So I've had my S20U for a while now (almost 3 months), yet today something odd happened. I called my gf with about 20% battery left, we talked for about 30 minutes, then I started using facebook while talkin to her (i was on my home wifi network not 4g) and after a bit it started to drain the battery VERY fast. When i mean fast, I mean i could see the % going down faster then 1% per minute, more like 1% every 30 sec. I decided to quit the call at 2% and few seconds after that the Samsung logo appeared and the phone totally went off, 0%.
Now I charged it back to 100% and after 2 hours of idle its at 98% which seems to be the usual drain while idle (1%) but what I'm wondering is... what the hell happened before? Have had every Galaxy out since S2 and i've never seen a battery drain like that before. I know when battery goes down very fast its usually a sign of a serious problem with battery, but this is a 3 months old phone... since i've had it i've never let it go below 15-20% since i know its bad to let it go that down and i usually start charging it at 20%, is it possible that maybe it was calibrated bad and thus it drained so fast?
Any other ideas? Thank you.
No clue?
- Are you using superfast charging? This will deteriorate the battery quicker.
- Never let the battery (if you can) drop below 20% & avoid charging above 85% , there is enough data available to show that charging between this 65% dynamic slows the battery wear cycle considerably.
- You called with 20% , while having WiFi on & scrolling Facebook (animations use GPU power , The display drains most the battery - WQHD by any chance?)
With the utmost respect this sounds normal particularly if you let the battery die & charge to full using 3amp power output

20% > 85% gives you 65% capacity, if the aim is to prevent battery wear, you've already just lost 35% anyway, defeats the point...
0>100% until the battery only holds 65% charge will give you way more life before you're stuck with 65% capacity, which would take years and years anyway
Not seen any data on super fast charging causing higher battery wear, I know its been a worry to people for a long time but no actual evidence, in fact I've read articles saying it does not.
Ok thanks for the replies but, let me make some points:
1 - S20U has a very fast charge for a reason. If it hurt the battery THAT bad, it would not be there. If Samsung put it there, it means they have done a lot of testing, and yes while I agree that after a year or so using it all the time you might stress the battery a bit more than with slow charge, for sure it doesnt happen after less than 3 months, and to the point of what i experienced.
2 - Again, whIile it is true that modern batteries are better kept between 20 and 80% (and its suggested when you, for example, decide to pull a battery out and keep it in a box), its also NOT true that not doing so will ruin your battery fast. I mean, your phone is made to be used, whats the point to charge it to only 80% and then have no power left during day when you're out and need it? Its just stupid. Everyone going out to work in the morning will charge it to 100%.
3 - Both 1 & 2 will help battery but thats something you'd see after a LONG TIME of using it, and the gain you see would be so little (probably about 10% ish over 20 months) that is really not even worth following those guidelines, its easier to replace the battery (or the phone, in my case, since I buy the newest model every year).
4 - What I experienced Is VERY different and for sure didnt happen for reason 1+2. And no, I always make calls while using Facebook and I've never seen the % go down that fast, like 1% every 30 sec like the other night. Something was draining the battery like I've never seen before in 9 years of Samsung Galaxy. And it happended below 20% so I'm not sure that has to do with it or not (in other words: if my phone was at 70%, would i still have had a drain so fast? who knows, maybe the problem was under 20% that was not calibrated right, but im not even sure this is possible, this is why i opened this topic).
5 - PS Most importantly: Ive never let it go below 15% since I've had it, and i probably charged it fast one time or two, i usually charge it wirless with slow recharge, so again, 1&2 makes even less sense in my case.
Ok update, it happened again. Was at 15% and i was on the phone while playing with facebook, after a while goes to 10% so i killed all tasks and shut down the screen and just talked on the phone, after less than a minute i turned screen on again to check % and was 1%. Went from 10% to 1% in about less than 60 seconds of screen off. Any idea what could be the problem?

Although it could be a battery issue as advised above I'd firstly try a factory reset and install all apps as new.
If this doesn't work a call/visit to Samsung may be the best option.

