Hello everyone,
Getting my G2 tomorrow ad was wondering what's best to do for the initial charge ?
What did you all do and how do you find your battery because of it ?
Cheers James
hi there mate
I did a 3-4 hour charge until the battery was fully charged...the orange led charge thing goes green and its fine then
right now im managing to get a day with heavy use, which is good
Thanks immya
Any other advice please ?
I atcually do the same. But i repeat the process of fully charge and discharge the phone completly about 2-3 times. So the battery gets well trained. I repeat ist about every 2 months. I know it should not be relevant with those new batteries, but i found out it is, and the battery last longer.
jut my 2 cents
Cheers,

it's 2009, just charge it and use it.
when i got mine the battery was ~1/3 full, i charged it till ~2/3, then had to leave and completed the initial charge like two hours later, all works fine, getting somewhat between 4 hours and 3 days of usage.

Hey chaos42
What do you mean should not be relevent with the new batteries ?
Is there some sort of new batteries with the newer phones ?
Thanks
James
no, what i meant was what immya just said. that with the modern Li-Ion batteries you should not worry to much about how and when to charge. I just wanted to add that even it is 2009 i observed a far better battery lifecycle and stamina when you try to take care of your batterie. and charge it as decribed. that's my experience. at least for the initial 2-3 charges.
cheers,
chaos42
not that i am trying to discredit you here (in fact i would be very interested in such numbers myself), but did you do any tests or comparable setups to check the difference? because if we are talking about "a feeling" that you have this is IMHO not really relevant data. i would like to see two identical phones in a (at least) similar environment, performing the same tasks the same amount of time a day, and with that getting different runtimes on the battery for a period of a few weeks. these two phones don't need to be heros necessarily, as long as they have the same type of battery and can produce comparable results, but as long as this doesn't happen i myself rely on the tone on li-ion batterys in general. which is (and i am not able to quote or prove this): they are robust in terms of regular charging, and worrying about wearing the batterys in or training them isn't worth the effort. again no discredit here, but as long as no comparison has taken place there is effectively no data to analyze... just too much variables.

NiCad batteries work best when fully discharged before re-charging otherwise you get what is called the memory effect. If you are in the habit of topping up before being fully discharged the better 'remembers' how much you let it drain before charging it and then get's the idea somehow that this is what its capacity is and goes flat at the point that it 'expects' to be recharged.
NiMH batteries are much less prone to memory effect. They are the ones that need the 16 hour first charge then subsequent charges are shorter.
Li-Ion - lithium to its friends - are not supposed to suffer any memory effect at all. You are supposed to be able to top up as and when you want without any detrimental effects.
None of the above batteries will last forever and will need replacing after 2 or 3 years of daily use.

Absolutely spot on!
These days batteries do not require dishcharging fully before recharging. Even if the person in the phone shop says "ensure you charge it for 12-14 hours before you use it", this doesn't matter - once the battery is fully charged, it stops charging itself anyway - even if you leave it plugged into a charger!
Same as what's being said already.
To add, it's even better to keep your lithium battery topped. Fully discharging them is actually bad for a lithium battery. Full discharge and heat is what's bad for a lithium battery.
For a nice reference, check this: http://electronics.howstuffworks.com/lithium-ion-battery.htm
(the life and death part is what might interest you)
On a more interesting note. A long long time ago I got a MDA Compact aka Qtek s100. And there was a lot of debate here on the forums about the initial charge. In the manual it was stated that you should charge it for like 12 hours or something the first time. Then people obviously also said that was bull, because it had a lithium battery.
But! As for WM2003 it didn't save it's whole registry etc on the ROM but in the RAM. Once the battery was dead, bang! hard reset right there.
So they included a little NiMH battery in the s100 that would keep the RAM 'alive'. And that was the reason it needed such a long first charge, for the NiMH cell.
And for some reason a lot of manufacturers take an 'old' manual text for the first charge of a battery. Although that doesn't happen that often anymore. Especially in the beginning a lot of instructions of how to use a lithium battery were just plain wrong. And they put NiMH or even NiCad instruction in there!
Edit, some instructions as found here (http://www.batteryuniversity.com/parttwo-34.htm). Talks about laptops, but it's the same nonetheless.
Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.
Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.
Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)
Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.
If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.

One of the worst things you can do to a lithium battery is discharge it completely. They don't suffer from "memory" yet every time someone here in the forums complains that they are getting crappy battery life the instruction to discharge and recharge to 100% before clearing stats pops up.
For those who are interested here is an article that explains in detail.

My main question- Is there some function in android that looks at the maximum depth of discharge level of the battery or is it that most people don't understand the characteristics of L-ion and confuse them with those of Ni-Mh or Ni-Cad?
I want to know because if I need to completely discharge to get better perfomance, despite the reduction in charge cycle lifetime, I will do it but only infrequently.
I've only let my battery discharge completely once, and it wasn't on purpose. From the posts I see here I think I get above average battery life. About 18 hours miui before I go for the charger and on 2.2 roms I'd get 20 hours and still have 40% or so to go. So no I don't think completely discharging your battery does anything for battery life.

