I just received my seidio 3500 extended battery and extended rugged case. What's the best way to charge it using the stock phone charger? I've seen alot and most reviews and threads recommend external charger. I don't want to have to deal with that and shell out more money. I don't remember the link but I've also seen how your supposed to charge while on till full then unplug, turn off the phone then charge while off for an hour turn back on for 2 minutes while unplugged again then charge again for another hour while turned off again. I'm new to the evo and extended batteries so any help is appreciated. Thanks.

I charged mine up til it was 100%, then monitored the battery widget. It kept going at waveform like this for another hour and a half - /\/\/\/\/\/\/\ - however as time went on, the peaks would be at lower and lower amplitudes. Eventually, the charging current decreased significantly, and there was an occasional spike every 5-10 min. At that point, I turned it off and let it charge for another hr or so. Rebooted (while still plugged in) into recovery, wiped battery stats, then rebooted to the desktop. Once the phone was fully booted, I unplugged.
I can get a good 2 days with light usage, or a solid 1 day with heavy. There after, I charge it til green, then give it another 1.5-2 hrs more - You can tell by the battery widget when it actually stops charging.
Note, i'm not using an SBC based kernel.
What battery widget are you using?

It's all bull man you dont really need an external charger. When I was in the process of getting my 3500 mah I was also preocuppied about the external charger, however I began to use and you really dont need it.
Just understand that when the 100% sign comes up and the green light turns on it's not really charged all the way, the phone can only recognize upto 1500 mah..if I remember correctly. You have to leave the phone plugged in for another hour or so for it to actually get it's full charge.
Even then, it will seem like it is not working because the battery will go from 100 to 90 in around 5 minutes ITS CRAZY!! But dont worry thats a fault on HTC's part. After that 90% mark the phone will have really good battery life. I usually get around 15 hours of heavy usage, extremely heavy trust me! If you just use it for phone calls and dont really use GPS and stuff you should get maybe a day and a half.
So dont worry about the external charger, it's not true. What I did when I first got the battery I charged it 100% let it drain all the way and then recharged it. This is just so the phone understand the capacity of the new battery. At first it may seem a bit "iffy" but dont worry it'll live upto it's potential.
Hope this helps. Later!
Thanks obloivior72,
I'm going to charge it up now and try it.

Just remember let it sit for another hour after it says it's full, Actually leave it for 2 just to be safe. I can't emphasize this enough! Glad I was able to be of some help! Enjoy your new battery.
Graph looks something like this.

Each tick mark on the X axis is 10 minutes. It took about 2 hrs to get the battery from 20% to 100%, then another good 90 minutes to really complete the charge (light green during this time).
Im using an SBC kernel. Its a little bit taboo on these forums right now but if you can get your hands one one it will def do the trick without jumping through hoops. Just read up on it first. Search the forums and do some reading about it before flashing. There's a lot of conflicting opinions on both sides about it so read about it then you decide.

I looked into the sbc kernels but with the bad info and everything I cant make the jump. I charged for 2 hours after full so I'm going to test it now till it dies while running calkulins 1.7.7. I'll let everyone know how it goes. I appreciate all the tips. Hopefully this makes my evo complete.

This is what Seido told me to do if it isn't charging adequately:
"Please try to fully drain the battery until the phone completely shuts off automatically and then charge with the OEM AC charger that came with your device. Repeat this process 3 consecutive times. This will recondition and also recycle battery usage for best performance.
Thank you,
Seidoonline Technical Support"
However, doing this when the battery is new really doesn't do any good. It would be useful after some time using it since these are "smart batteries".
Just charge it normally and should be good to go.
Ok I got a new extended battery what souls I do to condition it so my phone will charge to to 100%
I'm in rooted so can't wipe battery stats
Also is there a way to check its capacity so I know its fully charged
Sent from my PC36100 using XDA Premium App
Since you aren't rooted, best you can do is:
-Charge to 100%
-Let the phone die, so its manually turns off
-Charge back to 100%, use as normal
And not really...
Aww, c'mon Roxx, you know that's not the way. Even HTC says don't let your battery die.
Let it drop to under about 50%, then charge for 8 hrs, while off. Unplug, boot up let it settle in for a few mins, then power down and charge for another hour.
Then boot up.
That's the best for unrooted phones.
I just feel odd about killing batteries and anything 4 my 2nd question good app to monitor my battery......most don't have good info

Well it gives the lithium batteries the best chance to discharge, then started the process over. Continued practice of that is bad, but for 1 power cycle, it is okay. Though through normal usage, you should charge it whenever it gets low

Battery Moniter Widget is the best, and I don't think you need be rooted for it.
Rexx, I agree that doing it once may not be bad, but I say why take chances, ya know?

