Just got my seidio extended battery what's the best way to charge it?

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.

Bad battery?

I charged my phone overnight and when I woke up the LED was blue but I didnt check the % because i was rushed. When I got to school, the % was 25. now it is going away fast... Really odd, will calibrating help or is it the battery?

U can try calibrating the battery. Try charging it with the phone off, and if u get the same results, than its the battery

What lord said. I was seeing an issue where the battery would drop 8 percent as soon as I took it off the charger. Then if I rebooted, the battery would drop significantly so it was never reporting the correct battery percentage. Calibrating didn't help.
Ending up going with the Epic 4G touch battery and it's been a lot better. They are going anywhere from 15-25 bucks shipped:

If the battery is over 1 year gold's expects a 10 to15% reduction in its capacity. Normal with nickel cadiums.

Simple Guidelines for Charging Lithium-based Batteries
A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
http://batteryuniversity.com
Charge at a moderate temperature. Do not charge below freezing.
Lithium-ion does not need to be fully charged; a partial charge is better.
Chargers use different methods for “ready” indication. The light signal may not always indicate a full charge.
Discontinue using charger and/or battery if the battery gets excessively warm.
Before prolonged storage, apply some charge to bring the pack to about half charge.
Over-discharged batteries can be “boosted” to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.

Wow! You are like Mr. Battery or something!

Hahaha...I couldn't remember all the info about the lithium ion cells (I read a lot about awhile back). So I decided to post some factual info about. That way it helps everyone and anyone

I hope you are not using a generic battery. I have seen those things spontaneously short themselves. Whatever you do, don't take your battery apart and attempt to rebuild it yourself. Chances are, you don't know what you are doing. I have seen people attempt to fool around with batteries and get hurt.
Remember, lithium ion batteries are a lot like horses stomachs:
1. Empty them often.
2. Fill them often after emptying.
3. Never leave them alone with a full stomach. (Always leave them alone half full).
4. Use them every day in some way.
5. Never ride them hard outside of MacBeth Castle and then walk them for a mile so you don't get killed by Lady MacBeth's agents. (If you use them very hard for a long time, and then use them sparesely afterwards, don't expect them to be stable...and don't expect not to get murdered outside of your castle).

Sounds like a phone charging issue. I've never seen this cuz my phone charges my battery in RARE circumstances like once a year. 4 batteries externally charged well worth the money... ;-)

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

Thanks a lot I got my retail set from a carrier, so glad to have joined the note 2 community coming from the s3 :X so I just charge it up to full as per normal yes?
Sent from my GT-N7105 using xda app-developers app

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!

Batteries that comes with the latestmpgones these day do not need to be charged for 8 hours!
Just charge it till its full and continue to enjoy it!

You can preserve the life of you battery by not fully charging it and you can damage it by draining completely. I've no source for this information.

New issue..

Okay. Got a new problem. I have my phone plugged into charger. It says it's charging. Shows the lightning bolt thing on the battery too. But while I'm using the phone, even while it's plugged in, the battery % goes down, instead of up. But if I just leave it & not use it while it's charging, then the % will go up.. Just extremely slow. I have a new battery & a new charger. I even tried my old charger & it still does the same thing. So why would the battery go down, eventho it's plugged in? I don't understand. Please help
Sent from my SPH-D710 using xda app-developers app

It may depend on what your doing with the phone. If your running a system heavy app like the browser, camera, Facebook or a game that has a lot graphics and the processor is cranking, the charge rate may not be sufficient to replenish the battery.
Especially if the battery is way down to 10% or less.
My wife does the same with angry birds. You have to let the battery catch a breath and charge up.

If you are using your phone a lot while it's charging, especially if the screen is brightest, battery sucking apps, cruising the net, a lot of texting, then chances are your battery is draining faster than its able to charge. Try this. Run your battery all the way down till it dies. Then let it charge completely full, then run a battery calibration(download this from app store before you let phone die). It will calibrate it when it's at 100%. That should help some. But if you use it a lot while charging, it very well may discharge faster than charge. But try the above, it should help. Good luck

I have never had this issue with the stock charger for this device, even when using high intensity apps. It will happen if you are using a 3rd party charger, even of it says it is a full 1 amp output, it cannot keep up while using the device. Make sure you are using the stock charging block. If you are, try replacing it with a new OEM charging block.

