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%.

For anyone who is running quicksense, if you want better battery life, charge your phone completely and go into recovery > Advanced> wipe battery stats. And done!

I find that if my phone its powered off while charging, it shows 100. If powered on, it shoes 99.
Sent from my Dell Streak 7 using xda premium
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'm a truck driver, I work 12-16 hours a day. I use my bolt to listen to my hometown radio shows, and slacker when they aren't on.
Is it a bad thing to have it plugged in all day? I read once its fully charged it runs off the charger power..
Thoughts?

Someone did a test and after being fully charged the phone resorts to a trickle charge so you should be okay but probably.not the best thing for your battery.

so i came from the evo 4G where people threw hissy fits both ways. There were people who would claim left and right that it is bad for the battery, that the battery will catch fire, melt, explode, what have you, and then there was the other like 80% of us who used trickle charging with out a problem.
personally, and what I seemed to notice, the like 6 people who actually claimed to have issues with trickle charging had purchased and were using super cheap chinese batteries.
So i am going to disagree, and say there will be no issue with trickle charging unless you start using cheap chinese batteries, and even then the percentage chance of you having an issue is so minor.
I have noticed that until it gets to 100% it gets awfully hot. If I leave it charged/plugged in all day its cool to the touch.

looking at battery monitor widget my phone after hitting 100% charge is pulling 180 or less mA while "idle" and the temp sits about 32-33C. Seems to keep the Voltage very very steady. Whatever HTC did I really doubt it will hurt your phone in anyway.
I don't think it will hurt the phone. I do think it will make the battery have even less life though. I.e, when you finally do unplug it, the battery won't last very long. Batteries need to be charged and discharged often to work well.
My laptop at home stays plugged in all the time. And when I unplug it, it lasts about 10 minutes on the battery. lol

No, my statement was 100% true. It might've been irrelevant because it's a different type of battery, but it was not false as you said.
I have read that LiOn batteries do not develop memories as bad as other types, but they still do to some extent. FWIW.
If you watch your phone, it stops charging when its full. I often pull the phone off the charger with less then 100 charge due to this and this is also why the bump charge will bump it back up too 100%
So leaving it plugged in ask day will have no harmful effects at all.

actually battery monitor widget says the opposite. My phone continues to charge after hitting 100%. It doesn't do what my evo would do stock, where it would charge to 100%, let the phone die to 90% and then charge back to 100%.

Personally I never shut my phone off, it's on 24/7/365, if I don't want to be bothered it goes into silent mode but is always on.
For me, I plug the phone in every night when I go to bed... when I wake up, I unplug it for a minute and then plug it back in. Normally when I wake up it's anywhere between 95-100% showing.... Once I'm done getting ready I grab the phone and off I go with a full charged battery.
Unlike some phones the android phones have never kept a 100% charge while plugged in... this is one thing I do miss from the iphone, it always kept it at 100% while plugged in. The android phones stop charging when it get's to 100% and start again at an unkown %.
There is no magic... the only reason for unplulgging it is to start the charging process again.
what's the exact name and publisher of that battery widget? i'd like to take a look at it.

Use the built in battery widget and see what you get.. it will display the actual percentage on the screen.
I doubt it's a problem, it should be capable of switching to a trickle or over to powering vs. charging in the circuitry. The worst thing you can do for these relative to the charge is drain them completely and let them sit drained. These days for the longest life, you'd keep it at around 3/4 charged, but it's not a huge difference in life usually. The reason for that is lithium batteries hold a native charge by default.

They do not have memory. I dug up an old article I wrote nearly 6 years ago where I touch on that fact even notebookforums.com/thread94560.html
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.

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.

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.
This was common on my droid x for so long while flashing but is it a good form of practice on the Rezound? The reason I am asking is I flashed Bamfs Cubed rom and my charging led goes from orange to green at 98%, never making it to 100. Would it be wise to go ahead and wipe battery stats and see if it fixes it? I presume there would be no harm to the system or battery in doing this.
Thanks!

