem
my phone turns off at 20% battery
calibration does not help....
and battery is not bad - it works fine
i'm sure its the problem with calibration

phone turning off at 20% is fine mate because thats the battery guards against any damage
most of the phones ( smart phones) switch off at 20% as going lower can damage the System .
It shouldnt normally..It's supposed to work fine upto 5%
Have a look at this, it worked for me (but you need a compatible kernel, most AOSP are so)

Hey,
My desire shutsdown itself at 13%. The Desire HD of my brother shutdown at 0-2%.
Ive tried to reset batterystats but it doesnt help.
What can i do?
Gee, I can't tell.
How about googling about it first?
It was Same on stock rom as i bought it newly (before 1year), it cant be because its old, and Ive calibrated it too, more Tipps i cant find there,
It is a problem with the battery stats. HOWEVER. I've read somewhere (cant remember where ) that even though its an annoying problem. Re-setting the battery stats will not improve battery life. It will give you a more accurate representation but the battery life will stay the same.
Instead of messing around ressetting stats just remember that 13% = dead battery.
just my 2c
Some batteries shut down with 13%, some with 20%, some with 1% and others with something between. As long as you did not notice a strange battery drain, I would just stick with 13% = dead battery (as already mentioned).
Ok, i asked because i thought it isnt normal. Thank its ok.
Thank you
I guess it depends on the battery. I have one that goes almost until 0% and I have another one that holds only until about 11% or so... 13 is not that bad!
My desire did this, except it shut down at around 20%. I just bought a new battery, not even an official HTC one at this fixed it. Now it shuts down at 0-1%.
So basically, its just the battery imo. My battery was about 1 1/2 years old and had seen better days.
Used to have this problem
When I used CM7.0.3 I had this problem, now running LeeDrOiD HD 3.3.3 with Sense 3 and it only shuts down at 2% or less.
i have same problem too
same here
Mine used to do this aswell. Reboot to recovery and clear battery stats? Then full charge and full discharge.
Worked for me at least.
Mythbusters to the rescue.
Like every desire user am having this problem too. I often switch between roms. Even after resetting battery stats my desire dies at 15% battery.
http://forum.oxygen.im/viewtopic.php?id=723
calibrate the battery ****s down at 0% then
I think, you have to reset the Battery Stats. For me it helps!
Lol.
It is not a problem any longer since theGanymedes published his great guide.
Notice how he never mentioned wiping battery stats?

... buit how can i fully discharge the battery if it shuts down at 13 or 20%? even if i restart the phone, it shuts down again
Mine just shut down between 45% - 48%.
Ordered a new one
Same here @ 18%, going to test some methods and inform you
You need to recalibrate the registers in the battery. There is a special program that does that.
Use this howto and it will be fixed.
http://forum.oxygen.im/viewtopic.php?id=723
BTW, you need to have Cyanogenmod or Oxygen installed for this to work or a distro with a kernel that supports it.
I hv flash a .sense Rom on my WFS and i used battery calibration, everything seem to work fine, but i notice the battery percentage indicator is incorrect.
Case 1:
I charge the device till full and run battery calibration, after few hours without using the device, the battery shown is still 100%. after that i run some apps n games, the battery immediately shown 96%, after few minutes the battery drop to 88%.
Case 2:
Battery shows diff reading after a reboot, let say I now have 50%, after 1st reboot it show 45%, I feel that is getting weird, then I reboot again, the battery show 48%..
Anyone know what is going on n any solution for that?
Thanks..
You have a miscalibrated battery...Try wiping battery stats via CWM...if it doesn't work try removing the battery for 2-5 minutes...with 4 minutes for me being the sweet spot...the latter solution works for me...try and test...
Battery stats doesn't actually do anything people.

