We have all been in that position where our laptop battery starts to malfunction; that moment when a 10-hour battery life device depreciates to serving you for one hour or less.

Insight from the Research and Development Unit of Yudala, Nigeria’s fastest growing composite e-commerce outfit, shows that while laptop batteries often depreciate with constant use over time, misuse or wrong usage often leads to this happening within a short period of time and at a time when you should still be deriving optimum utility from your laptop battery.

Laptop batteries are usually made from lithium-ion: a lightweight, high-power battery often used in computers and mobile phones.

Lithium-ion batteries come in various shapes, although a flat rectangle is most common in smartphones.

It is lighter than the nickel cadmium battery and the nickel metal-hydride battery, thus accounting for its lightweight nature. Lithium-ion batteries work by the movement of lithium ions through a membrane and are clearly different from lithium batteries.

Whereas lithium batteries contain lithium metal and are not rechargeable, lithium-ion batteries do not contain lithium metal and are rechargeable.

However, lithium-ion batteries do not last forever. Each lithium-ion battery will have an average of 600 charge cycles and will work optimally for about 4-5 years without a drastic depreciation on battery life.

Hence, your laptop battery should serve you well for at least 3-4 years depending on how frequently you use the device and recharge the battery.

Research shows that frequent travelers only get a couple of years out of their laptop battery because they tend to charge intermittently and keep their laptop unplugged when on the move which kills the laptop battery faster.

To help you get maximum life out of your laptop battery, the following tips from Yudala will go a long way in helping you save the cost of investing in a new battery at short intervals:

Avoid Putting Your Laptop On Soft Surfaces

It is easy to place your laptop on your thighs or bed while working at home or during your rest time. Many of us are guilty of this.

However, if you need your battery to last long or have a stronger life span, it is advisable to place the device on hard surfaces such as tables or desks in order to avoid over-heating.

Research has shown that heat is one of the biggest obstacles to your battery’s longevity because your laptop fan can’t circulate air properly when your laptop is placed on a soft surface.

Be Careful How You Store Your Laptop Battery

This cannot be over-emphasized. It is advisable to store your laptop in a cool place with less heat. This tip is directed especially at people who keep their laptops in their cars where it can get really hot when it’s sunny. Laptop batteries do not work well with heat and might stop working if exposed to excessive humidity. Research shows that, if a stored battery is not charged, it starts to lose it energy and might get damaged. Also, for travelers who leave their laptops behind, it is advisable to store your battery with a 40 – 60% charge instead of a full charge. Study shows that fully charged batteries depreciate faster than half-charged batteries.

Do Not Leave Your Laptop Dead Before Plugging It In

There is said to be a problem called ‘battery memory’ which, cause batteries to ‘forget’ their full charge capacity and start charging at lower levels; charging to 100% and discharging to 0%.

Current research indicates that this problem doesn’t exist anymore and we have the modern lithium-ion battery to thank for that. It is important to point out that the problem here is not over-charging your laptop, which makes us believe that letting your battery charge more than 100 percent will make the battery wear out faster.

A research study by Battery University shows that, modern devices are designed to stop charging at 100 per cent hence, keeping them plugged in doesn’t impact the battery’s lifespan.

However, a lot of us wait until our laptop dies before we plug it in, which isn’t good for our battery. You should avoid letting your battery drain and discharge below 20 per cent, else, it would reduce the charging capacity of your battery.

Show Your Laptop Some Love

This starts with your battery. Your battery is the powerhouse of your laptop. Abandoning your laptop battery and just letting it do its job without paying much attention to it won’t cut it.

Make sure to take care of the battery contact points; the battery contact connects the battery to the laptop.

If the contact point gets dirty or damaged, it may reduce or disrupt the flow of power to the laptop.  If you have a removable battery, you can carefully wipe your battery with a soft cloth to get rid of dust. However, you have nothing to worry about if your laptop battery is sealed.

Update Your Laptop

As underrated as this may sound, an outdated hardware may reduce the performance of your laptop thereby affecting the laptop battery.

The cells in laptop batteries degrade over time, and it is totally normal for old laptop batteries to hold charge less than an hour.

Current laptops can achieve up to 10 hours of standard usage because of the software that comes with the perk of a new laptop. Henceforth, upgrading your laptop hardware will significantly improve your laptop battery life.

Data Privacy Ignorance Threatens National Security –  DKIPPI

Data Knowledge and Information Privacy Protection Initiative (DKIPPI) has warned that widespread ignorance of data privacy practices is exposing Nigeria to serious national security and economic risks amid a rise in ransomware attacks.

Data Privacy Ignorance Threatens National Security -  DKIPPI 

Tokunbo Smith, president of DKIPPI, warned on Tuesday in Lagos, that  the increasing frequency of ransomware incidents underscores the dangers of weak data protection systems across organisations and institutions.

He described ransomware attacks as a growing threat in which hackers infiltrate systems, demand payments and threaten to leak sensitive data.

Mr Smith said, “The cost of ignorance in data privacy is not just what you lose. It is what you expose. Data privacy has evolved beyond a technical concern to a critical governance and national development issue requiring urgent attention. Ransomware is no longer just cybercrime; it is economic warfare and a governance issue.”

Mr Smith urged both public and private sector leaders to adopt proactive and comprehensive data protection frameworks to safeguard sensitive information and strengthen institutional resilience.

