The Best To Charge Battery?

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%.

This thread here might be a good reference for this topic.

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. :/

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.

Replacement Battery?

Flattened my Xoom earlier, as I do everynow and again to full cycle the battery.
Came back to it a bit later and it had charged up to 40 odd %
Used it for a while then it suddenly said the battery was flat and switched off..
Anyone else had this, am I looking at a dead battery or should I just leave it swtiched off and on charge overnight?

It shouldn't be, lithium ion batteries don't have as intense a memory problem as the old nicad batteries...maybe just wipe the batteries stats in clockwork for good measure and take it from there. Sorry I forgot to mention that this would assume you are rooted. All my Android devices have weird jumps like that, but not usually that extreme.

cool, I'll clear the battery stats and see what it says in the morning.

Clear the stats in the morning after the full night charge not before..

Good job I checked here before I went to sleep eh

Lithium batteries do not like to go all the way down to dead (so low the device won't even start). They wear alot if you do. There is no reason to cykle them after the first time charge as there is no memory effect on them.
I had a laptop battery partially charged installed in my laptop and did't use it for two weeks. The battery went compleatly dead and when I charged it I only got like 20% into it before it said full. I had to buy a new battery.
So don't leave your XOOM with 1% battery for a long time. If you are not gonna use it for a prolonged time charge it up to about 75% before leaving it.

SEALen is correct, Lithium batteries should not be fully discharged it significantly shortens their lifespan, there is also no memory effect, the only battery type that ever did have one is NiCad.
The best way to keep a lithium battery healthy is to charge little and often, keep it topped up.

+ 1 to your arguments however if he is doing a calibration, i let it get to 1% before charging it again, i dont let it die i watch battery widget pro and watch the mA.. This will not fix a battery but give better indication of its lifespan

Battery charge from 80% to 100%=(

Hi, sry for my english=(
When i charge my battery its normally charge to 80% and then becomes 100%.
Try calibrate battery but this doesnt help. Also try another roms and kernels.
Is it a battery issue?

U can buy new battery from DEALEXTREME.com

so its the only way?

Try this.
Charge battery to full. Leave plugged in, Turn off fastboot in power settings and shut phone off. Light will turn orange again and let it charge til green. Boot into recovery and wipe battery stats. After this let the battery drain as low as 10% before recharging to full without unplugging. Do this a few times over a few days. If you don't get more accurate percentages after this then the battery could be messed up.

thx i will try.

i have the exact same issue. i have done battery stat wipe..flashed multiple roms over and over with full wipe and all that. battery charges up to 80% then the LED turns green..and stays that way till it reaches 100%. it jumps from 80% to 100% in just a few minutes.

battery jump
I wouldn't worry Lendlord mine does the same (see attached pic) you can see the green line jumps up from 80 to 100 but doesn't jump down from 100 to 80 under use. The picture is taken from Battery monitor widget, it's a great app which shows mv, ma, % and temp and even keeps a text log of what ma drain there has been allowing you to monitor battery drain while you're using your phone or while it is sleeping.
Here's a great guide aswell of how to ensure best battery life by memnoc:

And one more request.
Can someone post your current widget log?

I have the same thing happen to mine, i think its because you've let your DHD die due to low battery levels and that damages the battery which i think causes this problem

..letting the phone shut off because of a completely discharged battery is NOT good for the lifetime of Li-ION batteries.
The battery could be hurt and the amount of mAh the battery is able to store might be lower after.
Also trying to 'pump' the battery to fully charge by connecting / disconnecting while the phone is down is not a good advice because li-ion batteries also don't like overcharging.
To be sure that the battery is fully charged due to its ability it is sufficient to let the phone be conectet to charger or usb overnight.
Android uses the voltage of the battery to estimate (!) the % charge value.
Android supposes the battery is fully charged when it enters the voltage of about 4.2 Volt which is the charging cut-off voltage for li-ion cells.
Now when charging again the conceded voltage is reached more quickly than estimated by android, so the system is 'surprised' of this rapid charge and changes the % value to 100% because the conceded voltage is reached more quicklyy as supposed.
(Try to fill a 0.5ltr beer bottle into a 0.33 glass)
This is the normal of aging for li-ion batteries.
Consider for yourself if it's acceptable for you or if you should by a new battery.
by the way... be careful with cheap china batteries for 10$.
Offers with exaggerated values (up to 1600mAh) will mostly keep their promises
only for the first two or three charges only and will than fall back to 800 mAh or even less !
Greetz
Pudel

Yeah...
My battery started to do the same thing for a week or two. It will charge to 86% then it jumps to 100%, saying it's charged.

This is normal afaik, nothing to worry about.

actually，it's the problem of your rom , in the framwork.apk . unzip it you will get a lot of battery icon form 1%to 100% in the res file ，if it made mistake，that 'your problem. you can go to uot kitchen to coustom it again.

Nope!
I've solved my problem. I've bought a new (original) htc battery, and the new one works great. I haven't reflashed the rom, or made any new modification. Just added the new battery.
So, yes, it's a faulty battery.

I think you'll fine but it will take longer time to charge as the Note charger has higher amp

Charging slower is fine, just don't want it to stuff up / shorten the battery life.
Just that I've being feeling that my battery seems shorter standby/use time now..
Maybe becoz started using google now?
Also is there any ways to maintain the battery life? Does discharging still work?

Hey
To my knowledge its best to charge these new batteries often... it was in the old days that it was best to let the batteries discharge completely, before recharging... I've heard that this might even harm the new generation of batteries...
- Bobo

Yes I came across the same info when I was using my HTC one x --> charge as often.
So same for our SGN2
= charge often, no need to discharge method.
Now can anyone confirming that google now drains power more than expected?
Somehow I was getting more than 1 day of life before but now with same usage my battery can bearly make it to the next morning?

If you want a fast charge, find yourself a Nexus 7 or Kindle Fire HD charger.

So these chargers will charge faster and not harm our note2 battery?
Any perticular voltage or watts to look for on these chargers?

Thank you, the battery life depends on repeatedly charging and discharging frequency, so should try to avoid more charge when the battery power, this will shorten the service life of the battery. Mobile phone off time more than 7 days, should first will phone the battery to completely discharge, enough electricity before use

No that's just wrong!
Phone off, leave the battery atleat 50% charged.
Do not completely discharge the battery if you can charge before it's 0%
It was true for NIMH batteries, but it's a long time since we had those kinds of battery, and ofcourse NiCd batteries.

yep, what rvenes mention should be the go = no need to discharge (drain battery to 0 and full charge).
simply charge as often as possible, not letting it fall below 50%.
