Battery

Hi, I don't think the battery management of the Pegasus is working properly. I charged the Pegasus 100% and turned it off and used it again after 4 days and it has dropped from 100% to 21%. Perhaps this software can be improved moderately. Hopefully it's not the battery quality? I know that DGT also monitors this forum so I hope they respond to this. But maybe one of you also know how this can be improved?

Hi,
It is exactly the same with my device. The battery does not hold its charge for long when Pegasus is not in use. Also, the DGT app shows much higher percentages than the White Pawn app or the chess.com app which show about the same.

It's the same for me with the battery. After switching off, the board is probably not switched off but is in standby mode and has a consumption. If it is a software bug, DGT could release the patch firmware. I think it's an unpleasant flaw in beauty. I would also like some comment from DGT on what to do with this.

I'm thinking of adding another switch to disconnect the battery from the board.

Same here.  Battery life is terrible.

Yes, since there is no "off" function, it must be in a standby mode that uses more power than necessary when not in active use. Needs a fix.

What makes you think there is no off function? 

From the manual:

A switched off device should not have any battery consumption, as is the case, for example, with a mobile phone. With the DGT Pegasus, a battery that is 100% charged discharges in a few days when the device is switched off. After turning on the board after a few days, the battery should have a capacity of about 100% and not be completely discharged. This means that the board is not switched off (disconnected from the battery).

Not true at all. Especially the thought about the phone battery. 

Some semiconductors need applied voltage to retain memory state.

Computers that are switched off consume power. How do you think the BIOS keeps the time? They have a battery just for that for when they are not plugged in to a mains. Or, if you have a network cable connected to a desktop, go ahead and shut it down and look at the network port  on the computer. It still flashes. Where is it getting that power if there is no power being used by the "turned off" computer (please do not say the network cable, if you unplug the mains power the light goes out).

Your phone, even if switched off, will eventually drain itself. Take an old phone, fully charge it, then turn it off (not just standby) and throw it in a drawer. In a few months it will be dead. 

Now, does that mean the Pegasus is using more power than it should be in the "off" mode? Maybe, there may very well be something wrong. 

But the reply was stating that there is an off mode. A lot of electronics use power when turned off. 

The battery of the mobile phone will have about the same capacity after a few days of switching off. Pegasus should also have the same capacity. If it completely discharges after a few days of inactivity, then something is wrong. Nowadays, EPROM memories are used and do not need power.

You obviously are not understanding what I wrote. Sorry, language barrier? 

If you noticed I said about the phone "In a few months it will be dead." Not a few days. Now some of that is just the normal drain of a lithium battery, even when not in use. But it is also the phone itself using battery for certain things to stay alive. 

I also said "Now, does that mean the Pegasus is using more power than it should be in the "off" mode? Maybe, there may very well be something wrong."

I am not disputing that there may be something wrong with the Pegasus. But to say, as you did, that "A switched off device should not have any battery consumption" (for which I gave concrete examples of "switched off devices" using power) is wrong as is the statement I was originally replying to that "Yes, since there is no "off" function" (for which I gave the official DGT documentation). There is an "off" mode and there is a chance that has something is wrong with it. It may also be that it is just a "standby" mode but we can only go by what the official documentation states - that it is an "off" mode. In addition, that is an awful long time to go into "standby" mode (5.45 seconds) or come out of "standby" mode (5.30 seconds). 

Sorry if you still do not understand. Have a good day, stay safe and well. 

{EDIT} - Meant to say, I was flashing EPROMS back in the early 80s, it is not just "nowadays" that they are used. Still does not negate electronics using power when "off". 

DGT sagt sie arbeiten daran. Sie wissen nicht ob es an der DGT-App oder am Board liegt.

1 week not used and it is completely empty 1%. There is no such thing as a spontaneous game!! DGT do something about this because this is no longer normal

If anyone has news about this topic please let me know.

I contacted DGT for this „problem“ and they said, that this is not normal and I should contact my point of sales, to get it replaced. My dealer said to me, that he checked two other new devices over the day and they both have this problem, so he offered me to get the money back, because an exchange for a new board wouldn‘t solve the issue, as DGT said to me.

I decline the offer, because I like the board, but still have hopes, that there will be a solution for it.

Same Here.   I use an external battery, large one and charged my board.  Played a couple games and left it plugged into the external battery.   After a week not only is the board dead but it also drained the entire external battery.   The board was completely shut off.   Such a bummer. 

I had my battery replaced by DGT. Now everything is fine. Only 1% loss in one week 👍🏼 They where very kind and helpful and tested my board for one week. 

I have the same problem, after a week with the board turned off, the battery is complete empty. Now I should return my board to DGT to get the problem fixed by a battery replacement. 
Fingers crossed, 1% battery drain per week will be perfect! Thanks for the information by El-Q!

It's hard to tell as the battery reporting in their app is apparently unreliable. Mine has been behaving better lately 

Got my board back yesterday. Battery was replaced and the board was tested for some days. Now the battery drain is very low, lost in the last 24h only 1%. I am very happy now.

Then I asked about the new DGT App, that's the answer:
I am pleased to say that we are testing the beta-version of the DGT app and is in its last weeks of testing and will be released soon.
