SUNZOS Galaxy S3 Battery, 2100mAh Li-ion Replacement Battery for Samsung Galaxy S3 GT-I9300 (EB-L1G6LLU),GT-I9305 LTE, T999 (T-Mobile), I747 (AT&T), I535 (Verizon), L710 (Sprint)[Not for S3 mini]

This battery works well as a replacement for the original Samsung battery in my old S3. I also purchased a branded Samsung battery but that one did not work at all. It appeared to charge OK but would not allow the operating system to load on the phone so it was returned as faulty. This Sunzos battery however worked straight out of the box and seems to hold its charge well. Would buy again.

I did not realise how far gone my battery was until I replaced it with this one.First impressions are "Wow" it came 53% full and I am still running the battery down as per instructions after four days. My old battery would have been dead by now, very impressed so far, I cannot comment on how long they will last as I have not had it long enough but judging how it is performing at the moment I am impressed.There was no problem with replacing the old battery and the bonus was it came with a charging cable for the phone.18th Feb 19 Having now had the battery a little while it shows no sign of losing power suddenly.I am impressed so far ,excellent battery..

A good value replacement S3 battery. Takes a couple of recharge cycles to fully wake the battery up, but one stone is very usable. Would recommend.

I'm delighted with this battery - so far.I had searched for ages, and messaged several suppliers of Galaxy SIII batteries and was struggling to find one who had one which would work with my SIII NEO, so I was thrilled (if a little sceptical) to be assured by SUNZOS-UK that their battery was compatible, but for the price it was a no brainer. It arrived next-day and I was delighted to discover that it worked perfectly (It was delivered with a 38% charge). In the two weeks since it was fitted it has been fully discharged and recharged twice, as per instructions, and is currently showing 79%. That's a huge improvement on the one it replaced which, with limited usage, needed charged daily .It's too soon to rate its Longevity, but Im fairly confident that it will last a while, given its performance so far.NOTE TO SUNZOS-UK: INCLUDE SIII NEO (GT-193011) IN YOUR ITEM DESCRIPTION.

Has given this old phone a new lease of life. Easily lasts more than a day and often two.

I bought this battery to replace one which was not holding its charge for any longer than about 10 hours. I'm sorry to say that this replacement battery was even worse, despite following the instructions and fully discharging it and re-charging for the first 5 days. I returned it for a refund.

No complaints.

My phone was not holding a charge and I was expecting to pay a high price for a new battery. This was not the case and reading all the reviews, I went for this battery. So far I have not been disappointed. Considering this includes a 3 year guarantee, I am impressed.Ordering through Amazon is always easy.Delivery was quickPackaging was good.All in all, very happy.

Comparada con otras baterías clónicas para el mismo modelo de móvil, esta dura mucho más, casi un día completo con un uso normal. Buen producto para alargar la vida útil de un Samsung Galaxy S3 aún en buenas condiciones pero cuya batería ya no daba más de si.
