Hi guys, I usually lost about 3% overnight with 4G and power saving mode. But tonight a strange thing happened. For the first time, I got a huge battery drain. I leave the phone at 01:30 am with 25% and this morning I found it turned off. I think that is impossible to lose 25% over 7 hours, what could be happened? I would like to know if the fact that the battery has reached 0% and the phone shutted down can damage the battery.
I am a little bit worried since I read a lot about the fact that the battery never should reach 0% and the phone doesn't have to shutdown.

No it can't damage the battery. At least not if you charge it in the next few days. Here's the thing. The battery voltage should never reach under 2.5v. If this happen, the small chipset inside the battery will completely turn it off in order to prevent further loss of voltage. When this happens, the battery pins will be unresponsive, meaning that it can't provide electricity and can't get electricity either. It means you won't be able to charge it with your regular charger. At this point it's not even completely dead, but it would need some professional chargers to in order to revive it.
With that being said, your phone shuts down well before reaching 2.5v. Unless you leave the battery it at 0% for days (or probably weeks) you can still charge it and everything will be perfectly fine.

First, thank you for the explanation, I don't know so much things about batteries, but I do know that there are a lot of legends out there. Usually I charge my phone when I reach 4/5% not less. Is that a bad beavhiour? About my topic, like I said this is the very first time that the battery completely discharge and the phone obviously shut itself down. When I woke up I putted the phone into charge immediately. I just hope that it's all ok, but I don't understand how it is possible to drain 25% of battery over 7 hours or less.

It doesn't really matter for Lithium-Ion batteries. It's not bad, but it's not good either. Use the way you like it. There's no harm in charging it to 100% every time you see it under 50%. There's no harm if you don't charge it from 0 to 70% either. It really doesn't matter. The worst thing that can potentially happen is to get some odd numbers for the remaining charge. Like having 80% and in just 2 minutes to have 76%. The capacity of the battery will be the same, it will last the same, only the indicator might be a little inaccurate. If you ever notice this, do a full cycle. Discharge it to 0% (let the phone shut-down), charge it to 100% and that's it. It will show accurate readings again.
But you don't have to do that constantly. Only if notice wrong readings.

Until now i didn't saw any wrong readings, except from 100% to about 94/95% where the battery drop faster. Except that i often let the battery reach 4/5%, but if it is not good i will charge it when it reach max 10%. About the 0% question i hope that this will not happen again and that the battery keeps its complete functionality after this episode
Don't worry, it's good. Li-Ion batteries are way more durable than the old Li-Pol batteries.
I hope so Thank you.
I had 37% battery drained overnight and wondered why...I turned off google photos backup and now is fine. I still lost about 9% overnight but it isn;t too bad as I get a lot of notifications through the night

In my case my phone drains about 3/4% overnight, but like i said this morning i found it turned off and i leave it with 25% of charge. Very weird, i don't have an explanation yet.

About that, i read some topic on other forums where people says that is very bad discharge the phone until 4/5% and they says that the correct thing to do should be to discharge the phone when it reach 40% of charge, because under that percentage the battery's life became shorter. This seems really strange to me.

So I thought this was a fluke the first time then I was just able to reproduce the issue again. Once the battery level reaches 20%, the tablet will either shut itself down using the built in shutdown command or will just simply power off as if it doesn't have any power left at all.
I've charged it thoroughly and have even drained the battery down to 1% in the past but this keeps happening now. Any ideas?

this hasn't happend on my nexus yet but something similar happened to my LG Nitro HD. I basically rooted it and tried some battery calibrating apps on the Play store. In custom recoveries there's also this option to wipe batter status which i think might fix it but i've never tried it.
The battery gauge can be quite inaccurate. From what I have seen, I think Asus cut some corners in calibrating it for the specific battery chemistry - which makes things even worse.

It's not as if, there is no power left. The battery gauge simply had a wrong estimate of the remaining charge and suddenly the battery voltage collapses (happens very quickly towards the end of the discharge curve) and the N7 shuts down.
Messing with the battery stats doesn't do anything useful.
If you do a full charge / discharge cycle that may help a little with battery gauge accuracy. The battery gauge does some recalibration when doing that.
After a forced shutdown, fully charge and make sure the tablet sits around fully charged for at least 1h (e.g. just plugging it in over night will do fine). Then do a full discharge cycle with the N7 not plugged in at any time (normal usage will do just fine).
Those battery calibration apps don't anything useful, beyond getting you to run a full charge / discharge cycle.
Never happened on my Nexus 7, which have been taken down to 14% more than 10 times in the last 2 month. If what are suggested above don't work then use this tool to restore stock then Warranty return it or return it to store if you still have time,
Wonder if this is what happened to me last night. Was watching a video and it just shut off like the battery was dead. I wasn't paying attention to the battery but was almost positive it wasn't anywhere near zero yet. Never had the low battery pop up on me either. Hopefully it was a fluke...
there are many battery calibration issues/posts in old N7 forums. it also happened to me once in first couple weeks. what helped, I think, was shutting down the device completely with a little bit of battery left and just keep it unplugged for a few hours. Some say to preventively repeat this exercise every now and then..

