9 Bad Cell Phone Battery Symptoms to Be Addressed Immediately
While it''s normal for phones to lose a few percentage points of battery charge quickly, a drop of 10% or more is a clear indication that your battery is failing. If you charge your phone until it is fully charged, but the battery life seems to run out quickly (2 hours or less) or if it shuts down, this may be another symptom that your battery is …
Chinese scientists design new fast-charging lithium-ion batteries
This new design can enable lithium-ion batteries to achieve reversibility when the cells are charged and discharged in a wide temperature range from minus 70 degrees Celsius to 60 degrees Celsius. The lithium-ion batteries can also be charged and discharged within just 10 minutes at room temperature, according to the study published …
While the video in question is misleading, there is evidence to suggest that cell phones may emit varying degrees of electromagnetic waves depending on battery charge and how the phone is being used.

A Chinese startup claims to have developed a new battery that could power smartphones for 50 years without the need for charging. Beijing-based Betavolt said its nuclear battery is the first in the world to realise the miniaturisation of atomic energy, placing 63 nuclear isotopes into a module smaller than a coin, reads an Independent article.
That means you use them up and then they die. It''s the circle of life. Li-ion batteries primarily degrade over charge cycles—according to Apple, an iPhone retains up to 80 percent of its original capacity after 500 complete cycles (from 100 to zero percent charge).After that, the battery meter would still read 100% after a full charge—but it would only last 80 percent …
