Couple of clarifications, not all phones use the same type of battery, there are multiple technologies available in the wild, some technologies handle better than other the multiple aspects like overheating, swelling and even constant state of charge.
The best solution would be to control the charge/discharge states of the battery, some very good app allow to do so but they require the ability to be able root the phone, which is still not easily achievable because most manufacturers and mobile network providers block the access to the phone boot-loader, as a mean to force their consumers to buy more expensive model and/or lock them into a monthly subscription.
The ultimate solution would be to run the phone without battery or bypass the charging circuitry but again manufacturers also restrict the access to their device, making hard for consumers to service them by themselves. Glued smartphones are an absolute abomination lol
Have a great week and keep it up the great job 🙏🏽💪🏽
Thanks for the info had a kasa outlet so thus worked great
Great tips Mike.
I always root the phone and set a charge limit to 50%. 85% was never enough in my experience, still had swelling issues a year later.
I like to enable battery protection like you stated on the video batteries are happy around 25% to 85% charge. Some devices do even better by allowing passthrough charging so the battery does not get charged after it reaches 100% the phone will be powered by the USB PD the name is Pass-Through Charging. (Some Samsung devices have this last option too but is hidden under the game home app I'm working to get this enabled without the app)
@Retro Mike Tech Question how to add a wallet and where to add after you enter config. json? (Verus Mining)
You could even have half your phone farm charge one hour and then charge the other half the next hour and back and forth. That way you get consistent power draw.
gl keeping all that work in the nightime too
Hey Mike i was thinking also about an app that would allow you to put a touch block or that would it allow you to turn off the screen completly and keep hashing at the same pace? WDYT?
Where would you recommend to buy galaxy A03s phones? Thanks
Thank you for posting such an informative video. Would you be knowing how to directly download the apk file on a device which doesn't have a google account?
Thanks
any down side to parking it at 50% target? seems thats the least stressful/most balanced level for the annode and cathode materials.
my phones dont stay mining correctly after a power outage seemingly since the display powers off, otherwise the smart plug is clever.
static 50% is good, if you can achieve it. Set the screen timeout to the max value. that should help. or try a screen awake app.
Where are the kasa links? I want to get that AND thanks for the info! I’m so scared of them blowing up 😳

@@RetroMikeTechI just ordered! Let me know if it went through on your end!
@@Financial_FailureI do see it. Thank you very much!
How many hash for that farm ?
Hello sir luckpool manage setting ip invalid problem
Would discharging to 25% and recharging to 85% not kill the batteries? I thought that lithium ion batteries have 300-500 cycle life. This method would create 24 cycles per day. Wouldn’t it?
Wonder if there's a way to run the phones solely off USB without having the battery in place. Just side-step that whole issue.
this is my thoughts I wish someone could create a way
Could you link whatever info you have on how to discharge with a rooted phone? Does that mean you can set percentage parameters for the phone to discharge/charge to?
I don't have any rooted phones, but I did hear that there is an app that allows you to turn charging off until a certain lower threshold and then it will activate charging again.
Do you have the name of the app? Wanna look into it
@@AtomicChill Advanced Charging Control. also this app will run the phone directly from the Charging adapter output. battery charge will only consumed on power outage
Is it possible to power a cell phone without a battery?
Yes, i have done that with 5 phones. Now i don't worry that my phone will catch fire. I want to do it with every new phone i buy.
its happened to my phone 2 times, -_-
This is terribly inefficient. I assume you are mining crypto? All of those phones probably would be outmined by a single high end GPU. Even an RX 6800 at ~400 USD would probably outmine all of those phones combined.
Also this is extremely dangerous as well. I hope you don't have other people living in that home, because you are putting them at risk of a serious fire. If one of those batteries pops, you will have a massive lithium ion battery fire. They are notoriously difficult to extinguish.
DO NOT DO THIS.
Glad I don't have a cell phone or laptop.
"This is terribly inefficient"🙄
I have 10 Samsung A03s mining next to me.
