I have a fairly new S3 galaxy I got as a gift last week. I'm going to army basic training next month, which last about 10 weeks, so I will not be able to use my phone for at least 10 weeks. I was wondering if my S3 battery will be screwed up if I don't use/charge my battery for at least 10 weeks. I tried to do a search, but couldn't find anything. I'm a bad searcher
I remember if you're not going to use a phone for awhile, you should fully discharge the phone before not using it for awhile, but then I hear it's bad for the battery to be drained down to 0%, so that's a bit contradiction.
This isn't a big deal, since I could always buy a spare battery after training, but just curious to know what happens to the battery if not used for a long time period.
Charge the battery at full level and take it out of the cell phone when you leave, thats what i do.
Batteries can get ruined at low levels and at full level out of the phone it will discharge very slowly

This is completely wrong!
If you won't be able to use your phone and you want to preserve your battery in good condition, you should discharge it at level between 40-45% and leave it that way.

I am wondering whether the charging methods make a difference to battery life?
How do you charge your battery, and also your initial charge from new?
This is the first phone I've had that I didn't leave the initial charge on all night 16 hours initial as recommended by most phone manufacturers, and I just took it off after a few hours when it was charged up. Do you think that affects the performance of the battery? I've never charged it for more than a few hours. The main reason I don't leave it on all night is because it gets really hot, so when it goes green light, it's done for me
Do any of you let it run out past the amber warning colour as a completely flat battery is probably better to charge?
All my other phones were left on charge all night, every night, but they weren't this type of phone.... and in truth, it makes no difference whatsoever to the battery. The Motos also needed charging every day
Stunning work guys, 56 views by people I can only assume own the Hero, and nobody wants to divulge their dirty secrets about battery charging... Thanks anyway
Just look around google for Li-ion recharging, there is plenty of resources to read up on when trying to keep battery life at a maximum.

probably because the hero is so new that nobody can tell anything about the battery life? and i don't suppose any of the 56 people has two heros and did the experiment of charging one full and the other for 16 hours, only to use them in the same manner afterwards and count battery life... ?

I was wondering how many people just got the phone, and charged it 16 hours initially or couple of hours and go, and do they leave on all night despite it getting hot.
Not hard...
You should charge it until it is fully charged but not leave it on charge extensively - excess heat may cause the battery life to reduce (although I wouldn't know how much degradation this would cause). It is probably ok every once in a while to leave it on charge overnight, in theory the phone should have circuits to protect against overcharging it anyway. 2 hours is about right for a charge cycle. You should charge it when the phone advises to do so - 15% or less charge. The Lithium Ion battery will only recharge cycle effectively a minimum of 300 times but I would estimate conservatively that is the number of times you can recharge. 2 days between recharges would give you about 2 years life out of a battery. I recharge it every two days, and charge time is about 2 hours.
Yeh, I have to charge it every day though......... Never lasts longer. I just wondered if you were supposed to do the initial first charge overnight and whether it sets the standard for the length of time you get each day after that?
i guess every hero is different. longest i used my phone without charging is 2 days with moderate use.
before i charge my phone i kill all tasks in the background and clear my browser history. might not make a difference but to me it feels better to have a fresh phone after charge.
Is that with the task killer app, or is there another way?
I can't imagine mine ever lasting 2 days.....

