Did I condition my new battery wrong?

I bought the yoobao 2800mAh and I'm wondering if i conditioned it wrong. Because when I first put the battery in (it came shipped at 66%)... I knew I was suppose to fully drain it and then do a full charge. So I opened alllll kinds of apps. streaming shoutcast, music, google earth, gps, synch... All on to drain the battery, and it took FOREVER! I was really happy, but after that, and the first full charge, it drains just as fast as my stock battery. I'm wondering if that's because of the way I drained it the first time.
I charge the battery as much as it will charge with the phone on, and then I turn the phone off to actually get it FULLY charged.

If you are rooted, you need to fully charge then boot into CWM and clear battery stats.
Do you BONSAI?

Mine was the same the first run through or so then it was amazing after. I think it just needs to get broken in. I know that that might not be true scientifically or anything but that was my experience.

I just wonder if it's draining so fast because of how I drained it the first time (in original post)
While streaming from shoutcast, I lose right at about 10 percent an hour. Regardless of the app I use for that streaming
[edit] ten percent an hour is if I do absolutely nothing else. If I send txts while streaming. I can go through 10 percent battery in as little as 20-30 mins

It is more likely that you have some apps loading and using data now that you fired so many up. Download Spare Parts and see if you recognize apps using your battery. Also get cpuspy to make sure your phone is going into deep sleep a majority of the time.
Do you BONSAI?

But I don't fire those up. The only time I did that was the first battery drain, so it would drain quicker.
The battery has gone through more than 5 drain/charge cycles now. I have spare parts. It usually says "running" uses the most.
I'll download the other app

Just checked that app (cpuspy) and the phone is going into deep sleep. It seems that when I have the shoutcast stream going it going to 200 mhz is most common

Is this normal?

When ever I unplug my phone the battery percentage drops to 99% no matter what. I could have it charging with the phone on or off and it will still drop.

My phone is only 3 days old.
Sent from my SPH-D710 using xda premium

My phone's been doing that since the first day I got it. I wouldn't worry.

Just want to add something
The second you stop charging the phone starts using the battery. Even after one nano second it isn't 100% anymore. It might be 99.99999 but it isn't 100%. So, it isn't a problem, it is a feature. The gauge truly works.

oh oh oh! pick me!
i have some knowledge from my evo to bring to these forums! finally!
on my OG htc evo 4g, HTC built something called SBC (Superior Battery Charging) into their kernel. when my evo would get to 100%, charging would shut off. this is designed to prevent over charging and ''thermal runaway'' leading to bloating, overheating, and death of a LI-ION battery. my battery would drop from 100% to 93% in less than five minutes, operating normally the rest of the day. similarly, ive noticed this type of behavior on my E4GT. the difference being, if developed/programmed right, is that charging can be turned back on once it drops below a certain percentage (done on my evo 3d). thus, you can never have 100%, since it will immediately drop once no longer connected.
yay knowledge!
if you find my explanation too long/confusing, it all operates on FMS (****in magical ****)

Got my phone December 19th, and it does this as well. Makes total since though, Once you use even the SLIGHTEST amount of battery, you're no longer at 100%. Im coming from an Evo 4G as well, and ran SBC kernels. Totally agree with the post above me!

HTC kernel did not have SBC, or even built it. Only a few custom kernels had sbc support.

I think it has more to do with the rather unique Maxim chipset fuel gauge on Galaxy S2 phones than anything else.

yeah mine also like that.. it's just a little bit sux.. since the battery charge a loong time from 99-100% but drop immediately after i unplugged..

First 10% battery drain

I'm noticing on gummy and other roms I try that the first 10-12% drops fast then slows down to normal. No matter what kernel I try this seems to be the case. Anyone have any idea or maybe you could school me? Thanks community

When your phone is on the charger, it will charge to 100%. After it hits 100%, it will remove itself from the charger and run on battery. This will go down to a certain percentage (maybe 95%, maybe 90%), at which point the phone will reattach itself to the charger and charge back up to 100%. The drop you are seeing is when you take the phone off the charger while it is in the midst of one of these cycles. I would assume it still shows 100% battery but drops down to what it's really at.

Thanks but my battery doesn't get consistent until around 90 and lower so I'm sure your rite but why does charge to 100%
On my nexus s it stoped at 95-96%?

One way around it is to unplug it for a second and then plug it back in to top it off.

Or charge it while it is off

It's really not an issue, it's just how it works. It gets to 100% and instead of charging more and frying itself, it stops charging. When you take it off the charger at 100%, it's not really at 100%, it's somewhere in between 90 and 100. The reason it says 100 is that if you let it charge all night and it said 93% in the morning you'd have already called to Samsung to complain, as would have everyone else.

The HTC thunderbolt did this as well. To protect the battery, once it reaches 100%, it stops charging. Then once it hit 95% or somewhere in the 90s again I believe, it kicked back on. You have to bump charge. Though I believe once I started installing custom roms, the issue seemed to disappear. So maybe its in the code or something.

Seriously, bump charging will destroy your battery health.

Every phone does it. It is to protect the battery's life.
Batteries suffer when they are 100% charged and when they are really low.
That's why when you get a brand new battery is it charged about 50% because it extends the battery's life while in the shelf.

When I disconnect in the mornings it's always 97 or 98%. who knows when it stops charging in the middle of the night. but from 98% to 75% it is really quick. maybe because during that time I'm on the train listening to music and browsing the internet at the same time.
With iphone 4, I always disconnected at 100% in the mornings and after the train ride the battery was around 88%.

