and I don't remember where, but I read somewhere, some time ago, that when you get a new battery, you should fully charge, and fully discharge the battery a few times.. Is this a good idea? does it help the battery?
are there any tips, like doing a complete cycle every so often?
Also, well, I got this on Amazon so I'm hoping it really is brand new. The brand new batteries are supposed to be dead, not charged, right?
Lithium ion batteries are never shipped "dead", bad things can happen (read up on it). So when you buy a lithium ion battery it always has a charge on it. They also don't have a "memory" like older batteries do so just use it normally. When i got my Naztech battery it was fully charged!
Ouch.. So does that mean my battery isn't going to be as good as an OEM battery? It looks like it's a legit samsung battery, it has the same model #
Anyway I charged it up fully, then I had to send in my phone to Samsung, so I took it out. When it gets back I'll see how my battery life is.
Li-ion batteries aren't supposed to have a memory, however I read a lot of good articles that argue no batteries have memory. However that being said, I've had the best luck out of cycling batteries like that. We have 7 Samsung batteries for our Fascinates, and always just run them down and swap to the next battery. Whenever I get a new one I charge it up, then run it down a few times.
I always charge them, they do come partially charged, but usually not 100%.
Any battery "woes" of memory is all placebo affect much of the time. Unless the phone doesn't get a balanced charge it will have no memory. But I think these batteries are one cell so you don't have to worry about it.

If you have 7 batteries isn't it a pain swapping them back in to charge them?

you can get chargers, like just a wall charger that you can drop a battery or two in and it'll charge without the phone.

just had a thought, my g2x just started rebooting like crazy i.e it would get to the tmobile g2x android start up animation and after it finishes it would reboot. my battery was around 30%-35% at the time i was thinking maybe the battery cant maintain a decent voltage and it falls below the g2x voltage threshold while under load and boom instant reboot. this could also explain why some batteries heat up to hot as well, they dont have a high enough discharge rate to keep up with the demands of the phone.
this can be solved one of two ways get a larger capacity battery of the same discharge rate. or get a higher discharge rate battery of the same size. both of those will allow the phone to draw more power without overtaxing the battery and would keep the battery cooler as well.
I wouldn't be surprised if the battery drivers are the culprit for all our issues. The phone can't properly read the battery charge and so the battery overheats or the phone reboots itself in hopes of getting a better reading on the battery.
i noticed my phone starts to heat up when the battery level hits around 40%. i never really understood why.
Mine once rebooted when it was plugged in and 100% charged. I think when it's plugged in it draws power from charger not the battery. So your theory, if true, only explains some reboots, not all.

I may be mistaken, but if it was in fact 100% then it was probably drawing from the battery at that point. I believe that once they reach 100% they will cycle between battery usage and charging.
well i know from using lipo batterys in my r/c planes and cars that if you draw them below 3v it can damage the battey im not sure what Li-ion low voltage is but its near the same basicly once the battery hit around 3.6 volts at rest its empty and will not hold voltage at all.
and for the 100% full charge if the battery drivers is fubar it could be overcharging your battery and damaging it so it has less capacity so when it pulls a draw it cant keep up and reboots
I plug my phone in every day before going to bed, and unplug it in the morning. If G2x doesn't have overcharging protection my battery would have been damaged long ago.
Also, I used the phone several times when it was charged 100% and still plugged in, never saw battery percentage went to 99% then back to 100%. So I believe when 100% and plugged in, it won't cycle power source through battery and charger.

I will add a little information that may or may not have relevance. I have 4 batteries for my G2X (This is my solution to the short battery life). The LG battery, $25 AceSoft battery, and two $6 generic Chinese batteries. None of them including the dirt cheap ones cause my phone to reboot. Conclusions can be drawn from this information but I'm going to leave that up to someone else. If you want to test the battery hypothesis I suggest you buy some of those cheap batteries off of eBay and see if something changes. Would be a rather inexpensive experiment.
I agree, ever since I started using a 1900mah battery from ebay, the random reboots and freezing issues have disappeared completely, and I have been using the phone for almost a month now. Please try a different battery to get rid of random reboots and overheating issue. Hope it will help someone.

you know what, I bought 3 ebay batteries so I can swap them around if i don't have a charger. none of them did the black lock screen. weird.
I had random reboot issues using some of the custom roms + original battery.
Then I bought a charger + batteries off ebay, and reset to original rom, and havn't had a single reboot/freeze since.
i just had my second reboot in cyanogen with my battery at 32% after if rebooted it went back up to 45%. i was playing galaxy on fire 2 when it rebooted. and according to battery monitor it was pulling 931mA when it rebooted.
i think the battery discharge rate is substandard for this phone this is a high performance phone and you cant just stick a normal cell phone battery in and expect it to work. this is in part why some of the reboots are happening and why when people got new battery they problem went away for them.
You might be on to something. Everytime my phone restarts it is because it is overheating.

