Hello droners!
I bought a new Phantom 4 Advanced last month, and since the beginning the battery has never be charge up to 100%. Only to 88% maximum, and sometimes 87%. A few days days later I bought a second battery on Amazon, and I still have the same issue... the second battery charge up only to 88% too....
It's not cool for the price of these products...
Have somebody the same problem than me?

I contacted the DJI Support, they advise me to completely discharge the battery and try to charge again... and did it, I have discharged the battery to 1% and charge the battery, but it would not resolve the problem.
They say that UPS come at home to send my batteries to repair, but 3 weeks later I'm still waiting on UPS visit....
Bad, bad, bad...

However the  drone flies correctly, but I'm a bit crazy during the flights because as the battery don't charge up to 100%, itt means that there is a problem and also it's possible to have during a flight a problem with the battery and that the brand new drone crashes....

Thank you for your feedbacks.

Rubenrtvd, sorry for the unpleasant experience with our product and confusion by our support.
The pickup service need to be reserved by yourself or you can bring it to a local post deposit with the shipping label.
We apologize for the inconvenience  caused, please send in the battery as soon as possible.

NEVER discharge a LiPo to 1% !!

Never go below 10% unless absolutely necessary. Quickest way to destroy a LiPo.

FORGET all this about DEEP DISCHARGE .... even DJI now do NOT advise Deep Discharge - the DJI Rep who did suggest this is not observing latest DJI information.

Given the facts as presented that ALL batterys are doing same - it says to me a faulty Charger or unlikely but possible Telemetry data ... if just one battery - then yes probably battery fault. But not if all do it.
How are you registering the charged level ? By LED's or by onscreen display ? The LED's are a very poor innacurate way to do it .. all 4 LED's on means anything from 88 to 100% ...
I would switch on battery and use a DVM (Voltage Meter) to actually measure total voltage of the battery ... at full charge it should be 17.2 ~17.4V  .... (15.2V is storage nominal level)

I would try to find another P4 flyer and test charge your batterys on HIS charger ..... see if you get 98% or higher ... Note it is rare to get 100% as the DJI Smart board prevents true 100% ...
Last : I hope that you do let the charger automatically stop ? Do not manually stop the charge. You wait till all LED's go out after all the various flashing etc. of charging.

If te battery temperatur is cold you will can discharge your battery below 10%.

You can fly about at 30%. Once the battery are cold again, you can discharge below 10% your battery.  The fine is not work with high battery temperature, over 42° the cell initial to have  a damage.

I have a p4pro battery iver 200cycles , 80%healt, 17,16V. Voltage 100% full charge.
I think just 20 flyght again and then go on the bin trash
