May i just request you, please, to assess how long it takes to your battery to loose 1% when surfing safari even when looking at this thread? I would like to understand whether or not mine, which takes 3-4ish min for 1 % under wifi connection, is sick or not. May you also check with 4g + lte, please,that traduces into 1% every 2-3 min ish? Thanks for your kind help. For info: app background refresh off and brightness at 40 to 50. Cheers.
