The problem with the charging BV6000s MT6735A

Postby Damned_Noiz » Fri Jun 16, 2017 8:05 am

That when charging from devices such as powerbank, solar panel or charger from other manufacturers the total charging current is 500 mAh and charging current of 300 mAh + discharge current of 200 - 250 mAh. When charging from the mains, the total charge current does not exceed 1000 mAh and the charge rate 700 mAh + discharge current of 250 - 300 mAh.
Shortcomings:
1. Not correctly-written software to charge controller (not written for a specific model, and taken a ready-made template without changes) in a particular case: not specified design capacity of the installed battery (indicated 1000 mAh is 4200 mAh).
2. The charge controller does not determine the charger is connected to transfer data or just for charging which will not charge more than 500 mAh.
3. The maximum total charge current which is necessary to pass the controller needs to be 2400 mAh to have the actual charge current of 2000 mAh. (the total charging current of 2400 mA and charge current of 2000 mAh + discharge current of 200 - 400 mAh). Please inform the company which is developing software for your products and let them fix the problem.

The simplest solution is to add a menu item (when connecting a network charger) that would force the charge controller to accept a current of up to 2400 mAh (2.4A) If the installed board allows. With a warning that you can not actively charge and use a smartphone (play games and watch videos), and also that the smartphone when charging it is desirable to lay down on the table with the back side up. Because there can be unpleasant consequences ....

当充电的设备,例如移,太阳能电池板充电器或其他制造商的总充电电流为500毫安时和充电电流的300毫+排放当前的200-250毫安时。 当充电电源,总费用目前的不超过1000马和费率700马+放电电流的250-300毫安时。
不足之处:
1. 不正确地编写的软件,以充电控制器(不写一特定模型,和所采取的一个现成的模板,没有更改)在特定情况:不指定的设计能力已安装的电池(指出1000毫是4200mAh)。
2. 充电控制器不确定的充电器相连接数据传输,或只是为了充电,这将不收取超过500毫安时。
3. 总的最大充电电流必须通过控制器需要2400毫安时到有实际的充电电流的2000年mAh。 (总充电电流的2400马和充电电流的2000年马+排放当前的200-400mAh)。 请提前通知该公司,这是发展软件产品和让他们解决问题。 谢谢你

最简单的解决办法是添加一个单项目(当的连接的网络充电器),能力充电控制器接受目前可达2400马(2.4)如果安装局允许的。 有预警,你不能积极地收取和使用智能手机(玩游戏,及观看的影片),以及智能手机充电时它希望躺在桌后面。 因为有可能是不愉快的后果....

Firmware V01_20160929. The expected solution to the problem. The problem is not isolated. It's just not noticeable because of the large battery capacity, enough to evening, and for 8-9 hours (at night) he will charge to 100%. No matter whether it is fixed in the sixth or seventh version of Android the main thing that was fixed.
Thank you.

Same thing here, battery used to charge from empty to 100% in few hours, and all the sudden it takes at least 12 hrs ! Has a solution or fix been found ?? Regards,

The issue was raised more than once. To solve the problem there, as well as an explanation of why this is happening. This problem occurs as BV6000\BV6000s as processor MT6375A and МТ6737Т (and new smartphone out of the box). Just counted about 10 reported cases and the number is growing.

Charge test through a homemade cable (Ethernet 2 pairs), two wires per +5V and GND contacts to exclude the wrong definition and greater bandwidth.

BV6000\s does not support charging current of 2A.
p.s In my case, the replacement cable does not help. Most likely it was a factory defect or error in the software.

You can only use the blackview official USB charger to charge the blackview phones.

To offer use only the original charger and cable of a smartphone (where you intend to use it in places where no electricity) really stupid.
