You've probably heard about this before, its simple:
1. Charge your phone to 100%!!
2. Boot into recovery
3. Scroll to Advanced > wipe battery stats
And there you go!! I'm running xboarders quicksense 1.5.1 and now it has tremendous battery life.
I originally saw this method in mikes android revolution Rom post so thanks to him!

I've read alot and tried many methods in the past, and one thing I am conviced is that you don't really have to drain your battery completely before cycling. The dev of 'Battery Doctor' app says you need to go below 20%. I can acheive pretty much the same effect if I start from just below 50%.
The key is to keep the charger plugged in after you get the green light. 20min is probablly right, although I tend to keep it longer because I usually go to sleep when I cycle batteries.
over charging lithium ions is not a good idea...also you do not need to cycle lithium ion batteries as they contain no memory as the old ni-metal hydrdie and ni-cd. batteries..
.infact is is advised to charge you batter often and keep electrons moving in your lith ion battery as oposed to ni-cd which is better to let it fully charge and fully discharge.
Do not over charge or fully discharge a lithium ion battery...infact the high voltage stresses the battery further and shortens its life. also do not discharge you battery fully as this is also not good for it...with lithium ions it is good to charge as often as possible, to prevent erosion inside the battery...while doing this you must not use the device...so even if you charge it for 10 minutes its a good thing for the battery. do not use the phone while charging as this confuses the battery.
here's a good article, that explains everything completely http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
From what I have read so far, wiping battery stats simply erases the information in the battery usage screen. I don't see it having any benefits to how long the battery lasts even in my previous attempts to increase battery life.

While I believe the information you posted is true, I think it may mislead some people here.
1. when you wipe the battery stats, you still need to do the cycling. Otherwise, your new stats will be off.
2. 'plugged in' doesn't mean 'constantly charging'. The IC chip on our phone is supposed to do what you are recommending we should do; charge to close to full, drain some, then charge to close to full. I say 'supposed to' because I only read about it somewhere.

You're righ that wiping battery stats won't improve your battery hardware-wise. But if done properly, wiping stats and cycling should re-align your phone's knowledge of the real battery capacity. If you have 100% at one time and 50% just an hour later, you know either your battery is bad, or your stats is off.

A properly designed battery charger (like the one in the phone) will not overcharge the battery. These chargers have circuitry to prevent overheat, and as the phone gets close to maximum charge, they slow down and then stop the current flow. They don't want exploding batteries!
EDIT: I do worry, however, that the phone is designed for the stock battery at 1.8v, and might overcharge a replacement battery (mine are all 3.7v). I have read of some people that had overheated aftermarket batteries when charged in the phone. I use my external charger for the spare batteries.

You don't need CWM recovery. You don't really have to be rooted, either. If you know how to temp-root, you can wipe the battery stats using adb shell or terminal emulator.
The file is located at /data/system/batterystats.bin. You can remove it by:
Code:
adb shell
rm /data/system/batterystats.bin
Don't forget to 'su' if you're using terminal emulator.
In my experience, the best time to wipe the file is right before starting to charge the phone all the way to full.
So, has anyone tried this lately with success? I'm a complete noob and have no idea about rooting, but might look into it if this really works for the Li batteries.

This was common on my droid x for so long while flashing but is it a good form of practice on the Rezound? The reason I am asking is I flashed Bamfs Cubed rom and my charging led goes from orange to green at 98%, never making it to 100. Would it be wise to go ahead and wipe battery stats and see if it fixes it? I presume there would be no harm to the system or battery in doing this.

Don't agree. Just like I don't agree with people saying task killers are bad. I guess with the way I use my phone I get different results. I have always noticed better battery life wiping battery stats. Now it could be that the OS will fix battery stats itself over time, but when you ate bouncing around a different rom every two days then the OS doesn't really get a better feel for the battery.
Plus...I came from the evo 4G where we uses trickle charge kernels and I want those back. Never had better battery life than when I had those. Was doing 35+ hours a charge on the stock battery.

