I have replaced original battery with aftermarket battery, but from time to time, battery capacity drops suddenly (typical from around 50% to 5% in a very limited time, like 1 minute). I would say that battery is healthy and propperly charged....I also noticed that below around 60% device becomes sluggish and responsiveness and speed are greatly reduced.
Pocketbook Int had received multiple complaints about this, but only advice that I get from manufacturer are very stupid, customer support is very limited. They told me to reformat internal device memory. This is useless procedure. So my advice to all people, like Ezdiy said, to claim defective device as soon as possible and get new device in hope that it will be without defects.

It's worth noting that Pocketbook distribution model in CIS/Europe is somewhat unusual: They do not handle repairs, nor will they replace devices on wholesale channel. It's the exact same thing you get when dealing with chinese manufacturers. In fact, they directly ship from china.
All of this is on the shoulders of the local distributor - that one has to partner up with independent repair shops and if it can't be fixed, they eat the loss. Markups are quite high on pocketbooks due to this, and some less scrupulous distributors have horrible warranty service because they don't have the reserve to deal with the poor QA.
So how does this turn out in practice? You discharge the battery to a point when the sluggishness and crashing start to appear (that can be anywhere between 50-70%). Precisely at that point you bring it to the shop, demonstrate and say this is unacceptable.
In the case of my local distributor, they invariably give it to repair shop to replace the battery for aftermarket one. From there I have the information that it quite often doesn't help. So you get your device back, and it suffers from same exact damn problem. At this point you bring it to the distributor again, they replace the device for a new one and eat the loss.
My local distributor displays warranty claim rate in their E-shop. It's 4% for pocketbook. It's 0.2% for kindle.
I'm not saying "don't buy pocketbooks, they're crap". All I'm saying is make damn sure the distributor you choose to buy from has a good track record wrt warranty - that they're experienced in handling hardware with high return rate. This is not just pocketbooks, but multitude of chinese brands of little to no QA. Don't be afraid of warranty returns, it's often still worth it in terms of price or features. Just make twice sure that the distributor is able to handle returns in the first place.
