Just Like Electric Cars
They can run for hundreds of thousands of miles without experiencing major battery degradation in most cases.
If you own an electric car, you know it’s best not to charge it to 100% often, since heat and voltage stress will affect battery health in the long run.
Optimized at Nokia Labs
A Nokia facility in Romania use Chargie devices to keep their own development phones safe during heavy 24/7 testing at one of their facilities.
They need to also have a USB data link to the phones while they’re not actively charging, and Chargie was the only soluion they could find on the market.
Our in-house developed firmware and app
are based on scientific data and recommendations
from battery manufacturers.

an actual use case
Chargie works for real people
Robert (Killburn, Australia):
We have kiosk booking devices, which are basically mobile phones, that we deploy to customers. These phones are on 24/7. Some phones would fail after a number of months with battery issues, due to being constantly on charge.
We now use Chargies on all devices to better manage the charging cycle. This has substantially extended the life of our booking devices.
Fun fact: some people keep stealing Robert’s Chargies (they’re displayed in public places), so he keeps ordering new ones. We feel flattered people take the risk of stealing Chargie devices, but it’s so sad it happens. To anyone involved, please don’t do it any longer, theft is a bad thing.
unique CAPABILITy
Charging Scheduler
Chargie’s “Top Up Scheduler” has the unique ability to keep your phone at a safe state of charge during the night (50 to 70% is best) and only top it up to a value of your choice in the morning, just before you wake up.
This allows you to both protect your battery health by avoiding prolonged high states of charge and still use the phone at its full battery capacity. It’s much better than current stock solutions implemented by some of the manufacturers.
heat kills batteries
Overtemperature protection
Sometimes, it’s better to just stop charging in high temperature situations, like when using your phone as a navigation device on your car dash in hot summer days.
In such cases, heat degrades the battery’s internal structure more than anything and if exposed to heat for a long time, the battery eventually swells and can ruin your phone or explode.
All phones have some sort of overtemperature protection, but the factory threshold is often set too high to properly protect a battery from premature aging (50°C / 122°F).
Chargie allows you to charge your phone at much lower temperatures, so that your battery health doesn’t degrade as much during long sunny drives or hot summer nights. Automatically.

use chargies everywhere
Innovative charger detection
Distribute multiple Chargie devices across the places you frequent to streamline your charging experience. With a Chargie at each of your regular stops—your residence, workplace, and vehicle, you will seamlessly maintain your device’s battery at mid levels throughout the day, which will have huge impact on your battery performance and longevity. The app will detect and connect to them automatically.
The convenience of this setup lies in the effortless transition from one Chargie to the next, enabling continuous charge without the need to juggle multiple chargers or adaptors.
multiplatform battery care
Works with Apple, Android and Windows
Chargie has apps for iOS 13+, Android 6+ and Windows 10+. We test the app on various Apple, Samsung, Xiaomi, Huawei, Google, OnePlus devices and various Windows laptops.
Actually, Chargie will even work with your Watch or any other device that has a battery by using its built-in Hardware Limiter. You just need to first configure its power threshold to 1.2W in the Chargie app on your phone or tablet and it will stop charging completely when full.
why chargie works
The science behind active charge limiting
A typical smartphone charges up to 100% and then keeps the battery in that very high state (around 4.35 volts) until the user disconnects from the mains.
The battery is indeed protected from thermal runaway by its internal circuitry (it would catch fire otherwise), but the measures taken happen at extreme values, and are not optimized for a long and sustainable battery life.
Why all-night charging is bad for your battery's health
Holding a 100% charge for many hours at a time induces a voltage- and heat-related stress and damages the internal lithium lattice of the battery, at a molecular level (see reference).
Limiting the charge level below 100% or releasing it once it has topped up has hugely beneficial effects for the lifespan of the battery.
An optimized charging process can take a normal phone battery from 250 cycles to more than 1000, before it shows signs of degradation (tables courtesy of batteryuniversity.com [1]).
