Is Mobius screen gone forever?

I have to say the recent screens have scratch-resistant features also, which the Forma doesn't has: I made a light scratch on it while bringing it upstairs, having the phone on its top (so the camera lens made a scuff mark).
Battery on mine is too still good enought for me, like 6/7 hours at least (I keep it 2 years without using, but once and then connecting to the charger, checking it doesn't gets kept discarged). Good to know the battery is replaceable!
For what I read, color newest has darker whites, but if I would change it, I guess it would be for a device with glass scratch resistant feature: even coloured if by using it within inverted colors would look pleasant.

Edit: @Dr.Drib: it doesn't looks uneven, the lighting on the Forma (imho).

On the earlier Forma ereaders there was a dark band on one side that drew a lot of complaints.

Yours does not have this? If so, you are one lucky person!

As for Mobius screens having a survival advantage? I haven't broken any eInk screens yet but one friend of mine broke the front of his Boox Note 5 screen which, IIRC, has a Mobius substrate when he accidentally dropped a D20 die on it.

Yeah I've seen that, but if you filter to mobius screens, nothing shows up.

About that one: even E Ink tagged the Mobius screen as "durable". So I guess it's better in this regard than other screens. Also, I haven't seen that many posts about Kobo Forma devices with a broken screen.

@Dr.Drib: now that you made me notice of it, I see that dark band anytime lol.
I'm happy of that device, btw.

Now I feel bad that I brought it to your attention.

You're happy with it (as you state), and that's all that matters.

This new pocket reader has a Mobius screen (and Android 16):

It lists Carta1300

Very unclear on some of their territory pages, but they're saying both in some of their marketing for this model:

Carta can use the Mobius substrate and both words have been used to describe the panel for some previous devices.

As it's not clear in all territories for this device maybe it's a mistake. I was surprised to see mobius for a small panel, but maybe it's a good choice for a pocket reader. I can't remember seeing a 1300 panel in an ereader this size so suspect it's new.

AFAIK Mobius was only on Carta, but I don't know if ever Carta 1200 or Carta 1300 (which vary most from earlier Carta in terms of front layers).
I can't see why a small device would need the more expensive Mobius screen. It was for lack of chassis on larger screens. It was hardly needed on 8″.

Pocket readers often have a hard life, and people blame the glass substrate for screen breaks. Funny it rarely happened on Hisense devices that had well designed, very rigid chassis though.

As far as I can tell, Viwoods advertises their 10.6" device as having a Carta 1300 Mobius screen, their 8.2" device as having a Carta 1000 glass screen and their 6.13" device as having a Carta 1300 screen.

For what it may be worth, the Carta/Pearl/etc. is the display designation while glass/Mobius refers to the substrate behind the screen.

Make it and I will buy it. And, I suspect, thousands of other people will as well.

DOG-GONE-IT, KOBO!

END OF RANT.

As long as it's made after February 2027, it will have to have a user replaceable battery. That's when new EU law comes into effect.

Once again Jon, as the long as the device can be opened to replace the battery using non-proprietary tools and the battery can be removed and replaced using non-proprietary tools, it meets the requirements of the new EU law. Which means that current Kobo devices which require a guitar pick, spudger or strong fingernails to open and the battery requires no tool, a length of dental floss and/or a soldering iron to replace are already compliant.

There is nothing in that document requiring a battery compartment door or a battery that can be popped in/out despite your fantasies.

You may also want to check the ecodesign rules for smartphones and tablets which overrides Article 11 of the battery regulation.

Spoiler:

Article 11
Removability and replaceability of portable batteries and LMT batteries
1. Any natural or legal person that places on the market products incorporating portable batteries shall ensure that those batteries are readily removable and replaceable by the end-user at any time during the lifetime of the product. That obligation shall only apply to entire batteries and not to individual cells or other parts included in such batteries.
A portable battery shall be considered readily removable by the end-user where it can be removed from a product with the use of commercially available tools, without requiring the use of specialised tools, unless provided free of charge with the product, proprietary tools, thermal energy, or solvents to disassemble the product.
Any natural or legal person that places on the market products incorporating portable batteries shall ensure that those products are accompanied with instructions and safety information on the use, removal and replacement of the batteries. Those instructions and that safety information shall be made available permanently online, on a publicly available website, in an easily understandable way for end-users.
This paragraph shall be without prejudice to any specific provisions ensuring a higher level of protection of the environment and human health relating to the removability and replaceability of portable batteries by end-users laid down in any Union law on electrical and electronic equipment as defined in Article 3(1), point (a), of Directive 2012/19/EU.
2. By way of derogation from paragraph 1, the following products incorporating portable batteries may be designed in such a way as to make the battery removable and replaceable only by independent professionals:
(a) appliances specifically designed to operate primarily in an environment that is regularly subject to splashing water, water streams or water immersion, and that are intended to be washable or rinseable;
(b) professional medical imaging and radiotherapy devices, as defined in Article 2, point (1), of Regulation (EU) 2017/745, and in vitro diagnostic medical devices, as defined in Article 2, point (2), of Regulation (EU) 2017/746.
The derogation set out in point (a) of this paragraph shall only be applicable where such derogation is required to ensure the safety of the user and the appliance.
3. The obligations laid down in paragraph 1 shall not apply where continuity of power supply is necessary and a permanent connection between the product and the respective portable battery is required to ensure the safety of the user and the appliance or, for products that collect and supply data as their main function, for data integrity reasons.
4. The Commission is empowered to adopt delegated acts in accordance with Article 89 to amend paragraph 2 of this Article by adding further products to be exempted from the removability and replaceability requirements laid down in paragraph 1 of this Article. Such delegated acts shall be adopted only on account of market developments and technical and scientific progress, and provided that there are scientifically grounded concerns over the safety of end- users removing or replacing the portable battery, or in cases where there is a risk that the removal or the replacement of the battery by end-users would be in violation of any product safety requirements provided for by applicable Union law.
5. Any natural or legal person that places on the market products incorporating LMT batteries shall ensure that those batteries, as well as individual battery cells included in the battery pack, are readily removable and replaceable by an independent professional at any time during the lifetime of the product.
6. For the purposes of paragraphs 1 and 5, a portable battery or LMT battery shall be considered readily replaceable where, after its removal from an appliance or light means of transport, it can be substituted by another compatible battery without affecting the functioning, the performance or the safety of that appliance or light means of transport.
7. Any natural or legal person that places on the market products incorporating portable batteries or LMT batteries shall ensure that those batteries are available as spare parts of the equipment that they power for a minimum of five years after placing the last unit of the equipment model on the market, with a reasonable and non-discriminatory price for independent professionals and end-users.
8. Software shall not be used to impede the replacement of a portable battery or LMT battery, or of their key components, with another compatible battery or key components.EN L 191/36 Official Journal of the European Union 28.7.2023
9. The Commission shall publish guidelines to facilitate the harmonised application of this Article.

You are right, although this (or the ifixit) method is way far from being user friendly... Most people will just throw out their ereader and buy a new one at the end of the day. Hopefully not. But there is still a chance if they (or other brands) try the battery door instead. But yeah, very low chance...

[Sirtel]

Well, I personally am only capable of replacing a battery by simply popping it out/in via a battery door. If it gets any more complicated than that, I'll likely break the device, and I have no one to do it for me either. So yeah, I'll have to ditch the device and get a new one when the battery dies and there is no simple, easy way to replace it.
