There seems to be a debate on this topic as to whether you should do a FULL drain on your battery and I wanted to know what people's thoughts were on this in this forum.
I've used my phone twice now to the point where it has auto powered down on it's own. I will then hit the 'Power' button to ensure that battery is truly at 0% (the capacitative buttons blink for a second to confirm that I've hit the power button but there is no more juice left to turn the phone on).
I will plug into the wall charger and allow it to charge for 4 hours (usually around 4 hours, I'll check back to see and hit the power button and the onscreen battery display will show 100% charged).
I will unplug my phone, power on and keep using until the phone fully drains and powers off on it's own again before repeating this cycle.
However, others have stated that this is NOT necessary for Lithium Ion battery and can actually damage the circuitry of the battery? I've always been under the impression that you need to do a complete & full battery drain for lithium ion batteries at least 3 -5 full cycles/times before the battery has been conditioned/optimized for capacity.
Maybe I'm wrong...after all I'm coming from a G1 and this practice helped my atrocious battery life on that dinosaur!
If this is wrong, when should I be plugging my phone back in to charge? When it gives me the first warning to charge in (battery level turns orange - I assume this about 20% battery left) or on the "critical" battery warning when the battery icon in the notification panel turns red (assuming this is about 10% battery left)?
from what I've read in the past, letting your phone drain completely down until it shuts itself off is not good for the battery. I could be wrong but thats what I've read

Yeah, I've heard both sides and I've conditioned my battery for the G1 because it seemed to drain faster if I plugged it into charge when there was 30% or so still left.
Well, I've done two complete cycles so I guess I'll just try recharging when it hits the red mark next time.
When you plug in to charge? Orange, red or whenever to top off?
i plug my phone in when i go to bed. I dont care what the battery is at. I also charge it while i'm at work so when I leave, its around 90-100%. My battery rarely reaches red.

LOL - that would prematurely killed my battery capacity on the G1! I went thru two batteries before I started draining all the way down. Made a difference between 4-6 hours and 6-10 hours.
Seems like this phone doesn't need to do that tho.
But what're you getting on average for battery life and display on time then?

I do the exact same thing. First with my Captivate and now with the SGS2 and the battery life on my captivate held pretty much exactly the same charge for the entire 15 months I used it. The battery on this SGS2 seems to last about 150-175% of the Captivate battery under the same conditions. I just came back from a week on the road where I spent 9-12 hours a day away from a charger and was using my phone constantly all day long and would get back to the hotel room with 30-40% battery left. Considering I was listening to music, playing plants vs zombies and sending and reading push email constantly throughout the day I am very satisfied with the battery life on this phone. I've never done any kind of conditioning or special battery maintenance.

i stopped looking at my battery stats a long time ago. I'll peak in there once in a while but I dont really care what the stats show because I'm always around a charger. As long as I get through 12 hours or so without charging, i'm happy.
Some devices need a full drain cycle to properly calibrate the fuel gauge - ours does NOT.
Lithium ion batteries don't like deep discharging - in fact discharging them too much will permanently damage them (fortunately, all batteries sold to end users have built-in protection chips to prevent overdischarge - but do you REALLY want to rely on that chip?)
Similarly, they don't like charge being forced into them - so don't "bump charge". (Bump charging is removing and immediately reinserting the charger when the phone says charging is complete.)
For long-term storage, store them at around 50% capacity if not being used. LiIons that are stored at 100% charge lose capacity MUCH faster than ones stored at 50%.
A Li-Ion that has been sitting for a long time (months...) will develop a passivation layer that can be detrimental to performance - a few charge/discharge cycles will fix this. You don't need to do a full discharge/recharge - probably even from 90 to 70 and back up a few times should be fine.

what about short charging during the course of the day? For instance, while I'm at work, I like to plug it in for a bit and then use it off the charger. Then before I leave, I charge it again for a bit. Do you think thats okay to charge the phone for short ~1 hour bursts?
No, the battery itself doesn't do well with deep discharges, but every device with one has circuitry to manage this and keep it from happening. The phone will shut off before the battery reaches a critically low discharge state. Just as it will cease charging before it blows up. Just because the phone shuts off does not mean that the battery is too low.
Assuming the phone has the proper cutoffs, it's not really any different to do two discharges to 50% or one to 100%. There have been studies that say leaving it on a charger is bad, doing two 50% cycles is worse than one 100%, etc. I've always just trusted that the phone manufacturers design the battery monitor and control circuits correctly and not worry much about it. And I've never had to replace a battery yet and always get acceptable life.
It's lithium ion, not nickel cadmium.
Full drains are bad for lithium ion.

