Hello guys ive been reading tips about battery lately but i haven't decide what is best for it. My note 4 i still have it , i charge it very very randomly , after 1year i still have 1 day of battery so i didn't do anything bad to it even if i charged it so randomly . There are alot of informations on forums that say that battery should be charged from 30-50 too 70-90 and once a month , u let it completly drain ( till the phone shuts down itself ) for recalibration . I usualy charge my s6 from 20 to 100% , but ive read that this is bad too. I don't know what to think about it and i would like some other people to tell me how they are charging it . Sorry for my english.
It's all rubbish.
It's a battery, it'll have 3 pins, a positive, a negative and a thermistor pin, that's it, there are no electronics inside the battery, it's just a simple chemical Li-Ion battery. I expect when the phone dies at 0% this isn't actually 0% at all, more a feature in software to make sure the battery doesn't get damaged. There is no such thing as 'calibration'.
Do some reading on Litherion Ion cells and you'll see just how much rubbish is scattered by people on here.
Yeah, like the old not leaving it plugged in overnight myth. I've lost count of the times I've seen that one.
To be honest with you , i don't believe everything i read about batteries and im sure im not going to drain the battery once a month just for the fun of it. Still , i am going to charge it to full every time because its easy for me to plug it in and let it sit like 2hrs and get it full than to watch over it and stop it from charging at 80% , when its green,i take itoff and that's it.
One thing to note though, which is true, is don't ever leave a flat battery flat for a long period of time as this will reduce its efficiency in the long run.
Noted. So , one more thing , what should we do , charge from 20-30 or whatever to FULL or to 80% as they say it's not OK to go full.

Well , samsung reply was satisfying . So i guess if someone would really want to care about the battery lifespan , should discharge phone ( till it shutdown itself ) and recharge from time to time (1 /month ) .
Samsung reply with :
" Regarding the charging of your device, all of the scenarios you describe shouldn't have any particular negative affect on your battery. However, completely discharging a battery from time to time can help to extend its operational life by a small amount. "
( The scenearios i described are the same as in the first post of this thread )

Hello all, I would like to know what % to start charging my phone is better to the battery? it's draining so much and there is no extra battery for sell in my country yet.
I did search many posts and all answers are different. I am so serious only this and I hope I can have a better way to keep my battery longer... thanks for your attention.
it's usually not good to let the battery totally discharge. So charge it before it completely dies.
oh really... but I already made my Note battery to 0% and shut off itself two times I also did charge on 40-50% to 100% bcoz I know I would have to stay outside without battery charge after. I wish I can get an extra battery in my country soon.
Your problem is probably not related to the battery but to some apparently draining all the juice. There is an app called something like betterbatterystats, not sure on the spelling though, it might help you to find those draining apps. It's been reported manytimes here in XDA.
And for your information it's better to charge when the battery dies for the first couples of times. I don't think that it makes a big difference after that.

U may also want to check the process or apps running on the background?
I freezes all the unwanted apps or process les one by one to try it. But in terms of the batt usage, I believe if u don't use it much often u can still stand by for at least a day. Mine running on full 3G, but screen brightness set to lowest and STILL facing some batt drain issue.

Charging from a total 0 is actually good and most technical people will suggest the same. In fact a full battery drain every month and then a full charge ensures your battery gets a full charge and a complete battery rotation. This is a good thing that you did and let no one tell you otherwise.
However, for normal usage the lower the better at which point you charge is best.
All of these batteries comes with xx full cycle charges - meaning how many times they will last from 0 to 100% before they degrade and start giving less efficiency (around 85% on future charges) after the full cycle charges are over.
You may want to use 10% as a good benchmark to ensure you dont lose an important call with your phone off. The battery saving mode on the Note will also help you reduce loads at times and improve battery life (at cost of system power).
Congratulations on using the Galaxy Note, which I feel is the best all in one device in the market!

I second this.. its funny how still people still believe those myths about batteries (like charge 100% before you use the device first time).. those issues are easy 5-10 years old.. batteries now a days a have smart chips built into them that can control the battery health
So, I can charge my battery anytime when needed?
Also, for screen brightness, i set auto brightness is better than setting it manually low?

