[Q] Batteries - Epic 4G Q&A, Help & Troubleshooting

I have for my Epic the standard battery, along with x2 3500 mAh battery replacements. I've noticed that sometimes, mostly at random, the battery drains fast; on all batteries. My questions are:
1) Should I reset battery stats whenever I use a different battery?
2) Should I just use 1 battery and leave the others for emergency use? (I ask because I'm not sure if switching batteries is the problem)
I notice that sometimes the bigger and better batteries last as much as the standard one. I don't find myself needing the 3500 mAh a lot, but I would like it to last more than the normal one.

Yes u should always clear the battery stats when switching batteries. I change all the time and don't have any problems.

[Q] Extended Battery w/ From eBay. Suggest Sellers? [First Time Post]

XDA Members,
This is my first post, and the HTC Evo is my first true Android device (late, I know, but I tried the Cliq and... eh...)
We all know that the battery for the Evo isn't enough. I'm on eBay examining my options, and noticed that there are extended batteries sold in the US that all pretty much look the same.
Are there any particular sellers that you would recommend? I know what ultimately matters is the brand and what the label says but I figured that this forum chock full of experienced Android enthusiasts would have certain people they'd recommend for certain products.
If not eBay, I have a couple of cheaper batteries available on Amazon.
Thanks!
the best performing battery is the stock oem htc battery, unless you want to use an extended battery door and make the evo look like a whale. then get the official sprint extended battery, it's about 50 bux. I get about 30 hours on my stock battery thanks to the great kernels and roms on this forum.

Mugen seems like it keeps a lot of people happy. I'm stock though
I just got 2 Galilo with charger and they seem to be as good as the stock ones.
I went the cheap route for and extended battery and I got EXACTLY what I paid for, a CHEAP battery.....lol
Now i have to man up and take the loss on all the CHEAP accessories I brought for me and my wifes EVO and drop big $ on Seidio...
My advice do it right the 1st time....
What kernals and roms are u using to get 30 hours? I'm lucky if i get 8
Sent from my PC36100 using XDA App
How are you guys getting so many hours? I only get like 8 Hours on my heavy use and i bought a 3500mah extended battery wtf? I'm also using the net Netarchy sbc 3.2 more havs and mym rom with setcpu running profiles. What am I doing wrong? I even have juice defender running aswell.
well my guess is hes using Myn's Warm RLS5.
as for the kernel. probably found a kernel that helps with the battery life more than the performance.

How do i spot fake OEM batteries?

There are a lot of batteries out now claiming to be OEM batteries for the Evo. They are red like the original. But saw somewhere that sellers were takeing the aftermarket black batteries and just making them red. Are there any ways to tell if it really is a OEM battery? Besides the obvious, buying it from sprint or htc. And if you know of a place to buy them on the cheap let me know plz. thx.
price
No clue what an oem battery costs. I'm using the chicitec from amazon 2 for 28.99. Good deal,better life. Will post my comarisons in that thread tonight.
I heard checking the back of the battery will tell you the mAh and reveal if the battery is real or a fake. Not too familiar with batteries but that's what I read. (lift up the sticker covering the battery)

A REALLY EASY TEST and it works everytime... first suck on someones stick. Then put the battery in your mouth. If you die then it is real. if you don't. it's fake. lmao.

How old are you? Really?
guess that how he did it
I bought a set of two batteries for $10 on ebay. They were 2000 ahm while the original htc battery are 1500ahm. the problem was that the ones I got were lithium ion. Make sure you get lithium polymer. It makes a HUGE diff. The twp together last but its a pain halting out the one fort the other. Not to mention changing them.

Go to sprint chat. Tell the rep nicely your battery life sucks. He or she has been instructed to handle your issue by giving you credit for a new battery. Go to Sprint store. Purchase extended battery or regular battery. Go home and back on chat. Tell the new rep you were told you would be credited. He or she will do it. Next month see it on your bill.
To ensure 100% oem get it from Sprint. Plus the method I mentioned is free

[Q][discussion]Cool software features of GS3 ported to our Nexi

A couple of things that I would like to see on custom ROMS
SVoice. First of all I really don't care about SVoice. But I find pretty cool that when alarm rings you can just say "snooze" instead of wondering in the dark where is your phone.
Eye tracking to keep screen on
Direct call
Auto tagging of photos
Is this possible for the ROM developers? I mean the hardware is there, right?

There are a few random threads about some of these features. Basically if what I read in them are correct we will need a port of the new TouchWiz. And it hasn't been released yet so its not available to port.
Eye tracking is going to be such a battery drain, LOL.