This has been well documented by the scientific community. Electric car manufacturers like Tesla already advise against charging their class lithium ion cells to 100% by default and keep a 5kWh reserve in the battery, so that you can’t discharge it to 0.
Warm and fully charged battery = dead battery
Lithium-ion suffers from stress when exposed to heat, so does keeping a cell at a high charge voltage. A battery dwelling above 30°C (86°F) is considered elevated temperature and for most Li-ion a voltage above 4.10V/cell is deemed as high voltage. Exposing the battery to high temperature and dwelling in a full state-of-charge for an extended time can be more stressful than cycling. Table 3 demonstrates capacity loss as a function of temperature and SoC.
(batteryuniversity.com)
Cycles don't tell the whole story
The damage each cycle does to a battery depends on the depth of discharge, time of charge and temperature. Lithium Ion units are very sensitive to depth of discharge and temperature. The lower you go, the worse it gets for the battery, because the internal resistance of the cell rises and energy is lost through heat (just like a classic lightbulb). Some papers refer to cycles as a continuous charging process from zero to 100%, while others add mini-cycles (like from 30% to 50%) to this equation, but they’re not equal in terms of battery degradation, since five 40-60% cycles don’t do the same harm as one 0-100% cycle and then keeping it fully charged.[1]
Introducing Hysteretic Charging
Besides limiting the charging process, Chargie’s hysteretic algorithm (see what hysterestic charging is) makes sure that even if you charge to 100%, the process is stopped until the battery discharges down to 95%, and then restarted. This is way less stressful for the battery and dramatically prolongs its lifespan. You can adjust the allowed discharge percentage manually from the app’s Settings menu.
Practically, it is best if you can keep the charge between 20% and 90%. If you do so, Chargie will apply the hysteresis you set, and the practice will yield much better results in the long run, from both a battery lifespan and daily usability perspective.
Ideally, the lower the daily charge, the better it is for the battery. However, you should take care not to overdischarge the battery either. For example, if you regularly go down to 1%, it’s better if you set the top up level to 100% for the morning. Chargie will keep the base level at 60% and will only stay at 100% for a brief period of time.
By applying hysteretic charging, the risk of battery swelling and fires is greatly reduced (unless the battery itself has a physical defect). Google this.

for harsher environments
Chargie contains Gold (Au)
Chargie has a tiny amount of gold deposited onto every inch of board and its connectors.
This is great because the production process is lead-free, gold doesn’t oxidize and it is one of the best treatments for copper.
Your Chargies will last much longer in harsher and wetter environments. Gold does not rust.
new hardware, better charging
Your feedback was heard
Our newly redesigned app, hardware and firmware
are fully packed with new functionality such as:
Autonomous (appless) charge limiting
The Chargie app normally runs on your smartphone, but now you can limit the charging of any kind of lithium ion battery, or of a phone that’s been shut off. It will cut power at about 90%, based on power measurements done automatically and continually by Chargie’s hardware.
Data passthrough/Android Auto mode
The new Chargie A GE and Chargie C Basic now have a working mode that does not cut power completely to the phone while it’s not charging, so that it can be used with Android Auto and USB tethering.
Overcurrent cutoff protection
If your load consumes more power than it should, Chargie automatically cuts it off and restores it as soon as it’s rebooted or within the next scheduled charging cycle. That simple.
Smaller form factor
Chargie A GE is 25% shorter and 10% thinner than Chargie Founder Edition, which makes it more portable and insertable. Chargie C is even smaller – check out the hardware features page.
Stealth mode
The LED lights in the new Chargie A GE are as important as before, and they indicate the same thing. However, they are now configurable, so when you turn off your phone’s screen the two LEDs turn off automatically, to reduce nighttime light pollution.
invest in your phone
Chargie will be free after a month of usage!
To figure out how long it takes to recover the investment in Chargie, we can divide the investment by the cost of replacing a $1,500 phone at a 10% average yearly degradation rate.
We’ll assume you’ll switch your phone at 50%-60% battery capacity.
