Smart Charge Note 2 ..Increase battery life

How to smart charge the Galaxy Note 2 battery
The way you charge your device is very important and it can affect your battery life a lot. Charging it wrong will make it drain quickly and the battery will also last less, requiring a replacement after 1-2 years of use.
To smart charge the Galaxy Note 2, you have to only plug it in when the battery is below the 10% level and never unplug it until it is 100% charged.
You should also know that when your battery reaches 10%, it will last longer than usual. To understand better, it will drain much slower from 10% to 0% than from 20% to 10%. So don’t panic if your battery level is low, because it can hold for a very long time, especially in standby mode.
Never use low quality chargers, because they can damage your battery hand even the device. Only use original Galaxy Note 2 chargers and try not to use the USB cable for charging your device. Always charge it in the wall socket, because the USB port power fluctuates and can damage the battery. Also it will charge much slower.
Battery maintenance
Usually the battery is the first smartphone component that dies, having a lower lifecycle. Though you can prevent this by taking care of it.
The best way to prevent it from getting damaged is to avoid pulling it from its socket. The battery has some golden pins that can scratch or get dusty, so if you pull it out and back in multiple times you can damage the pins.
In order to help the battery work the way it should, always make sure to clean the pins with a soft cloth whenever you pull it out. This way you will keep dust away from them.
When buying a new Galaxy Note 2 battery, make sure to get an original one, as other might have a lower battery life and can have a shorter lifecycle.
Increase Galaxy Note battery life by disabling features
The Samsung Galaxy Note 2 N7100 comes with tons as features, like we just said at the beginning. But nearly all of them are big battery eaters and you need to be careful when activating them.
The CPU and display drain a lot of battery, so make sure to setup the display to turn off faster. Also don’t keep it turned on when you don’t need it.
3G and 4G are the biggest battery drainers on a smartphone. You should only keep the 3G or 4G network activated when you use the internet actively. If you really need a permanent internet connection, then go for 2G, though this eats your battery too. The best way is to only connect to the internet when you need it.
Do not keep the WiFi,Bluetooth and GPS activated when you don’t use them. They can drain your battery very fast even in idle mode, so make sure to disable them when you don’t need them anymore.
Live wallpapers are also big battery drainers. They consume a lot of CPU and RAM resources and also use your display more intensively. So you should never choose a live wallpaper. The most battery-friendly wallpaper is a dark one, which doesn’t use any CPU resources and also doesn’t requires the display to be very bright.
You also have to take care what apps you install and always look at Settings > battery to see who drains the most battery. There are some apps than run continuously and prevent your device from getting into “Deep Sleep.” This is the standby mode that helps the device conserve very much energy. If an app prevents it from getting into this mode, you will notice a very low battery life.
Please let us know if you found other ways to increase the Galaxy Note 2 battery life. We are also curious for how long did you manage to get your device running between charges.

wow thanks mate quite a good one!
Thanks!

Also you should add that if you always need to be connected to internet then its better to keep connected through WiFi as it consumes less energy than using EDGE or 3G.

What?
No.
1. Deep charge cycles on a lithium battery accelerate the failure of the battery.
2. The device can determine the type of source it's plugged into, computer usb ports are safe.
3. Non branded chargers are safe if they are quality made. You just need to stick with quality and 2 amp/ short cables for decent charge times.
Sorry man, but those 3 things you listed are some pretty big misinformation that can easily be verified.
There's nothing "smart" about doing a deep discharge if your trying to preserve a 10 dollar battery.

After installing the new rom..I charge my battery full..then remove battery stats then drain full to zero for cycle.after complete ..I use smart charge method..that is .when my cell battery below to 10 something like 9 or 8 then I connect charger .and really it helps me alot

Deep charge cycles are for avoid "memory effect" and It apply to old Ni-Cd / Ni-MH batteries. Don't apply for modern Li-Ion battery. There is much more chance that the deep drain affect negatively the battery of a GN2.
Li-Ion battery keep better performance if never going less than 50%. But the difference will be barely noticeable.
Personally, after several tests on my own, I don't bother anymore with that (I mean for the modern Li-Ion type). Sometime you have a great battery, sometime a crappy one from a bad batch. I have seen battery died fast after "by the book" charges cycles. And others seem to last forever, no matter how bad I maintained her (like my 2006's laptop).
Anyway, thanks for sharing, even if you are wrong on this one