i wish we had more info on the batterys lg used like the discharge rate and everything. i bet they are .5c or 1c discharge that would be why they overcheat when under heavy use or charging
I got a replacement battery from T-Mobile this past Tuesday, and had two random reboots within an hour. However, since then, I haven't had one issue. 4 days and counting going strong... Knocking on wood. Phone is stock and rooted.
well i know cm fixed the battery should be in his next build also data speeds with gingerbread, should be build 54 not 53, something is wrong with 53 and root access so they are going to have it fixed im pretty sure in 54, here peep this via twitter.........
@CM_arcee RC
My dark magical powers have beaten the G2x's radio into submission. Starting tonight, p999 gets a battery meter and twice the data speed
3 hours ago via web
while that is awsome news i dont think the battery meter for the phone is really the problem it happens when the draw on the battery pulls it below 3v under load the batterys low voltage cutoff kicks in and shuts the phone off and then the spings back up and the phone restarts
I think it could be the chargers causing issues. My gf pulled my g2x charger out of the box and said it made her phone whacky and died after a few hours.
Her comment made me think about it.
I never had battery issues but I use my old nexus one and zune charger.

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

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

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.

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?

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.

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.

Every Android device i have ever owned says to unplug the charger when the battery is full.
But from what little i know about Li-ion batteries, it is best to keep them plugged in for as much as possible.
So what's best for the overall battery life?
http://forum.xda-developers.com/showthread.php?t=1168036
I believe most phones battery now are lithium polymer, or such, I forgot. They are actually the opposite, once full, let it drain. Lithium ion are different, I doubt people are still using them unless those aftermarket stuff. Once lithium ion drain, they can never reach full 100 percent again. That's why you want them to be charge most of the time. Why you think laptop battery never last long like the first time you use it.

When I first got my Galaxy S3 (Verizon) the OEM battery lasted at least a good 9 or 10 hours, usually plenty to last the day. But I wanted more than that so I got a pack of 2x QCell 2300mAh batteries for cheap on amazon, with one of the wall chargers that you pop the battery into. That was July of last year and I promptly lost one of the batts at school, so in May of this year I got another pack of 2 batts, this time EZOPower, 2100mAh.
Both brands worked pretty well while I had them and I would generally just start the day taking my GS3 off the charger and putting the extra battery in my pocket, and at ~8pm or so I'd switch them out and have more than enough for the rest of the day, and some for the next day if I didn't make it home for some reason that night.
But recently that time to switch has been creeping down earlier and earlier, and lately I've noticed I wake up to the battery icon showing the circle but no percentage (just switched from AOSP to Pacrom, dunno if that makes a difference) and when I take it off it's about 95%. When I switch batts, which is now at about 2 or 3pm if I wake up at 10, the second one (coming off the cheap battery-only wall charger) is at 75% or thereabouts and each lasts less than 5 hours.
Attached are my stats from the other day. I keep all my radios on all day usually but lately I've been having to selectively put it on airplane mode whenever I can afford to, if I want to have enough juice to last through the evening. This sucks. I know batteries die over time but I've literally had these ones for a few months and they're terrible already. Is it because of my hot swapping habits? Does that drive down the battery life over time, or is it something to do with how android pegs the amount of juice left on each battery? Is there a way to wipe the battery stats, or would that even help? There used to be an option for it in CWM but I looked today and I suppose it's gone. I'm not sure what I'm doing wrong but I've never had battery life this bad on any phone.
tl;dr bought a pair of non-OEM batteries with a wall charger, been hot-swapping them for more power throughout the day, but in just a few months their life is approaching nil. What am I doing wrong?
Bump. Anyone knowledgeable on this? I'm pretty sure it could apply to just about any phone and I know plenty of other people do the same thing I do with these battery pairs on Amazon so this would be useful for progeny.
Do you leave them in the charger until you need them? Usually, the longer a battery charges while it's fully charged, the more the total charge will diminish. So, the longer you keep it charging more than it needs to, the faster the battery dies out. Also, when you get a new rechargeable battery, or even a new phone or tablet with a rechargeable battery in it, the first thing you should do is use it till it's drained. Don't immediately plug it in to the charger. Keep in mind, though, that no matter what you do your batteries will diminish. Cheaply made batteries will diminish faster than higher quality ones, so that may attribute to how fast your batteries are dieing.
I could be wrong, though.
I actually do keep it on the charger long after it's charged. And I have heard that before - but don't most chargers have a built in feature that cuts off the current once the battery is fully charged?
Anyway I'm not sure that's the sole reason for the batteries being so ****ty. Although idk, I also could be wrong, lol.
