how to take good care of you batt

good read as it seems many still maltreat their li-ion
acording to old ni-cam myths

Also, make sure you read http://wiki.xda-developers.com/inde... revolutionary, comparative, numeric results!

I've always said this simple statement about LiIon: Charge early and often.
Do you need to plug the phone in every time you get off a call? No. Do you need to worry about it dropping below 80%? No. Just charge as often as is convenient. Sitting at a desk for a hour working on something? Charge. Driving for more than 15m? Charge.
I think if you obsess too much you might wind up with USB connector problems from all the cycles on the connector itself, but intelligent use of the above statement should get you the most out of your battery.

i believe that you have to charge your battery all the way full then use all the power until it dies then you can charge it back again
but not sure

conditioning the battery the first time you get a new phone also helps, alot of us just charge for a while them use it. all my phones i let them charge for a full 24 hours right after i get them

My battery only last 6 hours

Ugh, why don't people read the article BEFORE they comment?

Ehh, doesn't the charger uncharge when the battery is full? Like a safety thing?

Some articles say that one battery life cycle is used up everytime when a full charge is done. Other articles say that one battery life cycle is used each the battery is connected to the charger.
I have not seen one article that shows the truth with facts.

No offence but I always found this to be stupid reasoning.
What if you leave home with a quarter full battery and you get caught in the middle of a natural disaster (earthquake as an extreme example) and need to keep in contact with rescuers after being stuck in a building for 2 days?
Personally, I always charge my phone/laptop whenever convenient.

The only problem that your battery lasts only for 6 hours is due to too much charging...So when you will buy a new battery then make sure that only charge your battery when it will remain only 10%...And try to charge your battery with phone switched off..

Charge little and often, try to avoid deep discharge/charge cycles.
Back in the days of NiCd batteries there was the posibility of memory effect where if you didn't do a discharge/charge the battery wouldn't hold as much charge.
NiMH batteries do not suffer this, but discharge/charge cycles were required because when they started being used very few people had smart chargers so had to discharge to be able to time when to stop without overcharging, and also due to confused information pulled over from NiCds.
Top up charges are better for them too.
Lithium batteries also don't have memory effect, and are better off with top up charges.
Ask yourself this:
What would stress the battery more; running 1A through it for 10 minutes or 1 hour?
Also, as the battery discharges, its voltage drops so the current drain has to increase to compensate, discharging the battery even quicker (remember how capacity graphs drop off quickly?)
Say your phone needs 2W to run, with a 4v battery that's a drain of 500mA (P=VI)
When the battery has dropped to 3.5v then to produce 2W it takes approx 571mA.

batt problem
how to keep my batt good?

I've always just charged my phones overnight while I sleep. Never seen ill effects. If I don't make it home that night my phone still lasts through the next day.
It's not like that battery is irreplaceable. Go get a new one if your battery is nearing the end of it's life. By then you would have probably moved on to a new phone.

skimmed a few parts, but thanks for the read mate, learned tons.

as others allready mentioned, there are many different suggestions how to take care of the battery. I usualy reload the baterry only if the capacity is <= 5%, without unpluging it before it reaches 100%.

thanks for the info!

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%.
These batteries don't have a "memory" like older phones

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.

Takes way too long to reach 99% from 95% charge in power adapter

Hello everybody
I hope this to be a common problem. I
I charge my mobile phone via 1amp 5v charger,
Even then it easily takes 10 to 12 hours for the battery charge to reach 99%.
It reaches 95% charge rather quickly.
I expect the mobile phone to take only 4 to 5 hours to finish charge completely.
Please suggest some solutions to achieve that.
If my mobile phone charger reach even 99% it makes a world of difference in battery life.
Sent from my Nexus S using xda app-developers app

It doesn't actually charge above 96% to prevent overcharging. Anything above that you see is faulty reporting.

^This. Mine charges to about 98% most of the time. What's weird and something that hasn't been answered yet is why the phone never charges to full if I leave wifi on but if its charging with just data on, I'll get a full reading.

I read the linked page completely and quite understand the logic.
But, even then my mobile phone's battery reaches 99% if left for very long time.
At the same time, the battery drains slowly if it reached 99% charge.
Yesterday my battery % was 38% at 8 PM.
But today, it reads 20% at 6 PM.
Yesterday i disconnected the mobile phone from wall charger after the battery % reached 99%
But, today i disconnected it while the battery % reading was at 95%.
You can say that battery gauge is lying to me.
But at the end of the day, the mobile phone would be switched off by Battery Gauge's instruction and not by my instruction.

It's called bump charging. Charge your phone to max with the screen off. Then charge the rest with the screen on (I recommend enabling the keep screen on option in the developers section of your phone for that). It will charge to 100%, and not only for cosmetic.
This has 2 sides. It will give you more battery BUT it is not good for the battery in the way that it makes it deteriorate faster. Thus if you plan on keeping this phone for a few years, you should likely not bump charge it.

Storing or charging Lithium Ion battery at the maximum capacity promotes corrosion, deteriorating the battery's lifespan.

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.

A question about Zerolemon's Extended Battery.

Hello guys! So I just bought an extended battery from Zerolemon for my S5.
My question is, should I charge it for 12 hours before prior use like the manual stated? Or fully discharge it first before charge as some reddit folks suggested?
Thanks!

Like manual say

After first full charge, run it down to 2% like it also recommends. Help to condition battery, I do it to mine once in a while. Have this one for almost a year now and it is working quite well, can't say there has been any depreciation to run time yet.

Which app is this ??

That is correct,
I may be mistaken as I don't have the little instruction sheet., but there is some additional time in hours after the phone says it has reached 100% full charge that it needs to remain connected to finish "topping" of the battery. Although I would argue that it is almost impossible, given that any algorithm the phone uses to charge one brand of lithium battery vs. another hasn't changed when the battery has been swapped out, and charging should stop once the phone see the correct internal voltage. Yet ZeroLemom recommends to leave it to charge.
The final ~10% is quite misleading as far as how long it will stay on before it finally turns off due to low voltage cut out. I had mine running for over a day and a half sometimes before it finally turns off. Very annoying that low battery message, would have liked to know a way to change the notification, or either actually entering a new mAh rating in the ROM's data so a more accurate approximation of useful charge still remaining can be properly calculated/displayed.

Hey so I got it last 2 days ago and it on its way to its first discharge now. Should I fully let the battery drain to 0% or just charge it when it hits 1%? What would you do?

It's really up to you, I would at least reach the 2%. Any further past that point may or may not matter. I've let it go before until it turns off on its own, but like I said in a previous post the low battery warnings drove me nuts.
