{HELP}New Battery Question. - General Questions and Answers

i've just bought a 2000Mah battery for my Diamond.
all i need to do is fully charge/discharge battery up to 4 cycles before achieving full capacity of a new battery right?
what i want to ask is. can i turn on my phone while charging my battery?
of course i can!
but, i want my battery is in maximum capacity and longer life time.
how to do that? should i turn off the phone while i'm charging it for the first time?
thanks for answering.
cheers!, nightly_shadow

In theory, it would be best if you left the phone to fully charge without touching it, then let it fully discharge by heavy usage.

oh.. ok. i got it. thanks for your opinion.

[Q] just got my new g2x how should i charge the battery?

my last g2x battery lasted like 4 hrs on a full charge what is the best way to charge the new one? do i let the battery run out then charge it?
When you first get a phone, you should let the battery die before charing it. Then charge it completely after it dies, this will maximize your battery life. If you charge it right out the box, you're actually reducing the amount of juice the battery can hold.

That's not really accurate. Lithium Ion batteries have no memory effect like older batteries so charging them from halfway full does not reduce the maximum capacity.
What happens is the phone needs to learn to measure the amount of mAh from the phone and recognize what battery % that means. By taking the phone through the full discharging and charging cycle, the battery drivers pick up on this and will better report the battery level. With a poorly calibrated battery, you do not get less battery, but instead you just will not see accurate information about the charge level. For example, my first discharge went quickly to about 10%, and even quickly below 5%, but stayed on for hours between 5% to eventually shutting off.
The battery still will not die faster, but my phone thought it was much lower than it was, giving it the appearance of dying faster. Point is, you can do the charge/discharge cycle whenever, not just the first time, and it won't effect your long term battery health.
1) do factory reset
2) drain completely
3) charge completely
thanks!
thanks everyone for your advice!
I think it really depends on who you ask. lol Some people will say let it drain first then charge it fully. I have read info on battery maker sites that suggest when you get their battery that you let it charge fully for at least 8 hours, then let it discharge fully. They say to do this the first 5 charges to increase battery life.
When I get a new phone or battery that's what I do. as soon as I get it I charge it up overnight, then let it discharge completely for the first 5 charges. I can only speak by my experience and my experience tells me it makes a difference. Here is my reasoning: me and my ex gf went one day to get new phones. We got the same phone. She started using hers as soon as we left the store. I waited. I charged it up overnight fully and did the conditioning procedure. Our phones were pretty much mirrors of each other app and software wise. Her battery would die out a couple of hours before mine. Battery usage also didnt report any HUGE differences in consumption .
Also every once and a while I go into Clockwork recovery and wipe battery stats(after it's been fully discharged) and re do the conditioning process. It might just be a mental thing, but for me this seems to work
supposedly from htc.....
1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well
I heard/read somewhere that you should never let a lithium ion battery fully discharge. It supposedly shortens its lifespan every time you fully discharge it. Instead, you are suppose to just top it off and not let it remain on the charger, for extended periods of time, once its reached a full charge. YMMV

This is "more" true for everyday normal usage. Yes, you shouldn't constantly fully charge and fully discharge every time you use your phone. But for battery calibration it is necessary/beneficial.
I also hard that during the first charge after turning the phone off you have to strange on your head for ten minutes, then only use your left hand for the rest of the day and you will double your battery life

[Q] Am I Damaging My Battery?

I go out at night mostly so by the time i leave the house my phones battery is about 75% full. I have the LG G2x. My question is sometimes before i leave i'll see that it's 75% full so i'll charge it back to 100% before i leave. Does charging the phone without it being drained damage the battery? should i just leave it alone next time i go out? sorry if this is already a thread just point me in the right direction.
Thanks.
You're not damaging your battery But if you never drain the battery completely, i'm not sure how good the battery will be after 6 month, so i recommend you drain it completely every couple of weeks.

