When should I wipe the battery stats

I just got my new 2150 mAh battery in today. Phone is off right now, with the new battery in it charging. Now I wiped the battery stats before I threw the new battery in, but should I do it again after the new battery has a full charge and I turn it on for the first time???
There has been a lot of vapor regarding battery stats. I have seen it claimed that stats (which to my mind only report things that have happened) can influence future battery performance.
That makes no sense to me whatsoever.
I do it with every install, just to do it, dont know what effect it has, but i never have issues with roms or kernels. Just my $.02.

The most widespread theory is you should first charge it all the way up, bump charge it once more, then clear the battery stats. You should then proceed to let the battery drain all the way down to 0, and when you recharge the software should charge the battery to a fuller amount.
Of course I don't know how much truth that actually has. I know when I did that, the next day wasn't great, but everyday after that for the next few days got marginally better (less of a drop in the morning).
As far as i understand it (i'm not an expert, just read a LOT of threads) wiping the battery stats won't have any effect on how well the battery charges - it just helps the phone report an accurate percentage as the battery discharges

[Q] Verizon Nexus Battery percentage going up?

I have been noticing something strange. I have gotten in the habit of draining my battery down to single digits before charging in an attempt to keep my battery life up. I usually use netflix on 4g to do this as it does a pretty good job of sucking the juice down quickly.
A few times I have noticed that after I shutdown netflix and let the phone sit a little while that the percentage actually goes back up. For example, I kill netflix at 4% battery left. I set the phone down for a bit and when I pick it back up the battery is at 10%. I have seen this multiple times.
Just curious if anyone else has noticed this and anyone has an explanation for why this happens.
I believe it has to do with the battery meter displaying how much battery you have left based on what you are doing? So when you stopped being resource intensive it adjusted itself.
That's one explanation I have heard.. there is also one that has to do with the amount of current going to the battery.

I can't answer your question directly as there could be multiple reasons. (Battery capacity estimation is tricky business, and I don't know what algorithm they're using.)
But I can tell you that the common belief that one ought to discharge batteries before recharging them is not applicable to modern lithium batteries.
I was (to some extent) true for old-fashioned NiCd cells, but modern Li-ion cells shouldn't be excessively discharged. If you want to prolong battery life it's more important to keep the battery cool. (Lithium cells degrade much faster at elevated temperatures.)
(To contradict myself I have to add that the battery capacity calculation can be improved by discharging the battery completely from time to time - but again, this depends on the battery capacity calculation algorithm they're using.)
I understand the way current battery tech works. The discharge is not for the battery itself. Its for the Android OS. I have noticed that whenever I plug my phone in in the middle of the day, the next day my battery doesn't last as long. In fact the poor battery life will remain an issue for about a week until it levels itself back out. I have noticed this behavior on multiple phones by multiple manufacturers.
You end up going in a circle. You use heavy data one day and as a result you have to plug in in the middle of the day. The next day your battery doesn't last as long so you plug in again. Unless you allow your phone enough time to level back out then it will always appear that your battery life is aweful. Since i've been discharging my battery I am able to unplug my phone at 7:30 am, use it moderately all day with GPS, Bluetooth, 4G on/wifi off with a live wallpaper running. At 11:30pm when its time for bed I still have around 60-70% battery remaining. I find myself having to watch a few hours of netflix on 4g in order to drain the battery so I can plug it in.
I'm not sure if this behavior is a result of an issue with the battery stats file or what but I do know that when I flash a new ROM it appears my battery life is reset to how it was before I had shortened it by plugging in the middle of the day.
many of us have seen the percent rise slightly, its normal. when under heavy load watching videos or something and then you are finished, the voltage gets relaxed and pops up some. since this phone uses some type of voltage calculation to determine percent, it will jump up once in a rare while, typically right after you placed it under heavy load then went to idle.
it's normal..

Another Battery Question

So I have been experimenting with when and how long to charge batteries, and I'm confused as to how Li-Ion batteries function.
I have 2 standard batteries, 1 extended battery, and the cradle charger. From I've read and heard,, is that its pretty much impossible to get the best of both worlds, by that I am meaning good battery life, and the life of the battery.
From what I have read, it seems like that to make batteries last longer, charging them before they shut the phone down is the best option. Also, that charging the phone while it is on is bad, causing the battery to have a "parasite load" which screws up the charge.
And from what I am seeing, this is relatively true. In completely running down the battery to the point it turns off the phone and then recharging it gives it a better life when the phone is on, but I believe that the life of the battery will not last as long.

This is where I got most of the info.
Can anyone who knows batteries well confirm or bust anything I have said?

[Q] what do you think about the battery life of cleanromace?

Well it has been draining quite fast and I thought it has a good battery life my screen is the one taking up the battery life and I have very little app
Can you tell me about your phone's batterylife with cleanromace?

Phone shutdown at 4% left

Seem like the battery deceased so fast after 2months of usage.
7+ hrs usage... Still alright...

Is this the first time it happened or this is what's happening all the time now. If it's first time then the system could've read wrong voltage/charge. But if it's constantly happening then I'd say something is wrong. If you want I'd say call up Samsung or your carrier and have them send you a different unit if you don't feel comfortable.
Mine was doing this at 3% for awhile and suddenly it's back to shutting down to 1%
You should be more concerned about leting your device reaching that low on battery, it is very bad for batteries to almost completely discharge, that is really, really worrisome, if for any reason your usage is that demanding and you can not plug your device to an electrical outlet, get a powerbank or a battery case

I second this. Folks don't understand just how bad discharging their batteries is for the battery longevity. This is why you see so many folks that kill their batteries in 2-3 years. Even a 3 year old battery will still retain a good amount of its original capacity if you do not expose it to full drain and recharge cycles. Top up and top up frequently. This is the best way to ensure a long battery life.
Pretty sure the battery has a system built in to monitor and manage real full depletion.
It probably doesn't deplete to the point of damage.
As far as what percentage it dies on, I mean that percentage is just an algorithm to estimate battery life. It's probably not very precise especially when a percentage is the value output.
I try not to let mine drop below 20% and charge to 80%
