Lumia 950xl random reboots build 14379

[Lumia666]

This is a battery issue. My battery has swelled alot, so I ordered a new one. Still waiting for it.
Read on some Swedish page that when the battery was replaced, the issues stopped.

Your battery is dead (and probably already swollen).

Just wanted to give a big thanks to Mak11, I ordered a new battery from Rounded.com as per that thread and I've been green flash and reset free for the past 2 weeks now. Wanted to give it a good bedding in period before I confirmed but it was instantly noticeable really. Thanks and this really should be publicised a bit more, especially now they are saying there are no Warranty repair devices left.

I am not sure if my frequent reboot issue is 100% related to battery because I checked my battery but didn't see visible shape change.

Where to buy authentic battery now?

I think Amazon or eBay are good places to start looking for battery's replacements.

This is the exact one I ordered: Microsoft Lumia 950 XL, Lumia 950 XL Dual Battery BV-T4D 3340mAh

Thank you!

Can I ask how long have you been using the new battery and have you seen new battery damaged by fast charging and random reboot since?

I'm experiencing the exact same thing. I thought that it was because I was on the Insider Fast Ring as it started happening with the first Redstone 2 builds - 14905, then 14915, then 14926 and now again today on 14936. I did a hard reset on 14926 and it persisted. My firmware is 01078.00053.16236.35006, which I think came out around the same time, and I've heard that's the culprit, that it causes the battery to fail. I've seen posts on Reddit where people with this issue replaced the battery and it went away. I'm going to go to the Microsoft Store tomorrow and hopefully that will fix it.

It surely isn't any of the Insider builds. I was on all the Production builds since January when I got my phone. I started to experience these crashes/green flash/unlock reset/constant reboot when battery drops to like 40% or less after the second Anniversary Update. The battery warranty is sadly only 6 months so I just went ahead and bought the battery mentioned in this thread. I will receive it hopefully in a week. I'm afraid it may cause an issue with my new battery eventually if it isn't fixed in any of the latest builds.

Hi all, unfortunately my issue has returned only 8 months out of the battery and I'm having the same issues again, it started around 10% and has slowly worked up to happening at 40% today.

I really don't know what to do now, as I want to be a part of the Redstone 3 testing but I also need a phone that works. Paying another £30+ for another battery is really annoying and I've only had the phone a year and 5 months, so that's 2 batteries dead within what would be a 24 month contract (I luckily dropped out of contracts and am on a rolling £10 contract).

It has to be a defective handset, why are others not seeing this?
