recharging transformer every night

So I finish the day with 22% battery life left and I'm wondering if I should put it to recharge already or fully drain it out to about the single digits. I don't see the point in leaving it around 22% so I can run out of battery during the middle of the next day. Is it okay to do this every night while I am asleep or will it cause some harm to the battery?

I think it's OK. The battery is lithium ion not NiCd. I read somewhere that it may be even better to recharge when it's half way than when it's completely drained.

This is true. Taking a lithium ion polymer (LiPo) battery to extremes, it degrades the battery life. Also try not to keep it plugged in for more than an hour or 2 after it reaches 100%

I charge my TF every night be it at 70% or 30% same as I do with my cell phone.

(1) This is lithium polymer battery. It doesn't like being at low charge for an extended period of time. In fact, it likes being charged regularly.
(2) There is nothing wrong with plugging it in at night and leaving it plugged in til the morning. There is a regulator that will stop charging when it reaches 100%.
(3) Do not treat this like a nickel ion battery. Again, you will not have memory effect from this by recharging it often. In fact, that's what this battery likes.
(4) Lastly and most importantly, this is YOUR device. YOU use it how YOU see fit. Even if it's not good for the device to be plugged in over night, what are you going to do? Set your alarm clock to go off at 3 am so you can unplug it? YOU are in charge. Do what's convenient for YOU.

I always leave my electronics plugged in. Its like a laptop almost. I have my laptop plugged in all the time unless I need to move or something, then it switches to the battery, but while its plugged in its running on the AC power source. I assume this what happens with these type of devices too iPods phones tablets etc etc etc,

How do you recharge your tab

Do you turn it off then plug to the wall?
Or do you recharge and let it in sleep mode (Can this somehow shorten the battery life?)
Also is it necessary to use it till it goes under 15%? I'm in the old school era for battery charging, I always let it drain till 0% and then charge it.

I turn it off then plug to the wall..
and I let it touch the 5% mark and then start charging it

Draining the Lithium-ion empty is very bad idea and will reduce the battery's maximum capacity over time.
Li-ion battery works best when they are in a charged state, unlike older Ni-MH and Ni-CD, they don't have "memory" so you don't need to draining it to 0% periodically to reconditioning them.
I normally let the battery drop to 20% before charging.
I really don't think it's harmful to charge the Tab while using it, but the battery does charge much faster with the screen off.
That is the one thing I miss about the Xoom. It can charge about 1% every minute even with the screen on full brightness.

I turn it off before using the wall charger. I don't wait until any specific battery percentage, I just charge it if I think I'm going to be on it for a while.

I charge it every night in sleep mode. My theory is that the less you have to charge it, the less heat the battery will generate. Heat is a battery life killer.

Then I unplug it every morning and leave it in sleep mode until I get home. Usually only drops 1% over 10 hours in sleep mode.

I have a suspicion that the majority of batteries will last about 2.5 years before they start to degrade, regardless of how you charge them.

On Charge More Than 15 Hours a Day Hurting Battery?

I charge my phone overnight, from around 10PM to 8AM, then I leave my phone charging in its dock from about 9AM to 5PM during the work day...
any harm in doing this? I'd like my phone to last quite a while, as we are currently in a serious relationship, and I don't plan on letting her go....

What hurts your phone battery is not charging it but keeping it on high temperatures for a long time. And guess what keeps it on high temperatures: yep, you guessed it, charging for a long time.

While it always depends on the charging circuit, keeping your battery topped up by constant charging (even trickle maintenance) will reduce the voltage level that it can be charged to. This will take quite some time to notice, and several deeper charging cycles will "repair" this to a certain extent. But with any battery, keeping it any constant level will reduce its charging capacity, and continual charging (trickle or otherwise) will "cook" the batteries chemical make up sooner.
To do what you're doing everyday will absolutely have an impact on your battery's health over the long term. But to exactly what extent is based on several factors I don't have specific data on.

Absolutely, our phone battery is designed for mobile usage, not to be tethered to a charger constantly. Constant charging is unnecessary, wasteful and leads to early battery demise.

And aren't our high end modern phones also designed to trickle charge when it gets to %100, so no harm can come to it?

I suppose it depends on how you define "harm". Read my post above again. Any level of current that is continually supplied to a charged battery will accelerate the aging of it.
Even if the charger were to shut off completely, and then resume charging at a certain level (which I believe is the behavior of the LG wireless charger at 95%), continually discharging and recharging from 95% to 100% is probably not ideal.
But all of this is probably not all that great of an affect in the grand scheme of things. You're not gonna kill your battery in a matter of months by leaving on the charger all of the time. Yes you will accelerate the degradation of the battery's health over time, but if your phone is in use enough so the battery is being discharged regularly between charges, I doubt that you will notice it for a long time, if at all.
I can say that if you simply leave it charging 24/7 without any other kind of use you will be able to measure degradation surprisingly soon. As to how noticeable it will be is very hard to say.

I use and suggest Battery Monitor Widget from 3c. It takes the guess work out of what you see when you're charging and what happens to the phone when it reaches 100%.
As the phone gradually reaches 90%, charging is noticeably slowed. From about 92-100% it trickle charges from around 300 to 200 to 100mA until it reaches 100%. Charger stops charging when full and lets the battery level drop slightly before charging it back to 100%. You're constantly topping it off at full and batteries of this chemistry don't like that.
As far as I can recall, these types of batteries actually thrive on being run down and cycled back up. The only catch is, don't run them down until it's completely dead. You've significantly cut the life of your battery if you do it quite often.
To answer your question, it probably doesn't hurt that much. If you do it for months, maybe years. Yeah, you'll see some degradation.

I would correct this and say the battery loves being near the median. Store at 40% battery! 100%-0% is bad... 100%-10% is better, 90/10 is better etc...
80/40 is really good for preserving charge cycles. Basically, charging at 30% back up to 70% is better than letting it go down to 0%
Note: this is a REALLY good battery in this phone. Just USE it until you feel it's dying too soon and buy a new one. Batteries are cheap and will be cheaper in 2-3 years.

But we can't buy battery for this phone.. I always let it run down to 14% that's when the warning message pops up.. Then back up, charges in 2 1/2 hrs then I leave it on an hour more until I leave from work so I could have a full phone.. Note, I work over nights, so its dead at around 2 or 3 am sometimes, then I leave at 6 am..

Most of us in here don't keep our phones long enough to notice any battery degradation..
Just charge it as often as you can but unplug it when it's full.

To be safe I would let the phone idle off of the work charger and only plug in at home.

Agreed, I only charge once a day and it's usually sufficient, if your a heavy user and are concerned about the phone dying at night, let the phone decharge normally throughout the day and plug it in an hour or an hour and a half before you leave, however long it takes to charge the device after a workday's worth of usage (Whatever that is for you)
I do this myself if I'm using my phone heavily during the day and know I'll be out all night. Like some said you'll probably never even notice the degradation, but when you know it's not good for the battery in the strictest sense why risk it, the phones aren't designed to be charging 2/3rd of the time, they are designed to be charged and then taken off the charger and used.

Getting my new Nexus 6P from Google Store today and have a few questions

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

How and when do you charge your battery?

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?

Battery łasts a long time as it usually goes off the charger at 7 a.m. I charge it while sleeping. Occasionally out of habit I will charge it while I'm driving in the car but for about 15 minutes. Otherwise, I am very happy with the battery.

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.

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%.

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 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 ?
Sent from my SM-G935F using Tapatalk

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.
