[Q] just got my new g2x how should i charge the battery?

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

Charging from 99% to 100% seems to take long

I noticed this on my old S4 as well. 99% took the longest to charge up to the next %. Anyone know why this is? My phone was charging at 99% for like 15 minutes. I also noticed that using the phone from 100-99% goes very quick :laugh:

This is perfectly normal. Think of it as inflating a balloon. The last 1% will be really hard and yet it will deflate as fast as the rest. It is not recommended to push that last 1% too often. Ideally you want to stay between 30-70%.

He is correct some say 20-80%, best example is Samsung laptops, mine had an option in the bios of topping charge of at 70% to prolong battery life.

Check out my recharge experiments: http://forum.xda-developers.com/z3/general/xperia-z3-battery-life-recharge-t2916773

I heard somewhere that is a solution so battery dont became overcharghed.
And what kills battery capacity is if it became static. There must be electricity flow trought battery to prolong it life time.

Your only supposed to charge your phone to no more then 70%?? First i heard. Never heard that before, Interesting.

I looked into the same thing last month.
https://discussions.apple.com/thread/4465051?tstart=0
When possible avoid frequent full discharges. Instead, charge the battery more often. There is no concern of battery's memory when applying unscheduled charges. A high residual charge before recharge is a benefit rather than a disadvantage for chemistry of Li-Pol battery on all iPads. The best way is to keep battery between 40% and 80% charged. After LiP battery of iPad is charged to 80% capacity it switches to trickle charging with a potential to cause plating of metallic lithium, a condition that renders the cells unstable. One more incentive to keep battery of iPad between 40-80% is the rate of the charge loss when gadget is not in use. The charge loss amounts up to 6% per year when battery is fully charged, but only 2% per year when it is half-charged. Nevertheless, short discharges with following recharges do not secure the regularly calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30-40 charges fixes this problem.

What is a charge cycle?

A Li-ion battery has a limited numer of charge cycles, but what constitutes a charge cycle? According to some people a charge cycle is used every time the charger is connected. Another opinion is that only a charge from 0 - 100% consumes one charge cycle. So how is it really? If the first assumption is true then one should only charge when the battery is almost emty. If the other one is true then it's ok to charge at any time.

A charge cycle is the process of charging a rechargeable battery and discharging it as required into a load. The term is typically used to specify a battery's expected life, as the number of charge cycles affects life more than the mere passage of time. Discharging the battery fully before recharging may be called "deep discharge"; partially discharging then recharging may be called "shallow discharge.
Apple Inc. clarifies that a charge cycle means using all the battery's capacity, but not necessarily by full charge and discharge; e.g., using half the charge of a fully charged battery, charging it, and then using the same amount of charge again count as a single charge cycle. -Wikipedia

Ok, but that means that charging the battery a lot instead of waiting until it's almost completely drained, shortens its lifespan.

Ideally, a Lithium based battery is "healthiest" at or about mid level. A full charge cycle is technically not 0-100%, as these batteries (at least in consumer electronics) have circuitry built-in to prevent overcharging, overdischarging, and shorts. Overdischarging can cause what's called runaway discharge, where it'll keep discharging even if not connected to anything or the device is turned off. Heat, possible fire, and even explosion. Those Dell and Sony laptops that were catching fire several years ago? That was because the protection circuitry was faulty. And why you should always buy OEM factory batteries, or ones made by reputable companies like Zerolemon or Anker, and not cheap Chinese knockoffs. Hobbiests (flashlights, R/C equipment) often use unprotected batteries since they can get a bit more capacity out of them, but this is dangerous and requires monitoring and judgement.
So the answer is a charge cycle is from 0-100% and back down to 0% (or the opposite; charged, discharged, then charged - depending on your point of view), where 0% is the point where the circuitry within the battery and/or the device itself cuts the power.
There is no need to "condition" lithium rechargeable batteries (ie: fully drain them, don't use until fully charged, etc); this is a holdover from the days of nickel-cadmium (Ni-Cad) batteries, which did require conditioning for optimal performance.
The main destroyer of a lithium battery really isn't even the charge/discharging of it, but rather the heat associated with it. For example, one can keep a battery charging and charged at 95-100% while playing an intense game, downloading a large file, or running a wi-fi hotspot, but this sill quickly destroy the battery, even there's no actual "cycle" happening. The ~500 charge cycle figure assumes a typical usage of training and charging. The reason a battery is "healthiest" at mid levels is that this is where there's the least heat being generated.

