Battery - to drain or not to drain? - Samsung Gear S3

Hello,
What type of battery does S3 have?
I use AOD so I end my day with approx. 50%.
What is the best way: to charge it every day or to let it to drain out?
Thanks!

Lithium Ion.
Avoid full cycles. Partial charge is better. Google "battery university" for more info on caring for lithium ion batteries

Exactly - Battery University is a great resource.

Cliff note:
Keeping the battery between 20-80% will make it LIVE the longest.
Makes sense
Awesome article, thanks for the thread.

If I read the article right, I should not leave my phone plugged in over night? If i don't that it will be drained when i wake up in the morning.

Your phone will stop charging when it reaches 100%. Don't believe anyone saying an 8 hour, or overnight charge is needed when it comes to lithium batteries. Over charging and over discharging lithium batteries is dangerous which is why they have built in circuits to prevent this.
yeah, After having purchased an electric bike kit last year, I've studied up alot on lithium batteries, and the article and it's author doesn't mention anything about a BMS (or battery management system).
I'm sure every cellphone has a BMS making sure that the battery does not overcharge or undercharge. It will either stop charging the battery and will shut off the device when battery gets critical. 100% charge does not mean 100% but actually is 80% then the BMS stops charging, and 0% is actually 20% then BMS shuts of device.
Yes you shouldn't be doing a "full discharge" on lithium batteries, and yes you shouldn't leave the battery on the charger for more than a week (overnight is fine is you're charging on a daily basis though)
The best way to exercise and increase a lithium batteries total life cycle from say an OEM suggested life time of 500 cycles to upwards of 3000 cycles, is to start recharging at about 50%. This way you extend the batteries life. Hope this helps.

[Q] Best Charging Habits

Is there a certain way or frequency to charge your device that prolongs battery life?
I usually take the phone off the wall charger in the morning and in my commute to work while streaming podcasts, spotify, or on phone calls my battery is usually around 70 when I get to work.
Would it be better to charge once the battery gets really low or keep it on the charger while at work? I need pretty much 2 decent charges a day to get through an entire day. Thanks.
Frequent and partial charging is best for Lithium ion batteries. Full discharge/charge cycles shorten the life of the battery. Also, not necessary, since Li ion batteries do not suffer memory effect like older technology batteries (like NiCad). A few cycles of discharging to 10% or so (not to shutoff) then full is good when the phone is new, to calibrate the battery meter correctly. Otherwise, the best practice is to charge as often as is convenient and practical.

[Q] To Discharge or Not To Discharge

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.

Battery life

Is bad for battery life if I charged my phone every night no matter the percentage of battery left?. For example today is 62%.
It's best not to charge your phone overnight because it charges so quickly that it can sit at 100% for several hours before you take it off the charger in the morning. The longer a lithium battery spends at peak voltage (100%, 4.2v), the faster it degrades, meaning your long term battery life will suffer
It's also not a great idea to let a lithium battery fully discharge too often. There's a kind of a sweet spot between 30% and 80% that, if possible, you want to try to keep your battery within when you can.
So it's best to do smaller top-up charges if you're able to. About once a month you should calibrate the high/low flags though, you can do this by fully charging the phone, then fully discharging it, and then fully charging it again.
There are a couple of really good detailed articles than can explain it far better than I can:

Charging Battery

What's the consensus on when to charge and how long?
Is it safe to charge the S7 battery overnight, even if only around 50%? Or is it better to wait until your almost dead?
One of the I.T. guys at work was saying you should wait until you're below 20%, then always charge to 100%.
Just charge it whenever you want, this isn't the 90's or 2010. You'll probably replace your phone before you start to see it majorly affecting your battery.
You'll get a very slight improvement in overall battery life if you keep the charge between 25% and 75%. But we're talking very small. But yes, it's perfectly safe to charge your phone over night. The battery / phone / charger electronics won't overcharge the battery.
What you do want to avoid is draining the battery down to zero, or close to it. If at all possible, don't let the charge drop below 20 - 25% on a regular basis.

Thanks for the info. I thought it was beneficial to charge all the way to full?

Lithium Ion batteries are different than older technologies, such as NiCad and NiMH. These batteries suffered from the "memory effect" (although not as badly as most people thought), so it was good to charge those fully. If you always charged them to, say 80%, they would eventually only take an 80% charge. Li batteries don't suffer from a memory effect, so you don't need to worry about that.
The other thing is that Li batteries hate three things: excessive heat, being fully drained, and being overcharged. Tesla stops charging when the battery pack reaches 75% of full charge, and displays that as a full charge. Similarly, they consider a 25% charge as "empty." Then again, a Tesla battery pack costs something like 10,000 bucks, so it's important to as much as possible to maximize the life of the pack.
