1. Use the correct charger that was supplied by the manufacture OR a reputable Companies like (Anker and Belkin).
2. Chargers from Convenience stores or those under 10.00 are most likely insufficient – Best to check reviews first.
3. Use the correct cable – very important. Quality cabling affects data transfer speeds and charging. Cables greater then 3 feet (1 meter) such as the 15 foot or 4.5-meters charging cables should be avoided.
4. Consider keeping your phone up to date as new patches and features can aid in preserving battery control and enable better power management
5. Keep away from heat sources
From direct sunlight, near heaters, away from exhaust fans from laptops, desk lamps
Best Charging ambient temperatures, with 62° to 72° F (16° to 22° C)
In a glove box, vs in direct sunlight if charging in a vehicle
Charging your device when it’s inside certain styles of cases may generate excess heat, which can affect battery capacity in the long run.
Fast Charging Scenarios:
Scenario 1 Time More then 3 Hours. Example: Overnight Charging, no rush, constant charging is available, night stand charging
First be sure to adhere to the above Good Charging Practices.
Can charge with computer cable for Android and Apple Phones. Since Time is greater then 3 hours.
Wireless charging is a good option here as well, as it charges the phone at about the same rate as the original 5W adapter.
For Android: Use a charger that says 2A (2 Amps) or greater. Unlike Apple, phones that are designed for fast charging includes the fast charger with the phone.
For Apple iPhones:
For this scenario the original white cube charger will be sufficient. No need to use a more powerful charger. Like ground shipping you have time on your side. The White cube charger from apple will charge a depleted phone in about 3 hours at 5 Watts
Scenario 2 less then two hours but more then one hour of charging time. Example: Have a Date! Event Planned – Anticipate Lots of pictures and movies.
First be sure to adhere to the above Good Charging Practices written above.
In this scenario its best practice to stay from wireless charging as well as charging your phone with your laptop.
If your battery is below 20% consider placing your phone in airplane mode prior to charging.
If your expecting a call the considering enabling low power mode. Either way I recommended you don’t use the phone while it is charging as the power supplied to the phone for charging is partially diverted to screen and computing power when your using it while charging.
Android: use included quick charger or equiviant charger 2A or greater.
For Apple: Advanced Quick Charger is NOT included. You can either use an alternative charger from Anker, Belkin, or another good company (Be sure to check reviews). The included square white cube charger is insufficient for quick charging.
Quick charging options for Apple include:
Use your iPad USB charger [12W ~2Hrs & 20 Min ] (if you have one) as long as you have a USB to Lightning Cable. Apple will gladly sell the cable for 19 dollars as of 10.11.18.
Use reputable chargers from Anker: https://www.anker.com/products/108/203/wall-chargers
Range from 10 to 40 bucks, depending on what cables you have. Each USB or USB-C is at least 2A.
For Apple (Fast Charger 30Watt) ~ 2 hours AT ~50 Dollars
Notice that double wattage does not mean double charging speed. 87 Watt Adapter for Apple MacBook which can charge iPhone if you have the correct cable will not charge the phone in 20 minutes, continues to take about 1.8 Hrs.
Scenario 3 Less the 45 Minutes. Example: Have a Date! Event Planned – Anticipate Lots of pictures and movies. NEED MORE POWER
First be sure to adhere to the above Good Charging Practices available in the notes.
Follow Scenario 2, be sure that you are using a charger that is 2A or greater.
Wireless charging or charging by a laptop here is not optimal.
What else can you do?
1. Most effective – Shut phone off. Prevents background apps and keeps phone off. Keep the phone cooler since it is off.
2. Effective: If you can’t shut phone off – airplane mode as soon as you can. If you are expecting a call – low power mode as soon as you plug in the phone.

All charging, at the beginning and in between discharge tests, is done with a SkyRC D100 charger.
You can find it here: https://goo.gl/CQ4JBQ
or here: https://goo.gl/73HNYT
or here: https://goo.gl/91mAkw
All charging data is captured via the Charge Master software. Only the initial charge data (from storage to full) is shown in the video, for reference – the rest are used in order to reconfirm mAh drawn vs mAh charged etc.
Internal Resistance measurements are also taken with the D100, at storage voltage and at full charge, with no load. IR measurements are to be taken with a grain of salt, since they can vary due to temperature change, exact voltage, battery leads length (especially balance leads) etc.
All discharging tests, both for the capacity test and for the discharge stress tests, are performed with a CBA IV (Computerized Battery Analyzer) from West Mountain Radio: https://goo.gl/d4FhTQ
You can find more details here: https://goo.gl/e9G7nE
It is a unique piece of equipment that can accurately test and, through its user friendly software, log all the valuable data required to properly evaluate and compare the quality and capabilities of a battery.
The capacity test discharges the battery at 1C rate, down to a cutoff voltage of 3.2V. It graphs the whole process and marks the point at which the 80% capacity has been discharged. It also outputs an average IR rating for the entire test, which will be useful when comparing batteries of similar spec. Temperature is monitored just as a safety precaution during this test.
The high discharge test is where things get interesting:
Most batteries can be considered more than good for cruising around, but the best performers can only shine when stressed. The goal is to stress test the batteries and identify which ones “pack more punch” and for how long.
The discharge rate is based on an average in-flight amp draw at 90+% throttle of a quadcopter, using a motor/prop type and size that corresponds to the type and size of the tested battery. The batteries are categorized and tested accordingly, so that a meaningful comparison can be easily done, as a real-world use-case.
The CBA IV can be triggered and controlled via scripts, for more automated tasks. In my case, each discharge test is triggered by a custom made program called “MuteFPV Discharge Helper” (check below for more info).
The CBA IV begins to draw current until it reaches the pre-set amp draw test current. The refresh rate of the CBA IV is 1 second so exact times of each run, from trigger to end, are logged by the Discharge Helper.
The tested battery is discharged until it reaches a cutoff voltage of 3.3V. It is then allowed to recover for 5 seconds, before the next run is initiated. The repeatability of the test and its intervals is handled by the Discharge Helper.
When the battery fails in two consecutive runs to deliver the test current, the test is considered finished and automatically stops.
Temperature is not to be neglected during this test. It is constantly monitored and logged during the whole testing procedure, via the temperature probe of the CBA IV.
Huge thanks to Joey and Darren from West Mountain Radio for their continuous support throughout the preparation of this video series. Their help has been absolutely invaluable.
Extra-special thanks to John Norrbin (aka Johnex) for creating and customizing the “MuteFPV Discharge Helper” program, specifically for the needs of these tests. You can get in touch with him on Discord, here: https://goo.gl/LEqcTW
** The batteries tested have not been cherry picked, at least to my knowledge. They are brand new and unused batteries, tested right out of the box. Nevertheless, your results may vary. **
** Never leave your batteries unattended while charging / discharging. All these tests have been conducted under my supervision and full attention. All the data is monitored in real-time, to ensure the safety and quality of the test procedure. **

Also called a Buck/Boost transformer, this mod lowers the voltage to the charger and makes it a low current battery charger. An example of how an auto transformer can be useful. This dump find had bad diodes and missing leads.
Tesla recently introduced a wireless, portable smartphone charger, but the device sold out within a day on the company’s website. Business Insider reports the chargers originally sold for $65, but Tesla just announced that the new batch is getting a price drop to $49 — and everyone who purchased one for $65 will be reimbursed for the price difference. The chargers have a 6,000 mAh battery, 5W of wireless charging output and 7.5W wired, and serve as a portable power bank.
