I have av Evo flashed to Cricket running Jiminy IV for the rom, it is rooted and nand unlocked. My question is do you have to use a special kernel to use an extended battery? I bought a generic 3500ma battery and cant get it to charge. Any ideas or suggestions?
Thanks

well is your cord charger broken? if not then return the battery and get a refund or exchange for a working one.
The cord charger works fine for the stock battery. Hoping to get this figured out

You shouldn't have to use a special kernel to charge an extended battery; I've used multiple extended batteries and they all charged fine regardless of the kernel. I've heard that some generic extended batteries won't charge in the phone and will only charge in a wall charger, so perhaps that's the problem. However, that's not a problem with extended batteries in general. I'm guessing the problem has to do with the phone not recognizing the battery as compatible. Perhaps, there's a kernel that has a work around for that, but I'm not aware of any. It might be worth flashing a bunch of different kernels and seeing if any of them work. You might also want to try wiping the battery stats (shouldn't make a difference, but who knows?) and testing SBC vs non-SBC kernels (I think the SBC mod only enables trickle charging, but maybe it will somehow allow your battery to charge as well). If none of this works and you don't want to use a wall charger to charge it every time, it might be worth spending the extra money on a Seidio 3500mah extended battery; I know that one charges fine in the phone. Hope this helps.
What do you mean by "wall charger"? I have tried with the usb cord in my computer and the same cord plugged into the wall charger. I am not sure what else to try.

THe make chargers that you plug the battery into and then plug into the wall. You don't charge it through your phone. I think this is what he is referring to.
I am guessing that would mean like a docking station. I will have to see what I can find by way of where to get one and how much they cost. Other than that I am not sure what else to do. I have tried several kernels, but have yet to find one that will work. I am just hoping that it just needs a different charger. Thanks for the info

What I'm talking about is sometimes called a dock charger, but it shouldn't be confused with a docking station/cradle that the phone sits in and still charges through the micro-usb port. You take the battery out of the phone and put it directly in the charger, which plugs into the wall. It's like what you'd normally use for rechargeable AA batteries. Something like this: http://bit.ly/e8jXfQ. That's the best deal I could find.
That makes sense to me. Now I am wondering if I can find one of these locally or if I will have to go through ebay and wait 20-30 days to get it shipped to me.

If you don't mind paying a little bit extra you can get one on amazon here. Some of the sellers offer expedited shipping, so you should be able to get it pretty fast. I have one that looks just like this (I think it's the same one) and it works fine, but if you'd prefer a name brand one, you can get a Seidio wall charger here.
From what I've read about extended batteries you have to keep charging them past the time that the phone reads %100 since the phone only recognizes 1500mAh.

Not charging
i have my evo running CM7 rc4 and i just flashed savaged zen nosbc and my phone doesnt appear to be charging anymore can someone please help
Turns out it was a bad battery. Got a new 3500ma extended battery and it is working just fine

agree dont need special kernel for extended battery, mine was just plug play and charge....on a side note, after three months my extended battery bit the bullet last night...taking it back
I need to find a 3.29 rom for cricket so my battery doesnt drain as fast. I also need to get an external charger for my battery. My battery life is about the same with the new battery due to the way the Evo charges.

Just curious to those that use Pandora in their car and forgive me if this is n00b thread but I'm looking for any input.
First off, I have had this phone since launch but have yet to put it under heavy use(lots of email, gps, bluetooth, etc). So I'm a bit cautious about wearing down my baby lol. To the heavy use users, is battery life still the same or are you seeing drastic changes on how long it last?
Second, what set up(modem, kernel, rom, etc) should I use to run Pandora as flawless as possible? I will mostly use it when driving through the city(weekends) so I hope to get better reception there than at home...
Again, sorry for the dumb questions but I would like some input. Cheers!
I listen to music via pandora in the car. the batteru drain is very light. At most, you use 5% in 30 minutes. (At least for me). I always have screen off when I play pandora, though. And I have good signal where I live.