What brand of new battery and where did you purchase it?
Sent from my SPH-D710 using Xparent Cyan Tapatalk 2

It's a Samsung battery. Got it from sprint.
It was fine, until about the past few weeks. That's when it started doing it. & the battery will never be below 10% when I'm using it. It could be at 70% & will just start going down while plugged in. It can be at 100% and it will be plugged in. I do one thing on it & it goes down to like 70% suddenly. Then gradually go down more.
I will try calibrating it
Sent from my SPH-D710 using xda app-developers app

Try taking the battery out and leaving it out for 10 minutes. If that doesn't help then I suggest taking the phone and battery to Sprint and have them check both the phone and battery. It could very well be a defective battery. Are you running a stock rom?

[Q] strange battery drain (updated)

I'm not complaining about battery life bit I just fond this strange how with nothing running my phone went from 20% to dead that fast. Phone was locked and in my pocket. Anyone have any ideas? It's also not the first time this has happened either just the first time I thought to get a screen shot of battery usage right after
**Update**
Now my phone is dying at random :/ it does it from 50%, 30% etc. Any suggestions (i.e. battery calibration, full factory reset) or should I make it stock again and get a replacement?

Sent from my XT1080 using XDA Premium 4 mobile app

Batteries are gauged by how much voltage they are pushing in most tests. Though from my hobbies of electric rc cars, I've learned that batteries can change their voltages simply from a temperature change. While these changes may not be significant, they do represent differences and used to play a big part in my fifteen minutes charge cycles. It's harder to receive a positive rating in a cell that is low on power than it is with one on max charge. So if I'm down to twenty percent or so, I use my phone very sparingly. Has been pretty trustworthy for me over the years.
Either way, suspicious battery drain is usually a rogue application sitting there eating resources as the phones we use do seem to monitor battery life pretty good compared to the old voltage meter methods.

I found the htc-Facebook app drains funny on the battery. When I loaded bonestock, then loaded Facebook from the play store, it helped my battery. I think it's the way the htc-Facebook interacts with blinkfeed.
Could be completely of base, but I know the htc loaded Facebook is slightly different.

I assume you had a good signal everywhere you went? Nothing drains a battery faster than being in an area where there is very low or no signal. It constantly tries to connect and it will KILL your levels very fast. I see this quite a bit in my work place. Employees with Sprint and many times AT&T will complain about their battery dying at work only to find out the phone was constantly searching for a signal.

You know, I totally forgot about that. I used to have that issue with Sprint myself. Killing the data would eliminate TONS of battery usage when I was at work. Now that I'm on Verizon, there's never much problem. But he's completely right. If you're not getting a quality signal your phone may be searching and that can be an all day thing which just eats a battery alive.

I am in a near perfect signal. I'm pretty sure its has nothing to do with coverage. What's strange to me is the phone immediately dies. It will be at 50% and then the screen goes black and won't come back on. Once I plug it in the phone finally comes back on and is at zero.

I'd have to search around, but taking these batteries all the way down actually reduces their effective life.
Sent from my DROID2 using xda app-developers app

Basically, the more you drain the power before charging, the less charge cycles the battery will have. Someone who charges at 75% compared to someone who charges at 25% will have more cycles over the life of the battery. I can't remember the exact numbers, but there's been plenty of studies on the issue. And if I'm correct charging at those numbers, the 75% will have more than twice the charge cycles over the life of the battery. The biggest battery killers though are actually higher amperage charges. One study showed more than five times the life cycle at 3.7v per cell compared to 4.3v. And the charging required to power the higher voltages actually cause more damage over time than the extra mah output is worth. The HTC one has a decent setup and the stock charger doesn't over feed the cells. But in not sure if it will make it to the 700 charge cycle that a two year contract may leave a user with.