lithium ion batteries dont like being under 30%. and they also dont do well if they are kept at 80 percent or above all the time. for longest battery life don't just let it sit on the charger all day after it fully charges.
I agree with Mikey here.
Also, batteries take charging current better (less wear) at lower states of charge. That's why I put a variable-current charging algorithm into my Infuse kernels (charginghacks branch on github)
800 mA at low voltages (200 above stock), dropping to 550 near the end (50 below stock).
Unfortunately, charginghacks is likely not going to be possible with our hardware. One of the differences between the I9100 and I777 is a different battery charger circuit - ours is far less flexible.

This phone actually charges with the screen on though, so it's not like the Infuse where the battery would drain with the screen on and the phone charging.

Infuse would charge with the screen on - but not if the screen was on AND the CPU was cranking.
(worst-case was navigation at full brightness - and I've seen reports that the I9100 also has the same problem.)

When web browsing, playing a game, or other general use late at night I'd plug the Infuse into the charger. It would still drain. Doing the same on the SGS II and it at the very least maintains it's battery level, so it's a drastic improvement over the Infuse.
I've had my new HTC Amaze 4G for 4 days now and absolutely love it, what a great phone! The battery life is great (I'm careful with all my settings) and I'm only finding issues with the charging TIME.
It's the second time I've charged it and after noticing how excessively long it took the first time, I clocked it this time and it took 4 hours and 45 minutes. I used a charger that I've used on many other devices with no issues (5 volts 1 amp).
The battery level increases 1% every 3 minutes, which adds up to 5 hours. I calculated this both with the screen on and by averaging out over a longer period of time with the screen off. I also tried with the phone completely off and the results were the same.
I made sure there were no processes hogging up processor time or excessive RAM usage.
When I go into to "Settings -> About Phone -> Battery" Battery status clearly states: Charging (AC).
I have also read somewhere that this can possibly be set this way by design (possibly to prevent the battery from heating or overcharging and saving its life in the long run).
I also realize that the phone is new, and the battery needs a few charges to be settled, but 5 hours to charge on the second charge just seems like too much.
On the HTC product support website, on the faq there is the following question/answer:
How long should it take to charge my battery?
"Your battery can take up to 4 hours to fully charge using the AC charger. It will take much longer using the USB as that is the trickle charge function."
Can anyone out there with an HTC Amaze 4G confirm how long their phone takes to fully charge from the AC charger?
I'm thinking/hoping this is a defective device/battery/setting...I don't like having to wait 5 hours to have my phone fully charged.
Thanks in advance,
Filipe
Ok, I'd like to add one more thing. I finished charging the phone last night (about midnight), by the time I went to bed (around 2 am), after barely having used it, it was still at 100%, now at 9:30 am (7.5 hours later) the battery level is at 95%. I had everything off and very little background services and apps running. Even the network type, is only set to the basic, no data connection was live/standby.When I check the battery status/histogram this is what I get:
-44% went to Cell Standby
-42% to Phone Idle
-8% Display
-6% Wifi (I think I used it before I went to bed, but turned it off right then, and it remained at 100% battery)
I'm not too happy...this can't be right...it shouldn't take 5 hours to charge and discharge this fast? Can anyone shed some light please?
Thanks
Come on....anyone? Please? This is driving me nuts!!
Yeah that sounds about right. Don't complain man. Your battery life is pretty good compared to other devices. My device takes 3 hours to fully charge and can last 24 hours with minor use. Just charge it when you go to bed and you won't notice the time it takes
My desire hd takes almost as much (Around 3 hours) and my Optimus 3d prolly takes even more (5?) to fully charge from a full discharge...
(With Stock HTC/LG Charger. The HTC's AC Adapter is 5V/1A [Shouldn't that charge a battery in under 1 1/2 hrs?]. Not too sure about the LG)
They take Much longer to charge on Computer/Laptop USB Ports. The Optimus 3d actually loses battery while charging (With screen on) with a USB port.
Also, 5% a night is pretty good. My desire hd goes down 3-5% per night (2g, no data enabled.) or 0-1% with Airplane Mode. (Rooted, Revolution 6.31)
And my optimus 3d pretty much runs out of battery in <100 mins with full brightness while Playing Games - It goes down more than 1% per minute depending on the game being played, especially if 3d Converter is used. This is pretty much the same for all GB/Froyo ROMs.

