Battery overcharge ?

What happens if I leave my battery charging over night and I don't unplug the charger once my phone pops up the message telling me to do so. Will my battery overcharge and fail? Or its out safe to leave it plugged on once charging is done?

Your phone will be fine, there are fail safes in place to prevent over charge (and fire/explosion). Its just a "convenient" notification to let you know the phone is done charging.
On a separate but related issue, I don't suggest leaving it charge more than 10 hours at a time, since the battery keeps topping off the charge, and in my experience this degrades batteries a bit faster.

Your battery will be fine. Just don't do it every night and you will be good.

this.
Constant topping up will shorten the battery life. Not something to be annal about but don't do it too often. It also does not mean you have to fully drain your battery before charging, nor that you have to set an alarm so you take it off charge as soon as it read full.

Wait, so I should not charge my phone en route from work to home? About a 30 minute drive... not enough to fully charge the phone, just enough so it doesn't die before I go to bed.
I thought batteries did not have "memory" and that you could charge them however.... is there a good source to read?

Constant topping up will shorten battery life?
Care to back up that statement with some sources?
Heat kills Lithium based batteries.
A quick rate of charge or discharge creates heat.
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
(From the article)
The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible.
should be balanced with this (from the article as well)
batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem.
My recommendation is to keep the battery as full as possible at all times and do a full calibration cycle once a month. Done.
If you want the battery to last longer stretch the calibration to once every two months... However the phone will be obsolete before noticeable shortening of the battery life from doing 30 day calibrations. PLUS THE BATTERY IS REPLACEABLE ANYWAY. So, honestly, who cares?

If your battery overcharges and fails, your battery is a danger to you and everyone around you anyway; no matter what charging methods you use. A properly working lithium ion battery cannot be overcharged.
I suggest reading up on how float charging works.

This is normally what I do, so it charges 5-7 hours a day, I don't normally kill it during the day, but it does get pretty low

Charging Nexus 7 before using it for 1st time?

Should I charge it for like 10 hours, then play with it? or you think its ok to just start playing out of the box.
I've heard stories..where you should, and where it's not necessary.
Thanks

Hmm, I see.:cyclops:

With every electronic gadget using Lithium-ion batteries nowadays, it doesn't really matter how/when you charge it.
Some would argue to make sure to allow a full discharge from a full charge from a battery calibration point of view, so the battery meter is more accurate. It wouldn't affect the health of the battery itself either way.
Things like memory effect doesn't apply to lithium-ion. How often you charge it and how much you charge it (full or partial charge etc.) doesn't affect it much either. The only 2 things that can potential kill a lithium-ion is high temperature and letting it discharge far too low to the point that it cannot be charged up again. Note that all electronic devices will power off way before it even reaches this threshold.

What makaijin says is correct
I had mine a bit of a charge yesterday but it was no where near full.
Used it till it was flat this morning. It's currently on charge and I'm going to leave it till it's full only because I need to stop messing with it and do other things

I charged mine for 4 hours before use.

Although it is probably not necessary nowadays, I like to fully discharge the device, then charge it overnight (so it gets back up to 100% and tops off), then cycle it that way 2/3 times, so properly "condition" the battery, as I don't 100% trust the conditioning done before shipping.
Just as a side note, most of the battery conditioning lore is coming from way back in the bad ol' nicad days (probably 1990's), when you HAD to 100% discharge/recharge the battery, and make sure it didn't overcharge or undercharge, else it would not be "conditioned" properly, and it had a permanently reduced max charge. Nowadays, expecially with Lion, it is not necessary, and may even be harmful to fully discharge/recharge cycle EVERY time you use it. The first few times it's probably best to do it to fully condition the battery, but beyond that, it really does nothing.

"Conditioning" does not occur with li-on batteries, period. Charging/discharging does absolutely nothing for the life of your battery.

Ifixit shows that the battery inside the Nexus 7 is Lithium Polymer. Does that make a difference in terms of conditioning compared to Li-Ion batteries?

Oh, thanks. I thought that was my being paranoid .
Lithium Polymer batteries are actually worse than Lithium-Ion. Don't take my word for it, but at least with older RC Lipo batteries, fully discharging damages them even more the lithium-ion. I am sure the tablet cuts off way before the danger point, but still something to keep in mind.

Here's the deal- and this has been verified on multiple devices with larger batteries- Your tablet will need to self-calibrate the battery meter/charging to the battery. You can expect things like sketchy battery life and running down very low or completely overnight for the first couple days. Once everything "syncs up", you can take advantage of the full potential of the battery. This happened with my Razr Maxx and it happened on my Nexus 7's first overnight. And, talking to people who have had their Nexus 7's a few days, it's common and expected.
As said, it is NOT the battery conditioning, it is the device calibrating. The battery is pretty big and there's a period of time while the device learns.

I decided to drain the battery all the way and then charge it all the way up. It's charging right now actually, any idea how long it should take to get up to 100%?

Over discharging a Lithium Ion battery can ruin it in a single cycle. Of course any consumer device should shut off before that happens but deep discharges to the shut off point still permanently reduce battery capacity significantly more than shallower discharge cycles.
In simple terms, you'll get significantly more hours of battery use during its lifetime if you only discharge to 50% than 10% or less.
Lithium Ion batteries never need to be "fully discharged" to the device shut off point and as stated above, it isn't "good" for them.
That said, a discharge from fully charged to at or near shutoff let's the device software measure the battery capacity more accurately so you'll get a more accurate battery reading.
Lithium Ion batteries should not be charged at elevated temperatures. If you just watched a two hour movie, let it cool down before charging. A tablet is a nasty place for a battery with the CPU heating it up. Most manufacturers advise not charging at > 85 deg F and 70 deg F is better. A really good charger will measure battery temperature and reduce the max charging rate at elevated temperatures.
Lithium Ion batteries should be stored at 50-70% capacity and not fully charged. That's ~3.7 V per cell. Those of us who use the device a lot on external power would see a lot longer battery life if there was a mode which allowed keeping the battery below 100% while on external power. It seems every manufacturer thinks consumers are too dumb to understand the value of providing it and switching to full charge mode before we run off on battery power.

