The battery in a nexus 7 flo is a Lithium ion battery (as one would expect). This particular kind of battery lasts longer if you top it off all the time (Meaning you should charge it whenever you can). A table and explanation can be read here: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
What the first reply said. I charge when it's time to do so.

I did some reading on battery university some time ago and concluded the best way to save battery health is to keep it as much as possible between 40 and 80%, as well as try to not leave it full or completely discharge.
I've been using this method on my phone for more than a year and the battery hasn't noticeably lost capacity.

I charge it whenever possible, Battery nowadays trickle charge so always plugged in does not damage battery longevity. Install Gsam battery monitor and you will see even during charging the battery doesn't get much hotter than 30C and Lithium batteries is fine at temps below 45C.

+1 for me. When I pick it up to use it, I like it a 100% charge. I don't always know when I first disconnect it, if I am going to use it for 5 minutes or 5 hours. If I waited until it called for a charge and picked it up with, say, 25% power, I would be screwed if I wanted to use it for a long period of time. I wish they came with swappable batteries like a phone, so I could get a couple of spares, keep them optimally charged and then switch when the one in the N7 got low. Alas.
I charge mine while I sleep. Haven't ran it dead yet.

Best solution is a portable power pack, it just adds some extra bulk. Someone will eventually release a battery pack case to take advantage of the wireless charging.
Is it still the case that the earlier you recharge, the longer your battery will survive? I haven't run my Nexus 7 into the red so far, which is pretty easy to avoid when it lasts for longer on one charge than I could ever imagine using it non-stop.
There was an article on Gizmodo that recommends not to let it go below about 40%. I would post a link, but XDA's not letting me.

This. You guys that are allowing it to reach the point where it tells you to change are causing premature wear on your batteries, especially if you allow it to reach the point of turning itself off. Nothing is going to immediately fail, you're just going to start wearing out your battery faster. We'll all eventually reach that point of reduced capacity or inability to accept a charge.

I try charge my devices before they hit 50%. Doing so will about double the longevity of you batteries. Of course their are times when this is not possible, but with a car charger and several QI wireless chargers it not a problem most of the time.

Do you only let it charge to 80%, or do you let it charge to 100%?

Only up until 80%. If you have to charge close to 100%, at least try not to leave it in that state for long, since that's what damages the battery. Also, try not to discharge below 10%.
Of course, these are all just guidelines. You battery will degrade anyway, it's just a matter of time. There will be minimal impact if you do a full charge-discharge cycle from time to time, but the less often you do it, the better for your battery :good:

I remember as a kid, when getting new hardware, you need to charge it to the maximum and leave it in for a few hours to kinda work the battery and get the most optimal battery life. So for this phone, what would you need to do when you first get it to get the battery to be the best it can be?
Do we cycle it from 0 to 100, or just charge it to 100 and leave it?
Or does it not matter?

It doesn't matter. While older nickel-cadmium batteries could have issues with charge memory, lithium ion batteries are not affected. Just charge and use your phone as normal. If you want to maximize battery life make sure not to place your phone in extreme heat (eg. inside a locked car in summer time) and avoid leaving your phone at 0% charge for any length of time.

Nope.
These new Lithium batteries aren't subject to any of these myths.
Same with the "Take off your device from the charger once it has been fully 100% charged or the battery will stuff up." Nope. The battery just cuts the charge and just runs down. That's why if you look at your charging history, it might go to 99%, 98 or even 97, and go back up to 100% because that's when the phone decides, "Yep, I'll take a bit more charge."
Alright. Thanks to everyone!

Lithium-ion/lithium-polymer batteries don't have the "memory effect" that older nickel-cadmium and nickel-metalhydride batteries did. So there's no point trying to run your battery down low every now and again to help its life. In fact, it seems that charging it more often is the most helpful thing, i.e. lots of small charges rather than big charges all the time.
Just use it normally and charge it when you need, it'll be fine.

How about leaving the phone charging after it is fully charged? Like when you charge it overnight.

