Nokia 1500 mAh Lithium-Ion Extra Capacity Battery for Nokia Phones

Summary: Long lasting but heavy
Review: I got this battery for my Nokia 5165 after my NiMH battery started to fade. Oddly enough, the extended lithium battery is less expensive than the regular (and I assume, slimmer) lithium battery, so I bought the cheaper one with more power, which is helpful when you forget to charge your phone. The charge does last a lot longer, but my phone now weighs a ton. That's the only thing that keeps me from giving it 5 stars.

Summary: Bah, get something else!
Review: I had the standard battery that came with the Nokia's 5185, that would barely last 36 hours while being on during that entire time. I got the 1500mAh Lithium-Ion so it would last longer than the 36 hours of always being on. It seems as though it doesn't want to last but 40-44 hours of always on and that is without zero usuage of phone calls/recieve, just on and sitting idle. But now if you turn it off for times that you know it won't be used at all then the time goes to 3 or 4 days before recharge. I'll be keeping it for that reason, but if I test the orginial one and last that long before a recharge then this thing blows......

Summary: For longer lasting battery, use Lithium-ion.
Review: I own a Nokia 5i60 phone, and use it quite often. When I bought this phone, it came with NiMH battery. This battery does not last long, so I bought a longer lasting Lithium-ion battery. With the NiMH battery, I had to recharge once every two weeks using it average of 15 minutes talk per day. Using the Litium-ion battery, I don't have to recharge until over two months. I recommend this battery to those big-time talker using Nokia phones. it's better to replace your NiMH battery with Lithium-ion.

Summary: GREAT Battery
Review: Seems to last forever in 'always on' use. Great talk times. I
recharge about once every six to 8 weeks. Not sure how 'each'
individual battery is 'made' (as I see some here unhappy)... but
MINE is the best thing that happened to my N6160.

Summary: BLS-4 - Performance Not Up to Par with Specifications!
Review: The BLS-4 came with my Nokia phone and the battery break-in period was followed as directed in owner's manual. However, after about 12 months the battery started showing signs of failing to hold a full charge. The BLS-4 will not hold a full charge for more than two days with only minimum use. The battery must have a limit on recharging cycles. I own another Nokia phone and it too has the BLS-4 battery, bought at the same time as the one noted above. This battery is still holding a full charge. I also followed the same break-in period as directed with this battery, the only difference in the two batteries is that this battery has not been recharged as much as the first. Maybe the first BLS-4 was defective. The battery worked well when it was new.