I don't know if you're wrong or right because when you search the net about battery charging, you find everything and it's opposite. But I disagree on three points:
- The battery is beefy and you really have to work hard to make it last less than a day
- I bought this incredible phone because of it's features. If I have to cut half of them to avoid drain, why did I buy it?
- I dare say that most of the people who buy a Note 2 somewhere are a bit "Tech-Nuts". If you're not, I am, so I don't mind if my battery doesn't last two years because I'm not sure that I will still have this phone all that long.
And if I do and the battery is dead, I'll buy a new, genuine, Sammy one to continue.
What's it worth to live 100 years if you can't have a drink from time to time, maybe have a smoke or whatever? Plug your phone in or out and use your GNote 2 happy

Lol everything has its cost turn off everything to save battery what is fun in that I have a smartphone to use it and be happy with animations and display and games otherwise get a 3310 it is best

[Q] Horrible Battery Life

How is everyone finding the battery life. Personally, I am finding it just plain horrible. I'm not sure what the issue is specifically but either something is draining it or it is just really that bad, in which case I will return it. I can't get a day's worth of moderate use out of it. It seems to be at most half of what I get from my note 10.1 and they aren't set up any differently. I've tried some of the basics like turning down the screen brightness (which annoys me), turning off the smart stay (but why have a feature you can't use), tweaking email checking settings, turning off samsung sync, turning off bluetooth (don't use it), and locations services. Is anyone else seeing this as an issue and does anyone have any additional suggestions for me to try?
Thanks in Advance

I get about two days between charges on mine. I get a decent amount of usage on a daily basis between email, Facebook, and candy crush. I even have Google Now running. How many charge cycles have you been through?

If by charge cycles you mean fully discharging the phone until it shuts off, I haven't done that, but could give it a shot. It has gone down to 10% several times though.

No battery problems here. I wouldn't blame charge cycles, if they have any effect at all, it is minor. If I were you, I would do a factory reset, followed by an exchange if the reset doesn't fix it.
I have smart stay on , backlight on auto, and take no extra precautions for battery savings.

Can you please post some screen shots of your battery life at the end of a typical cycle? It will help with comparisons by giving us more details on your running apps, screen-on display times, etc. Also, what wakelocks do you have? Use BetterBatteryStats or Wakelock Detector from the Play store for that. This info might help us to identify just how much drain is related to rogue apps or the general battery life itself.

Thanks. Just downloaded BetterBatteryStatus. I'll let it run for a bit and see what comes up. I'll post what I came up with with screen shots from it. Thanks for pointing me in a direction.

Also, it'd help to know how many hours "just plain horrible" is.
I'm not delighted by the battery life I'm seeing, I'm finding I want to charge every night, and that I can easily consume 15% / hour or more even without the screen turned up past 20-25%. (watching video off the NAS in the house.)
Then again, this is the first LCD display I've been able to read in full sunlight, and that's remarkable to me. I often wind up with full sun in the morning when I get up, and am delighted that if I did charge overnight I can use the device even then.

The battery needs some initial "training".
Charge fully on the first and run it all the way down to nearly zero, and fully charge again.
DO NOT interrupt the initial charge.

Battery life is great here after 5 cycles running it to 1% and recharging full at first it was draining faster but now I can watch 4 hours of netflix and still have 25% left nice thing is that the battery charges superfast so no worries

10% is just fine, for purposes of calibrating the battery meter. Preferable actually. You shouldn't actually drain the device until shutdown. There are safeguards that are supposed to ensure the battery voltage does not drop too low (its not actually zero when the phone shuts down). However, in reality these safeguards are not always failsafe and I've seen plenty of cases on various Android devices where letting the battery drain to shutoff renders the battery unable to take a charge (below the minimum threshold voltage). Sometimes, letting the battery charge overnight will bring the battery back. Otherwise, you are pretty screwed, as the only remedy would be a battery meter with a boost function.
In any case, the battery meter is not very accurate, even under the best of circumstances, so letting it drain to 10% is plenty accurate enough. Then let it charge to 100%, and let it sit at full for a while, as fully saturating the battery takes extra time.

That said, its hard to say what "moderate use" means. Everyone uses their devices differently. If you are playing intensive games, downloading files, heavy internet usage, it can drain the battery much faster than other activities. And the number of hours of screen-on time is key. So the idea of getting some battery stats and screenshots, is a good one.
I haven't been tracking screen-on time myself. But I find the battery to be decent. I use it a good amount in the evening (don't bring it to work) mostly for reading and web browsing. I have brightness on 40-50% usually (sometimes less, if the room is darker). The battery was just under 40% after 2 nights of use (maybe 40 hours after the last charge). Just guessing, but maybe 3 or 4 hours of screen on time?
Some online reviews mentioned the battery life is not as good as some other comparable devices (such as Nexus 7 and iPad Mini). Not surprising, since the Note 8 has a faster processor and higher resolution screen than either. And so far, battery life is not amazing, but seems comparable or better (better drain while idle) than my old HTC Flyer tablet. So for me, thats just fine.