In reality, you’ll do it sooner than that, due to the discomfort frequent charging inflicts on you, but:
- $25 (cost of a Chargie device) / $428.57 per year ≈ 0.06 years (less than a month).
- If your phone cost you $500, it’ll probably take three months to recover your investment. But the non-degrading battery experience will still totally be worth it.
Chargie Makes Your Phone Greener!!!
The electronics industry is one of the greatest sources of pollution that are affecting the health of everyone. We just don't like to think about it, but phone-making is done with great human sacrifice. We should cherish these devices.
Since 2015, phone manufacturers started gluing batteries inside phones.
They are now very difficult to repair once the battery capacity depletes beyond comfortable usage levels, which usually happens at the end of the two-year warranty period.
On the other hand, from our calculations, Chargie has saved around 5,500 metric tons of CO2 since we started the project back in 2019.
After you upgrade, you can donate your old phone to someone in need or someone who is not as picky with tech as you are.
That person may be using it for many more years, and will not need to buy a new one, thus preventing even more pollution from being spewed out in the atmosphere and into someone’s lungs!

Practical Use Cases
Phone lifespan extension
Chargie has been designed to protect batteries. Just juice your phone through it and in a few months you will see the difference:
– Your battery life will be like when it was new
– We are working on implementing a Chargie Certification Program, so you can have a higher resale value, should you decide to sell it.
– After you upgrade to a new phone, you can safely give a perfectly working gift to someone in need.
– You can use the same Chargie on your next phone, too. We still have lots of customers using the original 2019 Founder Edition Chargie every night!
Charging safety
There have been cases where people who were sleeping with phones under the pillow died, because the battery caught fire. Here’s a Google Search link to news about the topic. Happens all the time.
According to the National Sleep Foundation, studies found that around 45 percent of parents and 30 percent of children sleep with their cellphone or tablet in their bedroom with them, oftentimes leaving the devices turned on and plugged in throughout the night (link here).
With Chargie’s charging scheduler, those devices can stay charged at 50% overnight and the risks of fire will most likely be close to zero.
Always-Charging Phones
Demo phones and tablets in shops usually stay connected to the mains, and that’s what destroys their batteries. After a few months they start swelling or even catch fire, in severe cases.
Chargie automatically ensures the battery is only charged partially, hence the damage will be almost zero and the risk of fire is null. This also increases the resale value of those demo phones.
Always-on remote surveillance
Phones and tablets are used as surveillance equipment in many cases (like that project that protects forests from illegal tree cutters). They often run on solar power, but their batteries stay charged to 100% all the time. Hence the risk of swelling, fire and general malfunctioning of the system. With Chargie, those devices stay charged at 50% and the risk of fire will be zero.
Taxi / professional navigation
Professional drivers (taxi, Uber, trucks, pizza deliveries) use tablets and phones as navigation systems all the time. They stay charged up for thousands of hours every month, placed in direct sunlight.
Batteries get very hot, very often.
Fully charged lithium ion batteries and high temperatures are a very dangerous combination.
Chargie can do away with all that by limiting the charge to some 50%. This way, battery damage is greatly reduced and the risk of catching fire is eliminated.
Fleet management is on its way to the app soon.
Basic Battery Protection
Chargie’s hardware limiter provides a simple yet effective solution for protecting regular batteries that don’t have smart capabilities. By measuring instant power and detecting when it falls below a certain threshold, Chargie’s limiter can cut off power to the battery without the need for an app or any additional programming. This hardware-based approach ensures that batteries remain protected against overcharging, which can damage the battery over time and potentially even cause a fire. With Chargie’s hardware limiter, users can enjoy the peace of mind that comes with knowing that their batteries are always being charged in a safe and responsible manner.

Upon morning awakening I remove my S10+ from the wireless charger (set for slow-charging only) confident it'll be at 70% state of charge. Actually that's often sufficient to get me through the work-day, though I can calmly top-up in a few mins using fast cable charging up to 80%-90% downstairs while I have breakfast, happy that it won't be sitting at that state of charge all day. My phone is like an extension of me, but looking after it can feel like a drag sometimes and I feel anxiety about needlessly wearing out the battery. Chargie's simplicity has improved my quality of life.