There are several opinions about keeping battery health for more time. Recharging at 75% is not one of them, but it's not the worth of it.
Here's what i know and what i've heard:
* some manufacturers (laptops) have software that don't allow the battery to charge when it's over 80 to 90% - they say it helps on battery life
* it's common sense that you should recharge when you have 20 - 40% and do a full cycle once in a while (this is what i do)
In my opinion, charging only 25% of the charge in a regular basis will not really help to keep battery life...
I've personally had the best performance from batteries when I let them discharge as much as possible and then charge them to full without interruption.
some have also said that draining the battery too often can also damage it, is this correct?
They like to be ran down then recharged but not all the way down to nothing unless you are having a problem with bat life on a rom

Yes. You should not drain your battery all the time. Use normally, charge it when below 40% and yes, charge it back to full - that's the ideal thing.

+1 that is the best way. Li-on batteries should'n be drained completly because it can shorten their life.
I read somewhere that it is not important when you start charging your battery (20%, 60%...) but it's important that it finishes to charge up to 100% every time
I heard/read that LI-ION batter is good to charge when cap goes bellow 30%.

[Q] leaving the Transformer connected to the charger good or bad?

Hello everyone
I was wondering if its ok to leave the transformer connected to the charger.
Is it like the Evo with trickle down when it reaches 100%
I dont want to over charge it. If it were my laptop i would disconnect the battery at full charge. But its not possible to do that with the transformer.
I want to keep my cycle count low and prevent over charing.
I also wonder what happens in a few years when the battery is shot...
Charging is what damages Li-Ion batteries... I'd recommend not keeping it on the charger all the time. Android will purposely not keep the battery at 100% to help avoid some damage.
Li-ion prefer to be around 20-80% charge.
When battery is 100% and you keep the charger connected, heat will begin to build up and eventually you will kill your battery.
I'd do as with a notebook: charge till 100%, then remove battery or charger (in case of the tablet charger ) . Then use your tablet and recharge when needed / desired. And from time to time a full charge / discharge cycle won't do any harm.
Just my 2 cents.
Regards.
These tablets don't automatically recognize when it's fully charged and turn off the charging?

They do. There are other threads asking why thier TF's don't show 100% when unplgged from the charger. Same as it does on my Evo.
I think pretty much every modern device recognizes a full charge and responds accordingly. In fact, MacBooks will throttle performance if the battery ISN'T kept in while the system is running on A/C.
Heat will damage a battery, but it's not heat from charging but heat from operation. If a notebook is poorly designed and the battery is near a heat source, then removing the battery might be a good idea (except with the aforementioned MacBooks), but that's independent of the charging issue.
I think it's fine to keep it plugged in. These devices are smart enough to manage such things. Of course, the TF's charging cable's so short it's hard to use when plugged in, but that's a different issue entirely.

From what I understand this process cannot and will not kill the battery. This did happen in the old type of batteries with the ,emory effect but these new batteries and the OS's management system for charging does not allow the battery to be killed.
it will heat up and that would happen as there is a flow of electricity but not to a level that would kill the battery.

IS it normal to go from 4% battery to 99% in under 3 hours ?
I thought this was supposed to take 8 hours to charge.

Yes that's normal. It's meant to take about 3hrs.
Thanks guys...
Still dont know about it. Because I think its like my EVO and technology got so good that my battery is protected.
I really dont want my transformer to become a expensive paper weight or non-mobile because after a few years it has 45 mins battery life.
I've got the first full charge and full depletion done. Is it ok to use while charging now as long as I fully charge and fully deplete it a couple more times?

batteries will degrade over time....would you be keeping this tablet for over 2-3 years? a simple battery change could work if ever needed
I am no expert, but I have spent some time searching around the internet looking for information on the best methods for improving the life of a battery. Most of the information I have found said it is bad to completely discharge a Li-polymer battery. The articarles stated it was best to charge the battery when it reaches 20% to avoid shortening its life.

