draining the battery - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

Is it a myth or truth, that it will help my battery life if I completely drain my battery down and fully charge it up? I've yet to do this in the 2 weeks I've had this phone. I know it was the case many years ago and not sure with todays batteries. Something about building up the battery memory. I'm down to 23% as I type this.

google is your friend sir. that is only for the old NiCad batteries. from what ive read you actually dont really want to completely drain any battery because it becomes unstable at that point. the main tips are to keep it cool. top it off when you can, most say to plug it up around 50 %, dont leave it on charge forever. and dont extra load the battery. ( some people take it out at 100% and plug it back in to get the most juice out of it)

Some recommend it once a month, and some do it every other months. One time doesn't hurt

I for the last 5 years or so have never done any of that and can tell you I never have had issues with my battery
BAD ASS NOTE 4

Haha Anyone that tells you that it is good or makes a difference to totally discharge a battery and then charge it to fill will help the battery doesn't know what they are talking about. Only the old Ni-Cad (Nickel Cadium) batteries developed memory and needed full cycle discharges. The new batteries that are in phones Li-Ion (Lithium-Ion) do not develop a memory. In fact these batteries have a number of cycles before they go bad. Batteryuniversity.com explains that routinely charging a battery when it's under 25% will yield roughly 300 or so cycles (charging to full). At 50% remaining Battery you will get 1000-1200 charge cycles and charging the battery when 75% remaining you can get as many as 2000 charge cycles.
So the point is never let it drain all the way, and charge frequently. My Note 4 gets about 8-10 hours of screen on time and my average days I have about 2-3 hours of sot and charge my phone 70-80% battery left. My note 3 was the same and had it for a year and when I sold it a month ago. I was still getting the same battery life. Maybe 3-5% more drain from when I got it.

Yup. Same here. I charge the battery whenever I want... And let die if it has to. Plus, it's the enclosed battery users that should worry about that.

[Q] When should i charge the battery?

hi!
guys, when should i charge the Galaxy S battery to maximize his life?
In my old phone, i only charge it when the phone shuts down himself. It can run for 7 days with no problems until i need to charge again.
Should i do the same thing with Galaxy S battery?
Well, when i need to connect the phone to the PC using USB cable, it will charge anyway. Is it bad? Should i do it only when i know the battery needs to be charged (when it has low battery)?
any time you want
it should always be topped up, there is no memory effect
Some people say that we should charge when the phone has 25% or 30% of the battery. And every month we should make a complete charge and discharge.
Is this a good method to keep the battery ok?
best way is to cycle through 2 or 3 batteries
charge them full
then use them down until you get the warning, and change to new battery pack, then take the used battery to the charger
http://forum.xda-developers.com/showthread.php?t=733705
Although I don't really have any definite sources to back this up, I've read several places that Li-Ion and Li-Polymer batteries can (and even should) be charged as often as possible. You should avoid letting them run flat, apparently.
What is certain though, is that they themselves have no memory effect like NiCd and NiMh batteries have.
our SGS will nag you to death as soon as it reaches 10%, and it will constantly annoys you to charge the battery at 5%
so, no worry about running flat
Technically to maximize the life (ie. capacity) of a Li-ion battery you should charge to full when it gets down to 40%.
The cooler the ambient temperature the better - A Li-ion battery operating at 25 degrees C will lose 20% of its capacity in one year. Higher temperatures drastically increase this degradation.
Given that most people will move to a newer phone after 2 years or so, and spare batteries are cheap as chips, it doesn't make a whole lot of difference.
So, people say that we should charge the battery when it has 30-40% of the capacity.
But what is the thechnical explanation?
Sent from my GT-I9000 using XDA App
that's exactly what i would like to know as well at 30%-40% will make the battery totally useless if that is true
might as well take the phone with a super long extension cold with you if that were true
LMAO