Yeh all I've read about battery calibration in the past few months since I got my WFS unlocked and started playing around is that Battery Calibration is a pointless task that does nothing.
Anyone else find it amusing that some ROMs still include it as part of the initial setup?
Hey guys,
Assuming you have read the title there is something weird about my phone.
It shuts down at 40-50% battery (before it shutsdown it says empty battery briefly and then the htc flash screen appears and shutsdown).
The weird thing is the following:
It shuts down at let's say 40% battery, but when it re boots the battery is litterly empty (even when i boot in recovery it says --%, and when i plug the charger it starts at 0% again).
I have tried:
Battery Calibrator
Empty full fill up with wall charger and also tried usb charger.
Screaming @ phone
wiping battery data in recovery (4ext recovery)
The thing i am most confused about is that it goes out at 40% and when i turn it on again it's 0%. This never happened as it happened for the first time 2 weeks ago, confused. I tried different roms and it still happens (even ICS roms).
I wouldn't really mind if my phone would shut down at say 20% when it says actually it's @ 20. But as i said before: It says it's 40 (batterij indicator htc sense half full) and then shutsdown realizing after reboot it's completely empty.
Any help is much appreciated!
Mendel
Shutting down on let's say 15-20% is quite normal, but I never heard of one shutting down at 40%
Are you using the stock battery, that came with your device?
Sent from my HTC Desire using XDA
Any chance to try another battery? Seems really strange cause in most cases if you wipe battery stats you get your phone shutdown at 20%, not 50%.
Its most likely a bad battery that needs to be replaced specially if tue same thing happens when using a different rom.
via xda app
Yeah i know it seems so weird that's why i started this thread.
Before i buy a new battery:
What could be the cause that the phone goes out at 40% (or 30) and when it reboots it's empty.
Seems like the phone or the battery aren't in "sync" until it reboots to show it's empty.
Any tips or suggestions?
Thanks!

I'd like to think of it similar to laptop batteries that have gone bad... you plug your laptop to it's power supply, it says fully charged but as soon as you pull it out from it's power supply it drops to 50% in minutes and then goes off. The battery cannot hold the charge anymore.
It can only mean that the battery's life is at an end. The only thing you can do is to change it. I suggest that you stick to original HTC battery as the "ChinaMade" ones will die a lot faster and you'll have to change it sooner than this one.
Regards.

Hey guys!
I know this thread is started since several months but I actually have the same problem : I have a HTC Desire and its shuts down at about 50% and when I reboot it, it says the battery is empty.
I tried several times to recalibrate the battery (and to do all the things MendelMusic said in his post actually) but nothing changed.
MendelMusic, did you finally manage to solve your problem?
Anybody have a solution or any ideas?
Thanks!

Battery drain?
It's called battery drain. I have it too, but only at 10/20%?
If someone knows a fix, please send it to me
AW: Htc Desire Shuts down at 40-50% battery
Probably your batteries are just weak now. I'd recommend you all to invest 5 bucks in a new battery. Actually that helped at my old desire. Greetings
Thanks for your answers!
I tried the link of madreef and it didn't change. I will try again, maybe I did it wrong (hope it will work this time...)
@dschibril : I don't think my battery is weak because the problem occured as soon as I changed the ROM (CM10). The battery was perfectly ok before that.

Hello, I have the same problem with you. Did you manage to fix it and how? Have you tried a brand new battery so far?
It has to do with the Desire's poor battery age management system. Li-Ion batteries age, meaning that, as time passes, they're gonna be able to hold less and less milliamps. After almost two years, my Desire's battery can only hold 82% of the original ~1400 mA charge.
The only way around this is to use the Nexus One Battery Calibrator (Nexus One and our Desire share the same hardware underneath the hood). You'll need a compatible kernel and some patience. Instructions in this post.
My 2 cents: if your battery is only able to hold less than say 75%-80% of its original charge, then you should replace it. Li-Ion batteries age in such a way that they suddenly go dead, so it's not worth taking the risk.
Later Edit - If your Desire shuts down at say 40% - 50%, that means that your battery is 40% or 50% gone, so it's time for a replacement. I'd still try the battery calibration method i wrote about in the above post, just to determine if it's a freak software error or the battery's fault.
P.S. - Wiping battery stats does nothing to solve most issues (for the Desire, at least).
My phone turns off sometimes at 50%, sometimes at 80% of battery.
I have new battery now (original one) and it is the same. Phone turns off, only when it is connected to charger it does not.
Hiii
My hTC Desire 728 shut down when then battery showing 50% to 60% in charge. What is the remedies?
