Samsung Galaxy Note 3 N9000 Extended Battery, Kranich 9600mAh Extended Battery Replacement Full NFC Support with Black TPU Protection Case

Phenomenal, especially for the cost. The case is okay, good, even, better designed than I would expect, and includes plenty of access area around all ports, holes for all the mics, and a good cutaway for the pen. It's nice and grippy along the sides; a bit more slippery on the back than I'd prefer, but the case is otherwise utilitarian and inoffensive. I would say the phone's corners are moderately protected - don't drop it on purpose, but it'll take some normal daily abuse just fine.The total assembled size is perhaps ~3x thicker than the phone by itself - it's a big honking battery, after all. Remember the thick old-timey first generation Pocket PC devices? Thick like those.And dense, sort of like a Note 3-shaped slice taken out of a MacBook Pro.It's heavy, but the weight does not make the device unbalanced in one's hands, thankfully.Battery life seems appropriate of its 9600mah rating, as it lasts around 3x stock.With screen at high auto brightness and everything possible turned on - even unreasonable things like keeping cell data on while connected to wifi - I got 18 hours of total screen on time before the phone sighed indignantly (I imagine), and shut itself down to get a break from me (also imagined).In total, it lasted about 48h of uptime of intentionally heavy usage, which included Pokémon Go'ing and watching plenty of YouTube.TL;DR: Goodbye wall sockets, you can't control my life anymore!

This thing is amazing... I charge my Note 3 overnight and I don't have to even think about a charger until sometime in the afternoon the following day.. It does take about 5-6 hours to fully charge from dead but that's why it's easier to just plug it in at bedtime.. I routinely get 36+ hours of use out of it with steady web browsing, Iheart music, HD Youtube videos and a healthy dose of Google Maps and Navigation.. If it ever did lose its charge, I'd buy another one in a heartbeat!! The case is sturdy and fully protects the phone.. If you drop it, no part of the phone would touch the ground..

The product as advertised. Keep in mind, this battery is HUGE. so it almost triples your phone size, especially with the cover shipped with it. However, the battery is very nice and now I can use my phone normally the whole day without worry. I did not face any problems with camera, though because the phone is thick, any device to slide the phone in wont fit. i had a google cardboard, those stop fitting well. But it is worth the extra power

So far very impressive. Strangely enough the case fits perfectly which also happens to be the only thing holding the massive battery in place. Obviously it was well thought out as everything feels solid all the way down to the grips on the case which feel very secure when holding the phone. In addition, the case appears to be able to handle some minor drops and all the ports and buttons are accessible and work with ease respectively. As far as battery life, I've turned everything on and brightness to full and even with that I'd say that with normal use you could squeeze a week out of it without charging and heavy use probably 2.5 to 3 days (seriously, a single charge lasts a really really long time) As far as weight goes, ya it's heavier and bulkier but very self contained and fits in my pocket just fine. BTW: I am using a T-Mobile Galaxy Note 3 in the US.

Please note that Amazon made this right and fully refunded my purchase. Having been a massive Zerolemon fan for years, I thought I would try this battery out (Zerolemon battery does fit in this case).Not three weeks after having purchased, my battery went from a full charge down to zero. I know to power cycle and train the larger batteries and nothing worked. Unfortunately, Hyperion and Zerolemon are out of stock for the Note 3, so I have to use my old Zerolemon battery, which is better than nothing because I absolutely must have an extended battery.The great thing about Amazon is they always make it right. I just wish this battery had worked as promised.Update: Kranich customer service did reach out, which was appreciated, but I do know how to condition my battery so I'm confident I have been using it as recommended. Perhaps it was from a bad batch, but this battery did not work as I expected.

was ok for a while then stopped working had it tested the capacity was at 60% of what it was rated. Nooo one at KRANICH to answer any warranty question Amazon ended up helping me out (ty AMAZON).

Love it. My Note 3 stays charged for 3 DAYS - and I am on my cell all the time. It's big and clunky but the hidden benefit is that it protects the phone. I've gotten used the the size.

Just received it after 2 hours of use and it only went down like 7 or 8 %but remember u gotta calibrate the battery first like 5 cycles so the phone can get use to the new battery n give u a correct reading. But honestly it's huge..bigger then i expected but its sooo worth it especially for the cost. I love it so far. Only thing that worries me a little is the case. It fits perfect but on the bottom by the charger its kinda loose n maybe with time n wear it might get more loose. So hopefully it doesn't
