Battery charging - HTC EVO 3D

Anyone. Each else noticed that the battery charges strange..
With battery monitor the monitor is all over the place up and down
I know this is a bigger battery.. But did they sprint or htc change how the phone charges?
E3D

Mine doesn't exactly do that, but I swear I have yet to see mine say 100%. It stays at 99 forever and then the light just turns green.

That's how you keep a battery properly charged. You top it off every so often. You will overcharged the battery if you keep pumping it while its at 100%. So you hit 99-100 let it drop to 97-98, rinse and repeat.
Can I get a ROOT canal for my 3vo cavity?

No.
Li-Ion batteries and the chargers have a cut off built in that automatically do this to prevent overcharge.

I'll post a screen shot later if i can.. What application allows it with out root.

if i had it lol

It's fine, once your phone is at 100% it'll let itself discharge till it is at 95%, and then it will charge back to 100%. It'll keep doing this till it is removed from the charger. Harmless is to say.
Someone already stated the answer in here.

Yeah, something is different though. This morning my phone was plugged in and everything and it hadn't hit the green light yet but just stopped charging. The battery icon didnt show that it was charging like it should while plugged in either. Plugged it in and it eventually started again.

well, my first evo3d woudlnt hit 100 and i let it charge immediatly.
my 2nd evo3d was used right away.. i let it drop to 5% then charged it to 100%.. this time, it actually showed 100% .. now the battery sips down by 1% at a time. feels good.. only problem now is that i have a different screen vs my first 3d.. the whites arent as bright.. feels like the whole damn epson vs novatec again.. grrr

There seems to be some logic in the battery charging algorithm that reduces the draw from the charger when it gets close to 100%. Using battery monitor widget, I can see that it charges at 900ma or so when just plugged in but this drops to a mere 30ma when it's at 99%. That's why it takes forever to get to 100%.

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

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.

I don't know if they did anything differently, but I definitely don't notice the typical 100-90 drop (or avalanche) like with the EVO.
Simple answer, of course its the same.
long answer..not answering, haha
Of course battery stops charging at 100%. Its full. What do you want it to goto 101%
Sent from my Nexus S 4G using XDA App
You guys know what he means... geeez. the Evo would read 100% when it would actually be anywhere from 90-100% (before the awesome SBC kernels)
I would also like to know how the charging cycles work on the 3D, I would hope it is different.
its not actually going to charge to 100%, these battery's don't do that, hurts the life of the battery.
what does the phone actually say? Can't say I know, but it doesn't really matter what it say's, its still functionally the same.
I guess ill have to test this out and see
Sent from my PG86100 using XDA App
without the battery widget the bar can show at 100% and still be charging till the light turns green.
the battery bar in settings changes too 100% when it reaches 91%
99%-100% takes the longest for the device to register.
The E3D takes longer to charge than my evo with the extended battery
OK. My battery just charged to 100% and I went into battery widget app and it shows that the phone is no longer charging and turns off just like the EVO and starts to discharge...
Sent from my PG86100 using XDA App
ok after a few days i've noticed that the green indicator light comes on when its fully charged. when i power it down to charge i cant seem to get it to turn green... has anyone else experienced this?
Let me see if I can shed some light on this.
When I plug my EVO 3D in, it'll go up to 100% and the red light will turn to green. If I leave it on my charger and check on it a bit later, I notice that the battery % will go down to about 95% and then it'll go back up to 100%.
So from my initial observations, it looks like the kernel is very similar to the EVO 4G's SBC kernels. It's quite possible that it is SBC but I guess we won't be able to completely figure it out until HTC releases the kernel source code.
My .02. Hope this sheds some light for others of you to pay attention to

This how li-ion batteries are supposed to be charged, sbc kernels prevented it from ever turning the charger off so it kept feeding the battery power after it was at 100%
Sent from my PG86100 using XDA Premium App
Not like sbc, its like the bump charging method.
Og evo went down to 90 then back to 100, so if it only goes down to 95 thats better at least. Sure its not "100" percent of all the battery life... but its 100% of the advertised battery life.
Definitely noticed that it doesn't have that significant drop from overcharging. The battery will stop charging at 100%, discharge, and top off as needed. Much better than what we saw on the Evo.
had battery at 1% , plugged it in , 6 hours later it was at 73%... that normal?

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

[Guide][Bump-Charge] A Way To Sip More Power

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.

Stupid phones! Just give us a bad ass device that's unlocked, so we can do what we want already! The majority of people with these devices have no clue of their potential anyway. I work for vzw Btw and just deleted all my pics of the Samsung "Fixthis" over rated and cheap feeling like all other Sammy's IMO. I'm keeping my rezound no matter what.

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

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?

What/where is this 1% indicator?

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.

[Q] Battery charging question?

I've only had my 3d for a few days but since day one it has taken forever for my battery to charge to a 100% . It will charge to 99% and stay there for what seems like an hour then when it finally hits a 100% it will start to discharge after about 5 minutes.
My question is, is this normal?
TIA for any help.
HTC handles charging differently than others. That is normal, don't worry about it. It will discharge a few percent and then top itself off again

I know about the discharge but its the fact that it takes so long to hit a 100% from 99% .
But thanks for the reply I know you have to be busy with all your development.

Mine does that weird part about it is when it dead dead and you throw it on the charger for 9hrs it still won't turn green lol.. I may have to let it sit there longer ... When I turn it on says 99% and still charging will hit 100% pretty quick and battery life lasts forever lol... It is normal tho for it to take awhile to hit 100 % and that discharge thing is normal too no worrys man..
Yeah, I guess it's HTC 'method' to charge the battery, although it makes no sense... I thought maybe it was something to do with the stock battery, so I bought 'Platinum' series 1900mAh the other day and it still does the same things....
Not only taking an hour or so to go from 99 to 100 percent, but when I try to 'calibrate' the battery, it takes an additional 5 or 6 hours it seems. I charge it to 100, turn it off, plug it back in, and wait for the green light to come on again.... two or three hours later, it will finally turn green. If I only let it charge for an hour or so and turn it on, the battery will show 95%... absolutely ridiculous. I don't ever remember the Evo being like that. The battery charging on the 3D is just stupid, in my opinion