No modifications, no overclocking, the Verus mining workload on these phones is less of a stress than gaming on them (almost zero gpu usage while mining).
All 10 phones combined have a current average of 41.96 MH/s @ 39.95 watts = .9520 MH/W efficiency.
None of my RTX 2060's, RX 6600 XT's, or my Ryzen 7 5700's come close to that efficiency.
"Also this is extremely dangerous as well"🤡
Do you have these concerns while using your laptop, with that comparatively huge battery inside?
Modern technology has come a Long way in protecting consumers from their devices...
@@sixtyinsix Yes, I always take lithium battery safety. So I do have these concerns when using my laptop.
However, I am not running 30 laptops all in close quarters. While the battery failure rate may be low for a single, OEM high quality battery, if you add a ton of devices in a small area your risk of a fire goes up exponentially. If one battery explodes, it is very likely they will all explode and the heat will cause the gases inside to expand and puncture the casing. When that gas mixes with oxygen you will have a very nasty fire.
Also, laptops are designed for continuous workloads and their cooling and battery management systems reflect that.
Anyways I wasn't able to verify the mining rate numbers your cited on the A03s. But this same uploader had a more recent video that was showing a hash rate of slightly over 2 MH/s per phone.
@@bestsoundeffectsyt
i'm sorry but i am sensing a little bit of overall ignorance on your side for these subjects, let me elaborate:
A03S can do anywhere between 3.9-4.6MH/S (i've even seen some that can do 4.9MH/s) - it all really depends on "Bin lottery", miner program used and if the phone was set up correctly with no bloatware and unnecessary services/apps running in the background, but slightly over 2MH/s is extremely low for an A03S.
additionally, some farmers actually take the batteries in their phones out and bypass the batteries entirely - this involves a little more of a hands-on approach, and will basically "destroy" the resale factor of such phone (since you have to destroy the battery and take its electric circuit out to create a "dummy battery") but this makes the phone not so different from a GPU for example.
some phones can also operate freely without a battery installed in them and by pulling power directly from their USB ports (Xiaomi MI A1 for example can do that, my friend has 3 of these devices in his farm that i took their batteries out).
the type of "catastrophe" you are talking about is really not that different even from any day to day device use and daily schedule of many people today.
lets say you have Wireless earbuds, these earbuds usually sit in a charging case, both of these have batteries - so that's three batteries in extremely close proximity - two of which are constantly "charging".
when you charge the carry case - the earphones themselves are usually inside it - so you are still charging 3 devices in close proximity to each other.
usually people would charge their wireless earbuds next to their phone - so now that's 4 devices charging in close proximity.
lets say you charge your devices next to your laptop? - 5 devices.
what if you're also using a wireless PC mouse (for example MX Anywhere) - 6 devices now.
if you have a wireless keyboard with rechargeable battery? - 7 devices.
maybe you also have two console controllers charging on the same table close by? - that's 9 devices now.
maybe you are also using a wireless headset/headphones with that console that's also charging at the same time? - now we are talking about 10 devices that are charging simultaneously in the same proximity - and that is a VERY realistic scenario.
the type of possible similar scenarios can go on and on and on, just because he has 10 phones close to each other DOES NOT make it any more of a lithium battery explosion hazard than some average joe's daily life.
some people also charge their EV's in their homes - with batteries that are x1000000 more dense and more powerful than these small lithium-polymer batteries - they charge at extremely high voltages and currents compared to the sub 5 volts and 2 amps that most batteries nowadays charge at (trickle charge is typically 0.150-250mA too btw).
the risk of an EV car battery fire at home is significantly higher than the risk of a mining phone that is constantly being monitored and checked on combusting.
most miners will take a phone off their farm if they noticed that the battery started becoming puffy - it bulges the display / rear panel and that is very evident - heck if a battery starts to inflate you can technically still use it for at least another month before it becomes a pillow that can blow up every second - that is enough of heads up time for even the laziest phone farmer to notice the puffy battery and decommission a mining phone.
with an EV you have no view of the battery cells whatsoever, you have absolutely no idea if you are sitting above healthy batteries or above what is essentially a ticking bomb.
