Accessories Extended Battery question- calibrating?

Hey guys,

Just a quick question about the extended batteries you can order for the Evo (the 3500 mah one with a special door to fit it)

I ordered one on amazon the other day, and it showed up today, its not the seidio(sp?) one, or the one sprint sells , but its essentially the same deal, the door just looks a bit less obnoxious . Anyway, It didn't come with ANY instructions, other than something on the battery saying to read the instructions before using the battery....

I've heard lithium ion battteries don't have a memory, but is there any conditioning I need to do on this thing? I've had it in my phone for a while now because I read somewhere that you're supposed to run it dead, then charge it fully without using it (so I was trying to do that tonight, but the power has only gone down 10% in the past few hours with 4g, wifi, bluetooth, and a youtube video playing for 15 minutes or so
 
You shouldn't have to do any 'calibrating' with your battery. Lithium Ion batteries do not require calibrating nor do they have a memory of sorts (as opposed to Nickle Metal Hydride [NiMH] batteries).


Some people will argue that draining your Evo battery completely and then proceeding to charge to 100% yields better results over simply charging as you go... be it a placebo or not.

Sounds good. Just read that writeup , good stuff
 
Just charge and go. Takes 3-4 hours to fully charge but draining isn't necessary or good. You won't condition the batteryas cells don't expand or contract.
 
I just got my Sprint extended battery tonight. I would have gone for the other better options if it hadn't been for the cost reduction (Thank you Sprint for the account credit).

My plan is to charge it fully with the phone off overnight (8+ Hours recommended) to get a really nice complete charge on it. Then on my first use, run it all the way down till it shuts itself down, then charge it fully again for 8+ hours with the phone off. This was the process I've read before and the one that I followed with my stock battery. I had really amazing battery results with it for the first few months I had my Evo running bare bones.

Generally when they ship a new battery with a device it comes with a quick and partial charge on it (so the power cell doesn't discharge during shipping). I believe it is probably best for the battery to give it a really good long cycle charging to begin with, then discharge and recharge it again fully. I'm also going to make sure to unplug it and plug it back in a few times after the LED goes green to make sure it is completely topped off and fully realized by the system.

Hopefully that will give me a great foundation to last me another 6 months. My goal is to just have this battery last at least a day without dying after my daily light to moderate use (I follow all battery saving conventions, but still come up short at 6-8PM with my stock battery).

My plans are not necessary and un-proven, It is just what I do and what I feel is the best process. I have no supporting evidence other than my own personal experience and anecdote.

Pyro,

What you're doing is essentially resetting the battery level indicator which is giving you a more accurate account than anything else. Nothing wrong with it at all and in fact you're getting full use out of the battery.

As it has been stated many times you can't condition an Li battery at all but fully charging and discharging isn't harmful for the battery at all. The internal protection circuit in the battery won't allow a discharge below a certain level or inversely, charging above a certain level.

Yes, I understand what I was doing and why I was doing it. I also understand the technology behind the batteries. I never claimed I was conditioning my battery. I was just explaining my process in dealing with a new battery. People can tell me there is no point, but I'm still going to follow that process since it is what I do and I see significant value in it.

After my initial charge I got 40 hours of uptime and 8 hours awake time, and that was on an inordinate day where I went downtown for a concert. Which means I used Navigation (used 30% of the battery ), 4G Data, and GPS for significant lengths of time, plus Camera and Camcorder alot. I'm pretty satisfied with this battery. I'd recommend it to anyone that can handle the extra bulk and get a discount off the cost (not necessarily worth it for full price when there is more MaH for your money elsewhere on the net).
 
Hey, was just wondering..... alot of people are talking about how they let their phone charge for 3 to 4 hours on the 3500ma battery to get a full charge! I use an app off the market that uses "Full Cycle Charging" and my phone charges from %10 to %100 in about 1hr 40 minutes!! Does it really keep charging after the light turns green? I have two of those 3500ma batteries off of ebay and they worked awesome for the first month and now neither one of them last much longer than the stock battery... They were made from Japan and the Seidio brand battery says they are made from Japan, so are they any better? And why is my battery reading %100 in just over 1 and a half hours?? Do I have to unplug it every few minutes after it turns green to try and squeeze out more of a charge?? Thanks in advance!!
