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.

May be a noob battery question

Can someone explain why my battery sheds the first 10 percent from full charge within a half hour or direct me to a post that could explain this?
Sent from my PC36100 using XDA App

From what I've read, there's a chip inside the OEM batteries (the ones sold by HTC and included with the Evo) that prevents the battery from maintaining a full charge. This is because maintaining a full charge can overheat and overvolt the battery and cause problems.
Thus, when you unplug, your battery drops to where the charge actually ends up when the chip stops the charge from destroying the battery.
We used to have SBC kernels that rectified this problem, but after a couple of idiots forgot the part where it says "this may harm your phone, use with caution" they went on a terror-filled witch hunt and had them all taken down.
So, until there's another way, you're stuck with that buddy. Best of luck.

this is one of the more discussed topics nowadyas, or more the fix is.
so, li-on batterys like the evo one, can be damadged/metallic plated by containing a full charge for an extended period of time. so, battery manufacturers made charginng cycles, so once the battery is full, the charger will fully turn off until it has reached 90, and then power back up again.
recently, ms(numbers i cant remember. confusing username) made sbc (superior battery charging) kernels, that trickle charged, so your phone would sit at 4.2mV and not cycle. there has been much controversy about these, including some finger pointing and borked batteries (mine has never been the same since using these, but i really dont want to blame ms########) have lead to most if not all links being removed from the xda. too bad.

Thanks for the info guys, I just flashed a different kernal and did some set CPU clocking tweaks that have made me over joyed but for now it seems that the first 10 percent will have to be sacrificed, before I rooted my phone I got almost 18 hours out of my batt using juice defender I'm hoping for similar or better scores but I can't complain too much with the performance now

Easiest way to fix the instant drain is to unplug your phone when it has a full charge. Let it drop to around 92 percent <---My personal preference or you can wait about fifteen minutes. Plug your phone back in and wait for the led to turn green and unplug it right after it turns green. BOOM! All problems solved!

Good humor man....
If your phone was at 100% for a period of time, you would feel more at ease about using it. That would bring about three things.
First increased network usage. Secondly increased phone position among its competitors because of one. Thirdly an increased consumption of batteries, since batteries are based on a chemical reaction which is limited by design. You don't have to be a rocket scientist to understand it. Go to a university chemistry department and they will point you in the right direction. No flashing of internet credentials.
So you want a solution? You can't handle a solution.

Is the trickle charging kernel working for you without any negative effects?

Hello,
I was just wondering how many people use trickle charging and what percentage of the people that use this kernel have had bad effects. Post a reply or vote on a poll.
Thanks
Edit: How did this get into the android development forum. I meant to put this in general. Please move it there.
Thanks

I've used it on the Stock & Extended battery without issue. msm####'s SBC-15 kernel.
Well over 2 months now.

I've used it on the stock battery for about 2-3months now with no noticeable side effects. Battery stays at 100% for a little while, instead of dropping 10% depending on where the battery was during it's on/off charge cycle with non SBC kernels.
Mod alert to have the thread moved. Triangle in the top right corner of your post.

Greatest kernel there is. Have used them for 3 months or more with stock and extended and have had no issues what so ever. Except for amazing battery life.

So far so good. I am using the latest SBC V7 right now on my 3500 extended battery. My Rom is myns rls1. I had 100% for a good 2hr and 10mins or so.
Sent from my PC36100 using XDA App

I am pretty sure the so called "problem" with SBC kernals is a result of people buying cheap crappy chinese batteries, having one or two die, and not wanting to be blamed for them buying crappy batteries blamed something else. "OH SBC DID IT!"
just my 2 cents since this has only happened with a few batteries from my understanding and they were all cheap chinese batteries.

100% for 2hours? How much use?

I have been using SBC since the day it went public. I use it on a stock battery and a cheap a$$ eBay battery. Never had a single problem, longest i have went was at 100% was around 7 hours (0 use of course).

I have been using SBC since it was public quite a while back. No problems except better battery life.

I didn't use my phone for the 2hrs after I took it off the charger. I think I can get 20+ hours with moderate use. I think this kernel is working for me.
Sent from my PC36100 using XDA App

Just switched like a week ago, I just take it off the charger before I fall asleep, don't want it on the charger for 7-9 hours. No issues yet. My battery was at 100% when I took it off the charger last night. I checked my Facebook & did a couple other things for about 20 mins and then turned wifi off & went to sleep. When I woke up 9 hours later it was still at 100%, and stayed that way for another 20 mins of use. Best battery life I've seen in a long time.

Been using SBC kernels for awhile now, on multiple roms, and experiencing AMAZING battery life. With zero problems twords stock and 3500 ma batteries. I run this kernel on my company phones that are rooted as well. on average over 10 devices at a time with 0 compaints to date.
Vaelpak went back to a crappy kernel on his new 3.2 and my battery life started sucking it up again. Flashed back to SBC for Netarchy's 4.1.9.1 Non-HAVS v7. Ive found that to be the best when it comes to draining.
Even under heavy use I still get a solid 12 hours of battery on my 3500. Thats running GPS, Wifi, wifi tether, lots of emails, texts, and other communications on a busy day. During slow times Ive gotten a single charge to last 57 hours of light usage. That was with wifi and bluetooth enabled the whole time and juice defender running as well.
I have since recently dropped juice defender, and only using SBC, and seeing ~ 30-35 hours before full drain on normal usage.