when i got the hero the battery was ~half full. i charged it for about half an hour, but had to stop the charging before it was full.
the battery doesn't last longer than one day, although i play a lot with it (obviously). when i put it to the charger i try to let it charge fully up, and i noticed that the charging is stopped when the battery is full (you see the icon in the not.bar go back to normal green battery, and the phone cools down noticably after charging is completed). concerning this i have no problem to leave it plugged in overnight. checked last night, when NOT plugged in it takes 4% of battery for ~7 hours in airplane mode.
Hi this is my first ever post so please bear with me, my lumia like many others suffers from ridiculous battery drain I have the new software and yes I can now charge to the max. However the battery cannot last the day out until I discovered this. Most people I know continually top up there battery, but if you just let it completely die then do a full charge overnight you may like me notice a massive increase in battery life, I have changed nothing about the way I use my phone the only difference is it now lasts 2 days easily.
The figures quoted in battery saver have not changed but as the day goes on the time since last charge goes up but so does the estimated battery life.
My phone is now IMO fantastic.
Maybe if you tried this it might work for you too, do hope so.
One word of caution when the phone has died the phone cannot be switched on until charger has been plugged in for some time, in my case about 20 minutes after plug in the phone switches itself on.
Please try and maybe you will also have the most amazing phone too.

I think I experienced something similar. I then flashed the new firmware and am back to lower battery life. Need to take the time for a few discharge cycles.
The problem with this approach is that some Lumia 800's cannot turn on after a full discharge. People have gone to great lengths to be able to get a tiny bit of charge so that it could power on. Some people have had to send them back for repair.
Question to TS. Do you let it completely die every time now or can you charge it whenever and still get the great battery life?
battery fix maybe
Hi after letting the phone die I have not done it again since, I just top up as needed or at night just as you would normally do.
Hope this helps.
Okey. When you say "completely let it die" do you mean letting it drain and turn off. Or do you start it once again after the first turning off and let it die again?
battery fix maybey
Just use the phone till it turns itself off, then plug in charger, this is when you may have to wait for the phone to switch on, mine turns itself on after about 20 minutes, charge as normal then use as normal, charging as you would normally do.
Good luck.
I did this once intentionally about two weeks ago. Did not notice any difference really. I do not have "bad" battery life to begin with. Not great either though. But it easily lasts a full day with heavy usage which is all I need really.
12 hours since last charge. 73% left on battery. I have used it "normally". About 10 quick calls. A few messages. Browsing on the marketplace installing a few apps editing contacts etc...
I'm pretty heavy on my usage, too. Lots of Mix Radio, sometimes played via bluetooth.
I really enjoyed the S2 guide(somewhere here in xda) about tweaking the phone so as to maximise potential battery time.
With the increased battery of the S3 I know its not as big of a deal but I'd still love to see a few tips on how to go about getting as much juice as possible from the battery on the S3?

I think the first few charge cycles to any battery determine how well they perform, I have put my S3 through 4 full charge cycles so far and the longest life I've had out of it is a smidge over 36 hours with fairly frequent usage, I'm looking in to optimisations for it but I think the charge cycles are key to good long term performance.
Would you mind explaining what a charge cycle is?
Sure..
Basically when I first got the phone I put the battery in and left it charging for ~16-18 hours before I even turned it on, next morning unplugged, turned it on, went through set up etc.. hammered it all day until battery died, went through the same process again (repeated x4 so far, on 5th full charge now)
It is important to charge fully then discharge fully a few times to allow the battery to exercise and calibrate its maximum potential.
After this partial charges are fine, but worth doing a charge/discharge/charge at least once a month to allow the calibration to remain good
Hope that helps,
R.

It's not necessary to charge up the phone before using it the first time I was told. If you drain it first time then proceed as you said afterwards its still basically the same thing imo.
Cool. Thanks for the responses. I'll definitely try one of these methods.

That is not true, a technician told me that newer batteries doest have to be drained and fully charged to perform optimal. It WAS neccesary back in the day with the older devices and no smartphones etc.
It is clearly marked on the directions to charge fully before use
Good day people, I have a dumb question and no need to be polite I know its dumb lol I just got an evo lte and I love it so far. But I did some reading up on training batteries and I'm aware that you can't necessarily train a lithium ion battery but I know there things that you can do help the battery last longer etc.
The first day I did my normal routine, drain it all the way charge it all the way. It took a long time for the battery to die which seemed like it was a good thing. I did that twice and I noticed that after a full charge the battery drops to 97% fairly quickly (like withinless than a min or 2) and from the few days I've had it it seems like it may not hold the charge well over time . I wouldn't normally be concerned about this however this is the first phone I've owned without a removable battery, I don't want to regret it 6 months from now because the phone only lasts 5 hours.
So my question is this I am still within the buyers remorse period should I just exchange it for another onevor am I just being too paranoid? Secondly how do you all train your batteries when you first get the phone? What works for you all who own this phone?
Thanks in advance.