Yea a good app for non rooted phones.
And well fair enough, especially for those less experienced.
This was posted awhile ago on the xda EVO 4G forum and it seemed to work for me.
1) turn ON Phone & charge for 8 hrs.
then
2) unplug charger - turn OFF phone & charge another hour (1)
then
3) unplug charger - turn phone ON, wait (2) minutes then,
turn OFF phone & charge another hour (1).
Your battery has been set and your battery time should be doubled.
This as per HTC
I have also found that using the app: Juicedefender
works great even with its default settings.
Good Luck...

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%?

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).
Hey guys! Just gotten my note 2, and gonna drain the battery down soon, should I plug it in and charge for 8 hours straight from zero? Should this be done with the phone off? Or this doesn't matter anymore?

This is not needed anymore.
if the battery takes to long to kill then simply its already calibrated
many people don't know how a none-calibrated battery acts and think "battery life is great but it will get better later!"
if anyone of you happened to have a nokia phone in year 2000ish and still have it around i recommend you to go get a replacement battery for it and see for your self
unless the new battery jumps from 100% down to like 80/70% in no time then take too long to drain from 10% or something like that (in short battery acting weird)
then its already calibrated which is the case in all new phones/batteries
TL;DR
unless the battery is acting weird and not taking too long to kill then you dont need to do that

This charging a long time first usage is also an old thing from the old nicd and nimh batteries..
in fact li-po and li-ion wont even charge after they are done, overcharging them means they explode/burn or get damaged.
there are built in safety features to prevent that.
and pulling it down to 0% means nothing since modern nimh, li-po, li-ion batteries don't got the memory effect.
actually going down to 0% would only test if the low voltage cutoff works as it should or if you damage your battery.
no need for that!

I know most of you already notice this but if you don't:
In Setting/ Power saving mode, check the "CPU power saving" then your phone will be limit to 1.1GHz max from 1.6Ghz.
I would suggest to tick on the "Screen power saving", "background color" and "turn off haptic feedback" to save some extra juice.
LTE on. 24h unplugged. 75% screen brightness. Full heavy haptic feedback. Heavy gaming and Internet use. Phone calls. Texting. 3D live wallpaper. Still 7h screen on time before the phone finally had to be plugged in.
I don't know what you use your phone for but I'm going crazy on mine and can't kill the battery. If you need more juice, then more power to ya. I can't fathom why.

Try a day without charging your phone at your desk. Yesterday I pulled in about 7 hours of on-screen time. That's with LTE and anything else internet intensive you could imagine. The only way you'll overcome that worry you have is to test it out yourself. I'm sure you won't be disappointed.

You do know to "remove bloat" all you had to do was go into the stock app manager in settings and disable anything you didn't want. That is actually a much better solution than "freezing" with TiBu or removing altogether. I'm not convinced root and mods are 100% stable yet. Most people reporting decreased battery life are those that have rooted or modded something. I'm still 100% stock with ATT stuff disabled and batt life is still 7+ hours.

Even bare stock I wasn't getting that much screen on time. So far I've only rooted and changed the kernel. Though today my battery life is starting off good. Yesterday I ticked the power saving option for the screen. I'll post an update tomorrow.
Today I was on for 5.5 hours, screen time of 2.2 and was at 54% with Power Saving On
So I went to bell and grabbed another battery
Time will tell if that helps
I could never reach 5 hours of screen time but could have the phone on for 30+ hours
I cant wait till we get more developer support, I used Francos Kernel with my galaxy nexus and it improved battery by 30 % and made my 8 hours overnight use only 2% battery. I was using 12-17% overnight with my note 2 asleep. Aside from kernels and roms I use this phone exactly the same as I did my Nexus. wifi off, bt off, gps on, push email on, auto brightness

Lithium Ion batteries actually do better if you don't charge it constantly. In other words let it run down a bit before charging. You don't want to always keep "topping it off". But in general these batteries are much more resilient than others.
Just do some research. There's lots of info out there.

Umm, no, it does not. You are stressing the battery out. Unless needed, dont keep the battery below 20%. Its healthier to charge the phone sporatically throughout the day.
These aren't nickel batteries...they dont need to be trained or "cycled"

I'm a battery test engineer so I have played around with Li-ion batts.
If you can keep the phone at cool temperature and charge at 40% and stop at 80% then keep doing 40-80, your battery will last double long

Agreed. Full discharges are not necessary for lithium ion batteries. Full discharges were needed for NiCad or NiMH batteries as they suffered from memory effect. LithIon doesn't suffer from this. With that said, a lot of experts do suggest discharging a LithIon periodically, maybe once a month or every other month.