Thank you so much, I read through Flipboard pretty much every day, lol! TMOB had better be in on both of these whenever they are readily available or I'll leave them! Of the two, I am most exited about the battery tech. Battery technology has been lagging while everything else has improved by leaps and bounds. I'm already in awe of the developers and development that happens here as well as researchers from MIT and anywhere else!

I hope tmobiles on board too! The article about the bandwidth tech mentioned that there were already a few companies signed on, so I'm hoping!
I would guess that since both are MIT related (one said it was an offshoot from MIT) that anyone in on one, could easily be at least looking into the other.
Though now that I'm thinking about it, the life doubling tech would more likely be picked up by manufacturers than the carriers. Lets just hope Sammy goes after it! (And pray that apple doesn't decide to steal....I mean patent it themselves!)
(No id rather not get into that discussion! There's a thread for that! Just a quick jab is all! )
As for battery tech, who knows what they're up to. At this point id just like to see more widespread use of the LiPo (Lithium-Polymer) batteries. As far as Im aware they've sorted out most of the problems and they are superior to Li-Ion batteries in every way! Some smartphones already ship with them, but last I looked they were a pretty rare thing for replacements.

Lol, funny! Just read the other day they had to post another apology in Europe because it was a non-apology, then they were slapped with another order to post it again in a larger font, so what they did was use some Javascript that only rendered the main portion of the page no matter what resolution you were using meaning anyone had to scroll down to see the apology. They are looking really bad lately and it's sad.

Never heard of Lithium-Polymer batteries, I'm going to google it as soon as I get my phone reconfigured. I just flashed Wicked V7 today.
One of the things that makes em really cool is they are shapeable...if that's even a word! So rather than being constrained to a certain shape cell you could theoretically have something like the case itself be the battery. They are also supposed to have longer life both in number if cycles and runtime between cycles. Initially they were kind if unstable and could lead to leaks or even fire or explosion. I think I've heard that a lot of the issues have been solved though.
They can be smaller, lighter, stronger, and the fact they can be made to just about any shape means it could open a whole new area if design for all sorts of stuff!
I'm going off memory on all of this so if I got something wrong I apologize, byt I'm oretty sure I'm remembering pretty accurately.

"more than 65 percent of its energy"
The "its" part of that sentence is referring to the single or multiple chips themselves, not the entire phone. So, this will increase the efficiency of that particular chip and only while in standby mode. I don't see how this would increase the phones battery life by 50% since cell standby is always very low on the list of things that consume my battery. Unless you count when I leave it unplugged and go to bed, for those 6 hours cell standby is top of the list. But, how often do we do that, and do we care about how long we can leave is unused? I think this will help save the broadcast stations some decent power, but as far as our battery life goes, I think its a lot of hype for nothing.
Let's say these chips do increase the efficiency from say 35% to 100%. Also, lets say cell standby uses 10% of your battery. I'm pretty sure mine is often less than that, but I will start recording this # more closely. That translates to an overall power consumption change of 6.5%... worth doing, but not worth phone users getting excited about.
I should also point out that the new chips cannot possibly increase efficiency to 100%, and I did not take into account the power use of the newly added chip because I have no idea how much power it will consume. Both of those things will cause the 6.5% to decrease, but without more detailed information on the chip I cannot even speculate as to how much.

...and the only way to make it more efficient is by reducing the power used in standby. However, signals can be distorted if moving from a low standby mode to high power, so current technologies keep standby levels fairly high. That wastes electricity and is partly what causes smartphone owners to recharge their devices multiple times a day.

It seems to me this sentence refers to existing technology-the current state of affairs, not to this new discovery. We'll just have to wait and see.
This is just a little bit off topic for Android.....But it is just too cool not to share!

For your second question, i dont think there are any extended batteries strictly from Sprint or Samsung. But if you take a look at the Accessories forum, theres a review on a third-party battery called ZeroLemon thats 7000 mAh
That's correct. I don't know of any extended batteries that still have nfc capabilities, and that's the number 1 reason a lot of people don't go for the extended battery route.

1- Battery life is good on the S3 but sometimes settings and apps need to be tweaked. Many threads on this.
2- Yes, go to sprint.com and select shop then accessories. Select the phone and it's listed under Charge & Power. Or go to amazon and get the gorilla gadget extended batt for less then 1/2 cost of Sprint. I personally don't have an extended batt but thought about it, and recently did some research on em. Both options keep nfc fully functional.
3- Easiest method to root MB1: http://forum.xda-developers.com/showthread.php?t=2011491
