Thoughts on the ZeroLemon Galaxy S3 Extended Battery

As much as I hate to admit it, I’m almost completely lost without my phone. I did get around Italy for two weeks without the phone and maybe even liked it a bit, but once I got back to the states, my phone dependency returned. One of the drawbacks to using any smartphone is the lack of battery power. OEM manufacturers won’t design a huge battery because it detracts from the aesthetics of the phone. Enter the ZeroLemon 7000mAh extended battery for the Galaxy S3. This is a HUGE battery for the S3; it more than doubles the thickness of the phone. The battery comes with a replacement back made of TPU cover.

I’ve been using the ZeroLemon 7000mAh extended battery for about three months and this is an essential part of my toolkit now. Even when the OEM battery was new and strong in my S3, if I had a day of heavy use, or I was in a 4G city, or I was in the country where the phone constantly searched for service, I could easily run out of juice before the afternoon. It’s not that recharging my phone every night is such a pain, but having to worry about running out of juice is a pain.

A few tips and observations from my months with this battery.

First, if you are active outside and use your phone in an armband, this isn’t going to work. You’ll need to keep your smaller battery and back case handy, because I’m yet to find an armband that can hold this monster. But, if you know of one, feel free to add the link in the comments.

Next, the case is surprisingly protective of the phone. I’ve probably dropped it from 5 feet a few times since I installed this battery and the case cushions the strike and seems to really protect the phone from damage. The lip around the front of the screen also prevents scratches if you place the phone face down.  Related Note: Though I don’t have personal experience, you should avoid the white cover for this battery. I read a number of reviews that suggested it was easily soiled and terribly hard to clean.

Finally, a note on size. This seriously increases the size of your phone. Like, doubles it, maybe more. So, if you’re looking for a slimline phone, this isn’t your battery. You can pick up ZeroLemon’s Slimline Batteries for the S3, but stay away from this huge battery. I will say, the phone is no larger than with an Otterbox Defender for Samsung S3, but that might be too much for a lot of people.

If you’re in the market for a longlife battery, you’ll be hard pressed to find a better one than this, even at a new higher price. Recently, ZeroLemon has partnered with someone to sell their products on Amazon and this has caused a pretty significant price increase, from about $34 to $44, roughly. I bought my battery at the lower price and think it’s a great value. After 3 months, the battery life is still unbelievably strong, the case fits well and has protected my phone from numerous drops. I would highly recommend picking this battery up if you’re in the market for an extended battery for your S3.

  1. Love this ZeroLemon battery 7000mAh extended battery! I say that form follows function… or, how it looks is not as important as what it does. My OEM battery lasted about 8 hours (abysmal!), the ZL battery lasts about 48 hours.

  2. John,
    Thanks for the info. I agree about form following function and am glad to hear I’m not alone there. Glad you’re pleased with ZL’s battery here, I know I love it and am glad my experience isn’t singular.

  3. Hi Eric,
    updates on condition of your battery??
    I wanted to know how the battery works after 6 months…
    Its been 3 months since you wrote the artice..thnx

  4. Hello Bhavya,
    Thanks for asking. The battery is still doing well, though not lasting as long as when I first purchased it. That’s partially due, I’m sure, to my not always discharging the battery before recharging. But, where it previously lasted for 4 days on a full charge and normal use, now it’s good for 2-3, depending on use. Still a very good battery and much better than the OEM. I will say I think it’s worth the $34 I paid for it and now that the price is down to $40, I think I’d pick one up for my next phone too.

  5. Basically it’s gotten to the point where I wait for zerolemon to release a large capacity battery before i buy a new phone (galaxy s5 please!)

    As for cleaning the case, i found cleaning erasers somewhat successful, but not great. if there’s a cleaning solution i’d appreciate it

  6. Just bought the zerolemon for the Samsung S3 and using it as my business phone so this should be a good test of longivity. Recharge at about 2% seems to be the way to fly but I’m still only 12 hours into it. Excellent at this point! Will keep you posted.