There's really no harm in doing it but Google has come out and said that wiping battery stats doesn't do anything.
http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
I always got a good laugh when people would post how "bump charging" & then deleting this file gave them an immediate dramatic increase in battery life.
This has to be the ultimate placebo effect.........

Don't agree. Just like I don't agree with people saying task killers are bad. I guess with the way I use my phone I get different results. I have always noticed better battery life wiping battery stats. Now it could be that the OS will fix battery stats itself over time, but when you ate bouncing around a different rom every two days then the OS doesn't really get a better feel for the battery.
Plus...I came from the evo 4G where we uses trickle charge kernels and I want those back. Never had better battery life than when I had those. Was doing 35+ hours a charge on the stock battery.

Haven't bothered since I never could get the thunderbolt devs to try it. There was "reported" cases with no proof that it caused some batteries to go bad. Even then they were cheap Chinese batteries that 2 people total I think it was claimed went bad.
It was always nice to pull your phone off the charger in the morning at 100% instead of it showing 100% and you pulling it off the charger to say 92%.

Well there is the fact that Li-Ion batteries can not be trickle charged after reaching full charge...
Well they can, but it will hurt the battery. And that isn't me talking from a few bad battery posts... but from knowing how Li-ion batteries work and charge... and reading engineering papers about Li-Ion batteries.
Luckily trickle charging is slow and most people only leave the battery on the charger over night at most. Plus they charge while the device is running and using power. Should someone leave the charger going for 24 hours, with the device off, we would probably be hearing about a fire.
What is probably happening with these trickle charge kernels is:
The phone is going to use some power at all times, the trickle charge is probably just enough to keep the phone running and preventing the battery from draining slowly.
This works because there are two ways to handle full charge status while the charger is still connected.
1) When the battery reaches full charge, the battery is isolated from the device preventing the device from draining the battery. The device then runs solely off the power coming in from the charger. (this method would not benefit from trickle charging, and forcing the battery to continue charging will at best slowly hurt the battery over time, and at worst cause a fire/explosion)
2) When the battery reaches full charge, the charger is isolated from the device. The device runs off the battery until the charge drops to a certain level (usually around 90% or so) before charging starts again.
The second way is how the Rezound does it, and most other devices as well.
The first way requires the ability to switch instantly to the battery from external power without any drop in voltage. This is difficult to do, as a drop in voltage could cause the device to crash/freeze, so many devices do not use this method.

Well if the device was off then the kernel wouldn't be running and trickle charging the battery but when turned on and the battery fully charged they would very slowly charge the battery as it dies. So there should be no risk of the battery catching fire. And anyway, the way the evo trickle charges worked is they would charge your battery to a certain voltage. Once it hit that voltage it would stop charging until it dropped. So it wouldn't be hard to protect the battery.
Did this for 6 months on the evo with no issues.

Any idea why the Xperia S only charges to 95% if you charge it whilst off but is happy to charge 100% when left on to charge.
It charges up to 100% then decharge down to 90% and so up again to 100% and it continues like this, to keep the battery as good as possible over a long time.

I have the same problem. I turned off the phone at 23:00, put to charge, woke up at 07:00, removed from charge and turned on, it was %95. Actually it changes, sometimes %97 sometimes %98. But if i charge it when phone is on it charges to %100 and keep it like that..
On or not the battery will be jumping from ~95% to 100% when left on charge. If you use a battery monitoring app you can see that, even whilst on and charging at 100%, the voltage changes from about 4.2 to 4.1 volts and continually up and down again. This is to increase the battery life because lithium batterys do not like to be kept at 4.2 volts for exessive periods of time.

Battery monitor clearly shows the phone charging to 95% or 100% dependent of its off or on state, there is none of this charging discharging you are on about.

When the phone is on, some battery power is used to maintain the screen backlight and the SoC. Therefore the overall battery consumption is higher, thus the system will charge the battery more, but it will actually stay at the same voltage.

