[REVIEW] PolarCell 3400mah Note 4 Battery

[jphlag]

I know it's impossible for 6200mAh... but 4500 mah with not ? On Redmi 4 Xiaomi, battery is 4100 mah, and it's not more big..

I want a better battery for the Galaxy Note 4... my girlfriend is not happy with original battery.

I think you should better take this battery on ebay (I have one coming !) because on aliexpress you can have very bad surprises on batteries and electronics in general especially if it's for some very enticing offer (like this battery with almost 1000 mah more than the original)... And, by the way, if the original battery isn't good for your girlfriend, it's probably because it's getting old or because it's a counterfeit from the original battery from samsung .

Thanks !!

Je te réponds en français Je vais voir sur eBay oui pourquoi pas. Le Note 4 de ma copine a un an seulement, et elle a jamais était trop satisfaite et son téléphone s'éteint toujours à 20% de batterie. Un bug de la batterie ? On va voir sur ebay du coup.

Go on ebay !

Stop posting this in multiple threads. No amount of petitions are going to get the Note 4 an official update - spend your time learning how to install a custom ROM or get a newer phone - your only options.

I bought xiaomi mi bank 10000 mah and after testing was suprised that real capacity is only 6400 mah

I don't know if this the same for all battery banks, but when I bought a small Anker battery bank, I was told by Anker, I would only get about 2/3 of the capacity. Just because you can charge/store X mah, doesn't mean you will get that same amount back into your phone. Energy isn't being transferred with 100% efficiency. Energy gets lost in the charging process, powering the led/circuit board, etc.

I think that craftman battery is better then this one. I saw few tests and it was great by all parameters

Either talk about degradation of li-ion batteries is greatly exaggerated or these Polarcell batteries aren't that special. I've tested with Galaxy S4 and S5 but new Polarcell battery didn't seem to bring any more screen-on or standby time. On the contrary it seemed a bit weaker than 4 year old original samsung battery despite claiming to have 200mAh more capacity. How can that be possible as 4 year old Samsung battery should have lost about half of it's original capacity if Li-ion is degrading at the rate of 20%/2 years? Also I wonder why Samsung batteries are the only ones having manufacturing date stamped on them? Maybe because aftermarket battery manufacturers aren't that sincere and fool buyers with aged new batteries that have been sitting on the shelf for few years?

I'm using this battery for 1 week, its decent and ofcourse way better than samsung fakes. Actual capacity is 2800-3000mah.