[Q] What is the best kernals for Cyanogen mod 7 rc4

Hi I've been looking around to find good kernals while running cyanogen mod 7 rc4. Some of the kernals I install like netatchy gives the screen a weird flickering. Can someone suggest a good kernal that's overclockable and stable. Thanks

Netarcys kernel really isn't for cm7 that's probably why its flickering. You should try savage zens latest sbc or non sbc kernel or tiamats sbc kernel both are pretty good. I'm running the tiamat sbc 3.3.4(great battery life) and I'm pretty happy with it.
Tiamat link. Be sure to get the evo version because he does kernels for the incredible also.

In a nutshell, sbc is a method of charging that allows you to "fully"(trickle) charge your battery. Normal kernels really only let you charge to about 90% for safety measures; while sbc lets you fully charge letting your battery completely fill. There's a few threads that talk about it if you search around to get more "details". I've been using them for months without any problems whatsoever. Good luck

Honestly I get great performance out of the stock kernel.

That happens to me sometimes but not all the time. I believe that's still a problem with cm7 in general though. For best results I recommended going to settings/ cyanogenmod settings/ performance/CPU settings then use the "smart ass" governor. It has provided me with the best overall battery/performance. I also have my min freq at 245 and max freq at 1152.

Those are also my settings, I've discovered my evo can't go beyond 1.15ghz without locking up. I've been trying to get to 1.2 but no go

I don't really put so much stock in scores anymore they don't mean anything to be honest. Dirk used to be a score whore but I just removed the apps so I wouldn't worry about it anymore. I came to terms that my scores won't go much higher then what they already were. Just ran 40 mflops and 1220 bench.

I just wanna correct this misconception because it led me astray and it took a good amount of research to realize this was wrong.
All kernels will charge the phone to 100%. That's not an issue. What happens is, once they are charged to 100%, they start draining battery again, and coupled with the fact that li-ions inherently lose charge over time, and the fact that most people haven't conditioned their battery's memory by properly charging it, by the time you pull your phone off the charger it's already lost that 10% (give or take).
Trickle charging hopes to fix this by "trickling" a small charge into the battery constantly once it hits 100%, to compensate for discharge, so that it stays at 100%. The problem with this is, it pushes a current through the battery constantly, and that tends to shorten the life of lithium-ion batteries over time. You may get better immediate battery life off the charger, but you'll kill your battery quicker. Come months from now, your battery life isn't going to be what it should, whether you notice it or not.
If you want to minimize the discharge, you can take a couple safer steps:
- Condition your battery. Charge it to a true 100%. This will mean turning the phone off and on a few times while it's on the charger to make sure it's actually at 100%. Then completely discharge it until the phone cannot turn back on. Do this a couple times in a row, and repeat every month or so. This conditions your li-ion battery's internal charging memory so it knows its true charge potential.
- Charge your phone while it's off. It won't drain nearly as much battery this way, so when you're ready to take it off the charger it'll be much fresher.
- Avoid prolonged charging and continuous charging, because it can confuse the li-ion's internal charging memory. Rather than re-charging it when it hits 60%, let it drain as low as possible before you bother recharging it. Bursts of short charges don't harm the battery, but they make it "forget" how much it can be charged.
In short, SBC kernels are bad for your battery.
---
Also, Savaged-Zen 1.0.1 BFS no-SBC has been the best kernel I've found for the Evo 4G. Granted I haven't had this thing that long and there may be another gem lying around somewhere, but given the popularity of SZ, I doubt it. It's a very good, smooth kernel. It's giving me the best performance of what I've tried (most of the popular ones).
As for CFS vs BFS, flip a coin. Some will swear CFS is smoother, others will swear BFS is supposed to be smoother. BFS gives me more responsiveness personally, but I think it mostly depends on your workload. I keep scarcely-used tasks killed and I don't use widgets, so the lack of many processes may be what makes BFS better for me. Try both and see which feels smoother in daily use.

That's a great plan man. I visited the savage zen kernel thread earlier and some are complaing about their newest build causing charging issues or something along with 100% wake time idk. If you give it a shot use their 1.0.0 instead of the 1.0.1. Just give the kernels about a week and see how well they hold up. Its mainly about personal preference(sbc or non sbc) I'm actually testing the tiamat sbc but I was previously on savage zen. I like to give all kernels a chance(1 or 2 weeks) to see how well my phone performs with them.

Ok well ill just wait till Friday to install a new one then and see how the Zen works out

Cm7 question

I am running the final cm7 rom and I am wondering if the kernel that comes with it is an sbc? Reason I ask is I am using a 3500 battery and only getting 4-6 hrs use and based on other posts it wont fully charge without sbc. If it is not an sbc any suggestions on a play nice sbc kernel?
Sent from my PC36100 using XDA App

Its not sbc, but the Tiamat kernel is nice.
Also charge your battery up to 100%, clear battery stats, then let it died completely, and charge back up to 100%.

ive combined this kernel (with sbc) with cm7 and various themes and have always been easily able to (overnight) charge my phone and go all day with moderate usage (3500mah from ebay)

btw, make sure you wipe battery stats, charge all the way up, discharge till it shuts down on its own and then give it 2 days for the kernel to (settle in)
