[Microsoft Lumia 950/950 XL] GentlePhone:
I've just popped in a mugen battery in my xl, I must say, its big and heavy,

if anyone is interested I can post some photo's and l'll update to let ou know how I get on, my primary reason for this was the difficulty of knowing if a battery is genuine, I've bought 4 cheap ones from china all stamped official but don't seem to match the original battery, all of them seem to last less than the original, although my original had double in physical size and would no longer fit in the case, so I thought i'd take a gamble on mugen, I would of bought a standard size one from them as I've found them to be good in the past.

so far all battery monitoring apps state the capacity as the same as the cheap ones and the original which makes me think they just list the spec for the phone and don't check, does anyone know if there is a battery app for windows phone that can correctly find the capacity?

I got the battery from amazon after contacting mugen asking if they can put it in stock on amazon as my only other option was to ship from USA which was coming to almost £100

I paid £62 delivered, if its ok to post links i'll post one to the thread.

This battery is making me consider getting a 950, it looks a lot more compact the extended one for that!

** update **

only been using it 5 days, charged twice, both times had more than 30% left I just didn't want it to run out in the day.

Battery easily lasts 2 days usage but will need charging on the second night.

Phone hasn't crashed once since using this mugen battery, and this is during Britain's heatwave, haver taken around 70 photo's, usually it would of crashed at least once doing that sometimes every other photo, it still gets very hot but then I've only been using it so far in this hot weather.

I actually prefer the feel of the phone with this mugen case, feels a lot nicer to hold, its weighty but after a couple of days I got used to the weight and the feel and do prefer it, although I still think it looks silly, others have laughed at my brick phone but held it themselves and thought it felt nice, interestingly it seems to weigh about the same as a colleagues iPhone 7 big screen thingy which really surprised me.

Charging seems to take the same amount of time as the cheap ebay battery which I find most confusing

I've had some weird vibration noise when audio is active that seems to be from the case not fitting 100% perfect, I'm currently using the black one so, will try the white case in a couple of weeks and see if there is a difference, its very infrequent, and pressing the case together with the phone stops it which makes me think its not fitting 100% and causing a vibration.

Its a shame mugen don't make a standard sized 950xl battery, as at least you know it should be a quality product and it comes with a 12 month warranty which interestingly is double what the battery came with when new, at least in the UK the battery only has a 6 month warranty which makes me think Microsoft knew it was a weak point of the phone? although that's just me taking a stab in the dark and being bitter about having a naff battery in the phone.

Would I recommend this? Absolutely! but not if you care about your phones looks, if function is better than fashion buy one today, if fashion is more important, get a mozo and enjoy the QI charging which is something I do sorely miss.