Yeah, I have kind of adapted to the thought that charging whenever doesn't impact the battery in a negative way. So if my charge is 80% and I'm going out for the day, I still charge it to full 100%. If however (as the first answer suggests) this consumes an extra cycle then it would be best not to charge it. In the past this didn't matter so much but with many phones these days it's hard or even impossible for the user to replace the battery. This makes the answer to my question more important...

80-100% is not a cycle, it's 20% of a cycle. However, it is the worst part of the cycle (higher voltages, more heat). Ideally, for the battery's health and longevity over the months/years, it'd be best to keep it between, say, 30-70%. But this is impractical, potentially impossible for some, and, frankly, dangerous.
That's why I'll only buy phones with replaceable batteries. Either instantly, or without terrible difficulty when the battery hits that ~500 cycle mark. I have 3 phones: A Galaxy S4 (with a couple spares, including a 7800mAh Anker), a Nexus 4, which I've replaced the battery on, and a OnePlus One, which I know I can replace if/when I need to. I'll never get something like a S6 or Note5 or iPhone where battery replacement is nigh-impossible.

Yeah, it's very annoying that not batteries on all cell phones are user replaceable. And we can exchange them on some phones anyway with a little trouble, but as you write it's completely impossible with some. I put in the charge if my battery is 50% or something and I'm going out later. This should consume only half a a cycle and it's practical for me.

I now charge when the battery is like 75% before I'm going out. Is this ok or should I let the battery drain and then charge? The latter I did for a long time with a phone I had, and the battery had great performance until I sold it.

Proper Battery Charge and Depleting

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.

Wrap charge

I apologize in advance if it's was already asked
So i'm wondering how it works. Does it use warp charge till it reach 100% or it goes normal like at 50 or 70%?
I noticed it's slow 90 to 100 whereas i see warp charge logo

I'm on havoc so idk if it's the same, but havoc shows the output, from what I can see its between 5-6amps until 50% and slowly tapers down from there to 1 amp between 90-100%

Never charge to 100%, it shortens the battery lifespan a lot. It's best to use it on 20-80 charge range.
After 80% the charging speed slows down like any other phone.

The about 20/80 has also worked out well for me on all my devices...

This is a fallacy. I charge my phone to 100% everytime and after a years time my battery still has 93-96% capacity. The damage is done if you let it discharge below 10 or 15%. Lithium ion batteries looked to be charged more frequently and when the battery is above 75%. The higher the battery percentage the more charge cycles it will have.

Thanks for the lifespan tip. Didn't know about it

I didn't understand the last part of your post, if you charge till 80% you'll use very little charge cycle. The most of the battery wear is done on the last 20% charging. Even if you store a li-ion battery at 100% it get damaged very quickly.
They like to be charged often and stay on 40-50% average charge level. If you do that the battery is going to last 3+ years.
If you charge overnight to 100% and top up every time you'll need to replace the battery in less than 1 year.

This is not the case. Charging the phone more then 20 or 25% or more results in more charge cycles. Look up BatteryUniversity.com and it will explain it to you. The damage above 80% is done if the charging per doesn't reduce and you charge to quickly from 80-100%. This is why the battery reduces charging speed after 80% down to a trickle charger from 95% to 100%. This is built into the charging tech so there is no battery damage charging your phone to 100%.
I charge my phone to 100% everyday and something twice in a day and never have battery issues or reduced battery capacity. My phone lasts as well after 1 year as from the day it's purchased.

Read carefully, it says exactly what I'm telling you.
I'll attach a screenshot of the website that you suggested, it's shows what I'm saying that if you charge to 80% instead of 100% you get three times more battery cycles of lifespan (850-1500 vs 350-500).
Also the second screenshot shows that if the battery stays at 100% it degrades much faster (only 80% capacity after one year vs 96% capacity if stored at 40%).

And if you charge routinely from 75% or higher, you can achieve up to 1200 cycles for lithium ion batteries. I'll do my way as I don't lose battery capacity after a years time. This is info from battery University. Been doing this for years (since the note 3). Again I'll say, it's not charging to 100% it's if your charge to quickly from 80% to 100% it's what's bad for the battery.

