So guys i just bought this phone few days ago, and the first charge was only untill 96% and then i unplugged it, because its take too long... is this can cause some problem to my battery? or is it still safe??

Did you use the original charger and cable? Of you don't use those you'll experience slow charging. Charging only to 96% won't have any bad effects on your battery.

so youre saying that my battery is still normal?
and btw yeah i use the original cable and charger, now i can charged to 100% after i let my phone die (0%) and then charge it uninterrupted overnight (like about 6hours)
thank you for the answer!

Yes the battery should be perfectly ok. Sometimes the calibration can be a bit off but you've charged to 100% now it's all good.
I don't think charging your phone to 96% or whatever will cause any damage to your battery and why would it?

hey i have another question, this thing have been in my head for a while now i just wanted to make it clear for me
for example i have 80% of battery then charged it untill 85% and then unplugged it and use it for a while until drop to lets say 80% again, and then charged it again to 85%
is that also safe to do?
i just did that when unlocking bootloader and installing twrp recovery, seems like my battery been draining pretty fast after that..
sorry if this noob question annoy you, i just want to make it clear

That's perfectly fine with a lithium battery. Small top-up changes are actually preferred. It isn't recommended you let the phone fully discharge very often, it also isn't recommended to keep it at peak voltage (100%) for very long (try not to charge overnight). A lithium battery is at its healthiest within the 40%-80% range. So yeah, top-up charges are perfectly fine. About every 30-40 charge cycles (roughly once a month is fine) you should do a calibration by discharging almost fully (from 100%), then charging back to 100%.

I've always said this simple statement about LiIon: Charge early and often.
Do you need to plug the phone in every time you get off a call? No. Do you need to worry about it dropping below 80%? No. Just charge as often as is convenient. Sitting at a desk for a hour working on something? Charge. Driving for more than 15m? Charge.
I think if you obsess too much you might wind up with USB connector problems from all the cycles on the connector itself, but intelligent use of the above statement should get you the most out of your battery.

No offence but I always found this to be stupid reasoning.
What if you leave home with a quarter full battery and you get caught in the middle of a natural disaster (earthquake as an extreme example) and need to keep in contact with rescuers after being stuck in a building for 2 days?
Personally, I always charge my phone/laptop whenever convenient.
black50z said:

The only problem that your battery lasts only for 6 hours is due to too much charging...So when you will buy a new battery then make sure that only charge your battery when it will remain only 10%...And try to charge your battery with phone switched off..
Charge little and often, try to avoid deep discharge/charge cycles.
Back in the days of NiCd batteries there was the posibility of memory effect where if you didn't do a discharge/charge the battery wouldn't hold as much charge.
NiMH batteries do not suffer this, but discharge/charge cycles were required because when they started being used very few people had smart chargers so had to discharge to be able to time when to stop without overcharging, and also due to confused information pulled over from NiCds.
Top up charges are better for them too.
Lithium batteries also don't have memory effect, and are better off with top up charges.
Ask yourself this:
What would stress the battery more; running 1A through it for 10 minutes or 1 hour?
Also, as the battery discharges, its voltage drops so the current drain has to increase to compensate, discharging the battery even quicker (remember how capacity graphs drop off quickly?)
Say your phone needs 2W to run, with a 4v battery that's a drain of 500mA (P=VI)
When the battery has dropped to 3.5v then to produce 2W it takes approx 571mA.
batt problem
how to keep my batt good?
I've always just charged my phones overnight while I sleep. Never seen ill effects. If I don't make it home that night my phone still lasts through the next day.
It's not like that battery is irreplaceable. Go get a new one if your battery is nearing the end of it's life. By then you would have probably moved on to a new phone.

skimmed a few parts, but thanks for the read mate, learned tons.
as others allready mentioned, there are many different suggestions how to take care of the battery. I usualy reload the baterry only if the capacity is <= 5%, without unpluging it before it reaches 100%.
thanks for the info!
Hey i flashed my device with the battery at around 80%.
after the flash it was 100%...
so this means i just lost 20% of my capacity? how do i fix this?

