For about the last 3 weeks my phone will not charge to 100%. It'll get to about 80% and that's it. Last night I got my new battery and a stand alone wall charger. I charged the new battery in the stand alone charger and put it in the phone and it reads 87%. I put the battery back in the stand alone charger and it says fully charged so I check the battery with my meters and it reads 4.195 volts and from what I've read 4200 mv is fully charged, 4.195 v is reeeeeeeeally close to a full charge. Can anybody tell me how to fix this? Is it a hardware problem? Does the phone not read voltages right? I just installed shiftao5p rom last night and still the same problem. I've read of a few others having this problem but have yet to find a fix for it. Don't tell me to calibrate the battery because I CAN NOT get to 100% so I can be able to calibrate.
If you have clockworkmod recovery you can calibrate from there. Make sure your battery is completely charged in your stand alone then go into recovery and choose erase battery stats, its in the advanced menu I believe. That might work for you. Good luck.

I was gonna try that when I got home tonight. After I clear battery stats in clockwork should I leave it unplugged and let it drain to zero then try to charge back to 100%?

The charge percentage is reported as based upon battery stats. Let me explain how your battery stats may lead to some weird readings...
Lets say you've got a battery that charges to 4.2V. As it discharges, it drops off uncharacteristically slow. Then, you use a battery where the voltage drop is more linear. The stats have determined that over the life of the old battery the voltage remains fairly flat for the first 15% to 20% or so, but the new battery drops off a bit quicker so it's going to look at that voltage drop as a sudden drop in charge capacity.
This situation can be aggravated my many factors. If your battery is reading a full charge, which it sounds like it is based upon your meter readings, then the next question to ask is whether the battery is achieving the life it should based on it's mAh rating. I'd be curious to see what the battery voltage is once it's flat dead. If it's not reading somewhere around 3.6 to 3.7 volts, then the phone probably is defective and not reading voltage properly. If it is reading that kind of voltage, then it's just an annoyance and hopefully battery stat wiping will remedy it.
i can leave my phone on the charger for hours and it will only get to 99%, then it takes another hour or so to read "fully charged"

Yes let it drain all the way till you phone shuts it self off then charge it back up to 100% again in the phone. Hopefully your phone will build the correct stats. If your phone isn't defective it should work for you. Hope all goes well.

Something else odd......the battery I'm using right now is a cheap Chinese eBay battery, 3500 mAh. It ran down to about 10% in about 3 hours so I pulled it and put in a fresh one. So I decided to put it back in and run it all the way down and then check the voltage on it. That was an hour ago when I put it in. It quickly dropped from 8% to 2% in about 10 minutes but since then I've been using the phone solid without a break trying to shut the phone off and it has not moved off 2% in about 45 minutes. Very odd.

One more thing, I do not recommended these cheap azz eBay batteries or there extended battery covers. As you know the 4g and GPS antenna is in the battey cover and these cheaper one do not work. I got the batteries and cover last night and as soon as I put one in and turned the phone on it immediately went to 1x. I finally figured out it was the antenna, or lack thereof, so I modified it to get it to work. Pure junk. I normally go with seidio stuff and will buy nothing but that from now on.

It finally shut off after sitting on 2% for an hour of solid use on the web, Facebook and youtube. The voltage is 3.682.

Don't know if you looked, but the batteries HTC uses are cheap Chinese junk, which is why I tell people to not replace HTC batteries with HTC batteries. Better can be had.
As for the LTE antenna, the Tbolt doesn't have just one. The LTE spec requires dual antennas. The second antenna is located in the bottom of the phone underneath the ligher colored portion. LTE reception should roll over to that antenna if the other one is some how encumbered.
That voltage looks about right. And it appears the phone detected it correctly and took the correct action. Hopefully a wipe of stats fixes things.
All I know is before I modified the antenna 4g would drop in and out constantly then it would drop to 3g and it was in and out til it finally settled on 1x. After I modified it it stayed on 4g all night with a decent dl speed.
I hope this fixes it but I've wiped stats 20 times this week in clockwork and a battery cal app with no change but I didn't get the stand alone charger til last night so fingers crossed.
I'm sorry... flat dead voltage should be around 3.1 to 3.2. If you're phone is shutting off at 3.6v, it probably isn't reading voltage correctly.

