After flashing the recommendation is to recalibrate the battery, or let the phone do it over several charging cycles. Any idea how this would work using two batteries?
I have two genuine SGS batteries and swap them over when necessary. Does always keeping one charged and swapping mess the stats up.
I am in the same boat. v9.5 ROM and two Samsung batteries. Swapping them does not seem to make much difference. I did do a few full discharge and charge cycles to begin with with the one battery. Getting the same run time out of each battery now.
No real difference if both are fully charged .
The rom drains the battery not the stats the stats play less of a part than people think .

Just bought a 3500 mAh battery off of ebay. I was wondering do i need to condition this battery? If so what are the steps? I see conflicting info all over the place.
thanks!
Conditioning? Like calibrating?
Some batteries said to drain it completely first then charge for 8 full hours to condition it. That's why i was wondering if there was anything i needed to do to get the maximum amount of battery life out of it.
That's a great question. Usually I let it drain fully, then fully recharge. It's just an old habit of mine with new batteries.
usually when you get a new battery itll have some charge in it you need to power the device on let it drain completely till it wont turn on at all then let the battery charge 8-10hrs and you should be good.
Are there any disadvantages to having the phone plugged in a frequently as possible (e.g. charging over night, car charging, charging while at work)? I have been favoring 897 leaks over 9000 roms mainly because of battery life. I have been a fan of Apex roms and now that A11 is out I want to give it a try but I know I won't get the same battery life as Illuminance. Could I damage my Captivate from frequent charging?
Now i could be wrong, but frequently charging *may* reduce the life of the battery....i believe every batter has a certain amount of "charging cycles" it can have before the battery begins to lose charge quicker...again, i could be wrong..
True, batteries do have a certain account of charge cycles, but a charge cycle is a 100% drain and back up again.
So down to 50 then charge, 75 charge, 75 charge, is only 1 full cycle.
So whether you wait to charge til it's dead enough to not run the phone (it actually shuts off before true 0% to save the life of the battery) or you grab some spare juice when you can, your battery should have about the same life span.

Ya this is true but I find I that I get much better battery life if I do a bump charge. Ive charged to 100% on the phone screen, turned off the phone, plugged the charger back in, and had it charge for another half hour until it hit 100%. So I dont know what it is about charging in that fashion that works for me but it really seems to help. I also am pretty good about cycling my battery 0-100 100-0 so that may help.

bump charging will kill battery life long term..
Also, be careful with car chargers. Some of them are designed to charge faster which will also shorten the over all life of the battery.
Lithium batteries don't like to be drained fully. The best time to charge is 30-40%. Also lithium doesn't like the "fast" charge. Basically be easy on the drain/charge/level and it will last longer.
The 1/2 hour you're talking about is because the last 5-10% takes the longest. You can actually charge from ~40%-80%+ very shortly due to the way Lithium works.
As I said above, the phone shuts off before the battery reaches 0%. You notice it still has enough power to run the charging animations even though its too dead to boot.
the phone also stops charging at 100% let drain to 95 and back up, to prevent overcharging.
both are to save the lifespan of the battery.
Discharging below three volts will cause damage. Charging over four point two volts will cause damage. Charging at a greater rate than one C will cause damage. One C is equal to the capacity of the cell. Our stockers at 1500mAh should not be charged at a rate greater than one point five amps. I believe the stock charger outputs 800mAh, or point eight amps. Any damage to the cell will definitely shorten life. The more you use a battery the faster it will die, true with any type. Hope this helps someone.

I don't really see this as a matter of choice. My phone dies daily, so I have to charge it daily; I have to bite whatever happens with it anyway. If it helps, I got my phone on launch and have been using the same battery through my warranty replacements. My battery maxes out at roughly 15 hours of moderate use, 20 of light use.
frequent charging reduce battery life so it is better to charge when ur battery is left with 15% or below and charge it completly

This is very true of Lithium ion batteries. They like to be kept topped up constantly. Not letting it go to 0% consantly helps. This is very different from NiMH or NiCd, where the "memory" effect requires you to completely discharge the battery before next charge.
The best way is to just put the phone on charger whenever you are not using it - if ever - just plug it in and let it sit till you use next time.....
FFS how many times must I say it? THE BATTERY NEVER REACHES 0%!!!
There is ALWAYS some amount of charge even when the phone won't come on.

Very true. If you discharge a lithium cell below three volts, you run the risk of it catching fire or exploding.
Should've mentioned earlier that as the battery degrades, it loses capacity. This is what causes them to seem they're not "lasting as long" or "draining faster".

How should I charge the x8 or any li-Oh battery for that matter? What do you do?
Leave it until empty
Charge just before dying
Charge whenever I have the opportunity.
Wrong thread.
I charge it when it dies.

I charge my phone anytime! If battery has 70% and I know that I'll use it next day very much I always charge it to 100% !
yh
Yes i charge it whenever I can
Just when it dies
whenever it dies
I charge whenever it dies
Well, a little research :
Avoid fully discharging a lithium-ion battery! Unlike Ni-Cd batteries, lithium-ion batteries' life is shortened every time you fully discharge them. Instead, charge them when the battery meter shows one bar left. Lithium-ion batteries, like most rechargeable batteries, have a set number of charges in them.
I also just recharge whenever I think necessary.
i charge whenever i want

i charge as often as i can, to make battery long last
Great Thread
Hm, great thread..I charge my X8, when was 3% of battery..And always charge to 100%..
you should avoid letter a li-ion battery get below the 20% area as this damages the cells in the battery li-ion have no memory effect unlike ni-cad even ni-mh battery had no memory effect but they did need a big first charge
I Charge my battery, just before dying. :laugh:
i charging my x8 before it dies.
@Deftone and @ androidnerd2
our battery is lithium polymer not lithium ion.
so we can charge it anytime we want its life is not compromised.
and ya its true we should not use it till the end of its charge.
but our mobile takes care of it. it shuts down phone saving some charge in battery which is always needed otherwise battery wont even charge if voltage drops down to large extent..
Lithium batteries in general are better to be discharged as much as possible before charging.There are several rules for optimal charging like turning device off or not topping off the Ion based ones but in general dont charge them unless you know you ll need it and dont be afraid to let them dry before charging them again.There is no memory effect on Lithium batteries but there is a Life cycle that you can extend with less frequent charging.

Does fast charging Daily overnight reduce long term battery health? Is it a better choice to only fast charge when necessary and normal charge overnight?
I've reading about this lately but never came across a definite answer. I was hoping that someone could answer this for me.

Depends on quality of the battery and the capacity of the charger.
In general batteries are charged with 10% of the capacity. For the Nexus 6 battery with a capacity of 3200ma/H, you need a charger with a capacity of 320ma. Assume you need 10 hours to fully charge the N6 with a charger capacity of 320ma.
In theory the N6 charger with his capacity of 1600ma will charge 5x faster.
But the the N6 charger is not permanently in this turbo mode. After some time it switches back to a lower capacity when the battery is partially charged.
Now your question. In turbo mode charger and battery dissipates heath and that is not good for the battery. So normal charge will be better.
But there is also battery drain when you use the N6, especially the nice amoled display.
Battery drain causes also warming up of the battery.
So the total battery life depends not only on (turbo) charging. Also the way the N6 is used.