I don't believe you have lost capacity. It's only your gauge that's slightly altered. If you recharge your device fully(and about an extra 30min) you should have the regular capacity
How could going from 80% to 100% equate to a lost ???
it's posible that you'd gained the extra charges while the flashing process was going on ( because it was plugged in ?? ) ... if it wasn't ... no idea why

If i understand the post correctly they are equating am 80% to 100% a loss for 2 reasons:
1. because he would have lost charge while flashing due to the massive battery drain.
2. because now he is stating that his 100% is really only 80%
but i would probably just leave it charge overnight and you should be fine, the gauge just sounds to be off, it shouldnt be a true loss (unless the battery is bad)
Is there any other way to sync the battery with the device? I been trying a full discharge then charge.
I am using a mugen extended 3000mah battery and at 15% 10% and 1% it will stay there for some time before it starts to go down or turn off completely if it is reaches less than 1%.
I don't think you've lost capacity.
I believe you just did a quick check before flashing (and it was already charging before you started right?), and the battery gauge wasn't updated. I had this a couple of times while recharging. I take a quick look and think "this is gonna take another half hour". Five minutes latter I check and the charge led is green again.
Sometimes the battery metter lags a bit, you have to check it again to be sure when charging.
At least it happens to me.

Alrighty. I have done three so far. It has gotten better then the first time I got it. But its not perfect.
is it safe to discharge it to 0% so that it will shutdown? or what?
Hi guys,
I've noticed that if I plug my phone to the wall charger, when it reaches 95% it just stops charging. I can unplug it and plug it again, and I can reach 100% by repeating the process multiple times, but not in one sitting?
Is this normal? Does it happen to you? Does it get better?

as far as i know, its an known bug
Its by design - charging the battery to only 95% level & then the following discharge. It elongates the battery life. It should never charge to level's exceeding the above.
It's not a bug.
Most batteries lifespan drop if being on high voltage too long (100%)
So usually manufacturers will try to let it state it is fully charged before it even reach 100% to extend the lifespan of the battery.
But if you really want to see it charged fully you can do a battery stats wipe in recovery after a ROM flash. It will be able to charge to 100% fully.
Hope that helps.

tried this methode, but no success.
i come from a X10 and SE build in a charging algorithm: battery charged fully, hold this value for one hour and let the battery fall till it reaches 90% and charge again.
do you mean such methode to extend battery life??
the phone from my boss (i9020) charges to 100%, my (i9023) only to 96%
96% is ok, as i said, being in high voltage often kills the battery. 96% keeps it's lifespan much longer.
Being said that, even extremely low voltage kills the battery too. So usually your phone will die before the battery reach 0%
Not this again
From the FAQ post, in this very forum, which should be read before posting a new thread:
Q: I unplugged my phone, and my battery dropped from 100% to 95% immediately, or it won't/takes along time to charge past 99%, what gives?
The answer leads to this informative article about what your battery gauge is telling you, and why 100% is probably not what you want ...

While I thank you for your reply and linking to that article, that is a related issue but not exactly the same. The usual behaviour is for the battery to indicate a 100% charge and then drop to a lower level, as you bolded in your post. The behaviour I'm talking about is it never going over 95%.
Not a big difference, but enough to notice the change and ask about it. Don't you think?
I myself own a GT-I9020T & have never seen the charge levels exceed beyond 95%.
You are right, your description is subtly different than the post in the FAQ. I have to admit laziness in assuming that they would be one and the same 'problem' ... apologies if they're not.
Well, you did give useful info even though you thought it was an old, tired question. I can't see a reason to give apologies there
Turn the tethering on while charging; it'll charge the battery up to 100%
I think my Vibrant had the same issue / feature. It's probably a Samsung feature and not a bug.
Sent from my Nexus S using XDA Premium App
Mine hits 100pct sometimes but will always stop charging until it drops below 90. A good feature to save the battery. Makes 0 sense for it to be charging every time it drops 1pct for hours at night while on the charger.
I'm wondering if people seeing a difference in the overall charge cap is a matter of rom? I've been using cm for practically ever but I know some people are on stock. I'm sure it's possible something is modded in there to make sure it hits 100 before it stops.
Just a thought.