Any suggestions? What I don't understand is why it would charge fine for the first month that I had it.
Wish I had something wise to say, but I don't.
I charged it in the phone with it off all night, about 7 hours, and it shows 4.17 volts on the meter but it only showed 88% charge when I turned the phone on. Are you sure about the dead flat voltage? Is this just for the thunderbolt or droids in general? The reason I ask is because I ran down my incredible until it shut off and the voltage on it was 3.7, pretty close to the thunderbolt battery ran down. I think I'm getting the full use of my battery on the tbolt, the phone just wont show the correct voltage for some reason. Somebody needs to make an app that allows you to offset between what the battery voltage actually is and what the phone displays.

3.163 volts is what my Tbolt calls flat dead. I've never meter tested the battery, but that sounds right to me. 3.7 is the nominal voltage; a mean between the min and max. If someone else could confirm what I'm saying, that would be helpful. If you like I can post some screen shots of the app I'm getting that data from.

I would rather have a meter reading on it. Last night I kept checking voltage with my app and just before it went dead it was showing about 3.3 to 3.4 volts but the meter said 3.6. I'm sure it might read a lil lower with the app since it has a load on it but I don't trust the apps. A good meter wont lie.

That would be great. The stock battery is doing the same thing the other did last night. Its been sitting on 2% for about 2 hours and an hour of that was of heavy use. I dl a battery monitor and it graphs over time and the voltage has not moved off of 3.511 in at least 2 hours. This is messed up.
I hope someone can figure this out, My (used) TBolt has been like this since I got it, now my wifes just started not charging to 100% 2 days ago, looks like she has the same issue...
Ive tried the wiping bat stats, loading roms, different batteries, chargers, etc...
Nothing has fixed it yet... just having to live with it...
hoping by some miracle the 2.3 OTA may fix it.... (but not holding my breadth)

My Thunderbolt will no longer charge to full, no matter what I do. Already had a replacement battery sent, hard reset, nothing. Tried with the phone on and completely powered down. At best I can get it to about 90%. With not so great battery to begin with really hate starting 10% down. Any ideas what might be causing this/how to fix it?
If rooted. Try wiping battery stats.
Not rooted, I've actually been fine staying unrooted on stock for now. Any way to wipe the stats without being rooted?

I've been in this boat for a few months now as are a lot of other tbolt owners. I've read many threads in several forums about this exact same problem. It started out charging fine then it would only go to 89% then 69% then 50% and now it might be 69% or any other number. It's actually charging the phone to 100% because I've checked it with a meter after an overnight charge. It'll check at 4.2 volts but for some reason some tbolts don't read the correct voltage. In a battery app it reads about .2 - .3 volts lower than what the battery actually is at and of course this causes terrible battery life. Like today, I checked voltage on a fully charged battery with a meter and it was at 4.2 volts but when I put the battery in the phone it says it was at 3.914 volts so we are already starting out with what the phone thinks is a half dead battery. That battery (a 3500 mah battery) lasted about 3 hours til the phone shut down and the battery app said it was at 3.55 volts just before it shut down. I pulled the battery and it checked at 3.845 volts so I lost quite a bit of use from that battery. I've done all I know to do including wiping battery stats with clockwork, batter calibration apps and doing it manually with root explorer and nothing changes it. I've tried every single Rom and kernel on the Rom and kernel page in this forum and the only difference I have noticed is the gingerbread roms make the battery last a lil longer but the voltage readings are still way off. I'm wondering if a custom kernel for tbolts that act this way would help. I might start another thread asking this question.

