[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.

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...

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?

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.

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!

Mine used to shut off around 32%. This forum fixed this issue:

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?

[Q] ~4 hours battery life on standby after factory reset and new battery

Hi Guys,
Recently my USB charging port stopped working. I tried to clean the area and move the pin back up but nothing worked. I ordered 2 spare battery's and an external battery charger. At that point, I was getting 2-3 hours of battery life. Once I did a factory reset on my phone, I began to receive 4-5 hours of battery life, which was okay since I have 3 batteries. I've also ordered the part to fix the USB port.
My guess is that fixing the USB port won't solve the battery usage problem right? I've noticed that if I turn off my phone at 20% battery and turn it back in the morning, the phone is dead, as in battery is being used even when the phone is turned off, which is weird.
Is there any fix to this issue? What would be causing such battery depletion?
Thanks for the help!

how long has this been happening? new issue or recent.
try DLing disable service from play store. allows you to go into each app and turn things off thats running in background.
also, wakelock detector, lets you know whats draining your bat

If device is discharging quickly even when turned off, factory resets, kernels or other software tricks probably can't help. Replacing USB port however sounds useful. It may be damaged in a way that drains battery.

its been going on for a month now. The battery life has slowly gone down over the past few months but I don't exactly know when it became so drastic. What's bothering me though is that when I did a full factory reset and nothing was running on my phone, not even google apps only wifi and regular cellular data, I got ~4.5 hours. How does that happen on a new battery? That must be a hardware issue right?

Ah okay, so even if I'm not using the USB port currently, it could be linked to the battery drainage problem?

LG G3 Battery problem

Hi, I have a problem with my g3
The battery dies so fast and i dont know if its battery problem or maybe system, I have fulmics 7.0
Second problem with battery is that when it says 30% it sometimes switch off, and when i try to wake phone up it says 0%
What should i do?

It's battery. I have 2, one die after 5 hrs on 20% another keep about 12 hrs on same mobile. Buy new one.

Calibration will help , try thisBattery Calibration apk

LG G3 discharging very quickly (crDroid)

So one morning I woke up and found my phone hadn't charged and then when I started using it the battery went from 60% to 0 in about 30 minutes.
I have crDroid for lg g3 on it with it's latest update (when posted).
I've replaced the battery and changed chargers and it hasn't changed anything.
When in use it's temperature is about normal (35 degrees CPU temp).
After charging the battery outside of the phone I tested the idle time and it's almost as bad as when it's in use.
I dunno if I've accidentally killed some internal system or what but any suggestions would be appreciated.