But the problem is that it won't charge beyond 99%. It used to charge up to 100% before if I leave the screen on.
But don't I need to get battery % to 100% (that's what calibration app says)..?
How can I get it back to 100% charge?

Not sure if it works ffor ns, but drain your battery, go to data/system and delete batterystat or something along those lines and reboot. Let it charge for awhile and it should go to 100% . If it works you don't need to calibrate anymore as that's how normal apps calibrate.

drain your battery, delete the batterystats.bin, reboot, then charge all the way. chances are is that you had to wait a bit longer for it to hit 100%. when i charge my phone to 100, sometimes it takes an hour to go from 99 to 100%. be patient, if that 1% is worth it. the more you play with your phone between 99 and 100%, the longer it will take.

So drain it first, delete batterystats.bin, and it should charge to 100%? Because the app I downloaded says, charge it to 100% then delete batterystats.bin.. etc.

you must had something running in the background. believe me, the different between 99 and 100 is almost non-existant
The last 10-20% trickles in. 5hours is way too long though. What does your voltz read bc you can have a full charge as far as voltz go but may be getting a faulty % reading on the charge.
If you use the apk make sure you don't power off or you will regenerate the battstat through normal process and then the app is pointless. Try charging overnight and see if you can get to 100%.
Fyi/beware draining your battery to 0 is not good. Some batteries and phones have a hard time getting through first boot when there is little to no charge in the battery. Whenever I use the calibration apk, I never go below 10%. Anything below that can cause some funk.
I drained it all the way and deleted batterystats.bin, charged it all the way back overnight, but it doesn't go over 99% for many hours. I stopped all the services I could possible (kept only the essentials)...

Yes your phone sometimes gets out of sync with its self and starts thinking that its fully charged or fully discharged when its not. The way I typically calibrate my battery is to turn it off and let it charge until it stops (this is easy to see since the screen lights up and the battery shown on the screen stops unfilling and refilling). I then unplug it and boot it up. Again, shut it down and plug it in and let it charge until it thinks its full. Again, turn it on this time letting it charge to what it thinks is full while on. Finally restart into CWM and use its too for wiping battery stats. After all that I also like to let it die before I plug it in again.

Hello, I would like to know if there are some "rules" considering charging my phone ? For example, do I need to wait until my phone shuts down or doesn't it matter when I charge it.
main thing is dont play games when charging, everything else is fine. it charges faster with phone off than on
1- don't use it while charging.
2- don't let the battery completely drain (charge when it reaches 15%)
3- try to avoid charging overnight
Avoid using it while charging if you can. Don't drain the battery completely before charging, try to leave at least 10-15% battery before you charge it. Don't charge it overnight as the Honor 8 has fast charging capabilities. If need charged it in the morning, before you get ready for the day.
I don't agree that it is harmful to charge a phone overnight. Once a smartphone is fully charged it has a built in mechanism that stops the charging thus preventing the phone from overcharging.

That's true. However, there shouldn't be any danger of damaging the phone if you do charge it overnight. Either way you decide to charge it should be OK.
Oh okay, one more question; do I always have to charge it to 100% or is it okay to remove the charger at (for example) 58%?
Look if your going to charge the phone do it to 100% But if you need to go out before it's fully charged its not going to do anything to the phone.. Just walk with your charger and charge it when your able to..

For modern batteries, it does no harm to unplug your device before 100%.
Actually it is "healthiest" for batteries to be kept between 80%-20%

While that is true. But there is always a chance that the Lithium Ion battery could become unstable after its been used for a while.
