What is the proper way ? I've looked online and people say differently. People say let your battery drop to 15 percent or a little under then fully charge. Then others say let the battery completely run out until the battery dies then fully charge it, but I heard letting the battery completely is bad and not necessary. So what exactly do people when when they say fully discharge or battery manufactures when then say fully discharge a brand new battery then charge?

Down to atleast 3%. That's how I've done it for years. Every opinion differs though
I always charge my phone when I know I will need a full charge, I never really cared about the battery percentage too much, but I do agree that there is no real wrong way.
It's my understanding that in order to properly calibrate a battery you must completely drain it.
From what I've gathered the battery needs to know what a "full charge" is and the only way to get a full charge is to be completely empty.
So following instructions from threads back on the MT4G forums I calibrate my battery by:
1. Letting it completely die.
2. Turning it back on just to make sure it dies again. And I do this til it won't turn on again.
3. Then charging it, while off, til it has a green light.
4. Then I unplug it, turn it on, turn it off and plug it back in til green.
Whether this really really makes a difference or not...well I can't say for sure
but my battery lasts longer than my sister's Amaze.
Hope that helps.

same with me, I never bother with letting it drain fully, I did with my first phone, and a few months after I got it the battery was pooched, so from then on I never cared. plus with the cost of getting a replacement, or even aftermarket batteries like anker, not following procedure to drain then charge a battery is a no brainer for me.
But, if I did care, then I'd drain it fully, then charge it back up. the percentages on my phone aren't accurate anyway. Actually today I was playing blade master and I kept getting the battery warning, and it was pretty steady from 20 down to 5, then hung there for a while, maybe an extra 15-20 mins, then died. so percentages are approximate. a full drain and then full charge should do.
What the other guy listed in steps is correct, though I'll give you a heads up, the amaze battery is total ***** when it dies completely, so be prepared to have it plugged in alllllllll night for it to charge.
Just got my self a replacement, the battery ended up dying, took me four hours to move 8%, was about to go buy a replacement the next day, but I let it charge overnight, it's been remarkable since then.

Lol my bad bro, I was just too lazy to scroll up to look for your name.
So, if you would care about calibrating, do you let it die and fully charge every time you flash a ROM? Or just the very first time when it's new?
Seems every battery is different. I let mine die completely and then charge overnight, but had the green light after an hour and half. I let it stay on though overnight.
I personally didn't see a drastic difference.
A lot of folks day to wipe your battery stats as that helps. I have yet to try that.
Just kinda deal with the 8-12 hours I get on ICS. I used to get 12-16 with gingerbread.

Wiping battery stats doesn't help, IMO, for the number of times I've tested it on a few devices. My results so far just shows that wiping it just fools the device to stay full longer than it should but after the battery passes the 90% physically it starts making rapid drops until it stabilizes somewhere around 50%.
Right now I'm letting the battery die. This is the life on 4g and listening to pandora lol wow. What awesome battery life this is with the brightness at 25 percent and a 2000 mah battery heh.

So i am a recent convert coming from a RAZR and would like to know whats the best way to train the battery. The RAZR was horrible.
What do you mean train it?
I think he means as far as calibrate it from the beginning. Usually when I take a phone outta the box ill let the battery dir from there. No immediate charge. And then ill charge it and let it completely die 3 times. Done that with all my devices in the past few years and usually works like a charm. But when root comes we can add battery tweaks and such. My battery right now isn't too bad, but my EVO 3D was a lil better. I love this frkken phone

The app battery calibration from the market works well too
I have noticed that when looking in the battery usage monitor it seems that the battery hits full charge then drops to 96% and hits full charge again about ten times a night. Kind of bizarre, and probably contributing to the battery life being shorter. Also noticed that the 2750mah battery is read as 2720mah on multiple extended batteries.

After flashing a Rom you have to calibrate battery by letting it drain fully and then fully recharge so can't be that hurtful. Now letting it sit at 0% for 5 hours is not such a good idea.

Do most of you guys keep your phones plugged in (charging) as long as you are around a USB port/wall outlet or not? Unless I buy a battery booster, I don't like the thought of my phone being any less than topped off in the event that I can't charge it for a while. I'm aware that the battery can't be over-charged, but keeping it at 100% so much of the time doesn't seem like a good way to treat it. :/
Won't hurt it , people in the office have been doing it forever.

Everything you do with your phone stresses your battery.
Point being... As reverepats said... For the first few charges its good to drain it down then full charge it back up. Your not hurting the battery in such a way its going to noticeably shorten the life span.
This by the way doesnt do much for the battery itself... More for the OS. The OS compiles statics on usage, etc... This helps the OS "learn" the battery.
Now to counter point I made above...
The OS will also learn the battery over time... By doing cycle charges you are only speeding it up some. I still recommend cycle charging. I try to do it about once a week.
The best way to train/calibrate the battery in my opinion is to charge it till the green notification light comes on with the phone on. Then unplug the charger from the phone and then turn off the phone. Once it is completely off plug it back into the charger and charge it until the green notification light comes on. Then unplug the charger from the phone and then turn on the phone. Once the phone is done booting up and everything is loaded and what not then charge it till the green notification light comes on and then unplug it and you have now successfully trained/calibrated your battery.
I did this with my Rezound when I first got it and when I got my extended battery and the phone lasts me 24-36 hours with moderate use and Juice Defender installed. I hope this helps

But, but, that requires me to leave this beautiful phone turned off for a while, I'm not sure I can survive that torture...
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.
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
Are we going to need to charge this phone for 8-10 prior to first use?

