Tablet Evercoss AT1C, Baru Seminggu Langsung Rawat Inap

Treq 3G Turbo Plus
Comment 1:
Kelemahan dari Tablet Treq 3G Turbo Plus terletak pada ketahanan baterai yang masih diragukan. Juga kualitas colokan di power DC yang agak longgar dan sering rusak.
Comment 2:
TREQ jelek betul jaringannya, cepat panas,
kamera 5MP tapi lebih terang kamera yang 1MP.
baru 3 hari beli tapi dah menyesal bangat,

Baterai Tablet
Jangan mengisi baterai lebih dari sekali atau dua kali 'life cycle' per hari. Menggunakan baterai tablet sampai habis kapasitasnya/ sampai muncul peringatan/notifikasi dan melakukan pengisian hingga full menyumbang kerusakan baterai. Karena usia baterai juga dihitung berdasarkan 'life cycle'. 1 life cycle = 1x pengisian sampai penuh (full charging) + 1x penggunaan sampai habis (full discharging).  Umur usia keawetan baterai lithum rata-rata 500 life cycle/ tahun, dengan asumsi kita melakukan charging-discharging 1x per hari maka usia baterai adalah 500 dibagi 365hari. Jika kita cas 2x sehari jelas baterai tablet jadi lebih boros.
Solusi yang baik berdasar panduan penggunaan baterai lithium polymer dari perusahaan 'Apple' yang memproduksi iPhone dan iPad adalah dengan mengisi ulang baterai setelah periode penggunakan berjalan sebelum mencapai 50 % dari kapasitas untuk menghindari penghitungan 1 x life cycle. Itulah mengapa pada tablet lebih baik melakukan charging saat off atau dalam kondisi mati untuk menghindari penghitungan life cycle.
Jadi berbeda dengan type baterai nikel (yang digunakan pada handphone tahun '90an) yang lebih baik dicas saat sudah kosong, kini pada type baterai tablet berlaku kebalikannya, akan lebih baik jika dicharge sebelum benar-benar habis/ kosong.