Haven't bothered since I never could get the thunderbolt devs to try it. There was "reported" cases with no proof that it caused some batteries to go bad. Even then they were cheap Chinese batteries that 2 people total I think it was claimed went bad.
It was always nice to pull your phone off the charger in the morning at 100% instead of it showing 100% and you pulling it off the charger to say 92%.

Well there is the fact that Li-Ion batteries can not be trickle charged after reaching full charge...
Well they can, but it will hurt the battery. And that isn't me talking from a few bad battery posts... but from knowing how Li-ion batteries work and charge... and reading engineering papers about Li-Ion batteries.
Luckily trickle charging is slow and most people only leave the battery on the charger over night at most. Plus they charge while the device is running and using power. Should someone leave the charger going for 24 hours, with the device off, we would probably be hearing about a fire.
What is probably happening with these trickle charge kernels is:
The phone is going to use some power at all times, the trickle charge is probably just enough to keep the phone running and preventing the battery from draining slowly.
This works because there are two ways to handle full charge status while the charger is still connected.
1) When the battery reaches full charge, the battery is isolated from the device preventing the device from draining the battery. The device then runs solely off the power coming in from the charger. (this method would not benefit from trickle charging, and forcing the battery to continue charging will at best slowly hurt the battery over time, and at worst cause a fire/explosion)
2) When the battery reaches full charge, the charger is isolated from the device. The device runs off the battery until the charge drops to a certain level (usually around 90% or so) before charging starts again.
The second way is how the Rezound does it, and most other devices as well.
The first way requires the ability to switch instantly to the battery from external power without any drop in voltage. This is difficult to do, as a drop in voltage could cause the device to crash/freeze, so many devices do not use this method.

Well if the device was off then the kernel wouldn't be running and trickle charging the battery but when turned on and the battery fully charged they would very slowly charge the battery as it dies. So there should be no risk of the battery catching fire. And anyway, the way the evo trickle charges worked is they would charge your battery to a certain voltage. Once it hit that voltage it would stop charging until it dropped. So it wouldn't be hard to protect the battery.
Did this for 6 months on the evo with no issues.

some of you maybe remember my thread about how long your battery life holds because mine ends very fast.
well i searched over the internet to find how to increase my battery life and i fonund a way that lot of people said that this way increased there battery life.
here is what you need to do:
charge your battery to 100%
go recovery mode: ADVANCED- WIPER BATTERY STATS
unplug the device from the charger
and select yes.
than dont charge the battery let the battery go to 0% and than charge it again to 100% and spend the battery life again without charge it.
do it 4-5 times and than your battery life should be a lot bigger.
im on second round.
if you do it please tell here.
and if you see that the battery life become a lot bigger tell this here too.
is it better to wipe the stats before or after you unplug your charger? Does it matter?

Yes, and in addition, our device's method of measuring battery state of charge is so rudimentary that any other "calibration" method you might apply is pure placebo.
No Samsung Galaxy S or S II device requires any sort of battery calibration as the fuel gauge is self-calibrating over time. In the Players, the battery charge level is directly derived from the current voltage with no historical information playing a part.
from my experience there is no need to do that wipe just "Calibrate" by draining the battery to its autoshutoff point and recharging completely at least once a month. personally I do it everytime with my 4.0 player just like I did with my env touch and that 2.5+ year old touch would last like 5 days of light use.

,this is how i calibrate my battery,before i have 45min of standby it will decrease from 100% to 99% but now it is 2hours & 34min before it go from 100% to 99%,i felt the drain after 2 weeks of overusing my phone (1week playing paladog and 1 week flashing different roms,kernels and theming my phone with different launchers),
- Charge your phone to 100% while it’s on.
- Unplug it from the charger, power off, then charge for 15 minutes with it in a powered off state.
- Unplug charger from phone. Power it on, and then charge 15 minutes while the phone is on.
- Calibrate battery using battery calibration by NéMa then unplug charger reboot.
- Power on, charge for 15 minutes then unplug.
- Finished.
note: deleting battery stats(calibrating) don't increase your batterylife said by others and it is just a placeboo and i believe in them,but it fix my battery drain so why don't we give it a try,there is nothing to lose,battery drain is so annoying.

