Could someone please develop a good app that would enable the battery to be drained as much as possible and to charge slower so we could all properly calibrate our batteries?
Do we really need this since it's a Li-ion battery? I know Ni-Mh and Ni-Cad has memory effect, but not on the Li-Ion battery.
I was just wondering the same thing today....simply because there seems to be several different methods to do it. Some say charge 8 hours, turn off, charge and hour, unplug, turn on charge 10 minutes. Then other methods say to do something different....be nice to have an app to walk you through different methods so you know step by step your doing it right
I calibrated mine last night and I'm going to get about 18 hours if not more from it....before yesterday I was getting 9.
The ONLY other different I did was make some profiles on CPU but I cant imagine it would make that much of a difference. I bet its a mix of both

That is to funny I was just saying to my wife the other day that I should make one of these programs seeing that there are none already. I hate having to manually kill my battery every night before I charge it again.
Is it needed? It depends on your school of thought, some say yes, some say no. All I know is that on the few devices I have had in the past, if I constantly plug them in to "top them off" then the battery never ends up lasting very long after a few months of doing that. So I am a believer in killing the battery before charging on devices like these.
So the bottom line is if there is a desire for this, I may try to put an app together for it, as I know myself I am interested I just didn't think many others would be.
All the battery calibration tools, are basically deleting the file... right?
Is it that hard to boot into recovery and wipe battery stats?

I think the second part has to do with hardware. The phones hardware just doesn't have trickle charge implemented and instead lets it drop back down to 90% then starts charging it again.
As for the second part, it came on our phones, even has a default widget. 4G

Um... actually that is (by most accounts) bad for Li-Ion. You want to AVOID completely draining them. All of this stuff is more art than science, but I have way more often heard that completely draining LI batteries is bad. What kills them is the number of cycles they have been through (like -25 +25, -25 +25, -50 +50 would be a full cycle).
You do however want to give them a full up down cycle once in a while (maybe every 1-3 months) for calibration.
Then again, as I said, it is more art than science, and I have heard your method as being better, but the not draining argument seems to be the vast majority.
I'll try to do a little look-see and update this or repost if I find any stronger evidence.
the thing about my phone and battery that ALWAYS baffled me was i would plug it in at night be it at 10% or 22 i would leave plugged in while slept i would wake up unplug and look at battery percentage and it would be like 95.....no other phone has even unplugged and dropped 5 percent by doing nothing????
turn your brightness to 100% and change it so that it never turns off; use wifi tether and play a 720p movie at the same time; oc your kernel to it's highest stable frequency. it'll drain pretty quickly.
I know I might get flamed for this....
Apple suggests, with their laptops, to once a month or so, run the battery completely down. Then let the battery cool down for a little bit. Then give it a full, uninterrupted, overnight charge. I forget if they said to repeat this a second time, then you're good.
This is all from memory of me reading this a couple years ago or so, so our might not be verbatim. Their laptops use lithium ion technology...
(and they used to blow up and melt down too!) Lol!

That's because the phone stops charging when it reaches 100%, and runs off of battery probably until it reaches in the low 90s, then charges again. You won't ever notice this because the light will always be green. However, you'll notice that unplugging it a few moments after it turns green, the battery will stay anywhere from 100%-98% for a while. At least on my phone it does.
Is there any way to make this program "auto run" during sleep so it can do everything it needs to do during the night charge (similar to quickpull for blackberry)

I am by no means an expert so if you find any reliable info on this and can link us to read, I would love to learn more. All I know is that it is commonly said to drain rechargeable batteries and that I have seen that topping them off very often does lead to battery life degradation.

There is no need to fully drain the battery. Its purpose in calibration is to configure the software that is correlating voltage to percentage charged. That's all. Regarding the old Apple advice, that is doing the same thing. It will not affect the hardware.
Now, what WILL affect the hardware is charging itself. Every charge/discharge cycle will reduce the total capacity of the battery. This is why the EVO will not cycle on it's own until 10% discharged. It's improving the overall battery life by that restriction.
In short, you will save money overall by getting a higher capacity battery that you don't force to charge too often. Draining your battery does nothing but give you peace of mind and it only really needs recalibrating when it's total capacity has been reduced which isn't often. 3-6 months.