Sorry to say but your post does nothing to fix my problem (which is the reason why i started this thread) and only adds noise. Nobody said a battery is supposed to last forever. What we said is that you arent very smart if you buy a 1370 Euro phone and then charge it very slow all the time, keep it always between 20 and 80%, and never charge it to 100%, and all this to have the battery last a bit longer after 2 years. If you buy a 1370 Euro phone chances are that the next year you wont even have the same phone, and if you still have it after 2 years, 55 bucks for a new battery is nothing.
In other words, doing everything to preserve battery is just retarded, its a matter of cost vs gain, its just not worth. And telling people not tu use very fast charge because it will deteriorate battery quicker IS RETARDED, period. Because you assume that after a year the difference between a phone using always very fast charge, and using slow charge, is huge, meanwhile it isnt. The real problem with batteries is that they deteriorate over time no matter what. You could be super careful but still after 3 years your battery will be nowhere as good as it was when it was new, degrading it a bit with fast charge or charging to 100% makes very little difference in the big scheme of things. And people at accubattery are stupid, they tell us to stop charging the phone at 80%. Hello, I'm supposed to buy a 1370 Euro smartphone and leave home in the morning at 80% and be careful about what i do during the day because it could drain my battery and then go even below 20, or even totally run out since i started at 80%? Or maybe they think people buy a phone like that to use it while sittin their asses off on a chair playing on the pc and charging always between 20 and 80%? Come on, nosense at its best. You buy a phone to USE it. You buy an expensive smartphone to freaking use it as much as you can. Nobody at Apple tells iphone users "hey dont do this, dont do that, dont charge too many times, dont charge too little, bla bla".
PS if you're so worried about using the phone like you should do, dont install and save too much stuff in the internal memory, it'll wear out in the long run. hell, dont even use it too much, the screen itself isnt infinite.
I was on the 20%-80% bandwagon for a while, but just created more battery anxiety (hypervigilance about going below 20% and "overcharging" above 80%). I finally acknowledged that I never keep a phone long enough to see any real benefit of coddling the battery this way. Now I just use my phone how I want to use it, charge it when it needs to be charged, and don't obsess about long-term battery health. If I *do* keep a phone long enough to notice battery degradation, then I'll just replace the battery. The $100 or whatever it costs is worth not worrying about keeping the battery within some magical range.

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.

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.

The slow charging time was in an early 4.1.2 build. It has been fixed though already in a previous update.
I read they turned off the fast charge mode for it, I think in an effort to make the battery lifespan last longer.
I read that it slowly charges the battery on purpose. It allows the battery to last longer since it's not removable. Apparently the fast charge fries batteries pretty quick.

Fast charging a battery phone is not really going to fry it... but there is truth that if you slow charge a battery, it will last longer.
I had the HTC One on T-Mobile for a while before switching back to Verizon and it got through the day with moderate to heavy usage. Overall you should be able to get a day out of it at least

Did Verizon remove Power Saver from their model? I can't find a setting anywhere. I know that 4.2.2 removed it from the notification screen, but it's not under the battery settings either. Anybody know?

OK...My first full charge from 100%...the results???
I'm at 6% after 7 hrs 53 Mins
After a full days work (8 hrs) w/ my S4, I usually have about 65% left...I am hoping it will get better!

What was your screen on time? The only other reason I can think of that contributed to this was all the setting up, syncing, and downloading that you may have been doing on this first full charge (unless you did that all of that prior to this full charge)
Edit: Nonetheless, thanks for sharing. Hopefully it is indeed going to be much better than that on a regular basis.
It'll be a few weeks before I can tell if the phone's batter is any good. I'm spending a lot of time on it.

All I know is that in the first few days to a week of me having a new phone, I get horrible, HORRIBLE battery life. Why? Because it's shiny, it's new, it's interesting!
Give it a few days to a week and you will be back to mostly normal usage. I know that after the initial new phone excitement goes away, my battery life usually doubles.
Not to mention the battery cycle break in. I'm not sure if it's real or not, some people say it is, some say it isn't, but apparently it takes a few charge and discharge cycles for your battery to get to a normal state?

I read somewhere (pretty sure anandtech) that with these new batteries, it is advised against fully discharging. The optimal state is to charge it when it hits 75% ish.
If a battery dies, it dies, but you should not be purposefully killing it. I'll try to find the article, but I'm busy at work right now.

