Hi All, I have question. Which one better to charge
1. Wait until Battery level reach 15% or less
2. Charge it every we want it, example battery status in 40% because we want to travelling, we charge it until 100%
3. Charge it every morning
4. Other Tips?
Best Regards

Hello
You should just plug it in when ever you have the chance m8.
Li-ion and lipo batteries does not suffer from the memory effect as nicd and nimh batteries did.
The li-ion and lipo batteries will most likely die if you do a full discharge, but no worries, when your phone tells you that it's out of power, it's not fully discharged.
Your phone has at built in protection, that shuts down the phone before it uses all the power on the battery.
(Have been working with batterie for many years, as I have been flying eletric model airplanes, with all types of batteries)
There are a huge number of threads on this!

Thanks you for this tips... now I have more knowledge about battery.
A little bit question again.
What should I do, when I charge my HTC Desire? Keep this gadget turn on or turn off this gadget and turn on again when the charging has completed?

Just keep it turned on m8.
leaving it on has a disadvantage
as soon as battery is full, it discharges. at a certain point it would charge again.
you lose unneccessary charging cycles for your battery. so charge over night with turned off handset.
Not true really. The life of Li-ion batteries is mainly rated in full charge/discharge cycles between what the manufacturer recommends as the limits. Fox max life this is often a maximum of 80%SOC and min of 20%. They ship them about 40% SOC as this is where they have longest shelf life. The phone manages these limits for you so you don't need to worry. The best thing to do is to keep it topped up but let it run down enough during the day, or it reduces battery life (think laptop that gets left plugged in Vs one that gets discharged a bit per day - leaving it plugged in kills the battery).
IMHO - Use it until your next at a charger be that at 70% or 7%.

1. I always try to charge it 10-15%
2. Sometimes i do charge it if the battery is 40% and im worried it might not last because i go somwhere, so charge it till full and unplug
3. Most of the time i charge it over night having the phone on.
Right now, end of day 2 and battery level is at 29%, probably due to 3g turned off as got connection failed error for couple days and cant connect :<
Put my new second battery to charge last night around 9pm - turned Desire off. The green light came after midnight, but I let the charger stay on. I disconnected the cable around 9am this morning - and the phone was on!!
It looks the phone turns on automatically when its fully charged(???!!!)
The charge was 94% with the green light on. Makes me doubt if the suggested (see other threads) initial charge needs to be 12hours. :/
Hi,
I've just purchased a couple of cheap batteries off ebay and just wondered what was the best way of using them and charging them?
I've just recently calibrated the battery on the Z the other day (and now been getting upto 22 hours on a single charge! Yay!) and wondered do I need to do the same for the batteries I just bought as they come with their own charger.
I just want to get the best out of the phone and batteries so wanted to know what's the best thing to do.
Thanks in advance,
Jason
I would run them flat (keep phone on until it dies, turn it back on, let it die, turn it on, let it die, turn it on...... until it boots no more) before charging fully/overnight.
Batteries aren't calibrated, the battery meter on the phone is calibrated (basically, so the volt meter on the phone knows what voltages correspond to "full" battery and "empty"). Li ion batteries don't need to be conditioned like the old NiCad type. Really, you don't need to do anything. Li ion batteries should be stored with about 40% charge according to the link below. They should have shipped with some charge, and hold the charge pretty well. Just check them once in a while if stored for a long time.

No! Do not run the batteries until empty. Running a Li ion battery empty can possibly cause it to no longer take a charge. Try not to discharge below 20%. See the link below. The proper way to calibrate the battery meter is charge to full, drain to about 20%, repeat a couple times.
http://batteryuniversity.com/learn/article/do_and_dont_battery_table
And as I've already mentioned in my previous reply, charge/drain cycles on the battery does nothing does nothing to the battery itself. Li ion batteries don't need to be (and can't be) conditioned. Charge/drain cycles only calibrate the battery meter on the phone (possibly incorrectly, if you are just going to then store that battery). So you are just wasting your time.
Also, you shouldn't store the batteries fully charged.

Really?....
Links added to 'to do' list for later. Thank you pal. I really should research before taking peoples word as gospel.
Nice one.
What I've done is counter to what people always say about Lithium Ion batteries but I've had good success so I figured I'd share.
I have two batteries, one always lives in the phone and the other lives in an external charger (these can be had for as little as $5 on eBay).
Every morning I look at the phone and if the charge is <50% I pop the other battery off the charger and put it in my pocket. When the phones battery dies (may not be that day) I just swap the battery and when I get home I put the dead one on the external charger.
Periodically if I'm not in a hurry, I will even go so far as to power the phone on in recovery mode after the battery has died, it will run for a bit longer in recovery (sometimes as long as an hour) sucking a little bit more juice out of it.
I routinely get more than 2 days out of a battery charge.
I don't doubt that my method reduces the overall lifespan of my batteries but charge time is more important to me than battery lifetime and I end up picking up a new battery every 6 months ago and taking my oldest one out of service.