The phone and charger electronics will lower the rate of charging as it reaches 100% and turn it off when it's done. You don't need to worry about unplugging it right away.
In longer term storage situations where you aren't using the device (i.e. weeks or months) it's optimal to store the battery at a charge level of 60-70% to reduce battery degradation over time. When the Mars rover \Curiosity was en route to mars the batteries were at 60% and were charged upon approaching the planet.

I am an electrical engineer actually. Li-Ion or Li-Po batteries do not need to be treated any special way. The only thing that degrades them is use and time. And it does not matter how deeply you discharge them (discharging to 50% twice is about the same wear on the battery as discharging to 0% once, within a reasonable degree of error).
What you may have been reading was with regards to calibrating your laptop's battery meter. There is some truth to that, and allowing even your phone to discharge completely (down to 5% or so) once can help make sure your battery percentage is accurate. But it does not affect your battery life at all.

Actually, it doesn't say to do it "first". It says "its a good idea to fully charge *as soon as you get a chance*."
The wording in the quick start guide you provided doesn't seem to imply that its a critical thing. It seems to me that they are putting that there in case someone takes it out the box, starts playing with/using it, then wonders why the phone is already dead. Then they post to XDA about how the battery life sucks. (Just kidding! )
I generally try not to charge my note 2 overnight. I want this battery to be healthy as long as possible, so I don't want it to sit at high voltages for too long.
Normally my note 2 is around 80 percent when I go to sleep so I don't plug it in at night, I just plug it in in the morning for an hour before going to work. It reaches 100 and then I remove it.
The times when my battery is much lower that I won't be able to charge it in the morning in the hour, I do charge it overnight.
What I've noticed is that the battery drains much slower on the days it's been on the charger overnight.
So I'm thinking that the charger will continue to raise the voltage even after it reaches 100%. Maybe someone has some other thoughts, but I just wanted to share what I've noticed so people are careful with their battery.
Hi,
Charge it yhe way you want. Don't stress on it.
But for a few tips:
Don't let the lithium-ion battery go down to critical battery levels before charge.
Don't put the battery on the refrigerator.
Don't over charge it even if it's a new battery .

You can but can potentially damage the battery. It's up to you.
I'm going to disagree with you guys. The charger and the battery has overcharging protection built in. So don't speculate with overcharging overnight. In fact when the phone has stayed longer on the charger I got better battery life. Cheers

Yes, I know. So why would you charge your phone overnight? So it would stay 100% when you wake up?
I charge my phone overnight everyday.
The battery magnet would trigger the charger into trickle mode. This prevents overcharging.
Li-ion battery prefers to be charged then discharged. Contrary to hearsays, discharging it to critical levels too often would actually degrade battery life.
My Nexus one of 2 years still maintained a 84% charge because of this.

The battery have both overcharging and undercharging protection.
So there is no problem charging your phone overnight, the battery will stop charging when it is full. It will then be allowed to discharge a bit and the charging cycle will resume. The fluctuations caused by this charge/discharge cycle are usually hidden by the firmware so that you only see 100% - charged.
As for undercharging, it can indeed kill batteries, but it won't happen unless you drain the battery completely *and* let it self-discharge for a few weeks.
You don't have to adopt a specific charging pattern to keep your battery in good shape, just do what's most convenient for you.
Some tips however :
- Avoid high temperatures, batteries don't like it. The fridge is actually a good place to store your batteries provided that you took the necessary steps to prevent condensation.
- Store unused Li-Ion batteries at about 50% charge. Fully charged batteries have a lower shelf life, the 50% are there to prevent self-discharge from causing undercharging.
- A full discharge-charge cycle won't make your battery healthier but it is useful to recalibrate the power gauge.

I see. Well, in your case it may be better.
Because during the night it gets more time to detect the proper voltage and stop.
And the battery is removable for a reason. It'll have over 80% original capacity even after 2000 discharges and it's only $20 at most to replace. No need to stress it over. Use it all you want and replace it the time comes. Leave the stressing over to the non-replaceable guys.