Batteries are like muscles - they like to be exercised.
Leaving the unit plugged in WILL NOT HURT YOUR BATTERY. Period. The charging circuitry in modern devices is smart enough to cut current to the battery once it has reached a certain level of resistance.
Batteries do not like being deeply discharged. Most devices will shut off before the battery gets too deeply discharged, but it's never a good idea to tempt fate by running it until the device shuts off.
What really determines a battery's life is the number of cycles it has been put through. A cycle would be a full charge followed by a full (or to a lower end threshold) discharge.
The old original Lithium Ion batteries used in laptops would usually last about 300 full cycles or so - about a year if you used it on the battery every day. Partial discharges of course only count as fractions of a cycle.
Given the life of these types of devices, considering we'll likely upgrade to the next big thing in a year or so, I don't think anyone here will come close to 'wearing out' a battery.

As stated, these are Li-Ion batteries, and they do not need to be trained. The only reason you might need to do any training is to calibrate Android's understanding of the battery (although I doubt you need to do a full discharge for that, either).
It's not going to suddenly kill it, but it will over time hurt your battery's life.
I went ahead and did a full discharge/charge cycle, but only because Asus said to do so in the manual. Maybe the copywriter just copied/pasted from a circa 1990's manual for a device with a NiCd battery, but I figured if they're suggesting it, I might as well do it.

battery question

hi, is that tru, that is better to charge your device the first 3 times 12 hours? because i know that with the new batteries don´t need that like some smartphones?
and i hear that is better if i discharge totally the battery and then i charge until 100% so if that is true, that means that is not good to charge like 1 hour?
thank you.
It is actually bad for the battery (Lithium-ion or Lithium-polymer) to discharge it completely. You should always aim to grab the charger at around 20%, refill to 100%, then remove the charger.
Newer batteries don't worry so much about 'trickle charging' once the battery is full (and newer, more energy-conscious chargers may actually switch themselves off internally to prevent wastage and damage to the cell).
If you have a brand new phone, the first charge should be for 12-18 hours, preferably without use (if you can bear it). You won't see the maximum battery life from the cell until you 'cycle' (charge/discharge) it a few times, but after a week or so you should get a profound increase in battery life.
Just remember - no lower than 20%
Hope this helps!

NO! This is bullsh*t that u need to load battery 12 hrs, better take ur battery off and throw in sh*ting bowl and w8 sb to go toilet or you can urinate too and see, what happen! u can try it high voltage battery too, i hope that result is same..

for first time it is good for the battery so that it gain its max capacity..so when you get the phone first charge it to 10 hrs.and dont use at that time and also charge your battery only when it goes below 5% because every phone is having its charge and discharge life...
I usually have my charger connected to my phone, is that a bad idea then?
No special reasons to do it but if must go out suddenly and i don't have enough battery...
Yes it is....your battery ruins day by day..just charge when the battery level is below 5%'...
Xperian8~ click thanks if it helps...
Thanked! My old cell phone could still power on without a battery using the charger, that's one of the functions which i miss on this smart phones.

Over charge battery?

Hi.
I charge my phone overnight. 8 hours. Will that degrade the battery? Or does the phone prevent over charging?
Thanks in advance.
I wouldn't worry about it
No, if you leave it on 16 hours you'll get 200% battery level. Brilliant

The phone prevents overcharging, however it is still not good for the battery to
a) always charge it to 100%
b) keep it at 100% for 8hours
The general advice is to keep the battery between 20 - 80%. Granted, most people need a full charge to start the day and some people don't hold on to their phones for long.
Fast charging degenerates the battery faster, a fact oems omit to point out in their quest for faster charging speeds.
If you're not in a rush, you should just use a normal charger.
No damage done
And any long term effects will not be noticeable
By the time you notice any battery degeneration from keeping it at 100% you'd probably be on another phone.
hi are you rooted? if so I suggest you use an app called Battery Charge Limit. You can set when your device stops charging (preferably at 80%) and when it starts charging back up again. Again, you need root.
Since launch, most of the time I do 20-80%. So far so good