I have never run mine down completely. Gotten it to about 6% but that was because I was fighting ROM flashing problems. I usually call 25-30% enough for me and plug in then. I am also getting 30 hours out of my 2.2 with a good deal of use. I used to have a Motorola and their batteries are total crap. If you EVER let it get down below 10%, it took some real work for it to charge correctly and boot up. Even as much as a hardware mod where I have had to cut the wires on a USB charge cord and charge it rigged up with the wires pressed against the battery and prongs in the phone. Very dangerous, but worked for a last resort.
Discharging the battery is not for the sake of the battery,but more so for the ROMs data and how it acquires the battstats usage. I only run it up and down and clear stats when flashing a new ROM, but I do use my phone moderate to heavy daily and have had great success in battery life the way I calibrate it.
The solution I think is to use a larger capacity battery and regulate it to narrower window of operation never fully charging or discharging.
The fastest killer though seems to be heat.
I have read several times that your phone does not fully discharge the battery...that there is still a minimal amount of charge,not enough for the phone to opperate but enough to not damage the battery when it shuts down
Maybe the batterystats file can be saved after being calibrated once and then restored after every wipe oor flash.. that would save some time aabd according to you guys, batt life too
Sent from a cell tower to the XDA server to you.
I've only ever calibrated my a few times and only after flashing a new rom. I never run my battery down after resetting the stats. I just use my phone as I normally do. My understanding of calibration is that it's not about squeezing more life out of the battery despite what most people think but of getting a more accurate measurement of the battery's actual charge. Also while it's true that the phone will shut of before the battery is completely discharged damaging the battery, allowing the battery charge to drop that low shortens your battery's life and decreases the amount of charge your battery can hold.
What gets me is I also read somewhere that for optimum battery life you should keep your battery level somewhere between 70%-40%. Of course that doesn't stop me from charging my phone to 100% everyday. I don't remember where I found that article but I'll post a link if I can find it again.
The reason this bad advice about completely discharging your battery persists is probably the same reason people keep recommending automatic task killers.

Discharging the Battery & Running the Battery Dead is 2 Different things!
We recommend running the battery dead ( Phone Shuts Off ) & recharging while off to train the Android OS from Full > Empty..
Running the Phone until Dead is not Going to hurt the Battery in anyways shape or form despite what you may think or read!
The Reason is, the battery is never fully Discharge & still holds Voltage.. The Calculations of Charged / Dead is at the Kernel Level, so even when dead it still has a 3.4v still or roughly..
As long as the kernel isn't tampered with, discharging the battery via the Phone will never hurt the battery period!
Now, Based on the link you posted you would have to run the battery down past the safe discharge point.. Via some other means of killing the battery, other than using the Phone.
To help ease your mind, Remember this:
~ Charge levels is controlled by the kernel
~ Even when Phone powers off, there is still plenty of charge in the Phone's Battery
~ Battery is never Fully charged, as this also hurts lithium batteries
Roughly every Android kernel does not let lithium battery get below 3.4v and at most 96% charged.
Hope this helps,
~Eugene
If you are still concerned wait until your phone turns off and stick your battery on a meter. You will see there is still power left in it...
My original battery that came with the phone got great life, then couple of months later it was discharging in like 2-4 hrs(froyo), so I called, they sent another one free...5-6 months later that one started doing it as well, so I pulled out the old one from the drawer, it powered on at like 85% ! and I was getting crazy ass life out of it on miui over 30 hrs one time...now that one is acting up again, so I'm going to try to swap again..lol...maybe there's something to not using them for a while...
I've used diff roms and combinations of draining/recharging...calibrating, not calibrating...it's always different results..honestly I don't think there's any rhyme or reason to it other than the fact that many vibrants have diff hardware and there will always be some weird quirk on a per user basis...
As far as hurting it by draining it all the way, I hardly think that's the case seeing as with both batteries I've always let it run down...not on purpose but there has been many many times I've plugged in at 1% or had to power back on because it died...charged it up and got 20-30hrs no prob..usually issues come up when flashing a new rom...
i think it all comes down to luck of the draw. ive had my vibrant since launch day, and i still manage great battery life. my battery is actually stamped 7-02-2010. every 2 weeks or so ill drain the battery completely, turn it back on and allow itself to die again, and finally allow it to fully charge overnight or 4 hours. i usually get a good 7-8 hours of constant use on cm7, or over 24hours if let on standby.
im still debating if i want to grab an epic 4g touch battery as well to increase it even more.

in there they tested in a store since the epic 4g touch battery fit into a regular epic 4g, if it would fit into a vibrant. only thing is you have to put the battery in facing inside, and it fits and works 100%
Yeah the Epic 4G batteries fit in our Vibrant's. You can buy knock-off one's (that work well) for 19.99$ US! Here's a thread about it...

