many are called few are chosen when it comes to battery and phones,in the case of smart phones dey're not.let's cut the jingle short. I no to some its no news, this happened as a mistake one day. I was watching film with my roommate n charging my phone when the battery went down so he decided to hibernate his system and mistakenly put it to sleep n funny enough my phone was still charging with my happiness n surprise I ran to my system to try it but it didn't work then I discovered dat it varies from system to system. although was disappointed but av been using my friends system ever since to beat phcn. less I forget my laptop is HP pavilion g6 series core i3 and my friends own is dell Nseries core i3.
