Can I recharge the battery every day?

There are lots of myths regarding lithium batteries.. some say you are not supposed to overcharge it (charge it only when it's running out)
Some say it doesn't matter since lithium can be recharged as much as you want and it won't deteroriate the battery's life.
Which one? Can I recharge my Touch Pro 2 every night before I go to bed and leave it until morning? or should I do it when it's running out to preserve the battery's life?

You should keep the device on A/C power as much as possible. So, it's fine to charge daily overnight. Every once in a while, you should let the battery run all the way out before recharging. What this will do is keep your battery meter reading accurate. If you don't do this, eventually, your device will "think" it has more juice than it actually does.

Ah thanks
So to cut the story short, recharge it as much as you can and prevent the battery ever from being run out

Nahhh, not fully true. Somewhere else on the site of batteryuniversity it sais that completely discharging the battery will reset it's memmory. This is usefull after a lot of charges and discharges (in the beginning, I think they already did this (you may hope).
(the memmory helps the battery know where his power is storaged and how much power the battery has left. But doing this frequent speeds up the battery 's lenght of life

In my experience
Enjoy your device and charge battery when needed/desired
Use it normal
Batteries have a duration of 3-4 years aprox, no matter if you charge it every night or leave it till it´s empty...
When battery fails you buy another one and so on
Just my opinion,

My experience with the battery life on my touch pro 2 is that I will keep the phone usually docked in my cradle on my desk when working so it's always on charge. When I use my battery I wait till it's about 40-30% drained and will stick it on the cradle again.
When I'm in my bed ready to sleep, I use the normal charger and leave it on charge over night.
Still experimenting though.

Do you have a cradle for your Rhodium ? Where did you get it ?

Check my battery thread, it will tell you pretty much everything about li-ion batteries and taking care of them

Hmm, first of all Li-ion batteries have NO MEMORY unlike NiCd batteries. You probably refer to resetting the reading gauge - which is related to device's capability of getting accurate reading rather than battery itself. It is recommended to let the device die once a month and give it a full charge to "recalibrate" phone's battery meter (not the battery).
But you should avoid hitting 100% battery mark as well as going bellow 30% as much as possible.

from my experience as a phone shop owner and owner of many many phones i always advise my customers and friends as follows:
1st charge 10-12 hrs. allow battery to fully discharge
2nd charge at least 8 hrs
after 2nd charge you can charge and use as you want. the initial 2 charges kick start everything and starts your battery cycle on good stead
never had any complaints!

Another thing, is it bad to use your device whilst plugged in?

The battery should be as cold as possible when charged. So if you are using the phone the battery power drains and is charged at the same time. Therefore it gets warmer than without.
Best for the battery is to be charged when the device is switched off completely.
I wouldn't consider that much of a problem, because you have bought the device to use it and not to live in fear that you treat the battery right

when plugged into USB and playing a game on my TP2 I got the message the device is using too much power, and it drained the battery even though recharging via USB. No problems when using AC adapter though.

Used my XDA Orbit 2 for 2 years now, and mostly charged at free will. Battery is still fine, so no special charging rules for me...
I noticed though, that charging over USB takes quite some time while charging over AC cable is done within an hour or so. When looking at my AC it has 5 Watts of output power, while the USB only has 2.5. That would explain your issue with the battery running out even when having the USB cable plugged in.

Last full charge status = Not applicable???

I got my Tilt 2 yesterday. I charged it to 100% before using it, then had it on all afternoon setting it up and adding programs. I charged it all night, but when I got up this morning the battery said 70%.
I went to the power settings and noticed there's an information tab that has status info since the last full charge. The status under Last full charge on my phone said "not applicable". I plugged it in at work this morning and waited a while to make sure the charging light turned from orange to green. It did and the battery power remaining was 100%. I left it charging another hour.
A little later I checked the information tab again. It still says Last full charge: Not applicable. HUH???
Aside from the Last full charge field, it also has stats for Standby time, Talk time and Device usage since last full charge. Since I apparently still haven't had a "last full charge" all the values are 0 on my phone.
Does anyone else have a date and time in that field on the information tab?

i got the same on my imagio.

When I first got my Tilt 2, I noticed that screen and thought "hey that's useful". It had the values all filled in properly. But when I went back later to check it, I saw "Not Applicable" just like you. It seems to be intermittent though, because I checked it just now and it has good data. I haven't noticed any correlated factors that predict whether the info will be there or not.

you should never leave your phone plugged into the charger after it has reached full capacity. you're basically draining the overall battery life of the phone, so it won't last as long off of a full charge.
did that to my old tilt before I found out about the overcharging thing, and had to use my warranty to get a new one since the phone would shut off by itself at 90%+ and turn back on again with >5% battery power left

I wasn't really sure that it was fully charged because of that stupid message about the last full charge not applicable. Thanks for the information. I didn't know that it was possible to ruin a battery by overcharging it.
@enisoc,
I thought it seemed like it would be a useful feature, too. Every single time I check power settings the values are null. It's interesting to know you've seen data there at least twice.
ETA: Now that I think about it, for the last two years I've plugged in my Tilt before going to bed and left it charging all night. Every morning it was 100% charged and I never noticed any adverse effects.

