[Q] Best battery charging practices? - Galaxy Note II Q&A, Help & Troubleshooting

Hello all,
I hope I'm not beating a dead horse by asking this because I have searched this site as well as other places around the internet and there seems to be alot of information out there concerning how to charge your phone battery. But every time I read something, it seems to contradict the last thing I read. So I wanted to pose both viewpoints to the experts here in one place and hopefully get some clarification.
I recently got the Note 2 and am really happy with the phone. One of the biggest and most welcome surprises is the terrific battery life I have gotten so far. I am coming from a HTC Sensation and while I liked that phone, I always felt like the battery life pretty much sucked. When I first got the phone, it would barley get me through the waking hours of the day and that was only if I used it sparingly. Over the course of the nearly two years I had it, the battery life just got worse. I typically would leave my phone charging all night as well as in the car during the day if I had heavier use that day.
With the Note 2, I am seeing much better performance. I can easily make it through a whole day starting at 6am and by the time night comes still have over 50% charge remaining. I am not a heavy user but I have found myself using it more, trying to deplete the battery so I can charge it at night. My problem now is I can make it through one day with no problem but to make it through two full days may not work as well. I feel if I don't charge at night when its still around 50-45%, the next day I may need to charge right in the middle of the day when I need to use it or am not by a charger.
So my question is what is the best practice? Is it best to fully charge then fully discharge, and if so does it need to be a regular habit or just the first few cycles? Do I need to remove the phone from the charger once its fully charged or will an overnight charge be a safe option? If the phone is only at 40% or more is it ok to charge it? Are there any other battery management practices I should be aware of?
Thanks in advance for your help

dont read too much into battery charges...charge as you like...........at home, in car, connected to pc...........lol..........the battery will last for 2-3 yrs well...then if you feel it is dying, it has a removable battery.........you can always change the battery, buy a new one...they are cheap...
for ex:
you get ~1200 cycles if you charge from 40%-90%, but you will charge twice a day (2 charges a day will last ~400 days)
you get ~400 cycles if you charge from 10%-100%..charging 1 time a day will last ~400 days again

The above is the only proven effect on our batteries. The rest is handled by the battery itself.

Honestly ive always charged my phones however and whenever I liked. Overnight and at varying parcentages. Never noticed any battery degradation at all. My x10 battery seemed the same as the day I got it after 2 years.
I figure any detrimental effects will probably occur after 2 years of bad practice at which point most people would have a new phone anyway

Story @ Tech Crunch.. QUESTION FOR CURRENT EVO USERS

In the story he states that the batter would last four hours? any truth to this? he also explained that there is lag in the sense?
http://techcrunch.com/2010/05/29/htc-evo-4g/
Maybe 4 hours of non-stop web browsing with the brightness all the way up while on 4G. Also, I've never had any lag with Sense.

The battery is is very poor. I'm not exactly sure why that's the case since the EVO doesn't report the screen as a large draw. For example, I unplug my EVO, connect my Bluetooth headset and listen to a podcast for 10 minutes. That drains the battery to 92% from a full charge.
You will most likely have to carry a spare battery to get through the day, with light usage.
I'm hoping its an optimization issue and they can fix the battery issue with an update. Fingers crossed.

hmm, alright i mean this is big for a person who is out 24-7. (arnt we all) i wonder if it has to do with anything similar to what the hero had when it was released.
My battery life is not perfect. But people always have this problem. I was a G1 owner and everyone complained about the battery life when it first came out. And then slowly after a mont or two everybody stopped...why? Because the battery life got better with time. From 5 hours or so to 9 or 10 hours.
Then I went to an HD2. The first week I was so scared I had made a huge mistake because the battery would last about 4 or 5 hours. After I did as suggested and let the battery completely burn out and then completely recharge for about three cycles, the HD2 had the best battery I had ever seen. i could use it for 2 days and have 60% left.
Now I have an Evo. And the first stay (with constant use) it died after about 4.5 hours. But I am going through the process of draining and then FULL recharge of 6-8 hours and I'm sure it will be fine.
People think they plug the phone in an hour or two and it says 100% and they have charged it. My opinion is that it takes the battery a while to know what 100% and 0% are on any given battery. After it cycles through a few times it will actually have a true accounting of the battery life, power consumption.
That is all my opinion and experience. I am hoping the EVO has a similar battery life to the HD2. That would be perfect for me.
EDIT: And as for lag....the guy is obviously on crack and just saying stuff to say stuff. I doubt he even has an EVO. He's reading about Sense Lag on the HD2 which there was some) and passing that information on. Anyone who actually HAS an evo have any lag? I think not.
And if he thinks an iPhone 3GS in ANY way blows the EVO out of the water...he is obviously lying. I mean based on feature set alone. There is no way the iphone can browse as fast (4G...hello), operate as fast (gee isn't that processor almost twice as fast), take better pictures? No. Have a front facing cam? No. Oh yeah...that screen size on the iPhone sure is better than the EVO. WTF?