Don't know about your second question, but anytime you use any phone heavily (lots of everything you mentioned) the battery is going to quickly drop. Flashing most ROMs will improve your battery life, but not so drastically that it will stand up to a day of heavy gps/bluetooth/4g/constant email & text etc..
Unfortunately the sad truth is that any smart phone under heavy use will have the battery drained under heavy use. I for one rarely leave my phone off the charger when one is available, be it in my house, work, or in my car. Like water in the desert you never know when your next charge might come. I would suggest investing in a car charger for you trips through the city. Not only will you not have to worry about battery drain while listening to music, but when you arrive at your destination you will have a nice and fully charged phone on what you can impress people with. Car chargers are rather inexpensive if you check on ebay. I got a wall charge, car charger, screen protectors and a tpu case for less then 5 bucks shipped. While the quality might not be as good as the sprint charger(with what seams like a 20 foot cable) it will get you by just fine.
Sorry I wasn't clear enough guys!!!
What I meant by battery drainage was in the LONG HAUL, will recharging it over and over again damage it...as I understand it, most cell phone batteries have 1000 charges life span.
I do have a car charger that I rarely use unless I have to. Will leaving my phone connected to it WHILE using being harmful? I think thats my biggest question here..I have heard that using the phone while charging can spell bad news for your phone.

Honestly I've heard stories of this happening to people, but it has just never happened to me. The batteries on all of my phones have had pretty consistent loss over time so I personally don't think you have anything to worry about.
I haven't noticed any significant loss in battery over time other than what naturally happens to all batteries whether you use them heavily or not. I'm always on my phone, streaming music surfing the Internet, using a car dock to recharge and it seems just fine still after having this phone since day 1 that it came out.
I couldn't tell you the best setup since right now I'm just running stock rooted sorry.

And you can get a new oem battery off amazon/ebay for like $15. I've noticed some batteries lose their charge more then others but to me it always makes more sense to just keep it charged then buy a new battery later if I need to. I'm talking over a year for me before I can tell a battery gets worn out...

I can say from my previous phone that over time if your a heavy user and you find yourself always searching for a charger while your on the go, your battery life will diminish and eventually the battery will swell.
My last phone a Zio from cricket, began with a battery that would last about 7-8 hours with me using it to text, listen to pandora for an hour on my way to work, check Facebook, XDA, etc...
After a while I had to charge my phone more often, eventually the battery could not last any longer than 2 hours 3 if I didn't use pandora.

Yeah. All lithium-ion batteries will eventually lose their vitality. It's just the nature of the battery. Constant use will definitely make this happen sooner but not soon enough to be a fear in the back of your mind. I actually need to replace my laptop battery soon because of this but it would happen sooner or later...
I find that after a few days in my phone, that my battery starts to drop faster, so i just swap it out for my spare and drop the spare in the phone. But usually between 2 days i will swap at least once.
The external charger always charges to 100% where the phone a we all know is flaky at best in charging.

the last thing in the world I would worry about is wearing out the phone or battery..
I'd be more concerned about a meteor hitting me, or winning the lottery!
luckily, this isn't an iphone or a razr, so if the battery goes to ****, you can just buy a new one. if I were you, i wouldn't think about it again. pandora away.
One thing I did was if I am going to have it plugged into the charger and using it heavily I bought a cheap knockoff battery that I just throw in for this purpose only. Heat is one of the biggest killers of batteries and if you are using your phone heavily while being plugged in it gets very hot. I figure if I am going to kill a battery it may as well be a cheap knockoff one then the actual OEM one.

I got the Motorola rapid car charger for my entire family. We all use the E4GT. Super cheap, $5 on Amazon (free ship with prime), charges at 950mA so it's every bit as quick as Samsung OEM, and it looks quite snazzy with the blue led window. Definitely top tier quality!

I recommend using a profile locked at 500 or 800 max to get max battery life. Did this on a trip recently, 10 hour drive. Pandora or doubletwist and gps the whole way, no battery drop with screen on and charger plugged in.

No problem! Also, if you want a solar powered backup, checkout Solio
I read some stuff on solar power chargers. I'm not so convinced about their actual recharging power. I'll go for external power pack for now.
Thanks for the replies. I'll repost here with details as to the performance of the battery pack I ordered....a Mili as kindly suggested above.