I don't think that would be the best strategy, AFAIK (and read)
Li-ion packs prefer more frequent charges, even if after partial discharges, than full charge-discharge cycles.
Its also not good to store the pack fully charged. Best to store at 40% charge.
Following these 2 concepts, I imagine its better to charge the battery as often as possible, like every day, than to let it discharge until you get the warning.
Also, if you cycle through several packs, letting each one discharge almost completely, then charge it fully and move to a different pack like you suggested, that means you will be letting the battery unused at full charge for a longer period (the more packages you use, the longer the pack will stay stored at full charge).
Thats how I understand the behavior of those batteries. Just my 2 cents.
Paulo
I will say what the first reply said, charge as often as you feel you have time. Do not wait for any percentage of drain. There is no memory effect and yes about once a month do one full uninterrupted cycle. The point of which is to let the device's power management recalibrate where 0 (or thereabouts and 100% of the current fill are.
Cooler is better, this is also true.
All educated advice on Li-Ion batteries is that they remain healthier for longer the fuller they are, but the chemicals must be exercised occasionally, thus the full charge cycle in one go.
One charge cycle also actually counts over multiple charges, and not just uninterrupted ones. You can drain then charge 25% 4 times and that is counted as one cycle for these batteries.
I have always stuck to this advice since I learnt of it several years back and I find my batteries work better and longer than many people I know (who stick with drain, charge methods (lack of updated information).
i agree with nailerr
Simply charge it when you need to. It's better to have a fully charged battery when you need it, than run out of battery when an important call is coming through
So, the main reason to charge it with 30%-40% left is to avoid the battery heat too much?
I found this: h**p://batterycare.net/en/guide.html
It says more or less what you guys said here.
But you need to know that i always charge from 0% to 100% my old phone. It is 4 years old and it has no problems with the battery. It can run up to 7 days without any charge... Looks like charge it that way is not so bad anyway i guess...

3500 extended battery decline in performance

I purchased the 3500 extended battery about 4 months ago. It was a great battery. It lasted me all day & then some off a single charge. Now it's not lasting as long as it used to. I'm having to charge in the middle of the day now. I put my original OEM battery in, & I'm getting better performance from it than with the 3500 battery now.
Anyone else experiencing less than stellar performance from the 3500 battery after having it for 4 months or longer?

I have the 2150 OEM, I can only suspect some reasons why
1) Cheap battery that does not hold charges well
2) You are draining the battery down to 0% a lot, killing the ability for it to keep a charge
3) Your phone is not calibrated properly so it shows it is charged to 100% but in fact it may have only charged it much lower

1) It's a Seidio brand, not some knock off, so it should be of good quality. It's been working fine up until the past month or so. I've had it for over 4 months now.
2) I've never drained the battery down to 0%. Contacted Seidio and they suggested that I let it drain to 0% for the next 4 to 5 charges, along with charging it an additional 2-3 hours after a complete charge. I'll see if that helps.
3) I've always had to bump charge it. It helps in making it last longer.
I don't think bump charging is helping the longevity of your battery. Not saying it doesn't last longer on a charge, but that it isn't good for the battery's overall lifespan.

Draining all the way down and overcharging it are the biggest ways to kill it off. The Seideo and most other batteries I think have a fail-safe for draining it all the way down, cutting it off early before it actually does.
This article is pretty helpful about your battery, if you haven't had the chance to read it, it may benefit you:

Bump charging did it.....
Where's ma rosie at?
I have been using the 3500 for about the same length of time you have been. I haven't really noticed a drop off in performance. Maybe a very slight drop off.. not much though. Still could get 2-3 days use on one charge if I wanted to.
I have the same issue with my 3500. I will try to re-calibrate it.
4 months seems to be pretty quick for a decline in performance like that. I would press Seideo to replace it.
You can try resetting the cells to how they were when it was brand new. All you have to do is completely deplete the battery of all charge (so it wont even turn on) then short it out with 3x the voltage (a 9v battery should work, make sure to keep the polarity the same) and fully charge it again, then it will be like new!
My dad (who is an electrician) found a guide for this on ebay and bought it just for the hell of it to see if it worked. We tried it on a battery I had for an LG VX8300 I had at the time and it worked beautifully, I've been doing it ever since!
I have no idea how this works, all I know is that it just does.

When ever you get a new battery you must condition it, exactly as sedio said full charge it, then drain fully 5 times. It makes the battery last much longer

I got some 3,500mAh cheapies off ebay about 6 months ago and they are holding up just fine. I always run mine down to about 5% then fully charge. I bump charge them about once a month.
Well of course... After I'm pimping how great these batteries are, one quit working! My phone would just shut off with a light tap against something so I pulled the black sticker off of the battery, pulled it all apart, found the loose connection, bent the tab to make better contact, and put it all back together. All is good again.
I recently purchased this same battery read tons of good reviews not sure how i feel about the bump charging after reading the article that was within this thread but all in all it is a giant leap beyond the stock battery now if i could just find a case that would fit around it
To the OP. If youre running a kernel with SBC (Superior battery charging [trickle charging] w/e you wanna call it) they're known to reduce your battery life. also you may wanna charge the battery to 100% then wipe the battery stats on your phone.
I have the same battery and I've found that the phone has trouble reporting the percentage correctly. It tends to make jumps of about 5-10% instead of a steady decline. I switched to the original battery and it did not have this problem. I've also noticed that clearing battery stats several times helps (most of the time). As far as bump charging goes, it's perfectly fine to bump charge these batteries. The worst thing you can do to them is discharge them all the way.
Clearing the stats and cycling the battery through the phone a few times should fix that. It does that (big percentage jumps) when it's poorly calibrated.