I would rather always have my battery near max charge when I take it off the charger than have a battery last 7 years instead of 3 or 4 in a device I will realistically only use extensively for 2. Even more so with a phone where they battery can replaced for $20. I'll take a full charge every time over the battery lasting for years longer than I need it to.
I have a first gen iPod Touch I bought when they were released (2007 I think?). I have left it on a charger for MONTHS. Still holds a decent charge.

Is there benefit to using a battery calibration app like this if you're rooted?

You don't have to but I like to. Mine was like 40% charged when I unboxed

Calibration occurs every time the battery is charged to 100%. It isn't a "first few days" type of thing, it is every single time the battery meter reaches 100%.

I had no choice but to completely charge my N7 (purchased from Office Depot 7/14). When I went to turn it on the first time, I was greeted with small text in the upper left side of the screen that said "show low battery logo" on a completely black screen. No logo...no nothing. Completely blank. Plugged it in, the battery charging logo popped up, fully charged it and it's been working great since.
However, I found it a bit odd as I thought most of these types of devices ship with about a 40% battery charge.
Thoughts?

[Q] Nexus 4 battery

Is it possible to ruin my phone's battery due to overcharging? I charge my phone overnight no matter what percentage it is on, I still charge it I know this is bad, but can this ruin the battery? thanks

You should be able to charge as long as you want w no problems as long as you're doing this in a cool or room-temp environment (rather than say leaving it alone in a car charging at high noon w AC off, windows down & no sun shades on the windshield). If you have your phone charging in hi-temp conditions too long\often your battery swells & you get gradual irreparable damage.

If u make a correct use of your battery it won't get damaged. Extreme overclock, overvolt, etc can ruin your battery, but if u charge it every day because ur battery is empty it's ok, and u won't have any problem.

Normally, when your phone reaches 100 % full battery level, it stops charging and starts discharging. At around 95 % level, it starts charging again. This all takes a toll on the battery, especially over a long period.
If your phone's battery is at or above 50%, leave it alone or turn it off for the night.
I have an external battery pack for use during the day time, just for situations like this.

I don't think that's correct. It should switch to a trickle charge, which won't harm the battery, not stop charging completely.

It'll automatically stop charging itself when it's full, it's impossible to overcharge a modern cell phone battery these days. They are a bit more computerized than the old nicad batteries from back in the day. It's actually healthier to give lithium batteries partial charges at a time instead of draining to zero percent and charging to 100 percent.

I doubt it. Could be a faulty battery, but more likely to be apps draining it in the background. Install BetterBatteryStats and see what is using the battery.

How do you know your battery is getting worse if it's always charging?
My personal experience is the less you charge it, the better it will perform. However, when you DO charge it, make sure you are less than 30% battery and charge it to 100% before removing it.
For me it's easy, I basically charge my phone at night when I go to bed and that's it. I easily get through an entire day on this phone, though I admit I usually only have about 2-1/2 hours screen on time (I mostly use my tablet when I am at home)

I hope you dont do that for all your phones as it will destroy your battery way sooner. Charge it when it reaches 50% and you can do 3 to 5 years with the battery at 24/7 use. (Instead of the 1 to 2 years when draining the battery).

Yes, it is recommended to charge the battery when it below 40% and disconnect the charger when it reach 99%. Do not overchange.

There was a big test I did read and the best was to keep it between 40 and 80 percent.

Are you guys seriously sitting and watching until the battery goes down to certain percentage? And for what? Battery is easy to replace and not that expensive, it has a circuit to protect it from over and under charging, to avoid the damage and you get many more shallow charge/discharge cycles than deep ones as already mentioned. I charge my phone daily in the evening at my convenience, usually before I go sleep regardless of what's left (unless I use it so much it can't last until evening), so by the time I go sleep it's 100% and by morning it will be around 97% and normally last me whole day. I've been doing this for yrs and for example my 4yr old Nokia I gave to my friend, still lasts him couple days of light use on original battery. I wouldn't worry about it at all. Every few months you may want to fully discharge it to lets say 3-5% to have the meter calibrated and maybe clean the contacts with alcohol every six months or so, but that's all the maintenance my battery will get or need. If it fails before the phone, it probably had some factory defect or something, but no big deal as long as there is replacement easy to buy and with so many millions of notes sold, there should be.

That is good as a principle but the numbers are still rather big and depend even more on the charging current - if you charge (even) from 50% with 2000 mAh it will never last 1500 recharges - that is why Samsung has slightly improved the Note 3 recharging algorithm so as to use (variable) lower currents (even if the charger is 2000 mAh), and also why it is still far, far better to recharge from a very good USB at under 500 mAh (actually 450) - and indeed preferably from over 40%.

As long as the charging current is lower then 1C (1 full charge for the note3 its 3200mAh) its not a problem and wont shorten lifetime.
But yeah charging at lower currents is better, but more due to less heat and induction.
Anyway its just sad that other people with little to no knowledge about lithium batterys are giving advice, and WRONG advice at that.
Just read the link i posted in previous post (page1) there are the facts. Dont believe just anybody, people are stupid. (yeah im people too )
The chemical reaction will be less when battery is drained and is hard to recover.
But if the battery seems dead, put it in the freezer for 2 or 3 hours and it will be recoverable.
Theres more to these batterys than people think.

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

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