That was from LEWA OS, one of the best rom at that time...:good:
First and foremost, a Google engineer debunked the idea that batterystats.bin has anything to do with how the phone charges. By deleting it, you're actually inconveniencing yourself, as there will be a short period in which you won't have accurate stats.
Secondly, the O1 has a lithium ion battery. Lithium ion and lithium polymer batteries don't need to be calibrated, as they have no "memory" effect (you can read more on that here).
Moreover, these batteries have built in charge circuits that protect and regulate the battery. Ever wonder how the phone knows the battery temperature? It's pulling it off the charge circuit. That same circuit also prevents the battery from ever being overcharged or discharged fully, which is why that convoluted guide about calibrating your battery by draining it to "empty" and then recharging it to full doesn't work. Worse yet, intentionally draining your battery is actually counter-intuitive, as lithium-based cells wear more as their percentage of discharge increases (you'd be hurting the battery in your effort to calibrate it).
Your instructions aren't detrimental, so if it works for you, go for it. However, based on my understanding of these batteries, it seems to me that this procedure is inconsequential.
Besides, a new battery for the O1 is only $6 USD on Amazon or Ebay.
I recently purchased the Anker battery for my Amaze. I've done the suggested 4 full battery drains and charge, but I've noticed something odd. Right after taking my phone off the charger, the % drops pretty rapidly, roughly 10% in about 30 min, with almost no usage. The level continues to drop pretty rapidly till the % gets down to about 70%, where it seems to stabilize, and drop at a slower rate. Anyone else seen this issue, or know what might be causing it?
Sent from my HTC_Amaze_4G using xda app-developers app
Mine does it too. But it stabilizes around 80% and I can get a good 16hrs with moderate-high usage and about 3hrs screen time. I was reading somewhere that this is a common issue with Anker Batteries.

This isn't a problem with your specific battery, it has to with overcharge prevention.
Essentially, once your battery is fully charged and the LED on your phone flashes green, the phone's battery is no longer charging, and it is actually running on stand-by off of the battery. Perpetually trickle charging the battery would shorten the life of it.
As a result, the battery consumes some energy while the device is in stand-by, but until the device reaches 80% or so, it doesn't start to re-charge. Because it is still plugged in, the device is reporting a full battery, even if it has been running on stand-by for hours on that charge.
There are kernel modifications that can change this, but unless it's an issue for you, I would avoid doing so for the long term preservation of your battery.

I have two Anker batteries, bought at the same time. Both were conditions per instructions. One of them has great battery time, the other has very poor battery time. I think it is hit or miss with these batteries.
If you're interested, I think you'd be able to get that stabilization (after then initial drop) a little higher if you tried calibrating as per here. I'm at about 90 for the one I calibrated, 80 for the other.

The batteries in our phones (and most newer electronics) are Lithium-Ion (and in some newer phones Lithium-Polymer). these batteries have no 'memory'. in fact discharging them all the way is very bad for them, and can actually cause the battery to rupture if its done too extreme (you would have to short the terminals for this to happen)
The reality of this is that the less you let your battery discharge, the longer it will last. Every time you let it drain all the way (or almost all the way) you are harming it and reducing its lifetime.
The best way to take care of your phone's battery is to try to keep it between 50% and 80% full. Even keeping the battery fully charged for very long periods of time can be just as bad as discharging it fully.

The "cycles" which supposedly prolong our battery life are not true. This used to be the case, but like TopDroid said, with lithium batteries they do nothing.
Its like how on older versions of Android, task killers were useful, but newer versions don't need them and is actually bad. With batteries, the technology has progressed from that time.

Which of these two ways is better?
1. Use your phone to 20%~10% of battery and charge it till fully charged.
2.Frequently use and frequently charge(charge from 60% and unplugged at about 80%, then use to 50%~60% and charge again)
Which is better for the battery's life of phones and tablets,1 or 2?

I prefer 5%-15% because it gives more accurate battery stats + if you use go power master it would say "Healthy Charging"
or Method 1 as well
