Who cares, the load on my phone is quite intense, although adjusting the screen auto brightness in the room works by about 10%. on the depleted native battery (1700mAh when charging), it was from 2:50 to 3:30 hours of screen operation when the smartphone was working from 8 to 16:00 approximately.
new battery, 2960 measured while charging, from 4 to 4:30 hours of screen operation from 8 to 23:00. There is no drawdown% charge in the cold
If you discharge it indoors in a Wi-Fi network (Internet surfing), then it can be up to 6.5 hours of screen in half a day.
Also, if the smartphone is used very intensively, then you can get 5 hours of the screen when using cellular communication and wifi in half in half from 8 to 16:00.
A completely new smartphone showed me from 5 to 5.5 hours of screen operation from 8 to 23, but with a fixed brightness of 20 or 30 percent and firmware on a 6m android. Also then, my average memory load was 3 / 6GB, and now 4 / 6GB.

Axa__85,
The native battery showed the same measurement. As for the return - the determination of the remaining charge on the new battery probably works for me. 0 after a full charge, except for the first time, it shows at a voltage of 3.6v. If I did not know this and judged only by discharge, I would say that the battery is not a real capacity.
The calibration of the remainder needs to be redone, but has not yet managed.

The battery came, measured, discharged to zero and noticed on the switched off device.

tutunder,
My measurement of capacity shows from 1800 to 1900 mAh, the phone received in April 2017. For comparison, the iPhone 6 plus battery showed 1700mAh (with the initial 2900 with something) after 2.5 years of operation. So the battery as a whole is not bad, but not the most resourceful.

On Ali, an x-longer battery for the bug has now appeared, it costs more, about $ 14, as I will also unsubscribe.

Did anyone buy through lightinthebox? Did you pay extra customs clearance insurance? The delivery price there is suspiciously reminiscent of the amount for customs clearance from 100000r, which at the moment the projector is approximately worth without services for mediation. Since there is payment by paypal, then in theory shipment insurance is also not needed. Without these additional services, the price with a coupon is 119,000.

On Ali, I agreed to help Yilia Yi. But as I understood from her answer, customs is my problem. According to preliminary estimates, the price will be 110,000-120,000, depending on the issue with customs. At the same time a question. If you buy through Ali, can you use coupons for such purchases? How is this formalized through Ali? How to buy a left Lot for this amount or a bank transfer to this seller on parole? In case of theft or damage upon delivery, is the product insured?

And if someone asks why, if the 0.47 inch matrix has lower optical resolution, then it is used in 4k projectors with a shift, the answer will be like this. Due to the shift of Maritsa, a 4k projector requires 4 times faster micromirrors. Micromirrors of 0.65 inch matrix are larger, heavier, respectively slower. It is difficult to accelerate them with high voltage, so that they are affected by a 4 times greater electrostatic repulsion in physics, since everything works at the limit for a given yield of products. Most likely, during acceleration, some mirrors will begin to fail and there will be a problem of broken matrices in a given period of service. As a result, we were given a choice between an image with a higher optical resolution and an overlay of 4 images with a shift with a smaller optical resolution relative to the first. According to reviews, both the first and second options turned out to be clearer than xiaomi, but when comparing between them, what clearer the answer is not obvious to me. But at 1080p, the picture should be just lune. Including due to better contrast.

Due to diffraction by micron-sized mirrors with the same cost optics, the image will be sharper on a 0.65 inch matrix. Diffraction is the deviation of the propagation of rays from the laws of hermetic optics, and the smaller the diameter of the initially parallel beam, which depends on the size of the micromirror, the higher the divergence. Correcting this in the complex aspherical output optics of short-focus projects is very difficult or impossible, in principle, I do not think anything reasonable for the matrix with a shift. Even stupidly 2 million small microlenses are not suitable due to the shift of the matrix. Therefore, the usual lune in terms of optical resolution is preferable.

And someone in Moscow sells xgimi lune regular, not 4k? Or who better to buy in China? Through which intermediary / which seller to ask on Ali? Where does the price come with lower delivery at reasonable risks and what about customs?

al_mayorov,
I would like to know the results. When cooling, it starts to show a decrease in charge on the indicator, when it returns to heat, it returns at the same time. But also the phone can be cut down at 20-25 percent in the cold. As an exit, I keep a charge of at least 50 before going out or while still warm I connect to the power bank.

al_mayorov,
what I saw from brands like ykaiserin or wzvv is a typical non-name that is pasted with a sticker to sell at a higher price. sales of such batteries are minimal, there are no reviews with measurements, lots when you receive bad reviews are simply deleted. My forecast for these batteries is about 1500mAh. There is experience with pantech batteries, which invariably turn out to be 1000-1500 mAh instead of 2100 mAh. but there at least the case did not have to be disassembled to find out. If someone wants to experiment, I don’t immediately advise anyone unknown to Chinese manufacturers. If the batteries are sold in pairs, I also don’t recommend it, the manufacturer is hinting, there was experience too. The most balcony batteries. In the case of panthech, even 1000 mAh was not recruited. It remains a pseudo-original, but cheap and with delivery. I believe that this is the original after the reviews, since the price of shipping $ 11 is on the verge. According to my estimates, the original 12 dollars should be in wholesale + 3 dollars delivery. I would like to know exactly about the last option, maybe I'm wrong. I am reluctant to experiment myself, since my battery is not so bad, and I do not want to assemble-disassemble the case if the experiment fails several times.
And I will add that when I changed the glass on the camera to glass from xiaomi redmi notes, I saw the original for sale, if I'm not mistaken, 12 bucks. This makes me think that there are no original batteries on Ali.

al_mayorov,
What the original looks like, I see. The question is which seller on Ali can I buy it from? The Chinese have the peculiarity of cheating with batteries for rare phones and the purchased battery may turn out to be worse than the one I have now. Even the appearance of the lot on the seller’s page does not guarantee anything without measuring the capacity. There are no intelligible reviews on Ali.

Has anyone changed the battery? Is there an original on Ali, which when run by a tester gives 3000mAh?

EugeneDark, 1.5 years, since the first Chinese glass with ali turned out to be balcony, and from normal brands by the beginning of the summer of 17th there was nothing. There are scratches, but I’ll rather say that the screen is practically not scratched, since there are only about 10 pieces, no more than a cm long, during this time formed.

I would add that it is worth warming up the phone with a charged 10 percent battery, otherwise it doesn’t matter. I saw bloated batteries and now I have a phobia of this.

Iuriius,
After the news about autonomy, I already started looking at the mix 2s, I also did not like the screen. And the mixed 8/256 fell to $ 500.

ddv-79,
itvideo or something else? Here is a plus, despite the name, without a plus I can not find.
