Using battery for the first time - Galaxy Note II Q&A, Help & Troubleshooting

Is it better to gully recharge it before I turn on my phone for the first time or should I drain it down to about 1 % and then recharge it? Or does it not matter? Thanks!

How come? Does it calibrate itself?
The manual says to charge it fully before first time use or long time of no use?

Yes it calibrates itself. these new lithium-ion battery are "smart" battery and they have this little trigger that tells them when the battery is fully charge so they dont get over charged or anything. All you need to do is put the battery and start using the phone.

Im sure li-ion batteries are not to be fully drained. To have long battery life, i think you are to charge as often as possible and never let it fully drain - although the phone seems to check voltage and forcefully shuts down when the battery is really low.

Yeah it really doesn't matter.. And it's really never good to let your battery drop to 1%..I try to never let my lithium ion battery go below 10 if I'm near a charger

Yes a fully drained battery isnt as good as charging like around 5% or so but theres no calibration needed, just put the battery and do your thing.

(Q) External battery charging issue

Does anyone else have this issue?
I recently bought the extra battery and charger (that comes with the second batttery) and here within the last few days, I have been charging the unused battery overnight and then it turns greens sometime during the night and then in the morning when I go to put it into my phone, it boots up but states battery life at always less that 60 instead of the full 100%.
So if anyone knows as to why this may be happening, I would greatly appreciate any feedback on this issue that has me pissed.
Thanks in advance and also if somthing like this has been posted then I apologize. I searched and did not see anything along this matter.

So ur not charging battery from ur phone? Try doing that and see if it does the same thing. Is u phone rooted? If it is, than there is a possible resolition.

The external charger may be shutting off too soon. Do what Lord said.
Also please put a subject in when you start a thread like "External charged battery only shows 60%"

Its the same charger I plug into the the spare battery case thing to charge and the light stays red for a long time then it turns green as if its done charging but when inserted battery into phone and power up, its usually around 60% charged or less. But I pull charger out of the spare battery holder and plug directly into my phone and it charges to full ballery.

The battery holder like the phone has a sensor that tells it when to stop. It is working incorrectly....broken.

How do I wipe battery stats?

It seems like it takes forever to charge my phone now how can I wipe battery stats?
Sent from my SGH-T989 using XDA
Has nothing to do with battery stats.
It gets auto wiped when you charge your phone to a certain level to almost full.
If it takes too long to charge, get a 1000mah charger and don't use a 500mah one.
Hope it charging from the wall and not a PC

Data/system/ batterystats.bin just delete it.. Or boot into recovery and clear battery stats...you can check your cable or change the outlet at which you charge your phone, you might also want to check your battery for leaks which could potentially damage your phone..

Battery Stats

I know it's necessity is argued but I'd like to ask if anyone has noticed a difference when wiping battery stats on this phone.

No. and please search. There was a big thing about this a couple months ago from a Google engineer.

I am aware about the statement from the Google engineer but I have read other anecdotes about it making the battery percentage reporting more accurate. I was curious what peoples' experiences are with this phone.

The battery stats have nothing to do with actual battery life but can make a difference in the reporting of the charge level to the operating system. The only time i've noticed anything more than a negligible difference was when switching from the standard battery to a 4400mah extended battery. Before wiping the battery stats and letting the OS 'learn' how much charge the battery was capable of the battery gauge would fall down to 3-5% normally and stay there for hours on end, with the screen on and playing FF3 at the time.

Thanks. I'll probably do it when I have some free time since my battery life seems a tad bit short from what it should be. I usually get it plugged in before it goes under 20% so I don't know how it behaves at single digit percentages.

Proper battery maintenance

Hello, I am curious what the proper maintenance for the battery is? I have 2 spare batteries and an external charger. Should I leave one on the hook all the time or let it charge the battery take it off the charger when it is full? Thanks!

Let it charge until full because it will get damaged if over charged.

Ok so it is Ok to let a fully charged battery slowly discharge while it is not in use?

How long should a battery hold its charge while not in the phone? I charged one fully and after 2 days I put it in my phone and I had 8 percent left :/

1) Lithium Ion batteries can't be overcharged.
2) If your batteries are going from fully charged to dead after 2 days without even being used, either the battery is garbage, or the phone isn't reading it properly. What level was the original battery at, when you replaced it with the one you had previously charged? If you plug it into the charger while it's in the phone, what happens?
There's something wrong with that battery if that's true.
I charged my spares a week to two ago and they're still at over 90%.
Leaving it on the charger is not something I'd recommend. It can be "overcharged" if there's a malfunction in the charger (it's not that this type of battery can't physically be overcharged, just that there are precautions in place to prevent it from happening) - and why tempt fate ? The protection circuits in the charger are a form of protection, but you shouldn't rely on them - even ones from the "good" manufacturers can and have failed. Failure can lead to overheating which can lead to a fire.

Bigger battery leading to bigger problems.

So i got the 10,000 mAh Zero Lemon attery and i LOVE it... i am currently at 4% battery and my phone has been off the charger for 5 days and 1 hour. its amazing.
but now i ran into a moderate issues.
when the phone stock battery hit 5% it was roughly at 160mAh and stops allowing the phone to do certain things like update my dropbox use the camera.. ect.
now when the phone is at 5% it is actually at 500mAh which is almost 16% on the stock battery and i should be able to use the camera.
technically if the battery low warning is to help protect the pgone in some way then i should be able to use my camera up untill the remaning battery on teh 10,000 mah battery reaches 1.6% battery.
i would like to just disable all battery limitations completely if that is possible.
any help would be awesome
Im rooted and use Wanam/Xposed and set critical battery to 1%

It's gonna look like a h2 hummer anyways because of the case it comes with is an otterbox knockoff. It does a great job at protecting the phone though:thumbup:
