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.

er.......what?

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!

Calibrating battery.

So i charged to 100% and callibrated and left the phone on the side for a while as ive heard battery callibration works better when battery is naturally drained. However, its been a week and its still at 100% -_____-. i dont plan on waiting a month or so just to make sure its perfectly callibrated. Is there a better way to do this? . Thanks guysss

Naturally drained? Regular use is needed to drain the battery. An unused battery (I have a couple) will take months to drain. Just use the phone as you do in your every day usage. Let it get down to about 5 to 10% then fully charge and calibrate.

you cant calibrate a lithium ion battery. in fact draining them is bad for the battery. however if youre having problems with the phone not reading the battery percentage correctly you need to wipe the batterystats.bin using either clockworkrecovery or just download the battery calibration app from the market.

yes for lithium battery it is. the older ni-cd batteries required this.
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
infact..this result shows that you should charge often. 10-15% discharge..and charge cycles provided the longest battery life.
this article is very very good!

That's good information. While I didn't know all that I did find the whole calibration idea a waste of effort. I've tried calibrating the battery on a couple phones and my battery life has never increased. The most that ever happens is I'll find myself away from home with no charger and have to quit playing with phone so I have enough juice left in case of an emergency.

No, Lithium-ion batteries do not have a memory effect.
Technically, you are not calibrating the battery, you are calibrating your phone's battery gauge. The easiest way to do that is with the Battery Calibration app.
1. Open the Battery Calibration app screen. With the phone on, charge to 100%, then let the phone continue charging for another 15 min.
2. Press the "Calibrate Battery" button on the app (deletes batterystats.bin), Close Battery Calibration app then TURN THE PHONE OFF IMMEDIATELY!
3. Disconnect AC charger
4. Remove battery
5. Wait 30 seconds, then re-insert battery
6. Charge phone with phone off for half an hour
This tops off the charge on the battery.
7. Disconnect charger and turn phone on
As the phone turns on it will create a new batterystats.bin and record the high battery voltage as 100% battery.
8. Use the phone normally and run it down to 0% when the phone shuts off.
The phone now knows the curve of this battery as it relates to your phone's ROM
9. Charge the phone for ten minutes, then turn the phone on and let it continue charging to 100%
This lets batterystats.bin know your phone's charging curve
10. At 100%, remove charger
Now use the phone normally. You will be happy to get an extra few hours use of your phone.
If you really want to get the most out of your battery, get the Battery Monitor Widget Pro app. It keeps a close watch on your battery and also allows you to change batterystats.bin files for different batteries.
And always remember to Give Thanks if you find this helpful!

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

bought it off Kijiji
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.
im qualified in lead acid. ni cad. nimh and lithium batteries. trust me..u cant hurt it unless you short it! !

How to make your battery last longest?

So I just got my galaxy s3. I haven't turned it on yet. But I heard that you were supposed to charge it fully and then let it die. Then charge it fully again and then start using it. That when. Doing this you will optimize your battery so it will charge faster, hold a charge faster, and just last longer.
Is this myth or fact? And if fact how do I do the steps so I get it right?
Thanks for the help and sorry for any mistakes it was typed on my phone that has aa small touchscreen.

Now is this ALWAYS the case?
To clarify what I am asking I am saying does it always harm the life of the lithium ion cell by letting die fully? Like even after 6 or 8 or 12 months of owing the phone (or any device), not just one the first charge. This could be very useful for further reference...:good:

There are some things can help increase life of litium batteries. First, don't let it go down to 0% as mentioned, keep not lower than 50%. Once per month it is recommended to discharge battery to 0% and then charge it to 100% again for device callibration.

This is a good question. I always thought that by discharging and charging batteries at full cycles, you would make their total useful life last longer.
In fact, this happened to me with a notebook, which I used to play with and charging at the same time. In the end, the battery lasted for a few minutes and I had to sell it.
But in all: is this really true? I would also like to know if is truth or myth.

