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

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.

BTW, you need to have Cyanogenmod or Oxygen installed for this to work or a distro with a kernel that supports it.
Whenver i flash a new rom, i make it a point to use BatteryCaliberation from Market.
Though since the last couple of times, I have noticed a weird thing.
Whenever i let the battery charge, it stays on a particular % for too long,
in my case (most of the times), its 60% or 72%. And then directly jumps to 100%. (this 100% is confirmed by the mV in BatteryCaliberation.
And while discharging, it goes to 0%. Then when i remove the battery and power on, it shows 2% (Although one time , it went to 20% )
Is my battery broken and should i replace it? (It has been giving me crappy battery life too)
i've got this, always charges up to 70-80% and stays there for a while, then jumps to 100%, changing roms, calibrating battery doesn't fix it.
Always wondered why it happened, I assume it's to do with the battery but not sure if faulty or not, hopefully someone can shed a bit of light...
First guys The battery calibration has been shown to be pointless and useless. Dont bother doing it. Next if you ever do bring a battery to pure 0% then it will bot boot at all. The issue could be many things. From a bad battery to just the way your device charges. As long as it last a decent amount of time then you may be able to rule out the battery being bad. I wouldnt worry about it unless you see the battery discharging really really fast.
Try to go into recovery and wipe battery stats, and then discharge it to 0 % until it won't turn on and fully charge it 0 ma on current widget. it happened to me many times and this is how i fixed it (old problem on hd2 on android nand)
Hey all,
I have the wildfire running with a stable CM nightly (forgot exact version, but already a good year old I think and never any problem with the battery). I have not recently done anything special with my phone (no new radio, ROM, updates, new apps, ...) but since a week or two I have the following problem:
Charging the phone takes first of all ages to reach 100%. And when it's charged, it will crash about 4 hours later. The battery indicator will be at about 35% or higher just before it crashes (thus not at 0). When I reboot (while charging after the crash) however, it says 0 or 1% left. When I then go to the settings -> about phone -> battery , the battery life just INSTANTLY drops from about 60% to zero (see picture)
This problem appeared pretty out of nowhere. Is this a battery calibration problem, or do you guys think the battery is just at the end of its life? I'm aware that this could just be it since the phone is almost 3 years old (bought on day of release here), but it's just acting so strange.
Any help is appreciated,
Thanks,
Maarten
Try the two obvious things
1- wipe dalvik cache and cache partition
2-wipe battery stats
Can you post a screenshot os the battery usage screen
The level indicator is in the first post, the usage (apps etc) I cannot do right now as after wiping it does not reboot anymore (stuck at HTC screen), but it was about 50% for signal and 50% for standby (or what are the 2 largest users in %, I forgot)
Wipe battery stats or manually delete batterystats.bin. Calibrate it. If nothing works reflash your rom. Not a battery prob.
Odp: battery weird fail/very fast discharge
I had similar situation. Change battery. It is broken probably.

There seems to be many battery problems for wildfire, I had to abandon mine because of a similar problem, except it would charge to 100% but then drop to 4% within a few hours and wiping battery cache never helped, tried my battery in another wildfire no problems so in the end I gave up with it
But I remember someone saying it was something damaged inside the phone
Anyway good look with your issue hope it gets solved.

I fixed my booting problem by reflashing the ROM. I also wiped cache/dalvik and battery stats.
The problem remains however. Stays around 100 pretty long, then goes to 80% in less than an hour. And then it crashed around something like 60%. After rebooting it said 34% left.
Guess the only thing else I can try is to completely empty the battery, then recharge it whilst the phone is off.
I'm going to buy a new smartphone soon, so it better just work another month !

Yea, wipe battery stats again, sue ur phone till its 0% and charge up to 100%, keep on charging for about 20 mins.. try then if battery shoes properly..
Doesn't seem to solve it... Completely emptied the battery (or at least I'd think it is empty, see further), then charged for like 8 hours whilst phone is off, then wiped battery stats in recovery. Then after rebooting first thing it did was crashing again.
The crashes often seem to be related with internet/apps. I now have internet and poweramp app off and it works fine (no crashes), but when I turn these on, sometimes after a minute it crashes, pretty weird
Also after some crashes, about 15 minutes later I can suddenly reboot, then it showed 15%, then it crashed again. After reboot (without any charging) it showed 65%... The indicator is completely ****ed up it seems...
Guess there is nothing to do but getting a new phone as this is too annoying. Thanks for the help though !
Batt voltage meter defect
I have a exacly same problem.
It is the voltage meter problem. Mine wildy shows 4.07V at fully charged battery which if you measure conected battery on its terminals mulitimiter shows 4.273 so its off by 0.2V. Now the phone will never light green led, it think battery is not charged fully. I checek this with 4 years old and new original htc batts. Same thing, voltage meter defect! If you charge it to full, multimeter shows 4.237V on batt terminals,reboot it and get a spike to 92% it suddenly drops to 78% even though mains charger is still connected and charging! Internal Volt meter also reads dorp from 4.07 to 4.02! :crying:
There i also thread on Desire Z forums of same thing happening here.
Is this HTC using crappy mobo components?

Htc wildfire is no more released now. It stopped in 2010. This has the answer. That is one of the bug with wildfire.

My htc desire HD gets unusually warm at the bottom close the sim compartment and drains my battery thats 100% charged in just an hour and few minutes. Even in airplane mode.
Whats worse is even when the phone is put off it still gets warn and my battery drains, I have tried everything possible to fix the problem from buying a new battery to installing battery saving apps and even flashing roms and even stock roms but Nothing works.
When i check whats using up the battery, it shows that the screen uses about 76% of the battery even when my backlight is deemed to the lowest.
Pleaze has anyone had this sort of pblm before? could it be a hardware pblm since the phone still gets hot when the phone is put off and the battery still gets drained.
Wipe Battery Stats
Try wipe battery stats in ClockworkMod.
