A rare and somewhat weird problem has begun to surface with the Galaxy A3 (2016), post the Android 7.0 Nougat update. Apparently, a large number of Galaxy A3 (2016) users are finding it impossible to get their device to take charge once the battery reaches 87% or so. Although the cause for this issue remains unknown, one thing which can be said for sure is the fact that this issue appeared only after Samsung updated the device to Android 7.0 Nougat.


The usual tricks as instructed by the Samsung care executives did not work either. Apparently, clearing the cache or even factory data resets are ineffective for some reason and that's a worrying fact if you own the handset. You can try charging the handset in Safe Mode, but that did not work either, as reported by many users. We are hopeful that Samsung will address the issue soon by releasing an OTA patch, but it remains to be seen when that happens. Stay tuned to YouMobile for more information on the subject.

Wireless charging is a ground breaking technology that lets you charge your devices without mingling with cables or faulty USB ports. Simply put your phone on a wireless charging surface and all will be taken care of. That comes with a negative element - while charging you can not use your phone.


Si-Ware Systems and Ossia have come up with a new system called Cota which can be used to charge compatible phones within a 30 foot radius. While devices can consume a maximum of 6 watts for charging, this system is capable of transferring 10 watts power. This is nowhere near the Quick Charge 2.0, but it does a pretty decent job considering all the factors. Thanks to the radio frequency technology - the device charging won't be affected negatively in case of minor obstructions.


This technology doesn't only apply to smartphone and wearable devices. Things like wireless keyboards can also be charged via this system without plugging in anything. The device will be charged till the time you are near the charger.


Although the effect of constantly charging the devices for 12 hours in day is yet to be found out, we all can agree that this is indeed a great step forward.

Battery life is usually number one on the list of concerns that users have when choosing a new mobile device. Battery technology has been slow to keep up with the devices that are with us all day long, and so manufacturers have had to take other routes larger devices for larger batteries, or faster charging. But, a new breakthrough with sound waves could let you leave your charger behind for good.

 

Researchers with Queen Mary University of London have teamed up with Nokia to build the first prototype smartphone that can be charged using only sound waves. QMUL's Dr. Joe Briscoe and Dr. Steve Dunn first came upon the idea last year when they noticed that playing music improved the performance of solar cells. From there, the team developed a nanogenerator capable of collecting energy from ambient sound. The key to the nanogenerator was zinc oxide, which can create voltage when it expands and contracts. Zinc oxide was formed into nanorods which could generate five volts of electricity, enough to charge a phone.

The team has already been able to cut costs of production for the nanogenerators, but the technology still needs time to mature and be built to scale. Ultimately though, it could mean that mobile devices of the future will be charged with the everyday sounds around you, like traffic, music, or even just talking. As the technology matures, it could extend battery life, or mean that you'll never have to plug in your phone again.