He was just saying that if you put your phone on for a full night of charging and woke up to see it was at 93%, you'd probably assume something was wrong and call the manufacturer. Chill out, he's not insulting or mocking you...

I didn't leave it on all night but he was a little offensive by basically calling me a complainer by saying did I call samsung already
I just wanted to known if my problem was rom or kernel or maybe even hardware but coming to find out that my GN is just like that was a bit of relief. I've owned a galaxy s,nexus s but this was the first time I've seen a Google samsung battery charge behave like this. No biggie was just curious

In the long run maybe a little, for how long most people keep their phones it won't matter though. This was actually something HTC recommended we do for the Evo 4G cause it was the exact same way.
I actually did have one of my batteries discharge too much to where it wouldn't come back, but all I had to do was take it in to Sprint and they gave me a new one for free.

I don't know how you got that from what I wrote. I was just saying that if you woke up and the battery said 95% after charging all night you'd think something was wrong with the phone, as would everyone else. The reason it says 100% is that the phone manufacturers don't want to explain that it's not a problem to a million callers a day.

The same thing happened to my brother's G2.
Then I remembered, It can be brought back to life either with high voltage or high current. I plugged in to my Touchpad's charger (which is 1.3 amps I think), and the miracle happened. It returned from the dead.

Not true.
The best thing for a Lithium Ion battery is to keep constantly charging it as much as possible. These are not the old nickle batteries of ~10 years ago. The internal circuitry inside your phone's charging system is what keeps the lithium cell in it's "happy range".
However, once a cell is outside of it's "happy range" one of two things will happen:
1) Thermal run-away; this is when an overcharged cell begins to generate it's own heat by consuming Lithium, creating more heat, consuming even more Lithium, creating even more heat, etc... When you hear of people's laptop batteries catching on fire in airplanes or where ever, it's usually because of thermal run-away.
2) Cell depletion; if a cell is discharged too low it looses it's ability to retain a charge. It's not a "Hmmm... my batter doesn't seem to hold a charge as long anymore" like the old nickle batteries, but it won't hold ANYTHING at this point.
In closing, there is nothing wrong with "bump charging" your Lithium battery. The charging circuitry has been HEAVILY scrutinized and tested for safety measures and will never overcharge your cell (assuming the HW is opreating correctly).

[Q] Battery Taking Too Long to Charge

I've had my N2 for a few weeks now. Suddenly, it has taken much, much longer to charge the phone. I calibrated the battery, drained it to 0 and plugged it in. 3 hours later it's still at 50% (and the phone is charging while off. Any suggestions?

Are you using the stock wall charger and cable that came in the box?

The reason the battery is taking so long to charge is because you ran it down to 0. If you want your batter to last longer it's best to use the 80 / 20. What I'm saying is use the phone down to 20% and recharge back to 100%.

May be a faulty battery. Contact Samsung (I'm assuming that by n2 you mean note 2) and they'll probably send you a new battery.

I only had one issue, yesterday, and it was that my phone showed 25 percent charge on stock white Samsung charger/cable and I knew it had been on the charger longer than that. I rebooted and it showed 74%. Not sure what the hell this was about.

Old rules by what standard? Anytime using lithium type of battry is best not to run it down to 0%. I guess you don't have much experence with them besides your phone. I use them everday for my hobby. Sure you can run them down to 0% if you like replacing them quicker.

Old rules were for NiCad tyoe batteries, where you did want to run them down to 100% and had to deal with other issues. If you do end up doing that Google search you will find the advice given is pretty accurate. Staying out of the high and low ends for long periods will give you many more cycles.

I know this would be obvious, but I figured I will ask anyway. Are you still running the stock kernel, or are you possibly running one without the capability to accept the 2.1A charging?

You would know if you were running a different kernel. You would have had to install it yourself. If you are All stock (ROM, AC adapter, cable) then you have something defective.
Here is my screenon time with everything running all the time on cleanROM with 6400 mah battery.

Batteries will last thousands of cycles charging to 100% from 50, but maybe 300 cycles charging from 0 to 100. Don't run your battery down so much. Charge it when you're not using it.

Note2 battery drain problem

Just like the topic says I just want to know how long should I initially charge the battery and how would I go about doing that if I don't have just a battery charger? It's a stock oem battery I just got from eBay and it didn't come with any instructions so I'm trying to figure out the discharge and charge instructions also so I don't fry this battery

No special steps necessary.

right. plug it in like normal. Some say to discharge oob, then charge all the way. i personally just let it drain 1-2%, then plug in and charge full uninterrupted.

What I meant was I just let it drop by 1-2%, not to that point. Imo on first charge there's just not a need to do a full discharge like some say. But when I plug it in I leave it alone till ready. Then first cycle I drop to 5-10% and charge fully once more. After that it doesn't really matter. (That first full cycle is just habit for me. I don't believe it's necessary though.)
Li ion batteries are much more forgiving than people think. Lots of incorrect rumors and info out there. That's why I suggested that link earlier.

Do note, if you drain 100 % or nearly there then after you plug in, the phone won't turn on for first 20 minutes or so. It will start afterwards.

I personally don't even care. I just charge it whenever I want regardless of what percent, and leave it charging overnight and get 100% when I wake up. The best thing about this phone is that it has a removable battery. If my battery ever dies, I'll just buy another one.
