Factors that affect how long to charge a smartwatch
What really determines how long to charge a smartwatch? These factors are keys to helping us understand how long does it take for a smartwatch to charge to 100%.
Here are factors that affect how long to charge a smartwatch!
1. Battery temperature
A smartwatch charger and battery, that are exposed to high temperature affects the battery charging. Heat can slow down the charging speed, and ruin the battery life.
The best way to charge is to place your charger and smartwatch in a well-ventilated place or near a fan. Disconnect any charger from your smartwatch, immediately you notice it is hot, or heating up.
2. Charger performance(noise)
A loud noise making charger is dissipate enough energy via sound. A noisy charger is evidence of poor internal charging circuit and that is pretty dangerous for your smartwatch battery.
Technically, the alternating to direct current conversion that occurs in most chargers plugged into wall-mounted outlets, often produce noise from when one element gets heated up.
This energy wastage circuits have poor performance and deliver wrong voltage and current values to your batteries. Disconnect any smartwatch charger that makes noise when charging.
3. Charging current and voltage
The amount of current the battery receives depends on how much current comes out from the charger. It is undeniable that a high current like 2A would charge your smartwatch device faster than 1A current, if they have same battery capacity.
What I means is simply that a chargers with higher output current charges the battery faster than a small amount of current. When shopping for the best charger for a smartwatch, choose one that is rated with higher current value (5V, 2A). The charging voltage should never go over 5volts.
4. Charging cable
How long does it take to charge a smartwatch if the cable is bad? The USB cable is the most popular type of chargers for smartwatches. They have been there since invention of smartwatches but sometimes, the cable just charge slowly if damaged or have faulty connections inside. Wireless smartwatch chargers are the more current options, which is a bit faster, only if you make perfect alignment of the magnets with your watch.
5. charger’s Original adaptor
If you use only the recommended adaptor from the manufacturer, you would be certain your watch would charge for the time stated by the manufacturer. Some third party chargers don’t respect specifications for your smartwatch and even if they do, that may not be compatible with your smartwatch. Forcing a third party charger on your smartwatch may prolong the charging time, and can damage your smartwatch battery beyond repair.
6. Smartwatch’s battery capacity
The battery capacity is the measure of how much energy can your smartwatch battery store. Smartwatch brands deliver their wearable products with different battery ratings. A battery capacity is given in milliamper-hours (mAh).
I recommend you should always ask the battery capacity from your smartwatch manufacturer or you check the smartwatch specification if you see the battery size. Larger batteries take longer to store much charge while small batteries get fully charged so quickly.
For example: a 200mAH battery would get fully charged within a shorter time, than a large battery smartwatch with 450mAH battery capacity.
When next someone tells you his smartwatch battery charges to 100% in 1 hour 30 minutes, ask that is the smartwatch battery capacity. If it comes over 250mAH, that is pretty a significant battery size, which can keep your device running for several hours, days or weeks without recharger.
7. Battery type and lifespan
Lithium ion(Li-ion) batteries are the newest standards for most wearable devices like GPS trackers, smartwatches and smartphones. They are rechargeable and they hold the energy for long. As the battery lifespan gets shorter and shorter, they will eventually lose ability to hold or store charge.
Compared to other kinds of batteries, Li-ion batteries have been proven to minimize the effect of aging on ability to keep charge for long. The best thing is, keep your watch and battery in good condition and their lifespan won’t be reduced and charging time prolonged.
8. Smartwatch model and quality
Charging time also varies depending on the smartwatch model and quality. Low-quality smartwatches have pretty, long charging time, and if you aren’t careful enough, you’ll lose your patience. Manufacturers of branded , premium and high-end watches also invest in fast charging capability, and that is why their wearables take just few hours to be fully charged.
If you are tight on budget, check these very affordable smartwatches under $50 with premium quality, including good battery life. If you want to try the luxurious smartwatches, go to Apple and Samsung or try out these super quality Swiss made smartwatches.
9. Is the watch powered off or on?
A smartwatch that is powered on might still have many apps running in the background. It is no doubt that your smartwatch, like phone will take pretty a longer time to charge if you don’t turn it off while charging. It is simple, if you want fast charging time, just shut down your smartwatch and power it on when the battery has full charge.

4. Large capacity Garmin watches charging time : 3-4 hours
How long to charge a smartwatch from Garmin brand? Garmin smartwatches takes between 3 and 4 hours to charge their batteries. The solar models like Garmin Instinct Solar, Tactix and Fenix 6 pro can chargers faster, if you also plug in the USB cord.
Why I like Garmin watches like Garmin Fenix 6 pro, despite their long charging time, is their really big battery sizes. If their batteries aren’t large, they won’t be able to handle those power-hungry advanced activity tracking function in the outdoor.