Maybe I've just been very lucky, but I have had a Sprint HTC Touch and before that a Samsung Blade (razr wannabe), each for two years. Every night for those four years, I plugged in my phone before going to bed and left it there. I have always had great battery life on both phones.
Specifically for the TP2, I have read that it stops charging at some point when it's done, and won't trickle even if you leave it plugged in. This has been reported by various people because they find that if they leave it plugged in for very long times, they'll end up with only about 95% battery, because after the first few hours it was no longer charging.
Perhaps less convincing, but also interesting, is the fact that (when it works) the "last full charge time" on my TP2 shows up as a couple hours after I went to bed, rather than the time when I unplugged it in the morning.
YMMV

oh wow really? that's interesting. that would be nice if it's really true. what I've been wanting is an app that allows the phone to make some sort of noise (i.e. an alarm sound) when it is fully charged. just to let it's owner know that it's finished and so it won't get overcharged. I think i'll go request it at development n hacking.

I am 100% sure that you cannot overcharge a TP2, in fact I would say any phone or device with a Lithium Polymer battery.

..........

it's true, once the TP2 hits 100% it stops charging the battery & the usage time will kick in.

Day 3 and still no data in the battery power information tab.

do a hard reset. mebbe itll work.
Since its very new, you got nothing to lose.

flip, do you have a TP2? If so, does that tab give you data all the time?

yes, its a Tmo TP2.
it worked on the Stock rom.
I have a custom rom now, and it works as well

once the green light comes on on the touch pro 2 u it stops charging, u cannot overrcharge it

Not only can you not overcharge the lithium Ion batteries it is actually better for them to be recharged as often as possible.
Menneisyys wrote a great article on it a while ago. This confirms what I have always been told.
http://forum.xda-developers.com/showthread.php?t=342162&highlight=battery+charging

Overcharging li-ion (and li-po) batteries results in catastrophic failure, a.k.a. explosion. Therefore, chargers for these battery chemistries stop charging when they're full.

Something is wrong with ne WM6.5 driver!
Yesterday my battery duration was about 24h (with 6.1 i charge it every 2-3 days!)!!
I fully charged at midnight and now, after 15h it says 90%... It's a little bit strange!
At midnight i could see battery stats.. Now it says "not applicable".
I used Dr SigStat and it says a temperature of 2,47°C!!! (in WM6.1 temperature was normal).
What's wrong??

Over the weekend I finally got some data on the information tab. Either Saturday or Sunday morning when I checked it gave some time around 5AM as the last full charge time. Now it's back to Not Applicable.
@D J Palmis,
I wonder if anyone knows the answer to the 6.5 battery dilemma. When I was using a cooked 6.5 ROM on my Tilt I was getting normal battery duration. My battery life on the Tilt 2 is comparable to my old Tilt.

i see this on my tilt2. battery info shows up, with idle/usage times for a short while after full charge (green) if i check after a few hours, it goes to n/a. looks like a driver bug to me.

New battery & how to condition it

I'm ordering a spare battery; what is the best way to give it it's first charge / how should I condition it?

I don't think a lithium ion battery needs to be "conditioned" since it does not have the "memory" effect. It's usually the battery stats on the phone that can mess up the reading.
I would probably just make sure it is fully charged when switching them to be more accurate. But, I'm no expert...

Thanks for the reply.
I'm fairly sure I'd read somewhere that it should be fully charged before turning on the phone for the first time & after that do a couple full cycles (full-empty-full) etc..?

Yes, a full charge before using is recommended (I've also heard to let it sit on the charger for a couple more hours after it is charged helps) and maybe a few full "cycles" after that. But, like I said, I'm no expert and I, personally, have had no issues with my battery

True, it's not for the battery but for the phone stats. Lithium ion batteries are fully conditioned at the factory before being sent out. It's the last step in the actual cell manufacturing process.
Yes, I work for a lithium ion battery manufacturer. We make larger cells (not the tiny ones in a phone battery) but I have contacts and friends that work for other manufacturers that do make the little ones and they're basically all the same.

i ordered too 1800mah batteries cause i couldnt find any 1950s...they both arrived dead i waited 30 mins to charge and turn the phone on, and the other one is extremely dead it shows charging for a few minutes and then the red light turns off
so far the one i charged to 100% isnt working how i would have liked it dropped to 50% within a few hours and i charged it to 100 again and it dropped to 80 very quickly im gonna let it die tonight hopefully i get them to work good

Sorry about your bad experience.
Don't know what you purchased or the vendor, but I purchased a 3200 mAh batt from Siedio and am quite happy with it. I've been using it for over a month and get heavy use of my Atrix. High quality batteries are not cheap. Don't get the $20 dollar specials. (I have no financial interest in Siedio, I'm sure there are other vendors with quality batteries).
Battery calibration has been a challenge but I think I have a solution. I'll know in a few days as I'm presently recalibrating. It would have been so much easier if Moto had added a 5 cent current sensor to the phone.