First off, congrats on your choice. This phone has a Li-Ion Polymer battery, which is different from the Li-Ion batteries of yore. I am stock rooted and with medium to heavy use I get a day<12+ hours> out of a full charge with no batt training. I have not experienced the rapid discharge you speak of and if you have no apps causing it, you may need to swap it.
I also get a pretty rapid discharge from 100%->98% - takes about 5 minutes to drop that 2 percent. But after that, I am clear sailing for ~15 hours.
Oh so the rapid discharge thing isn't uncommon then? Hmm

I don't know if it's the same as the og evo and the 3d but when it hit 100% try unplugging it then plug it back in for a few. That may give you the true full charge and stop the quick 2% drop

Yea I'm kind of torn on exchanging it. I may just do it. Of course it would be my luck to get a phone with issues if I did.
That's normal. If this is like the OG Evo (and it probably is), the phone will charge to 100%, then let the battery discharge to 95% before charging back to 100% again. This is primarily to protect the battery and prolong its life. So while the phone may claim to be at 100%, it could be as low as 95% when you unplug from the charger. The rapid discharge you're experiencing is really just the phone adjusting to the actual battery level.
Also, there's no need to "train" the battery. I seem to recall that it's generally not healthy to discharge a Li-Po battery to 0%, and can shorten the life of the battery.
The battery percentage drop you guys are seeing is perfectly normal. No need to exchange your phone. As soon as the kernel source is released by HTC, then the great devs here will be able to bless our phones with some SBC goodness and you will not have that problem anymore
You guys don't think I did any noticeable damage by fully discharching it twice do you? I'm going to charge it and see what happens I don't have any immediate thoughts of exchanging it based off of what you guys are saying. I'm going to charge it up and post results. If its not like what you guys are getting life wise I may exchange it as I still have like 5 days left.
Minor update 7 hours 27 minutes 52% left.

No, it's fine.
Fully discharging it just reduces the number of cycles left you have. Most li-ion batteries have 1000 charge cycles. Battery charge is not an exact science. Do not look at it like you are not getting the full charge.
So at the end of the day it looks like roughly 8 to 9 hours of moderate to heavy use on my phone moderate for the first 7 hours heavy for the last 2 and some change. Does that sound about right?

I was told many years ago to fully drain and then fully charge a rechargeable battery or else it would shorten its life span. Is this really true?
Currently, if my battery is at 30% when I go to bed I leave it alone and charge it the next morning when I get to work after it drops to 5% or less and just deal with not having my phone for a few hours during the work day. I would love to charge my phone each night and always have my phone usable throughout the day.
My concern is that if I charge my battery each nigh I will kill the battery before I can get a new phone.
What us the truth?!
There's a lot of confusion on proper battery charging techniques. Lots of people are stuck on the old ways of thinking, where you should let the battery completely die before recharging it or else the battery will get a "memory" and won't last as long. I won't pretend to be an expert on the topic, so hopefully someone else can chime in, but from my understanding you do NOT want to let newer style batteries die before recharging them as it shortens their lifespan.
That used to be true, but doesn't apply to the batteries used in phones today. You can recharge whenever you'd like, but you may need to 'calibrate' your phone from time to time to properly recognize an entire battery cycle.
Recently, my Droid Razr Maxx drained completely, and will no longer take a charge; very frustrating considering it's less than 2 months old! That's the problem with a non-removable battery. Very expensive paperweight.