I got about 4 hours screen-on time on my first battery cycle with heavy usage. Was playing games, movies, internet browsing, etc. My second and third cycles were better, giving me 5-6 hours screen-on time with moderate to heavy usage. Didn't really play any movies, but did play a fair amount of games and stuff.
On those later cycles my screen-on drain represented about 85% of my overall drain. This leads me to say that you can expect 4.5-6.5 hours of screen-on time with the Note 8, depending on usage. Keep in mind that I keep wifi always on, disabled bluetooth/auto-sync/smart stay, stopped some running apps like Maps and Factory Test, and kept brightness down to about 15% of the max setting.
Screen is definitely the big drain here, and these results lead me to believe that even with root and apps like Greenify I would not get much better results. Looks like any further battery savings will need to come from a custom kernel and custom rom (unless maybe you root and then underclock/undervolt using a third party app like Voltage Control or SetCpu). Anyone else have similar (or different ) results?

Although the battery life is of concern to me, the fact it charges via a micro USB input rather than propriatry cable alieviates that worry (looking at you Apple). I dont think I go anywhere where there isnt a charger available thanks to the amount of devices that use them.

While his terminology might have been a bit clumsy, he is not completely incorrect.
The terminology of "training the battery" invokes the concepts of conditioning the old technology NiCad batteries to prevent memory effects, which are not a concern with Li ion batteries, which is what you seem to be referring to. Folks on XDA will often talk about conditioning or calibrating the battery, which can be a bit misleading (as often they have the behavior of the old NiCad batteries in mind when saying this).
However, it is true that the battery meter needs to be calibrated to be completely accurate. This calibration has no chemical effect on the battery itself (like it does with NiCad batteries) but simply effects how the current readings are displayed by the % battery meter on the device's screen. Without fully charging and draining the device, it doesn't have fully accurate "flags" associated the current to battery %.
http://batteryuniversity.com/learn/article/battery_calibration
Failure to calibrate the meter won't have a negative chemical effect, like failure to periodically condition a NiCad battery. And therefore it won't have an affect on the battery life. But properly calibrating will give you the most accurate % battery reading possible. The battery meter is not accurate out of the box, after a ROM flash, and an OTA may also reset the calibration.
As I've already mentioned in a previous response, I don't recommend draining the battery to shutoff. As doing so can lead to the battery no longer taking a charge, and the device no longer powering on. Its rare, but it does happen. Fully changing, then draining to 10% or so is enough. Full cycles are also not good for the long term life of the battery, although just doing it once every few months is still acceptable.

The charger for the Note 8 is 2 Amps, while most MicroUSB chargers (at least for phones and other small devices) are 1 Amp. Although this varies, and there are other tablet chargers that are also 2 Amps; but these are far less common than phone charges that just about anyone with a phone that isn't Apple will have.
What this means is that the 1 Amp charger will charge the Note 8 very slowly. I tried mine on a 1 Amp charger just once so far. Left it on for maybe an hour, and the charge only increased by a few percent.
So yes, you can charge with most MicroUSB chargers in a pinch. But it will be slow.

Don't get the physical plug of a charger confuse you - I believe this tablet needs a 2amp output from the charger, meaning just because your charger has the same end connection, it won't necessarily help you charge this battery. I've had my users come to me thinking their devices are defective because they somehow started charging their tablet with their Bluetooth headset charger.
Someone also mentioned the black wallpaper that might help with the battery consumption - I believe that is only helpful on AMOLED screens that Samsung has used on other devices.
I'm really still on the fence on keeping it after I bought this - I'm coming from a GT 7.7 which had excellent build quality,screen, and battery life. The loss of the AMOLED screen for both graphics and battery efficiency is bothering me. I put both up side by side and feel disappointed that Samsung couldn't just make a JB updated 7.7 with new CPU, 2GB RAM, and stylus with the same design and beautiful Super AMOLED Plus screen. It's not even the price - but just feeling like I'm getting a somewhat inferior device (in a few but important aspects) from the 7.7, when it's supposed to be an upgrade to the older device.
I've seen the news about an upgrade to the 7.7 possibly coming, but will it come with the stylus that is also important to me and the other software enhancements from the Note 8?