I had tried completely discharging it and then leaving it to charge overnight a handful of times without any luck. I ended up just restoring it to factory state and getting a replacement via Google Play Warranty Support. The new unit works just fine. It's an 07/2013 build unit just like the first one if anyone was interested.
by any chance do you use a qi wireless charger?
I have encountered a weird bug where if I charge my nexus 7 with a qi charger to 100% and leave it on the charger itll screw up the percentage/battery stats. with my situation, itll lock my battery % to 100% and wont go down until i go into twrp. If i just go into twrp and not recalibrate the battery stats, the percentage would be off and my nexus wont show the right %, so my nexus would shut off at random % instead of the normal 1% or 0.

Did help on many devices for me with battery calibration erros...
Last one was a Galaxy S2 last weekend - turned of immediately, showed 0% upon start.
Took battery out for 4 hours, put it back in then and voila... 92% and everythings fine again.

hi guys,
I have noticed that when i unplug the phone from the AC power, without doing anything particular, the battery seems to drain rather fast from 100% to say 93-96% then after that it's very good and i can see in the battery graph that it goes much flatter and i can usually do 3 days before having to recharge which is great.
my only question is, does the phone "do" something special in that first 6-8% of the battery usage? I have gmail sync, calendar sync and I am not a heavy user overall.
thanks,
Gab
It's probably just an inaccurate calibration / reading, mine does something similar
Soon as I unplug, some days it stays at 100% for quite a while, other days it drops to 99% instantly, quickly down to around 96% like you say, then levels out

Interesting, maybe i will let it go really down like 5% then charge but otherwise might be normal.

They suggest once a month to completely discharge the battery and fully recharge again
The batteries themselves do not suffer from that old memory issue the old batteries used to, but the phone calibration starts thinking that 20% is 0% if you always charge it at 20%, so you need to fully discharge to calibrate
Same reason they say to charge first ever charge for 12 or 24 hours or whatever it is, even though the battery is full, just to allow the phone to calibrate
Try the battery calibration app from the play store, especially when coming from a different rom
So excited about getting my new phone today but have a question prior to opening just to be prepared. What is the best process to ensure the battery health when first opening device? Do I charge the device fully prior to turning it on for the first time or do I let the battery drain fully before I put it on the charger? I know this is an age old discussion but not sure with these new phones how to best handle it.
Thanks in advance.
I honestly used it took it died, then I charged it all the way to 100 (never leave overnight) then I let it die all the way, then charge again.. So far good battery life
That was after my first full charge[emoji4]

That is the worst thing you can do. These aren't NiCads. LiIon batteries do not like to be fully discharged.
You'll likely find that the battery will be charged to roughly 40%. This is considered the ideal amount of charge for long-term storage. People often still worry about memory effects of batteries, harping back to the days of older battery types such as Ni-Cad and some Ni-Mh batteries but the same isn't true for Li-ion or Li-Pol batteries.
The one thing to absolutely try to avoid is letting the battery run down to flat. Li-ion batteries will degrade quicker over time if discharged fully, which is also why devices have a built-in "buffer" amount when you run the battery down to avoid damaging them.
Honestly, the main issue for your battery is heat, and large drops or knocks. Try and keep it cool and never let it die on you!
You don't need to do anything special, just use it. One thing you should definitely not do is completely discharge the battery though. You should also refrain from keeping the device connected to a charger once it's reached full charge, keeping the battery at peak voltage decreases the long-term battery life. Here's a couple of really helpful articles:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
http://batteryuniversity.com/learn/article/do_and_dont_battery_table
Just a point of info: Phone batteries don't LET you completely discharge. Once your phone shuts down (afer running "out" of battery, the battery still has some level of charge left.

