BT Advanced Digital Home Phone battery life.

cda123 — Tue, 03 Oct 2023 12:31:09 GMT

Hi.

I've had my new BT Advanced Digital Home Phone with Alexa for a few months and today I made a call that lasted 45 minutes (previously I have made only very short calls on it). After this, the phone battery went flat. Do I have a faulty handset, or is that the expected talk time for this device? The phone was properly charged when I had it installed as per instructions and has sat in its cradle for most of the time.

Any advice would be welcome.

Thanks.

Hi @cda123 Was it speaker phone or through the earpiece?

It was through the earpiece.

Thanks for your reply.

I have spoken for over an hour on mine (earpiece), and the battery was still showing around 3/4s full on mine, so I don’t think it is working as it should.

I would like to say a software update might help with charging management, but sadly it doesn’t appear they have yet worked out how to get this device to update either!

Hi @Anonymous Do you mean the software update doesn’t work? Mine says Software up to date. X65_BT_H31044.

I have the same software number, I just keep hearing a beep once every week or so and get the following message on screen, which I believe is a known fault?

Unable to update

So I don't know if it has updated since arrival and the message is the bug, or it doesn't update as that is broken. You can't force an update either because it says either software is up to date or gives a similar error message.

BT battery management on their phones since they moved away from rebadging Siemens has been pretty awful. Sounds like nothing's changed with the latest ones.

You really need to run the batteries down regularly but that's a difficult juggling act if you only have the one. So you either need a spare phone or a spare set of batteries & a separate charger.

Hi @Anonymous

Have you tried a SH2 factory reset. Mind you there is nothing to gain if your software is up to date.

Yeah @VeteranISPUser the SH2 has been reset previously related to a TV issue.

The phone works fine apart from telling me it needs an update and then failing, which suggests to me the bug is the update message rather than the update process itself, otherwise we wouldn't be on the same version.

I wish I had made a note of which version it did come with to be honest.

Just to keep this live for 2024 – I also, am experiencing extremely poor battery life.

We have 5 phones in our house system and so not a major problem to switch phones. However, when I am in my “man cave” having only been on the phone for just over 1 hr and try to make the next call and find the battery dead - this is not really acceptable.

I have never experienced this short battery life with any of type of cordless phone.

Should mention that they are left on charge overnight but not preplaced on the charger during the course of the day – but then, neither is my iPhone nor me previous Panasonic dect phones.

Seems to be poor quality rechargeable batteries. Has the problem with batteries happened on all your phones or just this one?

My issue remains unresolved. I have been using my old phone line and not the B.T. phone line. I have 2 B.T. handsets. One has useless battery life and the other keeps re-booting or just turning off, so I do not know what the battery life is like on both. At some point my old phone line will be no more and I will have to get this issue resolved. From what I have read, however, I can plug my old phone into the B.T. router. I don't care about the Alexa thing, so that's not an issue.

Many thanks.

@cda123

Yes you can use your existing analogue phone by just connecting it to the socket on back of SH2 once moved to digital voice

Thanks for confirming that I can plug in my old phone into the B.T. router. I think I will buy a new phone identical to my current old phone for when it finally goes to telephone heaven.

You can also ask BT for a free DV adapter which connects to a mains power socket and connect using DECT to you hub and will give you anothe point in your home where you can connect your existing phone if back of hub not convenient

Thanks. I had no idea such a thing existed.

@cda123

Just replace the batteries. You can buy a dozen Amazon Basic for under a tenner.

I have looked at the phone and can see no compartment to open to get to the battery. However, I have now given up using the supplied phones as the battery life is simply not good enough. Sorry for the late reply, but I have been unwell.

Thanks,

CDA.