I Agree. Both phones usually last around a day at least for me. You could always try a battery monitor such as GB Battery Stats or watchdog (The CPU One). CPU Intensive applications and Awake time during sleep are usually what cause bad battery life. Faster chargers such as 2A ones should also charge the battery faster, but they might reduce the overall battery life.
I would suggest buying a wall charger and cheap batteries from ebay. They last almost as long as stock batteries and cost only ~$2-4 each. [They apparently explode though. Never happened to me.]
-------------------------------
Both phones seem to charge from 0-90% much faster than 91-100% as well. I'm not sure why, since 100-90 wastes just as fast as 90-0. (Charging from 90%-100% battery practically takes a third of the full charging time)
many thanks
RESOLVED (Sort of...lol)
Thanks for your feedback guys!
I just finished charging it this morning, and it's FASTER NOW!
Took exactly 2 hours and 37 minutes (Battery Moniter is a great app!).
I think it actually may be due to the phone having some sort of smart charging system which "looks after" the battery. Since the phone is new, it might be wanting to start it off with some slowww charges and gradually speed them up.
But I still have to narrow it down some more since this time I'm actually using the supplied cable and charger (the ones I tried before were also 5V/1A).
The cable I was using (had it for a while now) had a pinch or two, it didn't look that bad, but I'm thinking it could also be the cable (could be shorting)!
I'm gonna do some testing on this cable now and report back my findings!
Thanks again!
RESOLVED!!!
Ok, so it actually turned out to be the cable. I really feel like a dumb ass...lol. Oh well, at least I figured it out!
So yeah, one good way to see if your cable / charger is good is to use Battery Monitor, and on the main screen where it says your device is charging (AC) and etc..it will also say the actual amperage (in mA) being fed to the battery...that number should be within the 500 to 750 range, if its lower, there is likely something wrong. (Mine was at 16...lol).
Thank you all for your help!!
Cheers!

My problem was the cable, and it was causing the phone to take five hours to CHARGE, not discharge.
These phones don't hold charge for too long, and the more activity you got going on, the more power it will consume. The screen hogs up the most power, so using the device constantly (especially with high intensity background light) will drain the battery very quick. First smart move would be to set the screen intensity to the lowest setting. Wi-fi and bluetooth, if you're not using them, shut them off. Open your task manager (or get a decent one from the market) and kill all the apps you got running in the background.
Games also require a lot of graphics/processing power, so naturally they will drain a lot of battery too.
Edit: There are some special cases where it could also be related to your network or even simply coverage zones exposed to the device. If it's stuck in a zone where it has weak 4g and 3g signals, it will keep bouncing back and forth causing more drain than normal on the battery as well.
If you've taken all these things into account, then you may have a defective device, then you will want to setup an RMA...or just take it back wherever you bought it and ask to exchange.
Hope this helps,
Cheers
My skyrocket takes about 3.5 hours to charge from 10% to full charge. If I plugged it in the car charger and run google map with the radio on the background, it would slowly drain the battery even though it was plugged in. My iphone 4 did not do this. It charges very fast and does not drain the battery even when I had several apps running in the background. I think the skyrocket consumes more power whether it is plugged in or not.

Hi, what you need is a charger with a higher amperage rating than 500mA (or 0.5A). Buy a charger that is rated for 5V/1Amp like this one and your problems should go away.
The phone is basically "burning" more energy than it is receiving from the USB charger, hence the discharge.
To know the amperage rating of your charger look on the label for numbers that look like "5V/500mA"...
Hope this helps,
Cheers
EDIT: The link I provided does include an iPhone cable, but I'm just referring to the charger itself, the cable would obviously have to be a micro-usb.

thread moved to...mexico?
Most illegal threads are trying to move from Mexico.
But, you need a charging source more powerful then the base 500ma, (or whatever that term of measurement is) computers are only supposed to supply 500ma to a USB port so AC adapters are typically better for charging. But feel free to follow the post above and check the rating on the charger.