No problem. I used to think the same, about draining the battery until the phone died, then charging to full, to calibrate the battery meter. Until Jackos over in the Rhodium forum informed me otherwise. I've also read pretty occasional posts over there (and likely other phones) by various users that discharged their battery too low, and then couldn't start their phones or charge the battery. Every phone is different, and I think a user on here said the Vision has better safety measures to prevent this. But best to play it safe. There is really no benefit to intentionally draining your battery to 0% versus 20%. Your battery meter will still be plenty accurate enough.
Ah ok thanks guys a lot of useful info here.
So to sum up:
- I can charge the batteries normally on the phone without need for calibrating either phone or battery.
And one more question:
- Are there adverse affects from charging the official battery or ebay batteries on the external charger?
Loving the Desire Z at the moment, I think I'll have one spare battery on me when at work or commuting on public transport and one in the car.
Thanks again!

They both charge fine either on the external charger or in the phone but in general I've had better performance with OEM batteries than with the generics, I suspect that there is a wide range or quality among generic batteries where the OEMs are more consistent.
Right now I have one OEM and one Generic, despite the Generic having a higher MAh rating and being newer in general I get more time on a charge off the OEM battery.
You can check eBay for a good deal on OEM batteries, just be sure to read the item description carefully to make sure you are getting a real OEM battery as opposed to an "OEM-type".

If you are going to be swapping batteries frequently, then I would say that there is no point in calibrating the battery meter on the phone. Its never going to be completely correct if you keep swapping the battery. If you are going to use one battery for a long time, I'd say calibrate the battery meter. There is no such thing as calibrating the battery, so obviously no on that.

I'm not sure on this, so maybe others have a better answer. But I'd say as long as the voltage is the same, it wouldn't matter if you used the phone or an external charger to charge the batteries.
From what I've read, Li ion batteries have safety circuitry to prevent over-charge, so you don't need to worry about the charger having that.
So I just got this battery hm around Wednesday or Thursday, and I have let it die down to around 10% or less and recharged it overnight several times and I still only see a slight difference in battery life. I am (I would say) a moderate user and I know some people say they get around 2 days on heavy use so I wonder what I'm doing wrong..? I ran the SU command to delete the battery.bin file to wipe the stats while it was fully charged, then let it run the whole day again only getting around 12 hrs (probably would have been shorter, but I have juicedefender running, and I was at work for 5 1/2 hrs of those 12) and then I stuck it on the charger at about 7:45 and then around 12 it was fully charged and I of course turned it off, then back on and it said it was around 80% so I let it charged to full, reset it again then when I turned it back on it said it was full. I took it off the charger and within minutes it dropped 1% every minute or 2 and now around 15 minutes later it's at 86% and I'm not even doing anything, just sitting here with the screen on and Skype is running. I've only drained it/fully charged it a few times maybe 3 or 4 should I just keep doing that or did I just get a crappy battery? It's better life than the stock, so I can't help but think that it's not crappy just not fully calibrated or "worn in" yet. Any help would be greatly appreciated!
I too have a cheapo extended battery from eBay, for the first week I hated it, but finally I actually just let the thing completely die to wear the phone shut down and wouldn't turn back on, then I recharged the battery completely in a standalone charger(also ebay), then put it back in the phone and used normally, charging and discharging and now I can't even dream of going back to the OEM battery, my battery life has much more than doubled. I use my phone like most here with CM7 up to date on nightlys and I'm happy as can be. I also like the ext back on the cheapos much better than the seidio flavor.
So you use the wall charger from eBay to charge it? I don't want to take my battery out to charge it though every night, let alone turn it off because I use it as an alarm clock :X. I've read a whole bunch of different ways of how to charge it in your phone and most people even one of the legitimate companies (Seido) who sells it, says that if you let it go an hr or 2 after the light turns green its good to go, but I don't believe it charges after the light turns green hence why the charging icon on the battery goes away. people may "think" it does but I honestly don't think it does and if anybody can prove otherwise I might have to buy the external charger :/
Yes get an external charger, Preferably 2 batteries and 1 external charger.
I just ordered a wall charger for like $15 I hope this works. I'll just charge my extended battery at night and use my other battery when the extended is charging