Forgot to mention, I'm now on my second 3500 mah battery for today and it started out at 69% according to the phone but checked at 4.2 volts with a meter. 4.2 volts by the way is fully charged. I'm not really sure what the voltage should be when the phone dies but I think it's around 3.4 - 3.5 volts. 1.5 hours later I'm at 21% at 3.665 volts. I bet if I pulled the battery and checked it with a meter it will read close to .3 volts higher than 3.665. I love the phone and usually get 15+ mbps download speed and with an aosp Rom its super fast but this problems sucks balls badly.
I've actually been getting it to charge fully, on occasion. Charging it overnight puts it in the 80-90% range, and if I restart it plugged into a charger it usually hits 100%. Not all the time, but it's better than nothing I guess. Still hate to send it in for a crappy refurb replacement phone.
When I charge my phone it only charges to 99%. I'll leave it in for a while, come back and it's only at 99%. Either charging in the wall, or on the computer. It used to make it to 100% then all of a sudden it just stays at 99% regardless how long it charges. So the charging light always stays on and never lets me know when it's fully charged.
Any idea why?
Thanks.
Mine does that too once in a while, randomly.
But the Sensation would do that to randomly.
Dunno why.
Battery is strange...
I get that too. But eventually it will get to 100%. There has been times where it was charged to 100% then suddenly drop to 99% even though it still plugged in.
Did you get your phone recently? I'm thinking its because the battery needs to be conditioned.
Mines always does that, as soon as I unplug it it jumps to 98%. Im hoping ARHD fixes this
I've installed Battery Widget (from Market) and it reports 100%. I plug in every night and in the morning it reads 100%.

New Amaze Android Revolution HD ROM by mike1986?
This happens with many devices. I have not seen this yet on my Amaze but I am sure at some point it will happen. Try turning the phone off and charging it to 100% then power it on also try running the battery all the way down and letting it charge to full UNINTERRUPTED over night. If those dont help you can always try another rom with better battery management or go into a t-mobile store and get a battery replacement if your battery is still under warranty. Hope this helps
HTC does this on a lot of phones. It is a safety default to keep the battery healthy and safe. I had this issue with the Evo. The only way to fully charge a battery is to have other a wall charger or a SBC kernel.
its the best sense rom known to man in my opinion.

My stock battery is 3.8v, and it only goes to 100% if I charge it in the phone. If I use my wall charger, it shows up at 99% when I put it back in my phone. I have two aftermarket batteries that show about 98% when charged from the wall. I am thinking that the phone charging circuit is set for 3.8v, and might possibly overheat the aftermarket batteries (3.7v). I saw one review that said these batteries melted the top of his SIM card. I'm not planning on trying that; I use the stock, charging every night, and swap the spares in if I run out of charge during the day.
I just remember hearing the same stories when I had my evo. You could charge for hours and unplug it and it would almost immediately drop to 99 or 98. So my previous statement may or may not help.
I charged mine over nite and woke up to it being 99%, left it for another hour or two and it hit 100%. I would say to leave it a little longer to get that last 1%.

this is normal for lithium ion batteries...it also depends how the manufacturer perceives the battery...some manufeacturers say that your phone is 100 percent but it might only be around 95-98...overcharging lithium ions are bad...also some manufacturers say you have 10 percent left while you might actually have 15 or maybe to percent left...this is a fail safe method to shut off the phone and keep the battery from draining completely WHICH IS REALLY REALLY BAD FOR LITHIUM IONS...OVER CHARGING THE BATTERY IS BAD TOO...perhaps htc's thresh holds are a little different and actual to the real battery life.
also not a good idea to use your phone or any lithium ion device while its charging
powering off your phone to charge it overnight is the best idea to give you lithium ion a long life but this is not practical. this is why it says 100 percent when you turn off the phone and 99 when you're phone is off....it confuses the phone: " A portable device must be turned off during charge. This allows the battery to reach the set threshold voltage unhindered, and enables terminating charge on low current. A parasitic load (which means using phone or turning screen on while its charging) confuses the charger by depressing the battery voltage and preventing the current in the saturation stage to drop low. A battery may be fully charged, but the prevailing conditions prompt a continued charge. This causes undue battery stress and compromises safety."