I understand what you are saying. That was the only reason i am worried about buying an EVO. This author must have had all the applications syncing every 15 minutes. I have an apple itouch not sure how close the phone and this thing is but I like it. It is smooth and quick. (buts its not a phone). When it comes to android... Its about the experience that comes with it.
But this guy is positively being paid off haha

With light usage I had 36% remaining after 14 hours the other day. I think you just need to give the battery time to get adjusted. However, I have noticed that it seems to drain faster from 100-80% than it does from 80-50%.

Well I actually just recently noticed the same about my iPhone 3G. The first 10-15% go really fast.
My evo seems to do pretty good with the battery I can go the whole day without needing a charge but I do charge it when I get home. When I'm using it for games all day it drains pretty quick but at those time I plug it in... I don't know what they expect when your rocking a 1ghz processor, a 4.3 inch screen, and about every type of network connection you can fit in a phone... as far as lag goes on this phone I notice very little mainly when I'm installing like 3 or 4 apps at once... compared to my hero this thing is a rocket! And once Android 2.2 is put on here this thing will be smoking.

My Evo lasts for 8-9 hours. That's 70% idle with screen off. Cell Standby at 40+% is killing my battery.
My motorola droid in the same time still has over 50% charge. There's no question that the Evo is a battery drainer for whatever reason.
hate to say it, but once a fan boy always a fan boy. I used to have a win-mo device (touch pro) and i like it, then i moved up (should i say downgraded) to the instinct- worst decision ever. than i used the android platform on my hero. I'd have to say its leaps and bounds easier than win-mo.. My brother has an iPhone which i always play with when he comes over, and i think its a really easy interface to play with.. thats all. The speeds at which apps were open weren't any better than my hero. I also opened up maps on his phone and mine, and my location was dead on with the hero, the iPhone was 100meters. LOL.
But everyone needs to try other stuff out and make there own decisions, dont let someone who is obviously a fan boy tell you whats good and bad.

thats ur prob ur using bluetooth it will use more battery and then ur playing the podcast at the same time any phone u do that on u will use more battery
the battery technology is a few years old. the cpu is 1ghz.. the phone is sniffing 3g/4g/wifi/bt plus the shiny screen and backlight all use power. the battery technology being used in this state of the art phone is not advancing as fast as the phones are...
the reason the top ~10% of the charge goes so quickly is due to the you taking the phone off charge.. the cells in Li-ION batteries are not created equal. some cells will get a stronger/longer charge than other cells. once you take the battery off charge, the cells that are stronger in charge than the others will feed that extra charge to those other cells, so your battery charge will fall down to around 90 or so pretty quickly out the gate.. from there the cells are all stable and equally charged and stay at a constant discharge rate for about ~87% to about ~55%.
once the charge falls below 55% the cells really start to lose their charge and the battery curve drops drastically.
when you "top off" the phone for , say, 30 minutes or so and you take it off charge and you see 100%. do understand that one or two cells have a fuller (my word) charge than others.. once the cells equalize, then you will see the tru charge (which will be much much less than 100%)...
I'll post my findings here although probably no one will believe me. I'm not a fanboi since i've phones on three carriers.
My EVO will lose 2% per hour sitting idle which is fantastic. My HD2 loses approx. the same amount, maybe a little less.
I've found the EVO to be no more power hungry than any "superphone" i've used including the iphone 3gs.
signal strength also plays a part
one thought based on my experience with a palm pre and htc hero: signal strength.
My office has very low signal strength (1 bar or less). The battery seems to drain quite fast here. If I'm somewhere else with good signal, my battery lasts much longer. Same battery drain if you're going in and out of evdo / 1Rxx.
Sean
My battery life is like all the other phones i had lately (see my sig).
No more, no less.
I have to say my battery is getting better with going through a couple full charges, as for lag nope none not here
“Phone idle,” and “Android system” that eat up over 75% of the life.