Well I bought the Galaxy S3 on the first day of the UK launch and depleted the battery to 0% then charged with the original 1 Amp charger from 0%. I had noticed that this takes a very very long time, around 8 hours. The battery life after charging however is substantial and very adequate.
On the second charge after depletion once again, I decided to use a Griffin 2.1 Amp charger which I had used to charge the hefty Galaxy note with. The Galaxy S3 charges at a much rapid rate and takes around 2-3 hours to reach 100% from 0%. However I have noticed that the battery life depletes a bit faster, Is this due to my imagination or is a 2.1 Amp charger not suitable for this phone as it was with the tablet-like Galaxy note.
Also note that I tried to charge my HTC one X with the 2.1 Amp charger and it charge very slowly, while the original HTC charger has a much lower ampage than 1 Amp
Hmm I have been using my galaxy s charger 0.5amp and it has been charging pretty slowly but seems to deplete faster.
I have been actively using for 50min on wifi now and 85% left. Which seems a bit quick for me. I will try charging with the standard 1amp tonight and see.
Now fast are you depleting at?
I measure my battery life by checking the screen on time just before the death of the charge which was 5 hours on the original charger, with the quick charger its 4 hours. My Galaxy note has no change in battery life weather you any ampere chargers. Also the general battery percentage seems to run low faster anyway on the galaxy s3 using the fast charger.

Just wondering, since the S2 had a limit of 650mA for charging, does this apply to the S3? You guys make it sound like it charges slow as well...
Galaxy s2 does charge very slow for me aswell. Compared to htc phones the Galaxy s 2 charges painfully slowly. Now I regularly use the 2 amp charger on my galaxy s3 and have seen a huge improvement in charging speeds. It charges at around 2% per minute and still lasts around 4 hours of screen time for a full charge.

Thanx for the "shortcode". Where does one find those?
Also from reading about the MHL to HDMI cable from older devices not wotking, it does in fact seem that Samsung have changed the microUSB pinouts (although my Nokia 1.2A charger shows AC in that battery "menu").
Mine charges from about 10% to full in about two and a half hours, using the charger provided in the box.
My s2 came with a 0.7amp charger and took about 2.5 hours. My s3 came with a 1amp charger and takes about the same. Charges to 80% in no time and then slows down for the later part of the charge

A battery isn't like a fuel tank which you simply fill up through the hose until it's full.
Due to physical and chemical reasons, a nearly-full battery takes a lot longer to fill by a certain percent since it simply can't store the energy quickly enough.
Additionally, deep-discharged batteries often start with a slower charging speed (and then cranked up) to keep the battery from dying too soon and/or not being able to reach full capacity.
is the Nokia 1.2A charger ok to use with the samsung G3 as i got one of these spare and would prefer use it if so as the usb is way to short to reach from my desk up and around the back.
but the Nokia 1.2A charger lead is more than long enough
Just to check with all of you, i've been told that it is best not to charge your phone or any other handheld device IF the battery is not at a really low rate, at least not till your device actually prompts you to charge. They were saying that this would cause the battery life to be shortened. But at times, I need to make sure that i have enough battery to last me for a few more hours before i knock off from work, i would just charge the phone (battery at 25-30%) even before it prompts me to. Is it alright to do that often?
2ndly, at times when i stream videos on my phone for many hours, the battery would definitely drain fast and i would need to charge my phone at least 2-3 times a day. Is it alright for me to do that or am i "abusing" it? =X
Appreciate all your advises...Thanks in advance~
so any update on if using the nokia charger is ok with it being 200mah more than the standard 1A charger since it has longer lead.
or there is the 700mah samsung charger from my old S2

I don't know why this misconception still lives on; lithium ion batteries require no priming on first use. The WORST thing you can do with a li-ion battery is to fully deplete it before recharging. It is much better to top it off whenever possible; having said that leaving it turned on, on the charger once it is full is also not the best thing (though nowhere near as bad as depleting it fully).
I believe since this phone has a removable battery with external charger the best thing you can do is always charge your battery in the external charger and just switch out the battery when it gets to around 10%.
Nek0onna you should charge your phone whenever it's not full and you have a handy charger.