I thought I would bring some info I highly pushed with the Thunderbolt and Evo 4G that applies here. IF YOU HAVE THE EXTENDED BATTERY, YOU WILL WANT TO DO THIS SO YOUR PHONE UTILIZES THE ENTIRE EXTENDED BATTERY. The phone comes with a smaller battery, so it's batterystats.bin file is set to see that battery. It may not charge your extended battery all the way as it will think it is done charging much sooner than it is. Not that you won't get longer battery life without doing this, but you can always get MOAR!
**Disclaimer**I am not responsible for anything you do to your phone, zombie apocalypse, or the fact your phone called your girl/guy at the wrong time**As always your mileage will vary, some phones work better than others**
This is a form of bump charging your phones. I used it today, and noticed beyond better battery life immediately. So let us get down to business.
[Step 1] You will need to plug the phone into your charger, and charge the phone until the Notification light turns green.
[Step 2] Unplug the charger, wait for the green light to go out, plug the charger back in and wait for the light to turn green again. Upon doing so, turn the phone off. You will need to have fast boot OFF.
[Step 3] Once the phone is off, wait for the light to turn green, and unplug your charger, wait for the green light to go out, and plug back in. Repeat this step for a total of 10 unplug, plug back ins. Don't panick if sometimes it takes much longer than other times to turn green. You are charging the battery past the "capacity" that batterystats.bin says the battery has, which we will come back to in a min. Power on your phone. If you do not, or cannot temp root skip step 4
[Step 4] If you are able to temp root, then you can make your battery even better. Using a root explorer, go to data/system/ and delete the file batterystats.bin and reboot your phone. DO NOT use any battery calibration apps from the market, and down the road when we get S-OFF Clockwork Mod to wipe the battery stats. There is a known issue with CWM where it doesn't work, and I have tested a few calibration apps that say they delete batterystats.bin, but the file is always there, with the same data in it after using the app. Only way I have seen that works is manually deleting it.
[Step 5] The Hardest part of all. Use your phone, do not plug the phone in once, until it hits the 15% mark and asks you to. Once you do plug it into charge, let it charge all the way back up. You are building the batterystats.bin file so it understands how much charge your battery can actually hold. FUTURE REFERENCE: you will need to do this everytime you factory reset the phone, everytime you flash a new rom, etc. I know we cannot do all this currently, but this guide will still provide usefulness down the road when we get S-OFF as you will want to calibrate the battery the same way.
****If there is anything you noticed i put in wrong, or questions let me know***HTC has supported this method, minus deleting batterystats on many of their phones, and yet again seems to work on the rezound as well.****
Or you could just download the free battery monitor widget by 3c and you will notice your green light turn on at "100%" but keep an eye on the mA being pushed into the phone. When the mA goes from a positive (green number) to a negative (red number) that's when you should unplug. You will notice that your rezound "thinks" its 100% about 10-25 min before it really is... Much easier than feeling tweeked out, plugging and unplugging multiple times. Just another option. Good post though for sure. As most would NOT benefit from the full extended potential the battery has to offer.

when the mA goes red though, is based off the batterstats.bin file. I was not even talking about when to unplug the phone. I am talking about allowing the android OS to see how battery it actually has to use. so you are talking about something different than I am.
**edit** wanted to add. Your phone hitting 100% may in all reality only be hitting say 95% for example, but your phone thinks it is 100% hence why you can turn your phone off when at 100% and it continues to charge.

haha read it now. Was unaware that the rezound knew to keep charging. The Tbolt never did(atleast in the beginning as i stopped using it for awhile), and the Evo 4G never did either. I never thought to check this as HTC themselves never made mention of it charging past "100%" on its own.

I did the battery stats fix with my Inc a long time ago. When I popped on the Rezound extended battery I plugged in the charger and it took 4 hours to charge vs about 1 for the original. Now at the end of a full day I have about 70% left, so I'm pretty sure the Rezound is much better about figuring out battery stats then older HTC's. IMHO. I'd love to see some data to back me up though.

