This is the result of my battery test with a brand new Aha Halo unit.
Charger is a standard 5V phone charger at 1A. A program was running all the time between battery level checking (not the same program was running during different periods. I used a different program each time).
- Starting charge : 100%
- After 15 mn : battery charge was at 90%
- After 30 mn : battery charge was at 83%
- After 1 h. : battery charge was at 80%
- After 1:30 : battery charge was at 80%
- After 2:00 : battery charge was at 78%
- After 3:00 : battery charge was at 76%
- After 5:00 : battery charge was at 69%
- After 9:00 : battery charge was at 51%
- After 12:00 : battery charge was at 31%
- After 15:00 : battery charge was at 17%
Then I stopped the test.
Conclusion : The battery life on my brand new Aha Halo unit is coherent with what is announced by the company. It could have run for 17 hours with still a few percents left.
When stopped for 24 hours the battery maintains its charge perfectly.
The idea of not using the battery below 50% is not correct. The most difficult and damaging charge period for a battery is when it is charging between 90% and 100%. Charging from 20% up is no problem at all. The best would be to stop at 90% to increase battery life, but most of us don’t do it (for phones, tablets, etc.).
I hope this will shed some light on this subject. First I thought that my Aha Halo battery was weak and defective. No, it is not. The battery is not very large. Therefore do not expect a battery life of more that 17-18 hours at most (programs running time). Thank you.
