Battery question

[Flast]

Hello, I have a doubt that I have to clarify as soon as possible. I bought a Huawei p8 lite 2017 yesterday and at the very first start I noticed that the battery was totally empty. Isn't that strange? An absolutely new phone should have even a small percentage of charge. But this is not my case. Is it a signs of a defective battery? sorry for bad english e thanks to everyone who can answer this question!

Hello there!
Not really sure, but I would think there should be enough to boot up the device and then maybe get a "low battery" warning.

I really wouldn't fret too much about it now, just charge it up, give it several days of use/discharging/charging etc, then judge the battery.

I think you'll be fine to be honest

First thing to do with a new phone (even if new to you) is to charge it when it's off. I have bought replacement batteries and found some of them completely dead on arrival, but once fully charged they will work flawlessly.

Well yeah, when I tried to boot up the device for the first time, the "low battery" icon appeared and then it shutted down in a sec. It wasn't totally unable to turning on, but the battery was too low to start up. I will keep an eye on the battery to make sure there isn't any strange behavior of the battery. The problem is that the warranty of the product only last 7 days, and 2 of them already passed. Thanks a lot for you answer, I really appreciate it and I'll do as you suggest!

So according to you it's something that sometimes happens, good. But nowadays smartphones don't have removable batteries anymore.. and it's a huge problem if they die.

I also have a new non-removable battery that has no power left when it arrived, it's a replacement for my HTC 10 Bolt. While it's a brand-new battery, the production date reads 2016 *something* so it's normal that there is nothing left in it.

In your case, the battery is installed in the phone, so it has 100 times more chance to be used than spare batteries.

No strange behavoir or battery loss until now. So I think everything's ok, as you sad. Thank you very much

Yeah, it should be fine now that you charged it up again. The thing is, that model was first released in 2015 so if it was sitting on a shelf in storage somewhere it's not surprising for the battery to be drained like that. As long was the phone was powered off, an unused battery should hold a usable charge for months, well over a year. But three years is pushing the limit. Typically you don't want to continuously drain your battery down to single digits, doing so will shorten it's overall life, and it's not a big deal for it to happen every so often. Just don't do that regularly.
Those who work with smartphone batteries at a technical level recommend keeping your battery in its 25-85% range and that will extend its overall use life. Of course most of us have a lot more going on in our lives so that's not really practical to spend so much time always watching what the battery level numbers are, but it is at least a guideline to keep in mind.

My model isn't the standard p8 lite released in 2015, it is the 2017 version. It was released on January 2017, if I'm not wrong. Anyway what you say is absolutely correct. The one I bought may have been available on the market for a long time. This could explain why the battery was empty. Thank you for the link about how treat batteries and obviously for your answer.
I must admit that this forum is a very good place. It's very useful and here I found kindness and competence. I hope to be helpful to those who need it too haha

Greetings to everyone from Italy!

Ahh, I stand corrected. Now I do see a lot of stuff online for the 2017 P8.
Odd that the battery was initially drained like that, but let's hope all will be well now that you've charged it up and things appear to be working out OK.
