Thanks for everybody's input. I think I've got our down now Lol. But I'd like to keep the discussion open for anyone that would like to be better informed.
New topic: Tips & Tricks for getting the most out of your battery.
Thanks guys!
Don't run it dead regularly (that was for ni batteries), don't charge it all the time (ie topping off everytime you're near a charger). If going to store powered down for long periods do so at like %60 capacity.

Just to clarify, you saying to not charge when battery it has more than 60% charge remaining? If yes. Then how low do you recommend as to minimum charge left on battery when you plug it in?

It's been a while since I have actually cared about a phone enough to really want to take care of every part of it, including the battery, and I was wondering what the best way to keep it fresh is?
Use until it dies and fully charge every time.
Use until low power warning and recharge.
idk what other methods there are....
Anyway, appreciate any and all tips guys:good:

Best way is to not worry about it. Only thing you want to avoid is letting it die in standby over and over.

Sorry I was so brief was at work on lunch.
In the ideal world you'd probably charge around %20-%30. Lithium batteries do not like being over drained or overcharged. Overcharging isn't really an issue since our phone handles charging. Over draining repeatedly will drain max capacity, same with overcharging. The %60 i refer to is a rough number if you were going to be storing the phone powered off for weeks or months, lithium batteries should not be stored at max voltage or drained.
You don't want to be constantly "topping" your battery off either. The life of a lithium battery is generally going to be measured in charge cycles. So charging it every time you're sitting at a charger will really just wear it out faster.
I generally just charge my phone every night when i go to bed. With as long as these phones last on a charge; I've yet to burn through my entire battery in less than a day more than a time or two. Don't put too much thought into it or worry too terribly much. Running it down once or twice isn't going to do much that you'd immediately notice, but doing it every time is certainly not a good idea!

Okay. Thanks for all the info. It really helps to know that stuff. I'm not to worried about burning through charge cycles. I'm getting 2-3 days of a charge. 4 if I drain it. Battery on this is the best I have even seen. Truly incredible. I don't know how they managed it. But I am absolutely loving it.

The only thing you need to worry about is not letting your battery reach below 14%. Unless your out or not near a charger it's understandable.
Charge your phone once it hits 14%. Let it fully charge don't interrupt it (unless you have too)
Sometimes don't charge your device to 100% I sometimes charge mines to 90%.
Let the battery die once or twice a month.
Just don't worry about the battery. By time you hit anywhere near 500 charge cycles you'll be on the m9 or a new device.

Because you wanna train your battery and get the most out of it. A lot of people say those are old rules because these batteries don't have memory cells. But you'll find yourself not needing to replace the battery as fast as you would by just letting it die all the time
I have replaced a cell phone battery yet and I've been using that method since flip phones days

Hhrrmmm. i think you're thinking of nickel based batteries (nicd, nimh, etc). Generally lithium cells really dont like low voltages or have memory.

I think he's correct on the letting it die once every month or so. I did a lot of research on this a while back and ideally you don't let your phone drop below 50% regularly and don't let it sit on the charger all night since its going to be at 100% for many hours before you wake up a li ion batteries prefer to not be at 100%. The discharging it fully will calibrate it and make sure all the cells are being used since if certain cells don't get discharged every so often they start to lose ability to hold a charge. Keep in mind I looked all this up 2 years ago and most of the issues only affect people who keep phones for 2+ years unless the do 100%-0% every day then their battery won't last long.
http://batteryuniversity.com/learn/article/do_and_dont_battery_table
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
These phones all have battery protection circuitry built into them.
As the battery approaches 100% charge the charge current reduces to almost nothing to prevent overcharging.
Having said this I would not leave the phone on charge for weeks on end but there is really no reason to worry about taking it off charge the moment it shows 100%.
Likewise for discharge. When the phone indicates that the battery is getting flat it will make sure that even if you run the phone till it dies, the battery will not have been allowed to overdischarge. When your phone switches off software is telling the phone to power down to protect the battery.
Also, to touch upon Lithium battery charge cycles, one charge cycle is the 100% charging of the battery, now keep in mind this can be from 0-100% OR it can also be the sum of multiple chargings up to 100% capacity of the battery
I.e.- charging from 75% to 100% once is not considered a charge cycle to the battery, but do it three more times from 75% (25%x4=100%"rated" capacity) and it considers THAT one charge cycle. So if you charge from 50% regularly, two times charging from 50 to 100% is ONE charging cycle.

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.

But isn't flattening Lithium Ion batteries bad for them? If you search the internet it often says not to over discharge as well as under charging them also increasing their life span. The older NiMh and NiCd batteries benefited from full discharge and recharge.

If there's one way to send your battery to an early grave, this is it.
Modern batteries are limited by their number of discharge/recharge cycles. Letting the battery drop to 80% and then recharging is the same as letting it drop to 20%.
However, allowing the capacity to drop to zero is a stupid thing to do, since this permanently damages the battery. The battery has its own controller which goes some way towards protecting it, but it's a trade-off between shortening the lifetime and the actually runtime you can get from the battery.
So, to summarise: you're fine letting the battery drop to 10-20% before recharging. Do not allow it to fall below this too often, as you'll shorten the lifespan.

Yes it is 'bad' for Li-on batteries to be run down to zero. Ignore any posts you see saying otherwise.
Just charge it and use it. When possible, top up charge. Li-on batteries do not have memories and do not need to be 'conditioned'.

Hmm, my bad, my Apologies, seems there's some way to go yet for me, I assumed this was the case as I had horrid life out straight out of the box, these discharge cycles helped tremendously, though with that being said I tend to not leave it below 15% now before I charge.
Oh well, live and learn.
Never discharge the battery to less then 10-15% if possible.
Aww crap I discharged it to zero last night. I thought out make sense cause back when I used the nexus one, there was this method of conditioning battery by discharging the battery. Ah well thanks guys

Won't hurt that much. Contrary to what people say li-ion has limit on amount of recharge applied from whatever level it was applied. Also the phone cuts off before dangerous low levels are reached. However frequently doing this should be avoided.
The biggest danger is leaving phone in discharged state for long period of time as the background discharge (e.g. Power on off button, clock, etc.) will flatten the battery, without the protection circuits and completely ruin it; charging while hot (above 50 to 60 c) will also send battery to an early grave.

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. :/

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

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...
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.

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
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?

I should've probably put this in the Q and A area sorry
Sent from my HTC_Amaze_4G using xda premium
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.
