Samsung has confirmed a problem with the battery in the Galaxy Note 7. It promises to exchange equipment [UPDATE] –

same time, information that Samsung provides mobile replacement when replacing phones are not confirmed.

The reason for the decision of Samsung are serious problems with the batteries. A few days ago the media reported from South Korea, with few serious incidents involving the battery in the Galaxy Note 7 – had they explode or ignite while charging.

Devices, which already hit the sales would be temporarily detained in warehouses. A spokesman for the Korean giant said in an interview with Reuters that smartphones require “certain quality tests.”

Samsung issued an official statement to the effect that until September 1 in the world there were 35 cases related damage battery. It is not much considering the amount of devices sold counted in the millions. Korean giant decided, however, to stop the sales and launch a global program to replace all sold to date Galaxy note 7 new ones.

It is worth noting that Samsung still determine the detailed cause of the problems. Bearing in mind the satisfaction and safety of consumers intend, however, within a few weeks to replace potentially faulty device.

What to do Polish consumers?

Press Office Samsung published a message that explains what they should do, persons who acquired already Galaxy Note 7.

customers who bought Note 7 in Poland, contact an authorized service center Samsung mobile phones (full list of services can be found at or contact the hotline phone number 0,801,672,678 or +48 22 607 93 33. the devices will be subjected to a thorough verification and returned with proven battery or the customer will receive a new copy in the case of identification of the defect. The entire process can take up to several weeks.

We are aware of the disadvantages which are inherent to this situation, but we want to be sure that Samsung provides its customers with products of the highest quality. We work closely with our partners to ensure that the process of replacing the devices will be as convenient and efficient as possible

Too early for diagnosing

The causes of the problems may be a few – there is no reason to prejudge the batteries explode due to a manufacturing defect. Australian reminds that the responsibility for the problems may be a new port type USB-C, namely cable. According to Google it was he who caused the fire tablet Pixel C.

Korean media say about several cases of damage Note 7, but all they could find an explanation in the improper use of the device. Bryan Ma, an expert research company IDG, said that Samsung may determine its decision respects by image.

must nip in the bud doubt. The last thing they need are memes rambling through the internet, mocking Samsung and associating it with a battery explosions or injuries – he says. Ma.

Please note that Samsung may withdraw only part of the device, as it produces millions of them. Reports say a few individual incidents.

Is the battery may just explode? We’re talking to an expert.

The comment to the situation we turned to a specialist.

Robert Kędzierski: Is the explosion of the battery, which reported media in the context smartphones, including Samsung, it is possible for each device? Are there any special circumstances necessary?

Marek Marcinek *: Let’s be precise, we are talking mainly about the popular today, lithium-ion batteries. Yes. Unfortunately, explosion or ignition is possible. Usually it comes to them as a result of unusual events such as the fall of your bike (see: recent incident cyclist featured in the press, after which it was necessary to graft skin) strike, as a consequence of breakage devices and such. Shorted cells causing ignition. This, however, are the issues of custom, extreme. Fork / knife used to eat food, but placed in a pocket during a trip can stick in the thigh during the fall. Example drastic, but adequate.

So it does not matter who produces the battery? What counts are the circumstances?

Exactly. Of course, you can analyze statistics and try to emerge most
emergency manufacturers. In a general sense, however, there is a kind of democracy here, because
theoretically the possibility of failure applies to any device with a battery-
manufacturing defects happen to the best manufacturers. The risk increases
use cheap, not necessarily compatible replacements for original batteries and chargers
or, for example. Exhibition of equipment to direct sunlight.

Battery manufacturers do not provide, that can happen to them something unexpected?

foresee. I batteries, and devices are adequately tested to
even in emergency situations there was nothing wrong with it.

So what could be the cause of several incidents Galaxy Note 7?

Until we know the real reason you absolutely can not prejudge the guilt Samsung. Generally, the ignition as a result of charging can occur from many causes: overload the battery (eg. Due to security flaws from overcharging, incompatibility of chargers). At stake is a defect in the control system battery (so-called. BMS – Battery Management System). There are also other causes, including structural defect batteries (eg. The defect separator), lack of adequate heat dissipation system. All this can lead to overheating and in extreme cases to the fire. In each device, each manufacturer. Several incidents no way prejudge.

So with confidence in our smartphones is not ticking bomb?

Lithium-ion batteries statistically belong to safer systems of accumulation of energy. Failures occurred known lead-acid batteries, some doubt regarding the safety or raise fuel cell systems powered by hydrogen. A explosions and tanks with conventional fuel is also still occur.