So i recently flashed CleanDFT ROM, first couple of days the meter read out 1 day and 18 hours which im very surprised then it went down to 1 day and 4 hours, now this morning i unplugged and it tells me i got 19 hours left from full charge, should i go by this? or is there something wrong?
hello can you help me wid flashing...i came from android...no idea of how to do it...

Redirecting you to the right place.
If you have just flashed a new rom, in general, you need to go through a couple of battery cycles before the battery read can be accurate. I remember when flashing my ATT FUze I had to wait 2-3 complete charging cycles ie. discharging battery to 10% and charging back to full before I could get accurate reading. If you are experiencing worse battery time than before flashing after 2-3 cycles you might need to reflash the rom; you should see better battery time with custom roms, so I have heard.
I also wouldn't go by the battery saver timing, I would go by wpbench or real time use to get an accurate reading on battery time. I have a 1800 mah battery in my focus and it reads 24 hours on battery life
As far as i know, doesnt all the ROMs have basically the same battery life?
Ill be going out of town sometime this week and ill be out most of the day, i need a rom thatll at least last a whole 12 to 14 hours at the most or whole day at best of just occasional twittering and occasional checks on facebook and probably capture some pictures and a video and maybe an hour at most on music? im sure this phone can handle it but idk what you guys suggest
I have the same issue with ATT samsung focus with Roger latest updates, the battery meter is just not accurate, sometimes full and just reboot upon eject from the micro usb. The battery was fine until recently. Found a few other with the same issue online, no solution available yet.
*pulling out battery doesn't work*
The solution is exactly the same as it is on a laptop.
Lithium ion batteries, and, actually, come to think of it, pretty all rechargeable batteries lose capacity over time. The phone, to begin with, doesn't have a good idea of how much capacity is left, and it has to estimate based on previous performance. This is partially a result of battery manufacturers going as cheap as possible with the circuitry in lithium ion batteries.
The phone needs to figure out how old your battery is. This data is definitely lost with a new rom. Leave it to charge overnight, then unplug it and let the battery run all the way to dead. Charge it again, and your battery percentages should be correct. It may take more than one cycle, but the meter should settle into a correct estimate eventually.
Incorrect battery stats are a possible reason for fluctuations in battery life and reseting them as described in the previous post can help.
Another thing which you can do is use an app like this http://forum.xda-developers.com/showthread.php?t=1328730 to check the reported mV rating of your battery at full charge. That can serve as an indicator of the battery life you can expect with your current battery stats.
Hello friends,
Here finally I upgraded to ICS and honestly I get great ( huge ) battery life..
before also I get upgrade and i get very low battery life because of low calibration of battery without my knowledge..
so I've reverted back to gingerbread 2.3.5 and I'm happy
But who wants older version when the new shiny and superb upgrade of ICS is there anyone ???
So finally I upgraded to ICS and after many searching ,, finding ,,, reading and confusion with doubt The great battery life will be came out from our Loving SGN.. so please do not get disappointed just see below.
Really here I provide you some small and very easy steps by using it you will be definitely be happy with your ICS upgrade ..
you doesn't have to go anywhere and doesn't have to buy anything with your valuable money ..
Really happy
Then read it and get longer and more juice from your battery..
you have to follow some easy steps below
1 . First upgrade your ICS from any source whichever you like ... by kies air or Kies on PC or mobile odin or Via PC ODIN [ please do full charge of battery before any upgrade low battery can make your phone unusable or dead you can get more info on other threads ]
2 . Hope you have upgraded successfully.. then use your phone till your battery goes down to 5 % or below...
[ Caution ] Do not use it till it switched off automatically.
3 . Plug your charger and charge it till morning if you are charging at night or else charge it around 6 to 7 Hours even after full charged .. it's important step.. Do not Ignore it ..
4 . and then use it as per your requirements till battery shows 5% or below
5 . Repeat the step 3
6 . Do it around 8 or more charging cycles.
You get really miracle after 3 or 4 full cycles...
[ caution ] do not overcharge after that i.e just do 6 to 7 hours charging for around 5 - 6 cycles ... after that charge till battery shows full charge i.e around 3 - 4 hours. do not overcharge ..
made it habit of full charge cycles if you are comfortable with it. it really gives great battery life then average battery life.
Hope It'll be helpful to you
Regards
It is better to charge randomly than doing full charges every time on Li-Ion batteries.
Doing full charges every time on Li-Ion will result in battery being end-of-life faster...
Overcharging is also bull****. The phone automatically stops charging the battery when it's fully charged.