If you read what you posted it's the temperature During the charging that reduces the charge cycles. There is no heat in a OnePlus phone with Warp or Dash charging. Depth of discharge also increases cycles if you charge when the battery had more charge. For example... Charging at 25% or less gives 250-300 charge cycles, 25-50% gives 350-500 cycles, 50-75% 600-900 cycles and above 75% up to 1200 cycles. I'll continue to follow that by battery University and continue to have a battery that doesn't lose capacity

I'm not going to convince you but I don't like the pread of disinformation.
If you read the graph in the picture it show that what damages the battery is both from high temperature and high charge level. Just look at 25 degree row:
40% charge - >96% capacity after 1 year
100% charge - >80% capacity after 1 year
Things are even worse at 40 degree: 85% capacity vs 65% so 20% extra battery capacity lost.
Remember that when the battery capacity is at 80% means the battery is gone because it cannot cope with the ampere under load and the phone will shut down. This after 1 year without taking consideration of the extra damage while charging to 100%.
Now I'll copy and paste that part from the website:
Most Li-ions charge to 4.20V/cell, and every reduction in peak charge voltage of 0.10V/cell is said to double the cycle life. For example, a lithium-ion cell charged to 4.20V/cell typically delivers 300–500 cycles. If charged to only 4.10V/cell, the life can be prolonged to 600–1,000 cycles; 4.0V/cell should deliver 1,200–2,000 and 3.90V/cell should provide 2,400–4,000 cycles.
4.20v is 100% charge
4v is 70-75% charge
Be careful that's tge voltage of the cell, not the charging voltage.
I agree with you that slow charging makes less damage but still charging from 75% to 100% makes hugely more damage to the battery than charging from 20% to 80%.

Yeah I can say the same about disinformation which is what I said to you to begin with. My op6 which I bought and had since launch still gives me 9-11 hours is screen on time today like it did on day one. That phone like all the rest of my phone is charged to 100% every day, normally from about 70% or higher remaining battery when put on charge. Using a few different apps my battery capacity still shoes 95% capacity.
Again, charging to 100% and damaging your battery is a fallacy. Charging to 80% is fine but your depth of discharge is greater putting more stress on a lithium ion battery.

That's is from lab test made from scientist, so I trust it.
Also no one tells you that you need to wait 20% to charge, you can do 40 to 60 or 30 to 50 but i can assure you that I've got a phone a xiaomi mi 5s 3 years old same battery charging 20% to 80% and is still usable, I'm using it as a second phone.
My previous phone was a galaxy note, I was charging it overnight and charging it to 100% often through the day, i replaced the battery three times in two years.
Thats my experience.

So guys what you recommend for charging pattern for best battery health ? I'm rly lost from what u said...
Me I charge my phone every night with very small charger I think it's 1amper maybe lower.
I never let it under 25-20 % and always charge it full with zero heat and takes long time to charge because of the charger.
If I wake up to go toilet and night and it's charged I removed it and that's it..

I never let it under 25-20 % and always charge it full with zero heat and takes long time to charge because of the charger.
If I wake up to go toilet and night and it's charged I removed it and that's it..

The best charging pattern is to always keep the battery near 50% and do frequent charges through the day.
Don't charge overnight, leave the battery at around 50% when you go to sleep.
At the morning, when you wake up plug in the warp charger so you can charge to 80% before going to work.
Charge over 80% only in special circumstances when you need long battery life.
Try to never go below 20%.

I recommend you to plug your phone 1h before sleep and charge it fully or do it in the morning. You may increase your battery life with all that slower charging, up to 80% etc but really? Is it worth to resign from that cool Warp charging feature just for extending your battery lifespan and you won't even know how much it will extend? And you can even exchange the battery at authorised center for about 20 bucks.

I thought the myth about leaving the phone charging overnight breaks stuff was explained away already. There's stuff that runs in the background that improves the usability of the phone and decreases battery drain.
Read this monster post for full info. Not so much looking after the battery but system optimization. Warning. It's a big read. I've been leaving my phone charging overnight for years. I still have a OP5 that's being used daily and still gets fairly impressive SOT. Other thing is, "we" tend to change our phones quite often. SO I just don't worry about it too much and use the phone the way I want to use it.
