Charge battery before initial use?

[pauly814]

Should I charge the battery before turning on the phone for the first time?

What’s the best thing to do for the S20+ right after taking out of the box ?

 

[cardboard60]

I bought my phone from Best Buy.
I had them to totally disable Bixby.
Let them setup the phone..
Think they charged me like 10.00
I was 50 miles from home.
No internet in the car to do Nothing.
I plugged it into the power supply in the car and started using it.

You know I can't drive 50 miles without using the phone.

I don't baby the battery.
Don't run it below 25% either.

Yes. Bring it up to 72%.
Full charges and heat degrade LI batteries faster.
LI take small charge cycles very well; drain to 30%, then charge to 72%. My Note 10+ will do that in about 15 minutes.
Fast charging causes less heat build up it seems too.

There is no need to do any of that. The battery percentage reported by the phone is a relative number and does not actually represent the absolute capacities of the battery.

Charge the phone to 100%. The phone's charging circuit will regulate the charge and will not damage the.

What you are saying is technically true about a standalone lithium-ion battery, but the phone has smart charging capabilities and won't push the battery beyond its safe limits.

Incorrect. Do not charge to 100% unless you need too.

I just start using it as normal. Batteries are already broken in by the battery manufacturer, so I'll charge to about 80% and call it good until time to charge again.

I always lay mine on the Samsung charger.
Let it charge till the light goes green.
It runs down to 70%.
I stick it back on the Samsung charger.

Never had a battery problem.

If you want to keep phone forever.
Have the battery replaced.

whenever I get a new toy, I am usually too impatient to wait for it to charge. there is usually enough charge to get it setup. It is really up to you and what you want to do. you can charge it and wait, play with it then charge or plug it in to charge and play with it while it is charging. three choices and any will work

Yep. !

That's the worst way to power cycle an LI pack. The higher the voltage and temperature, the faster the LI cells degrade.
The difference between doing that and the way I advised to is literally hundreds even thousands of lost full charge cycles.
A partial charge of 72% ran down to 30% is not a full charge cycle. It gives you a lot of usable run time with minimum battery degradation. LI's charge fastest through this voltage range as well. Topping it off will quickly kill the capacity of the LI pack.

200 full charge cycles vs over 1000+ full charge cycles is the price you pay from charging to 100%!!!
No joke...

Battery charges to 100%.

Runs just like the day I got the phone.

You know if there is a problem with the phone.

You can walk into any store and buy a new phone.

I didn't buy the phone to Baby it.
Or worry if its getting charged the proper way.
It had nothing in the instructions on how to charge it.
No body selling the phones has ever said.
Look for proper charging.

This is how you charge it..

Every phone I've ever gave away, or traded it.
The battery worked fine.

Now you are worrying about it I get a maximum number of charges out of it..

Most people don't keep their phone for over 3 yrs anyway.

This is a recurrent discussion that never seems to get settled. I think the bottom line is that if you absolutely have to prolong your battery life as much as possible (i.e., beyond 4-5 years, which is unlikely to be necessary for the average phone user), then by all means, don't charge up to 100% and don't let it discharge too deeply (I believe this is why Tesla recommends setting the max battery charge to 80-90% for daily use, not 100%). But for most people who won't keep their phones beyond 2-3 years, I don't think charging to 100% is detrimental in a practical sense. From a usage standpoint, limiting the battery use to only about 40% of its capacity per charge can be unrealistic.

the great debate. both sides think they are right, both sides have their points, both sides claim there is scientific proof and both sides can point to an online source that supports their claims, It really does not matter for most users anyway. personally, when home, I always leave it on the wireless charger. never had a problem.

I really didn't care when the device had a removable bat, but with the Note 10+ it's a big deal.
One of the worst phones to do a bat replacement on.

Not really much of a debate; nearly pure science.
You take the best practices and integrate/implement them as best you can with the way you use the device.
Do the math, if you do 200 full charge cycles, 1 @ day, in little more than half year your battery capacity will be whacked to something like (not looking at the graph, from memory)70% of what it was new.
It just keeps getting worse. At this point the 100% charge advocate will have no more Ahr capacity than my device that's only charged to 70%.
However the shorter cycled battery will still have many hundreds of short cycle charges left.
By than the full cycle battery will have long become useless.
I don't know which is better?
One battery for the life of the device or 2 or 3 batteries over the same time span?

With fast charging it's easy to go past my charging V+ set mark, literally it comes up 10% in minutes.
So I hit high 80's and 90's% more than I like... nothing's perfect. Android should have allowed for settable charging limits long ago. They want to sell phones...

With this method of short charging the beautiful thing is if you need a full charge in the future, most of the capacity is still there even 2 years latter... waste not, want not.

you just proved my point

Do what you want. Actions have consequences.

I've never seen anyone point to sources to back up the claim that charging habits don't matter. I will say that how much attention you should pay to it depends on your usage. I'm a heavy user and would typically have to charge my phone 4-5 times a day. Even when using best practices, I can see a decline in capacity after the first year of use, and I usually keep my phones 2+years. I just got an LG V60, and so far I'm only charging it about twice a day. Hopefully that means it'll retain capacity much better than my prior phones.

I have over the years in the different tech forums I belong to. how to charge batteries efficiently is almost always a hot topic when it gets started and it is almost always about how to count cycles.

Temperature plays a big role too. 72F is considered an ideal operating/charging temp, practically hard to do many times.
The higher the cell voltage, temperature and duration of the insult, the greater the damage.
The worst thing you can do is store an LI fully charged at high temperatures. It compounds the damage done.

I use this phone a lot and get by with 2-3 partial charges.
I give it a break when charging if it gets noticeably warm.
20+20% is still 40%
On a 25 watt charger 20% is a couple of songs worth of time.
It's the voltage potential and temperature that count with LIs.
They wuv brief charge cycles, being kept cool and keeping under 72%. They have absolutely no charge memory.
Much different from other battery types which creates a lot of confusion.

I get all of that, but greater use means greater wear, even with best practices. My last phone was my first with a sealed battery, so I got even more strict. I went so far as to revert back to a standard 5V2A charger, which resulted in about a 10°F drop in charging temps.