The phone should charge to 100% when switched off and it clearly doesn't, you can give me all the charging mumbo jumbo you like but the handset should be at 100% when turned on but it never even achieves anything past 95%. Once the handset reaches 100% it should revert to a trickle charge not fanny about dipping 5% as is being suggested.

It works this way, whether you like it or not. If you don't, go modify it and enjoy killing your battery.

Yes, but things use to work in an optimized way, not in the way you would like to... Sony prefers to optimize the phone and the battery life than to make people happy by keeping 100% while decreasing drastically battery life...

Right I'll try one more time.
Turned off the phone charges to 95%, no higher and no lower and battery monitor widget can confirm this.
Turned on the phone charges to 100% and remains at 100% without variation until unplugged from the charger and battery monitor can confirm this.
You can see variations in both voltage and current as the charge cycle maintains either the off state 95% charge or the on state 100% charge but in either case the actual level of charge is without fluctuation.
Just picked my phone up from the changer. 99% battery.
I put the phone to charge overnight without turning it off and everyday I wake up at 100%

Not showing 100% even while left ON and charging
Tops out at 95% or 98%, but keeps varying from time to time ..... I have had the phone (XPS) for three days and not seen a 100% charge till now . Also one thing I have noticed is that the Notification light turns from Orange to Green. That's when I normally take the phone off charge.
Mine charges to 100% and stays at 100%.
mine SXS takes 20 minutes from 99 to 100%.

The led turns green at 90%. That's when it slows down charging to protect the battery..

I don't know why my phone can only charge to 99% of battery, this is my second charge already and the first charge also can charge to 99% only
Anyone have same problem ?
Just leave it on the charger. Once it reaches 99% charging reduces to a trickle only. This is by design and not a fault. If you charge overnight you should find it at 100% in the morning .

This is renowned in the official samsung roms of the galaxy series. Do not concern yourself, there is nothing wrong with your phone.
so the best thing to do is to leave it like 1 hour on the charger? I find it annoying to .. If it says fully charged and remove the charger it should be 100% and not 99..
Thank you so much. But when my phone charge reach 100% and i leave it continue charge 2 hours more already and it still show 99% right after i unplug charger.
Don't worry about it at all. There is nothing you can do for it to say 100%. No matter how long you leave it on the charger, once the phone says it's at 100% and you disconnect it will drop to 99%. It isn't a fault, it's what samsung does.
If you want to be really nit picky, you could say that within a second of disconnecting the charger, the phone technically has used some of the battery to stay on, no matter how minimal, so 'technically' with some tiny tiny amount of battery used it is no longer at 100%

Thank you, acttually i came from ONE X, my ONE X take 1 hour to drop from 100% to 99%.
So there are no need to worry about it now. And my S3 battery was great. It can last from morning to night with heavy usage.

Leave your phone on charge, go to CWM wipe the battery then reboot. It should go back to 100% shortly. That's what I did and it worked!
Reason why it really doesn't charge 100% is to protect battery as li-ion batteries should never let completely empty or full as the battery can die.

Mine charged to 100% and never have this problem with my S2
This is frustrating isnt it!
Also has anyone else found that it takes longer to charge than other phones? I.e. my S2?
Im presuming this is due to the bigger capacity battery
battery can only ever be 99.999999999999999999999999999% after you unplug the charger!!!!
not another one....

Mine charges to 100%, dry wiping battery stats. Though to be honest. It drops to 99% the instant I unplug it.
To avoid my OCD, I just disabled the percentage/1% mods. LOL, it makes me too obsessive.
Mine charges to 100% but drops to 99% within 10 minutes. Need to disable percentage display as well asap lol
I have read much about it. It is probably intentional. to save battery or something like that. Do not be so angry about it 99% it the new 100% haha

Battery only charges to about 95% when it is reading 100% anyway. This is for the health of the battery, can't remember the technical details though.