I'm interested!
Btw - what are the charging calibrations people are using? Are you seeing one working better than another?
Im a noob, so take what I say worth a grain of salt but yesterday I did the standard method where you fully charge...turn off...plug back in until led changes green and do it a few times.
I went from 9 hours to 17 hours with no other changes except a few profiles in setCPU.
I did this just last night so my results are fresh.

A few SetCPU profiles is all it takes to see a dramatic increase in battery life, especially while screen off. If you disable it I bet whatever gain you think was from 'calibrating' it disappears.
Waiting to get my hands on my DHD at Sunday when I return home from my girlfriend. Im just curious if I need to charge it those 12ish hours like I've always done when I've got a new phone, or if batteries is different since my last one.
Thanks!
a full recommended charge by manufacturers is usually 12 - 16 hours, so charge it for 16 hours and then have some fun...

Does that also count for todays smartphones? I mean, I know all Apple Products comes precharged so you dont have to bother with the 12 hours of charging. HTC aint running that path?
I quote a message I've made in the battery life thread:
theboostman said:
Since i use some RC Helicopter with li-po/li-ion that both have the same way to produce energy, I have learned how to use this kind of battery and how to ensure a good battery life/durability.
There is no reason to worry about the battery if you follow those few recommendation (given by a battery producer):
-Your battery has to be charged with a current of 1C max (1C mean 1230mA for a 1230mAh capacity).
-Your battery voltage must not be over 4250mV. If you go over, you may damage the battery and risk random explosion/fire. In normal use, it's better to not go over 4200mV.
If you charge the battery with your phone, you will never be able to go over 4200mV because the charge stop automatically before.
-Your battery must not be under 3300mV. Same risk as above. In normal use, it is better to not go under 3450-3500mV to ensure a good battery durability (numbers of cycle charge/decharge). I think the phone show 0% at near of 3450mV, but never check this cause i never wait my phone to be as close to the death.
-Your battery has to be drain at a current of 10C max, i.e for desire HD , 12.30A (1230mAh x 10).
impossible to reach that current with your smartphone so no worries about burning your cpu with heavy bench.
Whatever you do respecting this will not be harmful for your battery.

So don't believe crazy rumor and just follow battery manufacturer recommendations.
charge the phone up to full for first time is just usefull to ensure a good calibration of the battery level in android.
But the battery itself doesn't care about first charging since they already have been charged for the stockage by the manufacturer.
You can check with Currentwidget the current send to the battery. Wait until you have 0mA. This can take 1h after the green light has turn on as the green light seems to occur by voltage mesure and not by current.
this occur every time you charge the battery and then I prefer to check with Currentwidget when the battery is actually full.
It is good to know here that a li-ion battery will reach near than 4200mV before to be full and at this state has to be charged with a current limited Alim. It seems that this is already used by the phone as you can see the current decrease as long you reach full charge.
But as I already mention, it seems that the phone show 100% when a voltage Value is reach. So it is not very accurate to see when the battery is actually full.
After that you can play whatever you want with your battery:
- You don't have to wait that the battery is full discharged to charge. ( In fact it is better to never wait your battery to be empty)
- You can stop the charge before the end.
- You can leave the phone plugged in the whole night cause the phone automatically stop the charge.
Can you use the phone on the first charge?
Yes you can. For battery point of view, no problem.
For android battery level, I don't know if using the phone at first charge can cause more inaccurate mesure but anyway the battery level will be more accurate after some cycle of charge/decharge so don't care about this. Plug the phone and use it!
Very, very detailed. Far more detailed than what I can understand. I'd follow the battery manufacturer recommendations, but HTC doesn't list anything helpful on their website.
The battery is partially charged when shipped. Before you turn on and start using your phone, it is recommended that you charge the battery.

