  • Am I willing to pay the price to support ethical hardware?
    The planned obsolescence is even worse with tablets and smartphones, whose components are all soldered down. The last tablet with a removable battery was the Dell Venue 11 Pro (Haswell version) announced in October 2013, but it was an expensive Windows device that cost as much as a mid-range laptop. The last Android tablet with a removable battery was the Samsung Galaxy Note 10.1 (GT-N8000 series), released in August 2012. It is still possible to find mid-range smartphones with removable batteries. Last year the only high end phones with removable batteries were the LG G5 and V20, but even LG has given up on the idea of making phones that will last longer than 2 years once the battery starts to degrade after roughly 500 full charge and discharge cycles. Every flagship phone introduced in 2017 now has its battery sealed in the case. According to the gmsarena.com database, the number of new smartphone models with non-replaceable batteries grew from 1.9% in 2011 to 26.7% in 2014, and now to 90.3% in 2017. It is highly likely that not a single model of smartphone introduced next year will have a replaceable battery.