I had your same problem because of my traveling. I tried solar chargers and you can just use 'em to leave 'em home. I bought two batteries and car chargers (even the original Note ones - wich needs almost 1000mAh), then I bought the TurboCharger Proporta 7000mAh external battery. It rocks I charged my Note from 15% to 95% (power on) in 2hr 30mins. The TurboCharger fully charged an iPad 2, a Nexus S and a BlackBerry 9800 before die

how about those ebay single AA cell chargers? Are they any good for the note, or do we need a certain voltage or amperage minimum to charge?
Your biggest issue is going to be charging your Asus Transformer due to the fact it requires a higher voltage and USB 3.0 for charging.
Have a look at this topic on solar chargers for the TF.
Trying to reduce clutter and use less outlets on my desk at home, I have a GT 10.1 and the E4GT and was wondering if it was safe to use the brick from the 10.1 with my micro usb charging cable for the E4GT.
I know they have different amps, the GT is rated higher, so it should charge the E4GT faster. Just not sure if this is safe.
I know for Blackberry's you can buy the rapid playbook charger and use it on the phones for a faster charge. Now that I think about it, I have used that Playbook quick charger with my E4GT. It works fine but I just hope I am not damaging my battery.
Thanks

Well, you can charge it faster but i will over time reduce the battery life. coming from an electrical back round, The best thing for the battery is bring it up on a slow charge. Lessens the chance of burning/shorting out a cell. L-Ion batteries are great for not having a memory like Ni-Cad or Ni-MH. So i frequently throw my phone on the stock charger a few times thru out the day. I would recommend you stick with your stock charger as it was ment for that battery. hope this helps.

Thanks, I did not realize that a fast charge can harm the lithium batteries. On a side note, lithium batteries can only be charged a certain amount of times correct? So if you charge your battery say four times a day, you have used up four charge times/cycles?
Thanks
A sprint tech told me that our phones have a built-in safety, and will not engage in charging the battery or damage it in any way if the amperage is incompatible on the charger.
Beware: this information came from a sprint rep over the phone, and I wouldn't even begin to know how to verify it.
Yes they are limited to certain amount of times they can be charged. I'd have to look it up again why tho.

No need to look up the reason, just wanted to make sure that I was correct in thinking that. I try to charge my phone only once per day and at night, if I have to charge it up during the day I will but I try not to keep pulling it on and off of the charger.
Thanks
OK. Yeah there are a lot of tweaks out there. Like if u use voltage control, use agat or sleshepic's TW ICS kernels and under volt and use conservative govener. Really helps battery life. Also depends how you use it

After a year I would like to power my battery with ad external help.
Does external batteries work well for that?
There are better brand to choose?
There are particular skill to search for?
I would like to use it with several devices
I've been using various Anker products with great success and no issues so far (just search at Amazon, I can't post external links yet). The reviews are also quite positive and the price tag seems fair.
/e: ok, there's already a thread on that topic.
For me, external batteries are a must. I have 2 (cheap ones from ebay) and although they don't have any extreme features, they give me some little extra power to get through the day.

external battery
If you need to charge several device at the same time, I suggest you buy the one which have several outputs. And you must notice the Output current because different device need different current, for example,1A can charge all of the mobile phone but can't charge your ipad, if you need charge ipad, you should choose 1.5A or 2.0A. That is to say, if you need charge ipad and iphone at the same time, you need buy the battery which has two outputs 2.0 and 1.0.
As for the brand, choose the ones who have passed MFI certification will be better, but the price will be much higher, So I think brand is not very important, the most important is the quality and price. Hope it is helpful for you.
If your devices don't make it to the end of the day and the battery is still acceptably new, you should go for an external battery.
But, before buying one, you should really consider whether you're wasting your battery: do you keep your internet connection active all the time? Do you use WiFi when possible? Do you switch to Airplane mode when you are somewhere with little to no signal? Is your GPS/Bluetooth/NFC activated even when you're not using them?
There's a lot of small things that may help you make it through the day without an external battery

Hi, my opinion is that no external battery, but more internal capacity if. I have the 9300 mah zerolemon for note 2 and it's going very well, although a little heavy, but worth it. Regards