So, step 2 turn the phone off at the end. after step 3. u say to reboot?? so if the phone is already off.. u mean to turn it on. then turn it off? kinda doesnt make any sense. Unless by reboot, you mean to just simply turn the phone on. in which, u should probably word it "Power Up" not reboot.
so confused lol
Lithium batteries are charged by monitoring voltage first. The phone can monitor the mAh going in and out, but it really has no bearing on the charging. It does allow the phone to monitor the health of the battery by watching for capacity changes as it ages.
Bump charging gives a slight overcharge, this is why the battery lasts a little longer. Charging with the phone off is best for calibrating the battery stats and for battery life because the phone can actually fully charge the battery. It is not possible to fully charge the battery when the phone is powered on as the battery is in use.
Here is a link to a post I made about lithium type batteries and how they charge and the reasons for calibration. It should clear up some things about the batteries.
You can do a bit of a bump charge by charging the battery with the phone off, then when the LED turns green, pull the charger and let the battery settle a few minutes then plug it back in. The LED should not be green and it will charge at the fast constant voltage rate for a bit more. Let it charge about another hour then unplug, wait a few minutes and re-plug it in again. This can force in a few extra mAh.

So, step 2 turn the phone off at the end. after step 3. u say to reboot?? so if the phone is already off.. u mean to turn it on. then turn it off? kinda doesnt make any sense. Unless by reboot, you mean to just simply turn the phone on. in which, u should probably word it "Power Up" not reboot.
so confused lol

yeah I meant turn it on lol...sorry for the confusion. I will fix the OP

Lithium batteries are charged by monitoring voltage first. The phone can monitor the mAh going in and out, but it really has no bearing on the charging. It does allow the phone to monitor the health of the battery by watching for capacity changes as it ages.
Bump charging gives a slight overcharge, this is why the battery lasts a little longer. Charging with the phone off is best for calibrating the battery stats and for battery life because the phone can actually fully charge the battery. It is not possible to fully charge the battery when the phone is powered on as the battery is in use.
Here is a link to a post I made about lithium type batteries and how they charge and the reasons for calibration. It should clear up some things about the batteries.
You can do a bit of a bump charge by charging the battery with the phone off, then when the LED turns green, pull the charger and let the battery settle a few minutes then plug it back in. The LED should not be green and it will charge at the fast constant voltage rate for a bit more. Let it charge about another hour then unplug, wait a few minutes and re-plug it in again. This can force in a few extra mAh.

I'll be honest I haven't looked at exactly how much of a change it results on the Rezound, but on the Evo 4G for example, we got more than a "few" extra mAh. I am glad to see someone agree with me, to an extent. I will say the way I listed it is the way provided by HTC back when the Evo came out. What you said to do, we tried with the Evo 4G and it didn't work quite as well. Maybe that is why you say only a few mAh.
The one thing I have missed from my Evo 4G days are the trickle charge kernels. I know everyone thought they were bad, but no one ever had real proof of them damaging a phone, hell I used trickle charging kernels only for well over a month everyday and never had any issues. I would love to see those come to the Rezound.
I did every trick in the book to increase battery life in my Droid Charge (bump charge, deleting batterstats.bin etc etc etc) .
I stream audio all day at work from either iheart radio or sirius online & that absolutely KILLS battery life. My Charge would kill a 3500 extended battery before the end of a long work day.
Now, I am getting awesome battery life from the 2750 extended battery on the Rezound. I bought two of the 2750 batteries with the phone as they where only $29 each at the time with the extended back.
I did no tricks at all other than fully charge and let it run down to about 2% a couple times. I have been using this phone the exact same way as the Charge & I have yet to go to the second battery. I stream all day & its still running when I walk in the house at the end of a LONG work day.