They always say to do that, but I have never been able to keep hands off a new phone that long.

Usually they come about half charged so you'll be good for a few hours. The 8-10 hour rule was for older battery technology (nickel cadmium), the new kind (lithium polymer I think?) is much more flexible as far as charging schedules. I don't think you have to do anything special for the initial charge.

The better question is can you wait that long?

Honestly, when you get your phone (and once a month) you should let your battery drain completely (within 2% is a decent rule) and then charge all the way. Do this for 2-3 cycles and you battery will last a lot longer. This is true for any electronics.

not quite - the below is from Battery University in regards to lithium ion batteries (which is what's in the evo);
If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery.

And
Lithium-ion is a very clean system and does not need formatting when new, nor does it require the level of maintenance that nickel-based batteries do. The first charge is no different than the fifth or the 50th. Formatting makes little difference because the maximum capacity is available right from the beginning. Nor does a full discharge improve the capacity once faded. In most cases, a low capacity signals the end of life. A discharge/charge may be beneficial for calibrating a “smart” battery, but this service only addresses the digital part of the pack and does nothing to improve the electrochemical battery. Instructions to charge a new battery for eight hours are seen as “old school” from the nickel battery days.

Lithium Polymer batteries are not the same as Lithium Ion batteries.
Avoid draining them to the point the phone shuts off. If they get too low they die.
Never run them down on purpose.
I run RC trucks, I have been using LiPo batteries for several years.

If the phone's charge time is roughly 2-4 hours, what will charging it 8-10 accomplish?
The Sprint store opens and activates phones on the spot regardless of charge, which leads me to believe that--while some/most Sprint store Employees aren't very knowledgeable in electronics, I'm sure they would have been told in one of the many meetings they have that you need to not do this and inform the customer of needing to charge their phone for __ amount of time before using it.
At any rate I'm just playing along with the possibility. Of course you don't need to charge your phone any amount of time before using it the first time. Our battery technology has evolved to the point where trying to keep track of charge schedules is irrelevant and not needed. Seriously, if it were, they would have provided a small paper calendar with your phone so that you can mark when the last time you fully discharged it as well as instructions on how to care for your battery.

While this is accurate, I still always try to full discharge as often as possible. I do this because the phone reads battery information and calibrates the battery percentage based on that.
In my own unscientific research, it seems that frequent charging messes up the battery readings. I know that there was once an article about wiping battery stats being a placebo effect, but it really does seem to help when you wipe, full charge, full discharge. The phone always seems to last longer, but its likely because the phone is properly calibrating the max/min capacity of the battery accurately.

The batteries in phones anymore do not use memory in the actual cell. The phone itself does keep record of the battery to help protect it, and clearing that out and re-calibrating the battery by draining it can help, but doing full drains to the battery will just reduce the overall life span of the battery.

The batteries in phones are not lipos.. they are lithium ion... Putting a lipo in a phone is just asking for death or injury lol..
When the first EVO came out this method was dine to train the phone more then the battery and I still use it.. drain till it turns off.. turn back on..keep doing this till it will not turn on..full charge it.. take off charger and put back on till led is green again. I've never burnt out a battery but I can't professional it helped battery life but as I said when EVO first came out battery life was horrid

The LG Fusic had a LiPo battery.
Yeah i bet some phones will have no charge after customs played with them for a while and did not turn them off and put them back in for us to get screwed. But you may have a update already apply as well to the phone.

If I recall correctly, only a sample from each batch was tested and that tested sample was not shipped out to customers.
Yup thats what I heard as well
What I read says this phone has a LiPo battery. They are being used more often in portable electronics than you think.

simple solution.
keep the phone plugged in while you use it. duh.
charge at the wall and your office computer
Hey guys I'm on the DNA and just having this issue that's bothering me. Before I use to be able to get the phone to 1 percent and then charge not a big deal I like to get it between 1-5 percent before charging now it dies prematurely around 6 percent and just makes me think something is being read wrong. I've wiped that battery stats already and some cycles but same issue. Any suggestions? Could my battery be going bad?

One way a battery will show you it is bad (works on all batteries that aren't round in design) is it will have a slight bulge. In other words it will not be completely flat anymore.
When a battery goes bad, it's cell(s) will swell. I have had my fair share of phone batteries go bad.
Usually another way to see if a battery is going bad is it will lose % rather quickly. I had one that would go from 70% to 20% in seconds.
From what you said is your habit (using it down to 1% every time before charging it) leads me to believe it may be starting to go bad, as most lithium based batteries don't handle full drains that well. (It drastically shortens their life).
TL/DR? Check to see if your battery has a bulge, see if it drops or gains % really quickly, and try not to drain it to completely dead all the time.

Mine did that too after having it for about 10 months... I think it is just the beginning signs of the battery starting to wear out (I assume it will get worse as more charge cycles happen) which is normal for all batteries... I had to get a new dna (I broke my charging port) and the new one has no problems anymore.

Full discharges is a fantastic way to drastically shorten the life of your battery. While I have never let it go below 10% and cannot tell you if my phone would do the same thing... I'd suggest that you stop letting yours get low enough that you experience this anyway.
