iPhone 6 does not have wireless charging feature, but you can add it to your iPhone 6 and place the phone onto any Qi wireless charger to start wireless charging. No harm to the phone battery at all. You may try the 3 solutions to add wireless charging to your iPhone 6.
Check the top 10 things to know for a best iPhone 6 battery case.
Let’s get started.
1. What Battery Capacity Is Good for an iPhone 6 Battery Case
The larger battery capacity, the better.
If you are thinking this is the principle for an iPhone 6 battery case when it comes to the battery capacity, you’re right, to some extent.
Everyone likes to get the iPhone 6 battery life extended longer.
However, larger battery capacity also means bigger size for the case, and this results in a heavier and larger iPhone 6 with the case on.
See the relations of the capacity, battery life and the size.
And to give you a clearer concept of how the battery capacity of a case has impact on the size and the thickness, see the picture below:
Our suggestion is, to get at least 1 full recharge for the 1810mAh iPhone 6 battery and at the same time to guarantee a slim battery case, the best battery capacity of the case should be 3000mAh to 6000mAh. Smiphee and TREEZITEK are the good example.
Of course if you never mind a brick, an 8000mAh or 10000mAh iPhone 6 battery case should meet your requirement. But trust me, it takes time for you to get used to it.
2. Charging Speed Varies a Lot Among iPhone 6 Battery Cases
When using a battery case to charge the iPhone 6 wirelessly, it is slower than the traditional wired charging. You can’t expect it to be done within 30 minutes. However, some iPhone 6 battery cases do charge very slowly, for example, about 7 hours.
That would be too discouraging especially when you need to use a power-consuming app like Google Map or GPS or when you want to watch videos. Battery drains faster and charging is slower.
A top iPhone 6 battery case would recharge your iPhone 6 within 3 hours. For example, in our test, Smiphee took 2 hours and 38 minutes to get an iPhone 6 from 8% to 100%, and TREEZITEK 2 hours and 42 minutes from 11% to 100%.

3. Overheating Is a Big Deal
Frequent overheating will do harm to your iPhone 6 battery.
Many high quality battery cases for iPhone 6 have a built-in system to control the heat and the well-made materials would have a good heat dissipation.
For example, aluminum alloy, aluminium magnesium alloy, and all aluminum materials are good for heat dissipation.
Do remember to check the information when selecting an iPhone 6 battery case.
4. Slim or Heavy Duty
As we’ve mentioned above, battery capacity will have an impact on the thickness. If you want an ultra slim or the thinnest iPhone 6 battery case, you need to sacrifice part of the capacity.
A 3000mAh battery case for iPhone 6 is very slim, and would be in the size of 5.6 x 2.7 x 0.5 inches, and a 4000mAh iPhone 6 battery case would be in the size of 5.6 x2.7 x 0.6 inches.
We don’t mean a heavy duty iPhone 6 battery case is a bad choice. But if you’re used to put the phone into your pocket, it’d batter to be slim.
The very thing that bears mentioning is that a slimmest iPhone 6 battery case may still add some thickness to the phone, since it carries a battery built-in.
5. iPhone 6 Battery Case with Front Cover, with Belt Clip or Holster
The bad news is few iPhone 6 battery cases come with a front cover or belt clip or holster. But you can add one to the battery case if you need. Most of them are universal and work with all the battery cases in the market.
For example, you can get a belt clip at Amazon for any battery case you buy for your iPhone 6.
6. Color Options: Black, Rose Gold and More
Many brands do offer several color options, like black, red, rose gold, gray, blue, purple and more, and the most common color for an iPhone 6 battery case is black.
The color option is kind of personal preference. Many prefer a black iPhone 6 battery case, and some would like a rose gold one.
And some would want a cute one. Good news is, adding some cute stickers onto the iPhone 6 battery case would do no harm.

7. Waterproof Feature
Is the battery case waterproof?
You may wonder.
No, most of the battery cases for iPhone 6 are not waterproof. Do not get yours wet, like if you are at a pool.
8. iPhone 6 Battery Case with Lightning Input or with Card Slot
An iPhone 6 battery case would use the 3.5mm headphone jack so you can use the original headphones or use the Bluetooth enabled ones.
In theory, an iPhone 6 battery case would fit iPhone 7 since these 2 phones are in the same size, but it’s not recommended to do so. iPhone 7 uses the lightning port so it’s best to get a battery case with a lightning port for the iPhone 7.
And most iPhone 6 battery cases do not come with a card slot. You can add one on to the back of the case. Most of the card slots or card holders are universal, and this one has all the colors you want.
9. Price: Cheap and the Best Budget Ones
Compared to Apple Smart Battery Case, there are many cheap and high quality battery cases out there at Amazon. For example, Smiphee and TREEZITEK are the best budget iPhone 6 battery cases.
In fact, price can be affected by many factors, like battery capacity, added features, marketing, different marketplaces, etc.
And it may vary from time to time. Check the prices of iPhone 6 battery cases

#1. Smiphee iPhone 6 Battery Case
Extended longer battery life. This iPhone 6 battery case comes with a 4000mAh lithium polymer battery, which can offer at least 2 full recharges. Even though you are a heavy user, this battery pack guarantees your iPhone 6 alive for a whole day (or maybe for 2 days).
Charging fast. In our test, this battery pack only took 2 hours and 38 minutes to get an iPhone 6 from 8% to 100%. It charged super fast before 80% and then degraded a bit. The input is DC 5V-1.5A (MAX) and output DC 5V-1.0A (MAX).
Protective design. The raised sides and hard-shell design add very good protection to iPhone 6. We dropped the phone a few times, and the battery case held it well with no damage. It has matte finish so it doesn’t easily slip off surfaces or out of your hand.
Ultra slim: It’s very slim with the size of 5.6 x 2.7 x 0.6 inches, adding not noticeable thickness to the phone.
Easy to install. It’s super easy (just like 1-2-3 things). The top magnet piece can be easily installed.

What’s not good:
The top magnet piece can be easily installed, but at the same time it can be easily removed. If you put a hard touch on it accidentally, it falls off.
The case does not protect the screen. Although we survived well in the several drops, the screen is still in danger if the phone falls off with the screen facing the ground. It’s better to install a screen protector or get a cover. After all, it’s a battery case on the back of the phone.