LMAO, the fact that he wrote that puts severe doubt in his skills to review an android phone.
I can't believe this thread is going on seeing as that's an Apple Fanboy site. Will say anything to make his Iphone sound like the best thing ever. He lost all credibility when he said the Nexus One and Incredible were better phones.

the battery in the EVO (and pretty much every phone evar) is a single cell battery.
you have no idea what your talking about do you?

Battery life survey?

I haven't been able to find any threads that already cover this. There are several reviews, users' opinions etc on how long the battery in a particular smartphone lasts, but it's always struck me as odd that this information isn't easy to compare - it could lead to name-and-shame for particularly bad phones or encouraging results for those manufacturers who actually cared & made improvements.
I've found a few people who had the same idea, and one of them (being a much more web-capable person than me) actually made a website for this purpose. I really don't want this to sound like advertising, because the purpose isn't to make anyone any money, but simply to centralise this kind of information and have some (arguably) more meaningful stats driven by and for the benefit of everyone who wants to know.
If you think this could work & be a good idea, please take a look at the site - http://www.wewantbatterylife.com/ . If you think it's a rubbish idea and/or have objections, flame away.
the li-ion batteries normaly have longer life than the old phones...so it will last enough time..u'll probably replace your phone before the battery dies Probably u can ruin it with overclocking your device or something..but draining is something else
ps: im trollling again :O
Hehe, I meant battery life as in "how long does your battery last from a full charge until it runs out?", but yes, mini-troll It's all good..
Hi,
I have another question about batterie life. I don't know if it has been already treated somewhere else in the forum.
I will receive the 2000mha batterie today. What is the best way to calibrate it?
Fully discharge it then full charge or full charge before first use?
Thanks for you help!

my battery in nexus s long about 4 houres in full use , that is problem ?
what can i do ?
Nice site, and it will only grow more useful the more people input their info. Although looking at the results, some of those 30+ hour claims seem outlandish.
my stock galaxy note battery takes me 6 hours to lose 50%. hope it could last longer.
On my Galaxy S running ICS 4.0.4 Dark Knight 2.2, my battery lose about 25% by day. But with light use (1 or 2 calls, some SMS, GMail sync, ...)
really miss the days with my old nokia which i only needed to charge every two or three days haha.....

my phone keep charged almost 1 day
I don't know if it happen for someone else but i noticed a sort of "bug" with my HTC HD7. (Bought in December 2010)
If i reboot my phone when the charge is at X%, after the reboot, the charge level will be ~10% less than X ... and the phone will stay a very very long time at this percentage.
(For exemple, if after a reboot, i'm at 75%, the battery could stay at this level for all the day)
So as I imagine, it decalibrates the battery level and to make a new time the calibration i have to let my phone fully discharge and fully recharge to solve this bug.
Strange ...
(Sorry for my english guys, I hope i can be understand)
It seems that smartphones need more juice daily. However if you disconnect the mobile packet data whenever you are in range of WLAN you might get 2 days with one charge.
I am actually quite amazed how well my Samsung Galaxy S1 original battery has lasted almost 2 years. When I first started this smartphone journey with my S1 I thought that it will not last one year. I am glad that I was proven wrong.
Batteries
Definetely Smartphones need better batteries, especialy after we got used on some phones to last even 4 days like I had previously Nokia C7, and after that i bought Galaxy S2, and its battery lasts only 1 day, now thats really sad
my sgs+ with a custom rom (gigabread+) is alive up to 24 h.
My I9001 is at 30% at the end of the day (connected to wifi all the time)
battery life xperia s
my xperia s last 3 days with making some calls abou ta half an hour surfing on 3g a day and sometimes a game but when i use it a lot is lasts about one day and a half
HTC HD2 on nand android does ~4-6mah an hour on standbay, depending on torture i give it, it lasts a day to a day and half
My Samsung Note (stock 4.0.3), WiFi on all day, and average use (business mail, whats-app, games, some browsing)
after 15 hours the battery is still 40%~50%
i use SetCPU, it throttles up the CPU if its needed, at idle it runs at 200 MHz instead of 1.4 GHz
My SGS2 can last almost 2 days without using data. Its pretty good on battery

Got an extended battery...