I don't know where you heard that, but for Lithium Ion batteries, over-discharging happens when you are around 2V or less... most phones will turn off when the battery gets to around 3.2V
Fully charged is roughly 4.2V
Most of these batteries are good for 250 to 400 charge cycles, It doesn't matter whether you are at 1% or 80%, the phone will stop charging once it gets to 100% since you cant trickle-charge Li-Ion batteries

Battery calibration anyone succeded?
Hi I have a battery calibration problem on my GT-N5110 Note 8.0 that I bought refurbished through amazon. I know it is the calibration since the battery usually drains pretty fast and when it gets to 1% it stays there for around half to one hour of continuous use. Also sometimes when I'm charging it, it jumps from around 60% to 100% and "charged" shows up right after that happens, when I unplug it and use it, then it goes down normally (fast) 1% at a time, even though that big jump while charging happened.
I have tried several "full cycles" without success and haven't been able to find a real way to calibrate the battery meter, neither here or on google, and since I didn't buy it in my country, local samsung support say they can not help me.
I'm on 4.2.2 leak rooted and the drain has been present since I was on 4.1.2 stock.
If someone can get a hold of how to calibrate, it would be really nice if you could share it! Thank you!

I tried the battery calibration app before, and really didn't do a thing for me...
I also suffer this weird battery behaviour with the device charging, it will take ages up to about 60%, and then instantly its at 100%
I also get this on the way down... when im using it, the battery drains fast, but when I get to 35 -40%, I then suddenly get the low battery 15% warning flash up, and then im all out of juice.
This is the same whether im on 4.1.2 or 4.2.2 custom or stock firmware
I rarely get more than an hour screen on time, and thats with fairly low brightness and power saving mode on
If someone could some how contact Samsung and ask them about the real calibration it would be very helpful for us having this issue... Since some don't live in the US and don't get the correct support :what:

Battery decreases so quickly when wifi is on! hardly get a days use out of it...:crying:
One method described in the battery performance thread which I've found effective:
"I wanna share my trial of battery calibration that really make a significant different at least till now .. I used to make calibration by discharge / charge cycles, but this time i add an official instruction of Apple:
- discharge the battery by ur normal usage till 1% then let the device play an HD movie till it shut down (that may take some time as it for me takes 4 hours!!) then turn it on to make sure the battery read 0% (my previous calibration the battery always shut down at 1% and I never see that 0% as I was discharging it vigorously) after making sure it is 0% it will turn off by itself anyway.
- now leave ur device turned off for extended time (about 5 hours or more is better according to apple "u could let it while u r sleeping"
- after that turn the device on and plug it in as it is on
- left it charges as it likes (for my trial it takes 7 hours and didn't say charged!! but I had to unplug it as I had to leave the work!)
till now my battery is really significantly improved, hoping to continue like that and I will keep u updated
Hope that helps :good:"
Discharging it completely, leaving it dead overnight then giving it a full charge by plugging in as a soon as it powers on has yielded good results for me. However I've also discovered a severe battery drain bug in stock Kitkat which has nothing to do with battery calibration; using wifi on certain routers causes Android OS wakelock which persists in deep sleep. I use my old Galaxy W as a hotspot for my Note 8 and consistently my battery drains overnight in deep sleep with wifi on. At my workplace we have a Linksys E2500 router, I leave the tablet on wifi throughout the day and don't notice the Android OS wakelock. So if you're having inexplicable battery drain test your Note 8 on different routers.

Calibration is a myth... google stated calibration tools do not help with how Android functions with battery management.
I posted my thread about battery and charging cables, and replied an a few topics like this one, yet nobody will search on Samsung DVFS disable or take note of it as being the cause.
Root with saferoot if you have not rooted, install xposed framework if not done so, and Wanam Xposed or Wanam DVFS disable. Since over 10 months now, my battery stats and performance are trouble free.
I was having severe battery drain for a while until I tried something I read about. What you do is carefully open the note up and disconnect the battery for about 15 minutes (they recommend a longer time but I don't see the need). Connect it back up and put the note back together.
It worked for me.
Google it, there's even a video on how to do it.
I was down to 3 hours or so of battery time but bought a replacement battery from a company called New Power 99. Cost $65-ish US and now I can go all day and still have at least 25% when I hit the sack at night. Huge improvement for me! I"m not a heavy user but I take notes at work, do some surfing, then read and surf alot at home at night. So far it's been great! Might think of a replacement battery. Probably cheaper one's out there but I wanted to get what I paid for so shelled out the extra.

Hi! Thanks for the info! That's great to hear, one question, did you change the battery yourself? If so, could you provide a hint on which guide you used, that would be verry helpful:good:
The battery came with a DVD that explained it (with really bad music) but the bottom line is you pry the back off, take the 8 screws off, unplug the old - plug in the new and replace everything. Not really hard but, as I said, nerve-wracking! I was afraid I'd screw it up but it was pretty straight forward.