David Baylisscustomer, US
Working perfectly. My old Sony phone had this feature built in, and this had best battery longevity of any phone I've had. New phone doesn't, so got a chargie. The hardware arrived quickly.
Tim Chickcustomer, UK
I can't believe someone finally made this. I was monitoring my phone battery for years, and now it's just plug and play. I ordered 3, for my car, my office and my home. Extremely useful to me.
Cristophe Jeannettecustomer
I just started using this last night and I'm so excited! I think it's revolutionary - not only will this extend and preserve my phone's battery, I'm conserving energy and helping to save the planet! So far, so good...
Warren BoykinCustomer, US
"The product is a great idea! I'm tired of replacing batteries because of wearing them out by charging them to 100% all the time. No one is currently doing what you're doing - other solutions all require rooting the phone, or things like WiFi smart plugs and IFTT."
Mark McKenzieEngineer, UK
"Did some research on the internet. There are a lot of "experts" out. Fact is overcharging to a too high voltage and heat are the Li Batteries enemies. Modern devices are somewhat protected against overcharging but your Chargie is the only device I found which do it right."
Georg MackuMaker Faire, Austria
Works perfectly! Smart idea and keeps battery con fully charging at night. Only gripe is the Chargie notification showing all the time, you can turn it off but it'd be better if it appeared and disappeared as needed. It took a while to find this device (I think I followed a link in a forum) so I think it could be marketed better as it's a really useful device.
Mitul Patelcustomer, USA
It works just fine. Chargie can not only make your battery live much longer, it also prevents battery fires and explosions. Set it to 60% to make the battery last almost forever, but even settings like 80% will already extend the life span so much that you will probably discard your phone before its battery loses too much capacity. Root is not needed.
Hans Georg MichnaCustomer, Germany
I've been waiting for a device like this for YEARS. It's highly worth the purchase to better handle battery charging management to allow your battery to last longer without degradation vs Charging to 100%. This is the companion app to make it work completely.
Heather ChoiCustomer, US
Works exactly as described. Thanks for a charging solution that saves the longevity of my battery. Easy to setup, easy to use interface. I highly recommend this to anyone who wants to preserve their cell phone battery. Use 60% limit whenever possible, and charge fully whenever needed. Simple.
Mickey, UScustomer
This is a great software/hardware tool to prolong the life of mobile device batteries. Repeatedly charging a battery overnight will make it deteriorate quite quickly. This app, with the Chargie stick, will prevent this from happening. Other apps which limit a mobile device's charge will require the phone to be routed. Do you want to risk that on your flagship Samsung or Apple device? Warranties will be void and you stand a chance of bricking the device. This app does exactly what you want.
Tim Burgesscustomer
1st - I'd like to mention that after my order got lost they shipped another using DHL! FOR FREE! Pros: * Works Great! * Much nicer and cheaper then using a smart socket setup fo the same + portable! use it outside / in car... Cons: (minor) * had to use a USB extension cable in the car - blocks the 2nd charge port for the dashcam. * Powerbanks - when it cuts the power to phone - p.b cuts the power to chargie. * Usb c to A adapter = no usb pd / qc 4.0 speeds. Bottom line - will order more!
Max Leibermancustomer
Excellent solution to the problem of battery decay. It is almost criminal that smartphones have this inbuilt death spiral. It took me a while, however, to get the chargie to work correctly. It seems ok provided you have the app open when you plug in the charger, and wait until it shows all is connected.
Andrew Claxtoncustomer
Works as advertised. Have installed three of them in different places where I charge my phone (Galaxy Note 9 with Android 10). I just plug the phone as you would normally do, the app on the phone connects to the chargie and takes control of the charging process. I reckon manufacturers could easily incorporate that function into their phones , but why would they do that, if it costs them sales volume because their phones and tablets would last much longer. Thanks, Chargie!
