Samsung Galaxy Note 8 battery crisis

Samsung has been hit by another battery issue.

Galaxy Note 8 owners have reported that they are unable to charge or turn on their handsets after the batteries ran dry.

Samsung has confirmed the issue, saying it has received ‘a very limited number of reports which could be associated with the power management circuit.’

WHAT YOU CAN DO 

Some users have tried a method called ‘stack charging’ to bring their phone back to life. 

By plugging your charger in and out of your phone for 10 to 15 seconds at a time about 30 seconds apart, you could generate enough energy after about 20 minutes or 100 attempts to get your phone restarted

 

However, it appears the issue is affecting only a small number of users.  

Samsung advises affected users to get warranty replacements for their Note 8.

According to a Samsung spokesperson, ‘we are unable to comment further until we obtain more specific information from the phone,’ according to Engadget.

‘Any consumers with questions about their device should contact us directly at 1-800-SAMSUNG so that we can help them.’

The new Galaxy Note 8, unveiled in New York, sports a dual-lens camera, animated messages, expanded note-taking – and a lower battery capacity.

The South Korean tech giant is no longer trying to squeeze more battery power into each phone, it said.

2016’s Note 7 had to be recalled after dozens spontaneously caught fire because of defective batteries.

Samsung previously blamed two separate battery issues for the fires that hit its flagship Galaxy Note 7 device in 2016 year, as it sought to draw a line under the humiliating recall.

The world’s biggest smartphone maker was forced to discontinue the smartphone, originally intended to compete with Apple’s iPhone, after a chaotic recall that saw replacement devices also catching fire.

The fiasco cost the South Korean company $5.3 billion (£4.2 billion) in lost profit and reputational damage.

It came during a torrid period when it has also been embroiled in a corruption scandal that has seen President Park Geun-Hye impeached.

Internal and independent investigations ‘concluded that batteries were found to be the cause of the Note 7 incidents’, Samsung said in a statement.

‘We sincerely apologise for the discomfort and concern we have caused to our customers,’ Koh Dong-Jin, the head of its mobile business, said bowing before hundreds of reporters and cameramen at a press conference in Seoul.

The first issue was that the battery components in the Galaxy Note 7 did not fit in the battery’s casing.

This caused the battery cell’s upper right corner to be crimped by the casing.

The second round affected the devices sent to replace the original faulty phones.

HOW DO RECHARGEABLE BATTERIES WORK?  

Conventional lithium ion batteries contain two electrodes – one made from lithium (cathode) and one from carbon (anode) – submerged in a liquid or paste called an electrolyte.

When the battery is charge, electrons that were attached to the ions flow through a circuit which then powers the device. 

When a battery is being charged up, ions flow from the lithium electrode to the carbon one. 

When a battery is discharging, the ions flow the other way.

A different study has found that using potassium ions inside batteries increases electrical conductivity, helping the lithium ions move faster.

Adding these ions makes the batteries recharge faster.
