Does Your Battery Charge To 100%, If Not Where Does It Stop?

ive been a nexus s user for almost two days now and i noticed that my battery level stops at 96%. is this normal being as though gingerbread is up and coming and this is the first phone to have it? also i seen a thread on here that shows you how to push your battery to 100% but i also read that the phone may overheat.....im not too sure about that. i have done 2 charging cycles by killing the battery completely and recharging. with my heavy use that i did i got 7 1/2 hrs use. is that normal or is that bad? are there any tips and tricks or will there be a hotfix launched in the near future. thank you for any comments an questions.

See my post in the Accessories forum. The only way to get a true 100% FULL charge is to charge the battery via a wall charger. Since I bought a wall charger and couple extra OEM batteries on Ebay, my battery is lasting significantly longer.

What happens when you pull the cable out? Does the battery immediately drop to 97%? Since it likely does, then it's not truly charging to 100%.

That's what everyone's does and why I pointed you to my post. Get a spare battery and a wall charger and charge your batteries to a true 100% like I do. They last WAY longer.

[Q] full battery charge only reaches 98% after 8 hours

Hi i dont know why my battery isnt completely charging! or the battery charger info is broken! anyone else not charging to 100%?

It probably hits 100% then starts draining slightly to keep it from over charging. Mine gets to 99% then I unplug and replug it and it hits 100. But that has happened with a lot of devices for me.

Happens on my evo as well. You can get around it by flashing a kernel that does trickle charging which I'm sure we'll get for the tf sooner or later.

I would NOT use an sbc kernal on this battery, they are known to shorten battery life. Cell phone batteries are a dime a dozen, this thing is both non-user replacable and most likely not cheap.

Pretty sure its a lithium ion battery inside and you shouldnt overcharge those. You're best off keeping it between 30-90% and doing a drain and full charge once a month to prolong its life. The charger should stop charging when the battery is full on it's own anyways if you do leave it plugged in. I think it's a European law to have that as a safety feature, probably an American law for this too. So if the charger is staying hot a few minutes after your device has hit 100% charge, you've got a problem. Mine does get to 100% but yes it takes a while to top up, that's just the way these batteries operate.

So whats the best method for a first-time battery charge?

Do i let the phone shut off from the battery reaching 0%, then charge it to 100% and be on my merry way?

I've read multiple theories, but I think u should take it down out of the box, then shut off and charge to full...I remember ASUS recommending that to a media outlet when the Transformer 300 came out a few weeks ago...so that is what I am going to do when I get mine.

Thats exactly what I did, I let mine completely die and then charged to 100%.

Be careful with how you charge the phone, rather with how low you let it get.
Depending on how technical you want to get about it purposefully letting a battery drop to absolute zero can cause some odd chemical reactions that while not immediately evident can some times shorten battery life.
I would recommend taking it out of the box and using it until it is low but not dead. Maybe 10 or so percent and then either turn it off and charge it or leave it on and charge it just do not pull the plug on the charger until it is at 100%.

This.
Full battery cycles are not good for long term life of Li ion batteries.
Also, its unlikely, but occasionally happens where discharging the battery to shutoff will render the battery unable to take a charge. The safety circuit on the battery is supposed to prevent this, but its not failsafe. I've seen more than a few reports on previous HTC devices where this happened. And since the battery on the One X is not easily replaced, the result can be disastrous.
The battery meters on phones are not very accurate in the best of circumstances. No need to drain to shutoff, 10 or 20% is fine. No value added to draining to shutoff, and the consequences can be very bad.
Drain to 10% or even 20%, charge to full, repeat 2-3 times. This is done just to calibrate the battery meter on the phone. Its a misconception that you can somehow increase battery life by "conditioning" the battery. But modern Li ion batteries do not suffer from memory effects, and conditioning only works for older tech NiCad batteries.

I do the same thing for all of my phones.
1. Activate and mess the heck out of it until it dies completely.
2. Charge it up to 100%
3. Mess the heck out of it again until it dies completely.
4. Charge it up to 100%
5. Mess the heck out of it again until it dies completely.
6. Charge it up to 100%
Then use it normally

How do you tell if the phone is charged to 100% while off?
While on, my battery percentage doesn't seem to go past 99%. Is that correct or is this last 1% just taking a very long time?
Update: NVM last 1% just took forever. LED does turn green when fully charged.

The LED will turn green once it's 100%.

Don't worry about letting the phone die and charging it up to 100%.

Mine came dead too. Charged it to 100% and now been using it and so far have 36% on 3h 9m on battery.
Screen at 84%
Does the battery life get better? Because it seems to be draining rather quick. Even though I have screen brightness less than half.

