Hello,
I´m a little bit confused.
I have waited for the Newton because a main advantage is a higher battery life and now it seems that a Newton has even a shorter battery life that an iPro??!!
Ibikesport promises 160 hours.
Now I read:
1.
160 hours was an engineering estimate
Upps, does that mean that iBikesports promised 160 hours but they didn´t any realistic test? (When GM brings a new car on the market, I expect that they test it before and know exactly the maximum speed and don´t tell me “an engineering estimate”!)
2.
We see a discharge rate of about 2.5% per hour.
A discharge rate of 2,5% per hour means a theoretical maximum of 40 hours continues use.
I suppose the battery is a lithium battery. If yes there should be always a rest capacity of 10 – 20% otherwise the life time decreases (> 32 – 36 hours….).
3.
When the Newton is "off" it still uses some power...
I ride only 3 – 5 time per week so I suppose that 32 – 36 hours are not realistic, because in the meantime the Newton needs a little bit power too.

Fully charged battery lasted approximately 16 hours, no where near the 160 stated
and
I am having the same issue with battery depletion with my Newton+. My Newton+ does not hold anywhere near the 160 hours promised. I charged the unit to 100% one evening, turned the unit off, and checked the battery in the morning before a long ride - it was down to 93%. After only two rides 2-3 hours and 4-5 days, the unit was down to 37%.
It seems at the moment the battery live is only about 10% of the promised value.
5.
Since I happen to download my rides daily, my battery level never drops below 90%
Fine, but I only want to know my power. I don´t have the time to download the file after every ride, so I need a unit which does not need to be charged every week.
I have the following questions:
1. Is there a realistic change to increase the battery life significantly by a
power consumption optimization or to use a battery with a much higher capacity?
2. In the past some users used an additional external battery to increase the battery life. Is that possible with the Newton too? That would require that the USB-port can be used to connect an external battery.
