We have fulfilled some of the battery purchases on IGG. We previously announced already that the battery listed on IGG is NOT compatible with Pro1, and have asked those who ordered for the Pro1 battery on IGG to contact us. We can't do anything about those who didn't contact us. It is £99 + shipping. Shipping is calculated on a case by case basis.

I've seen some evidence for that. When I set my phone preferred network to LTE Only, the phone switched to LTE Band 12 and I could not make any calls. But, with my normal setting , I stay on LTE Band 4 and everything is fine. I unfortunately don't get out of where I live much, but when I do I'll make more observations.

Dear @Hook and @jakfish, Thanks for sharing the outcome of your investigations. It is intriguing that you get better results with GSM telephony. With my German carrier (O2), I have never been able to place or receive a call on GSM. Only VoLTE will work in the few places where the underlying LTE connection can actually be established. Note that this is not a restriction of my provider: I use and prefer GSM for calls all the time with the Pro1. What is different in our two cases is that US T-Mobile uses the 1.9 GHz band for GSM, while my O2 Germany relies on 900 MHz for that. Also, I o

Just a note. If it is true that the Pro1x can't use VoLTE, either because of hardware or software, there is more to it than that because my phone is not useless (at least until April 2024). It works. One difference between my phone and @jakfish's seems to be that mine, as I said above, stays on LTE Band 4 while his seems to switch bands. As I have also said before, if I weren't on a forum, I'd think I had a fantastic phone with nothing to be concerned about. I am not knowlegable about this stuff, but I hope our observations have some clues.

@Hook and I, both residents in East Coast, mid-Atlantic states, have spent time extensively testing the calling issues with the Pro1x in the United States. Our testing number is: 408-647-4636 The test center allows you to record/play messages and will also test your connection by immediately playing back your voice. It appears the news is not good. The only successful US network for Pro1x calling is GSM. Any other choice (eg: LTE, VoLTE) will result in call failure—no connection, dropped call, or inability to hear caller. This failure is persistent. In T-Mobile’s Preferred Netwo

@Adrienspawn I've spent the day re-looking at all phones within the 3100-3200mAh range listed on GSMArena Phone Finder to see if there are any compatible batteries from other phones and I'm afraid I've not found any. Attached is a list of the phones that I've looked at. Edit: made since 2017. phones_battery_candidates.txt

Hi kif, 4.5.0.18 is ready at least for the Pro1X. Not sure about x.19? @piggz posted the following instructions on telegram: step 1, edit this file as such [defaultuser@Pro1-X ~]$ cat /usr/share/ssu/features.d/adaptation-community.ini [adaptation-community] repos = adaptation-community pattern = Feature community adaptation description = Enable ssu for community ports [repositories] adaptation-community = https://repo.sailfishos.org/obs/nemo:/testing:/hw:/fxtec:/halium-qx1050:/%(release)/sailfish_%(release)_%(arch) adaptation-commun

Wiko WIM - no FCC filing photos that I can find, but a screenshot from a tear-down video produces a ratio of 405px : 653px (battery height : device height) and applying that to the official height of the device of 156mm gives a battery height of 96mm, so not a match. Samsung J6 (SMJ600FN) FCC filing photos: https://fccid.io/A3LSMJ600FN/Internal-Photos/Internal-photos-3818074 Not as clear because of lack of measurement in photos, however taking a ratio of 350px : 571px (battery height : device height) and applying that to the official height of the device of 149mm gives a battery h

I've been recently looking into this myself given the deterioration of the battery (currently approx. 73% health 😬) and having checked the FCC filings (can be found at https://fccid.io/2AUCLQX1000/Internal-Photos/internal-Photos-4458173) you can see that the battery dimensions are roughly 110mm x 36mm. The connector also has labeling on it (FH-F88003B-FPC) although not sure if this is a specification or unique to the cable that's used in the filing. In addition I've contacted Cellonic (https://www.cellonic.eu/) as a long shot, to see if they either already stock a battery of the same