Any time. Hope this works for you. It did for me.
I. Had the same issues, I just took off the back cover and disconnected the cable that connected the battery. I did not need a new battery. The toughest part for me was disconnecting the battery cable... I actually had to take out the 8 screws that held the battery in place, so I could get some leverage. I only had my battery disconnected for only 5 minutes and it solved the problem for me..... Good luck!

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.

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.

Hello. I bought my Mi 6 (Chinese ceramic model) in... January, I believed, maybe even February. The screen-on time from full charge used to be 12-13 hours with mostly web browsing and the occasional gaming. I guess it lowered somewhat throughout the first few months, but it was still quite high and usually over 10 hours. Now, Xiaomi released several OS updates in that time, and I suppose none improved battery life (even though I check user feedback before updating and occasionally that was a claimed improvement), but since the last update I think something went seriously wrong.
I'm not sure it became like this exactly after I updated to 10.0.1.0(OCAMIFH), which makes it even stranger, but currently my battery gives less than 3 hours screen-on time before shutting down. It also drains considerably when idle, possibly >10% over-night.
It doesn't seem right that the battery would age so quickly all of a sudden. The phone is less than a year old and the battery acts like it's 5. Is there anyone else who have it go this bad all of a sudden? Maybe something on my phone is spying on me and drains a ton of battery? Or perhaps the battery used in the Mi 6 is crap and loses capacity too quickly?
Thanks in advance.

you should check what is draining your battery (you can find it in the settings) and i would advice to do a "factory reset" as maybe after the update an app got "crazy" or dose/doze? isn't being "used", also there is an option on the app's settings page where you can select what type of "optimization" the phone does to conserve battery atm i have mine set to "let miui choose the best"
Hi! Did you for any chance bought a miband? I ask this because both me and my girlfriend have mi6 and I use the mifit app. I get around 3 or 4 hours screen on time per day while she gets 6 or 7.
Either way, don't think you should expect the 10 hours to be normal.

Nope, the phone isn't connected to any peripheral. I didn't think it should last 12+ hours (so even more than 10) for eternity, but to my understanding lithium ion batteries lose about 30% of their capacity after 1,000 recharging cycles, and I doubt I got even close to that in 10 months while my battery has supposedly already lost 50% or more than its original capacity.

I meant smartphones in general, because I always hear "lithium ion".

Lithium-ion and Lithium-polymer (mainly know as Lithium-polymer-ion) are identical, just their physical sizes change and some of their characteristics are a tiny bit different, nonetheless i get on my mi 6 like more then 10hours of battery life (browsing instagram, playing a few games here and there [somewhat high demanding], listening to music all the time) and i also charge mine from 67%~40%-25% and i have not seen any type of "degradation" on my battery, i would reccomend you to not charge it all the way to 100% (as a way to lessen the charge cycles, i mean even if you dont reach 100% the closer it gets to "full" the more strain you put into the battery, the same goes for reaching 0%) i would also advice you to do a factory reset, as usually it is an "app" that eats the entire battery life. ( sorry for my bad-ish english, hope i helped)
My mi6 is suffering from the same sh*t... Almost 2 years old. I was on miui eu for almost one year... Never updated...
Wanted to go back to something different.. tried RR OS 8.1 final and now Mokee 9.0 but they give me horrible battery life. I did a complete fresh install with erase data.. can't make it through one day. Maybe 2hrs SOT..[emoji26]
Last night it drained 11% within 7hrs in airplane mode [emoji848]
In settings it says: no data about battery usage ..
It really annoys me since i don't wanna miss the smoothness of that ROM...
Miui eu gave me Bluetooth problems with my car otherwise it was okay, especially battery wise...
Any suggestions?
Appreciate it!
Well, let's not transform this in a Lithium related topic.
The thing is I'm having the same problem as OP, and have seen many users in en.MIUI forum in the same situation. I'm now with latest global stable(V10.2.1.0.OCAMIXM), but even after that update i was on V10.0.1.0, never rooted, never unlocked bootloader, etc. I always had good battery life, even in v10.0.1.0. But one day, suddendly my phone started a huge battery drain.
No, it's not associated with any app installation, my usage routine didn't changed, everything was still the same as before, but a ramdom battery drain appeares, did u guys get it?
Just to record the gravity of the situation: overnight i lost 20%~35% of juice, this is ridiculous!
I though to myself: It must be a battery problem. Ordered a new original one and for my surprise the problem continues.
I don't now what to do, i don't want a custom rom not based on miui because i really like it. Is anyone using the latest miui.eu and have this battery drain?
