so far so good, it's been almost the end of the work day and it's still on 74%

i'm going to run it a few more days, before i give my recommendations

also i'll reset the counter tonight midnight, and let it run a whole normal daily cycle to see how long it can last without recharging.

then repeat the process with the stock 1500 mAh battery :D

but just for reference, the stock battery by this time of the day, is already way down to 50% or less

sorry shaky hands :p

[1850 mAh Extended Battery] Here are the pictures you've all been waiting for... :)
... old results, new ones will come on Monday, to capture the same info captured on the stock 1500 mAh test

[1500 mAh Stock Battery] Results are here
seems like the stock battery last slightly longer in a normal day routine than the extended battery, however by the same time in the morning the stock battery was already down to 63%

I hope this has more juice than the stock ones... normally anything the same size usually doesn't run any longer... heres to hoping it does!

There's been a lot of testing of aftermarket batteries... and they usually hold 70-80% of what they claim, so I'll be really surprised if this battery lasts any longer than the stock Samsung one. If it does, then that's great, I might pick one up, but I'm very skeptical... maybe a placebo effect?

The only way to really test is to get a voltmeter or do some controlled testing like video playback looping.

agreed, cant remember that site off the top of my head but it was pretty sad. However, if this battery indeed does better I would invest in one asap.

Better to risk $20 rather than $50 on Sedio's worthless 100 mah increase battery.

Picked up a set for myself. What is the correct way to cycle new batteries to give it the best performance ?

Lithium-ion is a low maintenance battery, an advantage that most other chemistries cannot claim. There is no memory and no scheduled cycling is required to prolong the battery's life.

http://batteryuniversity.com/learn/article/is_lithium_ion_the_ideal_battery


There is only one way to charge lithium-based batteries. The so-called 'miracle chargers', which claim to restore and prolong batteries, do not exist for lithium chemistries. Neither does super-fast charging apply. Manufacturers of lithium-ion cells have very strict guidelines in charge procedures and the pack should be charged as per the manufacturers "typical" charge technique.

Lithium-ion is a very clean system and does not need priming as nickel-based batteries do. The 1st charge is no different to the 5th or the 50th charge. Stickers instructing to charge the battery for 8 hours or more for the first time may be a leftover from the nickel battery days.

http://batteryuniversity.com/index.php/learn/article/charging_lithium_ion_batteries


Although lithium-ion is memory-free in terms of performance deterioration, batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem.

    I'm mostly curious about the application you use to track the health of the battery. May I have the name of that app?

    Also, what did you think about the build quality (or however you'd describe it) of these batteries? I'm worried about Chinese batteries scarring half of my face and that's not just to knock on Chinese people (I'm Chinese). I'm genuinely concerned about the combination of "made in China" and <$20.

    Does anyone know if this is the onliest 1850 mAh batterie that is compatible to ne ns?

    engrish much?
