I've seen too much conflicting stuff on this. I know it's necessary for some who flash roms but for regular phone usage, is it recommended to discharge the battery completely and then re-charge every few months for li-ion or will this do more harm than good?

Your device will keep you from completely discharging your battery. Your battery is rated for a certain number of recharge cycles, 1 cycle is from what the device calls 0% to 100%. If you recharge from 50% to 100% that counts as 1/2 a cycle.
One of the most important things you can do it to keep your battery from over heating. Heat will make it degrade faster and you will lose recharge cycles.

Hey i flashed my device with the battery at around 80%.
after the flash it was 100%...
so this means i just lost 20% of my capacity? how do i fix this?

I don't believe you have lost capacity. It's only your gauge that's slightly altered. If you recharge your device fully(and about an extra 30min) you should have the regular capacity
How could going from 80% to 100% equate to a lost ???
it's posible that you'd gained the extra charges while the flashing process was going on ( because it was plugged in ?? ) ... if it wasn't ... no idea why

If i understand the post correctly they are equating am 80% to 100% a loss for 2 reasons:
1. because he would have lost charge while flashing due to the massive battery drain.
2. because now he is stating that his 100% is really only 80%
but i would probably just leave it charge overnight and you should be fine, the gauge just sounds to be off, it shouldnt be a true loss (unless the battery is bad)
Is there any other way to sync the battery with the device? I been trying a full discharge then charge.
I am using a mugen extended 3000mah battery and at 15% 10% and 1% it will stay there for some time before it starts to go down or turn off completely if it is reaches less than 1%.
I don't think you've lost capacity.
I believe you just did a quick check before flashing (and it was already charging before you started right?), and the battery gauge wasn't updated. I had this a couple of times while recharging. I take a quick look and think "this is gonna take another half hour". Five minutes latter I check and the charge led is green again.
Sometimes the battery metter lags a bit, you have to check it again to be sure when charging.
At least it happens to me.

a few cycles of full charge and discharge should put the battery meter in check...

Alrighty. I have done three so far. It has gotten better then the first time I got it. But its not perfect.
is it safe to discharge it to 0% so that it will shutdown? or what?
my last g2x battery lasted like 4 hrs on a full charge what is the best way to charge the new one? do i let the battery run out then charge it?
When you first get a phone, you should let the battery die before charing it. Then charge it completely after it dies, this will maximize your battery life. If you charge it right out the box, you're actually reducing the amount of juice the battery can hold.

That's not really accurate. Lithium Ion batteries have no memory effect like older batteries so charging them from halfway full does not reduce the maximum capacity.
What happens is the phone needs to learn to measure the amount of mAh from the phone and recognize what battery % that means. By taking the phone through the full discharging and charging cycle, the battery drivers pick up on this and will better report the battery level. With a poorly calibrated battery, you do not get less battery, but instead you just will not see accurate information about the charge level. For example, my first discharge went quickly to about 10%, and even quickly below 5%, but stayed on for hours between 5% to eventually shutting off.
The battery still will not die faster, but my phone thought it was much lower than it was, giving it the appearance of dying faster. Point is, you can do the charge/discharge cycle whenever, not just the first time, and it won't effect your long term battery health.
1) do factory reset
2) drain completely
3) charge completely
thanks!
thanks everyone for your advice!
I think it really depends on who you ask. lol Some people will say let it drain first then charge it fully. I have read info on battery maker sites that suggest when you get their battery that you let it charge fully for at least 8 hours, then let it discharge fully. They say to do this the first 5 charges to increase battery life.
When I get a new phone or battery that's what I do. as soon as I get it I charge it up overnight, then let it discharge completely for the first 5 charges. I can only speak by my experience and my experience tells me it makes a difference. Here is my reasoning: me and my ex gf went one day to get new phones. We got the same phone. She started using hers as soon as we left the store. I waited. I charged it up overnight fully and did the conditioning procedure. Our phones were pretty much mirrors of each other app and software wise. Her battery would die out a couple of hours before mine. Battery usage also didnt report any HUGE differences in consumption .
Also every once and a while I go into Clockwork recovery and wipe battery stats(after it's been fully discharged) and re do the conditioning process. It might just be a mental thing, but for me this seems to work
supposedly from htc.....
1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well
I heard/read somewhere that you should never let a lithium ion battery fully discharge. It supposedly shortens its lifespan every time you fully discharge it. Instead, you are suppose to just top it off and not let it remain on the charger, for extended periods of time, once its reached a full charge. YMMV

This is "more" true for everyday normal usage. Yes, you shouldn't constantly fully charge and fully discharge every time you use your phone. But for battery calibration it is necessary/beneficial.
I also hard that during the first charge after turning the phone off you have to strange on your head for ten minutes, then only use your left hand for the rest of the day and you will double your battery life

I go out at night mostly so by the time i leave the house my phones battery is about 75% full. I have the LG G2x. My question is sometimes before i leave i'll see that it's 75% full so i'll charge it back to 100% before i leave. Does charging the phone without it being drained damage the battery? should i just leave it alone next time i go out? sorry if this is already a thread just point me in the right direction.
Thanks.
You're not damaging your battery But if you never drain the battery completely, i'm not sure how good the battery will be after 6 month, so i recommend you drain it completely every couple of weeks.

