[Q] CM7 battery charging % stuck - HTC Aria General

Hi guys,
I'd gladly post this on the CM7 RC's thread over at the dev forum but I have yet to accumulate 10 posts.
Lately I've been experiencing weird battery % issues in CM7RC2 and now CM7RC4, that the charging would be stuck at a certain percentage even if I charged it overnight. It never goes to full, until I pulled the battery and rebooted.
Is something wrong with my battery?
Thanks in advanced!

Are you using an official battery or a third-party battery?

I'm using the official one

I'd try charging the battery to full then wiping battery stats from within Clockwork Recovery.

I would definitely try this.. I had the same problem and it worked for me.. after you reset the stats, drain the battery again till the phone dies, fully charge again, and wipe again

First, doing the battery drain is effective in calibrating the battery meter but is still probably a bad idea because by doing it you are decreasing how much charge the battery can hold (i.e., a full charge will not last as long). It might not be super noticeable, and doing it once in a blue moon is likely not a big deal, but don't do it often or you'll just end up having to replace your battery. Deleting battery stats should be enough to correct the OP's problem, and allowing your phone to recalibrate under normal use is fine but takes longer.
That said, I do the battery drain anyway, but I would definitely suggest not doing it more than once every 6+ months. Wiping battery stats often is not necessary at all, unless of course you are actually having a problem like the OP is.
Second, you definitely should not clear battery stats AFTER performing a battery drain and recharge. The whole point of doing the battery drain is to let the phone gather new information about the battery since you just wiped the battery stats. If you wipe them again after doing that, the battery drain was useless.

Wipe battery stats made it worse

I followed directions on what I thought to be a battery fix, but it ended up making my battery life twice as bad. Actually it takes longer to charge now than it does to drain.
Anyone else have this happen?

I did the same thing, but I've only charged once and I didn't time it. I haven't been timing any of my charges or discharges, but maybe give it some more time, that's kind of how stats work isn't it....usage over time? Good luck.
Today I started at 100% (not a powered off full charge though). After 2 hours of moderate use I was down to 50%. I have been charging for an hour via car charger and currently at 67%.

Not to be a dink, but then it would appear that you didn't follow the instructions. As a result, YMMV I guess.
1. You will need to charge the phone to 100% (while the phone is off).
2. Leave charging cable plugged in.
3. Boot into recovery and wipe the battery stats (should be under Advanced).
4. Then boot into Android.
5. Then remove the charging cable.

Give it another shot, and I would suggest that maybe it not be thought of as a "fix". Try using the wall charger as well. I only use the wall charger as I have a converter in my vehicles. Let us know how it goes!

Those are actually the directions that I followed yesterday afternoon. I didn't notice the battery life being any different after doing that initially. At the end of the day I charged my phone via wall charger for roughly 8 hours while I slept.
I was unplugged for less than two hours and watched it drop down 50%. Wifi was off, Gps also off. I was doing some web browsing and also using the xda app. I played a game for a couple of minutes.. That was it. I really should've checked the battery usage but I didn't think of it in time.
I only charged it in the car today out of necessity because of the super quick discharge. When I'm at home I only charge with the wall charger.

I'd venture a guess that you have something else running the background. I honestly wish that I had something more for you, but I'm going to have to fold.

I've heard others say they found facebook or twitter running in the background and that when they killed that it made a big difference in battery life. Perhaps that?
WiFi set to never turn off
I noticed this morning that WiFi had been set to never sleep, I just changed that t 15 min.
Had a full 100% charge last night did not leave on the charger, minimal use this morning down to 78%.
Let's see how the new WiFi settings works.

that doesn't do anything unless you leave wifi on all the time, and if you do then that would be one solution to this problem.

I experienced the exact same issue after doing the battery thing yesterday. Tried several different kernals since then - no change: I could just about watch the battery go down. This morning I wiped and loaded SR Sense 2.5.2 and the updated stock kernal from ROM manager. We'll see how it goes...