I wouldn't worry too much about conditioning it. Just use it like you regularly would any other battery. Most horrible battery life comes from the way Android handles the battery stats. In my experience, most Li-ion batteries seem to really get their most effective use cycles after about a week or 2 of consistent usage. If you're experiencing some really drastic battery drops though, that's when it may be time to recalibrate the battery stats or start questioning the rom/radio/kernel that you're using.

Yep. However, unless you're impatient, charging it to full shouldn't do you any harm

For Lithium ion batteries, I've always put them immediately on the charger, let them go to 100%. Then unplug and let it completely die (that is, let it get so low the phone turns itself off) without pluging in. Then charge back to 100%. After that, use as normal. Doing this has gotten me long battery life, both short and long term compared to others I know who dont do that.

When I bought my phone the Bell representative said to fully charge then discharge the battery. I thought that you aren't supposed to do this though because Li-Ion batteries lose some of their maximum life when you do that. Only Ni-Cad batteries needed conditioning like that.
I could be wrong though. Would be nice to know proper procedure for this kind of thing

You're right, lithium ion batteries should not be fully discharged but it does help the first time to get the battery reading accurate. After that just charge whenever. It only really becomes a problem if you let it go dead too often.

+1. There's two reasons store reps tell you to discharge and charge the battery at least one complete cycle before using the phone. The first is that they're stuck in the past and think li-ion tech is the same as NiMH. The second and more sound reason is that it helps to set the battery statistics. If you're one of those people who loves to mod their phones right when they open the box, you could theoretically bypass this step by rooting and charging to 100%, and then just doing a manual battery recalibration by wiping the battery stats.

Yeah - if these are the Chinese jobs that came with the charger on Ebay, I got them too. They drop REALLY fast down to 5%, then I get at least another 24 hours out of them. It's crazy. I have tried to recalibrate by removing battery stats, but these haven't gotten any more accurate in several full charge / discharge cycles.
I suppose I will use them as spares, and just understand that the meter is not accurate on them. I still get a minimum two days with these cells. Will see how long they last. With batteries, you do get what you pay for.

Best advice for sharging battery for first use out of box?

so what is the best thing to do?
is there any way of charging,dis charging ect to get the best battery life?
or should i just charg it to 100% and use it right away?
i did a charging squence with my nexus s. but duno about the Gn.

for me is to turn on the device and start working until the battery drops to 0-1%.
only then im charging it X2 then needed to go to 100%, you can make it Double if you want.

Well, this is going to be one of those threads where everyone has their own little way to care for a battery and others say their way is better, etc, etc the arguments breaking out which will result in people posting www.batteryuniversity.com in an effort to win said arguments.
Here's mine. On a brand new phone, I put the battery in, boot up, connect the charger, run it to 100%, disconnect charge, run battery all the way down, connect the charge, run to 100% and go about my life charging when I need to.
My two cents. Have no idea if it does any good, but my SGSII is going on 1 day 14 hrs on a single charge, so it must work somehow...

My way,
Turn on phone, charge it to 100%, leave it plugged for an extra 20 min, and start using it normally.
The only time I discharge a battery is after a couple of months. Because we never charge it to 100% and they start creating memory and charging less and less every time. The purpose of discharging it completely is to erase its memory. That's why when it is new, I see no point on discharging it completely. Batteries suffer every time they are completely discharged and if they are left 100% for a long period of time, thats why new batteries always come charged about 50%, to extend battery life since they may be stored for a long period of time. (ref. aviation school)
Just my 2 cents.

That hasn't been true since NiCd's in the 1980s.
Modern Lithium-Ion and Lithium-Polymer batteries have no "memory" and are actively damaged if allowed to discharge fully.

Generally because they don't know any better and they don't realise battery technology has moved on.