Funny thing happened on mine.
The battery was VERY BAD the second day, but it could play live streaming for two hours when the battery was 1%. As soon as the tablet went off due to depleted battery, I charged it until it went all the way until the "full battery" came up.
After that, the battery is much better now, so don't say anything "dumb" or any nonsense because it works.

That is correct, having a black background does not effect battery life on LCD screens.
On AMOLED screens, black pixels are actually not emitting light (while pixels displaying other colors emit light), which is why a black background will cause less battery drain than other colors.
On an LCD, the liquid crystal layer that depicts the colors is not itself a source of light. Its lit from the back, and the light intensity of the backlight is the same regardless of what color is being displayed. How much light is blocked or let though by the liquid crystal layer varies depending on their alignment (what color is being displayed). But this doesn't affect how bright the backlight is, anymore than pulling a window blind makes the sun burn less hydrogen.

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.

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.

Time to replace battery?

Hello XDA!
I'm here seeking for some advice.
I'm a happy owner of an LG G4 since November 2015.
Phone has been running great (minus boot-loop, now fixed, last September).
Recently I've been noticing battery drains much faster, with the same usage as usual.
I know battery life is a thing, but having never changed a battery, I'm not sure if that means it's time to replace it yet.
I've been using 'Accubattery' for a few days, and out of 3000mAh, it reports 1980mAh, 66% health. Voltage is pretty much always at 3/4 (above 4mV, the bars turns orange sometimes aswell. Not sure if that means something)
Having never used this app before, I wanted to have a second opinion about this result, before I spend money on a new battery.
Notes:
- Last week I decided to try Resurrection Remix, and battery has been going pretty great. Although I reverted back to stock due the lack of a proper camera app/loss of camera features.
- I've been testing various kernels these days. SimpleGX is the one I've been using for the longest, and the early days (months ago) battery life has been great with it. I still use SimpleGX, but battery life drains by 1% every 10 minutes the screen is on more or less.
- In the past, when I was still using the phone fully stock, it used to get really hot (once it even triggered the 'overheating' error). I heard heat could drastically reduce battery life, so maybe... Overheating hasn't been an issue since I started using SimpleGX.
Thanks in advance.

I think all of us LG G4 owners who had owned it for more than a year has been complaining of short bad battery life just like me, on Accubattery app my battery health is currently at 72% (2152 mah out of 3000 mah), like I get maximum 3.5 hours SOT , So I think it's best time for most people to buy a new battery but for me I'm used to a power bank. In few months time I can't wait to purchase an LG G6! I'm giving more time to the LG G4 because in few months time let's see if my battery health drops below 72% of health. Can't say if the battery used to the heat from the CPU specially while charging? That heat might have degraded the capacity of the battery Happy that the LG G6 has thermal pipes and a much better CPU SD 821 that might not heat the battery in long term use

It could be time. If you ever played games heavily like pokemon go or done anything in general which sustained heat long term, it will slowly kill your battery health. With that being said these batteries do tend to go bad pretty quick especially after around the 1 year mark. I personally opted for the power bear extended battery and and nothing but good to report since then. I highly would recommend going for a new battery. Easy and cheap solution

Not a fan of Pokemon Go, but while using it completely stock, it often went hot for long time.
It stopped only after I started using a custom kernel, but I'd say I spent about 6 months with that already.
Not a fan of those extended battery, mainly due the aesthetic factor, but that's more a personal thing.
I will be ordering a new battery soon (Aukey one). Thanks for the advice

Question Does the battery for A52s last for two days, as they say?

Hi,
I am about to buy a phone with a strong battery and not to be large,
What do you think, does the battery for this device last for two days, as they say?
What do you think about pixel 5a?
/Regards

The battery is pretty good. I get about 7h Sceen on Time on 120hz but no 5G
If you don’t use 120hz, You will probably get 8-9h
This is for normal use like Snapchat, YouTube, TikTok and very light gaming.
If you use your phone pretty normally, The battery is fine. But if you do some hard gaming, Charging Once per day is required.
Overall, No matter what this phone can get through one ful day of battery life. (Mostly)
My thoughts on the Pixel 5a is to wait for the Pixel 6a.

If you can plug it to charge every 2 days why can't you every day?
It goes through a day with no problem..

If you love incredible battery life, get a 6000mah device and optimize it. You can easily do 3 days+ with a super lean setup under moderate usage and 2 days under more active use (of course all depending on how you define active usage, if you plan on doing long video calls, games and have a bunch of background sync services and 5G on all the time, it pushes it)

Its battery life is good enough that I've set it to stop charging at 85% and only start charging again at 80%, as a means to preserve battery health/capacity for longer. It's still pretty great.

Is this a good result so far?
