[Q] Battery drain...whoa

So i'm currently running CM7 on my incredible. I have been running it for a little over a month with no battery problems. Just recently the battery has been draining crazy fast. I'm saying losing 1% every minute. At first I thought it was my battery so I took the battery from my wife's Dinc to try her's as she has absolutely no battery problems at all. It drained the battery 8% in a matter of 5 minutes!!!
I left my phone on and had it charging all night and in the morning it was still at only 78% charged.
Is there a fix to this? Ideas?
Thanks for the help!

I'm surprised that it wouldn't fully charge over night! Seems like it only takes an hour or two to fully charge my phone (stock battery, cm7, incredikernel). I'd recommend a different kernel that has fast charge at least, might also help your battery life too. Chad's incredikernel or invisiblek are my favorites, both charge very quickly.

Charge your phone until it won't anymore while turned on. Then turn it off and keep charging until the light goes green. Then unplug it, and plug it back in until it goes green again. Then boot into recovery and go to Advanced -> Wipe Battery Stats. Reboot your phone and let the battery drain to 0% (don't plug it in at all until it's at 0%, it's relearning all the charge points and whatnot). Then plug it in and charge it all the way up again.
I hope this solves your problem!

What's your CPU utilization look like? If something is pegging your processor, the battery will run down pretty fast.

that's really weird. I got great BL on cm7. And I get comparable with a sense 2.1/3.0 rom which makes me very happy. I have a 1500mah battery, but I just got it recently and I got great BL with stock. But it's great because it came with 2 bats and a bat charger, so I just keep one on the charger and if I run low for whatever reason, I just swap the battery. And unlike a lot of battery chargers, when it gets full it doesn't start to drain, it keeps it at 100%.

I WAS getting great battery life. all of a sudden the phone had shut off one day and wouldn't go back on unless I took the battery out and put it back in. Since then the battery life has been just crap. I tried resetting the battery points and nothing happened. I think I'm just going to go back to 2.2. I never had any issues with cm7 up until now but something is completely ****ed and I can't do anything to repair it.
ugh.

Check what apps are consuming most of your CPU. If you nothing stands out there it may be worth buying System Panel ($3) for the monitoring capability. There are probably free apps that do the same thing, but I can only recommend what I've tried. Also, if you just recently flashed an over/underclocked kernel or just installed SetCPU, you may be running into Issue 9733, which has a known workaround. If you want any more detailed assistance, you'll have to post more details. Can you post an adb bugreport?

I'm not sure what happened but I decided to just flash a different ROM. I just flashed Kingdom Stock GingerSense 3.0. Works great! I installed all my programs on it just fine and I just tried installing the google apps zip (it has navigation, places, ect) and now I'm getting an error message. UGH! WHY! It didn't install the apps from the zip file and now for a few programs that I had already installed they are no longer there and when I try to install from the market place I get a "Missing Shared Library" error message. I'm trying to install the TD Bank app and Tweetdeck as well as Craigslist and get the errors. I'm not having any problems with anything else.

problem solved!

[Q] Desire turns off at 10%

Everytime my phone reaches 10%, the phone will shut down itself and it won't turn on again.
i have tried bump charging and calibrating the battery but still without success... anyone got any soulutions other then buying a new battery?
thanks.

Try this: fully charge the phone then let the battery drain completely, until the phone shuts down. Plug the phone into the wall charger, let it charge for a minute or so then turn the phone on while still plugged into the charger and let it charge completely. After a full (100%) charge, the battery indicator should be precise.
I've noticed that if i restart the phone of plug it in after charging, the battery indicator will show an extra 10%, so that's the main reason for the shutdown at or a little below 10%.
This operation should be repeated once a month, just to keep the battery and the battery stats fresh.
Don't wipe battery stats and don't try any other calibration tweaks. They might damage the battery. There are some people here complaining about that.
If the phone still shuts down at 10% after the above-indicated trick, then your battery might be old and in need of replacing, but i wouldn't replace it just because of a 10% indicator error if it can still hold a proper charge.

I have the same problem. I also calibrated my batterie and everything but it still turns off at ~10%.
But since I know that, it's not really a problem

Its always turned off at ~15% for me. I accepted that this was normal. I've seen a lot of posts around but no one seems to of found a proper solution. I actually doubt that there is a proper solution to this.
Punched in..

snq's kernel? I take it is normal with it as none of the GB sense rom managed to come even near the 1-2%. A bug with the kernel probably.
Flashed Oxygen last week - bam, phone turns off at 1%. No calibration was needed even .

Every time this happens to me I charge it 100% then I reset battery stats. Then let it discharge threw normal use then give it a proper charge, plugged into wall charger, not PC.....! And once its 100% ignore green light check it says 100% on the top bar then I unplug. Its normally always sorted then. But I have had to repeat twice in the past.
I also agree about kernal, often after updates it goes bonkers, and I'm on miui, lots of updates

Mine also used to turn off at ~14%. After using a battery calibrator, i could push it down to 7%. However, on the other "side" of the scale, it goes down qute quickly from 100% to ~92%. All this on GV2.8, and the unofficial ManU kernel 2.1.1.

Just wipe battery stats in recovery after full discharge if you changed ROM, and then let it charge to 100%.

Used the battery calibrator app (for nexus one) with detailed instructions. Now batt lifeis awesome, turns off at 3%.

[Q] Brand New Battery, Wipe Batt Stats?

Recently my battery went to crap on me and won't hold a charge for more than 8 minutes. It says 100% and when it hits 85% a few minutes later it shuts off. When I turn it back on it says 3% left. I've calibrated it about 20+ times, nothing works so I know it has to be the battery. Here's my question. When my new battery arrives (it's a larger one compared to stock), do I wipe the stats before putting it in? Or just take the stock battery out and put the new one in to charge? Thanks, anyone who reads!

If the battery ships fully charged, or you charge it externally before using it, then yes.
Otherwise, I'd put the battery in and charge it fully, then wipe battery stats & do a complete calibration.
Maybe someone with experience can help you out a little more. I have extra batteries but never wiped battery stats. But I charge them in an external charger so there's no need.

man i been having this strange problem too but i took my battery to sprint and they said its a good battery so im lost and this drop happens on any rom i flash or any kernal i have tried evrything from re-calibrate to htc fix where u let it charge then unplug and plug it back when u get your new battery let me know how it goes

That would be ideal if I could charge it before going in the phone. What if I just leave my phone shut off and put the battery in to just charge it?

Got you, bud. New batt comes in tomorrow, I'll see if it fixes the problem. I hope so, anyway.

I just put a new stock battery in and did the calibration as soon as it charged the first time.
Seems like it worked fine.

Okay for anyone that ever comes to this thread months down the road here is what happened in my case.
I went to Sprint, the gentleman asked what could he do for me and I asked him to test my battery. Before even taking it he said, "I'll test it but it's probably going to come up green." I asked why was what, and he replied, "Because unless something is really wrong with it, they all say green." So I asked him to try it out anyway. A couple seconds later he comes back and says, "Congratulations, you're the first person I've ever seen with a bad battery." I immediately did a, "YES!" Because if the battery wasn't the problem then I would have had to get a new phone.
So there you go, my battery was totally messed up, had to get a replacement.

[Q] Battery worn out?

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.
TVTV said:
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...

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)

Htc Desire Shuts down at 40-50% battery

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!

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?