Because batteries "back in the days" were quite sensitive to memory. That's why we were all raised by the complete-discharge-mantra, which sticks with you forever. The next generation won't have this problem and will feel free to charge their phones when they want to. ;-)

Becouse android in itself keeps a battery log, it is from this log your device calculates the amount of battery you have left. To keep these values true (calibrated) you should do 2-3 cycles where you on purchase, discharge fully until device auto shut down, start it WITHOUT charge a couple of times and let it die to set the min value, charge up to 100%, use your device again till auto shut down... you dont have to worry about damaging your battery in this case since your device it programmed to shut down with good marginal of battery depletion. What you SHOULD NOT do is leave an empty battery uncharged for a long period of time.

Lithium batteries will be damaged if they are stored fully charged or fully discharged for extended periods of time. Thats why the battery is about half charged when its new. They have no memory effect, they just loose capacity.

Good point. While it's important not to fully discharge the battery too often, there is also the issue of calibrating the battery meter.

The whole "discharging the battery fully" thing doesn't really apply here - because nobody will ever fully discharge it. The Nexus uses a Lithium Ion cell - it's a single cell, with a nominal voltage of 3.6V. When fully charged, it peaks at 4.2V (at which point, the charging circuitry cuts off to avoid overcharging). However, when we "fully discharge" our phones, the cell only goes as low as 3.5V - and then the phone shuts off.
In reality, lithium cells can discharge to around 3.0V before any damage occurs. However, this would yield very little extra battery life. Stopping at 3.5V provides a wide safety margin (lithium cells are potentially dangerous if overcharged/discharged), whilst extending cell life.
In a nutshell - don't worry about running your phone down to 0% (unless you're putting it in storage, in which case leave it at about 60%). In fact, it's a good thing with a new phone, as cycling (charging and discharging a cell) helps to "wake" the cell up and reach it's max capacity more quickly.

i see some good ideas about charging and discharging.
but it is indeed a fact that 100% and 0%(real) isnt good for our new race of battery's.
but a few posts here already tell how and what.
and its not gonna be a thread of arguments and stuff,if we all keep it in our heads that we just want to share our tip's of how you think its the best way(and have some experience with it)
just to share some info. and not compete the info against each other.
i well know there are different ways. but its always nice to read what experience people have with it to make a choice for my own and any other wanting to know this.
and i posted here in the GN section,instead of the Android section because each phone handles battery different,and this narrows the options down to a single device :3

Just keep in mind it's not just about the battery itself it's about the software registering how much actual power the battery has at a certain time, so if the battery has in actuality 100% charge in it, and the software reads 80 then your phone will die out sooner. So charging and discharging is good because it calibrates the hardware with the software. Just remember to switch off the device then charge it so the software doesn't auto discharge when it thinks the battery reached 100%.

K i just skipped thru the posts, gonna throw in my input real quick.
Basically just run down the battery. Once it turns off, hold the power button to make sure all the juice is gone. Then charge it up to 100% and leave it there for a good hour. Now (root required) download https://market.android.com/details?...yLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd and follow the instructions .. its not exactly necessary but a nice thing "just in case" .
thats my plan anyways.

Lithium batteries will be damaged if they are stored fully charged or fully discharged for extended periods of time. Thats why the battery is about half charged when its new. They have no memory effect, they just loose capacity.

Where does the loosed capacity go? Can it be caught?

And what do you think about charging with the phone being switched on? Is it better to have it switched off?

Won't make a difference.. Phones are designed to be left on anyway.

[Q] Confusion regarding the battery cycles

I recently bought a note 3 and I wanted to ask is it okay if I put it into overnight charge even if the battery is 60-70% ?
Does putting it on a charger over long period of times affect the battery life?

battery has protective circuit that will cut off the current when fully charged, since Li-ion batts are very sensitive to overcharging and discharging bellow spec and will get damaged quickly if done so. However, since there is always some possibility of malfunction I would not leave the batt. at home on the charger and left for 2 weeks vacation, but overnight should be fine, probably many people do so.

Thank you Pete for such an elaborate reply. In your opinion would it affect the battery if I put the phone over night every night for, let's say, 3-4 months?

I charge nightly so that when I wake up the phone is fully charged. Seriously, if the battery starts to wear out you can simply replace it. It is removable. Not a big deal.

I leave it charging every night

Buy an extra battery and swap out when it gets down to 15%. Saves wear and tear on the charging port and keeps away extraneous heat from having the phone itself charging the battery.

Imho even if you would charge overnight you wont notice any difference untill your phone is EOL. Even if you would treat your liion battery like a princess it would still die in ~5 years (please correct me if im wrong).
Even though this is only my personal experience and your mileage may differ, but im currently using a HTC HD2 which is still going strong on its first battery. I plug it in almost every night before i go to bed.
Edit: and I must add that really your phone is designed to be used like this. If you only have 70% left and you really need that extra juice the next (few) day(s) because you wont have a charger with you, just plug it in as you go to bed.
If you really go out of your way to rape your battery every day, just buy a new one when its EOL, if you haven't gotten a new device already.
