Issue with battery? 99% for 20+ minutes? - HTC Droid DNA

I'm trying to charge my battery to 100% and it's been sitting at 99% for a good while now. My battery life has been pretty abysmal and I've been trying to figure out if it's the apps I have installed or if it's the actual batter on the phone.
Does anyone know a lot about batteries? Is this normal? Does this mean I should seek a replacement?
So, 99% charge on the 5v/1a charger for a good 20 minutes now, still at 99%.
Phone will die in 6-8 hours.
Sometimes phone shuts off when still reading 4% battery left.
What's the prognosis docs?

Charging from 99% to 100% usually takes a while but even more so on HTC phones. Just give it a while until it shows 100% and the led light turns green.

It's been an hour lol.

Unplug it then plug it back in, it will jump to 100%.

it does that really slow because it's at a trickle charge above like 95%. so it's not pulling at 1amp anymore, and it slowly hits 100. it's a safety measure so that it doesn't stay at 100% all the time

Yeah, that happens on all phones. It shouldn't take an hour, though. Try what orangechoochoo said, just unplug it and plug it back in.
I know on my ipod and on my friends' iphones, if you unplug it while it's in the 99%-~100% zone it'll drop down to like 90% since it's not "really" charged. I think sometimes the battery % while charging is just a little optimistic.

it might not actually be sitting at 99, unless you've actually just been watching the percentage for the full hour. i've seen on other phones that it will go back and forth bw 99 and 100 once it hits a certain point

Plugged in all day or no?

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.

Does your 3D's battery achieved 100% Charging??? Mine Hasn't!!

For some reason my 3D's battery never achieves 100% charge. I leave it charging using the HTC charger included and I never get more than 98% charge after 12 hours.
Anyone else have this problem??

Mine does, but it takes a while. Normally it charges up pretty fast up to like 95. Then it slows down and once it gets to 99, it stays there for atleast 10 mins and finally goes to 100. One thing I did notice though is when it gets to 100, even if its on the charger it will start falling back to 99 and 98.
Mine has never reached 100%, even if I unplug it when the light turns green and plug it back in it will just stay at 99%.
I've woken up to 97 or 98, it has never gone above that.
I believe HTC has some sort of smart charger system on here. It will charge quickly to ~ 95, then slow down until it hits 100. Then it will quit charging at all until it drops back down to ~95 or so and repeat the process. Supposedly, it will increase battery life by not overcharging it.

3vo. That is all that needs be said.
The Evo 3D always chargers too 100% what you are seeing is that once the device hits 100% it stops charging and waits till the battery drops to 90% or so before it starts charging again, so what does that mean you're catching the battery after it has stop charging and is recharging again

He is right....on the OG EVO its would display 100 while it was dropping but the 3vo shows the actual percentage
Once the led turns green unplug restart and plug back in. Should now show the led red again and finish charging. After once it should be fine.

I am using an aftermarket stand alone battery charger. When I took it off the charger this morning it only shows at 91%. Does anybody have any idea why that would be the case? I have used this same kind of a setup with my Evo and it was always at 100% when I pulled the battery off the charger. I was even using extended batteries and never had a problem!

Probably some kind of safeguard chip built into the battery that does this even on aftermarket wall chargers. I have never seen this before and every aftermarket charger I have had has charged the batteries to 100% and they stayed there, but maybe HTC got hip to the aftermarket chargers and implemented the battery mod to work on them too. Just a guess and there is no proven fact to this statement.
Run it down, then charge it up
My 3D wouldn't charge to 100% until I ran it until it shut down due to low battery and charged it until the green light like 3 times. Once I hit that magical 3rd time, it showed 100%.
at first it was only orange light , but after unplugging then plugging back in I get green light.
you can get a 100% charger like others have said, but for sure the charging software makes it tricky

Thanks man. I thought I was going crazy, b/c I wake up every morning to about 96% charge after about 8hrs on the charger. Totally makes sense now. (pun intended )
Every wall hub charger I get from ebay has helped charge all my HTC and Nexus S phones better. I always get 100%, and they stay there not draining to 90% in under 5 mins like the wall plug does.
I abhor the wall plug and have avoided it like the plague..not only that, but micro USB breaks very easily and is not a sturdy charging port.
I see them break on every modern model phone today. It's just a horrible unsturdy design. Wish we'd go back to mini usb.

That is the problem. Every one that I have ever used also charged and kept them at 100%. This battery did not. It came off the charger after a full day of being fully charged and it was at 91%
I have seen mine go to 100% once. They must have done something new here with either how it charges, or how it computes the percentage remaining, since this is the first HTC phone I have had (I've had them since the Palm Treos) that doesn't go from 100% to 90% in the first 10 mins of use.
Perhaps HTC has implemented an SBC-like charging system on the E3D

I think it might be something else. The battery does not show 100% even off of the stand alone charger!

Battery only charges to 99%

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."

Problems charging battery to 100%

Is anybody having problems fully charging the battery to100 percent? I noticed the battery life has gotten worse since I owned the phone. it would always charge 100 percent. Now it only charges to about 98 percent. I made sure all active apps are turned off and running apps as well turned off. I will turn my phone off at least once a week and fully charge it overnight. I notice after doing this the battery life Is always worse.

The phones charges to 100% and then it stops charging if left on the charger. So you will lose 2% or 3% of battery power before it start charging again. This is designed to help keep the battery healthy as its usually not a good idea to leave the phone charging for long periods of time.
I charge mine until the thing on the status bars pops up indicating "full" and then remove from charger. The "full" indicator pops up about a half hour after the phone shows 100% which I find odd however... That also might be a battery health thing as they probably don't want you to charge it to absolute max, so maybe by saying 100% whens its more like 97% that it helps with battery health...

It trickle charges for a while after hitting 100%, then shuts off giving you the "unplug me" notification, drains a few %, then back to trickle charging.
In the morning if you unplug it and then plug it back in it will be fully charged in less than 30 minutes. To the full 100%.
When I first got my phone I was playing with it so much (and testing out the true battery capacity) I was often plugging it in at night with a nearly dead battery - which takes longer to fully charge overnight. So by morning it had only stopped charging an hour or two earlier so it still showed 100% for a while. Lately its been at 60-70% so by morning it has been done for 4-5 hours. So after booting it often shows 98%. No difference in battery capacity, just a longer time post-charge where it has drained a percent or two.

Try the unplug-then-replug routine one morning to restart the charging process. See if it is better that day. If it is, you are probably running into the same problem I talked about in my last paragraph.

95% Charge

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.

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%

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%.

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.

Under UK generic .75 the phone charges all the way to 100% while off now

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