What capacity shall I buy the Power Bank for my phone?

A Power bank is also known as battery charger. It is used by peopel when they are going out without a Travel charger or Car charger for emergency use. Initially it was powered by dry cell batteries for old Nokia phones without a touch screen. As li-ion battery cell technology developed, it was made up of li-ion battery and Li-polymer battery cells. During this time, the power bank capacity was high and could be used for touch screen smart phones or tablets.

You can find 1800mah, 2500mah, 4000mah, 8000mah , 12000mah Power Bank in retails. So, there goes the question, how can I know the capacity of power bank I am going to purchase? How can I know it will meet my requirement or not? Here we go some useful tips from us:

We buy a power bank with capacity of 4000mah. Normally it would be about 15-20% less for the output capacity, some even good ones only 10% or less loss. Why this happen? The capacity of the power bank is counted only by the battery cell, 4000mah. But the output should go from battery cell to PCB board with circuits and ICs, then to charging cables, then to your phones. During this process, there will be about 20% loss. You are right, it is crazy to know this. So, the real capacity is about 4000mah * (100% – 20%) = 3200mah.

Let’s continue to charge your phone now. If your iphone is 1850mah battery, there should be 3200mah / 1850mah = 1.73 times. We say, 1 time full and 70% the 2nd time.

But, I want to let you know, this is just in theory. Why? Actually in our charging process, the phone is still on. It needs power to support the phone working. Under normal condition, it can only charge this phone 1.4 ~ 1.5 times.

Question: I bought a 4000mah power bank, I can charge my phone with 1800mah battery 2 time FULLY.I am not joking. Why?

Answer: this may caused by the following: 1) the power bank capacity is 4000mah or more, and the loss is less than 20%. It will charge your phone 2 times full. But Lider Industrial Ltd will let you know that, things like you described are very slim. 2) Your phone is 1800mah, but after a year of usage, the real phone battery capacity dropped to 1600mah or even lower, 1400mah. So, 4000mah*80%/1600mah (phone label may say 1800mah) = 2 times full. The 2nd one is the regular rule.

iPhone needs to be cool down

Have you ever met this screen shot in your iPhone using life? Your iPhone suddenly gets hot although you’re not using it in a hot summer or it’s not charging, then you should pay attention. An overheating phone will lead to a faster battery draining or even cause the battery to explode, which is dangerous. Why it happens? What to and not to do when a phone gets too hot? Here we go:

What is the cause?

1. High Temperature. The working temperature for a smartphone is 0~35 degrees Celsius, equals to 32~95 degrees Fahrenheit. Be aware when your phone is exposed to a hot summer or direct sunlight for a long time.
2. Intense Workload. Too many apps running in the foreground or background results in the processor always working and lasting in an overload status which makes the device unable to dissipate heat timely.
3. Poor Signal. If your device is in a poor mobile network, the device will increased transmitter power to have a massive data interaction with nearby base stations, which will also lead the processor to run in overload and have no time to cooling down.
4. Faulty Battery. An original battery which is about to finish its service or a faulty battery produced by a third-party manufacturers.
5. Heavy Covering. Cover your phone in a protective case or some heavy stuffs will bring on poor heat dissipation.
6. Calling while Charging. Battery inputs and outputs at the same time will produce heat and the input and output of electric current will also put you in danger when you’re calling while the phone it’s charging.
7. Software Incompatibility. An iPhone after jailbreak or an Android phone after root may be installed some malicious or incompatible plugins without notice, which give rise to the cellphone heating.

What to do?

1. Keep or use your phone in a good ventilation place.
2. Turn off background running apps and uninstall the seldom use or never use apps.
3. Disable auto download and auto update selections.
3. Remove the protective cases when a phone is getting hot.
4. Use a good quality earphone instead of placing the phone close to your cheek when having a long conversation.
5. Stop the app you’re using or the video you’re watching when a phone is getting hot.
6. Install a professional app to detect what causes the phone to heat.
7. Watching out the weird overheating at any time.
8. Power your device off to let it rest for a moment.
9. Turn to local service center or repair shops for help.

How to avoid?

1. Avoid playing a game, watching a video or calling while the phone is charging.
2. Avoid protecting your phone with poor heat dissipation case.
3. Avoid charging your phone with faulty chargers or cables.
4. Avoid holding your phone or putting it into a pocket when it’s getting hot.
5. Avoid rapid cooling like placing it in a refrigerator or in front of the air conditioner as the large difference between the inside and outside of cellphone will lead to condensation which will damage the phone.
