Overheating smartphones? Best tips to manage and prevent.



Smartphones have become essential to modern life due to their versatility and usefulness. Smartphones have transformed how we live and work, making our lives more connected, productive, and convenient. Some of the main reasons are:


  1. Communication: Smartphones enable us to stay connected with others through phone calls, text messages, and social media apps. They have made communication more accessible and convenient than ever before.

  2. Information: Smartphones provide instant access to vast amounts of online information. They allow us to search for answers quickly, look up news and current events, and access educational resources.

  3. Productivity: Smartphones are powerful tools for productivity, allowing us to manage our schedules, send emails, and work on documents on the go. They can also provide access to productivity apps like to-do lists, calendars, and project management tools.

  4. Entertainment: Smartphones offer a range of entertainment options, from streaming video and music to playing games and reading books. They have become a primary source of entertainment for many people.

  5. Navigation: Smartphones have made getting around easier with built-in GPS and map apps. They can provide turn-by-turn directions and real-time traffic updates, making navigating unfamiliar areas easier.

Unsurprisingly, we want the best battery performance on our smartphone devices to allow us to continue using them without interruptions for everything important to us.


Smartphone Battery Technology




There are several different smartphone battery technologies in use today. The most common types of batteries used in smartphones are lithium-ion and lithium-polymer batteries.

Lithium-ion batteries are popular due to their high energy density, relatively low self-discharge rate, and long lifespan. These batteries use a liquid electrolyte to transfer ions between the anode and cathode and are generally safe when properly manufactured and used.


Overall, the trend in smartphone battery technology has been towards higher energy density, longer lifespan, and faster charging times. Manufacturers are continually researching and developing new materials and techniques to improve battery performance and address concerns around safety and environmental impact.


How we Test at ViserMark

At ViserMark, we perform a variety of testing to ensure that the battery is functioning properly and to determine how long it can last under different usage scenarios. Thanks to the test automation capabilities of viSer, we can test battery life using the smartphone under normal usage conditions, monitoring how long the battery lasts. This is done by setting up the phone to simulate typical usage (Day of Use), such as web browsing, video playback, voice calls, and other activities.




Testing Process


1) Device Calibration

Each device that arrives in our lab is strictly calibrated to ensure that all devices are tested with the same conditions, ensuring repeatability and consistency. The calibration includes fixing parameters like brightness levels, audio volume, and connectivity setups like Bluetooth, NFC, GPS etc). All devices are fully charged before starting the testing.



2) Environment Strict Conditions


As with the device calibrations at ViserMark lab, we follow a very strict protocol on external environmental conditions. All testing takes place on live network conditions to ensure we test closer to end users. Performing testing in the lab will never give a true picture of a device's battery life. We test on good network conditions. The network can greatly impact the smartphone battery life, and weak network conditions normally use more power from the device, impacting the battery life.


We also ensure the room ventilation in the lab is at a certain level, as this can impact the battery life performance.


3) Testing

Once the device and the environment are calibrated and checked, it's time to perform the testing. We use the test automation viSer to ensure all the testing is performed the same without any human error. viSer runs the Day Of Use scenario. The Day Of Use scenario includes several usages as the end user performs. Our team of experts created the scenario with input from several surveys on how people use their devices regularly and feedback from media and Mobile Network operators.





During the testing viSer monitors all activities and any abnormal battery behaviour. If the battery percentage drops rapidly or the device shuts down unexpectedly, this could indicate a problem with the battery. We also monitor the temperature to ensure there are no overheating issues.


All results from the testing are available in the SmartViser Analytics Studio, which allows

in-depth analysis of the results and behaviours.






Once the results review is completed and the scores are finalised, we can prepare the ViserMark labels and in-depth reviews.