additionally, it is NOT difficult to put out a lithium battery fire at all - power extinguishers for lithium battery fires have existed for centuries now and are exceptionally effective...
it is difficult to put out an EV fire - simply because the fireman have no direct access to the battery because it is basically underneath the car.
regarding CPU/GPU mining - right now in this bare market is is exceptionally inefficient to GPU/CPU mine using a standard mining rig setup - the MHS/W rate for anything Desktop is just piss poor - Phone Mining however doesn't just have insanely better MHS/W rate, it is actually literally the only method right now to actually mine with a PROFIT (albeit tiny profit, but a profit is still a profit).
even when you compare Ryzen 7950X which is a 700$US CPU (it is the most profitable non-EPYC CPU for mining right now), its doing around 60Mhs on average when all cores and threads are used at around 130W (0.4615MH/W) - mining at decent profit (around 0.74$ Per Day).
take 14 A03S phones (cost around 700$US @50$ per phone), they can do anywhere between 3.9-4.6MH/s - so lets settle in-between at 4.2MH/S? at 5Watts (0.84MH/W)
but that's just efficiency for a single phone, as i said for the cost of a single 7950X you can buy 14, so that's 58.8MH/s (its probably a lot higher, i just used the 4.2MH/s from above) @ 70W and you can clearly see that for more or less the same hash-rate you are being nearly twice as efficient! and your profit is also almost doubled (around 1.34$ Per Day)
and that is completely disregarding the fact that the 7950X also needs to sit on a motherboard that costs money, and needs RAM + Storage, it needs cooling, a PSU etc.
realistically a 7950X mining build is going to cost you more like 900$ rather than 700$, so if you do the more realistic calculation you can actually buy 18 Phones that will mine at 75.6MH/s (probably closer to 90MH/s) @ only 90W for the same amount of money of a single high end highly efficient CPU mining rig - and now you can clearly see the appeal of phone mining and why it has been getting a HUGE popularity boost in the last month over x86 CPU mining / GPU mining.
@@HoLDoN4Sec While I understand and appreciate the depth of your insights into phone mining, particularly with the A03S model, there are several points that warrant clarification and counter-argument:
Safety & Battery Management: Even though the odds of a modern lithium-ion battery exploding are low, the risk is still present, especially when they're being constantly used at high capacities. A study from the University of Illinois highlights that repeated cycles and rapid charging can lead to internal short circuits, which could lead to fires.
Environmental Concerns: Repurposing phones for mining might seem environmentally friendly, but consider the lifecycle of these phones. According to a report by the United Nations Environment Programme, 50 million tonnes of electronic and electrical waste (e-waste) is produced annually. Encouraging phone mining could inadvertently encourage faster device turnover and contribute to e-waste.
Economic Efficiency: While on the surface, phone mining may seem more profitable, it's essential to account for the total cost of ownership. Phones have a much shorter life span when used continuously compared to dedicated mining hardware. This could lead to frequent replacements, nullifying the profit margins over time.
Mining Algorithm Difficulty: The profitability of mining is directly related to the difficulty of mining algorithms, which continuously evolve. Mobile hardware is not as adaptable as dedicated mining rigs. As the difficulty level rises, these phones might quickly become obsolete for mining purposes.
Comparison with EVs: It's a little misleading to compare phone battery risks to EVs directly. Electric car batteries undergo rigorous testing and have multiple safety mechanisms, like thermal management systems, to prevent overheating. According to the National Highway Traffic Safety Administration, the risk of fires with electric vehicles is comparable to or perhaps slightly less than the risk with gasoline-powered vehicles.
Future of Mining: The mining landscape is evolving rapidly. Major cryptocurrencies like Bitcoin are seeing a shift towards more sustainable solutions like the Proof-of-Stake mechanism, making the whole debate on mining hardware somewhat moot.
To conclude, while phone mining has its merits and can be seen as a novel approach, it's critical to consider the broader picture, encompassing safety, environmental concerns, and the evolving nature of cryptocurrencies.