You telling me if i charge once a day, the battery will still have over 80% charge after 6 years of years? I find that hard to believe as all my previous batteries have to be replaced after 2 to 3 years of use.
That's the quote from manufacturers under ideal conditions. The only devices that I haven't threw out for that long are laptops and the battery in them are still working flawlessly and holds a reasonable charge.
Even tiny LSD batteries can have up to 1000 charges so higher capacity ones will last longer and be more durable due to the increased amount of cells. Just like how higher capacity nand will last longer than lower ones.

Avoid using extended battery life.. Charge your phone til 100% and used it till gets to/around 10% and then charge it again so that the charging cycle is fixed. If you are rooted make a full wipe and install any ROM you like with some good kernels out there that matches the ROM. :good:
It might also be a rough app that you recently installed. Use BetterbatteryStats or Wakelock detector this will show you what is causing the unwanted deadlocks and causing battery drain. :good:
Hope this helps you.

Hi I'm new to nexus 4 and have a battery question. I didn't want to start a new thread. I bought a slightly used nexus 4 and charge it to 100% after only a minute of use it immediately starts to drop. Is this normal? I ask because I had an HTC sensation that I charged to 100% and could at least get 10 minutes of use before battery started to drop. Is there something wrong with the battery or is this just the way the nexus 4 operates?

Nexus 4 works this way.. Its all right if battery drops in a minute.. There are plenty of process and their corresponding syncs that actually causes the battery to drain.. Try some different kernel all are good you will get more battery backup.:good:
BUT Stock Rom + Stock kernel are THE BEST.
Maintaining battery health requires a bit of a balance. You don't want to frequently do deep discharges, but you also don't want to charge your phone every time it drops by 10%. If you're sitting around with a charger, plug your phone in when it hits 50%, then let it charge fully before unplugging it.
Overall though, batteries just degrade. You're not going to have a huge impact on the health of your battery unless you're charging it every time it hits 95%.
How about using a slower charger over night? I believe the OEM is what, 1.2amps? I have a couple 1amp chargers from previous phones I had. Will that charge slower/safer?

Modern lithium ion batteries are fairly robust and more chemically sound than early rechargeable batteries. However they do have a finite number of charge cycles.
But you have to understand what a charge cycle is, a full drain to 0 and charge to 100.
So for example Draining to 50 then up, then 50 again then up= 1 charge cycle.
So... Draining it to 95 and bumping it to 100 would take 20 times to reach 1 charge cycle.
Trickle charging vs the oem power used isn't going to make much difference either.
Being ocd about the battery is just going to make you pay more attention to it and thus making you more aware of drain...just use the darn phone and enjoy it!

there is no right way. plug it in when you need a charge, or when there is just a plug around and you want to top off. you do not need to discharge battery to a certain point then charge. just charge it whenever. all these other theories are just that, theories. at work all day, i bump charge it whenever i reach around 80-85%. my battery has not gotten worse. and when im not around chargers, my battery is built to last. i average around 5.5-7.5 hours screen on time, depending what im doing, and im a heavy user.

truth.
The battery will only be able to take 1.2 amps or what ever, for the first 10% or so of battery life. By 25% charge, its only sucking around 750ma, and by 50% you are lucky to suck a half amp. Lion batteries do not charge via constant current, they charge via constant voltage (with the voltage dropped for 25% battery charge or less due to over current). So as the battery charges (aka increases in voltage) it draws less and less current.
You want a tip from a guy that has to run the lion battery analyzer for flight modules, keep your battery between 15% and 85%, and long term story them around 30%-40%. A pack that is left on a good charger ($75 or more) charger and never gets below 98% will loose its capacity at double the rate of a pack that floats above 15% and only gets charged to full when needed.
Ive had packs in the field coming back for recal from 2003 still holding above 90% rated capacity because they dont leave them on the charger and dont let them go dead in a locker some where. On the other side ive had 2 year old packs come back that are at 80% capacity ( i fail them at 85%) or less because they sat dead for a year.
Hello!
As the thread title states, I heard that charging the phone when it's powered off to a full charge is more beneficial to the phones battery, before I turn it on for the first time.
Is there any truth to this rumour? Or am I just fine to turn on the phone and charge it from whatever percentage the battery is at out of the box?
Thanks!