This happened too (as funny as it is) my grandma. She would ALWAYS have her little nnotebook plugged in and eventually it drained. I found out because one day I took it off the plug a d it died while I was on facebook after around 7 minutes.
So I bought a new battery and now she charfes iit and takes it off the plug to use it and twice a month she lets it die and it has worked

It is true if you have a phone like Nokia 3310 if you do not have a NiMH battery do not do that you will lose time also you do not need to "format" a Li-Ion battery
read about lazy-battery effect on Wikipedia

rooting you phone to underclock/undervolt should also help out battery life pretty significantly ^_^

Lithium ion cells do not suffer from the "memory" effect as older rechargeable batteries. You do not have to let the battery run all the way down then fully charge it again to get the best performance that way, that was for the older types of batteries (again so you wouldn't get that "memory" effect) matter of fact its rather harmful to the battery to run it all the way down.
Charge the battery as often as you want no matter at what level it is. If you are going to do some high power **** (play a game, watch a movie) then plug it if if you have a charger around. The longer the battery stays at a high level the better for it. Try not to let your battery run your phone at a low state (charge it asap). Its ok to leave it on the charger even after its fully charged. Your phone and charger are smart enough to know when to start/stop charging the battery. This will ensure a long life for your battery.
...as for your phone...simple rules...if you are not using it( DATA, WIFI, GPS, SYNC, BLUETOOTH) then turn it off. Screen is the biggest battery drainer...KEEP IT ON AUTO!...darker themes really help alot...make your screen go off at 30 sec. or less. Have fun with your new phone homie.

[Q] Battery Issues

Hi everyone,
I've had my Sensation for about 14 months now and for the past month I've been having battery issues. Primarily, it's very quick to lose charge and will lose charge even while charging from the wall. First I bought a replacement battery but was still having the same issues. I've started using Better Battery Stats and Battery Monitor Widget but I don't have anything out of the ordinary running. In fact, not a lot is running at all. BMW has allowed me to see how the charging is going though which has been nice. During this period I have used Elegancia, Bruce's CM10, and am currently on ParanoidAndroid. All experienced the same issues.
Last night, for example, I put the phone on the charger at 16 percent. It charged up to 22 and then started the downward slide to death and I ended up waking up 35 minutes late.
Where do I go from here so I don't have to constantly be paranoid about my battery levels?

Sounds like you might need another battery. In better battery starts did you notice any unusual wake locks? This could drain a battery. But since it looses charge even when charging I'd think it was the battery. I personally was experiencing some battery issues myself finally I broke down and got a mugen 3800mah battery from mugen. It was expensive but really worth it for Me.with really heavy and constant use I get 20 hours out of my battery, with normal use I get two days. I'm also running paranoid Android rom. For me the big battery solved my issues. Only one draw back, it does make your phone thicker. New back included with battery. This didn't bother me much because of the excellent battery life I receive. Now I finally don't. Worry about battery. However it's expensive at about 95 dollars. But I was so fed up with poor battery life it was worth it for me. You have to be careful when buying inexpensive batteries because there are a lot of fakes going around. And the mah is not really what it says it is on the packages. You can test the battery and make sure it is what it's advertised to be. If you don't want to go with that large of a battery you can also try anker extended battery. It's a lot less expensive and is a good battery. I personally needed more juice so I went with the big battery. I know you said you replaced the battery but sometimes the bargain batteries go bad quickly. It makes me suspicious of the battery because it's even dropping while charging. This is strange. If you ruled out any apps or wake locks that might be draining the battery I would buy a good reliable battery. The draining while charging is a red flag. I'd say the battery is going bad. I don't at all regret my purchase of the big battery. It for me, solved my issues. I do Hope this helps and I wish you the best. Hopefully you will get your issue resolved soon.

its either an issue with the battery or the battery reporting.
Only thing you can really try is to charge it up to 100%, wipe battery stats in recovery, then let it empty totally and charge it up again, see how its behaving. There is a chance that its the reporting that is off.
otherwise this looks like the battery is on its way out im afraid

It makes me suspicious of the battery because it's even dropping while charging. This is strange. If you ruled out any apps or wake locks that might be draining the battery I would buy a good reliable battery. The draining while charging is a red flag. I'd say the battery is going bad. I don't at all regret my purchase of the big battery. It for me, solved my issues. I do Hope this helps and I wish you the best. Hopefully you will get your issue resolved soon.

