Aura HD Battery life

supermaily · 10-17-2013, 01:07 PM

I've new Aura HD and one year old Kindle NT. Today, after two weeks, my Aura's battery has died (after one warring!). In reading life I have 16 hours. Mainly I have wifi and light turned off. And reader has never been turned off, only in sleep mode. Charging and discharging process isn't linear, eg. after 1 hour (from 2 hours) charging I have still 46% battery. My old Kindle can handle in very high load two weeks about(without wifi).

Is it correct?
Should I turn off reader?
Do you have any tips about energy saving?

Did you fully charge the Aura HD before you started reading? Mine arrived from the factory about 40% charged. It also took several charge/discharge cycles before the meter/% battery display started to correctly indicate battery condition.

I generally charge my Aura HD about once per month when the 10% charge warning pops up.

Regards,
David

Also other people have noted that the charge percentage shown on the Sleep display tends to stall during charging, and then suddenly update to a higher value when you disconnect.

I'm one of those; twice it's hung at 47% and once strangely at 53%. All three times I unplugged it, turned it on, plugged it back in and a few minutes later it was at 100%.

I haven't noticed how my battery is. But I've never had any problems with it. I probably charge the battery every 2 or 3 weeks.

yes I've noticed the % stalling while charging, too.

As for the battery, if you only read, I've had circa 40 hours of use (meaning, those in the reading stats) with wifi off and not shutting it but simple sleep and with light between 7 and 37, depending on day and night.
But, if I start to play a bit (solitaire, sudoku, whatever) the battery goes down much faster.
Depending on that I've had to charge it every 2-3 weeks.