Good lord, am I the only one that doesn't look at their phone while it's charging? I prefer to be asleep and let it suck as much power as it can. I will try your method, but you might want to mention to use the stock charger, since it's been my experience that it's the only thing that actually charges the phone properly.

Well that is because the charger that comes with the phone is 1 amp, versus the charger say I bought to use in my car is about half an amp. Cause it was meant for older phones. same as using USB. USB will take forever to charge your phone.

Are you on 4g or 3g? With my extended battery and a full charge my phone will be dead after 10 hrs with hardly any use

4g.
I'm totally amazed at the battery life I'm getting. The reason I bought two extended batteries was because I figured I needed them.
I have had a ton of phones and not one of them could stream audio for 10hours straight, I don't care what battery you used.
Today, I went to work at around 8 am. I streamed both iheart radio and Sirius radio online for almost the entire day. When I got home around 6 pm it was running on fumes, but it hadn't shut down yet.
If I didn't stream anything it would run for days I think.

I don't understand why I'm getting so much battery life on this phone. It's exceeding expectations. Not that I'm complaining, but my experiences simply are not jiving with the results found by reviews like Engadget's. I have the official extended battery which is 2750MAh, but I had a 35**MAh one for my Droid X and it died faster under the same use. Considering I never lose LTE signal at home/work, and everything I do over it at work is using LTE, I just can't fathom how this MOTHER-F***ING BEAST of an amazing phone lasts like 20% longer on a 30% smaller battery over my Droid X. (I'm not going by the battery life indicator, but purposely letting it die so I know for certain.)
Also, yes, I understand they were using stock battery in the reviews; but I used that the first few days before going back and picking up an extended battery @ half off normal price.
I love this thing, and I love HTC for having a 1% battery indicator on the stock device.
Oh, by the way; should I really plug it in at 15% remaining? I thought you were supposed to let it die when training new battery life?

Add a battery indicator widget; it goes in 1% increments. I'd LOVE it if you could have it show on the actual indicator on the notification bar, but I haven't found a way to do that; but I keep a battery life indicator on my main home screen, and yeah, 1% increments for the win.
My htc amaze doesn't display battery % correctly all the time.
How can I calibrate my battery? I see a bunch of methods but Im not sure whats best for the amaze
Im useing bulletproof 2.1.0 and faux .008 beta 4
thanks!
what has worked for me with bulletproof is to drain the battery to under 15%, charge it overnight, boot into recovery and wipe the battery stats.
will try it, thanks

so i figured out that my phone doesn't read my battery life correctly anymore, it will be at 39% and shut down, then i turn on my phone it will have 4% and itll turn off right away so i plug in my charger and it'll have 55%
dont really understand whats going on any help?
I just used this app and it worked, it reads the percentage just fine
https://market.android.com/details?id=com.nema.batterycalibration&hl=en
I havent been able to get my battery to stay at 100%, just says 99% and i have to guess when its fully charged. wiped battery stats and everything. running the same ROM

As the app says, all it does it delete the batterystats file. Use root explorer and go delete /data/system/batterystats.bin and you accomplished the same thing as that "app"

I get the same thing.. and because the device doesn't die all the way(at about 1% it does a soft power off) I can't get it calibrated right.
I'm using senseless, and I think it is more than the battery stats file.. tonight it was at 40%, started bootlooping for no apparent reason.. pulled the battery, rebooted and it said it was at 13%.
It has been a solid rom in a lot of senses(pun?), but I may try something else because of the quirks it has been having..

thats what was happening to me, i did a full wipe, using bulletproof, then calibrate, Im still testing but so far it reads fine, will update if everything is working fine in a couple of days.
another method is abit troublesome...
1. charge your phone battery till full (off mode)
2.when full unplug it, and open up the cover
3. take off the battery and left it there over 90sec or more..
4. put back the battery n bootup your phone.. it should calibrate..
if your battery is used too long it might your battery problem

I might try this. My battery indicator stays at 100% for like ten seconds or maybe longer then goes back down to 99%. Makes no sense lol

