Charge battery before initial use?

[Mooncatt]

I've sit there and watched a dude with a heat gun and a guitar pick break one open.
Take a couple screws out.
Remove the battery..stick a new battery in and put it back together.

And that guy was most likely trained and experienced to do so. They make it look easy, as all professionals do in their respective jobs, but your average consumer would most likely shatter the glass and do who knows what other damage trying to do it themselves.

I have a iPhone 5S sitting in the drawer.
Works fine.
Battery charges to full.

How old would that be.
I never babied the phone.

works fine

yes...but how long can you use it for? how long would it take to go from 100% to 0 if you were to use it anything like you used your current phone? would it get you 6 hours of Sot? Could you unplug at 7Am and go the whole day and maybe have to plug it in when you got back from work? Or would you lose 50% with an hour of youtube? try it. i think we all know the answer.

On the 10 the bat is glue directly to the screen. Even experienced phone techs break them. I've repaired 2 Canon pro bodies... and I wouldn't attempt doing a 10.
I know better. Most likely a less than optimum outcome.

Lead acids are damaged by vibration as well. Very intolerant to deep discharge cycles and especially to sitting in a fully discharged state. Heat doesn't greatly effect them though.
There are modified ones for better vibration tolerance and deep cycling applications even hydride deep cycling/cranking ones like Optima Blue Top I have.
Got in good condition for $35... every now and then

Yeah , but mostly cheap battery that are bought like exide,champion some of them they put thinner plates between the cells and what you mentioned can happen and short them out

If you want to have fun connect two together but reverse the polarity

Yeah the newer lead acids batteries aren't that good.
Good for two flat line discharge disasters at best.
Probably 3 years with normal use, tops.
One reason I would stick with the Optima battery line.
Lower internal resistance too.

Oh that's real fun , best touch a coil boot while checking for spark , gets you going real quick

I've actually felt the static charge from a lighting bolt that hit close by. When haven't lived till you've been almost struck by lightning.

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 ?

This is what I firmly believe. Turn your phone on first and set it up. Then go into device care > battery and DISABLE fast charging. I cannot stress this enough.

Power your phone down. Plug in the charger and charge to full. Once full, continue trickle charging for 30 mins. Unplug the charger, power the phone on. Plug the charger again for a few secs until it registers completely full. Unplug the charger again.

And you're done.

I've read some of the comments in this thread from other users about battery maintenance. It is an UNDISPUTABLE fact of lithium ion batteries that best practice is small, regular charges between 40 and 90%. Topping up to a maximum of 80% is even better. And overnight trickle charging at 100% is worst practice.

The latest Porsche EV limits maximum charge to well below 100% for this very reason. To preserve battery life.

I went to a batteries plus store on Conroe, Texas.

Batteries plus don't carry cheap batteries.

There was another 2 customers that left their phone while I was there to get the batteries replaced.

Charging to 100 percent doesn't matter. Draining it to Zero is the biggest thing to avoid.

10/4

I understood not to let it get below 30%.

Why? Show me anywhere where it says doing either is advisable?

This is a standard thing for lithium ion batteries. To keep it between 30/40% and 80/90%. You can look it up literally everywhere on the net all saying the same thing. And I mean specialist battery sites also. This is not really up for discussion or debate. It's just the facts for lithium ion batteries.

I posted that already. Discharge rate is critical. As long as it doesn't get below it's critical voltage threshold I believe that wear in the lower charge state is far less than in the higher voltage states. The controller will not allow a zero discharge to occur. 30% is probably better than 20% but not near as critical charging to near a full charge unless you are drawing a lot of current. You draw more current at lower voltage for reasons I already stated ie watts power total consumption. That doesn't mean it is a gross insult though and isn't as bad charging to near a full charged state. Higher temp from the charge and it's more reactive because of the higher voltage potential on the electrodes causes more damage.

To clarify when you notice a significant increase in battery percent dropping off nearing the knee in the curve at 20%, time to charge. If the the device's power consumption is high best to stop using around the 30% mark or before.
If at say at night and the power consumption is less going to 20% with not impact life significantly.

The lower the voltage gets, the greater the discharge rate assuming device watt hour power consumption remains constant. At the knee around the 20% point discharge increases significantly ie more wear.

Gotta love it when people quote Battery University as if it's something new and never been discussed here. This always comes up when someone asks the question. Just search the threads.

If you want to go around metering your phone, go for it.
Personally I say enjoy your device and use it the way you want to. I've never had an issue with severe battery degredation as long as I've avoided discharging to zero.

Battery University still seems to be the best source. From their home page:

"Battery University is sponsored by Cadex Electronics Inc., a technology provider specializing in the design and manufacture of advanced battery packs, BMS, chargers and diagnostic devices."

You can't get much more insider than that.All other articles that go into any of the technicalities, including the one you linked to, all refer back to BU. They also seem to regularly update their articles as needed. I'm open to reading other sources, but BU is currently the one and only primary source I know of.

This isn't just Battery University, this is universal. All sites relating to lithium ion batteries say the same thing.

Which is don't overnight charge, don't charge everytime to full, don't discharge below 30-40% and generally battery longevity is best when operating between 30/40% and 80/90%.

You say just use your phone and enjoy it. You'll enjoy it for longer if you follow good charging and usage habits.
