So whats the best method for a first-time battery charge?

---

Do i let the phone shut off from the battery reaching 0%, then charge it to 100% and be on my merry way?

I've read multiple theories, but I think u should take it down out of the box, then shut off and charge to full...I remember ASUS recommending that to a media outlet when the Transformer 300 came out a few weeks ago...so that is what I am going to do when I get mine.

Thats exactly what I did, I let mine completely die and then charged to 100%.

Be careful with how you charge the phone, rather with how low you let it get.

Depending on how technical you want to get about it purposefully letting a battery drop to absolute zero can cause some odd chemical reactions that while not immediately evident can some times shorten battery life.

I would recommend taking it out of the box and using it until it is low but not dead. Maybe 10 or so percent and then either turn it off and charge it or leave it on and charge it just do not pull the plug on the charger until it is at 100%.

This.

Full battery cycles are not good for long term life of Li ion batteries.

Also, its unlikely, but occasionally happens where discharging the battery to shutoff will render the battery unable to take a charge. The safety circuit on the battery is supposed to prevent this, but its not failsafe. I've seen more than a few reports on previous HTC devices where this happened. And since the battery on the One X is not easily replaced, the result can be disastrous.

The battery meters on phones are not very accurate in the best of circumstances. No need to drain to shutoff, 10 or 20% is fine. No value added to draining to shutoff, and the consequences can be very bad.

Drain to 10% or even 20%, charge to full, repeat 2-3 times. This is done just to calibrate the battery meter on the phone. Its a misconception that you can somehow increase battery life by "conditioning" the battery. But modern Li ion batteries do not suffer from memory effects, and conditioning only works for older tech NiCad batteries.

I do the same thing for all of my phones.

1. Activate and mess the heck out of it until it dies completely.
2. Charge it up to 100%
3. Mess the heck out of it again until it dies completely.
4. Charge it up to 100%
5. Mess the heck out of it again until it dies completely.
6. Charge it up to 100%

Then use it normally

Mine came dead! it didnt even turn on. so I'm charging it now

That stinks. It must have been on in the box like that other xda member on here claimed

Mine came with 1% battery so I just turned it back off and now I'm charging it up, i think the led will turn green when it's ready

How do you tell if the phone is charged to 100% while off?

While on, my battery percentage doesn't seem to go past 99%. Is that correct or is this last 1% just taking a very long time?

Update: NVM last 1% just took forever. LED does turn green when fully charged.