I did this and just installed 2.5.2. I then installed the Hydra kernel and wiped battery stats when I was at 100% and the unit was off/green light. The battery has gone to crap too. Any ideas?
thats weird, i did wipe battery stats (correctly) at 11 last night. i woke up at 9:30 (lol) with 93% battery left. the phone was sleeping the whole time, but i had sync turned on and had recieved several facebook updates, txts, and emails. now im losing around 10%battery every two hours or so, and i am using the phone to send txts and emails every three to five minutes. so battery life is actually much better. after the cable is unplugged, is it necessary to let the battery die fully, then charge, or can i charge it now? (its at around 30%)
so basically, i was wondering if it is necessary to run your battery fully down after doing a wipe battery stats
I don't know what to tell you guys. Since wiping stats, my phone has been up for 36 consecutive hours with an awake time of 2:40 and the battery is at 30%.
For reference I guess....

Great question. Anyone have any knowledge on this? I didn't let mine discharge all the way.
I do have some kind of update. I had to do a factory wipe today and since I did that my battery life has been much better.

It's completely impossible for wiping your battery stats to make your battery life worse. It's a common misconception that by wiping your battery stats you somehow condition your battery. It's actually quite the opposite, because you're actually conditioning Android by wiping your stats. No matter what your battery percentage or meter says, your battery is still capable of holding a certain amount of electrical charge and your phone will not die until it's fully discharged. On the other hand it *might* make your percentage or battery meter read wrong if you either:
a. wiped your battery stats without a full bump charge (e.g. wiping your stats at 60% charge *might* make your phone think 60%=100% and as a result, you'd see huge decreases. but, you would most likely sit there with a phone showing a 1% charge for hours after it got there.)
b: didn't allow your phone to discharge fully after wiping your stats (same problem as example a, but the inverse of it)
All wiping your battery stats does is delete the file "batterystats.bin" from your /data/system folder. This file is recreated when you boot your phone after wiping them. It keeps the data on what's using your battery for when you click "battery use" in the settings menu. It's also thought to hold the stats that tell you phone what a full charge and no charge feels like and that if you fully bump charge your phone, wipe that battery stats, and then full discharge your phone (without interrupting it by switching ROMs or doing updates) that you will have a more accurate battery meter. It won't eliminate the need to bump charge your phone or make your battery life better. It will just be perceived as better since you won't get 20% drops in your reading in 30 minutes due to a badly calibrated batterystats.bin file. Also, you'll feel better because instead of looking at a 50% reading, you'll be looking at 60%.
Your battery still has the same capacity, charges to the same level, and discharges in the same amount of time. The only thing that can change those things are usage levels.
so should i redo my wipe battery stats then? when i originally did it, i ran it down to around 40%, then rebooted, then i plugged it in around 15%. would this mess it up then?

Do you know how we can see what's inside the actual batterystats.bin file? I tried in root explorer and cannot open in no matter how I try.
i dont care what vantagejuan says, when i tried this process...and did it correctly, my battery was down to 85% within an hour..i know this because i unplugged it when i woke up for work, and i when i clocked in, it was at 85%
it was never this bad, i tried locating the file again from an old backup, but it didnt help...im hoping that like someone else said, a couple cycles through it will get better
im using the skyraider 2.5.2 vanilla with the hydra oc/uv kernal
i had this setup before AND after trying the battery fix and im using the seidio 1750...
frustrations are back from when i first got the phone

Battery life sucks after Trigger 2.9.2 flash...

... and from what I'm reading, trigger gives great battery life. So how do I see what has been eating my battery life up? For instance, I unplugged 40 minutes ago and I am down to 91% already.
The regular option on the phone doesn't do a great job of troubleshooting this issue and just says "Display" and "Cell standby" as the relative battery use culprits. I figure, though, that this must be something I downloaded that is killing the battery. I love the ROM overall, but if this battery issue can't be resolved, I need to find something else quick. I'm a slave to a charge port.
Thanks.

Have you tried conditioned your battery by wiping your battery stats.bin? Why didn't you flash the newest Trigger?
Yeah, you need multiple cycles for battery to be even close to accurate, and you should recalibrate.
Are you using other kernels or themes?

Let your phone die wipe battery stats in recovery mode. charge to 100% then use the battery calibration app from the market and re-calibrate the battery. I always repeat the process. Sometimes when flashing new ROMs your batterystats.bin can get a little funky so I always do this after flashing a ROM and my battery works great.
Definitely check the Kernel and Modem your running if there not the ones that came with Trigger than that could be causing your problem as well.
From what i have got from prior experiences. Using odin to go to stock as if your phone just came out of the box and then flashing removes all the old files. When i did this i went from getting almost 10 hours... now my phone gets 17 normal and if i dont use it as much as a normal day it iwll hit 24 hours no problem.