As per research the full cycles of Li-on battery gives good hold of charge and also batter life..
in all honesty your post is as useless as mine right now.
According to me, It can be considered as myth . . If the battery needed to be calibrated then it must have been official.. n 2ndly the procedure above is not professional at all... So dnt even think it wud work.... Neways someone can always try and authenticate...:thumbup:

Doing full charges for calibrating the battery: no problem if you do it once in a while
But you are suggesting people to ALWAYS do full charges on their Li-Ion battery...
8-10 cycles after eachother is too much as well. 2 charges will be enough.
thanks for more info bro
maybe 2 is enough but in many cases it'll be not...
Why do you need to do this just because the OS has changed? And if so then why is it not require on GB?

I totally agree with you!
Also, never let a battery dry for long periods, it will be damaged beyond repair.
Lithium Ion batteries perform better when you keep it as charged as possible.
I call this thread BS too... But I thank the user for the effort
Yeah ICS battery life sucks. I've done what OP said and I still get 4 hours less Battery life than what gingerbread would give me.

It's essential because all the states of your battery will be wiped in most of the cases while you upgrade also it's helpful to you if you upgrade your ROM.

ok bro try this procedure and also report us..
In most of cases we have solved this issue with this procedure even i had this issue before now it works like a charm.
I did several full drain and full charge cycles when I upgraded to ICS. Still got the battery drain bug so I think its more luck than anything else if your battery lasts.
In my case I've discovered that power cycling the device after charging is the most reliable approach.
Install CPU Spy, run it after a charge, reset the timers, and then leave your phone in standby (screen off) for 30s or so. Unlock the phone again, and check CPU Spy - if the 'Deep Sleep' cycle is unused then do a phone restart. This has worked EVERY time for both me and a friend who I told about it. I'm getting similar battery performance to when I was running GB!
Battery life depends on a lot of things, ROM version is not the main thing.
This is my setup:
ICS version LQ3
Speedmod 3-3 Kernel
Disabled a lot of Samsung stuff (Readers hub, social hub...)
No automatic sync of twitter, e-mail, etc
I get pretty much zero battery drain when in deep sleep mode.
Of course when using the phone, screen on, Wifi On, autobrightness... battery usage is bigger and you can drain the battery in only 4 hours if you go for it.
Be careful with:
- Live wallpapers, I've seen cases where they remain active all the time
- Apps syncing data on background every few minutes (facebook, twitter, etc)
- Apps uploading a lot of data on background (google+, dropbox..)
- Games that crash and leave the CPU in a high power state until you reboot
Agree

I am agree with this reply.
If you want to get best battery back-up;
Disable all apps which are working in background, sync n update really eat the phone battery.
I am using my note with active mobile network or wi-fi for a whole day and playing games too without doing this F**KING trick.
The only way battery life gets sucked of Galaxy note is if it doesn't go into deep sleep when not in use.
To all those reporting low battery life: How much battery do you end up losing overnight. ( approx 6-8 hrs)
I typically lose <5 % ( best case scenario has been 1 %)
I had a problem last week and lost 30% overnight and found that it deep go into deep sleep.
and the best solution i found in another thread was to unlock the phone before unplugging from charger
Simply try it: For me normal time between charges is 36 hrs ( battery is near 25% level)

Many people are of the myth of overcharging n recharging, but its not true wIth lithium batteries, phone will automatically stop charging, if only anything helps its battery calibration,u can do this with a free app called battery calibration, time for the tread to be regarded as close, still useful for noobs

Didn't find a main thread for silly questions such as this so hope it wasn't wrong for me to post this here, but I currently find myself in my phone going as low as 50% on a daily basis and I charge it next day at not lower then 40%, will this wear out the battery? am I really supposed to charge it when it's really low? Thanks.