That is right, but if you continue to power the device on in order to drain it more you'll cause problems. It's virtually impossible to completely drain one of these batteries, it actually powers down at something like 50% of its true capacity, because if it gets much lower than this it can cause irreparable damage. If you do somehow manage to drain one of these batteries past that magical point (by the methods I described above), it will simply not power on again because there's a minimum amount of voltage required.
Interesting. I normally charge my devices while I sleep so when I wake up they are fully charged. Once I'm up I'm ready to go and have a full charge not wake up to charge the device and wait for it to reach capacity idk. I haven't had any issues in any phone I've had while charging it while I sleep at night

It just basically reduces the capacity of the battery over time. I charge in the evening before bed, it only drops a couple of percent overnight thanks to doze.

With my Nexus like now I'm in bed with 77% battery, I'm usually on my device until I fall asleep, my BlackBerry has great standby time. With doze, I don't lose much battery if any and since the phone recharges so fast. I'm rarely "dead" enough to warrant me charging it while I sleep like say my note four etc. But this is food for thought in regards to charging

Hi everyone, i've ordered a new battery (Polarcell 2900mah) and i should receive it this week...i saw somewhere that android does not really read the battery percentage, but instead estimate it. I also read about battery recalibration or initialization which is fundamental for android to proper estimate the actual power contained in the battery, but i'm a little bit confused anyway...since i want my new battery to work proper and last as long as it could, do someone among you know about this fact? Is there any guide? I can't find anything.
P.S. i have a I9505 (jfltexx) and i'm actually on RR v5.6.3...so android 6.0.1
That is complete BS.
I never "calibrated" mine.
PS: most calibration apps do the same thing, and that is to delete a file that has no connection with the battery percentage. This was stated by a Google engineer.
Batteries should come charged at 50%
That's the perfect storage charge.
If there was any calibration method, then it would be: let it discharge completely, then recharge it to 100%.
Another note, valid for Li-on batteries: The deeper the discharge the shorter its life will be. In other words, if you let it discharge as low as 20%, or lower, every day, the battery life (before it needs replacing again) will be shorter.
Another thing: Leaving the battery at 100% charge for extended periods can also damage its ability to hold a charge for a longer time.

I'm not talking about fabulous apps which do magic things...i mean, as i read, there should be some cycles of charge and discharge which nave to be done, not for the battery, but for android, in order to really manage the power in the battery, without those 20% from 100% to 80% dropping like stones. Sorry for my bad english, i hope i explained myself.

No it's complete crap. Android does that perfectly fine. There is really nothing you need to do.
That only applied to phones 4 years ago. You never need to calibrate it anymore.

As I said, I never calibrated mine and it works.
That whole "Let it discharge completely and then charge it over night" is just a left-over from the old batteries. Those new kind of batteries don't need that.
Those batteries aren't ment to stay at full charge all the time. That is the reason for the fast drop. Mine drops for 100% to 99% in the first 5 minutes. And it drops like that until it stabilizes at around 94%.
The moment your battery needs calibration is when the phone shows 30% left and it suddenly turns off. That means it shows a wrong percentage, or that the battery needs to be replaced.
OK, then i'll just swap that battery and use the phone normally...thank you all
lithium batteries don't want to be left fully charged or fully discharged for too long. it damages the poles if that's the right way to say it. so outside of that just follow what your new battery makers recommendations
Do you let your battery drop down to 5% before connecting the charger? Or do you charge every moment you get the chance to keep battery at max?

I'm not an expert, but all I've heard is charging over night or after it hits 100% is bad. Why I don't know, but I try to charge my phone when it reaches everywhere from 15-30 to 95-100 then remove the charger.

I'm not constantly on my phone, so usually charge it up to 80% and recharge when it drops to 40%. I only charge it to 100% when I am out and about for the whole day. See the following link for charging advice:

Nah, that's old news. Modern chargers and devices know when they've hit 100%, so they stop charging at that point and lets the battery dip down to 98-99% before trickle charging up to 100 again, and so on until you unplug. It's completely safe, and you shouldn't trust all those garbage click-bait articles out there. Do not, however, go down to 0% before you recharge it. That can actually damage the cells in your battery, so plug it into the charger before that. If you notice some funky behavior from the battery, like if it's jumping from 30% to 20% in five minutes, or is stuck at 10% for an hour, then it's a good idea to completely drain it to 0% to calibrate the battery since the OS has no idea how much battery is left (so it knows where 0 is again). This will usually happen after flashing a different ROM. Charge it up to 100 again and it should be back to normal.
I personally charge it normally at night, without quick charge, since there's no point in having it quick charge while I'm a sleep for around 8 hours. I'll only quick charge it in the middle of the day, which is almost never, since the battery is freakin' awesome.
Don't worry about the battery too much, but don't reach 0% too often, and you'll be good. By too often, I mean every 3-4 months or so is OK. I base these things from my Sony device which I've had for almost 3 years. The (sealed in) battery was very good out-of-the-box, and it's still very good after nearly three years, so I won't mess with a proven success.
To be safe on the longevity of the battery I use one of these with my wireless charger :
http://www.amazon.com/gp/aw/d/B003P...mer+outlet&dpPl=1&dpID=31OAEbif0lL&ref=plSrch
My battery is usually around 30-40% at the end of the day. I use the regular speed Samsung Charging Pad and set the timer on this outlet for 3 hours when I go to bed. So after 3 hours it stops charging and I don't have to worry about the possibility of damaging the battery (I know about trickle charging, but I think this is better)
Ive read somewhere that the new s7 edge charger doesnt have a power inverter so it keeps charging and wasting power which could damage the charger or possibly device. So know if thats correct.