Can anybody check what the max charge rate is on this device with a battery monitor app? I have handfuls of 1A and a couple 2.1A chargers. I'd really like to charge at twice the rate if possible but not all devices support such rapid charging (kernel limits and such). Just curious before I buy one Thanks!
Even if Samsung slipped up and allowed a 2A charge i'd never want to try it, because tablet and laptop batteries are rated and manufactured for a higher current charge/discharge and most phone batteries would heat and swell up and possibly explode.
my HP touchpad charges with a 1A charger and it would be nice to use that with my sgs3.
Can anybody please check what the max charge rate is on this device
This is app is a must have and thought I'd share. Like everywhere I have read, they say battery should not be charged to 100%, it will hurt the battery somehow. This app "Battery Charge Limit" automatically (with root) stops charging the phone at whatever percent you want and starts charging back up at whatever percent you want. So you can always stop before it hits 100. It can be used without root but it only notifies you and you have to manually unplug the phone to stop charging. Better with root since its automatic.

Don't charge to 100%
Slow charge only
Don't quick charge
Don't use wireless charger because it heats up the battery
Lower brightness to 10% for best battery life
Disable wifi/lte/nfc/bluetooth for best battery life
...
Enjoy your $1000 phone!

Keep it turned off for a better batter longevity ??
Damn thos people are more preocupied of how to prevent the battery wear than actually enjoying this amazing phone
Well coming from an HTC device where after like what 6 months, my battery starts dying much quicker and hopefully this app and the nature of Samsung makes my phone battery last longer. Never owned a Samsung, so I don't know how the battery lasts over time.
This is a myth, modern phones already prevent damage from overcharging with the charge controller in the phone. Fast charging and slow charging also does not make a difference in battery longevity.
Just use your phone like a phone.
Yeah no
@nukeclears you need to bone up a bit more on battery chemistry before making statements like this. Overcharging is very different from charging to 80%. That's why Apple just implemented a charge limit in ios13 and Tesla strongly recommend charging to 80/90% max for daily use. Samsung just don't want to do this because they haven't felt enough pressure. I'll bet they implement it on the S11 and then for all phones by the end of the year.
Tab S4 has a setting to stop charging at 80%
You guys do need to go through all this? For what?
I have a Note 3 with battery since 2014 or 15, it still gives me the same power, sometimes it's better than it first was.
Charging fast/slow doesn't affect anything, I'm doing so for years.
I really don't think batteries die, if you felt it's weakening, just change OS, not the battery.
Samsung themselves, on the s10 series, suggest to charge from 30% to 80% everytime you need a charge.
In my daily usage, stopping charge to 90% is enough and I have all the juice i need till the next day.
If you are rooted, Battery Charge Limit app can be very useful to optimize the life of your battery (remember: battery is the first hardware component that ages your phone). On my 2015's Sony phone, they wanted me to pay 75 euros for battery replacement...
This thread is full of people who know nothing of batteries.
I bet your phone battery does "feel" the same after years when your os pushed that update that permanently limited your frequencys lmao.

Enjoy replacing it every year because phone batteries are becoming more commonly HARD GLUED into place. So go ahead, switch the whole phone out.
Hello, my Xiamoi Mi 9 is arriving end of next week and I am pretty hyped!
I am really not sure, if I do need these mentioned charging techniques. Apparently you can charge your phone from zero to 100 below one hour. Is it good to charge a phone very often and that fast? Doesn't it heavily influence the battery life? Shouldn't you just use a slow charger and charge it only up to 90%?

Well I don't think the charger influences battery lifespan, it's how you use the device that does
Most phone batteries are lithium ion batteries and honestly chargers (except fake ones) will not harm your battery regardless of charging speed, phones are built to handle them
If you continuously fast charge your battery, it will lower the lifespan of the battery over time. Unless you're planning to keep this phone for more than 4 years, it's not really that big of an issue. But charging speed does affect battery life.
What affects battery life is letting it go to 0% on Lithium. Just make sure you start recharging it around 10%-20% and you will make the battery last for a very long time.
