Hello… 
I was just wondering what the battery life was on the Halo. I have found that at 100% when running a 2 to 4 hour program uses at least half or more of the battery. I ran several programs throughout the day and then shut it off at night. When I turned it back on the next day, the battery percentage was down to 19%. There are a few programs that run for almost 5 hours and so I feel like this will require a lot of charging. Is this normal? Going forward, should I expect it to be charged daily? Doesn’t that run down the battery as well?
Many thanks for any help or feedback received. And Infinite Blessings to All, especially those that created this

Hello Nicewolf,
Aha batteries have a long service life. Generally speaking, they can run for more than ten hours. Maybe you can try to fully charge the battery and use it to see if the problem still exists.
If it still exists, please feel free to contact us.
Another precision about charging the battery.
With our mobile telephone batteries, it is recommended to avoid discharging under 50% to keep lifetime as long as possible. Experience done, indeed, it really makes a big difference. It really depends on the type of battery…
So, with the AHA Halo device, is it better to avoid discharging under 50% or is it better to let it discharge until (almost) empty every time, before recharging?

This is a very good point. A good reason to plug in every night. Or plug into a battery bank to keep battery from going to low.

I am presently testing the battery life very accurately. I will post the results within 24 hours.

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.

Buonasera staff Ahasupport, chiedo cortesemente di dare indicazioni per la ricarica per prolungare la vita della batteria.
Ci sono varie filosofie al riguardo, ma chiedo allo staff esperti su come è corretto caricare la batteria.
Tra il 20 e 80 %?
Tra il 20 e 90 %?
È meglio non caricare mai fino al 100%?
Aspetto cortese risposta

You can turn OFF the AhaHalo light. My daughter also suggested I buy a BATTERY PACK for my mum as I only see here every 2 days (in aged care), this works really well as the ahahalo stays charged for several days. Once a week I take the battery pack home to charge overnight. Amazon.com.au : battery packs
Hi Suzy,
I have done the same, turned the Halo light off and use a battery pack where needed. The depletion of battery power is dependent on the programmes that are run on the device.
Either way it’s nice to have a mobile scalar field with RIFE capabilities which was not achievable with the scalar boxes.

Of course the lights (screen and “breathing” lights) were turned off during the tests (see above Battery Needs Lots of Charging - #7 by Shriman).

How do I turn off the Aha Halo light?
Make sure the device is unlocked, then press the up arrow on the dial for about 2 seconds, the Halo light will turn off.

This is some amazing feedback! Thanks Shirman for all of your time and information!!! 
You are most welcomed !
Press the top button for some 3 seconds once the unit is on.
I have found some programmes seem to drain the battery more than others. I regularly run programmes in a variety of sequences all day. Since I have had my Halo I have never managed to go a whole day without recharging. When charging I don’t run programmes and the charge is usually almost 2 hours. Understanding the charging element of any such gadgets is a good idea if you want a good service from the battery. There are several articles and videos offering good advice on keeping rechargeable batteries in good condition. I never charge from my laptop or computer. I always use the cable provided as advised in the manual that came with the Halo. I always charge from a wall socket using a good quality charger. I have a 15 year old MacBook and I have followed the charging recommendations to the letter and I still am using the original battery that still indicates 85% efficiency. Never let the battery run right down and charge as soon as the battery indicator shows battery symbol in red. I did see a post that said to not let battery drain below 50%. I have also seen other advice for other types of rechargeables that advise to not let batteries drain to below 30% which I think is probably good policy. Maybe the aha team could add a post to advise? Thanks
Thank you for your suggestion, we may arrange a post about how to extend battery life
Yes, Thank you. It very important to be able to preserve the battery life and extend it if possible.