I second this. I have the same battery and its been off a few times. Battery stats get weird sometimes. It's certainly a better battery than the cheap Chinese batteries HTC uses.

Anyone use Better Battery Stats? Need help lowering %/per hour

So I'm burning 1.8% per hour according to BBS. Does anyone here know how to decipher the info and tell me what's the culprit?
1.8% per hour? That's not even bad. Round it up to 2%. That's 50 hours. What's wrong with that?

It may be likely that your Moto X’s battery is fine, but having trouble correctly identifying how much battery life is left.
Simply run the battery down to about five to eight percent and let it die. You can speed this up by streaming a YouTube video. Then, when the Moto X has died, let it charge for a few hours before turning it back on.

Never go to zero
Obviously, using your battery is going to make it degrade. But it's going to slowly die even if you just leave that iPad in the closet for a bit. There's a trick to minimizing that inevitable aging though: leave it a little bit of juice.
If you're going to be shelving any lithium-ion battery for a long time, try to leave it with at least 40 percent battery power to tide it over. Lithium-ion batteries don't hemmorage power at 30 percent a month like nickel-metal-hydride batteries do; they'll lose maybe five to ten percent of their charge each month.
And when lithium-ion batteries get too low—like, literally zero percent—they get seriously unstable, and dangerous to charge. To prevent explosion-type disasters if you do try to charge one, lithium-ion batteries have built-in self-destruct circuits that will disable (read: destroy) the battery for good, if it reaches rock bottom. And sure, that'll save you from a face full of battery-acid, but it'll also leave you short one battery.

Always have heard it is bad to drain the battery in a phone. I know other people swear by it, but its not worth the risk of it not charging again, or worse blowing up.
Charging sooner doesn't hurt since there is no "charge memory" like nickle based batteries. so just plug it in when you can, and if you your away from an outlet for too long, maybe it time to consider an external battery backup.
OP, here's another thread that has been discusing the same issue, its a good read.
http://forum.xda-developers.com/showthread.php?t=2418077
I burn around 6% after the last update, with no other changes to the phone. And that's with Battery Saver on too. Used to be around 1.5 to 3%. Everyone said "just wait, this always happens after an update, it will eventually settle out". Total BS. My daily battery life has been cut in half for months.
Well I did a better battery stats 6 hours test ( let it sit no touching etc ) and Im only at 1% an hour. Im pretty happy with that.
I've tweaked the crap out of my phone....and get 24+ hours with 5 1/2 to 6 1/2 hour screen times. Extremely happy......and best I've got on standby is 1ish per hour.
Again....tweaked the crap out....for battery life. LOL. So 1 percent even may take sacrifices some may not wanna make. I'd say a stock sorta phone would get 2 even and you'd be doing alright.

wow you guys are getting great battery life! According to GSam Battery Monitor, I'm at 9.7%/hour. Currently 6 hours since unplugged and I'm at 35%! With only 2 hours of screen on time.
I think I messed it up when I first got the phone. I immediately upgraded to the 2 OTA's and forgot to do a factory reset. I think I might do one now and see if it fixes the battery life.

1 percent per hour is with no use. 9.7 per hour with you using it a lot and depending what you are doing could be perfectly normal.

How long does a battery last?

I have had my note 4 a year now and have been an extreme user with lots of games, movies, Netflix, Ingressing, drawing etc.
I was wondering when I should start to get ready for a new battery?
I figure I should be getting close to its useful life soon and what to be ready since I should replace the one in the wife's note also.
6 months to a year
Sent from my SM-N910T3 using Tapatalk
Time to get new one soon. Once you start seeing battery dropping from 15-30 % to 1% within a minutes then replacement is needed. I replaced mine after 14 months. I choose anker instead samsung.
Well i have an external anker and currently always near a outlet so I never see 15% lol. But will be on amazon looking for new batteries
Proper battery cycling is key to long battery life. Allow battery to use up 90 to 95% of its charge then fully charge. Topping off battery constantly will shorten battery life drastically.

I have read many different things about when to charge, over night charging etc and pretty much from experts and no one ever says the same thing.
Topping off I have read its good and bad so when it comes to charging I will keep doing what I do now since I don't notice any loss. Hell I charge while playing games.
According to phone info app I have plugged in charger 1456 times and battery health is still good.
I just know with heavy use and games like Ingress battery won't last for ever and I am shopping now for batteries.