..they dont tell you if to charge until simply fully charged, or 12ish hours. Thing is, I read in another topic that the whole point of charging for a long time was back in the "NiCad days"; but does not apply for Li-ion batteries.
Can this be confirmed?
To be more clear:
- optional(but recommended): Charge the battery up to full at first time (about 3h, check with current widget for example)
- never let your battery be empty
- each time you charge, you may charge about 45-60min more when the green light turn on. (you can check with currentwidget or equivalent when the battery is actually fully charged)

Thank you very much. : )
So I simply use CurrentWidget (by which looking on google shows the current mA) and simply waits till it hits 1230mA. Is that how the widget works? If yes, after reaching 1230mA, do I still leave it in for 45-60mins or not?
Sorry if im not getting it right - getting into Android is not as easy as I thought it would be.
No that's not right
Current widget will show you the actual mA consumed by your battery when the phone is un plugged and the actual mA sended to your battery when charging.
This allow you to check when the battery is full.
When you just plug your phone, you will see battery widget show about 500mA and then decrease down to 0mA as long you reach full charge.
When you see 0mA, the battery is full.
You will notice that the green light and 100% status are reached before current widget show 0mA.
This is why you can't trust the green light when charging your phone and have to charge it 45-60 min more when the 100% status/green light is reach

Oh!!! I get it now! THANK YOU!
Guess I'm just gonna have to deal with turning it on and getting the app. - but probably shoulnd't affect it in any way (the battery that is...) ^- ^
im picking up my new phone tonight then heading out for dinner
i dont think im going to be able to sit there and not turn the thing on and have a play with it
from reading the posts here it sounds like doing so wont cause any damage to the battery it might just screw up the android battery readout
on my galaxy s you could boot into the recovery menu and just wipe the battery memory
cant i just do that with this phone ??
I wouldn't risk it. Wait till you get home, turn it on, download Current Widget also mentioned in this topic, plug in the charger and wait for the app. to show "0mA".
I also couldn't resist turning mine on and ended up with dust on the wrong side of the screen (yes, theres a tiny gap around the screen where it crawls in - lame design) - now im going down for a swap and I wont open the box until I recieved my case for the back and shield for the front+lens.
I'd suggest you to do the same to avoid the damn dust and scratches. Its up to you tho.

Yea, it's not easy to keep the hands off it.
I dont know if it's gonna "damage" it and cause a worse battery life, but it's full potential will first show after a few recharges apparently, it's up to you. Hopefully your cover will actually cover the gaps from dust etc. (unless ofc it's a full-case cover.)

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?

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.

Pretty good link, thanks. And reinforces what I just said above.
Most any smartphone or tablet made in the past several years uses a Li ion battery. This confirms it: http://www.gsmarena.com/samsung_galaxy_note_8_0_n5100-5252.php

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?

dumbest thing wrote in this thread probably. You do not need to train or do a full charge. How come people still believe that nonsense in 2013 ??

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.

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

Only four hours? My Nexus 7 averages about 10.5 hours of Netflix with 10% left. I wonder how other note 8's compare?

Hey everyone,
The battery life for stock on this device is superb. People love to see how much they can get it out of it. Good for you. I've been there.
If you want to maintain higher battery capacity over time, and reduce the chance of your battery from failing, then read on...
I stumbled across an app on XDA called Battery Charge Limiter (https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002) and wanted to bring it up on here.
In short, it lets you limit the max % your device will charge to. This in effect saves cells in your battery and prolongs its life. This is proven. There are several reasons for this, but I'm not going to go into it. If you want, you can look into it at Battery University (the link is in the OP for the app).
MY EXPERIENCE
I have been using the app for about a week now, and I have had no problems with it. The default settings work perfectly with the Le Pro 3.
HOWEVER, if you are running stock you must allow the app to autorun and protect it from cleanup in the "Phone Manager". Otherwise you will need to manually start the app when you charge your device.
I have my device charge limited to 80%. I am easily getting a full day out of that charge (browsing, calls, SMS, and C.A.T.S gaming), usually charging once I hit around 25-40%.
I'm sure some of you will find this helpful. Feel free to click thanks so I feel good about myself :victory:
Cheers! :good:
I usually look for evidence like battery usage screenshot? A full-day usage should show something like 7-8 hours SOT with at least 2000mAh consumption.
It would also be better to charge the phone with a normal charger if you want the battery to last.
Normal charge when you are in no rush and the phone is sitting idle, Quick charge when its needed.
Personally, I couldn't be bothered as I change my phone every 8-10 months. Now waiting for Oneplus 5.