There are several opinions about keeping battery health for more time. Recharging at 75% is not one of them, but it's not the worth of it.
Here's what i know and what i've heard:
* some manufacturers (laptops) have software that don't allow the battery to charge when it's over 80 to 90% - they say it helps on battery life
* it's common sense that you should recharge when you have 20 - 40% and do a full cycle once in a while (this is what i do)
In my opinion, charging only 25% of the charge in a regular basis will not really help to keep battery life...
I've personally had the best performance from batteries when I let them discharge as much as possible and then charge them to full without interruption.
some have also said that draining the battery too often can also damage it, is this correct?
They like to be ran down then recharged but not all the way down to nothing unless you are having a problem with bat life on a rom

Yes. You should not drain your battery all the time. Use normally, charge it when below 40% and yes, charge it back to full - that's the ideal thing.

+1 that is the best way. Li-on batteries should'n be drained completly because it can shorten their life.
I read somewhere that it is not important when you start charging your battery (20%, 60%...) but it's important that it finishes to charge up to 100% every time
I heard/read that LI-ION batter is good to charge when cap goes bellow 30%.
What is honestly the CORRECT way to do this?
I've seen some which says:
1. "Completely Drain your battery -> Wipe Battery stats -> Charge to full"
and some other who says:
2. "Complete Drain -> Charge to full -> Wipe battery stats -> Drain your battery -> charge to full"
and there are also a few who says:
3. Charge to full -> wipe battery stats -> drain -> charge to full
A little confused here
Also, is it absolutely necessary to calibrate everytime we flash a new ROM or Kernel? Or is it more of a "suggested" kind of thing?
Step 3 is best. Charging to full then wiping the stats will make the os know at which voltage the battery is charged to full, and then draining it till it turns off will tell the os at which voltage it is drained out.
Li-on batteries arent meant to be fully drained and they dont develop memory. Draining below 15% is not recommended
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Over-discharging Lithium-ion
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.
Battery manufacturers ship batteries with a 40 percent charge. The low charge state reduces aging-related stress while allowing some self-discharge during storage. To minimize the current flow for the protection circuit before the battery is sold, advanced Li-ion packs feature a sleep mode that disables the protection circuit until activated by a brief charge or discharge. Once engaged, the battery remains operational and the on state can no longer be switched back to the standby mode.
Do not recharge lithium-ion if a cell has stayed at or below 1.5V for more than a week. Copper shunts may have formed inside the cells that can lead to a partial or total electrical short. If recharged, the cells might become unstable, causing excessive heat or showing other anomalies. Li-ion packs that have been under stress are more sensitive to mechanical abuse, such as vibration, dropping and exposure to heat.

Yes that is correct, discharging it a full cycle below 15% is not healthy for the battery, IF you do it very often. If you read it further in the article it states that you should and can re-calibrate the statistics every 40 partial charges or 3 months. Discharging it a full one cycle every now and then is OK. Not every week!
source: http://batteryuniversity.com/learn/article/battery_calibration
Wiping battery stats does nothing. It's a myth debunked a couple of weeks ago by Dianne Hackborn.
Skip that step and just charge it whenever you want. Every couple of months allow a full discharge and do a full recharge. Done. No hassle, no root needed.
EDIT: Gah, sorry for the post revival, was searching for something and not paying attention :/
I still currently own a Samsung galaxy s3, and I have been charging it to full 100% and letting it drain fully until it shuts off. Once i get S8+, should i still be doing this or will that mess up the battery over time. Do you guys drain until 10% , and charge up too 90%? Was curious.
Batteries have so many charge cycles at a certain depth of discharge. My understanding is you get more charge cycles if you discharge less.
So, unlike removable battery phones, I plan on leaving this phone on a charger as much as possible and usingbt the battery when necessary.
The battery change on this device looks hairy!

I See, does the phone stop from overcharging the battery once you reach 100%?
It's best to keep it between 20%-80%
Also, pretty much all lithium ions are nearly impossible to overcharge.
You generally want to keep your batteries between 40-80% I believe is the sweet spot. I will not let my battery go below 30% generally and I top it off whenever available. Forgot where I read it but as others have said your phone has so many charge cycles (500 or so before the battery starts losing a certain compacity). And if you constantly charge from 0-100% each time, you are using a full charge cycle. Instead if you charge it at 50%, you would be using half a cycle, etc.
Someone can correct me if I'm wrong.

Ive read similar things. I generally follow this and try to charge before i reach 20% up til 89%.
Ive also read somewhere to deplete battery to 0 atleast every few months if not sooner. Dont know if its true though.