This post (http://forum.xda-developers.com/showthread.php?t=806022) is saying to wipe battery stats at full charge... So what is it?
And why didn't I flash the newest version? It was when I flashed it.
What was the use in the 40 minutes after charge? I could see that if you had screen brightness high, and lots of wifi surfing or video use. I downloaded an app called 'screen filter' and it lets me lower the brightness lower than stock and I have noticed significant battery length increase since use. The stock dim options are not enough. Its still too bright and a waste of battery.

Both. I wipe mine at 0 and at 100 but once you wipe make sure you fully charge without interuption and vice-versa

same here, and i suggest you do the charging during night when your sleeping, so then there'll be no interruptions, like having to reboot for some odd reason etc. That can disturb the process of recalibration/conditioning.

Pretty much nothing... Maybe looked at Facebook once and replied to a text?
So I drained it, wiped the battery stats, then looked at what it was doing - probably 1 minute after it was totally dead and wiped. The screen said it was at 14% already.
In less than a minute - 14%...

Let it die again and wipe again. Your stats are off from the flash its normal. Just let completely die wipe charge wipe repeat. It will take a couple times normally to get back 100% right

I used to chage my battery overnight with good results but since going to gingerbread it usually drops from 90-100% whne unplugging. was reading up and found out it's saftey feature created by Sammy.

Battery Life After CWM Recovery Restore

Hey Guys, i have noticed before i did my restore through CWM Recovery that my battery life was at 30% and after the restore it jumped up to 73%!!!! After that i was skeptical about what the restore has done and i am seeing a discrepancy in my battery life before and after =/
Any reason for this?
I also tried wiping my battery stats and doing a battery calibration through Nemu's app (Battery Calibration) and still the battery is nothing to what it was before. Before it would go a whole day before i needed to charge it and when i did charge it at the end of the day it would be at 20% or so with heavy use and a lot of phone call time, but now the battery life only sustains for about half a day if that with very minimal use and light talking, in fact it drains at about 10% every 2-3 hours when i have the screen off...
Any hints on as to why and how to prevent this again should i do a restore through CWM Recovery?
I noticed a similar effect with my Atrix 4G, however I forgot about it until I saw this topic.
Not sure why it does this but I have noticed similar results multiple times. After any wipe or restore I try to do a full charge with the phone off. This seems to help, or at least gives me peace of mind...

well going from 33% to 70% could be normal since recovery replace the charge .bin so you are actaully charging you device. try pull the battery an recharge,
maybe there is a rogue app try start "freezing" som apps one by one and check battery
didn't realize it was that extreme, but ^ is right, you're charging while you mess around in CWM. i went from ~15% to 40% on the next boot while reinstalling GB 3.5

Extended battery discharge oddities

Hello,
I have extended battery in my Atrix and I see it going from 100% to 50% in like 4 hours. Then I shutdown Atrix, boot it up and battery shows 88%. What can be causing it? Is it battery or OS?

Probably just compatibility issues. I do suggest running a battery calibration app or clearing battery stats in CWM.

Nexus 7 Battery issues

Haven't switched from the OEM charging cord so I don't know why my battery meter showed that I remained at 22% for more than 3 hours...
All day yesterday the only time the percentage would go above that was when I put the tablet down completely, killed all apps and processes and shut off wifi....I've never had to do so much just to see an increase So I attempted to recalibrate and wipe battery stats in cwm for the first time as I have done on all my other devices...
With most if not all devices the fastest way to charge is with the device powered off....for the strangest reason the N7 charges faster with the power on. Ive had this thing plugged in for 5 hours from a fully discharged state and the batter meter only reads half....whats taking so long? With the device on all i need is 2.5-3 hours....Can someone explain this as i have combed Google search like mad looking for an answer...

Looks like you missed the memo...
Wiping battery stats does not affect battery indication in any way, shape, or form, nor can you actually ”recalibrate” your battery. The misinformation regarding wiping battery stats was emphatically debunked by Google's Android team about a year ago.
Rather than wasting time with snake oil such as ”calibration” and wiping battery stats, more viable solutions are a factory reset or ensuring your battery connector is fully seated on the mainboard.