I used the external charger just once to "calibrate" the battery it seemed? Since then I've not taken the battery from the phone and just charged it with the phone charger(plugging it in) and I have noticed a huge change in run time.
How do you charge it though now that its calibrated? Do you just leave it on the charger for a few hrs after it hits green or do you have to turn the phone off and back on then stick it on the charger

Well my cheap battery has not blown up with sbc kernels
Yeah, its been about a week and my battery still can't even hold a charge, even if it isn't fully charging. It dies quicker than my stock battery. I told the guy I bought it from, and he said he'd send me a new one so I'm back to the stock battery for now until I get this one next week :/
Hey guys, i know it's a tiny bit off topic, but what about a battery pack??

i have two of those things and they work perfectly. plus, i don't have to kill the phone, open her up and swap batteries. additionally, it'll charge two devices at a time. bonus!
Hmm see that's what I'm trying to get rid of lol having to plug it in all the time. Plus I actually like the bigger back, I personally don't like the thin size of the evo I feel like I could drop it at any time.

How are you guys getting so many hours? I only get like 8 Hours on my heavy use and i bought a 3500mah extended battery wtf? I'm also using the net Netarchy sbc 3.2 more havs and mym rom with setcpu running profiles. What am I doing wrong? I even have juice defender running aswell.
I had my 3500 extended battery and at first it wasnt too good. But after switching to an external charger for all charges and completely letting the battery die out im getting a whole days worth of heavy use with no worries.
No rooting or any battery controls.

Just got the Note 2, and want to make sure that I treat it really well. I've long been uncertain on the best way to treat batteries. Am I supposed to drain it as closer to 0% and then charge it back to 100%, or is it fine to charge it whenever, even if I'm only down to 62% or something at the end of the day? Seeing as how it's brand new, is there anything I should be doing in the immediate future to properly condition the Note 2's battery? Thanks
You can fully charge the battery drops below 20%.
You can do whatever you want. New batteries technology much better than before

I charge mine every night regardless of percentage (usually around 15% but i sometimes charge over night even at 60%). My battery is still as good as the day i got it.
No need to drain and charge.
Some people say that it reduces the number of cycles of charges the battery can have but it wont make any noticable impact for about 2 years anyway when you're likely to get a new phone anyway, otherwise the cost of a replacement battery is well worth the convenience of charging however you like lol
Sent from my GT-N7100 using xda premium
with lithium ion batteries, you get more overall charges if you charge it before the battery dies.
ie. 100% drain gives you 500 charges
50% drain gives you 1300 charges.
25% drain gives you 2000 charges.
or something like that. also with lithium ion batteries, its bad to completely drain it. when a lithium ion battery is completely drained, it reduces the overall capacity of the battery. most phones have safeguards in place to prevent a complete drain, but leaving a dead battery out for too long without recharging isnt good.
plus, lithium ion batteries dont have the 'memory effect' so draining them fully is pointless. NiCd and NiMH batteries are the ones that lose voltage if not completely discharged regularly.
Dude ... the battery management technology is good in theory. . To understand. ... but in practical use. ..go ahead and charge it as you like. ..the battery will last good for 2-3 yrs... then you can replace the battery. ..note 2 has a replaceable cheap battery unlike the other new devices that are coming out with no option to replace them
Just enjoy :beer:
scribbled from my note 2 (N7100)
You should charge the lithium battery whenever u can, charging more doesnt hurt it really but draining it to 0% is going to hurt it

Since it's Li-ion battery, it's recommended to partially charge whenever you can to preserve the battery longevity and fully charge it from 0% maybe once a month.
hi,
Does draining your battery life until its off before charging a good way?
I remember when I bought this phone the sales rep told me to never ever drain the batt and make sure to charge it when 20% or less.

Maybe once a month. But remember, it;s good to always charge your phone, even if you charge it half an hour, one hour, or fully charged. This way you keep the battery alive.
From what i read, you should usually avoid draining it full or charging it full. But once in a while do so for some calibration purpose.
thanks!
Hi!
The best way ( if you can ) is to power-off your device and than connect to the charger ! - assuming you have less of 10% .
Also is recommended for a battery long life, fully discharge the battery every two or three months !
On the other hand it is not wrong to charge the phone when you think , no matter how the battery indicator shows ! - this type of battery should not be formatted on beginning, cause is not a Ni-Mh or Ni-Cd type !

20%-80% is best fir li-ion/ li+-pol batterys. But I dont do that coz as it is the battrry does not last. I rather charge to 100% and replace battery along the line.
b.t.w. if the battery shows 0%, the battery is far from dead. just the internal circuit cutting the power off
thank you guys!
