[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.

Battery life number jump problem

Anyone have this problem?
My battery is below 15% there is a pop up. After few mins..about 1 or 2mins when it reaches 13% it jump to 1% and have the 1% pop up and then shut down.
Anyone have this problem?
Isit something to do with the values in system?
By rooting or flashing new ROM does it fixed the problem?
I on ics...not rooted

You could try getting root, and wiping battery stats in CWM.

Never did I encounter that kind of problem. Anyway, my ION is just 9 days old as of now and I know that batteries has to go through a series of charge and discharge cycles before you can get its optimum performance.
What I did was insanely used my ION until its get to 5% of battery power left then charged it, I did that for a week. What I did on the eight day was quite different. When the battery reached 5% of its remaining power, I turned the unit OFF. Plugged in the wall charger then turned the unit ON. In this case, the operating system won't boot up. You'll just see an animated battery that tells you that it’s charging and left my ION on that state for 12 straight hours. Aside from that installed this little app and configured it.

Now, after eight hours of moderate usage I still got 80% of battery power remaining. Though Wi-fi is only turned on during manual sync. Bluetooth turned off since I despise bluetooth devices. NFC turned on only when needed. Brightness is always at the lowest level and only maxed out if needed.
You may not get the same results but I hope this helps.

battery weird fail/very fast discharge

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.

XPERIA Ion battery drain issues

Hey,
there is a big problem with my Ion's battery the percentage drops by 1% nearly every 25 seconds of on screen time (no Wi-Fi, blutooth or network just look at the screen) i've been using a KitKat ROM for quiet a while now with no problem, but suddenly and out of the blue this happened to my battery, i flashed another KitKat ROM and a JellyBean ROM with the same problem.
Yeah, everytime i reboot the phone the percentage drops by nearly 10%
I searched the forums for similar problems everyone was complaining about 7-8 hours of battery life, but mine barely makes it 2.5 hours even idle.
Thanks in advance.

Charge your battery %100
Let it turn off after it hit 0%
Charge to %100
Let it turn off when it hits 0%
Keep doing this because this a few times
This alows the battery to calibrate and fix this issue
Its fixed for all devices ive faced this issue with

Battery issue.

Hello everyone.
Past couple of weeks I have been having issues with my phone battery. No matter how much battery I have left when ever I play some game or edit photos my phone will all of sudden drop from 70%(or any given point) to 0% and switch off. At first I thought my battery was not calibrated so I drain to 0 and charge to 100 while it is off for couple of times but problem still occurs. Also when this happen my phone charge only upto 80% and stop charging until I unplug and plug back in order for it to charge100%.
Is there a way to fix it and how could I check if my battery is bad?

First, battery calibration is basically a placebo. It does nothing nowadays.
The whole thing about waiting a few days after installing a new rom or firmware so that the battery can "settle down" is real though, but is only because the new firmware will be doing a lot of background stuff and thus drain the battery more than usual.
Second, the only way to tell if your battery is bad is to try a new one. Unfortunately.
Based on your symptoms though, your battery is DEFINITELY bad. I'd recommend either sending the battery out for warranty, or buying a new one. Or both- you'll end up with 2 new batteries that you can swap out if you're a heavy user.
FYI Warning- apps that claim to scan and repair your battery are scams. There is no way to scan your battery. It isn't a harddrive.
Just thought I should warn you before you get desperate.

Been having similar issues with mine as well. My phone will show about 20% or more left in it, but then the phone ships down as if it was completely drained. When I plug it in, it will show the battery is dead. Also, like a little whole ago, it showed 25% left, but when I plugged it in, it went to 12%. It also continued to drop even while plugged in and showing it was charging. I did a battery pull, cleared the cache, then rebooted. It showed 18%, but only 23 minutes left to full charge. I did another battery pull, and it now shows 1 hour and 43 minutes left to full charge.
Like you, this has been going on for a few weeks now off & on.

I had problems a little while back (not as bad as these). Mine would die with the percent showing around 5-8% remaining. I took the battery out, held the power button for about 30 seconds, then continued normal use. I read somewhere that doing this somehow helps. I don't know if it's true or not, but now my phone doesn't die until it hits 0%, so something did change.