Argh. I hope it's not the replacement battery too. I got a replacement HTC battery. The problem I'm having getting anything useful from Better Battery Stats is that rarely am I off the charger. In the settings it says I can log while charging but it may mess up the stats so I've shied away from doing that. I'm not against getting a bigger, better battery but I would hate to do that and have it actually be something else hardware-wise where I would need to get rid of my phone.

its either an issue with the battery or the battery reporting.
Only thing you can really try is to charge it up to 100%, wipe battery stats in recovery, then let it empty totally and charge it up again, see how its behaving. There is a chance that its the reporting that is off.
otherwise this looks like the battery is on its way out im afraid

I'll give this a try if I can get it back up to 100%. Is the reporting in Recovery always correct? The battery never has issues charging while it's in Recovery mode. If that's the case then I'll charge it to 100% in recovery and then wipe and start fresh.
Thanks

I don't think it's the battery. This phones have errors in battery readings. I feel your pain man. Mine is from T-Mobile (Sensation 4G) and it discharges if I use it even at lowest brightness when it's charging too.
If I reboot, I get the battery boost. I have tried EVERYTHING I read here and nothing worked. I even have 4 batteries. All of them in good condition.
I even tried three times discharging it fully and without turning it on, charge it in the night and when I wake up 7-8 hours later, it's still charging. I tried wiping stats, changing ROMs, changing the usb cable and the charger. Everything... I believe it's a hardware issue. (Thank HTC for that) I'm not buying another HTC when I have to upgrade.

Interesting...so if you were to charge the phone in recoery how long do you think it would take to get to 100%?
I would definitely do what you said, charge in recovery then wipe battery stats and go from there.
If you're interested in having something to compare to, it takes my phone about 3 hours to charge to 100% (by the way I'm using an Anker extended capacity battery), with a peak current usually around 800 - 900 mA. Fully charged I have somewhere around 4100 mV. If you haven't already, I'd suggest adding a Battery Monitor widget with mA, mV, and % available being displayed and it will be pretty easy to get an idea what's going on.

I'm leaning towards hardware issue too. That's why I figured I'd post and see if there was anything else that I can try. It's also why I don't really want to buy an expensive battery since who knows what it'll fit next. I know what you mean about the reboot battery boost. You can almost gamble and bet on percentages when you reboot. I've seen 50% swings before.

In recovery I would guess that it wont take very long to charge to full. I have battery monitor widget installed and while plugged into the wall with my 1.0A charger, it will typically pull 100-200mA but sometimes it'll spike to 700-900mA. No rhyme or reason. When idling and functioning properly, without a charger plugged in it drops 9-100mA. Sometimes though while charging it'll sit at negative 100-200mA.

HA! Just rebooted my phone and it went from 68% to 100%. So I rebooted into recovery, it also said full so I wiped stats.

I normally get 2 to 3 mA drain with the phone sleeping. When charging you may not necessarily get close to the 1 A current delivery of the charger straight away, typically it will ramp up over time and reach peak charge current as it gets closer to 100%. Once at 100% it wants to just "trickle" charge to maintain 100% charge until the charger is disconnected, so any wakelocks etc. that cause a current drain during that "trickle" charging will actually decrease battery charge until the charger ramps up to compensate for the drain. Random spikes in charging current would suggest a hardware problem where the electronics are struggling to properly govern the charging process, as would a large negative current drain with the charger plugged in. Silly question but what's the actual plug connection to your phone like? Nice and solid, pins all OK?