The latest in Li-ion batteries, as the one in our phones, one duty cycle is when you use 100% of the charge.
That is ifyou go from 100 to 0 that's one cycle.
If you go from 100 to 50, recharge and again 100 to 50, that's one cycle.
Batteries wear out depending on the number of duty cycles. More duty cycles, more wear.
So what you are doing will not wear out the battery.
Also I'm not sure about this, but it is recommended that newer batteries should not be completely discharged.
Please correct me if I'm wrong, anyone else who can confirm.

Modern batteries are not like older (10 years+) batteries. I'm not about to write a wall of facts here etc. etc, but I only have one thing to tell you:
Use your device, and don't worry about the battery. It'll do just fine until the day you decide to buy a new device. Now stop worrying and just use it.

Same here, these batteries are tough. I am anal about my phone battery being charged. Haven't had an issue for years and I expect the same performance out of my S7E
Topping up your battery before it is fully discharged is the best way to extend your battery life. Modern batteries run best between 40%-80% charge. Minimize the number of times you fully discharge the battery as that is more likely to wear out the battery, although it is ok to use it until the phone shuts off once in a while.
Very impressed with the battery of the S7E. I charged to 100% last night and didn't charge until just an hr ago and was at 47%. Normal use in the morning til now. In n out of meeting, so its doing its job.
Now back to the topic of this thread, i've read some say these newer batteries should be power cycled at least once a month. Any one recommend that or against it? Haven't done it myself but did it a few times on my iPhone 6 Plus and that thing had an awesome battery even though its actually smaller than the S7E. Thoughts???

I've seen it recommended as often as once per month or as infrequently as once every 3 months. The general consensus is that it can be beneficial in that it can correct any issues that the phone software has in determining the battery's capacity, not that it is actually helping the battery itself.
Yup, I did that once in a while with my previous device (a Sony), and the battery on that one is still very good after nearly three years. I wouldn't do it that often though, but it's useful to do it when you notice the battery meter hangs on the lower numbers (like if 10% hangs for an unusually long time) or you've just flashed a ROM. The OS tends to get a little confused after some time, so it's okay to do it to "calibrate" the system again.
Thanks for the helpful replies guys.
Draining a Lithium battery to zero is one of the worst things you can to an Li battery. Don't do it. Period. Ever.
Yes, don't power cycle a battery. It MAY help give a more accurate battery reading, but it's messing up the longevity.

hello friends ,i got a new battery (it seems original) and installed it but i have weird problems with the percentage that the phone shows .
-the battery lasts for 9h sot even with some benchmarks on latest pie ob ,so its definitely not bad
-the problem is that when it gets to 10% then it goes 9 8 7.. till 0% in about 5 minutes and then shuts off with a dead battery screen .
-i noticed that the phone still charges when it reaches 100% charges at 1 amp and gets to 0 amps after 20 minutes ,i also noticed that the idle/screen off drain is very very low ,it probably has to do something with the battery calibration
i tried:
going full stock with stock recovery but the issue persists,
doing some all night power off charges to 100%
searched most of the threads everywhere ,but no one has an exact answer .
is there any way i can access the discharging algorithm so i can tweak it ,or if is a way to teach it be more precise?
thanks so much for everyone willing to help ,sory for the long post ,i wanted to be as precise as possible i can provide everything you ask for to fix it .
p.s. i study electrical engineering so be free to use scientific terms.

it was 9 sot hours with 3 hours of geekbench battery test (about 14%/hour lost) without any tweaks at all , completely stock ... that's the reason i am trying to fix this issue,the performance is insane ..(every calibration app shows at least 99% health,it even recharges way faster that the old one ,3.8A 10 to 100 in 45 minutes) if it wasn't that i would swap it back with the stock ..

Technically you want to avoid the battery dropping below 20% anyway (If you believe the words from Samsung) so it shouldn't really be an issue.
One thing you can try though is to install L Speed from the play store (require root) and use the battery calibration tool to see if that helps. Outside of this I cant really think of any thing else other than to just deal with it as is.
i figured it out guys...the thermistor in the battery was dead , i though a solution for anyone face the same problem ,desolder the control board from the original battery then solder it to the new one ,the cells are healthier so the battery will be good as new ?