Epic touch battery for the win. I've been rocking it for a few weeks. I was on miui and getting 14-16hrs. I recently went back to froyo and yesterday I got 12hrs off of a 67% charge.

Is it necessary to charge my brand new galaxy s3 before I even use it? I've heard two different stories. Thanks.
No.
People who say this don't take into consideration that the battery has been charged and tested in the factory, so what makes THEIR first charge special?
It is a li-ion battery. It does not need to be conditioned.
I personally used it directly without charging then at 5% I charged it. I have no problem and I get a really good battery life, better than most I have seen in battery thread.
Probably because you drained then recharged it... :silly:
I tried searching xda and also read up on Lithium Ion packs at BatteryUnivesity and pursued a few threads on battery storage questions at Toms Hardware and the like. Haven't found anything definitive though - I'd love the opinions of smartphone folks...
I purchased my EVO LTE today at Best Buy and it was completely discharged coming out of the box. So much so that it had to be connected to a mains charger for 5 minutes before the led would even light up. I had them get me another unit, claiming (I think rightly) that being fully discharged was not good for the battery... they acquiesced, but the second phone was exactly the same.
So I let it go... one powered up it behaved normally - I'm charging it fully now. I have 30 days to return the thing though, and with the non-user-replaceable battery I'm considering it. At the very least it seems to indicate that the things were in storage a LONG time, either at Best Buy or back at HTC (li-ion self-discharge fairly slowly), or perhaps that they went through some inappropriately high temperature storage or something? Am I being a complete technological hypochondriac or is it reasonable to want them to produce a phone that wasn't completely discharged in storage?
Any thoughts appreciated...

As a BBYM employee, many of the evos come dead. non removable battery has this shipped and sucking on power even shut down. Mine, however, turned on right out the box. but if its dead, its not necessarily defective.
edit: 14 day return with sprint
I'm a EE student and have done many papers on all types of batteries. With regard to your concern, the same thing happened to me at BB. They always come with a surface charge, and my thoughts are that either they did not charge the batteries long enough, did not charge them at all, or they charged them, and the charge depleted through temperature, time, etc.
I would not worry one bit. Things to keep in-mind with Lithium ion batteries is to avoid depleting them. Always charge them before they shut down on u, and there is a point where u can burn out the safety circuit these batteries are mandatory to contain, and the battery will no-longer charge.
Lithium ion batteries lose somewhere around 3% charge a year, and more if stressed. No doubt the battery will serve u well the length of time u own the phone.
Thanks
Thanks for both of the helpful replies... put my mind at ease.
Ok, I know my phone has battery-releated issues though im trying to figure what is the source and replacing it immediately.
I'll list couple of my chekcs around it:
Having it on charging barely gives the charger the "current heat" its supposed to have with it charging, therefore - resulting in a slow paced charging.
Disconnecting it from the charging port drops the battery down to 10-50% in some times, 60-80% the other times, but there are times that it's going down just to 99% or even keeping it at 100% like it should be.
Ive checked with the charging current app and I've seen it around 200-300, and after disconnecting and reconnecting it couple of times went to around 700-800, probably the reason for the slow charge.
Now my main problem is actually the 2nd one, I dont mind if my charging speed is slow, but I want it to deliver. are those battery drops related to the charging current? my main suspictions are the trickle charge cycle, that if the charger gets 200-300 mah charge, and it calls for a trickle charge, the amounts for it arent enough to keep the phone up even at minimal use, and report a fake 100%.
I havn't tried a different cable yet since I dont own any (same for charger) but if I will get any new cable, is there any rule I should follow to know the quality of it? like slimmer/fatter ones as an example?
And how do I know its not the battery that reached its cycle cap?
Thanks in regard for anyone who contributes to this post.

Search and read, same question asked a thousand times. Replace charger, lead and battery -done.
I have already searched for it for couple of threads. I have seen that it's a procedural solution but the main thing I'm trying to eliminate from the checklist is a bad charging port and board. Since my cousin already had that problem and he sold his phone it gave me that sort of red light and I haven't come across of a way of diagnosing it "without a cost" for the parts, I'd buy the pays only if there's no possible solution to diagnose it because those parts are quite expensive here unfortunately :/
how about battery calibration?
try that, and maybe your problem because u playing with tweaks or kernel maybe?
also try, install new custom roms. and format your system data
maybe it'll works

I think its battery issue, cant say for sure, but it also dies up on around 30% now (changed to 4.3)
I own the phone since april this year, and a friend of mine told me she had similar issues and after replacing the battery, it worked out flawlessly.
Also note that my phone is plugged in the charger for a lot of time and I barely plug it off (might be an issue as well)
Okay so I've switched the cable and the app shows flawless 1amp charge.
question regarding it:
if the phone is charging flawlessly like this. Could it eliminate my flickering screen and phone hang issue? (Due to "bad charging quality" if that lesser cable? )