I just purchased one of those...thanks for the advice. I charge my device when get around 20%-30% of battery and left charging over night ( when sleeping) on my standard Samsung wireless charging. My battery is just ok.. I'm not so heavy user and sometimes I have to charge around 8pm or so. I take off from the charger at 100% all morning around 8am.

At home. I do wireless when ever i can. If im not using the phone then i sit it on a wireless charger.
Battery hasnt drop pass 30% in the week i had the phone.
My note edge would drop pretty low because i didnt use wireless charging. So my phone would just sit in my pocket slowly draining.

Whatever you read, either you misunderstood, or the person that typed it was a bumbling idiot. A power inverter converts DC power to AC. Your source/utility power is already AC. A USB charger is merely an AC adapter made for USB. The phone has integrated circuitry that controls when and when not to charge the battery and at what amperage.
I usually let mine get to around 5% everytime. Then charge it back fully to 100%.

Nah, that's old news. Modern chargers and devices know when they've hit 100%, so they stop charging at that point and lets the battery dip down to 98-99% before trickle charging up to 100 again, and so on until you unplug. It's completely safe, and you shouldn't trust all those garbage click-bait articles out there. Do not, however, go down to 0% before you recharge it. That can actually damage the cells in your battery, so plug it into the charger before that. If you notice some funky behavior from the battery, like if it's jumping from 30% to 20% in five minutes, or is stuck at 10% for an hour, then it's a good idea to completely drain it to 0% to calibrate the battery since the OS has no idea how much battery is left (so it knows where 0 is again). This will usually happen after flashing a different ROM. Charge it up to 100 again and it should be back to normal.
I personally charge it normally at night, without quick charge, since there's no point in having it quick charge while I'm a sleep for around 8 hours. I'll only quick charge it in the middle of the day, which is almost never, since the battery is freakin' awesome.
Don't worry about the battery too much, but don't reach 0% too often, and you'll be good. By too often, I mean every 3-4 months or so is OK. I base these things from my Sony device which I've had for almost 3 years. The (sealed in) battery was very good out-of-the-box, and it's still very good after nearly three years, so I won't mess with a proven success.

Thanks for the details information. I figured the technology is so advanced with batteries that overcharging is in the past.

I reach 5% max, is it a problem for the battery's life?

Not at all, but just try to not discharge the battery completely to the point where it turns itself off. It won't ruin the battery to the point where you actually notice it there, but it's better if you just turn the phone off if you're able to (unless it's an emergency, of course).

I never discharge the battery completely, like I said I use until battery is max at 5% [emoji3]
Sended from my Samsung Galaxy S7 Edge Gold Platinum
I charge it when it hits 20%. But i dont use the fast charging unless i need a quick top up
Does it hurt the battery to charge the phone with a different charger ?

I never used the fast charging, I think that slowly charging a battery is better for the lifetime. Most of the time it is below 10 % before I plug it in and I also want it to be at 100% and ready (green LED) when I unplug it.
my note 3 battery is still superb and I got the phone since 2013
Best way to keep a battery in good health is to charge it to full before you start using it. Also, try and never charge it until it's less than 50%. Charging it overnight is perfectly fine it won't hurt anything but once ina while, at least say once a month let the battery drain all the way, try to turn it back on if it goes off sometimes there is still some juice left and it might start up, once it won't start anymore try and charge it without turning it on to full. I wouldn't do it more than say a couple times a month any more than that is overkill and may do more harm than good. These are the guidelines I use and I have never had battery issues. I currently am waiting for my S7 Edge and on my Nexus 6 I usually get 48+ hours with 4+ hours SoT. I'm just an average user currently.