@Maroon Mushroom, Correct these lithium batteries dont have memory effect, but over discharging them will shorten its life.
I dont want to sound like an expert, but discharging the battery until it dies is not recommended. It will affect battery life/performance.
A couple of good references here: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
http://batteryuniversity.com/learn/article/discharge_methods
http://batteryuniversity.com/learn/article/how_to_charge_when_to_charge_table

Ya, we use Lithium Ion (Li-Ion) batteries now which dont have a memory. The older Lithium Polymer (Li-Pol) batteries did have a memory and needed a certain charge method to get the longes life cycle out of it.

Awesome, thanks everyone
I turned it off at 20% and wen't to go buy my MicroSIM (ugh...) cant wait to play with it tomorrow

Why would you buy it? Pretty sure they would give one to you for free

It's offered by Rogers, but i'm on Telus

Hmm, i hate the idea of letting it die completely. But what i've always done is turned everything on and ran it through a low-powered usb source so it has a charge but the battery is still draining. So even if the battery runs dead it has power via USB plug [make sense?]. Usually having everything on [i do mean everything] and downloading a torrent so the internet is constantly under use. Then again i'm not sure how the One X will work out for this, but thats what i'm planning .

guys its lithium...u cant drain it to 0...even when android shuts down your at around 3.6volts. thats definetly not 0volts. no memory and android wont let you ruin your battery...so charge however whenever.

Charging time

I find this tablets charging time so annoying I'm coming from a zoom with charged so fast compared to my note
Sent from my GT-I9300 using xda app-developers app

Not trying to sound mean, but what's the point to the thread? Is it a question asking how to improve charging times?
BTW, I have a Xoom and I think it's just that it charges a lot faster due to the special charging port.

It will charge much faster if you connect it to 220 volt power sources, rather than 110.

Well I wanted to point out that it is an annoying factor for people to think about when considering buying the tablet but I understand your point

Ummm... wall voltage won't affect it. The device only takes in 5v regardless of the where you plug the charger.

Is it just me or do you guys think its slow charging
Sent from my GT-I9300 using xda app-developers app

up to 90% it seems pretty decent. it's that last 10 that seems to take forever. I think the last time I charged it I went from 30 to 90 in 2hrs then the last 10 took another hour.

I ran my note into the ground today and then started a stop watch to see how long it would take to fully charge it. 4.5 hours!!!!
Mine takes way too long to charge also!!

Charging a battery faster leads to more heat which reduces the life of the battery. A very high capacity battery will take longer to charge, all else being equal.
They could have sped up charging by using a non-standard supply voltage/current from the charging cable (like ASUS Transformers, which uses 15v instead of 5v) and thus charging the battery faster. But it would have just got a bit hotter which is not good for the battery.
The battery stores many times more energy than a smartphone battery, yet it only takes about twice as long to charge. I think that's pretty decent.

Given the battery's capacity (7000+mah) and the charge rate (around 2A) I'd say the charge time is right around what I'd expect.

I found the charge a bit slow aswell, but the battery last so long that it balances things out for me, i was disapointed at first until i realised how well the battery performs, regardless what apps i used.

Yeah, Im not too worried about the 4.5hour charging time, my battery lasts me a few days and I can always plug it in before bed and wake up to a fully charged tablet.

I use my tablet during the day and before I go to bed I put it on charge and it's full in the morning. Do some people use their tablet so much in the morning it's out of juice by the afternoon? Give your fingers a rest. My battery lasts me usually all day. Even with looking at YouTube etc.

Slow charging after last firmware update
When I went to bed last night I had 19% power left. Like I normally do, connected my Note to charge overnight. Woke up 7 hours later to find that it had only charged up to 49%. Within 5 hours from a depleted battery, I usually have a full charge. Any thoughts as to why this is the case?

My galaxy note 2 charges faster than my note 10.1. But I have no problem with it.

I just bought my note yesterday, and I have to admit I was so surprised when I charged my note. It took 4hr to go from 7% to 89%. My previous Asus transformer tf300 can go from 0% to full charged in 2 hrs.( Not really big deal but it will be better if Samsung includes high voltage wall charger .

It sounds like you may have charged with your note 10.1 turned off.
The note 10.1 like many other tablets needs the tablet to be on while charging so the tablet can regular the rate of charge.
My Note 10.1 charges much faster turned on with WiFi, Sync and GPS disabled.
Mine goes from 25% to 100% in about 3.5 hrs.
from 90% to 100% takes about 45 minutes.

So do I (hello, fellow convert! ) and the real reason the Xoom charges faster isn't the port, it's 'cause the charger is 18W and is of a higher voltage (12v/1.5A vs. our 5v/2.1A). (I guess it could be argued that they had to go to a different port to not violate the PDMI spec the Samsung units use, though.)