When should you charge and unplug your battery.

For the last few years I've been reading that it's best to charge your battery at around 30-40% up to 80 or 85%.
Despite this possibly being the best practice, I don't see much point in paying for a $1200+ with a 4100mah battery and only using 40-50% of it's capacity.
So do you charge at around 10% and then go up to a hundred?
Generally I charge when I need to. I like to be topped up to a 100% when I leave the house. Maybe this isn't best practice. I could wait until it get to about 20% but I am wary about using all the battery cycles up.
PLUS I doubt you're going to get 6-7 out SOT if you charge at around 30 or 40%.
So what do you guys do with your s10e, 10s or s10 +?
Charge it whenever. Why the heck limit myself to 60% (say from 20-80% when even my usage pattern won't cause the battery to wear down to 80% capacity over that same time frame by my charging methods?
I also don't tend to keep my phones for more than a year, so wear level doesn't really affect me much
There is no way to "charge it best". Just use it and charge it when needed.
People take out of date "battery knowledge" from the NiCAD battery days and think that modern batteries develop "memories" and things and that hasn't been the case in decades... Just use it and don't worry about it. A battery is only gonna last 2 years at best anyways, so who cares if you shorten that by 2 months?
I normally charge my S10 from 25% to 90%.
The battery of my previous S7 Edge started suffering after almost a year and a half because I used to always keep it charging overnight.
If you don't intend to keep using your phone for more than a year, then don't limit charging your phone. Even in the case it wears off after a year, you can get your battery replaced by Samsung and start fresh again.
I charge mine around 20-30% all the way to 100% . Then unplugged it whenever I need to.
Is there a good "battery charge limit" app that doesn't require root or Magisk? I used Battery Charge Limit (https://play.google.com/store/apps/details?id=com.slash.batterychargelimit&hl=en_US) and it works great, but requires root privilege. It allows you to set upper and lower limits for charging, so you don't overcharge or let your battery drain.
Batteries don't overcharge. They hit 100% and then trickle charge...
Li-Ion batteries are durable and easy to maintain, you can't overcharge them and also the charging cycles doesn't matter - when you use the integrated Charing electronics in your device. You can charge it for a few minutes over the whole day without losing any capacity. Only over the time the capacity will get lower and lower, but this is an issue you can't avoid.
The charging controller in your device cares about voltage and loading current, never put a current on a Li-Ion battery without current limiter and voltage regulator.
But Li-Ion are very sensitive to mechanical damages and production faults.
Thanks for all the advice guys. Nice to see that most of us feel the same way.
Agree with the others. Technically, for optimum life, they say it's best to be between 40%-80%.
But really, just charge it when you need to charge it. Don't worry about numbers or percentages. If you're only going to own the device for a few years, no matter how you charge your device, it's going to have absolutely no affect on the battery over that time. It'll still be holding almost the same amount of charge in a couple of years regardless of which "charging strategy" you use.
TLDR: don't worry about percentage, charge it when you feel like it or when it needs it.
Go here and follow these principles. End off.

I always stay in the range from 40/50% to 75/80% on my Galaxy Note 8 which I had for 18mos.

so you probably charge ur phone 6 times a day? no thanks
@SquireSCA I believe it's a narrow-minded approach to say that the phone battery will "last 2 years at best anyways, so who cares". I'm currently still rocking my Samsung Galaxy S5 which I bought brand new just over 5 years ago now on it's original battery. The battery is by no means like it was when it was new, but it will still last a day of light usage, and still runs perfectly fine with Android 5 installed. This preservation of the battery comes after years of charging it slowly on a charger outputting less than 1 amp and also making sure it rarely goes below 20%, spending most of it's time between 20%-80%.
If you you want to double your battery life you have to keep your li-ion battery between 3.7V and 4.2V. you have to stop the charge when the battery reach 4.2V so it means you have to keep your battery between 15%-85%.
---------- Post added at 09:24 AM ---------- Previous post was at 09:22 AM ----------
Personally I keep my battery between 15-85% which is sufficient to double it's battery life for a 3-year usage without big losses
Idk i heard ppl saying you should let it completely drain and recharge at least once a month. i charge at 15%. Oh well i only keep this phone for a year and then sell it.
It's mostly BS. There are hundreds of charging theories and no battery experts here so pick one and go with it. Pick the wrong one and instead of getting 8 hours on your batter 2 years down the road you'll probably only get 7.5 hours.