I'll take a look at my battery usage. However, I'm definitely not looking at the screen for 7-8 hours before I charge again. If you typically spend that much time on your phone (before charging again) then you'll probably need to fully charge it and drain it almost empty. If that is the case, then what I'm suggesting to do here is not for you.
Hi;
From JerryRigEverything's Teardown video I can tell that is not easy to replace the battery on the G7 plus if would void the water resistance and since I'll keep this phone for at least 2 years I have the following question about how to preserve the battery in the best conditions possible:
In order prevent the battery degradation, is it better to use: Fast or Wireless Charger?
Do you have any other advice regarding this topic?
3000 mAh isn't that great to begin with and if you add that it could get worse over time then it's better to take precautions. I wouldn't care that much if replacing the battery wasn't that hard. I mean it would require a good technician in order to get a proper reparation and I'm not sure I know one.
I apologize for the spelling or grammar mistakes, I'm not a native speaker and I'm still learning.
Charge whenever you can and dont let it go under 50%
The more you discharge it the chorter lifespan it get
Disable all crap you do not use.. When at home, and phone not used much. Turn off Wifi, BT, Location and even Data..

According to what I've read. I think the ideal scenario would be mantaining the battery charge between 20% and 80%.

Yes. That's exactly what I do with every smartphone I've own. I usually go heave on optimization of every single aspect regarding performance and battery life.
I use WIFI on, Data off, BT off, location off, auto brightness setting, Always on display off, no facial unlock, WhatsApp tweak to get only important notifications, the display is set down to 1080p instead of 1440p. When I play PUBG mobile I turn on Airplain mode and plug in headphones.
I purchased Acubattery. It has alarms that let you know if you are overcharged (more than 80% it says).
It also does a really good job of monitoring your current capacity and giving your hints on what is draining your device during the day. It will estimate your current battery capacity, which is nice if your phone shows they battery condition as Good (whatever that means Huawei Nexus p6).
Basically your battery is going to self destruct, but I find this app really gives you a good amount of information to make good decisions about how you use your phone.
I disagree with every advice here!
Check out my thread from my last phone :
https://forum.xda-developers.com/xz...ry-restore-t3796461/post76653346#post76653346
Been reading dozen of threads on diffrent forums regarding people complaining about their poor battery health, performance, etc.
Here are my advices to obtain near 100% battery health as years passes by (I have an galaxy s3 from 2012 with 90% and an LG g3 dual sim from 2014 with 92% ???), it all has to do with user behavior:
1. Avoid not charging to at least 95% then discharging it to near 0% (example: you charge it from 0 to 50 then you go outside and discharge it to near 0)
2. Avoid high usage for more than 3 consecutive days.
3. Drain SLOWLY from 100 to 0 once a week. This drain must be done at least in 1,5 - 2 days.
4. Charge from 0 to 100 with phone off at least 1 time / week
5. Every 2 weeks Let the phone discharge in 2-3 days, with minimal use, like just calling.
6. Repeat nr. 3 as much as you can
7. Avoid putting to charge when the phone is hot.
8. Avoid charging while using the phone.
9. Avoid fast charging.
10. From 100 to 70 and from 30 to 10 go slowly.
11. Never let it discharged 5, 10, 20 % more than 1 day
12. Never charge from 20, 30 to 100.
And many more will come.
Cheers.

There are so many things that could affect your battery life over a 2yr period. I own both the G6 and G7 and the G6 still gives me pretty good standby and SOT after 2yrs.
General rule says you avoid fast charging wherever possible as this will affect battery over the long run. Avoid scenarios wherein the battery might overheat.
Also little things like simply living in an area with bad coverage will eat through your battery like nothing else.
If your worried about battery replacement, im fairly sure LG service centres do it for a pretty resonable price anyways.
