Battery Care/Battery Life

I want to make the most out of my galaxy tablet 10.1 battery life, i was wondering what would be the best care for it. Each 1% for me lasts about 4 and half minutes on 40% brightness, wifi on, gps off, and auto rotation off. I heard the g.tab gets close to 9 hours of battery life, but I estimate mine about 7.5ish? Also, would it be best to completely drain the battery and then recharge to 100? I heard its not good for lithium battery to drain completely and recharge because it will put more wear to it. Any suggestions?
Thanks

There are many theories but the following is what i follow.
It's not a good idea to discharge below 20%.
Lithium batteries don't like to be stored fully charged for long persiods of time, lithium battery is most happy at nominal voltage, so it's not a good idea to leave your device connected to charger if not needed.
I seem to get 1hour of display on use for 10% of battery, this is with minimum screen brightness.

Having read up about this I have decided to charge mine every night no matter what the charge. A typical day use can leave me with 40 percent to 80 percent left. I discovered that a charge cycle is not the same as a charge. A cycle means 100 percent of the charge stored being taken off and put on the battery. So if you use 20% a day and charge each night that is 1 cycle in 5 days not 5 cycles. There is no reason to avoid plugging it in as you dont want the charge to drop too low or else the battery is lessened very slightly.
I am sure there are lots of opinions on this but am happy with the above and battery performance is great. I was worried about unnecessary charging but that is not the thing to worry about - do anything you can to keep it over 20% (although a near total discharge every month would be good to keep the calibration in check).
Don't stress about it too much. Just enjoy the device. With sensible use your tab will he long replaced and discarded before the battery fails.

^^^ my thoughts exactly. By the time the battery fails to hold a charge, the device will be far out dated...

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,

TF300 Battery / Charging discussion thread

Please discuss everything related to battery or charging in this thread

Great! So I got myself thinking about the dock charging situation: Why is it so that the dock charges the pad instead of the pad drains the dock?
In my opinion it is better (or more logical) that the pad sees the dock as rendundary battery and drains it at need. F.e. the pad runs till 50% then drains the dock completely dry and then uses the rest of its 50%.
Btw: I wonder if the dock charging logic is realized with hardware or software by Asus...

Um, at the end of either scenario, aren't you left with the same overall usage time and 2 dead batteries?
And isn't your preferred scenario almost exactly what happens in real world use?

what widgets drain battery?
i know widgets like weather, email, news drain battery because they need to update, use internet connection, so i don't use them to save battery.
but what about "offline" widgets like google play music, clock,... do they drain battery too? they don't update information using internet, but they do update "offlinely" - i mean, for example: google play music, now it shows the song "A", then you open the app and skip to song "B", when you go back to homescreen the widget will show song "B". so it has to update, does this drain the battery?
lol i guess i worry about battery too much, and just figured out that i created the thread "should i use battery saver app", i should have post it in this thread, sorry

and does leaving the charger plugged in to the wall outlet when not charging the tablet harm the charger or waste electricity?

CHARGING/DISCHARGING TIP:
LET THE DEVICE (THIS GOES FOR ANYTHING WITH A RECHARGABLE BATTERY) FULLY CHARGE.
UNPLUG, THEN LET IT FULLY DISCHARGE...ALL THE WAY!-- JUST LET IT DIE WHERE IT WONT TURN ON.
Doing this will increase battery time, decrease battery wear/tear, possible damage done by overcharging.
Do this on a regular basis, and youll start to see it will last longer then 10hrs
Because of this, i run alot of widgets, on performance mode, i have around an extra 30MIN, so 10hrs 30min is my batterys life.
*leaving the device plugged in,charging when its full, is bad!
*using the device, while charging, burns up the battery, youll notice it getting hot.

Picked this tablet up the other day. I noticed that when I took it in the car and plugged it's charging cable into my car usb charger (kengsington powerbolt) that it did not show that it was charging. Is this common? The charge has worked for all the phones I've plugged into it.

I believe you are mostly right, but letting the battery constantly drain and recharging from 0-10% makes it work really hard and it makes in turn the life of the battery less. But in terms of life we are talking about a couple of mins less every half a year or so, since these devices get replaced by new ones every 1-2 years I guess it is ok.
If you want to sustain the most battery life just charge it from time to time when it gets lower than 40%. If you are having problems with battery duration, charge to 100% let it discharge completely then charge again until 100% without interruption. I do the full discharge and charge every month or so.

i heard many people say letting it fully discharge (use until it turns off) and charge back to 100% will harm the battery, (or battery's lifespan). i read many guides online and all of them say this. i asked other people in other forums and they said the same thing.
but i guess you're right that it will improve battery life, in about a half year or a year (depending on how often you charge), then the battery won't be able to hold a long charge anymore. it won't be a problem it you plan to change/upgrade your device next year anyway.

The best battery tips that I use
Remove unnecessary widgets
Use a clean rom
Set your CPU to ondemand and put it on lowest frequency
Turn of wifi when you are not using your device
If you don't need your device for longer than an hour, turn it off
I use it for about an hour during the mornings up until dinner, then it gets a workout and I have never had my tablet die on me, or a need to rush for a charger.

Battery habits

So what are your battery habits with the 6p? Do you plug it in at night and take it off in the morning? Or do you charge it when it drops dead? Or little charging cycles throughout the day?
I have been charging it when it's low. Not leaving it plugged in all night :angel:

I charge my 6P the following day if I seldom use it. Otherwise I charge it sometime before I go to bed. Usually at that time I'm on PC. Interestingly I haven't charged the 6P while I'm sleeping. Doze works rather well.
I haven't run into a time where the phone died during the day, but I'm not a heavy user by any means.

You're doing the right thing by not keeping it plugged in overnight, keeping a lithium battery at peak voltage like that will degrade the long term life onf the battery. Definitely shoulnd't let it "drop dead" either, that's another no-no for lithium batteries. I ususally give it a good charge in the evening before I go to bed, and then a couple of little top up charges during the day if they're needed. You might find these articles interesting:

I plug my phone in every night and leave it plugged in until the next morning. I've never had any noticeable issues with my phones by doing that.

Whether you notice it or not, it is degrading your long term battery life. This is a scientifically tested fact.

Whenever my battery is low I just plug it in. The type c charger is great with very fast. I never leave it on charge over night.

I just charge it when needed or convenient, never over night.

I always charged my Nexus 4 overnight, but with 2% battery loss overnight for the Nexus 6P due to Doze and the quicker charging speed I decided to take care of my battery this time and just charge it in the evening or in the morning while getting ready for work.

Like most here, charge it when it's 20% at the end of 24 hours more or less. Charge till full, Unplug, go to sleep. Doze is good for me too.

I charge it before going to sleep and let doze do the work. And now I plug it in the car and at work too so minimum cycles are used.

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.

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%.

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.
