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

your laptop battery is probably not a lithium-ion battery. Please read said link. Your laptop battery is a NiMH which has the "memory" your talking about. Our cellphones have Lithium-Ion batteries.

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%.

now how do you bump charge a tbolt that when powered off and u plug into a charger boots into recovery instead of staying off?
full instructions r1lover would be awesome bc i want to try "bump charging" but not gonna make my own unplug and plug in instruction since i never have done it before lol.

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
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!
I was wondering if charging the View/Flyer was like charging the HTC phones. You charge til the light turns green, shut it down. Charge until the light turns green, turn it on, charge until light turns green again?
There is no mention of that in the Flyer's user manual.
It just says charge it with the supplied cable and it's fully charged when the light turns solid green.
It sounds like you are maybe talking about calibrating the battery meter? I did the same as my HTC phones. Charge to full, drain to about 20%, repeat a couple times. Don't drain the battery until the device shuts down, its not good for the battery, and no real benefit gained.
I haven't heard of the sequence you mentioned.

No, such myth didn't exists for the Flyer and hopefully they also disappear for other HTC devices.
"Myth? But it works..."
Yes, also my days are lucky when I see a star in my morning coffee grounds
"But why is the percentage then better?"
Ah, the percentage is better. Yes but did you ever check if the device stays longer active? Surely not because then you know, that the accumulator didn't work better when you charge him in a special way. The only change is here cheating the battery statistic which is used to build the percentage. Therefor it stays longer on high values but didn't work any minute longer. Sorry.
.
Li-polimer batteries ALWAYS need a good full initial (out of the box) charge, after that, they improve in discharge over the next 5 to 10 chargings. The battery does not have any charge memory degradation as old Ni-Cads used to have so totally forget the 'discharge-recharge' idea.
However, as posted by redpoint73, never let it get below 15% or life is drastically shortened.
Best policy is, whenever you possibly can, connect it to a HTC (9Volt) charger and keep it topped up.
If you treat you devices battery as a 'only when mobile' power source; then it will give you long life. Don't misuse or abuse it...
I have a charger at the side of my sofa, one in the car (for long work days) and one at the side of the bed for overnight. Done the same for all my HTC devices before, and never had to replace a battery (which BTW, you can do if need with this tab!)
Ok, all that said...Is there such a thing as over charge? If I left the charger plugged in over night, would it be wearing down the battery? So do I need to keep an eye on charging and unplug it as soon as it's full/green lit?

You can leave it plugged in.
It's a fully regulated system, just like a laptop.
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%.

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 wondering it would be okay to remove the Ace's battery and run it on the AC power adapter that charges the battery.
I have read about battery issues here since I got my Ace a few weeks ago. I'm a little disappointed that the charging circuitry isn't smart enough to stop current fed to the battery when the phone signals that it's fully charged. Because of that it's recommended NOT to do what most people probably do... leave their phones connected to the AC charger overnight.
But I haven't been able to find anything on whether or not it would be harmful to pull the battery so it won't overcharge, and run the phone directly from the AC adapter. I didn't realize the phone had such a great radio receiver. I'd love do for long periods of time what I've been doing briefly from time to time on battery... plug it into the audio input for my stereo and play the radio, MP3s, audio from YouTube videos etc.... but powered by household AC.
Anyone know if there'd be any issues doing that?
I tried it , doesn't work unfortunately .
Ace-ing all tests.
Well it was a thought.... Thanks.
My old nokia dumbphone can do that
Btw the phone is smart enough to not overcharge even if u leave it plugged overnight. Its called trickle charge or something, when battery is 100% full it'll stop charging, and when it discharge to 99% it'll charge again till 100% and the cycle continues. Moreover when phone shows 100% charged it was lying all along, to prevent sudden overvoltage. Maybe its just 95% when it showed 100% full

Do you have any links to pages that detail testing that? I googled for quite a while and only came up with a couple hits that said suggested the opposite. But it seems Samsung and the Android OS would be smarter than that.

That sure sounds right. I downloaded an app that displays battery charge by percentage increments. After charging the Ace until it gave an audible notification, within seconds the battery indicator dropped from 100% to I think 87% and stayed there for quite a while.
Well I found a stress test on the Galaxy Ace that says, "The battery contains a microchip that protects it from short circuits and overcharging."
But again I came up with this information saying, "... never put your phone for charging over night as this may hamper the battery’s life very badly..."
There must be definitive info out there on the phone's charging circuity. But I haven't found it yet.