I'm only a two week owner of the Amaze, but I've found curious differences between the stock battery and the Anker (1900 mAh). First, the stock battery will remain at 100% for a fair length of time before starting to drop (sorry, I haven't quantified it, but it's easily half hour to 45 mins even after making a call or two). However, the Anker battery drops off of 100% pretty quickly, as little as 10 minutes without doing anything. Admittedly, I've cycled the stock battery a few more times than the Anker, and even Anker says it takes 4 to 5 full charge and discharges to reach best performance, but I don't recall the stock being that quick to drop even after the 1st full charge. I haven't used the Anker enough yet to have a feel of whether the Anker will last longer overall, though.
Off topic, but somewhat related - The Anker charger doesn't seem to charge the battery to a full 100% - either the Anker battery or the original. In both cases, as soon as I install the battery from the Anker charger, the Amaze meter indicates just 96%. I even left it plugged in for another hour after the light turned blue, but it didn't help. Not a biggie, just an observation.
BTW, I got this from someone else who had already posted it, but according to a Google Engineer it seems that resetting battery statistics doesn't help. Read about it here: http://www.androidcentral.com/wiping-battery-stats-doesnt-improve-battery-life-says-google-engineer

exactly lol. my battery will stay at 100% (99% according to bulletproof) for a long time then once it drops it drops fast
I left my phone off while charging, and I'm having good results.. only weird thing is that it slowly flashes on and off the orange light and never shows green while powered *off* and on the charger.. I can't find anything that shows this is normal. Is it supposed to get to a green light when powered off and charging?

Hi again
I know this is a well know issue but i wanted to ask something about the batteries and this problem. For some reason when i bought my Atrix it came with the bh5x, but i bought a bh6x after a few months. The problem is that when i started flashing roms the battery stopped charging to 100% with the bh6x, in some roms it charges to 93%, sometimes to 72%, etc; but my stock battery every time charges up to 100%. I know it may sound crazy, how can batteries affect this percentage since the charge it's the same, only the mAh.
The bh6x charges up to 100% (my phones says) when i charge it with the wall charger. I'm now using the bh6x in case of i ran out of battery with the bh5x because for some reason, using the bh6x while charged with the external charger, my camera stops working, it force closes. At the beginning i thought that this could be just coincidence, but i haven't had that problem since i put the bh5x as the primary one.
For me it doesn't make sense that the stock one charges full, and the bh6x(original) doesn't. I thought that there could be some file or configuration on the phone that i've not seen, i'm not a professional in this rom stuff, but i know at least the basics.
Has someone experienced something like this?

Yeah, i know that there is a fix for that, but that was not the question, otherwise i would just download it over again. The intrigue here was that it's akward that my stock battery( bh5x) charges always to 100% without problems, but my replacement battery(bh6x) doesn't and when i charge with the wall charger it seems to cause problems with the camera, i just wanted to see if someone had the same problem, or even just the one in the camera....
I believe everyone got their atrix with the bh6x, don't know why mine came with bh5x...
Well, I have bh6x.
The battery was always charging to 100%
Untill last Tuesday.
I am on epinter's JellyBean, I was getting up to 30hrs of battery life. On Tuesday I dropped my phone, not a big hit but enought to cause the battery fell off. It was at around 75% at the time. Once I put it back in it showed 1%. Wipe stats, rebooting, nothing changed. Now after a full night of charging the meter shows 30% max. The battery seems to be fully charged as the batt calibration shows 4200mAh and the battery still lasts a very long time it just reports the wrong percentage.
Anyone knows what could cause it and how to fix it?

Well, i think you are in the case that upndwn4par said. For that there is a post in the developer section that is called Atrix battery fix, something like that, you can search it.
There are some other methods in another post that consisted in charging and disconnect the battery from the phone and wait for the question mark to appear in the screen, then putting it back again and let it charge for a while, after that it will show you 100%, but for me it only worked for 1 time. I think the post is called something like " The ultimate battery guide" .... i can't remember exactly the title