...and its wicked (IMO..I've heard others not have good luck with them..)
Basically, I've gotten 22 hours of fairly heavy use.. web surfing, Facebook, gaming (order and chaos mostly) among other things....using auto-brightness.
Now that I have another battery...I'm going to unlock/root and get to work flashing like I did on my DX.
A question though.. If I use my extended battery exclusively, and keep my standard battery as backup... Will my standard slowly discharge over time not being plugged in? Idk much about batteries..
Thanks so much,

It will yes, expect it to loose approx 30% over a period of a year being idle. Nothing to worry about.
Oh okay. So popping it in once a month should keep it up then?
I just want to be sure I have one handy because I once got into a corner with my DX where I needed a full battery to .sbf and mine was half dead and wouldn't work...so I had to hunt a friend who also had a DX down to fix it lol. Just want to be sure I don't run into the same problem >.>

It will lose very little capacity not being used. He meant it will lose charge just sitting there. Just don't let it sit empty. Or at full charge.

You should be fine, lithium-ion batteries hold their charge pretty well. I've not actually tested them before, but try charging it to full and then booting up to see the charge in 28 days later, might be interesting to see.
I know my Nikon D7000 batteries hold their charge very well, I tend to leave one in the camera and discharge the one in the battery grip first and just use the battery for a month or so and swap them around. In the same sort of time, 28 days I can lose up to six percent this time of year, but I am going out everyday in temperatures as low as -12°C, so it's to be expected.

For this Id like to know some additional information... what widgets you have running. Stock or ROM and what kernel. As well as settings like display, sync timing etc.
If you want to store your LiIon battery it's best for the battery to have ~40% charge. The battery will age the slowest this way.
Do not store it at 100% or 0%. Check every 6 months and recharge to ~40% if necessary.

This also reinforces what I've heard. Store these type of batteries around 1/2 charge never full never empty.

How to best charge Note 7

I think the batter is the weak link in this phone. Actually, I think it was that in my Note 4 too. After a good year, my phone started bootlooping and it was the battery's fault. I am not too confident in Samsung's batterys, not because of explosions but because they seem to be not the best. The problem is, if we want to change Note 7's battery, it will have to be done at the service center. So I'd like to keep the battery in good condition for as long as possible.
I have read it is best to avoid fast charging. I also read it is best to keep the charge between 40-80% and not let it charge over night. And to only let it drain to 0 and charge to 100 once a month to recalibrate it.
Do you guys think these are good tips for the Note 7?
I also read that first time I should have let it chargefor 5 hours, which I didn't first mistake there? Thanks everyone.

From what I have researched from chemical engineers who design batteries etc the best thing to do is not allow the battery to discharge below 20% and not charge it over 90%. Fast charging apparently does shorten battery life but all charging methods shorten battery life. All about heat, so they say? In 'normal use', whatever that is, a typical mobile battery could last years?
In thinking about this I have owned since the early 80's maybe over 100 mobile phones and 100 other mobile devices and have never replaced a battery yet? I have friends and family still using some of my hand me downs and they are still going strong.
Appears a very hit and miss science?
Ryland
I am pretty sure I count as a normal user. I also don't think I exposed the Note 4 to too much heat or did terribly stupid things with the battery. Did I just get a bad one, maybe.
It sounds to me that you've been paying too much attention to the battery, stop worrying and you'll enjoy the phone even more.
never let the batt go to 0%, charge max at 90%, thats all you can do, and, dont worry too much, enjoy your note 7
This is off of Samsung site...
Cell phones, originally used for little more than calls and text messages, have evolved into all-in-one entertainment devices. Your smartphone plays videos, music and games, and many include lightning-fast Web browsing and a robust app library. Use these features for more than a few hours, though, and your phone's battery charge may not last longer than a day. You can coax more life out of your phone by charging the battery correctly and tweaking a few power-hungry settings.
Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.