He also called on government at all levels to go beyond punitive responses and implement stronger regulations, enforcement mechanisms, and national cyber resilience strategies.

According to him, DKIPPI will soon release a policy advocacy paper outlining the key risks associated with poor data protection practices.

He said the paper would highlight financial losses, institutional inefficiencies, and threats to national security, while recommending urgent reforms to procurement processes, compliance systems, and governance structures.

Mr Smith added that addressing data privacy gaps was critical to protecting Nigeria’s digital economy and restoring trust in its institutions.

Angst as FG Drops $32.8m Fine on Meta for Data Breach

Decision to cancel the $32.8 million fine previously imposed on Meta for alleged data privacy violations was taken as far back as October 30, 2025.

Angst as FG Drops $32.8m Fine on Meta for Data Breach

The development has raised concerns over the country’s approach to data protection enforcement and regulatory transparency.

This followed a confidential, out-of-court settlement singed by Nigerian Data Protection Commission (NDPC) with Meta, effectively waiving the fine imposed earlier that year.

This deal, sanctioned by a Federal High Court, resolved disputes over behavioural advertising and user data transfers without Meta paying the penalty.

Recall that the NDPC claimed that it launched investigation in September 2023 that examined Meta’s handling of personal data from more than 60 million Nigerian users.

The NDPC had accused Meta of several breaches, including the absence of explicit consent for behavioural advertising, unauthorised cross-border data transfers, the collection of data from non-users, and the deployment of algorithms that could expose users to financial and health risks.

At the time, the regulator described the penalty as part of efforts to strengthen digital rights protections in Africa’s most populous country, aligning Nigeria with global enforcement trends in the United States, United Kingdom, and European Union, where Meta and other major technology firms have faced multibillion-dollar fines for similar violations.

However, documents from a subsequent settlement indicate that Nigeria reversed its position in October 2025.

Under the agreement, Meta was absolved of the $32.8 million penalty and required only to cover legal fees incurred by the government during court proceedings challenging the NDPC’s final orders.

The settlement was signed on 30 October 2025 and later validated by the Federal High Court in Abuja on 3 November 2025.

Despite this judicial confirmation, the terms of the agreement were not made public at the time, and only recently emerged through disclosed documentation.

The development has triggered questions about transparency in regulatory enforcement, particularly given the scale of the initial allegations and the number of affected users.

Iliya-Ezekiel Ndatse, data protection lawyer, said the outcome weakens regulatory deterrence.

“Removing penalties after such findings reduces the effectiveness of enforcement actions and weakens the credibility of compliance obligations,” he noted.

The case has also drawn comparisons with Nigeria’s previous dispute involving Twitter, now rebranded as X, which was banned in 2021 before the two parties reached a negotiated resolution.

Kaspersky Discovers Vulnerability in Qualcomm Snapdragon Chips that can Lead to Data Loss & Device Compromise

Published

Kaspersky ICS CERT discovered a hardware-level vulnerability affecting Qualcomm chipsets that are widely used in a range of consumer and industrial devices, including smartphones and tablets, car components, IoT devices and more.

The vulnerability resides in the BootROM – firmware embedded at the hardware level. Attackers could potentially get access to any data stored on the device or device sensors like camera and microphone, implement complicated attack scenarios and in some circumstances get full control of the device. The results of the research were presented at Black Hat Asia 2026.

The vulnerability affects Qualcomm MDM9x07, MDM9x45, MDM9x65, MSM8909, MSM8916, MSM8952 and SDX50 series and was reported to Qualcomm in March 2025. Qualcomm formally acknowledged the vulnerability in April 2025. It has been assigned a CVE-2026-25262. Other Qualcomm-based chips may be affected as well.

Kaspersky researchers explored the Sahara protocol, a low-level communication system used when a Qualcomm chip enters Emergency Download Mode (EDL) – a special recovery mode designed for repairing or restoring smartphones or other devices. Sahara acts as the first step that allows a computer to connect to the device and load software before the operating system on the device starts.

Kaspersky demonstrated that a security flaw in this process could allow an attacker with physical access to the target device to bypass key security protections in the chip, compromise the secure boot chain and, in some cases, deploy malicious applications and backdoors to the chip’s Application Processor, thus fully compromising the entire device.

For example, in cases when the target device is a smartphone or a tablet, the attacker can potentially get access to entered user passwords, and subsequently this opens further access to multiple types of sensitive user data, such as files, contacts, location, access to the devices’ camera and microphone, etc.

A potential attacker only needs a few minutes of physical access to a device to compromise it. Therefore, if a smartphone has been sent for repair or left unattended for a short time, one can no longer be sure it is not infected. Researchers warn that the threat extends beyond end-user scenarios to include potential compromise during the supply chain phase.

“Vulnerabilities like this may allow attackers to deploy malware that is difficult to detect and remove. In practice, this could enable covert data collection or influence device behaviour over extended periods of time.

“While a reboot might seem like an effective way to remove such malware, it cannot always be relied upon: compromised systems may simulate a reboot without actually resetting. In such cases, only a complete loss of power – including battery depletion – guarantees a clean restart,” comments Sergey Anufrienko, security expert at Kaspersky ICS CERT.

Kaspersky advises organisations and individual users to exercise strict physical security control over devices including at the supply, maintenance and decommissioning phases. A reboot of the device by cutting off the power supply to the affected chip (if available) or full battery discharge may help to get rid of the malware if it was installed.
