Default Charging Practices?

What has everyone found to be the best charging practices (as far as maximizing use and battery life, while minimizing charge time)?

I'm asking because a friend said that charging overnight was detrimental because it leaves the phone on the charger with a full charge. I've also read that deep discharging was not recommended. Is there a "sweet spot"?

Thanks for any and all help.

I don't condition my battery and I leave it on the charger all night if it needs to charge. No problems so far and my battery lasts 18-20 hours no problem.

Use all day and charge at night. Getting 15 hours with moderate usage and still having 40+% left.

I'll use my phone normally throughout the day. I'm left with around 50% by nighttime and then charge it overnight. About once every couple weeks, I'll drain the battery completely and then fully recharge it overnight. I've done this with all my phones and the battery has never been an issue for me ever.

I just charge mine as needed. I also heard that letting them completely discharge is bad for the life of the battery.

Essentially, charging to full and then discharging completely, then recharging to full again can set the battery stats. No worries about discharging completely

LI ion batterys don't like to be run completely flat, i'm a builder and a few of the tools i use have them and i found running them completely flat before recharging shortens their life, i have friends that have experienced it too.

I do the same, except, in the Radio Control world that uses similar battery technology, you don't want a lithium battery to run all the way down. I charge fully, then discharge down to about 15%, recharge, and the battery is conditioned. Lithiums can be left on the charger overnight. Ni-Cads cannot.

Don't worry about it--the device software and hardware manage charging. It won't overcharge the battery, nor will it let you discharge the battery to the point of damage. Don't worry about the battery "learning" either. Just plug it in and forget about it, and unplug it when you're ready to go somewhere.

I charge my battery whenever I want. I've done it that way with every phone I've owned.
I never listened to any of that "don't charge over night", let it run down to zero then fully charge" crap.

Sounds good. Is there any way to clear battery stats (for a rooted device)?

I have the phone charging whenever possible to preserve the endurance of the battery in the long run. I'm having a charging issue that a few others have mentioned. Some days the phone charges rapidly. On other days it is dead slow or, if I'm using the phone while it's charging the charging indicator is on but but percent of charge might increase very slowly or not at all.

I have several different chargers ,including the oem origianal. The slow charging situation comes and goes regardless of what charger I'm using.

I have a play store app called batery drain. It displays a percent rate of discharge or recharge, depending on whether the phone is running on ac or battery. At the moment it reports the battery is recharging at 2% per hour, very slow. At other times it may report 17% per hour. These percentages seem to correspond to my impressions of charging rates.

If slow recharging is going to be a persistant problem I'll need to have a spare fully charged battery on hand and a stand alone charger for it.

In the week at work I usually charge every night even though sometimes there is 70% or more battery, always think that you never know when you will need the battery In case of emergency.
At weekends I can go one one charge sometimes, really good battery life in this phone.

I have 3 batteries, I usually keep one battery on the app spare battery charger, and one fully charged battery on my pocket. The only time I come my phone to a charger is when I'm driving. I keep the spare battery charging until I need to replace it with a spent one.

I have only one battery for now so I charge whenever I please. But usually charging it overnite and whenever I am driving ...

Sort of a habit and doing it on all my mobile devices (Laptop, Tablets, phones , etc ..) to drain them at least once a month and I don't have issues on them so far .

Ever since I got my Note 2's, I've rarely plugged them in. I purchased 2 of the extra battery stands (w/ extra battery), so I basically swap batteries whenever the battery gets down to below 15%. I have a stand at work and a stand at home, so it's been a perfect scenario for my needs.

I've got 2 on the way (delivering tomorrow) for the same reason - one at home and one at work. With the 50% off coupon, it was a no brainer.

Use all day, charge all night. If I somehow do manage to get the battery low during the day then Ill charge it for an hour or so, the 2amp charges so damn fast that even a short period plugged in makes a huge difference.

Yup. It's been amazing. Only thing that gets difficult is when I have to swap both the International and the Sprint Note 2. In those instances, I'll just charge my Sprint version on my Smart Dock (while at home).

I have a ebay battery as well (supposedly OEM), which seemed to work just as good as OEM, but didn't want to mix it up with all of the others, in the event I ever needed to replace one of them.

One thing to remember is if the phone shuts off because of a dead battery do not try to turn it back on until its on a charger or another battery is installed. Li-po batteries can develop a memory if there voltage is taken down to far.

Personally I don't do any battery conditioning and just connect it to the charger each night before I go to sleep and disconnect it next morning. If I am going to be out on the road a lot during a day I pop it on my car charger while I am out as I use CoPilot LIVE a lot.

Charge overnight, run all day. By the end of the day I am usually at about 30/40%.

I'm into RCs too so I know what you mean but I would think the phone has some sort of LVC control built in such that an indicated 0% would be an actual 20%

I've noticed that the Phone charges up much faster when it is on...as opposed to being off.

Questions

1. when charging your phone....is it best to turn it off (like at night when you are not using it)....or is it best to leave it on?"

2. Is there really a slow charge (like when you turn it off at night and charge it)? And if so...is that better?

thanks.

I don't understand why you guys worry about charging batteries. Li-ion are memory free and chargers have micro processors to manage them.

Just plug in and use. I leave mine on when charging and have never conditioned it or any of that nonsense. Works as it did when I got it.

Two things determine how fast your phone charges. The most important is the charger you are using. If you're using the STOCK 2A charger that's the fastest, whereas your old charger from another phone is probably only .7 A and takes > twice as long. Note that the chargers for some pads are 2A and will be as fast as the stock one.
There are also some cables that limit what you can charge at, use the stock cable (or equivalent) if it seems to be charging too slow.

As far as it being on - whatever power that is being used by the phone will not be used to charge the battery. So if the phone is sleeping it really doesn't matter. But if you are using the GPS with a navigation app giving turn-by-turn while listening to music in the car you might only be barely keeping up with the drain.

Something to remember - look at the notification page, it should tell you 'Charging AC (or USB)' and if you are on AC and it says USB then either your cable or charger is too weak or the wrong one. That's the slow charge.

I know it's always more convenient to have someone tell you in one sentence what to do to care for your battery, but I find the internet to be a vast source of content if you search for it.

It re-iterates a lot of the advice given and also puts some of it into context.