I've researched this and tested it for myself not saying this is the answer. I use to go 100 to zero with note 3 trying to see how far I could go screen on time. Biggest mistake I've read from Samsung and makers of lith batteries to not let it go below 60 amd it's ok to top it off as often as possible. Leaving on charger doesn't effect them due to them never fully charging they trickle charge my wife does this every night with note 4 no issues same battery for a year. You get 500 cycles of charge if you deplete 100 to zero it makes the battery unstable when hitting zero lith don't like it. You get 2500 cycles if you do the 75 to 100. I've topped off my note 7 every day lowest going to 60. I play music for 3 hours walking outside only lose 2 percent of battery. Using hotspot I lose 5 percent in a few hours all been the same the way i charge. I had 2 other note 7s I did the opposite. In a week I would lose 20 40 percent battery with hotspot music not as good either. Learn the mechanics other the battery how they work wiki it. Look at the science not opinions or articles. That helped me in the long run. I keep a Poweradd Apollo with me just in case.

Well if Samsung put that info on their page it really about says it all.
Back to stationary phones I guess. I don't want to have to take this phone to the service centre in ten months or so.

Have you read the replies here?
No device can go forever without an eventual battery change. As I said I have owned hundreds of mobile devices spanning FOUR DECADES and have never replaced a battery.
How did you arrive at a 10 month replacement figure?
Ryland
Yes, mostly they don't agree with you . And ten month figure from my experience with Note 4. At 10 months it started being weak, then after a few more months, bootlooping started and it was just because of battery. I love Notes but just don't think they have good batteris to begin with.

If you have a doubt regarding a mobile don't buy it especially an uber one like the Note 7 etc. If you are very concerned about battery and its going to cause you worry go for a brand with removable battery. No one can asses how you use your phone and how long the battery will live.
Sounds like you had a bad experience with your previous mobile and that has caused you some anxiety. All one can do is relate our experiences to you and hope you can make a judgement call based on others opinions?
I have zero reason to suspect the battery life of the Note 7 to be any weaker than my previous mobile devices. Only time will tell. The battery on my crystal ball needs charging.
I wish you well.

I gave my son my note 3 when I got the note 4, the note 3 is now almost 3 years old, and the batt is still reliable, not as when new, but very dependable
I try to plug in my phone when the battery hits 40% and charge it up to 80%. I dont get to strictly follow it but that's the best way to preserve battery life/performance

Best way to use battery mods...

So I am curious how people are using their battery mods? I have a Tumi that came with my phone (swappa). I am grateful to have it though I realize it may be unneeded with the Z play. I was surprise the first time I used it to notice the phone does not sleep with the battery mod on. Is this normal? It correctly kept it at 80% for most of the day but I believe it probably wasted quite a bit of energy doing it.
Another thing I was surprised at was how HOT the MZP got when I charged it with the turbo charger. It was fast! I am curious at what cost this speed comes at. I am tempted to leave the battery mod on and charge wirelessly over night. This would be a much slower charge and possibly better for the phone's battery. I have had bad luck with batteries going bad and I would like to care for this one the best way possible. Would this be be better than just running a turbo charge for an hour each morning before leaving the house? I expect the phone will last the day without the battery mod without problems.
Anyway... I am curious to hear how others are managing their battery and using the battery mods in you have one. I am sure I can learn a thing or two. Also, any research on if turbo-charging decreases the life of the battery? I know they are designed for it, but they are also designed to last a little over a year. Moto won't be upset if I have to buy a new phone in two years. Thanks for the conversation!
Despite of what the research articles on Internet says, I have stopped plugging in my devices overnight on regular basis after I have had my share of bad luck with swollen batteries. I don't have a battery mod for my z play but I try to care for my battery as much as possible. Since phone gets charged in less than 2 hours with turbo charger, I generally charge it in day time or before going to bed. If I am at home and I am not in a hurry, I use a normal charger to charge my phone. It's well known that heat the known enemy of batteries and whenever I plug in turbo charger, my phone gets hot. Highest is 42 degrees only though ( ambient environments plays a role). As summers are approaching here, I simply switch on the fan whenever I charge using turbo charger.
Though turbo chargers are designed to charge fast acconpnained by the compatible chipset, I highly doubt that companies had some real progress in lithium batteries and they are not meant to be tinkled like that so I am a bit sckeptical regarding long term battery health when constantly used with turbo chargers.
