[Q] Battery problem

Hi guys!
I've bought Arc about month ago and I've noticed a problem with battery percentage, it has oscillations. For example, battery is on 25% and suddenly drops to 2 or 3% and for a while battery is on 18%, or battery is on 84%, suddenly drops to 74% and soon comes back on 85%. I've restarted the phone, repaired software but the problem is still here.
Battery life is very good, average life is 36-48 hours, but there is a problem with oscillation. Can anyone tell me what should I do?
Software version is 2.3.3.

Let me search that for you http://www.google.com/cse?q=Battery...sc.tab=0&gsc.q=Battery problem Arc&gsc.page=1

Hmmm... Why didn't I think of that?
My problem isn't 0% battery or short battery life. Read my post again and than answer me.

Best way to fix it is battery calibrate....but it needs root.
And when it drops and raise 2-3% its quite normal. My Neo doing thiskind drop raise trick when I make reboot and for me its not problem

Bootloader locked? Rooted?

Hi Sidious
It sounds like your battery are fluctuating more than normal, a drop of 20% is definitely not normal unless you are doing allot of booting and flashing at the same time.
One cause of the smaller oscillations could be that battery is not read as often when in deepsleep to save battery life. It might have some battery level estimations when you wake up the phone that are off by a few % when the next battery reading occur. Might also be temperature changes that also change the capacity slightly.

Arc isn't rooted.

I'm not sure what did you mean by saying that I'm doing allot of flashing and booting at the same time?

Battery sensing module automatically calibrates when it discharge from 100% to 2% or lower. So, let it discharge a few times to 2%, and try to do a light use (no games, etc) doing this, to help fuel gauge module to detect internal battery impedance and correct the % marking.

Hi Sidious
If you had the bootloader unlocked and was flashing new kernels or firmwares. I have noticed that the phone when in "fastboot" mode do not charge but consumes allot of battery, it usually shows as a sharp drop when the phone are booted up. "fastboot" can be used to flash new kernels on the phone, but I do not think this is the problem in your case when you are running the SE provided firmware only.

[Q] battery problem??

the problem with my battery is that when i use the phone it drains fast but it charges itself ex. i used it for 15mins from a battery percent of 41% to 31% (lost 10% in 15mins) then i leave it for awhile and it becomes 36%
i think a battery calibration might fix this...
has anyone tried a working battery calibration method? there seems to be alot of them on this site... all seems to have different ways to calibrate the battery... and most of them are over a year old
anyone know of a working one for the play??
i tried one before but it didn't seem to work...

I have this problem as well. When in standby mode I will gain 2-3%
My battery drains quite a lot as well. I think that might be normal.
Lets see what other users have to say.

This happens with a lot of batteries, since my old nokias, to notebook ones.
Depends on the temperature and how fast you are draining,this is more noticeable when I play Pro Evolution Soccer, Sonic EpI or NBA JAM on my Play.

Here's the battery calibration app I've been using for YEARS. It works awesome. Just wipe your battery stats, let your phone charge to 100%, click calibrate then let it die fully. After that charge it without unplugging it and you should be good to go. It does require root (obviously) but other then that it doesn't require anything special.

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.

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.

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?

Serious battery drain, don't know why?

For I guess about the past couple weeks my GS3 has been getting horrible battery life. I fully charge it, then unplug it and it's down to like 95% within like 10 minutes without any usage. I have the screen saver on so the screen is only at like 30% or so, but when I go to Settings then Battery it says that the screen is eating up 86% of my battery and I have no idea why! Any help would really be appreciated!!

I had a similar issue with the charger that came with my GS3, started using a kernel with fast charge for around a month then it just wouldn't charge at all, phone would light up and say it was charging but battery kept draining. I tried another USB cable and now it works like normal, fast charge and normal drain. I've done a bit of research on it and if the pins don't get a good contact then the voltage drops and I guess a low voltage charge doesn't last long at all.

The Battery Drastically Drained in seconds!

Hi guys. Im new here. I just wanna share about my Z1 compact latest battery problem kinda frustrated me lately.
I bought the phone 2-3 months ago, already with Android Lollipop 5.0.2. Since the purchase, I didnt really face a problem with the battery life as it lasted about 12 hours per charge due to my heavy usage of the phone.
But a few days lately, my phone being worrying me as the battery doesnt being as normal as always. For example, it can drain the battery drastically from 88% to 67% in a few seconds when the screen is off (in standby mode). Sometimes, in the middle of the usagefrom 39%, the phone suddenly shows the battery low warning with a 1% battery remaining, and without having enough time to reach the charger, it shuts down by itself.
In rare cases, I caught my phone drained the battery drastically when the screen is still on from 15% to 1% less in a minute.
The phone wasnt rooted and I didnt anything else besides my daily normal usage. The latest apps I downloaded before the problem occurred is Waze.
I tried everything to save the battery like using the Stamina Mode, force stops some apps, slides away all of the running apps in the background but failed. I even factory reset my phone and installed all the apps the way it used to be but still didnt solved the problem.
I still have about 8 monts of Sony warranty but I need you guys help first because I need to use my phone for work right now. Please help and reply.
Thank you. *Sorry if my English isnt that good*

When the battery jumps from 39% to 1%... Does it stay a long time at 39%? Or from 39 to 1 in few minutes?
Just curious...
Sounds like a warranty issue to me. You could try to find out what is causing heavy drain like with BetterBatteryStats. But no app ever should cause such drains.
Sound more like your battery is not okay.

The exactly same problem with me .I have 100% battery and indicator stays 100% for a half hour than drastically drains to 1% and shuts down.

Change your battery! I had the same Problem. I changed my battery with anotherone original from Sony, but a few weeks later the same Problem: quickly battery drain.
So I ordered me a battery from e-bay but NOT one from Sony! Now a few weeks later still NO Problems. Everything runs Ok now. NO battery drain at all.