You're being funny, I hope - our charger (just like any other charger released in the last decade) is a Universal Charger (100-240V/50-60Hz) so in any case the output voltage and current is the same no matter where in the world you plug it in.

That's not really true, though, as our tablet is in fact on when you're charging it- if you tap the power button when it's charging in the "off" state, you'll see that battery animation, and that's in fact a fully-running kernel but instead of running "Android" it's a special run mode more like a Recovery. The kernel is in fact running and alive.
FWIW my tablet charges far faster when off vs on, as there's far less simultaneous drain on the battery. Not sure what's going on with yours.

Back to normal

I hadn't completely shutdown my tablet since the update last week. I did so yesterday and now charging times seem to be back to normal. Something new from the update I noticed, when batery gets somewhere around 20% left, the battery indicator changes from green to yellow.

My tablet gets about 10 hours on battery, or more if im just reading the web. The most intensive app I run is candy crush and s-note.
That being said it seems to charge quickly, in about 3 hours. My complaint is the short charging cable it shipped with.

How do you handle your battery on a new phone?

Just curious how you handle this, because everybody says something different:
First use: completely charge the battery and then complete discharge, or first complete discharge and the full charge?
I also remember someone telling me that you shouldn't let your battery run completely empty, is that true?

just charge it when it needs it, dont worry about what % its at, and dont worry about running them right down... the phone will power down before it gets to a dangerous level for the battery.
dont leave it plugged in all the time when its sat at 100, dont leave it down at 0 and just forget about it for weeks on end...
thats all you need to know

I don't buy the bit about wireless charging. I've used my Nexus 4 with an LG wireless charger daily for almost a year now and haven't noticed any side effects with battery drain or overheating. In fact, I'd argue that the Nexus 4 and my Nexus 7 get hotter when plugged in than they do on the wireless charger. I have absolutely no reservations about using the Nexus 5 on my LG wireless charger when it arrives this week.

Well the charge and discharge isn't necessary, IIRC that's only for older battery technologies like Ni-Cd batteries (Nickel-Cadmium). On the other side, you probably shouldn't let it discharge all the way since these are Li-Po and it could shorten their lifespan (apparently).

I just plug mine in whenever I'm near a charger.
I'm at work at my desk... its plugged into the charger.
I'm in my car... its plugged into the charger.
I'm at my girls house... its plugged into the charger.
I'm at home replying to xda / android central posts... its plugged into the charger.
This is what I've done with every phone I've had. I only had issues with one battery. I used to have sprint and I had the Samsung Galaxy S2 Epic 4g Touch. After about 8 months the battery got fat (they said it was called a swollen battery at the sprint store) and it kept turning off. They gave me a new battery at the sprint store and I continued with my routine above and never had any other issues with it or any other phones.

this is right on both accounts. you dont need to discharge it all the way, and doing so will reduce its life a little. i recently read about lithium poly batteries and the particular blog i was reading talked about running the battery down to 20% then charging it to 80%
i think when i first get the device i will use it down to 0%, charge it up to 100% uninterrupted and then hopefully keep it within that 20/80 range and probably doing a 0-100 refresh on the first of every month

If you guys want to read some in depth material on charging lithium batteries I would recommend reading this. Very informative.

It's fine. Phone manufacturers know that people charge their phones overnight. That's why there is a trickle charge mechanism built into all phones nowadays.

u have to calibrate the battery too

Over the last month I've had somewhat of a binge of buying phones from Amazon and returning them for one reason or another and I've noticed that the first 1-3 days of phone ownership are usually the toughest on the phone / battery.
I've owned over the last 2 months (in order):
- S4
- HTC One (x3 as 2 were faulty out the box)
- LG G2
- S4
- N5
I've decided on the N5 as being the best for a number of reasons, but my favourite is price.
I havn't worked out whether it's a combination of new phone = more usage or new phone = requires battery calibration. But the N5 is the only device out the major players that actually made it through day 2 (the day after it came out the box) without a charge midway, infact it's ONLY JUST gone on the charger after some 28 hours of moderate (3 1/2 hours screen on) usage.
My gut feeling is that once you're out the first week just use the damn thing, but the first few charges can make a difference to how quickly the battery feels calibrated. My N5 came with 50% charge out the box, I ran it down to 0% and topped up charge as much as I could the first day. Once I got home I once more let it 0% and then did a full 0-100% recharge. Then my 28 hour experiment started and now I'll just use it as normal, and not worry.

I keep brightness at 50% to enjoy this beauty and I do not give a single **** about the battery.

Charge battery between 20% - 80%
Do not use phone while charging
Unplug charger when battery full