As I understand it, all the batteries are charged before being shipped anyway. That is as good as / counts as the first charge. You should be able to use it at will.
Generally I start playing. After the first 3 or 4 full charge cycles it gets to the optimum in my experience, but that may be the phone calibrating itself.

One thing that I do believe makes a difference to battery life is a slow charge. I keep my Note 3 on charge at night using my Note 1 charger, and it is taking about 6 hours to fully charge. I am not certain this is 'better' than a fast charge, but it seems logical that the battery could last longer (more cycles). Does anyone know (not guessing, like me)?

Yes, but that is enough.
This thread will no doubt attract the usual plethora of wild theories. From everything I have read (sometimes from actual engineers), there is little or no truth to any of them. Just use it, charge it before it is empty (typically before it hits 10%, but the higher the better), and use it etc.
The only reason any full charge/discharge cycle may appear to help is that the phone calibrates itself to this battery. That can make it 'last' longer in the stats, but in reality it will not run out any slower.
You only need to cycle the battery if you're having problems with the calibration. (ie. It keeps turning off at 20%)
Cycling the battery to make the charge last longer is a placebo.
Phones are charged to +-30% before shipping. This so the device can be tested before shipment, and by the customer in the shop.
Best is to keep it between 90 and 10%, though in overall run the difference is that your battery lasts about 4 weeks longer before you have to replace it.
The advantage to charging to full: You can play with it longer on your first run.
The disadvantage: You have to wait 90 minutes before you can play with it.
That's it.
The old 'drain and fill' principle does not apply to Lithium-Ion.

Basically what ShadowLea said... High voltages, and low voltages stresses the battery, shortening its lifespan.

Perfect! I knew I had read somewhere (I think from XDA dev shen_ye) that you should keep it between 90 and 10!
Does it really only take 90min for a full charge?! I knew it would charge faster but that's really fast

With the original charger it's a little under 2 hours for 0-100%. So from 30%, about 90 minutes.

Woo! Thanks! That'll give me plenty of time to start transferring over my old stuff to my new SD Card
Hello guys. I've read some articles regarding Li-Ion batteries, how to take care of them. Though our device have a Li-po. (Dont know whats the diff.) I apply my Li-ion charging to our device.
I got the attitude to top it off whenever I got a chance.
I usually charge my phone 30-50% left on my battery.
I really dont try fully charge my battery. I plug it off charge whenever I wanted to. Cause partial charge is always better than to be full charge all the time.
All this was base on Li-ion, how to take care them.
What the others how do you?
Thanks!

I charge it always from 1% (or empty) to 100%
(Maybee two exceptions in 10 months.
It should be calibrated that way all the time according to what i see in threads. But I really dont know is it wise or not.

Got my N4 15 months ago. I put it on charge, take it off the charger whenever I feel like.
No issues with the battery performance what so ever.

Is it just me or the usb port needs to be yanked quite good to pull out the charger? seems like it's too tight. i'm using the original cable + charger

This is not a good idea. You should avoid completely discharging li-ion/po batteries, rather doing partial discharges.

android itself wont allow fully discharge.the 0% android means still have some juice. but because doing a fully discharge on a lithium based battery is not good, google implemented that auto shutdown.even the bootloader haves a check so you cant turn on it if you have really low bat.
I'm not too worried about whether I charge this way or that say but I do know a while back I watched a video explaining about these batteries. The batteries that we have are "smart" in a way by for example when it reaches 100% it doesn't keep charging it'll drop down to 99/98 and then charge back up again
